Abstract

Background

The surgical approach to the colonic splenic flexure cancer (SFC) is yet to be technically standardized. The aim of this study has been to retrospectively evaluate the oncologic long-term results of our cases comparing our data with other authors’ experiences.

Methods

Clinical data of patients with SFC operated on at our institute were retrospectively analyzed. The laparoscopic approach was used in the whole series, with limited resection distally and proximally to splenic flexure and the origin ligation of left colic artery and left branch of middle colic artery. Data on the oncological long-term safety were compared to our laparoscopic series of extended right colectomy for proximal two-third transverse colon cancer and high anterior resections for sigmoid-high rectal cancer and to the main evidences in the literature, found after a comprehensive review.

Results

From March 2008 to May 2018, we completed 53 laparoscopic splenic flexure resections (26 female and 27 male, age 71.5 ± 15.4 years). The conversion rate was 3.8%. Most of the cases were stage II (pT3 73.5%, the mean number of lymph nodes harvested was 19.1, with positivity for malignancy in 45.3%). During the FU (43.5 months), 2 patients dropped out. Out of the 51 residual cases, 37 were alive (72.5%) and 14 are deceased (27.5%).

Discussion

Compared to the literature, our survival rate does not show significant differences. The other oncological outcomes seem to be comparable with the data evaluated.

Conclusions

More extended resections seem not to confer an increase of the overall survival rate.
