Gastrointestinal stromal tumors (GISTs) of the stomach presenting as an intra-abdominal abscess are extremely rare. We herein report a case that underwent successful laparoscopic resection of gastric GIST presenting with an intra-abdominal abscess. A 70-year-old man presented with a 3-day history of acute upper abdominal pain with a fever. Laboratory data showed an elevated white blood cell count and C-reactive protein level. A CT scan revealed a mass of mixed solid and fluid components, measuring 5.5 cm, in the adjacent lesser curvature of the stomach...

The current tissue sampling techniques for subepithelial tumors (SETs) of the gastrointestinal (GI) tract have limited diagnostic efficacy. We evaluated the diagnostic yield and safety of forceps biopsies after small endoscopic submucosal dissection (SESD biopsies) in the diagnosis of gastric SETs. A total of 42 patients with gastric SETs > 10 mm were prospectively enrolled between May 2013 and October 2014. A dual knife was used to incise the mucosa and submucosa and forceps biopsies were then introduced deep into the lesion...

Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms that arise in the gastrointestinal tract, accounting for ~1% of gastric malignancies. The present study reports the case of a GIST of the stomach in a 75-year-old man who presented with abdominal distension and anorexia for 1 month. Gastroscopy was unremarkable. Ultrasound and computed tomography (CT) scans showed a giant intraabdominal cystic lesion of unknown origin. The lesion was initially believed to be a duplication cyst, a pancreatic pseudocyst or a liver cyst in the pre-operative diagnosis...

INTRODUCTION: Gastrointestinal stromal tumor (GIST) is the commonest mesenchymal tumor of GI tract and 60-70% of it seen in the stomach, whereas Gastric schwannoma is a benign, slow growing and one of the rare neoplasms of stomach. Age distribution, clinical, radiological features and gross appearance of both tumors are similar. PRESENTATION OF CASE: We report a rare case of gastric schwannoma in a 20-year-old girl, who underwent subtotal gastrectomy with the suspicion of a GIST preoperatively but later confirmed to be gastric schwannoma postoperatively after immunohistochemical study...

Adenocarcinomas are the most common cancers affecting stomach. However gastrointestinal stromal tumors (GIST), lymphomas and neuroendocrine tumors (NETs) can also affect the stomach. But stomach is relatively rare site of involvement by metastasis. In this case report a rare metastasis of germ cell tumor (GCT) into stomach is described which clinically and endoscopically masquerade as primary gastric cancers. But detailed clinical examination and vigilant histopathological reporting proves the origin of tumor distant from stomach and thereby change the whole approach of management...

BACKGROUND: Surgical resection is considered to be the best treatment for gastrointestinal stromal tumor (GIST), the most common mesenchymal tumor of the gastrointestinal tract. Tumor size, mitotic rate, and anatomic locations are directly related to the potential malignancy, surgical approach, oncological treatment, and recurrence rate. MATERIALS AND METHODS: This was a retrospective study of 40 patients who underwent surgical resection of histologically or immunohistochemistry-proven GIST of the stomach at the Rabin and Kaplan Medical Center between 2004 and 2013...

BACKGROUND: Laparoscopic wedge resection (LWR) for small gastric gastrointestinal stromal tumors (GIST) is now widely accepted, but its application for large GISTs remains controversial. This study aims to evaluate the feasibility and safety of LWR for suspected large (≥5 cm) gastric GISTs. METHODS: Retrospective review of 82 consecutive patients who underwent attempted LWR for suspected gastric GIST. LWR for large (≥5 cm) (n = 23) tumors was compared with LWR for small (<5 cm) tumors (n = 59)...

A 76-year-old woman with tarry stool was referred to our hospital for further examination. Contrast-enhanced computed tomography(CT)revealed a heterogeneous 15 cm tumor located in the left upper abdominal cavity. The tumor had a rich vascularity and was associated with intra-abdominal bleeding. Gastroscopy showed a large submucosal tumor in the gastric body. A biopsy was performed, and the patient was diagnosed with a c-kit-positive gastrointestinal stromal tumor(GIST)of the stomach. Imatinib mesylate(400mg/day)was administered for 6 months...

BACKGROUND: Dieulafoy lesion is a rare but serious cause of gastrointestinal hemorrhage. However, some cases can be occasionally found without bleeding during the endoscopic screening, and the management remains unclear. The aim of this article was to report the efficacy and safety of endoscopic submucosal dissection (ESD) for silent gastric Dieulafoy lesions, which presented as protrusion lesions mimicking gastrointestinal stromal tumors (GISTs). METHODS: Data from the patients with gastric protrusion lesions who underwent ESD from September 2008 to April 2016 in General Hospital, Tianjin Medical University, China were recorded...

Obscure gastrointestinal bleeding accounts for approximately 5-10% of patients presenting with gastrointestinal haemorrhage. The majority of lesions responsible were found to be located in the small bowel. Currently, capsule en-doscopy is the first-line tool to investigate the small bowel as it is a non-invasive, feasible and simple procedure. Howe-ver, capsule endoscopy sometimes identifies the source of bleeding outside the small bowel and within the reach of conventional endoscopy. We present the case of a 46 year-old man with few prior negative endoscopic procedures and iron-deficiency anaemia due to gastric GIST...

BACKGROUND: Recently, gastrointestinal stromal tumors that have developed outside of the digestive tract have been reported. These tumors are collectively termed extra-gastrointestinal stromal tumors. Extra-gastrointestinal stromal tumors can also develop in the liver. Only eight case reports involving primary GIST of the liver have been published. We report a case and review the literature regarding this disease. CASE PRESENTATION: A 70-year-old woman with a past history of gastric cancer visited our hospital for regular inspection...

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...

Compared to gastric gastrointestinal stromal tumor (GIST), hepatic GIST is very rare in clinic. Reports on clinicopathological feature and prognosis of this rare disease are limited in literature. The purpose of this study was, therefore, to summarize clinical and pathological features as well as prognosis of the primary hepatic GIST. One case of primary hepatic GIST from our center and 22 cases reported in MEDLINE or China National Knowledge Infrastructure (CNKI) were enrolled into this study. Clinicopathological features as well as survival data of hepatic GIST were analyzed and compared with 297 gastric GISTs and 59 small intestinal GISTs from our center...

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...
