Background:
Routine splenic flexure mobilization (SFM) during left hemicolectomy and high anterior rectal resection guarantees a well perfused and tension-free anastomosis, respecting current oncological criteria. According to the recent literature, only 70% of laparoscopic colorectal surgeons considered routine SFM mandatory. Because of its difficulty, SFM increases morbidity including surrounding organs injuries. The goal of the study is to report our experience in avoiding routine SFM during colorectal resection compared to the current surgical state of art.
Methods:
Data were collected retrospectively on elective left hemicolectomy without routine SFM performed in our unit between January 2015 to April 2020. Patients were recruited according to diagnosis, histopathology, operative time, ASA score, post-operative morbidity and mortality.
Results:
Seventy-five oncological patients, underwent to surgery without SFM. The other 13 patients underwent to SFM due to technical issues. The mean operative time was 160.2±44.7 mins, significantly shorter than in patients whose SFM occurred (210.3 min). The morbidity rate was 1%, reintervention occurred in one patient. Eighteen-month median follow-up morbidity was 11% while mortality was 3%. Recurrence rate was of about 5%.
Conclusions:
As results from study data analysis, left colectomy can be conducted safely in both laparoscopic and laparotomic approach without SFM in selected cases. As reported in a recent meta-analysis, benefits of avoiding SFM concern reduced operative time without compromising postoperative outcome and respecting oncological criteria, as emerged by our results. Colorectal resection without SFM when is feasible, improves surgical approach reducing technical difficulties and avoiding splenic injuries.
