Open Med (Wars) 2024; 19:20230887. [PMID: 38221930 PMCID: PMC10787303 DOI: 10.1515/med-2023-0887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 12/01/2023] [Accepted: 12/07/2023] [Indexed: 01/16/2024] Open
Abstract
Infection following inguinal hernia repair (IHR) is uncommon. Rational use of antibiotics can significantly improve the prognosis of patients. However, accurately identifying the pathogen involved is usually challenging. This case report describes a patient who developed intermittent fever after undergoing open preperitoneal tension-free repair of a bilateral inguinal hernia. The scrotal fluid specimen was cultured and subjected to metagenomic next-generation sequencing (mNGS). Culture revealed the presence of Enterococcus faecalis (a facultative anaerobe). However, mNGS detected E. faecalis along with multiple anaerobic bacteria including Bacteroides thetaiotaomicron, Parabacteroides distasonis, and Levyella massiliensis. The patient was finally diagnosed with a mixed infection of E. faecalis and multiple anaerobes, and his condition was effectively controlled after timely adjustment of the antibiotic regimen. Treating postoperative infections with multiple concurrent conditions can be challenging. mNGS is valuable for the accurate diagnosis and treatment of infections, as it not only can further verify the culture results, but also assist clinicians in ruling out pulmonary infection caused by hematogenous dissemination after IHR in patients.

Abstract
INTRODUCTION The use of prosthetic mesh in hernia repair provides a powerful tool to increase repair longevity, decrease recurrence rates, and facilitate complex abdominal wall reconstruction. Overall infection rates with mesh are low, but for those affected there is high morbidity and economic cost. The availability of a practicable small animal model would be advantageous for the preclinical testing of prophylactics, therapeutics, and new biomaterials. To this end, we have developed a novel mouse model for implantation of methicillin-resistant Staphylococcus aureus-infected surgical mesh and provide results from antibiotic and immunotherapeutic testing. MATERIALS AND METHODS Implantation of surgical mesh between fascial planes of the mouse hind limb was used to approximate hernia repair in humans. Surgical mesh was inoculated with methicillin-resistant Staphylococcus aureus to test the efficacy of antibiotic therapy with daptomycin and/or immunotherapy to induce macrophage phagocytosis using antibody blockade of the CD47 "don't eat me" molecule. Clinical outcomes were assessed by daily ambulation scores of the animals and by enumeration of mesh-associated bacteria at predetermined end points. RESULTS A single prophylactic treatment with daptomycin at the time of surgery led to improved ambulation scores and undetectable levels of bacteria in seven of eight mice by 21 days postinfection. Anti-CD47, an activator of macrophage phagocytosis, was ineffective when administered alone or in combination with daptomycin treatment. Ten days of daily antibiotic therapy begun 3 days after infection was ineffective at clearing infection. CONCLUSIONS This fast and simple model allows rapid in vivo testing of novel antimicrobials and immunomodulators to treat surgical implant infections.

Abstract
This report aims to discuss a case of asymptomatic mesh infection 6 years after laparoscopic totally extraperitoneal (TEP) inguinal hernia repair and to reveal that the risk of mesh infection may occur after a long period of this surgery. This report is also intended to suggest surgeons pay more attention to the follow‐up of such patients and to be aware of the possibility of mesh infection to assist in early diagnosis and treatment. A 63‐year‐old male patient, who underwent TEP inguinal hernia repair 6 years ago for right inguinal hernia, fell down accidentally 2 weeks ago. Enhanced computed tomography(CT) showed right lower abdomen cystic lesions, so he underwent laparoscopic surgery during which abscess caused by delayed mesh infection was found. After removing the mesh and abscess, he was discharged. The risk of mesh infection after TEP inguinal hernia repair is low, but it can last for more than 6 years and can even be asymptomatic as long as the mesh remains in the body.

Abstract
OBJECTIVE The role of antibiotic prophylaxis (AP) in the prevention of surgical site infection (SSI) after hernia repair is debated. We conducted this systematic review and meta-analysis to assess the evidence on the value of prophylactic antibiotics in reducing the risks of SSI after open hernia surgery. METHODS We ran an online and manual search to identify relevant randomized controlled trials that compared prophylactic antibiotics to nonantibiotic controls in patients undergoing open surgical hernia repair. Data on SSI risk were extracted and pooled as risk ratios (RRs) with 95% confidence intervals (95% CIs), using RevMan software. We further used the Cochrane risk of bias tool and GRADE assessment to evaluate the quality of generated evidence. RESULTS Twenty-nine studies (N = 8,616 patients) were included in the current analysis. Antibiotic prophylaxis reduced the risk of SSI in open hernia repair patients (RR = 0.65, 95% CI = 0.53, 0.79). Subgroup analysis showed a significant benefit for antibiotics in mesh repair patients (RR = 0.60, 95% CI = 0.48, 0.76) yet no significant difference in SSI risk after herniorrhaphy (RR = 0.86, 95% CI = 0.54, 1.36). In addition, AP was associated with a significant reduction in superficial SSI risk (RR = 0.56, 95% CI = 0.43, 0.72) but not deep SSI (RR = 0.70, 95% CI = 0.30, 1.62). Further analysis showed a significant reduction in SSI risk with amoxicillin/clavulanic acid and cefazolin but not with cefuroxime. CONCLUSION The present meta-analysis suggests that AP is beneficial prior to open mesh hernia repair. However, the quality of evidence was low, and further well-designed trials are needed.

Abstract
BACKGROUND Inguinal or femoral hernia is a tissue protrusion in the groin region and has a cumulative incidence of 27% in adult men and of 3% in adult women. As most hernias become symptomatic over time, groin hernia repair is one of the most frequently performed surgical procedures worldwide. This type of surgery is considered 'clean' surgery with wound infection rates expected to be lower than 5%. For clean surgical procedures, antibiotic prophylaxis is not generally recommended. However after the introduction of mesh-based hernia repair and the publication of studies that have high wound infection rates the debate as to whether antibiotic prophylaxis is required to prevent postoperative wound infections started again. OBJECTIVES To determine the effectiveness of antibiotic prophylaxis in reducing postoperative (superficial and deep) wound infections in elective open inguinal and femoral hernia repair. SEARCH METHODS We searched several electronic databases: Cochrane Registry of Studies Online, MEDLINE Ovid, Embase Ovid, Scopus and Science Citation Index (search performed on 12 November 2019). We also searched two trial registers and the reference list of included studies. SELECTION CRITERIA We included randomised controlled trials comparing any type of antibiotic prophylaxis versus placebo or no treatment for preventing postoperative wound infections in adults undergoing inguinal or femoral open hernia repair surgery (tissue repair and mesh repair). DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted data and assessed risk of bias. We separately analysed results for two different surgical methods (herniorrhaphy and hernioplasty). Several studies revealed infection rates that were higher than the expected 5% for clean surgery and we therefore divided studies into two subgroups: high infection risk environments (≥ 5% infection rate); and low infection risk environments (< 5% infection rate). We performed meta-analyses with random-effects models. We analysed three outcomes: superficial surgical site infections (SSSI); deep surgical site infections (DSSI); and all postoperative wound infections (SSSI + DSSI). MAIN RESULTS In this review update we identified and included 10 new studies. In total, we included 27 studies with 8308 participants in this review. It is uncertain whether antibiotic prophylaxis as compared to placebo (or no treatment) prevents all types of postoperative wound infections after herniorrhaphy surgery (risk ratio (RR) 0.86, 95% confidence interval (CI) 0.56 to 1.33; 5 studies, 1865 participants; very low quality evidence). Subgroup analysis did not change these results. We could not perform meta-analyses for SSSI or DSSI as these outcomes were not reported separately. Twenty-two studies related to hernioplasty surgery (total of 6443 participants) and we analysed three outcomes: SSSI; DSSI; SSSI + DSSI. Within the low infection risk environment subgroup, antibiotic prophylaxis as compared to placebo probably makes little or no difference for the outcomes 'prevention of all wound infections' (RR 0.71, 95% CI 0.44 to 1.14; moderate-quality evidence) and 'prevention of SSSI' (RR 0.71, 95% CI 0.44 to 1.17, moderate-quality evidence). Within the high infection risk environment subgroup it is uncertain whether antibiotic prophylaxis reduces all types of wound infections (RR 0.58, 95% CI 0.43 to 0.77, very low quality evidence) or SSSI (RR 0.56, 95% CI 0.41 to 0.77, very low quality evidence). When combining participants from both subgroups, antibiotic prophylaxis as compared to placebo probably reduces the risk of all types of wound infections (RR 0.61, 95% CI 0.48 to 0.78) and SSSI (RR 0.60, 95% CI 0.46 to 0.78; moderate-quality evidence). Antibiotic prophylaxis as compared to placebo probably makes little or no difference in reducing the risk of postoperative DSSI (RR 0.65, 95% CI 0.26 to 1.65; moderate-quality evidence), both in a low infection risk environment (RR 0.67, 95% CI 0.11 to 4.13; moderate-quality evidence) and in the high infection risk environment (RR 0.64, 95% CI 0.22 to 1.89; low-quality evidence). AUTHORS' CONCLUSIONS Evidence of very low quality shows that it is uncertain whether antibiotic prophylaxis reduces the risk of postoperative wound infections after herniorrhaphy surgery. Evidence of moderate quality shows that antibiotic prophylaxis probably makes little or no difference in preventing wound infections (i.e. all wound infections, SSSI or DSSI) after hernioplasty surgery in a low infection risk environment. Evidence of low quality shows that antibiotic prophylaxis in a high-risk environment may reduce the risk of all wound infections and SSSI, while evidence of very low quality shows that it is uncertain whether antibiotic prophylaxis reduces DSSI after hernioplasty surgery.

Abstract
PURPOSE Antibiotic prophylaxis in inguinal hernia repair (IHR) is contentious in literature and practice. In low-risk patients, for whom evidence suggests antibiotic prophylaxis is unnecessary, many surgeons still advocate for its routine use. This study surveys prescription patterns of Department of Defense (DoD) general surgeons. METHODS An anonymous survey was sent electronically to approximately 350 DoD general surgeons. The survey asked multiple-choice and free text answers about prescribing patterns and knowledge of current evidence for low-risk patients undergoing elective open inguinal hernia repair without mesh (OIHRWOM), open inguinal hernia repair with mesh (OIHRWM), or laparoscopic inguinal hernia repair (LIHR). RESULTS 110 DoD general surgeons consented to participate. 58.6, 95 and 84.2% of surgeons always administer antibiotic prophylaxis in OIHRWOM, OIHRWM, and LIHR, respectively. 37.9, 70.9, and 63.2% of surgeons believe that it reduces rates of surgical site infection in OIHRWOM, OIHRWM, and LIHR, respectively. The most common reasons for empirically prescribing antibiotic prophylaxis include "I think the evidence supports it" (27 of 72 responses), "I would rather be conservative and safe" (15 of 72 responses), and "I am following my hospital/department guidelines" (9 of 72 responses). 11.8, 40.8, and 32.9% of surgeons believe current evidence supports antibiotic prophylaxis use in OIHRWM, OIHRWOM, and LIHR, respectively. 50, 18.4, and 22.4% of surgeons believe current evidence refutes antibiotic prophylaxis use in OIHRWM, OIHRWOM, and LIHR, respectively. CONCLUSION The survey results indicate that the majority of practicing DoD general surgeons still empirically prescribe surgical antibiotic prophylaxis in IHR despite more conflicting opinions that it has no meaningful effect or that current evidence does not supports its use.

Abstract
INTRODUCTION Despite being one of the most commonly performed general surgery procedures, surgical site infection (SSI) is still seen in primary, elective, open inguinal hernia repair. Studies have reported a wide range of infection rates, yet predictive risk factors have not been definitely identified leading to variability and controversy in the use of pre-operative antibiotics. In this study, the authors seek to identify factors predictive of SSI development in a large cohort of patients undergoing initial unilateral open inguinal repair. METHODS The American College of Surgery National Surgical Quality Improvement Program (ACS NSQIP) personal use file (PUF) database was queried for initial, open, reducible inguinal hernia repair cases in adults with clean surgical sites performed from 2012 to 2015 (CPT 49,505 and class one wound). Patient data were analyzed using univariate and multivariate analysis to identify factors predictive of surgical site infection. RESULTS 57,951 cases were identified. 90.8% were men with an average age of 58.2 years and a median operative time of 53.0 min. Of all variables evaluated with univariate logistic regression, 17 demonstrated an association with surgical site infection. Performing multiple logistic regression on those 17 variables yielded 3 factors independently associated with surgical site infection: diabetes (OR 2.017, 95% CI 1.012-4.023), BMI ≥ 35 kg/m2 (OR 2.587, 95% CI 1.123-5.964), and current smoking (OR 2.071, 95% CI 1.126-3.811). CONCLUSION Diabetes, BMI ≥ 35 kg/m2, and current smoking are significantly associated with an increased odds surgical site infection after initial, open, reducible inguinal hernia repair in adults with clean surgical sites.

Abstract
PURPOSE Africa's inguinal hernia burden is high with large numbers of untreated hernias. Mesh repair is recommended in developed countries, but the best repair in developing countries is unknown. Little is known about knowledge and practice of surgeons in Nigeria performing inguinal hernia repair. Surgical trainees can provide this information. METHODS A questionnaire-based survey was administered to surgical trainees from all over Nigeria who had attended the West African College of Surgeons' integrated revision course in Jos, on their practice and recommendations concerning elective inguinal hernia repair. RESULTS One hundred and nine surgical trainees (90.8%) consisting of 78 (71.6%) registrars and 30 (27.5%) senior registrars responded. Thirty-two (29.4%) used antibiotics routinely for inguinal hernia surgery. Ceftriaxone was the most widely used antibiotic (45%). Ninety-two (84.4%) respondents will perform this surgery as day case. Forty (36.7%) respondents stated modified Bassini repair as their preferred method of repair. Mesh repair was recommended by 93 (85.3%) respondents while 65 of 100 respondents (65%) recommended laparoscopic surgery. Of 103 respondents, 93 (90.3%) had performed inguinal hernia repair and 34 (33%), mesh repair. For 56 (51.4%) respondents, the most difficult part of open hernia surgery was sac dissection. CONCLUSIONS Surgical trainees in Nigeria perform more tissue-based inguinal hernia repair than mesh but majority would recommend both mesh repair and laparoscopic surgery. Majority found sac dissection as the most difficult part of open hernia surgery.

Abstract
PURPOSE The use of prophylactic antibiotics in the mesh repair of inguinal hernias remains controversial. The aim of this study was to determine the perception of surgeons about surgical site infection and how this affects their clinical practice. METHODS A SurveyMonkey of general surgeons and senior surgical trainees was conducted via the local trust network and the questionnaire was displayed on the website of the Association of Surgeons of Great Britain and Ireland and Association of Surgeons in Training. RESULTS Eighty-one responses were received from surgeons who perform an average of 75 hernia repairs per year - the majority by open technique. Thirty-six (44.4%) used routine antibiotic prophylaxis, 40 (49.4%) selectively, and five (6.2%) not at all as the five surgeons who did not use antibiotics perceived their surgical site infection rate to be <1% and have never removed an infected mesh from a hernia wound. There was no clear difference between those who use prophylactic antibiotics routinely or selectively as the experience of mesh explantation is similar (56% versus 55% had 2-10 meshes removed respectively). Seventy-seven (95%) of surgeons felt a new specific set of guidelines was required. CONCLUSION This study highlights the fact that in the absence of clear guidelines, most surgeons base their use of prophylactic antibiotics on their perceived risk or experience of surgical site infection. There is a strong need for a new set of guidelines to address the use of prophylactic antibiotics in groin hernia surgery.

Abstract
BACKGROUND First-generation cephalosporins (such as cefazolin) are recommended as antibiotic prophylaxis in groin hernia repair, but other broad-spectrum antibiotics have also been prescribed in clinical practice. This was a systematic review and network meta-analysis to compare the efficacy of different antibiotic classes for prevention of surgical-site infection (SSI) after hernia repair. METHODS RCTs were identified that compared efficacy of antibiotic prophylaxis on SSI after inguinal or femoral hernia repair from PubMed and Scopus databases up to March 2016. Data were extracted independently by two reviewers. Network meta-analysis was applied to assess treatment efficacy. The probability of being the best antibiotic prophylaxis was estimated using surface under the cumulative ranking curve (SUCRA) analysis. RESULTS Fifteen RCTs (5159 patients) met the inclusion criteria. Interventions were first-generation (7 RCTs, 1237 patients) and second-generation (2 RCTs, 532) cephalosporins, β-lactam/β-lactamase inhibitors (6 RCTs, 619) and fluoroquinolones (2 RCTs, 581), with placebo as the most common comparator (14 RCTs, 2190). A network meta-analysis showed that β-lactam/β-lactamase inhibitors and first-generation cephalosporins were significantly superior to placebo, with a pooled risk ratio of 0·44 (95 per cent c.i. 0·25 to 0·75) and 0·62 (0·42 to 0·92) respectively. However, none of the antibiotic classes was significantly different from the others. SUCRA results indicated that β-lactam/β-lactamase inhibitors and first-generation cephalosporins were ranked first and second respectively for best prophylaxis. CONCLUSION β-Lactam/β-lactamase inhibitors followed by first-generation cephalosporins ranked as the most effective SSI prophylaxis for adult patients undergoing groin hernia repair.

Zhuo Y, Zhang Q, Tang D, Cai D. The effectiveness of i.v. cefuroxime prophylaxis of surgical site infection after elective inguinal hernia repair with mesh: A retrospective observational study. Eur J Clin Pharmacol 2016; 72:1033-9. [PMID: 27165663 DOI: 10.1007/s00228-016-2067-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2016] [Accepted: 04/27/2016] [Indexed: 02/05/2023]
Abstract
PURPOSE The efficacy of routine antibiotic prophylaxis for prevention of surgical site infection (SSI) after elective inguinal hernia repair with a mesh patch remains uncertain. The authors of a recent Cochrane meta-analysis based on 17 randomized trials were unable to draw a definitive conclusion on this subject. The purpose of this study was to determine the effectiveness of prophylactic antibiotics for prevention of SSI after elective inguinal hernia repair with mesh and the risk factors for SSI. METHODS All low-risk patients who underwent elective inguinal hernia repair with mesh at our institution between 2010 and 2015 were enrolled in this study, with the exception of patients with recurrent hernias or immunosuppressive diseases. All patients received a single intravenous (i.v.) injection of cefuroxime (1.5 g) within 2 h prior to surgery at the discretion of the surgeon. SSI was defined using criteria of the Centers for Disease Control and Prevention. The variables which could influence the rate of SSI were analyzed by multivariate analysis to determine the independent risk factors for SSI. RESULTS Among the 605 patients who underwent elective inguinal hernia repair with mesh during the study period, 553 were eligible for enrolment in the study. Of these, 331 received a single dose of cefuroxime preoperatively. The overall SSI rate was 5.4 %; 9.4 % of those patients who did not receive preoperative antibiotic prophylaxis developed SSI versus 2.8 % of those who did receive prophylaxis (P = 0.001). All infections were superficial. Factors independently associated with SSI were advanced age, smoking and preoperative stay. CONCLUSIONS The incidence of SSI among low-risk patients who did and did not receive preoperative antibiotic prophylaxis after elective inguinal hernia repair with mesh differed significantly, particularly among patients of advanced age, smokers and patients with a prolonged preoperative stay in the hospital.

Abstract
The purpose of this systematic review is to provide an “up-to-date” evidence-based guideline and clarify the possible benefits as well as drawbacks of local anesthesia (LA) and general anesthesia (GA) in open inguinal hernia surgery in adults. Study method comprised randomized controlled trials. Primary outcome measures were complications, pain control, and patient recovery. Secondary outcome measures were patient satisfaction and hernia recurrence. A total of 14 randomized controlled trials contributed to the study. A total of 1677 patients were analyzed, with 953 in the LA group and 724 in the GA group. Complications were statistically less frequent in the LA group compared with the GA group [odds ratio (OR), 0.31; 95% confidence interval (95% CI), 0.15, 0.64). Supplemental intraoperative analgesia had a statistical significance in the LA group, with an OR of 28.93 (95% CI, 7.86, 106.47). Postoperative pain was statistically significantly lower in the LA group [standardized eman difference (SMD), −1.06; 95% CI, −1.64, −0.48)]. Length of stay was shorter for patients who underwent operation under LA compared with those receiving GA (OR, −1.21; 95% CI, −2.08, −0.33]). Time to full mobility was shorter in the LA group, without statistical significance (OR, 3.04; 95% CI, 0.19, 47.90), whereas measuring in SMD showed significance in comparison with GA (SMD, −1.74; 95% CI, −2.34, −1.14). Hernia recurrence was not noted. Patient satisfaction was greater in the LA group (SMD, 0.65; 95% CI, 0.15, 1.15). Compared with GA, LA showed superiority in terms of complications, postoperative pain, length of stay, time to full mobility, and patient satisfaction. Therefore, it appears to be a more appropriate anesthetic technique for open inguinal hernia repair in adults.

Abstract
OBJECTIVE To investigate the clinical effect of fast-track surgery combined with Chinese medicine treatment in devascularization operation for cirrhotic esophageal varices. METHODS Seventy-two patients with cirrhotic esophageal varices were selected from January 2009 to June 2013, and randomly assigned to a conventional group and a fast-track group (fast-track surgery combined with Chinese medicine treatment) using a randomized digital table, 36 cases in each group. Operation and anesthesia recovery time, postoperative hospitalization and quality of life were recorded and compared between groups during the perioperative period. RESULTS Compared with the conventional group, the fast-track group had longer operation time (253.6±46.4 min vs. 220.6±51.0 min) and anesthesia recovery time (50.5±15.9 min vs. 23.5±9.6 min; P<0.01); less bleeding (311.3±46.8 mL vs. 356.2±57.5 mL; P<0.01) and less transfusion (1932.3±106.9 mL vs. 2045.6±115.4 mL; P<0.01); as well as faster recovery of gastrointestinal function, shorter postoperative hospitalization and higher quality of life. There were no serious postoperative complications and no further bleeding occurred. CONCLUSION Fast-track surgery combined with Chinese medicine treatment is a safe and feasible approach to accelerate the recovery of patients with cirrhotic portal hypertension in perioperative period of devascularization operation.

Results of the Herniamed Registry. Surg Endosc 2015; 29:3741-9. [PMID: 25786905 PMCID: PMC4648957 DOI: 10.1007/s00464-015-4149-2] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2014] [Accepted: 02/06/2015] [Indexed: 11/29/2022]
Abstract
Introduction The use of antibiotic prophylaxis in inguinal hernia repair is a controversial issue. Accepted randomized controlled trials or registry data with specific analysis of endoscopic repaired patients do not exist. Patient and methods The data presented in this study compared the prospectively collected data from the Herniamed Registry on all patients who had undergone unilateral, bilateral or recurrent repair of inguinal hernias using either endoscopic or open techniques between September 1, 2009, and March 5, 2014. In total, 85,033 patients were enrolled. Of these patients, 48,201 (56.7 %) had an endoscopic and 36,832 (43.3 %) an open repair. The target variables analyzed were impaired wound healing and deep infections with mesh involvement within 30 days after the operation. Results Analysis of the patient group with endoscopic/laparoscopic inguinal hernia repair (n = 48,201) did not identify any significant influence of antibiotic prophylaxis on postoperative impaired wound healing, which occurred in 53 cases (p = 0.6431). Nor was it possible to identify any significant impact of antibiotic prophylaxis on the deep infections seen in 27 cases (p = 0.8409). Analysis of the open inguinal hernia repair group revealed that, unlike the laparoscopic/endoscopic group, antibiotic prophylaxis had a significant impact on the postoperative impaired wound healing and deep infection rates. The risk of postoperative impaired wound healing with antibiotic prophylaxis was significantly lower [OR 0.677 (0.479; 0.958), p = 0.027]. Conclusion The positive impact of the endoscopic/laparoscopic technique on avoidance of impaired wound healing and deep infections with mesh involvement is already so great that antibiotic prophylaxis has no additional benefit. In contrast, antibiotic prophylaxis should be administered for open inguinal hernia repair.

Abstract
OBJECTIVE Inguinal hernia operations are common procedures in general surgery. There have been many approaches in the historical development of hernia repair; tension free repair with mesh being the most commonly used technique today. Although it is a clean wound, antibiotic use is still controversial due to concerns about infection related to synthetic mesh. We aimed to determine the probable role of topical rifampicin in patients with tension-free hernia repair and mesh support. MATERIAL AND METHODS The charts of patients who underwent tension-free inguinal hernia repair were retrospectively analyzed. Information and operative notes on patients, in whom synthetic materials were used, were identified. The patients were divided into two groups, placebo group (G1) and patients with application of topical rifampicin on the mesh (G2). Infection rates between the groups in the early postoperative period were compared. RESULTS The mean age of the 278 patients who were included in the study was 49.6±15.39 and the female/male ratio was 10/268. There were recurrent hernias in four patients and superficial wound infections in 22 patients in the early period. One patient had testicle torsion and underwent an orchiectomy. There were no significant differences between the groups in terms of age and gender. The types of hernia and body mass index were homogenous between the two groups. In the early postoperative period the infection rates were 16/144 (11.1%) and 6/134 (4.48%) in the groups, respectively, with the difference being statistically significant (p=0.041). CONCLUSION We suggest that applying rifampicin locally can decrease surgical site infection in hernia operations where meshes are used.

Abstract
Purpose Evidence regarding whether or not antibiotic prophylaxis is beneficial in preventing post-operative surgical site infection in adult inguinal hernia repair is conflicting. A recent Cochrane review based on 17 randomised trials did not reach a conclusion on this subject. This study aimed to describe the current practice and determine whether clinical equipoise is prevalent. Methods Surgeons in training were recruited to administer the Survey of Hernia Antibiotic Prophylaxis usE survey to consultant-level general surgeons in London and the south-east of England on their practices and beliefs regarding antibiotic prophylaxis in adult elective inguinal hernia repair. Local prophylaxis guidelines for the participating hospital sites were also determined. Results The study was conducted at 34 different sites and received completed surveys from 229 out of a possible 245 surgeons, a 93 % response rate. Overall, a large majority of hospital guidelines (22/28) and surgeons’ personal beliefs (192/229, 84 %) supported the use of single-dose pre-operative intravenous antibiotic prophylaxis in inguinal hernia repair, although there was considerable variation in the regimens in use. The most widely used regimen was intravenous co-amoxiclav (1.2 g). Less than half of surgeons were adherent to their own hospital antibiotic guidelines for this procedure, although many incorrectly believed that they were following these. Conclusion In the south-east of England, there is a strong majority of surgical opinion in favour of the use of antibiotic prophylaxis in this procedure. It is therefore likely to be extremely difficult to conduct further randomised studies in the UK to support or refute the effectiveness of prophylaxis in this commonly performed procedure.

Abstract
BACKGROUND There is no clear answer regarding the use of laparoscopic techniques versus the Lichtenstein method for the treatment of recurrent inguinal hernia. OBJECTIVE The aim of this study was to compare the outcomes of laparoscopy versus the Lichtenstein repair by a meta-analysis of available randomized controlled trials (RCTs). METHODS Databases, including PubMed, EMBASE, the Cochrane Library, and the Science Citation Index updated to May 2012, were searched. The main outcome measures were wound infections and haematoma, urinary retention, post-operative chronic pain and recurrence. A meta-analysis of included RCTs was performed. RESULTS Five RCTs, comprising a total of 427 patients, were included. Although most of the analysed outcomes were similar between groups, wound infection rates and post-operative chronic pain occurred less frequently in the laparoscopic group than in the Lichtenstein group (odds ratio: 0.28, 95% CI: 0.08-0.97; P = 0.05; odds ratio: 0.33, 95% CI: 0.17-0.68; P = 0.002, respectively). CONCLUSION The laparoscopic approach to the treatment of recurrent inguinal hernia is superior to the Lichtenstein hernioplasty in some aspects that affect patient satisfaction.
