Objective To explore the clinical effect of endoscopic sclerosing agent and tissue glue injection combined with ligation in the treatment of rectal ectopic varices(EV)bleeding.Method A retrospective analysis was conducted on 60 patients with rectal EV bleeding who received endoscopic treatment from January 2017 to January 2022.According to the surgical method,the patients were divided into two groups,with 30 cases in the control group receiving endoscopic ligation treatment;30 cases in the observation group were treated with endoscopic scleroing agent and tissue glue injection combined with ligation.Follow up was conducted according to a cycle of 1,3,6 and 12 months after surgery,and the following indicators were compared between the two groups of patients:successful surgical hemostasis rate,incidence of postoperative complications,mortality rate,improvement of postoperative varicose vein diameter,and postoperative response rate.Result The success rate of surgical hemostasis in the observation group was 93.3%,significantly higher than 66.7%in the control group,the incidence of abdominal pain and fever in the observation group was 10.0%and 10.0%,respectively,significantly lower than 33.3%and 36.7%in the control group,there were 2 deaths in the observation group and 9 deaths in the control group,the mortality rate in the observation group was 6.7%,significantly lower than the 30.0%in the control group,the preoperative venous diameter of the observation group was(1.60±0.36)cm,and the postoperative diameter continued to decrease,at the 12th month after surgery,the diameter was(0.78±0.31)cm,while in the control group,the preoperative venous diameter was(1.52±0.26)cm,the postoperative diameter continued to increase,and at the 12th month after surgery,the diameter was(1.55±0.36)cm,the postoperative effective rate of the observation group was significantly better than that of the control group,the differences were statistically significant(P<0.05).Conclusion The combination of endoscopic scleroing agent and tissue glue injection combined with ligation for the treatment of rectal EV bleeding has a higher success rate and effective rate of surgical hemostasis,fewer postoperative complications,lower mortality rate during follow-up observation,and satisfactory clinical efficacy.It is worth further promoting and applying in clinical practice.

Objective:To investigate the clinical characteristics, differential diagnosis, treatments and prognosis of facial nerve hemangioma and schwannoma at genicular ganglion, so as to provide reference for clinical diagnosis and treatments of facial nerve tumor at genicular ganglion.Methods:Clinical data of 13 patients with facial nerve tumors at genicular ganglion confirmed by postoperative pathology in the Ninth People′s Hospital affiliated to Shanghai Jiaotong University School of Medicine from March 2018 to April 2020 were retrospectively analyzed, including seven cases of hemangioma and six cases of schwannoma. There were eight males and five females. Their ages ranged from 20 to 65, with an average age of 40. The course of disease ranged from 3 to 118 months, with an average of 52 months. All the patients underwent preoperative HRCT of the temporal bone and facial nerve dynamic contrast-enhanced(DCE) MRI examinations. All the patients had detailed surgical procedures and at least one-year postoperative follow-up.Results:On HRCT of the temporal bone, (4/7) hemangioma at geniculate ganglion showed characteristic honeycomb appearance, while 6/6 schwannoma and 3/7 hemangiomas showed expansive bone changes. On DCE-MRI, geniculate ganglion hemangioma (7/7) showed characteristic "point-to-surface" enhancement, and schwannoma (6/6) showed characteristic "face-to-surface" enhancement. For five hemangioma-patients with HB-Ⅱ-Ⅳ before surgery, the facial nerve anatomy was completely preserved through transcanal endoscopic approach(TEA), and the facial nerve function improved one year after surgery (two cases of HB-I, two cases of HB-Ⅱ, and one case of HB-Ⅲ). For two patients, with preoperative facial nerve function HB-Ⅴ-Ⅵ, since their tumors was inseparable from the nerves, they were performed with facial nerve anastomosis during the surgery, and the facial nerve function was improved to HB-Ⅳ level one year after surgery. For six patients with meningioma whose facial nerve function was greater than or equal to HB-Ⅲ, based on the preoperative hearing level, the involved segments, and duration of facial paralysis, three of them were conducted surgeries through middle cranial fossa approach, one by translabyrinthine approach, and one via mastoid approach. Two patients among them with complete facial paralysis over three years preoperatively were not performed facial nerve anastomosis after total resections of the tumors, and there was no improvement in facial nerve function one year after surgery. Three patients underwent facial nerve anastomosis after total tumor resections, and their facial nerve function was HB-Ⅲ in one patient, HB-Ⅳ in two patients one year after surgery. One patient (preoperative HB-Ⅲ) had a normal hearing level preoperatively, and the tumor involved the labyrinth segment. To protect the hearing, partial tumor was resected through the middle cranial fossa approach, and facial nerve function improved to HB-Ⅱ one year after surgery.Conclusions:Temporal bone HRCT combined with DCE-MRI are useful for the differential diagnosis of hemangioma and schwannoma at geniculate ganglion and provide references for preoperative clinical decision makings. It is extremely necessary to select the appropriate surgical approach based on the patient′s hearing and involved segments. For geniculate ganglion hemangioma, early surgery can improve the possibilities of anatomical integrity of facial nerve, thereby improving facial nerve function postoperatively.TEA is a kind of surgical method worth consideration, with the characteristics of minimally invasive, favorable postoperative features, and so on. For schwannoma, one-stage functional reconstruction of the facial nerve is recommended during the resection of the tumors because of the inevitable damage to the anatomical integrity of the facial nerve.
