Objective To review the experience of the bone traction treatment for displaced fracture of femur shaft in children.Methods All of the cases were treated with femur supercondylar traction,and they were fixed in a stable position with hip joint in 90? flexion and 30?~45? abduction and with knee in 90? flexion.Result The effects of 86 cases were satisfactory.Conclution This method is simple and effective.It reduces complications of skin traction and operation to patients.

Purpose To evaluated the effect of ureteral stent placement before flexible ureteroscopic lithotripsy(FURL).Methods A systematic search of PubMed,Cochrane Library,Embase,Scopus,VIP,CNKI,Wanfang database from databases establishment to February 2017 was performed to identify all clinical trials on the effect of ureteral stenting before flexible ureteroscopic lithotripsy.The outcomes included stone-free rate,mean operative time,success rate of ureteral access sheath placement and postoperative complications.RevMan 5.3 software was used to complete the Meta statistical analysis.Results Three randomized and four non-randomized studies were analyzed,which consisted of 1 176 patients including 788 cases in experimental group,388 cases in control group.Meta-analysis showed significant differences between experimental group and control group in stone-free rate (OR =1.88,95％ CI 1.30-2.71,P ＜ 0.001).There was no statistically significant difference in mean operative time between experimental group and control group (WMD =-0.99,95 ％ CI-10.63-8.65,P =0.84).The success rate of ureteral access sheath placement was significantly higher in experimental group than that in the control group (OR =8.24,95％ CI 3.17-21.45,P ＜ 0.001).In term of postoperative complications,two groups had significant differences (OR =0.57,95 ％ CI 0.33-0.99,P =0.04).Conclusions Preoperative ureteral stenting can increase the stone-free rate and the success rate of ureteral access sheath placement,and reduce complications of FURL.There is no statistically significant difference in mean operative time.

Objective:To investigate the feasibility of oblique overlap anastomosis plus single flap valvuloplasty (OSF) for reconstruction after laparoscopic proximal gastrectomy.Methods:The C-shaped seromuscular flap (2.5 × 3.5 cm), which was 2 cm from the top of the remnant stomach, was extracorporeally created on the anterior wall of the remnant stomach. The stomach was opened approximately 1.0 cm above the lower edge of the mucosal flap. Four supporting stitches were sutured around the hole and the right wall of the esophageal stump was incised with a support suture to prevent the linear stapler from entering the submucosa. Liner stapler was inclined to the left side of the esophagus at an angle of about 30 degrees to the longitudinal axis of the esophagus for oblique anastomosis between the dorsal side of the esophagus and the anterior stomach and then esophagogastrostomy was performed with the length of anastomosis was 4 cm. Entry hole was suture with 3 stitches and then the linear stapler was used for closing the entry hole. Finally, the seromuscular flap was closed using barbed sutures.Results:Clinical data of 11 patients with Siewert type II esophagogastric junction adenocarcinoma who underwent radical gastrectomy and reconstruction by OSF between January 2022 and May 2023 were retrospectively collected. There were 7 males and 4 females. The average age was (69.9±7.8) years, the BMI was (21.7±7.2) kg/m 2 and the tumor size was (2.1±0.6) cm. OSF reconstruction was successfully completed in all 11 patients. The median operative time was 275 (270-428) minutes, the time for OSF reconstruction was 112 (80-140) minutes, and the blood loss was 50 (20-400) ml. The pathological stage was 0-I in 7 cases and II-III in 4 cases. The patients were fed on the 4th day (4-7 days) and discharged from hospital on the 7th day (6-9 days) after surgery. No patient had gastroesophageal reflux symptoms of grade B and above, and no patient took anti-reflux medicine. Conclusions:OSF is a safe and feasible treatment for Siewert type II esophagogastric junction adenocarcinoma.

Objective:There is no standard method for esophageal remnant gastric reconstruction for proximal gastrectomy. Reflux esophagitis caused by esophagogastrostomy remains a difficult surgical problem. To report the preliminary surgical results of novel esophagus-conical remnant gastric side overlap anastomosis (CGEO) , with particular emphasis on postoperative esophageal reflux.Methods:In June 2022, we developed a novel CGEO for laparoscopic proximal gastrectomy on two patients with Siewert type II esophagogastric junction adenocarcinoma. Surgical procedures for CGEO: (1) Laparoscopic proximal gastrectomy and preparation of conically shaped gastric remnant; (2) Determining anastomotic site of residual stomach and esophagus; (3) Side-to-side anastomosis of right esophageal wall to anterior of conical gastric remnant; (4) Valvuloplasty of esophageal stump.Results:Case 1 was a 71-year-old man with an operation time of 305 minutes and was successfully discharged from the hospital on the 9th day after surgery, and the postoperative pathology was T3N0M0. Case 2 was an 82-year-old man with an operation time of 325 minutes. He was discharged on the 10th day after surgery. In both cases, only mild esophageal mucosal changes were seen in gastroscopy, there were no obvious symptoms of esophageal reflux. There was also no significant weight change at half a year after operation.Conclusion:CGEO is moderately safe in radical surgery for proximal gastric cancer, and may have a preventive effect on the occurrence of postoperative esophageal reflux, but long-term results need to be confirmed by further studies with follow-up.
