An Alternative Abdominal Closure Technique After Pediatric Liver Transplant: Bogota Bag Technique

In conditions such as large-for-size syndrome, postreperfusion hepatic edema, and intestinal edema, primary closure of the abdominal wall can cause respiratory complications and thrombosis of vascular structures. Here, we compared results of primary abdominal closure versus a temporary patch closure technique (the Bogota bag technique) in pediatric liver transplant recipients.

We performed primary abdominal closure in 295 recipients. In 39 pediatric liver transplant recipients, the Bogota bag technique was used as the abdominal closure technique because of suspected intraoperative tense abdominal closure. In patients who had the Bogota bag technique, we sutured the sterilized saline bag to the skin at the edge of the defect by shaping the defect so as not to cause abdominal hypertension. Primary abdominal closure was achieved in patients after control laparotomies at 48-hour intervals.

The mean age of the primary abdominal closure group was 8.38 years, whereas the mean age of the Bogota bag group was 2 years. The average weight of patients in the primary abdominal closure group was 26.38 kg, and the average weight of patients in the Bogota bag group was 7.93 kg. Biliary atresia was the most common indication in both groups. Mean length of hospital stay was 21 days in the primary abdominal closure group and 24 days in Bogota bag group. Six patients in the Bogota bag group died from sepsis or bleeding in the early postoperative period. In the Bogota bag group, wound closure was achieved within 2 weeks in 25 patients and within 3 weeks in 8 patients.

Temporary patch closure techniques can be used safely in low-weight and young children, children with large-for-size grafts, and those who display increased intra-abdominal pressure.
