A gain-of-function mutation in genes coding for the KIT tyrosine kinase receptor plays a pivotal role in the differentiation and proliferation of GISTs. Surgical resection offers the only chance of cure however the consensus opinion from the European Society of Medical Oncology (ESMO) restrict laparoscopic approaches to tumours <2cm in certain anatomical locations provided surgical oncological principles are observed. This study will assess the safety, effectiveness, and functional outcomes of an anatomically-based strategy for the laparoscopic resection of gastric GISTs. Methods All symptomatic gastric GISTs diagnosed during a 5 years period were considered for minimal access surgical resection. Lesions were removed according to a structured anatomical approach. The strategy was designed to conserve the organ and preserve sphincter (lower oesophageal and pyloric) function while adhering to oncological principles. A prospective database included patients’ demographics, clinical features, imaging, procedure type, operative findings, complications, histopathology, immunohistochemistry, mutation status and risk stratification. Clinical and radiological follow-up was recorded. Results Thirty-two (32) cases of suspected gastric GISTs were considered for minimal access resection during the study. Twenty-three patients (72%) underwent a laparoscopic wedge resection, six patients (19%) underwent an extra-gastric anterior resection and three patients (9%) underwent trans-gastric posterior resection. 97% were histologically confirmed GIST, all achieving R0 excision. 97% were disease free at 20 months. Conclusion The authors have demonstrated that an anatomically-based surgical strategy for the laparoscopic resection of gastric submucosal tumours is safe and enjoys an oncological and functional success. This, along with the recognised reduced morbidity associated with minimal access surgery lend support to the notion that laparoscopic surgery might be the preferable approach for small to medium sized gastric GISTs.}
