endoscopic laparoscopic gastric gastrointestinal stromal tumor

AIMS: To evaluate the effectiveness and safety of endoscopic resection for gastric gastrointestinal stromal tumors (GISTs). MATERIAL AND METHODS: The effectiveness and safety of endoscopic resection were mainly assessed by complete resection rate, postoperative adverse event rate, and recurrence rate. Moreover, a comparison of endoscopic with laparoscopic resection for gastric GISTs was made through weighted mean difference by STATA 12.0 with regard to operation time, blood loss, and length of stay after including patients who underwent endoscopic or laparoscopic resection for gastric GISTs in the comparative studies...

BACKGROUND: Laparoscopic wedge resection of the stomach is an ideal procedure if the gastric gastrointestinal stromal tumors (GISTs) are located in the extraluminal stomach. When the tumor is located in the intraluminal stomach, two minimally invasive surgical procedures involving laparoscopic and endoscopic cooperative surgery (LECS) or endoscopic intragastric surgery (EIGS) are frequently performed. To date, there have been no comparative studies of LECS and EIGS in patients with intraluminal gastric GISTs regarding short-term and long-term outcomes...

BACKGROUND: Gastrointestinal stromal tumors (GIST) comprise about 80% of gastrointestinal sarcomas. In patients with localized disease, surgery is considered as "Gold Standard" treatment. Organ-sparing radical en-block resection is widely accepted practice. Since lymph node dissection is not routinely indicated, minimally invasive approach is of particular interest. The aim of this study is to investigate the short-term outcomes of different surgical treatment of GISTs. METHODS: We analyzed data of 116 patients who received surgical treatment for localized forms of GIST...

AIM: Gastrointestinal stromal tumors (GIST) are quite rare tumors, but yet they are the most common mesenchymal lesions of gastrointestinal tract. Their outmost frequent origin site is stomach and presently surgical resection is the mainstay in the treatment of gastric non metastatic GIST. Their peculiar characteristic of growth and poor metastatic tendency make this tumors particularly prone to be managed by minimally invasive technique. Presenting our experience we want show the feasibility and safeness of laparoscopic approach for gastric GIST and its benefits versus traditional open surgery and pointing out short term and long terms outcomes...

AIM: The goal of this work was to present our experiences and results of treatment of gastric tumors using the per oral specimen extraction (POSE) technique. MATERIAL AND METHODS: A retrospective analysis a group of patients treated with laparoscopic stomach wedge resection of gastrointestinal stromal tumor (GIST). During that time 50 patients underwent laparoscopy due to the suspicion of GIST. In 12 patients resected material was removed endoscopically per os (POSE)...

Background and study aims We have developed a combined laparoscopic and luminal endoscopic surgery technique for resection of gastric submucosal tumors (SMTs) that can be performed without excessive resection of the stomach. In a multicenter retrospective study we aimed to evaluate the feasibility and safety of laparoscopic and endoscopic cooperative surgery (LECS) for gastric SMT resection. Patients and methods Between October 2007 and December 2011, 126 patients with gastric SMTs underwent LECS at 8 institutions...

BACKGROUND: Endoscopic full-thickness resection (EFTR) is a minimally invasive method for en bloc resection of gastrointestinal (GI) lesions originating from the muscularis propria layer. Successful closure of the wall defect is a critical step. OBJECTIVE: The aim of this study was to evaluate the feasibility and efficacy of a novel and simplified endoscopic grasp-and-loop (GAL) closure method using an endo-loop assisted with grasping forceps for defect closure...

BACKGROUND & AIMS: Laparoscopic resection (LAP) and endoscopic submucosal dissection (ESD) of small gastrointestinal stromal tumors (GISTs) has been reported by large amount of literature. However, the management of small GISTs remains controversial. This study evaluated the efficacy of ESD and LAP for small gastric GISTs and provided long-term outcomes of the two methods. METHODS: A total of 126 patients who underwent ESD or LAP for small gastric GISTs between 2009 and 2016 were retrospectively collected from medical records in our hospital and we made telephone follow-up about recurrence rate...

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)...

OBJECTIVE: To retrospectively analyze the clinicopathology of patients with gastric gastrointestinal stromal tumor(gGIST) who underwent radical excision within 18 years in 10 domestic medical centers in order to understand the status of domestic surgical treatment of gGIST. METHODS: Clinicopathological data of gGIST patients undergoing radical excision in 10 medical centers from January 1998 to January 2016 were collected, and their operational conditions, postoperative adjuvant therapy, gene detection and survival were analyzed retrospectively...

Despite endoscopic resection has been performed to treat gastric gastrointestinal stromal tumor (GISTs). However, the safety and long-term outcomes remains controversial. This study aims to compare the safety and surgical outcomes of endoscopic versus laparoscopic resection of gastric GISTs. A total of 335 patients that were pathologically confirmed with gastric GISTs (tumor size ≤ 3.5 cm) were surgically treated with endoscopic resection (endoscopic group) or laparoscopic resection (laparoscopic group) in three institutions from March 1, 2011 to October 1 2014...

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...

AIM: to evaluate objectively the effectiveness of currently used diagnostic and curative approaches to gastrointestinal stromal tumors (GIST). MATERIAL AND METHODS: Early and remote results of treatment of 49 patients with gastric GISTs were presented. Herewith in 20 (40.8%) patients the disease was complicated by gastrointestinal bleeding. 43 (87.7%) of 49 patients with gastric GIST were operated. Conventional surgery was performed in 24 (55.8%) cases, laparoscopic interventions - in 12 (28%) cases, endoscopic endoluminal - in 7 (16...

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...

The present study reports a novel approach to laparoscopic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumor (GIST) resection and cholecystectomy, and conducts a review of the associated literature. The novel surgical procedure was performed on one patient who was diagnosed with a GIST and cholecystic polypus. The GIST was resected using an insulation-tipped diathermic electrosurgical knife under the guide of an endoscope. Subsequently, a cholecystectomy was performed by inserting two more 5-mm trocars and instruments transumbilically, guided using an endoscope...

A 44-year-old man consulted an internist because of abnormalities in an upper gastrointestinal series. It showed an elevated lesion with central depression in the greater curvature of the middle part of the stomach. Upper gastrointestinal endoscopy showed an elevated lesion with central depression, bridging hold, and no abnormalities of the gastric mucosa in the greater curvature of the middle part of the stomach. Endoscopic ultrasonography showed a submucosal tumor derived from the muscle layer of the stomach...

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...

Herein, we report a case of a gastrointestinal stromal tumor (GIST) at the esophagogastric junction (EGJ) that was successfully treated by a laparoscopic wedge resection (LWR) after dissection of the seromuscular layer around the tumor to prevent postoperative deformities and stenosis of the EGJ. Subsequently, the abdominal esophagus was wrapped by the gastric fornix according to Dor's method in order to prevent reflux esophagitis after surgery.A 71-year-old female patient was admitted with a diagnosis of a GIST (23 × 20 × 20 mm) at the EGJ...
