[Laparoscopic rectal excision for cancer using total mesorectaol excision (TME). Long term outcome of a series of 179 patients].
BACKGROUND
The purpose of this study was to evaluate the outcomes and the five-year survival of 179 consecutive patients with rectal carcinoma operated with a laparoscopic procedure between April 1992 and April 2003.


METHODS
Patients with obstructing, bulky cancers were excluded from this study. Tumor stage was defined according to the TNM classification. Preoperative radiation therapy was offered to T(3) N(0) or N(+) patients (45 Gy). The laparoscopic-assisted technique included total mesorectal excision (TME), primary high vascular ligation, centrifugal dissection of the mesentery, and "no touch" technique. All the N+ patients received adjuvant chemotherapy. The outcomes were defined as five-years recurrence (local recurrence and distant metastasis) and the diseases-free survival. The survival rates were calculated with the Kaplan-Meier test.


RESULTS
There were 108 males and 71 females, median age was 67 (range 39-88). There were 61 upper rectum localizations (34%), 68 middle rectum (38%) and 50 low rectum (28%). Twenty-nine patients required open conversion (16%). Surgical operative morbidity was 24% and medical morbidity was 4%. There were 60 stage I (40%), 25 stage II (16%), 49 stage III (32%), and 16 stage IV (10%). Ninety patients (71%) are alive and disease free, ten (5%) are alive with disease recurrence, and 37 patients (20%) are deceased. Only one case of trocar site implantation occurred after curative resection during an average follow up of 76 months. Five-year observed survival rate were 85% for stage I, 70% for stage II, and 63% for stage III.


CONCLUSIONS
In our experience laparoscopic rectal resection could be done safely. The oncologic outcome was similar to that of open surgery. Further randomized trials will be necessary to confirm the value of this technique.
