[Splenic flexure mobilization in surgery for rectal cancer]

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Rectal Cancer Treatment

Background:

• Splenic flexure mobilization (SFM) is a surgical step in anterior and low anterior resections for rectal cancer.
• Its necessity is debated due to conflicting evidence on its impact on surgical outcomes.

Purpose of the Study:

• To review the current literature on the necessity and benefits of splenic flexure mobilization in rectal cancer surgery.
• To evaluate the impact of SFM on tension-free anastomosis, specimen length, lymph node yield, anastomotic leakage, and long-term oncologic outcomes.

Main Methods:

• Literature review of studies investigating splenic flexure mobilization in anterior and low anterior rectal resection.
• Analysis of reported outcomes including anastomotic leakage rates and oncologic results.

Main Results:

• There is no established agreement in the literature regarding the routine use of SFM.
• Evidence does not consistently support reduced anastomotic leakage or improved long-term oncologic outcomes after SFM.
• A selective approach to SFM is gaining traction.

Conclusions:

• The routine use of splenic flexure mobilization in rectal cancer surgery is not definitively supported by current evidence.
• Randomized trials are required to establish the indications for selective SFM versus routine SFM.
