All so-called simple fistulas-in-ano may not have readily detectable primary openings and may possess secondary tracks which preclude their behavior as simple fistulas.
The incidence of unplanned related readmissions 90 days after abdominal or perineal colon resection is 9 percent, and these readmissions could not be predicted from the postoperative course. Because 82 percent of unplanned readmissions occurred within 30 days, this time frame is suitable for computerized comparative analysis.
This study demonstrates the validity of a simple technique of transanal repair of rectocele in an ambulatory setting. Minimal morbidity and successful outcome can be achieved with this procedure.
Over a 10-year period 69 patients were treated consecutively for posterior and anterior horseshoe abscesses and fistulas. Fifty-nine patients had posterior and ten had anterior abscesses or fistulas. There were 52 patients with acute abscess. Treatment consisted of incision and drainage, incision and drainage with primary fistulotomy, incision and drainage with primary fistulotomy and counter-drainage, and incision and drainage with insertion of seton. Seventeen patients with chronic fistulas were treated by primary fistulotomy with curettage, or incision and drainage with insertion of seton. Patients were followed from three months to ten years with a mean follow-up of three years. No incidences of incontinence were reported in this series. The overall rate of recurrence was 18 percent, and included only patients with posterior abscesses and fistulas. Recurrence was related to the failure to maintain prolonged drainage in the midline after primary fistulotomy. The use of seton for delayed fistulotomy appears to promote wound drainage and precludes premature wound closure. More liberal use of the seton in the treatment of horseshoe abscesses and fistulas is advocated.
Delayed hemorrhage following surgical hemorrhoidectomy is a well-recognized complication. Emergency treatment may include suture ligation, anal packing, or other means of tamponade. At the Lehigh Valley Hospital, 27 patients were seen with the complication of delayed hemorrhage over an eight-year period from 1983 to 1990, for an incidence of 0.8 percent. Twenty-five patients (93 percent) underwent surgery primarily for hemorrhoidal disease; one patient had hemorrhoids removed in addition to a sphincterotomy for anal tissue, and the remaining patient had hemorrhoidectomy with fistulotomy. The mean interval from the operation to hemorrhage was six days. Treatment modalities included bedside anal packing in 20 patients (74 percent), observation alone in five patients (18 percent), and suture ligation in the operating room in two patients. Anal packing was successful in controlling postoperative hemorrhage in 20/20 patients, but late complications requiring reoperation developed in 15 percent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
