Am J Surg 2024:S0002-9610(24)00125-9. [PMID: 38519402 DOI: 10.1016/j.amjsurg.2024.02.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/28/2024] [Accepted: 02/15/2024] [Indexed: 03/24/2024]
Abstract
BACKGROUND This systematic review aims to identify genetic and biologic markers associated with abdominal hernia formation. METHODS Following PRIMSA-guidelines, we searched PubMed, MEDLINE, Embase, Scopus, and COCHRANE databases. RESULTS Of 5946 studies, 65 were selected, excluding parastomal hernias due to insufficient data. For inguinal hernias, five studies unveiled 92 susceptible loci across 66 genes, predominantly linked to immune responses. Eleven studies observed elevated MMP-2 levels, with seven highlighting greater MMP-2 in direct compared to indirect inguinal hernias. One incisional hernia study identified unique gene-expression profiles in 174 genes associated with inflammation and cell-adhesion. In hiatal hernias, several genetic risk loci were identified. For all hernia categories, type I/III collagen ratios diminished. CONCLUSIONS Biological markers in inguinal hernias appears consistent. Yet, the genetic predisposition in incisional hernias remains elusive. Further research to elucidate these genetic and biological intricacies can pave the way for more individualized patient care.

Hernia 2020; 24:669-676. [PMID: 31925599 PMCID: PMC7210225 DOI: 10.1007/s10029-019-02116-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Accepted: 12/23/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Synthetic non-resorbable mesh is almost standard in hernia surgery. However, several studies have showed negative effects of permanent implants such as chronic inflammation and complications involving different organs bordering the mesh. Such complications can raise the risk of chronic post-operative pain (CPP). Recently promising results regarding CPP have been published in patients with Lateral Inguinal Hernia (LIH) using a slowly resorbable mesh in Lichtenstein technique. For this reason the aim of the present study was to find the effect of a slowly resorbable implant on the long-term rate of hernia recurrence and chronic post-operative pain in patients with LIH repaired with TEP procedure. METHODS Prospective pilot study of TEP repair using TIGR® Matrix Surgical Mesh in 35 primary LIH. At 3-year follow-up the Visual Analogue Scale (VAS) and the Inguinal Pain Questionnaire were employed to assess pain. Recurrence was determined by ultrasound and clinical examination. RESULTS All patients completed the pain questionnaires but one patient did not attend the planned clinical examination for the 3-year follow-up. No patients had CPP, as defined in the World Guidelines for Groin Hernia Management. Almost all patients had lower VAS score in any activity 3 years following surgery in comparison to the preoperative period. Three patients (8.8%) suffered symptomatic recurrence during the 3-year follow-up. CONCLUSION TEP repair in patients with LIH using a synthetic long-term resorbable mesh was found to be encouraging respecting chronic post-operative pain at 3-year follow-up but at the cost of an increased risk of recurrence.

Abstract
Background The etiology of inguinal hernias remains uncertain even though the lifetime risk of developing an inguinal hernia is 27% for men and 3% for women. The aim was to summarize the evidence on hernia etiology, with focus on differences between lateral and medial hernias. Results Lateral and medial hernias seem to have common as well as different etiologies. A patent processus vaginalis and increased cumulative mechanical exposure are risk factors for lateral hernias. Patients with medial hernias seem to have a more profoundly altered connective tissue architecture and homeostasis compared with patients with lateral hernias. However, connective tissue alteration may play a role in development of both subtypes. Inguinal hernias have a hereditary component with a complex inheritance pattern, and inguinal hernia susceptible genes have been identified that also are involved in connective tissue homeostasis. Conclusion The etiology of lateral and medial hernias are at least partly different, but the final explanations are still lacking on certain areas. Further investigations of inguinal hernia genes may explain the altered connective tissue observed in patients with inguinal hernias. The precise mechanisms why processus vaginalis fails to obliterate in certain patients should also be clarified. Not all patients with a patent processus vaginalis develop a lateral hernia, but increased intraabdominal pressure appears to be a contributing factor.

Abstract
The aim of the present study was to analyze the effect of operating room (OR) care combined with home care on postoperative rehabilitation and prognosis of gastric cancer patients with low PTEN gene expression. Ninety-six gastric cancer patients with low PTEN gene expression, who underwent surgical treatment in our hospital were recruited. PTEN expression was measured by semi-quantitative polymerase chain reaction. Participants were randomized into the observation and control groups, with 48 cases each. Participants in the two groups received the same preoperative examination, gastric cancer surgery, postoperative drug therapy, and general care, while observation group participants were provided more comprehensive OR care combined with home care. After 1 year of home care, the self-rating anxiety scale (SAS) and Hamilton anxiety scale (HAMA) scores, rehabilitation status, overall quality of life, and Family Adaptability and Cohesion Scale were applied to compare postoperative rehabilitation and prognosis status in both groups. Data were statistically analyzed. Patients were followed up for 3 years, and survival time was analyzed. The operative time and bleeding volume between the two groups were not significantly different (p>0.05). The time of extubation and postoperative recovery time in the observation group were shorter than in the control group (p<0.01). The postoperative SAS and HAMA scores in both groups were significantly decreased compared with those preoperatively (p<0.01). Additionally, these scores were significantly lower in the observation than in the control group (p<0.01). The rehabilitation status of body function in the observation group was better than in the control group (p<0.01). Regarding the overall quality of life score and family adaptability and cohesion score, the observation group was better than the control group (p<0.01). In conclusion, OR care combined with home care was effective for the care of gastric cancer patients with low PTEN expression. Improving patient mood and mental state played a positive role in postoperative rehabilitation and prognosis.

Inguinal hernia repair using a synthetic long-term resorbable mesh: results from a 3-year prospective safety and performance study. Hernia 2014; 18:723-30.

Abstract
PURPOSE Conventional meshes for hernia repair and abdominal wall reinforcement are usually made from polypropylene, polyester or other synthetic plastic materials known to promote foreign body reactions and a state of chronic inflammation that may lead to long-term complications. A novel approach is to use long-term resorbable implants like TIGR(®) Matrix Surgical Mesh. Preclinical studies have shown that this mesh maintains mechanical integrity beyond the point in time where newly formed tissue is capable of carrying the abdominal loads. METHODS This was a first-in-man, prospective, pilot study performed during 2009, at two sites in Sweden. Forty patients with primary inguinal hernias were enrolled for Lichtenstein repair using TIGR(®) Matrix Surgical Mesh. The primary endpoint was safety as assessed by monitoring the incidence of adverse events and serious adverse events (SAEs) both related and unrelated to the mesh. The secondary endpoint was pain or discomfort. Visual Analogue Scale (VAS) 0-10 and Inguinal Pain Questionnaire were used for scoring pain and discomfort. Included patients have been followed for 36 months using ultrasound in combination with clinical examination. RESULTS All patients followed a normal early postoperative course. After 12 months no SAEs were reported. None of the patients with an isolated lateral inguinal hernia (LIH) had developed a recurrence but 4 (44 %) with medial and 4 (33 %) with combined hernias had recurred at 36-month follow-up. After 3-year follow-up none of the patients with LIH reported pain in the VAS-form and none of those patients could feel the sensation of a mesh in their groin. In the total study population 5 (16 %) patients experienced chronic pain in the form of mild sporadic pain and 3 (9.7 %) patients could feel the sensation of a mesh in their groin. CONCLUSION The use of a synthetic long-term resorbable mesh (TIGR(®) Matrix Surgical Mesh) in Lichtenstein repair was found to be safe, without recurrences, and promising regarding pain/discomfort at 3-year follow-up in patients with LIH. However, patients with medial and combined inguinal hernias had high recurrence rates.

Abstract
BACKGROUND A defect in collagen metabolism is suspected to be one of the factors responsible for hernia formation. Lysyl oxidase is a copper-dependent enzyme in the process that provides for the structural integrity of collagen molecules, while zinc is essential for tissue maintenance. MATERIALS AND METHODS In a prospective fashion, copper and zinc levels were measured in plasma and tissue specimens obtained from indirect (n=23), direct (n=20) and incisional hernia patients (n=19) and from healthy controls (laparoscopic cholecystectomy patients, n=15) by enzymatic colorimetric analysis. RESULTS Groups were similar in age, comorbid diseases and body mass index. Whereas plasma levels of Cu and Zn in hernia and control patients were similar, and tissue levels were significantly lower in all hernia groups (especially the incisional hernia group) compared to controls (P<0·001). The incisional hernia group had significantly lower tissue copper levels than direct hernia patients and lower zinc levels than indirect hernia patients. CONCLUSIONS Patients with all types of hernia, especially those with incisional hernias, have significantly lower tissue copper and zinc levels than control patients, despite having similar plasma levels. This finding might reflect excessive consumption or dysfunction of lysyl oxidase as playing a role in the aetiology of hernias.

Abstract
BACKGROUND The aetiology and pathogenesis of abdominal wall hernia formation is complex. Optimal treatment of hernias depends on a full understanding of the pathophysiological mechanisms involved in their formation. The aim of this study was to review the literature on specific collagen alterations in abdominal wall hernia formation. METHODS A computer-assisted search of the medical databases PubMed and Embase was performed, together with a cross-reference search of eligible papers. RESULTS Fifty-two papers were included. Collagen alteration depended on the type of hernia; there were more pronounced changes in patients with a direct inguinal hernia than in those with an indirect inguinal hernia, recurrent inguinal hernia or incisional hernia. A consistent finding was a significant increase in immature type III collagen relative to the stronger type I collagen in patients with a hernia. This resulted in thinner collagen fibres with a correspondingly diminished biomechanical strength. It has been suggested that these alterations are due to variation in the synthesis, maturation or degradation of collagen by matrix metalloproteinases, in combination or alone. CONCLUSION Hernia formation and recurrence is associated with altered collagen metabolism manifested by a decreased type I:III collagen ratio.

Abstract
OBJECTIVE The aetiology of inguinal hernia involves changes in collagen turnover and metalloproteinase expression; yet it is not known whether the elastic fibre system could also be affected. This study was designed to compare the expression of tropoelastin (TE), lysyl oxidase-like 1 (LOXL-1) and elastase in the transversalis fascia of patients with and without inguinal hernia. MATERIAL AND METHODS Transversalis fascia (TF) specimens were obtained from patients undergoing surgery for direct or indirect inguinal hernia (n = 20 each) and from multi-organ donors during organ procurement (controls, n = 16). The specimens were divided according to age (20-40/41-60 years). Tissues were immunohistochemically labelled using anti-tropoelastin, anti-LOXL-1 and anti-elastase antibodies and subjected to Western blot analysis. Relative amounts of LOXL-1 and TE mRNA were determined by real time RT-PCR in cultured cells obtained from the TF of patients and controls. RESULTS Significantly lower TE and LOXL-1 levels were observed in patients with direct inguinal hernia compared with controls or those with indirect hernia. In contrast, patients with direct inguinal hernia showed significantly higher elastase expression. In fibroblasts isolated from the TF, relative amounts of tropoelastin mRNA were lower for the hernia groups but differences were not significant. LOXL-1 mRNA levels were significantly lower in the direct hernia group compared to controls. CONCLUSIONS Our findings suggest that impaired elastic fibre function in the transversalis fascia of patients with direct inguinal hernia, reflected by diminished elastin synthesis and its enhanced enzyme degradation, contributes to the development of this type of hernia.

Abstract
Incidence curves for the development of inguinal hernia disease and recurrences thereof exhibit a linear rise over the years and therefore suggest multi-factorial underlying causes. Several studies have revealed marked changes in the abundance and composition of interstitial collagens in patients with (recurrent) hernia diseases, adult groin hernia and incisional hernia. These observations led to the hypothesis that hernia formation and the recurrence of incisional hernia may be explained by disordered tissue renewal and by abnormal wound healing, respectively. Interstitial collagens, owing to their long half-lives and biomechanical strength, are most likely critical components of the biological system of tissue remodelling. An overview of the literature is provided, and the consequences for surgical practice are discussed.
