BACKGROUND: The eating habits of Jeju Island natives are quite different from those of the mainland people because of geographic isolation. Diet is a main factor affecting gallstone disease. We investigated the prevalence of gallstone disease in both Jeju Island natives and migrants and studied the risk factors affecting gallstone disease in the Jeju Island people. METHODS: A total of 20,763 subjects who underwent medical checkups at the Health Promotion Center of Jeju National University Hospital in Korea from January 2003 to December 2015 were enrolled in the study. Ultrasonography was used to determine the presence of gallbladder stones. Body mass index and biochemical parameters, including liver function test results, lipid profiles, and fasting blood glucose levels, were verified, and data on age, birthplace, and sex were collected from medical records. Univariate and multivariate analyses were performed to identify risk factors affecting gallstone disease. RESULTS: The prevalence of gallstone disease in the Jeju Island people was 4.0%: Jeju Island natives, 3.8% and migrants, 4.4% (P=0.047). After multivariate logistic regression analysis, the independent risk factors were older age, Jeju migrants, higher fasting blood glucose and alanine aminotransferase levels, and lower high-density lipoprotein cholesterol levels. CONCLUSION: The prevalence of gallstone disease was significantly lower in natives than in migrants from Jeju Island. Older age, Jeju migrants, higher fasting blood glucose and alanine aminotransferase levels, and lower high-density lipoprotein cholesterol levels contributed to gallstone disease prevalence in the Jeju Island people.

We experienced a case of a gallbladder carcinoma detected incidentally by elevated serum alpha- fetoprotein. The patient had a symptom of mild intermittent indigestion, and a routine medical examination revealed elevation of serum alpha-fetoprotein. A mass, 4 cm 3 cm, was located in the gallbladder and it had not infiltrated the liver. The serum level of alpha-fetoprotein decreased after a cholecystectomy. The gallbladder mass was an adenocarcinoma of hepatoid differentiation. Cytoplasms of the tumor cells had positive reactivity to immunohistochemical staining of alpha-fetoprotein. In the course of postoperative follow up, the serum alpha-fetoprotein level increased continuously, and abdominal CT scanning proved multiple intrahepatic metastases.

PURPOSE: Gastrin is a candidate for the growth regulatory factors of the pancreas and may solve the problem of pancreatic atrophy after partial pancreatectomy. The purpose of this study was to evaluate the effect of endogenous gastrin on the normal growth and regeneration of the pancreas (after partial pancreatectomy) in rat. METHODS: Sixty Sprague-Dawley rats (200-230 g) were divided into 6 groups. Group (G)-I and II received sham operation (splenectomy only), and G-III, IV, V, VI received both 66% partial pancreatectomy (PPx) and splenectomy. Endogenous hypergastrinemia was induced in G-II, IV, VI by stomach gavage of 30 mg/kg.day of Lansoprozole (LSP) for 3 weeks. In G-V and VI, L365,260 (ML lab, UK) was given continuously in a dose of 50 microgram/kg/hour intraperitoneally using osmotic mini pump. The rats were sacrificed 3 weeks later, and serum gastrin, the weight and the amount of DNA, RNA, and protein in the remnant pancreas or corresponding part were checked. RESULTS: Serum gastrin concentration was 3-4 times higher in the groups received LSP. LSP stimulated growth of the pancreas (G-I: 11921 vs. G-II: 14220 mg/100 g body weight, p=0.047), and the effect was even greater in partial pancreatectomy groups (G-III: 14616 vs. G-IV: 17318 mg/100 g body weight, p=0.007). Total DNA, RNA, and protein amount in the remnant pancreas showed the same trends as the pancreas weight. The effect of LSP was totally abolished by L365,260 (G-V: 13517 vs. G-VI: 14313 mg/100 g body weight, p>0.047). CONCLUSION: Endogenous gastrin has a stimulatory effect on normal growth, and a much stronger effect on the regeneration of the rat pancreas after partial pancreatectomy. Further investigations including clinical trial should be needed.

PURPOSE: A major hepatobiliary resection (MHBR), liver resection of more than one lobe, has been recommended by some surgeons for advanced carcinomas (Ca) of the gallbladder (GB) and the hilar bile duct (HBD). However, high operative mortality and morbidity have been reported and its survival benefit has not been clearly documented. METHODS: We report the results of MHBR for such tumors to determine the safety and the effectiveness of this operation, which has been performed for GB Ca invading the right hepatic pedicle or liver bed by 2 cm or more and for HBD Ca of Bismuth type III or IV. The cases of fifty consecutive cases who received MHBR for GB Ca (n=11) or HBD Ca (n=39) during a 5 year-period were reviewed. RESULTS: Thirty right-sided and 20 left-sided hepatectomies were performed. There was no operative or hospital death. Minor and major complications developed in 64% of the cases. All the complications improved with conservative management, except two in which re operations were required, one due to portal vein thrombosis and the other to bleeding of the retro peritoneal dissection site. No specific factors were associated with the high complication rate. The long-term outcome of HBD Ca was better than that of GB Ca. In HBD Ca, differentiated cancer and less transfusion were associated with a better prognosis. CONCLUSION: MHBR was conducted with acceptable morbidity and no mortality. In terms of the long-term outcome, MHBR is recommended for HBD Ca whereas it should be considered more carefully for GB Ca.

Retrohepatic caval injuries are a difficult problem to surgeons as its mortality approaching 50~80%. Several bypass techniques was advocated to reduce operative bleeding and to improve the prognosis of the traumatized patients. We successfully managed a case of retro hepatic caval injury using venovenous bypass and total hepatic vascular isolation. A 28 year old female patients was admitted to Cheju Medical Center injured in a traffic accident. At exploration, a retrohepatic caval injury was suspected. So patient was emergently transferred to Seoul National University Hospital, after gauze packing. On arrival, vital signs were stable. Reexploration was undertaken. There was gush out of blood from retrohepatic space. After clamping suprahepatic and infrahepatic vena cava, venovenous bypass was introduced to left axillary vein and left femoral vein using Biomedicus pump. Systemic heparinization was not used. Avulsion between vena cava and common trunk of left and middle hepatic veins was repaired and left hepatectomy was done. Gauze packing was done due to ongoing oozing by coagulopathy from massive transfusion. Total venovenous bypass time was 30 min. On 10th operative day, reexploration was undertaken to assure hemostasis and to remove packed gauze. On 54th postoperative day patient discharged without any morbidity.

BACKGROUNDS: A mucin-producing bile duct tumor is a rare disease causing diffuse bile duct dilatation and intermittent obstructive jaundice due to mucin accumulation in the bile duct. A massive amount of mucin in the dilated bile duct is confirmed during surgery, endoscopic drainage, or percutaneous drainage. These tumors are usually slow-growing, well-differentiated papillary adenocarcinomas that shows intraductal spreading or an intraductal papillary growth pattern. PURPOSE: The purpose of this study was to evaluate the clinical, radiological, and histopathological characteristics of mucin-producing bile duct tumors. METHODS: We treated 10 patients with mucin-producing bile duct tumors during the recent 5 years. Clinical features were reviewed, including symptoms and signs, radiologic characteristics, operative findings, and pathological characteristics. RESULTS: The main clinical symptoms were recurrent abdominal pain, fever, chill, and intermittent jaundice. The characteristic radiologic findings were marked dilatation of the bile ducts distal to the tumors on computed tomography (CT) and ultrasonography and multiple, large, amorphous filling defects on cholangiography. In three cases, percutaneous transhepatic cholangioscopy (PTCS) was useful not only in making a diagnosis but also in delineating the extents of the tumors. In seven of ten cases involved (70%), the tumors were located mainly in the left intrahepatic duct. Pathologically, six (60%) cases were differentiated papillary adenocarcinoma. CONCLUSIONS: A mucin-producing bile duct tumor should be suspected if the patient has diffuse bile duct dilatation without definite evidence of stones, and it can be confirmed by a large amount of mucin secretion. If this type of tumor is suspected, careful preoperative evaluation, including PTCS, should be considered for making an accurate preoperative diagnosis and for determining the extent of the tumor.

BACKGROUND: Perioperative morbidity and mortality following a pancreaticoduodenectomy have decreased markedly over the last two decades, so many surgical centers advocate expanding the indications for a pancreaticoduodenectomy to include benign lesions other than periampullary malignancies. METHODS: Between 1990 and 1997, 22 patients underwent a pancreaticoduodenectomy (9 classical Whipple's operations, 10 pylorus-preserving pancreaticoduodenectomies and 3 duodenum preserving resection of the head of the pancreas) for benign disease from among a total of 306 patients receiving pancreaticoduodenectomy. The postoperative morbidity and mortality were analyzed retrospectively. RESULTS: The sites of the lesions were the pancreatic head (n=12), the common bile duct (n=5), the duodenum (n=3) and the ampulla of Vater (n=2). The most frequent indication for pancreaticoduodenectomy was a suspicion of malignancy. There was no immediate postoperative mortality, and perioperative complications occurred in 50% of the patients (11/22 patients). During the follow-up period (mean follow-up: 23.8 month), there were no complications or mortalities related to either disease or the operation. CONCLUSIONS: This study suggests that a pancreaticoduodenectomy should be recommended for periampullary benign disease if malignancy cannot be excluded or if the lesion cannot be removed without the procedure. However, perioperative morbidity and mortality are still higher for a pancreaticoduodenectomy than for other procedures, so patient selection and perioperative management should be careful, also, a more conservative procedure than the classical Whipple's operation should be considered for benign lesions, if possible, for better quality of life.

Acute onset of shock presented in a 23 years old male patient due to gastrointestinal bleeding. He had been in a car crash 49 days before presentation. On initial presentation, a small amount of intraperitoneal hemorrhage had been seen on a CT scan. An emergency selective superior mesenteric artery (SMA) arteriography revealed a pseudoaneurysm in the branch of SMA, but successive embolization of the terminal branch controlled the bleeding. It is hard to initially diagnose an aneurysm as the cause of spontaneous gastrointestinal bleeding in a patient that has suffered an abdominal trauma, so it poses a therapeutic challenge. Recognition of an aneurysm, and its early diagnosis based on the patient's past history, and its adoption as a judicious diagnostic tool are essential in the management of such patients.

We report a very rare case of colonic varix with massive bleeding. A 43-year-old male patient was transferred to our hospital for hematochezia. The patient had a history of chronic liver disease associated with alcohol use. The initial blood pressure was 93/73 mmHg, and the hemoglobin level was 8.4 g/dL. Severe hepatomegaly and periportal fatty infiltration were seen on abdominal computed tomography. Markedly ectatic veins protruded from the luminal side of the proximal ascending colon and drained to the dilated ileocecal and retroperitoneal veins. Emergent colonoscopy failed because of continuous hematochezia and hypovolemic shock, despite massive transfusion. Markedly dilated colonic varices were noticed around the ileocecal and ascending colon on superior mesenteric arteriography. An emergent right hemicolectomy was performed. The presumed bleeding focus was a protruding varix with a red clot on the top of a denuded vein on the anteromedial wall of the proximal ascending colon.
