Dilation of Anastomotic Strictures After Transhiatal Esophagectomies
Objective: Anastomotic stricture presenting with dysphagia after transhiatal esophagectomy is a common problem. We have reviewed our experience with esophageal dilatations after transhiatal esophagectomies. Methods: We retrospectively reviewed the medical records of all patients who underwent esophageal dilatation after transhiatal esophagectomies. Demographic data, number and methods of dilatations, time between dilatations, and time between surgery… Continue Reading

Does Medically Supervised Weight-loss Effect Weight Loss After Bariatric Surgery?
Introduction: It is a proven fact that the bariatric surgery is effective in the treatment of morbid obesity and as a consequence results in the improvement/resolution of obesity associated comorbidites. Yet health insurers have stringent guidelines for indication of bariatric surgery which includes multidisciplinary evaluation with different time lengths of mandatory medically supervised weight loss… Continue Reading

Does Operative Time Influence Outcome in Patients Undergoing Laparoscopic Colorectal Surgery?
Laparoscopy has gained acceptance for the treatment of many colorectal disorders. However, the reality that laparoscopic cases are often time consuming and take longer than the conventional open approach has led to speculation that increased operative time may negatively affect the overall patient outcome. We examine all laparoscopic cases performed by a single surgeon (N… Continue Reading

Does Preoperative Endoscopy in Bariatric Surgery Alter the Medical or Surgical Strategy?
Introduction: Controversy exists as to the need for preoperative esophago-gastro-duodenoscopy (EGD) for patients undergoing bariatric surgery. Specifically, do findings alter the medical and surgical management. The purpose of this study is to evaluate the role of preoperative EGD in the therapeutic strategy of bariatric surgery. Methods: We conducted a retrospective analysis of consecutive patients undergoing… Continue Reading
Does the Learning Curve During Laparoscopic Colectomy Adversely Affect Costs?
Background: The aim of this study is to investigate whether the learning curve during laparoscopic colectomy (LC) is associated with increased costs when compared with the procedure after the learning curve has been achieved.Methods: Direct costs for patients undergoing LC during the learning curve (Group A) and after the attainment of proficiency by two colorectal… Continue Reading

Does Visceral Fat Resection Give an Additional Benefit to Gastric Banding
Background Although the function of visceral fat has gradually become clear, the effect of visceral fat resection is still unknown. The aim of this study is to clarify the additional effect of visceral fat resection in an obese rat model of gastric banding. Methods Fourty male Zucker fatty rats were followed for 8 weeks after… Continue Reading

Duodenoscope Choice in Pediatric ERCP
Introduction: Although rare, some pediatric diseases may require diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). The choice of duodenoscope for pediatric ERCP is not well studied. This study investigated the hypothesis that a therapeutic adult duoenoscope can be utilized safely for pediatric ERCP. Methods: All patients under the age of 18 were included in this… Continue Reading

Early Effects of Bariatric Surgery on Pro and Anti-inflammatory Mediators and Cardiovascular Risk Factors
INTRODUCTION:Obesity is associated with a chronic inflammatory state and increased risk for cardiovascular disease. We hypothesize that gastric bypass is associated with rapid improvements in inflammatory mediators and cardiovascular risk.METHODS:We performed a prospective pilot study of morbidly obese patients who underwent laparoscopic Roux-en-Y gastric bypass. Patient demographics, clinical data and biochemical markers related to inflammation… Continue Reading

Early Re-exploration Following Incisional Hernia with Biologic Graft
Introduction:Biologic grafts have been used for the repair of complex abdominal wall defects. Although much is known about the remodeling process, their propensity to form adhesions in humans has not been well studied yet. We present a case of early re-exploration after a complex incisional hernia repaired with bovine pericardium graft.Methods:A 61 year-old man with… Continue Reading

Early Results of Laparoscopic Adjustable Gastric Banding in Bmi<35: The Appropriate Choice
Objective: Obesity is an epidemic in America and continues to worsen. Lifestyle modifications remain the first line in treatment, but typically fail for patients. As obesity worsens, the associated comorbidities become an expensive and time consuming aspect of our health care system. Placement of an adjustable gastric band in a low BMI population ( Session:… Continue Reading

Effect of Gastric Bypass on C-reactive Protein Levels: A Prospective Analysis
INTRODUCTION: Surgical treatment of morbid obesity improves many co-morbidities including diabetes, hypertension, sleep apnea, and asthma. Elevated CRP levels, common in the morbidly obese, and its reflected increase in cardiovascular and cerebro-vascular complications has led to further study in patients undergoing laparoscopic Roux-en-Y gastric bypass (LRGB). In this study we prospectively investigate the relationship between… Continue Reading

Effect of Laparoscopic Surgery on Surgeons\’ Health
A lack of understanding the ergonomics of laparoscopic surgery has a potential to pose health problems for the surgeons. This study was planned to asses the prevalence of ergonomic problems associated with laparoscopy. Questionnaires designed to asses the frequency and degree of physical discomfort practicing surgeons during laparoscopy were evaluated in 210 cases.The average age… Continue Reading

Effectiveness of a New Trocar System to Enable NOTES
Introduction: Natural orifice translumenal endoscopic surgery (NOTES) is a developing area of minimally invasive surgery. Fundamental challenges of NOTES include development of safe ways to perform translumenal access and maintaining visualization and spatial orientation using a stable operating platform. This study examines the functionality of a new rotary access needle (RAN) device and technique for… Continue Reading

Effects of Preventing Oxidative and Nitrooxidative Stress on Healing of Experimental Rat Colon Anastomosis
Introduction;Colon anastomosis is a frequently used technique.Decreasing oxidative substances may prevent surgeon from complications.We investigated the efficacy of N-acetyl cysteine(NAC) as an antioxidant, Ebselen as a peroxide reducer and 1400W as an inducible nitricoxide synthetase(INOS) inhibitor on ischemic and non-ischemic colon anastomosis. Methods and procedures; 90 Sprague-Dawley rats were used. Study design as follows;1)non-ischemic control… Continue Reading
