Surgical Drain-Related Intestinal Obstruction After Robot-Assisted Laparoscopic Radical Prostatectomy in Two Cases.

Drainage tubes are almost always routinely used after a laparoscopic or robot-assisted radical prostatectomy and pelvic lymphadenectomy to prevent urinoma formation and lymphoceles. They are seldom of any consequence. We present our unique experience of bowel obstruction resulting from the use of pelvic drains. We are reporting on two prostate cancer cases with rare postoperative complications. Each of them received robot-assisted laparoscopic radical prostatectomy and bilateral pelvic lymph node dissection and subsequently developed ileus and bowel obstruction. Series follow-up images suggested the bowel obstruction was related to their drainage tube. No evidence of urine leakage or intestine perforation was found based on drainage fluid analysis. We performed exploratory laparotomy in the first patient and found drainage tube kinking with the terminal ileum and adhesion band. The drainage tube was removed and patient recovery occurred over the following days. In the second case, the patient experienced bowel obstruction for 4 days after surgery. Based on our experience in the first case, and a drainage fluid survey showing no evidence of urine leakage, we removed the drainage tube on the morning of the 4th day, giving the patient a dramatic recovery with flatus and stool passage occurring in the afternoon. Both of the patients recovered well in hospital and during regular follow-up. To best of our knowledge, despite there being certain case reports regarding drainage tube ileus in colorectal and bowel surgery, we have reported here on the first two cases of small bowel obstruction as a complication arising from the abdominal drainage tube used in robot-assisted urology surgery.
