Abstract
The components separation technique is a method used for abdominal wall reconstruction in patients with midline hernias that cannot be closed primarily. In the present report, we describe a case of abdominal wall reconstruction using the components separation technique after resection of invasive sigmoid colon cancer.
A 64-year-old man presented with pollakiuria and hypogastric pain. An examination indicated the presence of a 15-cm mass in the lower abdomen, along with discharge from the umbilicus. Colonoscopy findings suggested a diagnosis of circular, type 2, advanced colon cancer. Abdominal CT showed extensive thickening of the sigmoid colon, with invasion of the small intestine, urinary bladder, and abdominal wall. Sigmoidectomy with partial resection of the small intestine, cyst prostatectomy, creation of an ileal neobladder, and resection of the abdominal wall were performed. The abdominal wall defect was 10×10 cm in size, and was reconstructed using the components separation technique ; the external oblique muscle was released and advanced over the defect of the rectus muscle. The patient's postoperative course was uneventful, the outcome was satisfactory, and the patient was discharged at postoperative day 30. The patient has remained in good health without any cancer recurrence or abdominal wall hernia at 2 years after surgery.
