Laparoscopic techniques and strategies for gastrointestinal GISTs

Area of Science:

• Gastroenterology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Laparoscopic surgery is a widely accepted treatment for gastrointestinal submucosal tumors (SMTs).
• Tumor size influences the indication for laparoscopic approaches, with increasing upper limits and no established lower limit.
• Preoperative assessment is crucial, involving endoscopy, radiography, CT, and EUS.

Purpose of the Study:

• To introduce laparoscopic techniques and strategies for gastrointestinal SMTs.
• To align techniques with those used for gastrointestinal stromal tumors (GISTs).
• To detail methods for tumor localization and resection while ensuring negative margins.

Main Methods:

• Preoperative localization of gastric tumors (<20 mm) using gastrofiberscopic clipping.
• Application of diverse surgical techniques based on tumor location and configuration.
• Implementation of a "no-touch" technique to minimize tumor dissemination during resection.

Main Results:

• Laparoscopic resection with negative margins is achievable for gastrointestinal SMTs.
• The "no-touch" technique aids in minimizing the risk of tumor dissemination.
• Antibiotic prophylaxis and tailored postoperative diets are standard care.

Conclusions:

• Laparoscopic surgery offers a viable approach for gastrointestinal SMTs.
• Careful preoperative planning and specialized techniques like "no-touch" are essential for successful outcomes.
• Surgical strategy should be adapted to individual tumor characteristics.
