Hypertrophic cervical elongation: clinical and histological correlations

A systematic review of uterine cervical elongation and meta-analysis of Manchester repair

OBJECTIVE

This review aims to consolidate current research on cervical elongation, a common but often overlooked complication in pelvic organ prolapse and hysteropexy procedures. It seeks to define, diagnose, and manage cervical elongation, aiming to establish standardized criteria and strategies to enhance clinical outcomes for this condition.

DATA SOURCES

A comprehensive search of the PubMed/MEDLINE, Cochrane Library, and Web of Science databases was executed utilizing the keywords: "cervical elongation," "long cervix uteri," "Manchester," and "cervical amputation". Data were gathered and organized in an Excel spreadsheet, with the analysis conducted according to each category, methodology, or reference range.

STUDY ELIGIBILITY CRITERIA

All types of study designs with full-text availability, including randomized controlled trials, cohort studies, case-control studies, case reports, and systematic reviews, were considered for inclusion. Included studies were fully accessible in English and focused on the topic of interest. Exclusions were made for studies addressing cervical elongation not pertinent to pelvic organ prolapse, and publications such as secondary analyses, case reports, literature reviews, and opinion papers.

RESULTS

Out of 108 relevant studies, only 63 defined their inclusion criteria; of these, 57 were utilized for the narrative review and 8 were used in a meta-analysis comparing the Manchester operation with vaginal hysterectomy. Magnetic Resonance Imaging offers the highest sensitivity in measuring cervical elongation, its practical limitations and high cost necessitate the use of the more feasible Pelvic Organ Prolapse Quantification System (POP-Q), particularly effective for stage 2 and 3 prolapse cases. The POP-Q point C emerges as a pivotal marker for identifying cervical elongation, with specific measurements indicating the condition's presence. The Manchester-Fothergill procedure presents a viable management option for isolated cervical elongation, showing fewer complications and comparable recurrence rates to vaginal hysterectomy.

CONCLUSION

This review highlights the diagnostic and definitional diversity of cervical elongation within populations experiencing pelvic organ prolapse. It emphasizes the critical role of preoperative cervical evaluation, particularly in patients with uterine descensus for selecting the most appropriate surgical intervention.

A novel technique for the measurement of cervical length in non-pregnant women

Introduction

Cervical elongation is considered a risk factor for pelvic organ prolapse treatment failure in uterine preservation surgery. Consensus has not been reached regarding what is considered a normal cervical length, or how to measure it. Our primary aim was to test a new technique for measuring cervical length.

Materials and Methods

We enrolled women undergoing hysterectomy, with or without pelvic organ prolapse (for all indications except cervical tumours/history of cervical operations). Their cervical lengths were measured both by ultrasound and anatomical measurement. The external length of the cervix was measured using Doppler location of the uterine artery near the cervical-uterine junction as the proximal point and compared to the ultrasound measurement of the cervical canal. The uterine specimen was used to record anatomical cervical measurements as well as uterine corpus length. Baseline characteristics such as age, body mass index and pelvic organ prolapse quantification were also collected.

Results

Twenty women were eligible for evaluation. We found the average anatomical cervical canal length was (ccAN) 33.95 mm (range ±  9.23) and by external measurement (ceAN) 36.80 mm (range ± 7.54). We found a significant, high-powered correlation between our ultrasound and anatomical measurements in both techniques, as well as between the two ultrasound techniques. We also found a negative correlation between cervical length and women's age (rp = -0.443, P = 0.05).

Conclusion

Transvaginal ultrasound measurement of cervical length using the location of the uterine artery was found to have a strong correlation to the anatomical cervical length and can be used for the measurement of normal cervical length.

The Manchester operation - is it time for it to return to our surgical armamentarium in the twenty-first century?

We conducted a study to assess the efficacy and outcome results of Manchester operation for women with symptomatic elongation of uterine cervix between 2010 and 2020. Forty-five women were enrolled. Mean age was 54.2 ± 10.5 years, 57.5% were premenopausal. Mean follow up was 4.53 years. Most patients were pleased from the surgery: 29 (76.3%) very pleased and three (7.9%) quite pleased. There were four cases of late postoperative complications: hematometra, pyometra, vesicovaginal fistula and small bowel evisceration through the posterior vaginal fornix. All four cases required surgical interventions with complete recovery. Manchester operation is an effective procedure for symptomatic elongation of uterine cervix. The surgery is short, minimal blood loss and without significant intraoperative complications. However, it is not free of late postoperative complications and it is therefore important that the surgery will be carried out with a strict technique and by skilled surgeons who are capable to manage unique postoperative complications.Impact StatementWhat is already known on this subject? Elongation of the uterine cervix is a condition that has not been sufficiently studied. Up-to-date data regarding the efficacy and safety of the Manchester operation for patients with cervical elongation and normal pelvic support are scarce, as most previously published studies included mainly patients with uterine prolapse.What do the results of this study add? The present study presents the efficacy, complications and clinical outcomes of Manchester operation for women with elongation of the uterine cervix. Our results show that Manchester operation is safe, effective method for symptomatic uterine cervix elongation.What are the implications of these findings for clinical practice and/or further research? This suggests Manchester operation is an effective procedure for symptomatic uterine cervix elongation should be implemented more widely. It must be carried out with a strict technique by skilled surgeons capable to manage unique postoperative complications.

Clinical Risk Factors for Uterine Cervical Elongation among Women with Pelvic Organ Prolapse

Background: Cervical elongation is commonly associated with pelvic organ prolapse (POP). It was an identified risk for recurrent prolapse after hysteropexy, requiring additional surgeries. The aim of the study is to investigate the risk factors for uterine cervical elongation among women with POP. Methods: In this single-center retrospective cohort study, women who underwent vaginal total hysterectomy for POP between 2014 and 2016 were collected. The cervical and total uterine lengths were measured by pathologists, while the ratio of cervical length to total uterine length were calculated. The cervical elongation is defined as corpus/cervix ratio ≤ 1.5. Results: A total of 133 patients were enrolled in this study. Among these patients, 43 women had cervical elongation and 90 women had normal length of uterine cervix. We found that age > 65 years old (67.4% vs. 42.2%, p = 0.007), total vaginal length ≥ 9.5 cm (65.1% vs. 45.6%, p = 0.035), uterine weight < 51 gm (72.1% vs. 52.2%, p = 0.03), and Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6) ≥ 12 (30.2% vs. 14.4%, p = 0.032) were associated with the risk of cervical elongation. There were no significant differences on preoperative urodynamic parameters in the two groups. Conclusion: The patient age > 65 years old, the total vaginal length of POP-Q system ≥ 9.5 cm, uterine weight < 51 g, and POPDI-6 ≥ 12 are independent risk factors of cervical elongation in women with POP. For women scheduled for pelvic reconstructive hysteropexy, concomitant cervical amputation should be considered.

Correlation Between Hypertrophic Cervical Elongation and Pelvic Organ Prolapse

OBJECTIVES

The association between hypertrophic cervical elongation and pelvic organ prolapse (POP) has been observed, but causation has not been determined. This study assessed the relationship of POP with hypertrophic cervical elongation according to menopausal status and the pelvic compartment involved in prolapse.

METHODS

This retrospective single-center case-control study was conducted at Shengjing Hospital of China Medical University between January 2017 and May 2019. Transverse and anteroposterior diameter of the cervix and cervical length were obtained by manual intravaginal measurement for 508 patients with POP and 510 patients without POP. Data were analyzed based on POP compartment and menopausal status.

RESULTS

In the premenopausal group, there was a statistically significant difference in the proportion of patients with hypertrophic cervical elongation in the non-POP and POP groups (P < 0.05); However, among postmenopausal patients, there was no statistical significance between these groups (P > 0.05). Patients with apical compartment POP had a higher proportion of occurrence of hypertrophic cervical elongation than those with nonapical compartment POP (P < 0.05).

CONCLUSIONS

Hypertrophic cervical elongation in premenopausal patients is significantly associated with POP; in particular, there is a significant correlation between apical compartment POP and hypertrophic cervical elongation.

Anatomical Distance From the Cervicovaginal Junction to the Uterovesical Peritoneal Reflection

OBJECTIVE

The objective of this study was to measure the anatomical distance from the cervicovaginal junction to the uterovesical peritoneal reflection (CJ-PR).

METHODS

A total of 120 hysterectomy patients were selected as study subjects. The uterus was removed, and the CJ-PR distance was immediately measured. For total vaginal hysterectomy, measurement was performed intraoperatively. The cervical length was also measured postoperatively.

RESULTS

The median (interquartile) CJ-PR distance for all subjects was 3.3 (2.9-3.7) cm. Comparison of premenopausal and postmenopausal women without prolapse revealed median CJ-PR distances of 3.3 (3.0-3.6) cm and 3.0 (2.6-3.4) cm, respectively. The CJ-PR distance was longer in women with prolapse (4.6 [3.7-5.6] cm) than in those without prolapse (3.2 [2.8-3.6] cm). The median cervical lengths were 3.1 (2.7-3.6) cm for postmenopausal patients without prolapse and 4.4 (3.6-5.8) cm for postmenopausal patients with prolapse.

CONCLUSIONS

Knowledge of the CJ-PR distance may help gynecologists predict how far the uterovesical PR is from the anterior vaginal incision.

Hegde's Modification of Fothergill Surgery for Cervical Elongation: A 7-Year Retrospective Review

OBJECTIVE

This study aimed to evaluate the efficacy of Hegde's modification of Fothergill surgery, an innovative procedure for cervical elongation (CE), and to report perioperative challenges and follow-up.

METHODS

This is a retrospective review of data from 12 patients who underwent successful repair of CE by Hegde's modification of Fothergill surgery from June 2012 to May 2019. Primary outcomes were cervical viability and stenosis. Secondary outcomes were perioperative complications, Pelvic Organ Prolapse Quantification system (POP-Q) measurement and staging, recurrence, conception rates, and World Health Organization Quality of Life (QOL) BREF (WHOQOL-BREF) scores.

RESULTS

All women had a viable, patent cervix at 1-month follow-up. Perioperative complications included total intraoperative blood loss (>50 mL) and febrile morbidity (both 16.7%) and urinary tract infections (8.3%). The mean reduction of point C was 5.78 cm (2.87 ± 0.13 cm to -2.91 ± 1.55 cm). Recurrence was noted in 1 patient (8.3%) who had POP-Q stage 2 prolapse at 6 and 12 months of follow-up. The conception rate was 8.3% at 12 months. All women conceived spontaneously. Mean preoperative WHOQOL-BREF scores improved in all 4 domains, with major improvement seen in the physical domain, from 24.66 ± 8.18 to 70.91 ± 11.01, 19.0 ± 6.48 to 54.92 ± 8.21, 9.33 ± 7.46 to 59.33 ± 14.33, and 19.0 ± 4.89 to 47.07 ± 7.14, for the physical, psychological, social, and environmental domains, respectively.

CONCLUSION

Hegde's modification of Fothergill surgery can be considered as a surgical option for the repair of isolated CE with a healthy cervix in women who desire uterine preservation with the major advantage of preventing cervical stenosis.

Diagnostic value of preoperative ultrasonography, cervical length measurement, and POP-Q examination in cervical elongation estimation

INTRODUCTION AND HYPOTHESIS

Cervical elongation (CE) has not been clearly defined and has similar symptoms to pelvic organ prolapse. We aimed to evaluate the diagnostic value of preoperative POP-Q examinations, ultrasonographic measurements, and direct cervical length measurement with a Foley catheter in predicting CE on postoperative hysterectomy specimens.

METHODS

Fifty-six patients who underwent vaginal hysterectomy for apical pelvic organ prolapse were included. The patients were divided into two groups based on the hysterectomy specimens' corpus/cervix ratio (CCR) as follows: the non-CE group, CCR > 1; the CE group, CCR < 1. The preoperative direct cervical length measurement was performed using 10-French Foley catheters. The recommended cutoff values and sensitivity/specificity analysis of the cervical measurements with Foley, ultrasound, and C-D measurements according to POP-Q were determined by the receiver-operating characteristic analysis.

RESULTS

There were 13 patients (23%) in the non-CE group and 43 patients (76%) in the CE group. The mean cervical measurements with Foley catheter and ultrasound, C-D diameter, and postoperative cervix measurements were 49.4 ± 12.6 mm, 42.14 ± 9.4 mm, 41.4 ± 17.2 mm, and 49.5 ± 13 mm, respectively. Cervical measurement with a Foley catheter had 65% sensitivity and 62.5% specificity with a 47.5-mm cutoff value. Among these preoperative measurements, Foley catheter measurements were the most compatible with postoperative cervical measurements. There was no significant association between CE and age, body mass index, menopause duration, point C, and point D.

CONCLUSION

Cervical length measurement with a Foley catheter may be preferred for estimation of CE.

Secondary cervical elongatio due to large Gartner cyst: A rare case

INTRODUCTION

The exact mechanism by which pelvic tissues lose their anatomic support and undergo descent through the genital hiatus remains elusive. In this case, large Gartner cyst causes secondary cervix elongatio due to the weight of the cyst. Gartner cyst arise from the remnants of the mesonephric ducts. They are typically located in the anterolateral wall and are small. The rarity of this case is very interesting because of the mass size reaches 15 cm and causes cervical elongation.

PRESENTATION OF CASE

This article report a case of 37 years old women who complained large mass came out from vagina. Patient was diagnosed with large anterior vaginal cyst and cervical elongatio. Ultrasound finding suggested that the cyst was originated from anterior wall of vagina in accordance with Gartner cyst. Patient underwent cyst excision, there was no connection between the cyst and urethra. Operation was continued with Manchester Forthegill to restore normal anotomy of the cervix.

DISCUSSION

Secondary cervical elongatio in this case was caused by large Gartner cyst, eventhough there are possibility involvement of other factors. Cervical elongatio plays important role in the decision of operation in this case after removal vaginal cyst.

CONCLUSION

Secondary cervix elongation due to Large Gartner cyst is rare condition. Enlarge cyst causes secondary cervix elongatio, and operation technique was also challenging.

Comparison of cervical length measured by POP-Q C-D and MRI: Why is POP-Q C-D not accurate?

OBJECTIVE

To investigate the relationship between the cervical length evaluated by Pelvic Organ Prolapse Quantification (POP-Q) point C minus D (C-D; ECL) and the magnetic resonance imaging (MRI)-based cervical length (MCL).

STUDY DESIGN

This was a retrospective study of patients with POP II-IV who underwent MRI. The ECL was calculated based on the absolute value of C-D according to POP-Q. The MCL was defined as the distance between the internal and external cervical os on MRI. Intraobserver reliability using the Bland-Altman method. Continuous variables were compared by paired 2-tailed t-tests. Multiple linear regression analysis was used to analyse the factors influencing differences between the ECL and MCL.

RESULTS

Among 105 eligible patients, 89 patients were eventually included in the study. The Bland-Altman scatter plots show that the intraobserver reliability of MCL was excellent. Furthermore, the mean ECL was significantly longer than the mean MCL (48.15 mm ± 27.46 vs. 28.25 mm ± 10.27, P = 0.000).Body mass index, parity, menopausal status or total vaginal length did not affect the difference between ECL and MCL. However, The larger the point Ba, the larger the difference between the ECL and MCL. The larger the point Bp, the smaller the difference between the ECL and MCL.

CONCLUSION

In general, POP-Q C-D was longer than the cervical length measured by MRI. Deep analysis found that when uterine prolapse is combined with larger anterior vaginal wall prolapse, the difference between ECL and MCL is greater; when uterine prolapse with larger posterior vaginal wall prolapse, the difference between ECL and MCL is smaller.

Defining Cervical Elongation: A Prospective Observational Study

OBJECTIVES

Our primary aim was to define cervical elongation (CE) using the following methods: (1) measurement of pathology specimen, (2) physician perception, (3) intraoperative estimate of anterior cervical length, and (4) office Pelvic Organ Prolapse Quantification (POP-Q) points C and D. Our secondary aim was to determine whether these definitions correlate with perioperative outcomes.

METHODS

Women undergoing vaginal hysterectomy and prolapse repair were enrolled. Office POP-Q measurements were collected. Estimates of cervical length were made based on points C minus D of the POP-Q and by manual exam using the surgeon's index and middle fingers. Cervical dimensions were measured from the pathology specimen at the end of the case. CE was defined as one standard deviation (SD) above the mean for each definition. Additional intraoperative data was collected to determine the surgeon perception of cervical anatomy.

RESULTS

A total of 90 patients were enrolled during the study period. Our definitions for CE were as follows: (1) 5 cm (70 without and 20 with CE), (2) physician perception (67 without and 23 with CE), (3) 3.4 cm (79 without and 11 with CE), and (4) 8.3 cm (77 without and 13 with CE). After controlling for uterine weight and the presence of fibroids, the operative time was the only outcome measure that remained elevated for patients with CE using our first definition (42.4 ± 20.1 without vs. 53.8 ± 19.2 with CE, P = 0.03).

CONCLUSIONS

CE using our first definition was associated with a statistically significant increase in operative time in women undergoing hysterectomy at the time of prolapse repair.

Differential gene expression of extracellular-matrix-related proteins in the vaginal apical compartment of women with pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Pelvic organ prolapse (POP) is a multifactorial disorder that impairs the quality of life (QoL) of older women in particular. The purpose of this study was to elucidate the pathogenesis of POP by focusing on the extracellular matrix (ECM).

METHODS

Patients were classified into two groups-with or without cervical elongation-using the POP quantification system. Specimens were obtained from 29 women with POP during hysterectomy. The expression of fibulin-5, elastin, integrin β1 (ITGβ1), lysyl oxidase-like protein-1 (LOXL1) and collagen in the vagina, uterosacral ligament, and uterine cervix was investigated by quantitative real-time polymerase chain reaction (RT-PCR) and correlation between gene levels and severity of POP examined. The location of proteins was analyzed using immunohistochemical staining and expression of fibulin-5 protein analyzed by Western blotting.

RESULTS

Fibulin-5 and elastin were mainly expressed in lamina propria and fibromuscular layers of the vagina and uterosacral ligament. Gene levels of fibulin-5 and ITGβ1 in uterosacral ligaments increased with severity of POP in women with cervical elongation, while no correlation was observed in women with a normal cervix. In women with uterine cervical elongation, each ECM-related gene significantly increased with POP staging. Furthermore, fibulin-5 protein also increased in the uterosacral ligament and uterine cervix.

CONCLUSIONS

The severity of POP and gene expression of ECM-related proteins were inversely correlated in vaginal tissue in a normal and elongated cervix. These results suggested that the differing progression of the two types of POP have a relationship with ECM-related protein.

Putting POP-Q to the test: does C - D = cervical length?

INTRODUCTION AND HYPOTHESIS

We investigated the correlation between calculated cervical length (CCL) and gross specimen cervical length (GCL) after total vaginal hysterectomy (TVH) at the time of surgery for pelvic organ prolapse (POP).

METHODS

This was a retrospective chart review of patients who had undergone TVH with reconstructive surgery for POP between 2013 and 2015. Patients without an intact specimen or documented cervical length in the pathology report were excluded. CCL was defined as the absolute difference between Pelvic Organ Prolapse Quantification (POP-Q) points C and D. GCL was obtained from the pathology report as the distance from the external to the internal os. The Bland-Altman method was used to assess the accuracy of POP-Q measurements with a priori ranges. Symptom severity was evaluated using the PFDI-20 questionnaire. Analysis of variance was used to model both GCL and CCL as a function of prolapse stage and the leading compartment.

RESULTS

The final analysis included 202 subjects. Of the CCL measurements, 56.93% were within ±2 cm of GCL, while 36.14% were within ±1 cm. POP stage was significantly associated with GCL (P < 0.0024). CCL was significantly longer in patients with stage 4 POP (3.57 cm, 95% CI 3.13-4.00) than in those with stage 2 POP (P < 0.0017; mean 2.68 cm, 95% CI 2.45-2.92) and stage 3 POP (P < 0.0300; mean 2.94 cm, 95% CI 2.73-3.15). There were no significant correlations between PFDI scores and CCL or GCL.

CONCLUSIONS

The agreement between POP-Q CCL (|C - D|) and GCL decreases with increasing POP-Q stage. There was no correlation between POP symptom severity and GCL or CCL. GCL significantly increased with increasing POP stage.

Distance From Cervicovaginal Junction to Anterior Peritoneal Reflection Measured During Vaginal Hysterectomy

OBJECTIVE

To quantify the distance of the dissection plane from the cervicovaginal junction to the anterior peritoneal reflection for vaginal hysterectomy.

METHODS

This is a descriptive study examining the dissection plane for anterior colpotomy in 22 surgical patients undergoing vaginal hysterectomy and in nine cadaver specimens. Intraoperatively, the distance from the vaginal incision to the anterior peritoneal reflection was measured on the uterus after removal. In nine of these patients, this distance was also measured before anterior peritoneal incision. Embalmed cadavers with intact pelvic viscera were dissected and the distance of the same dissection plane was measured.

RESULTS

Median (interquartile range) surgical patient age was 51.5 (42-63) years and the main surgical indications were abnormal uterine bleeding and pelvic organ prolapse. In these patients, the median (interquartile range) distance from cervicovaginal incision to anterior peritoneal reflection was 3.4 (2.6-3.7) cm. In cadavers, the median (interquartile range) age was 81 (72-86) years with a measured distance of 2.7 (2.4-2.9) cm.

CONCLUSION

When performing a vaginal hysterectomy, surgeons can expect a median (range) dissection distance of 3.4 (1.8-4.6) cm from initial incision to the peritoneal reflection for anterior colpotomy.

Study of Prolapse-Induced Cervical Elongation

OBJECTIVE

The cervix often appears to be elongated in women with pelvic organ prolapse (POP). This can pose surgical challenges. MRI evidence has suggested that prolapsed cervices are significantly longer than those in normal controls. Our objective was to compare cervical length in surgical hysterectomy specimens from women with symptomatic POP with the length in specimens from women with other benign gynaecological conditions.

METHODS

In this pilot, prospective, case-control study, hysterectomy specimens were collected at St. Paul's Hospital, Vancouver, BC, between 2013 and 2015. Recorded patient demographics were age at the time of hysterectomy, any prior history of cervical dysplasia, and reason for hysterectomy. Specimens from women in whom the indication for hysterectomy was POP were compared with the specimens from women with other benign gynaecological conditions. Specimens were excluded if there was a history of cervical dysplasia because we could not verify whether women had undergone previous procedures resulting in cervical shortening. After bivalving each uterus, cervical and total uterine lengths were measured by staff pathologists, and the ratios of cervical length to total uterine length were calculated. Measurements in the two hysterectomy groups were compared using linear regression.

RESULTS

Seventy-seven specimens were collected, 52 from women with POP and 25 from women without POP. The most common indication for hysterectomy in women without POP was uterine fibroids. Women with POP were on average older than women without POP (mean 58.5 years vs. 47.8 years, P < 0.001). The ratio of cervical length to total uterine length in women with POP was 0.10 higher (95% CI 0.03, 0.16; P = 0.005) than in women without POP.

CONCLUSION

Women with symptomatic POP have significantly higher ratios of cervical length to total uterine length than women without POP.

Systematic classification of uterine cervical elongation in patients with pelvic organ prolapse

OBJECTIVE

To define and classify cervical elongation, to compare uterine measurements after prolapse hysterectomy with a non-prolapse control group, and to associate stage of prolapse and degree of cervical elongation.

STUDY DESIGN

This was a single-centre retrospective case-control study conducted at the University Hospital, Urogynaecological Unit, with a certified urogynaecological surgeon. Data were collected from patients with and without pelvic organ prolapse (POP) who underwent laparoscopically assisted vaginal hysterectomy. Post-hysterectomy uterine cervical elongation was examined using the corpus/cervix ratio (CCR), calculated from measurements taken on photographs. Cervical elongation was classified as physiological (grade 0, CCR>1.5) grade I (CCR>1 and ≤1.5) grade II (CCR>0.5 and ≤1), and grade III (CCR≤0.5).

RESULTS

Cervical elongation was detected in 288/295 (97.6%) patients in the prolapse group (grade I, 44/288 [15.2%]; grade II, 212 [73.6%]; grade III, 32 [11.1%]). Mean CCR was greater among those with stage II/III than among those with stage IV prolapse (1.0±0.4 vs. 0.8±0.2; p<0.001). Grades of cervical elongation and prolapse stages were associated (p<0.001). Grade I cervical elongation was detected in 26/69 (37.6%), grade II in 5/69, and grade III in 0/69 patients of the control group. Cervical elongation was found more often in the prolapse group compared to the control group (p<0.001). Mean total uterine length did not differ between the prolapse and control groups (8.0±1.6 vs. 8.2±1.3cm), but mean calculated cervical length was greater in the prolapse group than in the control group (4.4±1.1 vs. 3.1+0.8cm; p<0.001).

CONCLUSIONS

Uterine cervical elongation is found in patients undergoing hysterectomy for pelvic organ prolapse. Cervical elongation grades and prolapse stages are correlated. Defining uterine cervical elongation based on corpus/cervix ratio with grades I-III could be a valuable basic tool for further research.

Pelvic Floor Support Defect in Apical Anterior Vaginal Prolapse with Cervical Hypertrophy. Review with Case Report in a 20-year-old Cadaver

Apical anterior vaginal wall prolapse (AVWP) with central defect is uncommon in young non hysterectomized patients causing considerable mortality after the fourth decade of life. Its high propensity to recurrence poses the greatest challenge to pelvic reconstructive surgeons. Approximately 40% of women with prolapse have hypertrophic cervical elongation and the extent of elongation increases with greater degrees of prolapse. Women with prolapse either have inherent hypertrophic elongation of the cervix which predisposes them to prolapse or the downward traction in prolapse leads to cervical elongation. The Pelvic Organ Prolapse Quantification (POP-Q) examination includes measurement of the location of the posterior fornix (point D) with the assumption that this measurement is associated with cervical elongation. Multifocal site involvement with apical and perineal descent primarily afflicts elderly, postmenopausal women after the fourth decade while cervical hypertrophic elongation with prolapse is observed in younger women less than 40 years of age. A review of the anatomical implication of the association of cervical hypertrophy in prolapse is carried out in this article. We observed a combination of distension type anterior vaginal prolapse with apical descent and cervical hypertrophy in a 20-year-old cadaver during routine dissection for undergraduate medical students at Sikkim Manipal Institute of Medical Sciences in 2013. Distension type anterior vaginal prolapse with central defect is rarer as most reported cases are of the displacement type, paravaginal defect. Hypertrophic cervical elongation is either the cause or consequence of prolapse and its identification before reconstructive surgery is paramount as uterine suspension in the face of cervical elongation is contraindicated. Inappropriate identification of all support defects and breaking of tissues is the primary cause of failure of laparoscopic pelvic reconstructive surgery.

Is cervical elongation associated with pelvic organ prolapse?

INTRODUCTION AND HYPOTHESIS

It is commonly believed that pelvic organ prolapse (POP) is associated with cervical elongation. However, cervical lengths have not been formally compared between women with prolapse and those with normal support.

METHODS

Cervix and uterine corpus lengths were measured on magnetic resonance images in a case-control study of 51 women with prolapse and 46 women with normal support determined by the Pelvic Organ Prolapse Quantification (POP-Q) examination. Group matching ensured similar demographics in both groups. Ranges for normal cervical lengths were determined from the values in the control group in order to evaluate for cervical elongation amongst women with prolapse.

RESULTS

The cervix is 36.4 % (8.6 mm) longer in women with prolapse than in women with normal pelvic support (p < 0.001). Linear regression modeling suggests the feature most highly associated with cervical length is the degree of uterine descent (POP-Q point C). Approximately 40 % of women with prolapse have cervical elongation; 57 % of cervical elongation in prolapse can be explained by a logistic regression-based model including POP-Q point C, body mass index, and menopausal status.

CONCLUSIONS

Cervical elongation is found in one third of women with POP, with the extent of elongation increasing with greater degrees of uterine descent.
