Background/Aims: Device-assisted enteroscopy has advanced small bowel disorder management. We conducted this meta-analysis to compare the clinical and procedural outcomes between spiral enteroscopy and single-balloon enteroscopy. Methods: A systematic search was performed on December 1, 2024, in the PubMed, Scopus, and Cochrane Library databases to identify studies that compared spiral enteroscopy and single-balloon enteroscopy. The outcomes included diagnostic and therapeutic yields, total procedure time, depth of maximum insertion, and adverse event rates. Results: Five studies (including 496 patients) met the inclusion criteria. The diagnostic yield was similar between spiral enteroscopy and single-balloon enteroscopy (risk ratio [RR], 1.07; 95% confidence interval [CI], 0.96–1.20; p=0.24). The therapeutic yield also showed no significant difference (RR, 1.10; 95% CI, 0.45–2.69; p=0.83). The total procedure time was comparable (mean difference, –22.85 minutes; 95% CI, –46.83 to 1.12; p=0.06), although motorized spiral enteroscopy reduced the procedure time (p<0.001). Spiral enteroscopy achieved greater depth of maximum insertion (standardized mean difference, 1.33; 95% CI, 0.65–2.01; p<0.001). Adverse event rates were comparable (RR, 1.72; 95% CI, 0.80–3.70; p=0.16). Conclusions Spiral and single-balloon enteroscopies demonstrated similar diagnostic and therapeutic yields and safety. Spiral enteroscopy achieved a greater insertion depth, and motorized systems improved the efficiency in terms of procedure times.

Background/Aims: The pancreatic pseudocyst (PP) is a type of fluid collection that typically develops as a delayed complication of acute pancreatitis. Drainage is indicated for symptomatic patients and/or associated complications, such as infection and bleeding. Drainage modalities include percutaneous, endoscopic, laparoscopic, and open drainage. This study aimed to assess trends in the utilization of different drainage modalities for treating PP from 2016 to 2020. The trends in mortality, mean length of hospital stay, and mean hospitalization costs were also assessed. Methods: The National Inpatient Sample database was used to obtain data. The variables were generated using International Classification of Diseases-10 diagnostic and procedural codes. Results: Endoscopic drainage was the most commonly used drainage modality in 2018–2020, with an increasing trend over time (385 procedures in 2018 to 515 in 2020; p=0.003). This is associated with a decrease in the use of other drainage modalities. A decrease in the hospitalization cost for PP requiring drainage was also noted (29,318 United States dollar [USD] in 2016 to 18,087 USD in 2020, p<0.001). Conclusions Endoscopic drainage is becoming the most commonly used modality for the treatment of PP in hospitals located in the US. This new trend is associated with decreasing hospitalization costs.
