Objective:
To assess the feasibility and safety of laparoscopic rectal surgery without abdominal scar.
Methods:
A total of 23 patients of rectal cancer were operated by laparoscopy with the assistance of PPH (procedure for prolapse and hemorrhoids) anal expander and TEM (transanal endoscopic microsurgery) outer-shell according to the principle of TME (total mesorectal excision).
Results:
All operations were successfully accomplished laparoscopically. There was no conversion into an open procedure. The average operative duration was 129 (105 - 211) minutes. The intra-operative blood loss volume was 152 (85 - 420) ml. No immediate or delayed injury of urinary duct and other intra-operative severe complications, such as massive hemorrhage of presacral venous plexus, occurred. There was no pelvic infection or anastomotic stoma fistula during the post-operative period. The average follow-up period was 13.4 months. Neither anastomotic stoma recurrence nor Trocar implantation occurred.
Conclusion:
The laparoscopic technique of hybrid NOTES (Natural Orifice Transluminal Endoscopic Surgery), plus PPH/TEM is both feasible and convenient for selective rectal cancer surgery. There is no need for extra abdominal incision. It is recommended for laparoscopic rectal surgery.
