The purpose of this study was to determine whether the prophylactic use of a biologic prosthesis protects against the development of incisional hernia in a high-risk patient population. A prospective, nonrandomized trial was conducted on 134 patients undergoing open Roux-en-Y gastric bypass by a single surgeon, at two institutions, from January 2005 to(More)
BACKGROUND Morbid obesity is associated with an increased incidence of gallstones. Rapid weight loss, as occurs after Roux-en-Y gastric bypass (RYGBP) may also increase gallstone development. Standard surgical treatments for gallbladder disease and its complications might be more difficult following RYGBP. Controversy still exists whether prophylactic(More)
BACKGROUND There are few studies that compare the incidence of incisional hernia following elective laparoscopic colon resection to open colectomy and determine the risk factors for its development. METHODS Elective open and laparoscopic colon resections performed between February 2002 and May 2007 were reviewed. In the laparoscopic group, mesenteric(More)
BACKGROUND Roux-en-Y gastric bypass (RYGBP) reduces the co-morbidities of obesity. Patients with super-super obesity (BMI>or=60) present additional technical and medical challenges. This study compares the results in super-super-obese patients with patients with a BMI of <60 over a 5.5-year period. METHODS Retrospective analysis was performed of the 504(More)
BACKGROUND Despite the rapid rise in herbal medicine consumption, explicitly eliciting and documenting herbal medicine usage among surgical patients is poor. STUDY DESIGN A survey by means of a self-administered questionnaire was conducted among patients undergoing elective surgery inquiring into the self-health perceptions, herbal medicine use, and(More)
Recent technologic advances in video equipment and instruments have enabled therapeutic gastrointestinal operations to be performed laparoscopically. Using these advances and laparoscopic techniques, we have performed a Stamm gastrostomy with gastropexy by using the laparoscope in a single patient. The technique, indication, and considerations are discussed(More)
BACKGROUND Left-handedness has been considered a simple inconvenience by some or something as convoluted as "the sinister," the Latin word for the left, by others. One in ten medical personnel is left-handed. The perceptions of left-handed surgeons regarding their laterality related inconveniences are unknown. OBJECTIVES To determine the perceptions of(More)
The records of 6,452 consecutive patients who underwent cardiopulmonary bypass procedures were examined for intra-abdominal complications. There were 60 complications in 51 patients for an incidence of 0.94 per cent. The mortality rate was 59 per cent. Complications included bleeding in the gastrointestinal tract in 20, intestinal ischemia in 16, acute(More)
Paraesophageal hiatus hernia can be a morbid and even lethal condition. Although many complications from this entity have been described, they almost always involve gastric incarceration and its related complications. Occasionally, the transverse colon or spleen may be involved in the hernia, causing additional symptoms. An unusual case of paraesophageal(More)
