PURPOSE The study contained herein was undertaken to establish the incidence of small-bowel obstruction, adhesiolysis for obstruction, and additional abdominal surgery after open colorectal and general surgery. METHODS A retrospective cohort study was performed using patient-specific Health Care Financing Administration data to evaluate a random 5 percent(More)
PURPOSE This study was designed to assess the medical and surgical treatment of colonoscopic perforations. METHODS A retrospective review of colonoscopic perforations from 1970 to 1999 was performed. RESULTS In 30 years, 34,620 colonoscopies resulted in 31 (0.09 percent) perforations. Eighteen (58 percent) resulted from therapeutic colonoscopies,(More)
PURPOSE This study was undertaken to evaluate the incidence, diagnostic methods, and treatment of hemorrhage occurring after colonoscopic polypectomy. METHODS A retrospective chart review was conducted of 12,058 patients who underwent colonoscopy at an academic referral center between January 1989 and July 1993. Of these, 6,365 patients required(More)
PURPOSE The purpose of this study was to document prospectively the time required to gain access to the abdomen to perform a planned procedure in patients with and without previous surgery. METHODS Patients were obtained from the consecutive cases of 11 surgeons at three colorectal surgery centers. Opening time (skin incision to retractor placement) was(More)
PURPOSE This study was performed to evaluate whether the time interval from injection of technetium Tc 99m (99mTc)-labeled red blood cells to the time of a radionuclide "blush" (positive scan) can be used to improve the efficacy in predicting a positive angiogram. METHOD A retrospective review revealed 160 patients who received 99mTc-labeled red blood(More)
PURPOSE The aim of this trial was to evaluate the safety, efficacy, and impact on quality of life of the Acticon trade mark artificial bowel sphincter for fecal incontinence. METHODS A multicenter, prospective, nonrandomized clinical trial was conducted under a common protocol. Patients were evaluated with anal physiology, endoanal ultrasonography, a(More)
Peutz-Jeghers syndrome is a disease manifested by a combination of mucocutaneous pigmentation and gastrointestinal (GI) polyposis. The major morbidity results from intussusception, obstruction, and bleeding. Standard surgical management has been to perform enterotomies at the site of palpable polyps. A method of treating Peutz-Jeghers syndrome surgically(More)
Colonic diverticulosis predisposes individuals to lower gastrointestinal hemorrhage in up to 5% of cases. These sac-like protrusions are pseudodiverticula and arise due to a combination of anatomic, dietary, motility, and structural influences. In the setting of acute hemorrhage, patient stabilization takes priority, followed closely by maneuvers aimed at(More)
The purpose of this study was to evaluate the impact of adjuvant chemotherapy on survival after surgery for T3N0 colon cancer. All patients with node-negative (N0) colon cancer with tumor invasion beyond the muscularis propria (T3) treated with colectomy between 1982 and 1995 at a single institution were included. Patients were divided into two groups(More)
Widespread popularity of the double-stapler technique has created the potential for anal sphincter and anal canal injury during transanal insertion of the end-to-end anastomosing stapler. The Faensler operating anoscope helps eliminate that potential by symmetrically dilating the anal canal, thereby permitting atraumatic insertion of the end-to-end(More)
