Perforated duodenal ulcer after laparoscopic Gastric Bypass.
Obesity surgery, 2008Co-Authors: B. Gypen, Guy Hubens, Vera Hartman, L. Balliu, Thiery Chapelle, W. VaneerdewegAbstract:A patient with a history of a laparoscopic Gastric Bypass presented with a perforated duodenal ulcer. The ulcer was laparoscopically oversewn, and an omentoplasty was performed. Postoperatively, a broad spectrum antibiotic and a proton pump inhibitor were administrated. Several questions arise regarding the diagnosis and treatment of duodenal ulcers after Gastric Bypass. What are the diagnostic tools to detect a duodenal ulcer, and how should Helicobacter pylori be diagnosed after Gastric Bypass? The key question is whether the Bypassed stomach should be resected as a definitive treatment for complicated duodenal ulcers.

Use and outcomes of laparoscopic versus open Gastric Bypass at academic medical centers.
Journal of the American College of Surgeons, 2007Co-Authors: Ninh T Nguyen, Marcelo W. Hinojosa, Christine Fayad, Esteban Varela, Samuel E WilsonAbstract:Background A large outcome study of laparoscopic Gastric Bypass has not been done because of difficulty in differentiating between open and laparoscopic procedures in the absence of a specific ICD-9 procedural code for the laparoscopic operation. The University HealthSystem Consortium (UHC) clinical database recently added a specific procedural code for laparoscopic Gastric Bypass. The goal of this study was to compare the use and outcomes of laparoscopic versus open Gastric Bypass at academic centers. Study Design Using ICD-9 diagnosis and procedure codes, we obtained data from the UHC clinical database for all patients who underwent laparoscopic or open Roux-en-Y Gastric Bypass for treatment of morbid obesity between 2004 and 2006 (n = 22,422). The main outcomes measures were demographics, comorbidities, length of hospital stay, 30-day readmission, morbidity, observed and expected (risk-adjusted) mortality, and costs. Results There were 16,357 patients who underwent laparoscopic Gastric Bypass and 6,065 patients who underwent open Gastric Bypass. Laparoscopic Gastric Bypass patients had a shorter length of hospital stay (2.7 days versus 4.0 days, p Conclusions This nationwide analysis of academic medical centers between 2004 and 2006 showed that bariatric surgery has shifted to a predominately laparoscopic approach. In addition, laparoscopic Gastric Bypass is as safe as open Gastric Bypass and is considerably associated with a lower 30-day morbidity.

Gastrointestinal hemorrhage after laparoscopic Gastric Bypass.
Obesity surgery, 2004Co-Authors: Ninh T Nguyen, Mario Longoria, Sara Chalifoux, Samuel E WilsonAbstract:Gastrointestinal hemorrhage is a potential perioperative complication after Roux-en-Y Gastric Bypass. The surgeon performing laparoscopic Gastric Bypass should understand the need for early recognition and management of this complication, as it can be life-threatening. This paper discusses the incidence and clinical presentation of gastrointestinal hemorrhage, mechanisms for hemorrhage, management options, and possible methods of prevention.

Laparoscopic Versus Open Gastric Bypass
Seminars in laparoscopic surgery, 2002Co-Authors: Ninh T Nguyen, Bruce M. WolfeAbstract:Laparoscopic Bypass has become a common approach for the treatment of morbid obesity. This article compares the results of laparoscopic Gastric Bypass with that of open Gastric Bypass based on published data from prospective series, comparative studies, and randomized clinical trials.

Current status of laparoscopic Gastric Bypass.
Minerva chirurgica, 2002Co-Authors: Ninh T Nguyen, Bruce M. WolfeAbstract:Laparoscopic Gastric Bypass is emerging as a commonly performed procedure for the treatment of morbid obesity.

Laparoscopic Roux-en-Y Gastric Bypass for morbid obesity.
JSLS : Journal of the Society of Laparoendoscopic Surgeons, 1999Co-Authors: Ninh T Nguyen, Kathrin L. Mayer, Levi S Palmer, Bruce M. WolfeAbstract:Surgery is currently the only effective treatment for morbid obesity. The two most commonly accepted operations are the Roux-en-Y Gastric Bypass and vertical banded gastroplasty. Although multiple authors have reported on a laparoscopic approach to Gastric banding, the Roux-en-Y Gastric Bypass is a complex operation to be replicated using laparoscopic techniques. In this article, we describe our technique of the Roux-en-Y Gastric Bypass using a laparoscopic approach in four cases.
