We performed laparoscopic colectomy in 543 patients for descending colon to rectal cancer. We experienced 13 patients with abnormality of sigmoid colon fixation which is so-called persistent descending mesocolon(PDM). Character of PDM is adhesion between the sigmoid colon to the mesentery and pelvic wall. PDM can be classified into long-S type and short-S type with or without adhesion to the descending colon. Careful dissection is necessary to prevent injury of the marginal vessels of the descending colon because this mesocolon is shortened. Comparing PDM and normal sigmoid colon, there was a significant difference in operating time and blood loss. However, there were no differences in postoperative hospital stay. Laparoscopic colectomy is safe even for patients with PDM.
