Objective To compare and assess the effectiveness between total vaginal hysterectomy (TVH), Laproscopical hysterectomy (LH) and minilaporotomy hysterectomy (MiniLPT). Methods We searched CBM, CKNJ, MEDLINE, EMbase, Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED to screen randomized controlled trials (RCTs) comparing one surgical approach to another of extrafascial hysterectomy (between TVH, LH and miniLPT) which were done to those women with benign gynecological diseases. As to economy assessment, studies of cost-effective analysis were also included. Those observational studies reporting rare or important long-term outcome were also included. The quality of the included studies was evaluated by GRADE (Grades of Recommendation, Assessment, Development and Evaluation) system and principle of Cochrane Reviewer Handbook 4.2.3 RCT. Results Finally, we identified 12 trials including 10 RCTs, 1 retrospective cohort study and 1 respective cohort study. Cost-effective analy- sis showed when in indication of VH, TVH was more cost-effective than LH. When TVH was less but still accessible, metaanalysis showed TVH had significant advantages than the other two approaches in many sides. Compared with LH arm, operation time was shorter at a WMD 47.2 min and 95%CI 32.2 to 62.3 min, blood loss was less at a WMD 158.7 ml and 95%CI – 190.9 to – 126.4 ml, hospital stay was shorter at a WMD 23.9 h and 95%CI – 25.4 to – 13.9 h, and the first stool or to break wind was quicker at a WMD – 8.1 h and 95%CI – 10.8 to – 5.3 h in TVH arm. But on the other side, the incidence rates of bad wound healing (such as vaginal cuff infection, abdominal wall infection, wound dehiscence, etc.), of secondary infection (such as UTI, URI, unknown infection, etc.), and of febrility were less common in LH arm than those in TVH arm with no significant difference. Meanwhile, ratio of sexual hypofunction, declined marital life quality and worse body image were more in TVH arm than those in LH arm, implying LH arm provided a better post-operation sexual life recovery. Operation time was longest in miniLPT arm at a WMD 37.0 h and 95%CI 13.5 to 60.5 h and blood loss was most at a WMD 208.5 ml and 95%CI 141.4 to 375.7 ml, too. The febrility rate was also the most common in miniLPT arm at a Peto OR 3.8 and 95% CI 1.1 to 12.6. The differences were significant. Conclusion TVH is the least invasive approach and better in cost-effectiveness when accessible. However, when inaccessible, the limitations remain unclear, depending on surgeons’ own techniques and experience as well as patients’ individual conditions. LH does better in improving quality of life and body image. Cost-effectiveness of LH may become much better by reducing blood loss during operation through improving techniques or instruments of hemostasis. Limited application of non-reproducible instrument or cost and promotion of their recycle may help a lot in bringing down LH operation cost, too. Owing to limited studies, the advantage of miniLPT should be evaluated more precisely by its technical development and more penetrating researches. There are huge gaps in standardized high-quality RCTs, performance and research of long-term outcomes and health economy comparing different approaches to total hysterectomy in China.
ObjectiveTo investigate the effectiveness of free-style perforator flap in repairing the soft tissue defect of knee.MethodsBetween December 2011 and October 2017, 13 patients with the soft tissue defects of knees were repaired with the free-style perforator flaps. There were 9 males and 4 females, with an average age of 40 years (range, 14-65 years). The injuries were caused by traffic accident in 7 cases, crushing in 4 cases, and falling from height in 2 cases. The soft tissue defects in 9 cases formed after 2 weeks-2 months (mean, 1 month) of lower extremity fractures fixation. The other 4 cases were urgently admitted to the hospital after injury, and the time from injury to admission was 0.5-18.0 hours (mean, 8 hours). The size of soft tissue defect ranged from 3 cm×2 cm to 12 cm×8 cm after debridement. Nine propeller flaps, 6 rotating flaps, and 2 V-Y advanced flaps were used; and 9 cases were repaired by single flap and 4 cases were repaired by combined flaps. The size of flap ranged from 7.5 cm×2.5 cm to 20.0 cm×6.0 cm. The donor sites were sutured directly.ResultsThe flaps survived smoothly and incisions healed by first intention in 12 cases. The congestion occurred in 1 case, which obtained delayed healing after symptomatic treatment. All incisions at donor sites healed by first intention. All patients were followed up 3-24 months with an average of 6 months. The shape and motions of knee were satisfactory.ConclusionThe free-style perforator flap can maximize the utilization of the donor area around the knee wound, with reliable blood supply, small trauma, and easy operation. It is an ideal flap for the soft tissue defect of knee.
Objective To investigate the technique and effectiveness of using narrow hypodermal pedicled retroauricular flap for repairing preauricular soft tissue defect. Methods Between June 2008 and July 2011, 11 cases of preauricular soft tissue defect were treated, which were caused by resection of preauricular tumors, including 5 cases of pigmented nevus, 2 cases of basal cell carcinoma, 2 cases of mixed hemangioma, and 2 cases of skin papilloma. There were 7 males and 4 females, aged from 26 to 75 years (mean, 50 years). The disease duration was 3-50 years (mean, 35 years). The size ofthe soft tissue defect ranged from 1.5 cm × 1.0 cm to 3.5 cm × 3.0 cm. The narrow hypodermal pedicled retroauricular flap was designed with its pedicle along the pathway of the superficial temporal artery and posterior auricular artery through tunnel to repair the defects. The size of the flaps ranged from 1.8 cm × 1.3 cm to 3.8 cm × 3.3 cm with the pedicle of 2-5 cm in length and 0.4-0.7 cm in width. The donor site was sutured directly or repaired with local flap. Results All flaps survived and incisions healed primarily after operation. Eight cases were followed up 6 months to 1 year. The flaps had good texture, flexibil ity, and color, and the auricle appearance was satisfactory. No recurrence of tumor was found. Conclusion The narrow hypodermal pedicled retroauricular flap has long and narrow pedicle, big transferring angle, large repairing area, no major blood vessel, and easy operation, so it is a simple and ideal technique for repairing preauricular soft tissue defect.
