Full-thickness endoscopic resection of nonintracavitary gastric stromal tumors: a novel approach

Abstract

Endoscopic resection is safe and effective for treating nonintracavitary stromal tumors. The endoscopic natural-cavity technique produced less surgical injury to the patients and preserved the anatomy of intra-abdominal structures. In addition, the endoscopic technique reduced operative times, postoperative bleeding, and costs.

Endoscopic Full-Thickness Resection of Submucosal Gastric Tumors

“…The median procedure time was 15 min (IQR [11][12][13][14][15][16][17][18][19][20][21][22]. Full-thickness resections produced complete gastric wall defects in 3/6 (50%) cases.…”

“…For this reason, surgery, nowadays often in the form of laparoscopic surgery, is still considered to be mainstay of therapy for GISTs [3,[8][9][10][11]. For small, asymptomatic gastric SMTs [3,6,12], there is, however, no consensus on how to treat them [13][14][15]. Most clinical studies attempting endoscopic resection include laparoscopic assistance [14,[16][17][18].…”

“…For small, asymptomatic gastric SMTs [3,6,12], there is, however, no consensus on how to treat them [13][14][15]. Most clinical studies attempting endoscopic resection include laparoscopic assistance [14,[16][17][18]. If pure endoscopic resection is to play a role in this setting, endoscopic full-thickness resection (EFTR) with reliable defect closure is the aim which should be strived for.…”

Endoscopic diagnosis and treatment of gastric glomus tumors

“…However, endoscopic resection can be performed to preserve gastric function as much as possible. 15,16 Because of the success of ESD for en bloc resection of early gastric cancer, 17 studies have begun to find the benefits of endoscopic resection for submucosal tumors. 18,19 At our institute, endoscopic submucosal enucleation in this study was performed to remove many gastric submucosal tumors.…”

Clinical significance of lymphadenectomy in patients with gastric cancer

“…Miyashiro et al [95] demonstrated that an extensive surgical experience is necessary for application of SNB concept and standardization of SLN mapping technique, using improved tracer, and guideline to evaluate the positiveness of SLN specimen should be planned to incorporate SNB in routine practice [96] . Recent studies and the latest metaanalysis of SLN mapping have shown a high detection rate (93.7%) and an accuracy of 92% [97] and suggest that the SNB concept could be suitable for tumors following endoscopic resection [98] and could represent a new era of sentinel node navigation surgery in EGC [99,100] . Moreover, its success rate did not correlate to tumor grade [101] .…”
