ABSTRACT
Objective To explore the feasibility of three-dimensional (3D) laparoscopic technique in treating Hirschsprung's disease in infants. Methods 13 cases of Hirschsprung's infants diagnosed by lower gastrointestinal radiography and rectal mucosa biopsy in the third affiliated hospital of zhengzhou university during the period from July 2015 to March 2017 were collected. All of them were treated by laparoscopic 3D technique. Results The 13 case of surgeries were all accomplished successfully, and no case was transferred to laparotomy. After operation, the symptom of abdominal distention disappeared, no difficult defecation, no anastomotic fistula. And routine anal dilatation 2 weeks after operation of anal. Follow-up for 6 to 24 months, there was no abdominal distension, fecal incontinence, anal stenosis and other complications. Conclusions 3D laparoscopic technique has the advantages of high resolution and three-dimensional, which is safe and feasible for the treatment of infant's Hirschprung's disease.
ABSTRACT
Objective To analyze the effect of partial nephrectomy with three-dimensional laparoscopy for the treatment of renal tumor.Methods From October 2013 to September 2015, 11 patients underwent 3D laparoscopic partial nephrectomy for renal tumor in our hospital.All the cases were given retroperitoneal approach.The renal artery was seperated and blocked, and the renal tumor was exposed and completely resected around the edge.The wound was double layer sutured with Vicryl.Results All the 11 operations were finished smoothly without conversion to open surgery.The operative time was 70-180 min (mean, 100 min), the ischemic time was 14-35 min (mean, 25 min), and the estimated blood loss was 50-300 ml (mean, 90 ml).There were 1 case of intraoperative peritoneal perforation, 2 cases of subcutaneous emphysema, and 1 case of perirenal hematoma.No other operative or postoperative complications occurred.The post-operative hospital stay was 5-10 d (mean, 6 d).Post-operative follow-ups for 3-14 months (mean, 10 months) in 10 cases found no recurrence or metastasis or renal dysfunction.Conclusions Partial nephrectomy of renal tumor with three-dimensional laparoscopy is safe and feasible.The outcome is satisfying and worthy of application.
ABSTRACT
Objective This paper preliminarily research the clinical effect of 3D laparoscopy in the biliary tract surgery.Methods Thirty-eight patients clinical data of cholelithiasis who accepted laparoscopic cholecystectomy and laparoscopic choledocholithotomy T-tube drainage from January 2015 to June 2016 were retrospectively analyzed,which sixteen patients underwent three-dimensional laparoscopic surgery while twenty-two patients underwent two-dimensional laparoscopic surgery. The operation time, intraoperative blood loss, postoperative drainage,time of drainage, postoperative hospital stay, hospital costs and the incidence of complications were observed in two groups.Results There was a statistical significant (P 0.05) in postoperative drainage, time of drainage, postoperative hospital stay, hospital costs and the incidence of complications between the two groups. One patient of 2D group suffered residual stones and recovered by choledochoscopy through T tube sinus after two months, while no one suffered residual stones in 3D group. There was no recurrence of stones in both groups during the follow-up period which varied from two months to eighteen months.Conclusions 3D laparoscopy enables biliary tract surgery was more accurate and minimally invasive, it has a widely applicable prospect.
