1.Natural History and Overlap of Functional Gastrointestinal Disorders.
The Korean Journal of Gastroenterology 2012;60(6):345-348
Functional gastrointestinal (GI) disorders are common in the general population. Based on the Rome III classification, these disorders are mutually exclusive disorders keeping the homogeneity of each functional GI disorder in research area. In contrast, many population and clinical studies have reported a considerably high rate of overlap between functional GI disorders. The overlap of functional GI disorders over other intestinal diseases might simply occur by chance due to a highly prevalent disorder. Moreover, functional GI disorders is considered a chronic stable disorder that may wax and wane for several years. However, a recent study about the natural history of functional GI disorders showed substantial transition among functional GI disorders over time. The natural history of functional GI disorders with overlapping other functional GI disorders are still in infancy and better understanding of these will be important in determining the efficacy of future therapeutic interventions.

This study sought to determine the value of portal venography with 64-slice MDCT in the evaluation of compensatory circulation resulting from decompensated posthepatitic cirrhosis (PHC), and in the clarification of its anatomic distribution. Thirty-six patients with clinically confirmed compensatory circulations resulting from PHC were enrolled in this study. They underwent thoracicoabdominal triphasic enhancement CT scans with 64-slice MDCT. The data of the portal venous phase acquired were used for obtaining CT-MIP (maximum intensity projection) images of portosystematic collaterals such as gastric fundic and esophageal varices, paraumbilical veins, spleno-renal shunts, and their inflowing and outflowing vessels. On CT-MIP portography, gastric fundic varices were shown in 35 cases (97%) and esophageal varices in 30 cases (83%). The left gastric vein was the common inflowing vessel of the varices in 34 cases (94%); it was mainly originated from splenic vein in 24 cases (67%). With regard to the outflowing vessels, they were commonly azygos vein in 30 cases (83%). As for paraumbilical veins in 7 cases (19%), the inflowing vessel was the left branch of portal vein, and the outflowing vesse was the superficial epigastric vein. Cavernous transformation of the portal vein was seen in 5 cases (14%) and cavernous transformation of splenic vein was seen in 16 cases (44%). CT-MIP venography with 64-row MDCT could be considered as an effective and noninvasive method for detecting the compensatory circulation resulting from decompensated PHC.

OBJECTIVETo investigate the clinical epidemiology change trend of upper gastrointestinal bleeding (UGIB) over the past 15 years.
METHODSConsecutive patients who was diagnosed as continuous UGIB in the endoscopy center of The First Affiliated Hospital of Sun-Yat University during the period from 1 January 1997 to 31 December 1998 and the period from 1 January 2012 to 31 December 2013 were enrolled in this study. Their gender, age, etiology, ulcer classification, endoscopic treatment and hospitalization mortality were compared between two periods.
RESULTSIn periods from 1997 to 1998 and 2012 to 2013, the detection rate of UGIB was 9.99%(928/9 287) and 4.49%(1 092/24 318)(χ=360.089, P=0.000); the percentage of male patients was 73.28%(680/928) and 72.44% (791/1 092) (χ=0.179, P=0.672), and the onset age was (47.3±16.4) years and (51.4±18.2) years (t=9.214, P=0.002) respectively. From 1997 to 1998, the first etiology of UGIB was peptic ulcer bleeding, accounting for 65.2%(605/928)[duodenal ulcer 47.8%(444/928), gastric ulcer 8.3%(77/928), stomal ulcer 2.3%(21/928), compound ulcer 6.8%(63/928)],the second was cancer bleeding(7.0%,65/928), and the third was esophageal and gastric varices bleeding (6.4%,59/928). From 2012 to 2013, peptic ulcer still was the first cause of UGIB, but the ratio obviously decreased to 52.7%(575/1092)(χ=32.467, P=0.000)[duodenal ulcer 31.9%(348/1092), gastric ulcer 9.4%(103/1092), stomal ulcer 2.8%(30/1092), compound ulcer 8.6%(94/1092)]. The decreased ratio of duodenal ulcer bleeding was the main reason (χ=53.724, P=0.000). Esophageal and gastric varices bleeding became the second cause (15.1%,165/1 092, χ=38.976, P=0.000), and cancer was the third cause (9.2%,101/1 092, χ=3.352, P=0.067). The largest increasing amplitude of the onset age was peptic ulcer bleeding [(46.2±16.7) years vs. (51.9±18.9) years, t=-5.548, P=0.000), and the greatest contribution to the amplitude was duodenal ulcer bleeding [(43.4±15.9) years vs. (48.4±19.4) years, t=-3.935, P=0.000], while the onset age of esophageal and gastric varices bleeding [(49.8±14.1) years vs. (48.8±13.9) years, t=0.458, P=0.648] and cancer [(58.4±13.4) years vs. (58.9±16.7) years, t=-0.196, P=0.845] did not change significantly. Compared with the period from 1997 to 1998, the detection rate of high risk peptic ulcer rebleeding (Forrest stage I(a, I(b, II(a and II(b) increased (χ=39.958, P=0.000) in the period from 2012 to 2013. From 1997 to 1998, 54 patients underwent endoscopic treatment, and the achievement ratio of hemostasis was 79.6% (43/54). From 2012 to 2013, 261 patients underwent endoscopic treatment and the achievement ratio of hemostasis was 96.9%(253/261), which was significantly higher (χ=23.287, P=0.000). Compared to the period from 1997 to 1998, more patients with variceal bleeding or non-variceal bleeding received endoscopic treatment in time (39.0% vs. 70.3%, χ=51.930, P=0.000; 3.6% vs. 15.6%, χ=62.292, P=0.000, respectively), and higher ratio of patients staging Forrest stage I(a to II(b also received endoscopic treatment in the period from 2012 to 2013 [27.4%(26/95) vs. 68.5%(111/162), χ=40.739, P=0.000]. More qualified endoscopic hemostatic techniques were used, containing thermocoagulation (0 vs. 15.2%, χ=79.518, P=0.000), hemostatic clip (0 vs. 55.9%, χ=20.879, P=0.000), hemostatic clip combined with thermocoagulation (4.3% vs. 16.4%, χ=5.154, P=0.023), while less single injection was used (87.1% vs. 6.2%, χ=10.420, P=0.001), and single spraying for hemostasis was completely abandoned in the period from 2012 to 2013. The ratio of inpatients undergoing reoperation decreased obviously in the period from 2012 to 2013 [9.3%(86/928) vs. 6.0%(65/1092), χ=7.970, P=0.005], while no significant difference was found in mortality during hospitalization between two periods.
CONCLUSIONCompared with the period from 1997 to1998, the mean onset age of UGIB increased, and the ratio of peptic ulcer bleeding decreased due to the reduction of duodenal ulcer bleeding, the detection rate of high risk peptic ulcer rebleeding increased, the cure rate of endoscopic treatment for UGIB increased, more reasonable and immediate hemostatic methods were used, but overall mortality did not change obviously in the period from 2012 to 2013.

OBJECTIVETo evaluate the effect of portal hypertension on prognosis in patients with decompensated liver cirrhosis.
METHODSThe clinical data of decompensated cirrhosis patients in our hospital, between 2003 and 2006, were retrospected and followed up. Model for end-stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP) classification was calculated using the standard formula. Kaplan-Meier survival analysis was used to compare the mortality in subgroups ranked by the syndromes. Cox proportional hazards regression was used to evaluate the effect of the syndromes on prognosis.
RESULTSA cohort of 322 patients was admitted in this study at the end of the follow-up. The mortality of variceal bleeding, hepatic encephalopathy, a large volume ascites, spontaneous bacterial peritonitis, the type I and type II hepatorenal syndrome was 45.9%, 79.4%, 66.7%, 100%, 100% and 84.6% respectively. On the whole, the occurrence of all the syndromes was correlated with CTP classification and MELD score. Kaplan-Meier survival analysis showed that all of these syndromes, except for low to medium volume of ascites, significantly affected the survival rate (P<0.01). In Cox regression analysis, all the syndromes were the independent predictors of prognosis, the regression coefficient values of hepatic encephalopathy, spontaneous bacterial peritonitis, type I and type II hepatorenal syndrome, variceal bleeding and ascites were 0.973, 0.928, 0.935, 0.866, 0.464 and 0.369 respectively.
CONCLUSIONSThe portal hypertensive syndromes have significant effect on the prognosis of the patients with decompensated cirrhosis, hepatic encephalopathy is the worst one.
