Laparoscopic Cholecystectomy Poses Physical Injury Risk to Surgeons: Analysis of Hand Technique and Standing Position
Introduction: This study compares the effects of surgical techniques (one-handed versus two-handed) and surgeon’s standing position (side-standing versus between-standing) during laparoscopic cholecystectomy (LC) and its outcomes on surgeons’ learning, performance, and ergonomics. There is little homogeneity in how to perform and train for LC. Variations in standing position (“American” or side-standing technique where the surgeon… Continue Reading
Prospective Non-randomized Study of Endoscopic Transvaginal Cholecystectomy Versus Laparoscopic Cholecystectomy
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. At the present time these procedures are hybrids. It is expected a better cosmetic result and lower incidence in parietal complications in front of laparoscopic cholecystectomy, but is necessary… Continue Reading

Reoperative Antireflux Surgery for Dysphagia
Background: Little is known regarding the predictors of favorable outcomes following re-do Anti-reflux surgery (Re-ARS). The aims of this study were: (1) to analyze the efficacy of Re-ARS in resolving dysphagia; and (2) to identify risk factors for persistent or new-onset dysphagia after Re-ARS. Methods: After IRB-approval, a prospectively maintained database was retrospectively reviewed to… Continue Reading

Sex Isn\’t Everything: The Role of Gender in Early Performance of a Fundamental Laparoscopic Skill
INTRODUCTION: Existing literature on the acquisition of laparoscopic skills suggests that gender affects initial performance, with women generally performing more poorly than men. This literature is limited by looking at an arbitrary number of initial attempts and not adjusting for other factors that may impact surgical performance. The objective of this study was to evaluate… Continue Reading

Fibrin Glue for Intraperitoneal Laparoscopic Mesh Fixation: A Comparative Study in a Swine Model
Introduction: A conventional method of mesh fixation in laparoscopic ventral hernia repair is transfascial sutures with tacks. This method has been associated with low recurrence rates, but yields significant morbidity from pain and bleeding. Fibrin glue has been used successfully in inguinal hernia repairs with decreased incidence of chronic pain without an increase in recurrence… Continue Reading

Esophageal Stent Placement Provides Safe Closure Following Transesophageal Access for NOTES® Thoracic Procedures
INTRODUCTION: Safe esophageal closure remains a challenge in transesophageal Natural Orifice Transluminal Endoscopic Surgery (NOTES) procedures. Suturing or t-tag devices are time consuming and risk organ injury due to their blind deployment. Endoclips are difficult to place in the narrow esophagus and submucosal tunneling techniques do not necessarily prevent leakage of esophageal contents into the… Continue Reading

Sensing Forces in Natural Orifice Surgery
INTRODUCTION. The purpose of this study is to determine the typical forces that instruments must be able to exert on tissue when performing surgery in the abdomen while accessing the tissue through natural orifices. The feasibility of NOTES is currently limited by a number of factors including the lack of suitable instruments. Current instruments are… Continue Reading

Single Incision Laparoscopic Cholecystectomies Cost Comparison
Objective: Cholecystectomy performed using the Single Incision Laparoscopic Surgery (SILS) technique should not cost significantly more or less than standard multiport cholecystectomy. Single access techniques are becoming more common for a multitude of laparoscopic procedures. Criticism has revolved around potential costs associated with increased operative time and use of innovative equipment. Methods: Retrospective cost data… Continue Reading

The Impact of Surgeon Behavior on the Cost of Performing Laparoscopic Appendectomy
INTRODUCTIONWhile laparoscopic appendectomy (LA) can be performed using a myriad of techniques, the cost of performing each method can vary considerably. The purpose of this study is to analyze the effects of the surgeon’s choice of technique on the costs of performing LA.METHODSThe surgeon operative notes, hospital invoice list, and surgeon instrumentation preference sheets were… Continue Reading

Is the Use of T-tube Necessary After Laparoscopic Choledochotomy?
Background. Traditionally, the common bile duct (CBD) is closed with T-tube drainage after choledochotomy and removal of CBD stones. However, the insertion of a T-tube is not without complication. Aim of Work. This randomized study was designed to compare the use of T-tube and primary closure of choledochotomy after laparoscopic choledochotomy to determine whether primary… Continue Reading

Real-time Intraoperative Detection of Tissue Hypoxia in Endoscopic Gastrointestinal Surgery By a Novel Wireless Pulse Oximeter (wipox)
ObjectiveDehiscence or leakage following bowel anastomoses occurs at a rate of 0-50% with a high associated mortality. Vascular perfusion and tissue oxygenation (SpO2) at the anastomotic site are fundamental determinates of anastomotic viability. We aimed to construct a wireless pulse oximeter (WiPOX) to monitor intraoperative real-time tissue oxygenation, permitting the identification of unrecognized compromised blood… Continue Reading
Neuroergonomic Assessment of the Robotic Enhancement of Minimally Invasive Surgery
Objective of the StudyMinimally invasive surgery (MIS) offers clear benefits to patients yet places increased demands on the surgeon. This is in part due to a lack of depth perception and haptic feedback and poor instrument ergonomics. Robotic assisted MIS aims to address these challenges. An example of this is Gaze-Contingent Motor Channelling (GCMC). GCMC… Continue Reading
Effects of Nissen Fundoplication on Ablation of Barrett\’s Esophagus with Endoscopic, Endoluminal Radiofrequency Ablation
Background: Endoscopic, endoluminal radiofrequency ablation is achieving increasing acceptance as a mode of eliminating Barrett’s metaplasia and, thus, reducing the risk of developing esophageal adenocarcinoma. It is believed that reducing the exposure of the esophageal epithelium to acid is essential to achieve long-term ablation of Barrett’s esophagus. However, it is unclear whether the use of… Continue Reading

A Prospective Randomized Study Comparing Suture Mesh Fixation Vs Tacker Mesh Fixation for Laparoscopic Repair of Incisional and Ventral Hernias
BackgroundRecurrence is one of the major problems after open incisional hernia repair. Laparoscopic incisional hernia repair has brought down the recurrence rate to less than 10%. The main causes of recurrence have been inadequate mesh size, fixation of mesh and patient factors. The issue of mesh fixation to the abdominal wall in laparoscopic ventral hernia… Continue Reading
