Abstract
The patient was a 75-year-old man who had bilateral inguinal hernias. In the left scrotum a sigmoid colon had herniated and a hard tumor was palpated within the scrotum. Although reduction of the colon to the abdomen was difficult, he had no pain relating to the herniation and an abdominal CT scan showed favorable enhancement effect. We thus considered the circulatory disturbance to be absent and electively performed laparoscopic radical sigmoidectomy. Following lymph node dissection, treatment of mesentery of the colon, and transection of the proximal and sidtal sides of intestine under laparoscopy, a skin incision was made on the inguinal region and the sigmoid colon with the hernia sac which remained covering it was removed. The postoperative course was uneventful and the patient was discharged from the hospital on the 11th postoperative day.
This patient had a tumor which is classified into intrasaccular tumors. The tumors have been reported to be common on the left side as for sigmoid colon cancer and on the right side as for cecal cancer. We present our experience with the case in which intrasaccular tumor caused by sigmoid colon cancer was diagnosed preoperatively and laparoscopic sigmoidectomy was performed.
