Abstract
Background and study aims
The aim of the current study was to review the outcomes of a large-scale international registry on endoscopic ultrasound-guided gallbladder drainage (EGBD) that ...encompasses different stent systems in patients who are at high-risk for cholecystectomy.
Patients and methods
This was a retrospective international multicenter registry on EGBD created by 13 institutions around the world. Consecutive patients who received EGBD for several indications were included. Outcomes include technical and clinical success, unplanned procedural events (UPE), adverse events (AEs), mortality, recurrent cholecystitis and learning curve of the procedure.
Results
Between June 2011 and November 2017, 379 patients were recruited to the study. Technical and clinical success were achieved in 95.3 % and 90.8 % of the patients, respectively. The 30-day AE rate was 15.3 % and 30-day mortality was 9.2 %. UPEs were significantly more common in patients with EGBD performed for conversion of cholecystostomy and symptomatic gallstones (
P
< 0.001); and by endoscopists with experience of fewer than 25 procedures (
P
= 0.033). Both presence of clinical failure (
P
= 0.014; RR 8.69 95 %CI 1.56 – 48.47) and endoscopist experience with fewer than 25 procedures (
P
= 0.002; RR 4.68 95 %CI 1.79 – 12.26) were significant predictors of 30-day AEs. Presence of 30-day AEs was a significant predictor of mortality (
P
< 0.001; RR 103 95 %CI 11.24 – 944.04).
Conclusion
EGBD was associated with high success rates in this large-scale study. EGBD performed for indications other than acute cholecystitis was associated with higher UPEs. The number of cases required to gain competency with the technique by experienced interventional endosonographers was 25 procedures.
Abstract
Background and aim
Accurate estimation of the distance to the gastroesophageal junction (GEJ) through a tunnel during per oral endoscopic myotomy (POEM) is technically challenging. The ...methods currently employed are often insufficient, and resultant errors may lead to incomplete myotomy and/or prolonged procedure times. Our hypothesis states that the additional distance while traversing the tunnel is directly proportional to the widest esophageal diameter; and is calculated by the formula X = Y + CZ (X = distance to the GEJ through the tunnel, Y = distance to the GEJ through the lumen, Z = widest esophageal diameter, C = arithmetic constant). This study evaluates the validity and accuracy of this hypothesis.
Patients and methods
This was a prospective single-center study with 80 patients, 12 in the pilot group and 68 in the study group. In the pilot group, Y was recorded during esophagogastroduodenoscopy (EGD) before POEM, Z on barium swallow/contrast enhanced computed tomography (CECT), and X was measured during POEM. Using the formula, mean C (SD) was calculated. In the study group, ‘C’ was substituted in the equation to predict the GEJ distance through the tunnel (Xp) before POEM. The operator was blinded to Xp and recorded the true Xt during POEM. The correlation between Xp and Xt was calculated.
Results
In the pilot group, the mean distances (cm, SD) for X, Y, and Z were 42.58 (3.33), 39.83 (3.08), and 4.39 (1.16), respectively. The calculated mean C was 0.63 (0.11). In the study group, the mean distances (cm, SD) for Y, Z, Xp, and Xt were 40.45 (2.58), 4.99 (1.43), 43.57 (2.68), and 43.54 (2.78), respectively. The Xp and Xt values demonstrated a high correlation (r = 0.97,
P
= 0.000).
Conclusions
Formula X = Y + CZ reliably predicts the GEJ distance through a tunnel during POEM. It is user friendly and requires no additional resources.
Abstract
Background and study aims
Per-oral endoscopic myotomy (POEM) is associated with a short-term clinical response of 82 % to 100 % in treatment of patients with achalasia. Data are limited on ...the long-term durability of the clinical response in these patients. The aim of this study was to determine the long-term outcomes of patients undergoing POEM for management of achalasia.
Methods
This was a retrospective multicenter cohort study of consecutive patients who underwent POEM for management of achalasia. Patients had a minimum of 4 years follow-up. Clinical response was defined by an Eckardt score ≤ 3.
Results
A total of 146 patients were included from 11 academic medical centers. Mean (± SD) age was 49.8 (± 16) years and 79 (54 %) were female. The most common type of achalasia was type II, seen in 70 (47.9 %) patients, followed by type I seen in 41 (28.1 %) patients. Prior treatments included: pneumatic dilation in 29 (19.9 %), botulinum toxin injection in 13 (8.9 %) and Heller myotomy in seven patients (4.8 %). Eight adverse events occurred (6 mucosotomies, 2 pneumothorax) in eight patients (5.5 %). Median follow-up duration was 55 months (IQR 49.9–60.6). Clinical response was observed in 139 (95.2 %) patients at follow-up of ≥ 48 months. Symptomatic reflux after POEM was seen in 45 (32.1 %) patients, while 35.3 % of patients were using daily PPI at 48 months post POEM. Reflux esophagitis was noted in 16.8 % of patients who underwent endoscopy.
Conclusion
POEM is a durable and safe procedure with an acceptably low adverse event rate and an excellent long-term clinical response.
Background: Helicobacter pylori (H. pylori) infection is a risk factor for peptic ulcer. There have been no studies addressing environmental and dietary risk factors in western India. We conducted a ...case control study enrolling peptic ulcer patients in Pune, India. Materials and Methods: Risk factors for peptic ulcer and H. pylori infection were assessed in a participant interview. H. pylori status was assessed from stool by monoclonal antigen detection. Results: We enrolled 190 peptic ulcer, 35 stomach cancer patients, and 125 controls. Fifty-one percent (180/350) of the participants were infected with H. pylori. Lower socioeconomic status (SES) odds ratio (OR): 1.10, 95% confidence interval (CI): 1.02-1.39, meat consumption (OR: 2.35, 95% CI: 1.30-4.23), smoking (OR: 2.23, 95% CI: 1.24-4.02), eating restaurant food (OR: 3.77, 95% CI: 1.39-10.23), and drinking nonfiltered or nonboiled water (OR: 1.05, 95% CI: 1.01-1.23) were risk factors for H. pylori infection. H. pylori infection (OR: 1.70, 95% CI: 1.03-2.89), meat (OR: 1.10, 95% CI: 1.02-1.75), fish (OR: 1.05, 95% CI: 1.02-1.89) consumption, and a family history of ulcer (OR: 1.20, 95% CI: 1.08-1.60) were risk factors for peptic ulcer. Consumption of chili peppers (OR: 0.20, 95% CI: 0.10-0.37) and parasite infestation (OR: 0.44, 95% CI: 0.24-0.80) were protective against H. pylori infection. Conclusion: H. pylori infection is associated with peptic ulcer. Lower SES, consumption of restaurant food, meat, nonfiltered water, and smoking are risk factors for H. pylori. Consumption of meat, fish, and a family history of peptic ulcer are risk factors for peptic ulcer. Consumption of chili peppers and concurrent parasite infestation appear to be protective against H. pylori.

Abstract
Background
Peroral endoscopic myotomy (POEM) is an established treatment for achalasia cardia; however, post-POEM gastroesophageal reflux (GER) remains a significant problem. Concomitant ...endoscopic fundoplication following POEM (POEM + F) was recently described to reduce post-POEM GER. This single-center study reports short-term outcomes of POEM + F.
Methods
This was a retrospective analysis of a prospectively maintained database of patients undergoing POEM + F. Abstracted data included demographics, achalasia type, pre-POEM Eckardt score, prior therapy, follow-up. Follow-up assessment was 3-monthly for 1 year and included post-POEM Eckardt score, GerdQ score, wrap integrity and esophagitis on esophagogastroduodenoscopy, and pH studies. GER was defined according to Lyon Consensus.
Results
25 patients underwent POEM + F (mean age 40.1 years standard deviation (SD) 13.7; 12 females). POEM + F was technically successful in 23/25 (92.0 %). Significant dysphagia improvement was seen in all 25 patients (mean pre- and post-POEM Eckardt scores 8.21 SD 1.08 and 0.1 SD 0.3, respectively;
P
= 0.001). Mean total procedure and fundoplication times were 115.6 (SD 27.2) minutes and 46.7 (SD 12.4) minutes, respectively; times reduced significantly after the initial five cases. Median follow-up was 12 months (interquartile range IQR 9–13). Intact wrap was seen in 19/23 (82.6 %). GER (abnormal esophageal acid exposure time EAET) was seen in 2/18 (11.1 %) and there was one reported GerdQ > 8. Borderline GER (asymptomatic grade A esophagitis, normal EAET) was identified in 4/22 (18.2 %). Three (12.0 %) minor delayed adverse events occurred but required no intervention.
Conclusions
POEM + F was safe and reproducible. At 12 months’ follow-up, incidence of post-POEM + F GER was low and acceptable.
