Objective:To explore the application value of uterine net-like compression suture in postpartum hemorrhage(PPH).Methods:The data of 84 refractory PPH patients from six hospitals specialized in children and women in Chengdu from January 2015 to March 2023 were retrospectively analyzed.They were divided into two groups according to the surgical methods:41 cases of B-Lynch suture(control group)and 43 cases of uterine net-like compression suture(observation group).The clinical efficacy of the two methods was observed,and the perioperative indicators and clinical outcomes were compared between the two groups.Results:①31 cases in the control group and 42 cases in the observation group,were successfully hemostatic and retained the uterus,with effective rates of 75.61%and 97.67%,respectively.The difference was statistically significant(P＜0.01).②There were no significant differences in the rates of all preoperative diagnosis and preoperative blood loss between the two groups(P＞0.05);in the observation group,the intraoperative and 2 h postoperative blood loss,the units of postoperative blood transfusion,the incidence rate of requiring postoperative intensive care and the hospitalization days,were less than those in the control group(P＜0.01).③During a follow-up period of 10-48 months,all 73 pa-tients without hysterectomy recovered menstrual cycles within 12 months after the surgery.Thirteen cases experi-enced reduced menstrual flow with cycle changes in the control group(41.94%),while 6 cases experienced in the observation group(14.29%),and the difference was statistically significant(P＜0.01);5 cases(16.13%)had sub-sequent pregnancy in the control group,while 12 cases(28.57%)had in the other,with no significant difference(P＞0.05).Conclusions:The two uterine sutures for refractory PPH have both achieved good clinical curative effects,and the uterine net-like compression suture shows therapeutic advantages on intraoperative and postoper-ative blood loss,postoperative blood transfusion,and hospitalization days.The uterine net-like compression suture has no special requirements for medical devices or materials,and thus has important popularization and applica-tion value for primary obstetrics with limited medical conditions.

Objective:To evaluate the effect of pedicled omentum packing of pelvic floor after laparoscopic Miles precedure in the prevention of short-term postoperative complications.Methods:Seventy-two patients undergoing laparoscopic combined abdominal perineal resection for rectal cancer at He'nan Tumor Hospital from Jan 2014 to Aug 2021 were retrospectively reviewed. The observation group underwent pelvic floor reconstruction with pedicled omentum, while in control group the pelvic floor was leaving unconstructed.Results:There was no intestinal obstruction in the observation group. There were 5 cases of intestinal obstruction in the control group. Three were recovered by conservative treatment, 2 cases underwent laparotomy and 1 case underwent anastomosis between small intestine and small intestine. The incidence of intestinal obstruction between 2 groups was statistically different (0 vs. 14%, χ2=5.083, P=0.024 ). The operation time, hospital stay between the two groups were statistically different [(195±13) min vs. (159±9) min, t=10.047, P=0.000; (11.9±0.9) d vs. (14.9±2.1) d, t=-5.996, P=0.000 ). Between the two groups, there were no significant differences in the incidence of presacral infection , pulmonary infection, venous thrombosis and intraoperative blood loss (all P>0.05) . Conclusion:Pedicled greater omentum used in pelvic floor reconstruction after laparoscopic Miles procedure reduces the incidence of short-term postoperative complications, especially of intestinal obstruction.

Objective To explore the MRI features of cavernous hemangioma in the thoracic spinal epidural space,to improve the recognition of the disease.Methods The clinical,pathological and MRI data of 7 cases with cavernous hemangioma in the thoracic spinal epidural space confirmed by surgery and pathology were analyzed retrospectively.Results 7 cases of cavernous hemangioma in the thoracic spinal epidural space were included in our study,all cases underwent MRI contrast enhancement examination and 6 of them underwent conventional MRI examination.On T1WI,4 cases showed hypointensity,2 cases showed slightly hypointensity and 1 case showed mixed slightly hypointensity.On T2WI,5 cases showed slightly hyperintensity,1 case showed slightly hypointensity. On fat suppression sequence,5 cases showed hyperintensity,1 case showed heterogeneous hyperintensity.On diffusion-weighted imaging (DWI),7 cases showed obviously hyperintensity.On contrast-enhanced images,the lesions enhanced homogeneously in 5,enhanced heterogeneously in 2.Conclusion MRI can display the location,appearance and enhancement pattern of thoracic spinal epidural cavernous hemangioma distinctly,while definite diagnosis of which still depends on pathology.
