У 92 (31,8%) коморбидных пациентов индекс Чарлсона равнялся 2,4±1,1. У пациентов без коморбидных заболеваний — 1,1±0,8. Послеоперационные соматические осложнения развились в 57 случаях (19,7%), из них в группе коморбидных — у 22 человек (23,9%). Умерло 32 больных (11,1%). Кардиопульмональные осложнения возникли у всех 12 умерших пациентов с коморбидностью, у 6 они стали основной причиной смерти. Из 20 умерших некоморбидных пациентов соматические осложнения были зарегистрированы у 15 (75%), причиной смерти они стали у 6 (30%). Индекс Чарлсона у умерших коморбидной группы был 2,0±1,2, среди пациентов без коморбидног7нннннннн67гсти — 1,4±1,1 (р=0,01). Логистический анализ показал, что наличие коморбидности и индекс Чарлсона значимо влияли на исход заболевания (р=0,02) с отношением шансов 0,6 и на возникновение осложнений (р=0,04) — 0,9 и 0,7 соответственно. Отношение шансов наступления летального исхода равнялось 0,96 при наличии сердечно-сосудистой патологии, 0,3 — при легочной патологии и 0,04 — при наличии гепатита (р=0,0006), развития послеоперационных осложнений — 0,85; 0,64 и 0,09 соответственно (р=0,02). При развитии легочных осложнений отношение шансов наступления летального исхода составило 0,02, сердечно-сосудистых — 0,09 (р=0,0001). Прогностический нутритивный индекс не показал различий между группами.</p></sec><sec><title>Заключение</title><p>Заключение. Коморбидная патология имелась у трети пациентов, которым была выполнена эзофагопластика. Кардиопульмональные осложнения служат причиной смерти у половины умерших пациентов с коморбидной патологией. Коморбидность и индекс Чарлсона — чувствительные и объективные предикторы неблагоприятного исхода после эзофагопластики.</p></sec></abstract><trans-abstract xml:lang="en"><p>The purpose of the study was to assess the impact of comorbidity on esophagoplasty outcomes.</p><sec><title>Materials and methods</title><p>Materials and methods. The outcomes of 289 patients undergoing esophagoplasty for cancer (251) and benign diseases of the esophagus (48) were analyzed, the comorbidity, Charlson index and prognostic nutritional index were calculated.</p></sec><sec><title>Results</title><p>Results. Comorbid diseases were detected in 92 patients (31.8%), the Charlson index in this group was 2.4±1.1. In the group without comorbidity it was 1.1±0.8. Postoperative somatic complications developed in 57 cases (19.7%), in comorbid-ity group — 22 patients (23.9%), without comorbidity — 35 people (17.8%). 32 patients died (11.1%). Cardiopulmonary complications occurred in all 12 fatal outcomes in comorbid patients, in half of them they became the main cause of death. </p><p>Somatic complications were in 15 (75%) of 20 fatal outcomes in patients without comorbidity, they became the cause of death in 6 (30%). The Charlson index in comorbid group was 2.0±1.2 versus 1.4±1.1 in the other patients (p=0.01). The presence of comorbidity and the Charlson index signiﬁcantly inﬂ uenced the outcome of the disease (p=0.02) with logistic probability of 0.6 and a smaller logit spread, as well as the occurrence of complications in the postoperative period (p = 0.04) with values of 0.9 and 0.7, respectively. The logistic probability of a fatal outcome was 0.96 in cardiovascular pathology, 0.3 in pulmonary pathology, and 0.04 in hepatitis (p = 0.0006). The logistic probability of postoperative complications in cardiovascular pathology was 0.85, in pulmonary pathology — 0.64, in hepatitis — 0.09 (p = 0.02). The logistic probability of a fatal outcome with the development of pulmonary complications was 0.02, cardiovascular complications — 0.09 (p = 0.0001). The Onodera’s prognostic nutritional index in comorbid patients was 43±9, in others — 44±4 (p = 0.5).</p></sec><sec><title>Conclusion</title><p>Conclusion: comorbidity was detected in one third of patients who underwent esophagoplasty. Cardiopulmonary complications cause death in half of the deceased patients with comorbidity. The Charlson Index proved to be the most sensitive and objective predictor of outcomes in patients with comorbid diseases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эзофагопластика</kwd><kwd>коморбидность</kwd><kwd>индекс Чарлсона</kwd><kwd>осложнения</kwd><kwd>исход</kwd><kwd>нутритивный индекс Онодера</kwd></kwd-group><kwd-group xml:lang="en"><kwd>esophagoplasty</kwd><kwd>comorbidity</kwd><kwd>Charlson index</kwd><kwd>complications</kwd><kwd>outcome</kwd><kwd>Onodera nutritional index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Черноусов А.Ф., Богопольский П.
