RESUMO
BACKGROUND: Current postpolypectomy guidelines treat 1-9 mm nonadvanced adenomas (NAAs) as carrying the same level of risk for metachronous advanced colorectal neoplasia (ACRN). AIMS: To evaluate whether small (6-9 mm) NAAs are associated with a greater risk of metachronous ACRN than diminutive (1-5 mm) NAAs. METHODS: We retrospectively evaluated 10,060 index colonoscopies performed from July 2011 to June 2019. A total of 1369 patients aged ≥ 40 years with index NAAs and having follow-up examinations were categorized into 5 groups based on size and number of index findings: Group 1, ≤ 2 diminutive NAAs (n = 655); Group 2, ≤ 2 small NAAs (n = 529); Group 3, 3-4 diminutive NAAs (n = 78); Group 4, 3-4 small NAAs (n = 65); and Group 5, 5-10 NAAs (n = 42). Size was classified based on the largest NAA. ACRN was defined as finding an advanced adenoma or colorectal cancer at follow-up. RESULTS: The absolute risk of metachronous ACRN increased from 7.2% in patients with all diminutive NAAs to 12.2% in patients with at least 1 small NAA (P = 0.002). Patients in Group 2 (adjusted odds ratio [AOR] 1.89; 95% confidence interval [CI], 1.21-2.95), Group 3 (AOR 2.40; 95% CI 1.78-4.90), Group 4 (AOR 2.77; 95% CI 1.35-5.66), and Group 5 (AOR 3.71; 95% CI 1.65-8.37) were associated with an increased risk of metachronous ACRN compared with Group 1. CONCLUSIONS: Patients with small NAAs have an increased risk of metachronous ACRN. Postpolypectomy guidelines should consider including risk stratification between small and diminutive adenomas.

GOAL: The goal of this study was to estimate the risk of renal injury after the use of 3-L polyethylene glycol (PEG) before outpatient colonoscopy. BACKGROUND: Population-based studies showed that the use of PEG was associated with renal injury, but this association has not been confirmed by prospective study. STUDY: Patients ≥40 years of age with an estimated glomerular filtration rate ≥30 mL/min were screened for enrollment. Laboratory data were collected before, during, and after the colonoscopies. Patients with a ≥30% increase in baseline serum creatinine levels were followed until a peak level was detected. Renal injury included acute renal dysfunction (ARD) and acute kidney injury (AKI), defined as a 30% to 49% increase and ≥50% increase in creatinine levels compared with the baseline, respectively. RESULTS: A total of 1163 patients (mean age, 55.7 y) completed the study. Baseline and first postcolonoscopy laboratory data were obtained an average of 17.0 days before and 17.3 days after the colonoscopies were performed, respectively. Renal injury was identified in 32 patients; 26 patients (2.2%) had ARD, and 6 patients (0.5%) had AKI. All patients with renal injury recovered fully during follow-up. In the subgroup analysis, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) before colonoscopy was statistically associated with the development of AKI (odds ratio, 6.5; 95% confidence interval, 1.2-35.5; P=0.03). CONCLUSIONS: This prospective study showed that the use of PEG was associated with a small risk of renal injury. NSAIDs use was statistically associated with AKI in the context of colonoscopy for which PEG was used for bowel preparation.

BACKGROUND AND AIMS: Polyps seen and not removed during colonoscope insertion are sometimes unable to be found during withdrawal. We aimed to evaluate whether additional inspection and polypectomy during insertion increases adenoma detection rate (ADR) compared with inspection and polypectomy entirely during withdrawal. METHODS: A total of 421 patients aged ≥ 45 years and undergoing colonoscopy were prospectively randomized to receive inspection and polypectomy during both insertion and withdrawal (study group) or inspection and polypectomy entirely during withdrawal (control group). The primary outcome was the ADR. Secondary outcomes included other adenoma-related parameters and procedure-related measures. RESULTS: Baseline demographics, procedure indications, preparation quality, total procedure time, sedative doses, colonoscopy difficulty, and patient discomfort were similar between the groups. The insertion time was significantly longer in the study group (11.1 ± 4.8 vs 6.2 ± 4.7 min, P < 0.0001). The withdrawal time was significantly longer in the control group (29.2 ± 9.8 vs 23.1 ± 7.9 min, P < 0.0001). There was no significant difference in the ADR (63.5% [study group] vs 68.1% [control group]), the mean adenoma per procedure (1.6 ± 2.0 vs 1.9 ± 2.4), or the mean adenoma per positive procedure (2.5 ± 2.0 vs 2.7 ± 2.5) between groups. The proximal colon ADR was significantly higher in the control group compared with the study group (56.2% vs 46.0%, P = 0.041). CONCLUSIONS: Additional inspection and polypectomy during colonoscope insertion did not improve ADR compared with inspection and polypectomy entirely during withdrawal. These results do not support an additional role for routine inspection during insertion (clinical trial registration number: NCT03444090).

BACKGROUND AND AIM: Same-day bidirectional endoscopy (BDE) is a commonly performed procedure, but the optimal sequence for the procedure with moderate conscious sedation is not well established. This study investigated the optimal sequence for same-day BDE under moderate conscious sedation and carbon dioxide insufflation in terms of sedation doses, patient discomfort, and colonoscopy performance. METHODS: A prospective randomized controlled study of 120 patients who were scheduled for BDE examination was performed. Colonoscopy followed by esophagogastroduodenoscopy (EGD) examination was performed in 60 patients (colonoscopy-EGD group), and EGD followed by colonoscopy examination was performed in another 60 patients (EGD-colonoscopy group). Endoscopists and patients completed a questionnaire to assess objective and subjective discomfort. RESULTS: Baseline demographics, procedure indications, bowel preparation quality, cecal intubation rate/time, colonoscopy withdrawal time, endoscopic interventions, BDE procedure time, colon polyp/adenoma detection rates, patient discomfort, and adverse events were similar between the two study groups. The total doses of fentanyl and midazolam were significantly higher for the colonoscopy-EGD group than for the EGD-colonoscopy group (83.4 ± 17.7 vs 68.7 ± 18.6 µg and 6.3 ± 1.4 vs 5.2 ± 1.3 mg, P < 0.0001 and P < 0.0001, respectively). The recovery time to discharge was significantly longer for the colonoscopy-EGD group than for the EGD-colonoscopy group (43.5 ± 16.2 vs 34.5 ± 8.9 min, P = 0.0003). CONCLUSIONS: Esophagogastroduodenoscopy followed by colonoscopy is the optimal sequence for same-day BDE under moderate conscious sedation and carbon dioxide insufflation. Following this order allows for a reduction of sedation doses and for shorter recovery times.

GOAL: To examine the residual gastric volume (RGV) in colonoscopy after bowel preparations with 3-L polyethylene glycol (PEG). BACKGROUND: Obstacles to high-volume bowel preparation by anesthesia providers resulting from concerns over aspiration risk are common during colonoscopy. STUDY: Prospective measurements of RGV were performed in patients undergoing esophagogastroduodenoscopy (EGD) and morning colonoscopy with split-dose PEG preparation, patients undergoing EGD and afternoon colonoscopy with same-day PEG preparation, and patients undergoing EGD alone under moderate conscious sedation. Colonoscopy patients were allowed to ingest clear liquids until 2 hours before the procedure. Patients undergoing EGD alone were instructed to eat/drink nothing after midnight. RESULTS: There were 860 evaluated patients, including 330 in the split-dose preparation group, 100 in the same-day preparation group, and 430 in the EGD-only group. Baseline demographics and disease/medication factors were similar. The mean RGV in patients receiving the same-day preparation (35.4 mL or 0.56 mL/kg) was significantly higher than that in patients receiving the split-dose preparation (28.5 mL or 0.45 mL/kg) and in patients undergoing EGD alone (22.8 mL or 0.36 mL/kg) (P=0.023 and P<0.0001, respectively). Within the bowel-preparation groups, patients with fasting times of 2 to 3 hours had similar RGV compared with patients who had fasting times >3 hours. The shape of the distribution and the range of RGV among the 3 study groups were similar. No aspiration occurred in any group. CONCLUSIONS: PEG bowel preparations increase RGV mildly, but seem to have no clinical significance. These results support the current fasting guidelines for colonoscopy.

BACKGROUND: To evaluate the management and outcomes of blunt pancreatic injuries based on the integrity of the major pancreatic duct (MPD). METHODS: Between August 1996 and August 2015, 35 patients with blunt pancreatic injuries underwent endoscopic retrograde pancreatography (ERP). Medical charts were retrospectively reviewed for demography, ERP timing, imaging findings, management, and outcome. RESULTS: Of the 35 patients, 21 were men and 14 were women, with ages ranging from 11 to 70 years. On the basis of the ERP findings, we propose a MPD injury classification as follows: class 1 indicates normal MPD; class 2, partial injury with intact MPD continuity; and class 3, complete injury with disrupted MPD continuity. Both classes 2 and 3 are subdivided into classes a, b, and c, which represent the pancreatic tail, body, and head, respectively. In this report, 14 cases belonged to class 1, 10 belonged to class 2, and 11 belonged to class 3. Of the 14 patients with class 1 injuries, 10 underwent nonsurgical treatment and 4 underwent pancreatic duct stenting. Of the 10 patients with class 2 injuries, 4 underwent nonsurgical treatment and 6 underwent pancreatic duct stenting. Two of the 11 patients with class 3 injuries underwent pancreatic duct stenting; one in the acute stage developed sepsis that led to death even after converting to distal pancreatectomy plus splenectomy. Of the 11 patients with class 3 injuries, spleen-preserving distal pancreatectomy was performed in 6, distal pancreatectomy plus splenectomy in 2, and Roux-en-Y pancreaticojejunostomy after central pancreatectomy in 2. The overall pancreatic-related morbidity rate was 60% and the mortality rate was 2.8%. CONCLUSION: Based on our experience, class 1 and 2 injuries could be treated by nonsurgical means and pancreatic duct stenting could be an adjunctive therapy in class 2b and 2c injuries. Operation is warranted in class 3 injuries.

BACKGROUND: A 3-l polyethylene glycol (PEG) solution provided better bowel cleansing quality than a 2-l solution for outpatient colonoscopy. Predictors of suboptimal preparation using a 3-l PEG have not been previously reported. AIMS: To investigate the possible predictors of suboptimal bowel preparation using 3-l of PEG. METHODS: We analyzed a database of 1404 consecutive colonoscopies during a 27-month period at a community hospital. A split-dose PEG regimen was provided for morning colonoscopies, and a same-day PEG regimen was provided for afternoon colonoscopies. The level of bowel cleansing was prospectively scored according to the Boston Bowel Preparation Scale (BBPS). Possible predictors of suboptimal colon preparation, defined as a BBPS score <7, were analyzed using univariate statistics and multivariate logistic regression models. RESULTS: The mean age of the study population (46.7 % men) was 52.5 years (range 20-80 years, SD 11.1 years), and the majority of patients (77.6 %) underwent morning colonoscopies. A suboptimal bowel preparation was reported in 17.2 % of the observed colonoscopies. In the multivariate regression analysis, constipation (odds ratio [OR] 1.60, 95 % confidence interval [CI] 1.15-2.22), male gender (OR 1.68, 95 % CI 1.25-2.25), obesity (OR 1.76, 95 % CI 1.29-2.41), and inadequate (<80 %) PEG consumption (OR 5.4, 95 % CI 2.67-10.89) were independent predictors of a suboptimal colon preparation. CONCLUSIONS: This prospective study identified that constipation, male gender, obesity, and inadequate intake of PEG were significant risk factors for suboptimal bowel preparation using a 3-l PEG solution for outpatient colonoscopy. Interventions of optimized colonoscopy preparation should be targeted at these patient populations.

BACKGROUND/AIMS: Two-liter polyethylene glycol (PEG) is the most commonly used bowel-cleansing regimen in Taiwan, but its efficacy is unsatisfactory. The aim of this study was to compare 2-liter and 3-liter PEG in terms of their impact on colonoscopy quality among an average-risk population. METHODS: Two-liter PEG was provided between August 2012 and May 2013, while 3-liter PEG was provided between June 2013 and March 2014. A split-dose regimen was provided for morning colonoscopy and a same-day regimen was provided for afternoon colonoscopy. The level of bowel cleansing was prospectively scored. RESULTS: A total of 407 consecutive subjects completed the 2-liter regimen, and another 407 consecutive subjects completed the 3-liter regimen. The 3-liter group had a significantly higher rate of excellent or good preparations, equivalent to a Boston bowel preparation scale of ≥7, than the 2-liter group (90 vs. 73%, p < 0.0001). More subjects in the 3-liter preparation group compared with the 2-liter group had overall adenoma (70 vs. 54%, p < 0.0001), proximal adenoma (47 vs. 35%, p = 0.0006), sessile serrated adenoma (28 vs. 6%, p < 0.0001), and advanced adenoma (21 vs. 9%, p < 0.0001). CONCLUSIONS: Three-liter PEG provided better cleansing quality and higher adenoma detection rate than 2-liter PEG.

Background: For patients with obstructive jaundice and who are indicated for pancreaticoduodenectomy (PD) or biliary intervention, either endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography and drainage (PTCD) may be indicated preoperatively. However, the possibility of procedure-related postoperative biliary tract infection (BTI) should be a concern. We tried to evaluate the impact of ERCP and PTCD on postoperative BTI. Methods: Patients diagnosed from June 2013 to March 2022 with periampullary lesions and with PD indicated were enrolled in this cohort. Patients without intraoperative bile culture and non-neoplastic lesions were excluded. Clinical information, including demographic and laboratory data, pathologic diagnosis, results of microbiologic tests, and relevant infectious outcomes, was extracted from medical records for analysis. Results: One-hundred-and-sixty-four patients from the cohort (164/689) underwent preoperative biliary intervention, either ERCP (n = 125) or PTCD (n = 39). The positive yield of intraoperative biliary culture was significantly higher in patients who underwent ERCP than in PTCD (90.4% vs. 41.0%, p < 0.001). Although there was no significance, a trend of higher postoperative BTI (13.8% vs. 2.7%) and BTI-related septic shock (5 vs. 0, 4.0% vs. 0%) in the ERCP group was noticed. While the risk factors for postoperative BTI have not been confirmed, a trend suggesting a higher incidence of BTI associated with ERCP procedures was observed, with a borderline p-value (p = 0.05, regarding ERCP biopsy). Conclusions: ERCP in patients undergoing PD increases the positive yield of intraoperative biliary culture. PTCD may be the favorable option if preoperative biliary intervention is indicated.
RESUMO
BACKGROUND/AIMS: To determine the accuracy of Rockall and Blatchford scores for predicting outcome after endoscopic treatment in two groups of patients with bleeding peptic ulcers: those who initially presented with upper gastrointestinal (UGI) bleeding (Group A) and those who developed UGI bleeding during hospital treatment for another condition (Group B). METHODOLOGY: A total of 593 patients who had had endoscopic treatment for bleeding peptic ulcers from January 2009 to July 2010 were divided into Groups A and B. Endoscopic therapy including monotherapy (thermal therapy or hemoclipping) and combination therapy was applied. The Blatchford and complete Rockall scores for the two subgroups were calculated. Predictive statistics for the use of the two scoring systems were then compared for Groups A and B. RESULTS: Thirty-day re-bleeding and mortality rates increased with increased Rockall and Blatchford scores. Rockall scores were more accurate than the Blatchford scores for predicting mortality. However, neither the Rockall nor the Blatchford score could accurately predict recurrence of bleeding. When the results in Group B and Group A subgroups were compared, the average Rockall score for Group A was lower than that for Group B (5.6 vs. 6.3, p < 0.001). CONCLUSIONS: In high-risk patients with peptic ulcer bleeding, the Rockall score can better predict 30-day mortality than can the Blatchford score; this was particularly true for Group B patients.

BACKGROUND: Whether clinical outcomes of acute cholangitis (AC) vary by etiology is unclear. AIM: To compare outcomes in AC caused by malignant biliary obstruction (MBO) and common bile duct stones (CBDS). METHODS: This retrospective study included 516 patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) due to AC caused by MBO (MBO group, n = 56) and CBDS (CBDS group, n = 460). Clinical and laboratory parameters were compared between the groups. Propensity score matching (PSM) created 55 matched pairs. Confounders used in the PSM analysis were age, sex, time to ERCP, and technical success of ERCP. The primary outcome comparison was 30-d mortality. The secondary outcome comparisons were intensive care unit (ICU) admission rate, length of hospital stay (LOHS), and 30-d readmission rate. RESULTS: Compared with the CBDS group, the MBO group had significantly lower body temperature, percentage of abnormal white blood cell counts, and serum levels of aspartate aminotransferase, alanine aminotransferase, and creatinine. Body temperature, percent abnormal white blood cell count, and serum aspartate aminotransferase levels remained significantly lower in the MBO group in the PSM analysis. Platelet count, prothrombin time/international normalized ratio, and serum levels of alkaline phosphatase and total bilirubin were significantly higher in the MBO group. The MBO group had a significantly higher percentage of severe AC (33.9% vs 22.0%, P = 0.045) and received ERCP later (median, 92.5 h vs 47.4 h, P < 0.001). However, the two differences were not found in the PSM analysis. The 30-d mortality (5.4% vs 0.7%, P = 0.019), ICU admission rates (12.5% vs 4.8%, P = 0.028), 30-d readmission rates (23.2% vs 8.0%, P < 0.001), and LOHS (median, 16.5 d vs 7.0 d, P < 0.001) were significantly higher or longer in the MBO group. However, only LOHS remained significant in the PSM analysis. Multivariate analysis revealed that time to ERCP and multiple organ dysfunction were independent factors associated with 30-d mortality. CONCLUSION: MBO patients underwent ERCP later and thus had a worse prognosis than CBDS patients. Therefore, clinicians should remain vigilant in MBO patients with clinically suspected AC, and perform ERCP for biliary drainage as soon as possible.
RESUMO
INTRODUCTION: Water-assisted colonoscopy increases left colon mucus production; however, the effect of saline on mucus production is unclear. We tested the hypothesis that saline infusion may reduce mucus production in a dose-related manner. METHODS: In a randomized trial, patients were assigned to colonoscopy with CO 2 insufflation, water exchange (WE) with warm water, 25% saline, or 50% saline. The primary outcome was the Left Colon Mucus Scale (LCMS) score (5-point scale). Blood electrolytes were measured before and after saline infusion. RESULTS: A total of 296 patients with similar baseline demographics were included. The mean LCMS score for WE with water was significantly higher than that for WE with saline and CO 2 (1.4 ± 0.8 [WE water] vs 0.7 ± 0.6 [WE 25% saline] vs 0.5 ± 0.5 [WE 50% saline] vs 0.2 ± 0.4 [CO 2 ]; overall P < 0.0001), with no significant difference between the 25% and 50% saline groups. The left colon adenoma detection rate (ADR) was highest in the 50% saline group, followed by the 25% saline and the water groups (25.0% vs 18.7% vs 13.3%), but the difference was not significant. Logistic regression showed water infusion as the only predictor of moderate mucus production (odds ratio 33.3, 95% confidence interval 7.2-153.2). No acute electrolyte abnormalities were documented indicating a safe modification. DISCUSSION: The use of 25% and 50% saline significantly inhibited mucus production and numerically increased ADR in the left colon. Evaluation of the impact of mucus inhibition by saline on ADR may refine the outcomes of WE.

Fully covered self-expandable metallic stents (FCSEMSs) are inserted in patients with unresectable pancreatic ductal adenocarcinoma (PDAC) to resolve malignant distal bile duct obstructions. Some patients receive FCSEMSs during primary endoscopic retrograde cholangiopancreatography (ERCP), and others receive FCSEMSs during a later session, after the placement of a plastic stent. We aimed to evaluate the efficacy of FCSEMSs for primary use or following plastic stent placement. A total of 159 patients with pancreatic adenocarcinoma (m:f, 102:57) who had achieved clinical success underwent ERCP with the placement of FCSEMSs for palliation of obstructive jaundice. One-hundred and three patients had received FCSEMSs in a first ERCP, and 56 had received FCSEMSs after prior plastic stenting. Twenty-two patients in the primary metal stent group and 18 in the prior plastic stent group had recurrent biliary obstruction (RBO). The RBO rates and self-expandable metal stent patency duration did not differ between the two groups. An FCSEMS longer than 6 cm was identified as a risk factor for RBO in patients with PDAC. Thus, choosing an appropriate FCSEMS length is an important factor in preventing FCSEMS dysfunction in patients with PDAC with malignant distal bile-duct obstruction.
RESUMO
BACKGROUND: Recurrent common bile duct stone after endoscopic retrograde cholangiopancreatography is an undesirable problem, even when a following cholecystectomy is carried out. Important factors are the composition and properties of stones; the most significant etiology among these is the lipid level. While numerous studies have established the association between serum lipid levels and gallstones, no study has previously reported on recurrent common bile duct stones after endoscopic sphincterotomy with following cholecystectomy. MATERIALS AND METHODS: We retrospectively collected 2016 patients underwent endoscopic sphincterotomy from 1 January 2015 to 31 December 2017 in Linkou Chang Gung Memorial Hospital. Finally, 303 patients whose serum lipid levels had been checked following a cholecystectomy after ERCP were included for analysis. We evaluated if metabolic factors including body weight, BMI, HbA1C, serum lipid profile, and lipid-lowering drugs may impact the rate of common bile duct stone recurrence. Furthermore, we tried to find if there is any factor that may impact time to recurrence. RESULTS: A serum HDL level ≥ 40 (p = 0.000, OR = 0.207, 95% CI = 0.114-0.376) is a protective factor, and a total cholesterol level ≥ 200 (p = 0.004, OR = 4.558, 95% CI = 1.625-12.787) is a risk factor of recurrent common bile duct stones after endoscopic sphincterotomy with cholecystectomy. Lipid-lowering drugs, specifically statins, have been shown to reduce the risk of recurrence significantly (p = 0.003, OR = 0.297, 95% CI = 0.132-0.665). No factors were found to impact the time to recurrence in this study. CONCLUSIONS: The serum lipid level could influence the recurrence of common bile duct stones after endoscopic sphincterotomy followed by cholecystectomy, and it appears that statins can reduce the risk of recurrence.
RESUMO
Predictors of needle-knife pre-cut papillotomy (NKP) failure for patients with difficult biliary cannulation has not been reported. Between 2004 and 2016, 390 patients with difficult biliary cannulation undergoing NKP were included in this single-center study. Following NKP, deep biliary cannulation failed in 95 patients (24.4%, NKP-failure group) and succeeded in 295 patients (75.6%, NKP-success group). Patient and technique factors were used to identify the predictors of initial NKP failure. Compared with the NKP-success group, periampullary diverticulum (28.4% vs. 18%, p = 0.028), surgically altered anatomy (13.7% vs. 7.1%, p = 0.049), number of cases performed by less experienced endoscopists, and bleeding during NKP (38.9% vs. 3.4%, p < 0.001), were significantly more frequent in the NKP-failure group. On multivariate analysis, surgically altered anatomy (OR 2.374, p = 0.045), endoscopists' experience (OR 3.593, p = 0.001), and bleeding during NKP (OR 21.18, p < 0.001) were significantly associated with initial failure of NKP. In conclusion, NKP is a highly technique-sensitive procedure, as endoscopists' experience, bleeding during NKP, and surgically altered anatomy were predictors of initial NKP failure.

BACKGROUND: The optimal timing of endoscopic retrograde cholangiopancreatography (ERCP) in acute cholangitis (AC) is uncertain, especially in patients with AC of varying severity. AIM: To report whether the timing of ERCP is associated with outcomes in AC patients with different severities. METHODS: According to the 2018 Tokyo guidelines, 683 patients who met the definite diagnostic criteria for AC were retrospectively identified. The results were first compared between patients receiving ERCP ≤ 24 h and > 24 h and then between patients receiving ERCP ≤ 48 h and > 48 h. Subgroup analyses were performed in patients with grade I, II or III AC. The primary outcome was 30-d mortality. Secondary outcomes were intensive care unit (ICU) admission rate, length of hospital stay (LOHS) and 30-d readmission rate. RESULTS: Taking 24 h as the critical value, compared with ERCP > 24 h, malignant biliary obstruction as a cause of AC was significantly less common in the ERCP ≤ 24 h group (5.2% vs 11.5%). The proportion of cardiovascular dysfunction (11.2% vs 2.6%), respiratory dysfunction (14.2% vs 5.3%), and ICU admission (11.2% vs 4%) in the ERCP ≤ 24 h group was significantly higher, while the LOHS was significantly shorter (median, 6 d vs 7 d). Stratified by the severity of AC, higher ICU admission was only observed in grade III AC and shorter LOHS was only observed in grade I and II AC. There were no significant differences in 30-d mortality between groups, either in the overall population or in patients with grade I, II or III AC. With 48 h as the critical value, compared with ERCP > 48 h, the proportion of choledocholithiasis as the cause of AC was significantly higher in the ERCP ≤ 48 h group (81.5% vs 68.3%). The ERCP ≤ 48 h group had significantly lower 30-d mortality (0 vs 1.9%) and shorter LOHS (6 d vs 8 d). Stratified by AC severity, lower 30-d mortality (0 vs 6.1%) and higher ICU admission rates (22.2% vs 10.2%) were only observed in grade III AC, and shorter LOHS was only observed in grade I and II AC. In the multivariate analysis, cardiovascular dysfunction and time to ERCP were two independent factors associated with 30-d mortality. CONCLUSION: ERCP ≤ 48 h conferred a survival benefit in patients with grade III AC. Early ERCP shortened the LOHS in patients with grade I and II AC.

Background: Concurrent acute cholecystitis and acute cholangitis is a unique clinical situation. We tried to investigate the optimal timing of cholecystectomy after adequate biliary drainage under this condition. Methods: From January 2012 to November 2017, we retrospectively screened all in-hospitalized patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) and then identified patients with concurrent acute cholecystitis and acute cholangitis from the cohort. The selected patients were stratified into two groups: one-stage intervention (OSI) group (intended laparoscopic cholecystectomy at the same hospitalization) vs. two-stage intervention (TSI) group (interval intended laparoscopic cholecystectomy). Interrogated outcomes included recurrent biliary events, length of hospitalization, and surgical outcomes. Results: There were 147 patients ultimately enrolled for analysis (OSI vs. TSI, 96 vs. 51). Regarding surgical outcomes, there was no significant difference between the OSI group and TSI group, including intraoperative blood transfusion (1.0% vs. 2.0%, p = 1.000), conversion to open procedure (3.1% vs. 7.8%, p = 0.236), postoperative complication (6.3% vs. 11.8%, p = 0.342), operation time (118.0 min vs. 125.8 min, p = 0.869), and postoperative days until discharge (3.37 days vs. 4.02 days, p = 0.643). In the RBE analysis, the OSI group presented a significantly lower incidence of overall RBE (5.2% vs. 41.2%, p < 0.001) than the TSI group. Conclusions: Patients with an initial diagnosis of concurrent acute cholecystitis and cholangitis undergoing cholecystectomy after ERCP drainage during the same hospitalization period may receive some benefit in terms of clinical outcomes.
RESUMO
BACKGROUND: Although the outcomes of caustic ingestion differ between children and adults, it is unclear whether such outcomes differ among adults as a function of their age. This retrospective study was performed to ascertain whether the clinical outcomes of caustic ingestion differ significantly between elderly and non-elderly adults. METHODS: Medical records of patients hospitalized for caustic ingestion between June 1999 and July 2009 were reviewed retrospectively. Three hundred eighty nine patients between the ages of 17 and 107 years were divided into two groups: non-elderly (< 65 years) and elderly (≥ 65 years). Mucosal damage was graded using esophagogastroduodenoscopy (EGD). Parameters examined in this study included gender, intent of ingestion, substance ingested, systemic and gastrointestinal complications, psychological and systemic comorbidities, severity of mucosal injury, and time to expiration. RESULTS: The incidence of psychological comorbidities was higher for the non-elderly group. By contrast, the incidence of systemic comorbidities, the grade of severity of mucosal damage, and the incidence of systemic complications were higher for the elderly group. The percentages of ICU admissions and deaths in the ICU were higher and the cumulative survival rate was lower for the elderly group. Elderly subjects, those with systemic complications had the greatest mortality risk due to caustic ingestion. CONCLUSIONS: Caustic ingestion by subjects ≥65 years of age is associated with poorer clinical outcomes as compared to subjects < 65 years of age; elderly subjects with systemic complications have the poorest clinical outcomes. The severity of gastrointestinal tract injury appears to have no impact on the survival of elderly subjects.

BACKGROUND/AIMS: Gastric outlet obstruction (GOO) is frequently caused by tumor. Recently, endoscopic implantation of self-expanding metallic stents (SEMS) has been introduced as an improved palliative treatment for GOO. This study aims to study the effect of SEMS placement on nutrient intake in patients with GOO and correlate different SEMS positions with postoperative clinical outcomes. METHODOLOGY: Fifty six non-operable patients with GOO were enrolled. Obstruction of the duodenum (n=23) or gastric outlet (n=33) were commonly found. Either Wallstent Enteral Stents, WallFlex Enteral Duodenal or partially covered Ultraflex esophageal stents were placed under endoscopic and fluoroscopic guidance. The Gastric Outlet Obstruction Score (GOOSS) was used as the main outcome measurement. RESULTS: The procedure was technically feasible in 100% of patients and gave satisfactory clinical results in 98.2% (55/56). The patients had a median survival time of 97.5 days (range 9-380). Median stent patency was 72 days with a range of 8 to 267 days. The average GOOSS, measuring oral intake, was significantly improved, regardless of obstruction site (p<0.05). We also found that the site of SEMS placement did not affect the clinical outcome. CONCLUSIONS: Palliation with SEMS is a safe and effective method for restoring gastric intake in patients with malignant GOO.
