Iatrogenic rectal cyst formation
Tóm tắt
Transanal stapling, or circumferential mucosectomy, is one of several well-established techniques for the treatment of haemorrhoids and rectal prolapse. We report a rare complication following the procedure and discuss related issues emerging from our review of the current literature. We report the case of a 50-year-old woman who presented with a pelvic mass. She had undergone stapled haemorrhoidectomy seven years previously. Physical examination and imaging established the presence of a rectal cyst thought to be the result of the stapling procedure. Following unroofing of the cyst, the symptoms resolved completely. We also present a literature review following a search of the Pubmed database for relevant reports up to December 2015. All case reports and case series were included, without any restriction in terms of language or publication status. Twenty-five similar cases were published up to December 2015. A review of the papers showed a universal approach for the diagnosis and treatment of this rare complication Rectal cyst formation is an infrequent complication of stapled haemorrhoidectomy. Nonetheless, the emergence of symptoms follows a recognizable pattern. In the first three months following surgery, pain is the dominant feature while in patients developing symptoms later, obstructive constipation is the commonest manifestation. Surgeons adopting the procedure are aware of this complication but may neglect making full use of magnetic resonance imaging (MRI) and other advanced techniques to facilitate diagnosis. Unroofing of the cyst using the transanal approach offers a worthwhile treatment option.
