RESUMO
BACKGROUND AND AIMS: When endoscopic retrograde cholangiopancreatography-guided biliary drainage is challenging, endoscopic ultrasound-guided biliary drainage (EUS-BD) can be used as an alternate treatment; however, this method requires operator expertise. Therefore, this study aimed to clarify the factors that are associated with a difficult EUS-BD. PATIENTS AND METHODS: Patients who successfully underwent EUS-BD were enrolled in this study. The patients were divided into the easy group and difficult group depending on whether the procedural time was more than 60 minutes, which was the cutoff value elicited from past reports. Patient characteristics and procedural factors were compared between the two groups. The factors associated with difficult procedures were also investigated. RESULTS: The patient characteristics were not significantly different between the easy group (n=22) and the difficult group (n=19). The diameter of the punctured bile duct was significantly different between the two groups. In the multivariate analysis, the diameter of the punctured bile duct was the only factor associated with a difficult EUS-BD (odds ratio 0.65, 95% confidence interval 0.46-0.91, P value=0.012). The cutoff value for the diameter of the punctured bile duct in predicting a difficult EUS-BD was 7.0 mm (area under the curve: 0.83, sensitivity 84.2%, specificity 86.4%). CONCLUSIONS: A nondilated bile duct might be a predictive factor for a difficult EUS-BD. For beginners of EUS-BD, the cutoff value for the punctured bile duct diameter found in this study, 7.0 mm, might become a barometer for puncture point selection.

INTRODUCTION: Sodium hyaluronate (SH) is a useful submucosal injectant for gastric endoscopic submucosal dissection (ESD). On the other hand, sodium carboxymethylcellulose (SCMC), which has high viscosity, has also been applied clinically. We evaluated the efficacy of SCMC compared to that of SH in gastric ESD. METHODS: A prospective randomized controlled trial was conducted to assess the efficacy of 1.0% SCMC as the injectant (SCMC group) compared to 0.4% SH (SH group) for ESD of gastric neoplasms. The primary end point was the procedure time of ESD. Secondary end points were treatment outcomes such as en bloc and R0 resection rates, number of hemostases, amount of injectant, ease of treatment (visual analog scale, 1-10 points), adverse events, and rate of ulcer healing 8 weeks after ESD. RESULTS: A total of 60 patients were enrolled between October 2014 and October 2018, and 30 patients were allocated in each group. The procedure time (mean ± SD, minutes) was not significantly different between the SCMC (74.7 ± 54.5) and SH groups (67.1 ± 41.4) (p = 0.547). Furthermore, there were no differences between the 2 groups in terms of en bloc and R0 resection rates, number of hemostases, amount of injectant, ease of treatment, and rate of ulcer healing. No serious adverse events were observed in either group. CONCLUSION: SCMC was comparable to SH in terms of procedure time, treatment outcome, and ease and safety of treatment in gastric ESD. Further studies are needed to demonstrate the differences between the 2 injectants.

OBJECTIVES: The aim of this study was to review the suitability of endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) for ruling out malignancy in autoimmune pancreatitis patients. METHODS: We retrospectively reviewed 40 autoimmune pancreatitis patients (type 1:37 patients; type 2: two patients; possible autoimmune pancreatitis: one patient) who received EUS-FNA. Among the 40 autoimmune pancreatitis patients, 34 were not histopathologically diagnosed with autoimmune pancreatitis by EUS-FNA, and they were followed up for more than 6 months in our hospital. Moreover, 14 pancreatic cancer patients who were not diagnosed by EUS-FNA were selected as a control group. These 14 patients constituted 3.9% of the 360 pancreatic cancer patients who received EUS-FNA. We evaluated the prognoses of the 34 autoimmune pancreatitis patients and the clinical differences between these 34 autoimmune pancreatitis patients and the 14 pancreatic cancer patients. RESULTS: All 34 autoimmune pancreatitis patients showed reduced pancreatic swelling. The main pancreatic duct dilation ( > 3 mm), the diameter of the main pancreatic duct, the capsule-like rim sign, and serum CA19-9 levels were significantly different between the autoimmune pancreatitis and pancreatic cancer patients (2.9% versus 69.2%, P < .01; 1.7 ± 1.6 mm versus 6.8 ± 5.0 mm, P < .01; 79.4% versus 0%, P < .01; 41.4 ± 79.0 U/mL versus 2079.1 ± 275.3 U/mL, P = .02). CONCLUSIONS: Almost all pancreatic cancers can be diagnosed by EUS-FNA. Furthermore, other clinical characteristics of pancreatic cancer undiagnosed by EUS-FNA were different from autoimmune pancreatitis undiagnosed by EUS-FNA. Endoscopic ultrasonography-guided FNA can be used to rule out malignancy in autoimmune pancreatitis patients.

BACKGROUND: Wisteria floribunda agglutinin-positive mac-2 binding protein (WFA+-M2BP) is an excellent biomarker for predicting hepatic fibrosis. We hypothesized WFA+-M2BP might be a serum biomarker for the diagnosis of chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC) with dense fibrosis. METHODS: In this study, we included 16 CP and 24 PDAC patients. Serum levels of WFA+-M2BP (cut-off index [COI]) were compared between the 2 groups. To confirm the cellular production of WFA+-M2BP, we investigated the presence of WFA+-M2BP in HEK293 cells, 3 established human PDAC cell lines and a recently generated human PDAC cell line derived from a liver metastasis (MDA-PATC53). The bio-physiological effects of MDA-PATC53 supernatant were evaluated. Finally, the difference in the expression of glycosylation enzymes between MDA-PATC53 and Panc-1 were analyzed by cDNA microarray. RESULTS: We found that the serum WFA+-M2BP level could distinguish the 2 groups. The median serum COI of WFA+-M2BP was 0.98 and 0.51 in PDAC and CP, respectively. Additionally, WFA+-M2BP positive PDACs were more frequently associated with metastatic lesions than the WFA+-M2BP negative PDACs (91.6% vs. 41.7%, P = 0.009). The MDA-PATC53 cells alone produced WFA+-M2BP. However, we found that MDA-PATC53 supernatant containing WFA+-M2BP (1.0 COI) did not alter the biological behavior of cancer cell lines. The results of cDNA microarray revealed that several glycosylation enzymes with pro-oncologic function were highly expressed in MDA-PATC53 compared to Panc-1. CONCLUSIONS: Serum WFA+-M2BP can be a useful biomarker for the diagnosis of PDAC and the prediction of disease progression since it potentially reflects altered pro-oncologic glycosylation enzymes.

OBJECTIVES: Contrast-enhanced harmonic endoscopic ultrasonography (CEH-EUS) has been used to diagnose solid pancreatic lesions (SPLs). The aim of this study was to investigate the efficacy of CEH-EUS-guided fine-needle aspiration (CEH-EUS-FNA) compared with that of conventional EUS-FNA for the diagnosis of SPLs. METHODS: Forty patients with solid pancreatic lesions who visited Fukushima Medical University between September 2013 and June 2014 were recruited for this prospective study. Twenty patients underwent CEH-EUS-FNA, and 20 patients underwent conventional EUS-FNA. The sampling rate, sensitivity, accuracy, and number of needle passes required to obtain sufficient samples were compared between the two groups. RESULTS: Patient characteristics, sampling rate, accuracy, and sensitivity were not significantly different between the two groups. The final diagnosis of patients who underwent CEH-EUS-FNA was pancreatic cancer in 19 and intraductal papillary mucinous carcinoma in one. Nineteen patients who underwent conventional EUS-FNA were finally diagnosed with pancreatic cancer and one was diagnosed as cancer of the common bile duct. There was a significant difference in the number of needle passes required. A sufficient sample was obtained on one needle pass in 60% (12/20) of CEH-EUS-FNA group compared with 25% (5/20) of the conventional EUS-FNA group. CONCLUSIONS: Fewer needle passes were required to obtain samples from solid pancreatic lesions using CEH-EUS-FNA than those required using conventional EUS-FNA. Therefore, CEH-EUS-FNA may be more efficient and safer than conventional EUS-FNA for the diagnosis of solid pancreatic lesions.

Treatment guidelines for esophageal squamous cell carcinoma (ESCC) with concomitant esophageal varices (EVs), which increase the risk of bleeding, are unavailable. A 66-year-old man with a history of total gastrectomy was admitted to the hospital owing to hematemesis. Emergency upper gastrointestinal endoscopy revealed variceal bleeding near the anastomosis between the esophagus and jejunum, and endoscopic clipping stopped the bleeding. Upper gastrointestinal endoscopy following hemostasis revealed four EVs and a two-thirds ESCC circumference. The ESCC depth was suspected to be up to the mucosa. The patient underwent intravariceal endoscopic injection sclerotherapy (EIS) for EVs, followed by paravariceal EIS. However, after these treatments, blood flow in the EVs just below the ESCC remained, and endoscopic resection of the ESCC was judged to be difficult to perform. Therefore, we prioritized EV treatment and performed a second EIS on the ESCC, followed by argon plasma coagulation (APC). APC was expected to not only solidify the EVs but also eliminate the ESCC existing in the mucosa. Finally, EVs and ESCC were treated by EIS and APC. EIS followed by APC may be useful for treating concurrent EVs and intramucosal ESCC in patients with liver cirrhosis when embolization of the EVs is ineffective.
RESUMO
On computed tomography scanning, a 63-year-old man with vomiting and anorexia was discovered to have a mass in the pancreatic body and a retroperitoneal mass extending to the right lobe of the liver. An esophagogastroduodenoscopy revealed an advanced gastric carcinoma in the middle gastric body, and a biopsy specimen revealed a poorly differentiated adenocarcinoma. The pancreatic and retroperitoneal masses were considered metastatic lesions of gastric cancer, and a biopsy was taken from the pancreatic lesion using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The histology of the EUS-FNA pancreatic specimen revealed atypical spindle-shaped cells and increased stromal collagen fibrosis, and liposarcoma was considered. Conversely, a percutaneous ultrasound-guided biopsy was taken for the retroperitoneal lesion, and the histology revealed that it was a dedifferentiated liposarcoma. On the basis of histopathological and imaging findings, the retroperitoneal liposarcoma was identified as the primary lesion, the pancreatic lesion as a metastasis of the primary liposarcoma, and the gastric carcinoma as an independent tumor. As far as we know, there have only been three reports of metastatic pancreatic liposarcoma diagnosed via EUS-FNA. In this case, the patient also had gastric cancer, and EUS-FNA was helpful in differentiating metastatic pancreatic tumors from gastric cancer.

The malignant gastrointestinal endometriosis transformation is represented by endometriosis-associated intestinal tumors. Endometrioid adenocarcinoma and clear cell adenocarcinoma are most common among the endometrial cancers of all organs. Only four cases of mixed serous carcinoma and large cell neuroendocrine carcinoma have been reported, and all these cases originated from the uterus. A 59-year-old woman with a month's history of bloody stools was admitted. She was stable until the hematochezia occurred but is 11 years post-hysterectomy. A circumferential type-3 advanced upper rectum tumor was seen on colonoscopy. Adenocarcinoma was revealed from the forceps biopsies of the type-3 tumor component. Computed tomography showed narrowed lumen with a thickened rectum wall, a continuing mass, and a component on the anorectal side. Swollen lymph nodes were observed around the rectum, but no distant metastatic lymph nodes or organs were found. To treat the lesion, rectal surgical resection with D3 lymph node dissection was performed. Histological examination revealed combined high-grade serous and large cell neuroendocrine carcinomas. Tumor was contiguous to the endometrium in the sub-serosa. Endometriosis was determined to be the origin of both carcinomas. Therefore, endometriosis-associated intestinal tumors should be included in the differential diagnosis when rectal tumors with cystic structures are found post-hysterectomy.

Endoscopic ultrasound-guided biliary drainage (EUS-BD) may prevent stent placement at the bile duct stricture. Therefore, whether a plastic stent (PS) or metallic stent (MS) should be used for EUS-BD remains to be undetermined. The present study aimed to clarify whether a PS or MS was more efficient for EUS-BD. Patients with malignant biliary obstruction who were successfully treated with EUS-BD were enrolled in the present study. The clinical characteristics, procedural outcomes and time to recurrent biliary obstruction (TRBO) were compared between patients treated with a PS (PS group) and patients treated with an MS (MS group). Consequently, 28 patients underwent PS placement and 11 patients underwent MS placement. In the PS group, 12 patients also underwent EUS-antegrade stenting (AGS) using an MS. The TRBO was not significantly different between the two groups (P=0.25). When the patients with AGS were excluded, the TRBO was significantly longer in the MS group than in the PS group (P=0.036). However, the TRBO was not significantly different between the patients in the MS group and those in the PS group who underwent AGS (P=0.61). In EUS-BD, MS is expected to be associated with a longer TRBO than PS. However, combining EUS-BD with AGS may help overcome the shorter TRBO associated with the use of PS.
RESUMO
It is unclear whether molnupiravir has a beneficial effect on vaccinated patients infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We here evaluated the efficacy of molnupiravir in patients with mild-to-moderate coronavirus disease 2019 (COVID-19) during the Omicron variant surge in Fukushima Prefecture, Japan. We enrolled patients with mild-to-moderate COVID-19 who were admitted to hospitals between January and April, 2022. Clinical deterioration after admission was compared between molnupiravir users (n = 230) and non-users (n = 690) after 1:3 propensity score matching. Additionally, we performed forward stepwise multivariate logistic regression analysis to evaluate the association between clinical deterioration after admission and molnupiravir treatment in the 1:3 propensity score-matched subjects. The characteristics of participants in both groups were balanced as indicated by covariates with a standardized mean difference of < 0.1. Regarding comorbidities, there was no imbalance between the two groups, except for the presence of hypertension, dyslipidemia, diabetes mellitus, and cardiac disease. The clinical deterioration rate was significantly lower in the molnupiravir users compared to the non-users (3.90% vs 8.40%; P = 0.034). Multivariate logistic regression analysis demonstrated that receiving molnupiravir was a factor for preventing deterioration (odds ratio 0.448; 95% confidence interval 0.206-0.973; P = 0.042), independent of other covariates. This real-world study demonstrates that molnupiravir contributes to the prevention of deterioration in COVID-19 patients after hospitalization during the Omicron variant phase.

A 49-year-old man was found to have an elevated lesion on esophagogastroduodenoscopy (EGD) for gastric cancer screening. This lesion had been noted in EGD 13 years earlier, but the patient had not received EGD since then. Endoscopy showed a relatively soft subepithelial lesion (SEL) in the gastric antrum. In addition, endoscopic ultrasonography (EUS) showed a 20-mm-sized, slightly non-uniform hypoechoic mass in the submucosa. Since the diagnosis could not be confirmed by mucosal biopsy, EUS-guided fine-needle aspiration (EUS-FNA) was performed. Hematoxylin-eosin staining of EUS-FNA samples revealed deposition of acidophilic unstructured materials. The structure was positive on Congo red staining, and green polarized light was also observed under a polarizing microscope. Moreover, it was resistant to potassium permanganate reaction, negative for serum amyloid A protein, positive for anti-λ chain antibody, and negative for anti-κ chain, anti-amyloid A, anti-transthyretin, and anti-ß2-microglobulin antibodies. Therefore, the lesion was diagnosed as AL-λ-type amyloidosis. No systemic amyloidosis findings were found; thus, the patient was finally diagnosed with localized gastric AL amyloidosis. If an SEL is seen without disease-specific endoscopic findings, amyloidosis should be included in the differential diagnosis, and EUS-FNA can contribute to obtaining tissue samples in such cases.

Porto-sinusoidal vascular liver disease (PSVD) is a disorder that can cause portal hypertension without liver cirrhosis. TAFRO syndrome is a systemic inflammatory disorder with a background of immunological abnormalities. We report a case of TAFRO syndrome complicated by PSVD with portal hypertension. A 39-year-old man developed refractory ascites and esophageal varices. Lymph node histology revealed multicentric Castleman disease-like features. Intravenous methylprednisolone and tocilizumab therapy improved ascites and renal dysfunction, but the patient developed severe infections. The diagnosis of TAFRO syndrome in patients complicated by PSVD with portal hypertension encourages the consideration of appropriate treatment for these patients.

METHODS: Twenty-six patients with UGI-SELs indicated for EUS-FNA were randomly assigned to the dry-first arm using the dry technique for the first two passes or the wet-first arm using the wet technique for the first two passes using a cross-over design with a ratio of 1 : 1. The primary endpoint was the cellularity score of the EUS-FNA specimens rated on a 4-point scale (0-3). The secondary endpoints were the factors influencing cellularity in each suction technique. RESULTS: The mean cellularity score was 1.65 ± 1.20 for the wet technique and 2.00 ± 0.98 for the dry technique (p = 0.068). Logistic regression analysis showed that higher cellularity may be related to the final diagnosis of gastrointestinal stromal tumors in the dry technique and the SEL location in the upper stomach in the wet technique. CONCLUSION: The wet EUS-FNA technique failed to show a potential for improved cellularity of specimens compared to the dry technique for UGI-SELs.
RESUMO
AIM: To investigate the location to which a pancreatic stent should be inserted to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). METHODS: Over a ten-year period at our hospital, 296 patients underwent their first ERCP procedure and had a pancreatic stent inserted; this study included 147 patients who had ERCP performed primarily for biliary investigation and had a pancreatic stent inserted to prevent PEP. We divided these patients into two groups: 131 patients with a stent inserted into the pancreatic head (head group) and 16 patients with a stent inserted up to the pancreatic body or tail (body/tail group). Patient characteristics and ERCP factors were compared between the groups. RESULTS: Pancreatic amylase isoenzyme (p-AMY) levels in the head group were significantly higher than those in the body/tail group [138.5 (7.0-2086) vs 78.5 (5.0-1266.5), P = 0.03] [median (range)]. No cases of PEP were detected in the body/tail group [head group, 12 (9.2%)]. Of the risk factors for post-ERCP hyperamylasemia (≥ p-AMY median, 131 IU/L), procedure time ≥ 60 min [odds ratio (OR) 2.65, 95%CI: 1.17-6.02, P = 0.02) and stent insertion into the pancreatic head (OR 3.80, 95%CI: 1.12-12.9, P = 0.03) were identified as independent risk factors by multivariate analysis. CONCLUSION: Stent insertion up to the pancreatic body or tail reduces the risk of post-ERCP hyperamylasemia and may reduce the risk of PEP.

We investigated whether serum microRNAs (miRNAs) could be diagnostic or prognostic markers in pancreatic ductal adenocarcinoma (PDAC). We first identified miRNAs showing altered expression in human pancreatic stellate cells (hPSCs) co-cultured with PDAC cells (Panc-1 and BxPC-3) as compared to hPSCs cultured alone. Among the miRNAs with altered expression, let-7d exhibited reduced expression in an in silico analysis of The Cancer Genome Atlas data. Inhibition of let-7d resulted in enhanced expression of fibrosis-related genes. We extracted serum miRNA from 45 PDAC patients and 42 healthy controls and quantified expression let-7d using digital PCR. Based on the level of let-7d expression, we were able to distinguish between PDAC patients and controls. Additionally, reduced let-7d expression correlated with poor overall survival. Thus, fibrosis-related miRNAs may be serum biomarkers for PDAC.
RESUMO
BACKGROUND AND STUDY AIMS: Proper sedation is necessary for the safe and satisfactory completion of endoscopic submucosal dissection (ESD) for early gastric cancer. This study was conducted as a comparative trial of efficacy and safety, comparing propofol-based sedation and midazolam-based sedation during ESD of early gastric cancer patients. PATIENTS AND METHODS: This study examined 64 lesions in 58 patients treated using ESD with midazolam plus pentazocine between July 2013 and January 2014 (group M) and 237 lesions in 216 patients treated by ESD using propofol plus pentazocine between February 2014 and December 2015 (group P). The two groups were compared in terms of the frequency of body movement during ESD as the primary outcome and in terms of the procedure time, en bloc resection rate, intraoperative change in cardiorespiratory dynamics, and postoperative awareness as the secondary outcomes. Body movement was defined as movement by a patient that required interruption of the procedure or restraint of the patient's body trunk, and addition of a sedative agent. RESULTS: The median frequency of body movement during ESD was significantly lower in group P (0 times) than in group M (3 times) ( P â<â0.001). No significant difference was found for the mean procedure time (117âmin in group P; 127âmin in group M). Although no significant difference was found in the incidence of hypoxemia, bradycardia, or bradypnea, the incidence of hypotension was significantly higher in group P (31.5â%) than in group M (6.9â%) ( P â=â0.004). Patients in group P had significantly higher postoperative awareness immediately after ESD and at 1 hour after ESD ( P â=â0.002 and 0.022, respectively). CONCLUSION: These results demonstrate the efficacy and safety of propofol-based sedation for gastric ESD.
RESUMO
AIM: To evaluate the efficacy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic head cancer when pushing (push method) or pulling the echoendoscope (pull method). METHODS: Overall, 566 pancreatic cancer patients had their first EUS-FNA between February 2001 and December 2017. Among them, 201 who underwent EUS-FNA for pancreatic head lesions were included in this study. EUS-FNA was performed by the push method in 85 patients, the pull method in 101 patients and both the push and pull methods in 15 patients. After propensity score matching (age, sex, tumor diameter, and FNA needle), 85 patients each were stratified into the push and pull groups. Patient characteristics and EUS-FNA-related factors were compared between the two groups. RESULTS: Patient characteristics were not significantly different between the two groups. The distance to lesion was significantly longer in the push group than in the pull group (13.9 ± 4.9 mm vs 7.0 ± 4.9 mm, P < 0.01). The push method was a significant factor influencing the distance to lesion (≥ median 10 mm) (P < 0.01). Additionally, tumor diameter ≥ 25 mm (OR = 1.91, 95%CI: 1.02-3.58, P = 0.043) and the push method (OR = 1.91, 95%CI: 1.03-3.55, P = 0.04) were significant factors contributing to the histological diagnosis of malignancy. CONCLUSION: The pull method shortened the distance between the endoscope and the lesion and facilitated EUS-FNA of pancreatic head cancer. The push method contributed to the histological diagnosis of pancreatic head cancer using EUS-FNA specimens.

In this study, we determined the efficacy of the cell death biomarker cytokeratin 18 for diagnosing biliary tract cancer (BTC). We recruited 36 patients with BTC (Malignant group) and 45 patients with benign biliary tract disease (Benign group) for this study. We used M30 and M65 as cell death biomarkers. M30 levels indicate apoptosis, and M65 levels indicate both apoptosis and necrosis. M30 and M65 levels were significantly higher in the Malignant group than in the Benign group (142.4 ± 117.0 vs 48.9 ± 71.2 U/l, P < 0.001; 1513.3 ± 837.4 vs 882.2 ± 831.2 U/l, P = 0.001). The diagnosability of M30 was the highest of the four markers (CEA, CA19-9, M30, M65) (cut-off value: 74.429 U/l, sensitivity: 72.2%, specificity: 77.1%, AUC: 0.771). The sensitivity of M30 (cut-off value: 74.429 U/l) was significantly higher than that of biliary cytology (76% (19/25) vs 12% (3/25), P < 0.001), and the accuracy of M30 was significantly higher than that of biliary cytology (78.3% (36/46) vs 52.2% (24/46), P = 0.015). The sensitivity of M30 (cut-off value: 74.429 U/l) was significantly higher than that of biliary cytology and brush cytology (72.4% (21/29) vs 24.1% (7/29), P < 0.001). In conclusion, cell death biomarkers were increased in patients with BTC, and M30 could efficiently diagnose BTC.

Allgrove syndrome, also known as Triple A syndrome, is a rare autosomal recessive genetic disease characterized by three signs: esophageal achalasia, adrenocorticotropic hormone refractoriness, and alacrima. A 31-year-old male presented to our hospital for treatment of difficulty swallowing caused by esophageal achalasia. Because he had complicating alacrima, a neurologic disease, and a family history of consanguineous marriage, a genetic neurologic disease was suspected. Then, a mutation in the achalasia-addisonianism-alacrima syndrome gene was identified. With the diagnosis of Allgrove syndrome, a per-oral endoscopic myotomy (POEM) was performed for esophageal achalasia. After the POEM, the symptoms and the esophageal pressure findings ameliorated quickly, with no recurrence noted throughout a follow-up of more than 1 year.

Objective Due to the Great East Japan Earthquake, which occurred in March 2011, many residents of Fukushima Prefecture were affected by a radiation accident in addition to suffering loss or damage from the earthquake and the subsequent tsunami. The aim of this study was to evaluate the actual condition of patients with peptic ulcers related to the disaster. Methods Patients with peptic ulcers at six hospitals in three different regions of Fukushima Prefecture during the two months following the disaster and the corresponding period of the year before and the year after the disaster were enrolled in this study. Changes by period and region in the number of esophagogastroduodenoscopy (EGD) examinations and the number of peptic ulcer patients were evaluated as the primary endpoints. Changes in the frequencies of hemorrhagic ulcers were evaluated by period and by region as secondary endpoints. Results The numbers of EGDs and peptic ulcer cases compared to the previous year decreased in 2011 and then increased in 2012. However, the ratio of hemorrhagic ulcers to peptic ulcers was higher in 2011 (51.9%) than in 2010 (38.1%) and 2012 (31.1%), and the 2011 hemorrhagic ulcer ratio was the highest at 63.6% in the coastal area. Regarding bleeding cases during 2011, the rate at 1 month after the disaster (64.1%) was higher than the rate at 2 months after the disaster (40.5%) (p=0.033). Conclusion The number of patients with peptic ulcers did not increase immediately following the disaster in Fukushima Prefecture. However, the rate of bleeding patients increased soon after the disaster, especially in the coastal area.
