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.
A database of patients presenting with a rectal mucocele following an SH procedure was established and studied retrospectively.
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.
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.
吻合器痔上黏膜环切术（SH）导致了一系列独特的手术并发症，其中术后黏液囊肿是一种特别罕见的例子。本研究旨在全面描述直肠黏液囊肿的特征，并讨论其在 SH 手术后的发病机制。
建立了数据库，对接受 SH 手术后出现直肠黏液囊肿的患者进行回顾性研究。
共发现 7 名患者（5 名男性；中位年龄 32 岁，范围 20-75 岁）。所有患者均有不同程度的肛门不适，5 例诉间歇性肛门疼痛，2 例诉新发排便困难。这些病例在 SH 手术后的中位时间为 6 个月（范围 2-84 个月）。
直肠黏液囊肿是在黏膜下的黏膜碎片被嵌入和隔离时发展起来的。通过确保在吻合器痔上黏膜切除术前正确放置荷包缝线，可以预防 SH 手术的这种并发症。
