Abstract

Background and study aims: Motorized spiral enteroscopy is proven to be effective in antegrade and retrograde enteroscopy. Nevertheless, little is known about its use in less common indications. The aim of this study was to identify new indications for the motorized spiral enteroscope.

Methods: Monocentric retrospective analysis of 115 patients who underwent enteroscopy using PSF-1 motorized spiral enteroscope between January 2020 and December 2022.

Results: A total of 115 patients underwent PSF-1 enteroscopy. 44 (38%) were antegrade procedures and 24 (21%) were retrograde procedures in patients with normal gastrointestinal anatomy with conventional enteroscopy indications. The remaining 47 (41%) patients underwent PSF-1 procedures for secondary less conventional indications: n=25 (22%) enteroscopy-assisted ERCP, n=8 (7%) endoscopy of the excluded stomach after Roux-en-Y gastric bypass, n=7 (6%) retrograde enteroscopy after previous incomplete conventional colonoscopy and n=7 (6%) antegrade panenteroscopy of the entire small bowel. In this group of secondary indications, technical success rate was significantly lower (72.5%) as compared to technical success rates in the conventional groups (98-100%, p<0.001 Chi-square). Minor adverse events occurred in 17/115 patients (15%), all treated conservatively (AGREE I and II).

Conclusion: This study demonstrates the capabilities of PSF-1 motorized spiral enteroscope for secondary indications. PSF-1 is useful to complete colonoscopy in case of long redundant colon, to reach the excluded stomach after Roux-en-Y gastric bypass, to perform unidirectional pan-enteroscopy and to perform ERCP in patients with surgically altered anatomy. However, technical success rates are lower as compared to conventional antegrade and retrograde enteroscopy procedures, with only minor adverse events.

电动螺旋肠镜检查:用于新适应症的有效性。

背景与研究目的:电动螺旋肠镜在顺行和逆行肠镜检查中是有效的。然而，人们对其在不常见适应症中的应用知之甚少。本研究的目的是确定电动螺旋肠镜的新适应症。方法:对2020年1月至2022年12月期间使用PSF-1电动螺旋肠镜进行肠镜检查的115例患者进行单中心回顾性分析。结果:115例患者行PSF-1肠镜检查。44例(38%)为顺行手术，24例(21%)为逆行手术，患者胃肠道解剖正常，常规肠镜检查指征。其余47例(41%)患者接受PSF-1手术治疗继发的非常规适应症:25例(22%)采用肠镜辅助ERCP, 8例(7%)采用Roux-en-Y胃旁路术后排除胃内窥镜检查，7例(6%)采用不完全常规结肠镜检查后逆行肠镜检查，7例(6%)采用整个小肠顺行全肠镜检查。在这组次要适应症中，技术成功率(72.5%)明显低于常规组的技术成功率(98-100%)。结论:本研究证明了PSF-1电动螺旋肠镜在次要适应症中的能力。PSF-1在长结肠冗余情况下完成结肠镜检查，Roux-en-Y胃旁路手术后到达被排除的胃，单向泛肠镜检查和手术改变解剖结构的患者进行ERCP时都是有用的。然而，与传统的顺行和逆行肠镜检查相比，技术成功率较低，只有轻微的不良事件。

期刊介绍： The Journal Acta Gastro-Enterologica Belgica principally publishes peer-reviewed original manuscripts, reviews, letters to editors, book reviews and guidelines in the field of clinical Gastroenterology and Hepatology, including digestive oncology, digestive pathology, as well as nutrition. Pure animal or in vitro work will not be considered for publication in the Journal. Translational research papers (including sections of animal or in vitro work) are considered by the Journal if they have a clear relationship to or relevance for clinical hepato-gastroenterology (screening, disease mechanisms and/or new therapies). Case reports and clinical images will be accepted if they represent an important contribution to the description, the pathogenesis or the treatment of a specific gastroenterology or liver problem. The language of the Journal is English. Papers from any country will be considered for publication. Manuscripts submitted to the Journal should not have been published previously (in English or any other language), nor should they be under consideration for publication elsewhere. Unsolicited papers are peer-reviewed before it is decided whether they should be accepted, rejected, or returned for revision. Manuscripts that do not meet the presentation criteria (as indicated below) will be returned to the authors. Papers that go too far beyond the scope of the journal will be also returned to the authors by the editorial board generally within 2 weeks. The Journal reserves the right to edit the language of papers accepted for publication for clarity and correctness, and to make formal changes to ensure compliance with AGEB’s style. Authors have the opportunity to review such changes in the proofs.
