A pen in the liver
Abstract
A 24-year-old woman with anxiety, depression, and emotionally unstable personality disorder was referred to a tertiary center 2 weeks after ingesting multiple foreign bodies. She had undergone a laparoscopic cholecystectomy and a laparotomy for extraction of ingested foreign bodies several years ago. A sagittal CT scan view showed a ballpen and a hair clip in the stomach. A coronal view demonstrated that a second ballpen had penetrated the duodenal wall to enter the liver parenchyma. There was no free intraperitoneal air or fluid or evidence of abscess formation. At laparotomy, a toothbrush, a broken spoon and a ballpen were extracted from the stomach via an anterior gastrotomy. The duodenum was adherent to the liver but the second ballpen had migrated into the distal duodenum, with the tip in the proximal jejunum. This was extracted via an enterotomy and the fistula was not interfered with. The enterotomy and gastrotomy were closed with 3-0 polydioxanone sutures. The hair clip had passed spontaneously and was not detected on intraoperative fluoroscopy. She made an uneventful recovery and postoperative liver function tests remained in the normal range. This is only the fourth reported case of a pen fistulizing between the upper gastrointestinal tract and the liver.
