The length, diameter and muscle thickness of the pylorus were measured by ultrasonograms in 15 infants with infantile hypertrophic pyloric stenosis(IHPS). These measurements were compared to assemble measurements of infants who came in for the routine vaccination and underwent ultrasonogram. This study also studied by ultrasound the changes in the pylorus of patients who underwent pyloromyotomy 4 weeks and 8 weeks postoperatively. According to $Carver^5$, the pyloric muscle volume(PMV) and pyloric muscle index(PMI) were calculated in each case. The pyloric muscle volume, PMI and the thickness of pyloric muscle proved to be a more reliable guide to diagnose IHPS than length and diameter of pylorus. The pyloric muscle length, diameter, thickness and pyloric muscle volume were not normalized at 4 and 8 weeks after pyloromyotomy. However, pyloric muscle index was normalized at 4 weeks postoperatively perhaps as the result of rapid weight gain after pyloromyotomy.

Appendicitis is the most common surgical emergency in childhood and the technologic advances of modern medicine have affected the diagnosis and treatment of appendicitis. This study is to evaluate the differences in diagnosis and treatment of appendicitis between present and 10 year ago. The authors retrospectively reviewed the medical records of patients who underwent appendectomy under the diagnosis of the acute appendicitis from July 1993 to June 1995 (Group A, n = 78) and from July 2003 to June 2005 (Group B, n = 105). There are no differences between group A and B in mean age ($8.5{\pm}3.6$ vs. $9.3{\pm}3.1$ year), duration of symptoms ($3.0{\pm}3.2$ vs. $2.6{\pm}3.8$ days), and postoperative hospital stay ($6.6{\pm}4.8$ vs. $5.8{\pm}3.6$ days). Preoperative abdominal ultrasonogram and/or computed tomogram was performed in 7 patients (9.0 %) of group A and in 51 patients (58.5 %) of group B. Thirty-six patients (34.3 %) of group B underwent laparoscopic appendectomy, but none in group A. Incidence of a histologically normal appendix decreased from 15.8 % in group A to 4.8 % in group B (p =0.018). This study suggests that utilization of abdominal ultrasonogram or computed tomogram in preoperative evaluation become more popular and surgical treatment of acute appendicitis become more minimally invasive. The rate of negative appendectomy was also reduced compared with 10 year ago.

Purpose: The purpose of this study is to demonstrate the usefulness of the high resolutional ultrasonographic features in patients with foreign body. Methods: From September 2007 to August 2009, we retrospectively reviewed high resolutional ultrasonogram using 5~12 MHz linear transducer of 13 patients presenting with inflammation after foreign body injection. They were referred for complications after foreign body injection. Injected foreign bodies were 4 silicone, 4 paraffin, 2 artecoll, and 3 unknown. We treated them with foreign body removal (7), foreign body removal and corrective plastic surgery (4), and conservative treatment with antibiotics and steroid injection (2). Results: High resolutional ultrasonography well demonstrated the existence of foreign body and it's overall size, location within the tissue layer, and vascularity. Comparison between preoperative and postoperative ultrasonographic findings was useful not only to evaluate the prognosis but also to plan the treatment. These ultrasonographic findings aided in precise assessment of the contour and location of the foreign body and led to an accurate surgery. We were able to acquire various information in order to set a detailed plan for the operation which in turn, led to a precise, successful surgery. After the treatment, complication did not occur in 12 patients, except 1 patient. But this patient was also treated after reoperation. Postoperative high resolutional ultrasonography shows almost foreign body removed and inflammation disappeared. Conclusion: Considering the usefulness of highresolution ultrasonography in foreign body injection, highresolution ultrasonography would be necessary for both the patient and the doctor. Preoperative and postoperative high resolutional ultrasonography is highly accurate, safe, inexpensive and easy. It can be a useful modality in foreign body after plastic surgery.

Spontaneous perforation of the bile duct in children is a very rare disorder. We experienced a 6 year-old girl with spontaneous perforation of the right hepatic duct. The patient was initially misdiagnosed as hepatitis because of elevation of liver enzyme and then as appendicitis because of fluid collection in the pelvic cavity demonstrated by ultrasonogram. A laparoscopic exploration was done and no abnormal findings were detected except bile-stained ascites. Peritoneal drainage was performed and the patients seemed to improve clinically. Abdominal pain, distention and high fever developed after removal of the drains. DISIDA scan showed a possible of bile leak into the peritoneal cavity. ERCP demonstrated free spill of dye from the right hepatic duct. At laparotomy, the leak was seen in the anterior wall of the right hepatic duct 2cm above the junction of the cystic duct and common hepatic duct. The perforation was linear in shape and 0.8cm in size. The patient underwent cholecystectomy, primary closure of the perforation and T-tube choedochostomy. We could not identify the cause of the perforation; however, the T-tube cholangiography taken on the 42nd postoperative day showed a little more dilatation of the proximal common bile duct compared with the cholangiography taken on the 14th day. Long-term follow-up of the patient will be necessary because of the possibility for further change of the duct.

Purpose: We evaluated the results of treatment and clinical symptoms of 11 cases of synovial chondromatosis in the ankle joint. Material and Method: From February 2001 to May 2008, 11 cases with synovial chondromatosis involving ankle joint underwent surgical treatment. There were 5 males and 6 females. The average age at surgery was 51 years. The average follow-up period was 42 months. Duration from onset of symptom to treatment was 117 months. Chief complaints of patients, 9 cases were pain and 1 case was mass like lesion, 1 case was found on x-ray. Preoperatively, all cases were evaluated on simple x-ray, 4 cases on CT, 4 cases on MRI and 1 case on ultrasonogram. 10 cases underwent synovectomy and loose body removal. 5 cases of 10 cases underwent open synovectomy and loose body removal and arthrosocpic surgery. 4 cases of 10 cases underwent only open synovectomy and loose body removal and 1 case of 10 cases underwent only arthroscopic surgery. 1 case underwent tibiotalar arthrodesis. Results: The location of loose bodies was 7 cases on posterior and 4 cases on anterior and 4 case on lateral and 3 cases on multiple site. Postoperatively, all patients showed marked clinical improvement and had subjective satisfaction except reoperation 2 cases and arthrodesis 1 case. AOFAS score of all patients was average 82.2. Conclusion: Clinical results of the synovial chondromatosis of ankle joint were satisfactory. More accurate preoperative evaluation is required to achieve prevention of postoperative recurrence and better outcome.

After transplantation of groin free flap was sucessed by the Daniel and Taylor in 1973, the reconstruction of plastic surgery was extensive and universal due to rapidly developement of anatomic study of the donor site and technique of microvascular surgery. The free tissue transfers is possible to be early activity and rehabilitation by one stage operation. It currently available allow transfer of specific tissue quality as bone, muscle, nerve to achieve a functional and cosmetic result as well as the most favorable secondary defect. But free flaps require critical, skillful technique and lengthy operating time. Also it has disadvantage of donor site morbity at the large tissue transfer. Authors were transferred with 107 cases in 103 patients from May 1987 to June 1996, and then we analysed free tissue transfer to acquire more increased sucess rate, satisfactory functional and cosmetic results. The sexual distribution was male prominent in 79 cases(76.7%), female in 24(23.3%) and age was variable distribution from 3 to 76 years old. The cause of defects was most prevalent in trauma of traffic and industrial accident in 51 cases(49%). The common recipient site were lower extremities in 47 cases(43.9%), upper extremities in 28 cases(26.5%), head and neck in 25 cases(23.4%), and trunk in 7 cases(6.5%). The type of transfer were free skin flaps in 46 cases(43%), free muscle or musculocutaneous flaps in 31 cases(29%), free vasculized or osteocutaneous flaps in 10 cases(9.3%), and specilized free flaps in 20 cases(18.7%). The anastomosis of artery was end to end anastomosis in 94 cases(87.9%), end to side anastomosis in 13 cases(12.1%) and all vein was end to end anastomosis. The number of anastomosed vessels were one artery one vein in 62 cases(57.9%), one artery two vein in 45 cases(42.1%) and vein graft was performed only one case. The postoperative mornitoring were used with temperature, color of flap, capillary refilling time, ultrasonogram, bone scan, doppler, and endoscopy. The reexploration was performed in 9 cases(8.4%), and then flap was loss in 3 cases(2.8%). Accordingly overall success rate was 97.2%. The postoperative complication was early vascular occlusion, hematoma, partial necrosis and late bulkiness, scarring, color dismatch etc. Therefore, free tissue transfer is the preferred method of treatment, even through conventional local and distant flaps are available.

목 적 : 서혜부 탈장은 소아에서 비교적 흔하지만, 여아 탈장의 15-31%를 차지하는 난소 탈장은 아직까지 정립된 치료 원칙이 없고 국내에서는 질병의 경과에 대한 보고가 없다. 이에 연구자들은 난소 탈장 환아들의 특성과 임상 경과에 대하여 알아보고자 하였다. 방 법 : 2001년 3월부터 2007년 2월까지 관동대학교의과대학 제일병원에서 난소 탈장으로 진단받은 1세미만 여아 8명을 대상으로 환아들의 재태 연령, 출생체중, 난소 탈장 발견시기와 주 호소, 수술 시기 및 수술법, 수술 후 합병증 여부, 현재의 상태, 서혜부 초음파결과를 의무기록지와 전화 통화를 통해 후향적으로 조사하였다. 난소 탈장은 서혜부 종괴 여부와 초음파 검사 결과 난소가 서혜부에 위치하는 경우에 진단하였다. 결 과 : 환아들의 재태 연령은 $32^{+5}-40^{+1}$주 범위였으며, 이 중 37주 미만 미숙아는 4명(50%)이고, 출생체중은 1,600-3,505 g 범위였다. 대상 환아 중 7명(87.5%)은 좌측 난소 탈장이 있었으며, 1명(12.5%)은 우측에 난소 탈장이 있었다. 종괴를 발견한 시기는 생후 13-144일 사이로 다양하였으며, 수술 받은 환아들의 수술시기는 생후 50${\pm}$15일(35-65일)이었다. 현재까지 8명중 5명이 탈장 봉합술을 시행 받았으며, 합병증은 없었다. 수술을 시행하지 않은 3명은 경과 관찰 중에 수술없이 저절로 정복되었으며, 종괴가 사라진 나이는 생후121${\pm}$46일(70-161일)이었고, 관찰 기간 중(69-1,925일)감돈이나 재발은 없었다. 결 론 : 미숙아 여아인 경우 탈장의 빈도가 만삭아에 비해 높으므로 신체 검진을 통한 대음순 종괴의 발견이 중요하며, 초음파 검사를 통하여 확진한다. 소아의 난소 탈장은 아직까지 일관된 치료 방침이 없고, 외과의 의견을 따라 가능한 한 빠른 시일 내에 수술을 시행하였었기에 경과를 제대로 알 수 없었으나, 저자들이 경과 관찰을 하던 3명의 여아에서 생후 6개월 이내에 난소탈장이 저절로 정복되는 예를 경험하였고, 관찰 기간동안 재발은 없었다. 난소 탈장의 환자를 대상으로 추적관찰을 하여 적절한 치료 방침을 마련하여야 하겠다.
