Abstract 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.

Background and study aims In contrast with the European Society of Gastrointestinal Endoscopy (ESGE) 2013 and the US Multi-society Task Force (USMSTF) 2020 guidelines, the ESGE 2020 guideline considers patients with three to four adenomas

ABSTRACT Background and aims: to assess the usefulness, efficacy and safety of single-operator cholangiopancreatoscopy (SOCP) with the SpyGlass(tm) system for the management of biliopancreatic diseases. Methods: a retrospective analysis of patients undergoing SOCP with the SpyGlass(tm) between September 2008 and April 2016 was performed. Data was obtained from a prospectively-maintained database at a tertiary referral center. The primary study outcomes were technical and complete endoscopic success of the procedure. Two different SpyGlass(tm) systems were employed; the former is called legacy and the latter, digital system (DS). Results: a total of 107 SOCP procedures in 93 patients performed by a single operator were analyzed. Technical success of the SpyGlass(tm) examination was achieved in 90/93 (97%) of patients and complete success by resolving the biliopancreatic condition in 82/93 (88%) cases. In indeterminate biliary strictures, a complete success was achieved in 45/52 (85%) of cases. With regard to stone treatment, technical success was achieved in 34/34 (100%) patients and complete success, in 31/34 (91%) cases. Electrohydraulic lithotripsy was applied in 16/34 (47%) of cases. There were a total of 7/93 adverse effects (7.5%). Conclusions: SOCP is a useful and safe technique for the treatment of biliopancreatic diseases with a low rate of adverse effects. The procedure seems technically demanding and dedication is required.

Colorectal cancer (CRC) is the second most frequent cancer both in incidence and mortality in women, especially in those over 60 years of age. Diagnosis in women at gestational age is rare, so its incidence during pregnancy is low. However, an increase in its diagnosis is expected during the next years because of the raise in the average age of pregnancy. In most cases, the diagnosis is delayed because symptoms related to CRC can be attributed to pregnancy itself. Up to 30 % of CRC cases may present as an intestinal obstruction. In this situation, the main objective is to solve the clinical emergency in the safest way for mother and fetus, together with performing an accurate diagnostic approach to offer the best possible therapeutic management knowing the limitations and difficulties related to pregnancy. The self-expanding metallic stent (SEMS) can be particularly useful in colon obstruction in a pregnant patient with CRC because it allows solving the acute condition providing time to perform a more accurate staging study and to prepare the patient for surgery, thus reducing both post-surgical morbidity and mortality. We report on the case of a patient who early in the second trimester of pregnancy presented with an acute colonic obstruction due to CRC which was successfully managed with the placement of a self-expanding metal stent.
