Direct percutaneous endoscopic jejunostomy in pediatric age with a pexies triangulation system: report of a case and literature review.

Direct percutaneous endoscopic jejunostomy (DPEJ) is an infrequent procedure as it is not always easy to obtain transillumination, being this the main reason for failure of this technique. In patients with previous surgery, this procedure is more complex and there are only 6 reported cases in pediatric population. In our case, we provide the use of an endoscopic triangulation system with "T" pexies not used before in these cases. With this technique, we guarantee not to replace the introduction system afterwards, obtaining the placement of a balloon fixation system initially. We also provide several improvements that helped us developing the procedure: Placement of the jejunostomy through a gastrostomy; use of water column to avoid penetration in hollow viscus; use of a guide wire, and a triangulation pexy system.

Prospective multicenter study to identify optimal target population for motorized spiral enteroscopy.

Motorized spiral enteroscopy (MSE) enhances small bowel exploration, but the optimal target population for this technique is unknown. We aimed to identify the target population for MSE by evaluating its efficacy and safety, as well as detecting predictors of efficacy. A prospective multicenter observational study was conducted at 9 tertiary hospitals in Spain, enrolling patients between June 2020-2022. Analyzed data included demographics, indications for the procedure, exploration time, depth of maximum insertion (DMI), technical success, diagnostic yield, interventional yield, and adverse events (AE) up to 14 days from enteroscopy. Patients with prior gastrointestinal surgery, unsuccessful balloon enteroscopy and small bowel strictures were analyzed. A total of 326 enteroscopies (66.6% oral route) were performed in 294 patients (55.1% males, 65 years ± 21). Prior abdominal surgery was present in 50% of procedures (13.5% gastrointestinal surgery). Lower DMI (162 vs 275 cm, p = 0.037) and diagnostic yield (47.7 vs 67.5%, p = 0.016) were observed in patients with prior gastrointestinal surgery. MSE showed 92.2% technical success and 56.9% diagnostic yield after unsuccessful balloon enteroscopy (n = 51). In suspected small bowel strictures (n = 49), the finding was confirmed in 23 procedures (46.9%). The total AE rate was 10.7% (1.8% classified as major events) with no differences related to prior gastrointestinal/abdominal surgery, unsuccessful enteroscopy, or suspected small bowel strictures. The study demonstrates that MSE has a lower diagnostic yield and DMI in patients with prior gastrointestinal surgery but is feasible after unsuccessful balloon-enteroscopy and in suspected small bowel strictures without safety concerns.
