RESUMEN
INTRODUCTION: Smoking cessation, both pre- and postoperatively, is important to reduce complications associated with surgery. Identifying feasible and effective means of alerting the patient before surgery to the importance of perioperative smoking cessation is a challenge to healthcare systems. MATERIAL AND METHODS: A randomized registry-based trial using the web-version of the Swedish national quality register for gynecological surgery, GynOp, was performed (ClinicalTrials.gov NCT03942146). Current smokers scheduled for gynecological surgery were randomly assigned before surgery to group 1 (control group, no specific information), group 2 (web-based written information), group 3 (information to doctor that the woman was a smoker and should be recommended smoking cessation or group 4 (a combination of groups 2 and 3). Perioperative smoking habits were evaluated in a postoperative questionnaire 2 months after surgery. The treatment effect was estimated to be a 15% reduction in the number of smokers at the time of surgery. Thus, 94 women in each group were required, in total 376 women, using a one-sided test with an alpha level of 0.001 and a statistical power of 80%. RESULTS: Participants (n = 1427) were recruited between 5 November 2015 and 6 December 2017. A total of 1137 smokers responded to the follow-up questionnaire (80%), with 486 women declining to participate, leaving 651 women eligible for analysis. Women who received both web-based information prior to surgery and information from a doctor, reported smoking cessation more often from 1 to 3 weeks preoperatively (Odds ratio [OR] 1.8, 95% confidence interval [CI] 1.0-3.3) and 1 to 3 weeks after surgery (OR 1.9, 95% CI 1.1-3.3) compared with the control group who received no specific information. CONCLUSIONS: A combination of written information in the health declaration and a recommendation from a doctor regarding smoking cessation may be associated with higher odds of smoking cessation at 1-3 weeks pre- and postoperatively.

INTRODUCTION: The aim of this study was to study the impact of body mass index (BMI) and smoking on the outcome of hysterectomy and whether effects of these factors vary between abdominal, laparoscopic and vaginal hysterectomy. MATERIAL AND METHODS: Pre-, per- and postoperative (8 weeks) data were retrieved from the Swedish National Register for Gynecological Surgery on 28 537 hysterectomies performed because of a benign indication between 2004 and 2013. Multivariable logistic regression analyses were used to identify independent factors affecting the rate of complications, presented as adjusted odds ratios (adjOR) with 95% confidence intervals (CI). RESULTS: Overweight and obesity had the strongest impact on complications in the abdominal hysterectomy group. In women with a BMI ≥ 30 an increased adjOR could be seen for bleeding >1000 mL (2.90; 95% CI 2.23-3.77), peroperative complications (1.54; 95% CI 1.26-1.88), operation time >120 min (2.67; 95% CI 2.33-3.03), postoperative complications (1.21; 95% CI 1.08-1.34) and postoperative infections (1.73; 95% CI 1.50-1.99). With vaginal hysterectomy, the effect of BMI ≥ 30 could be seen in relation to excessive bleeding >500 mL (1.63; 95% CI 1.22-2.17) and operative time >120 min (2.00; 95% CI 1.60-2.50). With laparoscopic hysterectomy (LH), a BMI ≥ 30 had a higher adjOR for prolonged surgery (1.71; 95% CI 1.30-2.26). Smokers had an increased risk of postoperative infection in the abdominal hysterectomy (1.23; 95% CI 1.07-1.40) and vaginal hysterectomy groups (1.21; 95% CI 1.02-1.43) but not in the LH group. CONCLUSIONS: Body mass index and smoking had a negative effect with all hysterectomy approaches but to a lesser extent in vaginal and laparoscopic hysterectomies. This should be taken into consideration in advance of surgery to improve outcome.
