During treatment for sigmoid colon diverticulitis, a 72-year-old man underwent abdominal computed tomography, which revealed a gastric tumor that was approximately 40mm in diameter. He then underwent a detailed examination after the remission of diverticulitis. The gastric mucosa was found to be unremarkable on gastrointestinal endoscopy. On ultrasonic endoscopy, however, a hypoechoic mass of approximately 40mm in diameter was detected in the fourth layer of the gastric fornix and was believed to be a gastric submucosal tumor(SMT)...

Laparoscopic and endoscopic cooperative surgery (LECS) is increasingly applied for gastric submucosal tumors (SMTs) such as gastrointestinal stromal tumors. However, the conventional LECS procedure has the potential risk that gastric contents and even tumor cells could spread into the abdominal cavity because the gastric wall has to be opened during the resection. To avoid this problem, we have developed a modified LECS procedure named "closed LECS." Ten patients underwent closed LECS for the resection of gastric SMTs...

BACKGROUND: Laparoscopic endoscopic cooperative surgery (LECS) is a safe alternative to endoscopic submucosal dissection (ESD) for select gastric gastrointestinal stromal tumors (GISTs) that are <2 cm in size. To date, there have been no randomized studies comparing the feasibility of these two techniques. Therefore, we compared their feasibility and safety using the propensity score matching method in this study. METHODS: This was a single-center, retrospective, propensity score-matched study of patients who underwent resection of selected gastric GISTs between 2004 and 2014...

The typical treatment of choice for gastrointestinal stromal tumors (GIST) is surgical resection. Here we report a case of three GIST lesions resected safely by laparoscopic-endoscopic cooperative surgery (LECS). A 78-year-old woman was referred to our hospital for further treatment of an enlarging gastric submucosal tumor. Esophagogastroduodenoscopy and endoscopic ultrasonography revealed two gastric submucosal tumors. Endoscopic ultrasonography-guided fine needle aspiration was subsequently performed. The patient underwent LECS in accordance with therapeutic guidelines for GIST...

Gastrointestinal stromal tumors (GISTs) are the most common primary mesenchymal neoplasms of the gastrointestinal tract and usually appear as a well-circumscribed mass. However, it may be difficult to confirm the extent of the disease for some GISTs. A 70-year-old asymptomatic female presented for a regular physical exam. An esophagogastroduodenoscopy showed a 2.0 cm protruding mass on the gastric fundus. Endoscopic ultrasound revealed an ill-defined heterogenous hypoechoic lesion (3.0×1.5 cm). A computed tomography (CT) scan demonstrated a 4...

Laparoscopic wedge resection of the stomach is a widely accepted treatment for primary resectable gastrointestinal stromal tumors (GISTs). However, it is difficult to determine the appropriate incision line from outside of the stomach, and many attempts have been made to avoid unnecessary resection of unaffected gastric tissues. Recently a technique called non-exposed endoscopic wall-inversion surgery (NEWS) was introduced to avoid exposure of GIST to the peritoneum. Here, we describe the first published case of NEWS for GIST of the stomach practiced in Korea...

PURPOSE: Complete surgical resection with negative margins without lymphadenectomy is the treatment of choice for nonmetastatic Gastrointestinal Stromal Tumors (GISTs). Laparoscopic resection of gastric GISTs <5 cm is an acceptable and oncologically feasible, safe, and effective treatment. We present our experience of an endoscopically assisted minimally invasive transumbilical single-incision laparoscopic (SILS) technique for gastric GISTs resection. METHODS: Four patients with small gastric GISTs ≤5 cm located on the greater curvature or the anterior wall were resected with SILS by using a lesion-lifting technique under the guidance of flexible gastroscopy...

Recently, several studies have reported local full-thickness resection techniques using flexible endoscopy for gastric tumors, such as gastrointestinal stromal tumors, gastric carcinoid tumors, and early gastric cancer (EGC). These techniques have the advantage of allowing precise resection lines to be determined using intraluminal endoscopy. Thus, it is possible to minimize the resection area and subsequent deformity. Some of these methods include: (1) classical laparoscopic and endoscopic cooperative surgery (LECS); (2) inverted LECS; (3) combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique; and (4) non-exposed endoscopic wall-inversion surgery...
