Short-term outcomes of laparoscopic ventral rectopexy for obstructed defecation in patients with overt pelvic structural abnormalities-a Chinese pilot study

Mesh-associated complications in minimally invasive ventral mesh rectopexy: a systematic review

BACKGROUND

Ventral mesh rectopexy (laparoscopic and robotic) is a common and well established treatment of rectal prolapse. Although described as safe and effective, complications, especially mesh-associated ones are often mentioned. Additionally, there is no consensus regarding the mesh type and fixation method as well as the materials used for this purpose. The aim of this systematic review was to identify the total amount of complications and of those the mesh-associated ones.

METHODS

Pubmed, Web of Science and Cochrane Central Register were screened for complications in general and in detail regarding the mesh(es) and a systematic review was performed.

RESULTS

Following qualitative evaluation, 40 studies were identified for further investigation. Across 6269 patients, complications were found in 9.2% (622 patients). Mesh-related complications were described in 1.4% (88 patients) of which 64.8% were erosions, 11.4% fistulas and 13.6% mesh releases. The complication rate according to the different materials were low with 1% in biological and synthetic meshes and 1.8% in not further described or mixed mesh type. Non-absorbable material to fixate the mesh was most frequently used to fixate the mesh.

CONCLUSION

Laparoscopic ventral mesh rectopexy is a safe operation with a low-complication rate, regardless of mesh type.

Rectocele: victim of availability bias? Results of a Belgian survey of colorectal and gynecological surgeons

INTRODUCTION AND HYPOTHESIS

Women with a symptomatic rectocele may undergo different trajectories depending on the specialty consulted. This survey aims to evaluate potential differences between colorectal surgeons and gynecologists concerning the management of a rectocele.

METHODS

A web-based survey was sent to abdominal surgeons (CS group) and gynecologists (G group) asking about their perceived definition, diagnostic workup, multidisciplinary discussion (MDT) and surgical treatment of rectoceles. The answers of both groups were analyzed with the chi-square test or Fisher's exact test at p < 0.050.

RESULTS

A rectocele was defined as a prolapse of the posterior vaginal wall by 78% of the G and 41% of the CS group. All gynecologists and 49% of the CS group evaluated a rectocele clinically in dorsal decubitus, with 91% of gynecologists using a speculum and 65% using the Pelvic Organ Prolapse-Quantification (POP-Q) scoring system, compared to < 1/3 of colorectal surgeons. A digital rectal examination was performed by 90% of the CS group and 57% of the G group. A transvaginal ultrasound was only used by the G group, while anal manometry was opted for by the CS group (65%) and minimally by the G group (14%). In the G group, a posterior repair was the preferred surgical technique (78%), whereas 63% of the CS group preferred a rectopexy. Multidisciplinary discussions (MDT) were mostly organized ad hoc.

CONCLUSIONS

An availability bias is seen in different aspects of rectocele evaluation and treatment. Colorectal surgeons and gynecologists are acting based on their training and experience. Motivation for pelvic floor MDT starts with creating awareness of the availability bias.

A quantitative study to explore functional outcomes following laparoscopic ventral mesh rectopexy for rectal prolapse

INTRODUCTION

Rectal prolapse is a life-altering problem and laparoscopic ventral mesh rectopexy (LVMR) is emerging as the surgical intervention of choice. However, the literature is ambiguous on its effect on bowel function and sparse as regards bladder and sexual function. This study assesses short-term functional outcomes following LVMR.

MATERIALS AND METHODS

This quantitative retrospective study with a pretest-post-test design included 130 adults who had undergone LVMR from October 2010 to December 2018 in a tertiary centre. Analysis with paired-samples t-test and Wilcoxon matched pairs test was done using SPSS (v26).

RESULTS

The median age was 58 years (interquartile range, 48-74 years); 123 (94.6%) were female. The median length of stay was two days (interquartile range, 1-2 days). A total of 104 (80%) sets of medical notes were reviewed. One patient had recurrence of rectal prolapse. Synthetic mesh was used in 24 patients (23.1%) and biological mesh in 80 (76.9%). One patient had extrusion of a synthetic mesh and required surgery; 31(23.8%) completed the Electronic Patient Assessment Questionnaire for Pelvic Floor. Overall, the improvement in bladder function was not statistically significant (p = 0.670). A statistically significant improvement was seen for all bowel symptoms (p = 0.002) excluding constipation (p = 0.295). Irritable bowel symptoms associated with rectal prolapse improved significantly following LVMR (p = 0.001). Vaginal prolapse (p < 0.0005), dyspareunia (p = 0.001) and bowel symptoms affecting sexual intercourse (p = 0.01) improved, but improvement in overall sexual function was not statistically significant (p = 0.081).

CONCLUSIONS

LVMR improves bowel function overall, although it can worsen constipation. It has the potential to improve sexual function but makes negligible difference to bladder function.

Short term outcome of laparoscopic ventral mesh rectopexy for rectal and complex pelvic organ prolapse: case series

Objectives

Laparoscopic ventral mesh rectopexy (LVMR) is a technique gaining more recognition for the management of pelvic floor disorders, such as external rectal prolapse (ERP), high grade internal rectal prolapse (IRP) and rectocele. LVMR also allows correction of coexisted pelvic organ prolapse. This study aimed to evaluate the safety, efficacy and functional outcome of LVMR for rectal and complex pelvic organ prolapse.

Material and Methods

All patients who underwent LVMR from February 2014 to October 2017 were included into the study. The patients were evaluated preoperatively and three months postoperatively. Surgical complications and functional results in terms of fecal incontinence (measured with the Wexner Incontinence Score= WIS) and constipation (measured with the Wexner Constipation Score= WCS) were analyzed.

Results

Thirty (4 males) patients underwent LVMR. Seventeen (56.6%) patients had complex pelvic organ prolapse according to MRI findings. Median operative time and postoperative stay were 110 minutes and 4 days, respectively. No mesh-related complication and recurrence were observed. Before surgery, 21 (70%) patients had complained about symptoms of obstructed defecation. WCS decreased significantly from median 19 to 6 (p <0.001). Preoperative median WIS of 9 patients was 14 and went down to 6 postoperatively (p= 0.008). WCS significantly improved after LVMR in patients with symptomatic rectocele combined with enterocele or sigmoidocele (p= 0.005), and significant improvement was also observed in patients with symptomatic rectocele combined with gynecologic organ prolapse, preoperative median WCS was 18 and the postoperative value fell to 8 (p= 0.005).

Conclusion

LVMR is an effective surgical option for rectal and complex pelvic organ prolapse with short-term follow-up.

Laparoscopic Ventral Rectopexy Versus Stapled Transanal Rectal Resection for Treatment of Obstructed Defecation in the Elderly: Long-term Results of a Prospective Randomized Study

BACKGROUND

Obstructed defecation is a common complaint in coloproctology. Many anal, abdominal, and laparoscopic procedures are adopted to correct the underlying condition.

OBJECTIVE

The purpose of this study was to compare long-term functional outcome, recurrence rate, and quality of life between laparoscopic ventral rectopexy and stapled transanal rectal resection in the treatment of obstructed defecation.

DESIGN

This was a prospective randomized study.

SETTING

This study was performed at academic medical centers.

PATIENTS

Patients were included if they had obstructed defecation attributed to pelvic structural abnormalities that did not to respond to conservative measures. Exclusion criteria included nonrelaxing puborectalis, previous abdominal surgery, other anal pathology, and pudendal neuropathy.

INTERVENTION

Patients were randomly allocated to either laparoscopic ventral rectopexy (group 1) or stapled transanal rectal resection (group 2).

MAIN OUTCOME MEASURES

The primary outcome measures were improvement of modified obstructed defecation score and recurrences after ≥3 years of follow-up. Secondary outcomes were postoperative complications, continence status using Wexner incontinence score, and quality of life using Patient Assessment of Constipation-Quality of Life Questionnaire.

RESULTS

The study included 112 patients (56 in each arm). ASA score II was reported in 32 patients (18 in group 1 and 14 in group 2; p = 0.12), whereas 3 patients in each group had ASA score III. Minor postoperative complications were seen in 11 patients (20%) of group 1 and 14 patients of group 2 (25%; p = 0.65). During follow-up, 3 patients had fecal urgency after stapled transanal rectal resection but no sexual dysfunction in either procedure. After 6 months, modified obstructed defecation score improvement >50% was reported in 73% versus 82% in groups 1 and 2 (p = 0.36). After a mean follow-up of 41 months, recurrences of symptoms were reported in 7% in group 1 versus 24% in group 2 (p = 0.04). Six months postoperation, perineal descent improved >50% in defecogram in 80% of group 1 versus no improvement in group 2. Quality of life significantly improved in both groups after 6 months; however a significant long-term drop (>36 months) was seen only in group 2.

LIMITATIONS

Possible limitations of this study are the presence of a single operator and the absence of blindness of the technique for both patient and assessor.

CONCLUSIONS

In elderly patients even with comorbidities, both laparoscopic ventral rectopexy and stapled transanal rectal resection are safe and can improve function of the anorectum in patients with obstructed defecation attributed to structural abnormalities. Laparoscopic ventral rectopexy has better long-term functional outcome, less complications, and less recurrences compared with stapled transanal rectal resection. Perineal descent only improves after laparoscopic ventral rectopexy. Stapled transanal rectal resection was shown not to be the first choice in elderly patients with obstructed defecation unless they had a medical contraindication to laparoscopic procedures.
