Complicaciones postoperatorias y resultados clínicos en pacientes operados por cáncer torácico y gastrointestinal: Estudio de cohorte prospectivo / Postoperative complications and clinical outcomes among patients undergoing thoracic and gastrointestinal cancer surgery: A prospective cohort study

RESUMEN Objetivo: Determinar la influencia de las complicaciones postoperatorias sobre los resultados clínicos en pacientes operados por cáncer torácico y gastrointestinal. Métodos: Se realizó un estudio de cohorte prospectivo de 179 pacientes consecutivos que fueron operados de tórax o vías digestivas por cáncer y admitidos en una unidad de cuidados intensivos oncológicos. Se evaluó la incidencia de las complicaciones postoperatorias mediante el Postoperative Morbidity Survey y su influencia sobre la mortalidad y estadía hospitalaria. Resultados: Se presentaron complicaciones postoperatorias en 54 sujetos (30,2%); las más frecuentes fueron las pulmonares (14,5%), el dolor (12,9%), las cardiovasculares (11,7%), las infecciosas (11,2%) y las de la herida quirúrgica (10,1%). En el análisis multivariado de regresión logística las complicaciones pulmonares (OR 18,68; IC95% 5,59 - 62,39; p < 0,0001), cardiovasculares (OR 5,06; IC95% 1,49 - 17,13; p = 0,009), gastrointestinales (OR 26,09; IC95% 6,80 - 100,16; p < 0,0001), infecciosas (OR 20,55; IC95% 5,99 - 70,56; p < 0,0001) y renales (OR 18,27; IC95% 3,88 - 83,35; p < 0,0001) se relacionaron de forma independiente con la mortalidad hospitalaria. La ocurrencia de al menos una complicación incrementó la probabilidad de permanecer hospitalizado (Log Rank test; p = 0,002). Conclusiones: Las complicaciones postoperatorias son trastornos frecuentes y asociados con malos resultados clínicos, por lo que se deben realizar cambios estructurales y de proceso para reducir la morbilidad y mortalidad postoperatorias.

ABSTRACT Objective: This study sought to determine the influence of postoperative complications on the clinical outcomes of patients who underwent thoracic and gastrointestinal cancer surgery. Methods: A prospective cohort study was conducted regarding 179 consecutive patients who received thorax or digestive tract surgery due to cancer and were admitted to an oncological intensive care unit. The Postoperative Morbidity Survey was used to evaluate the incidence of postoperative complications. The influence of postoperative complications on both mortality and length of hospital stay were also assessed. Results: Postoperative complications were found for 54 patients (30.2%); the most common complications were respiratory problems (14.5%), pain (12.9%), cardiovascular problems (11.7%), infectious disease (11.2%), and surgical wounds (10.1%). A multivariate logistic regression found that respiratory complications (OR = 18.68; 95%CI = 5.59 - 62.39; p < 0.0001), cardiovascular problems (OR = 5.06, 95%CI = 1.49 - 17.13; p = 0.009), gastrointestinal problems (OR = 26.09; 95%CI = 6.80 - 100.16; p < 0.0001), infectious diseases (OR = 20.55; 95%CI = 5.99 - 70.56; p < 0.0001) and renal complications (OR = 18.27; 95%CI = 3.88 - 83.35; p < 0.0001) were independently associated with hospital mortality. The occurrence of at least one complication increased the likelihood of remaining hospitalized (log-rank test, p = 0.002). Conclusions: Postoperative complications are frequent disorders that are associated with poor clinical outcomes; thus, structural and procedural changes should be implemented to reduce postoperative morbidity and mortality.

The effect of preoperative carbohydrate administration on postoperative insulin resistance and immune function in patients after gastroenteric tumor resection / 中国医师杂志

Objective To investigate the effect of preoperative carbohydrate fluid intake on postoperative insulin resistance and immune function.Methods Sixty elective gastroenteric tumor resection patients were randomly divided into test (n =30) and control (n =30) groups.Control group were fasted before surgery,while test group were given oral carbohydrate before surgery.The blood samples were collected to measure the levels of fasting blood glucose (FBG),fasting insulin (FINS),and cellular immunity (CD3 +,CD4 +,CD8 +,and CD4 +/CD8 +) before operation and 1,3,7 day postoperation,respectively.Homeostasis model assessment (HOMA) was applied to assess the status of insulin resistance.Results Compared to preoperation,the levels of CD4 +,CD4 + / CD8 +,and HOMA-IR at 1 day postoperation in both control and test groups were significantly higher (P ＜ 0.05).Compared to test group,the levels of CD4 +,CD4 +/CD8 +,and HOMA-IR at 1,3 day postoperation in control group were significantly higher (P ＜ 0.05).At the seventh day after surgery,HOMA-IR levels in the test group were returned to the preoperative level (P ＞ 0.05),while the control group was still higher than before surgery (P ＜ 0.05).There were no differences in CD4 + and CD4+/CD8 + at seventh days after surgery between two groups (P ＞ 0.05).Conclusions Preoperative carbohydrate administration may shorten the insulin resistance duration after gastrointestinal cancer surgery,reduce the intensity of insulin resistance,and improve immune function.Thus contributes to the rehabilitation of patients.
