Background Motorized Spiral Enteroscopy (MSE) reduces procedure time and increases insertion depth into the small bowel; however, there is scarce evidence on factors afecting MSE efcacy.   Aims To evaluate diagnostic yield and adverse events of MSE including patients with prior major abdominal surgery.  Methods A prospective observational study was conducted on patients undergoing MSE from June 2019 to December 2021.  Demographic characteristics, procedure time, depth of maximum insertion (DMI), technical success, diagnostic yield, and adverse events were collected.  Results Seventy-four anterograde (54.4%) and 62 retrograde (45.6%) enteroscopies were performed in 117 patients (64 males, median age 67 years). Fifty patients (42.7%) had prior major abdominal surgery. Technical success was 91.9% for  anterograde and 90.3% for retrograde route. Diagnostic yield was 71.6% and 61.3%, respectively. The median DMI was 415 cm (264–585) for anterograde and 120 cm (37–225) for retrograde enteroscopy. In patients with prior major abdominal  surgery, MSE showed signifcantly longer small bowel insertion time (38 vs 29 min, p=0.004), with similar diagnostic yield (61 vs 71.4%, p=0.201) and DMI (315 vs 204 cm, p=0.226). The overall adverse event rate was 10.3% (SAE 1.5%), with no  diferences related to prior abdominal surgery (p=0.598). Patients with prior surgeries directly involving the gastrointestinal tract showed lower DMI (189 vs 374 cm, p=0.019) with equal exploration time (37.5 vs 38 min, p=0.642) compared to  those with other abdominal surgeries.  Conclusions MSE is efective and safe in patients with major abdominal surgery, although longer procedure times were  observed. A lower depth of insertion was detected in patients with gastrointestinal surgery.
