    Abstract Background/aims: Endoscopic vacuum therapy (EVT) can heal a variety of defects within the gastrointestinal (GI) tract via applying negative pressure, which reduces the defect size, aspirates the infected fluid, and promotes granulation tissue. Here we present our experience with EVT as it relates to both spontaneous and iatrogenic upper GI tract perforations, leaks, and fistulas.
    Methods: This retrospective study was conducted at four large hospital centers. All patients who underwent EVT between June 2018 and March 2021 were included. Data on multiple variables were collected, including demographics, defect size and location, number and intervals of EVT exchanges, technical success, and hospital length of stay. Student t-test and the chi-squared test were used to analyze the data.
    Results: Twenty patients underwent EVT. The most common defect cause was spontaneous esophageal perforation (50%). The most common defect location was the distal esophagus (55%). The success rate was 80%. Seven patients were treated with EVT as the primary closure method. The mean number of exchanges was five with a mean interval of 4.3 days between exchanges. The mean length of hospital stay was 55.8 days.
    Conclusion: EVT is a safe and effective initial management option for esophageal leaks and perforations.

    Abstract Objectives: The impact of fatty pancreas on pancreatic parenchymal changes is unclear. The aim of this study is to assess parenchymal alterations over time in patients with fatty pancreas (FP).
    Methods: This is a retrospective study (2014-2021) of patients with FP identified on endoscopic ultrasound (EUS). Subjects with follow up imaging studies including Computed Tomography (CT) scan, Magnetic Resonance Imaging (MRI), and EUS at least two years after the initial EUS were included.
    Results: A total of 39 patients with a mean age of 51.21 ± 12.34 years were included. Mean initial weight was 80.17 ± 17.75 kg. Diabetes, hepatic steatosis, and EPI were present in 15%, 46% and 33% of the patients at baseline, respectively. In 25 patients with available follow up EUS over 2.4 ± 0.76 years, 16% progressed to chronic pancreatitis (CP) and 24% had progressive parenchymal changes without meeting the criteria for CP. One patient progressed from focal to diffuse FP, while one patient had resolution of FP. In multivariate analysis, progressive parenchymal changes on EUS were associated with an increase in weight over time (p-value 0.04), independent of the effects of gender, alcohol, or tobacco.
    Conclusion: Progressive parenchymal changes were noted in 44%. Our result suggests that FP is a dynamic process with the possibility of progression or regression over time.

    Abstract Background and aims: Endoscopic suturing enables full closure of large defects after endoscopic submucosal dissection (ESD). However, its use is limited by the need for a double-channel endoscope. A novel closure system, the OverStitch Sx (Apollo Endosurgery, Austin, Tex, USA), compatible with any single-channel endoscope, was introduced to address these shortcomings. The aim of this study was to assess the safety and feasibility of OverStitch Sx for the closure of large defects after ESD.
    Methods: This is a prospective single-center feasibility study of patients who underwent closure of large defects after ESD using the OverStitch Sx system. Main outcomes of the study are technical and clinical success, same-day discharge rate, and adverse event rate.
    Results: Thirty-three patients were enrolled. The mean diameter of included lesions was 5.38 ± 2.52 cm. The defect occupied ≥50% of the lumen circumference in 70% of the cases. En-bloc resection, R0 resection, and curative resection were achieved in 97%, 87.5%, and 78.8% of patients, respectively. Technical success and clinical success were seen in 93.9% and 90.9% of the cases, respectively. Same-day hospital discharge was achieved in 77.4% of patients. Total adverse event rate was 35.7%, including delayed bleeding in 1 patient after rectal ESD that was managed conservatively, self-resolving rectal pain in 7 patients, rectal stricture requiring dilation in 1 patient, and temporary dysphagia in 1 patient. No immediate or delayed perforation was reported.
    Conclusions: OverStitch Sx enabled safe and effective closure of large defects after ESD. Future trials are needed to determine its superiority over OverStitch for the closure of defects in challenging locations. (Clinical trial registration number: NCT04361227.).
