Bariatric Surgery and Hepatocellular Carcinoma: a Propensity Score-Matched Analysis.

ABSTRACT: BACKGROUND:The association between obesity and rising incidence of hepatocellular carcinoma (HCC) in the USA has been documented; however, the role of bariatric surgery remains less clear. AIM:To evaluate the cross-sectional association of prior-bariatric surgery and HCC. METHODS:The United States Nationwide Inpatient Sample (NIS) database was queried from 2004 to 2014 for discharges with a diagnosis of morbid obesity. Primary outcomes of interest were HCC and in-hospital mortality rate. Secondary outcomes were length of stay and cost. Baseline characteristics were balanced using propensity score matching (PSM). Using Poisson and logistic regressions, adjusted HCC prevalence ratio (PR) and mortality odds ratio (OR) were derived in patients with prior-bariatric surgery compared to those without bariatric surgery. RESULTS:Of the 2,881,414 patients included in our study, 267,082 (9.3%) underwent bariatric surgery. From 2004 to 2014, there was a threefold increase in age-adjusted prevalence of HCC from 27 per 100,000 to 72 per 100,000 (PTrend < 0.001). After PSM, 230,956 patients with prior-bariatric surgery were matched with 230,956 patients without bariatric surgery. Prior-bariatric surgery was associated with lower prevalence of HCC (PR 0.11; 95% CI, 0.03-0.48; P?

Project description:Background: Studies have suggested that patients with prior gastric bypass may be at increased risk for hypocalcemia following thyroidectomy. Unfortunately, most of these studies are limited to case reports and small series. This study represents the largest sample size to date to assess the incidence of post-thyroidectomy hypocalcemia in patients with a history of bariatric surgery. Methods: The TriNetX Research Network was queried to retrospectively identify patients with prior bariatric surgery who underwent total thyroidectomy between 2011 and 2021. The incidence of hypocalcemia following surgery was compared with patients who underwent total thyroidectomy, and hemithyroidectomy with no history of bariatric surgery. Results: We identified 446 patients with a history of bariatric surgery and subsequent thyroidectomy, 29,346 patients with total thyroidectomy, and 19,603 patients with hemithyroidectomy alone. The one-month incidence of hypocalcemia was 54.7% in those with a history of bariatric surgery who underwent thyroidectomy, 43.9% in those with thyroidectomy alone (relative risk, RR = 1.2 [confidence interval, CI 1.1-1.4], p < 0.001), and 8.1% in those with hemithyroidectomy only (RR = 6.8 [CI 6.1-7.4], p < 0.001). Permanent hypocalcemia was documented in 11.4% of patients with prior bariatric surgery who underwent thyroidectomy, 7.7% of those with thyroidectomy only (RR = 1.5 [CI 1.1-1.9], p = 0.003), and 2.9% of patients with hemithyroidectomy alone (RR = 3.9 [CI 3.0-5.2], p < 0.001). Significant differences persisted after matching demographics, prior need for supplementation, and risk factors for hypocalcemia after thyroidectomy. When stratified by bariatric procedure, patients with a history of Roux-en-Y gastric bypass (RYGB) (n = 35) had a greater, although not statistically significant, risk of short-term hypocalcemia (51.4%; RR = 1.2 [CI 0.8-1.6], p = 0.37), and a significantly increased risk of permanent hypocalcemia (20.0%; RR = 2.6 [CI 1.3-5.1], p = 0.005) compared with thyroidectomy alone. Sleeve gastrectomy (SG) (n = 40) was not associated with an increased risk of short-term (40.0%; RR = 0.9 [CI 0.6-1.3], p = 0.62) or permanent (7.5%; RR = 1.0 [CI 0.3-2.9], p = 0.96) hypocalcemia. Conclusions: Prior RYGB, but not SG, may increase the risk of permanent hypocalcemia after thyroidectomy. Additional research is necessary to determine optimal prevention and treatment strategies to reduce morbidity in this population.
