BACKGROUND Bladder and sexual dysfunction, secondary to pelvic nerve injury, are recognized complications of rectal resection. This study investigated the frequency of these complications following laparoscopically assisted and conventional open mesorectal resection for cancer. METHODS A total of 170 patients with rectal cancer was identified from a(More)
PURPOSE Stapled hemorrhoidectomy is performed without leaving painful perianal wounds. The aim of this study was to assess any benefits, compared with a conventional open diathermy technique. METHODS A total of 119 consecutive patients with prolapsed irreducible hemorrhoids were randomly assigned (conventional open diathermy technique = 62; stapled(More)
OBJECTIVE To assess the efficacy of a novel coloplasty colonic pouch design in optimizing bowel function after ultralow anterior resection. SUMMARY BACKGROUND DATA A colonic J-pouch may reduce excessive stool frequency and incontinence after anterior resection, but at the risk of evacuation problems. Experimental surgery on pigs has suggested that a(More)
Clinical function and anorectal physiology were studied prospectively in patients with rectal cancer after low anterior resection, randomized to either a straight anastomosis or an 8-cm colonic J pouch anastomosis. Sixteen patients (mean(s.e.m.) age 61.2(3.2) years; ten men, six women) had a straight anastomosis and 17 (mean(s.e.m.) age 61.2(3.8) years; six(More)
Twenty patients (13 men) with low rectal cancer, median (range) age 64.5 (38-83) years were prospectively randomized to undergo ultra-low anterior resection with a J colonic pouch-anal anastomosis (median (range) distance of anastomosis from the anal verge 3 (1-4) cm). Another 20 patients (15 men), median (range) age 62.5 (44-86) years) with low rectal(More)
BACKGROUND Laparoscopic surgery is believed to produce an attenuated metabolic stress response and to have a less dampening effect on the immune response than open surgery. To date, the effect has not been studied in a randomized clinical trial of colorectal cancer. METHODS The study was a two-armed randomized prospective trial conducted in parallel with(More)
PURPOSE Primary fistulotomy may be advantageous for perianal abscesses because unlike ischiorectal abscesses, fistulas are more commonly found and can be laid open with full preservation of the external anal sphincters. Therefore, a randomized, controlled trial was conducted to compare primary fistulotomy with incision and drainage alone, specifically for(More)
BACKGROUND Aggressive therapeutic regimens have been advocated for the treatment of peritoneal carcinomatosis from colorectal cancer. It is essential to understand the clinical and histological features that govern the natural history of this condition if the efficacies of novel therapeutic approaches are to be assessed adequately. METHODS A database of(More)
A prospective randomized controlled trial was carried out on the effects of Daflon 500 mg (a micronized flavonidic fraction containing diosmin 450 mg and hesperidin 50 mg) on bleeding after haemorrhoidectomy. In all, 228 consecutive patients with prolapsed irreducible piles were recruited. Elective haemorrhoidectomy was performed with a standardized(More)
BACKGROUND Conventional stapled haemorrhoidectomy involves the use of a large circular anal dilator (DL technique), which may cause anal sphincter injuries. This study compared whether the procedure can be effectively performed without this dilator (ND technique), with better sphincter preservation. METHODS Fifty-eight patients with symptomatic prolapsed(More)
