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

Does an Infrared Laparoscope bring better visual field under the bleeding situation?
Back ground: The bleeding during the laparoscopic surgery adds much stress to the surgeons. Our experiences of near-infrared (NR) laparoscope that used for sentinel lymphnodes detection inspired the possibility of better visualization under the bleeding situation. Therefore, we examined the visibility of NR scope on an experimental basis.Materials and Methods: NR scope (805}15nm: Olympus Corp.)… Continue Reading

Does Elevated Gastric pH Affect the Detection of Gastroesophageal Reflux Using 24 hr Esophageal pH monitoring?
Introduction:24 hour esophageal pH is the most widely used method to quantify Gastroesophageal reflux (GER). GER may potentially be underestimated if the resting gastric pH is high. However, the value of routine assessment of gastric pH in the performance of 24hr esophageal pH monitoring is unclear. We studied normal subjects and symptomatic patients undergoing 24… 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

Does Increasing Experience with Laparoscopic Colorectal Surgery Influence the Outcome of Complex Cases?
OBJECTIVES: To define major risk factors for intraoperative complications (IOC) in laparoscopic colorectal surgery, and to assess whether surgeon experience influences the outcomes of complex cases.METHODS: Consecutive patients undergoing laparoscopic colorectal procedures from 1991-2005 were analyzed from a prospectively-collected database. All patients referred to the four surgeons involved in this study were offered a minimally… Continue Reading

Does Liberal IV Fluid Administration Decrease Post-Op Nausea and Vomiting in the Bariatric Surgery Patient? a Double Blinded, Randomized Trial
IntroductionPost-operative nausea and vomiting (PONV) represents a serious and vexing problem after bariatric surgery. We hypothesized that liberal administration of IV fluid administration may influence PONV. Methods50 patients were recruited from a bariatric surgery clinic in an academic hospital. Patients were randomized to two groups of intra-operative IV fluid administration: Group A received 15ml/kg while… Continue Reading

Does robotic assistance improve efficiency in performing complex minimally invasive surgical procedures?
OBJECTIVE: We developed a model of biliary-enteric anastomosis to test whether assistance with the da Vinci surgical system, as compared to laparoscopy alone, improves performance on a complex minimally invasive surgical (MIS) procedure. METHODS: An ex vivo model for choledocho-jejunostomy was created using specimens of porcine liver that included an intact extrahepatic biliary system and… Continue Reading
Does Telementoring Shorten the Pathway to Proficiency in the Simulation Environment?
Introduction: Telementoring(TM) is an emerging tool that enables experts to provide consultation to other surgeons remotely. It has not been studied in the simulation environment. Simulation allows residents to train independently to gain proficiency. The aim of this study is to assess the effectiveness of distant telementoring in a simulated mock operating room to identify… Continue Reading

Double tract reconstruction after laparoscopy-Assisted distal gastrectomy
Background: Laparoscopy-assisted gastrectomy (LADG) was reported by Kitano et al. in 1994. It is currently one of the option for early gastric cancer treatment. The common reconstruction has been Billroth I method. The roux-en-Y anastomosis is recommended by some surgeons regarding alkaline reflux gastritis, esophagitis, dumping syndrome, and carcinogenesis of the remnant stomach. However, endoscopic… Continue Reading

Drain Amylase Levels in Roux-en-Y Gastric Bypass: What Is a Normal Value?
INTRODUCTION: Anastomotic leak from the gastrojejunostomy (GJ) is a serious complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). Normal imaging and a benign abdominal exam does not exclude the presence of a leak. The effluent from a GJ leak is composed primarily of salivary secretions and thus should have a high amylase level. The measurement of… Continue Reading

Durability of a Novel Full Thickness Percutanous Endoscopic Sleeve Gastroplasty (pesg): Survival Study
Background: Percutaneous endoscopic sleeve gastroplasty (PESG) may have a role as a restrictive weight loss procedure. We hypothesize that we can safely perform a durable PESG using full thickness endoluminal plications. Methods: After developing the PESG on ex-vivo porcine stomachs and 6 non-survival procedures, we tested the durability by performing 6 survival procedures on 30… Continue Reading

Durability of an Endoscopic Endolumenal Gastric Plication
Objectives: The goal of our study was to determine the safety and durability of an endolumenal plication of the stomach. Methods and Procedures: Ten 25-kg female swine underwent standard upper endoscopy, during which a single, 12 mm intragastric laparoscopic trocar was placed. Using the EndoStitch device (U.S. Surgical), an 8cm gastric sleeve was created by… Continue Reading

Dysphagia after using a Biological Mesh to Repair a Recurrent Hiatal Hernia
Introduction: It has been recently demonstrated in a controlled trial that reinforcement of the crura with a biological mesh decreases the incidence of recurrence of paraesophageal hernias after hiatal repair. This technique is therefore increasing in popularity. Complications from this type of mesh have not been reported, but an animal study has suggested that a… Continue Reading

Dysregulation of Gene Expression within the PPAR pathway in Obese Patients
Background: The causes of obesity are multifactorial and may include dysregulation of certain genes, such as peroxisome proliferator activated receptor gamma (PPAR gamma). When activated, the PPAR gamma pathway promotes lipid metabolism. This study uses microarray technology to evaluate differential gene expression profiles in obese patients undergoing bariatric surgery versus non-obese controls. Methods: Blood samples… Continue Reading

Early Conversion in Gangrenous Cholecystitis
INTRODUCTION: Early conversion from laparoscopic to open cholecystectomy for patients with gangrenous cholecystitis has been advocated. This study investigated the impact of early conversion on patient outcome. AIMS & METHODS: Data from all patients with gangrenous cholecystitis undergoing laparoscopic cholecystectomy between 1995 and 2006 whose procedure had been converted to open surgery were collected and… Continue Reading
