Cholecystectomy Risk in Crohn's Disease Patients After Ileal Resection: a Long-term Nationwide Cohort Study

Risk Factors for Gallstones in Crohn's Disease: A Systematic Review and Meta-Analysis

BACKGROUND

Crohn's disease (CD) have an increased risk of gallstone disease. We aimed to systematically evaluate the prevalence rate and relevant risk factors of gallstones in CD patients.

METHODS

A comprehensive search of PubMed, Embase, and Web of Science databases from inception to September 10, 2023, identified studies investigating risk factors for gallstone development among CD patients. Gender, age, body mass index, disease duration, disease site, stenosis, prior surgery, hospitalization times, corticosteroids, immunomodulators, and total parenteral nutrition (TPN) were assessed as potential risk factors. Odds ratios (OR) and confidence intervals (CI) were calculated.

RESULT

Among 1184 articles, 11 observational studies (3588 patients) were included. The prevalence of CD patients with gallstones was approximately 14.7%. Factors significantly associated with increased gallstone risk included Age ≥ 40 years old (OR 3.06, 95% CI 2.09- 4.48), disease duration > 15 years (OR 3.01, 95% CI 2.06-4.42), lifetime surgery(OR 2.50, 95% CI 1.99-3.12), disease located in ileocolon (OR 1.38, 95% CI 1.04-1.83) and ileocecal(OR 1.93, 95% CI 1.16-3.21), multiple hospitalizations(OR 4.26, 95% CI 2.43-7.46), corticosteroid treatments(OR 2.65, 95% CI 1.52-4.63), immunomodulator therapy(OR 1.94, 95% CI 1.12-3.38), and TPN use(OR 2.66, 95% CI 1.29-5.51). Sex, stenosis, overweight, or low weight did not significantly increase the risk of gallstone developing.

CONCLUSION

Age, long disease duration, specific disease locations (ileocolon, ileocecal), surgery, number of hospitalizations, corticosteroids, immunomodulator therapy, and TPN were identified as factors that increased the risk of gallstones in CD patients. About 14.7% of CD patients experience gallstones, so raising awareness and implementing prevention are needed.

Surgery and Perioperative Management in Small Intestinal Neuroendocrine Tumors

Small-intestinal neuroendocrine tumors (SI-NETs) are the most prevalent small bowel neoplasms with an increasing frequency. In the multimodal management of SI-NETs, surgery plays a key role, either in curative intent, even if R0 resection is feasible in only 20% of patients due to advanced stage at diagnosis, or palliative intent. Surgeons must be informed about the specific surgical management of SI-NETs according to their hormonal secretion, their usual dissemination at the time of diagnosis and the need for bowel-preserving surgery to avoid short bowel syndrome. The aim of this paper is to review the surgical indications and techniques, and perioperative and postoperative management of SI-NETs.
