Does pregnancy increase the risk of cholecystectomy following bariatric surgery? A cross-sectional cohort study

Risk Factors for Symptomatic Gallstone Disease and Gallstone Formation After Bariatric Surgery

PURPOSE

Patients who undergo bariatric surgery are at risk for developing cholesterol gallstones. We aimed to identify risk factors that are associated with symptomatic gallstone disease and gallstone formation after bariatric surgery.

MATERIALS AND METHODS

We included participants of the UPGRADE trial, a multicenter randomized placebo-controlled trial on the prevention of symptomatic gallstone disease with ursodeoxycholic acid (UDCA) after bariatric surgery. The association between patient characteristics and symptomatic gallstone disease, and gallstone formation was evaluated using logistic regression analysis.

RESULTS

Of 959 patients, 78 (8%) developed symptomatic gallstone disease within 24 months. Risk factors were the presence of a pain syndrome (OR 2.07; 95% CI 1.03 to 4.17) and asymptomatic gallstones before surgery (OR 3.15; 95% CI 1.87 to 5.33). Advanced age (OR 0.95; 95% CI 0.93 to 0.97) was protective, and UDCA prophylaxis did not reach statistical significance (OR 0.64; 95% CI 0.39 to 1.03). No risk factors were identified for gallstone formation, whereas advanced age (OR 0.98; 95% CI 0.96 to 1.00), statin use (OR 0.42; 95% CI 0.20 to 0.90), and UDCA prophylaxis (OR 0.47; 95% CI 0.30 to 0.73) all reduced the risk.

CONCLUSION

Young patients with a preoperative pain syndrome and/or asymptomatic gallstones before bariatric surgery are at increased risk for symptomatic gallstone disease after surgery. Whether statins, either alone or in combination with UDCA prophylaxis, can further reduce the burden of gallstones after bariatric surgery should be investigated prospectively.

Care of Pregnant Women With a History of Bariatric Surgery

In recent years, the incidence of bariatric surgery has increased among women of reproductive age. Health care providers should be knowledgeable about the impact bariatric surgery has on women and developing fetuses to effectively provide care from preconception through postpartum. Although pregnancy in women with normal weight or with excess weight after bariatric surgery has better outcomes when compared to pregnancy complicated by obesity, it is associated with complications such as nutritional deficiencies, low birth weight, and fetal growth restriction. Consequently, a multidisciplinary approach is recommended to ensure adequate nutrition, counseling, and screening before and during pregnancy. This article summarizes evidence regarding pregnancy complications that may occur in women with a history of bariatric surgery and presents a nursing, advanced practice nursing, and midwifery plan of care for these women before, during, and after pregnancy.
