Sæter AH, Fonnes S, Rosenberg J, Andresen K. Mortality after emergency versus elective groin hernia repair: a systematic review and meta-analysis. Surg Endosc 2022; 36:7961-7973. [PMID: 35641700 DOI: 10.1007/s00464-022-09327-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 04/30/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Emergency groin hernia repair is associated with increased mortality risk, but the actual risk is unknown. Therefore, this review aimed to investigate 30- and 90-day postoperative mortality in adult patients who had undergone emergency or elective groin hernia repair. METHODS This review was reported following PRISMA 2020 guidelines, and a protocol (CRD42021244412) was registered to PROSPERO. A systematic search was conducted in PubMed, EMBASE, and Cochrane CENTRAL in April 2021. Studies were included if they reported 30- or 90-day mortality following an emergency or elective groin hernia repair. Meta-analyses were conducted when possible, and subgroup analyses were made for bowel resection, sex, and hernia type. According to the study design, the risk of bias was assessed using either the Newcastle-Ottawa Scale or Cochrane Risk of Bias tool. RESULTS Thirty-seven studies with 30,740 patients receiving emergency repair and 457,253 receiving elective repair were included. The 30-day mortality ranged from 0-11.8% to 0-1.7% following emergency and elective repair, respectively. The risk of 30-day mortality following emergency repair was estimated to be 26-fold higher than after elective repair (RR = 26.0, 95% CI 21.6-31.4, I2 = 0%). A subgroup meta-analysis on bowel resection in emergency repair estimated 30-day mortality to be 7.9% (95% CI 6.5-9.3%, I2 = 6.4%). Subgroup analyses on sex and hernia type showed no differences regarding the mortality risk in elective surgery. However, femoral hernia and female sex significantly increased the risk of mortality in emergency surgery, both given by a risk ratio of 1.7. CONCLUSION The overall mortality after emergency groin hernia repair is 26-fold higher than after elective repair, but the increased risk is attributable mostly to female and femoral hernias. TRIAL REGISTRATION PROSPERO protocol (CRD42021244412).

Abstract
Background: Prevention of surgical site infection (SSI) in hernia repair with mesh remains the main concern. Many risk factors have been proposed; however, the role of changing the glove remains to be elucidated. Methods: This longitudinal study was conducted on adult inguinal hernia cases referred to elective repair using mesh reconstruction. Two hundred cases were enrolled and classified into two groups, including the group that surgeon and his assistants changed the glove and the group in which the gloves remained unchanged. Age, gender, surgery duration, and the side of hernia were compared between those who developed SSI and those without this complication. Moreover, the infection rate was compared between the two study groups. Results: One hundred and two males (51.0%) and 98 females (49.0%) with a mean age of 42.60 ± 15.79 years old were enrolled in the study. None of the variables showed a significant difference between SSI cases and non-SSI cases. Moreover, the rate of infection was not significantly different between the two study groups. Conclusions: Glove changing before mesh application indicates no considerable role in reducing SSI rate; however, further studies are needed to confirm these findings.

Abstract
OBJECTIVE To study the possibility of totally extraperitoneal repair combined with diagnostic laparoscopy in the treatment of strangulated groin hernias (Laparoscopy-Assisted Totally Extraperitoneal Plasty, LATEP). MATERIAL AND METHODS We analyzed the results of laparoscopic totally extraperitoneal hernia repair. The trocar placement technique was modified. There were 38 patients with strangulated groin hernia. The sample included 26 patients with strangulated inguinal hernia, 9 ones with strangulated femoral hernia and 3 patients with recurrent strangulated inguinal hernia. RESULTS LATEP was attempted in 38 patients and successful in 37 (97.3%) cases. In 1 (2.6%) patient, correction of small bowel strangulation was failed and conversion to open surgery was required. In 29 patients (76.3%), correction of strangulation was performed after laparoscopy-assisted external manipulations and careful traction from abdominal cavity. In 8 (21%) cases, strangulation spontaneously regressed before laparoscopy. Laparoscopy confirmed viability of strangulated organs in 36 patients. One (2.6%) patient required bowel resection due to small intestine wall necrosis. Later, all patients underwent totally extraperitoneal repair. We were able to prevent the contact of hernia sac fluid with the implant in all cases. At the stage of preperitoneal repair, local damage to peritoneum occurred in 9 patients. Nevertheless, sealing was not required since hernia fluid was previously removed from abdominal cavity. There were no signs of implant infection and hernia recurrence within 6-14 months. CONCLUSION Totally extraperitoneal repair combined with diagnostic laparoscopy is possible for strangulated groin hernias.

Surgery 2022; 172:193-197. [PMID: 35304009 DOI: 10.1016/j.surg.2022.01.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 12/29/2021] [Accepted: 01/15/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND The utility of preoperative computed tomography for urgent abdominal wall hernia repair is unclear. This study tests the hypothesis that there is no difference in patient outcomes for acutely incarcerated ventral or inguinal hernias diagnosed by preoperative computed tomography versus clinical assessment alone. METHODS This retrospective cohort analysis included 270 adult patients undergoing urgent repair of ventral or inguinal hernia. Demographics, risk factors for complications, operative management strategies, and 1-year outcomes were compared between patients with (n = 179) versus without (n = 91) preoperative computed tomography. RESULTS Among 179 preoperative computed tomography scans, 15 (8.4%) were ordered by surgeons, and all others were ordered by referring providers. The computed tomography and no computed tomography groups had similar age (58 vs 58 years, P = .77), body mass index (30.7 vs 30.6 kg/m2, P = .30), American Society of Anesthesiologists class (3.0 vs 3.0, P = .39), incidence of the systemic inflammatory response syndrome (19.0% vs 20.9%, P = .75), and incidence of recurrent hernia (16.8% vs 19.8%, P = .61). The interval between admission and incision was longer in the computed tomography group (11.2 hours vs 6.6 hours, P < .001). The computed tomography and no computed tomography groups had similar duration of surgery (125 minutes in both groups, P = .88), proportions of patients with biologic mesh (21.2% vs 17.6%, P = .52) and synthetic mesh (35.2% vs 46.2%, P = .09) placement, and 1-year outcomes including incidence of superficial (8.4% vs 6.6%, P = .81) and deep or organ/space surgical site infection (5.0% vs 6.6%, P = .59), mesh explant for infection (2.2% vs 3.3%, P = .69), reoperation for recurrent hernia (3.9% vs 1.1%, P = .27), and mortality (7.8% vs 4.4%, P = .44). CONCLUSION The performance of preoperative computed tomography was associated with a longer interval between admission and incision and no differences in mesh placement, mesh type, or 1-year patient outcomes. These results support the safety of performing urgent repair of acutely incarcerated ventral or inguinal hernias based on clinical assessment alone.

Synthetic Mesh in Contaminated Abdominal Wall Surgery: Friend or Foe? A Literature Review. J Gastrointest Surg 2022; 26:235-244. [PMID: 34590215 DOI: 10.1007/s11605-021-05155-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 09/17/2021] [Indexed: 01/31/2023]
Abstract
INTRODUCTION The use of synthetic mesh in contaminated fields is controversial. In the last decade, published data have grown in this matter suggesting favorable outcomes. However, multiple variables and scenarios that influence the results still make difficult to obtain convincing recommendations. METHODS We performed a review of relevant available data in English regarding the use of synthetic meshes in contaminated abdominal wall surgery using the Medline database. Articles including patients undergoing ventral hernia in contaminated fields were included for analysis. RESULTS Most studies support the use of synthetic meshes for ventral hernia repair in contaminated fields, as they have shown lower recurrence rate and similar wound morbidity. Although no mesh seems ideal in this setting, most surgeons advocate for the use of reduced-in-weight polypropylene mesh. Sublay location of the prosthesis associated with complete fascial closure appears to offer better results in these patients. In addition, current evidence suggests that the use of prophylactic synthetic mesh when performing a stoma or for stoma reversal incisional hernias might be beneficial. CONCLUSION A better understanding of surgical site occurrences and its prevention, as well as the introduction of new reduced-in-weight meshes have allowed using synthetic meshes in a contaminated field. Although the use of mesh has indeed shown promising results in these patients, the surgical team should still balance pros and cons at the time of placing synthetics in contaminated fields.

Abstract
Background: The mesh infection is mostly related to the gram-negative bacteria, such as Escherichia coli (E. coli) for emergency surgery of incarcerated hernia. However, few study investigated the effects of E. coli concentration, mesh materials and antibiotic prophylaxis on mesh infection after hernioplasty. The aim of this study was to evaluate the bacterial resistance to E. coli for three different materials of mesh, and to measure the minimum E. coli concentration for mesh infection with and without antibiotic prophylaxis in a rat model. Methods: Three types of mesh (polytetrafluoroethylene, polypropylene, and biologic meshes) were used in the repair of an acute ventral hernia rat model in the setting of different concentrations of E. coli loads and antibiotics. At the 8th day after surgery, mesh samples were sent for microbiologic and histologic analyses. Results: The positive rates of bacterial culture increased with E. coli concentration. The biologic mesh showed better bacterial resistance compared to polytetrafluoroethylene mesh and polypropylene mesh when the concentration of E. coli ranges from 106 CFU/ml to 108 CFU/ml (P = 0.002 and P = 0.029, respectively). Prophylactical ceftriaxone treatment could not decrease the colonization rate of E. coli at 106 CFU/ml or 108 CFU/ml in each group (P > 0.05). The scores of neovascularization in polypropylene mesh and biologic mesh were similar, which was higher than that of polytetrafluoroethylene mesh (P < 0.05). Compared with other meshes, biologic mesh showed better tolerance to 106 CFU/ml E. coli with respect to inflammation, depth of inflammation, neovascularization, cellular repopulation and foreign body giant cells. Conclusion: The biologic mesh had better E. coli resistance compared to polytetrafluoroethylene mesh and polypropylene mesh when the E. coli concentration is higher than 106 CFU/ml in rats. Antibiotic prophylaxis was useful when the contamination was not particularly severe.

Abstract
INTRODUCTION Inguinal hernia mesh infection (IHMI) is a rare but a significant problem. The aim of this study was to determine whether etiopathogeneses of early-onset and late-onset IHMIs differ in terms of the origin of infectious agents, and route of dissemination. PATIENTS AND METHODS This was a retrospective cohort study with prospective data collection of patients operated on from 2013 to 2015. Early-onset IHMI was defined as symptoms developed within one year after the index surgery, whereas late-onset IHMI was defined as infection developed later than a year after the index surgery. Age, gender, ASA score, BMI, time from index surgery, isolated infectious agents and possible pathogeneses were analyzed. RESULTS During the study period, 1438 patients underwent inguinal hernia repair. Sixteen patients (1.1%) had IHMI, of whom nine were early-onset and seven late-onset. The groups were comparable for age (p = .54), gender (p = 1.0), BMI (p = .79), and ASA score (p = 1.0). The most common infectious agent in early-onset IHMI was St. aureus, whereas Enterococci and Enterobacter prevailed in late-onset IHMI. The possible pathogenesis of IHMI in seven patients with early-onset IHMI was primary exogenous infection, whereas in patients with late-onset IHMI the pathogenesis might be hematogenous or contact spread. All patients with IHMI underwent mesh removal. In two patients (one from each group), partial mesh removal was performed previously and IHMI recurred. CONCLUSIONS Early-onset hernia mesh infection is mostly caused by St. aureus through exogenous contamination, whereas its late-onset counterpart might be a result of hematogenous or contact spread of intestinal flora.

Abstract
Worldwide, hernia repair represents one of the most frequent surgical procedures encompassing a global market valued at several billion dollars. This type of surgery usually requires the implantation of a mesh that needs the appropriate chemical, physical and biological properties for the type of repair. This review thus presents a description of the types of hernias, current hernia repair methods, and the state of the art of prosthetic meshes for hernia repair providing the most important meshes used in clinical practice by surgeons working in this area classified according to their biological or chemical nature, morphology and whether bioabsorbable or not. We emphasise the importance of surgical site infection in herniatology, how to deal with this microbial problem, and we go further into the future research lines on the production of advanced antimicrobial meshes to improve hernia repair and prevent microbial infections, including multidrug-resistant strains. A great deal of progress has been made in this biomedical field in the last decade. However, we are still far from an ideal antimicrobial mesh that can also provide excellent integration to the abdominal wall, mechanical performance, low visceral adhesion and minimal inflammatory or foreign body reactions, among many other problems.

Abstract
Plasma-based treatment is a prevalent strategy to alter biological response and enhance biomaterial coating quality at the surfaces of biomedical devices and implants, especially polymeric materials. Plasma, an ionized gas, is often thought to have negligible effects on the bulk properties of prosthetic substrates given that it alters the surface chemistry on only the outermost few nanometers of material. However, no studies to date have systematically explored the effects of plasma exposure on both the surface and bulk properties of a biomaterial. This work examines the time-dependent effects of a nonthermal plasma on the surface and bulk (i.e. mechanical) properties of polymeric implants, specifically polypropylene surgical meshes and sutures. Findings suggest that plasma exposure improved resistance to fibrinogen adsorption and Escherichia coli attachment, and promoted mammalian fibroblast attachment, although increased duration of exposure resulted in a state of diminishing returns. At the same time, it was observed that plasma exposure can be detrimental to the material properties of individual filaments (i.e. sutures), as well as the structural characteristics of knitted meshes, with longer exposures resulting in further embrittlement and larger changes in anisotropic behavior. Though there are few guidelines regarding appropriate mechanical properties of surgical textiles, the results from this investigation imply that there are ultimate exposure limits for plasma-based treatments of polymeric implant materials when structural properties must be preserved, and that the effects of a plasma on a given biomaterial should be examined carefully before translation to a clinical scenario.

Abstract
PURPOSE Morbidity and mortality are higher in urgently operated abdominal hernia cases compared to elective surgeries. The present study aims to investigate the factors that cause increased morbidity and mortality in emergency surgical operations. METHODS The files of a total of 426 patients who were operated for non-reducible abdominal hernia between 2015 and 2020 were reviewed retrospectively. Patients' ages, genders, comorbidities, Charlson Comorbidity Index (CCI), ASA score, BMI, hernia types, duration of symptom, laboratory values, intestinal strangulations or necroses, whether intestinal resection was performed, whether mesh was preferred for hernia repair, and rates of morbidity and mortality were recorded. Factors affecting morbidity and mortality rates were analyzed. RESULTS Factors such as gender, BMI (> 30), duration of symptom (> 24 h), presence of bowel necrosis and resection, type of hernia and prolonged operation time were found to cause an increase in morbidity. In the multivariate analysis, however, gender, duration of symptom and BMI (> 30) were statistically significant factors causing increased morbidity (p = 0.009, p < 0.001, p = 0.032, respectively). Advanced age, high ASA scores, CCI and duration of symptom were determined as factors affecting the increase in mortality. In the multivariate analysis, the effect of high ASA scores and advanced age on high mortality rate was statistically significant (p < 0.023, p = 0.039, respectively). CONCLUSIONS The mortality rate is higher, especially in elderly patients with high comorbidity. Therefore, we argue that the cases of abdominal wall hernia should be operated under elective conditions even if they do not give any clinical findings to prevent problems in older ages.

Abstract
To compare the outcomes of open preperitoneal repair (OPR) with the use of mesh and open suture repair (OSR) without mesh via inguinal approach for the treatment of emergency femoral hernia (FH). The primary outcome was the postoperative complication and the secondary outcomes were the recurrence rate of FH and the postoperative comfort level at the surgical site. 104 patients with emergency FHs were included, of whom 51 patients were treated with OPR, 53 patients were treated with OSR. Between the two groups, no significant difference was found in surgical site infection (SSI) (P = 0.801) or seroma (P = 0.843), while there was significant difference in the improvement of comfort at the surgical site (P = 0.013). The results of the 2-year follow-up demonstrated 1 and 8 cases of recurrence in the OPR and OSR group respectively, which was statistically significant (HR, 8.193 [95% CI, 1.024 to 65.547], P = 0.047). Compared with OSR, OPR with the use of mesh did not increase the risk of SSI and was safe to apply even under the condition of an emergency FH operation with intestine resection; OPR could reduce the recurrence rate of FH and improve the comfort at the surgical site.

Abstract
Management of incarcerated hernias is a common issue facing general surgeons across the USA. When hernias are not able to be reduced, surgeons must make decisions in a short time frame with limited options for patient optimization. In this article, we review assessment and management options for incarcerated ventral and inguinal hernias.

Abstract
Currently, hernia treatment involves implantation of a mesh prosthesis, usually made of polypropylene, and the primary complication is infection of the device, which leads to an exponential increase in morbidity. Three-dimensional printing offers a method of dealing with complications of this magnitude. Therefore, in this study, the bactericidal properties and effectiveness of three-dimensional-printed meshes with polycaprolactone (PCL) and gentamicin were evaluated in vitro in Escherichia coli cultures, and their histological behaviour was examined in vivo. Different PCL meshes were implanted into four groups of rats, with 10 rats in each group: PCL meshes, PCL meshes with alginate and calcium chloride, PCL meshes with gentamicin, and PCL meshes with alginate and gentamicin. Thirty-six microporous meshes were manufactured, and their bactericidal properties were assessed. When the meshes did not include an antibiotic, an inhibition halo was not observed; when the gentamicin was free, an asymmetric inhibition area of 5.65 ± 0.46 cm2 was present; when the gentamicin was encapsulated, a rectangular area of 5.40 ± 0.38 cm2 was observed. In the rats, macroporous and microporous mesh implants produced mild inflammation and substantial fibrosis with collagen and neovascular foci. A significant difference was observed in fibroblastic activity between the PCL with alginate group and the PCL with alginate and gentamicin group microporous meshes (p = .013) and in collagen deposits between the macroporous and microporous meshes in the PCL mesh group (p = .033). The feasibility of manufacturing drug-doped printed PCL meshes containing alginate and gentamicin was verified, and the meshes exhibited bactericidal effects and good histopathological behaviour.

Abstract
The evaluation of biological responses to polymeric scaffolds are important, given that the ideal scaffold should be biocompatible, biodegradable, promote cell adhesion and aid cell proliferation. The primary goal of this research was to measure the biological responses of cells against various polymeric and collagen electrospun scaffolds (polycaprolactone (PCL) and polylactic acid (PLA) polymers: PCL⁻drug, PCL⁻collagen⁻drug, PLA⁻drug and PLA⁻collagen⁻drug); cell proliferation was measured with a cell adhesion assay and cell viability using 5-bromo-2'-deoxyuridine (BrdU) and resazurin assays. The results demonstrated that there is a distinct lack of growth of cells against any irgasan (IRG) loaded scaffolds and far greater adhesion of cells against levofloxacin (LEVO) loaded scaffolds. Fourteen-day studies revealed a significant increase in cell growth after a 7-day period. The addition of collagen in the formulations did not promote greater cell adhesion. Cell viability studies revealed the levels of IRG used in scaffolds were toxic to cells, with the concentration used 475 times higher than the EC50 value for IRG. It was concluded that the negatively charged carboxylic acid group found in LEVO is attracting positively charged fibronectin, which in turn is attracting the cell to adhere to the adsorbed proteins on the surface of the scaffold. Overall, the biological studies examined in this paper are valuable as preliminary data for potential further studies into more complex aspects of cell behaviour with polymeric scaffolds.

Hernia 2018; 23:267-276. [PMID: 30421299 PMCID: PMC6456471 DOI: 10.1007/s10029-018-1854-5] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Accepted: 11/08/2018] [Indexed: 11/12/2022]
Abstract
Purpose This study aimed to explore risk factors of postoperative complications for adult patients with incarcerated groin hernia (IGH). Methods From January 2010 to December 2017, consecutive patients undergoing emergency hernia repair for IGH in our center were retrospectively reviewed. Postoperative complications, such as surgical site infection, seroma, hernia recurrence and mortality, were investigated, with risk factors for such complications analyzed using univariate and multivariate regressions. Results Sixty-four patients were included, with 51 males and 13 females (mean age 65.1, range 25–98 years). Ten patients (15.6%) underwent resection of necrotic bowel and anastomosis. 43 patients (67.2%) received open tension-free herniorrhaphy with polypropylene mesh, whereas the rest (32.8%) received herniorrhaphy without mesh. The overall postoperative complication rate was 40.6% (26/64), with an incisional complication rate of 31.2% (20/64) and an infection rate of 6.2% (4/64). At a median follow-up of 32 months, hernia recurrence and mortality were recorded in five cases each (7.8%). Mesh repair was associated with decreased recurrence rate compared with non-mesh repair (2.3% vs. 19.0%, p = 0.019). Diabetes mellitus (OR 8.611, 95%CI 1.292–57.405; p = 0.026) was an independent risk factor of postoperative complications, together with chronic obstructive pulmonary disease (COPD; OR 14.365, 95%CI 1.652–127.767, p = 0.016), intestinal necrosis (OR 14.260, 95%CI 1.079–188.460, p = 0.044), and general anesthesia (OR 14.543, 95%CI 1.682–125.711, p = 0.015) as risk for incisional complications after surgery. Conclusions Diabetes mellitus was an independent risk factor of postoperative complications for IGH, along with COPD, intestinal necrosis and general anesthesia associated with incisional complications. The use of polypropylene mesh did not increase infection or recurrence rate in this cohort.

Abstract
Inguinal hernia mesh repair is one of the most frequent operations performed worldwide. The Lichtenstein technique and its various modifications are the most popular operations for groin hernia repair. The rate of surgical site infection (SSI) following inguinal hernia repair ranges between 0 and 14% in various series. Most of these infections developed early postoperatively. The incidence of late mesh infection following open inguinal hernia repair still remains unclear and highly variable. Late deep mesh infections are relatively rare specially after more than 10 years. The most common pathogens reported in the literature are E. coli and St. aureus. The infection is treated by conservative means initially but in case of failure then the mesh should be removed surgically. A unique case of a patient with very late (chronic) mesh infection is presented. The infection was due to Pseudomonas aeruginosa, which occurred 14 years after the initial operation and presented as subcutaneous fistula.

Abstract
BACKGROUND Mesh placement during repair of acutely incarcerated ventral and groin hernias is associated with high rates of surgical site infection (SSI). The utility of preoperative computed tomography (CT) in this setting is unclear. We hypothesized that CT evidence of bowel wall compromise would predict SSI while accounting for physiologic parameters. METHODS We performed a 4-year retrospective cohort analysis of 50 consecutive patients who underwent mesh repair of acutely incarcerated ventral or groin hernias. We analyzed chronic disease burden, acute illness severity, CT findings, operative management, and herniorrhaphy-specific outcomes within 180 days. The primary outcome was SSI by the Centers for Disease Control and Prevention criteria. Multiple logistic regression was performed to identify independent predictors of SSI. RESULTS Eighty-four percent of all patients were American Society of Anesthesiologists class III or IV, 28% were active smokers, and mean body mass index (BMI) was 35 kg/m. Fifty-four percent had ventral hernias, 40% had inguinal hernias, and 6% had femoral or combined inguinal/ femoral hernias. Seventy percent of preoperative CT scans had features suggesting bowel compromise, abdominal free fluid, or fluid in the hernia sac. Surgical site infection occurred in 32% of all patients (8% superficial, 24% deep or organ/space). The strongest predictors of SSI were CT evidence of fluid in the hernia sac (odds ratio [OR], 8.3; 95% confidence interval [CI], 1.7-41), initial heart rate 90 beats/min or greater (OR, 6.3; 95% CI, 1.1-34), and BMI 35 kg/m or greater (OR, 5.8; 95% CI, 1.2-28). Surgical site infection rates were significantly higher among patients who had CT evidence of fluid in the hernia sac (56% vs. 19%, p = 0.012). CONCLUSIONS More than half of all patients with CT scan evidence of fluid in the hernia sac developed an SSI. Computed tomography evidence of fluid in the hernia sac was the strongest predictor of SSI, followed by heart rate and BMI. Together, these parameters identify high-risk patients for whom better strategies are needed to avoid SSI without sacrificing durability. LEVEL OF EVIDENCE Prognostic study, level III; Therapeutic, level IV.

A fascia lata free flap in pelvic exenteration for Fournier gangrene due to advanced rectal cancer: a case report. Surg Case Rep 2017; 3:74.

Abstract
Background Fournier gangrene due to advanced rectal cancer is a rapidly progressive gangrene of the perineum and buttocks. Emergency surgical debridement of necrotic tissue is crucial, and secondary surgery to resect tumors is necessary for wound healing. However, pelvic exenteration damages the pelvic floor, increasing the likelihood of herniation of internal organs into the infectious wound. The management of pelvic exenteration for rectal cancer with Fournier gangrene has not yet been established. We herein describe the use of a fascia lata free flap in pelvic exenteration for rectal cancer with Fournier gangrene. Case presentation A 66-year-old male who had undergone colostomy for large bowel obstruction due to advanced rectal cancer and continued chemotherapy was referred to our hospital for Fournier gangrene resulting from chemotherapy. Emergency surgical debridement was performed, and the infectious wound around the rectal cancer was treated with intravenous antibiotic agents postoperatively. However, the tumor was exposed by the wound, and exudate persisted. Pelvic exenteration was performed due to tumor infiltration into the bladder and prostate. Tumor resection resulted in a defect in the pelvic floor. A fascia lata free flap (15 × 9 cm) obtained from the left thigh was fixed to the edge of the peritoneum and ileal conduit to close the defect in the pelvic floor and prevent small bowel herniation into the resected space. There was no intraabdominal inflammation or bowel obstruction postoperatively, and outpatient chemotherapy was continued. Conclusions Surgical repair with a fascia lata free flap to close the defect in the pelvic floor led to a good clinical outcome for pelvic exenteration in a patient with Fournier gangrene due to advanced rectal cancer.

Abstract
Superficial surgical site infections (S-SSIs), which prolonged hospital stay and increased costs, are a critical problem. The aim of the present study was to clarify the risk factors for S-SSIs after urgent gastroenterologic surgery and what surgeons can do to reduce their incidence and to shorten the hospital stay. A total of 275 patients who underwent urgent gastroenterologic surgery were enrolled in the present study. The correlations between the incidence of S-SSIs and clinicopathologic factors were retrospectively analyzed using propensity score matching. Of 275 cases, 43 (15.6%) patients had an S-SSI. On univariate analysis, the following factors were associated with a significantly higher incidence of S-SSI: American Society of Anesthesiologists score (P = 0.043); wound classification (P = 0.0005); peritonitis (P = 0.019); prolonged operation time (P = 0.0001); increased blood loss (P = 0.019); transfusion (P = 0.0047); and abdominal closure without triclosan-coated polydioxanone sutures (P = 0.042). However, a propensity score–matching analysis showed that abdominal closure using triclosan-coated polydioxanone sutures did not reduce the incidence of S-SSIs in patients who underwent urgent gastroenterologic surgery (P = 0.20), but it tended to be associated with a shorter hospital stay (P = 0.082). To reduce morbidity after urgent gastroenterologic surgery, surgeons should shorten the operation time and decrease the blood loss. In addition, abdominal closure using triclosan-coated polydioxanone sutures alone could not reduce the incidence of S-SSIs but might shorten the hospital stay after urgent gastroenterologic surgery by inhibiting bacterial activity and preventing prolongation of the infections.

Abstract
We present two cases of incarcerated de Garengeot's hernia. This anatomical phenomenon is thought to occur in as few as 0.5% of femoral hernia cases and is a rare cause of acute appendicitis. Risk factors include a long pelvic appendix, abnormal embryological bowel rotation, and a large mobile caecum. In earlier reports operative treatment invariably involves simultaneous appendicectomy and femoral hernia repair. Both patients were correctly diagnosed preoperatively with computed tomography (CT). Both had open femoral hernia repair, one with appendectomy and one with the appendix left in situ. Both patients recovered without complications. Routine diagnostic imaging modalities such as ultrasonography and standard CT have previously shown little success in identifying de Garengeot's hernia preoperatively. We believe this to be the first documented case of CT with concurrent oral and intravenous contrast being used to confidently and correctly diagnose de Garengeot's hernia prior to surgery. We hope that this case report adds to the growing literature on this condition, which will ultimately allow for more detailed case-control studies and systematic reviews in order to establish gold-standard diagnostic studies and optimal surgical management in future.

Abstract
Background Despite meticulous aseptic technique and systemic antibiotics, bacterial colonization of mesh remains a critical issue in hernia repair. A novel minocycline/rifampin tyrosine-coated, noncrosslinked porcine acellular dermal matrix (XenMatrix AB) was developed to protect the device from microbial colonization for up to 7 days. The objective of this study was to evaluate the in vitro and in vivo antimicrobial efficacy of this device against clinically isolated methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli. Methods XenMatrix AB was compared with 5 existing uncoated soft tissue repair devices using in vitro methods of zone of inhibition (ZOI) and scanning electron microscopy (SEM) at 24 hours following inoculation with MRSA or E coli These devices were also evaluated at 7 days following dorsal implantation and inoculation with MRSA or E coli (60 male New Zealand white rabbits, n = 10 per group) for viable colony-forming units (CFU), abscess formation and histopathologic response, respectively. Results In vitro studies demonstrated a median ZOI of 36 mm for MRSA and 16 mm for E coli for XenMatrix AB, while all uncoated devices showed no inhibition of bacterial growth (0 mm). SEM also demonstrated no visual evidence of MRSA or E coli colonization on the surface of XenMatrix AB compared with colonization of all other uncoated devices. In vivo XenMatrix AB demonstrated complete inhibition of bacterial colonization, no abscess formation, and a reduced inflammatory response compared with uncoated devices. Conclusion We demonstrated that XenMatrix AB possesses potent in vitro and in vivo antimicrobial efficacy against clinically isolated MRSA and E coli compared with uncoated devices.

Abstract
BACKGROUND Local anesthesia (LA) has been reported to be the best choice for elective open inguinal hernia repair because it is cost efficient, with less post-operative pain and enables more rapid recovery. However, the role of LA in emergency inguinal hernia repair is still controversial. The aim of this study is to investigate the safety and effectiveness of LA in emergency inguinal hernia repair. METHODS All patients underwent emergency inguinal hernia repair in our hospital between January 2010 and April 2014 were analyzed retrospectively in this study. Patients were divided into LA and general anesthesia (GA) group according to the general conditions of the patients decided by anesthetists and surgeons. The outcome parameters measured included time to recovery, early and late postoperative complications, total expense and recurrence. RESULTS This study included a total of 90 patients from 2010 to 2015. 32 patients (35.6%) were performed under LA, and 58 (64.4%) were performed under GA. LA group has less cardiac complications (P = 0.044) and respiratory complications (P = 0.027), shorter ICU stay (P = 0.035) and hospital stay (P = 0.001), lower cost (P = 0.000) and faster recovery time (P = 0.000) than GA group. CONCLUSION LA could provide effective anesthesia and patient safety in emergency inguinal hernia repair.
