Ultrasonographic diagnosis of ileo-ileal intussusception secondary to Vanek's tumor

Intussusception is a common condition of bowel obstruction in pediatric patients. However, 5% of all cases occur in adults, mostly aged over fifty, with no difference based on sex, representing about 1% of all causes of bowel obstruction. Compared to pediatric population, it is triggered by a pathologic lead point in about 85% of cases, represented in 60% of cases by malignant and benign neoplasms. Among these neoplasms, an inflammatory fibroid polyp (IFP), a benign neoplastic submucosal lesion also known as Vanek's tumor, is considered a very uncommon cause of adult intussusception. Clinical presentation could differ by location and size of tumor, and may include abdominal pain, nausea, vomiting, diarrhea or constipation, bleeding, weight loss, palpable abdominal mass, bowel obstruction, and gastrointestinal bleeding. Considering its common and non-specific symptoms, radiologic imaging plays a key role in the diagnosis of an IFP, especially computed tomography (CT) scan, which represents the most sensitive modality to confirm intussusception. However, bowel sonography (BS) has become an accurate procedure in various pathological intestinal diseases, also including intussusception. In this paper, we report a rare case of ileo-ileal intussusception secondary to Vanek's tumor diagnosed by BS.

Post-operative morbidity in Crohn's disease: what is the impact of patient-, disease- and surgery-related factors?

PURPOSE

Over 50% of patients suffering from Crohn's disease (CD) require surgery in their lifetime. Predictors/risk factors of post-operative morbidity and mortality in CD are poorly investigated. We aimed to assess the risk factors of post-operative morbidity/mortality in CD.

METHODS

We performed a retrospective cohort study in which all CD patients operated and followed up at our tertiary Inflammatory Bowel Disease Centre from 2014 to 2019 were enrolled. For each patient, we evaluated patient-dependent, disease-dependent and surgery-dependent variables. All patients underwent small bowel and/or colic resections.

RESULTS

Of the 165 operated patients, forty-two (25.5%) developed post-operative complications (major complication rate = 9.8%) including wound infection (12.1%), respiratory complications (4.8%), prolonged ileum (4.2%), anastomotic leak (3.6%), urinary infections (3%), abdominal abscess (2.4%), anastomotic bleeding (3.6%), abdominal bleeding (1.2%) and obstruction (0.6%). Two subjects (1.2%) required re-operation within 30 days, and one died. A surgery duration < 141 min was predictive of a better post-operative outcome (sensitivity 80.9%, specificity 43.1%, PPV 32.7%, NPV 86.9%). The multivariable analysis showed stricturing/fistulizing behaviour (OR 3.7, 95% CI 1.6-6.4, p = 0.02), need for total parenteral nutrition (OR 4.1, 95% CI 2.4-9.2, p = 0.01), pre-operative bowel cleansing (OR 0.6, 95% CI 0.41-0.83, p = 0.01) and surgery duration < 141 min (OR 0.2, 95% CI 0.08-0.7, p = 0.03) as the only risk factors associated with post-operative morbidities.

CONCLUSIONS

About 25% of CD patients develop post-operative complications. Several patient-related, disease-related and surgery-related factors should be considered risk factors for post-operative morbidity. The recognition of these factors, as well as a multidisciplinary approach to the pre-operative management of CD, could reduce post-operative complications.

In Silico Preliminary evaluation of Cx601 as new therapeutic approach in hospital clinical paths

 

Crohn's disease is a chronic inflammatory bowel disease characterized by transmural inflammation and fistula formation. Perianal fistulas are a common complication of Crohn's disease and are estimated to affect up to 28% of patients in the first two decades after diagnosis, particularly those with colonic disease and rectal involvement. Complex perianal fistulas in Crohn's disease are challenging to treat, severely impair patients' quality of life and cause substantial morbidity. Allogeneic, expanded, adipose-derived stem cells (Cx601) are a promising new therapeutic approach, although their high cost is often discouraging. We aimed at assessing the safety and efficacy of this treatment in patients with complex perianal fistulas in patients with Crohn's disease. Therefore, we conducted a meta-analysis in order to evaluate this new therapeutic approach before introducing it as standard of care. We examined 8 studies published in the last 10 years, 5 of which were selected for the final analysis. The primary outcome assessed was the combined fistula remission (clinical + imaging) assessed through the clinical examination and MRI, the control being the traditional medical strategies (ie, antibiotics, immunomodulators and anti-tumour necrosis factor agents). We registered a total of 128 events (lack of remission) in the control group vs 94 in the experimental one (Confidence Interval for OR of 0,12-0,31, P &lt; 0,001). Our “in silico” assessment is reliable, being the introduction of (Cx601) an innovative and effective treatment. Further insights will be provided by the INSPIRE registry, a multinational post-marketing study whose main objective is the evaluation of the real-world clinical effectiveness and safety of (Cx601) in patients affected by Crohn's disease with complex perianal fistulas for a duration of 36 months, to which our University “Federico II” is actively taking part.

Key messages

Disability reduction is an important goal in cronh therapeutic path of care. Our “in silico” assessment may support the introduction of (Cx601) an innovative and effective treatment.
