Double-Layered Hand-Sewn versus Stapled Intestinal Anastomosis in Patients Who Underwent Ileal Urinary Diversion in Radical Cystectomy: A Comparative and Cost Effective Study

Introduction: Intestinal anastomosis can be performed by hand suturing (single layer or double layer) or by a mechanical suturing machine. The aim of the study was to compare complications, operative time, and costs of the intestinal anastomosis techniques. Methods: A retrospective comparative study was conducted including patients who underwent radical cystectomy and uretero-ileo-cutaneostomy or vescica ileale Padovana orthotopic neobladder. Double-layered hand-sewn intestinal anastomosis (HS-IA) were performed using Vicryl stitches. Mechanical-stapled intestinal anastomosis (MS-IA) were performed with a mechanical stapler. Results: Data of 195 patients who underwent were collected. 100 (51.3%) patients underwent HS-IA and 95 (48.7%) patients underwent MS-IA. Considering the complications classified according to Clavien-Dindo, a statistical difference with higher incidence for grade one in the HS-IA both in the ileal conduit group and in the neobladder one than the MS-IA (15.8% and 8.7%, respectively, in HS-IA vs. 1.7% and none in MS-IA). There is not a significant difference in time to flatus and time to defecation. Difference is recorded in the ileal conduit groups for the length of stay (10 days, range 9-12 with HS-IA vs. 13 days range 12-16 days with MS-IA (p < 0.001). The cost of the suture thread used for a single operation was 0.40 euros, whereas the overall cost of a disposable mechanical stapler and one refill was 350.00 euro. Conclusion: Both HS-IA and MS-IA are safe and effective for patients. The cost for the stapling device is 350 euro, in contrast, the cost for Vicryl sutures is negligible.
