Abstract
A 61-year-old man visited the hospital because of abdominal fullness and pain. X-ray showed colonic gas in the left lower thorax. Computed tomography (CT) revealed prolapse of the colon, spleen and left kidney into the left thoracic cavity. The patient was diagnosed with diaphragmatic hernia and hand-assisted laparoscopic surgery was performed. Hernia contents were reduced into the abdominal cavity. The defect of diaphragm was repaired by direct suture and covered with polypropylene mesh. The patient has remained asymptomatic since the operation. Hand-assisted laparoscopic surgery is a safe and less-invasive surgical method for Bochdalek hernia in adults.
