3 This technology depends on: INTRODUCTIONThis technology depends on:Mechanical energy or pressure& electrical energy remodelling of the vessel tissue creating collagen seal out of native vessel protein (denature collagen and elastin in vessel wall).Levy B. & Emery L.

6 INTRODUCTIONA Cochrane review on the surgical approach to hysterectomy for benign gynaecological disease, published in 2006, concluded that:Vaginal hysterectomy should be performed in preference to abdominal hysterectomy, where possible.Johnson N.; Barlow D.; Lethaby A., et al. (2005): Surgical approach to hysterectomy for benign gynaecological disease. Cochrane Database of Systematic Reviews, Issue 2: CD
8 The extent of laparotomy and vaginal surgery should be based on the SurgeonPreference(Indication)Experiencewith abdominal and vaginal surgery
9 vaginal hysterectomyDespite fastest and least expensive it is used in only 23% of the hysterectomies performed in the United States
10 INTRODUCTIONTraditionally, many surgeons have avoided vaginal hysterectomy or used it only in carefully selected patients .WHYKives S.L.; Levy B.S.; Levine R.L., et al. (2003): for the American Association of Gynaecologic Laparoscopists. Laparoscopic-assisted vaginal hysterectomy: J Am Assoc Gynaecol Laparosc: 10:135-8.
11 HAEMOSTASIS.Achieving hemostasis is fundamental in all surgical approaches.clips, staples, sutures, ultrasonic, and monopolar or bipolar coagulation.
12 EBVS electrosurgical bipolar vessel sealing Seals vessels from 1 to 7 mm in diameter,Precise amount of bipolar energy and pressure to fuse collagen and elastin within the vessel walls.withstand a minimum of three times normal systolic pressure.Space requirements are less for EBVS
13 SEALING. Sealing is achieved with minimal sticking and charring. Thermal spread to adjacent tissues is approximately 0.5 to 2 mm.The result is permanent.
14 In a study comparing the electrosurgical bipolar vessel sealing (EBVS) system to ultrasonic coagulation, bipolar coagulation, surgical clips, and sutures,the electrosurgical bipolar vessel sealing (EBVS) system created seals that (were stronger than the other energy-based ligation methods and comparable in strength with that of mechanical ligation techniques. )
15 AIM OF THE WORKTo assess the safety and efficacy of using the electrosurgical bipolar vessel sealing (EBVS) system for securing the pedicles during vaginal hysterectomy in comparison with the conventional method of securing the pedicles by suture ligation & does it permit the expansion of the spectrum of vaginal hysterectomy indications.

17 These new technologies also reduce the risk of adverse reactions: Vessels sealed using autologous tissues are unlikely to have adverse responses to foreign materials, such as sutures, staples, or clips. Finally, the reduction in needle use reduces the potential for injury during vessel ligation. Although in skilled hands vaginal hysterectomy may be performed using standard techniques even in difficult patients, the electrosurgical bipolar vessel sealer technology should permit the less experienced vaginal surgeon an opportunity to expand the indications for vaginal hysterectomy
18 Setting:The study was carried out in Ain-shams University maternity Hospital.Study group:Women admitted for vaginal hysterectomy for benign disease.Type of the study:Prospective randomized Double blind controlled study.
19 Population:Includes 100 patients undergoing vaginal hysterectomy [divided into 4 groups]:Group L1: vaginal hysterectomy using electrosurgical bipolar vessel sealing system (EBVS) for securing the pedicles in the patients with the traditional indications for vaginal hysterectomy.Group S1: vaginal hysterectomy using traditional suturing for securing the pedicles in the patients with the traditional indications for vaginal hysterectomy.Group L2: vaginal hysterectomy using electrosurgical bipolar vessel sealing system (EBVS) for securing the pedicles in the challenging (difficult) vaginal hysterectomies.Group S2: vaginal hysterectomy using traditional suturing for securing the pedicles in the challenging (difficult) vaginal hysterectomies.
20 Inclusion criteria for L1 & S1 groups: 1st or 2nd degree uterine descent.Uterine size < 10 weeks.Benign pathology.Multigravid patients.Vaginal canal should be ample.The posterior & lateral vaginal fornices should be wide and deep.Subpubic angles > 90°.
22 Inclusion criteria for L2 & S2 groups: Benign pathology.No uterine descent.Vaginal canal should be adequate.The posterior & lateral vaginal fornices should be adequate.Subpubic angles = 70-90°.Uterine size weeks or previous uterine operation [caesarean section-myomectomy-surgery involving the tubes or the ovaries].
23 Then each patient in the study will be tested for the following endpoints Operative timeOperative blood lossHospital stay.Any postoperative complications including:1ry haemorrhage.2ry haemorrhage.Postoperative infection and febrile morbidity.The need for readmission.The need for laparotomy
24 PILOT STUDY ON SVH. Started december 2004. Patient fit for vaginal hysterectomy allocated sequentially randomised and blindly into two groups.Comparing the efficacy of bipolar vessel sealing technique with routine vaginal hysterectomy.
27 PATIENTSSample sizeSample size103 Women admitted for vaginal hysterectomy for benign disease were chosen according to calculations that indicated a sample size of 50 subjects in each treatment arm would have 80% power with 95% confidence to detect a 20% difference between procedure times with electrosurgical bipolar vessel sealer versus suture ligature.

34 RESULTSEBVSOperative dataOPERATIVE DATAIn the current study, in about one third (33%) of the cases debulking techniques were required to complete the operation, salpingoophorectomy was done in 20 cases either unilateral or bilateral if needed according to the clinical situation.
35 RESULTSEBVSOperative dataSometimes other gynaecological procedures like classical repair (CR), sacrospinous fixation (SSF), transobturator mesh (TOM) or transvaginal tape (TVT) were done after completing the vaginal hysterectomy for associated gynaecological indications.

40 RESULTSEBVSOperative datathe current study, the intraoperative blood loss was significantly lower in Groups L, and L2 than groups S, and S2 correspondingly, the role of EBVS in reducing the operative blood loss was more pronounced in the difficult cases [Groups L2].
42 Patients who have indications for traditional vaginal hysterectomy do not need abdominal hysterectomy,or laparoscopic hysterectomy.
43 Post operative Pain.Deserves to be studied in a well controlled trial
44 WHY SVH? Good potentials. Easier. Quicker Bloodless. Less infection. Less pain.
45 Intra operative.Time ,Bleeding and recovery are all shorter than average for other techniques.
46 Sutureless vaginal hysterectomy using electrosurgical bipolar vessel sealer is a good alternative to the use of sutures in routine vaginal hysterectomy.
47 When the competent surgeon is equipped with such devices, conversion of an abdominal hysterectomy to the vaginal route is both attainable and preferred.
48 RESULTSEBVSOperative dataIn the current study, the total operative time was significantly shorter in Groups L, L1 and L2 than groups S, S1 and S2 correspondingly and this shorting in the operative time resulted from shorting of the pedicle dissection time in Groups L, L1 and L2.

50 RESULTSPostoperative dataPOSTOPERATIVE DATAThere was no significant statistical difference between the comparison groups as regard the duration of hospital stay.
51 14 patients required hospitalization > 48 hours: RESULTSEBVSPostoperative data14 patients required hospitalization > 48 hours:6 had some medical problems like diabetes mellitus or ischemic heart disease8 had some complications related to the surgery like postoperative fever (4 patients) or major surgical complication (4 patients).
52 RESULTSPostoperative dataThere was no significant statistical difference between the comparison groups as regard the rate of occurrence of complications:
53 pain with EBVS could be related to: Less manipulation, compression and traction.No foreign material;Tissue left distal to the suture or clip (including nerves) can necrose post-operatively and may cause pain and infection.Peirce S.C. & Crawford D.C.
