<abstract><sec><title>Background</title>
<p>Inguinal hernia affects approximately 27&#x0025; of men and 3&#x0025; of women, with prevalence rising markedly after age 65 due to weakened abdominal walls and comorbidities such as chronic obstructive pulmonary disease and benign prostatic hyperplasia, which increase intra-abdominal pressure. Standard treatment involves surgical repair using either open or laparoscopic techniques. However, the optimal approach for elderly patients remains debated due to higher comorbidity rates and unique physiological considerations. This study compares outcomes of laparoscopic and open inguinal hernia repair in patients aged &#x2265;65 years to support evidence-based surgical decision-making.</p>
</sec><sec><title>Methods</title>
<p>We conducted a retrospective analysis of 384 patients aged &#x2265;65 years who underwent inguinal hernia repair at the Second Affiliated Hospital of Dalian Medical University between 2020 and 2022. Patients were classified into laparoscopic (<italic>n</italic>&#x2009;&#x003D;&#x2009;197) and open (<italic>n</italic>&#x2009;&#x003D;&#x2009;187) repair groups. Demographics, operative details, and postoperative outcomes were compared using chi-square tests, Mann&#x2013;Whitney <italic>U</italic> tests, and multivariable logistic regression (SPSS v27), with statistical significance set at <italic>p</italic>&#x2009;&#x003C;&#x2009;0.05.</p>
</sec><sec><title>Results</title>
<p>The laparoscopic cohort was younger [median 70 (65&#x2013;91) vs. 75 (65&#x2013;98) years; <italic>p</italic>&#x2009;&#x003C;&#x2009;0.001], had a higher prevalence of bilateral hernias (25.9&#x0025; vs. 4.3&#x0025;; <italic>p</italic>&#x2009;&#x003C;&#x2009;0.001), and smaller hernia sacs [2.50 (1&#x2013;5) cm vs. 3 (1&#x2013;5) cm; <italic>p</italic>&#x2009;&#x003C;&#x2009;0.001]. Although operative time was longer for laparoscopy [76 (40&#x2013;120) vs. 60 (40&#x2013;115) minutes; <italic>p</italic>&#x2009;&#x003C;&#x2009;0.001], it was associated with fewer postoperative complications, shorter hospital stays, and lower chronic pain rates (all <italic>p</italic>&#x2009;&#x003C;&#x2009;0.01). Multivariable logistic regression identified open repair as an independent risk factor for complications (OR&#x2009;&#x003D;&#x2009;0.359; <italic>p</italic>&#x2009;&#x003D;&#x2009;0.012) and chronic pain (OR&#x2009;&#x003D;&#x2009;0.258; <italic>p</italic>&#x2009;&#x003D;&#x2009;0.009). Patients in the laparoscopic group also resumed normal activities sooner.</p>
</sec><sec><title>Conclusion</title>
<p>Although laparoscopic inguinal hernia repair requires a longer operative time, it offers superior outcomes in elderly patients, including fewer complications, reduced chronic pain, and faster recovery. Careful patient selection based on age, hernia characteristics, and overall health is essential; however, when feasible, laparoscopy should be considered the preferred approach to optimize outcomes in this population.</p>

<p>An inguinal hernia is an abdominal wall defect occurring in the groin region (<xref ref-type="bibr" rid="B1">1</xref>, <xref ref-type="bibr" rid="B2">2</xref>) and is one of the most common surgical conditions worldwide, with approximately 20 million repairs performed annually (<xref ref-type="bibr" rid="B3">3</xref>). The prevalence increases with age, from 0.25&#x0025; at 18 years to 4.2&#x0025; between 75 and 80 years (<xref ref-type="bibr" rid="B4">4</xref>). In the United States, more than 800,000 inguinal hernias are repaired each year (<xref ref-type="bibr" rid="B5">5</xref>, <xref ref-type="bibr" rid="B6">6</xref>). In China, 14.19&#x0025; of the population is aged &#x2265;65 years, slightly above the global average (<xref ref-type="bibr" rid="B7">7</xref>) and hernia incidence is increasing. Between 1990 and 2019, India, China, and Brazil accounted for 39&#x0025; of global cases, with China reporting 1.95 million cases during this period (<xref ref-type="bibr" rid="B8">8</xref>). Given this increasing prevalence in elderly populations, understanding the optimal surgical approach becomes crucial, as patient age and associated comorbidities significantly influence treatment decisions and outcomes.</p>
<p>Factors associated with an increased risk of developing an inguinal hernia include male sex, advanced age, low body mass index, prior prostate surgery, systemic connective tissue disorders, previous radiation therapy, and a family history of hernias, as indicated by epidemiological studies (<xref ref-type="bibr" rid="B9">9</xref>). The first incidence peak occurs during infancy, while the second is seen in the fourth decade of life (<xref ref-type="bibr" rid="B10">10</xref>). Men have a higher lifetime prevalence of inguinal hernias than women, ranging from 27&#x0025;&#x2013;43&#x0025; (<xref ref-type="bibr" rid="B11">11</xref>). It is also more common in elderly adults due to diminished abdominal wall strength and other medical conditions that increase intra-abdominal pressure, notably chronic obstructive pulmonary disease and benign prostatic hyperplasia (<xref ref-type="bibr" rid="B12">12</xref>).</p>
<p>Patients with inguinal hernia typically present with a groin bulge that may gradually enlarge over time (<xref ref-type="bibr" rid="B9">9</xref>). While urgent surgical intervention is required in certain situations, most cases are managed electively (<xref ref-type="bibr" rid="B13">13</xref>). Emergency surgery is indicated when there is sudden, severe abdominal pain suggestive of incarceration (<xref ref-type="bibr" rid="B14">14</xref>). Compared with younger individuals, elderly patients experience higher rates of postoperative mortality and morbidity (<xref ref-type="bibr" rid="B15">15</xref>, <xref ref-type="bibr" rid="B16">16</xref>). Although older adults with comorbidities may have minimal symptoms and relatively low short-term risk, the optimal timing for intervention remains uncertain (<xref ref-type="bibr" rid="B17">17</xref>). Some researchers recommend early elective repair in elderly patients with comorbidities, whereas others support close monitoring in young, otherwise healthy individuals (<xref ref-type="bibr" rid="B18">18</xref>, <xref ref-type="bibr" rid="B19">19</xref>). Notably, a Swedish study reported that the mortality rate for elective hernia repair is low, even among patients over 80 years of age (0.58&#x0025;) (<xref ref-type="bibr" rid="B20">20</xref>). Surgical repair remains the most effective treatment for inguinal hernia (<xref ref-type="bibr" rid="B21">21</xref>).</p>
<p>The choice between open repair and laparoscopic mesh repair depends on patient characteristics, anticipated operative time, and complication risk (<xref ref-type="bibr" rid="B4">4</xref>). Over the past two decades, numerous studies have compared these approaches (<xref ref-type="bibr" rid="B8">8</xref>). The Lichtenstein open mesh repair is a well-established technique with a recurrence rate below 1&#x0025; (<xref ref-type="bibr" rid="B22">22</xref>), but chronic pain remains a notable complication, affecting 5&#x0025;&#x2013;10&#x0025; of patients and reported in up to 63&#x0025; of cases (<xref ref-type="bibr" rid="B23">23</xref>). Since the introduction of laparoscopic techniques by Watson et al. in 1993 (<xref ref-type="bibr" rid="B24">24</xref>). Debate has continued regarding their advantages and disadvantages, particularly in elderly patients. Laparoscopic inguinal hernia repair (LIHR) has gained popularity worldwide due to advances in minimally invasive surgery, offering reduced wound complications, lower recurrence rates, and faster recovery (<xref ref-type="bibr" rid="B25">25</xref>&#x2013;<xref ref-type="bibr" rid="B27">27</xref>). However, open repair remains necessary in patients with coagulopathy, significant preperitoneal adhesions, or extraperitoneal hemorrhage (<xref ref-type="bibr" rid="B28">28</xref>). In elderly patients with poor cardiopulmonary reserve or intolerance to general anesthesia, open repair under regional anesthesia is generally preferred (<xref ref-type="bibr" rid="B29">29</xref>).</p>
<p>This study seeks to determine the optimal surgical approach for managing inguinal hernias in patients aged &#x2265;65 years. In surgical research, outcomes refer to measurable clinical results following an intervention, including postoperative complications, chronic pain, length of hospital stay, recovery time, and recurrence rates (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B11">11</xref>, <xref ref-type="bibr" rid="B30">30</xref>). Evaluating these outcomes provides objective evidence to guide the selection between open and laparoscopic inguinal hernia repair, particularly in elderly patients. Therefore, we conducted a retrospective analysis to compare the clinical outcomes of laparoscopic and open inguinal hernia repair in this population.</p>

<sec id="s2a"><label>2.1</label><title>Study design and participants</title>
<p>This study was performed as a retrospective comparative analysis. A total of 384 patients with inguinal hernia, including both indirect and direct types, underwent elective surgical intervention. Patients admitted to the Department of Colorectal and Hernia Surgery at the Second Affiliated Hospital of Dalian Medical University between 2020 and 2022 were selected. The research protocol received approval from the Medical Ethics Committee of the Second Affiliated Hospital of Dalian Medical University and complied with the ethical principles established in the Declaration of Helsinki. The retrospective design of the study removed the necessity for written informed consent from the patients involved.</p>

<sec id="s2b"><label>2.2</label><title>Study population and inclusion &#x0026; exclusion criteria</title>
<p>All patients were categorized who underwent elective inguinal hernia repair at the Second Affiliated Hospital of Dalian Medical University between January 2020 and June 2022 into two groups: group A (open approach) and group B (laparoscopic approach).</p>

<sec id="s2c"><label>2.3</label><title>Data collection</title>
<p>We abstracted data from the electronic medical records using a standardized form. Baseline variables included age, sex, body mass index, tobacco and alcohol use, and American Society of Anesthesiologists (ASA) classification, which was dichotomized as grades I&#x2013;II vs. III&#x2013;IV. Comorbidities were recorded individually and comprised coronary artery disease, diabetes mellitus, hypertension, congestive heart failure, atrial fibrillation, chronic obstructive pulmonary disease, cerebrovascular disease, and benign prostatic hyperplasia. Hernia-related characteristics included site (unilateral/bilateral), type (indirect/direct), overall hernia size, and sac size.</p>
<p>Perioperative variables encompassed surgical approach [open vs. laparoscopic (TAPP or TEP)], type of anesthesia, operative time, mesh use, estimated blood loss, intraoperative intravenous fluid volume, and urine output. Postoperative endpoints included the occurrence of complications, specifically surgical-site infection, seroma, hematoma, and delirium, each recorded as present or absent. We also captured length of hospital stay, the presence of chronic pain, time to return to normal activities or work, and hernia recurrence.</p>
<p>All patients were followed at approximately 1, 6, and 12 months after surgery, either in outpatient clinic visits or by telephone interview. At each contact, we ascertained recurrence status, chronic pain, and return-to-activity timing. For missing data, we applied a complete-case approach: patients lacking information for a given primary endpoint (e.g., no 12-month recurrence assessment) were excluded from the analysis of that endpoint but retained in analyses for which their data were complete. No statistical imputation was performed.</p>

<sec id="s3"><label>3</label><title>Statistical analysis</title>
<p>Data analysis was conducted using IBM SPSS version 27 (IBM Corp., Armonk, NY) and GraphPad version 8. Continuous variables were analyzed by calculating medians, while categorical variables were assessed using frequencies and percentages. The distribution of numerical variables was assessed using the Shapiro&#x2013;Wilk test, indicating an abnormal distribution and confirming the appropriateness of non-parametric testing. Medians and non-parametric independent tests, specifically the Mann&#x2013;Whitney <italic>U</italic> test, were utilized for analysis. We utilized chi-square analysis or Fisher&#x0027;s exact test to compare categorical data, contingent upon the number of participants in each category. We conducted univariate and multivariate binary logistic regression analyses to identify predictive factors. A <italic>p</italic>-value less than 0.05 was deemed statistically significant in the statistical analyses.</p>

<p>This study enrolled 384 patients who underwent elective inguinal hernia surgery. Of these, 187 (48.6&#x0025;) underwent open surgery, while 197 (51.4&#x0025;) received laparoscopic procedures. The median age was significantly lower in the laparoscopic hernia repair group compared to the open hernia repair group (<italic>P</italic>&#x2009;&#x003C;&#x2009;0.001) (<xref ref-type="fig" rid="F3">Figure&#x00A0;3A</xref>). No statistically significant distinction was observed in gender treated with either open or laparoscopic hernia repair groups, in which the male gender represented the majority of cases in both groups (92.5&#x0025; and 91.4&#x0025;, respectively, <italic>P</italic>&#x2009;&#x003D;&#x2009;0.681) (<xref ref-type="fig" rid="F3">Figure&#x00A0;3B</xref>).

<sec id="s4c"><label>4.3</label><title>Potential factors influencing the selection of surgical approach for hernia repair</title>
<p>To further investigate the significance of our comparative analysis findings, we conducted binary univariate logistic regression to identify factors associated with surgical approach selection. The regression analysis revealed several significant predictors that influenced the choice between laparoscopic and open-surgical techniques (<xref ref-type="table" rid="T4">Table&#x00A0;4</xref>). Subsequent multivariate logistic regression analysis demonstrated that age remained a significant predictor (OR&#x2009;&#x003D;&#x2009;0.881, 95&#x0025; CI: 0.838&#x2013;0.926, <italic>P</italic>&#x2009;&#x003C;&#x2009;0.001), indicating that laparoscopic procedures were more prevalent among younger patients. The hernia site emerged as a strong predictor (OR&#x2009;&#x003D;&#x2009;11.588, 95&#x0025; CI: 3.956&#x2013;33.944, <italic>P</italic>&#x2009;&#x003C;&#x2009;0.001). The size of the hernia sac also significantly influenced surgical choice (OR&#x2009;&#x003D;&#x2009;0.620, 95&#x0025; CI: 0.442&#x2013;0.872, <italic>P</italic>&#x2009;&#x003D;&#x2009;0.006), with smaller hernias being more frequently addressed laparoscopically.</p>

This analysis confirmed that open hernia repair represented an independent risk factor for the development of chronic pain (OR&#x2009;&#x003D;&#x2009;0.258, 95&#x0025; CI: 0.093&#x2013;0.714, <italic>P</italic>&#x2009;&#x003D;&#x2009;0.009). Subsequently, we observed that patients experiencing chronic pain demonstrated significantly delayed return to work times, suggesting that post-operative pain may be a determining factor in recovery and resumption of normal activities (OR&#x2009;&#x003D;&#x2009;1.078, 95&#x0025; CI: 0.997&#x2013;1.165, <italic>P</italic>&#x2009;&#x003D;&#x2009;0.059) (<xref ref-type="table" rid="T5">Table&#x00A0;5</xref>).</p>

<p>Analysis of factors influencing operation time revealed several significant associations through univariable analysis. Initial findings indicated that surgical approach, age, hernia site, and type of anesthesia demonstrated significant relationships with operative duration. Subsequent multivariable regression analysis identified two independent predictors of prolonged operation time: hernia size (OR&#x2009;&#x003D;&#x2009;1.550, 95&#x0025; CI: 1.111&#x2013;2.161, <italic>P</italic>&#x2009;&#x003D;&#x2009;0.010) and the presence of hypertension (OR&#x2009;&#x003D;&#x2009;0.270, 95&#x0025; CI: 0.102&#x2013;0.713, <italic>P</italic>&#x2009;&#x003D;&#x2009;0.008) (<xref ref-type="table" rid="T6">Table&#x00A0;6</xref>).</p>

<p>The surgical management of inguinal hernia remains a significant healthcare challenge, with over 20 million procedures performed annually worldwide, representing 75&#x0025; of all abdominal wall hernias (<xref ref-type="bibr" rid="B16">16</xref>). The condition disproportionately affects males (27&#x0025;) compared to females (3&#x0025;) (<xref ref-type="bibr" rid="B31">31</xref>), with increasing prevalence anticipated as global demographics shift toward an aging population (<xref ref-type="bibr" rid="B32">32</xref>). Despite the high frequency of inguinal hernia repair among elderly patients (aged 65 and older) (<xref ref-type="bibr" rid="B33">33</xref>), there remains a notable research gap regarding the optimal surgical approach for this demographic. The objective of this investigation is to assess the comparative effectiveness of laparoscopic and open hernia repair in elderly patients.</p>
<p>Our comparative analysis of open and laparoscopic inguinal hernia repair groups revealed several significant findings. Notably, neither group experienced mortality, and laparoscopic intervention demonstrated fewer complications, reduced chronic pain, and faster recovery times, consistent with previous research (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B29">29</xref>, <xref ref-type="bibr" rid="B34">34</xref>, <xref ref-type="bibr" rid="B35">35</xref>). These advantages likely stem from smaller surgical incisions and improved postoperative wound healing dynamics. Our findings align with earlier studies (<xref ref-type="bibr" rid="B36">36</xref>), examining open preperitoneal inguinal hernia repair outcomes.</p>
<p>The study identified significant correlations between open inguinal hernia repair and various parameters, including age, hernia site, hernia sac size, hospital stay duration, and operation time. While laparoscopic repair offers numerous advantages (<xref ref-type="bibr" rid="B37">37</xref>), it typically requires longer operative times, reflecting the established learning curve for surgeons adopting these techniques (<xref ref-type="bibr" rid="B30">30</xref>). Extended operative duration in laparoscopy may result in elevated expenses attributable to factors such as increased consumption of surgical supplies, prolonged anesthesia duration, and extended hospital admissions. Although laparoscopy typically incurs lower overall costs relative to open surgery due to diminished hospital stays and expedited recovery, an elongated laparoscopic procedure can undermine some of these advantages (<xref ref-type="bibr" rid="B38">38</xref>). Although all procedures were performed by the same team of senior surgeons, the extended operation time in the laparoscopic group may be attributed to additional patient preparation and port placement requirements.</p>
<p>Contrary to previous studies highlighting concerns about anticoagulant and thrombolytic medications affecting bleeding tendencies in elderly patients (<xref ref-type="bibr" rid="B28">28</xref>, <xref ref-type="bibr" rid="B39">39</xref>, <xref ref-type="bibr" rid="B40">40</xref>). Our analysis showed no significant differences in bleeding or hematoma formation between approaches, possibly due to effective preoperative medication management. Laparoscopic inguinal hernia repair (LIHR) demonstrated several advantages, including reduced intraoperative blood loss, shorter hospital stays, and quicker return to normal activities compared to open repair (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B41">41</xref>). The study identified LIHR as an independent factor in reducing postoperative pain, consistent with previous research showing minimal chronic pain following laparoscopic repair (<xref ref-type="bibr" rid="B42">42</xref>).</p>
<p>A crucial factor is the anesthetic requirement, LIHR generally requires general anesthesia, but OIHR may be conducted under local or regional anesthesia, rendering it more acceptable for patients who are not candidates for general anesthesia (<xref ref-type="bibr" rid="B43">43</xref>). In our cohort, all laparoscopic repairs (100&#x0025;) were executed under general anesthesia, whereas the majority of open repairs (86.6&#x0025;) were carried out under local or regional anesthesia. No postoperative cardiovascular problems were seen in either group (0&#x0025; vs. 0&#x0025;). This finding contrasts with earlier reports suggesting that regional anesthesia in elderly patients may increase the risk of cardiac and thromboembolic events (<xref ref-type="bibr" rid="B16">16</xref>). In addition other extensive research, such as Mayer et al. (2016), which indicated that cardiovascular or thromboembolic problems occurred in 1.2&#x0025;&#x2013;1.8&#x0025; of older patients having inguinal hernia surgery with regional anesthesia (<xref ref-type="bibr" rid="B17">17</xref>). Wang et al. (2024) recently showed that ultrasound-guided local nerve block mitigated cardiopulmonary impairment, with cardiovascular events occurring in less than 1&#x0025; of older individuals (<xref ref-type="bibr" rid="B44">44</xref>). In contrast to the stated rates, our result of 0&#x0025; problems indicates that thorough preoperative cardiac assessment and meticulous anesthetic selection may have enhanced perioperative safety in our patient cohort, and maybe due to small sample size.</p>
<p>This study has limitations inherent to its retrospective, single-center design. The modest sample size (<italic>n</italic>&#x2009;&#x003D;&#x2009;384), reliance on medical-record abstraction, and involvement of multiple surgeons may introduce measurement variability and limit external validity. Importantly, the surgical approach (open vs. laparoscopic) was determined by clinical judgment rather than randomization; therefore, selection bias (confounding by indication) is possible. Although we adjusted for age, ASA class, hernia characteristics, anesthesia type, and major comorbidities, residual confounding from unmeasured factors cannot be excluded. In addition, 12-month follow-up may underdetect late recurrences and long-term pain outcomes. These constraints support the need for prospective, multicenter studies ideally randomized or using propensity-based methods with longer follow-up and standardized complication grading.</p>
</sec>
<sec id="s6" sec-type="conclusions"><label>6</label><title>Conclusion</title>
<p>This study confirms that laparoscopic inguinal hernia repair provides superior postoperative outcomes compared to the open approach in patients aged 65 years and older, including reduced complication rates, decreased chronic pain, and shorter hospital stays. Key determinants of surgical outcomes were hernia sac size, anatomical location, and anesthesia type, with complex hernias requiring advanced surgical expertise and individualized anesthetic planning. Although laparoscopic repair was associated with longer operative times, open surgery emerged as an independent risk factor for chronic postoperative pain.</p>
<p>From a clinical governance perspective, these findings support the integration of laparoscopic repair as the preferred approach for eligible elderly patients into institutional surgical guidelines. Hospitals could consider adopting structured preoperative assessment protocols to optimize patient selection particularly evaluating comorbidities, anesthetic tolerance, and hernia complexity to ensure both safety and effectiveness. Furthermore, given the long-term benefits for patient recovery and reduced resource utilization, investment in laparoscopic training and equipment may align with broader hospital policy goals of improving surgical quality metrics and cost efficiency.</p>
<p>Future multicenter prospective studies with larger elderly cohorts will be valuable for refining these recommendations and potentially informing national guidelines on inguinal hernia management in this high-risk population.</p>
