Five-year results of a randomised controlled multi-centre study comparing heavy-weight knitted versus low-weight, non-woven polypropylene implants in Lichtenstein hernioplasty
Abstract:BackgroundThis prospective randomised study evaluated whether non-knitted and non-woven lightweight implants can influence postoperative pain and time of return to normal activity, without increasing the recurrence rate in Lichtenstein inguinal hernioplasty.MethodsPatients were operated on in four centres, randomised blindly into two groups with respect to the mesh used: Surgimesh WN (non-woven polypropylene microfibre sheet) and heavy weight polypropylene mesh. The operation was performed according to the Lic… Show more
“…foreign body sensation and chronic pain are reduced. Patients report less consumption of analgesics at the early postoperative period, quicker ambulation and return to work [10].…”
Abdominal wall hernia correction is one of the most common surgical procedures. 85,000 hernia operations are performed in Poland each year. Modern techniques of abdominal wall reconstruction utilize surgical implants for fascial defect closure. In the 70s and the 80s of the last century, these techniques gained widespread acceptance among surgeons. Significant improvement of results in terms of recurrences was observed. Treatment of large abdominal wall defects became possible. Three types of surgical implants were developed early: polipropylene (PP), poliethylene (PE) and politetrafluoroethylene (PTfE). Unfortunately, negative effects of implanted material soon became apparent. Excessive native tissues inflammatory response to the implanted material, leading to multiple complications was observed. Recurrences due to fibrosis, chronic regional pain, stiffness of the operation site, intestinal adhesions and fistulas, infertility and infections were reported. In some cases the use of standard synthetic implant was contraindicated. Analyzing drawbacks of the standard hernia implants, the medical industry developed new materials to improve treatment results. The most popular, currently utilized synthetic materials, are presented in this review in the context of clinical results (Adv Clin Exp Med 2014, 23, 1, 135-142).

“…However, among these studies, 33 different validated instruments were identified (tables 4, 5, 6) [11,13,14,17,19,21,26,28,29,32,36,38,41,43,45,47,48,51,53,56,57,58,59,60,61,62,63,64,65,79,90]. …”

“…First, there was heterogeneity in the postoperative time period after which pain was classified as chronic. This ‘chronic' time frame ranged between 1 and 36 months [63,64,65,66,67]. Second, some studies included the quantitative factor PI in their definition of CPIP, which was either expressed using descriptive terms [68,69,70,71,72,73,74,75], a visual analog scale (VAS) score, or a QOL score [31,76,77,78,79,80,81,82,83,84,85].…”
Background: Chronic postoperative inguinal pain (CPIP) is the most common long-term complication of inguinal hernia repair. As such procedures are routinely performed, CPIP can be considered a significant burden to global health care. Therefore, adequate preventative measures relevant to surgical practice are investigated. However, as no gold standard research approach is currently available, study and outcome measures differ between studies. The current review aims to provide a qualitative analysis of the literature to seek out if outcomes of CPIP are valid and comparable, facilitating recommendations on the best approach to preventing CPIP. Methods: A systematic review of recent studies investigating CPIP was performed, comprising studies published in 2007-2015. Study designs were analyzed regarding the CPIP definitions applied, the use of validated instruments, the availability of a baseline score, and the existence of a minimal follow-up of 12 months. Results: Eighty eligible studies were included. In 48 studies, 22 different definitions of CPIP were identified, of which the definition provided by the International Association for the Study of Pain was applied most often. Of the studies included, 53 (66%) used 33 different validated instruments to quantify CPIP. There were 32 studies (40%) that assessed both pain intensity (PI) and quality of life (QOL) with validated tools, 41% and 4% had a validated assessment of only PI or QOL, respectively, and 15% lacked a validated assessment. The visual analog scale and the Short Form 36 (SF36) were most commonly used for measuring PI (73%) and QOL (19%). Assessment of CPIP was unclear in 15% of the studies included. A baseline score was assessed in 45% of the studies, and 75% had a follow-up of at least 12 months. Conclusion: The current literature addressing CPIP after inguinal hernia repair has a variable degree of quality and lacks uniformity in outcome measures. Proper comparison of the study results to provide conclusive recommendations for preventive measures against CPIP therefore remains difficult. These findings reaffirm the need for a uniform and validated assessment with uniform reporting of outcomes to improve the burden that CPIP poses to a significant surgical patient population.
“…Tension-free repair with non-absorbable mesh (polypropylene) has been used in a higher number of cases during the past few years. 4 When meshes are categorized by density, a mesh with density >100g/m 2 is accepted as heavy, whereas a 35-50g/m 2 density is classified as lightweight. Several recent controlled clinical studies have suggested that lightweight meshes may improve patient comfort.…”
Background: Inguinal hernia repair is one of the most common surgical procedures performed in practice. Although numerous techniques have been described, currently tension free mesh repair is the standard of care in the treatment of hernias because of the low recurrence rates.Methods: A comparative study between Light and Heavy Polypropylene mesh in Lichtenstein repair of inguinal hernia was conducted at Department of General Surgery in MVJ Medical college and Research Hospital, Hoskote, Bangalore on patients admitted in Department of General Surgery between November 2014 to July 2016 undergoing Lichtenstein tension free mesh repair for inguinal hernia. The study is a prospective study. 30 Patients were in Light mesh group and 30 were in Heavy mesh group.Results: Age group of 31-40 yrs had highest incidence of inguinal hernia. Males outnumber Females in incidence of Inguinal Hernia. Foreign body sensation in Heavy mesh group is significantly high. Average of 26.7% of the patients had foreign body sensation in Heavy mesh group. Whereas in Light group average was 10%. Chronic pain also showed significant readings in Heavy mesh group. Stiffness over abdominal wall was complained by 10% of patients overall in the light mesh group whereas no patients had this complaint in light mesh group. Recurrence was high in light mesh group where total of 5 patients had recurrence and in heavy there were only 2 patients with recurrence.Conclusions: In my study light mesh has been proved to be better than heavy mesh in treatment of inguinal hernia.
