Laparoscopic cholecystectomy (LC) is one of the most widely practiced surgical procedures in abdominal surgery. Patients undergo LC during general anaesthesia; however, in recent years, several studies have suggested the ability to perform LC in patients who are awake. We report a case of awake LC and a literature review.

A 69-year-old patient with severe pulmonary disease affected by cholelithiasis was scheduled for LC under regional anaesthesia. We first performed peridural anaesthesia at the T8-T9 level and then spinal anaesthesia at the T12-L1 level. The procedure was managed in total comfort for both the patient and the surgeon. The intra-abdominal pressure was 8 mmHg. The patient remained stable throughout the procedure, and the postoperative course was uneventful.

Evidence has warranted the safe use of spinal and epidural anaesthesia, with minimal side effects easily managed with medications. Regional anaesthesia in selected patients may provide some advantages over general anaesthesia, such as no airway manipulation, maintenance of spontaneous breathing, effective postoperative analgesia, less nausea and vomiting, and early recovery. However, this technique for LC is not widely used in Europe; this is the first case reported in Italy in the literature. Regional anaesthesia is feasible and safe in performing some types of laparoscopic procedures. Further studies should be carried out to introduce this type of anaesthesia in routine clinical practice.

Epidural anesthesia (EA) today has been used extensively in surgical procedures and the management of pain associated with midwifery and chronic pain. This type of anesthesia can be done in different technical, physiological, and pharmacological ways. The aim of this study was to compare the effects of thoracic EA with general anesthesia (GA) on hemodynamic changes and its complications in patients underwent laparoscopic colonoscopy.

This clinical trial study was conducted on 80 patients undergoing laparoscopic cholecystectomy with EA or GA based on inclusion and exclusion criteria. The patients were randomly divided into two groups of 40 and changes in blood pressure, systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR), and arterial blood oxygen saturation were measured. The incidence of nausea, vomiting, chills, and itching in the two groups was recorded. The analysis was performed descriptively and also using t-test and Chi-square tests.

The results showed that the mean of SBP and DBP, HR, and arterial blood oxygen saturation and the incidence of nausea and vomiting was statistically significant (P < 0.05) between the two groups at 4, 6, and 12 h after anesthesia and it was higher in a group of GA. There was no significant difference in shivering and itching between the two groups (P > 0.05).

The results of this study indicated that thoracic EA in patients with laparoscopic cholecystectomy has significant effects on factors such as SBP and DBP and arterial blood oxygen saturation. Furthermore, EA has fewer complications than GA, and it is the preferable approach.

The aim of this randomized controlled study is to compare the safety and efficacy of thoracic spinal versus thoracic epidural anesthesia for open nephrectomy in patients with obstructive/restrictive lung disease.

Sixty patients with mild to moderate chronic obstructive/restrictive lung disease undergoing open nephrectomy were randomized into two groups, 30 patients each. The thoracic spinal group (TSA) group received ultrasound guided mid-thoracic spinal anesthesia, and the thoracic epidural group (TEA) group received thoracic epidural anesthesia. All blocks were performed at the T7-T8. Hemodynamics, visual analogue scale score, sensory and motor block profile as well as any adverse events, and patient satisfaction were all reported.

Both blocks were successfully performed and were effective for surgery in all patients, with the exception of only one patient in TSA group who needed to receive general anesthesia even after IV midazolam because of extreme anxiety and was excluded from the study analysis. The sensory block ranges were quiet close, with T2-T5 for the TSA group and T3-T6 for the TEA group as the upper level and L3-L5 as the same lower level. The values for the onset time and the duration of sensory and motor blocks were lower in TSA group. There were no statistically significant differences existed in intraoperative VAS, and hemodynamics between the two groups. Postoperative adverse effects were negligible and insignificant, with no case reporting any neurological sequel.

Ultrasound guided thoracic spinal anesthesia can be performed safely and effectively for open nephrectomy in patients with obstructive/restrictive lung disease with the potential for an early ambulation and great patient satisfaction.

Traditionally, laparoscopic procedures have been performed under general anesthesia. Spinal anesthesia is an effective alternative to general anesthesia. However, one of the intraoperative complications of performing laparoscopic surgery under spinal anesthesia is shoulder pain. This study aimed to compare the effect of transcutaneous electrical nerve stimulation (TENS) with fentanyl on pain relief in patients who underwent gynecologic laparoscopy under spinal anesthesia.

We conducted a prospective randomized clinical trial from May 2016 to March 2017. A sample of patients who underwent gynecological laparoscopy under spinal anesthesia was recruited. If they had shoulder pain, they randomly received either transcutaneous electrical nerve stimulation (TENS) or 50 mg of fentanyl. Pain intensity was measured using the single item visual analogue scale (VAS-10 cm) immediately before and 5, 10, 20, and 30 minutes after treatment. Also, the effect of higher doses of analgesia on pain relief was analyzed.

In all, 80 patients (40 patients in each group) were entered into the study. The mean pain intensity score was 9.02 ± 1.32 in the TENS group and 8.95 ± 1.33 in the fentanyl group at baseline (P = 0.80). Repeated measures analysis of variance indicated that there was no significant difference on overall pain scores between the two treatment groups adjusted for age, BMI, total analgesia used, and baseline pain score (F (1, 74) = 1.44, P = 0.23). The use of analgesic drugs in the TENS group was significantly higher than the fentanyl group (P = 0.01). In addition, we found that nine patients (22.5%) complained of nausea/vomiting in the TENS group compared to thirteen patients (32.5%) in the fentanyl group (P = 0.31).

The findings indicated that TENS was not superior to fentanyl for pain relief in laparoscopic surgery. It seems that the correct use of TENS parameters might merit further investigation. This trial is registered with: IRCT2016031216765N3.

Laparoscopic cholecystectomy (LC) is usually performed under general anesthesia. Recently, laparoscopic cholecystectomy under regional anesthesia has become popular, but this creates a serious risk of thromboembolism because of pneumoperitoneum, anesthesia technique, operative positioning, and patient-specific risk factors.

This randomized controlled trial compares the effects of two different anesthesia techniques in laparoscopic cholecystectomy on coagulation and fibrinolysis.

This randomized prospective study included 60 low-risk patients with deep vein thrombosis (DVT) who underwent elective LC without thrombo-emboli prophylaxis. The patients were randomly divided into two groups according to the anesthesia technique: the general anesthesia (group 1, n = 30) and spinal epidural anesthesia (group 2, n = 30) groups. Measurement of the prothrombin time (PT), thrombin time (TT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), and blood levels of D-dimer (DD) and fibrinogen (F) were recorded preoperatively (pre), at the first hour (post 1) and 24 h (post 24) after the surgery. These results were compared both between and within the groups.

The mean age was 51.5 ±16.7 years (range: 19–79 years). Pneumoperitoneum time was similar between group 1 (33.8 ±7.8) and group 2 (34.8 ±10.4). The TT levels significantly declined postoperatively in both groups. The levels of PT, aPTT, INR, D-dimer and fibrinogen dramatically increased postoperatively in both groups.

While there was not any DVT, there was a significant decline in TT. There was a dramatic rise in the PT, INR, D-dimer, fibrin degradation products (FDP), and fibrinogen following LC. This may be attributed to the effects of pneumoperitoneum and anesthesia techniques on portal vein flow.

Laparoscopic cholecystectomy (LC) is usually performed under the general anesthesia (GA). Aim of the study is to investigate the availability, safety and side effects of combined spinal/epidural anesthesia (CSEA) and comparison it with GA for LC.

Forty-nine patients who have a LC plan were included into the study. The patients were randomly divided into GA (n = 25) and CSEA (n = 24) groups. Intraoperative and postoperative adverse events, postoperative pain levels were compared between groups.

Anesthesia procedures and surgeries for all patients were successfully completed. After the organization of pneumoperitoneum in CSEA group, 3 patients suffered from shoulder pain (12.5%) and 4 patients suffered from abdominal discomfort (16.6%). All these complaints were recovered with IV fentanyl administration. Only 1 patient developed hypotension which is recovered with fluid replacement and no need to use vasopressor treatment. Postoperative shoulder pain was significantly less observed in CSEA group (25% vs. 60%). Incidence of postoperative nausea and vomiting (PONV) was less observed in CSEA group but not statistically significant (4.2% vs. 20%). In the group of CSEA, 3 patients suffered from urinary retention (12.5%) and 2 patients suffered from spinal headache (8.3%). All postoperative pain parameters except 6th hour, were less observed in CSEA group, less VAS scores and less need to analgesic treatment in CSEA group comparing with GA group.

CSEA can be used safely for laparoscopic cholecystectomies. Less postoperative surgical field pain, shoulder pain and PONV are the advantages of CSEA compared to GA.

Rapid and uneventful postoperative recovery following general anesthesia in morbidly obese patients undergoing bariatric surgery may offer challenges to anesthesiologists. With improved surgical techniques and shorter pneumoperitoneum, regional anesthesia may be considered for this laparoscopic procedure in selected cases.

The first patient was a 60-year-old male (body mass index: 39 kg/m²) who was scheduled for laparoscopic sleeve gastrectomy. The second patient was a 46-year-old female (body mass index: 47 kg/m²) who was scheduled for laparoscopic gastric bypass. After standard intraoperative monitoring was applied, epidural anesthesia was performed at thoracic level T9–T10. Surgical technique modification included insufflation of CO₂ at a low flow rate and avoidance of orogastric tube use. During the procedure, both patients breathed spontaneously without difficulty. One hypotension episode occurred and was successfully treated with a 12-mg bolus of ephedrine in case 1. Shoulder pain occurred intraoperatively in case 2 and was successfully treated with a 50-μg bolus of fentanyl. Postoperatively, 2 mg epidural morphine was administered for postoperative analgesia. Both patients were satisfied with the anesthesia technique and was discharged uneventfully.

This anesthetic technique may maintain pre-operative respiratory function, increase alertness, and reduce the use of rescue analgesics, which is crucial for optimal outcomes in morbidly obese patients. Conversion of epidural anesthesia to general anesthesia may be required if patients can not tolerate the laparoscopic procedure (e.g. intolerable shoulder pain) or the increased respiratory rate during pneumoperitoneum leading to difficulty in performing laparoscopic surgery. Further studies are needed to elucidate this issue.

General anesthesia is widely used for laparoscopic bariatric surgery, but epidural anesthesia may be a viable alternative to general anesthesia in selected cases. Further prospective studies may be required to elucidate the relative advantages and disadvantages of epidural anesthesia in this surgical population.

Traditionally laparoscopic cholecystectomy is done under general anesthesia. But recently there is a growing interest to get it conducted under central neuraxial blockade. We conducted a clinical study comprising bupivacaine alone or a combination of bupivacaine and clonidine (2 μg/kg) in thoracic epidural anesthesia for laparoscopic cholecystectomy (LC). The aim was to attenuate the undesirable hemodynamic changes due to pneumoperitoneum (PNO) and achieve a better qualitative blockade.

After taking approval from Institutional Ethical Committee, 50 adult patients of ASA grade I and II were divided into two groups; group A where bupivacaine was given with 2 μg/kg of clonidine (Cloneon, Neon) and in group B bupivacaine (Anawin, Neon) was given with 1 ml of saline as placebo. Thoracic epidural was given at the T₉-T₁₀ or T₁₀-T₁₁ interspace to obtain a block of T₄-L₂ dermatome. Hemodynamic parameters like heart rate (HR), noninvasive blood pressure (NIBP), respiratory rate (RR), electrocardiogram (ECG), oxygen saturation (SpO₂) and arterial pressure of carbon dioxide (PaCO₂) were monitored and readings were recorded before and 10 minutes (min.) after the blockade and then at 5 min, 15 min and 30 min after PNO and 15 min after exsufflation.

All the parameters of the patients in group A remained stable but the patients of group B showed an increase in mean arterial pressure (MAP) and HR at 5, 15 and 30 min after PNO and 15 min after exsufflation as compared to Group A. PaCO₂, SpO₂ and RR values in both the groups were comparable. In group A, two patients complained of shoulder pain while in group B12 patients complained of shoulder pain.

Thoracic epidural anesthesia for LC is a satisfactory alternative technique in selected cases. Addition of clonidine (2 μg/kg) to bupivacaine produces better qualitative anesthetic conditions. It prevents hemodynamic perturbations produced by pneumoperitoneum and also decreases the incidence of shoulder pain. Thus we strongly advocate the incorporation of clonidine as an adjuvant in thoracic epidural anesthesia for LC.

Laparoscopic cholecystectomy (LC) is normally performed under general anesthesia. But of late this operation has been tried under regional anesthesia successfully without any added complications like epidural anesthesia.

The aim of the study was to study the feasibility of performing LC under epidural anesthesia in normal patients so that the benefits could be extended to those high-risk patients having symptomatic gallstone disease and compromised cardio-pulmonary status where general anesthesia is contraindicated.

In all, 20 patients with the American Society of Anesthesiologist's class I or II were enrolled in the study. The level of epidural block and satisfaction score, both for the patient and the surgeon, were noted in the study.

The LC was performed successfully under epidural anesthesia in all but two patients who had severe shoulder pain in spite of giving adequate analgesia and were converted to general anesthesia.

The LC can be performed safely under epidural anesthesia with understanding between patient and surgeon. However, careful assessment of complications in the patients should be done to make the procedure safer.

Cholecystectomy represents the second most common surgery during pregnancy. Both general and regional anesthetic techniques have been successfully used for cholecystectomy in pregnant patients. Authors present here a case of a pregnant patient carrying twin gestation who underwent cholecystectomy, which is not frequently encountered by the anesthesiologists. This report enumerates the perioperative issues relating to anesthesia given to a pregnant patient in addition to emphasizing the importance of multidisciplinary approach when such a case is encountered.
