Overview
Removing the whole colon when one segment is not enough.
Total colectomy is the operation that removes the entire colon — from the cecum to the upper rectum — in a single procedure. The two most common reasons we recommend it are medically refractory ulcerative colitis and hereditary cancer syndromes (familial adenomatous polyposis and Lynch syndrome) where the whole colon is at risk. We also use it for synchronous colon cancers occupying multiple segments, for selected cases of colonic inertia, and emergently for toxic megacolon. The reconstruction depends on the indication: the small bowel can be reconnected directly to the rectum (ileorectal anastomosis) or shaped into a pouch and connected to the anus (J-pouch, also called IPAA), often with a temporary protective ileostomy.
We perform the great majority of elective total colectomies minimally invasively — robotically or laparoscopically — through five to six small abdominal incisions. The specimen is removed through one slightly larger incision. Total colectomy is a longer operation than a single segmental resection, but recovery from a minimally invasive approach is dramatically smoother than from a long midline open incision. For inflammatory bowel disease and hereditary cancer syndromes, the planning conversation in the office before surgery often takes more time than the surgery itself — picking the right reconstruction is a decision you and your surgeon should make together.
Who is a candidate?
Candidates include patients with ulcerative colitis that has not responded to advanced medical therapy or that has produced dysplasia or cancer; patients with familial adenomatous polyposis (FAP) whose polyp burden is no longer safely managed by colonoscopy; Lynch syndrome patients who develop a colon cancer (where prophylactic removal of the rest of the colon is often the right answer); patients with synchronous cancers in multiple segments; and select patients with severe colonic inertia confirmed by transit and physiology studies. The choice between an ileorectal anastomosis and a J-pouch is driven by the diagnosis, the condition of the rectum, sphincter function, and patient preference.
How we perform it
Under general anesthesia, five to six small ports are placed in the abdomen. We mobilize the colon along all four flexures, divide the feeding vessels (ileocolic, right colic, middle colic, inferior mesenteric) at their origins for cancer cases or closer to the bowel wall for benign disease, and divide the terminal ileum and upper rectum. Reconstruction is tailored: an ileorectal anastomosis for many FAP and inertia patients, or a J-pouch with temporary protective loop ileostomy for ulcerative colitis and selected polyposis patients. The specimen is removed through a small protected incision. Operations typically take 4–6 hours.
Recovery
Most patients stay 4–7 nights. You will walk the evening of surgery and start clear liquids over the next day or two as bowel function returns. Expect 4–6 stools per day after ileorectal anastomosis and 5–8 per day after J-pouch initially, with the pattern improving over the first 6–12 months. Desk work resumes at 4–6 weeks; lifting and full activity at 6–8 weeks. When a temporary ileostomy is present, we send you home with stoma teaching and bring you back for reversal once the new connection has healed — usually 8–12 weeks later.
Why Florida Surgical
Dr. Shaw is fellowship-trained in surgical oncology and performs robotic colectomy at high volume across our South Florida hospitals. Total colectomy is one of the operations where the planning conversation matters as much as the technique. We work closely with gastroenterology, genetics, and medical oncology partners so the right reconstruction is chosen for the right diagnosis, and we follow you long-term in our Coral Springs office for surveillance of any remaining bowel.
Frequently asked questions
Will I need a permanent stoma?
Most patients do not. Depending on the indication, the small bowel is either reconnected directly to the rectum or used to form a J-pouch and connected to the anus. A temporary loop ileostomy is often used to protect the connection while it heals and is reversed 8–12 weeks later. A permanent end ileostomy is only required in specific situations — for example, when sphincter function or rectal disease makes a continent reconstruction unsafe.
How many bowel movements will I have?
After ileorectal anastomosis, expect 4–6 stools per day, often somewhat looser than baseline. After J-pouch, expect 5–8 stools per day at first. Most patients adapt over 6–12 months and reach a manageable, predictable pattern. Anti-motility medications and a low-residue diet help in the early weeks.
How long is recovery?
Hospital stay is typically 4–7 days. Most patients return to desk work in 4–6 weeks and full activity at 6–8 weeks. When a temporary ileostomy is planned, the reversal happens 8–12 weeks later and the recovery from the reversal is much shorter — usually 2–3 weeks.
Is robotic better than open?
For appropriate patients, robotic and laparoscopic total colectomy give less pain, smaller scars, and faster recovery than open, with equivalent oncologic and inflammatory bowel disease outcomes. The robot's wrist articulation is particularly valuable when working at all four flexures in a single operation.
What is a J-pouch?
A J-pouch (ileal pouch–anal anastomosis, or IPAA) is a reservoir made from the small bowel and connected to the anus, giving stool the time to be stored before evacuation. It is the standard reconstruction after total proctocolectomy for ulcerative colitis and many polyposis patients, and allows normal anal continence over time. We discuss the trade-offs with each patient in detail before surgery.
