Effect of peroral endoscopic myotomy on esophagogastric junction physiology in patients with achalasia

Pneumatic dilation and laparoscopic Heller myotomy improve parameters of esophageal function such as lower esophageal sphincter (LES) pressure, esophageal emptying, and esophagogastric junction (EGJ) distensibility. To evaluate the effect of peroral endoscopic myotomy (POEM) on esophagogastric function. Prospective trial. Endoscopy department at a university hospital. All consecutive patients aged >17 years with achalasia and an Eckardt score of ≥3. Before and 3 months after POEM, 10 consecutive patients underwent esophageal manometry, timed barium esophagograms, and EndoFLIP as well as an EGD. Eckardt symptom score, LES resting pressure, centimeters of barium stasis, EGJ distensibility, and reflux esophagitis. Compared with scores before POEM, patient symptom scores were significantly reduced (1, interquartile range [IQR 0-1] vs 8 [IQR 4-8]; P = .005). LES pressure decreased significantly (6.0 mm Hg [IQR 2.6-7.4] vs 19.0 mm Hg [IQR 13.0-28.0]; P = .008). Esophageal emptying increased significantly, and a 5-minute barium column measured 2.3 cm (IQR 0-3.2 cm) versus 10.1 cm (IQR 5.7-10.8 cm; P = .005). EGJ distensibility increased significantly (6.7 mm(2)/mm Hg [IQR 3.8-16.6] vs 1.0 mm(2)/mm Hg [IQR 0.4-2.3]; P = .02) at 50 mL. In 6 of 10 patients, reflux esophagitis was seen. Of these patients, 3 reported reflux symptoms. Small number of patients, short-term follow-up. POEM improves esophagogastric function and suggests favorable long-term results based on Eckardt score, esophageal manometry, esophageal emptying, and EGJ distensibility. Long-term follow-up of larger series will determine whether the high rate of reflux esophagitis affects the clinical application of POE

Endoscopic closure of acute perforations of the GI tract: a systematic review of the literature

Surgical repair of endoscopic perforations of the GI tract used to be the standard, but immediate, secure endoscopic closure has become an attractive alternative treatment with the potential to reduce morbidity and mortality. We aimed to perform a systematic review of the medical literature on endoscopic closure of acute iatrogenic perforations of the GI tract. A systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Available medical literature from 1966 through November 2013. Patients with an acute perforation after an endoscopic procedure that was closed endoscopically. Endoscopic closure of an acute perforation of the GI tract. Clinically successful endoscopic closure. In our search, we identified 726 studies, 702 of which had to be excluded. Twenty-four cohort studies (21 retrospective, 3 prospective) were included in the analysis. No randomized trials were identified. Overall, the methodological quality was low. The 24 studies included described 466 acute perforations in which endoscopic closure was attempted. Successful endoscopic closure was achieved in 419 cases (89.9%; 95% CI, 87%-93%). Successful closure was achieved in 90.2% (n = 359; 95% CI, 87%-93%) of cases by using endoclips, in 87.8% (n = 58; 95% CI, 78%-95%) by using the over-the-scope-clip, and in 100% (n = 2) by using a metal stent. Low methodological quality of included studies. This systematic review suggests that endoscopic perforation closure is a safe and effective alternative for surgical intervention in selected cases; however, the overall methodological quality was low. Prospective, true consecutive studies are needed to define the definitive role of endoscopic closure of perforation

Single-port versus multiport laparoscopic ileocecal resection for Crohn's disease

Several case series have demonstrated the feasibility of single-port laparoscopic ileocecal resection in Crohn's disease. However, only a few studies compared the single-port with a multiport laparoscopic ileocecal approach. The aim of this study was to compare short term surgical outcome parameters between single-port and multiport laparoscopic ileocecal resections for Crohn's disease. Twenty-one patients who underwent single-port laparoscopic ileocecal resection between March 2010 and September 2012 were prospectively registered. A matched comparison on a 1:2 basis was performed with patients who underwent multiport laparoscopic ileocecal resection from January 1999 to March 2010. Matching parameters were BMI, length of diseased bowel resected and the presence of fistulas. Endpoints were the length of postoperative hospital stay, operative time, conversions, complications, postoperative pain scores and postoperative analgesia consumption. Twenty-one patients undergoing single-port resection were matched to 42 patients undergoing multiport resection. The postoperative stay (4 days, iqr 4-5 vs. 5 days, iqr 4-6; p=0.033), operative time (103 min, iqr 94.0-121.0 vs. 123.5 min, iqr 100.0-157.0; p=0.036) and morphine use on the first postoperative day (12.5 mg, iqr 5.0-33.3 vs. 28 mg, 15.0-50.0; p=0.012) differed significantly. Postoperative pain scores and complications were similar in both groups. This study was limited by potential selection bias. Single-port laparoscopic ileocecal resection is safe and feasible in Crohn's disease and is associated with less need for pain medication postoperatively as opposed to multiport laparoscopic ileocecal resectio

Peroral endoscopic myotomy for the treatment of achalasia: an international prospective multicenter study

Pilot studies have indicated that peroral endoscopic myotomy (POEM) might be a safe and effective treatment for achalasia. We performed a prospective, international, multicenter study to determine the outcomes of 70 patients who underwent POEM at 5 centers in Europe and North America. Three months after POEM, 97% of patients were in symptom remission (95% confidence interval, 89%-99%); symptom scores were reduced from 7 to 1 (P < .001) and lower esophageal sphincter pressures were reduced from 28 to 9 mm Hg (P < .001). The percentage of patients in symptom remission at 6 and 12 months was 89% and 82%, respectively. POEM was found to be an effective treatment for achalasia after a mean follow-up period of 10 month

Gallstones as a cause in presumed acute alcoholic pancreatitis:observational multicentre study

Background: Data on the incidence and clinical relevance of gallstones in patients with suspected acute alcoholic pancreatitis are lacking and are essential to minimize the risk of recurrent acute pancreatitis. The aim of this study was to assess the incidence of gallstones and the associated rate of recurrent acute pancreatitis in patients with presumed acute alcoholic pancreatitis. Methods: Between 2008 and 2019, 23 hospitals prospectively enrolled patients with acute pancreatitis. Those diagnosed with their first episode of presumed acute alcoholic pancreatitis were included in this study. The term gallstones was used to describe the presence of cholelithiasis or biliary sludge found during imaging. The primary outcome was pancreatitis recurrence during 3 years of follow-up. Results: A total of 334 patients were eligible for inclusion, of whom 316 were included in the follow-up analysis. Gallstone evaluation, either during the index admission or during follow-up, was performed for 306 of 334 patients (91.6%). Gallstones were detected in 54 patients (17.6%), with a median time to detection of 6 (interquartile range 0-42) weeks. During follow-up, recurrent acute pancreatitis occurred in 121 of 316 patients (38.3%), with a significantly higher incidence rate for patients with gallstones compared with patients without gallstones (59% versus 34.2% respectively; P &lt; 0.001), while more patients with gallstones had stopped drinking alcohol at the time of their first recurrence (41% versus 24% respectively; P = 0.020). Cholecystectomy was performed for 19 patients with gallstones (36%). The recurrence rate was lower for patients in the cholecystectomy group compared with patients who did receive inadequate treatment or no treatment (5/19 versus 19/34 respectively; P = 0.038). Conclusion: Gallstones were found in almost one in every five patients diagnosed with acute alcoholic pancreatitis. Gallstones were associated with a higher rate of recurrent pancreatitis, while undergoing cholecystectomy was associated with a reduction in this rate
