Choledochoduodenostomy (CDD) is performed to treat choledocholithiasis (CDL) cases where endoscopic stone removal is difficult. Recognizing CDD characteristics is important for CDL treatment planning.

A total of 116 patients, including 33 patients ≥ 80 years old (29 with previous total gastrectomy, 19 with previous distal gastrectomy, 20 with built-up stones, 19 with periampullary diverticulum, 10 with confluence stones, 8 with repetitive recurrent stones, 4 with hard stones, 3 with endoscopic retrograde cholangiography [ERC] not available due to lack of cooperation, 2 with a history of pancreatitis post-ERC, and 2 in whom ERC could not be performed due to a disturbed anatomy) underwent CDD for CDL. Postoperative complications and long-term outcomes were evaluated.

The in-hospital mortality rate was 0%. The morbidity (grade ≥ IIIA according to the Clavien-Dindo classification) rates in the elderly (≥ 80 years old) and non-elderly (51-79 years old) patients were 3.0% (1/33) and 2.4% (2/83), respectively (p = 0.85). Long-term complications included cholangitis in eight (7%) patients, of which three cases were repetitive and seven had an operative history of total or distal gastrectomy. The incidence of postoperative cholangitis after total or distal gastrectomy was 15% (7/48), which was significantly higher than that involving other causes (1.5%, 1/68; p < 0.01). Two patients with cholangitis after total gastrectomy experienced early recurrence of lithiasis at 2 and 9 months after surgery.

CDD is safe, even in elderly patients. However, a history of total gastrectomy or distal gastrectomy may increase the incidence of postoperative cholangitis.

The occurrence of long-term bilioenteric anastomotic stenosis can readily induce liver atrophy and hyperplasia, thereby causing significant alterations in the anatomical and morphological aspects of the liver. This condition significantly hampers the accuracy of preoperative imaging diagnosis, while also exacerbating the complexity of surgical procedures and the likelihood of complications.

A 60-year-old female patient was admitted to the hospital presenting with recurring epigastric pain accompanied by a high fever. The patient had a history of cholecystectomy, although the surgical records were not accessible. Based on preoperative imaging and laboratory examination, the initial diagnosis indicated the presence of intrahepatic calculi, abnormal right liver morphology, and acute cholangitis. However, during the surgical procedure, it was observed that both the left and right liver lobes exhibited evident atrophy and thinness. Additionally, there was a noticeable increase in the volume of the hepatic caudate lobe, and the original bilioenteric anastomosis was narrowed. The anastomosis underwent enlargement subsequent to hepatectomy. As a consequence of the presence of remaining stones in the caudate lobe, the second stage was effectively executed utilizing ultrasound-guided percutaneous transhepatic catheter drainage. Following the puncture, three days elapsed before the drain tip inadvertently perforated the liver, leading to the development of biliary panperitonitis, subsequently followed by pulmonary infection. The patient and her family strongly refused operation, and she died.

The hepatic atrophy-hypertrophy complex induces notable alterations in the anatomical structure, thereby posing a substantial challenge in terms of imaging diagnosis and surgical procedures. Additionally, the long-term presence of hepatic fibrosis changes heightens the likelihood of complications arising from puncture procedures.

To distinguish clinical features, safety and efficiency of endoscopic retrograde cholangiopancreatography (ERCP) in patients after bilioenteric anstomosis based on retrospectively analyzed clinical data and endoscopy procedures.

Data extracted from patients after bilioenteric anstomosis due to biliary disease treated with ERCP from January 2005 to December 2021 in the Department of Gastroenterology, Peking University Third Hospital were retrospectively analyzed. Clinical data and endoscopic pictures were reevaluated and analyzed. The patients were divided into three groups, including the patients with choledochoduodenostomy (CDD), Roux-en-Y hepaticojejunostomy (RYHJ) and Whipple. Differences between ERCP success and failure were conducted.

In the study, 89 cases with 132 ERCP procedures were involved, 9-80 years old, median 57 years old, containing 4 CDD, 30 RYHJ, 54 Whipple and 1 bile duct ileocecal anastomosis patients; The time between ERCP and surgery were 30 (1-40), 2.75 (0.5-14), 2 (0.3-19), and 10 years, respectively; The time between surgery and symptom were 240 (3-360), 12 (1-156), 22 (0-216), and 60 months, respectively. Fifty percent of CDD could succeed only under local anaesthesia, RYHJ (96.7%) and Whipple (100.0%) needed under general anaesthesia (P < 0.001). Successful first entry rates of CDD, RYHJ and Whipple were 100.0%, 40.0% and 77.8%, respectively. After changing the endoscopy type, successful entry rate could increase to 43.3% of RYHJ and 83.3% of Whipple. The successful entry rate of different anastomotic methods was significant (P < 0.001). The cannulation success rates of CDD, RYHJ and Whipple were 100.0%, 53.8% and 86.7% respectively, with significant difference between the groups (P=0.031). ERCP success rates of CDD, RYHJ and Whipple were 100.0%, 33.3% and 78.8% respectively, with significant difference between the groups (P < 0.001). Complications were found in 23.9% (21/88) patients, including infection (14.8%), pancreatitis (9.2%), bleeding (3.4%), and perforation (2.3%) ranked by incidence. Causes of ERCP in post bilioenteric anstomosis were anastomotic stenosis (50.0%, benign 39.3%, malignant 10.7%), choledocholithiasis (37.5%) and reflux cholangitis (12.5%). Anastomotic method was the only predicting factor of ERCP success in patients after bilioenteric anstomosis (OR=7, 95%CI: 2.591-18.912, P < 0.001).

ERCP in post bilioenteric anstomosis patients with gastrointestinal reconstruction need general anaesthe-sia, with good safety and efficiency. The successful rate of RYHJ was significantly lower than Whipple. Anastomotic method was the only predicting factor of ERCP success.

Gallstone disease and complications from gallstones are a common clinical problem. The clinical presentation ranges between being asymptomatic and recurrent attacks of biliary pain requiring elective or emergency treatment. Bile duct stones are a frequent condition associated with cholelithiasis. Amidst the total cholecystectomies performed every year for cholelithiasis, the presence of bile duct stones is 5%-15%; another small percentage of these will develop common bile duct stones after intervention. To avoid serious complications that can occur in choledocholithiasis, these stones should be removed. Unfortunately, there is no consensus on the ideal management strategy to perform such. For a long time, a direct open surgical approach to the bile duct was the only unique approach. With the advent of advanced endoscopic, radiologic, and minimally invasive surgical techniques, however, therapeutic choices have increased in number, and the management of this pathological situation has become multidisciplinary. To date, there is agreement on preoperative management and the need to treat cholelithiasis with choledocholithiasis, but a debate still exists on how to cure the two diseases at the same time. In the era of laparoscopy and mini-invasiveness, we can say that therapeutic approaches can be performed in two sessions or in one session. Comparison of these two approaches showed equivalent success rates, postoperative morbidity, stone clearance, mortality, conversion to other procedures, total surgery time, and failure rate, but the one-session treatment is characterized by a shorter hospital stay, and more cost benefits. The aim of this review article is to provide the reader with a general summary of gallbladder stone disease in association with the presence of common bile duct stones by discussing their epidemiology, clinical and diagnostic aspects, and possible treatments and their advantages and limitations.

Impact of previous history of choledochojejunostomy (PCJ) on the incidence of organ/space surgical site infection (SSI) after hepatectomy remains unclear. The aim of this study was to investigate the incidence and causes of SSI after hepatectomy.

Patients who underwent hepatectomy of ≤1 Couinaud's sector between January 2011 and September 2019 were retrospectively analyzed. Incidence of and risk factors for organ/space SSI (Clavien-Dindo grade ≥2) after hepatectomy were investigated.

Among 750 hepatectomies, 18 patients (2.4%) had a medical history of PCJ. Incidence of organ/space SSI was higher in patients with PCJ (50%) than in those without PCJ (3%, P < 0.001), and the trend was consistent even after estimated propensity score matched cohort. Multivariate analysis showed PCJ was a strong risk factor for organ/space SSI (grade ≥2), with the highest odds ratios (OR) among all other clinicopathological risk factors (OR, 32.25; P < 0.001). Among hepatectomies with PCJ, pneumobilia (OR, 12.25; P = 0.015), operation time ≥171 min (OR, 12.25; P = 0.016), and liver steatosis (OR, 24.00; P ≤ 0.005) were associated with organ/space SSI after hepatectomy.

Previous history of choledochojejunostomy was a strong risk factor for organ/space SSI after hepatectomy. The high rate of organ/space SSI after hepatectomy with PCJ might be attributed to intrahepatic bile duct contamination, increased operation time, and histological liver steatosis.

Introduction Cholelithiasis usually can be managed successfully by endoscopic sphincterotomy. Choledochoduodenostomy (CDD) is one of the surgical treatment options but its acceptance remains debated because of the risk of reflux cholangitis and sump syndrome. The aim of this study was to assess the current features and outcomes of patient undergoing CDD. Patients and methods We retrospectively analysed the surgical results of consecutive 130 patients treated by CDD between 1991 and 2013 and excluded five cases with a malignant disorder. Indications for surgery included endoscopic management where stones were difficult or failed to pass and primary common bile duct stones with choledochal dilatation. Incidences of reflux cholangitis, stone recurrence, pancreatitis or sump syndrome were investigated and the data between end-to-side and side-to-side CDD were compared. Results Reflux cholangitis and stone recurrence was 1.6% (2/125) and 0% (0/125) of cases by CDD. There is no therapeutic-related pancreatitis in CDD. Sump syndrome was not also observed in side-to-side CDD. Conclusions This study is a first comparative study between end-to-side and side-to-side CDD. The surgical outcomes for CDD treatment of choledocholithiasis were acceptable. The incidence of reflux cholangitis, stone recurrence, pancreatitis and sump syndrome was very low.

Recurrent bile duct stones is the most common complication after gallstone surgery and the incidence is about 4-24%. Sphincter of Oddi laxity will lead to duodenal content flow into the bile or pancreatic duct. Patients with recurrent bile duct stones and Oddis sphincter laxity were intractable. Here we sought to present the possible and helpful surgical treatments for such patients. Prospective randomized clinical trial are needed for evaluating the outcome of surgical treatments.

About 9% of the Brazilian population has gallstones and the incidence increases significantly with aging. The choledocholithiasis is found around 15% of these patients, and a third to half of these cases presented as asymptomatic. Once the lithiasis in the common bile duct is characterized through intraoperative cholangiography, the laparoscopic surgical exploration can be done through the transcystic way or directly through choledochotomy.

To evaluate the results and outcomes of the laparoscopic treatment of common bile duct lithiasis.

Seventy consecutive patients were evaluated. They prospectively underwent the treatment of the lithiasis in the common bile duct and the exploration ways were compared according to the following parameters: criteria on their indication, success in the clearance, surgical complications. It was verified that about ½ of the choledocholithiasis carriers did not show any expression of predictive factors (clinical antecedents of jaundice and/or acute pancreatitis, compatible sonographic data and the pertaining lab tests). The laparoscopic exploration through the transcystic way is favored when there are no criteria for the practice of primary choledochotomy, which are: lithiasis in the proximal bile duct, large (over 8 mm) or numerous calculi (multiple calculosis).

The transcystic way was employed in about 50% of the casuistic and the choledochotomy in about 30%. A high success rate (around 80%) was achieved in the clearance of the common bile duct stones through laparoscopic exploration. The transcystic way, performed without fluoroscopy or choledochoscopy, attained a low rate of success (around 45%), being 10% of those by transpapilar pushing of calculi less than 3 mm. The exploration through choledochotomy, either primary or secondary, if the latter was performed after the transcystic route failure, showed high success rate (around 95%). When the indication to choledochotomy was primary, the necessity for choledochoscopy through choledochotomy to help in the removal of the calculi was 55%. However, when choledochotomy was performed secondarily, in situations where the common bile duct diameter was larger than 6 mm, the use of choledochoscopy with the same purpose involved about 20% of the cases. There was no mortality in this series.

The laparoscopic exploration of the common bile duct was related to a low rate of morbidity. Therefore, the use of laparoscopy for the treatment of the lithiasis in the common bile duct depends on the criteria for the choice of the best access, making it a safe procedure with very good results.

With the advent of endoscopic retrograde choledochoduodenostomy, the need for choledochoduodenostomy to treat common bile duct obstruction is less common, but occasionally required.

Patients considered for laparoscopic choledochoduodenostomy secondary to benign conditions between 1999 and 2009 at a single institution were included. Charts were retrospectively reviewed for preoperative, operative, and long-term outcomes data.

Twenty patients were identified; 15 with chronic choledocholithiasis causing benign biliary obstruction or chronic recurrent cholangitis, 3 with chronic relapsing pancreatitis, and 2 with distal common bile duct strictures. Mean operative time was 270 min. No major operative complications were reported. Five patients with severe adhesions or portal hypertension required conversion to laparotomy. Median hospital stay was 6 days (range, 2-32). Postoperatively, three (20%) patients completed laparoscopically and three (66.7%) patients converted to laparotomy had complications. In addition, one death due to myocardial infarction was reported 4 weeks after hospital discharge. With an average follow-up of 21 months, only one patient (5%) developed recurrent symptoms.

Laparoscopic choledochoduodenostomy is a useful technique in patients with benign, refractory common bile duct obstruction. This technically demanding procedure is feasible; however, the associated comorbidities in this complex group of patients result in a relatively high complication rate.

To determine the long-term results of choledochodudenostomy in patients with benign billiary obstruction.

This prospective study was conducted at Sheri Kashmir Institute of Medical Sciences Srinagar Kashmir, India over a period of 10 years from January 1997 to December 2007. The total number of patients who underwent choledochoduodenostomy during this period was 270. On the basis of etiology of biliary tract obstruction, patients were divided into a calculus group, an oriental cholangiohepatitis group, a benign biliary stricture group and others. Patients were followed for a variable period of 13 mo to 15 years.

Choledochoduodenostomy (CDD) with duo-denotomy was performend in four patients. CDD with removal of T- tube, CDD with left hepatic lobectomy and CDD with removal of intra biliary ruptured hydatid was performed in three patients each. In the remaining patients only CDD was performed. Immediate post operative complications were seen in 63 (23%) patients, while long-term complications were seen in 28 (11%) patients, which were statistically significant. Three patients died during hospitalization while four patients died in the late post-operative period.

Our conclusion is that CDD is safe and produces good long term results when a permanent biliary drainage procedure is required.

Choledochoduodenostomy (CDD) has been shunned by some surgeons for the management of the benign distal common bile duct stricture due to the potential complication of "sump syndrome." The feared sump syndrome is theorized to occur from bile stasis and reflux of duodenal contents into the terminal common bile duct with bacterial overgrowth, resulting in cholangitis or hepatic abscess. The true incidence and resultant morbidity of sump syndrome, however, are not well defined.

With the approval of the Institutional Review Board, a retrospective chart review of all patients undergoing choledochoduodenostomy for benign disease at a single institution between 1994 and 2008 was undertaken. Data were collected with particular attention to operative indications, perioperative course, and long-term results. Long-term outcomes were assessed through clinical reports at outpatient follow-up, emergency room visits, and hospital readmissions.

Seventy-nine patients underwent side-to-side CDD for benign diseases over the 15-year period [51 (65%) men; mean age, 52 years (standard deviation (SD), 12)]. Indications for surgery included chronic pancreatitis (80%), choledocholithiasis (11%), and cholangitis (4%). Patients presented with abdominal pain (80%), nausea/vomiting (30%), and jaundice 13%. Sixty-one patients (77%) underwent an additional procedure at the time of their CDD, including lateral pancreaticojejunostomy (26%). There was no perioperative mortality. Postoperative complications occurred in 15 (19%) patients, including intraabdominal abscess (26%), wound infection (20%), and biliary leakage (13%). The mean hospital stay was 9.7 days (SD, 6.9). The mean follow-up was 6.2 years (SD, 4.2). There was no occurrence of cholangitis. Two patients (2.5%) developed hepatic abscess, which was managed by antibiotics and image-guided percutaneous drainage.

CDD is a safe and effective method of decompressing the distal common bile duct in benign pancreatobiliary disease. Long-term results are acceptable, with sump syndrome being a rare occurrence.

With the advent of interventional endoscopic procedures and with growing experience of laparoscopic surgery, the indications for open biliary procedures have become limited. This prospective study reviews the indications of open choledochoduodenostomy for benign biliary diseases and presents the short-term and long-term outcomes of this procedure in the present minimally invasive surgical era.

Side-to-side choledochoduodenostomy was carried out for various benign obstructive pathologies of the biliary tract. The various parameters recorded were the demographic data, indications for surgery, early and late complications and the long-term outcome of the procedure.

Results of choledochoduodenostomy on 54 consecutive patients over a 9-year period are presented. The mean age was 49.7 years with a male to female ratio of 1:2.6. Thirty (55.5%) patients presented with obstructive jaundice and 42.6% had cholangitis. Overall hospital morbidity was 13% with zero mortality. After a mean follow up of 7.8 years, 96.3% patients had 'good' or 'fair' and 3.7% experienced 'poor' results. No recurrent disease or biliary malignancy was observed.

Open biliary drainage procedures may still be indicated in select patients where the facility or expertise for minimally invasive biliary procedures is not available. Choledochoduodenostomy remains an effective biliary drainage procedure with acceptable morbidity and mortality, especially in the high-risk and elderly population. The procedure should be regarded as an essential in the general surgical knowledge and training.

This study audited the clinical outcome of a cohort of patients with choledocholithiasis treated with long-term biliary stenting in order to determine the feasibility of this practice.

Over 2 years, 83 patients with symptomatic choledocholithiasis were treated with long-term stenting because they either refused further treatments or were medically unfit for further procedures after the initial endoscopic retrograde cholangiopancreatography (ERCP). Recurrence of clinical events, need for stent change, morbidity, and mortality were analyzed. As a secondary analysis, published data on long-term biliary stenting were reviewed.

ERCP and biliary stenting were successful in all cases with no complications. The mean follow-up was 19 months (1-103 months). The median number of ERCPs performed was 1 (1-4). The mean duration of stent patency was 12.4 months (1-54.8 months). A total of 28 clinical events (cholangitis, 71%) occurred in 24 patients during follow-up, for a late complication rate of 33.7%. ERCP was repeated and the stents changed on 15 occasions in 11 asymptomatic patients with abnormal liver function tests detected on routine follow-up. No biliary-related mortality occurred. Review of published data revealed a mean late complication rate of 22.4% (0%-64%), a biliary-related mortality rate of 3.5% (0%-21.1%), and a nonbiliary-related mortality rate of 20.8% (0%-60.3%).

Long-term biliary stenting is a feasible option for patients who decline or are medically unfit for further elective endoscopic or surgical procedures. Close follow-up is mandatory to detect and treat late complications.

In the setting of chronic pancreatitis, pancreatic ductal obstruction, and ductal leak, pseudocyst formation and biliary obstruction present many challenges for endoscopists. Although chronic pancreatitis has a variety of clinical manifestations, most commonly patients present with intermittent or chronic abdominal pain. Recent studies suggest stenting of pancreatic ductal strictures has a significant impact on reducing chronic pain. The removal of ductal calculi, presumably from relieving obstruction, also improves abdominal pain. When the site of leak is bypassed, ductal leaks may be cured by endoscopic stenting. Multiple plastic bile duct stents to treat chronic pancreatitis-associated bile duct stricture can delay the need for surgery. Although these endoscopic techniques have been beneficial for many patients, further study is warranted to better define their role in chronic pancreatitis compared with well-established surgical techniques.

Choledochojejunostomy (CJS) is commonly used for biliary reconstruction in liver transplantation for primary sclerosing cholangitis (PSC). We alternatively performed choledochoduodenostomy (CDS) and side-to-side choledochodocholedochstomy in a large cohort of patients. Fifty-one patients with PSC, transplanted between 1988 and 2000, were analyzed retrospectively. Biliary reconstruction was CDS in 25 (49%), CJS in 20 (39%) and CC in 6 transplantations (12%). Biliary leaks occurred in the early follow-up (< or =41 days) only in CDS patients (20%). However, in the late follow-up (>4 months), stricturing of anastomosis was found once in CDS (4%) and CJS (5%). Later (>9 months), intrahepatic bile duct strictures were diagnosed in four CDS (16%), one CJS (5%) and one CC (17%) patient(s). In 48% of CDS (12/25), 60% of CJS (12/20) and 17% of CC (1/6) at least one incidence of cholangitis was observed. Overall, biliary complication rates were significantly higher in CDS (40%) than CJS (10%) and CC (17%); of those none in CC and 12% in CDS were anastomosis-related. Graft/patient survival showed no significant differences among groups. Based on our results we consider CJS the standard method for biliary reconstruction in PSC; however, in selected cases where CJS is difficult to accomplish because of previous surgery or for retransplantation, CDS may present an alternative technique.

Biliary stricture and duodenal obstruction have been increasingly recognized as complications of chronic pancreatitis. The anatomical relationship of the distal common bile duct and the duodenum with the head of the pancreas is the main factor for their involvement in chronic pancreatitis. In hospitalized patients with pancreatitis, the incidence of biliary stricture and duodenal obstruction is reported to be about 6% and 1.2%, respectively. For patients requiring an operation for chronic pancreatitis the incidence increases to 35% for biliary stricture and 12% for duodenal obstruction. Fibrosis around the distal common bile duct can cause stenosis with obstruction of bile flow. Clinically, the presentation of these patients ranges from being asymptomatic with elevated alkaline phosphatase or bilirubin, or both, to being septic with cholangitis. Jaundice, cholangitis, hyperbilirubinemia, and persistent elevation of serum alkaline phosphatase occur more frequently in patients with pancreatitis with a biliary stricture. A twofold elevation of alkaline phosphatase is a marker of possible common duct stenosis in patients with chronic pancreatitis. The incidence of both biliary cirrhosis and cholangitis in these patients is about 10%. ERCP reveals a characteristic long, smoothly tapered stricture of the intrapancreatic common bile duct. In duodenal obstruction, the factors that convert self-limiting edema to chronic fibrosis and stricture formation are unknown, but ischemia superimposed on inflammation may be the major cause. These patients present with a prolonged history of nausea and vomiting. Barium studies typically show a long constricting lesion of the duodenum, and endoscopy reveals reactive inflammatory changes in a narrowed duodenum. Operation is indicated in patients with common bile duct strictures secondary to chronic pancreatitis when there is evidence of cholangitis, biliary cirrhosis, common duct stones, progression of stricture, elevation of alkaline phophatase and/or bilirubin for over a month, and an inability to rule out cancer. The operation of choice is either choledochoduodenostomy or choledochojejunostomy. A cholecystoenterostomy is less favored because of its higher failure rate (23%). Endoscopic stenting plays a role in patients who are unfit for surgery, but it is not recommended as definitive therapy. For duodenal obstruction, failure to resolve the obstruction with 1-2 weeks of conservative therapy is an indication for bypass. The operation of choice is a gastrojejunostomy. Not uncommonly, combined obstruction of the pancreatic duct, common bile duct, and duodenum will develop. Combined drainage procedures or resection are used to manage these problems.

The long-term outcome after endoscopic papillotomy is poorly defined. The aim of this study was to determine the long-term results of this method in the treatment of common duct calculi and to determine which prognostic factors are associated with the relapse of biliary symptoms.

Between 1985 and 1988, 223 consecutive (149 women, mean age 67.9 years) patients underwent endoscopic papillotomy for duct stones; 127 had already undergone cholecystectomy or underwent this operation during the same hospitalization. Follow-up data were obtained retrospectively from the patients and patients' relatives and general practitioners.

The procedure was successful in 217 of 223 cases (97%), of which 203 were followed-up; 2 patients died in the first month after treatment (0.89%). Mean follow-up for the 201 patients was 6.2 years, during which 31 relapsed (15%). Three significant prognostic factors for late complications were identified in a multivariate analysis. The recurrence rate of biliary symptoms in patients who were left with an in situ gallbladder was 20.2%, and 11% for those whose gallbladder was removed (p = 0.04). Patients with a bile duct 15 mm or greater in diameter were more prone to recurrence of symptoms than those with a bile duct 10 mm or less in diameter (41% vs. 10%, p = 0.025) and were especially at higher risk to develop recurrent stones (19.5% vs. 4.9%, p = 0.019). Stone recurrence, but not biliary symptoms as a whole, was more frequent in patients with a peripapillary diverticulum (p = 0.035).

The long-term results of endoscopic papillotomy are comparable with those of surgical techniques. The prognostic factors associated with relapse of biliary symptoms as a whole are gallbladder left in situ and choledochal diameter. Bile duct size and peripapillary diverticula are associated with recurrent bile duct stones.

An uncommon and late complication of side-to-side choledochoduodenostomy (CDD), the 'sump syndrome', developed in a patient 4 years after surgery. Recurrent right upper abdominal pain, fever with chills and rigors and latterly, mild jaundice made her seek repeated hospital admissions which were treated successfully with antibiotics. During the last admission, ultrasonography, endoscopic retrograde cholangiography (ERC), computerized scanning (CT) and hepatic iminodiacetic acid (HIDA) scan using Tc99m confirmed multiple intrahepatic calculi with proximal dilatation, debris in the distal blind segment and delayed excretion through the CDD. At surgery, the choledochoduodenostomy was taken down and a Rouxen-Y hepaticojejunostomy (RHJ) was fashioned after ductal clearance. The closed end of the Roux loop was placed subcutaneously for subsequent percutaneous access for cholangiography and removal of calculi. She is asymptomatic and well 28 months after surgery.

Little is known about the long-term effects of endoscopic biliary sphincterotomy.

We retrospectively evaluated the rate of late complications after endoscopic sphincterotomy (EST) for bile duct stones. Patients had to meet the following inclusion criteria: (1) treated between 1976 and 1980, (2) complete stone removal after EST, (3) prior cholecystectomy or elective cholecystectomy within 2 months after EST, and (4) 60 years old or younger at the time of ERCP. A total of 100 patients were identified. Information was obtained from general practitioners and patients by telephone. Patients completed a postal questionnaire and a blood sample was obtained for liver function tests.

Information was obtained for 94 patients (in the majority of cases [87%] from multiple sources). There were 26 men and 68 women with a mean age of 51 years at the time of ERCP (range, 23 to 60 years). Early complications (< 30 days) occurred in 14 patients (15%). One patient died of a retroperitoneal perforation secondary to EST. During a median period of 15 years (range, 3 to 18 years), 22 patients (24%) developed a total of 36 late complications. There were 21 patients with symptoms of recurrent bile duct stones and one patient with biliary pancreatitis. Other late complications, such as recurrent ascending cholangitis or malignant degeneration, were not observed. An ERCP was performed in 20 of the 22 patients with late complications and demonstrated bile duct stones in 13, combined with stenosis of the EST opening in 9 patients. Late complications were initially managed endoscopically and/or conservatively. One patient underwent surgery after failed endoscopic treatment and one patient died of cholangitis before she could undergo an ERCP. Twelve other patients died of unrelated causes during follow-up.

After EST for bile duct stones, late complications occur in a significant proportion of patients. Stone recurrence remains the most important problem, but can in general be managed endoscopically.

A retrospective evaluation was made of the long-term results of endoscopic stenting in 58 patients with benign biliary stricture due to chronic pancreatitis. Immediate relief of jaundice and cholestasis was achieved in all patients after endoscopic stent insertion. Median follow-up was 49 months. Five (9 per cent) of the 58 patients had complications following therapeutic endoscopic retrograde cholangiopancreatography. Late stent-related complications occurred in 37 (64 per cent) of 58 patients. There were no deaths. Sixteen (28 per cent) of the 58 patients had regression of the biliary stricture and permanent removal of the stent. Forty-two patients had persistent biliary stricture: 26 had continued stenting and 16 underwent surgical procedures. Early morbidity after surgery was found in six of 16 patients, with no deaths. Postoperative relief of jaundice was achieved in 15 of the 16 patients. In conclusion, endoscopic stenting and surgery are both effective treatments for biliary stricture in patients with chronic pancreatitis. Endoscopic stenting is associated with fewer early complications. However, late stent-related complications remain a major limitation. Endoscopic stenting offers definitive treatment in more than one-quarter of patients (28 per cent).

Demands for less invasive, more cost-effective therapy have revolutionized the management of gallstones over the past 10 years. There are no reliable methods of permanently reversing the pathophysiologic defects that cause gallstones. Open cholecystectomy (OC), the gold standard for managing symptomatic cholelithiasis, has been largely replaced by laparoscopic cholecystectomy (LC), which has the advantages of a minimal hospital stay and quicker return to work. Other adjunctive therapies, limited in applicability to selected patients, include oral bile acid therapy (BAT), dissolutional agents, and extracorporeal shock wave lithotripsy. Choledocholithiasis (CDL), formerly managed exclusively with surgical common duct exploration, is increasingly treated with therapeutic biliary endoscopy. Methods of laparoscopic common bile duct exploration are being developed. Optimal algorithms for applying these techniques to patients undergoing LC are evolving. In a sense, the solution to all, or certainly most, gallstones now can be seen through a scope.
