J-Pouch Surgery in Los Angeles
Expert J-Pouch surgery from Dr. Yosef Nasseri — restoring near-normal bowel function after colon removal, most often without a permanent ostomy.
Restoring Function After Colon Removal
J-Pouch surgery is a restorative procedure for patients who need their colon and rectum removed, most often due to ulcerative colitis or certain hereditary conditions. Instead of a permanent ostomy, the surgeon builds an internal pouch from the small intestine so that stool passes naturally.
For the right patient, J-Pouch surgery is life-changing: it removes the diseased tissue, cures the underlying colitis, and preserves quality of life. Dr. Nasseri performs these technically demanding operations robotically for a gentler recovery.

How J-Pouch Surgery Works
J-Pouch surgery is usually performed in planned stages for the safest result and the best long-term function.
Colon Removal
The diseased colon is removed, and a temporary ileostomy allows the body to heal.
Pouch Construction
The end of the small intestine is folded into a J shape and connected just above the anus.
Ostomy Closure
The temporary ileostomy is closed, restoring natural bowel continuity.
Who Is a Candidate
J-Pouch surgery is most often recommended for patients with ulcerative colitis whose disease is not controlled by medication, or for those with familial adenomatous polyposis. It is also an option after certain complications or precancerous changes.
Because pouch construction is technically demanding, outcomes are closely tied to surgeon experience. Dr. Nasseri evaluates each patient carefully, discusses expectations honestly, and also performs redo procedures for patients whose original pouch is not functioning well.
Why Choose a J-Pouch
For suitable patients, this reconstruction offers meaningful, lasting advantages over a permanent ostomy.
No Permanent Ostomy
Most patients avoid a permanent bag and pass stool naturally after recovery.
Cures the Colitis
Removing the colon and rectum eliminates ulcerative colitis and its cancer risk.
Robotic Technique
Minimally invasive construction means less pain, smaller scars, and a faster recovery.
Excellent Quality of Life
After the pouch adapts, most patients enjoy a broad diet and an active, unrestricted life.
Redo Expertise
Dr. Nasseri also repairs poorly functioning pouches built elsewhere.

J-Pouch Surgery FAQs
Will I need a permanent ostomy?
Usually not. The purpose of J-Pouch surgery is to restore natural bowel function and avoid a permanent ostomy. A temporary ileostomy is used during healing and later closed.
What is life like after a J-pouch?
After the pouch adapts over several months, most patients eat a broad diet, travel freely, and enjoy an active life, free from the flares and urgency of their original disease.
When should I consider J-Pouch surgery?
The right timing depends on your diagnosis and goals. Dr. Nasseri reviews your situation and recommends J-Pouch surgery only when it is the best option for you. Call (424) 655-3312 to be seen this week in Los Angeles.
