A current status of laparoscopic bowel surgery for cancer in Japan was investigated with collaboration of the majority of main hospital in the country and by sponsership of Japanese society for cancer of colon and rectum.
81 of 113 (71.7%) main surgical departments in Japan have introduced this procedures in practice since 1993.
A total of 958 cases in the last 3 years (1994-1996) have been treated by this procedure and this number indicates 7% of all surgically treated cases of the colorectal cancer during the same peirod.
796 of 958 cases (83%) were the early cancers without lymphnodes involvement. The laparoscopic bowel surgery has been generally indicated for the cancer in early stage.
The cases converted from this procedure to usual open surgery were 54 (conversion rate is 6%). The main reason for conversion was technical difficulty due to intraabdominal dense adhesions.
There were the early postoperative complications including, in 70 cases, local subcutaneus abscess in the place where the trockers were inserted at the time of laparoscopic surgery, anastomotic leakage in 18 cases, local bleedings in 13 cases, bowel obstructions with adhesions in 14 cases and port-site-hernia in 6 cases.
