Familial chylomicronemia syndrome related chronic pancreatitis: a single-center study

BACKGROUND: Hypertriglyceridemia induces acute recurrent pancreatitis, but its role in the etiology of chronic pancreatitis(CP) is controversial. This study aimed to evaluate the clinical laboratory and radiological findings of 7 patients with CP due to type 1 hyperlipidemia compared to CP patients with other or undefined etiological ***: We retrospectively analyzed the clinical, laboratory and radiological findings of 7 CP patients with type 1 hyper lipidemia compared to CP patients without hypertriglyceridemia These 7 patients had multiple episodes of acute pancreatitis and had features of CP on abdominal CT, endoscopic retrograde cholangiopancreatography and/or endoscopic ***: All CP patients were classified into two groups: a group with type 1 hyperlipidemia (n=7) and a group with other etiologies (n=58). The mean triglyceride level was 2323±894mg/dL in the first group. Age at the diagnosis of CP in the first group was significantly younger than that in the second group(16.5±5.9 vs 48.3±13.5, P<0.001). The number of episodes of acute pancreatitis in the first group was significantly higher than that in the second group (15.0±6.8 vs 4.0±4.6, P=0.011)The number of splenic vein thrombosis in the first group was significantly higher than that in the second group (4/7 vs 9/58P=0.025). Logistic regression analysis found that younger age was an independent predictor of CP due to hypertriglyceridemia(r=0.418, P=0.000).CONCLUSIONS: Type 1 hyperlipidemia appears to be an etiological factor even for a minority of patients with CP. It manifests at a younger age, and the course of the disease might be severe.

Significant cohort of non-alcoholic fatty liver disease with portal vein thrombosis in transplant waiting list

AIM: To characterize non-alcoholic fatty liver disease(NAFLD) presentation with esophageal varices. METHODS: We carried out a retrospective cohort study on 258 patients with esophageal varices at a single tertiary referral center. These patients underwent diagnosis of several liver diseases, including: NAFLDassociated cirrhosis, hepatitis B, hepatitis C, Wilson disease, autoimune liver diseases, and others. RESULTS: Of the 258 patients, 39% of patients exhibited esophageal varices due to NAFLD-associated cirrhosis. Of the 38(14.7%) patients developed hepatocellular carcinoma during follow-up, 52% were due to hepatitis B, 26% due to hepatitis C and 13.2% due to NAFLD. Of the 258 patients, 50.0% with NAFLD, 33.3% with hepatitis B, 26.3% with hepatitis C, and 58.3% with other diseases were alive at the end of the 5-year period with a significant difference according to the Kaplan-Meier log Rank test(P = 0.040). Portal vein thrombosis was detected in 47.5% of patients with NAFLD, in 29% of patients with hepatitis B, in 17% of patients with hepatitis C, and in 62% of patients with other related diseases(P < 0.0001). CONCLUSION: Our study showed a proportionally greater elevation in liver transplant candidacy in patients with NAFLD and portal vein thrombosis. Older patients were more prone to developing cirrhosis, hepatocellular carcinoma and a high mortality rate. However, younger patients exhibited more portal vein thrombosis and gastric varices.

Endoscopic ultrasound guided radiofrequency ablation,for pancreatic cystic neoplasms and neuroendocrine tumors

AIM: To outline the feasibility, safety, adverse events and early results of endoscopic ultrasound(EUS)-radiofrequency ablation(RFA) in pancreatic neoplasms using a novel probe. METHODS: This is a multi-center, pilot safety feasibility study. The intervention described was radiofrequency ablation(RF) which was applied with an innovative monopolar RF probe(1.2 mm Habib EUS-RFA catheter) placed through a 19 or 22 gauge fine needle aspiration(FNA) needle once FNA was performed in patients with a tumor in the head of the pancreas. The HabibTM EUSRFA is a 1 Fr wire(0.33 mm, 0.013") with a working length of 190 cm, which can be inserted through the biopsy channel of an echoendoscope. RF power is applied to the electrode at the end of the wire to coagulate tissue in the liver and ***: Eight patients [median age of 65(range 27-82) years; 7 female and 1 male] were recruited in a prospective multicenter trial. Six had a pancreatic cysticneoplasm(four a mucinous cyst, one had intraductal papillary mucinous neoplasm and one a microcystic adenoma) and two had a neuroendocrine tumors(NET) in the head of pancreas. The mean size of the cystic neoplasm and NET were 36.5 mm(SD ± 17.9 mm) and 27.5 mm(SD ± 17.7 mm) respectively. The EUSRFA was successfully completed in all cases. Among the 6 patients with a cystic neoplasm, post procedure imaging in 3-6 mo showed complete resolution of the cysts in 2 cases, whilst in three more there was a 48.4% reduction [mean pre RF 38.8 mm(SD ± 21.7 mm) vs mean post RF 20 mm(SD ± 17.1 mm)] in size. In regards to the NET patients, there was a change in vascularity and central necrosis after EUS-RFA. No major complications were observed within 48 h of the procedure. Two patients had mild abdominal pain that resolved within 3 d. CONCLUSION: EUS-RFA of pancreatic neoplasms with a novel monopolar RF probe was well tolerated in all cases. Our preliminary data suggest that the procedure is straightforward and safe. The response ranged from com
