New kid on the block: perineal stapled prolapse resection (PSP) is it worthwhile in the long-term?

Outcomes for men undergoing rectal prolapse surgery - a systematic review

AIM

Rectal prolapse is considered rare in men but the prevalence can be high in certain populations. It is unclear which surgical approach offers lower recurrence rates and better functional outcomes in men. The aim of this work was to determine the recurrence rates, complications and functional outcomes after prolapse surgery in men.

METHOD

The MEDLINE, EMBASE and Scopus databases were systematically searched to identify studies on outcomes following surgical management of full-thickness rectal prolapse in men (over 18 years of age) published between 1951 and September 2022. Outcomes of interest included recurrence rate after surgery, bowel function, urinary function, sexual function and postoperative complications.

RESULTS

Twenty-eight studies involving 1751 men were included. Two papers focused exclusively on men. Twelve studies employed a mixture of abdominal approaches, ten employed perineal approaches and six compared both. The recurrence rate varied across studies, ranging from 0% to 34%. Sexual and urinary function were poorly reported, but the incidence of dysfunction appears low.

CONCLUSION

The outcomes of rectal prolapse surgery in men are poorly studied with small sample sizes and variable outcomes reported. There is insufficient evidence to recommend a specific repair approach based on the recurrence rate and functional outcomes. Further studies are required to identify the optimal surgical approach for rectal prolapse in men.

Perineal stapled prolapse resection for external rectal prolapse: a systematic review and meta-analysis

AIM

Rectal prolapse is an uncommon but debilitating pelvic floor disorder that significantly decreases the quality of life of affected patients. Perineal stapled prolapse resection is a relatively new perineal approach that offers an promising alternative technique in the surgical management of rectal prolapse. It appears to be a simple, reproducible and efficient method. However, long-term outcomes are limited. The aims of this review are to assess the safety and effectiveness of perineal stapled prolapse resection in the management of rectal prolapse.

METHOD

A systematic review of all articles describing this approach was searched using MEDLINE, Embase, PubMed, Cochrane, Scopus, Web of Science and China National Knowledge Infrastructure. Included in this review were all randomized and nonrandomized prospective and retrospective studies reporting patients (aged 16 years and older) with complete rectal prolapse who underwent perineal stapled prolapse resection for the surgical treatment of the rectal prolapse.

RESULTS

A total of 408 patients across 20 articles were included. There were 58 cases of recurrence out of 368 patients over a median length of follow-up of 18 months (interquartile range 12-34 months). The total weighted overall recurrence was 12%. There were 51 cases of postoperative complications in 350 cases, bleeding being the most common complication.

CONCLUSION

The recurrence rate is comparable to those of the well-established Altemeier and Delorme procedures. However, given the heterogeneity of studies and variations in lengths of follow-up, further randomized prospective studies are needed to adequately compare this technique against other procedures for complete rectal prolapse.

Perineal resectional procedures for the treatment of complete rectal prolapse: A systematic review of the literature

BACKGROUND AND AIM

Several procedures for the treatment of complete rectal prolapse (CRP) exist. These procedures are performed via the abdominal or perineal approach. Perineal procedures for rectal prolapse involve either resection or suspension and fixation of the rectum. The present review aimed to assess the outcomes of the perineal resectional procedures including Altemeier procedure (AP), Delorme procedure (DP), and perineal stapled prolapse resection (PSR) in the treatment of CRP.

PATIENTS AND METHODS

A systematic search of the current literature for the outcomes of perineal resectional procedures for CRP was conducted. Databases queried included PubMed/MEDLINE, SCOPUS, and Cochrane library. The main outcomes of the review were the rates of recurrence of CRP, improvement in bowel function, and complications.

RESULTS

Thirty-nine studies involving 2647 (2390 females) patients were included in the review. The mean age of patients was 69.1 years. Recurrence of CRP occurred in 16.6% of patients. The median incidences of recurrence were 11.4% for AP, 14.4% for DP, and 13.9% for PSR. Improvement in fecal incontinence occurred in 61.4% of patients after AP, 69% after DP, and 23.5% after PSR. Complications occurred in 13.2% of patients. The median complication rates after AP, DP and PSR were 11.1%, 8.7%, and 11.7%, respectively.

CONCLUSION

Perineal resectional procedures were followed by a relatively high incidence of recurrence, yet an acceptably low complication rate. Definitive conclusions on the superiority of any procedure cannot be reached due to the significant heterogeneity of the studies.

[Transtar™ operation for rectocele and obstructed defecation syndrome]

The Contour® Transtar™ operation represents a further methodological development of conventional transanal stapled rectal resection (STARR) for the treatment of obstructed defecation syndrome (ODS) and/or full thickness rectal prolapse. In contrast to the conventional STARR technique a specially designed single curved stapler is used with which the rectal wall is incised in a circular fashion and anastomosed. This results in a monoblock resection with almost unlimited extent of resection. In multicenter studies the procedure has generally been shown to be effective for treatment of ODS with intussusception and rectocele. In comparison to conventional STARR the resected tissue samples are larger and the functional effectiveness is comparable. Furthermore, data from prospective randomized trials revealed higher effectiveness in long-term follow-up. With reference to full thickness rectal prolapse, feasibility studies have been performed which showed low morbidity but long-term follow-up studies suggest a high recurrence rate of >40 %.
