Laparoscopic Assisted Vaginal Hysterectomy Versus Vaginal Hysterectomy

Introduction: Hysterectomy is the commonest gynecologic operation, performed for malignant and benign conditions. There are many approaches to hysterectomy for benign disease. Studies comparing the techniques have showed that vaginal hysterectomy has benefits in terms of reduced hospital stay, faster recovery and less operating time. Objective: The purpose of this study is to compare the surgical and immediate postoperative outcomes of Laparoscopic Assisted Vaginal Hysterectomy (LAVH) with those of Vaginal Hysterectomy (VH). Methods: Retrospective descriptive study, comparing two groups of women who underwent LAVH or VH in our department during a 24 months period, from January 2009 to December 2010. The two groups were compared regarding age, vaginal deliveries, previous abdominal surgery, uterine and adnexal pathology, intra-operative and post-operative complications, uterus weight, blood loss and number of days until discharge. Results: In our study 42 LAVH and 99 VH were included, with a patient mean age of 47 and 59, respectively. The most frequent indication for hysterectomy was fibroids (80%) for LAVH and POP(58.6%) for HV. In LAVH group 47.6% of patients had previous abdominal surgery, vs 28.2% in VH group. The medium operative time was 167 minutes for LAVH vs 99 minutes for HV. The intra-operative complications were one case (2%) of accidental incision of rectum in LAVH, and one bladder incision in the VH (1%). There were 3 conversions to laparotomy for difficult technique (7%) in LAVH group. There were no significant post-operative complications for LAVH. In VH group there were 2 cases of haemoperitoneum (2%) and 1 case requiring blood transfusion (1%). The mean time for discharge was 4.23 days for LAVH and 4.46 days for VH. Conclusions: In our study, the main advantage for VH was the reduced operative time. In terms of time to discharge there was no difference between the 2 groups. The main intra-operative complication of LAVH was the risk of conversion to laparotomy, but post-operatively this procedure had fewer complications than VH. In conclusion, LAVH is a safe option for women requiring hysterectomy in cases where VH is anticipated to be technically difficult.

Vaginal hysterectomy with the autosuture stapler

Our objective was to assess the applicability of hysterectomy by the vaginal route completely performed with Autosuture staples. Between January 1992 and September 1993, 5 vaginal hysterectomies using Autosuture staplers were performed by the authors. Five vaginal hysterectomies matched for age, parity, and uterine size performed by the same surgeons using reabsorbable sutures during the same period were used as case controls. No febrile morbidity, cuff infections, thrombophlebitis, bladder injury, or hemorrhage complications were observed in the 10 women who entered the study. In summary, vaginal hysterectomy can be performed with Autosutures easily, probably faster with experience, and with less oozing from the operative field, thus providing a safe procedure.

Postoperative analgesic requirements - total laparoscopic hysterectomy versus vaginal hysterectomy

Background: There is limited information available on the requirement for postoperative analgesic drugs in patients submitted to total laparoscopic hysterectomy (TLH) compared with patients undergoing vaginal hysterectomy (VH). Aim: To compare the postoperative analgesic requirements in patients who underwent a TLH with patients who had a VH. Methods: Chart review of 53 patients who had TLH and 47 who had VH and were seen postoperatively by an acute pain management service in order to assess postoperative analgesic requirements. Patient controlled analgesia (PCA) was part of the standard protocol for postoperative pain management. Analgesic requirement was recorded as the mean doses of morphine and number of days that patients used non-steroidal anti-inflammatory drugs (NSAIDs), oxycodone and tramadol. Results: The requirement for total morphine was approximately half the dose in patients who had a TLH (10.8 +/- 12.6 mg) compared with patients who had a VH (19.4 +/- 21.9 mg) (P 0.017). The length of use of NSAIDs was significantly reduced in patients who had undergone a TLH (2.0 +/- 0.95 days) as compared with patients who had a VH (2.85 +/- 1.1 days) (P < 0.0001). Conclusions: Patients submitted to TLH require less postoperative analgesic drugs when compared with patients who had VH. Prospective randomised trials are warranted to compare analgesic requirements between patients submitted to TLH and VH.

Expression of p53, Ki-67, and CD31 in the vaginal margins of radical hysterectomy in patients with stage IB carcinoma of the cervix

Objectives. This study was undertaken to evaluate the expression of p53, Ki-67, and CD31 both in the tumor and in the vaginal margins of radical hysterectomy in patients with stage IB squamous cell carcinoma of the cervix, as an attempt to use these proteins as possible markers for residual tumor in cervical cancer.Methods. Thirty patients with stage IB squamous cell carcinoma of the cervix were submitted to radical hysterectomy (study group), and thirty patients with uterine myoma were submitted to vaginal hysterectomy (control group) and were prospectively studied from November 2001 to September 2002. Tissue samples were taken from the tumor or cervix, anterior vaginal margin (AVM), and posterior vaginal margin (PVM) and were immunohistochemically evaluated by monoclonal antibodies for p53, Ki-67, and CD31. Vaginal samples in which the histological examination showed tumor involvement were excluded from the study.Results. Patient's mean age was 48.7 +/- 10.4 years (27-73 years). The clinical stage was IB1 in 22 patients (73.3%) and IB2 in eight patients (26.7%). The expressions of p53, Ki-67, and CD31 were significantly higher in the tumor than in the benign cervix (P < 0.001). Higher expressions of these markers were noted in the vaginal margins of radical hysterectomy in patients with cervical carcinoma compared to the vaginal margins of control patients. This association was demonstrated for p53 in the AVM proximal (P = 0.045), for Ki-67 in AVM proximal (P < 0.001), AVM distal (P < 0.001), PVM proximal (P = 0.009), and PVM distal (P < 0.001), and for CD31 in AVM proximal (P = 0.003) and AVM distal (P = 0.018). There was no difference in p53, Ki-67, and CD31 expression between the proximal and distal regions of the vaginal margins in patients with carcinoma of the cervix.Conclusion. The expressions of p53, Ki-67, and CD31 were significantly higher in both the histologically positive (cervical tumor) and negative (vaginal margins) tissues of patients who had undergone radical hysterectomy for cervical cancer compared to the benign control tissues.

Telomerase activity in the vaginal margins of radical hysterectomy in patients with carcinoma of the cervix: Correlation with histology and human papillomavirus

This study was undertaken to evaluate the telomerase activity both in the tumor and in the vaginal margins of radical hysterectomy in patients with squamous cell carcinoma (SCC) of the cervix. Thirty-three patients with SCC of the cervix (study group) and 13 patients with uterine myoma (control group) were prospectively studied. Tissue samples were taken from the tumor or cervix, anterior vaginal margin (AVM), and posterior vaginal margin (PVM). The specimens were analyzed by histopathology, by a telomerase PCR-TRAP-ELISA kit, and by polymerase chain reaction using human papillomavirus (HPV) DNA. The telomerase activity was significantly higher in the tumor than in the benign cervix (P < 0.001). There was no difference in telomerase activity in the AVM and PVM in patients with cervical carcinoma compared to the control group. Telomerase activity was associated with the presence of histologic malignancy in the PVM of patients submitted to radical hysterectomy (P = 0.03). This association was not observed with the presence of HPV in AVM or PVM in the study group. Telomerase activity is a marker of histologic malignancy in patients with SCC of the cervix. There was no association between the telomerase activity and the presence of HPV in vaginal margins of patients submitted to radical hysterectomy. © 2006, Copyright the Authors.

Uterine preservation or hysterectomy at sacrospinous colpopexy for uterovaginal prolapse

This study retrospectively compared 34 women who had a sacrospinous hysteropexy and 36 who had a vaginal hysterectomy and sacrospinous fixation for symptomatic uterine prolapse. All women underwent independent review and examination, with a mean follow-up of 36 months in the hysterectomy group and 26 months in the hysteropexy group.  The subjective success rate was 86% in the hysterectomy group and 78% in the hysteropexy group (P = 0.70). The objective success rate was 72% and 74%, respectively (P = 1.00). The patient-determined satisfaction rate was 86% in the hysterectomy group and 85% in the hysteropexy group (P = 1.00). The operating time in the hysterectomy group was 91 minutes, compared to 59 minutes in the hysteropexy group (P

Efectividad de morfina intratecal versus endovenosa / histerectomía vaginal en el Hospital Occidente de Kennedy

Introducción: la histerectomía vaginal es una cirugía frecuente, esta investigación comparo dos vías de suministro de opiáceos: intratecal y endovenosa en un estudio realizado en el Hospital Occidente de Kennedy. Método: Estudio prospectivo observacional comparando dolor utilizando la escala de dolor numérica verbal y determinando los requerimientos de morfina de rescate y o Aines, describiendo la presencia de efectos secundarios del uso de opiáceos en dos grupos. Resultados: Participaron 48 mujeres entre 40 y 65 años con ASA I y II. Manejadas con morfina intratecal fueron 28 y 20 con morfina intravenosa, la dosis intratecal fueron de 80 microgramos y las intravenosas de entre 3 y 5 mg en bolo. El dolor se evaluó a las 6, 12 y 24 horas del procedimiento quirúrgico. A las 6, 12 y 24 horas se encontró diferencia significativa p< 0.0001). Se presentaron 28% que usaron el rescate con intratecal, 100% de los casos con morfina endovenosa lo requirió. El uso de AINES se encontró que solo el 3,6% de los casos manejado con morfina intratecal requirieron uso de AINES en cambio las manejadas con endovenosa fue 80%. El tiempo trascurrido entre la dosis de opiáceos y el requerimiento de morfina tuvo una diferencia que fue significativa (p=0,000008). Las nauseas en 14% y el vomito en 7,1% de los manejados con opiáceos intratecales en cambio con endovenosos tuvieron 70% y 35% respectivamente. Se encontró diferencia significativa en estas dos variables pero no en el prurito, a pesar que se encontró más frecuente en los casos manejados con intratecal. Conclusión: pacientes con morfina intratecal tiene más efecto prolongado de analgesia y es probable que necesiten menos dosis de rescate, con igual nausea, vomito y mas prurito.

Repercussões hemodinâmicas do posicionamento em litotomia exagerada para histerectomia vaginal em paciente cardiopata: relato de caso

JUSTIFICATIVA E OBJETIVOS: A técnica de histerectomia vaginal possibilita menor tempo operatório e o uso do bloqueio do neuro-eixo, com os benefícios de melhor analgesia pós-operatória e menor resposta sistêmica ao procedimento cirúrgico. O objetivo deste relato foi descrever as alterações hemodinâmicas decorrentes do posicionamento em litotomia exagerada em paciente cardiopata. RELATO do CASO: Paciente de 33 anos, G0P0A0, com história de sangramento uterino anormal e anemia. A ultra-sonografia evidenciava útero miomatoso com volume estimado de 420 cm³. Ela era portadora de trombofilia e miocardiopatia dilatada, com passado de dois acidentes vasculares encefálicos isquêmicos e dois infartos agudos do miocárdio. Foi monitorizada com pressão arterial invasiva e cateter de artéria pulmonar com medida de débito cardíaco contínuo. Realizada raquianestesia com bupivacaína hiperbárica e morfina. A paciente foi posicionada em litotomia exagerada sendo realizada histerectomia total pela técnica de Heaney e salpingectomia bilateral. Como intercorrência intra-operatória apresentou diminuição do índice cardíaco e aumento das pressões de câmaras direitas após o posicionamento, necessitando do uso de dobutamina. CONCLUSÕES: O posicionamento em litotomia exagerada pode ocasionar alterações hemodinâmicas que devem ser consideradas na escolha da técnica cirúrgica.

A diagnostically challenging case of ureterovaginal fistula after laparoscopic hysterectomy

A complicated case of iatrogenic ureterovaginal fistula in a 56-year-old woman after laparoscopic-assisted vaginal hysterectomy, which persisted after several attempts of repair including ureterocystoneostomy, is presented. Accurate radiologic work-up enabled us to identify a refluxing ureteral stump, which was not ligated at the time of ureterocystoneostomy, as the origin of urinary leakage. Surgical principles that should be adhered to when managing such complex cases to obtain successful long-lasting outcome are described.

Auditing complications of laparoscopy in a major tertiary hospital in Australia

Objective To review complications in both diagnostic and operative laparoscopic procedures at a university-affiliated major teaching hospital and to assess possible risk factors for complications. Design and setting A retrospective review of all laparoscopic procedures at the Royal Women's Hospital Brisbane, Australia, from 1990 to 1997 inclusive. A non-medical or nursing independent assessor reviewed charts. Data were collected on a standard form. Incomplete charts were excluded from analysis. Results There was a total of 1505 procedures. Analysis was based on 1435 complete data records. The overall complication rate was 2.86% with infection (1.3%) being the most common. The rate of gastrointestinal injury was 0.14%. Compared with women who had diagnostic laparoscopies, a higher rate of complication was found in women who had undergone operative laparoscopic procedures. However, this difference did not reach statistical significance. The complication rate was unrelated to seniority of the surgeon. Conclusion Complications can occur in any laparoscopic procedure. Regular reviews, especially in teaching hospitals, will provide feedback to clinicians to improve quality of care.

PTEN expression in patients with carcinoma of the cervix and its association with p53, Ki-67 and CD31

PURPOSE: To investigate protein expression and mutations in phosphatase and tensin homolog (PTEN) in patients with stage IB cervical squamous cell carcinoma (CSCC) and the association with clinical-pathologic features, tumor p53 expression, cell proliferation and angiogenesis.METHODS:Women with stage IB CSCC (n=20 - Study Group) and uterine myoma (n=20 - Control Group), aged 49.1±1.7 years (mean±standard deviation, range 27-78 years), were prospectively evaluated. Patients with cervical cancer were submitted to Piver-Rutledge class III radical hysterectomy and pelvic lymphadenectomy and patients in the Control Group underwent vaginal hysterectomy. Tissue samples from the procedures were stained with hematoxylin and eosin for histological evaluation. Protein expression was detected by immunohistochemistry. Staining for PTEN, p53, Ki-67 and CD31 was evaluated. The intensity of PTEN immunostaining was estimated by computer-assisted image analysis, based on previously reported protocols. Data were analyzed using the Student's t-test to evaluate significant differences between the groups. Level of significance was set at p<0.05.RESULTS:The PTEN expression intensity was lower in the CSCC group than in the Control (benign cervix) samples (150.5±5.2 versus 204.2±2.6; p<0.001). Our study did not identify any mutations after sequencing all nine PTEN exons. PTEN expression was not associated with tumor expression of p53 (p=0.9), CD31 (p=0.8) or Ki-67 (p=0.3) or clinical-pathologic features in patients with invasive carcinoma of the cervix.CONCLUSIONS: Our findings demonstrate that the PTEN protein expression is significantly diminished in CSCC.

A practical approach to a multi-level analysis with a sparse binary outcome within a large surgical trial

Objectives: To assess the potential source of variation that surgeon may add to patient outcome in a clinical trial of surgical procedures. Methods: Two large (n = 1380) parallel multicentre randomized surgical trials were undertaken to compare laparoscopically assisted hysterectomy with conventional methods of abdominal and vaginal hysterectomy; involving 43 surgeons. The primary end point of the trial was the occurrence of at least one major complication. Patients were nested within surgeons giving the data set a hierarchical structure. A total of 10% of patients had at least one major complication, that is, a sparse binary outcome variable. A linear mixed logistic regression model (with logit link function) was used to model the probability of a major complication, with surgeon fitted as a random effect. Models were fitted using the method of maximum likelihood in SAS((R)). Results: There were many convergence problems. These were resolved using a variety of approaches including; treating all effects as fixed for the initial model building; modelling the variance of a parameter on a logarithmic scale and centring of continuous covariates. The initial model building process indicated no significant 'type of operation' across surgeon interaction effect in either trial, the 'type of operation' term was highly significant in the abdominal trial, and the 'surgeon' term was not significant in either trial. Conclusions: The analysis did not find a surgeon effect but it is difficult to conclude that there was not a difference between surgeons. The statistical test may have lacked sufficient power, the variance estimates were small with large standard errors, indicating that the precision of the variance estimates may be questionable.

Increased proximal urethral sensory threshold after radical pelvic surgery in women

AIM: To identify factors that potentially influence urethral sensitivity in women. PATIENTS AND METHODS: The current perception threshold was measured by double ring electrodes in the proximal and distal urethra in 120 women. Univariate analysis using Kaplan-Meier models and multivariate analysis applying Cox regressions were performed to identify factors influencing urethral sensitivity in women. RESULTS: In univariate and multivariate analysis, women who had undergone radical pelvic surgery (radical cystectomy n = 12, radical rectal surgery n = 4) showed a significantly (log rank test P < 0.0001) increased proximal urethral sensory threshold compared to those without prior surgery (hazard ratio (HR) 4.17, 95% confidence interval (CI) 2.04-8.51), following vaginal hysterectomy (HR 4.95, 95% CI 2.07-11.85), abdominal hysterectomy (HR 5.96, 95% CI 2.68-13.23), or other non-pelvic surgery (HR 4.86, 95% CI 2.24-10.52). However, distal urethral sensitivity was unaffected by any form of prior surgery. Also other variables assessed, including age, concomitant diseases, urodynamic diagnoses, functional urethral length, and maximum urethral closure pressure at rest had no influence on urethral sensitivity in univariate as well as in multivariate analysis. CONCLUSIONS: Increased proximal but unaffected distal urethral sensory threshold after radical pelvic surgery in women suggests that the afferent nerve fibers from the proximal urethra mainly pass through the pelvic plexus which is prone to damage during radical pelvic surgery, whereas the afferent innervation of the distal urethra is provided by the pudendal nerve. Better understanding the innervation of the proximal and distal urethra may help to improve surgical procedures, especially nerve sparing techniques. Neurourol. Urodynam. (c) 2006 Wiley-Liss, Inc.

Quality of pain treatment after caesarean section: Results of a multicentre cohort study.

BACKGROUND A large cohort study recently reported high pain scores after caesarean section (CS). The aim of this study was to analyse how pain after CS interferes with patients' activities and to identify possible causes of insufficient pain treatment. METHODS We analysed pain scores, pain-related interferences (with movement, deep breathing, mood and sleep), analgesic techniques, analgesic consumption, adverse effects and the wish to have received more analgesics during the first 24 h after surgery. To better evaluate the severity of impairment by pain, the results of CS patients were compared with those of patients undergoing hysterectomy. RESULTS CS patients (n = 811) were compared with patients undergoing abdominal, laparoscopic-assisted vaginal or vaginal hysterectomy (n = 2406, from 54 hospitals). Pain intensity, wish for more analgesics and most interference outcomes were significantly worse after CS compared with hysterectomies. CS patients with spinal or general anaesthesia and without patient-controlled analgesia (PCA) received significantly less opioids on the ward (62% without any opioid) compared with patients with PCA (p < 0.001). Patients with PCA reported pain-related interference with movement and deep breathing between 49% and 52% compared with patients without PCA (between 68% and 73%; p-values between 0.004 and 0.013; not statistically significant after correction for multiple testing). CONCLUSION In daily clinical practice, pain after CS is much higher than previously thought. Pain management was insufficient compared with patients undergoing hysterectomy. Unfavourable outcome was mainly associated with low opioid administration after CS. Contradictory pain treatment guidelines for patients undergoing CS and for breastfeeding mothers might contribute to reluctance of opioid administration in CS patients.
