Purpose: Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a congenital anomaly that can cause frequent digestive and nutritional problems, even after repair. The most common complication is anastomotic stricture, for which reoperation or balloon dilatation is performed. This study aimed to evaluate the postoperative complications of EA and the role of endoscopic balloon dilatation (EBD) in cases of anastomotic stricture. Methods: We retrospectively analyzed patients diagnosed with EA with or without TEF between January 2000 and February 2021. Patients' baseline characteristics, associated anomalies, and postoperative complications were reviewed. Results: Among 26 patients, 14 (53.8%) were male, 12 (46.2%) had coexisting anomalies, and the median follow-up was 6.1 years (range, 1.2-15.7 years). In univariate analysis, prematurity, low birth weight, and long-gap EA were associated with postoperative complications in 12 (46.2%) patients. Among the 10 (38.5%) patients with anastomotic stricture, nine (90.0%) required EBD. Regarding the first EBD, it was performed at a median of 3.3 months (range, 1.2-7.6 months) post-repair, while the average patient weight was 4.6 kg. The mean diameter ranged from 3.3 to 9.1 mm without major complications. In univariate analysis, long-gap EA alone was significantly associated with EBD. Conclusion: Approximately half of the patients experienced complications after EA repair. In particular, patients with a long-gap EA had a significantly increased risk of complications, such as anastomotic strictures. EBD can be safely used, even in infants.

Purpose: This study aimed to examine the effects abdominal breathing on anxiety and length of labor time in primipara women. Method: It was a quasi-experimental design with a non-equivalent comparison group, performed from October 11 to December 4, 2007. Thirty-six subjects who received pitocin and met the inclusion criteria were chosen by convenience sampling from the labor room of Y hospital located in Seoul. The intervention of abdominal breathing was 'four seconds of inhale, six seconds of exhale breathing method.' The abdominal breathing was carried out 30 times each when the uterine cervix was dilated $3{\sim}4cm$ and $5{\sim}6cm$. Psychological anxiety was measured by VAS-A before and after the cervix dilatation to $3{\sim}4cm$ and $5{\sim}6cm$. Result: Anxiety scores of the experimental was found lower than that of the control group at $3{\sim}4cm$(z=-3.05, p=.00) and $5{\sim}6cm$(z=-2.04, p=.04) of cervix dilatation. However, the abdominal breathing was not effective to the length of labor from the active phase thru full dilatation, though there was 56 minutes of difference between the two groups. Conclusion: Carrying out the abdominal breathing 30 times at two time points was effective in decreasing anxiety level during labor. Further study is suggested to examine the effects of abdominal breathing on labor time, fetal heart rate, and uterine contraction.

To ascertain residual sonographic and histopathological findings of clonorchiasis after treatment, the present study evaluated sonographic findings in rabbits which were infected with 500 metacercariae of C.sinensis every 6 months for 18 months after treatment with praziquantel. The sonographic findings were analyzed in terms of intrahepatic bile duct dilatation and periductal echogenicity, and histopathological findings were observed after the last sonographic examination. Compared with the sonographic findings before treatment, dilatation of the intrahepatic bile ducts became mild to some degree in four of the seven cases and increased periductal echogenicity resolved in four of them. The histopathological specimens after 18 months showed that periductal inflammation has almost resolved but moderate dilatation of the intrahepatic ducts and mucosal hyperplasia persisted. The periductal fibrosis minimally resolved. The log-lasting sonographic findings in cured clonorchiasis make sonography less specific.

Purpose: Our aim was the longitudinal assessment of cyst size in fetuses with biliary cystic malformation (BCM) to explore its etiology and the possibility of antenatal differentiation between biliary atresia (BA) and congenital biliary dilatation (CBD). Methods: We conducted a retrospective review of all patients diagnosed antenatally with BCM from 1994 to 2014 at our institutions. Results: The study cohort comprised of three patients with BA and six with CBD. There were no significant differences in the gestational age and cyst size at the first detection of BCM between the two groups. In fetuses with CBD, the cyst size steadily increased as the gestational age advanced, while it fluctuated around 1.5 cm and remained below 2.1 cm in those with BA. However, the ratio of cystic area to fetal trunk area was approximately constant due to linear fetal growth in fetuses with CBD. Conclusion: Fetuses with BCM <2.1 cm in the late gestation period were more likely to have BA than CBD. Our observation of cyst enlargement with advancing gestational age in the CBD group was attributed solely to fetal growth. Biliary dilatation in fetuses with CBD and BA might be completed at the onset of BCM.

Purpose: Nodal metastasis is the main prognostic factor in the patients with oral squamous cell carcinoma (OSCC). We investigated the association between tumor-associated lymphatics and OSCC characteristics. Methods: Thirty-four specimens were used for the immunohistochemical staining with the antibody for vascular endothelial growth factor (VEGF)-C, VEGF-D, VEGF receptor (VEGFR)-3, phosphorylated VEGFR-3, D2-40, and matrix metallproteinases (MMPs). We observed the distribution of the lymphangiogenic factors and quantified the degree of expression. We determined lymphatic vessel density (LVD) and lymphatic vessel dilatation with D2-40 immunostaining. We assessed the association of LVD or lymphatic vessel dilatation with tumor progression or tumor differentiation. Results: OSCC cells expressed lymphangiogenic ligands. Lymphangiogenic receptor, VEGFR-3, was expressed and activated in some tumor cells as well as in tumor-associated endothelial cells. LVD was not associated with tumor size or nodal status, but lymphatic vessel dilatation was higher in tumors with nodal metastasis, and also higher in poorly differentiated tumors. In stromal area of OSCC, MMP-1 and MMP-10 were up-regulated and the basement membrane of tumor-associated endothelial cells was destroyed by these collagenases. Conclusion: In the primary tumors with nodal metastasis, especially in poorly differentiated OSCC, tumor cells invaded the dilated lymphatic vessels via ruptured sites. MMP-1 and MMP-10 are important in the lysis of the glycocalyx inside the tumor-associated lymphatic endothelial cells.

Four dogs were presented with the history of progressive abdominal distension and regurgitation. Survey abdominal radiographs revealed gastric dilatation-volvulus (GDV) with a distended, gas-filled stomach and double bubbles. The mean time from onset of clinical signs to presentation to a clinic was 3.25 hours. In three dogs, orogastric tubes were inserted and their stomachs were decompressed. However, we failed to insert the tube in the remaining one dog. Among these four dogs, gastrotomy was performed in two dogs to remove the gastric contents and to decompress the stomach additionally during surgery. The dogs with GDV were treated with belt-loop gastropexy (n=3) or circumcostal gastropexy (n=1) to prevent recurrence. Necrosis of gastric or splenic tissues was not observed during surgical intervention. All four dogs recovered uneventfully, and no recurrence was found in long term follow-up during $1{\sim}3$ years.

The prevalence rate of pulmonary tuberculosis is 1.8% in 1990, and endobronchial tuberculosis may exist in 10 to 40% of active disease. Endobronchial tuberculosis usually leaves bronchial stenosis as the complication despite of modern chemotherapy, and it is often misdiagnosed as bronchial asthma. When bronchial stenosis involves major airway, its treatment needs such special measures as steroid therapy, surgical intervention and/or laser therapy, but the therapeutic result is often disappointing. To exploit a new treatment modality for bronchial stenosis, balloon dilatation was carried out in 12 patients with endobronchial tuberculosis. Under local anesthesia, 4F-Fogarty balloon was inserted via bronchofiberscope in ten cases and 10F-Gruentzig balloon was introduced under fluoroscopic guide in two others. Endobronchial tuberculoses were subdivided into two(16.7%) with actively caseating type, seven (58.3%) with fibrostenotic type, and three (25.0%) with stenotic type without fibrosis, according to the bronchoscopic findings. In 7 healed cases which were all stenotic with fibrosis, three (42.9%) took favorable turn in clinical status but four (57.1%) were not improved with balloon dilatation. In 5 active cases, all (two with actively-caseating type and three with stenotic type without fibrosis) were improved with this method. $FEV_{1.0}$ or FVC increased 10% or more after procedure in seven (70.0%) of ten and bronchial lumen remained enlarged in eight (66.7%) of twelve, in whom follow-up examination was done after the procedure. Balloon dilatation of bronchial stenosis is more effective, when endobronchial tuberculosis is in active stage than in healed fibrotic stage. It is suggested that bronchial stenosis can be minimized by early diagnosis and early application of balloon dilatation in the course of disease.
