Fetal cardiac capillary hemangioma resulting in tachyarrhythmia.

We present the case of a fetus with cardiac capillary hemangioma in the right atrial cavity. The tumor showed dramatic growth between the 28th and 32nd week of gestation and resulted in tachyarrhythmia. The patient was born at the 33 weeks of gestation weighing 2430 g via urgent cesarean section because the rapidly growing cardiac tumor caused incessant tachyarrhythmia, pericardial effusion, and fetal circulatory incompetence. Coronary angiography revealed that the right coronary artery drained into the tumor. Due to hemodynamic deterioration, the patient underwent subtotal resection of the tumor on the 2nd day after birth. Histopathological examination revealed an undifferentiated capillary hemangioma. The patient was discharged at the age of 86 days, as the tachyarrhythmia and hemodynamic incompetence had subsided; however, bradycardia and intermittent atrioventricular conduction disturbance gradually developed. Capillary hemangioma, a rare primary cardiac space-occupying tumor in children, can invade the conduction system.

Abdominal esophageal banding for esophageal atresia with tracheoesophageal fistula in neonates with severe associated anomalies.

PURPOSE: The aim of this study was to evaluate the materials used for abdominal esophageal banding, and to evaluate the complications associated with abdominal esophageal banding. METHODS: The medical records of seven patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) who underwent abdominal esophageal banding between December 2009 and January 2020 were retrospectively reviewed. RESULTS: The patients were banded with vinyl tape (n = 1), silicone tape (n = 2), polyacetal resin clips (n = 1), or an expanded polytetrafluoroethylene (ePTFE) sheet (n = 3). Banding with vinyl tape resulted in banding failure at postoperative day (POD) 89. One patient with silicone tape developed banding failure at POD 177. In the other patient, it was discovered during radical surgery that the silicone tape had slipped through the abdominal esophagus. Polyacetal resin clip banding resulted in esophageal wall perforation at POD 27. One patient banded with an ePTFE sheet underwent upper gastric transection at POD 650, while another underwent TEF resection at POD 156; in the third patient, the banding condition was maintained for more than 100 days. CONCLUSION: Abdominal esophageal banding is useful as a palliative treatment for EA/TEF with severe associated anomalies. Surgeons should plan the next surgery depending on the patient's condition.

Impacts of surgical interventions on the long-term outcomes in individuals with trisomy 18.

OBJECTIVE: We aim to clarify whether surgical interventions can contribute to improve the long-term outcomes among individuals with trisomy 18. METHODS: We retrospectively studied 69 individuals with trisomy 18 admitted to 4 tertiary neonatal centers between 2003 and 2017. A cohort was divided into two groups: subjects with surgical interventions and conservative treatments. We compared the rates of survival and achieving homecare between the groups. RESULTS: Gestational age and birth weight were 37 (27-43) weeks and 1,700 (822-2,546) g, respectively. There were 68 patients with congenital heart disease and 20 patients with digestive disease. Surgical interventions including cardiac and digestive surgery were provided in 41% of individuals. There was no difference in gestational age (p=0.30), birth weight (p=0.07), gender (p=0.30), and fetal diagnosis (p=0.87) between the groups. During the median follow up duration of 51 (2-178) months, overall survival rates in 6, 12 and 60 months were 57%, 43% and 12%, respectively. Survival to hospital discharge occurred in 23 patients, and the rates of achieving homecare in 1, 6, and 12 months are 1%, 18% and 30%, respectively. There was no significant difference in survival rate (p=0.26) but in the rate of achieving home care (p=0.02) between the groups. Cox hazard analysis revealed that prenatal diagnosis (hazard ratio 0.30, 95%CI: 0.13-0.75), cardiac surgery (hazard ratio 2.40, 95%CI:,1.03-5.55), and digestive surgery (hazard ratio 1.20, 95%CI: 1.25-3.90) were related to the rate of achieving homecare. CONCLUSION: Aggressive surgical interventions contribute not to the long-term survival but to achieve homecare among individuals with trisomy 18. EVIDENCE LEVEL: Level 3 (Prognostic study, Case-Control study).

Prediction of Negative Outcomes in Non-Surgical Treatment for Appendiceal Abscess in Adults.

OBJECTIVES: Non-surgical treatment is an acceptable approach for managing appendiceal abscess in adults. However, it is only applicable for selected patients, and conversion to surgery is mandatory for failed conservative treatment. This study aimed to determine the predictive factors for unsuccessful outcomes. METHODS: Of 594 patients with acute appendicitis, 34 (5.7%) diagnosed with appendiceal abscess were initially treated conservatively. Patients were divided into two groups: the conservative group, which was successfully treated with antibiotics and percutaneous abscess drainage, and the conversion group, which comprised patients who had surgical conversion despite conservative treatment. Risk factors for the conversion group were investigated by comparing clinical and radiological parameters between the two groups. RESULTS: Eight (23.4%) patients were converted to surgical management at an average of 5.5 days of non-surgical treatment. An abscess size greater than 40 mm and a lower rate of improvement in the white blood cell (WBC) count were significant factors for predicting conversion in multivariate analysis. The conversion group had a long operative time and high morbidity and operative conversion rates (change of proposed initial operation). Early conversion to operation group, i.e., less than 5 days of treatment, contributed to a significantly shorter hospital stay, lower hospital cost, and relatively shorter operative time (p = 0.02, p = 0.04, and p = 0.11, respectively). CONCLUSIONS: Contributing factors in predicting unsuccessful outcomes for non-surgical treatment include an abscess size greater than 40 mm and a low rate of improvement in WBC count on the first day of antibiotic treatment.

Internal hernia after laparoscopic gastrectomy with Roux-en-Y reconstruction for gastric cancer.

BACKGROUND/OBJECTIVE: Laparoscopic gastrectomy (LG) is increasingly used to treat gastric cancer. Simultaneously, internal hernia (IH) has been reported after LG with Roux-en-Y reconstruction (RY). The aim of this study was to investigate IH after LG with RY for gastric cancer. METHODS: This study included 15 patients with IH from a database of 355 consecutive patients who underwent LG with RY for gastric cancers. We retrospectively analyzed IH incidence and clinical characteristics by operative procedures. RESULTS: The total incidence of IH was 4.2%. The incidence of IH at Petersen's defect tended to decrease with modifications to the reconstruction methods, but not significantly so. The incidence of IH at jejunojejunostomy mesenteric defect significantly decreased with closure of this defect (p = 0.01). The incidence of IH at transverse mesocolic defect was 1.3% in patients who underwent retrocolic RY; emergent small-bowel resection was only required in two cases of herniation through this defect after laparoscopic total gastrectomy. CONCLUSION: Retrocolic RY with appropriate closure of defects can reduce IH incidence at Petersen's defect and at jejunojejunostomy mesenteric defect. Although the IH incidence at the transverse mesocolic defect is not particularly high, the possibility of herniation through this defect should be kept in mind.

Electrophysiological properties of the aganglionic segment in Hirschsprung's disease.

BACKGROUND: In Hirschsprung's disease, the severity of bowel obstruction varies among those patients who have the affected colon of a similar length, suggesting that there is more than a simple aperistaltic obstruction in the pathophysiology of Hirschsprung's disease. METHODS: A series of our electrophysiological studies of the aganglionic segments from human specimens and rat models were reviewed to obtain an overview of Hirschsprung's disease. RESULTS: In human studies, a generation of regular spontaneous activity was recorded in both the dilated ganglionic segment and transitional aganglionic region, while the smooth muscle cells of the narrow aganglionic segment were electrically quiescent. According to a pattern of innervation, in the dilated ganglionic segment inhibitory junction potentials associated with or without excitatory junction potentials were observed in all of the examined cells, and these intrinsic nervous inputs were gradually decreased in the transitional region. In the narrow aganglionic segment, only excitatory junction potentials of the extrinsic nervous origin were found in about 20% of the examined cells In rat models, distally increasing tendency of the excitatory nervous inputs was observed in the narrow aganglionic segment. CONCLUSION: A bowel obstruction in Hirschsprung's disease might be generated due to complex mechanisms involving myogenic and neurogenic abnormalities.

Malignant serous cystic neoplasm of the pancreas: report of a case and review of the literature.

BACKGROUND: In general, serous cystic neoplasms of the pancreas are thought to be benign. Malignant serous cystic neoplasm of the pancreas is a rare clinical entity. CASE REPORT: We report the case of an 87-year-old woman with a serous microcystic neoplasm in the tail of the pancreas that behaved in a malignant fashion. The neoplasm had also invaded the colonic mesentery and splenic hilum. The pancreatic lesion was diagnosed as a large malignant serous cystic neoplasm, and the patient underwent distal pancreatectomy with splenectomy and segmental colectomy. The resected specimen contained a large tumor, 12 x 9 x 8 cm, which occupied the body and tail of the pancreas. Histologically, the tumor was indistinguishable from serous cystadenoma. However, the tumor had invaded surrounding tissues including the splenic vein, and there were splenic invasion and a regional lymph node metastasis. The postoperative course was uneventful. DISCUSSION: There are few reported cases of malignant serous cystic neoplasm, in which malignancy was histologically confirmed in the resected specimen. There are no reports of a negative outcome with complete resection of the tumor. Surgical treatment should be considered for serous cystic neoplasms, especially large ones, because of the malignant potential.
