High Visceral Adipose Volume Impairs Beta-cell Function and May Influence Surgical Options
BACKGROUND: The mechanism for type-2 diabetes (T2DM) resolution following bariatric surgery is unknown, but is typically more robust for malabsorptive procedures (roux-en-Y gastric bypass, RYGB) than for restrictive procedures (laparoscopic gastric banding, LGB). We hypothesize that high visceral volume is a predictor of pre- or frank diabetes and surgeries that rapidly deplete visceral adipose stores… Continue Reading

Hospital Colectomy Volume As a Surrogate for Advanced Laparoscopy
Although laparoscopic colectomy has been reported to have favorable outcomes compared to open colectomy, it has yet to gain widespread acceptance in the United States. We sought to investigate whether hospital volume for colectomy was an important factor to predict the likelihood of having colectomy performed laparoscopically.Methods: Using the Nationwide Inpatient Sample (NIS) from 1998… Continue Reading

Hospital Experience, Body Image, and Cosmesis After Laparoscopic or Open Splenectomy
Introduction: We aimed to assess the hospital experience and body image - cosmesis after laparoscopic or open conventional splenectomy.Methods and procedures: Patients who underwent splenectomy were invited to fill out the questionnaires evaluating hospital experience, body image and cosmetic results. Student’s t-test, paired samples t-test and ki-square test were used for statistical analaysis.Results: A total… Continue Reading

How Do Nurses and Physicians Learn Gastrointestinal Endoscopy: Assessment of Learning Curves Using a High-fidelity Virtual Reality Simulator
Background:Recently, it has been suggested that nurses can perform diagnostic endoscopic procedures, which traditionally have been a physician’s responsibility. The existing studies concerning quality of sigmoidoscopy performed by nurses are small, used assessment tools with insufficient validation and to date there is very little knowledge of the learning curve patterns for physicians and nurses. The… Continue Reading

How to Improve the Quality of Endoscopic Surgical Skill Qualification in Japan in the Section of Laparoscopic Cholecystectomy
The Japan Society for Endoscopic Surgery (JSES) started Endoscopic Surgical Skill Qualification (ESSQS) in 2004, and carried out four examinations up to 2007. Assessment was performed by reviewing documents, laparoscopic surgery experiences, and qualifying unedited video tape by two independent referees. We adopted two criteria to evaluate surgical skills, as common and procedure-specific criteria to… Continue Reading

Human Gallbladder Measurements and Implications for Natural Orifice Surgery
Background: Natural orifice translumenal endoscopic surgery (NOTES) introduces a paradigm shift in minimally invasive surgery that may benefit patients with decreased post-operative pain, faster recovery, better cosmesis, and less surgical morbidity by reducing abdominal incisions. While several NOTES and hybrid-NOTES cholecystectomies have been performed throughout the world, much research is needed to refine the technique,… Continue Reading

Human Monocyte Activation By Biologic and Biodegradable Meshes in Vitro
INTRODUCTION: We hypothesize that various biologic and biodegradable meshes (BM) differentially induce macrophage (MØ) activation in vitro. Inflammation and wound healing play critical roles in the integration of biologic and biodegradable meshes (BM) at the sites of hernia repair. Macrophages (MØ) are the key cells controlling inflammation and wound healing. Interleukin-1beta (IL-1b), IL-6, and IL-8… Continue Reading

Hybrid NOTES Cholecystectomy: Prospective Human Series
Introduction. Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. It is not yet possible at the present time to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids, a fusion of minilaparoscopy… Continue Reading

Hybrid Transvaginal NOTES Sleeve Gastrectomy in a Pocine Model Using a Magnetically Anchored Camera and Novel Instrumentation
Introduction: The purpose of this study was to determine the feasibility of transvaginal NOTES sleeve gastrectomy using novel instrumentation in a porcine model.Methods: Anesthetized pigs (non-survival (n=7), 14-day survival (n=1)) underwent sleeve gastrectomy procedures. Under endoscopic visualization, a 25mm x 40cm access port was inserted through a vaginotomy into the peritoneal cavity using blunt dissection… Continue Reading

Ileostomy Reversal After Left Colonic or Rectal Resection for Cancer: Does the Initial Approach (laparoscopy Versus Laparotomy) Affect Outcome?
The aim of stoma in patients who had left colonic or rectal resection for cancer is to limit the consequences of anastomotic leakage. We retrospectively analyzed the short-term outcome of patients who had ileostomy reversal in this setting. Patients who had initial laparoscopic cancer resection were compared to those who had the same procedure openly.The… Continue Reading

Image Overlay Navigation By Fluctuation Adjusting Accelerometer in Laparoscopic Surgery and NOTES
Purpose:Manipulating instruments inside the human body during laparoscopic surgery and NOTES translumenal surgery can be very difficult for even well experienced surgeons due to the loss of 3D depth perception. Classical navigation techniques are often incapable of providing support in such situations, as the augmentation of the scene with the necessary artificial markers is usually… Continue Reading

Immediate Outcome Afte 350 Laparoscopic Splenectomies (ls). A Single Team 15 Years Experience
Laparoscopy has become the gold standard approach for LS. It relative infrequency impairs the obtention of definitive or evidence based data. LS outcome would differ according the hematological diagnosis, and the size of the spleen is considered a critical factor related to the outcome. Aim: To asses the impact of primary diagnosis (benign/malignant) or spleen… Continue Reading

Impact of Advanced Laparoscopy Courses on Present Surgical Practice
Introduction: The introduction of new techniques makes training in advanced laparoscopic procedures a necessity for the practicing surgeon but acquisition of new surgical skills is a daunting task. SAGES has defined guidelines for training and practice of laparoscopic procedures. Recently introduced laparoscopic techniques have created a new teaching paradigm focused on animate courses and preceptor… Continue Reading

Impact of Gender on Early Surgical Outcomes After Laparoscopic Surgery for Rectal Carcinoma.
Introduction: Controversies still persist regarding the appropriateness of laparoscopic surgery in patients with rectal carcinoma because of the uncertainty of long-term outcome, and of concerns over the safety of the procedure. Recently, several studies analyzing the risk factors of laparoscopic surgery for rectal carcinoma have been reported, and in some reports, male gender has been… Continue Reading

Impact of Laparoscopic Anterior Resection on Postoperative Bowel Function
yBackgroundzLaparoscopic anterior resection would be beneficial not only cosmetic aspect and less invasiveness but also for postoperative bowel function compared to those of open surgery.yMethodszTwenty patients had laparoscopic anterior resection (LAP) and pre- andpostoperative anorectal physiologic investigation by patientsf questionnaire andmanometry. These factors were compared with 25 open anterior resection candidate(OP) in the same period.… Continue Reading
