Survey-Based Analysis of the Clinical Treatment Status of Irritable Bowel Syndrome in Korea

Background@#The quality-of-life of patients with irritable bowel syndrome is low; incorrect diagnosis/treatment causes economic burden and inappropriate consumption of medical resources. This survey-based study aimed to analyze the current status of irritable bowel syndrome treatment to examine differences in doctors’ perceptions of the disease, and treatment patterns. @*Methods@#From October 2019 to February 2020, the irritable bowel syndrome and Intestinal Function Research Study Group of the Korean Society of Neurogastroenterology and Motility conducted a survey on doctors working in primary, secondary, and tertiary healthcare institutions. The questionnaire included 37 items and was completed anonymously using the NAVER platform (a web-based platform), e-mails, and written forms. @*Results@#A total of 272 doctors responded; respondents reported using the Rome IV diagnostic criteria (amended in 2016) for diagnosing and treating irritable bowel syndrome.Several differences were noted between the primary, secondary, and tertiary physicians’ groups. The rate of colonoscopy was high in tertiary healthcare institutions. During a colonoscopy, the necessity of random biopsy was higher among physicians who worked at tertiary institutions. ‘The patient did not adhere to the diet’ as a reason for ineffectiveness using low-fermentable oligo-, di-, and mono-saccharides, and polyols diet treatment was higher among physicians in primary/secondary institutions, and ‘There are individual differences in terms of effectiveness’ was higher among physicians in tertiary institutions. In irritable bowel syndrome constipation predominant subtype, the use of serotonin type 3 receptor antagonist (ramosetron) and probiotics was higher in primary/secondary institutions, while serotonin type 4 receptor agonist was used more in tertiary institutions. In irritable bowel syndrome diarrhea predominant subtype, the use of antispasmodics was higher in primary/secondary institutions, while the use of serotonin type 3 receptor antagonist (ramosetron) was higher in tertiary institutions. @*Conclusion@#Notable differences were observed between physicians in primary/secondary and tertiary institiutions regarding the rate of colonoscopy, necessity of random biopsy, the reason for the ineffectiveness of low-fermentable oligo-, di-, and mono-saccharides, and polyols diet, and use of drug therapy in irritable bowel syndrome. In South Korea, irritable bowel syndrome is diagnosed and treated according to the Rome IV diagnostic criteria, revised in 2016.

Intrahepatic Cholangiocarcinoma Arising from Biliary Hamartomas in Patients with Recurrent Acute Cholangitis: A Case Report and Literature Review / 대한소화기학회지

Biliary hamartomas are tumor-like malformations of the liver. Biliary hamartomas are a type of fibrocystic disorder originating from ductal plate malformation and are typically considered benign, but with the risk of malignant transformation. In this case report, we present a rare occurrence of intrahepatic cholangiocarcinoma (ICC) that developed from biliary hamartomas, along with a literature review. A 76-year-old man with a diagnosis of biliary hamartomas had a history of recurrent cholangitis for 12 years, necessitating cholecystectomy, ERCP, and repeated antibiotic treatments. During his last episode, imaging studies revealed a hypervascular infiltrative mass in the right posterior liver segment. A liver biopsy confirmed adenocarcinoma and subsequent surgical pathology revealed ICC originating from biliary hamartomas. Chronic inflammation in the bile duct associated with biliary hamartomas may serve as a potential trigger for malignant transformation, as observed in this case. Therefore, close surveillance is essential for patients with biliary hamartomas presenting with infectious complications.

On-demand Versus Continuous Maintenance Treatment With a Proton Pump Inhibitor for Mild Gastroesophageal Reflux Disease: A Prospective Randomized Multicenter Study

Background/Aims@#It remains unclear which maintenance treatment modality is most appropriate for mild gastroesophageal reflux disease (GERD).We aimed to compare on-demand treatment with continuous treatment using a proton pump inhibitor (PPI) in the maintenance treatment for patients with non-erosive GERD or mild erosive esophagitis. @*Methods@#Patients whose GERD symptoms improved after 4 weeks of standard dose PPI treatment were prospectively enrolled at 25 hospitals.Subsequently, the enrolled patients were randomly assigned to either an on-demand or a continuous maintenance treatment group, and followed in an 8-week interval for up to 24 weeks. @*Results@#A total of 304 patients were randomized to maintenance treatment (continuous, n = 151 vs on-demand, n = 153). The primary outcome, the overall proportion of unwillingness to continue the assigned maintenance treatment modality, failed to confirm the noninferiority of on-demand treatment (45.9%) compared to continuous treatment (36.1%). Compared with the on-demand group, the GERD symptom and health-related quality of life scores significantly more improved and the overall satisfaction score was significantly higher in the continuous treatment group, particularly at week 8 and week 16 of maintenance treatment. Work impairment scores were not different in the 2 groups, but the prescription cost was less in the on-demand group. Serum gastrin levels significantly elevated in the continuous treatment group, but not in the on-demand group. @*Conclusions@#Continuous treatment seems to be more appropriate for the initial maintenance treatment of non-erosive GERD or mild erosive esophagitis than on-demand treatment. Stepping down to on-demand treatment needs to be considered after a sufficient period of continuous treatment.

Efficacy and Safety of Fexuprazan in Patients with Acute or Chronic Gastritis

Background/Aims@#Fexuprazan is a novel potassium-competitive acid blocker that could be of benefit to patients with gastric mucosal injury. The aim of this study was to assess the 2-week efficacy and safety of fexuprazan in patients with acute or chronic gastritis. @*Methods@#In this study, 327 patients with acute or chronic gastritis who had one or more gastric erosions on endoscopy and subjective symptoms were randomized into three groups receiving fexuprazan 20 mg once a day (q.d.), fexuprazan 10 mg twice a day (b.i.d.), or placebo for 2 weeks. The posttreatment assessments were the primary endpoint (erosion improvement rate), secondary endpoints (cure rates of erosion and edema and improvement rates of redness, hemorrhage, and subjective symptoms), and drug-related adverse events. @*Results@#Among the patients, 57.8% (59/102), 65.7% (67/102), and 40.6% (39/96) showed erosion improvement 2 weeks after receiving fexuprazan 20 mg q.d., fexuprazan 10 mg b.i.d., and placebo, respectively. Both fexuprazan 20 mg q.d. and 10 mg b.i.d. showed superior efficacy to the placebo (p=0.017 and p<0.001, respectively). Likewise, both fexuprazan 20 mg q.d. and 10 mg b.i.d. also showed higher erosion healing rates than the placebo (p=0.033 and p=0.010, respectively). No difference was noted in the edema healing rate and the improvement rates for redness, hemorrhage, and subjective symptoms between the fexuprazan and placebo groups.No significant difference was noted in the incidence of adverse drug reactions. @*Conclusions@#Fexuprazan 20 mg q.d. and 10 mg b.i.d. for 2 weeks showed therapeutic efficacy superior to that of placebo in patients with acute or chronic gastritis (ClinicalTrials.gov identifier NCT04341454).

Efficacy of a Restrictive Diet in Irritable Bowel Syndrome: A Systematic Review and Network Meta-analysis / 대한소화기학회지

Background/Aims@#Dietary factors can aggravate the symptoms of irritable bowel syndrome (IBS). Many IBS patients try restrictive diets to relieve their symptoms, but the types of diets with an exacerbating factor are unknown. Therefore, this paper reports the results of a systematic review and network meta-analysis of randomized-controlled trials (RCTs) reviewing the efficacy of food restriction diets in IBS. @*Methods@#The MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov databases were searched until July 21, 2021, to retrieve RCTs assessing the efficacy of restriction diets in adults with IBS. Two independent reviewers performed the eligibility assessment and data abstraction. RCTs that evaluated a restriction diet versus a control diet and assessed the improvement in global IBS symptoms were included. These trials reported a dichotomous assessment of the overall response to therapy. @*Results@#A total of 1,949 citations were identified. After full-text screening, 14 RCTs were considered eligible for the systematic review and network meta-analysis. A starch- and sucrose-reduced diet and a diet with low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) showed significantly better results than a usual diet. Symptom flare-ups in patients on a gluten-free diet were also significantly lower than in those on high-gluten diets. @*Conclusions@#These findings showed that the starch- and sucrose-reduced, low FODMAP, and gluten-free diets had superior effects in reducing IBS symptoms. Further studies, including head-to-head trials will be needed to establish the effectiveness of dietary restrictions on IBS symptoms.

Primary Aortoduodenal Fistula Causes Massive Melena: A Case Report / 대한소화기학회지

A primary aortoenteric fistula is defined as the spontaneous development of communication between the gastrointestinal tract and the native aorta. This is unlike a secondary aortoenteric fistula that occurs after surgery, such as a vascular graft. A primary aortoenteric fistula is an extremely rare cause of upper gastrointestinal bleeding. The condition is often overlooked because of its extremely low incidence. This paper reports a case of a 75-year-old man who presented with massive melena. Esophagogastroduodenoscopy revealed an ulcer measuring approximately 1.3 cm with a huge pulsating vessel in the third portion of the duodenum. Later, the diagnosis of primary aortoduodenal fistula was confirmed. The patient died in the preoperative stage due to massive bleeding. The findings of this case suggest that the endoscopists should recognize aortoenteric fistula as a potential cause of gastrointestinal bleeding.

Esophageal Stricture Caused by the Ingestion of Undissolved Picosulfate Powder

Picosulfate solution is widely used as a small volume bowel cleansing agent and is considered to be effective and relatively safe. A case of a 75-year-old woman ingested picosulfate powder and drank a small volume of water, subsequently experienced severe burning pain in the chest. Endoscopy was performed and showed a submucosal hemorrhage and exudative ulcers at the mid to lower esophagus. At 2 weeks, her symptoms improved with conservative treatment. However, liquid food dysphagia developed 11 weeks after ingestion. A follow-up endoscopy revealed multiple esophageal strictures, which were treated with a fully covered metal stent and esophageal balloon dilation. Consequently, the esophageal strictures improved after one year. As this case demonstrates, detailed information about picosulfate powder ingestion after dissolving it in more than 200 mL of water should be presented to patients to avoid esophageal injury.

Inflammatory Bowel Disease and Vitamin D / 대한소화기학회지

Vitamin D contributes to bone metabolism and acts as an immune modulator for both innate and adaptive immunity. The serum level of vitamin D has been associated with inflammatory diseases, such as inflammatory bowel disease (IBD). In epidemiologic studies, IBD patients have been shown to have low levels of vitamin D. The suboptimal circulating levels of vitamin D in IBD patients may be caused by low exposure to sunlight, dietary malabsorption, and the impaired conversion of active metabolites (1,25[OH] 2D). Recent studies have demonstrated that vitamin D deficiency in IBD can increase the chance of disease recurrence, IBD-related hospitalization or surgery, and deterioration of quality of life. Supplementation with vitamin D is therefore thought to reduce the risk of flare-ups and the improvement of the quality of life in IBD patients. This review aims to summarize the latest knowledge on the effects of vitamin D deficiency on IBD and the possible benefits of vitamin D supplementation in IBD patients.

Predictors of Malignancies in Patients with Inconclusive or Negative Results of Endoscopic Ultrasound-guided Fine-needle Aspiration for Solid Pancreatic Masses / 대한소화기학회지

BACKGROUND/AIMS: This study analyzed the diagnostic accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for pancreatic solid masses in patients with or without chronic pancreatitis as well as the clinical parameters relevant to a malignancy when EUS-FNA was negative or inconclusive. METHODS: A total of 97 patients, who underwent EUS-FNA for solid pancreatic masses over 2 years at a single institution, were evaluated. All patients underwent EUS-FNA for 3-5 passes with 22 or 25 G needles without an on-site cytopathologist. The final diagnosis was obtained by surgery or compatible clinical outcomes for a more than 12 month follow-up. The diagnostic yields in the patients with or without chronic pancreatitis were compared and the histories and laboratory data relevant to pancreatic ductal adenocarcinoma (PDAC) or pseudo-tumor were analyzed. RESULTS: The final diagnoses were adenocarcinoma in 88 patients (90.7%) and inflammatory pseudo-tumor in 9 (9.3%). The results of EUS-FNA were adenocarcinoma (74), suspicious (7), atypical (5), negative (10), and inadequate specimen (1). The diagnostic accuracies were 76.9% and 91.6% in patients with or without chronic pancreatitis, respectively. Among the 23 cases with non-diagnostic results of EUS-FNA, PDAC was finally diagnosed in 5 out of 7 suspicious, 3 out of 5 atypical, and 5 out of 10 negative cytology cases. The clinical parameters related to a pseudo-tumor were a history of alcohol consumption and pancreatitis, and normal alkaline phosphatase levels. CONCLUSIONS: The diagnostic accuracy of pancreatic masses in the background of chronic pancreatitis was low. When EUS-FNA produced inconclusive results, the histories of alcohol consumption, pancreatitis, and serum levels of alkaline phosphatase are useful for making a final diagnosis.

Diagnostic and prognostic value of preoperative ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography for colorectal cancer: comparison with conventional computed tomography

BACKGROUND/AIMS: ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has been used for preoperative staging of colorectal cancer (CRC). However, the diagnostic accuracy of FDG-PET/CT for detection of lymph node or distant metastasis and its prognostic role have not been well established. We therefore evaluated the diagnostic and prognostic value of FDG-PET/CT in comparison with conventional CT for CRC. METHODS: We investigated 220 patients who underwent preoperative FDG-PET/CT and CT, followed by curative surgery for CRC. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of FDG-PET/CT and CT for detection of lymph node metastasis and distant metastasis were evaluated. In addition, we assessed the findings of FDG-PET/CT and CT according to outcomes, including cancer recurrence and cancer-related death, for evaluation of prognostic value. RESULTS: For detection of lymph node metastasis, FDG-PET/CT had a sensitivity of 44%, a specificity of 84%, and an accuracy of 67%, compared with 59%, 65%, and 62%, respectively, for CT (P=0.029, P=0.000, and P=0.022). For distant metastasis, FDG-PET/CT had a sensitivity of 79%, a specificity of 94%, and an accuracy of 93%, compared with 79%, 87%, and 86%, respectively, for CT (P=1.000, P=0.004, and P=0.037). In addition, positive findings of lymph node metastasis and distant metastasis on FDG-PET/CT were associated significantly with cancer recurrence or cancer-related death (P=0.009, P=0.001, respectively). CONCLUSIONS: Preoperative FDG-PET/CT had a higher specificity and accuracy compared to CT for detection of lymph node metastasis and distant metastasis of CRC. In addition, FDG-PET/CT could be a valuable prognostic tool for CRC.

Clinical features of gastric emptying after distal gastrectomy

PURPOSE: Gastric emptying may influence the quality of life of patients who undergo distal gastrectomy. Little is known, however, about gastric emptying after distal gastrectomy. The aim of our study was to investigate gastric emptying patterns after distal gastrectomy. METHODS: This gastric-emptying study investigated patients who underwent distal gastrectomy in the 6 months or more before May 2008 to July 2013 at Chungbuk National University Hospital with a study sample of 205 patients. We analyzed patterns of gastric emptying. RESULTS: Delayed gastric emptying was found in 109 of the 205 patients (53.2%). Food stasis was more frequent in a group with delayed gastric emptying. In multivariate analysis, risk factors for gastroparesis were laparoscopic operation (hazard ratio [HR], 2.731; P = 0.008) and duration of less than 24 months after distal gastrectomy (HR, 2.795; P = 0.001). Delayed gastric emptying tended to decrease with duration of the postoperative period. CONCLUSION: Delayed gastric emptying is common in distal gastrectomy, and is related to laparoscopic operation and duration of the postoperative period. Food stasis was more frequent in a group with delayed gastric emptying.

The Usefulness of Early Endoscopic Ultrasonography in Acute Biliary Pancreatitis with Undetectable Choledocholithiasis on Multidetector Computed Tomography / 대한소화기학회지

BACKGROUND/AIMS: EUS can detect bile duct stones (BDS) that are undetectable on multidetector computed tomography (MDCT). BDS associated with acute biliary pancreatitis (ABP) are small and tend to be excreted spontaneously. This study evaluated the usefulness of early EUS in patients with ABP and undetectable BDS on MDCT. METHODS: Forty-one patients with ABP and undetectable BDS on MDCT underwent EUS within 24 hours of admission and were diagnosed with BDS, sludge, dilated common bile duct (CBD), or normal CBD. ERCP was performed in patients with BDS, sludge, or clinical deterioration. The diagnostic yield and the effects of early EUS on morbidity, mortality, and the length of hospitalization were evaluated. RESULTS: EUS detected BDS or sludge in 48.8% of patients examined. BDS was the diagnosis in 13 patients, sludge in seven, and neither for 21 patients. ERCP was performed in 20 patients with BDS or sludge, in two patients with coexisting cholangitis, and in one patient with worsening liver function tests. ERCP identified BDS in 12 patients and sludge in seven. No lesions were diagnosed in four patients by ERCP. All patients improved, and the length of hospitalization in patients with ERCP was 9.0 days, without ERCP 7.1 days. Two patients with major complications by ERCP were hospitalized for a prolonged time. CONCLUSIONS: Early EUS may be useful to select patients for therapeutic ERCP in cases of suspected ABP with undetectable BDS on MDCT.

Diagnostic Accuracy of the Initial Endoscopy for Ampullary Tumors

BACKGROUND/AIMS: Ampullary tumors come in a wide variety of malignant forms. We evaluated the diagnostic accuracy of endoscopy for ampullary tumors, and analyzed the causes of misdiagnosis. METHODS: We compared endoscopic imaging and biopsy results to final diagnoses. Types of endoscope, numbers of biopsy specimens taken, and final diagnoses were evaluated as possible factors influencing diagnostic accuracy. RESULTS: Final diagnoses were 19 adenocarcinomas, 18 normal or papillitis, 11 adenomas, two adenomyomas, one paraganglioma, and one neuroendocrine tumor. The diagnostic accuracy of endoscopic imaging or the initial biopsy was identical (67.3%). At least one test was concordant with the final diagnosis in all except two cases. Compared with the final diagnosis, endoscopic imaging tended to show more advanced tumors, whereas the initial biopsy revealed less advanced lesions. The diagnostic accuracy of the initial biopsy was influenced by the type of endoscope used and the final diagnosis, but not by the number of biopsies taken. CONCLUSIONS: Endoscopy has limited accuracy in the diagnosis of ampullary tumors. However, most cases with concordant endoscopic imaging and biopsy results are identical to the final diagnosis. Therefore, in cases where both of these tests disagree, re-evaluation with a side-viewing endoscope after resolution of papillitis is required.

A Case of Combined Congenital Hepatic Fibrosis and Biliary Hamartoma Presented with Recurrent Acute Cholangitis / 대한췌담도학회지

Biliary hamartoma and congenital hepatic fibrosis belong to fibrocystic disorders originating from ductal plate malformation. A 66-year-old man who had incidentally been diagnosed with biliary hamartoma two years ago presented to us with recurrent acute cholangitis. In the first episode, he had presented with septic shock and was treated with endoscopic retrograde cholangiopancreatography (ERCP) and cholecystectomy under the diagnosis of acute cholecystitis and cholangitis. However, during a two-month follow-up period, the patient experienced four episodes of acute cholangitis. Because he showed normal ERCP, and biliary hamartoma is usually asymptomatic, a liver biopsy was performed. Pathology revealed combined features of biliary hamartoma and congenital hepatic fibrosis, characterized as periportal fibrosis and intrahepatic ductular dysplasia. During follow-up for the last six months, he had experienced two episodes of acute cholangitis and was treated with antibiotics. A follow-up abdominal CT scan revealed aggravated hepatosplenomegaly compared to that of two years ago. We report a case of combined congenital hepatic fibrosis and biliary hamartoma and a literature review.

The Effect of Urocortin 1 on Motility in Isolated, Vascularly Perfused Rat Colon / 대한소화기학회지

BACKGROUND/AIMS: Urocortin 1, a corticotropin-releasing factor related peptide, increases colonic motility under stressful conditions. We investigated the effect of urocortin 1 on colonic motility using an experimental model with isolated rat colon in which the blood flow and intestinal nerves were preserved. Furthermore, we assessed whether this effect was mediated by adrenergic or cholinergic nerves. METHODS: Colonic motility was measured in the proximal and distal parts of resected rat colon. The colon resected from the peritoneum was stabilized, and then urocortin 1 (13.8, 138, 277, and 1,388 pM) was administered via a blood vessel. Motility index was measured in the last 5 min of the 15 min administration of urocortin 1 and expressed as percentage change from baseline. Subsequently, the change in motility was measured by perfusing urocortin 1 in colons pretreated with phentolamine, propranolol, hexamethonium, atropine, or tetrodotoxin. RESULTS: At concentrations of 13.8, 138, 277, and 1,388 pM, urocortin 1 increased the motility of proximal colon (20.4+/-7.2%, 48.4+/-20.9%, 67.0+/-25.8%, and 64.2+/-20.9%, respectively) and the motility of distal colon (3.3+/-3.3%, 7.8+/-7.8%, 71.1+/-28.6%, and 87.4+/-32.5%, respectively). The motility induced by urocortin 1 was significantly decreased by atropine to 2.4+/-2.4% in proximal colon and 3.4+/-3.4% in distal colon (p<0.05). However, tetrodotoxin, propranolol, phentolamine, and hexamethonium did not inhibit motility. CONCLUSIONS: Urocortin 1 increased colonic motility and it is considered that this effect was directly mediated by local muscarinic cholinergic receptors.

Endoscopy for Nonvariceal Upper Gastrointestinal Bleeding

Endoscopy for acute nonvariceal upper gastrointestinal bleeding plays an important role in primary diagnosis and management, particularly with respect to identification of high-risk stigmata lesions and to providing endoscopic hemostasis to reduce the risk of rebleeding and mortality. Early endoscopy, defined as endoscopy within the first 24 hours after presentation, improves patient outcome and reduces the length of hospitalization when compared with delayed endoscopy. Various endoscopic hemostatic methods are available, including injection therapy, mechanical therapy, and thermal coagulation. Either single treatment with mechanical or thermal therapy or a treatment that combines more than one type of therapy are effective and safe for peptic ulcer bleeding. Newly developed methods, such as Hemospray powder and over-the-scope clips, may provide additional options. Appropriate decisions and specific treatment are needed depending upon the conditions.

A Case of Choledocholithiasis and Intestinal Malrotation in an Adolescent with Repaired Gastroschisis

Most infants with repaired gastroschisis develop normally and remain in good health. About 10% of patients with gastroschisis have other malformations. We report a case of choledocholithiasis and intestinal malrotation in an adolescent with repaired gastroschisis. A 17-year-old girl presented with fever, jaundice, and abdominal pain. She had undergone an operation to repair gastroschisis at birth. Physical examination revealed icteric sclera, a tight abdominal wall, and a longitudinal surgical scar at the midline. An abdominal computed tomography scan revealed a round calcifying lesion near the pancreas and a midline-positioned liver and gallbladder. Absence of the retroperitoneal duodenum and the anterior and left-sided position of the superior mesenteric vein compared with the superior mesenteric artery were observed. Results of abarium examination revealed intestinal malrotation. Endoscopic retrograde cholangiopancreatography revealed diffuse dilatation of the biliary trees and a malpositioned gallbladder. A single stone was removed by using a basket. The clinical symptoms improved after the patient underwent endoscopic retrograde cholangiopancreatography.
