RESUMEN
BACKGROUND: Recently, a simple tailored therapy based on clarithromycin resistance has been implemented as Helicobacter pylori (H. pylori) eradication therapy. Nonetheless, despite the tailored therapy and frequent adverse events, studies on treatment period are lacking. This study aimed to compare the H. pylori eradication rates of 7-day and 14-day tailored therapy regimens according to clarithromycin resistance. MATERIALS AND METHODS: This multicenter, prospective, randomized, noninferiority trial enrolled H. pylori-positive patients who were randomly assigned to 7-day and 14-day regimen groups, depending on the presence or absence of clarithromycin resistance by 23S rRNA gene point mutations. Standard triple therapy (STT) (20 mg rabeprazole, 1 g amoxicillin, and 500 mg clarithromycin twice daily) or bismuth quadruple therapy (BQT) (20 mg rabeprazole twice daily, 500 mg metronidazole thrice daily, 120 mg bismuth four times daily, and 500 mg tetracycline four times daily) was assigned by clarithromycin resistance. Eradication rates and adverse events were evaluated. RESULTS: A total of 314 and 278 patients were included in the intention-to-treat (ITT) and per-protocol (PP) analyses, respectively; however, 31 patients were lost to follow-up, whereas five patients violated the protocol. Both the 7-day and 14-day regimens showed similar eradication rates in the ITT (7-day vs. 14-day: 78.3% vs. 78.3%, p > 0.99) and PP (87.9% vs. 89.1%, p = 0.851) analyses. Non-inferiority was confirmed (p < 0.025). A subgroup analysis according to clarithromycin resistance (clarithromycin resistance rate: 28.7%) revealed no significant difference in eradication rates between the 7-day and 14-day STT (90.0% vs. 90.1%, p > 0.99) and BQT (82.5% vs. 86.5%, p = 0.757). Furthermore, adverse events did not significantly differ between the two groups. CONCLUSIONS: The 7-day triple and quadruple therapy according to clarithromycin resistance showed similar eradication rates, as compared to the 14-day therapy.

RATIONALE: Colorectal cancer is the third most common cancer diagnosed worldwide. At the time of diagnosis of colorectal cancer, one of the most common metastatic sites is liver. Gastric metastasis from colorectal origin is rare. Moreover, a direct invasion of the stomach, by hepatic metastasis from colorectal cancer, is particularly uncommon. PATIENT CONCERNS: A 56-year-old male patient with hematochezia was referred to our hospital. DIAGNOSIS: The patient was diagnosed with unresectable colorectal cancer because of the presence ofâ >10 metastases involving both lobes of the liver. INTERVENTIONS AND OUTCOMES: After chemotherapy, the metastatic nodules in the liver nearly disappeared, except for a small nodule in segment VI. The patient underwent a radiofrequency ablation for the single lesion in the liver and laparoscopic low-anterior-resection for the primary tumor. Despite receiving various chemotherapy regimens, he experienced 6 recurrences, leading to 5 hepatectomies including a right hemi-hepatectomy, 1 pulmonary wedge resection, and 2 courses of radiation treatments. Lastly, a metastatic lesion in the liver was observed with invasion into the stomach. Subsequently, gastric wedge resection with resection of segments III and IV of the liver was performed. Direct invasion of the liver metastases into the stomach was confirmed histologically. LESSONS: The patient is still alive, with a good quality of life, even after more than 8 years since the initial diagnosis. In the last instance of metastatic recurrence, direct invasion from the liver metastases into the stomach was observed, which is rare, and there are currently no reported cases.

Background/Aims: The efficacy of concurrent chemoradiotherapy (CCRT) or esophagectomy for locally advanced esophageal squamous cell carcinoma (ESCC) is unclear. This study compared the survival and recurrence of patients with locally advanced ESCC after definitive CCRT and surgery. Methods: A retrospective study was conducted on patients with locally advanced ESCC who underwent CCRT or esophagectomy at Kosin University Gospel Hospital from January 2010 to December 2016. The patients' baseline characteristics, pathology, recurrence rate, and three-year/five-year overall survival were obtained. Results: This study evaluated ESCC patients with cT1-T2, N+ or cT3-T4, or N, who were treated by definitive CCRT (n=14) or esophagectomy (n=32). No significant difference was noted between the two groups, except for the location of the cancer and performance state. The respective three- and five-year overall survival rates were 30.8% and 23.1% in the CCRT group and 40.2% and 22.5% in the esophagectomy group (p=0.685). In the CCRT group, three patients (21.4%) had a complete response, and two (66.7%) had a recurrence. In the esophagectomy group, an R0 resection was achieved in 28 (87.5%) patients, and a recurrence occurred in 18 (64.3%). The median disease-free survival in the CCRT and esophagectomy groups was 14 and 17 months, respectively (p=0.882). Conclusions: These results showed no significant difference in survival between the definitive CCRT and surgery as the initial treatment. Nevertheless, larger prospective studies will be needed because of the retrospective nature and small number of patients in this study.

Achalasia is an esophageal motility disorder characterized by loss of esophageal peristalsis and impaired relaxation of the lower esophageal sphincter. Patients with achalasia often complain of persistent symptoms for several years before diagnosis. On the other hand, achalasia diagnosed as a sudden esophageal food impaction is uncommon, and no report has been issued on the diagnosis and successful treatment of achalasia in a 95-year-old patient. We report a case of achalasia diagnosed by high-resolution esophageal manometry and timed barium esophagography after food material removal by endoscopy in a 95-year-old woman who visited the hospital due to sudden esophageal food impaction and was successfully treated by endoscopic balloon dilatation.

Background/Aims: H2 receptor antagonists (H2RA) have been used to treat gastritis by inhibiting gastric acid. Proton pump inhibitors (PPIs) are more potent acid suppressants than H2RA. However, the efficacy and safety of low-dose PPI for treating gastritis remain unclear. The aim was to investigate the efficacy and safety of low-dose PPI for treating gastritis. Methods: A double-blind, noninferiority, multicenter, phase 3 clinical trial randomly assigned 476 patients with endoscopic erosive gastritis to a group using esomeprazole 10 mg (DW1903) daily and a group using famotidine 20 mg (DW1903R1) daily for 2 weeks. The full-analysis set included 319 patients (DW1903, n=159; DW1903R1, n=160) and the per-protocol set included 298 patients (DW1903, n=147; DW1903R1, n=151). The primary endpoint (erosion improvement rate) and secondary endpoint (erosion and edema cure rates, improvement rates of hemorrhage, erythema, and symptoms) were assessed after the treatment. Adverse events were compared. Results: According to the full-analysis set, the erosion improvement rates in the DW1903 and DW1903R1 groups were 59.8% and 58.8%, respectively. According to the per-protocol analysis, the erosion improvement rates in the DW1903 and DW1903R1 groups were 61.9% and 59.6%, respectively. Secondary endpoints were not significantly different between two groups except that the hemorrhagic improvement rate was higher in DW1903 with statistical tendency. The number of adverse events were not statistically different. Conclusions: DW1903 of a low-dose PPI was not inferior to DW1903R1 of H2RA. Thus, lowdose PPI can be a novel option for treating gastritis (ClinicalTrials.gov Identifier: NCT05163756).

BACKGROUND: Proton-pump inhibitors (PPIs) are the most effective drugs for treating acid-related disorders. However, once-daily dosing with conventional PPIs fail to fully control acid secretion over 24 h. This study aimed to compare the efficacy and safety of HIP1601 (dual delayed-release esomeprazole) and HGP1705 (delayed-release esomeprazole) in patients with erosive esophagitis (EE). METHODS: We enrolled 213 patients with EE randomized in a 1:1 ratio to receive 40 mg HIP1601 (n = 107) or HGP1705 (n = 106) once daily for 4 or 8 weeks. The primary endpoint was the EE healing rate, confirmed by endoscopy up to week 8. GERD-related symptoms and treatment-emergent adverse events were compared between both groups. RESULTS: By week 8, the estimated healing rates of EE were 97.8% and 96.8% in the HIP1601 and HGP1705 groups, respectively, with a 95% confidence interval of -4.7 to 7.2. After 4 or 8 weeks of treatment, the EE healing rate at week 4, complete resolution rate of symptoms, time to sustained resolution of symptoms, and number of rescue medications used were similar in both groups. The proportion of heartburn- and acid regurgitation-free nights by week 4 were higher in the HIP1601 group compared to the HGP1705 group, but the difference did not reach clinical significance (87.7% vs. 85.8%, P = 0.514, 87.5% vs. 85.8%, P = 0.774). The number of adverse events did not differ significantly between the two groups. CONCLUSIONS: The efficacy and safety of HIP1601 40 mg were comparable to those of HGP1705 40 mg for the treatment of EE and symptomatic improvement of GERD.

Achalasia, a rare motility disorder of the esophagus, is generally accepted as a premalignant disorder. This paper presents the case of a 72-year-old male with achalasia and synchronous superficial esophageal cancer who experienced dysphagia symptoms for five years. As achalasia is associated with an increased risk of esophageal cancer, both can be treated simultaneously if detected at the time of diagnosis. Achalasia and synchronous esophageal cancer are rarely detected and treated endoscopically. This paper reports a case of concurrent successful treatment.

Colorectal strictures are uncommon in patients with ulcerative colitis (UC). An extranodal marginal zone B-cell lymphoma of mucosa- associated lymphoid tissue (MALT) lymphoma is rarely involved in the colon but may be associated with inflammatory bowel diseases. A 41-year-old female with a six-year history of UC presented with a severe stricture of the sigmoid colon that prevented the passage of a colonoscope. A histological examination revealed non-specific inflammation and fibrosis without dysplasia or cancer. Despite conventional treatment, including mesalazine and azathioprine for one year after that visit, the stricture persisted. In addition, diffuse, edematous exudative inflammation and multiple shallow ulcers were observed in the distal rectum, revealing a MALT lymphoma testing positive for CD20, CD43, CD5, and Bcl-2, but negative for CD3, CD10, CD23, and cyclin-D1. Four weekly doses of rituximab were administered. Follow-up colonoscopy performed one month after treatment revealed slight improvement in the rectal lesion without remnant histological evidence of a MALT lymphoma. In addition, the stricture showed marked improvement, and the colonoscope could pass easily through the stricture site. This is the first case report on an improvement of a severe sigmoid colon stricture in a patient with UC after rituximab treatment for a concomitant rectal MALT lymphoma.

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 non-inferiority 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.
RESUMEN
Background/Aims: Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal disorder that typically requires long-term maintenance therapy. However, little is known about patient preferences and satisfaction and real-world prescription patterns regarding maintenance therapy for GERD. Methods: This observational, cross-sectional, multicenter study involved patients from 18 referral hospitals in Korea. We surveyed patients who had been prescribed proton pump inhibitors (PPIs) for GERD for at least 90 days with a minimum follow-up duration of 1 year. The main outcome was overall patient satisfaction with different maintenance therapy modalities. Results: A total of 197 patients were enrolled. Overall patient satisfaction, patient preferences, and GERD health-related quality of life scores did not significantly differ among the maintenance therapy modality groups. However, the on-demand therapy group experienced a significantly longer disease duration than the continuous therapy group. The continuous therapy group demonstrated a lower level of awareness of potential adverse effects associated with PPIs than the on-demand therapy group but received higher doses of PPIs than the on-demand therapy group. The prescribed doses of PPIs also varied based on the phenotype of GERD, with higher doses prescribed for non-erosive reflux disease than erosive reflux disease. Conclusion: Although overall patient satisfaction did not significantly differ among the different PPI maintenance therapy modality groups, awareness of potential adverse effects was significantly different between the on-demand and continuous therapy groups.
RESUMEN
BACKGROUND: Many studies have reported the use of simethicone before colonoscopy removes bubbles. However, guidelines weakly recommend simethicone administration before colonoscopy. The present study aimed to confirm the advantages of taking simethicone and determine the appropriate time for taking simethicone. METHODS: We randomly assigned patients to the following 5 groups according to the administration time: 4 groups were divided based on 2 parameters (the day before and on the day of colonoscopy and before and after bowel cleansing) and the remaining group was the control group. We compared bubble score (BS), number of simethicone solution irrigations when visually obscured, satisfaction score of the endoscopist, insertion time. RESULTS: A total of 204 patients were included in the study. There was a difference in BS according to the timing of simethicone administration (P < .001). The group taking simethicone on the day of the test had a better BS than the group taking simethicone the day before (P < .001). The group taking simethicone on the previous day had a better BS than the control group (P = .001). In the group of taking simethicone on the examination day, the number of irrigations was lower, and satisfaction with the inspector was higher than group of taking simethicone on previous day and control group (both P < .001). The insertion time showed a non-significantly decreasing trend (P = .417). CONCLUSION: Administering simethicone reduced bubbles and facilitated effective colonoscopy, especially when administrating it on the day of examination. It needs to be administered on the day of the examination regardless of bowel preparation.

Background/Aims: Hypercontractile esophagus (HE) is a heterogeneous disorder with variable clinical presentations and a natural course, leading to management challenges. This study aims to investigate the characteristics of HE and evaluate its treatment outcomes. Methods: Four Korean referral centers recruited subjects with at least 1 hypercontractile swallow (distal contraction integral > 8000 mmHg·s·cm) in this retrospective observational study. Subjects were classified according to the Chicago classification version 2.0 (CC v2.0), CC v3.0, and CC v4.0. criteria. The clinical and manometric features were also investigated. The treatment modalities and outcomes of subjects with CC v4.0 were evaluated. Results: In total, 59 subjects with at least 1 hypercontractile swallow were analyzed. Among them, 30 (50.8%) had increased integrated relaxation pressure values without meeting the criteria for achalasia. Among the remaining 29 patients, 6 (20.7%) had only 1 hypercontractile swallowing symptom (CC v2.0) and 23 (79.3%) met both the CC v3.0 and v4.0 criteria for HE. Dysphagia (91.3%) was the most prevalent symptom, followed by chest pain (56.5%), regurgitation (52.2%), globus (34.8%), heartburn (21.7%), and belching (8.7%). Twenty (87.0%) patients received medical treatment, and 8 (47.1%) and 5 (29.4%) showed moderate and significant improvements, respectively. Proton pump inhibitors were the most common option (n = 15, 65.2%), followed by calcium channel blockers (n = 6, 26.1%). One patient received peroral endoscopic myotomy and showed significant symptom improvement. Conclusions: Sixty-one percent of patients who meet the diagnostic criteria for the high-resolution manometry are diagnosed with symptomatic HE based CC v4.0. Chest pain and regurgitation were also observed in over half of them. The overall medical treatment efficacy was moderate.
RESUMEN
BACKGROUND: Tegoprazan is a novel potassium-competitive acid blocker used to treat acid-related disorders. AIM: To compare tegoprazan 25 mg with lansoprazole 15 mg as maintenance therapy in healed erosive oesophagitis (EE) METHODS: In this phase 3, double-blind, multi-centre study, patients with endoscopically confirmed healed EE were randomised 1:1 to receive tegoprazan 25 mg or lansoprazole 15 mg once daily for up to 24 weeks. The primary efficacy endpoint was the endoscopic remission rate after 24 weeks. The secondary efficacy endpoint was the endoscopic remission rate after 12 weeks. Safety endpoints included adverse events, clinical laboratory results and serum gastrin and pepsinogen I/II levels. RESULTS: We randomised patients to tegoprazan 25 mg (n = 174) or lansoprazole 15 mg (n = 177). Most had mild EE (Los Angeles (LA) grade A: 57.3%, LA grade B: 37.3%). The endoscopic remission rate after 24 weeks was 90.6% with tegoprazan and 89.5% with lansoprazole. Tegoprazan was not inferior to lansoprazole for maintaining endoscopic remission at 24 weeks and 12 weeks. In subgroup analysis, tegoprazan 25 mg showed no significant difference in maintenance rate according to LA grade (p = 0.47). The maintenance effect of tegoprazan was consistent in CYP2C19 extensive metabolisers (p = 0.76). Increases in serum gastrin were not higher in tegoprazan-treated than lansoprazole-treated patients. CONCLUSIONS: Tegoprazan 25 mg was non-inferior to lansoprazole 15 mg in maintenance of healing of mild EE. In this study, tegoprazan had a similar safety profile to lansoprazole.

BACKGROUND: Fexuprazan, a novel potassium-competitive acid blocker, reversibly suppresses the K+/H+-ATPase enzyme in proton pumps within gastric parietal cells. Fexuprazan's suppression of gastric acid was maintained in healthy individuals for 24 h in a dose-dependent manner. AIM: To compare fexuprazan to esomeprazole and establish its efficacy and safety in patients with erosive esophagitis (EE). METHODS: Korean adult patients with endoscopically confirmed EE were randomized 1:1 to receive fexuprazan 40 mg or esomeprazole 40 mg once daily for eight weeks. The primary endpoint was the proportion of patients with healed EE confirmed by endoscopy at week 8. The secondary endpoints included the healing rate of EE at week 4, symptom response, and quality of life assessment. Safety profiles and serum gastrin levels were compared between the groups. RESULTS: Of the 263 randomized, 218 completed the study per protocol (fexuprazan 40 mg, n = 107; esomeprazole 40 mg, n = 111). Fexuprazan was non-inferior to esomeprazole regarding the healing rate at week 8 [99.1% (106/107) vs 99.1% (110/111)]. There were no between-group differences in the EE healing rate at week 4 [90.3% (93/103) vs 88.5% (92/104)], symptom responses, and quality of life assessments. Additionally, serum gastrin levels at weeks 4 and 8 and drug-related side effects did not significantly differ between the groups. CONCLUSION: Fexuprazan 40 mg is non-inferior to esomeprazole 40 mg in EE healing at week 8. We suggest that fexuprazan is an alternative promising treatment option to PPIs for patients with EE.

BACKGROUND: Increasing clarithromycin resistance has led to changes in several guidelines for treatment of Helicobacter pylori infections. We compared the H. pylori eradication rates of the empirical concomitant therapy (CoT) and a tailored therapy (TaT) using dual-priming oligonucleotide-based polymerase chain reaction to detect mutations in the 23S rRNA gene that are related to clarithromycin resistance. METHODS: Between June 2020 and May 2021, 290 patients were enrolled and randomly assigned to 2 groups. In the CoT group, the patients received rabeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg twice daily for 14 days. In the TaT group, point mutation-negative patients received rabeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg twice daily for 14 days and point mutation-positive patients received rabeprazole 20 mg twice daily, metronidazole 500 mg thrice daily, and bismuth 120 mg and tetracycline 500 mg 4 times daily for 14 days. RESULTS: A total of 290 and 261 patients were included in the intention-to-treat (ITT) and per-protocol (PP) analyses, respectively. A2142G and/or A2143G point mutations were identified in 28.6% of the patients. No significant difference in eradication rates were observed between the 2 groups as per ITT (CoT, 82.8% and TaT, 85.5%, P = .520) and PP (CoT, 88.6% and TaT, 94.6%, P = .084) analyses. In point mutation-positive patients, the eradication rates in the CoT group were lower than those in the TaT group as per ITT (69.8% and 87.5%, respectively, P = .050) and PP (76.9% and 97.1%, respectively, P = .011) analyses. CONCLUSION: CoT and TaT showed similar overall eradication rates for H. pylori. However, CoT eradication rate was suboptimal, especially in point mutation-positive patients.

Among the plethora of foreign body impactions, fish bones are common examples that patients may struggle to properly disclose in clinical situations. This study investigated whether patients could pinpoint where the ingested fish bone was lodged. In addition, we investigated the differences between fish bone and other foreign bodies, the usefulness of computed tomography (CT), and the related risk factors for hospitalization. The cases of patients who underwent an endoscopic removal of fish bone between April 2008 and April 2020 were retrospectively reviewed. The clinical outcomes, X-ray scan, CT, and complications of each patient were investigated. A total of 96 patients were included in this study. The mean size of the impacted fish bone was 23.78 mm, and most were found in the upper esophagus (n = 38). There was a weak correlation between pain location and the actual lesion location (r = 0.419, P < .001). Compared to those of other foreign bodies, the location of impacted fish bones was different (P < .001), the X-ray detection rate of fish bones was lower (P < .001), and the complication incidence was higher (P = .030). CT (95.89%) showed higher sensitivity than X-ray scanning (11.24%) (P < .001). Foreign body size (P = .004) and door-to-endoscopy time (P = .029) were related to admission. Patients only managed to point out the approximate location of the ingested fish bone. CT detected fish bones well, but scans should include at least the entire esophagus instead of solely the area where pain is felt. Fish bone impaction has different clinical characteristics from other foreign bodies. Endoscopic removal without delay can reduce the admission rates.

BACKGROUND: A history of abdominal surgery is associated with difficulty in colonoscopy insertion. Few studies have reported effective colonoscopy insertion for patients who underwent abdominal surgery due to stomach cancer. AIM: We aimed to compare the impact of supine position (SP) and left lateral position (LLP) as the starting position of colonoscopy insertion in patients who underwent abdominal surgery due to stomach cancer. METHODS: This was a prospective, randomized controlled trial. Patients undergoing colonoscopy for screening or post-polypectomy surveillance after gastrectomy due to stomach cancer were enrolled and randomized to the SP or LLP group as the starting position of colonoscopy insertion. All colonoscopic examinations were performed with a transparent cap. The primary outcome was to compare the cecal intubation time between the two groups. RESULTS: A total of 224 patients were enrolled. The mean cecal intubation time was not significantly different between the SP and LLP groups (364.5 s versus 306.9 s; p = 0.105). In patients with a lower body mass index (< 21 kg/m2) or who underwent gastrectomy within three years, the mean cecal intubation time of the LLP group was shorter than the SP group. In the multivariate analysis for the factors affecting to increase in the cecal intubation time (> 5 min), the starting position was not an independent factor. CONCLUSION: Either the SP or LLP could serve as a possible starting position of colonoscopy insertion for patients who underwent abdominal surgery due to stomach cancer.

BACKGROUND/AIMS: Helicobacter pylori infection is presumably associated with iron deficiency and iron deficiency anemia (IDA). This study aimed to evaluate the relationship between H. pylori infection and the decline in iron stores in non-elderly adults during their health check-ups. METHODS: We identified a total of 1,069 subjects who were tested for iron, ferritin, and total iron-binding capacity during their health check-ups, from January 2016 to May 2017. Of these, subjects who underwent endoscopy via rapid urease test and those aged 65 years or below were finally enrolled. RESULTS: Overall, 281 subjects were enrolled, and 187 patients (66.5%) tested positive for H. pylori. The mean age was 36.1 years (range, 22 to 65), and 176 subjects (62.6%) were male. The mean levels of hemoglobin (14.1 ± 1.7 g/dL vs. 14.6 ± 1.4 g/dL, p = 0.019) and ferritin (121.7 ± 106.9 ng/mL vs. 151.8 ± 107.8 ng/mL, p = 0.027) in the H. pylori-positive group were significantly lower than those in the H. pylori-negative group. Iron deficiency (ferritin < 30 ng/mL) was more common in patients with H. pylori infection (p = 0.002). There was no significant difference in anemia (hemoglobin < 13 g/dL in men, < 12 g/dL in women) or IDA (anemia, ferritin < 10 ng/mL, and transferrin saturation < 16%) with H. pylori. Logistic regression analysis demonstrated that female sex (odds ratio, 197.559; 95% confidence interval, 26.461 to 1,475.015) and H. pylori infection (odds ratio, 3.033; 95% confidence interval, 1.216 to 7.567) were factors associated with iron deficiency. CONCLUSION: H. pylori infection is associated with iron deficiency, suggesting a decline in iron stores among infected non-elderly adults.

BACKGROUND: Undifferentiated-type early gastric cancer (UD EGC) shows lower curative resection rates after endoscopic submucosal dissection (ESD). Additional surgery is recommended after non-curative resection. We evaluated the long-term outcomes of ESD followed by additional surgery after non-curative resection in UD EGC compared to those for surgery as initial treatment. METHODS: We reviewed 1139 UD EGC patients who underwent ESD at 18 hospitals and 1956 patients who underwent surgery at two hospitals between February 2005 and May 2015. We enrolled 636 patients with non-curative ESD and 1429 surgery subjects beyond the curative ESD criteria. Among them, 133 patients with additional surgery after ESD (ESD + OP group) and 252 patients without additional surgery (ESD-only group) were matched 1:1 using propensity scores to patients with surgery as initial treatment (surgery group). Overall survival (OS) and recurrence-free survival (RFS) were compared. RESULTS: Signet ring cell carcinoma and poorly differentiated adenocarcinoma (PDA) were observed in 939 and 1126 cases, respectively. OS was significantly longer in the surgery group than in the ESD + OP group, especially for PDA. However, RFS was shorter in the ESD-only group than those in the ESD + OP and surgery groups. RFS did not differ significantly between the ESD + OP and surgery groups. Compared to the surgery group, the ESD-only and ESD + OP groups had an overall hazard ratio for RFS of 3.58 (95% confidence interval 1.44-8.88) and 0.46 (0.10-2.20), respectively. CONCLUSIONS: ESD followed by additional surgery after non-curative resection showed comparable cancer-specific outcomes to initial surgery in UD EGC.

BACKGROUND: Endoscopic submucosal dissection (ESD) is an effective treatment for early gastric cancer (EGC); however, its curative resection rate is low for undifferentiated-type EGC. We developed and externally validated a prediction model for curative ESD of undifferentiated-type EGC. METHODS: In this cross-sectional study, we included 448 patients who underwent ESD for undifferentiated-type EGC at 18 hospitals in Korea between 2005 and 2015 in the development cohort and 1342 patients who underwent surgery at two hospitals in the validation cohort. A prediction model was developed using the logistic regression model. RESULTS: Endoscopic tumor size 1-2 cm (odds ratio [OR], 2.40; 95% confidence interval [CI] 1.54-3.73), tumor size > 2 cm (OR, 14.00; 95% CI 6.81-28.77), and proximal tumor location from the lower to upper third of the stomach (OR, 1.45; 95% CI 1.03-2.04) were independent predictors of non-curative ESD. A six-score prediction model was developed by assigning points to endoscopic tumor size > 2 cm (five points), tumor size 1-2 cm (two points), upper third location (two points), and middle third location (one point). The rate of curative ESD ranged from 70.6% (score 0) to 11.6% (score 5) with an area under the receiver operating characteristic curve (AUC) of 0.720 (95% CI 0.673-0.766). The model also showed good performance in the validation cohort (AUC, 0.775; 95% CI 0.748-0.803). CONCLUSIONS: This six-score prediction model may help in predicting curative ESD and making informed decisions about the treatment selection between ESD and surgery for undifferentiated-type EGC.
