Outcomes of Laparoscopic Ventral Hernia Repair
INTRODUCTION: The high recurrence rate of conventional open repair in the treatment of ventral hernias has caused a paradigm shift in its treatment to the laparoscopic approach. MATERIALS & METHODS: Our single centre series involves a retrospective review of 80 consecutive patients who underwent laparoscopic ventral hernia repair (LVHR) from 2001 to 2006. RESULTS: The… Continue Reading

Outcomes of Non-surgical Management of Gallbladder Disease during Pregnancy: A Single Center Experience
Background:The indications for non-emergent operations during pregnancy remain undefined. Many surgeons defer non-emergent operations until after delivery to minimize fetal risk. We wished to determine the outcome of delaying cholecystectomy in pregnant patients hospitalized for non-acute gallbladder disease.Methods:After approval from the Institutional Review Board, a retrospective case review was performed at a large volume regional… Continue Reading

Overview on Endolumenal Therapy and N.o.t.e.s. in Obesity and Metabolic Disease Treatment. What Will Be the Future?
Background: Intragastric balloon has been used in obese patients as a restrictive gastric procedure inducing early satiety and weight loss. This prospective study assesses both the safety and effectiveness of intragastric Balloon (BIB®) in the treatment of obese patients. Endoscopic Sleeve Gastroplasty was showed at SAGES Las Vegas Meeting by Roberto Fogel (apr/07). Endoscopic Duodenum-Jejunum… Continue Reading

Parastomal Hernia: A Modification of a Laparoscopic Technique
Background: Parastomal hernia is a common complication of stoma formation that has been reported in more than 50% of patients on long-term follow up. Multiple techniques have been described, but there is an absence of a consensus on the most advantageous method to repair parastomal hernia.We propose a modification of a laparoscopic technique, which combines… Continue Reading

Patient factors predictive of 24 hour pH normalization following endoluminal gastroplication for GERD
Background: Endoluminal full thickness gastroplication has been shown to have significant and long lasting improvement of GERD symptoms and health related quality of life (HRQL) with very little patient morbidity. These treatments, however, are criticized for normalizing esophageal acid exposure in only 30 – 40% of patients treated. We hypothesize that there are objective criteria… Continue Reading

Pattern of early esophageal adenocarcinoma in Long Segment Barrett\’s esophagus
Introduction:The purpose of Barrett’s surveillance programs is to assess the precursor lesion for the development of invasive adenocarcinoma and detect cancer as early as possible. Previous studies have demonstrated that the length of Barrett’s esophagus is an independent risk factor for the development of esophageal adenocarcinoma and that cancer is typically located at the distal… Continue Reading

Percutaneous Endoscopic Gastrostomy in Patients on Antiplatelet Therapy: Are Bleeding Complications Increased?
Percutaneous Endoscopic Gastrostomy (PEG) is a commonly performed procedure amongst hospitalized patients. Patients requiring PEG are frequently treated with antiplatelet agents for chronic conditions. Guidelines of the American Society of Gastrointestinal Endoscopy published in 2006 recommend that practitioners consider discontinuing antiplatelet agents for 7-10 days prior to PEG placement. Discontinuing antiplatelet agents for one week… Continue Reading

Percutaneous Roux Limb Jejunostomy: An Alternative Approach to Enteral Access in Gastric Bypass Patients
INTRODUCTIONSevere nausea and vomiting, recurrent dehydration, and malnutrition occur infrequently after gastric bypass. A small number of patients, though, will present with refractory symptoms requiring multiple hospitalizations and intravenous or enteral nutrition. Enteral access routes have previously included either a nasojejunal feeding tube or gastrostomy tube placement in the gastric remnant. We present our experience… Continue Reading

Perforated Marginal Ulcers after Laparoscopic Gastric Bypass
Introduction: A perforated marginal ulcer (PMU) following laparoscopic Roux-en-y gastric bypass (LRYGB) is a potentially serious complication, but the incidence and etiology has rarely been investigated. We therefore performed a retrospective review of all patients undergoing LRYGB at our center to determine our incidence of perforated marginal ulcer and if any causative factors could be… Continue Reading

Performance Measures of Surgeon-endoscopists in a Veterans Affairs Medical Center: Appropriateness of Surgical Resident Colonoscopy Training
Objective: Colonoscopy training is recognized to be important for surgical resident training. This study aimed to determine if surgeon-endoscopists meet quality indicators in the performance of colonoscopy in a Veteran's Medical Center.Methods: Retrospective review of prospective standardized computer endoscopic reporting database (ProVationMDR). All colonoscopies performed by two attending surgeons (one general and one colorectal) between… Continue Reading
Peritonitis from PEG tube insertion and ensuing complications in Surgical ICU patients: Identification of risk factors and clinical outcome
OBJECTIVE - Percutaneous Endoscopic Gastrostomy (PEG) tubes are routinely placed in Surgical Intensive Care Unit (SICU). Poor tissue healing or technical issues after tube insertion can lead to peritonitis requiring a laparotomy. Risk factors leading to this major complication are not identified.METHODS - We conducted a retrospective review of all PEG tubes inserted in SICU… Continue Reading

Polypropylene mesh (PPM) or Light weight mesh (LWM) in inguinal hernia surgery (TEP)- results of a prospective randomized controlled study
Objectives of study-Mesh application in endoscopic hernia surgery is universal. Textile, weight and pore size of mesh continue to be debated. LWMs with larger pores seem to address the concerns of host response. Aim of this study was to evaluate the advantages if any of LWMs over PPMs in totally extraperitoneal (TEP) repair of inguinal… Continue Reading

Portal venous gas one year after laparoscopic Roux-en-Y gastric bypass. a case report of a unique pathology.
Introduction: Hepatic portal venous gas is a radiographic finding typically associated with bowel ischemia, and is considered to be a poor prognostic sign prompting urgent operative exploration. Portal venous gas frequently occurs after instrumentation of the biliary tree, and may also be seen after insufflation of the abdomen for laparoscopy. In addition, portal venous gas… Continue Reading

Potential Molecular Pathways involving the Resolution of Type II Diabetes following RYGB
Background: Following Roux-en-Y gastric bypass (RYGB), hyperglycemia dramatically improves in obese patients with Type II diabetes (T2D). For many patients, hypoglycemic agents and insulin are discontinued after RYGB. However, the exact mechanisms of this process are unknown. This unique study attempts to identify differences in gene expression profiles between pre- and post-operative T2D patients following… Continue Reading
