Laparoscopy for gastric tumors

Abstract

A decade after the introduction of therapeutic laparoscopy, the use of laparoscopic gastric surgery is becoming accepted. While still evolving, currently available techniques and equipment are already sufficient for performing most ablative and reconstructive procedures. Despite feasibility, problems such as procedural complexity, long operative time, and high cost may negate the advantages of earlier and easier recovery. At present, these procedures are limited to highly trained laparoscopic surgeons, but they may become more prevalent among the next generations of surgeons, due to constant changes in surgical training and education. The question of laparoscopic curative treatment of malignant gastric tumors has not been answered. Diagnostic laparoscopy for staging is effective and widely practiced, but gastric resections are mostly limited to benign lesions. Currently, early malignant lesions are laparoscopically treated mainly in Japan, whereas more advanced lesions are laparoscopically resected in only a few centers around the world. Full endorsement of these procedures, by randomized controlled trials, although desirable, is unlikely soon, due to the technical complexity and low prevalence of these pathologies in western countries.
