Laparoscopic surgery for pancreatic lesions: current status and future

Area of Science:

• Minimally Invasive Surgery
• Surgical Oncology
• Gastrointestinal Surgery

Background:

• Laparoscopic pancreatic surgery is gaining recognition due to its minimally invasive nature.
• Techniques like laparoscopic distal pancreatectomy and tumor enucleation are becoming more common.
• These procedures are complex with a steep learning curve compared to other abdominal surgeries.

Purpose of the Study:

• To review the current status and indications of laparoscopic pancreatic surgery.
• To evaluate the safety and efficacy of laparoscopic approaches for pancreatic lesions.
• To identify the need for further clinical trials comparing laparoscopic and open pancreatic surgery.

Main Methods:

• Literature review of existing studies on laparoscopic pancreatic surgery.
• Analysis of current practices and outcomes for laparoscopic distal pancreatectomy, enucleation, and pancreaticoduodenectomy.
• Assessment of the evidence for benign, low-grade malignant, and malignant pancreatic tumors.

Main Results:

• Laparoscopic distal pancreatectomy and enucleation are safe and effective for benign and low-grade malignant tumors.
• The use of these techniques is increasing due to their relative technical simplicity.
• Indications for laparoscopic surgery in malignant pancreatic tumors remain controversial.
• Laparoscopic pancreaticoduodenectomy is performed in limited centers, with feasibility demonstrated but clinical benefits over open surgery unproven.

Conclusions:

• Laparoscopic distal pancreatectomy and enucleation are established procedures for specific pancreatic conditions.
• Further high-quality evidence, particularly from prospective randomized controlled trials, is required to validate laparoscopic pancreatic surgery for all pancreatic lesions, especially malignant ones.
• Comparative studies are essential to determine if laparoscopic approaches offer advantages over traditional open surgery.
