Smoking status predicts anastomotic leak after esophagectomy: a systematic review & meta-analysis.

BACKGROUND: Anastomotic leak after esophagectomy is a major contributor to surgery-related morbidity and mortality. The purpose of this systematic review was to evaluate if positive-smoking status is associated with the incidence of this complication. METHODS: A systematic search of MEDLINE, EMBASE, Scopus, Web of Science and Cochrane Library was performed on April 4th, 2023. Inclusion criteria comprised human participants undergoing esophagectomy, age ≥ 18, n ≥ 5, and identification of smoking status. The primary outcome was incidence of anastomotic leak. Sub-group analysis by ex- or current smoking status was performed. Meta-analysis was performed with RevMan 5.4.1 using a Mantel-Haenszel random-effects model. Publication bias was evaluated visually with funnel plots and through the Egger test. RESULTS: A total of 220 abstracts were screened, of which 69 full-text studies were assessed for eligibility, with 13 studies selected for final inclusion. This included 16,103 patients, of which 4433 were ex- or current smokers, and 9141 were never smokers. Meta-analysis revealed an increased odds of anastomotic leak in patients with a positive-smoking status (current or ex-smokers) compared to never smokers (OR 1.44, 95% CI 1.18-1.76, I2 = 44%, p < 0.001. Meta-analysis of six studies comparing active smokers alone to never smokers identified a significant increased odds of anastomotic leak (OR 1.80, 95% CI 1.25-2.59, p = 0.002, I2 = 0%). Meta-analysis of five studies comparing ex-smokers to never smokers identified a significant increased odds of anastomotic leak (OR 1.36, 95% CI 1.02-1.82, p = 0.04, I2 = 0%). The odds of anastomotic leak decreased among ex-smokers compared to active smokers. CONCLUSION: The findings of this systematic review and meta-analysis support the association between positive-smoking status and the risk of anastomotic leak after esophagectomy. Results further emphasize the importance of preoperative smoking cessation to reduce post-operative morbidity.

Race and sex diversity in Canadian academic surgical societies.

BACKGROUND: It is vital for national professional surgical societies to embrace diversity, inclusion, and equity. This study examines race and sex diversity in two Canadian surgical societies. METHODS: Websites of the Canadian Society of Cardiac Surgeons (CSCS) and the Canadian Association of General Surgeons (CAGS) and previous programs of their annual meetings were reviewed. Leadership positions, conference speakers, and award winners were categorized by race and sex. RESULTS: White males made up the largest category of Cardiac Surgery meeting speakers (73/142 [51%]), CAGS committee members (89/198 [45%]), CAGS past presidents (38/43 [88%]), and General Surgery meeting speakers (841/1472 [57%]). Of the 17 members that made up the CSCS board of directors and officers, 8 were White males (47%), 5 were BIPOC males (29%), 3 were White females (18%), and 1 was a BIPOC female (6%). Of the 42 members of the CAGS board of directors and advisory committee, 16 were White males (38%), 5 were BIPOC males (12%), 17 were White females (40%), and 4 were BIPOC females (10%). CONCLUSIONS: BIPOC individuals and females are underrepresented in both societies compared to White males. However, in CAGS, improvements in representation can be seen in recent years. It is important that both of these organizations continue to embrace diversity.

Sex and racial diversity in Canadian academic surgery.

To ensure equitable representation of women and BIPOC (Black, Indigenous, person of colour) individuals in surgical specialties, it is first necessary to understand the presence and extent of the disparities that exist. We explored the websites of the 17 Canadian faculties of medicine to examine sex and racial diversity in surgical specialties and in surgical leadership positions in Canada. We categorized faculty members of each department of surgery as either male or female and White or BIPOC. The relative percentage of female academic surgeons was very low compared with Canadian demographic data, and the relative percentage of BIPOC academic surgeons was similar to Canadian demographic data. Our observations suggest that actions must be taken to improve diversity and inclusion in surgery.

Diversity in National Society Leadership and Podium Speakers in Cardiothoracic Surgery.

BACKGROUND: Women and people of color are often underrepresented in medicine. This study examined the inclusivity and diversity of the recent history of the Canadian Association of Thoracic Surgeons (CATS) in both its executive committees and invited participation at its annual meeting. METHODS: CATS internal records and previous programs of CATS annual meetings were reviewed from 1997 to 2020. Leadership positions, invited speakers, and award recipients were categorized by sex and race. RESULTS: Of 199 CATS members in 2020, 93 (47%) were White men, 64 (32%) were men of color, 24 (12%) were White women, and 18 (9%) were women of color. The majority of CATS presidents (86%), committee chairs (57%), named lecturers (88%), other invited speakers (67%), and major award winners (90%) were White men. Women and people of color were underrepresented. The Resident Research Award was the most diverse: of 23 awards, 10 (44%) have been to men of color, 6 (26%) to White men, 4 (15%) to women of color, and 2 (8%) to White women. CONCLUSIONS: There is a need for more representation and inclusion of both women and people of color at multiple levels in CATS. This includes opportunities for improvement in the make-up of its executive committees, the speakers at its annual conference, and the recipients of its awards. CATS has established an Equity, Diversity and Inclusion Task Force to address this critical issue.
