Laparoscopic Complete Mesocolic Excision for Double Flexural Colon Cancers.

Area of Science:

• Colorectal surgery
• Surgical oncology
• Minimally invasive surgery

Background:

• Laparoscopic complete mesocolic excision (CME) for hepatic or splenic flexural colon cancer is technically challenging.
• Double flexural colon cancers (involving both hepatic and splenic flexures) are rare.
• Standardization of laparoscopic CME for these rare cases is lacking.

Observation:

• A video presentation of laparoscopic CME for double flexural colon cancers using a medial and cranial approach.
• The procedure involved laparoscopic subtotal colectomy with specific steps for vessel ligation and mesocolic dissection.
• The specimen was extracted via umbilical incision, followed by extracorporeal ileo-sigmoid anastomosis.

Findings:

• The described medial and cranial approach facilitates laparoscopic CME for double flexural colon cancers.
• The technique allows for meticulous lymph node dissection along the surgical trunk.
• Successful completion of CME and anastomosis was achieved in the presented case.

Implications:

• The presented laparoscopic CME technique offers a potential method for standardizing surgical procedures for rare double flexural colon cancers.
• This approach may improve the feasibility and reproducibility of minimally invasive surgery for complex colorectal conditions.
• Further adoption of this technique could enhance oncologic outcomes in patients with these rare tumors.
