Management of Sacrocolpopexy Mesh Complications-A Narrative Review and Clinical Experience from a Large-Volume Center.

Despite the reputation of sacrocolpopexy as a highly durable reconstructive surgery for pelvic organ prolapse, mesh-related complications remain a significant deterrent for patients. This review discusses the incidence, presentation, diagnosis, management and prevention of sacrocolpopexy mesh complications. We reviewed the literature on sacrocolpopexy focusing on long-term mesh complications and their management. As the literature is not specifically robust, we also give our recommendations based on experience from a large-volume center. Intraoperative videos and images are provided to illustrate findings and management techniques. Sacrocolpopexy mesh complications include vaginal mesh exposure; bladder or bowel erosions; inflammatory and infectious conditions including spondylodiscitis; and mesh-related pain. Presentation ranges from overt symptoms such as mesh palpated in the vagina to insidious-like spondylodiscitis manifesting as back pain and malaise. Diagnosis relies on methodical history taking, review of operative reports, and a physical examination, with office-based endoscopy studies and imaging as indicated. Various management options have been described in the literature. We recommend an expectant approach for asymptomatic patients; For symptomatic vaginal exposure, we encourage removal of entire mesh arm(s) via an abdominal approach; however, many prefer to utilize a transvaginal or partial excisional approach first. Spondylodiscitis is managed with long-term antibiotics and often requires mesh removal. Prevention strategies include using a lightweight polypropylene mesh attached to well- vascularized vaginal walls, avoiding direct placement on any sutured vaginotomy or cystotomy. Delayed absorbable monofilament suture is non-inferior to permanent suture. Sacrocolpopexy mesh complications can be challenging to diagnose and manage. Symptomatic cases often require a proactive approach; listening to patients when they describe persistent symptoms with postoperative onset; a low threshold for further evaluation; and upfront discussion of management options.

Inguinal hernia recurrence after laparoscopic mesh removal for chronic pain: a single-center experience with 11years of practice.

Up to 12% of patients undergoing minimally invasive inguinal hernia repair may develop chronic postoperative inguinal pain (CPIP), possibly explained by the presence of mesh. Recent studies reported that laparoscopic mesh removal is feasible and safe. However, the risk of a hernia recurrence is unknown. This observational study describes the rate of hernia recurrence and evolution in pain score following laparoscopic mesh removal for CPIP after preperitoneal inguinal hernia repair. Prospectively collected questionnaires and operative notes of consecutive patients undergoing a laparoscopic mesh removal for CPIP in our center of expertise between November 2011 and July 2022 were studied. Pain scores were quantified using the Numeric Pain Rating Scale (NRS, 0-10). The presence of a hernia recurrence was based on patient history and clinical findings. A total of 89 patients underwent laparoscopic mesh removal, and data of 83 patients (93% response rate) were available for analysis. Median decrease in pain score (NRS) after mesh removal was 4 (range + 2 to -9). After a median 4.3years follow up period, a hernia recurrence was present in 18 patients (21.7%). Of these, eight were symptomatic requiring correction using a Lichtenstein repair with a favorable outcome whereas a wait-and-see approach was successfully followed in the remaining 10 patients. Laparoscopic mesh removal for CPIP following preperitoneal inguinal hernia repair resulted in an inguinal hernia recurrence in one of five patients requiring remedial surgery in one in ten patients. This knowledge may inform the preoperative counseling process.

The Impact of Smoking on Sacrocolpopexy Perioperative Outcomes: An Observational Study.

Tobacco smoke is a modifiable risk factor that surgeons discuss with patients prior to undergoing sacrocolpopexy or mesh revision surgery. The aim of the study was to investigate the effect of smoking on perioperative outcomes after sacrocolpopexy for pelvic organ prolapse and mesh revision repair. This was a retrospective cohort study of data obtained from the National Surgical Quality Improvement Project's database. Women who underwent surgery for pelvic organ prolapse via abdominal sacrocolpopexy (ASCP) or minimally invasive sacrocolpopexy (MISCP) or prolapse mesh revision surgery from 2011 to 2021 were identified and compared based on current tobacco use. Demographic, medical, and surgical history, as well as intraoperative and 30-day perioperative outcomes, were compared. Multivariate analysis was performed. Overall, 21,980 women underwent MISCP (8.60% smokers) and 3,775 underwent ASCP (8.74% smokers). Postoperative wound infections were more common after sacrocolpopexy in patients who smoked. Readmission after MISCP was more common in smokers. The composite perioperative morbidity score was different between smokers and nonsmokers for MISCP (P = 0.001) and ASCP (P = 0.002). Multivariate analyses of MISCP outcomes found an association between smoking and wound infection, readmission, and composite score. Multivariate analyses of ASCP outcomes found an association between smoking and wound infection. Overall 2,160 patients underwent mesh removal by any modality (16.57% smokers), and no difference in perioperative outcomes between smokers and nonsmokers for mesh removal was found. An association was found between tobacco smoking and wound infection as well as other postoperative complications. Tobacco use prior to a mesh excision procedure does not appear to increase perioperative outcomes.

Mesh-associated pain syndrome: predictors for continence and prolapse mesh removal surgery in a single centre

ObjectiveOver the last two decades one of the main surgical treatment for stress urinary incontinence (SUI) and pelvic organ prolapse (POP) surgery was the insertion of non-absorbable mesh to restore continence and prolapse respectively. Over time complications arose including mesh-associated pain syndrome (MAPS), mesh exposure, mesh, erosion, chronic bladder/vaginal infections, and dyspareunia. Consequently, women chose surgical mesh removal to counter these problems. However, little is known about the demographics, medical co-morbidities, mesh types involved and the timing from mesh insertion to mesh removal. This retrospective study will look at which of these factors may be closely associated with mesh removal surgery.DesignRetrospective evaluation.SettingFemale Pelvic Medicine and Reconstructive Surgery (FPMRS) Clinic at University College London Hospitals NHS Foundation Trust.PopulationAll patients presenting to the FPMRS Clinic between June 2011 to December 2019, requesting mesh removal surgery with a history of MAPS and other mesh complications were included in this study.MethodsPatient demographics including age, ethnicity, obstetric history, and medical co-morbidities; type of mesh/anatomical route used; onset of symptoms; and time from insertion to removal were recorded.Main Outcome MeasuresDetermination of correlation coefficients between patient demographics, patient reported symptoms and mesh removal surgery.ResultsThree hundred and forty-five women with a history of MAPS were included in the study. Women in the 40–60 year old cohort accounted for 54.4% of mesh removal surgery; 54.8% had a BMI under 30 and almost 90% were Caucasian. 96.5% had had children, with over 77% having had a vaginal delivery. 91.9% of patients reported other health conditions including 18.8% with a concomitant history of mental health problems and 15.4% with a history of heart disease. Over 80% of women undergoing mesh removal surgery had a continence mesh (49% retropubic and 32% obturator continence mesh) removed, whereas 20% had an abdominal prolapse and/or vaginal prolapse mesh removed. The average time from mesh insertion to mesh removal was seven years, with the prevalence of mesh removal surgery averaging 85% (range 50–100%) depending on the comorbidity determined.ConclusionsAll women presented to the clinic with a history of MAPS and other comorbidities which may have influenced their decision to pursue mesh removal surgery. There were no specific predictors, other than chronic pain associated with mesh, determining which women underwent surgery, though those with continence mesh were more likely to do so.

New titanium mesh design method in customized bone regeneration of the jaws: preliminary study on a sample of 11 patients

The aim of this study is 1) to present a new method of virtually-designed custom made scaffolds to be employed in customized bone regeneration (CBR) for segmental jaw atrophies and 2) to evaluate long-term clinical results in terms of bone regeneration success and implant rehabilitation success. A total of 11 patients with edentulousness and bone atrophy in a localized area of the mandible or the maxilla were recruited for the study. To fulfill the research inquiries, CT images of the pre-regeneration mandibular or maxillary arch of each patient were collected. A dedicated Mevislab 2.4 software was employed to virtually design custom bone regeneration meshes designed to fit the atrophic sector of each patient's mandible or maxilla. Subsequently, a second Meshmixer software was used to refine the margins of each of the designed meshes. All patients underwent oral surgery, during which a mixture of autologous and heterologous bone in a 1:1 proportion was grafted into the atrophic site, a custom-made mesh was placed, and a resorbable membrane was inserted. The mesh was removed after this procedure, and implant rehabilitation was performed. All patients underwent the bone regeneration procedure, with eight undergoing titanium mesh removal. A total of seven patients completed implant rehabilitation. Average horizontal bone augmentation was 3.525 ± 1.36 mm; average vertical bone augmentation was 4.45 ± 2.22 mm. Implant survival was 92.85%. During the healing phase, complications occurred in 9.09% of patients. The use of dedicated software, Mevislab 2.4 and Meshmixer, for titanium mesh design is an accurate, predictable, effective, and quick-to-use method. The learning curve for design is uncomplicated and rapid. Mesh exposure does not necessarily lead to bone graft failure; this complication can be treated by chlorhexidine aids.

Surgical Treatment and Clinical Evaluation of Calvarial Metastases.

The aim of this study is to explore surgical treatment techniques and clinical attributes associated with calvarial metastases, while providing a comprehensive review of the treatment experiences relevant to this particular type of tumor. This study involves a retrospective analysis of clinical data from 12 patients diagnosed with calvarial metastatic tumors who underwent surgical intervention. Among these patients, 5 had a history of previous malignant tumor resections, while 7 presented with calvarial metastatic tumors as their initial symptom. In all cases, the surgical approach consisted of calvarial tumor resection followed by titanium mesh repair. Following the surgical intervention, all patients underwent a comprehensive course of treatment, encompassing both local radiotherapy and systemic chemotherapy. In 1 instance, a patient presented with multiple tumors located in the central area of the frontal bone and the right temporal bone. The larger tumor situated in the middle of the frontal bone was surgically excised, while the tumor in the right temporal bone was treated using radiotherapy. In 2 cases characterized by multiple metastases within the skull, a comprehensive excision of all tumors was accomplished in a single surgical procedure. In the remaining cases featuring a solitary metastatic growth, the respective tumors were surgically removed. There were 10 instances of dura mater invasion and 3 cases involving the invasion of brain tissue. Pathologic examinations revealed 1 case of metastatic lung adenocarcinoma, 1 case of metastatic paraganglioma, 1 case of metastatic hepatocellular carcinoma, 2 cases of metastatic thyroid carcinoma, and 7 cases of metastatic clear cell renal cell carcinoma. Throughout the follow-up period, spanning from 14 to 90 months, various outcomes were noted. These included three occurrences of in situ recurrence. In addition, 1 patient required 3 distinct surgical interventions, while 2 other patients underwent 2 separate surgical procedures each. Notably, 1 of these cases involved the exposure of the titanium mesh on the scalp, necessitating the removal of the titanium mesh. Regrettably, there have been 9 recorded fatalities among the patients, while 3 individuals have survived. Solitary metastasis of calvarium region is rare, and surgical resection is effective. However, it is necessary to extend the resection range and combine with local radiotherapy to avoid local recurrence. Surgical intervention can significantly enhance the quality of life for affected patients. The prognosis of the patients mainly depends on the treatment of the primary disease and the situation of important organ dissemination and treatment.

Diagnosis and treatment of abdominally inserted (sacrocolpopexy/sacrohysteropexy) mesh complications for vault/uterine prolapse

Background:Sacrohysteropexy and sacrocolpopexy are established treatments of uterine or vaginal vault prolapse respectively and involve insertion of mesh abdominally, often using permanent sutures and fixation devices. Complications following these procedures may be serious, and there is lack of evidence about long-term functional outcomes in terms of pain, dyspareunia and development of lower urinary tract and bowel symptoms. Objective:A non-systematic review of the available literature was performed and recommendations on assessment and management were developed by expert consensus. Conclusion:The current evidence is limited in quantity and quality, and recommendations on assessment management of mesh-related complications were made by experts in the field. Assessment and treatment of complications following abdominally placed mesh for pelvic organ prolapse will often require a multidisciplinary approach. Assessment may require EUA, and/or cystourethroscopy, sigmoidoscopy, and laparoscopy. MRI is the most useful imaging modality. Surgery to remove meshcarries a risk of urinary tract and bowel injury, as well as development of recurrent pelvic organ prolapse. A joint decision between the surgeon and the patient should be made before embarking on a partial removal of mesh; removal of all the mesh may be a better option albeit with higher risk of surgical complications. Complete removal of mesh and tacks or sutures from the sacral attachment may not be possible and is associated with risk of major haemorrhage.

Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) in Urogynecological Surgery: A Systematic Review.

Background: Minimally invasive surgery could improve cosmetic outcomes and reduce the risks of surgical injury with less postoperative pain and a quicker patient's discharge. Recently, transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has been introduced in urogynecology with exciting results. Evidence Acquisition: After PROSPERO registration (n°CRD42023406815), we performed a comprehensive literature search on Pubmed, Embase, and Cochrane CENTRAL, including peer-reviewed studies evaluating transvaginal natural orifice transluminal endoscopic surgery. No limits on time or type of study were applied. Evidence synthesis: Overall, 12 manuscripts were included in the analysis. Seven studies evaluated uterosacral ligament suspension, four studies evaluated sacral colpopexy, three evaluated sacrospinous ligament suspension, and one study evaluated lateral suspension. Overall success rates were high (>90%); however, definitions of success were heterogeneous. In terms of complication, most of the studies reported low-grade complications (Clavien-Dindo I and II); only two patients needed mesh removal because of mesh exposure. The risk of bias of the trials was rated in the medium to high-risk category. Conclusions: The present review highlights important initial results for vNOTES. Future randomized clinical trials are needed to better define its role in the management of urogynecological procedures.

The impact of diabetes and presurgical glycemic control on wound morbidity following open complex abdominal wall reconstruction: a single-center experience.

Numerous studies have identified diabetes mellites (DM) as a significant risk factor for postoperative wound morbidity, with suboptimal preoperative glycemic control (GC) posing an even greater risk. However, this data largely excludes ventral hernia patients. Our study examined the association between diabetes and preoperative GC and postoperative outcomes following open complex abdominal wall reconstruction (AWR). We identified diabetic patients who had undergone open, elective, clean VHR with transversus abdominis release (TAR) and permanent synthetic mesh at the Cleveland Clinic Foundation between January 2014 and December 2023. Their 30-day outcomes were compared to non-diabetic patients undergoing the same procedure. Subsequently, diabetic patients were categorized based on GC. status: "Optimal GC" (HbA1c < 7%), "Sub-optimal GC" (HbA1c 7-8.4%), and "Poor GC" (HbA1c ≥ 8.5%) and their outcomes were compared. 514 patients with DM who underwent clean elective TAR were identified, of which 431 met the inclusion criteria. GC was deemed optimal in 255 patients, sub-optimal in 128, and poor in 48 patients. Demographics were similar, except for anticoagulation treatment (p = 0.014). The entire study population exhibited significantly higher rates of wound morbidities and overall complications compared to non-diabetic patients. However, rates of surgical site infection (SSI), surgical site occurrence (SSO), SSO requiring procedural intervention (SSOPI), and reoperation did not differ significantly among the three cohorts of presurgical glycemic control (p = 0.82, p = 0.46, p = 0.51, p = 0.78), respectively. No occurrence of mesh removal was documented. In general, diabetes is a marker for increased wound morbidity and complications following complex abdominal wall reconstruction. However, we could not establish a hard cutoff to justify withholding surgery in symptomatic patients based on an arbitrary HbA1C level. We believe this data is important for shared decision-making when considering AWR for symptomatic ventral hernias in diabetic patients.

Five-year experience with titanium mesh for rigid chest wall reconstruction

ObjectiveTo characterize the performance of titanium mesh (TM) (off-label) for rigid chest wall reconstruction at a single institution over a 5-year period. MethodsBetween January 1, 2019, and May 15, 2023, 22 patients (median age, 61 years) underwent chest wall resection with TM reconstruction at Cleveland Clinic. Indications for resection included sarcoma (n = 15), breast cancer (n = 2), lung cancer (n = 2), chondroblastoma (n = 1), and benign neoplasm (n = 2). Patients were followed every 6 months with computed tomography scans for cancer recurrence. Continuous variables are summarized as median (interquartile range [IQR]); categorical variables, as frequency and percentage. Time to mesh fracture was assessed nonparametrically using Kaplan-Meier analysis. ResultsAmong the 22 patients over 21,870 patient-days of TM implantation, 21 (95%) had an R0 resection. The mean area of mesh coverage was 108 cm2 (IQR, 97-180 cm2). No patient experienced respiratory complications or mesh failure postoperatively. Of the 3 reoperations (13.6%), 2 were for delayed regional infection (at 7 and 12 months postoperatively), necessitating localized mesh removal, and the third was for local cancer recurrence. Fifteen implants developed visible fractures on imaging at a median time of 9 months after implantation. There were no adverse sequelae, including migration/erosion or clinical decline in respiratory function. ConclusionsChest wall resections, particularly those for sarcomas, require large margins for optimal oncologic outcomes. Rigid reconstruction of large defects is desirable, yet options are limited. TM reconstruction provides a promising alternative because of its biocompatibility, rigidity, robust incorporation into surrounding structures, and resistance to infection.

Abdominal Mesh Colpopexy Without Promontory Fixation: 10-Year Follow-up Results of the Peritoneocolpopexy Technique

ObjectivesTo restore apical vaginal prolapse support when the access to the promontory is challenging, a modified method of colpopexy may be needed. We present our 10-year results on the peritoneocolpopexy (PCP) technique without promontory fixation relying on unidirectional barbed delayed absorbable sutures (V-Loc). MethodsFourteen women who underwent PCP for vaginal vault prolapse between 2011 and 2014 participated in an IRB-approved prospective study (11 non-infected; 3 with infected mesh needing excision). Ten-year follow-up data including validated questionnaires (UDI-6, IIQ-7, QoL), pelvic organ prolapse quantifications (POP-Q), complications, re-operations, and secondary prolapses were collected. Paired statistical analyses compared various timepoints and mixed model analysis assessed questionnaire and POP-Q trends over time. ResultsMedian follow-up was 9.7 years (IQR: 6.0 – 0.7) to last POP-Q and 10.4 years (IQR: 9.6 – 11.5) to last contact. No patients were lost to follow-up. Mean baseline C point for all patients was -4.3 and -2.9; 1-year C point was -9.1 and -9.2 and -8.6 and -8.5, respectively at last visit. POP-Q findings improved between pre-PCP and 1-year post surgery and did not significantly change until the last visit. Trends in UDI-6, IIQ-7, QoL and POP-Q findings showed no significant change in any category per year (95% CI, p = 0.2 – 0.9). Secondary anterior compartment prolapse was noted in 3 patients with 1 requiring a repair. ConclusionsPeritoneocolpopexy provides durable vaginal apical support when access to the promontory is compromised. PCP can also be used to prevent secondary prolapse after an infected mesh removal.

Recurrent pelvic prolapse after pelvic organ prolapse suspension (POPS): Analysis and treatment of an emerging clinical issue

ObjectivesTo investigate pelvic organ prolapse (POP) after a novel abdominal prosthetic surgical technique – ‘pelvic organ prolapse suspension’ (POPS) – that has been proposed recently as an easily reproducible laparoscopic technique for the treatment of multicompartmental POP and rectal prolapse. This study also aimed to analyse treatment strategies of recurrent POP after POPS, reporting on anatomical, subjective and functional outcomes following recurrence surgery. MethodsPatients with a symptomatic prolapse relapse after POPS were collected and analysed prospectively at a single tertiary care institution. Each patient was offered a multidisciplinary clinical and radiological evaluation pre-operatively. ResultsTwenty-five women with a median age of 59 [interquartile range (IQR) 49–73] years were enrolled in the study. Of these, 88 % were menopausal. All patients had high-grade (Pelvic Organ Prolapse Quantification System stage > 2) recurrent posterior vaginal wall-predominant prolapse after POPS. Multicompartmental prolapse was found in 64 % of patients. All women complained of vaginal bulging associated with obstructed defaecation syndrome (ODS) symptoms. Surgical treatment consisted of laparoscopic ventral rectopexy (VR) in all 25 cases (100 %), and concomitant sacral colpopexy (SCP) with previous mesh removal in 16 cases (64 %). No anatomical recurrences were observed after median follow-up of 12 (IQR 3–18) months. Overall subjective improvement after surgery was high in all patients (Patient Global Improvement Index ≤ 2). ConclusionsRecurrent POP following POPS appears to predominantly involve the posterior vaginal wall, with associated ODS symptoms. A multidisciplinary approach is advisable for treatment of these patients. Minimally invasive VR alone or in combination with SCP seems to represent an effective treatment.

Evaluating Osteogenic Cell Differentiation Efficacy in the Presence of Polylactide Samples With Varied Compositions for Bone Grafting: In Vitro Study.

In oral implantology, surgeons often confront the need to improve alveolar bone quality and volume before implantation in patients with bone defects. Whereas guided bone regeneration with titanium meshes is a clinical gold standard for bone augmentation, mesh removal pre-implantation presents a drawback. This study explores biodegradable scaffolds as an alternative. The research investigates the impact of various compositions of customized bone-grafting scaffolds on proliferation and osteogenic differentiation processes in vitro. Plates (10 × 10 × 0.5 mm) were fabricated from polylactide (PLA), PLA with 15% hydroxyapatite nanoparticles (PLA/HA), and polylactide with glycolic acid copolymers (PLGA 60:40 and 85:15). Gingival fibroblasts assessed the influence of experimental samples on proliferation and osteogenic differentiation in a low-glucose medium. Osteogenic differentiation was induced, and alizarin red staining measured extracellular matrix calcification via spectrophotometry. Active proliferation of gingival fibroblasts occurred along scaffold edges during cultivation. Although cells proliferated with experimental samples, rates were lower than control cells. PLA/HA showed higher alizarin red staining intensity, indicating enhanced matrix calcification. Experimental samples (PLA, PLA/HA, PLGA 85:15, PLGA 60:40) supported cell proliferation at lower rates than control. PLA/HA demonstrated increased matrix calcification. Biodegradable membranes were nontoxic, suggesting potential for bone augmentation.

Mesh classification and removal terminology

Mesh is a synthetic material used to treat stress urinary incontinence (SUI) and pelvic organ prolapse (POP) in women. There have been several reports by patients of complications around the world and some countries have suspended the use of vaginally inserted mesh for the treatment of SUI and POP due to complications. The aim of this document is to address the types of mesh procedures performed and provide terminology for mesh removal which can be easily understood by health-care providers and patients/consumers, avoiding miscommunication which has been highlighted in the Cumberlege report in the United Kingdom.

72122 - Mesh removal due to foreign body reaction and mesh infection in Groin hernia surgery: A long-term nationwide population-based register study

Initial experience of minimally invasive mesh explantation for inguinodynia.

Chronic pain after minimally invasive inguinal hernia repair with mesh can have debilitating effects on quality of life (QOL), limiting daily activities and ability to work. Many medical and surgical options for treatment have been proposed, however there is no consensus on the role of mesh explantation in the management of these patients. We performed a retrospective review of all patients who underwent groin mesh removal by robotic or laparoscopic approach from July 2012 to July 2023 at our institution. Patients were interviewed post-operatively to determine their overall pain scores and QOL was assessed using the Carolinas Comfort Scale (CCS) Questionnaire. Patient characteristics, operative times, pre-operative imaging techniques and analgesia use was also recorded. Twenty-two patients underwent groin mesh removal for chronic pain, including 12 robotic and 10 laparoscopic operations. The mean pre-operative pain score in all patients was 7.6/10 compared to 4.0/10 post-operatively. The mean post-operative CCS score was 24, indicating moderate discomfort. Four patients demonstrated CCS scores <11 indicating no discomfort and no patients demonstrated CCS scores >90, indicating severe debilitating discomfort. The majority of patients had a reduction or total cessation of analgesia intake post-operatively. Both laparoscopic and robotic mesh explantation for treatment of chronic pain post-inguinal hernia repair is safe and effective in achieving a reduction in pain and reducing the need for long-term analgesia.

The Silent Threat: Unraveling the Rare Catastrophic Complication after Elective Cranioplasty

AbstractAlthough cranioplasty seems to be a simple procedure, fatal complication of development of diffuse severe cerebral edema following cranioplasty although unusual have been reported in a few cases. The mechanism for this occurrence is still speculative. A 38-year-old male patient presented with a history of having undergone left decompressive hemicraniectomy following a road traffic accident with traumatic left intracranial internal carotid artery dissection leading to anterior cerebral artery and middle cerebral artery territory infarct and endovascular embolization of traumatic type 1 left caroticocavernous fistula. The preoperative computed tomography scan of the brain revealed left frontotemperoparietal craniectomy defect with sunken flap and diffuse encephalomalacia with gliosis of the entire left cerebral hemisphere. Immediately following an uneventful cranioplasty surgery with titanium mesh, the patient developed severe hypotension and dilated fixed pupils. Postoperative imaging revealed diffuse severe cerebral edema in bilateral hemispheres with a significant midline shift toward the ipsilateral (left) side, that is, toward the side of cranioplasty. The patient immediately underwent removal of the titanium mesh, and despite all efforts, the patient had a fatal outcome on postoperative day 5. Although this type of fatal complication of diffuse severe cerebral edema is rare in postcranioplasty patients, neurosurgeons must be aware of this complication and close monitoring postprocedure is important, especially in patients with a large craniectomy defect and sunken skin flap.

Surgical training and research in mesh complications

Objective:To review and summarize the peer-reviewed literature for Surgical Training and Research in Mesh Complications. Methods:An international author team reviewed available published literature. Results:This paper reviews the current training situation and recognizes there are no fellowships globally which specifically train in mesh removal/ complications. The UK has recently launched a mesh complications training pathway pilot. New Zealand has recently implemented a credentialing framework for pelvic floor procedures including mesh removal and undertaken national credentialing of surgeons. A proposed training pathway is outlined including training sequence, the training setting, and a modular pathway of training.The authors acknowledge that there is very limited research and evidence for management of mesh complications. Several important research questions are suggested for future research. Future projects for collaborative research are proposed including registries, and development of improved patient education materials for pelvic floor conditions to improve shared decision making.

HERNIA MESH EXPLANTATION FOR MESH INGUINODYNIA AND ALLODYNIA. WHY IS HERNIA MESH SO PAINFUL?

Abstract Introduction Chronic pain after mesh repair for abdominal wall hernia is an indication for the removal of mesh and reconstruction by a non-mesh technique. Materials and Methods In a consecutive series over 19 years, 128 patients had mesh removed to relieve chronic pain. This open method of mesh removal relies on confirming normal anatomical landmarks. The superior and inferior leaf of the External oblique aponeurosis are raised, the spermatic cord is identified and retracted. The mesh is gently dissected off the Internal oblique from lateral to medial, taking care in preserving the vas, and accompanying vessels. Adherent ilio-inguinal, iliohypogastric and genitofemoral nerves are removed with the mesh. The resultant recurrent hernia is repaired by Moloney darn, a tension-free tissue repair. Results 128 consecutive patients have been treated by mesh explantation and immediate reconstruction on average 6 years after implantation. Resolution of symptoms was experienced very shortly after the mesh removed. Preperitoneal mesh particularly Kugel patch has been the most difficult to remove. Meshes have been submitted for histological examination and the findings are usually chronic granulomatous foreign body reaction. Few complications have been encountered with a follow-up period ranging from 6 months to 15 years, the most common being the failure of explantation to alleviate inguinal pain in the long-term. Conclusion All hernia patients should be afforded informed consent including discussing the potential long-term consequences of chronic groin and abdominal pain.
