Abstract
Background and study aims
EUS-guided gastroenterostomy (EUS-GE) is a novel procedure that potentially offers long-lasting luminal patency without the risk of tumor ingrowth/overgrowth. This ...study compared the clinical success, technical success, adverse events (AEs), length of hospital stay (LOHS) and symptom recurrence in EUS-GE versus SGJ.
Methods
This was a multicenter international retrospective comparative study of EUS-GE and SGJ in patients with malignant gastric outlet obstruction (GOO) who underwent either EUS-GE or SGJ. EUS-GE was performed using lumen apposing metal stents.
Results
A total of 93 patients with malignant GOO treated with either EUS-GE (n = 30) or SGJ (n = 63) were identified. Peritoneal carcinomatosis was present in 13 (43 %) patients in the EUS-GE group and 7 (11 %) patients in the SGJ group (
P
< 0.001). Although the technical success rate was significantly higher in the SGJ group as compared to the EUS-GE group (100 % vs. 87 %,
P
= 0.009), the clinical success rate was not different (90 % vs. 87 %,
P
= 0.18, OR 0.8, 95 %CI 0.44 – 7.07). The rate of AEs was lower in the EUS-GE group, but the difference was not statistically significant (16 % vs 25 %,
P
= 0.3). The mean LOHS was similar in the EUS-GE group compared to SGJ (
P
= 0.35). The rate of recurrent GOO was not different between the two groups (3 % vs. 14 %,
P
= 0.08). Similarly, the mean time to reintervention was similar (88 days vs. 121 days,
P
= 0.83).
Conclusions
EUS-GE is associated with equivalent efficacy and safety as compared to surgical GJ. This is the first comparative trial between both techniques and suggests EUS-GE as a non-inferior but less invasive alter to surgery.
Background and Aims Per-oral endoscopic myotomy (POEM) for achalasia is particularly appealing in the elderly because it is minimally invasive. However, data in patients aged ≥80 years are scarce. ...The aim of this study was to assess the clinical outcome of POEM in octogenarians. Methods This was a multicenter retrospective study at 8 centers. Consecutive octogenarians with achalasia who underwent POEM between 2010 and 2016 were included. Rates of technical success (completion of myotomy), clinical response (Eckardt score ≤3), and adverse events (severity graded as per American Society for Gastrointestinal Endoscopy lexicon) were assessed. Results A total of 76 patients (47.4% female, mean age 84 years) underwent POEM for treatment of achalasia: type I, 17.1%, type II, 35.5%, type III, 17.1%, and unspecified, 30.3%. Overall, 41.1% were treatment-naïve, whereas others had previous botulinum toxin injections and/or pneumatic dilation. The mean (± standard deviation SD) age-adjusted Charlson Comorbidity Index was 6.2 ± 2.4, with the majority of patients having an American Society of Anesthesiologists Physical Status Classification System score of II/III. Technical success was 93.4%, with a median follow-up of 256 days. Fourteen adverse events occurred in 11 patients (14.5%) (3 inadvertent mucosotomies, 6 symptomatic capnoperitoneum/mediastinum, 2 esophageal leaks, 1 cardiac arrhythmia, and 2 other). The severities of these adverse events were 78.6% mild, 14.3% moderate, and 7.1% severe. Clinical success was achieved in 90.8% of patients, with a mean (± SD) Eckardt score reduction from 7.0 ± 2.3 to 0.8 ± 0.1 ( P < .001) (median follow-up 256 days interquartile range 66-547). Conclusions Although the rate of technical success may be somewhat lower and the rate of adverse events slightly higher than previously reported, our data suggest that POEM in octogenarians is safe and effective, supporting its role as a primary modality for achalasia in this patient population.

Background and Aims Endoscopic management of post-Whipple pancreatic adverse events (AEs) with enteroscopy-assisted endoscopic retrograde pancreatography (e-ERP) is associated with high failure ...rates. EUS-guided pancreatic duct drainage (EUS-PDD) has shown promising results; however, no comparative data have been done for these 2 modalities. The goal of this study is to compare EUS-PDD with e-ERP in terms of technical success (PDD through dilation/stent), clinical success (improvement/resolution of pancreatic-type symptoms), and AE rates in patients with post-Whipple anatomy. Methods This is an international multicenter comparative retrospective study at 7 tertiary centers (2 United States, 2 European, 2 Asian, and 1 South American). All consecutive patients who underwent EUS-PDD or e-ERP between January 2010 and August 2015 were included. Results In total, 66 patients (mean age, 57 years; 48% women) and 75 procedures were identified with 40 in EUS-PDD and 35 in e-ERP. Technical success was achieved in 92.5% of procedures in the EUS-PDD group compared with 20% of procedures in the e-ERP group (OR, 49.3; P < .001). Clinical success (per patient) was attained in 87.5% of procedures in the EUS-PDD group compared with 23.1% in the e-ERP group (OR, 23.3; P < .001). AEs occurred more commonly in the EUS-PDD group (35% vs 2.9%, P < .001). However, all AEs were rated as mild or moderate. Procedure time and length of stay were not significantly different between the 2 groups. Conclusions EUS-PDD is superior to e-ERP in post-Whipple anatomy in terms of efficacy with acceptable safety. As such, EUS-PDD should be considered as a potential first-line treatment in post-pancreaticoduodenectomy anatomy when necessary expertise is available.

Prevalence of rectal carcinoids is increasing, partly because of increased colorectal cancer screening. Local excision (endoscopic or transanal excision) is usually performed for small (<1-2 cm) ...rectal carcinoids, but data on clinical outcomes from large population-based U.S. studies are lacking. The aims of this study were to determine the prevalence of metastasis of resected small rectal carcinoid tumors using a large national cancer database and to evaluate the long-term survival of patients after local resection as compared with radical surgery.
The Surveillance Epidemiology and End Results database was used to identify 788 patients with rectal T1 carcinoids <2 cm in size. Prevalence of metastases at initial diagnosis and risk factors for metastases were analyzed. Cancer-specific survival (CSS) was calculated.
A total of 727 patients (92.3%) had tumors ≤10 mm in diameter and 61 (7.7%) had tumors 11 to 19 mm. Overall, 12 patients (1.5%) had metastasis at the time of diagnosis with prevalence of 1.1% in lesions ≤10 mm and 6.6% in lesions 11 to 19 mm (P = .01). Survival of patients with T1 rectal carcinoids without metastasis was significantly better than those with metastasis (5-year CSS of 100% vs 78%, P < .001). Of 559 patients with T1N0M0 rectal carcinoids ≤10 mm, 5-year CSS was 100% in both groups who underwent local excision and those who underwent radical surgery.
Larger T1 rectal carcinoid tumors (11-19 mm) have significantly higher risk of lymph node metastases compared with those ≤10 mm. Survival is worse with metastatic disease. Local therapy is adequate for T1N0M0 rectal carcinoids ≤10 mm in size with excellent long-term outcomes.

Endoscopic retrograde cholangiopancreatography (ERCP) in patients who have undergone Roux-en-Y gastric bypass (RYGB) is technically challenging. We describe our multicenter experience using ...lumen-apposing metal stents (LAMSs) to create an endoscopic ultrasound-guided transgastric fistula (EUS-TG) to facilitate peroral ERCP in these patients.
Thirteen patients with RYGB who underwent EUS-TG at three tertiary centers were included. EUS was used to guide puncture of the excluded stomach from the gastric pouch or jejunum; a LAMS was placed across the transgastric fistula. ERCP was performed via a duodenoscope passed through the LAMS.
The technical success of EUS-TG was 100 % (13/13). ERCP through the LAMS was successful and clinical success was achieved in all patients. LAMS dislodgement during ERCP occurred in two patients and the stent was successfully repositioned without sequelae. After removal of the LAMS, the fistula was closed in 92 % of patients, either by endoscopic closure devices or argon plasma coagulation. None of the patients experienced procedure-related adverse events.
EUS-TG is an effective and safe method of accessing the excluded stomach and performing ERCP in patients with RYGB.
Staple-line leaks occur in 1 % - 7 % of patients who undergo sleeve gastrectomy, and can be challenging to treat. The success of endoscopic approaches decreases as leaks develop into chronic sinus ...tracts. Endoscopic septotomy has been used to facilitate healing of refractory leaks by incision and enlargement of the tract to allow direct communication with the gastric lumen and internal drainage.
We reviewed the technique and outcomes among patients who underwent endoscopic septotomy at two centers for the management of sleeve gastrectomy-associated gastric fistulas and perigastric collections refractory to occlusive endoscopic therapies.
Nine patients underwent endoscopic septotomy at a mean of 8.6 weeks after leak diagnosis, following failure of percutaneous and conventional endoscopic modalities. Perigastric collections ranged from 3 cm to 10 cm in size. The mean procedure time for endoscopic septotomy was 87.2 minutes. Multiple endoscopic septotomy procedures (mean 2.3, range 1 - 4) were required to achieve radiological resolution. The mean follow-up period was 21.2 weeks, and all nine patients achieved symptom resolution without the need for surgery. Bleeding at the time of endoscopic septotomy occurred in three patients, and was managed with endoscopic clips and did not require transfusion. No other adverse events or delayed complications were recorded.
Endoscopic septotomy appears to be a safe and effective technique for the management of sleeve gastrectomy-associated fistulae and collections, including those refractory to other endoscopic and percutaneous methods.
Background and Aims
Spastic esophageal disorders (SEDs) include spastic achalasia (type III), diffuse esophageal spasm (DES), and nutcracker/jackhammer esophagus (JH). Per-oral endoscopic myotomy ...(POEM) has demonstrated efficacy and safety in the treatment of achalasia. Recently, POEM has been indicated for the treatment of SEDs. We conducted a systematic review and meta-analysis to determine the clinical success and safety of POEM in SEDs.
Methods
We searched several databases from 01/01/2007 to 01/10/2016 to identify studies (with five or more patients) on POEM for the treatment of SEDs. Weighted pooled rates (WPRs) for clinical success and adverse events (AEs) were calculated for all SEDs. Clinical success was defined as Eckardt scores of ≤3 and/or improvement in severity of dysphagia based on achalasia disease-specific health-related quality of life questionnaire. The WPRs for clinical success and AEs were analyzed using fixed- or random-effects model based on heterogeneity. The proportionate difference in clinical success and post-procedure adverse event rates among individual types of SEDs was also calculated.
Results
A total of eight observational studies with 179 patients were included in the final analysis. Two studies were of good quality and six were of fair quality based on the National Institutes of Health quality assessment tool. The WPR with 95% confidence interval (CI) for cumulative clinical success of POEM in all SEDs was 87% (78, 93%),
I
2
= 37%. The total number of patients for individual disorders, i.e., type III achalasia, JH, and DES, was 116, 37, and 18, respectively. The WPRs for clinical success of POEM for type III achalasia, DES, and JH were 92, 88, and 72%, respectively. Proportion difference of WPR for clinical success was significantly higher for type III achalasia in comparison with JH (20%,
P
= 0.01). The WPR with 95% CI for AEs of POEM in all SEDs was 14% (9, 20%),
I
2
= 0%. The WPRs for post-procedure adverse events for type III achalasia, DES, and JH were 11, 14, and 16%, respectively. There was no difference in safety of POEM among individual SEDs.
Conclusion
POEM is an effective and safe therapeutic modality for the treatment of spastic esophageal disorders.

Background and Aims Per-oral endoscopic myotomy (POEM) has shown promising safety and efficacy in short-term studies. However, long-term follow-up data are very limited. The aims of this study were ...to assess (1) clinical outcome of patients with a minimum post-POEM follow-up of 2 years and (2) factors associated with long-term clinical failure after POEM. Methods A retrospective chart review was performed that included all consecutive patients with achalasia who underwent POEM with a minimum follow-up of 2 years at 10 tertiary-care centers. Clinical response was defined by a decrease in Eckardt score to 3 or lower. Results A total of 205 patients (45.8% men; mean age, 49 years) were followed for a median of 31 months (interquartile range, 26-38 months). Of these, 81 patients (39.5%) had received previous treatment for achalasia before POEM. Clinical success was achieved in 98% (185/189), 98% (142/144), and 91% (187/205) of patients with follow-up within 6 months, at 12 months, and ≥24 months, respectively. Of 185 patients with clinical response at 6 months, 11 (6%) experienced recurrent symptoms at 2 years. History of previous pneumatic dilation was associated with long-term treatment failure (odds ratio, 3.41; 95% confidence interval, 1.25-9.23). Procedure-related adverse events occurred in 8.2% of patients and only 1 patient required surgical intervention. Abnormal esophageal acid exposure and reflux esophagitis were documented in 37.5% and 18% of patients, respectively. However, these rates are simply a reference number among a very selective group of patients. Conclusions POEM is safe and provides high initial clinical success and excellent long-term outcomes. Among patients with confirmed clinical response within 6 months, 6% had recurrent symptoms by 2 years.
