Percutaneous transhepatic duodenal drainage is good option for afferent loop syndrome for obstructive colorectal cancer patient with history of Billroth's operation II: A case report of a rare postoperative complication.

Key Clinical Message: Temporal percutaneous transhepatic duodenum drainage (PTDD) seems to be effective in the treatment of postoperative afferent loop syndrome (ALS) following transverse loop colostomy for obstructive colorectal cancer. Abstract: Management of obstructive colorectal cancer still remains a challenge. There are various options with different risks of mortality and mobility for obstructive colorectal cancer. A rare unexpected postoperative ALS following a low anterior resection and transverse loop colostomy for obstructive colorectal cancer is presented in this report. A 64-year-old man had the acute ALS had been noted 10 days after transverse loop colostomy. An option was temporal PTDD treatment in the patient with history of Billroth's operation II for upper gastrointestinal bleeding 30 years ago. Acute ALS was treated by temporal PTDD. The drainage tube for PTDD was not removed until closure of the transverse colostomy 2 months later. The patient recovered uneventfully. Acute ALS after transverse loop colostomy for obstructive colorectal cancer is rare and has never been reported in the literature. The mechanism of acute ALS after construction of a loop colostomy and the treatment strategy of PTDD for acute ALS is presented.
