Kawasaki disease (KD) is a systemic vasculitis associated with various clinical manifestations and complications, such as gastrointestinal abnormalities. We report a 3-year-old boy who presented with hematemesis and diffuse gastroduodenal ulcerations complicating KD. He received standard medical therapy for the disease and gastric ulcer, which showed effect after a few days. Although rare, peptic ulcers should be considered a complication of KD to ensure early diagnosis and treatment as it may cause severe morbidity.

The eradication of Helicobacter pylori and the widespread use of effective antisecretory therapies, including proton pump inhibitors, have improved the management of peptic ulcer disease. However, in some patients, peptic ulcer disease is refractory to 8 to 12 weeks of standard antisecretory drug treatment. For refractory peptic ulcer disease, further evaluation of the risk factors and causes of refractory peptic ulcer disease, including patient risk factors and noncompliance (smoking, nonsteroidal anti-inflammatory drug use, and noncompliance with medical treatment), persistent H. pylori infection, and non-H. pylori-related factors (giant ulcer, gastrinoma, infections other than H. pylori, and malignancy), is essential. The treatment should focus on the cause of the refractory peptic ulcer disease, avoiding smoking and nonsteroidal anti-inflammatory drug, the treatment of persistent H. pylori, use of high-dose proton pump inhibitors, or surgical excision of gastrinomas. Surgery should be considered in patients who are at high risk for complications and recurrent peptic ulcer disease despite medical treatment. In this review, I describe the diagnosis and treatment of refractory peptic ulcer disease.

PURPOSE: This study was performed to assess the clinical usefulness of transabdominal ultrasonography (TUS) in detecting peptic ulcer disease (PUD) in children. METHODS: Twenty-four patients (19 boys, 5 girls; mean age, 10.6±4.5 years [range, 3.0–17.9 years]) who were admitted to the hospital for acute abdomen or gastrointestinal bleeding and diagnosed with PUD by endoscopy and who underwent TUS were included. Clinical data were retrospectively collected by reviewing patient medical records. Gastric ulcer (GU) was suspected when the gastric wall exceeded 8 mm in thickness and had lost its five-layer structure on TUS. Duodenal ulcer (DU) was suspected if the duodenal wall thickness exceeded 5 mm. RESULTS: Sensitivity of TUS in diagnosing PUD was 66.7% for GU and 38.9% for DU. Mean age and body weight of the 11 patients suspected with PUD on TUS were 10.9±4.4 years and 38.1±17.2 kg, respectively. For 13 patients without suspected PUD, they were 12.1±4.1 years and 39.6±17.0 kg, respectively. There was a significant difference in height, weight, and body mass index between patients who were suspected to have PUD and those who were not suspected on TUS (p=0.014, 0.008, and 0.005, respectively). A significant difference in the sensitivity of TUS in diagnosing PUD was found between patients under 30 kg and those over 30 kg (88.9% and 20.0%, respectively; p=0.003). CONCLUSION: TUS investigation of the stomach and duodenum is an efficient method for PUD detection in children with low body weight. TUS can be used in preliminary diagnostic work-up before further invasive tests.

Cholecystocolic fistula (CCF) is a rare and late complication of gallbladder disease. The cause of CCF is known to be peptic ulcer, gallbladder disease, malignant tumor, trauma, and postoperative complications. The proper treatment method is to perform cholecystectomy and to identify and alleviate the CCF. However, cholecystectomy is not always possible owing to technical difficulties and disease severity. CCF is difficult to diagnose preoperatively, and CCF operation without an accurate preoperative diagnosis can lead to a more complicated surgery and cause surgeons to face more difficult situations or to endanger patients' lives. We report a case of asymptomatic CCF successfully treated with laparoscopic surgery after accurate diagnosis before surgery.

BACKGROUND/AIMS: Gastrointestinal (GI) bleeding is a life-threatening complication in critically ill patients. The aim of this study was to determine the efficacy of bedside endoscopy in an intensive care unit (ICU) setting, and to compare the outcomes of early endoscopy (within 24 hours of detecting GI bleeding) with late endoscopy (after 24 hours). METHODS: We retrospectively reviewed the medical records of patients who underwent bedside endoscopy for nonvariceal upper GI bleeding and lower GI bleeding that occurred after ICU admission at Seoul National University Hospital from January 2010 to May 2015. RESULTS: Two hundred and fifty-three patients underwent bedside esophagogastroduodenoscopy (EGD) for upper GI bleeding (early, 187; late, 66) and 69 underwent bedside colonoscopy (CS) for lower GI bleeding (early, 36; late, 33). Common endoscopic findings were peptic ulcer, and acute gastric mucosal lesion in the EGD group, as well as ischemic colitis and acute hemorrhagic rectal ulcers in the CS group. Early EGD significantly increased the rate of finding the bleeding focus (82% vs. 73%, p = 0.003) and endoscopic hemostasis (32% vs. 12%, p = 0.002) compared with late EGD. However, early CS significantly decreased the rate of identifying the bleeding focus (58% vs. 82%, p = 0.008) and hemostasis (19% vs. 49%, p = 0.011) compared with late CS due to its higher rate of poor bowel preparation and blood interference (38.9% vs. 6.1%, p = 0.035). CONCLUSIONS: Early EGD may be effective for diagnosis and hemostatic treatment in ICU patients with GI bleeding. However, early CS should be carefully performed after adequate bowel preparation.

Helicobacter pylori plays an important role in the pathogenesis of chronic gastritis, peptic ulcer disease, gastric cancer, and gastric mucosa-associated lymphoid tissue lymphoma. In Korea, the guidelines for the diagnosis and treatment of H. pylori infection in adults were revised in 2013. The European Helicobacter and Microbiota Study Group and Consensus panel released the fifth edition of the Maastricht Consensus Report for the management of H. pylori infection in 2015, and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition released the updated joint guidelines for children and adolescents in 2016. Considering these recommendations and recent progress in our research and that of other research teams, this study aimed to discuss the diagnostic strategies for H. pylori infection in children and adolescents.

Gastric outlet obstruction (GOO) is a disease that causes pyloric canal or duodenal atresia by various etiologies. It is mainly caused by malignancy or peptic ulcer and rarely caused by corrosive injury, gastric polyp, pyloric stenosis, bezoar, or biliary stone. We report a rare case of GOO due to unreported etiology. A 74-year-old male patient with medical history of hypertension, diabetes mellitus, and stroke came to the emergency medical center with a chief complaint of acute stomachache. On abdominal computed tomography, it was diagnosed as GOO due to gall bladder distension from acute cholecystitis. During conservative treatment and antibiotics administration, gastrofibroscopy and magnetic resonance cholangiopancreatography was performed to determine other etiologies; however, the final diagnosis was made as acute cholecystitis. After laparoscopic cholecystectomy, he was discharged without specific complications. On a pathology examination postoperation, there was no specific diagnosis, except for acute cholecystitis. Gastric outlet obstruction is caused by various etiologies, with the course of treatment being dependent on the specific etiology. We report a rare case of GOO caused by gall bladder distension due to acute cholecystitis. Various etiologies should be considered carefully to include even the rare etiologies for choosing the correct treatment.

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential method for diagnosis and treatment of various pancreatobiliary diseases and endoscopic sphincterotomy (EST) is the gateway to complete ERCP. Although techniques and instruments for EST have improved, bleeding is still the most common complication. Treatment of immediate post-EST bleeding is important because blood can interfere with subsequent procedures. Additionally, endoscopists should be cautious about delayed bleeding may cause hemobilia, cholangitis, and hemodynamic shock. Most cases of post-EST bleedings will stop spontaneously, however, endoscopic management is necessary in case of clinically significant and persistent bleeding. Various endoscopic methods including epinephrine or fibrin glue injection, electrocoagulation, hemoclipping and band ligation et al can be used through a sideviewing or forward-viewing endoscope similar to those used in hemostasis of peptic ulcer bleeding. Endoscopists who perform ERCP should use various methods of endoscopic hemostasis strategically.

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.
