Between Jan. 1971 and Dec. 1974, 324 eyes which received Sr90 irradiation postoperatively at Severance Hospital and 819 eyes which received Sr90 irradiation postoperatively at a private eye clinic were observed. Among 324 eyes which received postoperatives Sr90 irradiation at Severance Hospital and 819 eyes which received postoperatives Sr90 irradiation at a private eye clinic, the incidences of recurrence were 3.4% and 3.3%.

Biliary cystadenoma is a rare biliary ductal neoplasm that usually arises in the liver and less frequently in the extrahepatic bile ducts. Clinical manifestations are non-specific; hence preoperative diagnosis depends heavily on imaging. Computed tomography, ultrasonography, angiography and cholangiogram are useful diagnostic procedures in biliary cystic tumor, but definite diagnosis depends on histologic diagnosis. Surgical resection often yields excellent results. Surgical procedures used to treat cystadenomas include: aspiration, drainage, marsupialization, and excision. If there is no evidence of metastasis, complete resection of these tumors is necessary for a complete cure. We experienced an 80-year-old man who complained of jaundice and RUQ pain. He was diagnosed as biliary mucinous cystadenoma, We confirmed our diagnosis by cholangioscopic biopsy, and performed endoscopic sphincterotomy(EST). So, we report this case and have reviewed the relevant literature as a part of our report for the subject case.

BACKGROUND: Significant increases in the prevalence of obesity have been observed among patients with peritoneal dialysis (PD). The impact of body mass index (BMI) on survival remains unknown in Korean PD patients. METHODS: Among data of 80,674 patients on PD acquired from the Insan Memorial ESRD Registry database for the years 1985 to 2014, 6,071 cases were analyzed. Subjects were classified by baseline BMI; < 21.19 kg/m² (quartile 1, n = 1,518), 21.19 to 23.18 kg/m² (quartile 2, reference; n = 1,453), 23.19 to 25.71 kg/m² (quartile 3, n = 1,583), and > 25.71 kg/m² (quartile 4, n = 1,517). RESULTS: Mean age was 65.8 years, and baseline BMI was 23.57 kg/m². Numbers of male and diabetic patients were 3,492 (57.5%) and 2,192 (36.1%), respectively. Among 6,071 cases, 2,229 (36.7%) all-cause deaths occurred. As a whole, Kaplan–Meier survival curves according to BMI quartiles was significantly different (P = 0.001). All-cause mortality was significantly higher in quartile 4 than in the reference (hazard ratio [HR] = 1.154, 95% confidence interval [CI], 1.025–1.300; P = 0.018). There was no statistical difference in all-cause mortality among BMI quartiles in diabetic patients on PD. In non-diabetic patients, all-cause mortality of quartiles 1 and 3 was not different from the reference, but the HR was 1.176 times higher in quartile 4 (95% CI, 1.024–1.350; P = 0.022). CONCLUSION: Baseline BMI > 25.71 kg/m² seems to be an important risk factor for all-cause mortality in Korean PD patients.
