RESUMEN
Background and Aim: Endoscopic ultrasound shear wave elastography (EUS-SWE) can facilitate an objective evaluation of pancreatic fibrosis. Although it is primarily applied in evaluating chronic pancreatitis, its efficacy in assessing early chronic pancreatitis (ECP) remains underinvestigated. This study evaluated the diagnostic accuracy of EUS-SWE for assessing ECP diagnosed using the Japanese diagnostic criteria 2019. Methods: In total, 657 patients underwent EUS-SWE. Propensity score matching was used, and the participants were classified into the ECP and normal groups. ECP was diagnosed using the Japanese diagnostic criteria 2019. Pancreatic stiffness was assessed based on velocity (Vs) on EUS-SWE, and the optimal Vs cutoff value for ECP diagnosis was determined. A practical shear wave Vs value of ≥50% was considered significant. Results: Each group included 22 patients. The ECP group had higher pancreatic stiffness than the normal group (2.31 ± 0.67 m/s vs. 1.59 ± 0.40 m/s, p < 0.001). The Vs cutoff value for the diagnostic accuracy of ECP, as determined using the receiver operating characteristic curve, was 2.24m/s, with an area under the curve of 0.82 (95% confidence interval: 0.69-0.94). A high Vs was strongly correlated with the number of EUS findings (rs = 0.626, p < 0.001). Multiple regression analysis revealed that a history of acute pancreatitis and ≥2 EUS findings were independent predictors of a high Vs. Conclusions: There is a strong correlation between EUS-SWE findings and the Japanese diagnostic criteria 2019 for ECP. Hence, EUS-SWE can be an objective and invaluable diagnostic tool for ECP diagnosis.
RESUMEN
Background and Aim: Elobixibat is a triple mode of action laxative that increases water secretion into the colon, promotes colonic motility, and reestablishes the defecation desire. This study aims to evaluate the effectivity and safety of elobixibat in chronic constipation (CC) patients refractory to conventional laxatives. Methods: A single-center retrospective observational study was conducted in refractory CC patients diagnosed according to the Rome IV criteria and received elobixibat between April 2018 and June 2022 at Osaka Saiseikai Nakatsu Hospital. Data were collected for spontaneous bowel movement (SBM), Bristol stool form scale (BSFS) scores, abdominal symptoms, and adverse events. Results: Eligible 311 patients were selected for the analysis. Two-week Elobixibat treatment significantly increased SBM (times/week) from 2.9 ± 1.9 to 4.3 ± 1.9 (P < 0.0001). The BSFS score improved significantly from 3.2 ± 1.7 to 4.4 ± 1.4 (P < 0.0001). The percentages of patients with hard stool were decrease and that with normal stools were increase. Improvements in abdominal symptoms (sensation of incomplete bowel evacuation, straining, abdominal pain and distention, and difficulty defecating) were also significant (P < 0.05). These constipation symptoms were improved irrespective of patient characteristics or previous laxatives. The 43.9% of previous laxatives were discontinued at the start of or after starting elobixibat treatment. A few adverse events were observed, elobixibat was well tolerated. Conclusion: Elobixibat was effective in patients who were refractory to other laxatives, irrespective of previous therapy or patient characteristics. Elobixibat may contribute to resolving polypharmacy with single mode of action laxatives.

Background/Aims: Endoscopic self-expandable metal stent (SEMS) placement is currently the standard technique for treating unresectable malignant distal biliary obstructions (MDBO). Therefore, covered SEMS with longer stent patency and fewer migrations are required. This study aimed to assess the clinical performance of a novel, fully covered SEMS for unresectable MDBO. Methods: This was a multicenter single-arm prospective study. The primary outcome was a non-obstruction rate at 6 months. The secondary outcomes were overall survival (OS), recurrent biliary obstruction (RBO), time to RBO (TRBO), technical and clinical success, and adverse events. Results: A total of 73 patients were enrolled in this study. The non-obstruction rate at 6 months was 61%. The median OS and TRBO were 233 and 216 days, respectively. The technical and clinical success rates were 100% and 97%, respectively. Furthermore, the rate of occurrence of RBO and adverse events was 49% and 21%, respectively. The length of bile duct stenosis (<2.2 cm) was the only significant risk factor for stent migration. Conclusions: The non-obstruction rate of a novel fully covered SEMS for MDBO is comparable to that reported earlier but shorter than expected. Short bile duct stenosis is a significant risk factor for stent migration.
RESUMEN
BACKGROUND: There is no consensus on the necessity of endoscopic sphincterotomy (ES) to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) after endoscopic stenting in patients with malignant biliary obstruction. We investigated the incidence of PEP after endoscopic biliary stenting for malignant biliary obstruction with or without ES in a multicenter prospective cohort study. METHODS: We enrolled 807 patients who underwent endoscopic biliary stenting for malignant biliary obstruction with a native papilla at 36 hospitals between April 2017 and March 2018. The incidence of PEP in patients with or without ES was compared for subgroups based on stent type, placement method, and patient background. Univariate and multivariate analysis was performed to investigate the incidence of PEP in all stenting patients. RESULTS: Plastic and metal stents (MS) were inserted in 598 and 209 patients, respectively. The incidence of PEP in patients with or without ES was 7.9% and 7.4%, respectively among all stenting patients. The incidences of PEP with or without ES in plastic stent insertion patients, patients with MS insertion, stent insertions across the papilla, stent insertions across the papilla in patients without main pancreatic duct obstruction, and fully covered MS insertions across the papilla were compared. There was no overall significant difference in the incidence of PEP between those with or without ES. Multivariate logistic regression analysis for the incidence of PEP in all stenting patients revealed obstruction of the main pancreatic duct at the pancreatic head and epinephrine spraying on the papilla were significant factors; there was no significant difference in the incidence of PEP between patients with or without ES. CONCLUSION: Endoscopic sphincterotomy may not contribute to the prevention of PEP after endoscopic biliary stenting for malignant biliary obstruction, even in cases of insertion with a fully covered MS across the papilla.

BACKGROUND AND AIM: Recombinant thrombomodulin (rhTM) is potentially effective in the treatment of disseminated intravascular coagulation (DIC). Several studies related to drugs for the treatment of acute cholangitis have shown negative results in improvement of overall survival (OS) with rhTM. The aim of this multicenter study was to evaluate the clinical effectiveness of rhTM in patients with acute cholangitis and sepsis-induced DIC who underwent biliary drainage. METHODS: A total of 284 consecutive patients, who were complicated with sepsis-induced DIC due to severe acute cholangitis, were included (rhTM group, n = 173; non-rhTM, n = 111) in this study. The primary outcome was the DIC resolution rate at 7 days after starting treatment. The 28-day survival rate was secondarily evaluated. RESULTS: DIC scores in the rhTM group improved significantly compared with the non-rhTM group on day 7 (P = .020). According to multivariate analysis, etiology of cholangitis (malignant, HR 2.28), rhTM (non-administration, HR 4.13), and DIC score (≥5, HR 2.46) were significant factors associated with failed DIC resolution on day 7. Propensity score matching created 103 matched pairs. Survival rate at day 28 was significantly higher in rhTM group (94.3%) compared with non-rhTM group (82.6%; P = .048) after propensity score matching. rhTM (non-administration, HR 2.870), DIC score (≥5, HR 2.751), and APACHE II score (≥20, HR 9.310) were significant factors associated with decreasing survival rate at day 28. CONCLUSION: In conclusion, rhTM seemed to improve patient survival, but future studies should only include patients with benign or malignant disease and should be performed according to APACHE II scores.

Background and study aims Several studies have reported that pathological horizontal margin evaluation cannot be diagnosed in cold snare polypectomy (CSP) specimens. We conducted a prospective randomized controlled trial to determine the efficacy of pasting CSP specimens on paper for pathological horizontal margins. Patients and methods This was a single-center, prospective study conducted at Osaka Saiseikai Nakatsu Hospital. In this study, the indications for CSP were adenomas ≤â10âmm. Colorectal polyps resected by CSP were randomized to the pasting and non-pasting groups after exclusion of fragmented specimens, and the extended CSP specimens pasted on paper were formalin-fixed in the pasting group.âThe primary endpoint was rate of unclear horizontal margins after CSP. Results A total of 216 CSP specimens were analyzed. The rate of unclear horizontal margins was significantly lower in the pasting group than in the non-pasting group (15.1â% vs 33.6â%, P â=â0.002). CSP specimen pasting significantly reduced the rate of unclear horizontal margins. On multivariate analysis, non-pasting group (odds ratio [OR], 2.69; 95â% confidence interval [CI], 1.38-5.41; P â=â0.003) and right colon (OR, 1.98; 95â%CI, 1.01-4.01; P â=â0.047) were independent risk factors for unclear horizontal margins in CSP specimens. Conclusions Pasting the extended specimen is important for accurate pathological examination after CSP.
RESUMEN
This study examined the long-term maintenance rate after inducing remission by intensive granulocyte/monocyte adsorptive apheresis (GMA) without use of corticosteroids (CS) and GMA re-treatment efficacy in the same patients upon relapse with ulcerative colitis. Patients who achieved clinical remission and mucosal healing (MH) by first-time intensive GMA (first GMA) without CS were enrolled. The cumulative non-relapse survival rate up to week 156 was calculated. Patients with relapse during the maintenance period underwent second-time intensive GMA (second GMA) without CS. Clinical remission and MH rates following second GMA were compared to those following first GMA in the same patients. Of the 84 patients enrolled, 78 were followed until week 156 and 34 demonstrated relapse. The cumulative non-relapse survival rate by week 156 was 56.4%. Clinical remission and MH rates after second GMA did not differ from those after first GMA in the same patients (week 6: clinical remission, 100% vs 88.4%, pâ =â 0.134; MH, 100% vs 84.8%, pâ =â 0.074). In conclusion, MH induction by intensive GMA without use of CS in ulcerative colitis patients contributes to subsequent long-term clinical remission maintenance. GMA re-treatment efficacy was comparable to that of first GMA in the same patients who had relapse.
RESUMEN
Objectives: The endoscopic bilateral stent-in-stent (SIS) deployment is a challenging procedure. Such difficulty is mainly caused by sticking of the tip of the delivery sheath into the self-expandable metal stents (SEMSs) mesh, requiring an additional dilating procedure. Herein, we assessed the clinical results of using cross-wired metal stent for endoscopic bilateral SIS deployment (BONASTENT M-Hilar) in patients with malignant hilar biliary obstruction (MHBO) in both high-volume and non-high-volume centers. Methods: We prospectively enrolled consecutive patients with MHBO between February 2016 and December 2018 at eight centers. Results: Forty-six patients were enrolled during the study period. The proportions of technical success were 93.5% (43/46) and clinical success (CS) on intention-to-treat and per-protocol analyses were 91.3% (42/46) and 93.0% (40/43), respectively. The proportion of an additional dilating procedure during the primary procedure was 50.0% (23/46). Recurrent biliary obstruction (RBO) on intention-to-treat analysis occurred in 32.6% (15/46) of cases. Almost all of the events were caused by stent ingrowth (14/15). The median survival time and time to RBO were 255 and 349 days, respectively. The probability of stent patency at 3, 6, and 12 months was 86.5%, 63.9%, and 47.6%, respectively. Conclusions: The cross-wired metal stent had excellent technical and CS, although non-high-volume centers were included in this study (UMIN000021441).
RESUMEN
BACKGROUND/PURPOSE: The purpose of the present study was to investigate the possibility of reducing clinical impacts of acute necrotic collection (ANC) on patients with acute pancreatitis (AP) using recombinant human soluble thrombomodulin (rTM). METHODS: In this retrospective multicenter study, 233 consecutive AP patients with ANC and acute peripancreatic fluid collection (APFC) from 2012 to 2016 were enrolled. To assess clinical impacts of ANC, severity on admission (JPN score, JPN CT grade, and Modified CT severity index), development of walled-off necrosis (WON), imaging costs for follow-up, and mortality were recorded. Finally, we investigated whether rTM could reduce the clinical impacts, adjusting the severity using propensity analysis with Inverse probability of treatment weighting. RESULTS: Patients with ANC developed WON with higher ratio than APFC (58/98 [59.2%] vs 20/135 [14.8%], OR = 8.3, P < .01]. Severity on admission and imaging costs for follow-up in ANC patients were significantly higher than those in APFC (P < .01). However, regarding mortality, there was no significant difference between patients with ANC and APFC (P = .41). Adjusting severity, it was revealed that rTM administration significantly reduced the risk of ANC developed WON (OR = 0.23, P = .01). CONCLUSIONS: While ANC had a higher clinical impact than that of APFC, we found that early administration of rTM may reduce the impact.

INTRODUCTION: Lubiprostone is an effective treatment of chronic constipation (CC). However, as with other stimulant or osmotic laxatives, adverse events (AEs) can make it difficult to continue treatment. This article investigates AE risk factors associated with lubiprostone. METHODS: We retrospectively analyzed all 1,338 Japanese patients with CC treated at our hospital from October 2013 to July 2017. All patients were diagnosed with constipation as defined by the Roma III criteria. Enrolled patients received lubiprostone orally (24 or 48 µg daily), after which we investigated the incidence of AEs. The causative factors for diarrhea and nausea, the most common AEs, were examined by the backward logistic regression model. RESULTS: Two hundred eight (15.5%) experienced at least 1 AE. No serious AEs were associated with the study drug. The AEs reported by >1% of patients overall were diarrhea (6.1%) and nausea (4.2%). We performed a multivariate logistic regression using a backward variable selection method to investigate AE risk factors. Factors associated with higher incidence of diarrhea were patient age of 65 years or more (odds ratio: [95% confidence interval]; p value) (2.09: [1.05-4.16]; 0.035). Factors associated with greater likelihood of nausea included female gender (1.99: [1.10-3.61]; 0.023), and the chief complaint was a patient complaining of abdominal pain and fullness (2.07: [1.01-4.22]; 0.046). CONCLUSIONS: Understanding AE risk factors can help avoid unnecessary AEs and promote more effective treatment.

BACKGROUND: Surgical resection of intraductal papillary mucinous neoplasm (IPMN) is strongly recommended for patients exhibiting high-risk stigmata (HRS). However, determining surgical indications for elderly patients with comorbidities is challenging, as clinical outcomes are not well characterized. This multicenter observational study elucidated the clinical outcomes of patients with IPMN exhibiting HRS who did not undergo surgery. METHODS: This study enrolled 101 IPMN patients exhibiting HRS with follow-up observations at 11 hospitals in Japan (2011-2016). The median observation period was 37 months (maximum: 86 months). Primary outcomes were estimated 5-year overall survival (OS) and disease-specific survival (DSS). Survival was also stratified based on HRS features. RESULTS: Of 101 patients, 32 (31.7%) had the main pancreatic duct (MPD) measuring ≥ 10 mm and 80 (79.2%) had mural nodules measuring ≥ 5 mm. The estimated 5-year OS and DSS were 74% and 91%, respectively. In the stratified analysis, the co-presence of MPD ≥ 10 mm and mural nodules ≥ 5 mm or mural nodule ≥ 10 mm were related to worse 5-year DSS (MPD ≥ 10 mm and mural nodules ≥ 5 mm vs other characteristics: 60% vs 95%, log-rank test: p = 0.049; mural nodules ≥ 10 mm vs < 10 mm: 77% vs 95%, log-rank test: p = 0.003). CONCLUSIONS: The estimated 5-year DSS of conservatively managed IPMN patients with mural nodules and main duct dilation was 91%. Only IPMN patients with plural HRS or large nodule formation might have an increased mortality risk. This is an important insight that can help facilitate appropriate clinical decision-making, especially in the elderly or high-surgical risk IPMN patients.

BACKGROUND: Vonoprazan, a potassium-competitive acid blocker, is used for acid-related diseases. Occasionally, small white protrusions called "stardust" gastric mucosa have been detected in the stomachs of some patients taking vonoprazan. AIMS: To determine the incidence of, and risk factors for, stardust gastric mucosa potentially induced by vonoprazan METHODS: In this study, we enrolled 19 503 patients who underwent endoscopy at our hospital between 2016 and 2019. Using propensity score matching, we retrospectively compared patients who received and did not receive vonoprazan. The two groups were matched for age, sex, history of proton pump inhibitor use, and atrophic gastritis. RESULTS: After 1:1 propensity score matching, each group comprised 2516 patients. Stardust gastric mucosa was detected significantly more often in the stomachs of patients receiving vonoprazan than those who had not received vonoprazan (4.9% vs 0.2%, P < 0.001). Its location was 70.7% in the upper third of the stomach, 29.3% in the middle third and none in the lower third. Histologically, this lesion had a mucus pool within a dilated duct surrounded by flattened glandular epithelium. The cumulative incidence rate of stardust gastric mucosa at 1, 2 and 3 years was 4.6%, 16.5% and 26.2%, respectively. The factors independently associated with the presence of stardust gastric mucosa were >205 days of vonoprazan oral intake (odds ratio [OR]: 6.99, 95% confidence interval [CI]: 4.60-10.88) and female sex (OR: 1.75, 95% CI: 1.20-2.58). CONCLUSIONS: Stardust gastric mucosa appeared more frequently in the stomachs of patients taking vonoprazan.

OBJECTIVE: Stenting is an established endoscopic therapy for malignant gastric outlet obstruction (mGOO). The choice of stent (covered vs uncovered) has been examined in prior randomised studies without clear results. DESIGN: In a multicentre randomised prospective study, we compared covered (CSEMS) with uncovered self-expandable metal stents (UCSEMS) in patients with mGOO; main outcomes were stent dysfunction and patient survival, with subgroup analyses of patients with extrinsic and intrinsic tumours. RESULTS: Overall survival was poor with no difference between groups (probability at 3 months 49.7% for covered vs 48.4% for uncovered stents; log-rank for overall survival p=0.26). Within that setting of short survival, the proportion of stent dysfunction was significantly higher for uncovered stents (35.2% vs 23.4%, p=0.01) with significantly shorter time to stent dysfunction. This was mainly relevant for patients with extrinsic tumours (stent dysfunction rates for uncovered stents 35.6% vs 17.5%, p<0.01). Subgrouping was also relevant with respect to tumour ingrowth (lower with covered stents for intrinsic tumours; 1.6% vs 27.7%, p<0.01) and stent migration (higher with covered stents for extrinsic tumours: 15.3% vs 2.5%, p<0.01). CONCLUSIONS: Due to poor patient survival, minor differences between covered and uncovered stents may be less relevant even if statistically significant; however, subgroup analysis would suggest to use covered stents for intrinsic and uncovered stents for extrinsic malignancies.

INTRODUCTION: Elobixibat is a new laxative, but its efficacy and adverse events (AEs) are insufficiently examined compared with those of other laxatives. Hence, by propensity score (PS) matching, we compared the effects and AEs between elobixibat and lubiprostone. METHODS: We retrospectively analyzed 1,887 Japanese patients with chronic constipation (CC) treated at our hospital between October 2013 and April 2020. Enrolled patients were divided into three treatment groups, namely, elobixibat (10 mg daily) (E10 group, n = 293), lubiprostone (24 µg daily) (L24 group, n = 772), and lubiprostone (48 µg daily) (L48 group, n = 822), as their first treatment. We then investigated the changes on the weekly average number of spontaneous bowel movements, stool consistency scores (SCSs), and AEs starting from the baseline until the end of the 2-week treatment. To adjust for patients' background, we performed one-to-one nearest neighbor matching without replacement between elobixibat- and lubiprostone-treated patients according to the individual estimated PSs. RESULTS: After treatment, for SCSs, both the L24 and L48 groups significantly improved compared with the E10 group (p < 0.05), but their stools were soft (Bristol Stool Form Scale: 4.8). Notably, the E10 group had less frequent AEs than the L24 group (26 [9.0%] vs. 43 [14.8%], p = 0.03). Particularly, nausea was significantly less in the E10 group than that in the L48 group (2 [0.7%] vs. 7 [2.4%], p = 0.01). CONCLUSION: Elobixibat is a beneficial drug for patients with mildly symptomatic CC and is safe to use, given its few AEs.

Pyogenic granulomas (PG) are lobular capillary hemangiomas mostly found in the mucous membranes of the skin and oral cavity, and rarely occur in the gastrointestinal tract. Here we describe a case of an 84-year-old patient with alcoholic cirrhosis who presented with persistent melena and progressive anemia. Endoscopy showed esophageal varices and he underwent endoscopic variceal ligation (EVL) with transient resolution of anemia. However, due to worsening anemia, he underwent capsule endoscopy that revealed a bleeding tumor in the small intestine. We performed double-balloon endoscopy and found a 7-mm polyp with a white coat located in the jejunum and resected it at a later date. Histological characteristics led to the diagnosis of PG, and the patient's melena and anemia subsequently improved.

BACKGROUND AND AIM: Esophageal endoscopic submucosal dissection (ESD) is often technically difficult due to intraoperative body movements. The level of sedation can be increased to suppress body movements, but this may not be successful in all cases. Using local analgesics for submucosal injection during ESD may aid in conscious sedation. This study evaluated the feasibility of the lidocaine injection method (LIM) during esophageal ESD. METHODS: Twenty-nine patients with superficial esophageal cancer were enrolled in this study at Osaka Saiseikai Nakatsu Hospital, and 1% lidocaine + 0.4% hyaluronate sodium was injected into the submucosa underneath the lesion during esophageal ESD. The main outcome was body movements that disturbed the procedure. RESULTS: Most patients were male (90%), with a median age of 70 years (interquartile range [IQR]: 66-75 years old), and the median lesion size was 17 mm (IQR: 12-21 mm). The median injection volume of lidocaine was 70 mg (IQR: 55-79 mg). All lesions were successfully removed en bloc. In all cases, there were no body movements that disturbed the procedure. Regarding adverse events of sedation, five patients (17%) had hypotension, four patients (14%) had bradycardia, and seven patients (24%) had hypoxemia during ESD. Convulsions or arrhythmia as adverse events associated with lidocaine were not observed. CONCLUSIONS: Esophageal ESD with LIM did not cause body movements that disturbed the procedure. LIM may help create a stable conscious sedation method for esophageal ESD.
RESUMEN
BACKGROUND AND AIMS: Histologic diagnosis of autoimmune pancreatitis (AIP) using EUS-guided FNA (EUS-FNA) is difficult. To address this issue, new fine-needle biopsy (FNB) needles were recently developed. Here, we prospectively evaluated 2 newly designed EUS-FNB needles for histologic evaluation in patients with type 1 AIP. METHODS: This was a prospective, randomized, multicenter trial comparing biopsy specimens obtained with a 22-gauge Franseen needle or a 20-gauge forward-bevel needle in patients with suspected type 1 AIP. AIP was diagnosed according to international consensus diagnostic criteria. The primary endpoint was the sensitivity of EUS-FNB needles, and secondary endpoints were the amount of specimen obtained, histology of the pancreas based on evaluation of lymphoplasmacytic sclerosing pancreatitis (LPSP), and contribution of histologic findings to the diagnosis of AIP. RESULTS: One hundred ten patients were randomly assigned to the Franseen group (22-gauge Franseen needle) or the forward-bevel group (20-gauge forward-bevel needle). EUS-FNB sampling was successful in all patients. Nine patients were excluded because of diagnoses other than AIP. Compared with the forward-bevel needle, the Franseen needle obtained a significantly greater number of high-power fields. Of 101 patients, 39 patients (78%) in the Franseen group and 23 patients (45%) in the Forward-bevel group were diagnosed with level 1 or 2 LPSP (P = .001). Thirty-six patients could not be diagnosed with type 1 AIP without EUS-FNB specimen results. CONCLUSIONS: The 22-gauge Franseen needle should be routinely used for histologic diagnosis of type 1 AIP. (Clinical trial registration number: UMIN 000027668.).

A 67-year-old Japanese man with alcoholic cirrhosis underwent esophagogastroduodenoscopy (EGD), which revealed a 15-mm elevated lesion on the esophagogastric junction (EGJ). Endoscopic findings suggested that the lesion was an intramucosal cancer present on the esophageal varices. The location of the lesion at EGJ caused difficulties in endoscopic injection sclerotherapy and endoscopic variceal ligation for esophageal varices before esophageal endoscopic submucosal dissection (ESD). Direct varices coagulation treatment was therefore selected during ESD. Coagulation of bared varices with hemostatic forceps after mucosal incision enabled performing ESD without serious bleeding. 2 months afterwards, the patient underwent EGD, with no esophageal varices or carcinoma recurrence. Direct varices coagulation was effective for ESD of Barrett adenocarcinoma with esophageal varices.

BACKGROUND: Chronic pancreatitis (CP) is a fibro-inflammatory disease of the pancreas. Early diagnosis and intervention, before CP becomes established and irreversible, are essential to improve the long-term outcomes. The world's first diagnostic criteria for early CP were proposed in Japan in 2009, but their clinical utility remains elusive. This study aimed to clarify whether patients with early CP progress to definite CP. METHODS: This is a multicenter, prospective study. Patients diagnosed as having early CP according to the Japanese diagnostic criteria were prospectively followed for 2 years. Clinical profiles including symptoms, drinking and smoking status, laboratory data, imaging findings and treatments were analyzed. RESULTS: Among the 83 patients who completed the 2-year follow-up period, four (4.8%) patients progressed to definite CP. The diagnosis of 48 (57.8%) patients was unchanged, and that of 31 (37.3%) patients was downgraded. All the four progressive patients were male, alcohol-related, smokers (3 current and 1 ever), and continued drinking. Comparison of the clinical profiles between the progression group (n = 4) and non-progression group (n = 79) revealed that etiology (alcohol-related), smoking status and presence of acute pancreatitis episodes were associated with the progression to definite CP. CONCLUSIONS: The Japanese diagnostic criteria could identify some patients before the progression to definite CP, while the majority of the patients did not progress.
