Stapled restorative proctocolectomy in children with refractory ulcerative colitis.

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Inflammatory Bowel Disease

Background:

• Ulcerative colitis (UC) is a chronic inflammatory bowel disease affecting the colon.
• Refractory UC in children often necessitates surgical intervention, including colectomy and ileoanal anastomosis.
• Restorative proctocolectomy with stapled anastomosis is a surgical option for managing pediatric UC.

Purpose of the Study:

• To evaluate the outcomes of stapled restorative proctocolectomy in children with refractory ulcerative pancolitis.
• To assess the incidence of complications, anastomotic function, and long-term results.
• To investigate the prevalence and impact of cuffitis and ileal inflammation.

Main Methods:

• Retrospective review of 16 children with refractory ulcerative pancolitis who underwent stapled straight ileoanal anastomosis.
• Clinical examinations and endoscopic assessments with biopsies of the terminal ileum and columnar cuff during follow-up.
• Median follow-up of 5.3 years after bowel restoration.

Main Results:

• Low major complication rate (12.5%), with no cases of dysplasia or cancer.
• All anastomoses were functional; however, 94% of children had persistent cuff inflammation (cuffitis), mostly asymptomatic.
• Continence was achieved in 87.5% for daytime and 62.5% for nighttime; severe cuffitis correlated with nighttime incontinence.

Conclusions:

• Stapled ileoanal anastomosis in pediatric ulcerative pancolitis is associated with low morbidity.
• Persistent cuffitis is common but generally asymptomatic, though it can be linked to nighttime incontinence.
• This surgical approach offers functional restoration with manageable long-term inflammatory changes.
