Pelvic organ function in randomized patients undergoing laparoscopic or abdominal hysterectomy

A Systematic Review of Clinical Trials Assessing Sexuality in Hysterectomized Patients

In hysterectomized patients, even though there is still controversy, evidence indicates that in the short term, the vaginal approach shows benefits over the laparoscopic approach, as it is less invasive, faster and less costly. However, the quality of sexual life has not been systematically reviewed in terms of the approach adopted. Through a systematic review, we analyzed (CRD42020158465 in PROSPERO) the impact of hysterectomy on sexual quality and whether there are differences according to the surgical procedure (abdominal or vaginal) for noncancer patients. MEDLINE (through PubMed), Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Scopus were reviewed to find randomized clinical trials assessing sexuality in noncancer patients undergoing total hysterectomy, comparing vaginal and abdominal (laparoscopic and/or open) surgery. Three studies that assessed the issue under study were finally included. Two of these had a low risk of bias (Cochrane risk of bias tool); one was unclear. There was significant variability in how sexuality was measured, with no differences between the two approaches considered in the review. In conclusion, no evidence was found to support one procedure (abdominal or vaginal) over another for non-oncological hysterectomized patients regarding benefits in terms of sexuality.

Vaginal, sexual and urinary symptoms following hysterectomy: a multi-centre randomized controlled trial

Background

Hysterectomy is the most common major gynaecological procedure. The aim of this study was to study vaginal, sexual and urinary symptoms following total abdominal hysterectomy (TAH), non-descent vaginal hysterectomy (NDVH) and total laparoscopic hysterectomy (TLH) in a low resource setting.

Methods

A multi-centre randomized controlled trial (RCT) was conducted in two public sector hospitals in Sri Lanka. Participants were patients requiring hysterectomy for non-malignant uterine causes. Exclusion criteria were uterus> 14 weeks, previous pelvic surgery, medical illnesses which contraindicated laparoscopic surgery, and those requiring incontinence surgery or pelvic floor surgery.

Vaginal, sexual function and urinary symptoms were assessed by the validated translations of ICIQ-VS and ICIQ-FLUTS questionnaires. Post-operative improvement (pre-operative – post-operative) was assessed.

Results

There was an improvement (median (IQ1-IQ3) in vaginal symptoms [TAH 6(2–8) vs 4(0–8), p < 0.001; NDVH 6(4–8.5) vs 5(0–8), p < 0.001; TLH 4(2–10.5) vs 4(0–10), p < 0.001], urinary flow symptoms [TAH 2(1–4) vs 1 (0–3), p < 0.001; NDVH 3 (2–5) vs 2 (0.5–4), p < 0.001; TLH 1(1–4) vs 1(0–3), p < 0.05], urinary voiding symptoms [TAH 0(0–0) vs 0(0–0), p = 0.20; NDVH 0(0–1) vs 0(0–0.8), p < 0.05; TLH 0(0–0) vs 0(0–0), p < 0.05] and urinary incontinence symptoms [TAH 0(0–2) vs 0(0–2), p = 0.06; NDVH 0(0–3) vs 0(0–3), p < 0.001; TLH 0(0–3) vs 0(0–2), p < 0.05] at 1-year (TAH n = 47, NDVH n = 45, TLH n = 47). There was an improvement in sexual symptoms only in the TLH group [TAH 0(0–11.5) vs 0(0–14), p = 0.08); NDVH 0(0–0) vs 0(0–0), p = 0.46; TLH 0(0–0) vs 0(0–4), p < 0.05].

There was no significant difference among the three different routes in terms of vaginal symptoms score [TAH 2 (0–2), NDVH 0 (0–2), TLH 0 (0–2), p = 0.33], sexual symptoms [TAH 0 (0–0), NDVH 0 (0–0), TLH 0 (0–0), p = 0.52], urinary flow symptoms [TAH 0 (0–1), NDVH 0 (0–1), TLH 0 (0–2), p = 0.56], urinary voiding symptoms [TAH 0 (0–0), NDVH 0 (0–0), TLH 0 (0–0), p = 0.64] and urinary incontinence symptoms [TAH 0 (0–0), NDVH 0 (0–1), TLH 0 (0–1), p = 0.35] at 1-year.

Conclusions

There was a post-operative improvement in vaginal symptoms and urinary symptoms in all three groups. There was no significant difference in pelvic organ symptoms between the three routes; TAH, NDVH and TLH.

Comparison of the short-term and long-term outcomes of laparoscopic hysterectomies and of abdominal hysterectomies: a case study of 4,895 patients in the Guangxi Zhuang Autonomous Region, China

BACKGROUND

To evaluate the short-term and long-term outcomes after laparoscopic hysterectomy (LH) compared with abdominal hysterectomy (AH) in case of benign gynecological disease.

METHODS

A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies (3,539 LH vs.1,356 AH) between 2007 and 2013 was involved. Operative time (OT), estimated blood loss (EBL), intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed.

RESULTS

The EBL (174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively), passing flatus (38.7±14.1 vs. 48.1±13.2 hours), days with indwelling catheter (1.5±0.6 vs. 2.2±0.8 days), use of analgesics (6.5% vs. 73.1%), intra-operative complication rate (2.4% vs. 4.1%), post-operative complication rate (2.3% vs. 5.7%), post-operative constipation (12.1% vs. 24.6%), mild and serious stress urinary incontinence (SUI) post-operative (P<0.001; P=0.014), and proportion of Female Sexual Functioning Index (FSFI) total score <26.55 post-operative (P<0.001) of the LH group were significantly less than those of AH group. There were no significant differences in OT (106.5±34.5 vs. 106.2±40.3 min) between the two groups.

CONCLUSIONS

LH is a safe and efficient operation for improving patients?long-term quality of life (QoL), and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus.

Feasibility and Safety of Video Endoscopic Inguinal Lymphadenectomy in Vulvar Cancer: A Systematic Review

OBJECTIVE

To systematically review previous studies and to evaluate the feasibility and safety of video endoscopic inguinal lymphadenectomy (VEIL) in vulvar cancer.

METHODS

We conducted a comprehensive review of studies published through September 2014 to retrieve all relevant articles. The PubMed, EMBASE, Web of Science, Cochrane Library, Wan Fang Data and Chinese National Knowledge Infrastructure databases were systematically searched for all relevant studies published in English or Chinese through September 2014. Data were abstracted independently by two reviewers, and any differences were resolved by consensus.

RESULTS

A total of 9 studies containing 249 VEIL procedures involving 138 patients were reviewed. Of the 249 VEIL procedures, only 1 (0.4%) was converted to an open procedure for suturing because of injury to the femoral vein. The range of operative time was 62 to 110 minutes, and the range of estimated blood loss was 5.5 to 22 ml. The range of the number of harvested lymph nodes was 7.3 to 16. The length of hospital stay varied from 7 to 13.6 days across reports. The incidence of lymph node metastasis was 19.7% (27/138), and the recurrence rate was 4.3% (3/70) within 3 to 41 months of follow-up. One or more short-term complications were documented in 18 of 138 (13.0%) patients. Complications after VEIL were observed in 14 (10.13%) patients and in 15 (6.0%) of the VEIL cases, including major lymphocyst formation in 9 (3.6%), lymphorrhea in 2 (0.8%), inguinal wound infection without wound breakdown in 3 (1.2%) and lymphedema in 1 (0.4%).

CONCLUSIONS

VEIL appears to be a feasible procedure in the management of vulvar cancer. There may be potential benefits that result in lower morbidity compared to traditional methods, but this has yet to be objectively proven.

Does previous pelvic surgery hasten the onset of clinically bothersome urodynamic stress incontinence?

OBJECTIVE

To study the impact of previous pelvic surgery on the onset of clinically bothersome urodynamic stress incontinence (USI).

STUDY DESIGN

Retrospective case-cohort study at a District General Hospital of 305 women undergoing surgery for urodynamic stress incontinence: case note and computer records review of patients undergoing USI surgery. The main outcome measures were age at index USI surgery, and duration from previous pelvic surgery to index surgery.

RESULTS

305 women were included, of whom 118 had previous pelvic surgery including abdominal hysterectomy (TAH) (n=74), vaginal hysterectomy (n=23), anterior colporrhaphy (n=27) and posterior colporrhaphy (n=25). The mean age in the previous surgery group was 62.4 years (95% CI 60.2-64.6, range 32-87) and 53.2 years in the no previous surgery group (95% CI 51.4-55, range 30-88). There were no differences in the mean BMI (28.4 vs. 27.5), or mean parity (2.4 vs. 2.5). The median duration from previous surgery to the index USI surgery was 222 months (abdominal hysterectomy), 96 months (vaginal hysterectomy), 78 months (anterior colporrhaphy), and 72 months (posterior colporrhaphy).

CONCLUSION

Previous pelvic surgery does not seem to accelerate the onset of USI, as women without previous pelvic surgery presented at a significantly earlier age (53.2 years) with clinically bothersome USI than those who had previous surgery (62.4 years). Posterior colporrhaphy had the shortest interval to index USI surgery amongst previous operations.

Bowel dysfunction after total abdominal hysterectomy for benign conditions: a prospective longitudinal study

BACKGROUND AND AIM

On the basis of retrospective studies, hysterectomy has been considered a risk factor for functional bowel disorders. The aim of this study was to prospectively evaluate the patients' bowel function and general health-related quality of life (QoL) before and after hysterectomy. Our hypothesis was that hysterectomy in properly selected patients can impact positively on the patients' self-reporting of their general health and bowel function.

MATERIALS AND METHODS

A prospective longitudinal observational study was conducted in a university-based teaching hospital. Eighty-five patients who were scheduled for total abdominal hysterectomy for a nonmalignant cause completed the study. The main outcome measure was the patient's perception of her bowel function, which was assessed preoperatively and at 6, 12, 26 and 52 weeks postoperatively using the gastrointestinal quality of life questionnaire. The patient's general health was also assessed using a generic general health questionnaire (EQ5D and EQVAS). The effect of time on change in questionnaire score was assessed using mixed model repeated measures at a significance level of 0.05.

RESULTS

The scores in the three questionnaires declined significantly at 6 weeks postoperatively as compared with those obtained preoperatively. However, there was a subsequent increase in the scores up to 12 months postoperatively. Smoking and use of laxative were identified as potential confounding variables.

CONCLUSION

Apart from a transient negative effect, total abdominal hysterectomy improves the patient's gastrointestinal-related QoL, probably as part of general improvement in their QoL.

Laparoscopic treatment of endometrial cancer: systematic review

The objective of this review was to assess the efficacy and safety of laparoscopy compared with laparotomy for treatment of endometrial cancer. Trials were identified by searching the Cochrane Gynecological Cancer Collaborative Review Group Trial Register, MEDLINE, EMBASE, PubMed, BIOSIS Previews, the China Biological Medicine Database, China National Knowledge Infrastructure Whole Article Database, Wan Fang Data, and VIP Information, from January 1991 to May 2012, as well as the Cochrane Central Register of Controlled Trials (Cochrane Library, issue 5, 2012). We also hand searched unpublished and gray literature, reference lists of identified studies, gynecologic cancer handbooks, and conference abstracts. All randomized controlled trials (RCTs) comparing laparoscopic surgery with laparotomy for treatment of all stages of endometrial cancer were selected. Data extraction was performed independently by 2 review authors who assessed study quality and extracted data. The whole articles were assessed for method quality by using the Cochrane Collaboration Back Review Group method quality criteria. Heterogeneity between studies was assessed using the I2 statistic, which estimates the percentage of heterogeneity between trials. The outcomes were pooled statistically when no clinical heterogeneity was apparent. For time to event data, hazard ratios were pooled using the generic inverse variance facility of RevMan 5. Random effects models were used for all meta-analyses. The search yielded 9 eligible RCTs (1361 laparotomy and 2255 laparoscopy). There was no significant difference between laparoscopic and laparotomic approaches to endometrial cancer in 3-year overall survival (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.49 to 1.71; p = .77), 3-year disease-free survival (OR, 0.95; 95% CI, 0.29 to 1.80; p = .89), recurrence at 3-year follow-up (OR, 1.11; 95% CI, 0.60 to 2.06; p = .74), and pelvic node yield (mean difference [MD, 0.45; 95% CI, -0.41 to 1.32; p = .30). The benefits of laparoscopic surgery vs laparotomy were shorter length of hospital stay (MD, -3.42; 95% CI, -3.81 to -3.03; p < .01), and lower rates of postoperative complications (OR, 0.62; 95% CI, 0.52 to 0.73; p < .01). Disadvantages were higher rates of intraoperative complications (OR, 1.35; 95% CI, 1.05 to1.74; p = .02) and longer duration of surgical procedures (MD, 32.73; 95% CI, 16.34 to 49.13; p < .01). We conclude that, compared with laparotomy, laparoscopic surgery seems to be beneficial in women with endometrial cancer, in particular insofar as postoperative complications and length of hospital stay. However, more well-designed RCTs are needed to assess the long-term clinical outcomes, in particular the quality of life.

A series of 3190 laparoscopic hysterectomies for benign disease from 1990 to 2006: evaluation of complications compared with vaginal and abdominal procedures

OBJECTIVE

The aim of this study was to evaluate the complication rate after laparoscopic total hysterectomy and laparoscopic subtotal hysterectomy (LASH) in case of benign disease.

DESIGN

All complications were prospectively recorded at the time of surgery and analysed retrospectively.

SETTING

University hospital.

POPULATION

Among 4505 hysterectomies performed by the same team using the same techniques between 1990 and 2006, 3190 were performed by laparoscopy, 906 by the vaginal route and 409 by laparotomy.

METHODS

Laparoscopic hysterectomies, defined as laparoscopic subtotal hysterectomy (LASH) and total laparoscopic hysterectomy [laparoscopy-assisted vaginal hysterectomy (LAVH) switched to total laparoscopic hysterectomy (TLH) in 2000], were compared with vaginal and abdominal hysterectomies.

MAIN OUTCOME MEASURES AND RESULTS

Since the early 1990s, the number of laparoscopic procedures has continued to grow, while the number of abdominal and vaginal procedures has decreased. Both minor complications (fever >38.5 degrees C after 2 days, bladder incision of <2 cm and iatrogenic adenomyosis) and major complications (haemorrhage, vesicoperitoneal fistula, ureteral injury, rectal perforation or fistula) have been observed during the surgical procedure itself and postoperatively. In the LASH group (n = 1613), the minor complication rate was 0.99% (n = 16) and the major complication rate 0.37% (n = 6). In the total laparoscopic hysterectomy (LAVH/TLH) group (n = 1577), the minor complication rate was 1.14% (n = 18) and the major complication rate 0.51% (n = 8). In the vaginal hysterectomy group (n = 906), minor and major complication rates were 0.77% (n = 7) and 0.33% (n = 3), respectively. In the abdominal hysterectomy group (n = 409), minor and major complication rates were 0.73% (n = 3) and 0.49% (n = 2), respectively.

CONCLUSION

The results from our series of 4505 women clearly show that, in experienced hands, laparoscopic hysterectomy is not associated with any increase in major complication rates.

Clinimetric properties of 3 instruments measuring postoperative recovery in a gynecologic surgical population

BACKGROUND

General, health-related quality-of-life questionnaires and recovery-specific questionnaires have been used to measure recovery in surgical patients. The aim of this study was to evaluate the clinimetric properties of 3 recovery instruments and to examine whether recovery-specific instruments are useful.

METHODS

The Quality of Recovery-40 (QoR-40), Recovery Index-10 (RI-10), and RAND-36 health survey were used to measure recovery in women undergoing different types of hysterectomy in the first 12 weeks after operation. Construct validity was assessed by testing predefined hypotheses. The changes observed during the postoperative period were used as indicators for responsiveness.

RESULTS

One hundred and sixty-one women were included. Response rate and internal consistency were found satisfactory. The highest number of hypotheses used for assessment of construct validity was confirmed in the RI-10. The RI-10 was more responsive compared with the QoR-40 and the RAND-36.

CONCLUSIONS

Because construct validity and responsiveness were greatest in the RI-10, we conclude that this short recovery-specific instrument is useful in studies evaluating postoperative recovery. We recommend the use of the RI-10, unless the immediate postoperative days are of interest in which the QoR-40 was valid.
