Total Arch Replacement with Stented Elephant Trunk in DeBakey Type I Acute Aortic Dissection

A 67-year-old female patient was treated with conventional total arch replacement and insertion of a stented elephant trunk (SET) graft into the descending thoracic aorta for acute DeBakey type I aortic dissection at one time. She had been treated with right coronary artery stent insertion for acute myocardial infarct 4 days earlier, and at that time, she was diagnosed with acute DeBakey type I aortic dissection from the ascending aorta to the suprarenal artery based on trans-esophageal echocardiography and aorta computed tomography. Through a median sternotomy, we inserted the SET graft through the opened aorta to the descending aorta. We also performed anastomosis between the proximal stented graft and the distal aortic arch, and then performed total arch replacement. For acute DeBakey type I aortic dissection, we report total arch replacement with insertion of a SET graft as a combination of conventional surgery and the interventional technique.

Metastatic Small Cell Carcinoma of the Pancreas Originating from the Larynx / 대한내과학회지

Small cell carcinoma (SCC) is predominantly found in the lungs, and extrapulmonary small cell carcinoma (EPSCC) is a relatively rare disease, encompassing 2.5-4% of all SCCs. EPSCCs are commonly found in the esophagus, pancreas, skin, uterus, breasts, and prostate. SCC of the head and neck is aggressive and has a propensity for distant and regional spread. However, solitary metastasis to the pancreas is very rare. We report a case of laryngeal SCC with pancreatic metastasis in a 42-year-old man. The patient underwent resection of a primary SCC followed by a pylorus preserving pancreatoduodenectomy.

Follow-up Results of Endoscopic Mucosal Resection for Early Colorectal Cancer / 대한소화기학회지

BACKGROUND/AIMS: Recently colonoscopy and screening programs have led to the detection and removal of increasing numbers of early colorectal cancer (ECC), which can reduce its related mortality. We analysed the clinical, endoscopic, and histologic findings, as well as the follow-up data, to evaluate the effectiveness and the long-term results of endoscopic mucosal resection (EMR) for ECC. METHODS: We analysed, retrospectively, 94 lesions in 92 patients who underwent EMR for ECC from January 2002 to June 2009. RESULTS: The overage age of patients was 60 years old. The mean follow-up period was 22.1 months (6-80). En bloc resection rate was 64.9%. Submucosal invasion was found in 30 cases (31.9%). De novo cancer rate was 26.6% which had higher submucosal invasion rate (60%, p=0.003). The complete resection rate was 87.2%, and there was no recurrence of cancer during follow-up (p=0.000). Twelve incomplete resection cases had received further surgical treatments. No procedure-related mortality was found and no recurrent malignancy was found except 1 case. CONCLUSIONS: This study shows that EMR is an effective and safe treatment for ECC. En bloc resection provides precise histologic information and prevention of tumor recurrence.

A case of chronic neutrophilic leukemia / 대한내과학회지

Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative disorder characterized by clonal proliferation of mature neutrophils, hepatosplenomegaly, elevated leukocyte alkaline phosphatase score (ALP score) and a negative Philadelphia chromosome. To date, approximately 150 cases have been reported in the literature, including some cases presenting with a 'leukemic' state reflected by a neutrophilic reaction. The term 'true' CNL, recently introduced by Reilly, highlights the need for more experience with CNL cases to improve the diagnostic criteria. In Korea, about 10 cases have been reported in the literature and some of those cases did not meet the WHO diagnostic criteria for CNL. We present a typical case of CNL in a 66-year-old man who complained of general weakness and weight loss. On admission, the white blood cell count from the peripheral blood was 175,600/L with 80% segmented neutrophils. The cytogenic study was negative for the Philadelphia chromosome and had a normal karyotype.
