Laparoscopic vs. open resection for colorectal adenocarcinoma

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Laparoscopic surgery is increasingly adopted for various procedures.
• Its application in colorectal adenocarcinoma resection requires outcome evaluation.
• Comparison with traditional open surgery is essential for evidence-based practice.

Purpose of the Study:

• To compare the outcomes of laparoscopic versus open resection for colorectal adenocarcinoma.
• To assess differences in postoperative recovery, complications, and long-term survival.

Main Methods:

• Retrospective cohort analysis of patients undergoing elective resection for colorectal adenocarcinoma.
• Comparison of 219 open resections with 98 laparoscopic resections.
• Intention-to-treat principle applied for converted laparoscopic cases.

Main Results:

• Laparoscopic resection showed significantly shorter times to first flatus, bowel movement, and diet resumption.
• Patients undergoing laparoscopic surgery experienced shorter hospitalizations and less parenteral analgesic use.
• Minor postoperative complications were fewer in the laparoscopic group, with similar major complication rates.
• Recurrence, disease-free, and overall survival rates were comparable between both techniques.

Conclusions:

• Laparoscopic resection for colorectal cancer is safe and effective in tertiary centers.
• Advantages include earlier discharge, quicker resumption of oral intake, and reduced postoperative pain.
• No negative impact on recurrence or survival was observed, but further randomized trials are recommended.
