Risk Factors for Postoperative Bleeding After Laparoscopic Appendectomy – Staple Size Matters
It is estimated that approximately 250,000 cases of appendicitis occur annually in the United States, with a lifetime risk of over 8% in males and 6% in females. Since the first description of laparoscopic appendectomy by Semm in 1983, multiple studies have validated its use in the treatment of acute appendicitis. The most common complication… Continue Reading

Does Incision Length Have Any Impact on Short Term Benefits of Laparoscopic Colon Surgery?
INTRODUCTION: With the recent introduction of hand-assist devices in laparoscopic colorectal surgery, there is renewed interest in the impact of incision length. The aim of this study is to define the impact of incision length on short-term postoperative outcomes.METHODS: Consecutive patients undergoing laparoscopic left-sided colorectal resection by 4 surgeons from 4 different academic centers from… Continue Reading

What is the definition of “conversion” in laparoscopic surgery among colorectal surgeons? a survey among SAGES and ASCRS
Background: Various definitions are used in the literature to define conversion, rendering comparison among studies difficult. A web-based and postal survey was conducted among colorectal surgeons representing the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and the American Society of Colon and Rectal Surgeons (ASCRS) regarding their definition of conversion during laparoscopic colorectal surgery… Continue Reading

Utilization of Laparoscopic and Open Inguinal Hernia Repair
BACKGROUND: Laparoscopic inguinal hernia repair is a safe and effective treatment for inguinal hernias, and is considered by some to be the procedure of choice for recurrent inguinal hernias. Little is known, however, about the frequency with which laparoscopic inguinal hernia repair is performed and the determinants of its utilization.METHODS: We performed a retrospective cohort… Continue Reading

Does Access to Minimally Invasive Surgery Account for Racial Differences in Surgical Outcome
Introduction: Minority populations consistently demonstrate poorer medical and surgical outcomes. Given that surgery is a rapidly evolving field, we hypothesized that poorer surgical outcomes by black patients are related to lack of access to minimally invasive surgery (MIS). Methods: We used data from the Nationwide Inpatient Sample, a 20% stratified random sample of patients admitted… Continue Reading

Intraoperatively-Acquired Objective Measures to Monitor Laparoscopic Skills
Introduction: Standard skill evaluation methods in the operating room (OR) include direct observation and checklists; both are time consuming and subject to bias. Objective assessment systems have been proposed for simulators using dexterity measures. However, motor performance in simulators can differ from that in the OR, so monitoring motor performance in the OR is necessary… Continue Reading

Validation that a one-year fellowship in minimally invasive/bariatric surgery can eliminate the “learning curve” for laparoscopic Roux-en-Y gastric bypass (LRYGB): Fellows’ first 100 cases in practice replicate the quality of their training institution.
INTRODUCTION: The concept that advanced surgical training can reduce or eliminate the “learning curve” for complex procedures makes logical sense but is difficult to verify and has not been tested for LRYGB. We sought to determine if minimally invasive / bariatric surgery fellowship graduates would demonstrate complication-related outcomes (CRO) equivalent to the outcomes achieved during… Continue Reading

When Surgery Stops: A Quantitative Video Analysis of Workflow During Laparoscopic Surgery
Introduction: Interruptions in surgical workflow has been shown to lead to OR inefficiencies and patient injury; however, we lack knowledge as to what causes these interruptions and to what degree these interruption affect the procedure time (PT). Workflow is a result of teamwork, thus interruptions were analyzed based on their effect on the teamwork rather… Continue Reading

A Model for Longitudinal Mentoring and Telementoring of Laparoscopic Colon Surgery
OBJECTIVE: To demonstrate the feasibility of longitudinal mentoring and telementoring of community surgeons in laparoscopic colon surgery.METHODS: A formal mentoring protocol was established between a university centre and surgeons at a local 134 bed community hospital 60km away. The community surgeons (CS) attended a didactic course on laparoscopic colon surgery before attending surgery at the… Continue Reading

Laparoscopic Nissen Fundoplication Assessment: Task Analysis as Model for the Development of a Procedural Checklist
Objective: Learning an advanced laparoscopic procedure is a complex process that requires clinical exposure, direct teaching, and deliberate practice. However, expert laparoscopic surgeons automate their knowledge making it difficult to teach all of the incremental steps. The aim of this study was to deconstruct the operative steps of a laparoscopic Nissen fundoplication (LNF) and develop… Continue Reading

Do Hybrid Simulator-generated Metrics Correlate with Content Valid Outcome Measures?
Objective: Hybrid simulators provide objective metrics for laparoscopic task performance. The aim of this study was to evaluate the correlation between hybrid simulator-generated metrics and content valid outcome measures.Methods and Procedures: Residents underwent training with a previously validated 5-task simulation model (5-TSM). Tasks included: clip/divide vessel, excise lesion, loop appendectomy, mesh placement with tacks, and… Continue Reading

Surgical Simulation in Africa: The Feasibility and Impact of a Three Day Fls Course
Introduction: Although simulation is now considered important for learning technical skills, there is very little literature assessing the use of simulation in resource restricted countries. The purpose of this study was to determine the feasibility and impact of a three day Fundamentals of Laparoscopic Surgery (FLS) course in Botswana, Africa. Methods: A total of 20… Continue Reading

Human Transvaginal Cholecystectomy using an IT-Knife
Background: NOTES is an evolving and controversial field of surgery on its beginning. Laparoscopic surgery and Endoscopy merges to fulfill it. Despite NOTES human experience had begin by the transgastric way with Rao in India, the transvaginal approach is taking place as a safer and easy way to achieve the upper abdomen. As on its… Continue Reading

Natural Orifice Transesophageal Mediastinoscopy and Thoracoscopy: A Survival Series in Swine
Introduction: Mediastinoscopy (MX) and thoracoscopy (TX) are common procedures with painful incisions and prominent scars. A natural orifice transesophageal endoscopic surgery (NOTES) approach could reduce pain, eliminate intercostal neuralgia, provide access to the posterior mediastinal compartment or hilum, and improve cosmesis. The purpose of this study is to create a survival animal model for NOTES… Continue Reading
