The Prevalence and Characteristics of Untreated Hernias in Southwest Cameroon.

BACKGROUND: Hernias are one of the most commonly encountered surgical conditions, and every year, more than 20 million hernia repairs are performed worldwide. The surgical management of hernia, however, is largely neglected as a public health priority in developing countries, despite its cost-effectiveness. To date, the prevalence and impact of hernia have not been formally studied in a community setting in Cameroon. The aim of this study was to determine the prevalence and characteristics of untreated hernia in the Southwest region of Cameroon. METHODS: This study was a subanalysis of a cross-sectional community-based survey on injury in Southwest Cameroon. Households were sampled using a three-stage cluster sampling method. Household representatives reported all untreated hernias occurring in the past year. Data on socioeconomic factors, hernia symptoms, including the presence of hernia incarceration, and treatment attempts were collected between January 2017 and March 2017. RESULTS: Among 8065 participants, 73 persons reported symptoms of untreated hernia, resulting in an overall prevalence of 7.4 cases per 1000 persons (95% confidence limit 4.98-11.11). Groin hernias were most commonly reported (n = 49, 67.1%) and predominant in young adult males. More than half of persons with untreated hernia (56.7%) reported having symptoms of incarceration, yet 42.1% (n = 16) of these participants did not receive any surgical treatment. Moreover, 21.9% of participants with untreated hernias never presented to formal medical care, primarily because of the high-perceived cost of care. Untreated hernias caused considerable disability, as 21.9% of participants were unable to work because of their symptoms, and 15.1% of households earned less money. CONCLUSIONS: Hernia is a significant surgical problem in Southwest Cameroon. Despite over half of those with unrepaired hernias reporting symptoms of incarceration, home treatment and nonsurgical management were common. Costs associated with formal medical services are a major barrier to obtaining consultation and repair. Greater awareness of hernia complications and cost restructuring should be considered to prevent disability and mortality due to hernia.

Prevalence and Cost Analysis of Chronic Pain After Hernia Repair: A Potential Alternative Approach With Neurostimulation.

OBJECTIVES: Chronic pain (CP) affects a significant number of patients following hernia repair, ranging from 11 to 54% in the literature. The aim of this study was to assess the prevalence, overall costs, and health care utilization associated with CP after hernia repair. MATERIALS AND METHODS: A retrospective longitudinal study was performed using the Truven MarketScan® data base to identify patients who develop chronic neuropathic posthernia repair pain from 2001 to 2012. Patients were grouped into CP and No Chronic Pain (No CP) cohorts. Patients were excluded if they 1) were under 18 years of age; 2) had a previous pain diagnosis; 3) had CP diagnosed <90 days after the index hernia repair; 4) had less than one year of follow-up; or 5) had less than one-year baseline record before hernia repair. Patients were grouped into the CP cohort if their CP diagnosis was made within the two years following index hernia repair. Total, outpatient, and pain prescription costs were collected in the period of five years prehernia to nine years posthernia repair. A longitudinal multivariate analysis was used to model the effects of chronic neuropathic posthernia repair pain on total inpatient/outpatient and pain prescription costs. RESULTS: We identified 76,173 patients who underwent hernia repair and met inclusion criteria (CP: n = 14,919, No CP: n = 61,254). There was a trend for increased total inpatient/outpatient and pain prescription costs one-year posthernia repair, when compared to baseline costs for both cohorts. In both cohorts, total inpatient/outpatient costs remained elevated from baseline through nine years posthernia repair, with the CP cohort experiencing significantly higher cumulative median costs (CP: $51,334, No CP: $37,388). The CP diagnosis year was associated with a 1.75-fold increase (p < 0.001) in total inpatient/outpatient costs and a 2.26-fold increase (p < 0.001) in pain prescription costs versus all other years. In the longitudinal analysis, the CP cohort had a 1.14-fold increase (p < 0.001) in total inpatient/outpatient costs and 2.00-fold increase (p < 0.001) in pain prescription costs. CONCLUSIONS: Our study demonstrates the prevalence of CP after hernia surgery to be nearly 20%, with significantly increased costs and healthcare resource utilization. While current treatment paradigms are effective for many, there remains a large number of patients that could benefit from an overall approach that includes nonopioid treatments, such as potentially incorporating neurostimulation, for CP that presents posthernia repair.

Sustainability in humanitarian surgery during medical short-term trips (MSTs): feasibility of inguinal hernia repair in rural Nigeria over 6 years and 13 missions.

PURPOSE: Surgical teaching missions are known to contribute significantly in reducing the local burden of disease. However, the value of short-term medical service trips (MSTs) remains under debate. Humanitarian surgery is highly dependent on funding, and consequently, data evaluation is needed to secure funding for future projects. The aim of this trial is to evaluate the results of 6-year MSTs to rural Nigeria with a specific emphasis on hernia repairs. METHODS: Retrospective series of consecutive operations performed between 2011 and 2016 in rural Nigeria during 13 MSTs. Operations were categorized into type and number of procedures and origin of the surgeon. In terms of inguinal hernia repairs additional data was evaluated such as frequency of local anaesthesia (LA) and the type of hernia. The total amount of disability-adjusted life years (DALYs) averted during each mission are presented and discussed with regard to sustainability of these missions. RESULTS: From 2011 to 2016, a total of 1674 patients were operated. Of these, 1302 patients were operated for 1481 hernias of which 36.7% accounting as inguinoscrotal hernias. The percentage of operations performed by Nigerian staff increased from 31 to 55%. Overall, eighteen percent of the operations was solely performed by Nigerians. Totally, we averted 8092.83 DALY's accounting for 5.46 DALY's per hernia. CONCLUSION: The presented missions contribute significantly to an improvement in local healthcare and decrease the burden of disease. We were able to show the sustainable character of these surgical missions. As a next step, we will analyse the cost-effectiveness of MSTs.

Cost effectiveness of laparoscopic versus open mesh hernia operation: results of a Department of Veterans Affairs randomized clinical trial.

BACKGROUND: Evidence comparing laparoscopic versus open hernia repair has varied with time and with changes in techniques used. Cost effectiveness is an important consideration when evidence for predominance of one surgical technique is lacking. Current cost estimates of hernia repair are not available. STUDY DESIGN: This study is a cost effectiveness analysis within a randomized controlled trial comparing open (OPEN) versus laparoscopic (LAP) hernia repair using mesh at 14 Department of Veterans Affairs medical centers, with 2-year followup for each patient. Between January 1999 and November 2001, 2,164 men with inguinal hernia were randomized and 1,983 had an operation; 1,395 patients (708 OPEN and 687 LAP) with outpatient hernia operations were included in the cost effectiveness analysis. Outcomes included surgical and postoperative costs, quality adjusted life years (QALY), and incremental cost per QALY gained or the incremental cost effectiveness ratio (ICER). RESULTS: Over 2 years, LAP cost an average of $638 more than OPEN. QALYs at 2 years were similar, resulting in $45,899 per QALY gained (95% CI: -$669,045, $722,457). The probability that LAP is cost effective at the $50,000 per QALY level (slightly more costly but more effective), was 51%. For unilateral primary and unilateral recurrent hernia repair, the probabilities that LAP is cost effective at the $50,000 per QALY level were 64% and 81%, respectively. For bilateral hernia repair, OPEN was less costly and more effective. CONCLUSIONS: Overall, laparoscopic hernia repair is not cost effective compared with open repair. For patients with unilateral (primary or recurrent) hernia, laparoscopic repair is a cost effective treatment option.

Cirugía ambulatoria sin ingreso en patología herniaria / Ambulatory surgery without entrance in herniation pathology

Objetivos: nuestro servivio quirúrgico hizo una revisión que analiza los resultados, los criterios de selección y las técnicas utilizadas en nuestro Programa de Cirugía Ambulatoria de las Hernias. Pacientes y métodos: se trataron 195 pacientes entre julio de 1997 y diciembre de 2001. Las técnicas utilizadas con colocación de mallas o sin ellas variaron de acuerdo con los defectos parietales que se proponían solucionar. Se usaron rígidos criterios de exclusión (grandes hernias, riesgo ASA alto, factores adversos psicosociales). Resultados: sólo en un caso debimos internar al paciente y abandonar el programa, operamos un 60 por ciento de hernias inguinales directas, y nuestra morbilidad fue de aproximadamente 14 por ciento, lo que es igual a la morbilidad del tratamiento de las hernias con internación. Discusión: hicimos el tratamiento de la mayoría de nuestros pacientes en forma ambulatoria, con una morbilidad semejante y menor costo

Epidemiologic, economic, and sociologic aspects of hernia surgery in the United States in the 1990s.

Such important, yet basic, questions as the percentage chance that an individual will over the course of his or her life be in need of or actually undergo a groin herniorrhaphy or the absolute number and type of hernias that exist in a given society on any particular day continue to be statistically undefined. A review of epidemiologic data provides come preliminary answers. Recent studies from the National Center for Health Statistics show that approximately 750,000 groin herniorrhaphies are completed annually in the United States. More than 80% of these operations involve the use of mesh prosthesis and are performed on an outpatient basis. Despite the large number of hernioplasties completed, the public's understanding of hernias and their management remains unsophisticated.

Demographic, classificatory, and socioeconomic aspects of hernia repair in the United States.

Although demographic and socioeconomic data regarding the natural history of hernia disease are difficult to find, studies from the National Center for Health Statistics show that approximately 700,000 groin herniorrhaphies are completed annually in the United States. More than 60% of these operations are performed on an outpatient basis. Classification schemes relative to hernia repair serve as an important communication tool when retrieving and reporting operative results in a more comprehensive, reliable, and meaningful fashion. Part of the growing movement toward ambulatory surgery includes the construction of office-based operating suites by general surgeons. Because of the increasing number of hernioplasties completed in the outpatient setting, the use of a laparoscopic approach for hernia repair does not appear to provide any cost-saving benefits over existing conventional techniques.
