Long-term outcome after colectomy in severe idiopathic constipation

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Surgical Outcomes

Background:

• Severe idiopathic constipation significantly impacts quality of life.
• Surgical interventions are considered for refractory cases.
• Subtotal colectomy with ileorectal anastomosis is a potential treatment option.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of subtotal colectomy with ileorectal anastomosis.
• To assess patient satisfaction and functional outcomes after the procedure.
• To identify potential complications and secondary morbidity.

Main Methods:

• A cohort of 40 patients with severe idiopathic constipation underwent subtotal colectomy and ileorectal anastomosis between 1981 and 1993.
• Patients were selected after thorough gastrointestinal investigation, confirming slow transit and infrequent bowel movements.
• Long-term follow-up assessed defaecation frequency, patient satisfaction, and complications.

Main Results:

• Mean follow-up was 11 years. Defaecation frequency increased significantly post-surgery.
• Twenty-nine out of 40 patients (72.5%) reported satisfaction with the procedure.
• Seventeen patients experienced small bowel obstruction, requiring surgical intervention in 10 cases. Seven patients required further procedures.

Conclusions:

• Subtotal colectomy with ileorectal anastomosis can improve bowel movement frequency in severe idiopathic constipation.
• While generally effective, the procedure is deemed successful by only a majority of patients.
• Considerable secondary morbidity, particularly small bowel obstruction, necessitates careful patient selection and management.
