RESUMO
BACKGROUND: Patients achieving pathological complete response (pCR) post-neoadjuvant chemoradiotherapy (nCRT) and surgery for locally advanced esophageal squamous cell carcinoma (ESCC) have a favorable prognosis. However, recurrence occurs in approximately 20-30% of all patients, with few studies evaluating their prognostic factors. We identified these prognostic factors, including inflammation-based markers, in patients with ESCC showing pCR after nCRT and surgery. PATIENTS AND METHODS: Patients with ESCC undergoing esophagectomy post-nCRT (January 2007-August 2017) were studied. Survival analysis evaluated 5-year overall (OS) and recurrence-free survival (RFS). Risk factors, including inflammation factors, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (PLR), were analyzed using Cox-proportional hazards model. RESULTS: Overall, 123patients participated herein. After a median follow-up duration of 67 months (44-86 months), 17 patients (12.3%) had recurrent disease. The 5-year OS and RFS rates were 71.6% and 68.0%, respectively. In the multivariable analysis, older age ( ≥ 60 years) [hazard ratio (HR) 3.228, 95% confidence interval (CI) 1.478-7.048, p = 0.003], higher pretreatment T stage (≥ T3; HR 2.563, 95% CI 1.335-4.922, p = 0.005), nonapplication of induction chemotherapy (HR 2.389, 95% CI 1.184-4.824, p = 0.015), and higher post-nCRT PLR (≥ 184.2; HR 2.896, 95% CI 1.547-5.420, p = 0.001) were poor independent prognostic factors for 5-year RFS. The patient group with three to four identified factors with poor outcomes exhibited a 5-year RFS rate of 46.2%. CONCLUSIONS: Significant prognostic factors include higher post-nCRT PLR, older age, higher clinical T stage, and nonapplication of induction chemotherapy. Identifying higher recurrence risk patients is crucial for tailored follow-up and treatment.
RESUMO
BACKGROUND AND AIMS: Argon plasma coagulation (APC) could be considered a treatment modality for small gastric low-grade dysplasia (LGD) instead of endoscopic resection. Our study investigated the clinical outcomes of APC for treating gastric LGD and associated variables with local recurrence. METHODS: This study included 911 patients who underwent APC for gastric neoplasms at the tertiary hospital from July 2007 to March 2022 with a minimal follow-up of 12 months. Of these patients, 112 without any information about Helicobacter pylori infection status, 164 who underwent APC for salvage therapy, 5 with high-grade dysplasia, and 12 with cancer were excluded. Through a retrospective review of medical data, the clinical outcomes and variables associated with the local recurrence were analyzed. RESULTS: A total of 618 patients with LGD (median age, 64 years) were followed up for a median of 30 months, and local recurrence has happened in 21 (3.4%) patients. Multivariate analysis showed that lesion size (hazard ratio, 1.06; 95% confidential interval, 1.01-1.12) was associated with the local recurrence. Among 557 lesions smaller than 10 mm, local recurrence was found in 14 (2.6%) cases, and local recurrence was found in 7 (9.5%) cases of 109 tumors larger than 10 mm (P < .004). CONCLUSIONS: In gastric LGD smaller than 10 mm without scars, APC is a good treatment modality in place of endoscopic resection. However, when a lesion is larger, APC should be selected carefully with close monitoring.

BACKGROUND: Most gastric leiomyomas are asymptomatic and benign subepithelial tumors (SETs); however, some may increase in size or become symptomatic. Understanding their natural history is therefore important to their management. We investigated the natural history of histologically proven gastric leiomyomas. METHODS: We retrospectively reviewed histologically proven gastric leiomyoma cases at a tertiary center. The baseline characteristics of these cases were analyzed, and those with a follow-up period of at least 12 months without immediate resection were evaluated. The primary outcome was the frequency of size increase of more than 25% during the follow-up period, and the secondary outcome was the histopathologic results in cases that underwent resection. RESULTS: Among the 231 patients with histologically proven gastric leiomyomas, the most frequent location was the cardia (77.1%), and the median size was 3 cm (IQR 2-4 cm). Eighty-four cases were followed up over a median period of 50.8 months (IQR 27.2-91.3 months). During the follow-up period, tumor size increased in two cases (2.4%). Surgical results showed that one case was leiomyoma, and the other was leiomyosarcoma. Among the remaining cases without change in size, 15 underwent surgical resection (n = 10) or endoscopic resection (n = 5), and all cases were confirmed as leiomyoma. CONCLUSIONS: Most gastric leiomyomas are benign SETs, and an increase in size is not frequent, even in large-sized cases. Close monitoring with routine follow-up without resection may be sufficient in cases of histologically proven gastric leiomyoma. However, in cases of ulceration or size increase, resection may be beneficial.

BACKGROUND: Postendoscopic submucosal dissection electrocoagulation syndrome (PEECS) is commonly observed after performing endoscopic submucosal dissection (ESD) for esophageal neoplasia. However, data on the incidence and risk factors for PEECS in the esophagus are lacking due to an unclear definition of PEECS and varied clinical settings. Therefore, we aimed to determine the risk factors for PEECS in patients undergoing ESD for esophageal neoplasia. METHODS: We retrospectively reviewed data of relevant clinical and endoscopy-specific parameters from 202 consecutive patients with esophageal neoplasias (139 carcinomas and 63 dysplasias) who underwent ESD under general anesthesia. Esophageal PEECS was defined by satisfying at least two of the following criteria: fever ≥ 37.8 °C, leukocytosis ≥ 10,800/mm3, and localized chest pain ≥ 5/10 points as assessed on a numeric rating scale within 24 h after ESD. Significant factors associated with PEECS were determined by regression analysis. RESULTS: PEECS was recorded in 98 of 202 (48.5%) patients. Patients with PEECS exhibited a larger tumor size (25.0 vs. 17.0 mm, P = 0.002), longer procedure (40.0 vs. 29.5 min, P = 0.021) and hemostasis times (5.0 vs. 3.5 min, P = 0.004), required greater submucosal injection volume (60.0 mL vs. 50.0 mL, P = 0.030), and had a lower rate of local steroid injection (4.1% vs. 12.5%, P = 0.029) than those without PEECS. Multivariate regression analysis revealed tumor size ≥ 17 mm (P = 0.047), procedure time ≥ 33 min (P = 0.027), and hemostasis time ≥ 5 min (P = 0.007) as risk factors for PEECS. In addition, local steroid injection was a significant negatively associated factor (P = 0.001). CONCLUSIONS: Patients with a large tumor, prolonged procedure and hemostasis times are at a high risk of PEECS occurrence. Further, local steroid injection is a negatively associated factor.

INTRODUCTION: This study evaluated the efficacy of fibrin glue for preventing postendoscopic submucosal dissection (ESD) bleeding in high-risk patients for bleeding (expected iatrogenic ulcer size ≥40 mm or receiving antithrombotic therapy). METHODS: A multicenter, open-label, randomized controlled trial was performed at 4 tertiary medical centers in South Korea between July 1, 2020, and June 22, 2022. Patients with gastric neoplasm and a high risk of post-ESD bleeding were enrolled and allocated at 1:1 to a control group (standard ESD) or a fibrin glue group (fibrin glue applied to iatrogenic ulcers after standard ESD). The primary outcome was overall bleeding events within 4 weeks. The secondary outcomes were acute bleeding (within 48 hours post-ESD) and delayed bleeding (48 hours to 4 weeks post-ESD). RESULTS: In total, 254 patients were randomized, and 247 patients were included in the modified intention-to-treat population (125 patients in the fibrin glue group and 122 patients in the control group). Overall bleeding events occurred in 12.0% (15/125) of the fibrin glue group and 13.1% (16/122) of the control group ( P = 0.791). Acute bleeding events were significantly less common in the fibrin glue group than in the control group (1/125 vs 7/122, P = 0.034). Delayed bleeding events occurred in 11.2% (14/125) in the fibrin glue group and 7.3% (9/122) in the control group ( P = 0.301). DISCUSSION: This trial failed to show a preventive effect of fibrin glue on overall post-ESD bleeding in high-risk patients. However, the secondary outcomes suggest a potential sealing effect of fibrin glue during the acute period.

BACKGROUND AND AIM: Although Dieulafoy's lesion (DL) is an important cause of nonvariceal upper gastrointestinal (GI) bleeding, few studies have investigated the clinico-epidemiological outcomes due to its rarity. Here, we investigated clinical features of upper GI bleeding caused by peptic ulcer (PU) or DL and compared endoscopic treatment outcomes. METHODS: Patients with upper GI bleeding resulting from PU or DL who visited emergency room between January 2013 and December 2017 were eligible. Clinical features and treatment outcomes were retrospectively investigated. RESULTS: Overall, 728 patients with upper GI bleeding due to PU (n = 669) and DL (n = 59) were enrolled. The median age was 64 years (interquartile range [IQR], 56-75 years), and 74.3% were male. Endoscopic intervention was performed in 53.7% (n = 359) and 98.3% (n = 58) of the PU and DL groups, respectively (P < 0.0001). Patients were matched by sex, age, body mass index, comorbidity, and past medical history, and 190 PU and 52 DL were finally selected. The rebleeding rates within 7 (7.37% vs 17.31%, P = 0.037) and 30 (7.37% vs 26.92%, P < 0.001) days after initial endoscopy were significantly lower in the PU than in the DL group after propensity score matching. During the median follow-up period of 52 months (IQR, 34-70 months), there was no difference in overall survival rate (67.9% vs 82.7%, P = 0.518). CONCLUSIONS: Although DL is a rare cause of upper GI bleeding, it requires endoscopic hemostasis more frequently and has a higher rate of rebleeding than PU even after therapeutic endoscopy. Endoscopists should pay attention and perform active endoscopic hemostasis for DL bleeding.

BACKGROUND: Left gastric artery (LGA) pseudoaneurysm presenting with upper gastrointestinal (UGI) bleeding is rare but fatal, unless treated. AIMS: We aimed to describe the clinical and endoscopic features of patients with UGI bleeding due to LGA pseudoaneurysms. METHODS: We performed a computerized search of our hospital's de-identified clinical data warehouse to identify patients with UGI bleeding due to an LGA pseudoaneurysm between 2000 and 2020. Patients' electronic medical records and data on esophagogastroduodenoscopy and digital subtraction angiography were reviewed retrospectively. RESULTS: Of 26 patients with an LGA pseudoaneurysm, six patients had UGI bleeding related to an LGA pseudoaneurysm. No patients had previous vascular diseases or pancreatitis. One patient had liver cirrhosis and a history of radiofrequency ablation for hepatocellular carcinoma, one had colon cancer, two had undergone abdominal surgeries, one had received chemoradiotherapy for renal cell carcinoma, and one had no intraabdominal diseases. Symptoms were hematemesis in two, hematochezia in the other two, and melena in the remaining two patients. Esophagogastroduodenoscopy showed a pulsating bulge in the ulcer in two and a large Dieulafoy's lesion-like structure in four patients. All patients achieved hemostasis by angioembolization. CONCLUSION: LGA pseudoaneurysm should be suspected in UGI bleeding if a large Dieulafoy's lesion-like structure or a pulsating bulge in the ulcer is found at the lesser curvature of the gastric body on endoscopy and if the patient has any intra-abdominal inflammatory disease.

BACKGROUND AND AIMS: As the incidence of duodenal neuroendocrine tumors (DNET) is steadily increasing, the role of endoscopic treatment for appropriate lesions is becoming more significant. We aimed to compare the outcomes according to lesion size and endoscopic mucosal resection (EMR) techniques for DNET treatment. PATIENTS AND METHODS: Patients who underwent endoscopic treatment for DNET between June 2000 and December 2019 were included. The clinicopathologic features and treatment outcomes were investigated by reviewing medical records. RESULTS: Overall, 104 cases underwent endoscopic resection for nonampullary DNET, including conventional EMR (n = 57), cap-assisted EMR (EMR-C, n = 19), and precut EMR (EMR-P, n = 28). The en bloc resection rates (100% vs. 94.7% vs. 96.4%) and histologic complete resection rates (45.6% vs. 52.6% vs. 57.1%) were not significantly different between the EMR, EMR-C, and EMR-P groups. The histologic complete resection rates were significantly higher in lesions < 10 mm than in lesions ≥ 10 mm (69.8% vs. 38.9%, P = 0.013). In lesions < 10 mm, perforation occurred more frequently in the modified EMR group than in the conventional EMR group (13.2% vs. 0.0%, P = 0.007). During the median follow-up period of 88.0 months, the recurrence-free survival (92.2% vs. 94.4% vs. 92.1%) and overall survival (98.0% vs. 88.1% vs. 100.0%) rates did not show significant differences between the EMR, EMR-C, and EMR-P groups. CONCLUSION: Conventional EMR and modified EMR are feasible and effective for the treatment of nonampullary DNET sized < 10 mm and limited to mucosal and submucosal layer. Additionally, endoscopists should be aware of the high risk of perforation in modified EMR.

BACKGROUND: Subepithelial tumor (SET) size is important in determining the treatment plan; however, size estimation for gastric SETs has not been well investigated. We aimed to investigate which method predicts SET size most accurately by retrospectively analyzing surgically removed SETs. METHODS: From January 2015 through June 2020, patients who underwent surgical gastric SET removal at Asan Medical Center, Seoul, Korea, were enrolled. SET sizes measured by pathologists and endoscopists were retrospectively reviewed. The reliability of SET size measurement by endoscopic ultrasonography (EUS) and endoscopy was calculated using intraclass correlation coefficient (ICC), with pathologic size as the gold standard. RESULTS: Overall, EUS was highly reliable (ICC 0.86, P < 0.001), and endoscopy was moderately reliable (ICC 0.75, P < 0.001). When analyzed according to SET location, endoscopy was highly reliable in the lesser curvature's lower third (ICC 0.86, P = 0.014), middle third (ICC 0.88, P < 0.001), and upper third (ICC 0.90, P < 0.001); as well as the anterior wall's middle third (0.84, P < 0.001) and the posterior wall's upper third (ICC 0.80, P < 0.001). EUS (ICC 0.96, P = 0.005) and endoscopy (ICC 0.95, P = 0.008) both were most reliable for lower-third posterior wall lesions, whereas endoscopy was unreliable for middle-third greater curvature lesions (ICC 0.41, P = 0.05). CONCLUSIONS: Both EUS and endoscopy were reliable methods for measuring gastric SET size, and overall, EUS was more reliable than endoscopy. In terms of SET location, EUS was consistently reliable, whereas endoscopy showed variable reliability. When measuring SET size by endoscopy, additional size measurements with EUS should be considered in certain locations.

BACKGROUND: Endoscopic submucosal dissection (ESD) is sometimes performed for early gastric cancer (EGC) which is not indicated for endoscopic resection (ER) in elderly patients considering old age and comorbidities. We aimed to compare outcomes between ESD and surgery in elderly patients with EGC that is not indicated for ER. METHODS: Elderly patients aged ≥ 75 years who underwent either ESD or surgery for EGC which was not indicated for ER between 2005 and 2015 were retrospectively investigated. RESULTS: Among a total of 294 patients, 59 (20.1%) and 235 (79.9%) patients underwent ESD and surgery as the initial treatment, respectively. The ESD group had smaller size of tumors (25 vs. 30 mm, p = .001) and higher rate of differentiated-type cancer than the surgery group had (88.1% vs. 60.9%, p = 0.001). With a median observation period of 91.8 months (range 11.6-198.1 months), 141 (48.0%) patients died: 25 (42.4%) and 116 (49.4%) patients in the ESD group and the surgery group, respectively. Overall survival and disease-free survival between the two groups had no significant differences (p = 0.982. p = 0.155, respectively). CONCLUSIONS: ESD may be an alternative option for EGC which is not indicated for ER in elderly patients aged ≥ 75 years, considering old age and comorbidity.

BACKGROUND: The likelihood of recurrence of gastric hyperplastic polyps (GHPs) following endoscopic resection and the need for long-term follow-up remain unknown. We, therefore, aimed to investigate the factors associated with the recurrence and cumulative incidence of GHPs over a 10-year period. METHODS: Between May 1995 and December 2020, 1,018 GHPs > 1 cm were endoscopically resected from 869 patients. Medical records of these patients were retrospectively reviewed and their clinical features and outcomes were assessed. Groups of GHPs with recurrence and those without recurrence group were compared, and univariate and multivariable analyses were performed to identify the potential risk factors for GHP recurrence. RESULTS: A total of 104 (12.0%) patients who underwent endoscopic removal of GHPs experienced recurrence. Compared to patients without recurrent GHPs, those with recurrent GHPs showed considerably larger median polyp size (28 mm vs. 14 mm, P < 0.001), a higher proportion of multiple polyps (41.3% vs. 29.3%, P = 0.020), polyps with lobulation (63.5% vs. 40.3%, P = 0.001), and exudate (63.5% vs. 46.8%, P = 0.001). Compared to the local recurrence (n = 52) group, the metachronous recurrence (n = 52) group had larger median polyp size (20 mm vs. 16 mm, P = 0.006) as well as higher rates of polyp lobulation (86.5% vs. 40.4%, P < 0.001) and exudate (82.7% vs. 44.4%, P = 0.001). After primary GHP excision, the cumulative incidence of recurrence was 7.2%, 12.7%, and 19.6% at 2 years, 5 years, and 10 years, respectively. CONCLUSION: The incidence of GHP recurrence following endoscopic excision increased as the follow-up period increased, especially in patients whose GHPs were large-sized, multiple, or characterized by surface exudates/lobulations.

BACKGROUND: Marginal ulcer bleeding (MUB) is a complication that can occur following several types of surgery. However, few studies exist on it. Therefore, this study aimed to compare the clinical outcomes of MUB with those of peptic ulcer bleeding (PUB). METHODS: Between January 2013 and December 2017, 5,076 patients underwent emergent esophagogastroduodenoscopy for suspected upper gastrointestinal bleeding. We retrospectively reviewed and analyzed the medical records of MUB and PUB patients and developed a propensity score matching (PSM) method to adjust for between-group differences in baseline characteristics with 1:2 ratios. Sex, age, body mass index (BMI), underlying diseases, and drugs were included as matching factors. RESULTS: A total of 64 and 678 patients were diagnosed with MUB and PUB, respectively, on emergent esophagogastroduodenoscopy, and 62 and 124 patients with MUB and PUB, respectively, were selected after PSM. Rebleeding was significantly higher in patients with MUB than in those with PUB (57.8% vs 9.1%, p < 0.001). Mortality caused by bleeding was higher in patients with MUB than in those with PUB (4.7% vs. 0.4%, p < 0.001). Multivariate analysis revealed that proton pump inhibitor (PPI) administration (odds ratio [OR], 0.14; 95% confidence interval [CI], 0.03-0.56; p = 0.011) after first bleeding was inversely correlated with MUB rebleeding. Large ulcer size (> 1 cm) (OR, 6.69; 95% CI, 1.95-27.94; p = 0.005) and surgery covering pancreas (OR, 3.97; 95% CI, 1.19-15.04) were independent risk factors for MUB rebleeding. CONCLUSIONS: MUB showed a severe clinical course than PUB. Therefore, MUB should be managed more cautiously, especially for large ulcers and pancreatic surgery. Prophylactic PPI administration may be helpful in reducing rebleeding in MUB.

BACKGROUND AND AIMS: In the efforts toward reducing bleeding-related mortality, it is crucial to determine the risk factors for rebleeding after endoscopic hemostasis in benign peptic ulcer (BPU). METHODS: Between 2013 and 2017, the medical records of 864 BPU patients were selected from 5076 who had undergone emergency endoscopy for suspected upper gastrointestinal bleeding. Patients who visited the emergency room or were hospitalized for other illnesses were selected. The primary end point was rebleeding within 30 days after initial endoscopy. The risk factors of rebleeding and subgroup analyses according to patient location were evaluated. RESULTS: Among 864 BPU bleeding patients, rebleeding after completion of BPU bleeding occurred in 140 (16.2%). Initial indicators of hypotension (OR 1.878, p = 0.005) and Forrest classes Ia (OR 25.53, p < 0.001), Ib (OR 27.91, p = 0.005), IIa (OR 21.41, p < 0.001), and IIb (OR 23.74, p < 0.001) were independent risk factors of rebleeding compared to Forrest class III, and being inpatients (OR 1.75, p = 0.01). Compared to the outpatients, the inpatients showed significantly higher rebleeding rates (25.6% vs 13.8%, p < 0.001), predictive bleeding scores, red blood transfusion counts, proportion of Forrest classes Ia, Ib, and IIb (p < 0.001), and overall mortality rates (68.8% vs 34.0%, p < 0.001). CONCLUSIONS: Patient location was a novel predictive factor of BPU rebleeding. Particularly, being an inpatient correlated with increased rebleeding. Furthermore, Forrest classes Ia, Ib, IIa, and IIb were predictive of rebleeding not only the included BPUs, but also in the inpatient or outpatient groups.

Few studies have focused on preoperative nutritional status of esophageal cancer patients eligible for upfront surgery. We aimed to investigate the association of preoperative nutritional status with prognosis of patients who undergo upfront surgery for esophageal cancer. A total of 274 patients who underwent upfront surgery for esophageal squamous cell carcinoma between January 2012 and December 2016 were eligible. Preoperative nutritional status was evaluated using prognostic nutritional index (PNI) scoring system, nutritional risk screening 2002 (NRS 2002), and controlling nutritional status. The median age was 63 years (interquartile range, 58-70) and 94.7% of patients were male. The pathological stages were Stage I-74.5% (204/274), Stage II-20.4% (56/274), and Stage III-5.1% (14/274). Multivariate analysis revealed that advanced stage, a low PNI, and a high NRS 2002 were independent predictors of overall survival. During median follow-up period of 55 mo, overall survival rates were lower in the high NRS 2002 group (P < 0.001). A high NRS 2002 score was associated with frequent postoperative complications, especially pneumonia and anastomosis site leakage (P = 0.003). The poor preoperative nutritional status with a high NRS 2002 is associated with postoperative complications as well as poor overall survival in patients with upfront surgery for esophageal cancer.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2022.2042573.

BACKGROUND/AIMS: We aimed to develop an endoscopic scoring system to evaluate gastric atrophy and intestinal metaplasia using narrow-band imaging (NBI) and near focus mode (NFM) to compare endoscopic scores with the Operative link for gastritis assessment (OLGA) and the Operative link for gastric intestinal metaplasia assessment (OLGIM). METHODS: A total of 51 patients who underwent diagnostic esophagogastroduodenoscopy were prospectively enrolled and endoscopic scoring using NBI and NFM was performed. Four areas (the lesser and greater curvatures of the antrum and the lesser and greater curvature side of the corpus) were observed and biopsies were taken. The degree of atrophy was scored from 0 to 2 according to the Kimura-Takemoto classification. The degree of intestinal metaplasia was scored from 0 to 4 according to the location and the extent of the intestinal metaplasia. RESULTS: The correlation coefficient for atrophy between the endoscopic and histologic scores was 0.70 (95% CI: 0.52-0.81 p < .001) and for intestinal metaplasia, it was 0.75 (95% CI: 0.60-0.85; p < .001). For atrophic gastritis, an endoscopic score >1 correlated with OLGA stage III and IV with a sensitivity, specificity, positive predictive value, negative predictive value, and agreement of 88, 74, 75, 87, and 80.4%, respectively, and for intestinal metaplasia, an endoscopic score >1 correlated with high OLGIM stage III and IV with 100, 59, 69, 100, and 78.4%, respectively. CONCLUSIONS: Endoscopic scoring for gastric atrophy and intestinal metaplasia using NBI-NFM likely correlates with histologic staging in Korea, a high-risk region for gastric cancer.

BACKGROUND: Although upper gastrointestinal (GI) neoplasms are not rare in patients with familial adenomatous polyposis (FAP), few studies have focused on them and the long-term outcomes of their treatment by endoscopy. Therefore, we aimed to investigate the prevalence and endoscopic treatment outcomes of upper GI neoplasms in patients with FAP. METHODS: Among 215 patients diagnosed with FAP between January 1991 and December 2019, 208 who underwent esophagogastroduodenoscopy were eligible. The clinical features and endoscopic treatment outcomes of upper GI neoplasms were retrospectively investigated and analyzed. RESULTS: Among the enrolled patients, 113 (54.3%) had one or more upper GI neoplasms: gastric adenoma (n = 34), gastric cancer (n = 7), nonampullary duodenal adenoma (n = 86), and ampullary adenoma (n = 53). Among patients with gastric neoplasms (n = 37), 24 (64.9%) underwent treatment (endoscopic treatment: 22, surgery: 2). No tumor-related mortality occurred during median follow-up of 106 months (interquartile range [IQR] 63-174). Endoscopic treatment was performed in 47 (54.7%) of 86 patients with nonampullary duodenal adenoma and in 32 (60.4%) of 53 patients with ampullary adenoma. No patient underwent surgery for duodenal neoplasms, and no tumor-related mortality occurred during median follow-up of 88 months (IQR 42-145). The proportion of patients with increased Spigelman stage at 2 years after the initial diagnosis or treatment was significantly higher in untreated group than in the group treated for duodenal neoplasms (27.3% vs. 0.0%, p = 0.001). CONCLUSION: Endoscopic surveillance in FAP patients is important for the detection and treatment of upper GI neoplasms in early stage. In particular, endoscopic therapy for duodenal neoplasms can reduce the severity of duodenal polyposis.

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.

BACKGROUND: Bismuth-containing quadruple therapy is an effective alternative first-line therapy for Helicobacter pylori infection. We evaluated the efficacy and safety of a modified twice-a-day bismuth quadruple regimen (BQT-2) with low-dose (1000 mg total) metronidazole as first-line therapy for the eradication of H pylori. MATERIALS AND METHODS: In this prospective pilot study, patients diagnosed with H pylori infection and naïve to eradication therapy were included. The modified BQT-2 therapy consisted of rabeprazole 20 mg, amoxicillin 1 g, metronidazole 500 mg, and tripotassium dicitrato bismuthate 600 mg (elemental bismuth 240 mg) twice daily, given 30 minutes before morning and evening meals for 14 days. H pylori eradication was assessed by 13 C-urea breath test conducted at least 4 weeks after therapy completion. RESULTS: In 66 patients who received the modified BQT-2 regimen, the compliance rate was 100% and the H pylori eradication rate was 77.3%. H pylori was successfully cultured in 50 (75.8%) patients. The resistance rates to metronidazole and clarithromycin were 30.0% and 22.0%, respectively. Eradication rates were not significantly different according to the resistance to metronidazole (metronidazole-susceptible: 74.3% [26/35], metronidazole-resistant: 73.3% [11/15]; P > .99). Most of the adverse events were mild, with 20 (30%) patients developing nausea, epigastric soreness, loose stool, asthenia, skin rash, dizziness, taste perversion, headache, or dyspepsia. CONCLUSIONS: Twice-a-day modified BQT-2 regimen with low-dose metronidazole was suboptimal as an alternative first-line therapy for eradicating H pylori, despite high patient compliance.

BACKGROUND AND AIMS: The prognosis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma is favorable, especially in the absence of lymph node metastasis (LNM). We investigated LNM incidence and location in superficial type gastric MALT lymphoma. METHODS: We performed a retrospective analysis of 450 patients newly diagnosed with gastric MALT lymphoma with tumor infiltration confined to the mucosa or submucosa as evidenced by endoscopic ultrasonography. LNM incidence and location were evaluated. RESULTS: Of the 450 patients, most patients (434, 96.4%) were initially LNM negative as confirmed by computed tomography (CT) scanning. Sixteen patients (3.6%) were LNM positive. There was no difference in clinical characteristics between the 2 groups except for the extent of lymphoma involvement and endoscopic findings. Among 41 patients undergoing abdominal/pelvic CT (APCT) only, LNM was detected in 1 (2.4%). There were 8 LNM cases among 238 patients undergoing both APCT and chest CT (3.4%). Among 171 patients undergoing APCT, chest CT, and neck CT, 7 cases of LNM were detected (4.1%). The detection rates for each CT were as follows: abdominal CT, 13/450 (2.9%); chest CT, 6/408 (1.5%); and neck CT, 1/171 (0.6%). Among 6 patients with chest CT-positive findings, 3 showed no evidence of LNM on APCT. CONCLUSION: LNM was an infrequent finding in gastric MALT lymphoma patients with tumor infiltration confined to the mucosa or submucosa. Besides endoscopy and endoscopic ultrasonography, APCT and chest CT are considered as optimal initial workup modalities in patients with assumed primary superficial gastric MALT lymphoma.

BACKGROUND: Ingested foreign objects frequently require emergency removal. This study aimed to investigate the clinical outcomes of endoscopic removal of foreign bodies from the upper gastrointestinal tract and the risk factors for adverse events. METHODS: Adults (> 18 years) who underwent endoscopic management of ingested foreign bodies at two centers, one inland and one on the coast, between January 2008 and December 2017 were eligible. Clinical characteristics and procedure-related outcomes were retrospectively reviewed. Patients were divided into two groups, based on whether the foreign bodies were sharp or blunt in shape. RESULTS: A total of 853 patients aged 19-96 years were analyzed. Ingestion of fish bones was more common in the coastal area, whereas ingestion of food boluses was more common in the inland area. The duration of impaction ranged from 1 h to over 1 month and was significantly longer in patients who ingested blunt than sharp foreign bodies (15 vs. 5 h, p < 0.001). Most (98.9%) foreign bodies were successfully removed. Adverse events occurred in 31.2 % of patients, including ulcers (4.0%) and perforations (3.3 %). Multivariate analysis showed that age (odds ratio [OR] 1.015, p = 0.012), sharp foreign bodies (OR 5.133, p < 0.001), location in the esophagus (OR 2.723, p = 0.018), and duration of impaction (OR 1.431, p < 0.001) were factors associated with adverse events. CONCLUSIONS: Early recognition and timely endoscopic removal of ingested foreign bodies, particularly in elderly patients and those with sharp foreign bodies, may improve clinical outcomes.
