PURPOSE: We evaluated the contralateral patent processus vaginalis(CPPV) by transinguinal laparoscopy in boys with unilateral inguinal hernia, to determine its incidence and the association with various clinical parameters. We also investigated the factors responsible for the development of a metachronous inguinal hernia. MATERIALS AND METHODS: One hundred sixty seven boys with unilateral inguinal hernia were analyzed. The morphology of the ring was classified into four patterns(type 1, 2a, 2b, and 3). We analyzed the morphology of the internal ring and the variables related to a CPPV by age, laterality and the size of the ipsilateral and/or bilateral hernia sac. RESULTS: The incidence of a CPPV was 33.9%. The positive predictive value was 94.9%(56/59). There was no statistical difference in the incidence of a CPPV by laterality. The incidence of a CPPV was significantly higher in the group with a larger size(>or=1cm) compared to the smaller abnormalities(<1cm). The incidence of the type 3 pattern was higher than the type 2b pattern in the group with larger abnormalities. With increasing age, type 1 and 2a patterns increased in frequency, but type 2b decreased and the type 3 pattern was stable. The size of the contralateral hernia sac was significantly larger with the type 3 pattern than the type 2b. CONCLUSIONS: The results of our study showed that the size of the hernia sac and patient age were related to the presence of a CPPV. A type 3 pattern was associated with a more primitive morphology, a wider hernia sac and no change in the incidence with advancing age. Therefore, the findings of this study suggest that a metachronous inguinal hernia develops more commonly in patients with a type 3 pattern internal ring.

Torsion of a hernia sac is an extremely rare condition that presents as acute scrotum in children. We report a case of a 6-year-old boy who presented with an acute scrotum and was found during surgical exploration to have torsion of an indirect hernia sac associated with hydrocele. Upon scrotal exploration, deterioration of the scrotum due to inflammatory changes was found. A necrotic cyst was recognized within a communicating hydrocele of the scrotum and was twisted at an angle of about 360degrees. All urologists should be aware of this special condition in the differential diagnosis of acute scrotum.

Between March 1999 and January 2000, 82 boys with the diagnosis of inguinal hernias (12 bilateral and 70 unilateral hernias), underwent Ultrasound (US) examination of both sides of the groin, a total of 164 inguinal imaging prior to surgery. The patients ages ranged from 3 days to 12 years with a mean of 32.6 months. Ninty four examinations were on the clinically symptomatic side and 70 were on the asymptomatic side. The US criteria for the diagnosis of an inguinal hernia were as follows: 1) visceral hernia, the presence of bowel loops, or omentum in the inguinal canal, 2) communicating hydrocele, the presence of fluid in the processus vaginalis, 3) widening of patent processus vaginalis at the level of nternal inguinal ring. The width of patent processus vaginalis at the level of internal inguinal ring over 4 mm is onsidered an occult hernia. Among the 94 symptomatic groins, US findings showed 31 (33 %) visceral hernias, 18 (19 %) communicating hydroceles, and 38 (41 %) widening of the internal inguinal ring, and 7 (7 %) groins without abnormalities. In 70 asymptomatic groins, there were 4 (6 %) visceral hernias, 5 (7 %) communicating hydroceles, 11 (16 %) widening of the internal inguinal ring, and 50 (70 %) groins without abnormalities. Among the 70 asymptomatic groins there were US abnormalities in 20 (28 %). One hundred and seven groins with positive US findings were surgically explored. Among 107 operated sites, the operative findings were compatible with the US diagnosis in 104, a sensitivity for US of 97.2 %. In patients with US findings of widening of internal inguinal ring (>4 mm), there was patent processus vaginalis in 36 out of 38 symptomatic groins and 10 of 11 asymptomatic groins. The sensitivity of US to the operative findings in widening of internal inguinal ring was 93.8 %. For visceral hernia and communicating hydrocele, the sensitivity of positive US findings was 100 %. Ultrasonography for inguinal hernias appears to be a rapid, reliable, and noninvasive screening diagnostic tool with high positive specificity. Therefore, we recommend the use of US as a routine diagnostic tool in pediatric patients with inguinal hernias and hydroceles.

A palpable mass in lower abdomen of a neonate or an infant can be most frequently considered as an inguinal hernia, whereas pediatric adnexal torsion is less commonly considered in differential diagnosis but can occur. Pediatric adnexal torsion may be difficult to diagnose clinically but the immediate diagnosis may lead to more frequent salvage of affected adnexa. Sonography is the preferred imaging study. It usually confirms a pelvic mass but may not establish the diagnosis. The correct diagnosis of adnexal torsion is often made at exploration. Therapy for adnexal torsion remains controversial. While extirpation has been the standard of treatment in the past, there are current proponents of conservative therapy with adnexal preservation.

Herniation of the appendix into an inguinal canal is known as an Amyand hernia. Due to its nonspecific symptoms, clinical diagnosis is extremely difficult, and an accurate preoperative diagnosis of Amyand hernia with ultrasound (US) and CT is rarely reported. Herein, we reported a typical case of Amyand hernia in a 74-year-old male in which the correct diagnosis was made using inguinal US and contrast-enhanced abdominopelvic CT. US and CT findings of Amyand hernia showed a target-like tubular structure within the inguinal canal.

An indirect inguinal hernia containing the fallopian tube alone is extremely rare in reproductive-aged women without any genital tract anomalies. Despite this rarity, early diagnosis and adequate management is important to prevent strangulation and recurrence. We present a case of an indirect inguinal hernia containing only the fallopian tube in the hernia sac, which was successfully reduced by using a laparoscopic total extraperitoneal approach and repaired with a polypropylene mesh.

The purpose of this retrospective study was to evaluate the effects of diagnostic sonography in pediatric patients with inguinal hernias. The patients were classified into two groups. Group A included the patients who had been operated upon for inguinal hernia in 1980's, when diagnostic sonography was not available. Group B included the patients, operated upon for inguinal hernia from 2001 to 2002, when inguinal sonography was employed to detect potential bilateral hernias. The age distribution, sex ratio, laterality, bilaterality, and concomitant symptoms were compared between group A and group B. There were 296 cases in group A and 377 cases in group B. The prevalent age group was from 1 to 5 years. There was no difference in age group distribution between both groups. The male to female ratio was 5.3:1 in group A and 3.5:1 in group B. The ratio of unilateral to bilateral hernia was 5:1 in group A and 3:1 in group B. In cases with a unilateral hernia, the ratio of right to left was 1.5:1 in group A and 1.8:1 in group B. In cases with bilateral hernia, the simultaneous bilateral hernia was 33 cases (67.4 %) in group A and 75 cases (80.6 %) in group B. The sequential bilateral hernia was 16 cases (32.7 %) in group A and 18 cases (19.4 %) in group B. Although the ratio of bilateral hernia was increased in group B, the portion of the sequential bilateral hernia was significantly decreased in group B. In conclusion, there were no differences in the age distribution and the laterality between group A and B. The ratio of female patients and the incidence of bilateral hernia were increased in group B even though the portion of the sequential bilateral hernia was decreased. This result shows that the preoperative inguinal sonography in unilateral hernia with potential bilateral hernia is useful in early detection of the sequential contralateral hernia.

A lipomatous lesion of the cord is an accidentally encountered structure during the operative repair of inguinal hernia. This lesion has been reported as a lipoma of the cord in adults. However, there is only a limited number of reports in the pediatric age group. To evaluate the prevalence of this lesion in children and in order to review the surgical significancies, 600 hernia operations in 411 children during a period of 4 years from January, 2000 to December, 2003 in the Division of Pediatric Surgery, Department of Surgery, the Catholic University of Korea, were included in this study. There was a total of 31 (5.2%) lipomatous lesions in 25 (6.1%) cases; 3 cases in infants, 17 between 1 to 4 years, and 5 above 5 years of age. Male was more prevalent (male to female ratio 14:11). The laterality of clinical hernia with the lesions was 10 in the right, 13 in the left and 2 in both sides. The patients with ipsilateral lesions to the hernia were 14, contralateral in 5 and bilateral in 6 cases. Excluding 1 case of bilateral lesions in bilateral hernia, 10 lesions were contralateral to the clinical hernias. In 1 case, lipomatous lesion was the sole finding with nonsignificant patent processus vaginalis. Every lesion was suture ligated and resected with gentle traction of the dissected hernia sac. It has not been clearly defined whether the lesion is a stopper or a provocator of the hernia development. However, removal is highly recommended to make a differential diagnosis from the recurrent inguinal hernia in future. The term "lipomatous lesion" seems to be pathologically accurate and must be differentiate from the true lipomas.
