Global, regional, and national burden of inguinal, femoral, and abdominal hernias: a systematic analysis of prevalence, incidence, deaths, and DALYs with projections to 2030.

BACKGROUND: Hernias, particularly inguinal, femoral, and abdominal, present a global health challenge. While the global burden of disease (GBD) study offers insights, systematic analyses of hernias remain limited. This research utilizes the GBD dataset to explore hernia implications, combining current statistics with 2030 projections and frontier analysis. METHODS: We analyzed data from the 2019 GBD Study, focusing on hernia-related metrics: prevalence, incidence, deaths, and disability-adjusted life years (DALYs) across 204 countries and territories, grouped into 21 GBD regions by the socio-demographic index (SDI). Data analysis encompassed relative change calculations, as well as annual percentage change (APC) and average annual percentage change (AAPC), both of which are based on joinpoint regression analysis. The study additionally employed frontier analysis and utilized the Bayesian age-period-cohort model for predicting trends up to 2030. Analyses utilized R version 4.2.3. RESULTS: From 1990 to 2019, the global prevalence of hernia cases surged by 36%, reaching over 32.5 million, even as age-standardized rates declined. A similar pattern was seen in mortality and DALYs, with absolute figures rising but age-standardized rates decreasing. Gender data between 1990 and 2019 showed consistent male dominance in hernia prevalence, even as rates for both genders fell. Regionally, Andean Latin America had the highest prevalence, with Central Sub-Saharan Africa and South Asia noting significant increases and decreases, respectively. Frontier analyses across 204 countries and territories linked higher SDIs with reduced hernia prevalence. Yet, some high SDI countries, like Japan and Lithuania, deviated unexpectedly. Predictions up to 2030 anticipate increasing hernia prevalence, predominantly in males, while age-standardized death rates and age-standardized DALY rates are expected to decline. CONCLUSIONS: Our analysis reveals a complex interplay between socio-demographic factors and hernia trends, emphasizing the need for targeted healthcare interventions. Despite advancements, vigilance and continuous research are essential for optimal hernia management globally.

Do surgical emergencies stay at home? Observations from the first United States Coronavirus epicenter.

BACKGROUND: During the coronavirus disease 2019 pandemic, New York instituted a statewide stay-at-home mandate to lower viral transmission. While public health guidelines advised continued provision of timely care for patients, disruption of safety-net health care and public fear have been proposed to be related to indirect deaths because of delays in presentation. We hypothesized that admissions for emergency general surgery (EGS) diagnoses would decrease during the pandemic and that mortality for these patients would increase. METHODS: A multicenter observational study comparing EGS admissions from January to May 2020 to 2018 and 2019 across 11 NYC hospitals in the largest public health care system in the United States was performed. Emergency general surgery diagnoses were defined using International Classification Diseases, Tenth Revision, codes and grouped into seven common diagnosis categories: appendicitis, cholecystitis, small/large bowel, peptic ulcer disease, groin hernia, ventral hernia, and necrotizing soft tissue infection. Baseline demographics were compared including age, race/ethnicity, and payor status. Outcomes included coronavirus disease (COVID) status and mortality. RESULTS: A total of 1,376 patients were admitted for EGS diagnoses from January to May 2020, a decrease compared with both 2018 (1,789) and 2019 (1,668) (p < 0.0001). This drop was most notable after the stay-at-home mandate (March 22, 2020; week 12). From March to May 2020, 3.3%, 19.2%, and 6.0% of EGS admissions were incidentally COVID positive, respectively. Mortality increased in March to May 2020 compared with 2019 (2.2% vs. 0.7%); this difference was statistically significant between April 2020 and April 2019 (4.1% vs. 0.9%, p = 0.045). CONCLUSION: Supporting our hypothesis, the coronavirus disease 2019 pandemic and subsequent stay-at-home mandate resulted in decreased EGS admissions between March and May 2020 compared with prior years. During this time, there was also a statistically significant increase in mortality, which peaked at the height of COVID infection rates in our population. LEVEL OF EVIDENCE: Epidemiological, level IV.

Mortality and Urological Complications After Open Groin Hernia Repair in Local, General, and Regional Anesthesia: A Nationwide Linked Register Study.

BACKGROUND AND AIMS: The choice of anesthesia method may influence mortality and postoperative urological complications after open groin hernia repair. We aimed to investigate the association between type of anesthesia and incidence of urinary retention, urethral stricture, prostate surgery, and 1-year mortality after open groin hernia repair. MATERIALS AND METHODS: Data were linked from the Danish Hernia Database, the national patient register, and the register of causes of death. We investigated data on male adult patients receiving open groin hernia repair from 1999 to 2013 with either local anesthesia, regional anesthesia, or general anesthesia. In relation to the type of anesthesia, we compared mortality and urological complications up to 1 year postoperatively. We adjusted for covariates in a logistic regression assessing urological complications and with the Cox regression assessing mortality. RESULTS: We included 113,069 open groin hernia repairs in local anesthesia, regional anesthesia, or general anesthesia. The risk of urinary retention adjusted for covariates was higher after both general anesthesia (adjusted odds ratio = 1.64, 95% confidence interval = 1.05-2.57, p = 0.031) and regional anesthesia (odds ratio = 2.99, 95% confidence interval = 1.67-5.34, p < 0.0005) compared with local anesthesia. The adjusted risk of prostate surgery was also higher for both general anesthesia (odds ratio = 1.58, 95% confidence interval = 1.23-2.03, p < 0.0005) and regional anesthesia (odds ratio = 1.90, 95% confidence interval = 1.40-2.58, p < 0.0005) compared with local anesthesia. Type of anesthesia did not influence 1-year mortality or the risk for urethral stricture. CONCLUSION: Patients undergoing open groin hernia repair in local anesthesia experience the lowest rate of urological complications and have equally low mortality compared with patients undergoing repair in general anesthesia or regional anesthesia.

Continuation of antithrombotic therapy increases minor bleeding but does not increase the risk other morbidities in open inguinal hernia repair: A propensity score-matched analysis.

PURPOSE: An aging population has led to an increased number of patients with cardiovascular comorbidities requiring antithrombotic therapy. Perioperatively, surgeons should consider the increased risk of bleeding and thrombotic events in patients continuing or discontinuing these medications. We aimed to analyze the safety of continued antithrombotic therapy during open inguinal hernia repair. METHODS: In this single-center, retrospective study, 4870 adult patients who underwent open inguinal hernia repair surgery by the same surgeon from 2008 January to 2019 March were included. Patients who underwent surgery while continuing antithrombotic therapy were included in the antithrombin group (n = 523) while those who were not under any antithrombotic therapy during the surgery were included in the control group (n = 4333). Using propensity score-matching, we then selected patients from each group with similar backgrounds. Surgery time, anesthesia time, postoperative bleeding, reoperation, and thrombotic event data were compared between the groups. Subgroup analysis based on the type of medications used was performed within the antithrombin group. RESULTS: Ten patients in the antithrombin group and seven patients in the control group experienced postoperative bleeding (p < 0.001). The rate of postoperative bleeding was the highest in patients taking multiple medications. However, most were managed conservatively. Three patients from the antithrombin group experienced thrombotic events postoperatively (p = 0.001). CONCLUSIONS: Patients receiving continued antithrombotic therapy had an increased risk of minor postoperative bleeding; however, they are a high-risk group for thrombotic events.

Burden of emergency pediatric surgical procedures on surgical capacity in Uganda: a new metric for health system performance.

BACKGROUND: The significant burden of emergency operations in low- and middle-income countries can overwhelm surgical capacity leading to a backlog of elective surgical cases. The purpose of this investigation was to determine the burden of emergency procedures on pediatric surgical capacity in Uganda and to determine health metrics that capture surgical backlog and effective coverage of children's surgical disease in low- and middle-income countries. METHODS: We reviewed 2 independent and prospectively collected databases on pediatric surgical admissions at Mulago National Referral Hospital and Mbarara Regional Referral Hospital in Uganda. Pediatric surgical patients admitted at either hospital between October 2015 to June 2017 were included. Our primary outcome was the distribution of surgical acuity and associated mortality. RESULTS: A combined total of 1,930 patients were treated at the two hospitals, and 1,110 surgical procedures were performed. There were 571 emergency cases (51.6%), 108 urgent cases (9.7%), and 429 elective cases (38.6%). Overall mortality correlated with surgical acuity. Emergency intestinal diversions for colorectal congenital malformations (anorectal malformations and Hirschsprung's disease) to elective definitive repair was 3:1. Additionally, 30% of inguinal hernias were incarcerated or strangulated at time of repair. CONCLUSION: Emergency and urgent operations utilize the majority of operative resources for pediatric surgery groups in low- and middle-income countries, leading to a backlog of complex congenital procedures. We propose the ratio of emergency diversion to elective repair of colorectal congenital malformations and the ratio of emergency to elective repair of inguinal hernias as effective health metrics to track this backlog. Surgical capacity for pediatric conditions should be increased in Uganda to prevent a backlog of elective cases.

Outcomes After Inguinal Hernia Repair With Mesh Performed by Medical Doctors and Surgeons in Ghana.

Importance: Inguinal 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. Objective: To compare outcomes after inguinal hernia repair with mesh performed by medical doctors and surgeons in Ghana. Design, Setting, and Participants: This 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 Measures: The 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. Results: Two-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 Relevance: This 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.

Hernia repair in patients with chronic liver disease - A 15-year single-center experience.

BACKGROUND: Elective hernia repairs in chronic liver disease (CLD) patients are often avoided due to the fear of hepatic decompensation and mortality, leaving the patient susceptible to an emergent presentation. METHODS: CLD patients undergoing ventral or inguinal hernia repair in emergent and non-emergent settings at our institution (2001-2015) were analyzed. Predictors of 30-day morbidity and mortality (M&M) were determined using univariate analysis and multivariate logistic regression. RESULTS: A total of 186 non-emergent repairs identified acceptable rates of M&M (27%) and 90-day mortality (3.7%, 0/21 for MELD≥15). Meanwhile, 67 emergent repairs had higher rates of M&M (60%) and 90-day mortality (10%; 25% for MELD≥15). M&M was associated with elevated MELD scores in emergent cases (14 ±â€¯6 vs 11 ±â€¯4; p = 0.01) and intraoperative drain placement in non-emergent cases (OR1.31,p < 0.01). CONCLUSION: In patients with advanced CLD, non-emergent hernia repairs carry acceptable rates of M&M, while emergent repairs have increased M&M rates associated with higher MELD scores.

Emergent groin hernia repair: A single center 10-year experience.

BACKGROUND: Emergent groin hernia repair can be a challenging clinical scenario. We aimed to evaluate the perioperative and long-term outcomes of emergent groin hernia repair at our institution over the last 10 years, with particular interest in surgical approach and mesh use for such cases. METHODS: Adult patients who underwent emergent groin hernia repair from 2005-2015 were retrospectively reviewed. Outcomes included surgical site infections, perioperative complications, readmissions, reoperations, mortality, and long-term hernia recurrence. Predictors of surgical site infection and perioperative complications were investigated using multivariate logistic regression. RESULTS: A total of 257 patients met inclusion criteria (62% males, median age 72). Hernias were most often indirect inguinal (40.9%) and femoral (33.5%), and 45 cases (17.5%) required a bowel resection. Laparoscopic repair was performed in 3 patients (1.2%). Synthetic mesh was placed in 70% of repairs but in only 15% of cases associated with a bowel resection. The medical complications rate was 16.7%; 3.6% had an surgical site infection, and 30-day mortality rate was 3.1%. Older age (odds ratio 1.05) and gross contamination (odds ratio 4.3) were independently associated with complications. Mesh use was not associated with surgical site infection (odds ratio 1.83, P = .49) or perioperative complications (odds ratio 1.02, P = .96). With a median follow-up of 43 months, there were no mesh infections and recurrence rates were similar between mesh and tissue repairs (6.3% vs 6.8%, P = .91). CONCLUSION: Emergent groin hernia repair has high rates of morbidity and mortality most closely associated with increasing age and the presence of contamination. Although mesh use appears to be well tolerated when used in the absence of contamination during emergent groin hernia repair, recurrence rates were similar to tissue repairs.

Litigation Patterns in Inguinal Hernia Surgery: A 25 Year Review.

BACKGROUND: Inguinal herniorraphyis among the most common procedures performed by general surgeons, but risk factors for litigation related to this surgery are poorly defined. METHODS: Cases were retrieved by searching the Westlaw database from 1991 through 2016 using the search terms "inguinal hernia" OR "inguinal herniorrhaphy" OR "inguinal hernioplasty" and "medical malpractice." Data were compiled on the demographics of the patient, operative case details, nature of injury, legal allegations, verdicts, and indemnities. RESULTS: Forty-six cases met inclusion criteria and were selected for review. Verdicts for the defendant predominated (67%). The average plaintiff's monetary award for a plaintiff verdict or settlement was $1.21 million (median $500,000). The most frequent legal argument was improper performance (n = 35, 76%), followed by failure of informed consent (n = 14, 30%). The most common complications were nerve/chronic pain (n = 20, 45%) and testicular damage (n = 10, 23%). No association was discovered between case outcome and patient gender (P = 0.231) or age (P = 0.899). Case outcome was not different between open and laparoscopic repairs (P = 0.722). Patient mortality was not associated with case outcome (P = 0.311). There was no chronological trend in case outcome or award amount. Settlement award amounts were not significantly different than plaintiff awards (P = 0.390). CONCLUSIONS: Successful litigation after inguinal hernia surgery was relatively infrequent-only 21.7%-with an additional 10.9% resulting in settlement awards. Case outcome in litigation for hernia surgery was not predicted by patient demographics, type of procedure, or type of complication in this data set.

Operation versus watchful waiting in asymptomatic or minimally symptomatic inguinal hernias: The meta-analysis results of randomized controlled trials.

INTRODUCTION: The aim of this article was to compare and analyze the outcomes of surgical repair and watchful waiting (WW) in the treatment of asymptomatic or minimally symptomatic inguinal hernias. METHODS: A systematic literature review was undertaken to identify studies that compare surgical repair and watchful waiting in asymptomatic or minimally symptomatic inguinal hernias. And all related data matching our standards were abstracted for Meta-analysis with RevMan 5.0.1. RESULTS: Less pain was observed in Operation group. However, there were no significant differences in Physical Component Score (PCS), mortality, surgical complications and postoperative hernia recurrence between WW group and Operation group. But a great number of patients would develop significant hernia-related symptoms and cross over to surgery over time in WW group. CONCLUSIONS: Patients have relative less pain in operation group compared with WW group. Although WW is safe in patients with asymptomatic or minimally symptomatic inguinal hernias, however, this strategy would merely delay rather than avoid surgical repair of hernias in the majority of inguinal hernia patients.

Emergency department utilization and predictors of mortality for inpatient inguinal hernia repairs.

BACKGROUND: Although inguinal hernias are common surgical diagnoses, minimally symptomatic patients are often not scheduled for repairs and are asked to seek medical attention if they develop symptoms. We investigated factors associated with emergency department (ED) utilization for inguinal hernia repairs and determined whether ED utilization affected mortality for this otherwise electively treated condition. METHODS: We performed a retrospective analysis of the 2009-2013 Nationwide Inpatient Sample to identify patients who presented through the ED and were then admitted for unilateral inguinal hernia repairs. Multivariable logistic regressions that adjusted for several patient and hospital characteristics determined predictors of both ED admission and postoperative mortality. RESULTS: There were 116,357 inpatient hospitalizations. The majority (57%) resulted from ED admissions, of which most (85%) had a diagnosis of obstruction or gangrene. Notable predictors of ED admission from the multivariable analysis included obstruction (odds ratio, 9.77 [95% confidence interval: 9.05-10.55]), gangrene (18.24 [13.00-25.59]), Black race (1.47 [1.29-1.69]), Hispanic ethnicity (1.35 [1.18-1.54]), self-pay (2.29 [1.97-2.66]) and Medicaid insurance (1.76 [1.50-2.06]). While overall mortality decreased from 2.03% in 2009 to 1.36% in 2013, admission through the ED was independently associated with higher mortality compared with elective repair (1.67 [1.21-2.29]), even after adjusting for the diagnosis of obstruction and gangrene. Other predictors of mortality included patient age and comorbidities. CONCLUSIONS: In our study, Black, Hispanic, and self-pay patients were more likely to present through the ED. After adjusting for obstruction or gangrene, simply presenting through the ED was independently associated with a 67% higher postoperative mortality rate compared with that of an elective operation. Our findings suggest both a difference in ED utilization and subsequent difference in mortality by patient race and ethnicity and insurance for this common surgical condition.

Inguinal Hernias Represent the Most Frequent Surgical Complication after Kasai in Biliary Atresia Infants.

Biliary atresia (BA) is an orphan medical condition of the newborn, resulting in end-stage liver cirrhosis due to obliterative cholangiopathy of the extrahepatic bile duct. Although Kasai's hepatoportoenterostomy (KPE) is the well-established first-line therapy, little is known about its surgical complications. 153 patients receiving open KPE treated at a single center between 1994 and 2014 were analysed retrospectively regarding short-term complications and survival with the native liver. In brief, 40.5% of patients suffered from 1-3 surgical complications, inguinal hernias (IH) being most prevalent (40.0%). In BA patients, incidence of IH was associated with male gender (p = 0.002), the syndromic form of BA (p = 0.038), and percutaneous drainage for ascites (p = 0.002). No association was found with prematurity (p = 0.074) or birth weight (p = 0.912) in our study. In conclusion, IH frequently develops after open KPE of BA patients, but this complication does not negatively affect the patient's outcome. Nevertheless, inspection of the internal inguinal ring and prophylactic closure of inapparent hernias should be discussed in order to prevent secondary surgical procedures.

Unintended consequences of policy change to watchful waiting for asymptomatic inguinal hernias.

INTRODUCTION: In 2009 the Department of Health instructed McKinsey & Company to provide advice on how commissioners might achieve world class National Health Service productivity. Asymptomatic inguinal hernia repair was identified as a potentially cosmetic procedure, with limited clinical benefit. The Birmingham and Solihull primary care trust cluster introduced a policy of watchful waiting for asymptomatic inguinal hernia, which was implemented across the health economy in December 2010. This retrospective cohort study aimed to examine the effect of a change in clinical commissioning policy concerning elective surgical repair of asymptomatic inguinal hernias. METHODS: A total of 1,032 patients undergoing inguinal hernia repair in the 16 months after the policy change were compared with 978 patients in the 16 months before. The main outcome measure was relative proportion of emergency repair in groups before and after the policy change. Multivariate binary logistic regression was used to adjust the main outcome for age, sex and hernia type. RESULTS: The period after the policy change was associated with 59% higher odds of emergency repair (3.6% vs 5.5%, adjusted odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.03-2.47). In turn, emergency repair was associated with higher odds of adverse events (4.7% vs 18.5%, adjusted OR: 3.68, 95% CI: 2.04-6.63) and mortality (0.1% vs 5.4%, p<0.001, Fisher's exact test). CONCLUSIONS: Introduction of a watchful waiting policy for asymptomatic inguinal hernias was associated with a significant increase in need for emergency repair, which was in turn associated with an increased risk of adverse events. Current policies may be placing patients at risk.

Outcomes of emergent inguinal hernia repair in veteran octogenarians.

Outcomes from emergent inguinal hernia (IH) repair in veteran octogenarians are not well described. We reviewed outcomes for this cohort from 2005 to 2012 at the VA North Texas Health Care System. There were 15 emergent (Group I) and 86 elective (Group II) operations performed in octogenarians. Age and American Society of Anesthesiologists status were similar in both groups. The rate of minor and major complications was higher in Group I compared with Group II (33 and 19% vs 22 and 2%, respectively; both Ps < 0.001). Hospital length of stay (LOS) and intensive care unit LOS were also longer in Group I compared with Group II (6.7 ± 7.0 and 2.5 ± 4.4 vs 0.8 ± 1.9 and 0.12 ± 0.6 days, respectively; both Ps < 0.001). Thirty-day mortality was 13 per cent for Group I and 0 per cent for Group II. Despite the high rate of comorbid conditions in our group, the risk associated with elective repair of IH was not prohibitive. In contrast, we observed that 15 per cent of patients presented with an incarcerated hernia during the study period and the mortality rate was 13 per cent in this cohort. Factors that might predict incarceration in veteran octogenarians need to be further investigated.

Safety and efficacy of selective sac extraction method of inguinal hernia repair in children: results of a prospective study.

PURPOSE: A prospective study was conducted to confirm the safety and efficacy of the selective sac extraction method (SSEM) of inguinal hernia repairs in children. METHODS: Primary endpoints of the study were the incidence of any complication related to the SSEM, or hernia recurrence. Secondary endpoints included the success rate of the SSEM, length of incision at the end of operation, and duration of operation. The incidence of contralateral manifestation of hernia was also examined. RESULTS: Between October 2009 and December 2011, a total of 317 repairs, 145 male repairs and 172 female repairs, were performed by applying the SSEM. There were three operative conversions, and the success rate of the SSEM was 99% in both male and female patients. The length of incision ranged from 4.0 to 12.5 mm (median 6.0 mm) and was ≤7.0 mm in 93% repairs. The incisional length for male repairs ranged from 4.0 to 12.5 mm (median 6.0 mm) and was ≤7.0 mm in 86% repairs, while it ranged from 4.0 to 9.0 mm (median 5.5 mm) in female repairs and was ≤6.5 mm in 96% repairs. The duration of the operation for unilateral repair ranged from 9 to 66 min (median 21 min). Eighty percent of repairs were examined 6-44 months (median 12 months) after the operation. There was one (0.4%) recurrence among 250 repairs and two (1.7%) cases of testicular dislocation among 115 male repairs. Contralateral hernia presented in 19 (9.5%) of 199 patients with unilateral hernia who underwent the follow-up. CONCLUSIONS: The feasibility of the SSEM was reconfirmed, and it was revealed that the complication and recurrence rates were low and acceptable. The SSEM is safe and effective, and should be a standard method for repairing inguinal hernia in children.

Classifications of clinical and bowel morphological changes and their relationship with characteristics of patients with incarcerated groin hernias.

BACKGROUND: There is currently no grading standard for the degree of clinical and bowel morphological changes. The objective of this study was to define clinical and bowel morphological classifications and investigate the possible relationship with the characteristics of patients with incarcerated groin hernias. MATERIAL AND METHODS: We retrospectively studied 195 patients who underwent emergency hernia repair with simultaneous bowel resection between January 1992 and January 2012. We classified the degree of clinical and bowel morphological changes into 3 grades based on the incarceration time, intestinal morphology after damage, hernia sac integrity, degree of inflammation, and the presence/absence of bacterial growth, peritonitis signs, mechanical obstruction, cellulitis, and systemic shock. We also recorded patient characteristics and analyzed their relationships with these degrees according to our grading system. RESULTS: We identified 134, 42, and 19 cases of Grades I, II, and III of clinical and bowel morphological changes, respectively. Pearson's chi-squared tests revealed that advanced age (P=0.001), presence of comorbid disease (P=0.002), and high American Society of Anesthesiologists (ASA) score (P=0.017) were related to the degree. Morbidity and mortality also showed significant relationships with the degree (P<0.001, P=0.005, respectively), especially with regard to post-operative infection. CONCLUSIONS: The proposed 3-stage classifications of clinical and bowel morphological changes can be used to objectively reflect the degree of bowel damage. Greater levels of the changes were associated with higher incidences of complications and increased mortality, especially for older patients with comorbid diseases and poor ASA scores. Urgent surgery should be performed to avoid bowel damage exacerbation.

The totally extraperitoneal method versus Lichtenstein's technique for inguinal hernia repair: a systematic review with meta-analyses and trial sequential analyses of randomized clinical trials.

BACKGROUND: Lichtenstein's technique is considered the reference technique for inguinal hernia repair. Recent trials suggest that the totally extraperitoneal (TEP) technique may lead to reduced proportions of chronic pain. A systematic review evaluating the benefits and harms of the TEP compared with Lichtenstein's technique is needed. METHODOLOGY/PRINCIPAL FINDINGS: The review was performed according to the 'Cochrane Handbook for Systematic Reviews'. Searches were conducted until January 2012. Patients with primary uni- or bilateral inguinal hernias were included. Only trials randomising patients to TEP and Lichtenstein were included. Bias evaluation and trial sequential analysis (TSA) were performed. The error matrix was constructed to minimise the risk of systematic and random errors. Thirteen trials randomized 5404 patients. There was no significant effect of the TEP compared with the Lichtenstein on the number of patients with chronic pain in a random-effects model risk ratio (RR 0.80; 95% confidence interval (CI) 0.61 to 1.04; p = 0.09). There was also no significant effect on number of patients with recurrences in a random-effects model (RR 1.41; 95% CI 0.72 to 2.78; p = 0.32) and the TEP technique may or may not be associated with less severe adverse events (random-effects model RR 0.91; 95% CI 0.73 to 1.12; p = 0.37). TSA showed that the required information size was far from being reached for patient important outcomes. CONCLUSIONS/SIGNIFICANCE: TEP versus Lichtenstein for inguinal hernia repair has been evaluated by 13 trials with high risk of bias. The review with meta-analyses, TSA and error matrix approach shows no conclusive evidence of a difference between TEP and Lichtenstein on the primary outcomes chronic pain, recurrences, and severe adverse events.

[Quality assurance with hospital routine data in general and visceral surgery: colon and hernia surgery]. / Qualitätssicherung mit Routinedaten (QSR) in der Allgemein- und Viszeralchirurgie am Beispiel von Kolon- und Hernienoperationen.

BACKGROUND: Routine data not only allow for the mapping of a department in terms of quality-relevant aspects, but also for a comparison with other hospitals in the context of hospital associations. Currently available system options are demonstrated using the example of a department for general and visceral surgery. MATERIAL AND METHODS: Quality indicators and their algorithms have been developed by the CLINOTEL office in consultation with specialist disciplines. The base population as well as the specific criterion that stands for the unwanted event to be investigated is defined for all individual quality indicators by way of in- and exclusion criteria. In addition, case reports are transmitted; these are lists of relevant case data, which are prepared as soon as at least one quality indicator has been identified from the analysis of the case data (screening function). RESULTS: A total of 16 case reports were generated for 251 cases of hernia, which corresponds to 6.4%. There were 21 case reports for 58 colon resections (36.2%). 5 cases of hernia and 11 cases from the group of colon resections were presented in M&M conferences, in the course of which measures to prevent unwanted events during colon and hernia surgery were developed. A part of these measures was also the introduction of a "for immediate medical attention" checklist, containing a list of clinical symptoms that in our view require the immediate attention of a doctor. Previously, our M&M conference had no defined "script" that would include questions in need of urgent attention and therefore of urgent answers. However, the complexity of individual cases has shown that the conferences must acquire a more formalised format. CONCLUSION: QSR constitutes an important information channel with a positive cost-benefit ratio for department managers of surgical clinics. The information gained can be used for clinical quality monitoring and also for the screening of conspicuous courses of treatment. Taking into account the intrinsic limitations of classification systems for diagnoses and procedures, and a systematic monitoring of documentation and coding quality, this should result in a continuous improvement process in terms of surgical care.

Complicated childhood inguinal hernias in UITH, Ilorin.

BACKGROUND: Complicated inguinal hernias pose a threat to the life of the child as well as increase the morbidity associated with management of an otherwise straightforward condition. The aim of this study was to determine the presentation, treatment and management outcome of complicated inguinal hernias in children. MATERIALS AND METHODS: A retrospective study of all children 15 years and less managed for complicated inguinal hernia between 2002 and 2010. Data obtained included demographic characteristics, presentation, operative findings and outcome. RESULTS: Complicated hernia rate was 13.9%.There were 41 children, 38 boys (92.7%) and 3 girls. Ages ranged between 4 days and 15 years (Median = 90days). Most were infants (48.8%, n = 20) and neonates accounted for 19.5% (n = 8). Median duration of symptoms prior to presentation was 18 h (range = 2-96 h). Seven patients had been scheduled for elective surgery. Hernia was right sided in 68.3% (n = 28). Symptoms included vomiting (68.3%), abdominal distension (34.1%) and constipation (4.9%); one patient presented with seizures. In 19 (46.3%) patients hernia was reducible while 22(53.7%) had emergency surgery. Associated anomalies included undescended testis (12.2%), umbilical hernia (14.6%). Intestinal resection rate was 7.3% and testicular gangrene occurred in 14.6%. Mean duration of surgery was 60.3 ± 26.7 min. Wound infection occurred in six patients (14.6%). Overall complication rate was 24.4%, 30% in infants. The mortality rate was 2.4% (n = 1). CONCLUSIONS: Morbidity associated with complicated inguinal hernia is high in neonates and infants. Delayed presentation is common in our setting. Educating the parents as well as primary care physicians on the need for early presentation is necessary.

Surgical management of inguinal hernias at Bugando Medical Centre in northwestern Tanzania: our experiences in a resource-limited setting.

BACKGROUND: Inguinal hernia repair remains the commonest operation performed by general surgeons all over the world. There is paucity of published data on surgical management of inguinal hernias in our environment. This study is intended to describe our own experiences in the surgical management of inguinal hernias and compare our results with that reported in literature. METHODS: A descriptive prospective study was conducted at Bugando Medical Centre in northwestern Tanzania. Ethical approval to conduct the study was obtained from relevant authorities before the commencement of the study. Statistical data analysis was done using SPSS software version 17.0. RESULTS: A total of 452 patients with inguinal hernias were enrolled in the study. The median age of patients was 36 years (range 3 months to 78 years). Males outnumbered females by a ratio of 36.7:1. This gender deference was statistically significant (P=0.003). Most patients (44.7%) presented late (more than five years of onset of hernia). Inguinoscrotal hernia (66.8%) was the commonest presentation. At presentation, 208 (46.0%) patients had reducible hernia, 110 (24.3%) had irreducible hernia, 84 (18.6%) and 50(11.1%) patients had obstructed and strangulated hernias respectively. The majority of patients (53.1%) had right sided inguinal hernia with a right-to-left ratio of 2.1: 1. Ninety-two (20.4%) patients had bilateral inguinal hernias. 296 (65.5%) patients had indirect hernia, 102 (22.6%) had direct hernia and 54 (11.9%) had both indirect and direct types (pantaloon hernia). All patients in this study underwent open herniorrhaphy. The majority of patients (61.5%) underwent elective herniorrhaphy under spinal anaesthesia (69.2%). Local anaesthesia was used in only 1.1% of cases. Bowel resection was required in 15.9% of patients. Modified Bassini's repair (79.9%) was the most common technique of posterior wall repair of the inguinal canal. Lichtenstein mesh repair was used in only one (0.2%) patient. Complication rate was 12.4% and it was significantly higher in emergency herniorrhaphy than in elective herniorrhaphy (P=0.002). The median length of hospital stay was 8 days and it was significantly longer in patients with advanced age, delayed admission, concomitant medical illness, high ASA class, the need for bowel resection and in those with surgical repair performed under general anesthesia (P<0.001). Mortality rate was 9.7%. Longer duration of symptoms, late hospitalization, coexisting disease, high ASA class, delayed operation, the need for bowel resection and presence of complications were found to be predictors of mortality (P<0.001). CONCLUSION: Inguinal hernias continue to be a source of morbidity and mortality in our centre. Early presentation and elective repair of inguinal hernias is pivotal in order to eliminate the morbidity and mortality associated with this very common problem.
