Clinicopathological characteristics and prognosis of gastrointestinal vascular tumours.

To evaluate the clinicopathological characteristics and prognosis of gastrointestinal vascular tumours. By reviewing the information from the electronic medical record system and pathology database of Hangzhou First People's Hospital affiliated with Zhejiang University School of Medicine and Jiaxing First People's Hospital from June 2008 to December 2019, 31 patients pathologically diagnosed with vascular tumours were included in this study. The age of onset, sex differences, clinical manifestations, imaging and endoscopic characteristic manifestations, pathological characteristics, treatment methods and prognosis were analysed. The pathological classification was haemangiolymphangioma, haemangioma, and lymphangioma in 8, 14, and 9 cases, respectively. The age of onset was 44-66 years, with no significant difference according to sex (P = 0.583); 32.26% (10/31) of patients had no noticeable symptoms, 37.5% (12/31) of patients had gastrointestinal bleeding, and 6.45% (2/31) of patients, all with lymphangioma, had intestinal obstruction. The lesions were located in and below the duodenum. Endoscopy showed colour differences. Both endoscopic and surgical treatments were safe and effective. The mean survival time was 57.06 ± 35.64 months. Regarding vascular tumours without typical symptoms, the main pathological classification is haemangioma. Vascular tumours are often clinically identified because of bleeding or obstruction and can be treated with endoscopy or surgery. Clinical follow-up is recommended because no invasive manifestations or instances of recurrence were observed.

Diagnostic value of SpyGlass endoscopy system for indeterminate biliary stricture / 中华消化内镜杂志

Objective:To investigate the diagnostic value of SpyGlass endoscopy system (short for SpyGlass) for indeterminate bile duct stricture.Methods:Data of patients who underwent SpyGlass examination for indeterminate bile duct stricture at Hangzhou First People′s Hospital from September 2012 to August 2017 were reviewed. The diagnostic value of SpyGlass for indeterminate bile duct stricture was analyzed.Results:A total of 88 patients with indeterminate biliary stricture were diagnosed with SpyGlass. The procedure success rate was 97.7% (86/88). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of SpyGlass for indeterminate bile duct stricture were 98.1%(52/53), 96.9% (31/32), 97.6% (83/85), 98.1% (52/53)and 96.9% (31/32), respectively. Three patients (3.5%, 3/86) had postoperative complications and were cured by conservative treatment.Conclusion:SpyGlass is safe and effective for indeterminate biliary stricture with high sensitivity and accuracy and low incidence of complications.
