Trilumenal hybrid-NOS proctocolectomy

The authors hypothesized that by combining transumbilical, transvaginal, and transrectal accesses, complex bowel operations, including proctocolectomy with restorative J pouch [corrected] reconstruction, might be possible.

Out of a series of 30 natural orifice surgery (NOS) operations performed at the authors' institution in the past 12 months, proctocolectomy with ileoanal pouch reconstruction was planned for 3 female patients (31 years, BMI = 30; 50 years, BMI = 31; 30 years, BMI = 21) with extensive disease of ulcerative colitis, and they were operated via a 3-lumenal NOS approach. The first 2 patients received a proctocolectomy with a J-pouch formation. A 3-stage procedure was planned for the third patient, and she received a total colectomy. The colonic specimen was retrieved through the anus obviating dilation of the vagina. The J-pouch was prepared through a horizontal 2-cm incision, which later served as the protective loop ileostomy site.

Trilumenal NOS proctocolectomy is feasible and safe providing a solution to overcome the lack of triangulation using a single-lumen approach.
