How I do it: the stapled ileal J pouch at restorative proctocolectomy

Area of Science:

• Surgical innovation in gastrointestinal surgery.
• Inflammatory Bowel Disease (IBD) management.

Background:

• Ileal pouch-anal anastomosis (IPAA) is a key surgery for ulcerative colitis, indeterminate colitis, and familial adenomatous polyposis.
• Complications such as pelvic sepsis, fistulae, and anastomotic dehiscence can lead to pouch failure.
• A modified stapling technique using the GIA™ 100 device was developed to improve J-pouch formation.

Purpose of the Study:

• To report the institutional experience with an adapted GIA stapling technique for ileal J-pouch formation.
• To evaluate the impact of this modification on postoperative morbidity and pouch outcomes.

Main Methods:

• Retrospective review of 41 patients undergoing elective IPAA with the adapted stapling technique over 5 years.
• Data collected from an inflammatory bowel disease database, theater records, and patient charts.

Main Results:

• No mortality was observed in the series of 41 patients.
• Postoperative morbidity occurred in 11 patients (pelvic sepsis, fistulae, stricture, leak).
• No complications were related to blind efferent limbs or transverse staple line disruption.

Conclusions:

• Modifying the GIA stapling device by removing the protector allows completion of the staple line to the pouch tip.
• This technique may reduce redundant J-pouch limb length, potentially decreasing torsion, volvulus, and sepsis.
• The adaptation appears to minimize specific complications associated with blind efferent limbs and transverse staple line integrity.
