Abstract
Situs inversus totalis (SIT) is a rare anomaly in which the thoracic and abdominal organ’s position is mirror image of normal anatomy. Due to the mirror position and vascular abnormalities, laparoscopic surgery for patients in SIT is considered difficult. We here report a patient with SIT who underwent laparoscopic sigmoidectomy for sigmoid cancer. The operation surgeon stood on the patient’s left side, opposite the normal location for laparoscopic sigmoidectomy, while medial to lateral approach. During the rectal dissection and anastomosis, the surgeon's position was changed from the left side to the right side of the patient. Because the location of the pelvis is almost the same as the normal anatomy, the operation was performed like that of a normal dissection. The operation time was 221 minutes with almost no blood loss. There was no postoperative complication, and the patient left the hospital 10 days after surgery. Laparoscopic surgery can be performed safely even in SIT, by effectively changing the position of the operator.
