ABSTRACT

Background/Aims@#Bleeding is a complication of endoscopic snare papillectomy for ampullary tumors. This study aimed to investigate the clinical efficacy of hypertonic saline-epinephrine (HSE) local injection before endoscopic papillectomy for prevention of bleeding. @*Methods@#We retrospectively reviewed the data of 107 consecutive patients with ampullary tumors who underwent endoscopic papillectomy. The rates of en bloc resection, pathological resection margins, and prevention of immediate or delayed bleeding in the simple snaring resection group (Group A) and the HSE injection group (Group B) were compared. @*Results@#A total of 44 and 63 patients were enrolled in Groups A and B, respectively. The total complete resection rate was 89.7% (96/107); the clinical complete resection rates in Group A and Group B were 86.3% (38/44) and 92.1% (58/63), respectively (p=0.354). Post-papillectomy bleeding occurred in 22 patients. In Groups A and B, the immediate bleeding rates were 20.5% (9/44) and 4.8% (3/63), respectively (p=0.0255), while the delayed bleeding rates were 7% (3/44) and 11% (7/63), respectively (p=0.52). The rates of positive horizontal and vertical pathological margin in both groups were 27% and 16%, respectively. @*Conclusions@#HSE local injection was effective in preventing immediate bleeding and was useful for safely performing endoscopic papillectomy for ampullary tumors.

ABSTRACT

Urgent surgical repairs were successfully performed in four patients with blunt traumatic ruptures of the thoracic aorta. All 4 patients were involved in traffic accidents and had ruptures immediately distal to the aortic isthmus. The diagnoses were achieved by IV-DSA in case 1, by IV-DSA and enhanced CT in case 2 and by enhanced helical CT in cases 3 and 4. Intraoperative transesophageal echocardiography was performed in case 4. Operations were accomplished with the aid of temporary shunt in case 1, pulmonary-femoral artery bypass in case 2 and partial left heart bypass in cases 3 and 4. Prosthetic graft interposition was performed in cases 1, 3 and 4 and end-to-end aortic anastomosis was performed in case 2. There was no postoperative paraplegia in any patient. Early diagnosis and urgent surgical repair are important in treating blunt traumatic rupture of the thoracic aorta. Enhanced helical CT and transesophageal echocardiography are useful for the diagnosis of this type of injury.

ABSTRACT

Left ventricular myxoma is very rare and only 13 cases have been reported in Japan. A 14-year-old girl was admitted to a local hospital in November, 1983, with a sudden onset of right hemiparalysis. Two-dimensional echocardiograms and left ventricular angiograms revealed two left ventricular tumors. The patient was transferred to our hospital for the operation which was performed one month later. Two tumors originating from the apical interventricular septum were removed with resection of the septum through a left ventriculotomy. The tumors were 2.0×1.7cm in size and 1.9g in weight, 1.9×1.5cm in size and 1.1g in weight, respectively. The pathological diagnosis was myxoma. Her postoperative course was uneventful, and there has been no recurrence for 15 years after surgery. Japanese literature on the subject was reviewed.

ABSTRACT

Cardiac fibromas are rare tumors. A 12-year-old girl who had no cardiac symptoms was evaluated because of her abnormal ECG. Physical examination revealed a grade 1/6 systolic murmur. Routine laboratory examination results and the chest X-ray films were normal. The ECG showed a negative T wave at leads II, III, aVF and V<sub>3-4</sub>. Two-dimensional echocardiography demonstrated a tumor in the lower right ventricular free wall. Operation was performed on July 12, 1990. Sharp dissection was used to remove the tumor through right ventriculotomy. She had an uneventful postoperative course and is well 7 years later with no evidence of recurrence. Pathological findings including immunohistochemical studies revealed cardiac fibroma. The 22 reported cases of cardiac fibroma in Japan were reviewed.
