RESUMO
BACKGROUND: The ideal treatment of epithelial neoplastic rectal lesions involving the dentate line is a controversial issue. Piecemeal endoscopic mucosal resection (EMR) is the most commonly used resection technique, but it is associated with high recurrence rates. Endoscopic submucosal dissection (ESD) has been shown to be safe and effective for the treatment of rectal lesions, but evidence is lacking concerning its application close to the dentate line. The aim of our study is to compare ESD and EMR for the treatment of epithelial rectal lesions involving the dentate line. METHODS: We identified all cases of endoscopic resections of rectal lesions involving the dentate line performed in two German high-volume centers between 2010 and 2022. Periinterventional and follow-up data were collected and retrospectively analyzed. RESULTS: We identified 68 ESDs and 62 EMRs meeting our inclusion criteria. ESD showed a significant advantage in en bloc resection rates (89.7% vs. 9.7%; P = 0.001) and complete resection rates (72.1% vs. 9.7%; P = 0.001). The overall curative resection rate was similar between both groups (ESD: 92.6%, EMR: 83.9%; P = 0.324), whereas in the subgroup of low-risk adenocarcinomas ESD was curative in 100% of the cases vs. 14% in the EMR group (P = 0.002). There was one local recurrence after ESD (1,5%) vs. 16 (25.8%) after EMR (P < 0.0001), and the EMR patients required an average of three further interventions. CONCLUSION: ESD is superior to EMR for the treatment of epithelial rectal lesions involving the dentate line and should be considered the treatment of choice.

BACKGROUND: Collection of bile aspirate during endoscopic retrograde cholangiopancreatography (ERCP) is essential to identify pathogens responsible for acute cholangitis. Limited data are available on the risk factors for the presence of multidrug-resistant organisms (MDRO) in bile. METHODS: We conducted this retrospective, single-center study to assess the prevalence and susceptibility rates of bacteria in bile cultures, and the risk factors for the presence of pathogens, MDRO, and fungi in bile. All consecutive patients who underwent biliary drainage for acute cholangitis from January 2017 to December 2019 were included. RESULTS: 443/1610 ERCPs were performed for acute cholangitis. Bile culture was collected in 91.4% (405/443), of which 86.7% were positive. Most common isolates were Enterococcus faecalis (37.6%) and Escherichia coli (32.8%). Vancomycin resistance was found in 9.9% of Enterococcus species (spp.); extended-spectrum beta-lactamases (ESBL) and carbapenemases in 11.2% and 0.9% of Enterobacteriaceae, respectively. The empiric antimicrobial therapy was changed in 26.4% (n = 107) of cases, with a clinical response in 90.7%. In multivariate analysis, biliary stenting was an independent risk factor for positive bile culture (odds ratio [OR] 9.43; P < 0.01). Independent risk factors for MDRO in bile were patient age>60 years (OR 2.51; P = 0.03), previous sphincterotomy (OR 2.57; P = 0.02), and biliary stenting (OR 2.80; P < 0.01). Previous sphincterotomy was the only risk factor for isolation of fungi in bile (OR 1.61; P = 0.04). CONCLUSIONS: Our study showed an increasing prevalence of Enterococcus spp. and MDRO. Bile cultures should be routinely collected in cholangitis and in patients with repeated ERCPs to allow more efficient antimicrobial treatment.

An aorto-esophageal fistula (AEF) is a rare and life-threatening situation, associated with aneurysms, foreign bodies, infiltrating tumors, and radiotherapy. The ideal management is unclear. Open surgery of AEF has a high mortality and morbidity. Thoracic endovascular aortic repair (TEVAR) of an AEF is an effective and safe emergency treatment for these patients. We describe a case of AEF due to esophageal cancer successfully treated the first time by total percutaneous TEVAR (pTEVAR). A 70-year-old male patient presented with massive hematemesis at the emergency department. The patient had a known history of esophageal cancer previously treated by radiochemotherapy which was completed 3 days before. Emergency upper gastrointestinal endoscopy failed to stop the bleeding. Subsequent contrast-enhanced computed tomography revealed an aorto-esophageal fistula and emergency pTEVAR was performed. The bleeding stopped directly after stent graft placement and the patient was discharged after 10 days later. He died 3 months after pTEVAR from cancer progression. pTEVAR is an effective and safe treatment option for AEF. It can be applied as a first-line treatment and offers the potential to improve survival in the emergency setting.
RESUMO
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.
RESUMO
OBJECTIVE: Acute non-variceal upper gastrointestinal bleeding (NVUGIB) is managed by standard endoscopic combination therapy, but a few cases remain difficult and carry a high risk of persistent or recurrent bleeding. The aim of our study was to compare first-line over-the-scope-clips (OTSC) therapy with standard endoscopic treatment in these selected patients. DESIGN: We conducted a prospective, randomised, controlled, multicentre study (NCT03331224). Patients with endoscopic evidence of acute NVUGIB and high risk of rebleeding (defined as complete Rockall Score ≥7) were included. Primary endpoint was clinical success defined as successful endoscopic haemostasis without evidence of recurrent bleeding. RESULTS: 246 patients were screened and 100 patients were finally randomised (mean of 5 cases/centre and year; 70% male, 30% female, mean age 78 years; OTSC group n=48, standard group n=52). All but one case in the standard group were treated with conventional clips. Clinical success was 91.7% (n=44) in the OTSC group compared with 73.1% (n=38) in the ST group (p=0.019), with persistent bleeding occurring in 0 vs 6 in the OTSC versus standard group (p=0.027), all of the latter being successfully managed by rescue therapy with OTSC. Recurrent bleeding was observed in four patients (8.3%) in the OTSC group and in eight patients (15.4%) in the standard group (p=0.362). CONCLUSION: OTSC therapy appears to be superior to standard treatment with clips when used by trained physicians for selected cases of primary therapy of NVUGIB with high risk of rebleeding. Further studies are necessary with regards to patient selection to identify subgroups benefiting most from OTSC haemostasis. TRIAL REGISTRATION NUMBER: NCT03331224.

BACKGROUND: The introduction of fine needle biopsies (FNB) to clinical practice presents a changing trend towards histology in the endoscopic ultrasound-guided tissue acquisition (EUS-TA). AIM: To evaluate the clinical performance of a new FNB needle, the 22-gauge (22G) Franseen needle, when sampling pancreatic solid lesions. METHODS: Consecutive patients with an indication for EUS-TA for the assessment of pancreatic solid lesions were included in this prospective, single-center, single-arm trial. Each patient underwent a puncture of the lesion two times using the 22G Franseen needle and the obtained samples were directly placed into formalin for histological analysis. The primary study endpoint was the rate of high-quality obtained specimen. Secondary endpoints included the length and diameter of the core specimen, the diagnostic accuracy and the complication rate. RESULTS: From June 2017 to December 2018, forty patients with pancreatic solid lesions (22 females; mean age 67.2 years) were enrolled. Tissue acquisition was achieved in all cases. High-quality histology, rated with Payne score 3, was obtained in 37/40 cases (92.5%) after two needle passes. The mean size of the acquired histological core tissue was 1.54 mm × 0.39 mm. The diagnostic accuracy for the correct diagnosis was 85% (34/40). Only one adverse event was occurred, consisting of a self-limiting bleeding in the puncture site. CONCLUSION: The 22G Franseen needle achieved according to our standardized protocol a high rate of histological core procurement, and a high diagnostic accuracy, with one minor adverse event reported.

AIM: We aimed to evaluate patients' survival and complications after percutaneous endoscopic gastrostomy (PEG) tube placement, the quality of information given to the decision-makers (relatives) before the procedure and their overall acceptance of the intervention. METHODS: We interviewed the relatives of 35 patients who underwent PEG tube placement in our facility from January 2008 to December 2009, using a structured questionnaire. RESULTS: Thirty-day survival rate was 83%. The cumulative median survival was 35 (95% CI: 27.7-42.3) days and it was not related to patient's underlying condition. No patient died due to procedure related complication. Apart from topical skin reactions (26%), major complications, such as pneumonia, diarrhea, vomiting and tube misplacement were not common (3-11%). Although 83% of the decision-makers considered that they had provided an informed decision after being given comprehensive information about the procedure, 71% said that they had not adequately been informed about alternative methods. One third of the relatives considered that the intervention met their expectations and 67% of them would recommend PEG to other patients suffering from dysphagia. However, only 26% of decision-makers would consent again for PEG tube placement for their patient, while 69% did not answer this question. CONCLUSION: Patients' outcomes after PEG tube placement are favorable. However, several decision-makers are not satisfied with the quality of information given before informed consent while the acceptance of the intervention is not very high.
