Background/Aims@#Prokinetic agents and neuromodulators are among the treatment options for functional dyspepsia (FD), but their comparative efficacy is unclear. We aimed to compare the efficacy of mosapride controlled-release (CR) and nortriptyline in patients with FD after 4 weeks of treatment. @*Methods@#Participants with FD were randomly assigned (1:1) to receive mosapride CR (mosapride CR 15 mg and nortriptyline placebo) or nortriptyline (mosapride CR placebo and nortriptyline 10 mg) in double-placebo, double-blinded, randomized controlled, parallel clinical study. The primary endpoint was defined as the proportion of patients with overall dyspepsia improvement after 4 weeks treatment. The secondary endpoints were changes in individual symptom scores, anxiety, depression, and quality of life. @*Results@#One hundred nine participants were recruited and assessed for eligibility, and 54 in the mosapride CR group and 50 in the nortriptyline group were included in the modified intention-to-treat protocol. The rate of overall dyspepsia improvement was similar between groups (53.7% vs 54.0%, P = 0.976). There was no difference in the efficacy of mosapride CR and nortriptyline in a subgroup analysis by FD subtype (59.3% vs 52.5% in postprandial distress syndrome, P = 0.615; 44.4% vs 40.0% in epigastric pain syndrome, P = > 0.999; 50.0% vs 59.1% in overlap, P = 0.565; respectively). Both treatments significantly improved anxiety, depression, and quality of life from baseline. @*Conclusion@#Mosapride CR and nortriptyline showed similar efficacy in patients with FD regardless of the subtype. Both treatments could be equally helpful for improving quality of life and psychological well-being while also relieving dyspepsia.

Background/Aims@#Acid-suppressive drugs, such as proton pump inhibitors (PPIs), are treatment options for functional dyspepsia (FD). However, the efficacy of potassium-competitive acid blockers (P-CABs) in treating FD has not yet been established. This prospective multicenter clinical trial-based study aimed to assess the efficacy and safety of tegoprazan as a P-CAB treatment in patients with FD. @*Methods@#FD was diagnosed using the Rome IV criteria. All patients received tegoprazan 50 mg once daily for 8 weeks. Dyspeptic symptoms were assessed using a dyspepsia symptom questionnaire (5-point Likert scale, Nepean Dyspepsia Index-Korean [NDI-K], and gastroesophageal reflux disease–health-related quality of life [GERD-HRQL]). The main outcome was satisfactory symptom relief rates at 8 weeks. @*Results@#In this study, from the initial screening of 209 patients, 173 were included in the per-protocol set analysis. Satisfactory symptom relief rates at 8 and 4 weeks were 86.7% and 74.6%, respectively. In addition, the NDI-K and GERD-HRQL scores significantly improved at 8 and 4 weeks compared with the baseline scores. The efficacy of tegoprazan was not influenced by the FD subtype or Helicobacter pylori status. In patients with overlapping FD and GERD, there was a greater improvement in the NDI-K and GERD-HRQL scores than in patients with FD symptoms only. No serious drug-related adverse events occurred during this study. @*Conclusion@#Tegoprazan (50 mg) administered once daily provided satisfactory symptom relief for FD.
摘要
Chronic constipation is one of the most common digestive diseases encountered in clinical practice. Constipation manifests as a variety of symptoms, such as infrequent bowel movements, hard stools, feeling of incomplete evacuation, straining at defecation, a sense of anorectal blockage during defecation, and use of digital maneuvers to assist defecation. During the diagnosis of chronic constipation, the Bristol Stool Form Scale, colonoscopy, and a digital rectal examination are useful for objective symptom evaluation and differential diagnosis of secondary constipation. Physiological tests for functional constipation have complementary roles and are recommended for patients who have failed to respond to treatment with available laxatives and those who are strongly suspected of having a defecatory disorder. As new evidence on the diagnosis and management of functional constipation emerged, the need to revise the previous guideline was suggested. Therefore, these evidence-based guidelines have proposed recommendations developed using a systematic review and meta-analysis of the treatment options available for functional constipation. The benefits and cautions of new pharmacological agents (such as lubiprostone and linaclotide) and conventional laxatives have been described through a meta-analysis. The guidelines consist of 34 recommendations, including 3 concerning the definition and epidemiology of functional constipation, 9 regarding diagnoses, and 22 regarding managements. Clinicians (including primary physicians, general health professionals, medical students, residents, and other healthcare professionals) and patients can refer to these guidelines to make informed decisions regarding the management of functional constipation.

Background/Aims@#Patient-reported outcomes (PROs) are essential for clinical decision making, conduction of clinical research, and drug application acquisition in functional gastrointestinal disorders. The aim of this study is to develop a PRO instrument and to determine the respondents’ perception of the efficacy of therapeutic agents for functional dyspepsia (FD). @*Methods@#A self-evaluation questionnaire for dyspepsia (SEQ-DYSPEPSIA) was developed and validated through a structured process. The 2-week reproducibility was evaluated, and the construct validity was assessed by correlating the scores of SEQ-DYSPEPSIA (including typical and major FD symptom subscales). Finally, the response to medication was assessed by comparing the changes after 4 weeks of treatment. @*Results@#A total of 193 Korean patients (age 48.5 ± 13.6 years, 69.4% women) completed the questionnaire. SEQ-DYSPEPSIA with 11 items had a good internal consistency (alpha = 0.770-0.905) and an acceptable test-retest reliability (intraclass correlation coefficient = 0.733-0.859). The self-evaluation questionnaire (SEQ)-major FD score highly correlated with the postprandial fullness/early satiety domain of the Patient Assessment of Gastrointestinal Symptom Severity Index (correlation coefficient r = 0.741, P < 0.001), Nepean Dyspepsia Index-Korean version (NDI-K) (r = 0.839, P < 0.001), and NDI-K quality of life (r = −0.275 to −0.344, P < 0.001). After medical treatment, decrease in the SEQ-typical FD and SEQ-major FD was significantly greater in the responder group than in nonresponder group (P= 0.019 and P = 0.009, respectively). @*Conclusion@#This study suggests that the Korean version of SEQ-DYSPEPSIA has good reliability and validity, and can be a useful PRO measurement tool in patients with FD.

Background/Aims@#Symptom-based subtyping of functional dyspepsia (FD) is used to segregate patients into groups with homogenous pathophysiological mechanisms. This study examined whether subtyping could reflect the duodenal and gastric microinflammation in FD patients. @*Methods@#Twenty-one FD patients without Helicobacter pylori infection were recruited. An endoscopic biopsy was performed in the duodenum 2nd portion, stomach antrum, and body. The eosinophil and mast cell counts per high-power field (×40) were investigated by H&E and c-kit staining, respectively. The degree of inflammatory cell infiltration, atrophy, and intestinal metaplasia was also determined by H&E staining in the stomach. The baseline characteristics and eosinophil and mast cell infiltrations were compared among the three groups (epigastric pain syndrome, postprandial distress syndrome, and overlap). @*Results@#According to the symptom assessment, seven subjects were classified into the epigastric pain syndrome group, 10 into the postprandial syndrome group, and four into the overlap group. The baseline variables were similar in the three groups. Eosinophil infiltration was more prominent in the duodenum than in the stomach. In contrast, mast cell infiltration was similar in the duodenum and stomach. The eosinophil counts in the duodenum were similar in the three groups. The eosinophil counts in the stomach and mast cell counts in the duodenum and stomach were also similar in the three groups. @*Conclusions@#Duodenal eosinophil infiltration was prominent in FD patients, but the eosinophil counts were similar regardless of the symptom-based subtypes of FD. Hence, the current symptom-based subtyping of FD does not reflect duodenal eosinophil and mast cell infiltration.
摘要
Antispasmodics are effective in reducing abdominal pain associated with visceral organs, bloating, and bowel habit changes and are commonly used as “on-demand therapy.” A relatively regular intake of antispasmodics may help patients with functional gastrointestinal disease exacerbation. Irritable bowel syndrome and functional dyspepsia are representative functional gastrointestinal diseases with abdominal pain and bloating as the main symptoms. Most of the clinical data on antispasmodics are obtained from studies on functional gastrointestinal diseases including irritable bowel syndrome. Antispasmodics can be safely used for prolonged periods without serious adverse effects; however, different antispasmodics have different anticholinergic potencies. Antispasmodics with strong anticholinergic effects should be prescribed with caution to patients with glaucoma or prostatic hypertrophy-induced dysuria and to those driving vehicles, operating machinery, or receiving other anticholinergic drugs in combination. Antispasmodics meeting US Food and Drug Administration guidelines for efficacy, those showing relatively consistent efficacy in different trials, and those with prokinetic effects are currently available. Many patients with upper gastrointestinal symptoms have overlapping functional gastrointestinal disorders and may require antispasmodic drugs. Alternatively, tricyclic antidepressant or ramosetron use can be considered in patients with irritable bowel syndrome. This review summarizes the clinical data and characteristics of antispasmodics, particularly those available in South Korea.

Gastroesophageal reflux disease (GERD) is a condition in which gastric contents regurgitate into the esophagus or beyond, resulting in either troublesome symptoms or complications. GERD is heterogeneous in terms of varied manifestations, test findings, and treatment responsiveness. GERD diagnosis can be established with symptomatology, pathology, or physiology. Recently the Lyon consensus defined the “proven GERD” with concrete evidence for reflux, including advanced grade erosive esophagitis (Los Angeles classification grades C and or D esophagitis), long-segment Barrett’s mucosa or peptic strictures on endoscopy or distal esophageal acid exposure time > 6% on 24-hour ambulatory pH-impedance monitoring. However, some Asian researchers have different opinions on whether the same standards should be applied to the Asian population. The prevalence of GERD is increasing in Asia. The present evidence-based guidelines were developed using a systematic review and meta-analysis approach. In GERD with typical symptoms, a proton pump inhibitor test can be recommended as a sensitive, cost-effective, and practical test for GERD diagnosis. Based on a meta-analysis of 19 estimated acid-exposure time values in Asians, the reference range upper limit for esophageal acid exposure time was 3.2% (95% confidence interval 2.7-3.9%) in the Asian countries. Esophageal manometry and novel impedance measurements, including mucosal impedance and a post-reflux swallow-induced peristaltic wave, are promising in discrimination of GERD among different reflux phenotypes, thus increasing its diagnostic yield. We also propose a long-term strategy of evidence-based GERD treatment with proton pump inhibitors and other drugs.

Background@#Implant-based dual-plane augmentation mammoplasty requires accurate separation of the pectoralis major muscle (PMM) at its origins. The authors identified the PMM origins during breast reconstruction surgery with the goal of providing additional information on subpectoral implant insertion for reconstructive or aesthetic purposes. @*Methods@#This study was conducted on 67 patients who underwent breast reconstruction surgery at the breast center of our hospital between November 2016 and June 2018. In total, 34 left and 39 right hemithoraces were examined. The left and right hemithoraces were each divided into 15 zones to determine the percentage of PMM attachments in each zone. The distribution of PMM origins in each zone was examined to identify any statistically significant differences. @*Results@#There were no statistically significant differences in the origins of the PMM between the right and left hemithoraces. The percentage of attachments increased moving from the fourth to the sixth rib and from the lateral to the medial aspect. @*Conclusions@#The anatomical findings of this study could be used as a reference for accurate dissection of the origins of the PMM for the preparation of the subpectoral pocket for subpectoral implant placement.
摘要
Functional dyspepsia (FD) is a chronic upper gastrointestinal (GI) symptom complex that routine diagnostic work-up, such as endoscopy, blood laboratory analysis, or radiological examination, fails to identify a cause. It is highly prevalent in the World population, and its response to the various available therapeutic strategies is only modest because of the heterogenous nature of its pathogenesis. Therefore, FD represents a heavy medical burden for healthcare systems. We constituted a guideline development committee to review the existing guidelines on the management of functional dyspepsia. This committee drafted statements and conducted a systematic review and meta-analysis of various studies, guidelines, and randomized control trials. External review was also conducted by selected experts. These clinical practice guidelines for FD were developed based on evidence recently accumulated with the revised version of FD guidelines released in 2011 by the Korean Society of Neurogastroenterology and Motility. These guidelines apply to adults with chronic symptoms of FD and include the diagnostic role of endoscopy, Helicobacter pylori screening, and systematic review and meta-analyses of the various treatment options for FD (proton pump inhibitors, H. pylori eradication, and tricyclic antidepressants), especially according to the FD subtype. The purpose of these new guidelines is to aid the understanding, diagnosis, and treatment of FD, and the targets of the guidelines are clinicians, healthcare workers at the forefront of patient care, patients, and medical students. The guidelines will continue to be revised and updated periodically.
摘要
Purpose@#In colorectal cancer surgery, it is important to have accurate resection margins. However, it is challenging to localize lesions during laparoscopy. Therefore, to reduce surgical errors, many preoperative localizing methods have been introduced. In this study, we aimed to assess the preoperative feasibility and safety of autologous blood tattooing. @*Methods@#A total of 11 patients underwent preoperative colonoscopic autologous blood tattooing from August 2017 to February 2020. At the start of the surgery, the surgeon assessed the patients for the precision of visibility and other complications such as abscess or spillage. The patients’ characteristics, outcomes, and complications were collected retrospectively. @*Results@#The study comprised 8 men and 3 women, with an average age of 63 years. Ten patients showed precise visibility, and no localization errors were observed during surgery. No complication was observed in all patients. @*Conclusion@#Preoperative autologous blood tattooing is a very useful and safe technique because it has high visibility with no complications. This method does not require additional agents or facilities. A large-scale study will be required to develop standard guidelines.
摘要
Coin batteries are often used in daily life devices and can be easily available. Children can swallow coin batteries, resulting in the need to go to hospital, but this is rare in adults. Adults generally eliminate the swallowed coin battery from the digestive system, unless they have congenital structural abnormalities of the digestive system or complications, such as postoperative stenosis. In this case, a 31-year-old man swallowed three coin batteries, approximately 0.4 cm in diameter emergent endoscopy was unable to find any batteries embedded in the ingested food. An attempt was made to rinse out the batteries by bowel preparation. During the hospital stay, the patient complained of acute abdominal pain and fever. In the abdominal CT scan, impaction of the coin battery into the appendix was confirmed. The patient underwent a laparoscopic appendectomy to prevent appendiceal perforation.

BACKGROUND/AIMS: An incomplete virological response has been observed to tenofovir dipivoxil fumarate (TDF) in nucleos(t)ide analogue (NA)-experienced chronic hepatitis B (CHB) patients. This study investigated the efficacy of TDF in NA-naïve CHB patients 96 weeks after treatment. METHODS: CHB patients treated with TDF were enrolled retrospectively between November 2012 and January 2016. We assessed virological and biochemical parameters. RESULTS: The study enrolled 179 NA-naïve patients with a median follow-up duration of 59.6 weeks. The serum hepatitis B virus (HBV) DNA level decreased significantly during treatment. The complete virological response (CVR) rate was 83.21% at week 96. In univariate analyses, the predictors of a CVR at 96 weeks were the baseline HBV DNA level (CVR vs. no-CVR, HBV DNA log10 mean value 7.34 vs. 7.86, 95% confidential interval [CI]: -7.89 to -7.37; p < 0.001) and male sex (CVR vs. no-CVR, 49.1% vs. 81.3%, odds ratio [OR] 0.22, 95% CI: 0.06 to 0.87; p = 0.025). In the multivariate analysis, male sex predicted a CVR at week 96. The CVR was significantly lower in males than in females (OR 0.12, 95% CI: 0.02 to 0.96; p = 0.046). CONCLUSIONS: TDF was effective for treating CHB for more than 2 years in NA-naïve patients.

Functional dyspepsia is one of the most common bowel disorders as prevalent of 7.7% Korean population. The cardinal manifestations include bothersome postprandial fullness, early satiation, epigastric burning or pain. These features are chronic and should be presented recurrently with no other compatible organic disease to explain the symptoms. Even though it is not life-shortening, functional dyspepsia usually make the health-related quality of life worse especially if other functional bowel disorder coexist. The coexistence of functional bowel disorders is called as 'overlap syndrome'. Anxiety, somatization and insomnia is more prevalent in overlap syndrome compared with sole functional bowel disorder. Therefore, it is worthwhile that physician interviews and elucidates whether the dyspeptic patient had other kinds of functional bowel disorders, and manages the underlying psychotic pathology. Placebo effect is large in functional dyspepsia, and there is only four kinds of prokinetics that is proven to be superior to placebo. Adverse events relating prolonged administration of prokinetics sometimes fatal or irreversible, physician willing to describe prokinetics should be familiar to the possible adverse effects and the relating risk factors. Pathologic acid reflux is not uncommon in functional dyspepsia, and acid-suppressant is equivalent to the prokientics in most of dyspeptic patients.
