Reasons for Diagnostic Failure in Forty-Five Consecutive Mucosal Cutting Biopsy Examinations of Gastric Subepithelial Tumors.
Conclusions: Clear exposure of gastric SETs during MCB may improve the diagnostic rate of such examinations. PMID: 32053861 [PubMed - as supplied by publisher]
Authors: Lee MW, Kim GH Abstract Gastric mesenchymal tumors (GMTs) are incidentally discovered in national gastric screening programs in Korea. Endoscopic ultrasonography (EUS) is the most useful diagnostic modality for evaluating GMTs. The differentiation of gastrointestinal stromal tumors from benign mesenchymal tumors, such as schwannomas or leiomyomas, is important to ensure appropriate clinical management. However, this is difficult and operator dependent because of the subjective interpretation of EUS images. Digital image analysis computes the distribution and spatial variation of pixels using texture analys...
Gastrointestinal submucosal tumor (SMT) shown as a hypoechoic mass lesion in endoscopic ultrasonography (EUS) mainly includes gastrointestinal stromal tumor (GIST), leiomyoma and schwannoma, and it is difficult to distinguish them by using imaging modalities. Although EUS-guided fine-needle aspiration is a standard option to diagnose SMTs, that is more or less invasive and sometimes less satisfactory due to insufficient amount of obtained tissue. Therefore, a new non-invasive and more reliable diagnostic method is still desired.
ConclusionsER is effective and safe for patients with GS with favorable long-term outcomes.
Conclusions: RLSD precisely locates gastric benign tumors during laparoscopic-endoscopic rendezvous procedures.
Conclusions: : APCT showed a lower overall accuracy than EUS; however, APCT remains a useful modality for malignant/potentially malignant gastric SETs. PMID: 31311912 [PubMed - as supplied by publisher]
Esophageal submucosal tumors (SMTs) are tissue protuberances covered with normal mucosa, usually without clinical symptoms. In esophagus, leiomyomas and gastrointestinal stromal tumors (GISTs) are two common SMTs and originate from the muscularis propria (MP) layer. The most are benign, but 10.8% leiomyomas might turn into leiomyosarcomas. GISTs are reported to be potentially malignant, especially with the large size or irregular boundary. Submucosal tunneling endoscopic resection (STER) and endoscopic submucosal excavation (ESE) are recently introduced to remove submucosal tumors (SMTs) originating from the muscularis propria (MP) layer.
Conclusions EUS-nCLE was feasible and safe to accurately diagnose gastric SETs. [...] © Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals: Table of contents | Abstract | Full text
CONCLUSIONS: EFR is effective and safe for patients with gastric gastrointestinal stromal tumors originated from muscularis propria layer and has the advantage of less invasive treatment and higher tumor resection rate. It should be considered for further application.RESUMO OBJETIVO: Este estudo revisou retrospectivamente 46 casos de tumores g ástricos estromáticos gastrointestinais tratados por microcirurgia endoluminal endoscópica de ressecção completa (EFR) em nosso centro de endoscopia gastrointestinal. Pretendemos avaliar a EFR para o tratamento de tumores gastrointestinais estrom&aa...
We report a case of duodenal schwannoma found incidentally during a health check-up endoscopy. On endoscopic ultrasonography, this tumor was suspected as a gastrointestinal stromal tumor; therefore, the patient underwent laparoscopic wedge resection of the tumor. Histopathology and immunohistochemistry confirmed that the duodenal lesion was a benign schwannoma. PMID: 29764009 [PubMed - as supplied by publisher]
Conclusion Laparoscopic-endoscopic cooperative surgery can be an effective minimally invasive approach to resect some lesions. This is first report of the patient with a synchronous gastric leiomyoma and an intramuscular granular cell tumor in the abdominal wall.
