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

ABSTRACT:

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.

Project description:ImportanceInguinal hernia is the most common general surgical condition in the world. Although task sharing of surgical care with nonsurgeons represents one method to increase access to essential surgery, the safety and outcomes of this strategy are not well described for hernia repair.ObjectiveTo compare outcomes after inguinal hernia repair with mesh performed by medical doctors and surgeons in Ghana.Design, setting, and participantsThis prospective cohort study was conducted from February 15, 2017, to September 17, 2018, at the Volta Regional Hospital in Ho, Ghana. Following successful completion of a training course, 3 medical doctors and 2 surgeons performed inguinal hernia repair with mesh according to the Lichtenstein technique on 242 men with primary, reducible inguinal hernia.Main outcomes and measuresThe primary end point was hernia recurrence at 1 year. The noninferiority limit was set at 5 percentage points. Secondary end points included postoperative complications at 2 weeks and patient satisfaction, pain, and self-assessed health status at 1 year.ResultsTwo-hundred forty-two patients were included; 119 men underwent operations performed by medical doctors and 123 men underwent operations performed by surgeons. Preoperative patient characteristics were similar in both groups. Two-hundred thirty-seven patients (97.9%) were seen at follow-up at 2 weeks, and 223 patients (92.1%) were seen at follow-up at 1 year. The absolute difference in recurrence rate between the medical doctor group (1 [0.9%]) and the surgeon group (3 [2.8%]) was -1.9 (1-tailed 95% CI, -4.8; P < .001), demonstrating noninferiority of the medical doctors. There were no statistically significant differences in postoperative complications (34 [29.1%] vs 29 [24.2%]), patient satisfaction (112 [98.2%] vs 108 [99.1%]), severe chronic pain (1 [0.9%] vs 4 [3.7%]), or self-assessed health (85.9 vs 83.7 of 100) for medical doctors and surgeons.Conclusions and relevanceThis study shows that medical doctors can be trained to perform elective inguinal hernia repair with mesh in men with good results and high patient satisfaction in a low-resource setting. This finding supports surgical task sharing to combat the global burden of hernia disease.
