Abstract Background and study aims Adenoma recurrence is one of the key limitations of endoscopic mucosal resection (EMR), which occurs in 15 % to 30 % of cases during first surveillance colonoscopy. The main hypothesis behind adenoma recurrence is leftover micro-adenomas at the margins of post-EMR defects. In this systematic review and meta-analysis, we evaluated the efficacy of snare tip soft coagulation (STSC) at the margins of mucosal defects to reduce adenoma recurrence and bleeding complications. Methods Electronic databases such as PubMed and the Cochrane library were used for systematic literature search. Studies with polyps only resected by piecemeal EMR and active treatment: with STSC, comparator: non-STSC were included. A random effects model was used to calculate the summary of risk ratio and 95 % confidence intervals. The main outcome of the study was to compare the effect of STSC versus non-STSC with respect to adenoma recurrence at first surveillance colonoscopy after thermal ablation of post-EMR defects. Results Five studies were included in the systematic review and meta-analysis. The total number patients who completed first surveillance colonoscopy (SC1) in the STSC group was 534 and in the non-STSC group was 514. The pooled adenoma recurrence rate was 6 % (37 of 534 cases) in the STSC arm and 22 % (115 of 514 cases) in the non-STSC arm, (odds ratio [OR] 0.26, 95 % confidence interval [CI], 0.16–0.41, P = 0.001). The pooled delayed post-EMR bleeding rate 19 % (67 of 343) in the STSC arm and 22 % (78 of 341) in the non-STSC arm (OR 0.82, 95 %CI, 0.57–1.18). Conclusions Thermal ablation of post-EMR defects significantly reduces adenoma recurrence at first surveillance colonoscopy.

The NCCN Guidelines for Squamous Cell Skin Cancer provide recommendations for diagnostic workup, clinical stage, and treatment options for patients with cutaneous squamous cell carcinoma. The NCCN panel meets annually to discuss updates to the guidelines based on comments from panel members and the Institutional Review, as well as submissions from within NCCN and external organizations. These NCCN Guidelines Insights focus on the introduction of a new surgical recommendation terminology (peripheral and deep en face margin assessment), as well as recent updates on topical prophylaxis, immunotherapy for regional and metastatic disease, and radiation therapy.

BACKGROUND: The diagnosis of isolated small bowel Crohn’s disease (CD) can be challenging. Symptoms are non-specific and both imaging and capsule endoscopy (CE) may be misleading as several diseases may mimic CD. Double balloon enteroscopy (DBE) allows a more extensive endoscopic and histologic evaluation of the small bowel. Our aim was to describe the diagnostic utility and impact of DBE on management of patients with known CD and in patients with suspected/rule-out CD. METHODS: Retrospective review of our institution’s DBE database from February 2009 to May 2013. Adult patients referred for DBE for further evaluation of known or suspected CD (due to symptoms, abnormal imaging and/or CE) were included. Patient demographics, clinical characteristics, imaging and CE results, prior DBE, indication for DBE, DBE findings, DBE adverse events, pathology findings, final diagnosis, treatment prior and post DBE and follow-up DBE were abstracted from the electronic medical record. RESULTS: A total of 108 patients were included, 61 (56%) females, mean age 52 years (range 20-83). Indications for DBE included: disease activity assessment/therapeutic in 10 patients with established diagnosis of CD and for diagnostic purposes in 98 patients with suspected CD (31 patients due to abnormal imaging, 29 due to abnormal CE and 26 due to both abnormal imaging and CE). Upper, lower, bidirectional upper and lower, and stomal DBE were performed in 21, 24, 62 and 1 patients, respectively. DBE revealed active disease in 8/10 patients with known CD with one patient undergoing dilation of a stricture. Changes in management were recommended for all patients with active disease – start thiopurine (2), optimize thiopurine dose (1), start biologics (3) change biologics (1), systemic steroids (1) and budesonide (1). The patient who underwent stricture dilation ultimately required surgery. A definitive diagnosis of CD (both endoscopic and histologic) was reached in only 39/98 (40%) patients who were referred for suspected CD. Changes in management were recommended in 32/39 (82%) patients. Interestingly, 24/98 patients had been diagnosed with CD at outside institutions and were recommended to initiate therapy for CD. Of these, CD was confirmed in only 15/24 (63%) patients. Adverse events included perforation in 1 patient (1%) who required surgical management and mouth swelling/abrasion in 3 patients (3%). Follow-up DBE to re-assess disease activity was performed in 10/49 (20%) patients with definitive diagnosis of CD, average time between procedures 4.5 years (range 0.7-11.6). One patient with CD was diagnosed with lymphoma 2.4 years after initial DBE. Changes in management were recommended in 6 patients: de-escalation of therapy (3, two underwent surgery), start thiopurine and/or biologic (2) and switch biologics (1). No complications were seen at follow-up DBE. CONCLUSION: DBE is a useful technique to confirm a diagnosis in patients who have suspected CD and can help establish a diagnosis of several diseases that may mimic CD on CT scan or CE. Additionally, DBE in patients with established diagnosis of small bowel CD is an effective tool to assess disease activity and guide therapy. Serious complications are infrequent.

Objective The medical management of gastroesophageal reflux disease (GERD) continues to evolve. Our aim was to systematically assess the literature to provide an updated review of the evidence on lifestyle modifications and pharmacological therapy for the management of GERD. Background The cornerstones of GERD medical management consist of lifestyle modifications and pharmacologic agents. Most recently, evidence has emerged linking anti-reflux pharmacologic therapy to adverse events, such as kidney injury, metabolic bone disease, myocardial infarction, and even dementia, among others. Methods A systematic search of the databases of PubMed/MEDLINE, Embase, and Cochrane Library was performed for articles on the medical management of GERD between inception and March 1, 2021. Conclusion Although pharmacological therapy has been associated with potential adverse events, further research is needed to determine if this association exists. For this reason, lifestyle modifications should be considered first-line, while pharmacologic therapy can be considered in patients in whom lifestyle modifications have proven to be ineffective in controlling their symptoms or cannot institute them. Naturally, extra-esophageal causes for GERD-like symptoms must be considered on suspected high-risk patients and excluded before considering treatment for GERD.

Abstract Background and study aims Anticoagulation (AC) and antiplatelet (AP) therapy may increase the risk of gastrointestinal bleeding after double balloon enteroscopy (DBE); however, limited data are currently available regarding the incidence. The aim of this study was to assess the incidence and clinical characteristics of post-DBE bleeding in patients on AC and AP therapy. Patients and methods The medical records of patients who underwent DBE between 2009 and 2013 at Mayo Clinic, Florida, were retrospectively reviewed. Patients were divided into three groups: 1) continued AP therapy; 2) AC therapy; and 3) neither AP nor AC at the time of DBE. Follow-up data were collected at 60 days and 1 year. Results A total of 683 patients were identified; 43 on AC, 183 on AP and 457 not on AP or AC therapy. The most common indication for DBE was obscure gastrointestinal bleeding in the groups on and not on AP (85.3 % vs 70.9 %, P < 0.0001). There was no statistical difference in post-DBE bleeding rates in patients on AP vs not on AP at 60 days (11.5 % vs 7.5 %, P = 0.12) or 1 year (19.9 % vs 15.7 %, P = 0.23). Rates of bleeding in patients on AC were 11.6 % within 60 days and 22.5 % within 1 year. Multivariate analysis reflected American Society of Anesthesiologist > 3 and indication for DBE of GI bleeding were independent risk factors for post-DBE bleeding within 1 year. Conclusions Continued antiplatelet use at the time of DBE was not an independent risk factor for bleeding post-DBE at 60 days or 1 year of follow up.

ABSTRACT Insulinomas are rare, with an annual incidence of 1–4 people per mission. Insulinomas are the most common functioning endocrine neoplams of the pancreas. Endoscopic ultrasound has both diagnostic and therapeutic yield in undifferentiated pancreatic tumors. We present a case of a recurrent insulinoma, refractory to surgical and medical management diagnosed with endoscopic ultrasound. Our case uniquely conveys a successful, alternative approach to addressing symptomatic insulinomas refractory to surgical or medical management through computed tomography–guided percutaneous ethanol-lipiodol injection.
