Incontinence and rectal prolapse: a prospective manometric study.

A prospective, manometric study has been performed on 23 female patients with rectal prolapse and varying degrees of incontinence. Seven of the 14 incontinent patients regained continence after surgery, and a further two patients improved. Improvement in internal and external sphincter function follows correction of rectal prolapse. Preoperative resting anal pressure was significantly higher in continent patients than in incontinent patients (P less than 0.05), as was the maximum voluntary contraction pressure (P less than 0.027). Postoperatively there was a significant increase in the resting anal pressure (P less than 0.0001) and maximum voluntary contraction pressure (P less than 0.003) in the whole group. The preoperative resting anorectal angle was significantly more acute (P less than 0.028) in continent patients than in incontinent patients. There was no significant change in the resting anorectal angle following prolapse repair. Patients who remained incontinent had a significantly lower preoperative resting anal pressure (P less than 0.01) than patients who improved or regained continence. Similarly, maximum voluntary contraction pressure was lower preoperatively in these patients (P less than 0.02). Preoperative resting anal pressure below 10 mm Hg and maximum voluntary contraction pressure below 50 mm Hg are associated with persisting incontinence after surgery.

Rectal compliance: a critical reappraisal.

Compliance is a widely measured parameter of rectal function. Its value is determined clinically by recording pressure changes associated with volume infusion into a rectal balloon. This paper examines the inherent assumptions of the rectal balloon technique and discusses several of its shortcomings. A stricter definition of rectal compliance is needed, and in vivo compliance should be correlated with the directly measured mechanical properties of the rectal wall.

Endorectal ultrasound in the preoperative staging of rectal tumors. A learning experience.

The preoperative staging of rectal cancer has important implications for treatment as local therapies become increasingly utilized. Seventy-seven patients underwent preoperative staging using endorectal ultrasonography. All patients had complete pathologic staging and none had preoperative radiotherapy. Depth of invasion of the tumor was accurately predicted in 75 percent of cases in the entire group, with 22 percent overstaged and 3 percent understaged. Accuracy improved greatly over the study period, and in the past six months, 95 percent have been accurately staged for depth of invasion with 5 percent overstaged. Lymph nodes have been properly classified into positive and negative groups in 88 percent of cases in the past year, with a specificity of 90 percent and a sensitivity of 88 percent. Endorectal ultrasound is an accurate preoperative staging modality. Accuracy is improved greatly with increased experience and it has been found that the 5-layer anatomical model facilitates accurate staging. Introduction of the ultrasound probe through a previously placed proctoscope ensures complete scanning of the entire lesion and should be used for the majority of examinations.

The ileoanal reservoir.

One hundred nine men and 71 women with a mean age of 31 years had construction of 164 S, 2 J, and 14 other ileoanal reservoirs. Postoperative gastrointestinal complications included small bowel obstruction in 11 percent and ileus, hemorrhage, and sepsis in 6 percent, 5 percent, and 11 percent, respectively. There was a 13 percent incidence of miscellaneous postoperative complications. Pouch perianal fistulas developed in 5 percent of patients, and pouch vaginal and other pouch fistulas developed in an additional 4 percent. During long-term follow-up, small bowel obstruction developed in 27 percent of patients, and enterolysis or enterectomy was required in 15 percent of patients. One hundred fourteen patients who were followed for a mean length of 5 years after ileostomy closure (range 16 to 88 months) were evaluated for functional outcome. Function improved with time in 63 percent of patients and remained stable in another 33 percent; only 4 percent had long-term deterioration. Ninety-five percent of patients would again choose an ileoanal reservoir over a permanent ileostomy. This long-term assessment shows that although the ileoanal reservoir is a viable option in the management of mucosal ulcerative colitis, it should not be recommended to every patient.

Long-term functional analysis of the ileoanal reservoir.

Since November 1980, 180 patients underwent abdominal colectomy, rectal mucosectomy, ileoanal reservoir construction, and ileoanal anastomosis at the authors' institutions. One hundred twenty-nine patients had restoration of intestinal continuity before the end of 1986. One hundred fourteen of these patients (88 percent) were available for follow-up at a mean length of time of 5.0 years from ileostomy closure (range, 16 to 88 months). The mean number of pouch evacuations was 5.4 +/- 2.5 during the day (range, 1 to 12) and 1.5 +/- 1.0 at night (range, 0 to 6). Ninety-one percent of patients reported perfect or almost perfect daytime continence, and 74 percent found this true at night. Sixty-three percent of patients believed their pouch function continued to improve over many years. Ninety-five percent of patients questioned would choose an ileoanal reservoir again instead of a permanent ileostomy. This long-term assessment of the function of the ileoanal reservoir confirms that it is a viable, although not perfect, option in the management of ulcerative colitis and familial adenomatous polyposis.

Ileal pouch vaginal fistulas: incidence, etiology, and management.

Some of the initial problems associated with the ileoanal reservoir have been solved. In their place, other complications have been recognized. Among these, the ileal pouch vaginal fistula stands out as a recently recognized difficult management problem. This multicenter study was undertaken to gain insight into the causes for, and treatment of, pouch vaginal fistulas. Cases were gathered from 11 surgical practices throughout North America, in which the ileoanal reservoir procedure is frequently performed. Overall, 304 females had undergone ileoanal reservoir procedures by these surgical groups. Twenty-one patients developed 22 pouch vaginal fistulas for an overall incidence of 6.9 percent. Five additional patients with pouch vaginal fistulas, whose restorative proctocolectomies were done elsewhere, were referred to these surgeons for treatment. The courses of these 26 patients form the basis of this report. This study details the risk factors which predispose in the development of a pouch vaginal fistula, as well as the various treatment options available.

Synchronous bowel anastomoses.

A retrospective review of patients who underwent double bowel resections and synchronous anastomoses without ileostomy or colostomy was undertaken. The study goal was to determine whether there was an increased incidence of complications attributable to the presence of a second anastomosis. A total of 66 patients who met the criteria were identified and divided into two groups. Group A consisted of 30 patients who had had two colonic resections and two colonic anastomoses. In Group B were 36 patients who had undergone separate colonic and small-bowel resections with two subsequent anastomoses. The indications for primary resection were: 1) adenocarcinoma, 54 percent; 2) Crohn's disease, 26 percent; 3) diverticulitis, 11 percent; 4) "other" indications, 9 percent. The indications for the second resection were: 1) metastatic adenocarcinoma, 30 percent; 2) Crohn's disease, 26 percent; 3) synchronous bowel lesions, 18 percent; 4) adhesions and enterotomies, 14 percent; 5) "other" indications, 12 percent. Overall, there were four major complications (6 percent), and 11 minor complications (17 percent). The sole anastomotic leak occurred in a patient who had undergone a double colonic resection (3%). The other major complications were one death, one ureteral complication that required reoperation, and one early small-bowel obstruction. Minor complications included two wound infections (3 percent), three seromas (5 percent), three prolonged ileus (5 percent), and three urinary infections (5 percent). These results are comparable to the best results reported for patients undergoing single colonic anastomoses. The conclusion is that it is safe to perform synchronous anastomoses without diversion provided the following conditions are present: well-prepared bowel with minimal fecal soilage, an adequate blood supply, technically good anastomoses, and lack of tension on the suture lines.

Local excision for selected colorectal carcinomas.

In summary, local excision is a useful tool in the management of selected colorectal carcinomas. The advent of the fibreoptic colonoscope has revised the concept of local excision when dealing with carcinoma-containing polyps of the colon. The clinician now has the means of locally excising certain carcinomas which would have required laparotomy in the not so distant past. In dealing with carcinoma of the rectum, local excision is not advocated for all rectal carcinomas. In fact, when the previously discussed tumour related factors are considered, local excision should be the ultimate procedure in less than 5% of operations performed for rectal carcinomas. However, when appropriately used, local excision provides a less morbid alternative to more radical procedures without compromising patient survival rates or local recurrence rates.

Colonic resection in the treatment of complete rectal prolapse.

For the good risk patient, nearly all surgeons recommend an abdominal approach as the surest method of eliminating a complete rectal prolapse. The most commonly performed abdominal procedures are rectal suspension-fixation operations utilizing slings of synthetic material or suture without foreign material. Occasionally both of these procedures are combined with a segmental colorectal resection. Rectal mobilization with fixation of the rectum to the sacrum alone, by whatever means, has a high rate of success with a low mortality and morbidity. The wisdom of adding colorectal resection to rectopexy in the treatment of complete rectal prolapse remains controversial. The authors favor abdominal rectopexy with sigmoid resection because it avoids foreign material, eliminates the risk of volvulus, improves bowel management problems, and has low morbidity with a low recurrence rate. In our series of 102 patients treated by rectopexy and sigmoid resection, there were no deaths and only 4 per cent morbidity related to the anastomosis. After a mean follow-up period of four years, the recurrence rate was 1.9 per cent.

Intra-operative endoscopy. University of Minnesota experience.

This review of intraoperative endoscopies was undertaken to identify the accepted and the controversial indications, to report the results and complications, and to determine the impact the procedure had on the operation performed. This retrospective review identified 78 patients who had undergone 82 intraoperative endoscopic exams between 1981 and 1987. Sixty-nine patients underwent intraoperative colonoscopy (84%), six had upper enteroscopy (7%), and seven had total gut endoscopy (9%). Indications were as follows: the inability to fully colonoscope preoperatively (29%), Crohn's disease (19%), malignant polypectomy site (12%), gastrointestinal bleeding (12%), routine screening to rule out synchronous lesions (12%), non palpable colonic lesions (11%), and miscellaneous (4%). Intraoperative endoscopy was successful in 89 per cent of patients. The exams provided information that altered the planned operation in 27 per cent of cases. There were four complications that may have been related to the endoscopic exams. All resolved without the need for further surgery. It is concluded that intraoperative endoscopy can greatly influence the operation performed in a significant percentage of cases. The clear cut indications for its use at this time are location of malignant polypectomy sites, adhesions or tortuous colon that prevents complete preoperative colonoscopy, chronic gastrointestinal bleeding, and location of non palpable bowel lesions. Controversial indications that we feel will prove useful include Crohn's disease and acute gastrointestinal bleeding. Intraoperative endoscopy is best used as an adjunct to preoperative endoscopy and not as a substitute for it.

Repair of simple rectovaginal fistulas. Influence of previous repairs.

The results of 81 endorectal flap advancements for simple rectovaginal fistulas are reported. Simple fistulas are defined as less than 2.5 cm in diameter, low or mid vaginal septum in location, and infectious or traumatic in origin. Essentially, the technique is advancement of a flap of mucosa, submucosa, and circular muscle over midline approximation of internal sphincter muscle. The mean patient age was 34 years old (range, 18 to 76 years). The causes were obstetrical injury (74 percent), perineal infection (10 percent), operative trauma (7 percent), and unknown (8 percent). Overall, the repair was successful in 83 percent of patients. Success correlated with the number of previous repairs, i.e., none: 88 percent success; one: 85 percent success; two: 55 percent success. There were 25 concomitant overlapping sphincteroplasty procedures. Only minor complications ensued, with no mortality. This repair is recommended for patients with no or one previous repair because of its lack of mortality, minimal morbidity, ease of concomitant sphincteroplasty, and avoidance of a colostomy. For patients with two or more earlier repairs, a muscle interposition should be considered.

Is subtotal colectomy a viable option in the management of chronic constipation?

To determine if subtotal colectomy constitutes a valuable alternative in the treatment of patients with chronic constipation, a retrospective review of 52 consecutive patients who underwent subtotal colectomy between January 1980 and August 1985 was undertaken. Forty-six patients underwent ileodistal sigmoidostomy while five patients underwent ileoproctostomy and five with concomitant rectal prolapse underwent simultaneous proctopexy. A mortality rate of 3.8 percent and morbidity rate of 60 percent were encountered. The most frequently occurring complication was small-bowel obstruction, which occurred in 36 percent, and necessitated laparotomy in 66 percent. Additional procedures were necessary in five patients because of newly discovered rectal prolapse (two patients), rectocele (one patient), unrelieved constipation (one patient), and incapacitating incontinence (one patient). Follow-up data available in 94 percent (mean, 46 months) disclosed that patients had an average of 2.8 bowel movements per day without the use of laxatives (89 percent) or enemas (80 percent). Overall, 79 percent were satisfied with the final outcome. It is concluded that subtotal colectomy constitutes a viable option in the treatment of chronic constipation. However, the significant morbidity and mortality associated with the procedure dictate the need for careful patient selection on the basis of appropriate physiologic testing.

Palliation for rectal cancer. Resection? Anastomosis?

There is no agreement regarding the proper management of patients with advanced carcinoma of the rectum. We performed a study to clarify whether palliative resection with or without primary anastomosis is worthwhile and safe. Among 679 patients managed for cancer of the rectum, 125 were considered incurable and underwent palliative procedures. High and low anterior resections were performed in nine and 57 cases, respectively, abdominoperineal resection in 26, Hartmann's procedure in three, simple diverting colostomy in 17, and transanal excision in 13. The overall postoperative mortality rate was 0.8%. Postoperative morbidity was 18% in abdominal operations and none in local excisions. Among patients treated by abdominal resections, only one required subsequent reoperation for colonic obstruction secondary to local recurrence. The median survival was 6.4 months for patients treated by diverting colostomy, 14.8 months for abdominally resected cases, and 14.7 months for transanal excisions. We conclude that palliative resection, often with primary anastomosis or local transanal excision, can be done safely in patients with incurable rectal cancer. We believe this approach improves the quality of the remaining life for these patients.

Proctocolectomy and ileoanal anastomosis with an S pouch: functional results.

Patients with total colonic ulcerative colitis or familial polyposis traditionally require a proctocolectomy. In an effort to preserve the normal pathway for defecation and avoid the nuisance of an abdominal stoma, a continence-preserving procedure involving a pelvic reservoir has been performed at the University of Minnesota Hospitals on 120 patients. The majority were operated on for colonic ulcerative colitis. There were no deaths. The mean hospital stay after restorative proctocolectomy was 10 days and after ileostomy takedown the mean stay was 7 days. Functional results were assessed in 52 patients. Daytime bowel movements averaged 6.4 and night-time movements 1.4. Major daytime incontinence occurred in 6% of the patients, 21% had moderate soiling at night and 70% wore a perineal pad in the evening. Ninety-two percent of the patients expressed satisfaction with the procedure. The most serious complication was pelvic sepsis. It occurred in nine patients, six of whom required subsequent surgery. The Parks S pouch provides a means of maintaining anal continence. This series and others have shown that young, healthy, well-motivated persons will benefit most from a restorative proctocolectomy.
