ABSTRACT

With an aging population, the number of patients with difficulty in swallowing due to medical conditions is gradually increasing. In such cases, enteral nutrition is administered through a temporary nasogastric tube. However, the long-term use of a nasogastric tube leads to various complications and a decreased quality of life. Percutaneous endoscopic gastrostomy (PEG) is the percutaneous place­ment of a tube into the stomach that is aided endoscopically and may be an alternative to a nasogastric tube when enteral nutritional is required for four weeks or more. This paper is the first Korean clinical guideline for PEG developed jointly by the Korean College of Helicobacter and Upper Gastrointestinal Research and led by the Korean Society of Gastrointestinal Endoscopy. These guidelines aimed to provide physicians, including endoscopists, with the indications, use of prophylactic antibiotics, timing of enteric nutrition, tube placement methods, complications, replacement, and tubes removal for PEG based on the currently available clinical evidence.

ABSTRACT

Foreign body ingestion is commonly seen in children. However, occasionally it may also be seen among adults and is often associated with intellectual disability, psychiatric disorders, and alcoholism. Ingestion of a magnetic foreign body may cause complications such as gastrointestinal tract perforation, wherein emergency endoscopic removal of the foreign body is generally required. Here, we report a rare case of a 59-year-old male with an intellectual disability and psychiatric disorder in whom metallic objects in the stomach cavity were accidentally discovered during abdominal CT. Esophagogastroduodenoscopy revealed several metallic objects attached to two magnets, which had been ingested several years before and had remained in the stomach cavity. The magnets and metallic objects were safely removed endoscopically using rat-tooth forceps without complications.

ABSTRACT

Background/Aims@#To date, there is no prospective study that specifically investigated the efficacy of infliximab in intestinal Behçet’s disease (BD). This study evaluated the efficacy of infliximab in patients with moderate-to-severe active intestinal BD that are refractory to conventional therapies. @*Methods@#This phase 3, interventional, open-label, single-arm study evaluated clinical outcomes of infliximab treatment in patients with moderate-to-severe intestinal BD. The coprimary endpoints were clinical response, decrease in disease activity index for intestinal BD (DAIBD) score ≥20 from weeks 0 to 8 for the induction therapy and week 32 for the maintenance therapy. @*Results@#A total of 33 patients entered the induction therapy and were treated with infliximab 5 mg/kg intravenously at weeks 0, 2, and 6. The mean DAIBD score changed from 90.8±40.1 at week 0 to 40.3±36.4 at week 8, with a significant mean change of 50.5±36.4 (95% confidence interval, 37.5 to 63.4; p<0.001). Thirty-one (93.9%) continued to receive 5 mg/kg infliximab every 8 weeks during the maintenance therapy. The mean change in the DAIBD score after the maintenance therapy was statistically significant (61.5±38.5; 95% confidence interval, 46.0 to 77.1; p<0.001, from weeks 0 to 32). The proportion of patients who maintained a clinical response was 92.3% at week 32. No severe adverse reactions occurred during the induction and maintenance therapies. @*Conclusions@#This study provided evidence that infliximab 5 mg/kg induction and maintenance therapies are efficacious and well-tolerated in patients with moderate-to-severe active intestinal BD.

ABSTRACT

Patients with inflammatory bowel disease (IBD) are at risk for extraintestinal manifestations (EIM) over the course of their disease. As EIMs can involve nearly every organ, and strongly influence the quality of life, early recognition and adequate treatment are necessary to prevent severe morbidity and mortality in affected patients. Pyoderma gangrenosum is a highly severe and debilitating skin condition that occurs in 1% to 10% of ulcerative colitis (UC) patients. Thromboembolic events are also serious EIMs and usually present as deep vein thromboses in the legs or as pulmonary embolisms. A 19-year-old woman presented with bloody diarrhea lasting for 3 months and deep ulceration on the right foot. She was diagnosed with UC. The patient's skin lesions did not improve with intravenous corticosteroids and oral mesalazine. After she was started on infliximab, we observed rapid resolution of the skin lesions. She continued to complain of mild dyspnea while in the hospital. Computed tomography performed using the thromboembolism protocol revealed pulmonary thromboembolism and deep venous thrombosis. The patient underwent anticoagulant therapy with low-molecular-weight heparin, and her dyspnea gradually improved. Anticoagulation was continued with warfarin. It is rare for IBD patients to have multiple EIMs; however, this case demonstrates that multiple EIMs are a possible presentation in UC and underscores the importance of a meticulous clinical examination and adequate evaluation in the management of IBD patients presenting with EIMs.

ABSTRACT

Background/Aims@#Real-world, clinical practice data are lacking about sofosbuvir/ ribavirin (SOF/RBV) treatment of Korean patients with hepatitis C virus genotype 2 (HCV GT2) infection. This study investigated the efficacy and safety of SOF/RBV in Korean patients with HCV GT2 infection and clinical factors predicting sustained virological response 12 weeks (SVR12) after the end of SOF/RBV treatment. @*Methods@#A total of 181 patients with HCV GT2 with/without cirrhosis were treated with SOF/RBV for 16/12 weeks. Rapid virological response (RVR) was defined as non-detectable HCV RNA at 4 weeks. @*Results@#The RVR rate was 80.7% (146/181), the end of treatment response rate was 97.8% (177/181) and the SVR12 rate was 92.8% (168/181). Of eight patients with relapse, four did not achieve RVR. Three patients had a history of hepatocellular carcinoma (HCC). Multivariable analysis showed that RVR (p = 0.015) and no previous history of HCC (p = 0.007) were associated with SVR12. Factors significantly contributing to RVR included cirrhosis, creatinine concentration, and pre-treatment HCV RNA level. SVR12 rate was significantly higher in RVR (+) than RVR (–) patients (95.2% vs. 82.9%, p = 0.011) and also significantly higher in patients without than with a history of HCC (94.1% vs. 72.7%, p = 0.008). During treatment, 80/181 patients (44.2%) experienced mild to moderate adverse events, with 32 (17.7%) requiring RBV dose reductions due to anemia. @*Conclusions@#SOF/RBV treatment was effective and tolerable in HCV GT2 patients. RVR and no previous history of HCC were positive predictors of SVR12.

ABSTRACT

Background/Aims@#Achalasia is an esophageal motor disorder that leads to functional esophageal obstruction. Food stasis and bacterial fermentation can predispose an individual to esophageal mucosal inflammation, causing multifocal dysplasia and increasing the risk of developing esophageal squamous cell carcinoma. We aimed to evaluate esophageal mucosal alterations in achalasia patients and determine clinical factors associated with the histopathological findings. @*Methods@#From 2009 to 2013, we obtained endoscopic biopsies from the lower and middle esophagus of 22 patients with achalasia and 17 controls. Patients’ clinical data and histological severity of esophagitis were retrospectively analyzed. Additionally, immunohistochemical staining for CD3, CD20, Ki-67, and p53 was conducted. @*Results@#The median age of achalasia patients was 49.5 years (range, 27 to 82 years), and there were nine males (40.9%). The median symptom duration was 5.8 years (range, 1 to 33.5 years), and 10 patients (45%) underwent previous treatment (nine, balloon dilation; one, botulinum toxin injection). Achalasia patients had significantly more severe esophagitis than did controls (p=0.001, lower esophagus; p=0.008, middle esophagus), and the number of CD3-positive lymphocytes exceeded that of CD20-positive lymphocytes (p<0.001). Achalasia patients also had a higher esophageal Ki-67 proliferation index (p=0.048). Although statistically nonsignificant, p53 expression was only observed in achalasia patients. There was no association between the histological severity of esophagitis and other clinicopathological findings. @*Conclusions@#Achalasia patients showed significantly severe histological esophagitis and a high Ki-67 proliferation index, indicating an increased risk of neoplastic progression. Therefore, careful endoscopic inspection is necessary for the early detection of superficial neoplasia in these patients.

ABSTRACT

Background/Aims@#Glecaprevir/pibrentasvir (G/P) is a combination of direct-acting antiviral agents that is an approved treatment for chronic infections by all six hepatitis C virus (HCV) genotypes. However, there are limited data on the effect of G/P in Korean patients in actual real-world settings. We evaluated the real-life effectiveness and safety of G/P at a single institution in Korea. @*Methods@#This retrospective, observational, cohort study used sustained virologic response at 12 weeks after treatment completion (SVR12) as the primary effectiveness endpoint. Safety and tolerability were also determined. @*Results@#We examined 267 individuals who received G/P for chronic HCV infections. There were 148 females (55.4%), and the overall median age was 63.0 years (range, 25 to 87 years). Eightythree patients (31.1%) had HCV genotype-1 and 182 (68.2%) had HCV-2. A total of 212 patients (79.4%) were HCV treatment-naïve, 200 (74.9%) received the 8-week treatment, 13 (4.9%) had received prior treatment for hepatocellular carcinoma, 37 (13.7%) had chronic kidney disease stage 3 or higher, and 10 (3.7%) were receiving dialysis. Intention to treat (ITT) analysis indicated that 256 (95.9%) achieved SVR12. A modified ITT analysis indicated that SVR12 was 97.7% (256/262). Six patients failed therapy because of posttreatment relapse. SVR12 was significantly lower in those who received prior sofosbuvir treatment (p=0.002) and those with detectable HCV RNA at week 4 (p=0.027). Seventy patients (26.2%) experienced one or more adverse events, and most of them were mild. @*Conclusions@#These real-life data indicated that G/P treatment was highly effective and well tolerated, regardless of viral genotype or patient comorbidities.

ABSTRACT

Extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD) is approximately 36%. Of genitourinary complications as an EIM of Crohn’s disease (CD), nephrolithiasis is the most common urinary complication in patients with CD. CD patients have been shown to have decreased urinary volume, pH, magnesium, and excretion of citrate, all of which are significant risk factors for nephrolithiasis. Genitourinary complications often occur in case of a severe longstanding disease and are associated with, the activity of bowel disease, especially in those who have undergone bowel surgery. As uncontrolled nephrolithiasis could impair renal function as well as adversely affect quality of life, proper monitoring, early detection, and prevention of the occurrence of urologic complications in CD is crucial. Few data are available about urolithiasis in patients with CD. Herein we report a case of a successful removal of a 2.7 cm calcium oxalate stone using percutaneous nephrolithotomy from a patient with long-standing CD with a previous surgery for small intestinal and colonic stricture.

ABSTRACT

Purpose@#While the incidence of Barrett’s neoplasia has been increasing in Western countries, the disease remains rare in Asian countries. Therefore, very few studies have investigated the endoscopic treatment for Barrett’s neoplasia in Korea. Endoscopic submucosal dissection (ESD) enables en bloc and complete resection of gastrointestinal neoplastic lesions. This study aimed to evaluate the therapeutic outcomes of ESD for Barrett’s neoplasia in a single center in Korea and to examine the predictive factors for incomplete resection. @*Materials and Methods@#We conducted a retrospective observational study of 18 patients who underwent ESD for superficial Barrett’s neoplasia (dysplasia and early cancer) between January 2010 and December 2019 at Pusan National University Hospital. The therapeutic outcomes of ESD and procedure-related complications were analyzed. @*Results@#En bloc resection, complete resection, and curative resection were performed in 94%, 72%, and 61% of patients, respectively. Histopathology (submucosal or deeper invasion of the tumor) was a significant predictive factor for incomplete resection (P=0.047). Procedure-related bleeding and stenosis were not observed, whereas perforation occurred in one case. During the median follow-up period of 12 months (range, 6–74 months), local recurrence occurred in 2 patients with incomplete resection, one patient underwent repeat ESD, and the other patient received concurrent chemoradiotherapy. The 3-year overall and disease-specific survival rates were 73% and 93%, respectively. @*Conclusions@#ESD seems to be an effective and safe treatment for superficial Barrett’s neoplasia in Korea. Nevertheless, the suitability of ESD for Barrett’s cancer cases should be determined considering the high risk of deep submucosal invasion.

ABSTRACT

Purpose@#A suboptimal nutritional status is often observed among hospitalized patients across all medical/surgical specialties. The objective of the present study was to (1) analyze the prevalence of malnutrition in severe trauma patients and (2) evaluate the relationship between malnutrition and select clinical outcomes. @*Materials and Methods@#This retrospective study was conducted between October 2015 and March 2017 at the Pusan National University Hospital Trauma Center. Of a total of 3,560 patients, 945 were enrolled in this study. Patients were checked for malnutrition using a nutrition assessment tool by the hospital nutrition support team. The parameters assessed included serum albumin, the ratio of actual body weight to ideal body weight (%), total lymphocyte count, appetite, and gastrointestinal problems. Clinical outcomes under consideration included 1) mortality, 2) length of hospitalization, and 3) length of stay in the intensive care unit (ICU). @*Results@#The total prevalence of malnutrition in hospitalized trauma patients was 55.0% (n=520). Malnutrition risk was the independent prognostic factor of mortality in severe trauma patients (adjusted odds ratio [OR]=3.440;95% confidence interval [CI]=1.401~8.447, P=0.007). Risk factors of malnutrition were age over 65 years (adjusted OR=2.393; 95% CI=1.699~3.370, P<0.001), injury severity score (adjusted OR=1.034, 95% CI=1.012~1.056, P=0.002), length of hospitalization (adjusted OR=1.104; 95% CI=1.007~1.020, P<0.001), and length of stay in the ICU (adjusted OR=1.050; 95% CI=1.029~1.072, P<0.001). @*Conclusion@#Malnutrition is widespread in hospitalized patients with severe trauma and results in suboptimal clinical outcomes. Thus, patients at high risk of malnutrition should be monitored carefully during hospitalization.

ABSTRACT

Intussusception is a medical condition, in which a proximal part of the intestine folds into the distal intestine. Adult intussusceptions are rare and account for approximately 5% of all cases of intussusceptions. The anatomical leading points include tumors, diverticulums, polyps, and strictures in 80-90% of adult intussusceptions, and 65% of colon intussusceptions and 30% of small bowel intussusceptions originate from malignant tumors. Treatments for adult intussusception have not been established, but most cases require surgical treatment. The gastrointestinal tract is the most common extranodal site for non-Hodgkin lymphoma. The symptoms are mostly non-specific, but they rarely lead to complications, such as bleeding, perforation, and intussusception. Furthermore, few cases of primary gastrointestinal lymphomas causing intussusception have been reported. This paper reports a case of small bowel diffuse large B cell lymphoma that caused ileocolic intussusception in a 69-year-old woman with no medical history. She underwent a small bowel resection and received six cycles of adjuvant chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone. Since then, she has been in complete remission.

ABSTRACT

Background@#/Aim: Percutaneous transhepatic cholangioscopy (PTCS) has been widely used for the diagnosis and treatment. PTCS-related complications (hemobilia, cholangitis, biliary tract perforations) are not infrequent. However, data on the risk factors for PTCS-related complications are limited. Therefore, we aimed to identify the risk factors for PTCS-related complications. @*Methods@#Two hundred thirty-three patients who underwent PTCS at a single tertiary center between January 2006 and October 2014 were enrolled. After retrospectively analyzing the patients’ medical records, 212 patients were enrolled and classified into two groups: 1) a complication group and 2) a non-complication group. @*Results@#The study population comprised 112 men and 100 women, with a median age of 64.5 years. Of the 212 patients, 32 (15.1%) developed complications: 14 (6.7%) developed cholangitis, six (2.8%) developed bile duct injury, and two (0.9%) developed hemobilia. In the univariate analyses, older age, a small number of tract dilatation sessions, and computed tomography (CT) findings of liver cirrhosis and a non-dilated intrahepatic duct were risk factors for PTCS-related complications. In the multivariate analysis, older age, a small number of tract dilatation sessions, and the CT finding of a non-dilated intrahepatic duct were independent factors for predicting PTCS-related complications. Serial tract dilatations (≥2 sessions) were performed in 95 patients (44.8%), but this did not affect the complication rate. In this subgroup of patients, a short interval between sessions (≤3 days) was associated with PTCSrelated complications. @*Conclusions@#Elderly patients and those with non-dilated intrahepatic ducts on CT need to be managed carefully. Stepwise tract dilatations and a long interval between sessions (>3 days) can help decrease PTCS-related complications.

ABSTRACT

BACKGROUND/AIMS: Cooperation of patients plays an essential role during gastric endoscopic submucosal dissection (ESD) for successful outcomes. We aimed to assess the efficacy and safety of a patient-positioning device (EZ-FIX®) during ESD for gastric epithelial neoplasm.MATERIALS AND METHODS: In this prospective study, 86 consecutive patients with gastric epithelial neoplasm scheduled for ESD at the Pusan National University Hospital were included and randomly assigned to the EZ-FIX® (n=44) or non-EZ-FIX® (n=42) groups. The primary outcomes measured were endoscopist satisfaction profiles and contribution level of EZ-FIX® to the procedure.RESULTS: No significant differences were observed between the two groups regarding patients' clinicopathologic characteristics, though the mean procedure time was longer in the EZ-FIX® group (P=0.044). In the EZ-FIX® group, 16 patients (36.4%) were categorized as a contribution group. Subgroup analysis between the contribution and non-contribution groups revealed that the contribution group had a larger lesion size (P=0.043) and a longer procedure time (P=0.037) and showed a higher patient's movement score (P < 0.001) with a higher dosage of propofol (P=0.004) and pethidine (P=0.001) required. Endoscopist satisfaction scores on sedation (P < 0.001) and overall procedure (P=0.010) were lower in the contribution group.CONCLUSIONS: Thus, EZ-FIX® might be helpful especially for patients who are expected to exhibit uncooperative sedation or those with a large lesion size, which would necessitate a longer procedure time.

ABSTRACT

BACKGROUND/AIMS: Proton pump inhibitors are widely used to prevent gastric endoscopic submucosal dissection (ESD)-related bleeding, but no standard administration regimens have been established. We aimed to prospectively compare the effects of continuous infusion and intermittent dosing with pantoprazole on preventing gastric ESD-related bleeding. Additionally, we analyzed the risk factors for bleeding. METHODS: From April 2012 to May 2013, patients with a gastric epithelial neoplasm scheduled for ESD in the Pusan National University Hospital were randomly assigned to one of two groups according to the pantoprazole administration regimen (continuous infusion or intermittent dosing). The primary outcomes measured were intra- and postprocedural bleeding events. RESULTS: The final analysis included 401 patients. The rate of significant intraprocedural bleeding was 25.4% in the C group and 24.0% in the I group, with no significant difference (p=0.419). In addition, there was no significant difference in the postprocedural bleeding rate between the C and I groups (11.7% vs 10.2%, p=0.374). Multivariate analysis showed that intraprocedural bleeding was associated with the proximal tumor location, the presence of fibrosis, and the size of the resected specimen, whereas postprocedural bleeding was associated with the size of the resected specimen and the procedure/coagulation time. CONCLUSIONS: Intermittent dosing with pantoprazole is sufficient and cost-effective for the prevention of gastric ESD-related bleeding. Operators should consider tumor characteristics when planning ESD to minimize the risk of intraprocedural bleeding, and patients with large iatrogenic ulcers should be carefully monitored for postprocedural bleeding.

ABSTRACT

BACKGROUND: Malnutrition is associated with many adverse clinical outcomes. The present study aimed to identify the prevalence of malnutrition in hospitalized patients in Korea, evaluate the association between malnutrition and clinical outcomes, and ascertain the risk factors of malnutrition. METHODS: A multicenter cross-sectional study was performed with 300 patients recruited from among the patients admitted in 25 hospitals on January 6, 2014. Nutritional status was assessed by using the Subjective Global Assessment (SGA). Demographic characteristics and underlying diseases were compared according to nutritional status. Logistic regression analysis was performed to identify the risk factors of malnutrition. Clinical outcomes such as rate of admission in intensive care units, length of hospital stay, and survival rate were evaluated. RESULTS: The prevalence of malnutrition in the hospitalized patients was 22.0%. Old age (≥ 70 years), admission for medical treatment or diagnostic work-up, and underlying pulmonary or oncological disease were associated with malnutrition. Old age and admission for medical treatment or diagnostic work-up were identified to be risk factors of malnutrition in the multivariate analysis. Patients with malnutrition had longer hospital stay (SGA A = 7.63 ± 6.03 days, B = 9.02 ± 9.96 days, and C = 12.18 ± 7.24 days, P = 0.018) and lower 90-day survival rate (SGA A = 97.9%, B = 90.7%, and C = 58.3%, P < 0.001). CONCLUSION: Malnutrition was common in hospitalized patients, and resulted in longer hospitalization and associated lower survival rate. The rate of malnutrition tended to be higher when the patient was older than 70 years old or hospitalized for medical treatment or diagnostic work-up compared to elective surgery.

ABSTRACT

BACKGROUND/AIMS: Pancreatic pseudocyst is a common complication of acute and chronic pancreatitis. Endoscopy ultrasound (EUS)-guided drainage includes multiple steps and requires many resources such as a linear echoendoscope and a fluoroscopy room, which may not be available at all medical centers. We aimed to evaluate the efficacy and safety of EUS-guided pancreatic pseudocyst drainage without fluoroscopy. METHODS: This retrospective study analyzed 10 patients who had undergone EUS-guided transmural drainage of pancreatic pseudocyst without use of fluoroscopy at the Pusan National University Hospital between January 2009 and December 2016. Drainage was performed via a transgastric approach and one or two 7 Fr double-pigtail stents were inserted. RESULTS: The technical success rate was 100% and the clinical success rate was 80%. In two patients, clinical success was not achieved and additional percutaneous catheter drainage was done. Therefore, pseudocysts in all the patients were treated successfully without surgical drainage. However, there were three adverse events in three patients: bleeding, infection, and stent migration in each respective patient. During the median follow-up period of 36.5 months, there was no recurrence of pseudocysts in any of the patients. CONCLUSIONS: EUS-guided transmural drainage of pseudocyst drainage without use of fluoroscopy is a technically feasible, safe, and effective procedure for the treatment of pancreatic pseudocyst.
