INTRODUCTION Readmission after discharge from the hospital is an undesirable outcome. In an attempt to prevent unplanned readmissions after abdominal or perineal colon resection, we proposed to identify risk factors associated with return to the hospital. METHODS Study participants consisted of 249 patients who were operated on from July 1, 1996, to March(More)
Clinically significant hemorrhage following colonoscopic polypectomy may occur primarily as the polyp is removed or manifest itself days to weeks later secondary to clot dissolution. The rate of hemorrhage following colonoscopic polypectomy ranges widely from 0.3 to 6.1 percent, depending on whether the data are derived from studies using the number of(More)
PURPOSE Reports of virtual colonoscopy demonstrate sensitivity similar to that of conventional colonoscopy for polyps 5 mm or larger, suggesting the validity of its use for colorectal cancer screening. Critical to the success of either procedure is the ability to evaluate the entire colon. Cecal intubation rates during diagnostic or screening colonoscopies(More)
Recent studies have shown improved outcomes after laparoscopic colorectal surgery compared with laparotomy for surgery for both benign and malignant colorectal diseases, including inflammatory bowel disease (IBD). This study was designed to evaluate the results of laparoscopic colorectal resections in normal weight patients compared with overweight and(More)
Dieulafoy's lesion is an unusual source of massive lower gastrointestinal hemorrhage. It is characterized by severe bleeding from a minute submucosal arteriole that bleeds through a punctate erosion in an otherwise normal mucosa. Although Dieulafoy's lesions were initially described only in the stomach and upper small intestine, they are being identified(More)
AIM The aim of the study was to correlate the presence and pattern of distribution of granulomas in resected specimens to clinical characteristics and outcome in patients undergoing surgery for Crohn's disease. METHOD Patients with Crohn's disease who underwent surgical resection between 2001 and 2007 were identified. Pathology slides were reviewed for(More)
AIM The sensation that the rectum remains or is functioning after abdominoperineal excision (APE) is called phantom rectum (PR). Its postoperative and long-term morbidity are not well documented. Informed consent may not include the risk and consequences of this condition. We assessed the incidence and morbidity of PR after APE and compared those with vs(More)
It should be recognized that these guidelines should not be deemed inclusive of all proper methods of care or exclusive of methods of care reasonably directed to obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all of the circumstances presented by the individual(More)
BACKGROUND Transanal repair of rectocele involving the suprasphincteric portion of the rectovaginal septum has been shown to provide excellent results in up to 90 per cent of cases. Selection of patients suitable for repair is important. Rectocele with concomitant cystocele is best repaired transvaginally. An alternative approach is recommended for(More)
A study was undertaken to analyze seton fistulotomy with counter drainage as a treatment modality for horseshoe abscess fistula. In a previous report of 27 patients with partial or complete horseshoe abscess fistula, 24 patients underwent primary fistulotomy and counter drainage with a recurrence rate of 28.6 percent. Two patients were treated by seton(More)
