RESUMO
BACKGROUND & AIMS: Autoimmune pancreatitis (AIP) is an immune-mediated disease of the pancreas with distinct pathophysiology and manifestations. Our aims were to characterize type 1 AIP in a large pan-European cohort and study the effectiveness of current treatment regimens. METHODS: We retrospectively analyzed adults diagnosed since 2005 with type 1 or not-otherwise-specified AIP in 42 European university hospitals. Type 1 AIP was uniformly diagnosed using specific diagnostic criteria. Patients with type 2 AIP and those who had undergone pancreatic surgery were excluded. The primary end point was complete remission, defined as the absence of clinical symptoms and resolution of the index radiologic pancreatic abnormalities attributed to AIP. RESULTS: We included 735 individuals with AIP (69% male; median age, 57 years; 85% White). Steroid treatment was started in 634 patients, of whom 9 (1%) were lost to follow-up. The remaining 625 had a 79% (496/625) complete, 18% (111/625) partial, and 97% (607/625) cumulative remission rate, whereas 3% (18/625) did not achieve remission. No treatment was given in 95 patients, who had a 61% complete (58/95), 19% partial (18/95), and 80% cumulative (76/95) spontaneous remission rate. Higher (≥0.4 mg/kg/day) corticosteroid doses were no more effective than lower (<0.4 mg/kg/day) doses (odds ratio, 0.428; 95% confidence interval, 0.054-3.387) and neither was a starting dose duration >2 weeks (odds ratio, 0.908; 95% confidence interval, 0.818-1.009). Elevated IgG4 levels were independently associated with a decreased chance of complete remission (odds ratio, 0.639; 95% confidence interval, 0.427-0.955). Relapse occurred in 30% of patients. Relapses within 6 months of remission induction were independent of the steroid-tapering duration, induction treatment duration, and total cumulative dose. CONCLUSIONS: Patients with type 1 AIP and elevated IgG4 level may need closer monitoring. For remission induction, a starting dose of 0.4 mg/kg/day for 2 weeks followed by a short taper period seems effective. This study provides no evidence to support more aggressive regimens.

Serious iatrogenic bowel injuries during screening colonoscopy are rare events. If a perforation is detected during colonoscopy, endoscopic therapy can be attempted depending on the size and type as well as local endoscopic experience. We report the case of a 54-year-old female patient who was treated by endoscopic vacuum therapy (EVT) for a rectal perforation she had suffered during an outpatient screening colonoscopy. Two hours after the complication, an emergency endoscopy was performed. A perforation of the lower third of the rectum with a longitudinal diameter of 4 cm and a depth of 2.5 cm was detected. Due to the deep defect and the suspected increased risk of abscess formation after mechanical perforation closure with endoclips, we decided to perform EVT. The therapy was performed over a total period of 7 days. The patient was symptom free at all times. On the 2nd and 5th day, the endoscopic findings were re-evaluated and the inserted endosponges were changed. The sponge was adjusted to the wound conditions at each check and its length was gradually shortened. The endoscopic findings improved steadily. The EVT was completed after 7 days with the result of complete wound closure. The inflammatory parameters dropped continuously from day 1. On day 8, the patient could be discharged from inpatient treatment. No complications occurred in the post-inpatient course. This case is an example of successful EVT after iatrogenic rectal perforation. EVT should be considered for iatrogenic rectal perforation when signs of systemic inflammation are present and primary mechanical wound closure appears critical due to the depth of the defect and the presumed risk of abscess formation.
RESUMO
Background and study aims Acute esophageal perforation is a potentially life-threating condition that demands a multidisciplinary approach. Based on recently published data indicating that EVT may be effective in managing esophageal perforation, we report our institution's experience with EVT in this clinical setting. Patients and methods We retrospectively analyzed all 10 patients with acute esophageal perforation from May 2018 to January 2021, using descriptive statistics. The primary outcome was successful closure of the perforation. Secondary outcomes included the length of treatment, number of endoscopic procedures required, and complication rate. Results All patients (site of perforation: 4 upper, 2 middle, 4 lower esophagus; etiology: 8 iatrogenic, 2 foreign body ingestion) were treated with EVT successfully. In eight cases, EVT was started immediately after the perforation, in the other two cases 1 and 2 days later. The median (interquartile range) number of endoscopic procedures was 2.5 (range, 2-3) and the median duration of treatment was 7.5 days (range, 7-11.5). The sponge was placed in eight cases intraluminally, in the other two cases initially intracavitary. No complication occurred. Conclusions EVT is highly effective for managing acute esophageal perforation within 1 to 3 weeks. Immediate start of EVT to prevent abscess formation and induce defect closure is crucial.
