Three hundred and twenty-seven patients of 2,046 inguinal hernia cases Primarily repaired at Hanyang University Hospital had the history of incarceration or presented as incarcerated inguinal hernia on admission. Incidence of incarceration of all male hernias was 14.2%(234 patients) and 22.7%(93 patients) of all female cases. Incarceration occurred in 17.3% of all right hernia cases and in 13.7% of all left hernia cases. The incarceration occurred 52.6% of the hernia patients in the first month of life, 27.3% in the first year, 26.7% in the second year and 7.8% after 2 years of age. Strangulated inguinal hernia occurred in 8 patients: five patients had ovaries involved, two patients intestines, and one patient omentum. Emergency operations were performed on 66 patients(20.2%) because incarcerated hernia could not be reduced by taxis. At the time of operation, the hernia sacs were empty in 140 of 327 patients and the remainders contained omentum(50), small intestine (44), appendix and/or cecum(28), sigmoid colon(2), ovary and/or tube(66), and omental cyst(1). An elective hernia repair should be performed promptly after presentation of the hernia, especially before 2 years of life because of high incidence of incarceration. In this study, of 327 incarcerated hernia, 187 patients(57.2%) did not have prior history of incarceration and incarceration developed more than 7 days after hernia onset in 95.6%. If the hernia repairs had been performed within 7 days after hernia onset, about half of the incarceration might have been prevented.

Congenital diaphragmatic hernia through Bochdalek foramen, posterolateral diaphragmatic hernia, is the result of a congenital malformation of the posterolateral region of the diaphragm. Bochdalek hernia is the most common type of congenital diaphragmatic hernia, but it is a extremely rare anomaly which is detected in adulthood because it has severe cardiopulmonary and gastrointestinal symptoms after birth immediately.We experienced two cases of Bochdalek hernia which were detected in adulthood. Among them, one was a 43 years old man who was treated with simple closure in left Bochdalek hernia and the other was 41 years old woman who was treated with patch closure using silastic sheet in right Bochdalek hernia. Their postoperative courses were uneventiful. So we report two cases of rare Bochdalek hernia which was detected in adulthood with review of literatures.

The clinical experience of 2,340 inguinal hernia repaired by one pediatric surgeon on 2,079 children at Hanyang University Hospital from September 1979 to December 1993 was analyzed. Of 2,046 patients who had primary hernia repairs at Hanyang University Hospital, 1,636 were male and 410 female, and 55.5% of hernias occurred on the right side, 36.0% on the left, and 8.6% were bilateral. The patients presented hernia under the age of 12 months were 45.3% and those performed herniotomy under the age of 12 months were 25.5%. Birth weight was less than 2.5kg in 111 patients(8.7%) of 1,279 data available patients. Ninety(6.6%) of 1,354 data available patients were premature(<37wks gestation). The proportions of bilateral inguinal hernia and the onset age under 12 months of life in low birth weight babies and premature babies were higher than in full-term babies. Incarcerated inguinal hernia occurred in 327 patients(16.0%) of whom 8 patients were strangulated hernias. The occurrence of incarceration inversely related with age of patients. The subsequent contralateral inguinal hernia following unilateral hernia repairs occurred in 80 patients(4.3%) among which 72 were male and 8 were female. The incidence of contralateral inguinal hernia was more frequent in boys(4.8%) than girls (2.2%) and in cases after left herniotomy(6.4%) than after right herniotomy(2.9%). Sixty percent of contralateral inguinal hernia developed within 1 year after primary hernia repair. The recurrence of inguinal hernia occurred in 6 patients(0.27%) treated at our hospital primarily. There were one or more associated congenital anomalies in 83 patients of which congenital heart diseases were the most common. Sliding hernia occurred in 25 patients consisted of 5 boys and 20 girls. Family history was noted in 35 patients and there were 28 sets of monozygotic and 3 sets of dizygotic twins.

Between June 1981 and April 1994, 15 patients underwent surgical repair of diaphragmatic hernia. The ages ranged from 1 day to 60 years, with a mean age of 34. There were 5 cases of congenital diaphragmatic hernia; Bochdalek hernia in 4 cases and Morgagni hernia in 1 case. There were 10 cases of traumatic diaphragmatic hernia;blunt trauma in 8 cases and stab wounds in 2 cases. The chest X-ray findings were abnormal in 10 cases. Operations were performed in all patients and there was only one death, who was a newborn with left Bochdalek hernia and pulmonary hypoplasia.

The term "Littre's hernia" was originally defined by Reinke in 1841 as "the presence of a Meckel's diverticulum in any hernia sac." Littre's hernia is a very rare disease, which accounts for less than 1 % of all Meckel's diverticula. We report a case of Littre's hernia experienced in a 45 day-old infant.

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.

Esophageal hiatal hernia is the hernia of a part of or the whole of stomach to posterior mediastinum through esophageal hiatus. Esophageal hiatal hernia can be classified as sliding hiatal hernia (type I), paraesophageal (type II), combined sliding and paraesophageal (type III), and complex paraesophageal (type IV). Type III and IV are clinically classified as paraesophageal hernia. The authors by chance found cystic mass filled with air in the lower lobe of the right lung during the treatment of mycoplasma pneumonia of 10 month-old patient. It was found to be paraesophageal hernia on the chest computed tomography and treated with the operation. As complex paraesophageal hernia is not usual among infants, the authors report it here with literature review.

We herein report a very rare case of adult right-sided Bochdalek hernia accompanied with hepatic hypoplasia and inguinal hernia. A 29-year-old man was admitted with right-sided pneumothorax. A computed tomography was performed and revealed large right sided Bochdalek hernia with hepatic hypoplasia. Under thoracolaparotomy, the defect was closed with Gore-Tex soft tissue patch. After the operation, left-sided inguinal hernia was found. However, it turned out that it had been present during infancy and spontaneously resolved during adolescence. This is the first report of right-sided Bochdalek hernia with hepatic hypoplasia and inguinal hernia in an adult.

Peritoneal dialysis (PD) has been utilized for the children with end stage renal disease. Nevertheless, it is thought to promote inguinal hernia by increasing intraabdominal pressure. To investigate the clinical characteristics of inguinal hernia in children on PD, 155 cases of PD in children between January 1996 and June 2007 at Seoul National University Children's Hospital were reviewed retrospectively. Inguinal hernia developed in 16 cases (10.3 %, M:F=8:8). Hernia occurrence was not correlated to age. Eleven cases (69 %) of inguinal hernia developed in first 6 months after initiation of PD. All inguinal hernias were surgically repaired. No complications occurred related to inguinal hernia or surgery. Recurrent hernia developed in 1 patient (6.3 %) of 2 cases who had PD postoperatively on the day of surgery. In conclusion, inguinal hernia developed more frequently with children on PD than general population (3.5~5 %). The rate of hernia development was highest within the first 6 months following initiation of PD. After repair of hernia, we recommend to discontinue PD immediate postoperatively to prevent recurrence.
