Gastric Gastrointestinal Stromal Tumor (GIST) Incidentally Found and Resected During Laparoscopic Sleeve Gastrectomy

Abstract

The incidence of incidental pathology found during laparoscopic bariatric surgery has been estimated to be around 2%, and gastric gastrointestinal stromal tumors (GISTs) have been found in 0.8% of patients, constituting a rather uncommon finding. Safe laparoscopic resection of gastric GISTs is an established procedure and has been described associated to gastric Roux-en-Y bypass for morbid obesity. We discuss one case of a gastric GIST incidentally discovered during laparoscopic sleeve gastrectomy for morbid obesity. The procedure was performed via laparoscopy, and the patient recovered without any complication. Currently, the patient has lost weight according to what was expected, is asymptomatic, and free of disease.

Incidental diagnosis of extra-gastric gastrointestinal stromal tumor: case report

“…MRI adds information about the borders and solid structure of the mass and is confirmed the Basic Clin Sci 2013; 3: 128-131 enhancement seen with CT. In the large tumors, the findings of abdominal imaging may be very complex due to necrosis, hemorrhage, or degenerating components [4,2].…”

“…They typically present as subepithelial neoplasms that are most often located in the stomach and proximal small intestine, but can occur in any portion of the gastrointestinal tract [1,2]. During laparoscopic bariatric surgery, the incidence of incidental pathology found was about 2%, and gastric gastrointestinal stromal tumors have been found in 0.8% of patients, constituting a rather uncommon finding [3].…”

Resección Mixta Laparoscópica Y Endoscópica De Un Tumor Del Estroma Gastrointestinal De La Unión Gastroesofágica

“…Recientemente, este procedimiento también se ha descrito mediante el uso de un solo puerto con la técnica Single Incision Laparoscopic Surgery (SILS) con buenos resultados [21][22][23][24] . Hasta épocas recientes, en nuestra institución el diagnóstico y tratamiento de los GIST se efectuaba bajo condiciones de urgencia o en forma incidental 3,4,[25][26][27] . Actualmente con la amplia disponibilidad de estudios de imagen, la mayoría de los GIST son diagnosticados previamente a la cirugía y su abordaje planificado.…”

“…Actualmente con la amplia disponibilidad de estudios de imagen, la mayoría de los GIST son diagnosticados previamente a la cirugía y su abordaje planificado. Tal como se describe en la literatura, la localización más frecuente de los GIST en nuestros pacientes es el estómago 3,4,26,27 . La mayoría de los GIST gástricos operados en nuestro servicio han sido abordados mediante laparotomía realizando una gran variedad de procedimientos de acuerdo al tamaño y localización del tumor, incluyendo resección en cuña, gastrectomía distal, gastrectomía total y resección intragástrica a través de gastrotomía sobre la cara anterior del estómago.…”

Multiple Primary Gastrointestinal Stromal Tumors Presenting in Jejunum and Ileum

“…The small jejunal GIST was benign. Generally these small tumors are incidental findings detected on endoscopy, radiologic imaging, or during surgery [2,7].…”
