The clinical study of comparison direct-vision and two stiches method in PPH surgery / 实用医学杂志

ABSTRACT

Objective To evaluate the effect of direct-vision and two stiches method and other techno logical improvements on PPH surgical operation by prospective randomized controlled study.Methods A total of 683 patients were randomly assigned.Direct-vision and two stiches method technological improvements were applied in observation group,while standard operation procedures were performed in control group.Operation time,blood loss during operation,specimen size,post-operative complication and other conditions were compared between observation group and control group.Results In 350 cases of the observation group,the average surgical time was (12.2 ± 4.0)minutes,blood loss during operation (4.95 ± 2.82)mL and specimens width (2.61 ± 0.32)cm.2 patients with hemorrhage were performed hemostasis after surgery.5 cases suffered from edema or thrombus in haemorrhoids zones after surgery.In 333 cases of the control group,the average surgical time was (17.2 ± 3.6)minutes,blood loss during operation (7.55 ± 3.94) mL and specimens width (1.18 ± 0.56) cm.5 patients were performed hemostasis after surgery,14 cases suffering from edema or thrombus in haemorrhoids zones after surgery,postoperative infection in 1 case,rectostenosis in 1 case,and 1 case in rectovaginal fistula.In the observation group,operation time was shorter than that in the control group.No significance was found in excision width and depth.The serious complications after surgery are fewer in observation group than that in the control group.Conclusion The direct-vision and two stiches method and other technological improvements are safe and effective,meanwhile operation difficulty can be reduced.
