Complications with laparoscopically assisted gastrectomy: multivariate analysis of 300 consecutive cases

Area of Science:

• Gastroenterology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Complications of laparoscopically assisted gastrectomy (LAG) are comparable to open gastrectomy.
• LAG presents unique risks including those from abdominal access, pneumoperitoneum, and electrosurgical instruments.
• This study investigates the causes and risk factors for postoperative morbidity following LAG.

Purpose of the Study:

• To analyze the causes and risk factors associated with postoperative morbidity after laparoscopically assisted gastrectomy (LAG).
• To evaluate the perioperative complication rates and identify predictors of patient outcomes in LAG procedures for gastric cancer.

Main Methods:

• Retrospective review of 300 consecutive patients undergoing LAG for gastric cancer (May 2003 - October 2006).
• Data included patient demographics, comorbidities, surgical details (type, operative time, lymph node dissection), and outcomes (mortality, morbidity, hospital stay).
• Patients were divided into two operative periods to assess learning curve effects.

Main Results:

• Overall postoperative complications occurred in 20.3% of patients.
• Common complications included wound infection (7%), stenosis (4.3%), and bleeding (4%).
• Multivariate analysis identified comorbidity and operative period as significant risk factors for complications.

Conclusions:

• Laparoscopically assisted gastrectomy (LAG) can be performed with acceptable perioperative complication rates.
• Surgeon experience, reflected in the operative period, is a crucial factor in minimizing complications.
• Careful patient selection is essential for achieving optimal outcomes in LAG for gastric cancer.
