Left colectomy with intracorporeal anastomosis: technical aspects

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Minimally Invasive Procedures

Background:

• Laparoscopic colectomy is validated for colorectal cancer.
• Laparoscopic surgery for distal transverse/descending colon is challenging.
• Total laparoscopic left colectomy is an option for critically ill patients but lacks standardization.

Purpose of the Study:

• To describe a technique for total laparoscopic left colectomy.
• To address challenging distal transverse and descending colon lesions.
• To highlight benefits of a standardized laparoscopic approach.

Main Methods:

• Detailed description of a total laparoscopic left colectomy technique.
• Focus on intracorporeal vessel sealing for lymph node dissection.
• Emphasis on creating a well-vascularized anastomosis and minimizing abdominal incision.

Main Results:

• The technique facilitates adequate lymph node dissection.
• Enables construction of a well-vascularized anastomosis.
• Potentially reduces late wound complications via a single low abdominal incision for specimen extraction.

Conclusions:

• Total laparoscopic left colectomy is a feasible and advantageous approach for specific colorectal cancer cases.
• The described technique offers benefits in oncologic clearance and patient recovery.
• Further standardization and reporting are needed for this selective procedure.
