Introduction: Achalasia can be complicated by a distal esophageal pulsion diverticulum. This study was undertaken to determine outcomes after Heller myotomy, anterior fundoplication, and diverticulectomy.
Methods: 617 patients undergoing laparoscopic Heller myotomy and anterior fundoplication 1992-2014 are prospectively followed; patients were sorted for those undergoing concomitant diverticulectomy. Patients graded symptom frequency/severity before/after myotomy using a Likert scale (0= neve
Introduction
Gastroparesis is a syndrome characterized by nausea, vomiting, bloating, and abdominal pain in the setting of delayed gastric emptying. Dietary modifications and various medical therapies of gastroparesis are rarely effective. Surgical options for delayed gastric emptying include gastric stimulator implantation, feeding jejunostomy or venting gastrostomy, subtotal gastrectomy, and pyloroplasty. Pyloroplasty has long been shown to improve gastric emptying yet is seldom described as
Background
Operations of complex hiatal hernias, paraesophageal hernias (PEHs) or large recurrent hiatal hernias, have a better chance of success when a tension-free closure of the hiatus can be done. Because in many of these patients the closure involves tension or inability to close, reinforcement with mesh has been recommended. A relaxing incision in the diaphragmatic crus may help accomplish a tension free closure. This study evaluates the use of crural relaxing incisions and biologic me
Introduction: The Fundamental Use of Surgical Energy (FUSE) program includes a web-based didactic curriculum and a high-stakes multiple choice question examination with the goal to provide certification of knowledge on the safe use of surgical energy-based devices. The purpose of this study was (1) to set a passing score through a psychometrically sound process, and (2) to determine what pre-test factors predicted passing the FUSE examination.
Methods: Beta-testing of multiple choice questions
Background:
Lymph node metastasis occurs in approximate 10% of early gastric cancer. Pre-operative or intra-operative identification of lymph node metastasis in early gastric cancer is crucial for surgical planning. The purpose of this study was to evaluate the feasibility of using carbon nanoparticles to show sentinel lymph nodes (SLNs) in early gastric cancer.
Methods:
A multi-center study was performed between July 2012 and July 2014. Ninety one patients with early gastric cancer identifie
