Malignant Chest Wall Tumors: Complex Defects and Their Management-A Review of 181 Cases.

BACKGROUND: Chest wall tumors are a heterogeneous group of tumors that are managed by surgeons from diverse specialties. Due to their rarity, there is no consensus on their diagnosis and management. MATERIALS: This retrospective, descriptive analysis includes patients with malignant chest wall tumors undergoing chest wall resection. Tumors were classified as primary, secondary, and metastatic tumors. The analysis includes clinicopathological characteristics, resection-reconstruction profile, and relapse patterns. RESULTS: A total of 181 patients underwent chest wall resection between 1999 and 2020. In primary tumors (69%), the majority were soft tissue tumors (59%). In secondary tumors, the majority were from the breast (45%) and lung (42%). Twenty-five percent of patients received neoadjuvant chemotherapy, and 98% of patients underwent R0 resection. Soft tissue, skeletal + soft tissue, and extended resections were performed in 45%, 70%, and 28% of patients, respectively. The majority of patients (60%) underwent rib resections, and a median of 3.5 ribs were resected. The mean defect size was 24 cm2. Soft tissue reconstruction was performed in 40% of patients, mostly with latissimus dorsi flaps. Rigid reconstruction was performed in 57% of patients, and 18% underwent mesh-bone cement sandwich technique reconstruction. Adjuvant radiotherapy and chemotherapy were given to 29% and 39% of patients, respectively. CONCLUSIONS: This is one of the largest single-institutional experiences on malignant chest wall tumors. The results highlight varied tumor spectra and multimodality approaches for optimal functional and survival outcomes. In limited resource setting, surgery, including reconstructive expertise, is very crucial.

The long-term impact of vaginal surgical mesh devices on pain clinic and psychological service referrals, anti-inflammatory testing and pelvic scans in UK primary care: A cohort study with the Clinical Practice Research Datalink.

OBJECTIVE: To examine long-term complications in women with stress urinary incontinence (SUI) and pelvic organ prolapse (POP), with and without surgical mesh implants. DESIGN: Longitudinal open cohort study from 1 April 2006 (or 1 April 2012) to 30 November 2018. SETTING: The Clinical Practice Research Datalink (CPRD) Gold database, which is linked to Hospital Episodes Statistics (HES) inpatient data, the HES Diagnostic Imaging Dataset (DID), Office for National Statistics mortality data and Index of Multiple Deprivation socio-economic status data. SAMPLE: Women aged ≥18 years with a diagnostic SUI/POP Read code. METHODS: Rates are estimated using negative binomial regression. MAIN OUTCOME MEASURES: Rates of referrals for: psychological and pain services; urinalysis, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) testing; and pelvic ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) scans. RESULTS: A cohort of 220 544 women were eligible for inclusion; 74% (n = 162 687) had SUI, 37% (n = 82 123) had POP and 11% (n = 24 266) had both. Rates of psychological referrals and CT scans were lower in women with SUI mesh surgery, but this was offset by higher rates of CRP testing in women with SUI or POP mesh, MRI scans in women with SUI mesh, and urinalysis testing and referrals to pain clinics for women with POP mesh. CONCLUSIONS: Our results suggest a higher burden of morbidity in women with SUI/POP mesh surgery, and that these women may require ongoing follow-up in the primary care setting.

Hydrogel-mesh composite for wound closure.

During operations, surgical mesh is commonly fixed on tissues through fasteners such as sutures and staples. Attributes of surgical mesh include biocompatibility, flexibility, strength, and permeability, but sutures and staples may cause stress concentration and tissue damage. Here, we show that the functions of surgical mesh can be significantly broadened by developing a family of materials called hydrogel-mesh composites (HMCs). The HMCs retain all the attributes of surgical mesh and add one more: adhesion to tissues. We fabricate an HMC by soaking a surgical mesh with a precursor, and upon cure, the precursor forms a polymer network of a hydrogel, in macrotopological entanglement with the fibers of the surgical mesh. In a surgery, the HMC is pressed onto a tissue, and the polymers in the hydrogel form covalent bonds with the tissue. To demonstrate the concept, we use a poly(N-isopropylacrylamide) (PNIPAAm)/chitosan hydrogel and a polyethylene terephthalate (PET) surgical mesh. In the presence a bioconjugation agent, the chitosan and the tissue form covalent bonds, and the adhesion energy reaches above 100 J⋅m-2 At body temperature, PNIPAAm becomes hydrophobic, so that the hydrogel does not swell and the adhesion is stable. Compared with sutured surgical mesh, the HMC distributes force over a large area. In vitro experiments are conducted to study the application of HMCs to wound closure, especially on tissues under high mechanical stress. The performance of HMCs on dynamic living tissues is further investigated in the surgery of a sheep.

Anatomical outcomes and complications of sacrocolpopexy using Surelift Uplift mesh: A multicentric observational study.

OBJECTIVE: The study evaluated the anatomical and functional outcomes, as well as the safety data of laparoscopic sacrocolpopexy (LSC) for pelvic organ prolapse (POP) using a lightweight macroporous mesh. METHODS: A multicentric observational study was developed including five expert centers between March 2011 and December 2019. Inclusion criteria were female patients with symptomatic ≥stage II POP (POP-Q classification), who underwent a LSC. A lightweight and macroporous mesh device (Surelift Uplift) was used. Baseline anatomical positions were evaluated using POP-Q stage. The anatomical outcomes and procedural complications were assessed during the postoperative period. Primary outcomes were anatomical success, defined as POP-Q stage ≤I, and subjective success, defined as no bothersome bulge symptoms, and no repeat surgery or pessary use for recurrent prolapse. RESULTS: A total of 325 LSCs were analyzed with a median patient age of 66 (interquartile range [IQR] 61-73). After a median follow-up of 68 months (IQR 46.5-89), anatomical success was found in 88.9%, whereas subjective success was seen in 98.5% of the patients. Recurrent prolapse presented as cystocele (1.5%). Reported complications were bladder (4.6%) or rectum lesions (0.6%), de novo urinary incontinence (12.9%), and mesh extrusion (1.2%). CONCLUSIONS: LSC provides significant clinical improvement and excellent anatomical results, with a low risk of serious complications for women with ≥2 grade POP in a real clinical practice setting.

Comparison of single absorbable tacker vs. conventional method in fixating the mesh in bilateral inguinal hernia undergoing laparoscopic transabdominal preperitoneal (TAPP): A randomized control trial study.

Background: The current study aims to investigate the superior mesh fixation method, single absorbable tacker versus conventional method, in patients undergoing bilateral inguinal hernia repair through the laparoscopic total abdominal preperitoneal (TAPP) approach. Materials and Methods: The current randomized clinical trial has been conducted on 81 patients undergoing bilateral hernia repair through TAPP. The patients were randomly assigned into one of the mesh fixation groups including single absorbable tacker (Group S) (n = 41) and conventional method (Group C) (n = 40). All patients were assessed during the hospital stay and 1 month postoperatively to assess the surgery-associated complications and days for return to daily activity. Eura-Hs questionnaire was applied to assess the quality of life (QOL) after hernia surgery during 12-month follow-up. Results: The duration of bilateral inguinal hernia operation (P = 0.067), postoperative urinary catheterization (P = 0.813), and hospital stay duration (P = 0.779) did not differ between the groups; whereas Group C significantly required a longer time for returning to daily activity (P < 0.001). Only a patient in Group C represented hematoma (P = 0.494). Seroma incidence was not statistically different between the two groups (P = 0.712). Postoperative pain was statistically less in Group S (P < 0.001 for all the assessments). Postoperative QOL within a year after hernia repair revealed an insignificant difference between the groups in general (P > 0.05); however, a pain subscale was significantly less in Group S (P = 0.002). Conclusion: Based on the findings of this study, a single absorbable tacker was generally superior to the conventional method considering its less pre- and postoperative complications. However, the two methods did not differ regarding 1-year follow-up QOL.

Practical Mouse Model to Investigate Therapeutics for Staphylococcusaureus Contaminated Surgical Mesh Implants.

INTRODUCTION: The use of prosthetic mesh in hernia repair provides a powerful tool to increase repair longevity, decrease recurrence rates, and facilitate complex abdominal wall reconstruction. Overall infection rates with mesh are low, but for those affected there is high morbidity and economic cost. The availability of a practicable small animal model would be advantageous for the preclinical testing of prophylactics, therapeutics, and new biomaterials. To this end, we have developed a novel mouse model for implantation of methicillin-resistant Staphylococcus aureus-infected surgical mesh and provide results from antibiotic and immunotherapeutic testing. MATERIALS AND METHODS: Implantation of surgical mesh between fascial planes of the mouse hind limb was used to approximate hernia repair in humans. Surgical mesh was inoculated with methicillin-resistant Staphylococcus aureus to test the efficacy of antibiotic therapy with daptomycin and/or immunotherapy to induce macrophage phagocytosis using antibody blockade of the CD47 "don't eat me" molecule. Clinical outcomes were assessed by daily ambulation scores of the animals and by enumeration of mesh-associated bacteria at predetermined end points. RESULTS: A single prophylactic treatment with daptomycin at the time of surgery led to improved ambulation scores and undetectable levels of bacteria in seven of eight mice by 21 days postinfection. Anti-CD47, an activator of macrophage phagocytosis, was ineffective when administered alone or in combination with daptomycin treatment. Ten days of daily antibiotic therapy begun 3 days after infection was ineffective at clearing infection. CONCLUSIONS: This fast and simple model allows rapid in vivo testing of novel antimicrobials and immunomodulators to treat surgical implant infections.

Analysis of recurrence and risk factors in laparoscopic sandwich technique for parastomal hernia repair.

INTRODUCTION: Parastomal hernias are frequent and highly recurrent. The sandwich technique is a combination of the keyhole and Sugarbaker techniques, using a double intraperitoneal mesh. The objective of this study was to assess the outcomes of the sandwich technique, specifically focusing on recurrence rates. MATERIALS AND METHODS: Observational retrospective study conducted in two tertiary referral centers in Catalonia, Spain. All consecutive patients who underwent parastomal hernia repair using the sandwich technique between 1st January 2016 and 31st December 2021 were included. RESULTS: A total of 38 patients underwent the laparoscopic sandwich technique for parastomal hernia repair. The overall recurrence rate was 7.9% (3/38), with a median follow-up of 39 months (IQR: 12.3-56.5). According to the EHS classification for parastomal hernia, there were 47.4% (18/38) type I defects, 10.5% (4/38) type II defects, 28.9% (11/38) type III defects, and 13.2% (5/38) type IV defects. The used mesh was predominantly TiMesh® (76.3%; 29/38), followed by DynaMesh® IPOM (23.7%; 9/38). Patients with recurrence exhibited higher rates of seroma, hematoma, surgical site infection, and one case of early recurrence attributed to mesh retraction. Consequently, postoperative complications emerged as the primary risk factor for hernia recurrence. CONCLUSION: The sandwich technique demonstrated recurrence rates consistent with those reported in the existing literature.

Triple-compartment strategy for abdominal sacral colpopexy using PVDF mesh: one-year report of anatomical and subjective outcomes.

INTRODUCTION AND HYPOTHESIS: Abdominal Sacral Colpopexy (ASC) is one of the best surgical methods to repair apical or uterine prolapse. We aimed to evaluate the short-term results of a triple-compartment open ASC strategy using polyvinylidene fluoride (PVDF) mesh in the treatment of patients with severe apical or uterine prolapse. METHODS: Women with high-grade uterine or apical prolapse with or without cysto-rectocele were prospectively enrolled in the study from April 2015 to June 2021. We performed all-compartment repair using a tailored PVDF mesh for ASC. We assessed the severity of pelvic organ prolapse (POP) using the Pelvic Organ Prolapse Quantification (POP-Q) system at baseline and 12 months after the operation. The patients completed the International Continence Society Questionnaire Vaginal Symptom (ICIQ-VS) questionnaire at baseline, 3, 6, and 12 months postoperatively. RESULTS: Thirty-five women with a mean age of 59.8±10.0 years were included in the final analysis. Stage III and stage IV prolapse was evident in 12 and 25 patients, respectively. After 12 months, the median POP-Q stage was significantly lower compared to the baseline (4 vs 0, p=<0.0001). Vaginal symptoms score was also reduced significantly at 3-month (7.5±3.5), 6-month (7.3±3.6), and 12-month (7.2±3.1) compared to the baseline (39.5±6.7) (p values < 0.0001). We did not observe any mesh extrusion or high-grade complications. Six (16.7%) patients had cystocele recurrence during the 12-month follow-up, and two of them needed reoperation. CONCLUSIONS: Our short-term follow-up showed that using an open ASC technique with PVDF mesh in treating high-grade apical or uterine prolapse is associated with a high rate of procedural success and low rates of complication.

Clinical outcomes and complications of laparoscopic sacrocolpopexy with versus without concomitant hysterectomy for pelvic organ prolapse in Hong Kong Chinese patients after median follow-up of 7 years.

INTRODUCTION AND HYPOTHESIS: This retrospective cohort study is aimed at comparing outcomes and complications of laparoscopic sacrocolpopexy (LSC) with or without concomitant hysterectomy in the Hong Kong Chinese population. METHODS: Women with stage II or above uterine or apical vault prolapse who underwent LSC with or without concomitant hysterectomy in a regional referral unit from 2007 to 2019 were included. The primary objectives were to compare the anatomical outcomes by pelvic organ prolapse quantification system (POP-Q) and recurrence of apical vault prolapse (≥stage II). The secondary objective was to compare the functional outcomes and complications. Anatomical recurrence and incidence of mesh exposure were analyzed using the Kaplan-Meier method. Cox proportional hazard regression was performed to identify risk factors of anatomical recurrence. RESULTS: Seventy-six women were included for analysis. The recurrence rate of apical vault prolapse was 3.9% after a median follow-up time of 83 months (20-190 months). A significant reduction of POP-Q scores of three compartments in both groups of women were demonstrated (p<0.001). There was no difference between the two groups in terms of functional outcomes and complications. 6.6% of women developed mesh exposure. The time to recurrence of apical vault prolapse was shorter in women who had LSC with prior hysterectomy (p =0.019). No risk factors were identified for recurrence of apical vault prolapse. CONCLUSIONS: Laparoscopic sacrocolpopexy with concomitant hysterectomy is comparable with LSC alone. The recurrence and complication rates are low. We suggest that LSC with concomitant hysterectomy might be offered to women with pelvic organ prolapse, with women's preference taken into account.

Pelvic organ prolapse recurrence after pregnancy following uterine-sparing prolapse repair: a systematic review and meta-analysis.

INTRODUCTION: We sought to determine rates of pelvic organ prolapse (POP) recurrence following pregnancy and delivery in reproductive-age women with prior hysteropexy. METHODS: Scopus, MEDLine, EMBASE, Cochrane Library, and ClinicalTrials.gov databases were searched from inception to May 2020 for combinations of any of the keywords: "pregnancy", "delivery", "fertility", or "cesarean" with a comprehensive list of uterine-sparing surgical procedures for POP repair. Using approach, 1,817 articles were identified describing surgical, uterine-sparing POP repair techniques and subsequent pregnancy and delivery outcomes in reproductive-age women.   RESULTS: Twenty-seven studies describing 218 pregnancies, including 215 deliveries and 3 abortions, were summarized using narrative review and descriptive statistics. Successful pregnancies were reported following a diverse range of uterine-sparing prolapse repairs, both native tissue and mesh-augmented, that utilized vaginal, open abdominal, and laparoscopic approaches. We observed shifts from native tissue repairs to mesh-augmented laparoscopic repairs over time. POP recurrence occurred in 12% of subjects overall, 15% after vaginal and 10% after abdominal prolapse repairs. While meta-analysis identified higher recurrence rates after vaginal delivery (15%) than cesarean section (10%), due to small study numbers, multiple confounders, and heterogeneity between studies, no significant differences in recurrence rates could be identified between vaginal and abdominal surgical approaches, utilization of mesh augmentation, or mode of delivery. CONCLUSION: Although literature on pregnancy following uterine-sparing POP repair is limited, available data suggest that prolapse recurrence after pregnancy and delivery remains similar to that after prolapse repair without subsequent pregnancies with few documented perinatal complications.

Short-term complications after onlay versus preperitoneal mesh repair of umbilical hernias: a prospective randomized double-blind trial.

PURPOSE: To compare the incidence of surgical site occurrences (SSOs) following onlay versus preperitoneal mesh placement in elective open umbilical hernia repairs. METHODS: This study presents a secondary analysis of a randomized double-blind trial conducted on female patients with primary umbilical hernias admitted to a general hospital, in a residency training program setting. Fifty-six subjects were randomly assigned to either onlay (n=30) or preperitoneal (n=26) mesh repair group. Data on baseline demographics, past medical history, perioperative details, postoperative pain (visual analogue scale (VAS)), wound-related complications, and recurrence were assessed using a standardized protocol. RESULTS: No statistically significant differences were observed between groups regarding patients' demographics, comorbidities, or defect size. Operative time averaged 67.5 (28-110) min for onlay and 50.5 (31-90) min for preperitoneal repairs, p=.03. The overall rate of SSOs was 21.4% (n=12), mainly in the onlay group (33% vs 7.7%; p=0.02, 95% CI 0.03-0.85) and mostly due to seromas. There were no between-group significant differences in postoperative VAS scores at all timepoints. After a maximum follow-up of 48 months, one recurrence was reported in the onlay group. By logistic regression, the onlay technique was the only independent risk factor for SSOs. CONCLUSION: The presented data identified a decreased wound morbidity in preperitoneal umbilical hernia repairs, thus contributing to the limited body of evidence regarding mesh place selection in future guidelines. Further cases from this ongoing study and completion of follow-up are expected to also compare both techniques in terms of long-term outcomes.

Efficacy of mesh coverage in surgical bullectomy for primary spontaneous pneumothorax: A systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Thoracic surgeons are now adopting a new method of using a mesh covering to reduce recurrence in surgical pleurodesis for pneumothorax. We aimed to review the literature and compare the outcomes of using mesh covering as an additional procedure during surgical pleurodesis. METHODS: A comprehensive search was performed from inception to October 2022 on PubMed, Embase, Cochrane and Scopus. Randomised controlled trials (RCTs) and observational cohort studies (OCSs) comparing the use of mesh coverage, and different materials were included. Data were extracted to compare recurrence and other outcomes using a random effect model. RESULTS: 23 studies consisting of 2 RCTs and 21 OCSs totalling 5092 patients were included. Patients with a mesh had a significantly lower recurrence (OR = 0.22, 95% CI 0.12-0.42, p < 0.0001) and a shorter duration of chest tube drainage (SMD = -0.74 days, 95% CI -0.28 to -1.20, p < 0.0001) but no significant difference in the length of operation. The use of polyglycolic acid (PGA) and vicryl mesh was associated with a significantly shorter duration of chest tube drainage [(PGA, SMD = 0.83 days, 95% CI 0.14-1.52, p < 0.0001), (vicryl, SMD = 1.06 days, 95% CI 0.71-2.82, p = 0.0005)]. They also had a shorter post-operative length of stay than oxidized regenerative cellulose (ORC) but this was not statistically significant. CONCLUSION: The use of a mesh material reduced the incidence of post-operative air leaks in the short term and the recurrence rate in the long term. Some mesh materials such as PGA and vicryl performed better than other materials.

Vertical Bone Augmentation With Customized CAD/CAM Titanium Mesh for Severe Alveolar Ridge Defect in the Posterior Mandible: A Case Letter.

Implant rehabilitation after implant removal is a major challenge, especially in mandibular posterior arches. This case report describes the reconstruction of a severe vertical bone defect using customized titanium mesh covered by collagen membrane and solid advanced platelet-rich fibrin, combined with autogenous bone, deproteinized bovine bone mineral, and injectable platelet-rich fibrin after implant removal caused by advanced peri-implantitis. This individualized titanium mesh may be a reliable technique for severe alveolar ridge reconstruction, with the additional benefits of reduced surgery time and a simplified operation.

Quality of life on type 2 diabetes patients in Indonesia: Systematic review.

Objectives: To review various quality of life questionnaires related to patients of type 2 diabetes mellitus. Method: The systematic review comprised search on SAGE, PubMed, ProQuest, Ebsco and Google Scholar databases for studies using quality of life questionnaires related to patients of type 2 diabetes mellitus published between January 2012 and January 2022 in either English or Bhasha language. Data extraction and assessment was done in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist. RESULTS: Of the 25 studies reviewed, 23(92.2%) were in the English language. They were conducted in 17(51.5%) of the 33 provinces in Indonesia. The questionnaires used were 36-item Short Form 8(32%), EuroQol 5-dimension 5-level scale 6(24%), World Health Organisation Quality of Life-Brief version 6(24%), Diabetes Quality of Life 3(12%) and Diabetes Quality of Life Clinical Trial Questionnaire 2(8%). Variables associated with the quality of life of the diabetics included education, gender and age. The internal factors included glycaemic control, psychological condition, self-efficacy, perception of illness, self-care management, medication adherence, neutrophil-lymphocyte ratio and complications. The external factors included family support, medication counselling and pharmacists' intervention. CONCLUSIONS: Many instruments measure quality of life related to patients of diabetes mellitus. Countries with different socio-cultural forms have different quality of life perspectives, and the assessment tool should be picked accordingly.

Tension-Free Vaginal Tape and Polyacrylamide Hydrogel Injection for Primary Stress Urinary Incontinence: 3-Year Followup from a Randomized Clinical Trial.

PURPOSE: We sought to determine whether polyacrylamide hydrogel (PAHG) is noninferior to tension-free vaginal tape (TVT) in the treatment of women with primary stress urinary incontinence (SUI). MATERIALS AND METHODS: In this noninferiority trial, 223 women eligible for operative SUI treatment were randomized for TVT (110) or PAHG (113). Primary outcome was patient satisfaction and the noninferiority margin for the difference was 20%. Secondary outcomes were effectiveness and complications. RESULTS: At 3 years, 188 (84.3%) women attended the followup. The satisfaction score (visual analogue scale 0-100) median was 98.5 (IQR 90-100) in the TVT group and 90.0 (IQR 70-100) in the PAHG group, whereas a score ≥80 was reached in 87 (94.6%) and 65 (67.7%), respectively (difference 26.9%, 95% CI 16.7% to 36.8%). Thus, PAHG did not meet the noninferiority criteria set in our study. The cough stress test was negative in 88 (95.7%) of TVT patients vs 75 (78.1%) of PAHG patients (difference 17.5%, 95% CI 8.6% to 26.9%). Any peri- or postoperative complication before crossover between the groups was detected in 40 (43.5%) women in the TVT group and 23 (24.0%) women in the PAHG group (difference 19.5%, 95% CI 6.8% to 31.4%). CONCLUSIONS: In midterm followup, PAHG did not reach in patient satisfaction the noninferiority set in our study. Furthermore, mid urethral TVT slings show better subjective and objective cure rates than PAHG. However, complications were more often associated with TVT. Since the majority of PAHG treated women were also cured or improved, primary SUI women can be offered PAHG as a safe and durable alternative treatment.

The Evolving Story of Mesh Mid Urethral Slings: The Surgeon's Perspective.

PURPOSE: The objective of this study was to obtain the perspectives of surgeons who treat female stress urinary incontinence (SUI) and better understand their range of experiences with mesh mid urethral sling (MUS) surgery. MATERIALS AND METHODS: This qualitative study recruited gynecologic and urological surgeons who treat SUI. Surgeons were interviewed by phone and in person using a standardized interview guide. Interviews were transcribed, de-identified, and analyzed by 2 independent researchers. The transcripts were coded and summarized using the principles of thematic analysis. The research team came to consensus that a saturation of ideas representing a diverse demographic of surgeons had been achieved. RESULTS: Twenty-four interviews of surgeons from diverse geographic locations and practice types were performed. Many surgeons described MUS surgery as rewarding and favorably impactful for women with SUI, while others grappled with the serious risks associated with MUS surgery. Those who had treated women with life-altering pain after MUS recounted impactful patient stories. Many stated that recognition, acknowledgement, and appropriate referral of complications were fundamental to responsible and ethical care. Some surgeons expressed frustration and concern about the raised level of controversy and anxiety regarding the MUS landscape. All participants expressed that there was substantial room for improvement in multiple domains. Participants also shared their optimal strategies relevant to MUS surgery. CONCLUSIONS: Despite diverse views regarding the role of the MUS, there was agreement among surgeons that the surgeon-patient relationship, thorough informed consent and patient counseling, and accountability are essential when implanting MUSs.

Supracervical Hysterectomy Is Protective against Mesh Complications after Minimally Invasive Abdominal Sacrocolpopexy: A Population-Based Cohort Study of 12,189 Patients.

PURPOSE: Although minimally invasive (robotic or laparoscopic) abdominal sacrocolpopexy (MISC) has become the new gold standard for durable pelvic organ prolapse repair after the vaginal mesh controversy, current literature is limited. Our objective was to study reoperation for mesh complications after MISC. MATERIALS AND METHODS: All women undergoing MISC in California from January 2012 to December 2018 were identified from Office of Statewide Health Planning and Development data sets using appropriate ICD-9/10 (International Classification of Diseases 9th/10th Revision) and CPT® (Current Procedural Terminology) codes. Univariate and multivariable analyses were performed to assess associations between patient demographics, surgical details and our primary outcomes: rates of reoperation for a mesh complication. RESULTS: Of 12,189 women undergoing MISC 8,398 (68.9%) had concomitant hysterectomy. Total hysterectomy (TH) and supracervical hysterectomy (SCH) were performed in 5,027 (41.2%) and 3,371 (27.6%) cases, respectively. Reoperation rates for mesh complications were lower after SCH vs TH (overall: 0.7%, mean followup time 1,111 days vs 3.1%, mean followup time 1,095 days, p <0.001; subcohort with at least 4 years of followup: 2.1% vs 8.9%, p <0.001). Additionally, mesh complication rates were higher even if TH was performed remotely, as compared to concomitant SCH (5.2% vs 0.7%, p <0.001). The increased risk for reoperation due to mesh complications after TH was preserved on multivariable analysis (OR 4.20, 95% CI 2.72‒6.50, p <0.001). CONCLUSIONS: Concomitant TH at time of MISC is associated with a significantly higher rate of mesh complication as compared to SCH. The increased risk of a mesh complication associated with TH is present even if the TH was performed prior to the MISC.

Long-term postoperative follow-up results of transobturator autologous rectus fascial sling versus transobturator tension-free vaginal tapes for female stress urinary incontinence: Randomized controlled clinical trial.

AIMS: To evaluate the outcomes of a new surgical technique for the treatment of stress urinary incontinence (SUI). METHODS: This randomized study included 132 index patients from January 2017 to May 2021, 60 applied with autologous facia and 60 with transobturator tension-free vaginal tape (TVT-O). The primary endpoint was dryness (negative stress test and 0 pad use per day) and this was assessed at 3, 6, 12, and 24 months. The secondary endpoints were the International Consultation on Incontinence Questionnaire short form (ICIQ-SF) and the urinary incontinence quality of life (QoL) at 3, 6, 12, and 24 months. RESULTS: The dryness rate at 24 months was 92.4% (49/53) for patients with transobturator autologous rectus fascial sling (TO-AFS) and 94.6% (53/56) for those with TVT-O (p = 0.47). No difference was determined between the TO-AFS and TVT-O groups in respect of the ICIQ-SF and QoL scores at 2 years postoperatively (p = 0.87). There were five postoperative complications in the TO-AFS group (one urinary retention, one hematoma at suprapubic incision line, and three intermittent groin pains) and four in the TVT-O group (four persistent groin pain) (p = 0.98). CONCLUSIONS: The objective cure rates of the 24-month outcomes of TO-AFS indicate that this novel surgical technique seems to be a highly effective, safe, and feasible procedure for the treatment of SUI, but further studies including long-term follow-up are mandatory to confirm these preliminary data.

Prevention of incisional hernia after single-port sleeve gastrectomy (PRISM): a prospective non-randomized controlled study.

BACKGROUND: SPSG carries a risk of incisional hernia, particularly in patients with high body mass index. Prophylactic mesh placement with either permanent or absorbable mesh could decrease the occurrence of incisional hernia, with uncertainty on other postoperative parietal complications. METHODS: This is a non-randomized monocentric single-blinded prospective study. High-risk patients (body mass index ≥ 45 kg/m2) underwent either 3 strategies of parietal closure (suture with or without permanent or absorbable mesh) during SPSG. The primary outcome was the occurrence of radiologically defined incisional hernia during the first postoperative year. Secondary outcomes included surgical site infection rates and postoperative pain. RESULTS: Between November 2018 and November 2019, 255 patients were included (85 in each group). All patients reached one-year postoperative follow-up. Significantly more incisional hernias were observed in the no mesh group in comparison with permanent and absorbable mesh groups, respectively (20% vs. 7.1% vs. 5.1%, P = 0.005). No difference was observed in mesh groups. No difference was observed regarding other parietal complications. One patient in the absorbable mesh group presented a superficial surgical site infection and required surgical drainage without mesh removal and one patient in the permanent mesh group presented a parietal hematoma and required surgical drainage with mesh removal. Twenty-six (92.8%) asymptomatic patients presented incisional hernia discovered on the one-year CT-scan. CONCLUSIONS: Prophylactic mesh placement during SPSG decreases the occurrence of postoperative incisional hernia. Routine permanent mesh placement could be proposed in high-risk patients.

Transvaginal repair of anterior vaginal wall prolapse with polyvinylidene fluoride (PVDF) mesh: an alternative for previously restricted materials?

INTRODUCTION AND HYPOTHESIS: To study the mid-term safety and functional outcomes of transvaginal anterior vaginal wall prolapse repair using polyvinylidene fluoride (PVDF) mesh (DynaMesh®-PR4) by the double trans-obturator technique (TOT). METHODS: Between 2015 and 2020, we prospectively included women with symptomatic high-stage anterior vaginal wall prolapse with or without uterine prolapse or stress urinary incontinence (SUI) in the study. The patients underwent transvaginal repair of the prolapse using PVDF mesh in two medical centers. We followed all patients for at least 12 months. We recorded the characteristics of vaginal and sexual symptoms, urinary incontinence, and prolapse stage pre- and postoperatively using International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS), International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF), and Pelvic Organ Prolapse Quantification (POP-Q) system, respectively. RESULTS: One hundred eight women were included in the final analysis with a mean follow-up time of 34.5 ± 18.6 months. The anatomical success was achieved in 103 (95.4%) patients. There was a significant improvement in patients' vaginal symptoms, urinary incontinence, and quality of life scores postoperatively (p < 0.0001). Only six patients (5.5%) had mesh extrusion, five of whom were managed successfully. The total rates of complications and de novo urinary symptoms were 21.3% and 7.4%, respectively. Significant pain was reported in 17 cases (15.7%). CONCLUSION: Our findings show that using PVDF mesh in the double TOT technique for anterior vaginal wall prolapse repair is a safe procedure with high anatomic and functional success rates and acceptable complication rates in mid-term follow-up.
