Objective To explore the long-term outcomes of endoscopic submucosal dissection (ESD) of gastric GISTs.Methods Data of 25 patients with gastric stromal tumors,who underwent ESD,were reviewed in terms of clinical characteristics,histopathologic results,complications and long-term outcomes.Results Twenty-five patients underwent one-time complete removal of lesion, with a average tumor size of 3.0 cm (range,0.6 to 7.6 cm).The average time of operation was 65 minutes (range,15 to 154 minutes).one case was observed with intraoperative hemor-rhage of 200 mL blood,which was successfully managed by hemostatic forceps.Perforation with incidence rate of 16%occurred in 4 cases and was closed well with clips.Mucosal mechanical laceration of esophagus occurred in 1 case when the big tumor was taken out.The average length of hospi-talization was 7.3 days (range,4 to 21 days).A follow-up for 30 months (range,13 to 54 months) showed no tumor recurrence or metastasis. Conclusion ESD is an effective and safe endoscopic procedure to remove gastric GISTs for long-term outcomes in patients with no metastasis.

Objective To investigate the serum levels of semaphorin 3E(Sema3E)in patients with intracranial aneurysms,revealing the correlation between Sema3E and 1-month poor prognosis after interventional embolization.Methods This study was a prospective single-center cohort study,recruiting 102 consecutive patients with intracranial aneurysms who underwent interventional surgery from June 2020 to January 2022 in our hospital.Among them,11 patients were excluded.Clinical and radiological profiles were collected.Peripheral blood was collected after admission,and serum Sema3E levels were determined by enzyme-linked immunosorbent assay.All the aneurysms were treated with endovascular coil embolization or stent-assisted coil embolization.The primary outcome was evaluated with the Glasgow Outcome Scale(GOS)1 month after interventional therapy.The favorable outcome was defined as a GOS score of 4-5,and a poor outcome was defined as a GOS score of 1-3(severe disability,vegetative state,or death).Univariate and multivariate logistic regression analyses were used to identify potential prognostic factors after interventional therapy.Results The average age of 91 patients with intracranial aneurysm was 59.9±11.0 years old,including 70 cases(76.9%)with favorable prognosis and 21 cases(23.1%)with poor prognosis.The mean preoperative Glasgow Coma Scale(GCS)score of the poor prognosis group(9.4±4.5)was significantly lower than that of the favorable prognosis group(13.3±2.5;P<0.001).In the poor prognosis group,the Hunt-Hess grade(3.6±0.6 vs.2.0±1.3,P<0.001)and the serum Sema3E levels[(6.21±1.58)μg/L vs.(4.38±1.77)μg/L,P<0.001]were significantly higher than those in the favorable prognosis group.Logistic regression analysis showed the Hunt-Hess grade(OR =7.150,P =0.003),stent-assisted coil embolization(OR =15.777,P =0.010),and the serum Sema3E level(OR =1.756,P =0.027)were independent prognostic factors for intracranial aneurysms after interventional therapy.Conclusions The serum Sema3E level is closely correlated with the severity of intracranial aneurysms.The serum Sema3E level is a prognostic factor for interventional treatment,which can be used as a biomarker for predicting poor outcomes.
