Indocyanine Green Fluorescent Lymphography During Open Inguinal Hernia Repair: Relationship Between Lymphatic Vessel Injury and Postoperative Hydrocele.

BACKGROUND: This prospective case series analyzed patients who underwent indocyanine green (ICG) fluorescent lymphography during open inguinal hernia repair. The aim of this study was to investigate the association between ICG leakage and postoperative hydroceles in patients who underwent inguinal hernia repair. MATERIALS AND METHODS: Data were analyzed from 40 patients who underwent primary open hernia repair between October 2020 and June 2021 (44 cases in total). Hydroceles were categorized into two types: symptomatic and "ultrasonic" (detected only by ultrasound imaging). RESULTS: In the univariate analysis, hernia type (p = 0.044) and ICG leakage (p = 0.007) were independent risk factors for postoperative ultrasonic hydroceles. Additionally, mesh type (p = 0.043) and ICG leakage (p = 0.025) were independent risk factors for postoperative symptomatic hydroceles. In the multivariate analysis, ICG leakage (p = 0.034) was an independent risk factor for postoperative ultrasonic hydroceles. CONCLUSIONS: ICG leakage after inguinal hernia repair was independently associated with postoperative ultrasonic and symptomatic hydroceles. These findings suggest a relationship between lymphatic vessel injury and the incidence of postoperative hydroceles.

Patent processus vaginalis: role of ultrasound in pediatric population with unilateral inguinal hernia and other predictors.

INTRODUCTION: 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. OBJECTIVES: 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.

A Review of Scrotal Ultrasonography in Uyo, Nigeria.

BACKGROUND: Scrotal ultrasonography is a useful, sensitive, readily available and safe imaging modality in the investigation of scrotal pathologies, including those possibly contributory to male infertility. The aim of this study was to review the scrotal ultrasound scans (SUSS) done in the University of Uyo Teaching Hospital over a period of 18 months from July 2018 to December 2019. METHODOLOGY: This was a retrospective study of all the SUSS performed in the Department of Radiology of University of Uyo Teaching Hospital (UUTH) within an 18-month period. All subjects who presented for scrotal ultrasound with adequately filled request forms which included the biodata and clinical information were included in the study. RESULTS: A total of 79 scans were reviewed during the period. The age range of study patients was 4 - 78 years, with a mean of 41.2 ±15 years. The modal age group was 30-39 years, made up of 20 cases (25.6%). Primary and secondary infertility were the major indications for referrals, in 17 cases (21.8%) and 13 cases (16.7%) respectively. Following SUSS, the findings were normal in 11 patients (14.1%), while hydrocele, and varicocele accounted for 19 cases (24.3%) and 9 cases (11.5%) respectively. Microlitiasis was seen in 7 cases (9%) while a diagnosis of testicular tumor was made in 5 (6.4%) of cases. Three (3) of the 5 testicular tumors, were confirmed histologically. CONCLUSION: Infertility was the main indication for SUSS and hydrocele the commonest finding. Ultrasound is recommended as first line imaging modality in the investigation of scrotal lesions.

Radiological patterns of incidental epididymitis in mild-to-moderate COVID-19 patients revealed by colour Doppler ultrasound.

The testis is a potential target organ for SARS-CoV-2 infection. Our study intended to investigate any testicular involvement in mild-to-moderate COVID-19 men. We conduct a cross-sectional study in 18 to 55-year-old men hospitalised for confirmed COVID-19. A senior radiologist executed the ultrasound with multi-frequency linear probe in all participants, regardless of any scrotal complaints. Exclusion criteria involved any situation that could impair testicular function. Statistical analysis compared independent groups, classified by any pathological change. Categorical and numerical outcome hypotheses were tested by Fisher's Exact and Mann-Whitney tests, using the Excel for Mac, version 16.29 (p < .05). The sample size was 26 men (mean 33.7 ± 6.2 years; range: 21-42 years), all without scrotal complaints. No orchitis was seen. Eleven men (32.6 ± 5.8 years) had epididymitis (42.3%), bilateral in 19.2%. More than half of men with epididymitis displayed epididymal head augmentation > 1.2 cm (p = .002). Two distinct epididymitis' patterns were reported: (a) disseminated micro-abscesses (n = 6) and (b) inhomogeneous echogenicity with reactional hydrocele (n = 5). Both patterns revealed increased epididymal head, augmented Doppler flow and scrotal skin thickening. The use of colour Doppler ultrasound in mild-to-moderate COVID-19 men, even in the absence of testicular complaints, might be useful to diagnose epididymitis that could elicit fertility complications.

Trends in treatment outcomes of hydrocele in Japanese children: A single-institute experience.

OBJECTIVES: To investigate trends in treatment outcomes of surgical intervention versus observation for pediatric hydrocele. METHODS: This retrospective study included 175 patients diagnosed with hydrocele at our institution. Hydrocele was diagnosed based on medical history, physical examination and ultrasonography findings. The treatment for these patients was divided into two options: surgical intervention or careful follow up; the outcomes were investigated. RESULTS: The median age at diagnosis was 3 months, and a total of 11 patients (6%) were premature at birth. Hydrocele was diagnosed on the right side, the left side and bilaterally in 106 (61%), 46 (26%) and 23 (13%) patients, respectively. A total of 136 patients showed spontaneous improvement at the median 7 months after diagnosis, and 54 patients underwent surgical intervention. The rate of spontaneous resolution deceased with age, but spontaneous resolution was observed in patients aged >2 years. CONCLUSIONS: Our findings suggest that spontaneous resolution can be observed in patients aged >2 years, and surgical intervention can be carried out effectively and safely. Infant hydrocele should be followed up carefully for at least 1 year without surgical intervention since diagnosis. Investigation of the optimal timing of and appropriate reason for surgical intervention can lead to better management and outcomes in patients with hydrocele. Further research is warranted to support the current clinical practice.

Using Point-of-Care Ultrasound to Characterize Acute Inguinal Swelling of Young Children in the Pediatric Emergency Department.

Acute inguinal swelling in young children is frequently assumed to be an inguinal hernia, often prompting a bedside reduction attempt. We report 3 cases of inguinal swelling where the use of point-of-care ultrasound changed the patients' management by identifying an alternate diagnosis, thus avoiding unnecessary and painful procedures as well as their associated sedation risks.

Methylene blue dye for identification of processus vaginalis during hydrocele repair: experience in a teaching hospital.

BACKGROUND: The aim of this study is to investigate the use of methylene blue in perioperative identification of the patent processus vaginalis in a group of boys presenting with congenital or recurrent hydrocele where surgery was performed by junior surgeons in training. METHODS: We retrospectively reviewed the notes of 22 boys with hydrocele, of which two recurrences, who were operated via a standard inguinal approach, by trainees. Methylene blue 0.3-0.5 mL was injected into the hydrocele fluid through the scrotal wall. A processus vaginalis was identified as a blue line. RESULTS: Methylene blue injection clearly identified a patent processus vaginalis in 91% of patients. In 9% (N.=2), of which one recurrence, methylene blue injection demonstrated a hydrocele with an obliterated processus vaginalis. There were no intraoperative complications. No testicular atrophy was recorded. CONCLUSIONS: Injection of methylene blue into the hydrocele sac may be considered a useful aid for a clearer identification of a difficult patent processus vaginalis. In the present series, there were no complications, and thus we believe that this technique might be suitable and especially helpful, in cases of recurrent hydrocele, and for junior surgeons in training.

Diagnostic accuracy of preoperative ultrasonography in predicting contralateral inguinal hernia in children: a systematic review and meta-analysis.

OBJECTIVES: The incidence of children developing metachronous contralateral inguinal hernia (MCIH) is 7-15%. Contralateral groin exploration during unilateral hernia repair can prevent MCIH development and subsequent second surgery and anaesthesia. Preoperative ultrasonography is a less invasive strategy and potentially able to detect contralateral patent processus vaginalis (CPPV) prior to MCIH development. METHODS: We queried MEDLINE, Embase and Cochrane library to identify studies regarding children aged < 18 years diagnosed with unilateral inguinal hernia without clinical signs of contralateral hernia, who underwent preoperative ultrasonography of the contralateral groin. We assessed heterogeneity and used a random-effects model to obtain pooled estimates of sensitivity, specificity and area under the receiver operating characteristic curve (AUC). RESULTS: Fourteen studies (2120 patients) were included, seven (1013 patients) in the meta-analysis. In studies using surgical exploration as reference test (n = 4, 494 patients), pooled sensitivity and specificity were 93% and 88% respectively. In studies using contralateral exploration as reference test following positive and clinical follow-up after negative ultrasonographic test results (n = 3, 519 patients), pooled sensitivity was 86% and specificity 98%. The AUC (0.984) shows high diagnostic accuracy of preoperative ultrasonography for detecting CPPV, although diagnostic ultrasonographic criteria largely differ and large heterogeneity exists. Reported inguinal canal diameters in children with CPPV were 2.70 ± 1.17 mm, 6.8 ± 1.3 mm and 9.0 ± 1.9 mm. CONCLUSION: Diagnostic accuracy of preoperative ultrasonography to detect CPPV seems promising, though may result in an overestimation of MCIH prevalence, since CPPV does not invariably lead to MCIH. Unequivocal ultrasonographic criteria are mandatory for proper diagnosis of CPPV and subsequent prediction of MCIH. KEY POINTS: • Diagnostic accuracy of preoperative ultrasonography for detection of CPPV in children with unilateral inguinal hernia is high. • Preoperative ultrasonographic evaluation of the contralateral groin assumedly results in an overestimation of MCIH prevalence. • Unequivocal ultrasonographic criteria are mandatory for proper diagnosis of CPPV and risk factor identification is needed to predict whether CPPV develops into clinically apparent MCIH.

Well-differentiated papillary mesothelioma of tunica vaginalis testis of unknown malignant potential: Sonographic appearance.

Paratesticular mesothelioma is a rare differential diagnosis in the presence of scrotal hydrocele. A 17-year-old boy presented with a 3-year history of progressive hydrocele. Sonography revealed a large left paratesticular mass within the hydrocele. Serum tumor markers were negative. Left hydrocelectomy was performed and pathological analysis of the epididymal mass revealed a well-differentiated papillary mesothelioma. We discuss the sonographic and pathological findings of this rare neoplasm.

The challenging sonographic inguinal canal evaluation in neonates and children: an update of differential diagnoses.

Bulging of the inguinal region is a frequent complaint in the pediatric population and sonographic findings can be challenging for radiologists. In this review we update the sonographic findings of the most common disorders that affect the inguinal canal in neonates and children, with a focus on the processus vaginalis abnormalities such as congenital hydroceles, indirect inguinal hernias and cryptorchidism, illustrated with cases collected at a quaternary hospital during a 7-year period. We emphasize the importance of correctly classifying different types of congenital hydrocele and inguinal hernia to allow for early surgical intervention when necessary. We have systematically organized and illustrated all types of congenital hydrocele and inguinal hernias based on embryological, anatomical and pathophysiological findings to assist readers in the diagnosis of even complex cases of inguinal canal ultrasound evaluation in neonates and children. We also present rare diagnoses such as the abdominoscrotal hydrocele and the herniation of uterus and ovaries into the canal of Nuck.

Exploration Of The Contralateral Groin In Paediatric Inguinal Hernia Or Hydrocele Based On Ultrasound Findings - Is It Justified?

BACKGROUND: Routine exploration of contralateral side in cases of unilateral inguinal hernia or hydrocele is a highly debatable topic because of various reasons. The purpose of this study was to analyse whether the contralateral groin exploration in unilateral inguinal hernia/ hydrocele is justified or not, based on ultrasonographic measurements of the inguinal ring diameter. METHODS: This cross-sectional study was conducted at two naval hospitals, PNS Rahat and PNS Shifa in Karachi, Pakistan, from June 2007 to Aug 2012. Children presenting with unilateral inguinal hernia or hydrocele were included in the study. Ultrasound examination of the contralateral, apparently normal, groin was carried out using a high-resolution 7.5-11 MHz linear array with the patients in supine position. Surgical exploration of the contralateral groin was carried out in those children in whom the diameter of the inguinal canal at the internal ring was 4.5 mm or greater. All those children in whom the contralateral exploration was not done were followed up to 2 years. RESULTS: A total of 287 patients completed the study, including 264 (92%) boys and 23 (8%) girls. In 242 (84%) cases, the mean diameter of internal ring on contralateral (clinically uninvolved) side was 3.5±0.4 mm, considered negative. Out of these 13 (5.4%) cases, however, proved to be false negative after a follow up of two year. There were 45 (16%) cases that underwent contralateral exploration on basis on positive ultrasound findings; 25 (55.6%) were hernias and 14 (31.1%) were hydroceles. In the remaining 6 (13.3%) cases surgical exploration failed to demonstrate hernia or PPV. CONCLUSIONS: Contralateral exploration in children with unilateral inguinal hernia or hydrocele, based on ultrasonographic findings, is not only cost effective but can also prevent unnecessary routine contralateral explorations and complications related to inguinal hernias.

Imaging of mesothelioma of tunica vaginalis testis.

OBJECTIVES: To describe the imaging findings in a series of patients with mesothelioma of the tunica vaginalis testis. METHODS: We reviewed clinical data, imaging findings and follow-up information in a series of 10 pathology-proven cases of mesothelioma (all had US; 2 had MR) of the tunica vaginalis. RESULTS: A variety of patterns could be observed, the most common (5/10) being a hydrocele with parietal, solid and hypervascular vegetations; one patient had a septated hydrocele with hypervascular walls; one had multiple, solid nodules surrounded by a small, physiological quantity of fluid; one a cystic lesion with thick walls and vegetations compressing the testis; two had a solid paratesticular mass. MR showed multiple small nodules on the surface of the tunica vaginalis in one case and diffuse thickening and vegetations in the other one; lesions had low signal intensity on T2-w images and were hypervascular after contrast injection. CONCLUSIONS: A preoperative diagnosis of mesotheliomas presenting as solid paratesticular masses seems very difficult with imaging. On the contrary, the diagnosis must be considered in patients in whom a hydrocele with parietal vegetations is detected, especially if these show high vascularity. KEY POINTS: Mesotheliomas of the tunica vaginalis are rare, often challenging to diagnose preoperatively. Most common finding is a complex hydrocele with hypervascular parietal vegetations. Septated hydrocele, nodules without hydrocele, a thick-walled paratesticular cyst are less common. Preoperative diagnosis may allow aggressive surgical approach and, possibly, a better prognosis.

Nonobliteration of the Processus Vaginalis: Sonography of Related Abnormalities in Children.

The objective of this pictorial essay is to systematically classify processus vaginalis-related disorders in the light of embryology and present illustrative sonograms with corresponding diagrams. Failure of the processus vaginalis to obliterate during gestation results in a wide spectrum of anomalies, including communicating and noncommunicating hydroceles and inguinal and inguinoscrotal hernias, along with other related disorders of the genital system. There are varying classifications in the literature regarding the aforementioned entities. Proper and timely diagnosis of these entities is essential, given the differences in treatment. Although physical examination can narrow the differential diagnosis, sonography plays an essential role in establishing the diagnosis.

Epididymal anomalies in boys with undescended testis or hydrocele: Significance of testicular location.

BACKGROUND: Epididymal anomalies and patent processus vaginalis are frequently found in boys with cryptorchidism or hydrocele. We conducted this study to evaluate the association between epididymal anomalies and testicular location or patent processus vaginalis in boys with undescended testis or hydrocele. METHODS: Children undergoing surgery with undescended testis (group A, 136 boys and 162 testes) or communicating hydrocele (group B, 93 boys and 96 testes) were included. Testicular locations and epididymal anomalies were investigated prospectively. An anomalous epididymis was defined as anomalies of epididymal fusion that consisted of loss of continuity between the testis, the epididymis, and the long looping epididymis. The epididymis was considered normal when a normal, firm attachment between the testis, the caput, and the cauda epididymis was present. RESULTS: The mean ages of groups A and B were 24.6 ± 19.7 (range, 8-52 months) and 31.4 ± 20.6 months (range, 10-59 months). The incidence of epididymal anomalies was significantly higher in group A than that in group B (65.4 % vs. 13.5 %, P < .001). The incidence of epididymal anomalies in boys with undescended testis was significantly different according to testis location. Epididymal anomalies were observed in 100 %, 91.4 %, and 39.3 % of cases when the testis was located in the abdomen, inguinal canal, and distal to the external inguinal ring, respectively (P < 0.001). CONCLUSION: We conclude that epididymal anomalies were more frequent in boys with undescended testis than in boys with hydrocele, and that these anomalies were more frequent when undescended testis was at a higher level. These results suggest that testicular location is associated with epididymal anomalies rather than patent processus vaginalis.

Sonography of the scrotum: from appendages to scrotolithiasis.

In this pictorial essay, we review and discuss the varying morphologic characteristics of scrotal appendages and calculi. Characteristic sonograms obtained from patients with coexisting hydrocele are presented, and recent literature is included. Hydrocele greatly facilitates the imaging of these intrascrotal structures, as it acts as a "water path". On the one hand, torsion of a scrotal appendage should always be included in the differential diagnosis of acute scrotum, especially in children. On the other hand, scrotolithiasis may occasionally cause mild discomfort. As a consequence, and given the widespread use of sonography for the evaluation of both acute and chronic conditions of the scrotum, radiologists should be familiar with these entities.

Scrotal swelling in the neonate.

Discovery of scrotal swelling in a neonate can be a source of anxiety for parents, clinicians, and sonologists alike. This pictorial essay provides a focused review of commonly encountered scrotal masses and mimics specific to the neonatal setting. Although malignancy is a concern, it is very uncommon, as most neonatal scrotal masses are benign. Key discriminating features and management options are highlighted to improve the radiologist's ability to diagnose neonatal scrotal conditions and guide treatment decisions. Neonatal scrotal processes ranging from common to uncommon will be discussed.

Scrotal calculi in clinical practice and their role in scrotal pain: A prospective study.

PURPOSE: Scrotal calculi are rare, and their clinical significance is uncertain. Scrotal pain is a frequent, hard-to-manage problem in urology clinics. Our purpose in this study was to determine the relationship between the presence of scrotal calculi and scrotal pain in a prospective manner. METHODS: Sonography and color Doppler ultrasound of the scrotum were performed in 758 consecutive patients referred with scrotal pain. The pain was rated by using an 11-point numeric rating scale; scores were compared among patients with scrotal calculi with and without additional scrotal pathology. RESULTS: Scrotal calculi were detected in 73 of the 758 patients (9.6%). Scrotal pain (n = 50 [61%]) and a palpable mass in the scrotum (n = 25 [30.5%]) were the most common complaints in patients with scrotal calculi. Hydrocele (n = 17 [29.8%]) and varicocele (n = 15 [26.3%]) were the most commonly associated abnormalities; there was a statistically significant association between the presence of scrotal calculi and hydrocele (p < 0.01). Scrotal pain was present in 61 (83.5%) patients with scrotal calculi, and this association was significant (p < 0.001). The presence of scrotal pain and the correlation between location of calculi and pain in patients without additional scrotal abnormalities were also significant (p = 0.04 and p < 0.004, respectively). CONCLUSIONS: The prevalence of scrotal calculi was 9.6%, and hydrocele was found to be associated with scrotal calculi. We also found a significant relationship between the presence of calculi and scrotal pain. Because the etiology of scrotal pain is essential for appropriate treatment, scrotal calculi should be kept in mind when making a differential diagnosis of scrotal pain. © 2014 Wiley Periodicals, Inc.

Minimally access versus conventional hydrocelectomy: a randomized trial.

OBJECTIVE: To compare our previously published new minimally access hydrocelectomy versus Jaboulay's procedure regarding operative outcome and patient's satisfaction. MATERIALS AND METHODS: A total of 124 adult patients were divided into two groups: A and B. Group A patients were subjected to conventional surgical hydrocelectomy (Jaboulay's procedure) and group B patients were subjected to the new minimal access hydrocelectomy. The primary endpoint of the study was recurrence defined as a clinically detectable characteristic swelling in the scrotum and diagnosed by the two surgeons and confirmed by ultrasound imaging study. The secondary endpoints were postoperative hematoma, wound sepsis and persistent edema and hardening. RESULTS: The mean operative time in group B was 15.1 ± 4.24 minutes and in group A was 32.5 ± 4.76 minutes (P ≤ 0.02). The mean time to return to work was 8.5 ± 2.1 (7-10) days in group B while in group A was 12.5 ± 3.53 (10-15) days (P=0.0001). The overall complication rate in group B was 12.88% and in group A was 37%. The parameters of the study were postoperative hematoma, degree of scrotal edema, wound infection, patients' satisfaction and recurrence. CONCLUSION: Hydrocelectomy is considered the gold standard technique for the treatment of hydrocele and the minimally access maneuvers provide the best operative outcomes regarding scrotal edema and hardening and patient's satisfaction when compared to conventional eversion-excision hydrocelectomies.
