Combined aluminum potassium sulfate and tannic acid sclerosing therapy and anal encirclement using an elastic artificial ligament for rectal prolapse.

BACKGROUND

Aluminum potassium sulfate and tannic acid is a sclerosant used for sclerosing therapy in the treatment of hemorrhoids, and a Leeds-Keio artificial ligament is a new anal-encircling material for the management of rectal prolapse.

OBJECTIVE

The aim of this study was to evaluate clinical data and recurrence rates in patients with rectal prolapse undergoing combined aluminum potassium sulfate and tannic acid injection and anal encirclement using the Leeds-Keio artificial ligament.

METHODS

This was a retrospective review of patients who underwent this procedure.

METHODS

This study was conducted at a community-based hospital within a specialized colorectal unit.

METHODS

A total of 23 patients (20 women; median age, 83 years) with full-thickness rectal prolapse underwent treatment between 2005 and 2010.

METHODS

The main outcome measures were morbidity and recurrence rate.

RESULTS

The median duration of surgery was 36 minutes. Mean total injection dose of aluminum potassium sulfate and tannic acid was 30 mL. There were no postoperative deaths. Wound infection occurred in 2 patients (9%), and new or worsening symptoms of constipation after surgery occurred in 6 patients (26%). There were 3 recurrences at a median follow-up of 36 months (range, 7-86 months). Recurrence rate at 5 years was 14% (95% CI, 5%-35%).

CONCLUSIONS

The limitations of this study include its retrospective nature, the potential for selection bias, and lack of a control group.

CONCLUSIONS

This procedure is quick and easy to perform, with no formidable morbidity, and the recurrence rate is reasonably low. Therefore, it seems to be a reasonable alternative for rectal prolapse in frail, elderly, and high-risk patients.
