Surgery Vs. No Surgery: a Controlled Study of Outcomes Following Bariatric Surgery
Introduction:Bariatric surgery has been shown to be an effective therapy that results in long term weight loss, resolution of co-morbidities and improved quality of life (QOL). Most of these studies lack comparison with a non-operative group. We hypothesize that after one year, patients who undergo bariatric surgery will see significant weight loss, resolution of co-morbidities… Continue Reading

Survival Study of NOTES Rectosigmoid Resection Using Transanal Endoscopic Microsurgery (tem) with or Without Transgastric Endoscopic Assistance in a Swine Model
INTRODUCTION: Our group has previously demonstrated the feasibility of NOTES rectosigmoid resection in a swine cadaver model using TEM alone or in combination with transgastric endoscopic assistance to extend the length of colon mobilization. METHODS: A survival study of transanal endoscopic rectosigmoid resection with stapled coloanal anastomosis was conducted in swine using TEM (n=8) and… Continue Reading

Suture Line Buttresses Are Not Associated with Fewer Complications in Roux-en-Y Gastric Bypass
Introduction Suture line complications can cause major morbidities and mortality after Roux-en-Y gastric bypass. Suture line buttresses have been used in an attempt to prevent these complications. This study was done to determine if the introduction of suture line buttressing to our practice has decreased our complication rate.Methods After obtaining IRB approval, our database was… Continue Reading

Teaching Laparoscopic Cholecystectomy in Developing Countries – a Safe, Cost Effect, and Time-efficient Model
Introduction: We present a laparoscopic training program for the developing world that emphasizes safety and sustainability, which has been successfully implemented in two countries. This is to counter significant barriers to the adoption of laparoscopic cholecystectomy, including the local infrastructure, the high cost of laparoscopic equipment, lack of skilled preceptors, and concerns regarding the safety… Continue Reading

Technique and Outcomes for Patients Requiring Laparoscopic Surgery After Large Ventral Hernia Repairs
OBJECTIVE: Patients with ventral hernia repairs risk mesh infection with subsequent surgeries, which can lead to serious morbidity. Such patients need an unorthodox approach to prevent serious complications such as mesh infection or recurrent hernias. METHODS: Patients who had large ventral hernia repairs and subsequently underwent laparoscopic procedures for various purposes were retrospectively reviewed. The… Continue Reading

Technique for Laparoscopic-Assisted Formal Right Hepatectomy, Deconstructed
BACKGROUND: Laparoscopic formal right hepatectomy remains a technical challenge. We propose that the procedure can be accomplished efficiently with standard laparoscopic techniques, in ordered sequence, using smaller incisions, and having identical outcomes as the open procedure. METHOD: We reviewed 25 consecutive video recordings of formal laparoscopic right hepatectomy performed over a 4 month period. Instruments… Continue Reading
Tele-mentoring for Advanced Endoscopic Surgery Using Soft Cadavers Between Thailand and Japan
BACKGROUND: Endoscopic surgery has developed dramatically during the past decade because of its several advantages. Endoscopic surgery requires new unique skills that differ from those in open surgery, and therefore, a professional education / training is very important. However, since there is not necessarily an excellent instructor anywhere, the difference of surgical skill level between… Continue Reading

Telegrading of Technical Skills Portion of Fundamentals of Laparoscopic Surgery
Introduction: Fundamentals of Laparoscopic Surgery (FLS) is considered a validated educational module for basic laparoscopy. Recently, FLS and its testing have become available at no cost for all general surgery residency programs. Unfortunately, there are a relatively limited number of testing sites. This investigation studied the hypothesis that the technical skills portion of FLS test… Continue Reading

Telesimulation in Africa: An Effective Method for Teaching the Fundamentals of Laparoscopic Surgery in Developing Countries
Introduction: Several challenges exist with laparoscopic skills training in developing countries including long travel distances required by mentors for onsite teaching. Telesimulation (TS) is a novel concept that uses the internet to link simulators between an instructor and trainee in different locations. The purpose of this study was to determine the effectiveness of telesimulation for… Continue Reading

Temporary Mucocutaneous Transverse Colostomy: Technical Approach.
INTRODUCTION: Transverse colostomy (TC) is a surgical procedure used to protect a low colorectal or coloanal anastomosis. The aim of this study was to evaluate the risks and benefits of a temporary mucocutaneous TC.METHODS: 83 patients (56 males, 27 females) with TC were retrospectively reviewed. The indications for fecal diversion included colorectal carcinoma (27) 32.5%,… Continue Reading

Tep Repair of a Bilateral Obturator Hernia
Introduction: Obturator hernias (OH) are rare and difficult to diagnose. While they account for as few as 0.073% of all hernias, their mortality can be as high as 70%. OH affects women more commonly than men (ratio ~8:1). Other risk factors are emaciation, multiparity, and chronic conditions that increase the intra-abdominal pressure such as COPD… Continue Reading

Test Method for Evaluation of Blood Loss and Free Bleed Time
Objective: To develop a quantitative in vivo test method for measuring acute blood loss and time to hemostasis in order to assess the hemostatic performance of investigational linear stapling and dividing devices. Methods: All animals were screened pre-operatively for clotting sufficiency. Pertinent vital parameters were also controlled within narrow limits during testing (MAP = 80… Continue Reading

Testing Construct Validity for a Virtual Reality Colonoscopy Simulator: Module Matters
Background: The use of simulation for competency assessment requires validation of the simulation’s performance metrics. This study was designed to assess whether the Simbionix GI Mentor II® virtual reality simulator metrics could differentiate endoscopists with varying clinical experience using modules of increasing clinical complexity (known-groups construct validity). Methods: 20 subjects were classified into two groups… Continue Reading

The Combined Laparoscopic Approach to Incarcerated Inguinal Hernia
Background: The laparoscopic preperitoneal repair of inguinal hernias is an accepted and widely used approach, and several reports have demonstrated its advantages over an open repair. Incarcerated hernia is still considered an indication for an open repair, for several reasons, including the technical complexity, availability of trained laparoscopic surgeon for an emergent procedure, and the… Continue Reading
