ABSTRACT

Background@#No definite guidelines for the management of small esophageal subepithelial tumors (SETs) have been established, because there are limited data and studies on their natural history. We aimed to assess the natural history and propose optimal management strategies for small esophageal SETs. @*Methods@#Patients diagnosed as esophageal SETs ≤ 30 mm in size between 2003 and 2017 using endoscopic ultrasound (EUS) with a minimal follow-up of 3 months were enrolled, and their esophagogastroduodenoscopy (EGD) and EUS were retrospectively reviewed. @*Results@#Of 275 esophageal SETs in 262 patients, the initial size was < 10 mm, 10–20 mm, and 20–30 mm in 104 (37.8%), 105 (38.2%), and 66 (24.0%) lesions, respectively. Only 22 (8.0%) SETs showed significant changes in size and/or echogenicity and/or morphology at a median of 40 months (range, 4–120 months). Tissues of 6 SETs showing interval changes were obtained using EUS-guided fine needle aspiration biopsy; 1 was identified as a gastrointestinal stromal tumor (GIST) and was surgically resected, while the other 5 were leiomyomas and were regularly observed. Eight SETs showing interval changes were resected surgically or endoscopically without pathological confirmation; 1 was a GIST, 2 were granular cell tumors, and the other 5 were leiomyomas. @*Conclusion@#Regular follow-up with EGD or EUS may be necessary for esophageal SETs ≤ 30 mm in size considering that small portion of them has a possibility of malignant potential. When esophageal SETs ≤ 30 mm show significant interval changes, pathological confirmation may precede treatment to avoid unnecessary resection.

ABSTRACT

Background/Aims@#The treatment of superficial esophageal neoplasms (SENs) in cirrhotic patients is challenging and rarely investigated. We evaluated the outcomes of endoscopic submucosal dissection (ESD) to determine the efficacy and safety of treating SENs in patients with liver cirrhosis. @*Methods@#The baseline characteristics and treatment outcomes of patients who underwent ESD for SENs between November 2005 and December 2017 were retrospectively reviewed. @*Results@#ESD was performed in 437 patients with 481 SENs, including 15 cirrhotic patients with 17 SENs. En bloc resection (88.2% vs. 97.0%) and curative resection (64.7% vs. 78.9%) rates were not different between the cirrhosis and non-cirrhosis groups (p=0.105 and p=0.224, respectively). Bleeding was more common in cirrhotic patients (p=0.054), and all cases were successfully controlled endoscopically. The median procedure and hospitalization duration did not differ between the groups. Overall survival was lower in cirrhotic patients (p=0.003), while disease-specific survival did not differ between the groups (p=0.85). @*Conclusions@#ESD could be a safe and effective treatment option for SENs in patients with cirrhosis. Detailed preprocedural assessments are needed, including determination of liver function, esophageal varix status, and remaining life expectancy, to identify patients who will obtain the greatest benefit.

ABSTRACT

Background/Aims@#Postprocedural bleeding is known to be relatively low after argon plasma coagulation (APC) for gastric neoplasms; however, there are few studies proving the effect of antithrombotic agents. This study aimed to analyze the incidence of delayed bleeding (DB) based on antithrombotic agents administered and to identify the risk factors for DB in APC for gastric tumors. @*Methods@#A total of 785 patients with 824 lesions underwent APC for single gastric neoplasm between January 2011 and January 2018. After exclusion, 719 and 102 lesions were classified as belonging to the non-antithrombotics (non-AT) and AT groups, respectively. The clinical outcomes were compared between the two groups, and we determined the risk factors for DB in gastric APC. @*Results@#Of the total 821 cases, DB occurred in 20 cases (2.4%): 17 cases in the non-AT group and three cases in the AT group (2.4% vs 2.9%, p=0.728). Multivariate analysis of the risk factors for DB confirmed the following significant, independent risk factors: male sex (odds ratio, 7.66; 95% confidence interval, 1.02 to 57.69; p=0.048) and chronic kidney disease (odds ratio, 4.51; 95% confidence interval, 1.57 to 13.02; p=0.005). Thromboembolic events and perforation were not observed in all patients regardless of whether they took AT agents. @*Conclusions@#AT therapy is acceptably safe in gastric APC because it does not significantly increase the incidence of DB. However, patients with chronic kidney disease or male sex need to receive careful follow-up on the incidence of post-APC bleeding.

ABSTRACT

Purpose@#The association of serum lipids with gastric cancer is controversial. We clarified the role of serum lipids in the development, progression, and prognosis of gastric cancer. @*Materials and Methods@#In total, 412 patients diagnosed with gastric cancer were prospectively recruited, and 2,934 control subjects who underwent screening endoscopy were enrolled from December 2013 to March 2017 to conduct a case-control study in a tertiary center. Serum lipid profiles, including total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), apolipoprotein A-I (apoA-I), and apolipoprotein B, and clinicopathologic characteristics were analyzed. @*Results@#The gastric cancer group showed significantly lower HDL-C, higher LDL-C, and lower apoA-I level than the control group. In multivariate analysis, old age (odds ratio [OR], 1.051; p < 0.001), smoking (OR, 1.337; p < 0.001), a family history of gastric cancer (OR, 2.038; p < 0.001), Helicobacter pylori seropositivity (OR, 4.240; p < 0.001), lower HDL-C (OR, 0.712; p=0.020), and higher LDL-C (p=0.002) were significant risk factors for gastric cancer. Lower HDL-C and higher LDL-C remained significant after adjustments for covariates, including age and sex. In a subgroup analysis of the gastric cancer group, lower TG levels were associated with undifferentiated histology. No serum lipids were associated with overall survival. @*Conclusion@#Lower HDL-C and higher LDL-C were associated with the risk of gastric cancer, even after adjusting for age, sex, and other factors. In the gastric cancer group, undifferentiated histology was associated with lower TG levels.

ABSTRACT

Background/Aims@#The learning curve is essential in endoscopic submucosal dissection (ESD) training to improve outcomes and reduce the risk of procedure-related complications. We compared the outcomes of gastric ESD in live pigs performed by inexperienced endoscopists with or without ex vivo training. @*Materials and Methods@#At the Olympus Medical Training and Education Center, nine endoscopists inexperienced in ESD were randomly divided into two groups (group A: ex vivo training followed by in vivo training; group B: in vivo training only), and they performed gastric ESDs. @*Results@#A total of 18 ESDs were performed. The en bloc resection rate was 88.9% (16/18), and the complete resection rate was 94.4% (17/18). The median specimen size was 2.5 cm in group A and 2.1 cm in group B (P=0.227). There was no significant difference in the procedure time between the two groups, except for the marking time (0′58″ vs. 2′58″, P=0.027). However, group A took a shorter time in dissecting the same area than group B (109 vs. 246 sec/cm2, P=0.083). Complication rates were not significantly different between both groups. @*Conclusions@#The procedure time during in vivo ESD training in pigs may be shortened by prior ex vivo training. However, the ex vivo model presented poor air inflation, unstable fixation, and excessive mucosal hardness for cutting. An advanced simulator or sufficient ex vivo training may be effective in training for the ESD procedure.

ABSTRACT

Background@#Endoscopic surveillance after total gastrectomy (TG) for gastric cancer is routinely performed to detect tumor recurrence and postoperative adverse events.However, the reports on the clinical benefits of endoscopic surveillance are ambiguous. We investigated the clinical benefit of endoscopic surveillance after TG for gastric cancer. @*Methods@#We analyzed 848 patients who underwent TG with R0 resection for gastric cancer between 2011 and 2012 (380 early gastric cancer and 468 advanced gastric cancer) and underwent regular postoperative surveillance with endoscopy and abdominopelvic computed tomography (CT) with contrast. @*Results@#Median follow-up periods were 58 months for both endoscopy (range, 3–96) and abdominopelvic CT (range, 1–96). Tumor recurrence occurred in 167 patients (19.7%), of whom seven (4.2%) were locoregional recurrences in the peri-anastomotic area (n = 5) or regional gastric lymph nodes (n = 2). Whereas the peri-anastomotic recurrences were detected by both endoscopy and abdominopelvic CT, regional lymph node recurrences were only detected by abdominopelvic CT. Out of the 23 events of postoperative adverse events, the majority (87%) were detected by radiologic examinations; three events of benign strictures in the anastomotic site were detected only by endoscopy. @*Conclusion@#Endoscopic surveillance did not have a significant role in detecting locoregional tumor recurrence and postoperative adverse events after TG with R0 resection for gastric cancer. Routine endoscopic surveillance after TG may be considered optional and performed according to the capacities of each clinical setting.

ABSTRACT

Background/Aims@#Data regarding the prognosis of early esophageal cancer are lacking. This study investigated the long-term outcomes and factors affecting the survival of patients with mucosal esophageal squamous cell carcinoma (T1aESCC). @*Methods@#We analyzed the clinical and tumor-specific parameters of 263 patients who received surgical resection (SR; n=63) or endoscopic resection (ER; n=200) for T1aESCC. Underlying comorbidities were scored using the Charlson comorbidity index (CCI). Overall survival (OS) was the primary outcome, and multivariate regression analysis was performed to predict factors for OS. @*Results@#Of the study patients (age, 64.5±8.0 years), the CCI was 1.0±1.4 in the ER group and 0.6±0.9 in the SR group (p=0.107). The 5-year OS rate during follow-up (54.4±20.4 months) was 85.7% (ER group, 86.8%; SR group, 82.4%; p=0.631). The cumulative 5-year incidence of esophageal cancer recurrence was 10.5% in the ER group (vs 0% in the SR group). The overall mortality rate was 12.9% (ER group, 12.0%; SR group, 15.9%; p=0.399). The most common cause of mortality was second primary cancers in the ER group (75%) and organ dysfunction or postoperative complications in the SR group (70%). According to multivariate analysis, only CCI was significantly associated with OS (p2 and in those with a CCI ≤2 was 60.2% and 88.2%, respectively (p<0.001). The treatment method (ER vs SR) was not a significant affecting factor (p=0.238). @*Conclusions@#The long-term prognosis of patients with T1aESCC was significantly associated with underlying comorbidities.

ABSTRACT

Background/Aims@#Percutaneous endoscopic gastrostomy (PEG) is usually performed on patients with chronic underlying diseases in the general ward (GW). This study evaluated the clinical outcomes of PEG performed on patients in the surgical intensive care unit (SICU) compared with those of PEG performed in the GW. @*Methods@#The medical records of 27 patients in the SICU and 263 in the GW, who underwent PEG between January 2013 and July 2017, were retrospectively reviewed. @*Results@#The median age of the 27 SICU patients was 66 years, and their median body mass index was 21.1 kg/m2. In the SICU group, the median baseline Sequential Organ Failure Assessment (SOFA) score was 4, and the median Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 16. The median interval between surgery and PEG in SICU patients was 30 days, with a PEG failure rate of 3.7%. Acute complications in SICU patients included bleeding (7.4%) and ileus (11.1%), while chronic complications included aspiration pneumonia (7.4%) and tube obstruction (3.7%). The rates of acute and chronic complications did not differ significantly between the SICU and GW groups. The 30-day mortality rate was 14.8% in SICU patients and 5.3% in GW patients (p=0.073). @*Conclusions@#PEG is a safe and feasible method of enteral feeding for critically ill patients who require ICU care after surgery.

ABSTRACT

Background@#Accurate prediction of tumor invasion depth in superficial esophageal squamous carcinoma (SESC) is essential for deciding the appropriate treatment strategy.We proposed novel endoscopic criteria to differentiate between mucosal and submucosal esophageal cancers and to evaluate the diagnostic accuracy and usefulness of the criteria. @*Methods@#A total of 352 patients who underwent endoscopic or surgical resection for SESC between 1991 and 2010 were included. First, the novel endoscopic criteria were created based on the endoscopic features of 60 randomly selected patients as follows: for T1m cancers, I.flat or slightly elevated or depressed lesion with smooth/even surface of any size, II. slightly elevated lesion of ≤ 1 cm with granular or uneven surface, III. hyperemic flat lesion of ≤ 3 cm with granular or uneven surface, IV. slightly depressed lesion of ≤ 2 cm with uneven surface and for T1sm cancers, I. irregularly (unevenly) nodular or protruded lesion of any size, II. slightly elevated lesion of > 1 cm with granular or uneven surface, III. hyperemic flat lesion of > 3 cm with granular or uneven surface, IV. irregularly (unevenly) depressed lesion of > 2 cm, and V. ulcerative lesion of any size. Next, the endoscopic findings of the remaining 292 patients were reviewed according to the criteria. @*Results@#The accuracy of novel endoscopic criteria was 79.5% (232/292). The sensitivity and specificity of mucosal cancers were 78.4% and 81.0%, respectively, whereas those for submucosal cancers were 81.0% and 78.4%, respectively. The accuracy for mucosal cancers was high (97.3%, 72/74) when the lesions were flat or slightly elevated/depressed with smooth/even surface regardless of size, whereas that for submucosal cancers was high (85.7%, 18/21) when the lesions were irregularodular protrusions regardless of size. In multivariate analysis, macroscopic type IIb lesion was identified as an independent factor affecting accuracy (P < 0.05). The difference in recurrence-free survival rates between endoscopically mucosal and submucosal cancers was significant (P = 0.026). @*Conclusion@#The novel endoscopic criteria appear to be accurate and useful in predicting invasion depth in SESC. Our criteria might help not only to decide the treatment strategy between surgery and endoscopic resection but also to predict the outcomes of SESC.

ABSTRACT

BACKGROUND/AIMS: The epidemiology and pathogenesis of eosinophilic esophagitis (EoE) remain unclear in Asian countries. We investigated clinicopathological characteristics and diagnostic trends of EoE, and evaluated 3 tissue biomarkers for correlation with disease activity and treatment response in Korean patients with EoE. METHODS: We retrospectively reviewed 25 271 esophageal biopsies performed during upper endoscopies between 2006 and 2017. We diagnosed EoE based on ≥ 15 eosinophils/high-power field (HPF) and, symptoms of esophageal dysfunction. We performed immunohistochemical analysis for tryptase, eosinophilic derived neurotoxin (EDN), and eotaxin-3. RESULTS: We diagnosed EoE in 72 patients (53 men and 19 women; mean age, 46.2 years) with presenting symptoms of, dysphagia (15.3%), epigastric pain (31.9%), and heartburn (30.6%). The diagnostic rate of EoE considerably increased between 2006 and 2017, from 0.29 diagnoses to 7.99 diagnoses per 1000 esophageal biopsies (P < 0.001). The mean peak eosinophil count (PEC) was 56.0 (± 77.8)/HPF. Whereas the EDN (rho = 0.667, P < 0.001) and eotaxin-3 levels (rho = 0.465, P < 0.001) correlated with PEC, tryptase and PEC were weakly correlated (rho = 0.291, P = 0.013). EDN (rho = 0.279, P = 0.017), and tryptase (rho = 0.279, P = 0.033) correlated with the inflammatory score of Eosinophilic Esophagitis Endoscopic Reference Score. Immunohistochemical analysis and changes in tryptase, EDN, and eotaxin-3 levels were associated with histologic and endoscopic improvements. CONCLUSIONS: EoE incidence considerably increased during the 12-year period, regardless of endoscopic esophageal biopsy rate. Tryptase, EDN, and eotaxin-3 levels in esophageal biopsy specimens could be promising biomarkers for disease activity, symptom, and endoscopic response in Korea.

ABSTRACT

BACKGROUND/AIMS: The prevalence of eosinophilic esophagitis (EoE) is reportedly increasing in Western countries. However, its prevalence in Korea remains unknown. We investigated the diagnostic trends and clinical characteristics of EoE in Korea. METHODS: Using an endoscopic database maintained at a tertiary care center, we retrospectively reviewed the biopsy reports regarding 18 399 biopsy specimens collected from all patients who underwent esophagogastroduodenoscopy and esophageal biopsy at this facility between 2006 and 2014. The presence of more than 15 eosinophils per high-power field with symptoms related to esophageal dysfunction was considered to indicate EoE. RESULTS: A total of 37 patients (male:female ratio, 29:8; mean age, 44.0 ± 13.0 years) were diagnosed with EoE. These patients presented with dysphagia (21.6%), epigastric pain (21.6%), heartburn (24.3%), and other symptoms (32.4%). Typical endoscopic appearance of EoE was noted in 33 cases (89.1%) and included linear furrows in 24 cases (64.8%), ringed esophagus in 10 cases (27.0%), and white exudates in 11 cases (29.7%). The median eosinophilic count was 25 per high-power field (interquartile range, 20–70). Notable histopathological findings included eosinophilic microabscesses in 21 cases (56.7%). The diagnosis rate of EoE was found to have increased from 2006 and to 2014 (P-value < 0.001 by the Cochran-Armitage trend test). CONCLUSIONS: The number of patients with EoE appears to have increased significantly over the 9-year period investigated, while the number of endoscopic investigations increased only marginally. Greater awareness of EoE and the role of esophageal biopsies should be considered.

ABSTRACT

BACKGROUND/AIMS: We aimed to compare the outcomes of Helicobacter pylori eradication in patients receiving sequential therapy (ST) depending on the use of ecabet sodium (ES). MATERIALS AND METHODS: Between January to December 2015, 176 patients randomly received either ST alone (n=72) or 10-day ES therapy combined with ST (n=104). After applying the exclusion criteria, 56 patients were finally assigned to the ST-only group and 84 to the ST with ES group. We retrospectively reviewed and analyzed the H. pylori eradication rate and adverse events between the two groups. RESULTS: Among the 140 patients, 121 (86.4%) achieved successful H. pylori eradication and 24 (17.1%) had adverse events. Eradication was achieved in 50 patients (89.3%) in the ST-only group and in 71 patients (84.5%) in the ST with ES group (P=0.420). No significant difference in the incidence of adverse events was found between the ST-only and ST with ES groups (12.5% vs. 20.2%, respectively; P=0.234). However, the ST with ES group tended to have a higher prevalence of nausea or vomiting than the ST-only group (11.9% vs. 1.8%; P=0.050). CONCLUSIONS: ST showed a good H. pylori eradication rate without deteriorating the adverse events regardless of adding ES.

ABSTRACT

BACKGROUND/AIMS: We aimed to compare the outcomes and timing of Helicobacter pylori eradication in patients with iatrogenic and peptic ulcers. MATERIALS AND METHODS: This was a retrospective study of 183 patients treated between 2012 and 2015 with 7-day standard triple therapy after endoscopic resection (ER). The patients were enrolled as the iatrogenic ulcer group and assigned to an early treatment group (n=139, H. pylori eradication initiated 2 days after ER) and a late treatment group (n=44, 8 weeks after ER). During the same period, 152 patients with peptic ulcer were assigned to the peptic ulcer group. RESULTS: Successful H. pylori eradication was achieved in 141 patients (77.0%) in the iatrogenic ulcer group and 114 (75.0%) in the peptic ulcer group (P=0.661). Among the ER patients, the eradication rate was 79.9% (n=111) in the early treatment group and 68.2% (n=30) in the late treatment group (P=0.109). The adverse event rate was significantly higher in the peptic ulcer group than in the iatrogenic ulcer group (13.8% vs. 4.9%, P=0.005). Compliance and adverse events did not significantly differ between the early and late treatment groups. CONCLUSIONS: In iatrogenic ulcer, H. pylori eradication can be performed with a relatively lower adverse event rate, regardless of treatment timing, than that in peptic ulcer.
