Perforation of a decubitus gastric ulcer during intragastric balloon retrieval after surreptitious withdrawal of omeprazole.

Male, 24 yo, obesity class 1. We place him a 6 month intragastric balloon. He keeps asymptomatic while taking PPIs, having lost 13 kg in 4 months. He starts on month 5 with epigastric pain, just after abandoning omeprazole on his own. The pain worsens in spite of restarting PPIs and we schedule an urgent retrieval of the balloon. Gastric ulcer perforation occurs during balloon removal and the patient is operated.

Main prophylactic measures in bariatric endoscopy. Spanish Expert Recommendations Guideline.

Bariatric endoscopy (BE) encompasses a number of techniques -some consolidated, some under development- aiming to contribute to the management of obese patients and their associated metabolic diseases as a complement to dietary and lifestyle changes. To date different intragastric balloon models, suture systems, aspiration methods, substance injections and both gastric and duodenal malabsorptive devices have been developed, as well as endoscopic procedures for the revision of bariatric surgery. Their ongoing evolution conditions a gradual increase in the quantity and quality of scientific evidence about their effectiveness and safety. Despite this, scientific evidence remains inadequate to establish strong grades of recommendation allowing a unified perspective on prophylaxis in BE. This dearth of data conditions leads, in daily practice, to frequently extrapolate the measures that are used in bariatric surgery (BS) and/or in general therapeutic endoscopy. In this respect, this special article is intended to reach a consensus on the most common prophylactic measures we should apply in BE. The methodological design of this document was developed while attempting to comply with the following 5 phases: Phase 1: delimitation and scope of objectives, according to the GRADE Clinical Guidelines. Phase 2: setup of the Clinical Guide-developing Group: national experts, members of the Grupo Español de Endoscopia Bariátrica (GETTEMO, SEED), SEPD, and SECO, selecting 2 authors for each section. Phase 3: clinical question form (PICO): patients, intervention, comparison, outcomes. Phase 4: literature assessment and synthesis. Search for evidence and elaboration of recommendations. Based on the Oxford Centre for Evidence-Based Medicine classification, most evidence in this article will correspond to level 5 (expert opinions without explicit critical appraisal) and grade of recommendation C (favorable yet inconclusive recommendation) or D (inconclusive or inconsistent studies). Phase 5: External review by experts. We hope that these basic preventive measures will be of interest for daily practice, and may help prevent medical and/or legal conflicts for the benefit of patients, physicians, and BE in general.

Endoscopic submucosal dissection for gastric epithelial lesions: long-term results in a Spanish cohort.

INTRODUCTION: endoscopic submucosal dissection for gastric lesions (ESD-G) is a technique that allows en-bloc resection of early gastric tumors, with a cure rate similar to that of surgery but lower morbidity and mortality rates. OBJECTIVE: to assess total survival, disease-free survival and relapse rate during the course of disease in a Spanish cohort of patients undergoing ESD-G. MATERIAL AND METHODS: this was a prospective observational study of patients undergoing ESD-G from 2008 to 2015, with a follow-up ranging from six to 60 months. Recurrence at five years was analyzed using Kaplan-Meier curves and the results were compared according to several factors using the log-rank test. These included en-bloc versus piecemeal resection and R0 curative resection versus resection with affected lateral margins (LM+). RESULTS: a total of 35 patients undergoing ESD-G were assessed, with a median follow-up of 33.62 months. Four relapses were identified (11.4%) during this period, of which three were managed with repeat ESD-G. A histological specimen with LM+ was associated with a higher local relapse rate during follow-up (p = 0.06). Piecemeal resections had a higher relapse risk, although no statistically significant differences were identified (p = 0.49). No deaths from gastric cancer occurred and no gastrectomies due to persistent disease were performed during this period. The overall survival rate in our series was 94.3%. CONCLUSIONS: ESD-G in our setting provides high long-term cure rates, while avoiding surgery. These results are similar to those reported by the European series and remain far removed from the cure and relapse rates obtained in Asian cohorts. Local relapse cases may be monitored with endoscopy.

Long-term follow-up after endoscopic submucosal dissection of colorectal lesions in a Spanish cohort.

INTRODUCTION: ESD in the colon is an increasingly important technique in Western countries. There are few studies that include long term follow-up. AIM: to analyze the long term recurrence free survival rate after ESD and to compare recurrence rates according to different variables. METHODS: this was a prospective observational study of patients with a planned ESD from September 2008 to December 2015. When it was not possible to achieve an ESD, hybrid ESD was performed, either en bloc or piecemeal. Kaplan-Meier survival curves were used to assess the five year local recurrence free survival rate and the recurrence rate. The results were compared according to different factors. RESULTS: of the 89 patients scheduled for ESD who were initially enrolled in the study, 69 were finally included for follow-up. ESD was performed in 31 (45%) patients, KAR in eleven (16%) and pKAR in 27 (39%). The median follow-up was 27 months (range 6-60). The five year disease free survival rate was 81%. The average number of endoscopies needed to eliminate recurrence was two (range 2-7) and no patient required surgery for this reason. The recurrence rate was significantly higher in piecemeal resections vs en bloc resections (27% vs 15%, p = 0.036) and R1 resections vs R0 resections (26% vs 0%, p = 0.034). The presence of affected or unknown lateral margins in en bloc resections without other poor prognosis factors had higher recurrence rates but the difference was not statistically significant (28% vs 0%, p = 0.09). CONCLUSIONS: in our study, the five year disease free survival rate was 81% and no patient required surgery during follow-up. Piecemeal and R1 resections had significantly higher recurrence rates, as well as LM involvement, although this was not statistically significant.

Complete resolution of dysphagia after sequential Polyflex™ stenting in a case of recurrent anastomotic stenosis in an adult with congenital esophageal atresia.

We present a case of intractable dysphagia in a 23-year-old female with type 1 esophageal atresia (EA) and subsequent postsurgical refractory esophageal strictures. The patient was referred due to increasing symptomatology and a slight response to balloon dilations. A biodegradable polydioxanone stent (ELLA) was placed, but this did not relieve the dysphagia. After the sequential placement of two siliconated polypropylene stents (Polyflex™, Boston Scientifics), the dysphagia was definitively relieved. To our knowledge, this is the first published case with a full resolution of dysphagia using this strategy in an adult patient.
