A CASE OF PERSISTENT RETROPERITONEAL ABSCESS CAUSED BY RESIDUAL SILK SUTURE AFTER SURGERY

Abstract

A 61-years-old male with left renal cancer and ipsilateral adrenal tumor had carried out partial nephrectomy and adrenalectomy via open retroperitoneal approach. Fourteen days after surgery, febrile reaction occurred and CT revealed an abscess developed in the retroperitoneal space. Open drainage and lavage of retroperitoneal space had performed, and irrigation of drainage tract had been continued for persistent flow of purulent discharge from abscess touching upper pole of the kidney for about 4 months. After 127 days of second surgery, two clusters of silk suture were sucked out during irrigation. Soon after the episode, flood of purulent discharge from drainage tract was ceased and retroperitoneal abscess was diminished drastically. It should be in mind that the foreign boy like silk suture used during surgery would cause persistent retroperitoneal abscess.
