Outcomes for patients developing anastomotic leak after ileal pouch-anal anastomosis: does a handsewn vs. stapled anastomosis matter?
OBJECTIVE
Outcomes for patients developing a leak after ileal pouch-anal anastomosis have not been well investigated. This study explored whether the use of a stapled or handsewn anastomosis was associated with different outcomes when an anastomotic leak developed.


METHODS
Patients were identified from a prospectively maintained pouch database. Functional outcomes regarding bowel movements, urgency, continence, and seepage were evaluated. Quality of life was assessed by the Cleveland Global Quality of Life Score.


RESULTS
One hundred and seventy-five patients with anastomotic leak (141 stapled and 34 handsewn anastomosis) were identified. The two groups were similar in gender and diagnosis. Patients with handsewn anastomosis were younger (P = 0.04), had less perioperative steroid use (P = 0.05), more proximal diversion (P = 0.02), and S-pouch creation (P = 0.003). More handsewn cases had intraoperative transfusion (P = 0.04) and postoperative hemorrhage within the pelvis (P = 0.003). Long-term pouch failure was 35.3 percent in the handsewn group and 12 percent in the stapled group (P = 0.002), which was confirmed by Kaplan-Meier analysis (Log-rank P = 0.007). On multivariate analysis, leak after handsewn anastomosis was independently associated with pouch failure. Leak after stapled anastomosis carried a lower incontinence rate at 5 years (P = 0.03), while handsewn had higher nocturnal seepage rate at 3, 5, and 10 years, and most recent follow-up. Cleveland Global Quality of Life Score was comparable between the groups during follow-up.


CONCLUSIONS
Outcomes including functional results and pouch failure rates for patients developing a leak after stapled anastomosis at ileal pouch-anal anastomosis were significantly better than outcomes for patients who develop a leak after handsewn anastomosis.
