    Abstract Fast-track pathways for diagnosing esophageal or gastric cancer (EGC) have been implemented in several European countries. In Sweden, symptoms such as dysphagia, early satiety, and other alarm symptoms call for a referral for gastroscopy, according to the Swedish Standardized Course of Care (SCC). The aim of this study was to evaluate the diagnostic yield of the SCC criteria for EGC, to review all known EGC cases in Region Örebro County between March 2017 and February 2021, and to compare referral indication(s), waiting times, and tumor stage. In our material, EGC was found in 6.2% of the SCC referrals. Esophageal dysphagia had a positive predictive value (PPV) of 5.6%. The criterion with the highest PPV for EGC was suspicious radiological findings, with a PPV of 24.5%. A total of 139 EGCs were diagnosed, 99 (71%) through other pathways than via the SCC. Waiting times were approximately 14 days longer for patients evaluated via non-SCC pathways. There was no statistically significant association between referral pathway and primary tumor characteristics. The results show that a majority of the current SCC criteria are poor predictors of EGC, and some alarm symptoms lack a sufficiently specific definition, e.g., dysphagia. Referral through this fast track does not seem to have a positive impact on disease outcomes.

    Abstract Background: Fast-track pathways for diagnosing colorectal cancer (CRC) have been implemented in several European countries. In Sweden, a substantial number of CRC are diagnosed via the Swedish Standardized Course of Care for colorectal cancer (SCC-CRC). We evaluated the SCC-CRC in terms of CRC yield, and predictive values and odds ratios (OR) for the entry criteria.
    Methods: We retrospectively analyzed all 2539 patients referred for SCC-CRC colonoscopy between September 2016 and December 2020. Entry criteria and colonoscopy outcomes were analyzed.
    Results: CRC yield was 16.4%. Highest positive predictive values (PPVs) were seen for abnormal radiology (PPV 30.5%, OR 4.7 (95% CI 3.4-6.4)
    Conclusions: CRC yield from the SCC-CRC is slightly higher compared to other European fast tracks. A number of entry criteria showed no benefit towards assessing CRC risk. FIT testing should be included in CRC fast tracks to increase diagnostic efficacy.

    Abstract Adequate bowel cleansing is essential for high-quality colonoscopy. Recently, a new very low-volume 1 litre (1L) polyethylene glycol (PEG) plus ascorbate solution (ASC) has been introduced. Our aims were to assess the effectiveness and tolerability of this product compared to low-volume 2L PEG-ASC and high-volume 4L PEG solutions, in a real-life setting. In six endoscopy units in Sweden, outpatients undergoing colonoscopy were either prescribed solutions according to local routines, or the very low-volume solution in split dose regimen. Bowel cleansing effectiveness and patient experience was assessed using the Boston Bowel preparation scale (BBPS) and a patient questionnaire. A total of 1098 patients (mean age 58 years, 52% women) were included. All subsegment and the total BBPS scores were significantly greater for 1L PEG-ASC in comparison to other solutions (p < 0.05 for 1L PEG-ASC and 4L PEG for transverse and left colon, otherwise p < 0.001). Nausea was more frequent with 1L PEG-ASC compared to 2L PEG-ASC (p < 0.001) and vomiting were more often reported compared to both other solutions (p < 0.01 and p < 0.05 for 2L PEG-ASC and 4L PEG, respectively). Smell, taste, and total experience was better for 1L PEG-ASC compared to 4L PEG (p < 0.001), and similar compared to the 2L PEG-ASC. In conclusion, 1L PEG-ASC leads to better bowel cleansing compared to 2L PEG-ASC or 4L PEG products, with similar or greater patient satisfaction.

    Abstract Objectives: Primary biliary cholangitis (PBC) is an autoimmune liver disease that may progress into liver cirrhosis. Ursodeoxycholic acid (UDCA) is known to prevent or delay the disease progression, but little is known about work incapacity in PBC patients. We aimed to compare clinical outcomes (transplantation-free survival; cirrhosis development) and sick leave in patients with PBC with and without UDCA therapy.
    Methods: The medical records of 526 patients with PBC diagnosed from 2004 to 2016 were reviewed retrospectively. Sick leave data retrieved from the Swedish Social Insurance Agency were analysed for a sub-cohort of patients and matched controls. Cox regression was used for analysis of clinical outcomes. Logistic and conditional logistic regressions were used for sick leave analysis.
    Results: A total of 10.6% of patients died and 3.4% received liver transplantation over a median follow-up time of 5.7 years. UDCA-untreated patients (HR 3.62 (95%CI 2.02-6.49)) and UDCA non-responders (HR 3.78 (95% CI 1.87-7.66)) had higher mortality or transplantation rates than UDCA responders. Patients with PBC had higher odds of sick leave (OR 2.50; 95% CI 1.69-3.70) than matched controls. Untreated patients were more likely to be on sick leave (OR 3.22; 95% CI 1.12-9.25) two years after diagnosis than UDCA responders.
    Conclusion: Both untreated patients and UDCA non-responders had lower liver transplantation-free survival rates than UDCA responders. Patients with PBC were more likely to be on sick leave compared to matched controls from the general population.

    Abstract Background & aims: The evidence for hepatobiliary tumour surveillance in patients with primary sclerosing cholangitis (PSC) is scarce. In this study, we aimed to prospectively evaluate cholangiocarcinoma (CCA) surveillance with yearly MRI with cholangiopancreatography (MRI/MRCP) in a nationwide cohort.
    Methods: In total, 512 patients with PSC from 11 Swedish hospitals were recruited. The study protocol included yearly clinical follow-ups, liver function tests and contrast-enhanced MRI/MRCP and carbohydrate antigen (CA) 19-9. Patients with severe/progressive bile duct changes on MRI/MRCP were further investigated with endoscopic retrograde cholangiopancreatography. Patients were followed for 5 years or until a diagnosis of CCA, liver transplantation (LT) and/or death. Risk factors associated with CCA were analysed with Cox regression.
    Results: Eleven patients (2%) were diagnosed with CCA, and two (0.5%) with high-grade bile duct dysplasia. Severe/progressive bile duct changes on MRI/MRCP were detected in 122 patients (24%), of whom 10% had an underlying malignancy. The primary indication for LT (n = 54) was biliary dysplasia in nine patients (17%) and end-stage liver disease in 45 patients (83%), of whom three patients (7%) had unexpected malignancy in the explants. The median survival for patients with CCA was 13 months (3-22 months). Time to diagnosis of high-grade dysplasia and/or hepatobiliary malignancy was significantly associated with severe/progressive bile duct changes on MRI/MRCP (hazard ratio 10.50; 95% CI 2.49-44.31) and increased levels of CA19-9 (hazard ratio 1.00; 95% CI 1.00-1.01).
    Conclusion: In an unselected cohort of patients with PSC, yearly CA19-9 and MRI/MRCP surveillance followed by ERCP was ineffective in detecting cancer early enough to support long-term survival. Given the low occurrence of CCA, studies on individualised strategies for follow-up and improved diagnostic methods for PSC-related CCA are warranted.
    Impact and implications: A prospective nationwide 5-year study was conducted to evaluate yearly cholangiocarcinoma surveillance using MRI and CA19-9 in patients with primary sclerosing cholangitis. Only 2% of the patients were diagnosed with cholangiocarcinoma during follow-up and their prognosis remained poor despite surveillance. This surveillance strategy failed to detect cancer early enough to support long-term survival. Therefore, individualised strategies and improved diagnostic methods will be required to improve the early detection of cholangiocarcinoma in patients with primary sclerosing cholangitis.

    Abstract Background: Data on rescue treatment of autoimmune hepatitis in patients that fail standard treatment are sparse.
    Aims: To report our long-term experience with mycophenolate mofetil.
    Methods: Retrospective study in 22 patients with autoimmune hepatitis who failed azathioprine and prednisolone due to adverse events (n = 14, 64%), lack of remission (n = 5, 23%) or a combination (n = 3, 13%).
    Results: Mycophenolate mofetil was started at a dose of 20 mg/kg/day and increased to a maximum of 3 g/day. Follow-up was 0-6 months in 7 patients; more than 12 months in 15 (68%) and more than 24 months in 10. Normal aminotransferase levels were obtained (n = 3) or maintained (n = 7) in 10 patients (45%) after three to 30 weeks. 12 patients (55%) were withdrawn during the first 6 months, due to adverse events. Three patients were switched to cyclosporine and one underwent liver transplantation. Successful treatment with mycophenolate mofetil continued in 10 patients (45%) for a median of 71 months (range 20-124). Of these, one stopped prednisolone, five have a prednisolone dose <5 mg daily and four patients 5-10 mg.
    Conclusion: Approximately one of two patients with autoimmune hepatitis that fail standard treatment benefit from long-term maintenance with mycophenolate mofetil, especially those with previous intolerance to thiopurines, where mycophenolate mofetil is effective in two thirds.

    Abstract Background/aims: An effective workflow at the endoscopy unit is important for optimal production. We conducted a time-and-motion study to identify the amount of time that patients spend during the different steps of a regular endoscopy procedure and compared propofol with midazolam sedation.
    Methods: Data from 376 patients were prospectively collected. Durations of the different procedure steps were measured. Correlations between recovery times, age, and dose of sedative were calculated. Multiple regression analysis was performed to evaluate how various factors affect recovery time.
    Results: The use of midazolam resulted in significantly shorter procedure duration for gastroscopy (5.1 vs 8.3 min), shorter endoscopist delay duration for either types of endoscopy (5.9 vs 8.3 min for gastroscopy and 6.7 vs 11.4 min for colonoscopy), shorter endoscopy room duration for gastroscopy (22.2 vs 30.0 min), shorter recovery time for colonoscopy (23.4 vs 27.4 min) and shorter Endoscopy Unit Duration for either type of endoscopy (77.1 vs 101.4 min for gastroscopy and 99.6 vs 123.2 min for colonoscopy). There was a weak correlation between dose of midazolam and recovery time.
    Conclusions: In contrast to other studies, propofol administration leads to more time spent at different steps in the workflow at our unit. Implementing propofol sedation will not improve efficacy if other steps in the workflow are not taken into account.
