Rectal Hem-o-Lok clip migration after robot-assisted laparoscopic radical prostatectomy.

INTRODUCTION: Weck Hem-o-Lok clip migration into the bladder has been reported after robot-assisted laparoscopic radical prostatectomy (RALP). We report a case of Weck clip migration into the rectum presenting as a mass on colonoscopy. METHODS: A 61-year-old male with a prostate specific antigen level of 4.84 ng/ml underwent transrectal ultrasound guided biopsy of the prostate revealing a Gleason's 3 + 3 adenocarcinoma of the prostate involving 20% of the sampled tissue for the left apex. He was subsequently treated with a transperitoneal robot-assisted laparoscopic radical prostatectomy and bilateral pelvic lymphadenectomy. Weck Hem-o-Lok clips were used to ligate the prostate vascular pedicles. The vesicourethral anastomosis was performed using a double armed running technique. RESULTS: Final pathology demonstrated a Gleason 4 + 3 pT2cN0Mx adenocarcinoma of the prostate with negative margins. Four lymph nodes were negative for malignancy. No intraoperative complications occurred. Postoperatively, patient was found to have a Weck Hem-o-Lok clip that migrated into his rectum. This was found on colonoscopy performed for diverticular disease of the colon. The clip was removed without complication. CONCLUSIONS: Judicious use of Weck clips during RALP and communication with physicians participating in patient care for those who have undergone RALP is crucial in minimizing complications and avoiding subsequent procedures.
