“…Their results showed that the tensile strength ranged between 12.8 and 23.2 N/cm, which are comparable to the values found in the present study where the values of break stress were 27.5 ± 3.5 and 22.0 ± 1.74 N/cm for LCM1 and LCM2, respectively. Another example of low-cost meshes successfully used for hernia repair is represented by the polyester mosquito mesh implanted in the study of Rouet, Bwelle [ 20 ] which had a tensile stress of 20 N/cm. Furthermore, Sanders, Kingsnorth [ 9 ] compared the polyethylene mosquito mesh which was used by the non-profit organization “Operation Hernia” with some common commercial meshes.…”

Purpose Low-cost meshes (LCM) were repurposed for the repair of hernias in the developing world. In vivo studies have shown LCM to have comparable results to commercial meshes (CM) at a fraction of the cost. However, little has been done to characterise the mechanical and biocompatible properties of LCM, preventing its clinical use in the UK. The objectives of the research are to assess mechanical and ultrastructural properties of two UK-sourced low-cost meshes (LCM) and the characterisation of the LCMs in vitro biocompatibility. Methods Mechanical properties of the two LCM were measured through uniaxial tensile test and ultrastructure was evaluated with Scanning Electron Microscopy. LIVE/DEAD® Viability/Cytotoxicity Assay kit and alamarBlue were used to assess cellular viability and proliferation, respectively. Images were acquired with a fluorescence microscope and analysed using ImageJ (NIH, USA). Results LCM1 and LCM2 were both multifilament meshes, with the first having smaller pores than the latter. LCM1 exhibited significantly higher tensile strength (p < 0.05) than LCM2 but significantly lower extensibility (p < 0.0001), while Young’s Modulus of the two samples was not significantly different. No significant difference was found in the cellular viability and morphology cultured in LCM1 and LCM2 conditioned media. Metabolic assay and fluorescence imaging showed cellular attachment and proliferation on both LCMs over 14 days. Conclusion The characterisation of the two UK-sourced LCMs showed in vitro biocompatibility and mechanical and ultrastructural properties comparable to the equivalent CM. This in vitro data represents a step forward for the feasibility of adopting LCM for surgical repair of hernias in the UK.

“…A total of 139 records were found through database searching. Following application of data exclusion criteria, nine studies were finally included (3 RCTs, 1 non‐RCT and 5 studies using prospectively developed databases). All studies took place in LEDCs, two in the Indian subcontinent and seven in Africa.…”

“…Data from the nine studies were extracted to form an aggregate quantitative synthesis including a total cohort of 1360 patients (1085 patients in the MNM intervention and 275 in the CSM control group). The mean age of participants in the studies ranged from 33 to 52 years, and the mean length of follow‐up varied from 1 month to 5 years ( Tables S1 and S2 , supporting information).…”

Meta-analysis of the use of sterilized mosquito net mesh for inguinal hernia repair in less economically developed countries

Background Inguinal hernias are common in less economically developed countries (LEDCs), and associated with significant morbidity and mortality. Tension‐free mesh repair is the standard treatment worldwide. Lack of resources combined with the high cost of commercial synthetic mesh (CSM) have limited its use in LEDCs. Sterilized mosquito net mesh (MNM) has emerged as a low‐cost, readily available alternative to CSM. The aim of this systematic review and meta‐analysis was to evaluate the safety and efficacy of MNM for the use in hernia repair in LEDCs. Methods A systematic review and data meta‐analysis of all published articles from inception to August 2018 was performed. Cochrane Central Register of Controlled Trials, MEDLINE and Embase databases were searched. The primary outcome measure was the overall postoperative complication rate of hernia repair when using MNM. Secondary outcome measures were comparisons between MNM and CSM with regard to overall complication rate, wound infection, chronic pain and haematoma formation. Results A total of nine studies were considered relevant (3 RCTs, 1 non‐randomized trial and 5 prospective studies), providing a total cohort of 1085 patients using MNM. The overall complication rate for hernia repair using MNM was 9·3 per cent. There was no significant difference between MNM and CSM regarding the overall postoperative complication rate (odds ratio 0·99, 95 per cent c.i. 0·65 to 1·53; P = 0·98), severe or chronic pain (OR 2·52, 0·36 to 17·42; P = 0·35), infection (OR 0·56, 0·19 to 1·61; P = 0·28) or haematoma (OR 1·05, 0·62 to 1·78; P = 0·86). Conclusion MNM has a low overall postoperative complication rate and is unlikely to be inferior to CSM in terms of safety and efficacy. MNM is a suitable low‐cost alternative to CSM in the presence of financial constraint.

“…Use of sterilized mosquito net mesh (MNM) as an alternative prosthesis is increasingly considered as a valid treatment option for hernias in countries with limited resources [8]. This innovative approach permits the use of modern techniques in countries without universal health coverage, where most patients are cash payers These alternative prostheses are increasingly used in many African countries with the spread of Lichtenstein's technique [8,9,10]. With the advent of laparoscopy in Africa, we aimed at evaluating the use of MNM in laparoscopic hernia repair, in terms of clinical and economic outcomes, particularly in underserved rural areas.…”
