The effect of abdominal rectopexy on bowel function is difficult to assess in retrospective studies because preoperative bowel habit cannot be determined accurately. This study examined bowel symptoms and physiologic tests of anorectal function prospectively in 23 patients before and at three months after rectopexy. Rectopexy eliminated complete prolapse in all and stopped bleeding in 16 of 18 patients. Incontinence improved significantly. Constipation (less than 3 bowel actions per week or straining for more than 25 percent of defecation time) was relieved in 4 of 11 affected patients but developed in 5 of the 12 who were not constipated preoperatively. Since the median bowel frequency was 21 motions per week before surgery and 17 afterward, the main determinant of constipation was straining. Abdominal pain was relieved after rectopexy in 6 of 12 patients but developed in 3 of 13 who were pain-free before surgery. Three patients (13 percent) had a first-degree relative with rectal prolapse. Perineal descent decreased significantly. Maximal anal resting pressure increased significantly, but this did not correlate significantly with improved continence. Twenty-one patients (91 percent) could expel a 50-ml balloon preoperatively; 18 of those 21 could still do so postoperatively. The two patients who could not expel the balloon preoperatively were able to do so postoperative. This study shows that rectal prolapse is associated with profoundly abnormal defecation and abdominal pain. While abdominal rectopexy improved continence, it may improve or worsen other bowel symptoms, including constipation.

Patients on chronic hemodialysis for end-stage renal disease (ESRD) may develop anorectal problems necessitating surgery. From January 1984 to December 1987, 18 ESRD patients underwent anorectal surgery. During this period, a mean of 215 patients underwent dialysis. Patients with ESRD present with characteristic problems: chronic constipation, need for dialysis pre- and postoperatively with heparin infusion, anemia, anticoagulation secondary to the consequences of uremia, and significant medical problems including coronary artery disease, diabetes mellitus, hypertension, and chronic obstructive pulmonary disease (COPD). Two patients had concomitant anal fissure, two had fistula-in-ano, and one had an acute perianal abscess. In two patients, the postoperative course was complicated by hemorrhage and, in one patient, by abscess formation. There was no delay in wound healing compared with a cohort group. The essentials of perioperative management are discussed with respect to timing of dialysis, methods of anesthesia and pain management, coagulation screening, and complications. Patients on well-managed chronic dialysis will tolerate anorectal surgery without undue jeopardy.

In 12 patients suffering from chronic idiopathic anal pain, the rectosphincteric function was studied using manometric and x-ray techniques. The results of manometric investigations were compared with those obtained in 12 healthy volunteers. In all patients, the resting pressure in the anal canal was significantly higher than in control subjects. In 10 patients, defecography revealed abnormalities of the pelvic muscles. We treated the patients by using biofeedback techniques, consisting of voluntary modifications of the state of contraction of the external sphincter. In all cases, pain disappeared after a mean of eight biofeedback training sessions. When noxious manifestations had disappeared, manometry showed a significant decrease in the anal canal resting pressure. Our results indicate 1) that chronic idiopathic anal pain is associated with abnormal anorectal manometric profiles, probably resulting from a dysfunctioning of the striated external anal sphincter, and 2) that biofeedback training is an effective treatment for chronic idiopathic anal pain.

In 10 patients with emptying disturbances, the anal sphincter reaction was investigated clinically and by electromyography with needle and wire electrodes to elucidate whether pain during the investigation could provoke the paradoxical sphincter reaction. In eight of the patients, the paradoxical reaction was easily felt at digital examination. Two patients complained of pain during the needle electrode recording; none complained during the wire electrode investigation. Nevertheless, all 10 patients had paradoxical sphincter reaction independent of the electrode used at electromyography. With careful clinical investigation, most cases of paradoxical sphincter reaction can be diagnosed. When this is inconclusive, the diagnosis should be confirmed by electromyography, preferably by the wire technique.

Urinary retention is the most common complication after anorectal surgery, with rates as high as 52 percent reported. With the trend toward early discharge, avoidance of this complication is particularly important. Perioperative fluid restriction and the use of short-acting anesthetics have been shown to be effective in decreasing postoperative urinary retention rates but are not applicable in all cases. Reflex sympathetic stimulation, possibly as a result of perianal pain, may lead to increased muscular tone of the internal sphincter at the bladder neck. This theory had led to the effective use of alpha-adrenergic blockade in the treatment of established cases of urinary retention after anorectal surgery, herniorrhaphy, and major pelvic surgery. However, the prophylactic role of alpha blockade after anorectal surgery has not been studied. In a double-blind, prospective, randomized study, 51 patients were treated with either prazosin and alpha-adrenergic blocker or placebo prior to and immediately after elective anorectal surgery. Urinary retention rates were similar in the two groups. At this time, prophylactic alpha-adrenergic blockade is not recommended for the prevention of urinary retention after anorectal surgery.

Eighty-eight patients who received treatment for hemorrhoids were randomized into two groups. Group A received the Nd-YAG laser phototherapy for internal hemorrhoid combined with the CO2 laser for external hemorrhoid. Group B was treated with closed Ferguson hemorrhoidectomy. The need of narcotic injections for pain relief was 11 percent in group A vs. 56 percent in group B (P less than 0.001). The incidence of postoperative urinary retention was 7 percent in group A, vs. 39 percent in group B (P less than 0.05). No enema was required postoperatively in group A, vs. 9 percent in group B; 84 percent of the patients in group A were discharged on the second postoperative day, vs. 83 percent of the patients in group B discharged on the fifth postoperative day. The cost was 20 percent less in the former group. The overall complications in both groups were insignificant in difference, except prolonged wound healing in group A was noted. One year follow-up showed satisfactory results. Laser treatment is considered one of the alternatives to conventional treatment, but the surgeon needs to be aware of laser hazards.

Villous adenoma of the appendix is a rare neoplasm and intussusception of the appendix is a rare pathologic condition. A very rare case seen in a 35-year-old male with pain in the right lateral abdomen is reported. In this patient, the appendix along with the villous adenoma intussuscepted and invaginated into the cecal lumen, and presented as cecocolic intussusception. A polypoid lesion was diagnosed in the cecum by fiberoptic colonoscopy. Unlike polypoid lesions at other sites in the large intestine, polypoid lesions of the cecum may accompany intussusception and invagination of the appendix. Consequently, caution is required in performing endoscopic polypectomy in cases of polypoid lesions of the cecum.

In a 10-year experience with 4,784 consecutive colonoscopic polypectomies, the need for operative intervention in just two of seven perforations indicates that patients with specially defined, limited perforations can usually be treated nonoperatively. This specific complication, which has been termed "mini-perforation," is generally detected within 6-24 hours of polypectomy, and is characterized by local pain and tenderness, without signs of diffuse or spreading peritoneal irritation. Free intra-abdominal or retroperitoneal air on x-ray documents the actual perforation. Complete resolution of symptoms within 24-48 hours confirms the diagnosis of "mini-perforation." Success depends on good bowel preparation for colonoscopy, and early recognition of perforation, with institution of bowel rest and intravenous antibiotics. The "mini-perforation" spontaneously closes, probably by omental adherence. Frequent serial clinical examinations are mandatory so that frank perforation with advancing peritonitis will be promptly recognized and treated surgically. An understanding of the three levels of cautery injury to the colon wall--"serosal burn," "mini-perforation," and "frank perforation" are essential in managing the complications of colonoscopic polypectomy.

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.

We retrospectively reviewed six patients with squamous cell carcinoma of the anus (SCCA) and human immunodeficiency virus (HIV) infection treated between 1985 and 1988. All six patients were homosexual men. Five patients had AIDS and one was HIV-positive. The most common symptoms and signs were pain (n = 5), mass (n = 5), and bleeding (n = 5). The average tumor size was 3.2 cm with a range of 1-10 cm. Five tumors were located in the anal canal and one at the anodermal junction. One patient was treated with biopsy alone, one with local excision, one with wide local excision and radiation therapy, and two with diverting colostomy. The average follow-up was 8 months. Of the five AIDS patients, two died, one was transferred to a hospice facility, one was lost to follow-up, and one remains alive 1 year following treatment. The HIV-positive patient died secondary to metastatic SCCA. This group of patients raises the question of a possible association between HIV and SCCA.
