Risk Factors for Lymph Node Metastasis and Oncologic Outcomes in Small Rectal Neuroendocrine Tumors with Lymphovascular Invasion

Background/Aims@#Small rectal neuroendocrine tumors (NETs) are often managed with local resection (endoscopic or transanal excision) owing to their low risk of metastasis and recurrence. However, the clinical significance of lymphovascular invasion in resected specimens remains controversial. In this study, we aimed to analyze the frequency of and risk factors for lymph node metastasis proven by histopathologic examination after radical resection. @*Methods@#We retrospectively reviewed the records of 750 patients diagnosed with a rectal NET at four academic medical centers in South Korea between 2001 and 2019. The frequency of histopathologically proven lymph node metastasis and the associated risk factors were analyzed for small tumors (≤1.5 cm) with lymphovascular invasion. @*Results@#Among 750 patients, 75 had a small tumor (≤1.5 cm) with lymphovascular invasion, of whom 31 patients underwent endoscopic resection only and 44 patients underwent additional radical surgery. Among the 41 patients who underwent surgery and had available data, the rate of regional lymph node metastasis was 48.8% (20/41). In multivariate analysis, the Ki-67 index (odds ratio, 6.279; 95% confidence interval, 1.212 to 32.528; p=0.029) was an independent risk factor for lymph node metastasis. During the mean follow-up period of 37.7 months, only one case of recurrence was detected in the surgery group. The overall survival was not significantly different between radical resection and local resection (p=0.332). @*Conclusions@#Rectal NETs with lymphovascular invasion showed a significantly high rate of regional lymph node metastasis despite their small size (≤1.5 cm).

Efficacy and Safety of Rebamipide versus Its New Formulation, AD-203, in Patients with Erosive Gastritis: A Randomized, DoubleBlind, Active Control, Noninferiority, Multicenter, Phase 3 Study

Background/Aims@#The mucoprotective drug rebamipide is used to treat gastritis and peptic ulcers. We compared the efficacy of Mucosta Ⓡ (rebamipide 100 mg) and its new formulation, AD-203 (rebamipide 150 mg), in treating erosive gastritis. @*Methods@#This double-blind, active control, noninferiority, multicenter, phase 3 clinical trial randomly assigned 475 patients with endoscopically proven erosive gastritis to two groups: AD-203 twice daily or Mucosta Ⓡ thrice daily for 2 weeks. The intention-to-treat (ITT) analysis included 454 patients (AD-203, n=229; Mucosta Ⓡ , n=225), and the per-protocol (PP) analysis included 439 patients (AD-203, n=224; Mucosta Ⓡ , n=215). The posttreatment assessments included the primary (erosion improvement rate) and secondary endpoints (erosion and edema cure rates; improvement rates of redness, hemorrhage, and gastrointestinal symptoms). Drug-related adverse events were evaluated. @*Results@#According to the ITT analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.7% and 43.8%, respectively. According to the PP analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.3% and 43.7%, respectively. The one-sided 97.5% lower limit for the improvement rate difference between the study groups was −4.01% (95% confidence interval [CI], –13.09% to 5.06%) in the ITT analysis and −4.44% (95% CI, –13.65% to 4.78%) in the PP analysis. The groups did not significantly differ in the secondary endpoints in either analysis. Twenty-four AD-203-treated and 20 Mucosta Ⓡ -treated patients reported adverse events but no serious adverse drug reactions; both groups presented similar adverse event rates. @*Conclusions@#The new formulation of rebamipide 150 mg (AD-203) twice daily was not inferior to rebamipide 100 mg (Mucosta Ⓡ ) thrice daily. Both formulations showed a similar efficacy in treating erosive gastritis.

Postoperative Clinical Outcomes of Colonic Stent Placement as Bridge-to-surgery vs. Emergency Surgery in Left-sided Malignant Colonic Obstruction / 대한소화기암학회지

Background/Aims@#Colonic stenting as a bridge to elective surgery is an alternative for emergency surgery in patients with acute malignant colonic obstruction. However, since its benefits are uncertain, we aimed to establish whether it has better clinical outcomes. @*Methods@#The patients with acute malignant left-sided colon obstruction enrolled from January 2009 to December 2018 in National Health Insurance Service Ilsan Hospital. The patients were enrolled to undergo colonic stenting as a bridge to elective surgery or emergency surgery. The following oncological outcomes were assessed: incidence of complete remission, disease progression, local recurrence, and systemic recurrence. @*Results@#Out of 40 patients, 33 received self-expanding metallic stent (SEMS) as a bridge-tosurgery, and 7 underwent emergency surgery. More stoma was made in case of emergency surgery with statistical significance (p < 0.001). There were no significant differences in complete remission rate in curable left-sided malignant colonic obstruction between SEMS as a bridgeto-surgery and emergency surgery. Complete remission was achieved for 3 patients (42.9%) in the non-stent group and 27 patients (81.8%) in the stent group. There was no statistically significant difference in oncologic outcomes between the two groups (p = 0.069). According to multi-variate analysis, advanced TNM stage, Adjuvant chemotherapy, and SEMS bridge-tosurgery were significantly associated with disease-free survival. Disease-free survival rate differed significantly between the two groups (p = 0.024). @*Conclusions@#SEMS as a bridge-to-surgery might be an effective strategy and reduce stoma formation in acute malignant left-sided colon obstruction.

Risk for metabolic syndrome in the population with visceral fat area measured by bioelectrical impedance analysis

Background/Aims@#To investigate whether visceral fat area (VFA) measured by bioelectric impedance analysis (BIA) was associated with metabolic syndrome in subjects with and without obesity. @*Methods@#A total 23,202 participants who underwent medical check-ups were assessed. Participants were stratified by body mass index (BMI) and VFA. We evaluated six different groups for metabolic syndrome: Group 1 (normal weight and low VFA), Group 2 (normal weight and high VFA), Group 3 (overweight and low VFA), Group 4 (overweight and high VFA), Group 5 (obesity and low VFA), and Group 6 (obesity and high VFA). @*Results@#Metabolic syndrome traits and metabolic syndrome were significantly more prevalent in the high-VFA (≥ 100 cm2 ) subgroup in each BMI group. Adjusted logistic regression analyses revealed that the odds ratio for metabolic syndrome compared with Group 1 was the highest in Group 6 (24.53; 95% confidence interval [CI], 21.77 to 27.64). Notably, the odds ratio of Group 2 was higher than that of Group 3 (2.92; 95% CI, 2.30 to 3.69 vs. 2.57; 95% CI, 2.23 to 2.97). @*Conclusions@#Our study demonstrates that the combination of BMI assessment and VFA determination by BIA may be a useful method for predicting the risk of metabolic syndrome. The VFA by BIA may be a useful target for interventions to improve metabolic syndrome.

Effect of Gastric Cancer Screening on Patients with Gastric Cancer:A Nationwide Population-based Study / 대한소화기암학회지

Background@#This study was performed to evaluate the effect of gastric cancer screening through analysis of screening-related data. @*Methods@#We investigated claims data of gastric cancer from 2009 to 2015. We evaluated whether the screening was performed to prior to registration as patients with gastric cancer. The effect of gastric cancer screening was also analyzed by gender. @*Results@#We collected total 196,293 patients with gastric cancer. 74% of them had previous experience of gastric cancer screening. In patients with screening, early gastric cancer was 33.4% and advanced gastric cancer was 17.3%. 22,548 (15.5%) patients were diagnosed with gastric cancer within 2 years after screening. In the case of patients without screening, early gastric cancer was 15.1% and advanced gastric cancer was 25.3%. In case of men, 76% of them confirmed gastric cancer through screening, and 70.2% of women confirmed the gastric cancer. In both men and women, the rate of early gastric cancer was higher among those with screening than those without screening. @*Conclusion@#In this study, we were able to indirectly confirm the stage shift of gastric cancer screening. However, within 2 years after screening, not a few patients with gastric cancer were diagnosed. Therefore, more studies are warranted to in the future.

The Effect of Psychological Factors on Postoperative Pain in Gastric Tumor Patients after Endoscopic Submucosal Dissection / 정신신체의학

OBJECTIVES: Since pain in cancer patients is an important factor that greatly affects the quality of life and prognosis, many attempts have been actively made to reduce the pain. Despite continuous effort on reducing pain after Endoscopic submucosal dissection (ESD), research has not been done on psychological factors as much as on biological factors affecting pain. The objective of this study is to investigate the psychological factors affecting postoperative pain in gastric tumor patients who underwent gastric ESD. METHODS: 91 gastric tumor patients who visited National Health Service Ilsan Hospital in Korean between May 2015 and June 2016, and received ESD were evaluated. Baseline characteristics including sociodemographic factors, anxiety, depression, and resilience were evaluated before the procedure. Multivariate logistic regression was done to analyze factors affecting postoperative pain. RESULTS: The group with high postoperative pain showed lower alcohol consumption and higher depressive symptom scores than the group with low postoperative pain. Also, the group with high postoperative pain showed lower total resilience score with lower subtotal scores in self-control and positive item. Multivariate logistic regression analysis of the postoperative pain showed that patients with lower score in self-control of resilience [odd ratio (OR), 0.911 ; 95% CI, 0.854–0.971, p=0.004) reported more pain after ESD. CONCLUSIONS: This study showed that patients with lower self-control ability of resilience felt more pain after ESD. Among the psychological factors evaluated in this study, resilience of an individual seems to have effect on pain.

Real World Experience of Telbivudine Versus Entecavir in Patients with Chronic Hepatitis B, Including Long-Term Outcomes after Treatment Modification

PURPOSE: To estimate long-term outcomes after treatment modification in patients with chronic hepatitis B (CHB) treated with entecavir (ETV) and telbivudine (LdT). MATERIALS AND METHODS: The study enrolled 131 nucleos(t)ide analogue (NA)-naïve CHB patients treated with ETV or LdT. During the 3-year study, NA treatment history including the incidence, the type of treatment modification, reasons for the modification, and overall complete virologic response (CVR) rate were retrospectively evaluated using the patients' medical records. RESULTS: Among the 131 patients, 84 and 47 were initially treated with ETV and LdT, respectively. During the course of 3-year study, 82 patients in the ETV group (97.6%) maintained initial treatment whereas only 19 in the LdT group (40.4%). In the LdT group, 26 patients (92.9%) switched to another NA and another NA was added in 2 (7.1%) patients. An assessment of the CVR rate at 3 years, including treatment modification, showed that 89.3% and 95.7% of patients in the ETV and LdT groups, respectively, had undetectable serum hepatitis B virus DNA levels (p=0.329). Among LdT patients with treatment modification, the cumulative incidence rate of a CVR for rescue therapy was significantly higher in the tenofovir than in the ETV group (p=0.009). CONCLUSION: During the 3-year study, there were no significant differences in the CVR between the ETV and LdT groups if appropriate rescue therapy was considered.

Entecavir to Telbivudine Switch Therapy in Entecavir-Treated Patients with Undetectable Hepatitis B Viral DNA

PURPOSE: This study examined 2-year outcome of consecutive therapy using entecavir (ETV) followed by telbivudine (LdT) in subjects with undetectable hepatitis B virus (HBV) DNA level and normal alanine aminotransferase level after the initial 6 months of ETV treatment. MATERIALS AND METHODS: Sixty subjects were randomized to continue with ETV or switch to LdT. Significant difference in baseline characteristics was not found between the two groups. Persistent HBV DNA level of 20–60 IU/mL in three consecutive samples collected three months apart or singly measured HBV DNA level of >60 IU/mL was defined as virological rebound. RESULTS: During 96 weeks of follow-up, all subjects of the ETV-only group (n=30) resulted in undetectable HBV DNA level. On the other hand, 83.3% (n=25) of the LdT-switched group showed treatment success. Virological rebound time varied from week 24 to 84 after switching to LdT. HBV DNA level was 180 to 2940 IU/mL at rebound time. All subjects with virological rebound (n=5) showed drug-resistant mutation: three had mutation rtM204I, and two had mutation rtM204V. Consecutive treatment using ETV followed by LdT showed virological rebound in 16.7% of subjects during 96 weeks of follow-up. HBV DNA negativity during initial ETV therapy could not be achieved in patients who switched to LdT. CONCLUSION: Consecutive treatment using ETV followed by lamivudine was ineffective for treating chronic hepatitis B. LdT was found as a more potent antiviral agent than lamivudine. However, this conclusion requires larger-scale, long-term prospective reviews of the treatment effects of ETV-LdT switch therapy.

Clinical Characteristics of Patients with Untreated Achalasia

BACKGROUND/AIMS: Patients with untreated achalasia frequently complain of heartburn and regurgitation. The diagnosis of achalasia might be delayed because these symptoms are misinterpreted as gastroesophageal reflux. We aim to evaluate the clinical, radiologic, and manometric findings in patient with untreated achalasia. METHODS: The records of patients diagnosed with primary achalasia between July 2004 and January 2012 at Gangnam Severance Hospital, Seoul, Korea were evaluated. We reviewed their clinical history and the findings of barium esophagogram, upper gastrointestinal endoscopy, and esophageal transit scintigraphy. We also compared the clinical, radiologic, and manometric findings of patients according to heartburn symptoms and proton pump inhibitor use. RESULTS: Our study included a total of 64 patients with a median age of 44.5 (interquartile range, 31.5–54.0). The median duration of symptoms was 23.5 (interquartile range, 5.3–57.0) months. Sixty-four patients (100%) had dysphagia, 49 (76.6%) had regurgitation, 35 (54.7%) had chest pain, and 38 (59.4%) had heartburn. Typical clinical features of gastroesophageal reflux disease (GERD) such as regurgitation, heartburn, and chest pain were observed in more than 50% of achalasia patients. Proton pump inhibitors were prescribed for 16 patients (25%) on the assumption that they had GERD. Patients with heartburn were more likely to experience weight loss (P = 0.009), regurgitation (P = 0.001), or chest pain (P = 0.019). CONCLUSIONS: Heartburn, regurgitation, and chest pain were commonly observed in patients with untreated achalasia. Therefore, these findings suggest that achalasia should be suspected in patients with refractory GERD.

A Case of Postfundoplication Dysphagia without Symptomatic Improvement after Endoscopic Dilatation

Laparoscopic fundoplication is a treatment option for gastroesophageal reflux disease refractory to medical treatment. When deciding whether or not to undergo surgery, patients with refractory gastroesophageal reflux disease and esophageal motility disorder need to fully understand the operative procedure, postoperative complications, and residual symptoms such as dysphagia, globus sensation, and recurrence of reflux. Herein, we report a case of a patient diagnosed with gastroesophageal reflux disease and aperistalsis who underwent Nissen (total, 360degrees) fundoplication after lack of response to medical treatment and subsequently underwent pneumatic dilatation due to unrelieved postoperative dysphagia and globus sensation.

Effects of GC7101, a Novel Prokinetic Agent on Gastric Motor Function: Ex Vivo Study

BACKGROUND/AIMS: GC7101, an extract of Lonicera Flos, is a novel developing drug for reflux esophagitis and functional dyspepsia. However, the drug's exact pharmacological mechanism of action remains unclear. This study assessed the effects of GC7101 on gastrointestinal (GI) motor function. METHODS: We used male guinea pigs to evaluate the effects of GC7101 on GI motility. The contraction of antral circular muscle in the presence of different doses of GC7101 was measured in a tissue bath. The prokinetic effects of GC7101 were tested using the charcoal transit assay from the pylorus to the most distal point of migration of charcoal mixture. To clarify the mechanism of action of GC7101, atropine, dopamine and the selective 5-hydroxytryptamine 4 receptor antagonist, GR113808 were used. RESULTS: The maximal amplitude of circular muscle contraction was induced by 5 mg mL(-1) GC7101. The area under the curve of contraction was significantly increased at 5 mg mL(-1) GC7101. Addition of 10(-6) M atropine, 10(-8) M dopamine or 10(-7) M GR 113808 to GC7101 5 mg mL(-1) decreased the amplitude and area under curve compared to GC7101 5 mg mL(-1) alone. GC7101 accelerated GI transit in a dose dependent manner except 100 mg kg(-1). Delayed GI transit caused by atropine, dopamine and GR 113808 was restored by GC7101 50 mg kg(-1). CONCLUSIONS: GC7101, an extract of Lonicera Flos, exerts a gastric prokinetic effect in guinea pig through cholinergic, antidopaminergic and serotonergic mechanisms. Therefore, GC7101 might be a novel drug for the treatment of functional dyspepsia.

Diagnosis and Treatment of Constipation / 대한내과학회지

Constipation is a common condition affecting approximately 16.5% of population in Korea. Evaluation of constipation should be done with a history and physical examination at first. In patients with alarm sign, blood test, radiography or colonoscopy should be considered. Additionally, for defining the pathophysiology and treatment of severe constipation, physiologic studies are needed. Treatment of constipation based on the pathophysiology is generally successful. Exercise and fiber are helpful in some patients with constipation. The laxative including osmotic agent, stimulant laxatives and stool softer have been shown to be more effective than placebo at relieving symptoms of constipation. Traditional laxatives are not tolerated and are not effective in all patients with constipation. Promising drug classes, new enterokinetic agents such as 5-hydroxytyptamine-4 receptor agonists and chloride channel activators could be effective in patients with severe constipation. Biofeedback could relieve symptoms in selected patients with pelvic floor dysfunction and severe constipation. Surgical treatment could be helpful in carefully selected patients with refractory constipation.

Helicobacter pylori Infection is Associated with Elevated Low Density Lipoprotein Cholesterol Levels in Elderly Koreans

This study was conducted to investigate the association between Helicobacter pylori (H. pylori) infection and the lipid profile among elderly Koreans. A total of 462 subjects (mean age 66.2 +/- 7.6 yr, 84% males) who underwent health check-up were investigated. Each subject underwent gastroduodenoscopy with gastric mucosal biopsy, and H. pylori infection was determined by histopathological examination using the updated Sydney System score. The presence of H. pylori infection was significantly associated with the elevated serum levels of total cholesterol and low density lipoprotein (LDL) cholesterol (P 0.05 for each). After controlling confounders, multiple logistic regression analysis showed that the odds ratio of H. pylori infection for high LDL cholesterol level (> 140 mg/dL) was 3.113 (95% confidence interval, 1.364-7.018; P = 0.007). There were no significant associations between the presence of H. pylori infection and elevated total cholesterol levels (> 200 mg/dL) in this model (P = 0.586). The results of this study demonstrate that H. pylori infection is associated with the elevated serum LDL cholesterol levels in elderly Koreans, supporting the hypothesis that H. pylori plays a role in promoting atherosclerosis by modifying lipid metabolism.

Laboratory Confirmatory Rate of Pandemic Influenza (H1N1 2009) Virus in Korean Households with Index Case / 감염과화학요법

BACKGROUND: Influenza transmission in households a subject of renewed interest especially in pandemic situation. We performed this study to investigate the laboratory-confirmatory rate in household contacts with index cases of pandemic influenza (H1N1 2009). MATERIALS AND METHODS: For three months from 1 September and 29 November 2009, people who had a history of close contact with confirmed cases of pandemic influenza (index case) were recruited. The information on the study participants was collected using a standardized questionnaire. Presence of the pandemic influenza (H1N1 2009) infection was confirmed by real-time reverse-transcription polymerase chain reaction (RT-PCR). RESULTS: A total of 113 index cases and 141 household contacts were investigated. One hundred and four index cases (92.0%) were younger than 20 years. The median age of household contacts was 40 years. Twenty eight household contacts (19.8%) had acute respiratory illness (ARI). Overall, 10.6% of enrolled household contacts were positive in RT-PCR for pandemic influenza (H1N1 2009). The positive rate of household contacts with ARI was 25.0% and it was 7.1% in household contacts without ARI. The positive rate was significantly higher in children and young adults under 30 years (28.3%) compared with that in household contacts older than 30 years (8.3%). CONCLUSIONS: This results showed a significant role of mild symptomatic or asymptomatic pandemic influenza (H1N1 2009) patients as a virus carriers in households.

A Case of Pneumothorax Caused by Cystic Lung Metastasis of Angiosarcoma / 결핵및호흡기질환

Angiosarcoma is a rare but highly malignant tumorthat usually arises in the scalp or face of elderly males. Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp.

Localized Fibrosing Mediastinitis with Superior Vena Caval(SVC) Syndrome / 결핵및호흡기질환

Fibrosing mediastinitis is a rare disease that is characterized by the proliferation of dense fibrous tissue of the mediastinum. The pathogenesis of fibrosing mediastinitis is unknown in most cases. However, histoplasmosis, tuberculosis, autoimmune disease, radiation therapy, and other idiopathic fibroinflammatory diseases have been implicated in some cases. Most clinical features are related to an obstruction or compression of the mediastinal structure. Fibrosing mediastinitis is often progressive and occurs diffusely throughout the mediastinum. We encountered a case of fibrosing mediastinitis of a very focal lesion without evidence of mediastinal involvement. The condition was confirmed by biopsy and graft bypass surgery was performed because of SVC syndrome.

Applicability of American and European Spirometry Repeatability Criteria to Korean Adults / 결핵및호흡기질환

BACKGROUND: The objective of this study was to evaluate the clinical applicability of the repeatability criteria recommended by the American Thoracic Society/European Respiratory Society (ATS/ERS) spirometry guidelines and to determine which factors affect the repeatability of spirometry in Korean adults. METHODS: We reviewed the spirometry data of 4,663 Korean adults from the Korean National Health and Nutritional Examination Survey (KNHANES) Chronic Obstructive Pulmonary Disease Cohort (COPD cohort) and the Community-based Cohort Study VI-Fishing village/Islands (community cohort). We measured the anthropometric factors and differences between the highest and second-highest FVC (dFVC) and FEV1 (dFEV1) from prebronchodilator spirometry. Analyses included the distribution of dFVC and dFEV1, comparison of the values meeting the 1994 ATS repeatability criteria with the values meeting the 2005 ATS/ERS repeatability criteria, and the performance of linear regression for evaluating the influence of subject characteristics and the change of criteria on the spirometric variability. RESULTS: About 95% of subjects were able to reproduce FVC and FEV1 within 150 ml. The KNHANES based on the 1994 ATS guidelines showed poorer repeatability than the COPD cohort and community cohort based on the 2005 ATS/ERS guidelines. Demographic and anthropometric factors had little effect on repeatability, explaining only 0.5 to 3%. CONCLUSION: We conclude that the new spirometry repeatability criteria recommended by the 2005 ATS/ERS guidelines is also applicable to Korean adults. The repeatability of spirometry depends little on individual characteristics when an experienced technician performs testing. Therefore, we suggest that sustained efforts for public awareness of new repeatability criteria, quality control of spirograms, and education of personnel are needed for reliable spirometric results.

A Case of Brucellar Spondylitis with Multiple Spine Involvement / 감염과화학요법

Brucellosis, a zoonosis with world wide distribution, is a systemic infection that affects several organs and has protean presentation. Although spondylitis is universally the most common complication of brucellosis and difficult to treat, there is no consensus on the preferred combination of antibiotics use. The authors report a case of a 58-year-old male patient with brucellar spondylitis involving several vertebrae. Diagnosis was made by positive blood culture and magnetic resonance imaging. The authors use a combination method of doxycycline, ciprofloxacin and streptomycin for a period of 3 months. The systemic symptoms were improved after treatment.
