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.
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.
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 fistulotomy and counter drainage with no recurrence. Therefore, nine additional patients underwent this procedure. Recurrent horseshoe abscess fistula occurred in 2 of 11 patients (18.1 percent). Seton fistulotomy with counter drainage has become the authors' operative procedure of choice for horseshoe abscess fistula. This method may prove more effective if the true primary abscess cavity is identified, the seton is removed appropriately, and postoperative care of the cavity is adequate. Method of management is discussed.
Acute hemorrhoidal crisis can occur in the pregnant female. When medical therapy fails to relieve pain, operative intervention may be necessary. The surgeon, however, may be reluctant to operate due to potential complications to the mother and fetus. From July 1983 to July 1989, hemorrhoidectomy was performed in 25 of 12,455 pregnant women (0.2 percent) who delivered in our institution. Twenty-two women were in their third trimester, 80 percent were multiparous, and each had a remote history of hemorrhoidal symptoms, including intermittent pain, bleeding, and protrusion. Closed hemorrhoidectomy was performed under local anesthesia. The surgery was directed at removing only symptomatic disease, which included three quadrants in 14 patients, two quadrants in seven patients, and one quadrant in four patients. All patients experienced relief of intractable pain the day after surgery, except one patient who required a hemostatic packing during the immediate post-operative period. There were no other maternal or fetal complications. Subsequent follow-up for anorectal disease ranged from 6 months to 6 years. Six (24 percent) patients required additional hemorrhoid treatment. Hemorrhoidectomy in selected pregnant patients is safe in our experience.
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.
