Spontaneous perforation of CBD in infant is a rare but fatal disease. We report a case of bile leakage from common bile duct in 11 months old girl with progressive abdominal distension and vomiting, preoperatively diagnosed by hepatobiliary scan with 99mTc-DISIDA, which was confirmed by surgery, Operative cholangiogram showed a small perforation at the confluence of cystic duct and common bile duct with mild fusiform dilatation, and no definite abnormality in confluence of the common bile duct and pancreatic duct. Simple drainage of the free peritoneal bilous fluid and T-tube drainage were performed without any evidence of the complication. Patient was inevitable for 6 months OPD follow-up examination.

The nasopalatine duct cyst, known as the incisive canal cyst, is the most common nonodontogenic cyst in the maxillofacial area. It is believed to arise from epithelial remnants of the embryonic nasopalatine duct. Nasopalatine duct cysts are most often detected in patients between forties and sixties. The trauma, bacterial infection, or mucous retention has been suggested as etiological factors. The cysts often present as asymptomatic swelling of the palate but can present with painful swelling or drainage. Radiologic findings include a well demarcated cystic structure in a round, ovoid or heart shape presenting with a well-defined bone defect in the anterior midline of the palate between and posterior to the central incisors. Most of them are less than 2cm in size. On MRI, the cyst is identified as a high-intensity, well-marginated lesion, which indicates that it contains proteinaceous material. We experienced a case of a 61-year-old female patient who had a $2.3{\times}2.6{\times}1.7cm$ sized nasopalatine duct cyst. The bony defect after a surgical extirpation was restored with hydroxyapatite. So we report a good results with some reviews of the literatures.

Nasopalatine duct cysts are the most common non-odontogenic developmental cyst originating in the incisive canal of maxilla and occuring in approximately 1% of the population. Clinical presentation is mostly asymptomatic in small cysts, but sometimes shows swelling, pain and drainage when it is infected. The definite diagnosis should be based on clinical, radiological and histopathologic findings. Marsupialization of the cystic tissue can be performed, however, complete surgical excision is the the choice of treatment of nasopalatine duct cysts. We report a case of nasopalatine duct cyst occurred in the midline of hard palate treated by complete excision via transoral approach.

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.

들장관증후군은 위장 재건술을 동반한 위절제술 후 발생하는 드문 합병증이다. 이 질환은 담관염, 췌장염, 복막염을 동반한 십이지장 천공과 같은 치명적인 상태에 이를 수 있어서, 즉각적인 감압 치료가 필요하다. 담관 확장이 없는 들장관증후군 환자를 위한 대체 감압 치료법으로 경담낭 십이지장 배액술을 시행한 두 건의 증례를 보고하고자 한다. Billroth II 문합술과 위원위절제술을 시행한 2명의 환자가 상복부 통증과 구토를 주소로 응급실에 내원하였다. 컴퓨터단층촬영에서 급성 췌장염을 동반한 들장관증후군으로 진단되었다. 담관 확장이 없어 담도를 통한 접근이 어려워, 경담낭 접근을 통해 담낭관을 통과한 후 들장관을 감압하기 위한 십이지장 배액 카테터를 설치하였다. 환자들은 배액술 시행 후 각각 2주와 1개월째에 추가적인 수술적 치료 없이 퇴원하였다.

Background/Aims: Endoscopic ultrasound gallbladder drainage (EUS-GBD) is gaining attention as a treatment method for cholecystitis. However, only a few studies have assessed the outcomes of permanent stenting with EUS-GBD. Therefore, we evaluated the clinical outcomes of permanent stenting using EUS-GBD. Methods: This was a retrospective, single-center cohort study. The criteria for EUS-GBD at our institution are a high risk for surgery, inability to perform surgery owing to poor performance status, and inability to obtain consent for emergency surgery. EUS-GBD was performed using a 7-Fr double-pigtail plastic stent with a dilating device. The primary outcomes were the recurrence-free rate of cholecystitis and the late-stage complication-avoidance rate. Secondary outcomes were technical success, clinical success, and procedural adverse events. Results: A total of 41 patients were included in the analysis. The median follow-up period was 168 (range, 10-1,238) days. The recurrence-free and late-stage complication-avoidance rates during the follow-up period were 95% (38 cases) and 90% (36 cases), respectively. There were only two cases of cholecystitis recurrence during the study period. Conclusions: EUS-GBD using double-pigtail plastic stent was safe and effective with few complications, even in the long term, in patients with acute cholecystitis.

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is an uncommon congenital abnormality of the female urogenital tract characterized by the triad of uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. A 13-year-old female presented with acute lower abdominal pain. Magnetic resonance imaging (MRI) revealed uterine didelphys, hematometrocolpos, obstructed hemivagina, and right ipsilateral agenesis, consistent with OHVIRA syndrome. Also, a well-defined mass with fluid signal intensity, mimicking adnexal neoplasm was seen in the right lower pelvic cavity adjacent to the posterior wall of the bladder. Vaginal septotomy and drainage of hematometrocolpos were done initially, but unilateral hysterectomy was later performed to relieve the patient's symptoms. The cystic mass in the right lower pelvic cavity was also excised and confirmed as a blind megaureter.

Purpose: A nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst arising anywhere on the face inferior to the nasoalar region. It is thought to arise from either epithelial remnants trapped along the lines of fusion during the development of face or the remnants of the developing nasolacrimal duct. This study examines various features of nasolabial cysts with bony involvement to provide a basis for correct diagnosis and treatment. Methods: Eight cases of nasolabial cyst treated in Soonchunhyang Hospital between March 2002 and July 2010 were examined in terms of their clinical features and radiological and histological findings. Seven patients underwent surgical excision of the cyst via an intraoral, sublabial approach. One underwent incision and drainage. Results: Our eight patients were seven women and one man. The most frequent symptoms and signs were facial deformity and swelling of the nasolabial fold. Computed tomography (CT) showed a well-circumscribed cystic mass lateral to the pyriform aperture. Seven cases had erosive lesions on CT, and the intraoperative findings were consistent with a nasolabial cyst with a bony defect. Typical histopathological findings showed that these cysts were most frequently lined with respiratory epithelium with ciliated columnar cells and cuboid cells. No patient developed complications or recurrences. Conclusion: A nasolabial cyst is often unrecognized or confused with other intranasal masses, including fissural and odontogenic cysts, midface infections, or swelling in the nasolabial area. Therefore, a careful clinical and radiological evaluation should be preformed when considering the differential diagnosis. We present eight patients with nasolabial cysts treated via a gingivobuccal approach with excellent functional and cosmetic results.
