Tracheal deviation was categorized as ≤5 mm, 6-10 mm, or >10 mm. Thyroid volume was calculated using the ellipsoid formula. Because no composite complications occurred in the ≤10-mm group, Firth bias-reduced logistic regression was performed. An exploratory model was adjusted additionally for age, sex, thyroid volume, gland distribution, thyroid functional status, thyroid autoantibody status, and retrosternal extension.Results: Composite complications occurred in 16 patients (17.8%), all from the >10-mm group. The median thyroid volume increased significantly across the deviation groups (210.5, 249.0, and 389.2 mL; p<0.001). Univariable Firth analysis showed a strong association between tracheal deviation >10 mm and composite complications (OR 50.90, 95% CI 6.44-6582.01; p<0.001). In the adjusted model, the association remained positive but was not significant (OR 8.91, 95% CI 0.28-1704.62; p=0.224).Conclusions: Tracheal deviation >10 mm identified patients at high crude risk for postoperative complications, but an independent association beyond thyroid volume, retrosternal extension, and other clinical factors was not demonstrated. Tracheal deviation should be interpreted together with other CT features of giant multinodular goiter.","PeriodicalId":22163,"journal":{"name":"Surgery Today","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149115295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were divided into those who required postoperative bronchoscopic sputum suction and those who did not. Clinicopathological factors, surgical outcomes, Brinkman Index, pulmonary function, and postoperative complications were compared.Results: Postoperative bronchoscopic sputum suction was required in 21 patients. All bronchoscopic procedures were performed after transfer from the intensive care unit to the general ward. The bronchoscopic group had a significantly higher Brinkman Index than the no-bronchoscopic group, whereas standard spirometric parameters, including forced vital capacity, forced expiratory volume in 1 s, and the forced expiratory volume in 1 s percentage, did not differ between the groups. Patients requiring bronchoscopy had higher rates of postoperative pneumonia and anastomotic leakage and a significantly longer postoperative hospital stay.Conclusion: In patients undergoing minimally invasive esophagectomy, greater cumulative smoking exposure was associated with rescue bronchoscopic sputum suction despite comparable preoperative spirometry.

The additional colonic length gained after each maneuver was measured under tension-free conditions. High inferior mesenteric artery (IMA) ligation, which sacrifices the LCA, was also measured as a reference comparator.Results: The mean baseline resection length was 10.4 ± 6.9 cm. Additional gains: 6.3 ± 1.7 cm after SFM and 14.4 ± 2.1 cm after high IMV ligation (maximum gain under LCA preservation). As a reference, high IMA ligation (without LCA preservation) provided a lengthening of 18.4 ± 1.7 cm. In malrotation (n = 2), IMV ligation yielded only 10.2-12.3 cm of mesenteric length. BMI correlated positively with the baseline length (r = 0.529, p = 0.023).Conclusions: Under LCA preservation, high IMV ligation provides the greatest lengthening (14.4 cm), although efficacy is reduced with malrotation.

Intraoperative Doppler ultrasonography was used to assess venous flow in spontaneous and anatomical liver positions.
