Delorme's procedure for complete rectal prolapse in severely debilitated patients

PURPOSE: This study was designed to assess the results of a minimally invasive surgical procedure for the correction of complete rectal prolapse in a poor surgical risk group. METHODS: Over a ten-year period, 40 patients underwent 41 Delorme operations when advanced age and/or poor overall health mitigated against an abdominal approach. Mean age was 82 (range, 30–100) years. Eighty-eight percent were females. Surgery was performed in the prone jackknife position utilizing intravenous sedation and local anesthesia. RESULTS: Follow-up ranges from 1 year to 2 years (mean, 47 months). There have been 9 recurrences in 8 patients (22 percent). Mean time to recurrence was 13 months (range, 1 month to 6 years). One death occurred in an 81-year-old patient within 24 hours of surgery from cardiopulmonary arrest. Minor complications occurred in 25 percent of patients. CONCLUSION: Satisfactory prolapse repair was safely performed in 78 percent of this high-risk group. Pitfalls in performing this procedure relate primarily to associated perineal and colonic conditions. Most prominent among these conditions are weak or absent anal sphincter tone, perineal descent, and previous sphincter injury. Extensive diverticular disease may prohibit effective and complete proximal mucosectomy. An inadequate mucosectomy sets the stage for early recurrence of prolapse.     

Ripstein procedure is an effective treatment for rectal prolapse without constipation

The operation of choice for complete rectal prolapse is controversial. We reviewed 169 patients undergoing 185 surgical procedures for rectal prolapse over a 27-year period. The most common surgical procedure employed was the Ripstein procedure (n=142) and is the focus of this report. Other surgical procedures used included resection rectopexy (n=18), anterior resection (n=7), Altemeier's (n=9), Delorme's (n=2), and anal encirclement (n=7). The median age was 59 years (range, 12–94 years), and the female-to-male ratio was 51. The incidence of fecal incontinence, solitary rectal ulcer syndrome, and prior surgery elsewhere for rectal prolapse was 40 percent, 12 percent, and 19 percent, respectively. Operative mortality was 0.6 percent; morbidity was 16 percent. Median follow-up was 4.2 years (range, 1–15 years). Complete recurrence of prolapse after the Ripstein procedure was 8 percent; one-third of these patients recurred 3 to 14 years after surgery. Fecal incontinence improved after the Ripstein procedure or resection rectopexy in about half the patients. Persistence of prior constipation was more common after the Ripstein procedure than after resection rectopexy (57 percent vs. 17 percent;P=0.03, chi-squared). Fifteen patients developed constipation for the first time after the Ripstein procedure. About one in three patients, irrespective of surgical procedures, remained dissatisfied with the final outcome despite anatomic correction of the prolapse. The Ripstein procedure has proven to be a safe procedure with good anatomic repair of the prolapse and may improve continence. In the presence of constipation, procedures other than the Ripstein procedure may be preferable.Read in part at the meeting of The American Society of Colon and Rectal Surgeons, San Francisco, California, June 7 to 12, 1992.     

Results of Delorme's procedure for rectal prolapse

PURPOSE: This study was designed to examine the results of Delorme's procedure. METHODS: Thirty-two patients (24 males and 8 females, mean age, 70 years) underwent Delorme's procedure between 1978 and 1990 following symptoms lasting between two weeks and ten years. Thirteen patients had had 21 previous operations for prolapse. RESULTS: The mean operation time was 65 minutes. No blood transfusions were needed, there was no operative mortality, and only two patients had complications (one chest infection and one anastomotic dehiscence). No patients were lost to follow-up. Over a mean follow-up of 24 months (4 months to 4 years), 9 patients died of unrelated conditions. There were four recurrences (12.5 percent), two in patients who had each had two previous procedures. Incontinence improved in 46 percent. No patient became constipated and 50 percent of those constipated preoperatively improved. CONCLUSION: Although abdominal rectopexy is safe and has a low recurrence rate (<5 percent), it involves the hazards of a laparotomy. In addition, up to 40 percent of patients become constipated after rectopexy which may be debilitating. Delorme's procedure has a low morbidity, results in good bowel function, and has a low recurrence rate. It can be performed on unfit patients with possible advantages over rectopexy and perhaps should be used more readily.     

Results of Delorme's procedure for rectal prolapse

PURPOSE: A retrospective study was undertaken to assess the results of Delorme's procedure for rectal prolapse and to determine the advantages of an innovative extended transrectal repair, which aims at performing a total pelvic floor repair. METHODS: A total of 85 patients, ranging in age from 21 to 97 years, were operated on. Sixty-five (82 percent) patients had varying degrees of fecal incontinence. Similar groups of patients were compared with regard to control of the prolapse and restoration of continence according to 1) age and medical condition and 2) operative technique: original vs.extended operation. RESULTS: Twelve patients (14 percent) developed postoperative complications. There was one perioperative death (1.2 percent). Eighty patients were followed for 6 to 136 (median, 33) months. Eleven (13.5 percent) developed recurrent full-thickness prolapse. The recurrence rate was significantly different 1) between 44 elderly and poor operative risk patients not suitable for abdominal surgery (22.5 percent) and 41 younger patients without concurrent medical conditions, electively submitted to perineal repair (5 percent) (P <0.05), and 2) between the original procedure (21 percent of 44 patients) and the modified technique (5 percent of 41 patients) (P <0.05). Forty five patients (69 percent) improved or regained full continence. No patient worsened. No residual dysfunction was induced. Restoration of continence was not influenced by selection of patients or surgical technique. CONCLUSIONS: Despite increased morbidity (22 percent; P <0.05), advantages of the modified technique were 1) over the original procedure, a reduced recurrence rate, 2) over perineal proctectomy, the absence of coloanal anastomosis and better functional outcome, and 3) over abdominal rectopexy, a less aggressive approach without disturbing effects on bowel habits.     

Abdominal rectopexy for rectal prolapse

PURPOSE: The aim of this study was to investigate the influence of surgical technique on functional and manovolumetric results in patients treated with Marlex^® mesh abdominal rectopexy. METHODS: The lateral ligaments were completely divided (the Wells procedure) in 16 patients and preserved (the Ripstein procedure) in 16 patients. Clinical and physiologic assessment were performed before and at 3, 6, and 12 months after operation. RESULTS: Improvement of continence was similar. Bowel regulation problems which were unchanged after the Ripstein procedure increased significantly after the Wells procedure (P<0.01). Rectal volume became reduced in the group who received the Wells procedure (225 mlvs. 115 ml, P<0.05 at one year), but remained unchanged after receiving the Ripstein procedure. The pressure thresholds required to elicit sensation of rectal filling and defecation urge were increased after the Wells procedure (15 cm of H₂Ovs. 25 cm of H₂O, P<0.05 and 25 cm of H₂O vs. 45 cm of H₂O, P<0.05, respectively). In the Ripstein group there was only a slight increase of the threshold for urge (P<0.05). CONCLUSION: The Wells procedure was followed by severe rectal dysfunction accompanied by increased constipation and evacuation problems. The Ripstein procedure, preserving the lateral ligaments, appears not to affect such symptoms adversely. On the other hand, improvement is not likely to occur.Supported by grants from the Swedish Medical Research Council (17X-03117), University of Gothenburg, Gothenburg Medical Society, and Assar Gabrielsson's Fund.     

Abdominal rectopexy for complete prolapse: Prospective study evaluating changes in symptoms and anorectal function

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 (<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 postoperatively. 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.Support for this study was received from the Imperial Cancer Research Fund, ICI Pharmaceuticals (SA) Ltd., the St. Mark's Research Foundation, and the Medical Research Council of South Africa.     

Clinical and pathologic factors associated with delayed diagnosis in solitary rectal ulcer syndrome

Solitary rectal ulcer syndrome (SRUS) often goes unrecognized or is misdiagnosed. Of 98 patients with a final clinicopathologic diagnosis of SRUS, an initially incorrect diagnosis had been made in 25 patients (26 percent). In these 25 patients with a misdiagnosis, the median age was 43 years and the female-to-male ratio was 3.21. The median duration of incorrect diagnosis was five years (range, three months to 30 years), and seven patients received prednisone (>30 mg/day) for a mistaken diagnosis of inflammatory bowel disease. The main clinical symptoms were rectal bleeding (84 percent) and a disturbance of bowel function (56 percent). Rectal prolapse was present in 13 patients. Original rectal biopsy specimens from 23 patients were reviewed; inadequate specimens and failure to recognize diagnostic features of SRUS contributed to delayed diagnosis in 13 and 10 patients, respectively. The most common clinicopathologic mis-diagnoses in SRUS patients with rectal ulcers or mucosal hyperemia were Crohn's disease and mucosal ulcerative colitis. In patients with polypoid SRUS, diagnostic confusion was usually with a neoplastic polyp. Persistent bowel symptoms and rectal lesions led to review of the presentations and repeat biopsy directed toward the edge of the rectal ulcers or from within the polypoid or hyperemic rectal lesions, finally establishing the diagnosis of SRUS. Intractable symptoms led to surgery in 15 patients (60 percent), with symptomatic improvement in over two-thirds.     

Long-term results of suture rectopexy in patients with fecal incontinence associated with incomplete rectal prolapse

Suture rectopexy is the recommended therapy for complete rectal prolapse that is associated with fecal incontinence. It has been suggested that correction of an incomplete rectal prolapse is also worthwhile for patients with fecal incontinence. PURPOSE: Aims of this study were 1) to evaluate the clinical outcome of suture rectopexy in a consecutive series of patients with incomplete rectal prolapse associated with fecal incontinence, and 2) to compare these results with those obtained from patients with complete rectal prolapse. METHODS: Between 1979 and 1994, suture rectopexy was performed in 13 incontinent patients (3 males; median age, 65 (range, 45–77) years) with incomplete rectal prolapse (Group I) and in 24 incontinent patients (21 females; median age, 71 (range, 24–86) years) with complete rectal prolapse (Group II). RESULTS: After a median follow-up of 67 months, continence was restored in 5 of 13 (38 percent) patients with incomplete rectal prolapse and in 16 of 24 (67 percent) patients with complete rectal prolapse. In both groups, all male patients became continent. CONCLUSIONS: For the majority of incontinent patients with incomplete rectal prolapse, a suture rectopexy is not beneficial. The clinical outcome of this procedure is only good in incontinent patients with complete rectal prolapse. Based on these data, it is questionable whether incomplete rectal prolapse plays a causative role in fecal incontinence.Read at the meeting of the International Society of University Colon and Rectal Surgeons, Lisboa, Portugal, April 14 to 18, 1996.No reprints are available.     

Anal encirclement with polypropylene mesh for rectal prolapse and incontinence

Seventeen selected patients (mean age, 74 years)—14 with rectal prolapse and 3 with persisting anal incontinence after previous operations—underwent high anal encirclement with polypropylene mesh. There was no operative mortality. Prolapse recurred in 2 (15 percent) of the 13 patients followed up for 6 months or more (mean, 3.5 years). Three (27 percent) of the 11 patients with associated anal incontinence improved functionally, as did the three operated on for persisting incontinence, but only one patient regained normal continence. No breakage, cutting out, or infection related to the mesh was observed. Because of the risk of fecal impaction encountered in three of our patients, the procedure is not advocated for severely constipated patients. Despite the somewhat disappointing results regarding restoration of continence, we find this method useful in patients with rectal prolapse who are unfit for more extensive surgery, in controlling the prolapse to an acceptable degree.     

Biofeedback therapy in rectal prolapse patients

PURPOSE: The aim of the study was to evaluate the effect of perioperative biofeedback training on postoperative continence in patients with rectal prolapse. METHODS: Thirtysix consecutive patients were operated on between 1987 and 1993. Twenty-nine could be traced for reexamination. Four were excluded because of a recurring prolapse. Anal manometry, assessment of rectoanal sensation, and surface electromyography were performed during the reexamination. From 1987 to 1991, no perioperative biofeedback training was given (Group 1, n=14). Since the beginning of 1992, incontinent patients were given biofeedback training (Group 2, n=11). RESULTS: Continence scores improved in both study groups. Both study groups had equally low resting pressures compared with Group 3 (controls) (30.6±1 4.9 vs.53.0±11.9 mmHg;P <0.001). Anal resting pressure correlated with postoperative continence score, whereas contractile pressures did not ( r =–0.5,P < 0.05, and r =–0.3,P =not significant, respectively). CONCLUSION: Biofeedback therapy can improve the function of external sphincter; however, the most important reason for postoperative incontinence in rectal prolapse patients is low resting pressure that cannot be corrected by biofeedback therapy.Supported by grants from the Central Finland Health Care District.     

Sucralfate retention enemas in solitary rectal ulcer

The conservative treatment of solitary rectal ulcer is generally unsatisfactory. Six patients, aged 27–54 years, with recurrent solitary rectal ulcer were treated with topical administration of sucralfate in a daily dose of 2 g twice a day for 6 weeks. Four patients experienced complete relief of symptoms and the remaining two patients had marked improvement. Although macroscopic healing of the ulcer was apparent in all, histologic improvement was not appreciable. Five of the six patients remain in remission during a follow-up period of 4–14 months (mean, 8±1.5 months). Recurrence was observed in one patient at 5 months, which satisfactorily resolved with sucralfate enemas. From these preliminary observations we infer that solitary rectal ulcer can be effectively treated with topical application of sucralfate.     

Management of acute incarcerated rectal prolapse

Perineal excision was used to treat eight elderly patients with acute incarcerated prolapse: four showed signs of strangulation with areas of gangrene, six made an uneventful recovery without colostomy, and two developed anastomotic leak, needing diverting colostomy with a complete recovery. There were no mortalities. There were no recurrences of rectal prolapse.Read at the meeting of The American Society of Colon and Rectal Surgeons, St. Louis, Missouri, April 29 to May 4, 1990.     

Internal rectal intussusception—Fact or fancy?

PURPOSE: There is still considerable debate whether internal intussusception represents a functional disorder. We have reviewed our results in an effort to define its symptomatology and to assess defecography. METHODS: Rectopexy has been performed for internal intussusception in 37 patients. Eighteen had solitary rectal ulcer syndrome (SRUS), and 31 had anterior rectal wall prolapse. Defecography demonstrated anterior wall prolapse in 13, circular prolapse in 21, and no disorders in 3 patients. Pelvic floor function was normal. Follow-up varied from one to nine years. RESULTS: Twenty-six patients became asymptomatic. Anterior wall prolapses could not be palpated anymore. All SRUS lesions healed. Patients with SRUS (P<0.001) or circular prolapse (P<0.001) became significantly more asymptomatic. Results in patients with anterior rectal wall prolapse were significantly worse (P<0.001). CONCLUSIONS: Internal intussusception is a distinct functional rectal disorder. Its symptomatology and findings during physical examination are aspecific. Characteristic defecographic features and presence of SRUS are indications for surgery, provided pelvic floor function during straining is normal.     

Enterocele is correctable using the Ripstein rectopexy

PURPOSE: About one-third of the patients with rectal prolapse or rectal intussusception have concurrent enterocele at defecography. The purpose of this study was to evaluate the effect of the Ripstein procedure on the concurrent enterocele and to study the outcome of the procedure with respect to the patients' symptoms. METHODS: Twenty-two patients with enterocele and either rectal prolapse or rectal intussusception at defecography were treated using the Ripstein procedure. Postoperatively, the patients were evaluated with clinical examination (22 patients) and defecography (16 patients). RESULTS: None of the patients had recurrence of enterocele, rectal prolapse, or intussusception at postoperative follow-up. Continence was improved in 15 of 16 incontinent patients. Emptying difficulties were unchanged in eight patients, improved in five patients, and had deteriorated in four patients. CONCLUSIONS: Enterocele is corrected by using the Ripstein rectopexy. Persisting defecation difficulties after the Ripstein procedure are unlikely to be secondary to enterocele. The Ripstein procedure can be an alternative in the treatment of enterocele, as a majority of these patients also have rectal prolapse or rectal intussusception.     

Treatment of rectal prolapse in the elderly by perineal rectosigmoidectomy

The results and complications of perineal rectosigmoidectomy for complete rectal prolapse in 114 patients have been reviewed. Most patients were elderly and high risk by virtue of other concurrent medical conditions. Fourteen patients (12 percent) developed significant postoperative complications. Hospital stay was short (median, four days). Ten patients were lost to follow-up. The remaining 104 patients were followed for 3 to 90 months. Eleven patients (10 percent) developed recurrent fullthickness rectal prolapse; six of them underwent repeat perineal rectosigmoidectomy. Sixty-seven patients had fecal incontinence prior to surgery. Eleven patients underwent concomitant levatoroplasty; 10 of them either improved or regained full continence of feces postoperatively. Twenty-six of the 56 patients who underwent perineal rectosigmoidectomy alone improved or regained full continence. Rectal prolapse can be successfully treated by perineal rectosigmoidectomy in elderly, highrisk patients with minimal morbidity. Levatoroplasty dramatically improves fecal incontinence occurring in association with rectal prolapse.Read at the meeting of The American Society of Colon and Rectal Surgeons, Boston, Massachusetts, May 12 to 17, 1991.     

Clinical conundrum of solitary rectal ulcer

A retrospective study of 80 patients with biopsy-proven solitary rectal ulcer (SRU) was conducted to review its clinical spectrum. The median follow-up was 25 months. The female-to-male ratio was 1.41.0, and the mean age was 48.7 years (range, 14–76 years). Principal symptoms were bowel disturbances (74 percent) and rectal bleeding (56 percent). Twenty-one patients (26 percent) were asymptomatic and required no treatment. A previous wrong diagnosis was made in 25 percent. Rectal prolapse was identified in 28 percent (full-thickness, 15 percent; mucosal, 13 percent). The macroscopic appearance of the lesion seen in SRU varied widely and included polypoid lesions in 44 percent (the predominant finding in the asymptomatic group), ulcerated lesions in 29 percent (always symptomatic), and edematous, nonulcerated, hyperemic mucosa in 27 percent. Anorectal manometry provided little helpful information in the patients in whom it was performed. Management by bulk laxatives and bowel retraining led to symptomatic improvement in 19 percent of cases. In 29 percent of cases, symptoms persisted despite endoscopic healing of the lesion. Intractability of symptoms led to surgery in only 27 (34 percent) patients. Depending on the presence or absence of rectal prolapse, rectopexy or a conservative local procedure (such as local excision), respectively, appeared to be the optimal surgical treatment. The polypoid variety tended to respond to therapy more favorably than non-polypoid varieties. Thus, the macroscopic appearance of SRU has a significant bearing on the clinical course, and most cases do not require surgery.Read at the meeting of The American Society of Colon and Rectal Surgeons, Boston, Massachusetts, May 12 to 17, 1991.     

Recovery of anal sphincter function following transabdominal repair of rectal prolapse: Cause of improved continence?

Twenty-eight patients with complete rectal prolapse underwent anorectal manometry before and 6 months and 1–2 years after abdominal rectopexy and sigmoid resection in a study of the mechanisms responsible for postoperatively improved anal continence. Preoperatively, 22 patients reported defective anal control. Seven patients (all with minor incontinence) regained normal control and eight other patients achieved improved continence after surgery. Anal resting, squeeze, and voluntary contraction pressures were significantly lower for defective than for normal control, with a significant rise in these pressures at 6 months after the operation, except for those incontinent patients in whom continence was not improved. No further pressure rise was seen later. Improvement of continence was not accompanied by changes in rectal sensation or reflexive functions of the internal anal sphincter. These results suggest that recovery of the resting and voluntary contraction functions of the sphincter muscles was the cause of continence improvement observed after surgery. Anal manometry was unable to predict outcome of function. Therefore, supplementary procedures for restoration of continence are not advisable, although patients with only minor incontinence are likely to regain full continence after rectopexy alone.     

Incarcerated rectal prolapse—Rupture and ileal evisceration after failed reduction

We report a case of incarcerated rectal prolapse that could not be reduced after using the previously described application of ordinary table sugar. Gentle pressure caused the prolapsed rectum to perforate, and the small bowel herniated through the tear. This is only the second case reported in the literature of an ileal herniation through a perforated rectum after an attempted reduction of an incarcerated prolapse. It is the only reported case occurring after sugar application and the 42nd case of ileal herniation through the rectum from all causes.     

Defecographic findings in patients with anal incontinence and constipation and their relation to rectal emptying

PURPOSE: The aim of this study was to examine defecographic findings in patients with anal incontinence and constipation and to compare these findings with rectal emptying. METHODS: One hundred seventy-five preoperative defecographies documented on videotape in patients with either anal incontinence or constipation were retrospectively reviewed. The examinations were evaluated with respect to anatomic abnormalities of the rectum or anal canal. The results were compared with a semiquantitative assessment of rectal emptying as it appeared on the video sequence after one minute of strain. RESULTS: Anatomic abnormalities were found equally in incontinent and constipated patients, except for failure to open the anal canal, which was found only in constipated patients. Rectal intussusception was the most frequent finding. Abnormal defecograms were found in both sexes. Enteroceles, sigmoidoceles, and large rectoceles were found only in women. The presence of intussusception, lacking relaxation of the puborectalis muscle, and rectocele did not correlate with poor rectal emptying. Poor rectal emptying was also found in 19 of 58 patients with normal defecograms. CONCLUSIONS: Anatomic abnormalities of the rectum may be demonstrated independently of the clinical symptoms and are not always correlated to impaired rectal emptying. Since they may also be found in healthy controls, surgical correction of these abnormalities should be considered only with great caution.     

Does surgical repair of a rectocele improve rectal emptying?

PURPOSE: This study was undertaken to assess results of surgical repair of rectocele and to identify possible determinants of outcome from patient's history and preoperative defecography. Another aim was to evaluate how surgery affects rectal evacuation. METHOD: Thirty-four women with constipation and rectal emptying difficulties underwent surgery with a transanal technique. A preoperative defecography was performed in each patient. They were followed up after a median of 10 (range, 2–60) months with a questionnaire (n=34) and a defecography (n=31). Computer-based image analysis of defecographies was used to evaluate rectal evacuation. RESULTS: In 27 patients (79 percent), the result of surgery was good with subjectively improved emptying. The need for vaginal or perineal digitation preoperatively was related to a good result (P <0.05), whereas a previous hysterectomy (P <0.01) and a large rectal area on defecography (P <0.01) related to a poor result. Preoperative use of enemas, motor stimulants, or several types of laxatives also related to a poor outcome (P <0.05). Surgical treatment resulted in reduction of the rectocele (P <0.001), an elevated position of the anorectal junction (P <0.05), and improved rectal evacuation on defecographies (P <0.001). CONCLUSIONS: Surgical repair reduces the size of the rectocele and improves rectal emptying. These changes are accompanied by a symptomatic improvement in the majority of patients. Preoperative patient data and defecography may help in selecting patients for surgery.
