Purpose:
Functional anorectal conditions are common, and management is challenging. Conservative management may not always be successful and some of these patients may opt for stoma formation. Rectal stump symptomatology after surgery is poorly understood with limited existing literature in this field. The aim of this study is to investigate the prevalence of rectal stump symptomatology in patients undergoing stoma creation for benign functional anorectal conditions.
Method:
A retrospective chart review for patients undergoing stoma formation for functional anorectal conditions at two metropolitan hospitals was conducted. Patient demographics and incidence of rectal stump symptoms were documented and analysed.
Results:
Thirty-nine patients underwent stoma formation over a 7-year period. The average age was 55 years and 90% of patients were female. End colostomy was performed in 23 (59%) patients, one patient underwent a loop colostomy, and the remaining patients (15) underwent loop ileostomy. Post-operative symptoms associated with the rectal stump were common and included problematic rectal mucus discharge (51%), pelvic pain (21%), rectal impaction (5%), tenesmus (3%) and rectal prolapse (3%). Overall, 65% of patients underwent at least one intervention for persistent rectal mucus discharge, including enemas (38%), irrigation (38%) or completion proctectomy (23%). In total, 92% of patients were noted to have satisfactory control of symptoms with a median follow-up time of 3 years.
Conclusions:
Rectal stump symptomatology is common in patients undergoing a defunctioning stoma for benign functional anorectal conditions. Many of these patients require ongoing management to control their symptoms, including in some cases a completion proctectomy. This study forms the basis for further research on rectal stump symptomatology in this complex cohort of patients.

01:24Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
