Conventional herniorrhaphy followed by laparoscopic appendectomy for a variant of Amyand's hernia: a case report.

BACKGROUND: Amyand's hernia (AH) is an appendix (with or without acute inflammation) trapped within an inguinal hernia. Most AH with acute appendicitis had a preexisting appendix within the hernia sac. We herein report a variant of AH that has never been described before. An inflamed appendix that was managed conservatively was found to have migrated and trapped in the sac of a previously unrecognized right inguinal hernia 6 weeks after the index admission, resulting in a secondary Amyand's hernia. CASE PRESENTATION: A 25-year-old healthy Taiwanese woman had persistent right lower abdominal pain for 1 week and was diagnosed with perforated appendicitis with a localized abscess by abdominal computed tomography (CT). No inguinal hernia was noted at that time. Although the inflamed appendix along with the abscess was deeply surrounded by bowel loops so that percutaneous drainage was not feasible, it was treated successfully with antibiotics. However, she was rehospitalized 6 weeks later for having a painful right inguinal bulging mass for a week. Abdominal CT revealed an inflamed appendix with abscess formation in an indirect inguinal hernia raising the question of a Amyand's hernia with a perforated appendicitis. Via a typical inguinal herniorrhaphy incision, surgical exploration confirmed the diagnosis, and it was managed by opening the hernial sac to drain the abscess and reducing the appendix into the peritoneal cavity, followed by conventional tissue-based herniorrhaphy and a laparoscopic appendectomy. She was then discharged uneventfully and remained well for 11 months. CONCLUSIONS: Unlike the traditional definition of Amyand's hernia, where the appendix is initially in the hernia sac, the current case demonstrated that Amyand's hernia could be a type of delayed presentation following initial medical treatment of acute appendicitis. However, it can still be managed successfully by a conventional tissue-based herniorrhaphy followed by laparoscopic appendectomy.

Inguinal endometriosis: a case series and review of the literature.

BACKGROUND: Inguinal endometriosis is one of the most common forms of endometriosis. The present study introduces 8 cases of inguinal endometriosis and discusses probable theories of inguinal endometriosis by reviewing the literature. CASE PRESENTATION: 8 Iranian cases of inguinal endometriosis with a mean age of 36 years were presented. Catamenial groin pain and swelling were the most common complications. Also, patients usually had accompanying symptoms such as pelvic pain and dysmenorrhea. One-half of patients had a history of previous abdominal surgery. Ultrasound was diagnostic in 4 patients (50%), and magnetic resonance imaging was used in two patients (25%). Among 6 patients who underwent hormonal therapy, 4 experienced an endometriosis size increase. Inguinal endometriosis was right-sided in 87.5% of patients, and among 4 patients who underwent surgery, 75% had proximal site involvement of the round ligament. CONCLUSION: According to the rarity of inguinal endometriosis, it is more likely to be a misdiagnosis with other inguinal disorders such as inguinal hernia. Inguinal endometriosis should be considered in patients who undergo inguinal herniorrhaphy, with suspected findings such as thickening of the hernia sac wall, bloody fluid inside the sac, or thickening of the extraperitoneal round ligament during the surgery.

Effectiveness of preoperative ultrasonography in predicting metachronous contralateral inguinal hernia in children: a single-arm prospective study using a historical control for comparison.

PURPOSE: To analyze the value of ultrasonography in predicting metachronous contralateral inguinal hernia (MCIH) and diagnosing contralateral persistent processus vaginalis (CPPV) in children with unilateral inguinal hernia, a prospective study was conducted. METHODS: All participants underwent a preoperative ultrasound on the contralateral groin. Patients in group A1 received operating procedure according to ultrasound results (patients with negative contralateral US results received hernia repair on the affected side), and patients in group A2 received operation according to laparoscopic results (patients received hernia repair and CPPV ligation). All patients were followed up 2 years and compared to a historical control (group B) who underwent open hernia repair only on the affected side regardless of contralateral US results. RESULTS: In groups A1 and A2, laparoscopic exploration revealed the presence of a CPPV in 490 cases. Ultrasound was found to be accurate in 104 out of the 490 cases with four false-positive and 386 false-negative results. This yielded an accuracy of 59.3%, a sensitivity of 21.2%, and a specificity of 99.2%. 10 patients in group A1, and 74 patients in group B developed MCIH. The accuracy, sensitivity, and specificity of the value of ultrasonography in predicting MCIH were 89.3%, 52.4%, and 92.5%, respectively. CONCLUSIONS: Preoperative ultrasonography of the contralateral groin is currently unable to accurately detect CPPV, but it appears to be a promising method in predicting MCIH by using rigorous diagnosing criteria.

Fetal Inguinal Hernia: Case Report and Review of the Literature.

Fetal inguinal hernia (FIH) is a rare event and only few cases were published in the medical literature. In the present study, we aimed to characterize the sonographic features, clinical presentation, management, outcomes, and differential diagnoses of FIH. Accordingly, we reviewed all 17 cases of FIH published in the medical literature, including one new case evaluated by our group. All 17 cases (100%) were male, and FIH is presented as a scrotal mass with a mean diameter of 38 ± 9.5 mm. The right side was dominant (62%). Peristalsis was reported in 80% of the cases, and blood flow was reported in two-thirds. Most cases were diagnosed in the third trimester (88%) at a mean gestational age (GA) of 33.1 ± 5.2 weeks. 60% of the cases had isolated FIH, and 40% had another sonographic or genetic abnormality. Three cases (18%) were syndromic with multiple malformations: trisomy 18, skeletal anomalies due to Jarcho-Levin syndrome, and undefined multiple joint contractures. Two cases (12%) had copathologies in the gastrointestinal tract: one had an echogenic bowel due to homozygosity for cystic fibrosis, and the other had low anorectal malformation. Bowel loop dilatation was observed prenatally in both cases and in another one isolated case (18%). GA at delivery was 38 ± 1.8 weeks, and the median time between diagnosis and delivery was 3 weeks. All three cases of neonatal death occurred in syndromic fetuses. All patients with nonsyndromic inguinal hernias underwent definitive surgical repair at a median of 13 days postpartum. No signs of strangulation and only one case of edematous bowel without necrosis have been reported. In conclusion, FIH should be suspected in male fetuses when an intrascrotal mass with peristalsis is diagnosed during the third trimester. Close follow-up until term in the absence of signs of bowel obstruction is reasonable, and in isolated FIH, the prognosis is favorable.

Canal of nuck hernia with uterus and ovary presenting as inguinal swelling in a female infant.

Canal of nuck hernia is rarely reported in pediatric population. We report one such case of a canal of nuck hernia in a 2-month-old girl containing uterus, ovary and small bowel diagnosed on ultrasonography, and which was later confirmed and treated surgically.

Incarcerated hernia with ileal perforation in an extreme preterm infant.

We describe a case of a premature 24 weeks gestation infant who presented with clinical lability and abdominal distention with initial concerns of necrotising enterocolitis. On further examination, a right inguinal hernia was noted and serial abdominal X-rays showed bowel loop dilatation with intramural air and no perforation. However, the hernia was recurrent and later found to be not reducible. He underwent right groin exploration. Intraoperatively, distal ileal perforation was noted and he was found to have an additional five sites of perforation. He had a stoma sited at the left iliac fossa as well as primary anastomosis at the site of the second to fifth perforations. He had a stormy postoperative period but is currently doing well. Although obstructed hernias are rare in the initial course of an extreme preterm infant, it should not be missed as a cause of intestinal obstruction and early surgical opinion should be sought.

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.

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.

Management of groin hernias detected by ultrasound: a comprehensive study.

INTRODUCTION: It remains unclear whether ultrasound-detected hernias (UDH) are the sole cause of pain in patients with groin pain, and clinical examination plays a complementary role. The aim of our study is to describe the evolution of patients with ultrasound detected hernias in terms of development of groin hernia detected by physical examination, pain resolution, and alternative diagnosis. METHODS: An observational, descriptive, longitudinal study of a prospective case series including patients with UDH with groin pain. Follow-up evaluation included the following: follow-up time, side of pain, its evolution, time to resolution, clinical hernia (CH) development, need for surgical resolution, and the presence of postoperative pain and alternative diagnosis. RESULTS: A total of 98 patients with complete follow-up for groin pain and UDH were included. Seven patients (7.1%) developed CH, with a median time to conversion of 8 months. Four of them (4.1% of the total and 57.1% of the ones who developed CH) ended up having surgery. Fifty-three patients (54.1%) resolved their pain in a median time to resolution of 2 months, and 75.5% of them did so spontaneously. The majority of patients with persistent pain (73.3%) were able to lead a normal life and only reported pain with movement. More than half of the patients (53.3%) reached a specific diagnosis. Among those patients who did not develop CH, 39.6% reached an alternative diagnosis, the majority being musculoskeletal pathologies. CONCLUSION: Watchful waiting and a thorough search for other alternative causes of groin pain in UDH and clinically occult hernia would be a reasonable option.

Where is the testis? The role of ultrasound and diagnostic laparoscopy for Crossed Testicular Ectopia (CTE): Case report and review of literature.

Crossed Testicular Ectopia (CTE) or transverse testicular ectopia is an anecdotic urogenital anomaly in which both testes are located on the same side, generally associated with a patent processus vaginalis (PPV). The condition can be detected by ultrasound. Nevertheless, the diagnosis is often missed preoperatively and CTE is recognized intraoperatively. Controversy exists regarding management and the role of diagnostic laparoscopy. The surgical technique depends on the anatomy of vas, vessels and testis found on surgical exploration. Diagnostic laparoscopy can be useful to rule out a vanishing testis and detect Müllerian remnants. We present the case of 8-months infant with no palpable testis on the right side and no signs of inguinal hernia, reporting the management and reviewing the scarce existing literature in this regarding. KEY WORDS: Crossed Testicular Ectopia, Laparoscopy, Ectopia, Testis, Transverse Testicular Ectopia, Urogenital Abnormalities.

Synchronic development of hydrocele and groin hernia during pregnancy: a case report.

INTRODUCTION: Hydroceles of the canal of Nuck are rare, and have not been described in relation to pregnancy. CASE PRESENTATION: A 34-year-old Caucasian female patient had bilateral groin swelling debuted during her pregnancy. A preoperative magnetic resonance imaging scan found bilateral hydroceles of the canal of Nuck. Operative findings and histological examinations revealed a left-sided inguinal hernia and a right-sided hydrocele. The patient was discharged well and without signs of postoperative complications or hernia recurrence. DISCUSSION: In this case, a hydrocele and a hernia sac were morphologically identical in terms of preoperative appearance and development. Given the morphological correlation, it was surprising to find different operative findings confirmed by the histopathological examination. CONCLUSION: This is the first ever report of the synchronic development of two morphologically identical cystic processes, with one being a hydrocele and the other a hernia sac. In addition, the hydrocele developed during pregnancy, making this case even more unique.

Neither inguinoscrotal hernia nor hydrocele misunderstood giant testicular neoplasm. Case report and literature review.

AIM: This case experience aims to question the current know-how when a masked testicle malignancy occurs, in order to achieve the correct clinical framework and avoid mistakes during surgical procedures. in the evaluation MATERIALS AND METHODS: A 36-year-old male patient was admitted with an incorrect diagnosis of left-sided incarcerated inguinoscrotal hernia, and then discovered a seminomatous testicular neoplasm matched with a hypertensive ipsilateral hydrocele. Therefore, we performed a radical epididymo-orchiectomy and referred the patient to the oncologist for adjuvant chemotherapy after discharge. RESULTS: The surgery was perceived by the patient as the best possible treatment because the symptoms were relieved. DISCUSSION: A 36-year-old male patient was admitted to our surgical department due to an incorrect diagnosis of leftsided incarcerated inguinoscrotal hernia, consequently to a misguided scrotal ultrasound-doppler exam. During the urgent surgical operation, we realized that we were dealing with an enormous 17x10x9 cm seminomatous testicular neoplasm matched with a hypertensive ipsilateral hydrocele. Therefore, we performed a radical epididymo-orchiectomy and referred the patient to the oncologist for adjuvant chemotherapy after discharge. CONCLUSION: This case report points out that there may be a poor correlation between clinical findings and pathophysiologic processes affecting scrotal structures. Additional radiological investigations, such as CT scan, could clarify and confirm the clinical scenario, improving the preoperative planning and surgical outcomes. KEY WORDS: Inguinal Hernia, Seminoma, Testicular Neoplasm.

The emerging role of MRI neurography in the diagnosis of chronic inguinal pain.

INTRODUCTION: Chronic pain is a frequent and notable complication after inguinal hernia repair, it has been extensively studied, but its management and diagnosis are still difficult. The cause of chronic pain following inguinal hernia surgery is usually multifactorial. This case series highlights the utility of MRI neurography (MRN) in evaluating the damage to inguinal nerves after a hernia repair, with surgical confirmation of the preoperative imaging findings. MATERIALS AND METHODS: A retrospective review was performed on patients who underwent inguinal mesh removal and triple denervation of the groin. Inclusion criteria included MRI neurography. All patients underwent surgical exploration of the inguinal canal for partial or complete mesh removal and triple denervation of the groin by the same senior surgeon. RESULTS: A total of nine patients who underwent triple denervation were included in this case series. MRN was then performed on 100% of patients. The postoperative mean VAS score adjusted for all patients was 1.6 (SD p), resulting in a 7.5 score difference compared to the preoperative VAS score (p). Since chronic groin pain can be a severely debilitating condition, diagnosis, and treatment become imperative. CONCLUSION: MRN can detect direct and indirect signs of neuropathy even in the absence of a detectable compressive cause aids in management and diagnosis by finding the precise site of injury, and grading nerve injury to aid pre-operative assessment for the nerve surgeon. Thus, it is a valuable diagnostic tool to help with the diagnosis of nerve injuries in the setting of post-inguinal hernia groin pain.

Diagnostic performance of CT with Valsalva maneuver for the diagnosis and characterization of inguinal hernias.

PURPOSE: Inguinal hernias are mainly diagnosed clinically, but imaging can aid in equivocal cases or for treatment planning. The purpose of this study was to evaluate the diagnostic performance of CT with Valsalva maneuver for the diagnosis and characterization of inguinal hernias. METHODS: This single-center retrospective study reviewed all consecutive Valsalva-CT studies between 2018 and 2019. A composite clinical reference standard including surgery was used. Three blinded, independent readers (readers 1-3) reviewed the CT images and scored the presence and type of inguinal hernia. A fourth reader measured hernia size. Interreader agreement was quantified with Krippendorff's α coefficients. Sensitivity, specificity, and accuracy of Valsalva-CT for the detection of inguinal hernias was computed for each reader. RESULTS: The final study population included 351 patients (99 women) with median age 52.2 years (interquartile range (IQR), 47.2, 68.9). A total of 381 inguinal hernias were present in 221 patients. Sensitivity, specificity, and accuracy were 85.8%, 98.1%, and 91.5% for reader 1, 72.7%, 92.5%, and 81.8% for reader 2, and 68.2%, 96.3%, and 81.1% for reader 3. Hernia neck size was significantly larger in cases correctly detected by all three readers (19.0 mm, IQR 13, 25), compared to those missed by all readers (7.0 mm, IQR, 5, 9; p < 0.001). Interreader agreement was substantial (α = 0.723) for the diagnosis of hernia and moderate (α = 0.522) for the type of hernia. CONCLUSION: Valsalva-CT shows very high specificity and high accuracy for the diagnosis of inguinal hernia. Sensitivity is only moderate which is associated with missed smaller hernias.

Obstructed inguinal hernia containing ovary with an ovarian cyst: a case report.

A 27-year-old married woman came to the emergency room (ER) with the chief complaint of severe pain in the abdomen for 3 days, which was more pronounced in the right iliac fossa, along with the complaint of multiple episodes of vomiting for the last 6 hours. She also gave a history of swelling in the right inguinal region for last 9 months with the complaint of mild on and off pain in the swelling. On physical examination, diagnosis of obstructed inguinal hernia was made. Ultrasonography (USG) of abdomen was of no use, as it only commented on hernial defect and not on the contents of the hernial sac. An emergency surgery was planned; marsupialisation of ovarian cyst, repositioning of fallopian tube along with ovary and herniorrhaphy was performed without any difficulty.
