The rodless, end-loop stoma was developed as an alternative to the more traditional loop stoma to minimize patient management problems. A retrospective review of our seven-year experience in 229 patients with end-loop colostomies (135), ileocolostomies (70), and ileostomies (24) is presented. A total of 30 stoma-related complications were observed in 27 stomas, for an overall complication rate of 13.1 percent. The most common complications were skin excoriation secondary to leakage (3.5 percent), retraction (3.5 percent), partial necrosis (2.6 percent), and peristomal sepsis (1.8 percent). Mucocutaneous separation,
prolapse
, and stenosis were each seen in less than one percent of patients. No cases of stomal herniation, obstruction, or hemorrhage were encountered. Twelve deaths occurred, but none was attributed to stoma-related complications. The rodless, end-loop stoma is a simple and safe procedure with many advantages and a low incidence of complications.

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.

Two hundred eight patients with retention disorders have been studied. Most frequent causes were idiopathic (107), iatrogenic (57), and obstetric (33). Twenty-five patients experienced soiling, 31 had insufficient function, and 152 complained of incontinence. Seventy percent of patients with idiopathic incontinence did not experience urge, compared with 38 percent with iatrogenic and only 3 percent with obstetric incontinence. The incidence of
prolapse
was 58 percent in patients with idiopathic incontinence, 20 percent in patients with iatrogenic incontinence, and only 3 percent in patients with obstetric incontinence. The authors conclude that the function of the puborectalis sling is to create the anorectal angle to evoke the feeling of urge and to support intra-abdominal contents and, furthermore, that fecal incontinence after anorectal surgery was likely caused by denervation. Anal resting and squeeze pressures varied widely. There was a huge overlap in the different groups. Mean resting and squeeze pressures were 9.5 kPa and 9.4 kPa, respectively, in controls, 4.8 kPa and 10.3 kPa, respectively, in the soiling group, 7.1 and 6.1 kPa, respectively, in the insufficient group, and 5.1 and 2.7 kPa, respectively, in the incontinent group. An incontinent external sphincter function could be defined as a function of the external sphincter causing a pressure increase of 5 kPa or less during straining. The ability to retain feces, therefore, is based on external sphincter function. Anal manometry is, indeed, a suitable technique to determine anal sphincter functions, but the presence of a retention disorder cannot definitely be determined. Its clinical application remains under discussion.

Bowel habit in 57 rectal prolapse patients was assessed before and after abdominal Ivalon rectopexy. There was a significant (chi-square = 8.7, P less than 0.01) increase in prevalence of constipation from 30 percent before to 51 percent after surgery. There were two explanations for this increased constipation. It was mainly the result of a 28 percent increase in prevalence of constipation among patients who were incontinent before rectopexy. Incontinent
prolapse
patients were more likely to acquire a predictable bowel habit after rectopexy if they became constipated. There was also a small (7 percent) increase in prevalence of constipation among continent patients, which could be attributed to the rectopexy procedure. In a subgroup of 15 patients, rectal wall thickness after rectopexy was assessed by pelvic computed tomographic scan carried out before and after surgery, or at more than one year after surgery. There was a significant (t = 4.5, P less than 0.001) increase in rectal wall thickness by 24 weeks after rectopexy, compared with before operation. This increase was also seen in a further five patients undergoing abdominal rectopexy without Ivalon sponge, suggesting that it was a consequence of rectal mobilization rather than the Ivalon sponge. This increased rectal wall thickness may impede the passage of formed stool into the lower rectum and contribute to the increased constipation found after rectopexy.

Eighteen patients with severe constipation after undergoing the Ripstein operation for rectal prolapse (n = 11) or internal rectal
procidentia
(n = 7) were studied with defecography, anorectal manometry, electromyography of the external anal sphincter and the puborectalis muscle, colonic transit time, and blood tests. Thirteen patients had slow-transit constipation. None showed a completely normal pattern in the parameters studied. The authors emphasize the importance of careful preoperative investigation to identify the patients who have associated colorectal disturbances together with their rectal prolapse or internal rectal
procidentia
.

Perineal approaches for rectal prolapse are particularly useful in high-risk patients or in patients presenting with strangulation. Each technique is useful in certain clinical situations. Altemeier's procedure, with the addition of rectopexy and levatorplasty (Dis Colon
Rectum
29: 547-552, 1986) may be the best available perineal operation for long-term correction of
prolapse
and treatment of associated incontinence.

Rubber band ligation was used in 160 patients with internal hemorrhoids; 43 of them also had rectal anterior mucosal
prolapse
; 13 had
prolapse
alone. Two thirds of the patients underwent a single rubber band ligation and one third a double rubber band ligation in one session without anesthesia. Ninety-four required repeated ligations. A follow-up of 25 +/- 16 months (mean +/- SD) was carried out in 153 of them. Rubber band ligation was followed by prolonged bleeding in six patients and severe pain requiring removal of the rubber band in 12 patients. The complication rate decreased significantly (P less than .05) in the last 80 patients. Compared with multiple ligation, single rubber band ligation in one sitting was followed by a lower complication rate (P less than .01). Long-term results were good in 71 percent of the patients. (A formal hemorrhoidectomy was needed within two years in 6 percent.) A significantly lower recurrence rate of 9 percent was noted in those with normal bowel habits, when compared with constipated subjects whose symptoms recurred in 85 percent (P less than .001). Constipation seems to be a predictable factor in worsening the outcome of rubber band ligation. Rubber band ligation is followed by a lower complication rate when performed in a single ligation.

One hundred sixty-five cases of abdominal rectopexy using polypropylene (Marlex) mesh for rectal prolapse were reviewed. Six patients were men and 159 were women. Thirty patients have not been evaluated after surgery, 22 having died of interrecurrent disease and 8 have had their surgery during the last two months. Incontinence was observed in 95 patients (58 per cent) before surgery, whereas it persisted in only 21 of 135 patients (16 percent) after surgery. Forty patients (24 percent) claimed constipation before surgery, whereas 60 of 135 patients (44 percent) had constipation after rectopexy. Recurrence of full-thickness rectal prolapse was found in only 2 patients-(1.5 percent). Mucosal
prolapse
occurred in 9 patients (7 percent) after surgery. These results indicate that abdominal posterior rectopexy using Marlex mesh is an effective operation for rectal prolapse, but persistent incontinence occurs in one third of patients and almost half become constipated after the procedure.

In an attempt to evaluate the real efficacy of loop colostomy for fecal diversion, the authors studied 62 patients previously colostomized under emergency conditions. Radiologic series of the abdomen were taken after 200 gm of barium meal. The results showed that the colostomy provided complete diversion of the radiologic contrast in 53 patients (85 percent) and incomplete diversion in nine patients (15 percent). Analysis of the results revealed that incomplete fecal diversion was: 1) observed as of the 86th postoperative day, with a significantly higher frequency following the 10th postoperative month, and 2) significantly correlated with either colostomy retraction or
prolapse
. The authors present a diagram showing a possible interaction of factors responsible for incomplete fecal diversion in loop colostomy and conclude that: 1) retraction is probably the basic contributing factor for colostomy failure; 2) the
prolapse
, once reduced, propitiates sinking of the stoma, facilitating colostomy failure; 3) the common assumption that loop colostomy eventually fails to provide complete fecal diversion is further supported; 4) loop colostomy assures, over its usual duration, a satisfactory defunctionalization of the colon; and 5) use of improved techniques of colostomy construction may prolong complete fecal diversion.
