Complications are Increased with the Need for an Abdominal-Assisted Kraske Procedure

Abstract

The Kraske procedure offers a sphincter-saving alternative for surgical correction of rectal disease. This study was performed to investigate the complication rate with the traditional (transsacral) Kraske procedure versus an abdominal-assisted Kraske approach (laparoscopic or open). We conducted a retrospective review of all patients undergoing the Kraske procedure at Harper University Hospital over a 10-year period. A total of 54 patients were identified. Indications for surgery included rectal carcinoma (43), large villous adenomas (6), and other (5). Average post-operative follow-up was 40 +/- 25 months (mean +/- SD). Complications included rectocutaneous fistulae (9), perineal infections (13), and incontinence (8). In patients requiring an abdominal-assisted approach for colorectal mobilization, the fistula rate was significantly higher (33% vs 3%; P = 0.007), as were the rates of perineal infections (33% vs 17%) and of initial incontinence (25% vs 7%). The laparoscopic-assisted approach significantly reduced the operating time (272 +/- 72 minutes) compared to the open-assisted approach (498 +/- 138 minutes) (P < 0.001). The traditional Kraske procedure can be utilized in a safe, effective manner for treatment of rectal disease. Knowledge of the increased rate of complications with the abdominal-assisted Kraske approach can guide the patient and physician considering sphincter salvage.
