Thymolipoma is a rare benign mediastinal tumor, composed of mature fatty and thymic tissues. A 9-year-old boy was referred with a one-month history of neck swelling. Preoperative computed tomography scan and fine needle aspiration biopsy suggested thymolipoma. Despite it being rare, thymolipoma should be considered in the differential diagnosis of mediastinal tumors. Characteristics of its clinical feature and radiological findings that can differentiated it from other mediastinal tumors are discussed with a review of the literatures.

Conventional hemorrhoidectomy is still the main stairway to the treatment of the third or the fourth degree hemorrhoids. Among the various methods of hemorrhoidectomy, open hemonhoidectomy is claimed to decrease postoperative pain and wound infection, but to have disadvantage of long period of wound healing. Semi-closed hemorrhoidectomy has the advantage of rapid wound healing without increased risk of wound infection, but more painful postoperative course than open hemorrhoidectomy is suggested. To assess this conventional concept, two hundreds of patients were randomly allocated to either an open hemorrhoidectomy(Group 4, Operated by modified Goligher method, n=100) or a semi-closed hemorrhoidectomy(Group B, Operated by modified Nesselrod method, n=100), and postoperative results were analyzed. In group 4, the average time for disappearance of wound edema was 4.9days, average time for disappearance of wound pain was 9.0days, average time for painless defecation was 14.1 days, average time for complete wound healing was 28.4days. The main complications were overgranulation, skin tag, anal discharge and pruritus. The overgranulation requires curettage, the skin tags were resected under local anesthesia. Anal discharge and pruritus were spontaneously disappeared after the healing of the wound. In group B, the average time for disappearance of wound edema was 6.1 days, average time for disappearance of wound pain was 6.3days, average time for painless defecation was 9.2days, average time for complete wound healing was 20.7days. The main complications were skin tags, more prevalent than group 4, requiring resection under local anesthesia. No infectious complications were noted in both groups. Consequently, the old concept that open hemorrhoidectomy has advantage of less painful postoperative course than semiclosed hemorrhoidectomy cannot be accepted. Semi-closed hemorrhoidectomy offers more rapid loss of pain and more rapid healing of the wound than open hemorrhoidectomy, without increased risk of infectious complications. In conclusion, semi-closed hemorrhoidectomy is superior method to open hemorrhoidectomy in third or fourth degree hemorrhoids.

Several investigators have attempted to clarify th well-known phenomenon of anergy in lepromatous leprosy during past two decades, utilizing various methods of immunologic assessrvent, including response to skin test antigens, active skin sensitization with strong allergens, skin homograft survival rate, imrnunopathology of lymphnodes, in vitro blastogenic response by antigens or mitogens of lymphocytes, lymphokine production in vitro and measurement of peripheral T and B cell ratio. Howcver, there is no general agreement as to the cellular irnmunologic status of leprosy patients b tween various investigators. The present study was undertaken to evaluate the ability to mount cutaneous hypersensitivity reactions to various skin test antigens and to investigate active sensitization with DViCB in patients with leprosy. Ten polar lepromatous (LL) and 12 polar tuberculoid (TT) p-tients who have been treated at Department of Dermatology, National Iviedical Center and Seoul Nationa,l University Hospital were the subjects. The subjects have rcceived regular antileprosy chemotherapy with DDS and the average duration of treatment in LL and TT groups was 6. 2 and 4. 7 years, respectively. The control group included 10 healthy physicians and nurs-s. Skin test antigens includ=d lepromin (1 x10' bacilli,ml'), PPD (Parke-Davis 5ppJ/0.1ml), SK-SD (Lederle, 40 u SK and 10 u SD/0.1 ml), Candidin (Hollister stier Lab 1: 1000 dilution) and DNCB aceton solution in the concentrations of 1000ug,/0.1ml for sensitization and 100ug/0.1ml for challenge, respcctively. Skin reactions were read 48 hours after intraderrnal injection of 0.1 rnl of each antigen anci th.' metho4 of DNCB sensitization was same as described elsewhere. The result showed that in polar lepromatous leprosy patients, the skin reactivity to various antigens were generally decroased, as cornpared to both th healthy control group and polar tuberculoicl patients, especially to lepromin, PPD and I')NCB sensitization (p<0.05, respectively). We concluded thxt lepromatous leprosy patients were especially unresponsive to mycobacterial antigcns(lepromin and PPD) and to newly administered antigen (DNCB) and tbe possible mechanism was discussed.

A choledochal cyst is a relatively common lesion of the biliary tract in pediatric patients and usually presents abdominal pain, jaundice, and abdominal mass. Its etiology is unknown, but the theory of pancreatobiliary reflux through anomalous pancreatobiliary duct union is widely accepted. A mucinous cystadenoma of the pancreas is very rare in children. To our knowledge, there is no literature reporting a case of a choledochal cyst with a mucinous cystadenoma of the pancreas. We report a case of a choledochal cyst combined with a mucinous cystadenoma of borderline malignancy at the head of the pancreas in a 5-year-old girl and review the literature.

Ileovesical fistula is a rare condition in children. A case of 13 year-old female with ileovesical fistula caused by an ingested foreign material is presented. She had dysuria and lower abdominal pain for one month. There was no history of medico-surgical illness such as Crohn's disease or diverticulitis. Preoperative imaging study showed a movable calcified object in the pelvic cavity and air bubbles in the bladder. At laparotomy a bezoar-like mass was found at the antimesenteric border of the terminal ileum adherent to the dome of bladder. Segmental resection of the ileum and partial cystectomy were performed.

The majority of the cysts developed in pancreas are inflammatory pseudocyst but neoplastic cysts are rarely encountered Especially, mucinous cystadenoma which was begun and originated from epithelial cell of pancreatic duct is difficult to differentiate from pseudocysts by preoperative clinical, laboratory and radiologic findings. Mucinous cystadenoma has a malignant potentiality, so complete excision of cystadenoma is the treatment of choice. Recently, we experienced one case of mucionus cystadenoma in 37 year-old female, we report it with a review of the literature.

Infantile hypertrophic pyloric stenosis (HPS) is a relatively common entity. A number of studies for the postoperative feeding schedule has been studied to allow for earlier hospital discharge and improve cost-effectiveness in the treatment of HPS. The purpose of this study was to compare 3 feeding-methods and to evaluate the usefulness of ad lib feeding for HPS. The authors retrospectively reviewed the records of 116 patients who underwent pyloromyotomy for HPS from 1995 to 2004. Three cases were excluded because of the duodenal perforation during pyloromyotomy. Three feeding-methods were defined as: Conventional feeding (>10 hours nothing by mouth and incremental feeding every 2 hours, C), Early feeding(for 4 to 8 hours nothing by mouth and incremental feeding every 2 hours, E), and Ad lib feeding (for 4 hours nothing by mouth and ad lib feeding, A). Time to normal feeing in C, E and A were 51+/-24, 34+/-12 and 24+/-6 hours, respectively. Hospital-stay in C, E and A were 72+/-17, 55+/-13 and 43+/-12 hours, respectively. There were statistically significant differences according to the method of feeding. Frequency of postoperative emesis in C, E and A were 38%, 47% and 53%, but was not significant statistically. Ad lib feeding decreased time to normal feeding and hospital stay, and did not increase postoperative emesis. We conclude that ad lib feeding is recommended for patient with pyloromyotomy in HPS.

BACKGROUND: The etiology of choledochal cysts is unknown, but the theory of pancreatobiliary reflux through an anomalous pancreatobiliary ductal union (APBDU) is widely accepted. The aim of this study was to evaluate the correlation between choledochal cysts and APBDUs in children. METHODS: We retrospectively analyzed 33 pediatric patients with choledochal cyst who had undergone excision of the whole extrahepatic bile duct along with hepaticoenterostomy at the Division of Pediatric Surgery, Department of Surgery, Yonsei University College of Medicine, from 1993 to 1998. RESULTS: The mean age of the patients was 51 months, and the ratio of males to females was 1:2.3. Anatomical types were Ia (n=17, 52%), Ic (n=11, 33%), III (n=1, 3%), and IVa (n=4, 12%) in the Todani classification of biliary cysts. We performed endoscopic retrograde cholangiopancreatography, magnetic resonance cholangiopancreatography, or intraoperative cholangiopancreatography in all cases. An APBDU was identified in 24 patients (73%): right angle union (n=11, 33%), acute angle union (n=11, 33%), or a complex union (n=2, 6%) in the Todani classification of APBDUs. Type Ia cystic lesions correlated with right angle unions whereas Type Ic cylindrical lesions correlated with acute angle unions. The mean age of patients with a Type Ic, acute angle union was older than that of patients with a Type Ia, right angle union. In Type Ic, the amylase levels in serum and bile were elevated, but in Type Ia, they were not. CONCLUSIONS: APBDUs correlated highly with the shape of the extrahepatic dilatation, the age at onset, and the reflux of pancreatic juice. We think the excision of the entire extrahepatic duct along with a hepaticoenterostomy and appropriate evaluation of the APBDU are essential for the treatment of choledochal cysts in children.

Appendicitis is a common disease in children. But left lower abdominal pain in acute appendicitis is a rare clinical feature. A 6 year-old-girl complained of left sided abdominal pain for 2 days. Past medical history was not contributory. Abdominal tenderness and guarding in left lower quadrant were noticed. Abdominal sonography and abdominal computed tomography scan demonstrated reversed position between superior mesenteric artery and vein, and a mass in the left lower quadrant abdomen suggesting appendicitis. Acute appendicitis in left lower quadrant, associated with intestinal malrotation, was found at laparatomy.

The purpose of this study was to evaluate the frequency of congenital missing teeth and supernumerary teeth in cleft patients. The subjects were divided into bilateral cleft lip and palate(BCLP), unilateral cleft lip and palate(UCLP) and cleft palate alone(CP alone) groups. 97 cleft patients(BCLP 15, UCLP 70, CP alone 12) between 6-20 years old were evaluated. Panorama film, Orthodontic chart and initial intraoral photogram were employed for this research. The obtained results were as follows. 1. The incidence of congenital missing teeth in total cleft samples was 57.7 %, and the incidence of supernumerary teeth was 26.8 %. Each incidence was higher than non-cleft. 2. The incidence of congenital missing teeth was the highest in BCLP and the lowest in CP alone. 3. The number of congenital missing teeth per perso was usually one, and the frequency was higher in the maxilary lateral incisors(67.8 %), and maxillary second premolar(14.9 %) than other teeth. 4. Most of tooth number anomalies in cleft patients were found in maxilla, especially adjacent region to the cleft site.
