In the September 2020 issue (272:449-456) of Annals of Surgery, the article by Rios-Diaz et al., “Is It Safe to Manage Acute Cholecystitis Nonoperatively During Pregnancy? A Nationwide Analysis of Morbidity According to Management Strategy,” did not include the corrections requested by the corresponding author during the production process. The online version of the article has been updated to include all of the necessary changes, and we have provided a list of the important text corrections and revised versions of Figure 1 and the tables for the article below. Please note that updates were also made to the References in the article, and we refer readers to the updated online version of the article. The Publisher apologizes for these errors.
Page 449, paragraph 1 in abstract should read: “Objectives: To compare cholecystectomy (CCY) and nonoperative treatment (no-CCY) for acute cholecystitis in pregnancy.”
Page 449, paragraph 3 in abstract, lines 2-3 should read: “Propensity-score adjusted logistic regression models were used to compare CCY and no-CCY.”
Page 449, paragraph 4 in abstract, lines 2–3 should read: “Patients were more likely to be managed operatively in their second trimester (First 43.9%, Second 59.1%, Third 34.2%; P < 0.01).”
Page 450, first paragraph under heading “Outcome Measures,” lines 2–5 should read: “Complications were defined as stillbirth/intrauterine death, poor fetal growth, abortion, preterm delivery, C-section, obstetric bleeding, venous thromboembolism (deep venous thrombosis, obstetric and nonobstetric pulmonary embolism), and infection of the amniotic cavity.”
Page 450, first paragraph under heading “Outcome Measures,” lines 5–15 should read: “The secondary outcomes were in-hospital maternal mortality, neurological (stroke), cardiac (myocardial infarction, shock, heart failure, dysrhythmia), pulmonary (respiratory failure, pneumonia, aspiration pneumonitis), genitourinary complications (acute renal failure, urinary tract infection), blood transfusion, nonroutine discharge disposition (other than home under self-care), 30-day readmission (any type, unplanned [nonelective], planned [elective]), maternal-fetal composite upon 30-day readmission, index admission hospital LOS, and cumulative LOS.”
Page 450, first paragraph under heading “Outcome Measures,” lines 23–24 should read: “For the nonoperative group, the rate of cholecystectomy upon readmission (open and laparoscopic) was reported.”
Page 451, first paragraph, lines 9–14 should read: “The predicted mean differences in LOS with 95% CI for patients who were readmitted within 30 days were obtained through risk-adjusted generalized linear models with log link and Poisson distribution (determined by modified Park tests24) followed by post-estimation calculations of average marginal effects.”
Page 451, first paragraph under “Sensitivity Analyses,” lines 3–5 should read: “Another sensitivity analysis was performed only considering maternal-fetal complications when listed as other than primary and/or secondary diagnoses.”
