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.

BACKGROUND/AIMS: The optimal management of bleeding peptic ulcer with adherent clot remains controversial. The purpose of this study was to compare clinical outcome between endoscopic therapy and medical therapy. We also evaluated the risk factors of rebleeding in Forrest type IIB peptic ulcer. METHODS: Upper gastrointestinal (UGI) bleeding registry data from 8 hospitals in Korea between February 2011 and December 2013 were reviewed and categorized according to the Forrest classification. Patients with acute UGI bleeding from peptic ulcer with adherent clots were enrolled. RESULTS: Among a total of 1,101 patients diagnosed with peptic ulcer bleeding, 126 bleedings (11.4%) were classified as Forrest type IIB. Of the 126 patients with adherent clots, 84 (66.7%) received endoscopic therapy and 42 (33.3%) were managed with medical therapy alone. The baseline characteristics of patients in two groups were similar except for higher Glasgow Blatchford Score and pre-endoscopic Rockall score in medical therapy group. Bleeding related mortality (1.2% vs. 10%; p=0.018) and all cause mortality (3.7% vs. 20.0%; p=0.005) were significantly lower in the endoscopic therapy group. However, there was no difference between endoscopic therapy and medical therapy regarding rebleeding (7.1% vs. 9.5%; p=0.641). In multivariate analysis, independent risk factors of rebleeding were previous medication with aspirin and/or NSAID (OR, 13.1; p=0.025). CONCLUSIONS: In patients with Forrest type IIB peptic ulcer bleeding, endoscopic therapy was associated with a significant reduction in bleeding related mortality and all cause mortality compared with medical therapy alone. Important risk factor of rebleeding was use of aspirin and/or NSAID.

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy. The treatment of pulmonary artery embolism includes remittance of pulmonary arterial hypertension, anticoagulation, thrombolysis, operative thrombectomy, interventional therapy and extracorporeal membrane oxygenation (ECMO). Hemorrhage is a rarely occurred but relatively serious complication after bariatric surgery. The primary cause of anastomotic bleeding after laparoscopic gastric bypass is incomplete hemostasis or weak laparoscopic repair. The common bleeding site in laparoscopic sleeve gastrectomy is gastric stump and close to partes pylorica, and the bleeding may be induced by malformation and weak repair technique. Patients with hemodynamic instability caused by active bleeding or excessive bleeding should timely received surgical treatment. Anastomotic fistula in gastric bypass can be divided into gastrointestinal anastomotic fistula and jejunum-jejunum anastomotic fistula. The treatment of postoperative anastomotic fistula should vary with each individual, and conservative treatment or operative treatment should be adopted. Anastomotic stenosis is mainly related to the operative techniques. Stenosis after sleeve gastrectomy often occurs in gastric angle, and the treatment methods include balloon dilatation and stent implantation, and surgical treatment should be performed when necessary. Marginal ulcer after gastric bypass is a kind of peptic ulcer occurring close to small intestine mucosa in the junction point of stomach and jejunum. Ulcer will also occur in the vestige stomach after laparoscopic sleeve gastrectomy, and the occurrence site locates mostly in the gastric antrum incisal margin. Preoperative anti-HP (helicobacter pylorus) therapy and postoperative continuous administration of proton pump inhibitor (PPI) for six months is the main means to prevent and treat marginal ulcer. For patients on whom conservative treatment is invalid, endoscopic repair or surgical repair should be considered. Different surgical procedures will generate different related operative complications. Fully understanding and effectively dealing with the complications of various surgical procedures through multidisciplinary cooperation is a guarantee for successful operation.

BACKGROUND/AIMS: Increased incidence of coronary artery disease has led to the increased use of dual antiplatelet therapy composed of aspirin and clopidogrel. We investigated the incidence of gastrointestinal complications in patients who received single or dual antiplatelet therapy and analyzed their clinical characteristics in order to predict the prognostic factors. METHODS: Between January 2009 and December 2011, we retrospectively reviewed the medical records of patients who underwent coronary angiography at Chung-Ang University Hospital (Seoul, Korea). One hundred and ninety-four patients were classified into two groups: aspirin alone group and dual antiplatelet group. Clinical characteristics, past medical history, and presence of peptic ulcer were analyzed. RESULTS: During the follow-up period, 11 patients had duodenal ulcer; the event rate was 2.02% in the aspirin alone group and 9.47% in the dual antiplatelet group (hazard ratio [HR] 5.24, 95% CI 1.03-26.55, p<0.05). There was no significant difference in the rate of significant upper gastrointestinal bleeding: 0% vs. 4.2% (p=0.78). In patients who received proton pump inhibitor (PPI), 24 patients had gastric ulcer; the event rate was significantly different between the two groups: 4.87% vs. 22.98% (HR 3.40, 95% CI 1.02-11.27, p<0.05). CONCLUSIONS: Dual antiplatelet groups had a higher incidence of duodenal ulcers without significant bleeding compared with the aspirin alone group. In patients who received PPI, the dual antiplatelet therapy group had a higher incidence of gastric ulcers without significant bleeding compared with the aspirin alone group. Therefore, physicians must pay attention to high risk groups who receive dual antiplatelet therapy and aggressive diagnostic endoscopy should also be considered.
