Colectomy for constipation: physiologic investigation is the key to success

Area of Science:

• Gastroenterology and Surgical Procedures

Background:

• Colonic inertia (CI) is a severe form of chronic constipation.
• Conservative treatments often fail for patients with diffuse colonic inertia.
• Total abdominal colectomy (TAC) with ileorectal anastomosis is a surgical option for refractory CI.

Purpose of the Study:

• To prospectively assess the outcomes of TAC with ileorectal anastomosis for treating colonic inertia.
• To evaluate the efficacy and patient satisfaction following this surgical intervention.

Main Methods:

• Prospective evaluation of 163 patients with chronic constipation.
• Physiological testing including pancolonic transit times, anorectal manometry, cinedefecography (CD), and electromyography (EMG) to diagnose CI.
• TAC performed on 16 selected patients with confirmed CI.

Main Results:

• No postoperative mortality or major morbidity observed.
• Three patients experienced partial small bowel obstruction, successfully managed conservatively.
• At mean 15-month follow-up, patients reported a mean of 3.5 spontaneous bowel evacuations daily.
• 94% of patients reported "excellent" or "good" satisfaction with the surgical outcome.

Conclusions:

• Total abdominal colectomy (TAC) with ileorectal anastomosis is a safe and effective treatment for carefully selected patients with colonic inertia.
• Thorough preoperative physiological evaluation is crucial for identifying patients who will benefit from TAC.
• The procedure significantly improves bowel function and patient quality of life in this specific patient group.
