Purpose:
While a
carcinoma of the
splenic flexure is uncommon, is associated with a high
risk of obstruction, and has a dual lymphatic
drainage system, A
COST study excluded
transverse colon cancer, including
splenic flexure colon cancer. This study reviews our experience with
splenic flexure colon cancer treated laparoscopically and discusses a appropriate, safe
laparoscopic surgical procedure.
Methods:
The authors reviewed the
medical records of
patients who underwent
laparoscopic surgery for
splenic flexure colon cancer from January 1995 to June 2006. The
splenic flexure colon was defined as 5 cm from the
splenic flexure proximally and distally by using radiologic studies. Curative
surgery for
splenic flexure colon cancer was defined as primary
cancer removal, a safe resected margin, no
metastasis, and a complete
lymphadenectomy including high
ligation of left
colic artery and of the left branch of the middle
colic artery.
Results:
A total of 407
patients underwent
laparoscopic surgery for
colon cancer; among them, 15
patients underwent a laparoscopic left
colectomy for
splenic flexure colon cancer. The mean age of the
patients was 63.8 years, and the
male-to-
female ratio was 96. The mean operation
time was 325.3+/-95.1 minutes, and the average
hospital stay was 15.8+/-4.9 days. The average number of harvested
lymph nodes was 12.3+/-9.7, the average distal
resection margin was 15.3+/-7.6 cm, and the average proximal margin was 10.7+/-3.2 cm. One case of
chyle discharge and one case of
ileus developed, but were treated conservatively. There was no surgical
mortality.
Conclusions:
A laparoscopic left
colectomy for
splenic flexure colon cancer is a technically feasible and safe
procedure with acceptable short-term outcomes in experienced
hands.
