Quality of life as determined by SF 36 health survey is significantly improved following laparoscopic gastric bypass. A prospective analysis of consecutive 300
Introduction: The short-form 36 (SF-36) health survey has proven to be a reliable tool when assessing the burden of disease on both physical and mental health. Moreover, it is widely used to assess the effects of various treatment options on the overall quality of life. Using the SF-36 questionnaire, our goal was to quantify the… Continue Reading

Quality of life significantly improves after laparoscopic gastric bypass
Introduction:The Moorehead-Ardelt Quality of Life Questionnaire (M-A QoLQ) has been validated as a reliable tool in assessing quality of life issues in the obese population. We compared the quality of life data gathered prior to and 1 year following laparoscopic bariatric bypass surgery using the M-A QoLQ on selected outcomes including self-esteem, physical, social, work… Continue Reading

Randomized blinded trial comparing NOTES with laparoscopy reveals no difference in immunologic parameters
Background: Natural Orifice Transluminal OrificeSurgery (NOTES) is being investigated for human use as a new minimally invasive procedure. We compared NOTES with the current gold standard laparoscopy.Hypothesis: Animals undergoing NOTES will reveal greater hemodynamic instability due to uncontrolled insufflation pressures. No difference in the immunologic impact as measured by Interleukin-1b will be realized.Design: Randomized blinded… Continue Reading

Real-Time Dynamics of Nitric Oxide within the Esophageal Wall
Objective: Current evidence suggests that the neurotransmitter Nitric Oxide (NO) plays a crucial role in the genesis of aboral propagative of esophageal peristalses during swallowing. However, direct evidence in this regard is lacking at present. The objective of this study was to measure changes in the level of NO within the intermuscular interstices of esophagus… Continue Reading

‘real-time\’ Measurement of Tissue Oxygenation During Gastrointestinal Stapling: Mucosal But Not Serosal Surface Ischemia Occurs and Is Not Influenced By Staple Size
Tension, tissue ischemia and technical error are known factors which can lead to anastomotic complications such as leak, stricture, and ulceration/bleeding. Currently surgeons evaluate tissue ischemia without benefit of any simple routine measurement technique to assess tissue viability. A new tissue surface probe (T-STAT microvascular tissue oximeter, Spectros Corporation, Portola Valley, California) provides continuous measurement… Continue Reading
Reducing the incidence of gastric prolapse after adjustable banding: A stitch away
Background: Laparoscopic adjustable gastric banding is gaining in popularity for the treatment of morbid obesity. While it garners successful weight loss, the postoperative course can be complicated by reoperations. Gastric prolapse after adjustable banding is the most common cause for reoperation, approaching up to 5% in many series. Using the Pars Flaccida technique, it is… Continue Reading

Repair of Ventral Hernias with Prosthetic Mesh During Laparoscopic Gastric Bypass May Be Safe
Background: Deferring the repair of a ventral hernia found at the time of an antecolic laparoscopic gastric bypass (LGB) increases the incidence of bowel obstruction. However, the optimal repair technique has not been established. The use of prosthetic mesh has been shown to decrease the recurrence of ventral hernias compared to primary closure, yet the… Continue Reading

Residents learning laparoscopic colonic resections. Is it safe?
Background: The learning curve in laparoscopy is usually associated with higher morbidity and conversion rate. Because laparoscopic colonic resection is a complex procedure it is commonly believed it can not be included in a general surgery program training.Aim: The aim of this study is to analyze the learning process of residents who perform laparoscopic colon… Continue Reading

Resolution of comorbidities following LRYGB: A prospective analysis of 434 patients
Introduction: Morbid obesity is a chronic disease that reduces life expectancy and represents a major risk factor for other chronic illnesses.1,2 At the present time bariatric surgery remains the only therapy that produces significant and sustained weight loss in the morbidly obese. Surgical weight reduction can reverse or eliminate many obesity related comorbidities.3 Materials and… Continue Reading

Results after laparoscopic Heller-Dor operation for esophageal achalasia in 100 consecutive patients
Background: Laparoscopic Heller-Dor operation (LHD) has been the procedure of choice for the treatment of esophageal achalasia. However since, the incidence of achalasia is low, at one in 100,000 in USA and Japan, reports on the outcome of surgical treatment for such a disease are limited. In this study, we investigated the therapeutic results after… Continue Reading

Retrievable Inferior Vena Cava Filters in High Risk Patients Undergoing Bariatric Surgery
Introduction: Placement of retrievable inferior vena cava filters (IVCF) may be beneficial in high risk morbidly obese patients undergoing bariatric procedures. Bariatric surgery patients with a prior history of venous thromboembolism (VTE) are at high risk for postoperative recurrent deep venous thrombosis (DVT) and pulmonary embolism (PE). Methods: A prospective database of morbidly obese patients… Continue Reading

Retroperitoneoscopic Necrosectomy and Drainage for Infected Pancreatic Necrosis
Background: Infected pancreatic necrosis is an indication for drainage and debridement, which has traditionally been treated by percutaneous drainage or open necrosectomy. However, percutaneous drainage is often unsuccessful because of difficulty in managing the particulate debris through small catheters. Open necrosectomy involves major morbidity and a high rate of repeated surgery for abdominal sepsis. Recently… Continue Reading
Retrospective study comparing laparoscopic and open resection for transeverse colon cancer
BackgroundAlthough the large randomized trials are going about laparoscopic-assited colectomy(LAC) versus open colectomy(OC) for cancer, all of thease excluded patients with transverse colon cancer. Our study aimed to compare efficacy and safty of LAC and OC for treatment of transverse colon cancer in terms of morbidity and tumor recurrence and survivals.MethodsFrom February,1995,to March 2007, all… Continue Reading

Rigid Transvaginal Retraction in Hybrid NOTES Cholecystectomy
Introduction: As techniques of natural orifice translumenal endoscopic surgery (NOTES) improve, the safe performance of totally translumenal surgery is becoming more feasible. In a previous report of a hybrid approach to natural orifice transvaginal cholecsytectomy we noted difficulty with gallbladder retraction and could only accomplish this transabdominally.We present a novel technique and instrument that allows… Continue Reading

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
