Outcomes and Use of Laparoscopic Versus Open Gastric Resection

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Gastrointestinal Surgery

Background:

• Laparoscopic surgery offers advantages over open procedures.
• Laparoscopic resection for gastric cancer is oncologically equivalent to open resection.
• Gastric cancer treatment outcomes are comparable between laparoscopic and open approaches.

Purpose of the Study:

• To assess the utilization of laparoscopy in treating gastric cancer.
• To evaluate the outcomes associated with laparoscopic versus open gastric cancer resection.

Main Methods:

• Utilized the American College of Surgeons National Surgical Quality Improvement Project (NSQIP) dataset (2005-2012).
• Analyzed data for patients with gastric cancer (ICD-9: 151.0-151.9).
• Employed logistic regression to compare 30-day morbidity and mortality between open (CPT: 43620-2, 43631-4) and laparoscopic (CPT: 43650) gastrectomy, adjusting for risk factors.

Main Results:

• Identified 4116 gastric cancer patients: 3725 (90.5%) open, 391 (9.5%) laparoscopic.
• Laparoscopic resection demonstrated significantly lower complication rates (OR 0.61; P = .001) after risk adjustment.
• No significant difference in 30-day mortality was observed between laparoscopic and open gastric resection (OR 0.74; P = .481) after risk adjustment.

Conclusions:

• Laparoscopy is currently underutilized in gastric cancer treatment.
• Laparoscopic gastric resection is associated with reduced morbidity compared to open resection.
• Increased adoption of laparoscopy for gastric cancer is recommended to improve patient outcomes.
