Introducing an innovative surgical technique: gluteal turnover flap for posterior vaginal wall reconstruction: a case series

Four patients with rectal cancer required reconstruction of a defect of the posterior vaginal wall. All patients received neoadjuvant (chemo)radiotherapy, followed by an en bloc (abdomino)perineal resection of the rectum and posterior vaginal wall. The extent of the vaginal defect necessitated closure using a tissue flap with skin island. The gluteal turnover flap was used for this purpose as an alternative to conventional more invasive myocutaneous flaps (gracilis, gluteus, or rectus abdominis). The gluteal turnover flap was created through a curved incision at a maximum width of 2.5 cm from the edge of the perineal wound, thereby creating a half-moon shape skin island. The subcutaneous fat was dissected toward the gluteal muscle, and the gluteal fascia was incised. Thereafter, the flap was rotated into the defect and the skin island was sutured into the vaginal wall defect. The contralateral subcutaneous fat was mobilized for perineal closure in the midline, after which no donor site was visible.The duration of surgery varied from 77 to 392 min, and the hospital stay ranged between 3 and 16 days. A perineal wound dehiscence occurred in two patients, requiring an additional VY gluteal plasty in one patient. Complete vaginal and perineal wound healing was achieved in all patients. The gluteal turnover flap is a promising least invasive technique to reconstruct posterior vaginal wall defects after abdominoperineal resection for rectal cancer.

Aim: to qualitatively improve the approach to timely detection of purulent septic compli-cations in pregnant women with a long anhydrous interval in the setting of prelabour rupture of membranes (PROM). Patients and Methods: this prospective single-center study involved 80 pregnant women at 32–34 weeks of gestation. Group 1 included 40 pregnant women with PROM and group 2 included 40 pregnant women with threatened preterm labor. Serum levels of presepsin (PSP), leukocyte count, and C-reactive protein (CRP) were measured at admission and after 24 and 48 hours. A somatic, gynecological, and obstetric history was also studied Results: pregnant women with PROM exhibited an aggravated somatic, gynecological, and obstetric history, which could be a prerequisite for purulent septic complications. Elevated PSP levels (≥300 pg/mL) were observed in 23 (57.5%) women in group 1 and 2 (5%) women in group 2. Chorioamnionitis developed in 7 (17.5%) women in group 1 with PSP levels ≥500 pg/mL and two or more clinical signs. Leukocytosis and elevated CRP were detected in 3 (7.5%) and 5 (21.7%) women, respectively. No cases of postpartum endometritis were reported. Mean-while, in group 1, partial abdominal wound dehiscence after C-section was found in 4 of 11 (36.4%) women and partial perineal wound dehiscence was found in 2 of 40 (5%) women. All complications were observed in women with high PSP at admission. No complications were de-tected in group 2. Conclusion: elevated PSP can be considered as a predictor for purulent septic complica-tions in women with PROM. This marker can be used as an additional criterion for revising treatment and choosing term and mode of delivery. PSP level reflects early manifestations of pu-rulent septic complications more quickly than CRP level and leukocyte count.

A comparison of surgical techniques for perineal wound closure following perineal excision: a systematic review and network meta-analysis.

To mitigate pelvic wound issues following perineal excision of rectal or anal cancer, a number of techniques have been suggested as an alternative to primary closure. These methods include the use of a biological/dual mesh, omentoplasty, muscle flap, and/or pelvic peritoneum closure. The aim of this network analysis was to compare all the available surgical techniques used in the attempt tomitigate issues associated with an empty pelvis. An electronic systematic search using MEDLINE databases (PubMed), EMBASE, and Web of Science was performed (Last date of research was March 15th, 2023). Studies comparing at least two of the aforementioned surgical techniques for perineal wound reconstruction during abdominoperineal resection, pelvic exenteration, or extra levator abdominoperineal excision were included. The incidence of primary healing, complication, and/or reintervention for perineal wound were evaluated. In addition, the overall incidence of perineal hernia was assessed. Forty-five observational studies and five randomized controlled trials were eligible for inclusion reporting on 146,398 patients. All the surgical techniques had a comparable risk ratio (RR) in terms of primary outcomes. The pooled network analysis showed a lower RR for perineal wound infection when comparing primary closure (RR 0.53; Crl 0.33, 0.89) to muscle flap. The perineal wound dehiscence RR was lower when comparing both omentoplasty (RR 0.59; Crl 0.38, 0.95) and primary closure (RR 0.58; Crl 0.46, 0.77) to muscle flap. Surgical options for perineal wound closure have evolved significantly over the last few decades. There remains no clear consensus on the "best" option, and tailoring to the individual remains a critical factor.

Perineal resuturing versus conservative treatment for dehisced perineal wounds and episiotomies: a systematic review and meta-analysis.

Perineal wound dehiscence is associated with complications, such as infections, perineal pain, dyspareunia, and altered sexual function, that severely affects women's health. Currently, few studies have examined secondary repair of first- and second-degree perineal wound dehiscence and episiotomies, and there is currently no consensus on the optimal treatment option for dehisced perineal wounds. The objective was to evaluate whether resuturing or conservative treatment of first- and second-degree dehisced perineal wounds and episiotomies is the optimal treatment modality in terms of postoperative healing time and other secondary outcomes. A systematic literature search was carried out using PubMed, Embase, and Cochrane databases. All included studies were evaluated using the SIGN methodology checklist, with the purpose of assessing the study quality. Three randomized controlled trials were included. Only two small sample-sized studies presented data regarding healing time for both the resuturing and the conservative treatment groups. However, no significant difference was found between the two groups at 4-6 weeks' healing time (RR 1.16, 95% CI 0.53-2.52). One study found that women being resutured experienced a significantly reduced healing time and higher satisfaction with the appearance of the wound healing at 3 months compared with the conservative treatment group. We found no significant differences in the healing time between the resuturing group and the conservative treatment group. However, the sample sizes of the studies were small. A well-designed, large, and prospective randomized controlled trial is needed to evaluate the optimal treatment modality for dehisced perineal wounds.

Effect of differing flap reconstruction strategies in perineal closure following advanced pelvic oncological resection: a retrospective cohort study.

Advancing approaches to locally invasive pelvic malignancy creates a large tissue defect resulting in perineal wound complications, dehiscence, and perineal hernia. Use of reconstructive flaps such as vertical rectus abdominus myocutaneous (VRAM) flap, gracilis, anterolateral thigh and gluteal flaps have been utilised in our institution to address perineal closure. The authors compared outcomes using different flap techniques along with primary perineal closure in advanced pelvic oncological resection. A prospectively maintained database of patients undergoing advanced pelvic oncological resection in a single tertiary hospital was retrospectively analysed. This study included consecutive patients between 2014 and 2021 according to the Strengthening The Reporting of Cohort Studies in Surgery (STROCSS) criteria. Primary outcome measures were the frequency of postoperative perineal complications between primary closure, VRAM, gluteal and thigh (anterolateral thigh and gracilis) reconstruction. One hundred twenty-two patients underwent advanced pelvic resection with perineal closure. Of these, 40 patients underwent extra-levator abdominoperineal resection, and 70 patients underwent pelvic exenteration. Sixty-four patients received reconstructive flap closure, which included VRAM (22), gluteal (21) and thigh flaps (19). Perineal infection and dehiscence rates were low. Infection rates were lower in the flap group despite a higher rate of radiotherapy ( P <0.050). Reoperation rates were infrequent (<10%) but specific for each flap, such as donor-site hernia following VRAM and flap dehiscence after thigh flap reconstruction. In patients who are at high risk of postoperative perineal infections, reconstructive flap closure offers acceptable outcomes. VRAM, gluteal and thigh flaps offer comparable outcomes and can be tailored to the individual patient.

Biosynthetic Mesh Reconstruction after Abdominoperineal Resection for Low Rectal Cancer: Cross Relation of Surgical Healing and Oncological Outcomes: A Multicentric Observational Study.

Local wound complications are among the most relevant sequelae after an abdominoperineal resection (APR) for low rectal cancer. One of the proposed techniques to improve the postoperative recovery and to accelerate the initiation of adjuvant chemotherapy is the mesh reinforcement of the perineal wound. The aim of the current study is to compare the surgical and oncological outcomes after APR performed with a biosynthetic mesh reconstruction versus the conventional procedure. From 2015 to 2020, in two tertiary centres, the surgical outcomes, the wound events (i.e., surgical site infections, wound dehiscence and the complete healing time) and the oncological outcomes (i.e., time length to start adjuvant chemo-radiotherapy, an over 8-week delay in chemotherapy and the recurrence rate) were retrospectively analysed in patients undergoing APR reinforced with biosynthetic mesh (Group A) and conventional APR (Group B). Results Sixty-one patients were treated with APR (25 in Group A and 36 in Group B). Patients in Group A presented lower time for: healing (16 versus 24 days, p = 0.015), inferior perineal wound dehiscence rates (one versus nine cases, p = 0.033), an earlier adjuvant therapy start (26 versus 70 days, p = 0.003) and a lower recurrence rate (16.6% vs. 33.3%, p = 0.152). In our series, the use of a biosynthetic mesh for the neo-perineum reconstruction after a Miles' procedure has resulted in safe, reproducible results affected by limited complications, guarantying a rapid start of the adjuvant therapy with clear benefits in oncological outcomes. Further randomized clinical trials with long-term follow-up are needed to validate these results.

The Skin Antiseptic agents at Vaginal dElivery (SAVE) trial: study protocol for a randomized controlled trial

BackgroundCleansing of the vulva and perineum is recommended during preparation for vaginal delivery, and special attention is paid to cleansing before episiotomy because episiotomy is known to increase the risk of perineal wound infection and/or dehiscence. However, the optimal method of perineal cleansing has not been established, including the choice of antiseptic agent. To address this issue, we designed a randomized controlled trial to examine whether skin preparation with chlorhexidine-alcohol is superior to povidone-iodine for the prevention of perineal wound infection after vaginal delivery.MethodsIn this multicenter randomized controlled trial, term pregnant women who plan to deliver vaginally after episiotomy will be enrolled. The participants will be randomly assigned to use antiseptic agents for perineal cleansing (povidone-iodine or chlorhexidine-alcohol). The primary outcome is superficial or deep perineal wound infection within 30 days after vaginal delivery. The secondary outcomes are the length of hospital stay, physician office visits, or hospital readmission for infection-related complications, endometritis, skin irritations, and allergic reactions.DiscussionThis study will be the first randomized controlled trial aiming to determine the optimal antiseptic agent for the prevention of perineal wound infections after vaginal delivery.Trial registrationClinicalTrials.gov NCT05122169.

PERINEOTOMY CARE AFTER CHILDBIRTH

Every woman who became pregnant has to undergo the process of delivery. In normal process of delivery the baby is delivered per vagina, an episiotomy is performed by health care provider or midwife. Episiotomy is a surgically planned incision on the perineum and the posterior vaginal wall during the second stage of labour to enlarge the vaginal introits so as to facilitate easy and safe delivery of the fetus. Episiotomy may be advice in the situations such as inelastic perineum, fetal distress, and complicated birth, prolonged second stage of labor, instrumental vaginal delivery and previous perineal surgeries .There are four types of episiotomy: midline, mediolateral, lateral and J shaped. Care of episiotomy involves perineal care, sitz bath, infrared heat, perineal exercises, antiseptic ointments, cold and hot packs The REEDA scale is used for assessing the perineal healing. Complications of episiotomy include perineal discomfort, perineal pain, difculty with breast feeding and walking, perineal bleeding, infection, wound dehiscence and dyspareunia.

The clinical progression and wound healing rate of dehisced perineal tears healing by secondary intention: A prospective observational study

ObjectivesTo establish the clinical progression of dehisced perineal wounds healing by secondary intention and to investigate the incidence and factors associated with delayed healing. MethodsSecondary analysis of women with perineal wound dehiscence recruited into the PERINEAL study between August 2020- August 2021 (NCT 04480684). Three-dimensional wound measurements were taken with the Silhouette® camera. Significant bacterial colonisation was diagnosed using the MolecuLight i:X camera. As it is agreed that acute wounds should heal sufficiently within four weeks, diagnosis of delayed wound healing was made if a wound took longer than four weeks to heal. A wound was deemed to have healed if there was complete wound closure, with no evidence of granulation tissue or signs of infection on clinical examination. Results55 women with perineal wound dehiscence participated. Wounds took an average of 3 weeks to heal (range 1–16) and 38 (69.1%) wounds healed in ≤ 4 weeks from the first clinical review. 17 (30.9%) wounds had significant bacterial colonisation, identified on bacterial fluorescence imaging.Women with a wound area of < 1.60 cm2 or wound perimeter of < 5.57 cm had a 70% probability of wound healing in ≤ 4 weeks. 47.1% of wounds with significant bacteria colonisation healed within 4 weeks, in comparison to 78.9% of wounds not colonised (p = 0.03). 25.0 % (n = 2) of wounds with OASI healed within 4 weeks, in comparison to 76.5% (n = 36) of wounds with no OASI (p = 0.02). Bacterial fluorescence (OR 0.21 (0.05–0.87)) and OASIs (OR 0.09 (0.01–0.66)) were independent risk factors associated with delayed wound healing. The model including wound area, fluorescence and OASIs had the greatest AUC (0.81, 95% CI 0.67–0.94) indicating the best predictive model. ConclusionsThis is the first study to describe healing outcomes of dehisced perineal wounds and factors associated with delayed healing. The study findings will help clinicians counsel women effectively and tailor follow-up care at the first assessment, based on individual risk factors.

Biological mesh versus primary closure for pelvic floor reconstruction following extralevator abdominoperineal excision: a meta-analysis

Objective: To compare the morbidity of perineum-related complication between biological mesh and primary closure in closing pelvic floor defects following extralevator abdominoperineal excision (ELAPE). Methods: A literature search was performed in PubMed, Embase, Cochrane Library, Web of Science, Wanfang database, Chinese National Knowledge Infrastructure, VIP database, and China Biological Medicine database for published clinical researches on perineum-related complications following ELAPE between January 2007 and August 2020. Literature inclusion criteria: (1) study subjects: patients undergoing ELAPE with rectal cancers confirmed by colonoscopy pathological biopsy or surgical pathology; (2) study types: randomized controlled studies or observational studies comparing the postoperative perineum-related complications between the two groups (primary perineal closure and reconstruction with a biological mesh) following ELAPE; (3) intervention measures: biological mesh reconstruction used as the treatment group, and primary closure used as the control group; (4) outcome measures: the included literatures should at least include one of the following postoperative perineal complications: overall perineal wound complications, perineal wound infection, perineal wound dehiscence, perineal hernia, chronic sinus, chronic perineal pain (postoperative 12-month), urinary dysfunction and sexual dysfunction. Literature exclusion criteria: (1) data published repeatedly; (2) study with incomplete or wrong original data and unable to obtain original data. Two reviewers independently performed screening, data extraction and assessment on the quality of included studies. Review Manager 5.3 software was used for meta-analysis. The mobidities of perineum-related complications, including overall perineal wound (infection, dehiscence, hernia, chronic sinus) and perineal chronic pain (postoperative 12-month), were compared between the two pelvic floor reconstruction methods. Finally, publication bias was assessed, and sensitivity analysis was used to evaluate the stability of the results. Results: A total of five studies, including two randomized controlled studies and three observational controlled studies, with 650 patients (399 cases in the biological mesh group and 251 cases in primary closure group) were finally included. Compared with primary closure, biological mesh reconstruction had significantly lower ratio of perineal hernia (RR=0.37, 95%CI: 0.21-0.64, P<0.001). No significant differences in ratios of overall perineal wound complication, perineal wound infection, perineal wound dehiscence, perineal chronic sinus and perineal chronic pain (postoperative 12-month) were found between the two groups (all P>0.05). Conclusion: Compared with primary closure, pelvic floor reconstruction following ELAPE with biological mesh has the advantage of a lower incidence of perineal hernia.

Empty pelvis syndrome: a systematic review of reconstruction techniques and their associated complications.

Empty pelvis syndrome is a major contributor to morbidity following pelvic exenteration. Several techniques for filling the pelvis have been proposed; however, there is no consensus on the best approach. We evaluated and compared the complications associated with each reconstruction technique with the aim of determining which is associated with the lowest incidence of complications related to the empty pelvis. The systematic review protocol was prospectively registered with PROSPERO (CRD42021239307). PRISMA-P guidelines were used to present the literature. PubMed and MEDLINE were systematically searched up to 1 February 2021. A dataset containing predetermined primary and secondary outcomes was extracted. Eighteen studies fulfilled our criteria; these included 375 patients with mainly rectal and gynaecological cancer. Only three studies had a follow-up greater than 2years. Six surgical interventions were identified. Mesh reconstruction and breast prosthesis were associated with low rates of small bowel obstruction (SBO), entero-cutaneous fistulas and perineal hernia. Findings for myocutaneous flaps were similar; however, they were associated with high rates of perineal wound complications. Omentoplasty was found to have a high perineal wound infection rate (40%). Obstetric balloons were found to have the highest rates of perineal wound dehiscence and SBO. Silicone expanders effectively kept small bowel out of the pelvis, although rates of pelvic collections remained high (20%). The morbidity associated with an empty pelvis remains considerable. Given the low quality of the evidence with small patient numbers, strong conclusions in favour of a certain technique and comparison of these interventions remains challenging.

Perineal reconstruction after extralevator abdominoperineal resection: Differences among minimally invasive, open, or open with a vertical rectus abdominis myocutaneous flap approaches

BackgroundPerineal wound complications after extralevator abdominoperineal resection for cancer are common with no consensus on optimal reconstructive technique. We compared short- and long-term results of laparoscopic abdominoperineal resection with open surgery ± vertical rectus abdominis myocutaneous flap. MethodsThis is a single-institution retrospective observational study of 204 consecutive patients with advanced low rectal cancer who underwent extralevator abdominoperineal resection from January 2010 to August 2020. Main outcome measures were short-term results, wound complications, and incisional, parastomal, and perineal hernia rates. ResultsFifty-five (27%) patients had a laparoscopic approach, 80 (39%) open, and 69 (33%) open + vertical rectus abdominis myocutaneous flap. The groups had similar median length of follow up (P = .75). Patients’ age and radiation, intraoperative and postoperative complications, mortality, and readmission rates were similar among the 3 groups. Perineal wound infection and dehiscence rates were not influenced by surgical approach. Laparoscopy resulted in higher perineal (7.3 vs 2.5 vs 0%; P = .047) and parastomal (23.6 vs 13.8 vs 5.8%; P = .016) hernia rates than did open or open + vertical rectus abdominis myocutaneous flap. Patients who underwent an open approach had a higher body mass index and rate of prior surgeries and preoperative ostomies. Laparoscopic and open approaches had significantly shorter operative times (300 vs 303 vs 404 minutes, respectively; P < .001) and shorter length of stay (7.6 vs 10.8 vs 11.12, respectively; P = .006) compared to open with a flap approach. ConclusionOpen and open + vertical rectus abdominis myocutaneous flap approaches for reconstruction after abdominoperineal resection had lower parastomal and perineal hernias rates but similar postoperative morbidity as did the laparoscopic approach.

The combined use of pedicled profunda artery perforator and bilateral gracilis flaps for pelvic reconstruction: A cohort study

The result of an extra-levator abdominoperineal excisionof the rectum (ELAPE) is a composite three-dimensional defect. This is performed for locally advanced anorectal cancer, and may involve partial excision of the vagina. The aim of reconstruction is to achieve wound healing, restore the pelvic floor and to allow micturition and sexual function. We aim to evaluate the concurrent use of profunda artery perforator (PAP) and bilateral gracilis flaps for vaginal and pelvic floor reconstruction. We performed a retrospective case note review of patients undergoing pelvo-perineal reconstruction with combined gracilis and PAP flaps between July 2018 and December 2019. Eighteen pedicled flaps were performed on six patients with anal or vulval malignancies. All underwent pre-operative radiotherapy. Four patients had extended abdominoperineal tumour resections, while two patients underwent total pelvic exenteration. The median age was 57 (range 47-74) years, inpatient stay was 22 (11-47) days and the follow-up was 10 (5-21) months. Four patients developed partial perineal wound dehiscence, of which one was re-sutured. One patient had a post-operative bleed requiring radiological embolisation of an internal iliac branch and had subsequent 1cm PAP flap loss. All other flaps survived completely. Median time to heal was 4 (1-6) months. This is the first series reporting combined bilateral gracilis and PAP flaps for pelvic reconstruction. The wound dehiscence rate and healing times were expected in the context of irradiation and radical pelvic tumour resection. This is a reliable technique for perineal and vaginal reconstruction with minimal donor site morbidity.

Comparison of perineal morbidity between biologic mesh reconstruction and primary closure following extralevator abdominoperineal excision: a systematic review and meta-analysis.

Extralevator abdominoperineal excision (ELAPE) for rectal cancer leaves a greater perineal defect which might result in significant perineal morbidity, and how to effectively close perineal defects remains a challenge for surgeons. This study aimed to comparatively evaluate the perineal-related complications of biologic mesh reconstruction and primary closure following ELAPE. The electronic databases PubMed, EMBASE, Cochrane Library, and Web of Science were searched to screen out all eligible studies, which compared biologic mesh reconstruction with primary closure for perineal-related complications following ELAPE. Pooled data of perineal-related complications including overall wound complications, hernia, infection, dehiscence, chronic sinus, and chronic pain (12 months after surgery) were analyzed. A total of four studies (one randomized controlled trial and three cohort studies) involving 544 patients (346 biologic mesh vs 198 primary closure) were included. With a median follow-up of 18.5 months (range, 2-71.5 months). Analysis of the pooled data indicated that the perineal hernia rate was significantly lower in biologic mesh reconstruction as compared to primary closure (OR, 0.38; 95% CI, 0.22-0.69; P = 0.001). There were no statistically significant differences between the two groups in terms of total perineal wound complications rate (P = 0.70), as well as rates of perineal wound infection (P = 0.97), wound dehiscence (P = 0.43), chronic sinus (P = 0.28), and chronic pain (12 months after surgery; P = 0.75). Biologic mesh reconstruction after extralevator abdominoperineal excision appears to have a lower hernia rate, with no differences in perineal wound complications.

Early re-suturing of dehisced obstetric perineal wounds: A 13-year experience

ObjectivesTo describe post-operative outcomes following early re-suturing of obstetric perineal wound dehiscence. Study DesignThis was a retrospective series of 72 women who underwent re- suturing of a dehisced perineal wound at a tertiary urogynaecology department during a 13-year period (December 2006 - December 2019). ResultsSeventy-two women with complete perineal wound dehiscence opted for secondary re-suturing. Other accompanying symptoms included purulent discharge from the wound (22.2 %), perineal pain (23.6 %) and both purulent discharge and pain (26.4 %). The median time taken for the wound to heal completely following re-suturing was 28 days (IQR 14.0-52.0); 49.2 % had healed completely by four weeks, 63.5 % by six weeks and 76.2 % by eight weeks. The median number of out-patient follow-up appointments required was 2 (IQR 1.0-3.0). No post-operative complications were experienced in 63.6 % of women, one complication occurred in 25.8 % and two complications in 10.6 %. Complications included skin dehiscence (33.3 %), granuloma (33.3 %), scar tissue (17.6 %), perineal pain (5.9 %) and sinus formation (5.9 %). Of the women who developed two complications, four developed skin dehiscence with granulation tissue and one had skin sinus formation. One developed granulation tissue with perineal pain. All complications were managed conservatively in an outpatient setting or surgically under local anaesthetic, without further complication. There was no significant difference (p = 0.443) in complication rates between the group (n = 10) with dehisced wounds with signs of wound infection (purulent discharge or the presence of both purulent discharge and pain) pre-operatively versus the group (n = 14) without signs of infection. ConclusionsThis study demonstrates the positive outcomes of early re-suturing of perineal wound dehiscence with faster healing, reduced follow-up requirements and few major complications. It provides information to clinicians who are uncertain about the effects of early re-suturing of perineal wounds which can be used to help counsel mothers with wound dehiscence on their management options.

Transperineal minimally invasive APE: preliminary outcomes in a multicenter cohort

BackgroundAbdominoperineal excision (APE) for rectal cancer is associated with a relatively high risk of positive margins and postoperative morbidity, particularly related to perineal wound healing problems. It is unknown whether the use of a minimally invasive approach for the perineal part of these procedures can improve postoperative outcomes without oncological compromise. The aim of this study was to evaluate the feasibility of minimally invasive transperineal abdominoperineal excision (TpAPE)MethodsThis multicenter retrospective cohort study included all patients having TpAPE for primary low rectal cancer. The primary endpoint was the intraoperative complication rate. Secondary endpoints included major morbidity (Clavien–Dindo ≥ 3), histopathology results, and perineal wound healing.ResultsA total of 32 TpAPE procedures were performed in five centers. A bilateral extralevator APE (ELAPE) was performed in 17 patients (53%), a unilateral ELAPE in 7 (22%), and an APE in 8 (25%). Intraoperative complications occurred in five cases (16%) and severe postoperative morbidity in three cases (9%). There were no perioperative deaths. A positive margin (R1) was observed in four patients (13%) and specimen perforation occurred in two (6%). The unilateral extralevator TpAPE group had worse specimen quality and a higher proportion of R1 resections than the bilateral ELAPE or standard APE groups. The rate of uncomplicated perineal wound healing was 53% (n = 17) and three patients (9%) required surgical reintervention.ConclusionsTpAPE seems to be feasible with acceptable perioperative morbidity and a relatively low rate of perineal wound dehiscence, while histopathological outcomes remain suboptimal. Additional evaluation of the viability of this technique is needed in the form of a prospective trial with standardization of the procedure, indication, audit of outcomes and performed by surgeons with vast experience in transanal total mesorectal excision.

Still No Substantial Evidence to Use Prophylactic Antibiotic at Operative Vaginal Delivery: Systematic Review and Meta-Analysis.

Background Postpartum maternal infection is still a common problem worldwide, mainly due to obstetric risk factors. The use of prophylactic antibiotic at operative vaginal delivery (OVD), taking it as a standalone risk factor, has been controversial. The purpose of this review was to rigorously evaluate the association of OVD with postpartum infection and shed light on such highly controversial issue. Methods A computer-based literature search was done mainly in the databases of PUBMED, HINARI health research, and the Cochrane library. Systematic review and meta-analysis were done by including 14 articles published between 1990 and August 2019. Results The average absolute risk of postpartum infection at OVD from seven large cohort studies was 1%. Few studies showed a weak association of OVD with postpartum infection without being adjusted to perineal wound, but the pooled meta-analysis showed statistically significant association with non-OVD. In the included randomized trial, 97% of the study participants had perineal wound for whom repairs were performed; the risks of maternal infection and perineal wound breakdown were comparable, and maternal infections other than perineal wound infection did not show significant difference between prophylactic antibiotic and placebo groups. The majority of included studies demonstrated a strong association of postpartum infection and perineal wound dehiscence with episiotomy and perineal tear. Conclusion Both the relative and absolute risks of postpartum infection at OVD are extremely low unless accompanied by episiotomy and 3rd/4tht degree perineal tear. From previous studies, there is no substantial evidence to use prophylactic antibiotic at OVD, but episiotomy and perineal tear.

Perineal Wound Outcomes after Extralevator Abdominoperineal Excision for Rectal Adenocarcinoma- A Tertiary Care Centre Experience

Abstract Extralevator Abdominoperineal excision (ELAPE) for low rectal cancer results in a large perineal defect, often requiring reconstruction by a biological or absorbable mesh or a flap as compared to conventional Abdominoperineal excision (CAPE). Although there are indications for oncological superiority with ELAPE, the incidence of wound-related complications is postulated to be higher when compared to CAPE due to the removal of more amount of tissue around the anorectum. On the other hand, the incidence of inadvertent rectal tube perforation during dissection is lesser in ELAPE and hence perineal wound breakdown and infection are postulated to be lesser in some other studies. We conducted a retrospective study in the department of colorectal surgery, Christian Medical College; Vellore from 2011 to 2017 to compare the perineal wound-related complications following CAPE and ELAPE. The data were retrieved from the prospectively maintained computerized inpatient and out-patient follow up records and comparisons were made in terms of incidence of perineal wound outcomes, need for reoperations and duration of hospital stay. A total of 138 patients underwent CAPE and 57 patients underwent ELAPE over a period of 7 years. There was no statistical difference in baseline characteristics and patients who underwent neo-adjuvant chemoradiation between the two groups. Perineal wound complications were seen in 63% (87) of the patients after CAPE compared to 64.9% (37) of the patients after ELAPE. There was no perineal herniation or wound dehiscence following ELAPE, whereas these complications occurred in 1 and 5 patients respectively after CAPE. Similarly, the incidence of reoperations was 8% in CAPE as compared to 5.4% in ELAPE although not statistically significant. There was no difference in the length of hospital stay. Hence, in our experience, perineal wound complications were similar in the Extralevator approach to APE (ELAPE) as compared to conventional APE (CAPE) for rectal adenocarcinoma.

MP60-12 MID-TERM RESULTS OF ANTERIOR URETHROPLASTY WITH TISSUE-ENGINEERED ORAL MUCOSA GRAFT MUKOCELL®

INTRODUCTION AND OBJECTIVE: Anterior urethroplasty with buccal mucosa grafting is the standard procedure for recurrent urethral strictures of ≥2 cm length. Trying to avoid oral complications through harvesting buccal mucosa, a tissue-engineered oral mucosa graft (MukoCell®) was manufactured. Current multicenter retrospective studies report success rates of 67-84%. The objective of our institutional retrospective analysis is the assessment of the mid-term efficacy and complications of this method. METHODS: Between 05/2016 and 06/2019 a total of 77 patients with anterior urethral strictures underwent a urethroplasty with MukoCell®. Our cohort consisted of 45 patients with bulbar strictures (78,9%), 15 with penobulbar (19,5%), 11 with penile (14,3%), 4 with membranous (5,2%) and 2 with simultaneous bulbar and penile strictures (2,6%) respectively. Mean patient age was 59 years (range 16 to 87) with mean 2,5 previous endoscopic or anastomotic procedures (range 0 to 8). 4 different surgeons performed in 61 cases ventral/dorsal onlay techniques (79,2%), in 5 cases inlay-ASOPA technique (6,5%) and in 11 cases combined (Palminteri et al.) technique (14,3%). Mean stricture length was 5,3 cm (range 2 to 16). 8 (10,4%) strictures were traumatic, 39 (50,6%) iatrogenic, 21 (27,3%) idiopathic, 1 (1,3%) radiogenic, 1 (1,3%) associated with Lichen sclerosus, 2 (2,6%) former hypospadias and 2 (2,6%) had other causes. IPSS-Score, Uroflowmetry and post void residual measurement were recorded pre- and postoperatively twice a year. Retrograde urethrography was performed pre- and 3 weeks postoperatively and repeated by suspicion of recurrence. RESULTS: Mean follow up was 24 months (range 8 to 43). 24 patients (31,2%) developed a recurrence of the stricture (14 with bulbar, 4 penobulbar, 3 penile, 2 membranous and 1 simultaneous bulbar and penile localization and mean 2,3 previous endoscopic operations (range 1-6) after mean 6,5 months (range 1,5 to 17). None perioperative hemorrhage occurred in all patients. We reported 5 cases of perineal wound dehiscence, 5 UTIs, 7 contrast leaks in the postoperative urethrography and 1 urethrocutaneous fistula requiring surgical intervention (Clavien-dindo 3b). No local (oral-urethral) or general adverse events related to the use of MukoCell® were observed. CONCLUSIONS: The recurrence-free rate of anterior urethroplasty using MukoCell® in our hands was 68,8% after a two-year follow-up. A prospective multicenter study comparing „head-to-head“ the efficiency of this graft with the native oral mucosa will be initiated in Germany in 2020. Source of Funding: none
