To develop a nomogram model for predicting contralateral patent processus vaginalis in children with unilateral inguinal hernia or hydrocele. A retrospective analysis was conducted on 259 children with unilateral inguinal hernia or hydrocele who underwent laparoscopic surgery at the Southern Hospital of Southern Medical University from January 2021 to December 2023. The patients were randomly divided into a training set (n = 207) and a validation set (n = 52) in an 8:2 ratio to analyze the characteristics of CPPV. Multivariate logistic regression analysis was used to screen for independent risk factors for CPPV, and a nomogram prediction model was constructed. The predictive ability, calibration, and clinical net benefit of the model were evaluated by plotting receiver operating characteristic (ROC) curves, calibration curves (HL), and clinical decision curves (DCA). Among children under 1 year old, the laparoscopic exploration revealed a CPPV incidence rate of 55.17%. The incidence rates for children aged 2-10 years ranged from 29.03 to 39.13%, and the incidence rate for children aged 11-14 years was 21.21%. Multivariate logistic regression analysis showed that age (OR = 0.9, 95%CI 0.82-0.99, P = 0.035) and female gender (OR = 2.42, 95%CI 1.21-4.83, P = 0.013) were independent risk factors for CPPV, and the incidence of CPPV decreased with age. The area under the ROC curve (AUC) for the training set of the constructed model was 0.632, and the AUC for the validation set was 0.708. The Hosmer-Lemeshow goodness-of-fit test indicated good model fit (training set P = 0.085, validation set P = 0.221), and the DCA curve suggested good clinical benefit.The nomogram model developed in this study demonstrates good clinical value. Children with unilateral inguinal hernia or hydrocele who are younger in age and female gender should undergo careful intraoperative exploration for the presence of CPPV. What is Known: • The probability of developing inguinal hernia in children with CPPV is 11%-25%, and redo surgery can increase surgical risks and financial burden. • The risk factors of unilateral inguinal hernia combined with CPPV are controversial. What is New: • Age and female gender are independent risk factors for CPPV. • A nomogram prediction model was constructed to provide a theoretical basis as well as an assessment tool for preoperative evaluation of whether children with unilateral indirect inguinal hernia are susceptible to CPPV.

BACKGROUND: Inguinal hernia repair (IHR) is a common pediatric operation performed via open or laparoscopic approaches. The objective of this survey study was to assess current approaches to IHR in a national sample of pediatric general surgeons.
METHODS: A REDCap survey was distributed to all pediatric general surgeons at 21 US institutions in 2023. Descriptive statistics were used to analyze responses.
RESULTS: The response rate was 70.0% (145/207) with median fellowship graduation year of 2011. Respondents reported they were primarily taught either an open (73.1%) or laparoscopic (6.9%) technique in fellowship, while 18.6% reported being taught both techniques equally. Overall, 60.7% of respondents reported currently performing both laparoscopic and open IHR, while 27.6% reported performing only open IHR and 11.7% reported performing only laparoscopic IHR. During unilateral open IHR, 75.8% of respondents check for and repair a contralateral inguinal hernia, most commonly by placing a laparoscope via the hernia sac (76.3%). Selective mesh use in adolescents was similar between laparoscopic and open repair approaches. For recurrent hernias, 37.2% of respondents indicated performing the approach that was not performed previously, while 38.6% and 22.8% indicated they routinely perform a laparoscopic or open approach, respectively, regardless of initial repair approach.
CONCLUSIONS: Over two thirds of surgeons reported incorporating laparoscopic IHR into their practice despite nearly three-quarters of respondents indicating they were primarily taught an open approach in training. Training in laparoscopic IHR has been increasing over time, and respondents reported a wide variety of laparoscopic and open repair techniques.
METHODS: IV.

BACKGROUND: The effect of pediatric inguinal hernia repair (IHR) on testicular vascularization remains unclear. Manipulating the spermatic cord during surgery may reduce blood flow due to edema and vasoconstriction. This can lead to testicular atrophy. The study aims to review current knowledge of testicular vascular impairment following IHR in children.
METHODS: A systematic literature search was conducted in PubMed/Medline, Embase, Cochrane Library, and Web of Science. Methodological quality was assessed using validated tools. Data were extracted, and a pooled data analysis was performed.
RESULTS: Ten studies were included in the systematic review. Six of these studies were eligible for meta-analysis. This revealed a significant decrease in testicular vascularization during the short-term follow-up (1 day-1 week) after IHR using the open surgical approach. This decrease was not present after laparoscopic intervention. There was no more increased resistance in the vessels at long-term follow-up (1 month-6 months), suggesting that the impaired vascularity is only temporary.
CONCLUSIONS: There seems to be a short-term transient vascular impairment of the testis after open IHR in children. This might be of clinical relevance to prefer the laparoscopic approach for IHR in children, even though the open approach is the gold standard, in contrast to adult IHR. The impact on testicular function and sperm quality later in life remains unclear. Comparative studies of both techniques are needed to determine if there is a significant difference in testicular vascularity. Long-term studies are necessary to assess the impact of transiently reduced vascularity on sperm quality and fertility later in life.

BACKGROUND: In pediatric patients, incarcerated inguinal hernias are often repaired on presentation. We hypothesize that in appropriate patients, repair may be safely deferred.
METHODS: The Nationwide Readmissions Database was used to identify pediatric patients (aged < 18 y) with incarcerated inguinal hernia from 2010 to 2014. Patients were stratified by management approach (Early Repair versus Deferral). Overall frequencies of these operative strategies were calculated. Propensity score matching was then performed to control for patient age, comorbidities, perinatal conditions, and congenital anomalies. Outcomes including complications, surgical procedures, and readmissions were compared. Outpatient surgeries were not assessed.
RESULTS: Among 6148 total patients with incarcerated inguinal hernia, the most common strategy was to perform Early Repair (88% versus 12% Deferral). Following propensity score matching, the cohort included 1288 patients (86% male, average age 1.7 ± 4.1 years). Deferral was associated with equivalent rates of readmission within one year (13% versus 15%, P = 0.143), but higher readmissions within the first 30 days (7% versus 3%, P = 0.002) than Early Repair. Deferral patients had lower rates of orchiectomy (2% versus 5%, P = 0.001), wound infections (< 2% versus 2%, P = 0.020), and other infections (7% versus 15%, P < 0.001). The frequency of other complications including bowel resection, oophorectomy, testicular atrophy, sepsis, and pneumonia were equivalent between groups. Three percent of Deferrals had a diagnosis of incarceration on readmission.
CONCLUSIONS: Deferral of incarcerated inguinal hernia repair at index admission is associated with higher rates of hospital readmissions within the first 30 days but equivalent readmission within the entire calendar year. These patients are at risk of repeat incarceration but have significantly lower rates of orchiectomy than their counterparts who undergo inguinal hernia repair at the index admission. We propose that prospective studies be performed to identify good candidates for Elective Deferral following manual reduction and overnight observation. Such studies must capture outpatient surgical outcomes.

OBJECTIVE: Introducing new surgical techniques in a developing country can be challenging. Inguinal hernias in children are a common surgical problem, and open repair is the standard surgical approach. Laparoscopic repair has gained popularity in developed countries because of similar results. This study aimed to determine the outcomes following the introduction of laparoscopic repairs in Guatemala.
METHODS: This retrospective analysis of prospectively collected data from all patients under 18 years who underwent laparoscopic repair at Corpus Christi Hospital in Patzun, Guatemala, from September 5th to September 8th, 2022.
RESULTS: A total of 14 patients were included in the study. A board-certified pediatric surgeon and a Guatemalan physician performed all cases. The mean patient age was 7.6 years; 7 boys and 7 girls. All patients were interviewed at 7 days, 30 days, and 6 months. There were no postoperative infections, pain requiring re-evaluation, gonadal atrophy, or hernia recurrence.
CONCLUSIONS: Under controlled circumstances with limited but proper equipment and disposables, laparoscopic inguinal hernia repairs can be introduced and performed in a developing country with a risk complication profile comparable to that in developed countries. This study provides promising evidence of laparoscopic repair feasibility and safety where surgical resources are limited.

BACKGROUND: Inguinal hernia (IH) repair is a common procedure in the daily practice of pediatric surgeons. In a developing country with limited facilities, it is important to be able to predict and diagnose contralateral patent processus vaginalis (CPPV) to avoid the risk and cost of further surgery.
OBJECTIVE: To assess the accuracy of ultrasound for the detection of CPPV, using laparoscopic evaluation as a confirmatory test. We also looked for various predictors of CPPV in our study population.
METHODS: 141 patients were included in this 2-year, cross-sectional prospective study. Inclusion criteria were unilateral inguinal hernia elective patients with no major comorbidities and aged between 2 months and 8 years. Each patient was assessed in outpatient clinics and then a pre-operative ultrasound was conducted. This was followed by laparoscopic evaluation during repair of the hernia.
RESULTS: Of the 141 patients included, 110 (78%) were males, 121 (85.9%) were born at full term, and 96 (68.1) had right-sided hernia. Mean age was 2.64 ± 1.9 years. Ultrasound was 85.7% sensitive in the detection of CPPV, 90.8% specific, and 90.1% accurate. In our analysis of patients younger than 1 year, right-sided hernia and defect size more than 10 mm were statistically significant predictors for a CPPV.
CONCLUSIONS: Ultrasound has a high accuracy profile and is a useful alternative in limited resource settings with restricted access to minimally invasive surgery for the prediction of CPPV. Patients younger than 1 year with a right-sided hernia or a manifested hernia defect larger than 10 mm are at a higher risk of having a CPPV.

OBJECTIVE: The advantage of using the single-port technique over the conventional two-port approach is uncertain. This study aimed to evaluate the outcomes of a single-port laparoscopic percutaneous extraperitoneal closure (SLPEC) using a modified needle grasper in children and compare the results to those of two-port laparoscopic percutaneous extraperitoneal closure (TLPEC).
METHODS: A retrospective cohort analysis of SLPEC and TLPEC surgery from February 2016 to June 2021 was conducted at our institution. Pediatric patients underwent SLPEC using the modified needle grasper to complete the high ligation of the hernia sac, while operations in the conventional two-port group only used regular laparoscopic instruments. A 1:1 propensity score matching (PSM) analysis was used to reduce selection bias.
RESULTS: Of 1320 patients, 1169 were included in the single-port/two-port crude evaluation, with 930 in the PSM cohort (465 patients/arm). Among 1:1 matched patients, the operation time for single-port patients vs. two-port patients were 11.28 ± 3.98 vs. 15.47 ± 4.54 min for unilateral repair and 16.86 ± 4.59 vs. 20.40 ± 4.29 min for bilateral repair (p < .05). Cosmetic results did not differ between the SLPEC and TLPEC groups (0% vs. 0.7%, p = 0.249). The recurrence rates were comparable between the two groups (0.6% vs. 1.1%, p = 0.725). Moreover, the differences in surgical site infection (SSI), testicular atrophy, open conversion and postoperative hydrocele occurrence were insignificant between the two groups.
CONCLUSIONS: In this cohort study, the modified needle grasper is a safe and feasible instrument for SLPEC, and SLPEC using the needle grasper has a shorter operation time than TLPEC.

UNASSIGNED: The number of times a research work gets cited by another article is one of the article-level metrics for assessing the quality of a research publication. Citation analysis by bibliometric review has been performed in several disciplines. The current study was aimed to systematically review the literature available on pediatric inguinal hernia since 1960 in terms of the 25 most cited articles in this field and analyze the bibliometric variables author and organizational collaborative patterns.
UNASSIGNED: Thomson Reuters Web of Science citation indexing database and research platform were used to retrieve the most cited articles in pediatric inguinal hernia (PIH) using appropriate search strings. The characteristics (name of authors, the total number of authors, the title of publication, journal of publication, year of publication, etc.) of the 25 top-cited articles were recorded. Specific bibliographical parameters were derived and analyzed. Visualization maps were generated using VOSviewer software.
UNASSIGNED: The analysis revealed that the Journal of Pediatric Surgery was leading the choice of journal for publication. While most of the publications originated from the United States of America, Schier was the most influential author. Five of the eight top-productive authors are also the most connected.
UNASSIGNED: Articles on laparoscopic repair in PIH have been heavily cited. Following the United States of America, Turkey stands out as the topmost productive country in PIH. The publications on PIH show that \"collaboration\" is the bridging force between productivity and influence on the academic community.

UNASSIGNED: Few studies have evaluated the efficacy of short-term medical missions. This study was aimed to evaluate complication rates and determine the effects of protocol changes in a pediatric inguinal hernia campaign in Equatorial Guinea and analyze post-operative follow-up capacity.
UNASSIGNED: In this prospective observational cohort study, we evaluated two patient cohorts (group A, 2017-2018; group B, 2019) treated during campaigns in Equatorial Guinea for congenital inguinal pathology (hernia, hydrocele, and cryptorchidism). Patients aged < 18 years treated in referral campaigns were included. Complications occurring up to 6 months post-operatively were evaluated. Two stages were defined: Stage 1, wherein, complication rate in group A was compared to that in a control group from a tertiary hospital in Spain (with a case-control ratio of 1:2, paired according to age, sex and diagnosis); stage 2, wherein, complication rates between groups A and B were compared. Group B received a single dose of prophylactic amoxicillin-clavulanic acid. Follow-up capacity was assessed through follow-up appointments.
UNASSIGNED: In stage 1, complication and surgical site infection (SSI) rates were 21.3% and 7.4% in group A (n = 94), and 5.8% (p < 0.001) and 0.5% (p = 0.012) in the control group, respectively. Group A had 20.2% loss-to-follow-up. In group B (n = 62), 6-month postoperative follow-up could not be assessed owing to restrictions due to the COVID-19 pandemic, so only early complications were considered in stage 2, were complication and surgical site infection rates were 18.1% and 7.4% in group A and 11.3% (p = 0.350) and 1.6% (p = 0.150) in group B.
UNASSIGNED: Our results showed higher than expected complication rates. Pre-operative prophylactic antibiotic could not show to reduce SSI. Further studies are needed to reduce complication rates in these campaigns. Patient loss-to-follow-up ratio warrants considering new strategies.

UNASSIGNED: A study was conducted to explore the characteristics of the videos on pediatric inguinal hernia repair on YouTube and compare the most popular videos (MPV) with the least popular ones in terms of educative value vis-a-vis their popularity.
UNASSIGNED: The term \"Pediatric inguinal hernia repair\" was searched for on YouTube on August 15, 2021, with the filter set to \"view rate.\" Pertinent data were collected from the 50 MPV and the 50 least popular videos (LPV) and then compared. The h-index and affiliation of the surgeon were obtained from the Scopus database, and their affiliation was further categorized as academic or nonacademic.
UNASSIGNED: One hundred and seventy-five videos were found with median views of MPV: LPV being 9270 (interquartile range [IQR] - 12099):127 (IQR - 194), respectively (P < 0.0001). Most of the videos in the MPV and LPV groups were uploaded from the United States of America (USA) (MPV - 17 and LPV - 13) and India (MPV - 15 and LPV - 15). The MPV were on YouTube for a median duration of 3.1 (IQR - 5.5) years as compared to 1.2 (IQR - 2.3) years for the LPV (P < 0.0001). Ninety-two surgeons were identified. The median h-index of the surgeons of MPV was 3 (IQR - 12) in comparison to 1 (IQR - 10) of LPV (P = 0.13). The ratio of academic versus nonacademic affiliation among MPV and LPV was almost equal in both the groups.
UNASSIGNED: On either end of the spectrum of popularity, the majority of the pediatric inguinal hernia videos on YouTube were surgical videos uploaded from the USA and India. The educative value of these videos was found to be low and widely dispersed. Surgeons from both academic and nonacademic affiliations had contributed similarly.
