ABSTRACT

OBJECTIVES: This study analyzed the results of transanal rectopexy and showed the benefits of this surgical technique.
METHOD: Twelve patients were submitted to rectopexy between 1997 and 2011. The surgical technique used was transanal rectopexy, where the mesorectum was fixed to the sacrum with nonabsorbable suture. Three patients had been submitted to previous surgery, two by the Delorme technique and one by the Thiersch technique.
RESULTS: Postoperative hospital stay ranged from 1 to 4 days. One patient (8.3%) had intraoperative hematoma, which was treated with local compression and antibiotics. One patient (8.3%) had residual mucosal prolapse, which was resected. Prolapse recurrence was seen in one case (8.3%). Improved incontinence occurred in 75% of patients and one patient reported obstructed evacuation in the first month after surgery. No death occurred.
CONCLUSION: Transanal rectopexy is a simple, low cost technique, which has shown good efficacy in rectal prolapse control.

Keywords: rectum; rectal prolapse; colorectal surgery.


RESUMO

OBJETIVO: O presente estudo analisou os resultados da retopexia pela via transanal e expôs os benefícios desta técnica cirúrgica.
MÉTODO: Doze pacientes com prolapso foram operados no período de 1997 a 2011. A técnica cirúrgica usada foi a retopexia transanal, onde o mesorreto foi fixado ao sacro com fio inabsorvível. Três pacientes tinham cirurgia prévia, dois pela técnica de Delorme e um pela técnica de Thiersch.

INTRODUCTION

Rectal prolapse is the protrusion of all rectal walls through the anal canal. It affects women more often than men, at the ratio of 6:11. Several treatment methods have been proposed, either through abdominal or perineal approach. Few studies have been conducted to guide our practice, and good results have been achieved with both abdominal and perineal techniques2. The reduced number of patients with this pathology at each service of Coloproctology is certainly a limitation to studies comparing these surgical techniques.

Perineal rectopexy, introduced in 19103, uses gas in the retrorectal space for several days; with high recurrence, the technique has not become popular. Transperineal4, transsacral5 and postanal6 approaches have also been used, but without high acceptance. Transanal rectopexy has been used only in association with Altemeier7 e Delorme8 techniques, for reduced recurrence. No utilization of transanal rectopexy as an isolated technique has not been described.

The purpose of this study is to present the results of transanal rectopexy and the technical description of the procedure.

 

PATIENTS AND METHODS

Twelve patients, three males and nine females, aged 34 to 88, were submitted to rectopexy. Prolapse duration ranged from 1 to over 10 years. Three patients had been submitted to previous surgery for prolapse, two by the Delorme technique, with recurrence, and one, with external prolapse and mucosal ischemia, was submitted to urgent Thiersch surgery and subsequently to transanal rectopexy. Table 1 shows the clinical details of patients. The prolapse of patients submitted to rectopexy was 4- 10 cm long.

Surgical technique

All patients were in the lithotomy position during the surgery, and received regional or local anesthesia with sedation (one patient only). After prolapse reduction and rectal retactor placement, the rectum returns to its original position. The following retactors were used: circular anal retactor, vaginal speculum 4 and composite anoscope (130 x 40 mm). With all these instruments, it is possible to perform the surgery. The mucosa is rinsed with physiological saline solution, and, after that, an incision is made in the posterior rectal wall, starting 6 cm and ending 10 cm from the anal margin. As the mesorectum was exposed, it was fixed to the pre-sacral fascia with nonabsorbable suture, using 40 mm atraumatic needles. The needle should be long enough to enable the passage through the pre-sacral fascia and expose the needle tip to end stitching. After 3-4 stitches are made, the threads are tied and the rectal wall is tensioned to test its fixation. It is rinsed again and the rectal wall is closed with absorbable suture #00 or #000. All patients received antibiotic prophylaxis. Figures 1 and 2 show the rectal wall incision and the final aspect after rectopexy and rectal wall suture.

 

 

 

 

RESULTS

The immediate postoperative period was asymptomatic and the patients did not require opioid analgesics. Hospital stay ranged from 1 to 4 days. The only patient hospitalized for 4 days presented retrorectal hematoma after stitching, which was treated with local compression during the surgery and antibiotics for 7 days.

The patients were supervised for periods that varied from 6 months to 14 years. Three patients died within one to three years after the surgery, without signs of recurrence. Two patients have not been found anymore, but they were supervised up to one year after the surgery and did not present prolapse recurrence. One patient presented prolapse recurrence 2 months after the surgery (8.3%) and was again submitted to the same surgical technique, with good results. One patient presented residual anterior mucosal prolapse and was treated with local resection 6 moths after rectopexy.

The functional result showed partial or total incontinence improvement in 6 patients (75%), and 2 incontinent patients (25%) did not presented alteration to fecal loss. The levator-muscle surgery was recommended to these incontinent patients, but it was not performed, following the decision of patients and their relatives. Patients with incontinence before the surgery did not present any change in this clinical aspect after the transanal rectopexy. Constipation, present in 40% of patients before the surgery, had no change. One patient that had no constipation before rectopexy reported obstructed evacuation in the first preoperative month. She was treated with mini enemas and fiber and presented spontaneous improvement. No mortality was seen with the technique described in this study.

 

DISCUSSION

Abdominal procedures for prolapse treatment are related to lower recurrence1. The current abdominal surgery is based on rectopexy, as other procedures that do not include it have been discarded2. However, rectal dissection is associated with constipation and obstructed evacuation9-11, and the lateral ligament division increases such incidence12. The recurrence rate after rectopexy with or without associated sigmoidectomy is the same13,14.

High morbidity rates of abdominal procedures used in pathologies associated with older age encouraged the development of perineal techniques. The prolapse treatment via perineal procedure has become the preferred choice in elderly and debilitated patients. These surgeries are safe, the anesthetic risk is low and the recovery is fast15, but they have presented higher recurrence rates than abdominal surgery.

Published studies present wide discrepancy in terms of recurrence after perineal rectosigmoidectomy, ranging from 0 to 60%1. Functional results were also discouraging at first13, but they improved with combined levator-muscle repair16-18. The combination of rectopexy with the Altemeier technique described by Prasad et al.7 shows the benefit of fixing the rectum to the sacrum, leading to lower recurrence. Despite the excellent functional results of this study, one death was reported among 25 patients. Anastomotic fistula occurred in another study series, in 16.6% of the patients19; then, resection and anastomosis are associated with high morbimortality20.

Another study associated transanal rectopexy with Delorme surgery8, obtaining reduction in the recurrence rate, from 20 to 5%. Rectopexy was performed only with the placement of absorbable mesh in the retrorectal space. Douglas pouch suture was also associated with this technique. This method also presented high morbidity rate, although not statistically significant.

The technical innovation presented in this study shows the benefits of rectopexy, a consolidated technique of lower recurrence rates, and the transanal approach advantages, which make the procedure fast and technically easy to be performed. The possibility of abscess occurrence seems to be discarded, as perirectal tissues are not dissected and synthetic meshes are not used. Hematomas may occur with the needle passing through the sacral fascia, but, in this study, the hematoma did not lead to complications and was treated with local compression during the surgery. Levator-muscle repair was performed in the patient with persistent incontinence after the prolapse correction.

 

CONCLUSION

Transanal rectopexy uses the sphincter hypotonia, an anatomical aspect in patients with rectal prolapse, which makes it a relatively easy procedure. The recurrence rate was low, with minimum morbidity. Even treating patients at older ages, no mortality was seen with the technique described in this study. This is also a low cost technique. However, the comparison of this technique to other methods requires additional prospective studies.
