A total of 1355 patients underwent internal sphincterotomy for chronic fissure in ano between 1980 and 1985. Surgical data were obtained for 1102 patients, and 829 patients responded to a questionnaire. Of the 1057 for whom the time of healing was recorded, 1033 (97.7 per cent) healed by a mean time of 5.6 weeks. No significant differences in satisfaction with the outcome or in deficits in continence were noted between groups undergoing lateral, bilateral or posterior midline sphincterotomy. Excision of the fissure was found to be unnecessary. According to responses on the questionnaires, deficits in continence ranging from 'sometimes' to 'frequently' included lack of control of flatus (35.1 per cent), soiling of underclothing (22.0 per cent) and accidental bowel movements (5.3 per cent). A significantly higher proportion of patients who had accidental bowel movements were aged over 40 years.
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.
Results showed no difference in the perception of pain after hemorrhoidectomy in patients who had an internal sphincterotomy compared with those who did not. Both groups were equally likely to have difficulty with control of gas and soiling.
A modification of Sullivan's procedure for endorectal repair of "low" rectocele was completed in 59 patients with local anesthesia. Associated anorectal pathology was corrected in all patients. The technique is described. At follow-up, the results were as follows: 37 excellent (62.7 per cent), 10 good (16.9 per cent), eight fair (13.6 per cent), and four poor (6.7 per cent).
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.
Administration of general, spinal, or epidural anesthesia for the procedure for prolapsing hemorrhoids is well described. This study suggests that the use of local anesthesia supplemented with conscious sedation for the procedure for prolapsing hemorrhoids yields results equivalent to those achieved with general or regional anesthesia without the attendant risks and additional costs. This study also suggests that the presence of muscle fibers in the pathologic specimen does not seem to lead to increased pain or impaired continence, although it was not specifically designed to address this issue.
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.
