A Novel Sensorized Instrument-based Minimally Invasive Surgery (simis) Tool: Initial Construct Validation of Position Sensing
Objective: A novel sensorized laparoscopic instrument capable of sensing tip position in 6 degrees of freedom (DOF) and forces in 5 DOF was evaluated. The purpose of this research was to demonstrate that the position sensing component is construct valid as evidenced by different position profiles between novice and expert laparoscopic surgeons. Methods: Using an… Continue Reading

A Pilot Study of Using Multiphoton Microscopy to Diagnose Gastric Cancer
Introduction: Using a combination of autofluorescence from cells and second harmonic generation signal from collagen, multiphoton microscopy (MPM) imaging can provide detailed information on tissue architecture and cellular morphology. The purpose of this study was to evaluate the feasibility of using MPM to diagnose gastric cancer, compared with gold standard hematoxylin-eosin (H-E) stained histopathology.Methods: A… Continue Reading
A Preliminary Study on Preoperative Three-dimensional Simulation Using Mdct for Single Port Access Surgery on Gist
PURPOSERecently, Single Port Access (SPA) surgery becomes to be performed for cholecystectomy or gastrostomy. SPA surgery is performed using a single incision in the patient’s belly button. We try to remove gastric GIST using SPA plus one or two additional ports. However gastric wedge resection for GIST is variable about location or size comparing to… Continue Reading

A Proposed Classification System for Gastric Pouch Enlargement Associated with Laparoscopically Placed Adjustable Gastric Bands
INTRODUCTION: As morbid obesity becomes an increasingly frequent medical problem, novel surgical treatments to induce weight loss are being developed. The laparoscopic adjustable gastric band (LAGB), well proven to be a safe and effective means of weight loss, is such an example. Many of the complications related to the LAGB involve an excessive amount of… Continue Reading

A Prospective Cohort Study for Simple New Technique Two-incision Laparoscopic Cholecystectomy :
Background : Laparoscopic cholecystectomy ( LC ) has clearly become the procedure of choice for routine gallbladder removal. The advantages of this approach include decreased scarring, decreased incisional pain, shorter hospitalization and faster functional recovery.The recent years, many investigators have attempted to further improve on the established technique of LC. Generally, the goal has been… Continue Reading
A Prospective Randomized Study Comparing Laparoscopic Totally Extra Peritoneal (tep) Repair Versus Trans Abdominal Pre-peritoneal (tapp) Repair for Inguinal Hernia Repair
BackgroundLaparoscopic inguinal hernia repair has the advantage of lesser pain, early recovery and lesser wound morbidity. There is no consensus on the best groin hernia repair. There are two standard techniques of Laparoscopic Inguinal hernia repair – Total Extra Peritoneal repair (TEP) and Trans - Abdominal Pre-Peritoneal repair (TAPP). There are not many trials available… 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

A Retrospective Study Challenges the Construct Validity of Colonoscopic Virtual Training
Background Virtual gastrointestinal endoscopy trainers are often used as part of surgical residency-simulation training. The GI mentor has been shown to have construct and face validity with different level of learners in prospective cohort studies. It is unclear whether with prior exposure to these devices PGY1 and PGY2 residents become more adapt to these trainers… Continue Reading

A Review of Perioperative Complications in 120 Consecutive Community Based Laparoscopic Donor Nephrectomies
TITLE: A Review of Perioperative Complications In 120 Consecutive Community Based Laparoscopic Donor Nephrectomies INTRODUCTION: Throughout the mid 1990's and early 2000's numerous university programs compared perioperative complications in laparoscopic donor to the gold standard open technique in order to validate the emerging standard of care for nephrectomies. As innovation becomes the norm, an important… Continue Reading

A Scarless Cholecystectomy Made Easy By the Hidden Suprapubic Approach
Currently, a new trend for no scar procedures has become very popular, mainly for cholecystectomy. The needlescopic surgery is not suitable for complicated cases and the incisions are located at visible points. TUES procedure has a limited critical view and requires at least a 25 mm umbilical incision. NOTES requires a sophisticate endoscope through the… Continue Reading

A Simple ‘fundal Traction Suture\’ in Single Incision Laparoscopic Cholecystectomy
IntroductionThe last two years have seen numerous reports on single incision laparoscopic surgery (SILS) in surgical literature. Achieving an appropriate fundal traction is one among the many technical challenges while performing a SILS cholecystectomy. We describe herein a simple method of suture traction of gall bladder fundus during SILS cholecystectomy.MethodsProspective data of patients who underwent… Continue Reading

A Small Pouch Laparoscopic Adjustable Gastric Band (high Band) Is Associated with a Lower Incidence of Complications. Midterm Analysis of 132 Patients.
Introduction: Laparoscopic adjustable gastric banding (LAGB) is the least invasive procedure for surgical treatment of morbid obesity and is becoming a preferred method for surgical weight loss among bariatric patients in the USA. However, up to 20% of patients develop complications after the implantation of LAGB. Severe complications such as band migration, band infection, pouch… Continue Reading

Acceptance of Single Port Endoscopic Surgery (spes), NOTES and Laparoscopic Surgery in a Cohort of Surgical Patients
Introduction: Single Port Endoscopic Surgery (SPES) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) are the emerging surgical concepts of the 21st century. In both techniques the aim is to minimize the surgical aggression by reducing the entry ports and to have better cosmetic results. The aim of the current study is to assess the opinion… Continue Reading
