BMC Surg. 2022 Aug 1;22(1):298. doi: 10.1186/s12893-022-01744-3.

Abstract

Background: Stapled haemorrhoidopexy (SH) has resulted in a unique collection of procedural complications with postoperative mucocele a particularly rare example. This study is designed to comprehensively describe the characteristics of rectal mucocele and discuss its pathogenesis following SH surgery.

Methods: A database of patients presenting with a rectal mucocele following an SH procedure was established and studied retrospectively.

Results: Seven patients (5 males; median age 32 years, range 20-75 years) were identified. All patients complained of variable anal discomfort with 5/7 presenting with inconstant anal pain, 2 with de novo evacuatory difficulty. These cases appeared at a median time of 6 months (range 2-84 months) after SH surgery.

Conclusion: Rectal Mucocele develops when mucosal fragments become embedded and isolated under the mucosa. It is a preventable complication of SH surgery by ensuring correct purse string placement prior to stapled haemorrhoid excision.

Keywords: Complication; Mucocele; Stapled haemorrhoidopexy.
