ABSTRACT
Objective To investigate the place reaction of support drainage tube in cholecystojejunostomy and its pathological changes.Methods Eight pigs were randomized into 2 groups.The tube-placing cholecystojeunostomy(n=2)or choledochocholedochostomy(n=2)and non-tube-placing cholecystojejunostomy(n=2)or choledochocholedochostomy(n=2)were performed respectively.All the 8 pigs were sarcrificed 3 months after the operation for pathological examination.Results Gross anatomy catheter group showed anastomotic inflammatory hyperplasia, wall hardening hyperplasia,luminal narrow contracture and stone formation.Microscopic biopsy showed bile duct mucosa in interstitial lymphocytes, plasma cells and other chronic inflammatory cell infiltration, a large number of fibrous tissue hyperplasia.However, these features were not found in pigs without placing the tube.Conclusion The tube can not prevent the stenosis.It might promote the formation of stricture since it can stimulate inflammatory hyperplasia and tissue hardening.
ABSTRACT
Objective To investigate the feasibility of cholangioenterostomy without stent tube drainage. (Methods) In this study 52 cases anastomosed without stent tube drainage (group A) and 56 cases with stent tube drainage (control,group B) were included. The patients′course of therapy and recovery, postoperative follow-up and reoperation were compared between group A and B. Results The rate of bile leakage was (5.8)% (3/52) in group A and 3.6%(2/56) in group B, respectively ,which was not significant(P
ABSTRACT
Objective To evaluate the clinical application of vaginal hysterectomy. Methods Clinical data of 118 patients with benign uterine diseases treated by vaginal hysterectomy (Vaginal Group) were retrospectively reviewed and were compared with those of 124 patients who underwent open hysterectomy (Open Group). Results The operative time (50 1 min?15 3 min), the intraoperative blood loss (150 4 ml?56 ml), the number of patients with a need for postoperative analgesics (26 cases), the postoperative pyrexia (42 cases), the time to first getting out of bed (26 4 h?6 3 h) and the length of hospitalization (5 2 d?1 2 d) in the Vaginal Group were significantly less than those in the Open Group (70 3 min?12 4 min, 212 2 ml?70 3 ml, 124 cases, 94 cases, 48 5 h?12 1 h, 8 2 d?2 2 d, respectively; P =0 000). There were no statistical significances between the two groups in occurrence of intra- or post- operative complications (Vaginal Group: 0 8%, 1/118, Open Group: 5 6%, 7/124; ? 2=2 982, P =0 084). Conclusions Vaginal hysterectomy has the advantages over open hysterectomy in minimal invasion and rapid recovery.
