The Slender Esophagus: Unrecognized Esophageal Narrowing in Eosinophilic Esophagitis.

INTRODUCTION: Inflammation in eosinophilic esophagitis (EoE) often leads to esophageal strictures. Evaluating esophageal narrowing is clinically challenging. We evaluated esophageal distensibility as related to disease activity, fibrosis, and dysphagia. METHODS: Adult patients with and without EoE underwent endoscopy and distensibility measurements. Histology, distensibility, and symptoms were analyzed. RESULTS: Patients with EoE had significantly lower distensibilities than controls. We found a cohort with esophageal diameter under 15 mm despite lack of dysphagia. DISCUSSION: This study raises concern that current assessments of fibrostenosis are suboptimal. We describe a cohort with unrecognized slender esophagus that were identified through impedance planimetry measurements. This tool provides additional information beyond symptomatic, histologic, and endoscopic assessments.

Gastric Neuroendocrine Tumors (Carcinoids).

PURPOSE OF REVIEW: The diagnosis of gastric neuroendocrine tumors (NETs) is being made with increased frequency likely as a result of more upper endoscopies being done for unrelated reasons. It is therefore vital that gastroenterologists become familiar with the basic work-up and management of patients found to have these tumors. This review describes the classification, pathophysiology, clinical characteristics, and treatment options of the different gastric NETs. RECENT FINDINGS: In addition to the three traditional subtypes of gastric NETs, additional cases associated with achlorhydria and appropriate hypergastrinemia may exist. The management of gastric NETs between 1 and 2 cm in size remains controversial and needs to be individualized. Gastric NETs are uncommon but are now diagnosed more frequently. This review highlights the role of hypergastrinemia in their development and the controversies around their management.

Initial experience with a novel resection and plication (RAP) method for acid reflux: a pilot study.

BACKGROUND AND STUDY AIMS: Current endoscopic therapies for gastroesophageal reflux disorder (GERD) are limited by technical complexity, and/or cost. We sought to evaluate the success of a novel resection and plication (RAP) anti-reflux procedure. PATIENTS AND METHODS: RAP was performed on 10 patients with GERD refractory to proton pump inhibitor (PPI) therapy. RAP consists of semi-circumferential mucosectomy along with full-thickness plication of the lower esophageal sphincter (LES) and cardia. We assessed the technical success and safety as well as followed GERD-Health Related Quality of Life (GERD-HRQL) scores and medication usage. RESULTS: All patients underwent RAP without adverse events and were discharged on the same day. Only half of the patients required general anesthesia. Follow-up ranged from 5 to 24 months (median 9 months) and all patients had a significant improvement in their GERD-HRQL scores ( P  < 0.0001, 95 % CI 19.3 - 25.3). 8 of 10 eliminated their daily PPI dependence. CONCLUSIONS: The RAP method has potential as an effective anti-reflux option. Its main advantages include a short procedure time, simple approach using readily available equipment, and possible avoidance of general anesthesia.
