The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Guidelines Committee develops evidence-based surgical guidelines. Involvement of patient partners is important to ensure patient concerns and values are adequately addressed and incorporated. This standard operating procedure (SOP) for the process of patient partner involvement within the guidelines is described here.

This document outlines the SAGES Patient Partners SOP to involve patient partners in a consistent and reproducible manner.

SAGES has now developed a SOP to include patient partners so that patient views are represented in current guidelines.

Guidelines must be patient centric and in order to do so must include patient partners. The SAGES Guidelines Patient Engagement Update to Standard operating Procedure aims to provide an outline for systematically doing so.

Gastro-esophageal reflux disease (GERD) is a chronic condition, with 50-80% of patients experiencing recurrence within one year following completion of initial treatment. The present study aimed to estimate recurrence rate and treatment response in GERD patients treated with proton pump inhibitor.

A total of 207 symptomatic GERD patients, which were confirmed by endoscopy from July 2008 till January 2009, were enrolled. They were divided into non-erosive reflux disease (NERD) group and erosive reflux disease (ERD) group by endoscopic findings. Patients were treated with lansoprazole 15 mg (NERD group) or 30 mg (ERD group) once daily for 8 weeks. The presence of symptoms was assessed in each patient at baseline and post-treatment using a questionnaire. Subsequent symptomatic recurrence on the cessation of therapy in each improved patients was checked by telephone survey or outpatient interview.

Ninety-four patients and 113 patients were first diagnosed with NERD and ERD, respectively. The mean post-treatment follow-up period was 24.4+/-8.5 weeks. Recurrence rate was 40.0% (NERD, 43.8%; ERD, 37.1% (p=0.224)). Recurrence time was 10.1+/-5.8 weeks (NERD 9.6 weeks; ERD, 10.6 weeks (p=0.444)). Regarding the symptom improvement after 8 week therapy with lansoprazole, 89.4% (NERD, 85.1%; ERD, 92.9% (p=0.056)) of total patients were symptomatically improved.

Forty percentage of GERD patients recurred within 6 months following the completion of 8 week therapy with lansoprazole. Recurrence rate, recurrence time, and rate of symptom improvement were not significantly different between NERD group treated with half dose and ERD group treated with full dose lansoprazole.

The clinical features of patients reflux esophagitis without any symptoms have not been clearly demonstrated. This study evaluated the clinical features of patients with endoscopy-positive reflux esophagitis, who did not complain of symptoms, as detected by brief questioning by nursing staffs. Eight thousand and thirty-one patients not taking medication for gastrointestinal disease, were briefly asked about the presence of heartburn, dysphagia, odynophagia and acid regurgitation by nursing staffs before endoscopy for assessment of esophagitis utilizing the Los Angeles Classification. Endoscopically, 1199 (14.9%) patients were classified as positive for reflux esophagitis. The endoscope positive subjects who complain heartburn were 539/1199 (45.0%).The endoscope positive subjects who do not complain symptoms were 465 in 1199 positive reflux esophagitis (38.8%). We compared endoscopic positive subjects without any complain by brief question by nursing staffs to endoscopic positive subjects with heartburn. Male gender, no obesity, absence of hiatus hernia, and low-grade esophagitis were associated with endoscopy-positive patients who do not complain of symptoms. The results of this study indicated correct detection of clinical symptoms of reflux esophagitis might be not easy with brief questioning by nursing staffs before endoscopic examination.

Patients with gastroesophageal reflux disease (GERD) often complain of dysphagia and are frequently found to have intraepithelial eosinophils on esophageal biopsy.

The aim of this study was to investigate the relationship between dysphagia and the number of intraepithelial eosinophils in patients with GERD.

Review of all patients studied in our esophageal function laboratory from 1999 to 2007 identified 1,533 patients with increased esophageal acid exposure. Patients who complained of dysphagia without mechanical or motor causes were identified and divided into three groups based on whether dysphagia was their primary, secondary or tertiary symptom. A control group consisted of randomly selected GERD patients with no dysphagia. The highest number of intraepithelial eosinophils per high-power field (HPF) in biopsies from the squamocolumnar junction (SCJ) and esophageal body was compared across groups.

There were 71 patients with unexplained dysphagia. Dysphagia was the primary symptom in 13 (18%), secondary symptom in 34 (48%), and tertiary symptom in 24 (34%) patients. The number of eosinophils differed between the four groups, with the highest number in those with dysphagia as the primary symptom (P = 0.0007). This relationship persisted whether biopsies were from the SCJ (P = 0.0057) or esophageal body (P = 0.0096).

An association exists between the number of intraepithelial eosinophils and dysphagia in GERD patients, with the highest number of eosinophils in those with the primary symptom of dysphagia.

Gastrointestinal (GI) disease is one of the leading aetiologies of chest pain in a primary care setting. The aims of the study are to describe clinical characteristics of GI disease causing chest pain and to provide criteria for clinical diagnosis.

We included 1212 consecutive patients with chest pain aged 35 years and older attending 74 general practitioners (GPs). GPs recorded symptoms and findings of each patient and provided follow up information. An independent interdisciplinary reference panel reviewed clinical data of each patient and decided about the aetiology of chest pain. Multivariable regression analysis was performed to identify clinical predictors that help to rule in or out the diagnosis of GI disease and Gastroesophageal Reflux Disease (GERD).

GI disease was diagnosed in 5.8% and GERD in 3.5% of all patients. Most patients localised the pain retrosternal (71.8% for GI disease and 83.3% for GERD). Pain worse with food intake and retrosternal pain radiation were associated positively with both GI disease and GERD; retrosternal pain localisation, vomiting, burning pain, epigastric pain and an average pain episode < 1 hour were associated positively only with GI disease. Negative associations were found for localized muscle tension (GI disease and GERD) and pain getting worse on exercise, breathing, movement and pain location on left side (only GI disease).

This study broadens the knowledge about the diagnostic accuracy of selected signs and symptoms for GI disease and GERD and provides criteria for primary care practitioners in rational diagnosis.

This study was aimed to evaluate the correlation between dysphagia, detected by nursing staff in a brief interview and endoscopic findings in reflux esophagitis.

A total of 8,031 Japanese subjects without medication for gastrointestinal disease were briefly asked about the presence of heartburn, dysphagia, odynophagia, and acid regurgitation by nursing staff before endoscopy for assessment of esophagitis utilizing the Los Angeles Classification.

The grade of endoscopic esophagitis was not equivalent to symptoms of dysphagia in 8,031 subjects. We evaluated the characteristics of subjects who complained of only dysphagia. Univariate analysis indicated that non-smoking, and non-drinking females were associated with a higher risk for dysphagia, and multivariate analysis indicated the gender was associated with dysphagia. There was no association of dysphagia with herniation and distribution of age.

This study indicated that dysphagia was not equivalent to the endoscopic findings according to a brief interview by nursing staff and that dysphagia might be more common in females and those who do not smoke or drink.

For diagnosis and quantitation of gastroesophageal reflux disease, a number of different examinations are available. The simplest are the patient's history and complaints as well as the proton pump inhibitor test; both methods have a positive predictive value of 65% to 70%. Esophagogastroduodenoscopy is the gold standard for differentiation between erosive and nonerosive reflux disease. Biopsy does not enhance the significance of endoscopy except for proof of Barrett's epithelium or malignant degeneration. Twenty-four-hour pH monitoring has the highest sensitivity and specificity for the diagnosis of gastroesophageal reflux disease. Barium swallow provides only additional information concerning hiatal hernia or stenosis. Manometry can clarify lower esophageal sphincter insufficiency or motility disorders of the tubular esophagus. However, the available studies show that manometry has no influence on postoperative outcome after fundoplication. The indication for medical therapy can primarily be based only on the history and complaints of the patient. As surgical therapy affords a high degree of diagnostic accuracy, at least endoscopy and 24-h pH monitoring are necessary for indication.

Gastro-oesophageal reflux disease (GERD) encompasses a wide range of disorders defined by either reflux-related symptoms or by complications of gastro-oesophageal reflux. The most characteristic GERD symptoms are heartburn and acid regurgitation. Patients with these symptoms are in most cases easily identifiable and diagnosis is made on the basis of symptoms alone. For patients with a decreased frequency of heartburn, diagnosis is more difficult, and endoscopy is the single best test for diagnosis of GERD. A major difference between the West and Asia is the frequency of endoscopic investigation. In Japan, the earlier high prevalence of stomach cancers resulted in the increased use of endoscopy as an investigational tool for dyspeptic symptoms and today endoscopy continues to be widely available as a diagnostic tool. However, the overall sensitivity of endoscopy for the diagnosis of GERD is less than 50% since not all patients will have oesophagitis at the time of endoscopy. Ambulatory pH monitoring is therefore a frequently used diagnostic tool as it allows correlation between reflux events and symptoms, and is especially useful in patients with atypical or extraoesophageal symptoms. Oesophageal manometry is also an excellent test to evaluate oesophageal function and to measure sphincter pressure and while it may not provide an unequivocal diagnosis of GERD it is a useful tool with which to evaluate oesophageal function.
