Abstract
Diaphragmatic hernias (DH) occurring after pediatric liver transplantation (LT) are rare. However, such complications have been previously reported in the literature and treatment has always been surgical repair via laparotomy. We report our experience of minimally invasive thoracoscopic approach for repair of DH occurring after LT in pediatric recipients.
From April 2010 to December 2014, 7 cases of DH were identified in pediatric LT recipient in Samsung Medical Center. Thoracoscopic repair was attempted in 3 patients. Patients’ medical records were retrospectively reviewed.
Case 1 was a 12-month-old boy, having received deceased donor LT for biliary atresia (BA) 5 months ago. He presented with dyspnea and left-sided DH was detected. Thoracoscopic repair was successfully done and the boy was discharged at postoperative day 7. Case 2 was a 13-month-old boy, having received deceased donor LT for BA 2 months ago. He presented with vomiting and right-sided DH was detected. Thoracoscopic repair was done along with primary repair of herniated small bowel that was perforated while attempting reduction into the peritoneal cavity. The boy recovered from the surgery without complications and was discharged on the 10th postoperative day. Case 3 was a 43-month-old girl, having received deceased donor LT for Alagille syndrome 28 months ago. She was diagnosed with right-sided DH during steroid pulse therapy for acute rejection. Thoracoscopic repair was attempted but a segment of necrotic bowel was noticed along with bile colored pleural effusion and severe adhesion in the thoracic cavity. She received DH repair with small bowel resection and anastomosis via laparotomy.
Thoracoscopic repair was attempted in 3 cases of DH occurring after LT in pediatric recipients. With experience and expertise in pediatric minimally invasive surgery, thoracoscopic approach is feasible in this rare population of patients.
