MOTORIZED SPIRAL ENTEROSCOPY IN PATIENTS WITH PRIOR ABDOMINAL SURGERY: A MULTICENTER OBERVATIONAL STUDY

Aims Motorized Spiral Enteroscopy (MSE) reduces procedure time and increases insertion depth into the small bowel, however there is scarce evidence on factors affecting MSE efficacy. This multicenter study aimed at evaluating diagnostic yield and adverse events of MSE in patients with prior abdominal surgery.

Methods Data of patients undergoing MSE were extracted from our national multicenter database of MSE. Data analyzed were demographic characteristics, indication for procedure, exploration time, depth of maximum insertion, technical success, diagnostic and interventional yield and adverse events.

Results Two-hundred thirteen enteroscopies, 139 anterograde (65.3%) and 74 retrograde (34.7%), were included, corresponding to 194 patients (111 males, mean age 64 years). Eighty-four patients (43.3%) had prior abdominal surgery. Technical success was 94.2% (131/139) for anterograde and 91.9% (68/74) for retrograde route. Diagnostic yield for anterograde and retrograde route was 78.4% and 63.5%, respectively. The median depth of maximum insertion was 362 cm (IQR 236-517 cm) for anterograde and 102 cm (IQR 33-225 cm) for retrograde enteroscopy. Total exploration rate was 12.4% (18 complete and 6 combined approach enteroscopies). Interventional yield was 71.8%. In patients with prior abdominal surgery no differences were detected as per diagnostic yield (72 vs 74.5%, p=0.672) and small bowel insertion time (37 vs 35 min, p=0.702). The overall adverse event rate was 8.9% (SAE 1.9%), with no differences related to prior abdominal surgery (p=0.762).

Conclusions MSE is effective in patients with prior abdominal surgery. In this cohort, adverse event rate was similar to previously published series.
