Experience in colorectal surgery at a quaternary care hospital in Bogotá, Colombia

INTRODUCTION AND AIMS

Colorectal cancer is among the three most common cancers worldwide. Knowledge and identification of suboptimal outcome-associated factors enable comprehensive patient management. The aim of the present study was to present the results of the surgical management of colorectal cancer at a quaternary care university hospital.

MATERIALS AND METHODS

An observational, analytic, cross-sectional study was conducted. Information was collected on a retrospective cohort of patients diagnosed with colorectal cancer from 2013 to 2017 at the Hospital Universitario Mayor Méderi, Bogotá, Colombia.

RESULTS

Data on 452 patients, within the study period, were collected. A total of 48.5% of the patients were men, the overall complication rate was 24%, the surgical site infection (SSI) rate was 15.38%, anastomotic dehiscence occurred in 4.18% of the patients, bleeding required reoperation in 1.32%, and the intrahospital mortality rate was 7.47%.

CONCLUSION

Colorectal cancer management at a university hospital was as beneficial as that provided by other types of hospitals, showing a direct association with complete R0 dissections; low complication rates, according to international reports; and reduced overall morbidity.

Transfusion needs in patients admitted for fracture of femur

OBJECTIVE

To determine the variables and predictive factors associated with the administration and frequency of the allogenic blood transfusion (ABT) on patients diagnosed with fracture of femur requiring surgical intervention. The secondary objective was to describe the frequency and quantity of ABT on those patients.

METHOD

A retrospective transversal observational study was performed on patients admitted to the Sagrat Cor hospital of Barcelona with a diagnosis of fractured femur that required surgical intervention in 2016. Several demographic variables were gathered along with the clinical data and outcome of transfused and non-transfused patients, including the type of fracture.

RESULTS

The overall sample was 257 patients. Of the patients studied, 52.9% required blood transfusion support. Patients who required ABT had haemoglobin values on admission of 11.01 gdl while those that did not require transfusion had an average value of 12.97 g/dl. Of the patients, 42.8% were on anticoagulant and/or antiplatelet therapy before the fracture occurred.

CONCLUSIONS

More than half the patients admitted for fracture of femur received blood transfusion. The data collected showed that the hospital transfusion policy offered satisfactory results. Factors associated with the need for ABT were haemoglobin levels on admission and the type of fracture. Age and ASA risk (classification system of the American Society of Anesthesiologists) were also risk factors for ABT. This information could be useful for blood saving protocols. Finally, we think that it is important that all patients that are hospitalised with a diagnosis of fracture of femur and require surgery have a blood reserve request made, given that a high percentage of them, at any time during their stay, will be transfused.

Risk factors for the development of complications after surgical treatment for bronchopulmonary carcinoma

INTRODUCTION

The most suitable treatment in most early-stage lung cancer patients is surgical resection. Despite previously assessing each patient's status being relevant to detect possible complications inherent to surgery, no consensus has been reached on which factors are "high risk" in such patients. Our study aimed to analyse the morbidity and the mortality incidence associated with this surgery in our setting with a multicentre study and to detect risk parameters.

METHODS

A prospective analysis study with 3,307 patients operated for bronchopulmonary carcinoma in 24 hospitals. Study variables were age, TNM, gender, stage, smoking habit, surgery approach, surgical resection, ECOG, neoadjuvant therapy, comorbidity, spirometric values, and intraoperative and postoperative morbidity and mortality. A multivariate logistic regression analysis of the morbidity and mortality predictor factors was done.

RESULTS

We recorded 34.2% postoperative morbidity and 2.1% postoperative mortality. Gender, myocardial infarction, angina, ECOG ≥1, COPD, DLCO <60%, clinical pathological status, surgical resection and surgery approach were shown as morbidity and mortality predictor factors in lung cancer surgery in our series.

CONCLUSIONS

The main variables to consider when assessing the lung cancer patients to undergo surgery are gender, myocardial infarction, angina, ECOG, COPD, DLCO, clinical pathological status, surgical resection and surgery approach.

Short- and long-term mortality in patients with left-sided infective endocarditis not undergoing surgery despite indication

INTRODUCTION AND OBJECTIVES

In infective endocarditis (IE), decisions on surgical interventions are challenging and a high percentage of patients with surgical indication do not undergo these procedures. This study aimed to evaluate the short- and long-term prognosis of patients with surgical indication, comparing those who underwent surgery with those who did not.

METHODS

We included 271 patients with left-sided IE treated at our institution from 2003 to 2018 and with an indication for surgery. There were 83 (31%) surgery-indicated not undergoing surgery patients with left-sided infective endocarditis (SINUS-LSIE). The primary outcome was all-cause death by day 60 and the secondary outcome was all-cause death from day 61 to 3 years of follow-up. Multivariable Cox regression and propensity score matching were used for the analysis.

RESULTS

At the 60-day follow-up, 40 (21.3%) surgically-treated patients and 53 (63.9%) SINUS-LSIE patients died (P <.001). Risk of 60-day mortality was higher in SINUS-LSIE patients (HR, 3.59; 95%CI, 2.16-5.96; P <.001). Other independent predictors of the primary endpoint were unknown etiology, heart failure, atrioventricular block, and shock. From day 61 to the 3-year follow-up, there were no significant differences in the risk of death between surgically-treated and SINUS-LSIE patients (HR, 1.89; 95%CI, 0.68-5.19; P=.220). Results were consistent after propensity score matching. Independent variables associated with the secondary endpoint were previous IE, diabetes mellitus, and Charlson index.

CONCLUSIONS

Two-thirds of SINUS-LSIE patients died within 60 days. Among survivors, the long-term mortality depends more on host conditions than on the treatment received during admission.

Postoperative intensive care unit admission does not affect outcomes in elective surgical patients with severe comorbidity

OBJECTIVE

The impact of postoperative intensive care upon patient outcomes was evaluated by retrospectively investigating the rate of poor outcomes among miscellaneous elective surgical patients with severe comorbidities.

DESIGN

A retrospective cohort study was carried out.

SETTING

University hospital.

PATIENTS

Surgical patients with severe comorbidities.

INTERVENTION

The outcomes of 1218 surgical patients treated in intensive care units (ICUs) and postsurgical wards (ICU group vs. non-ICU group) were reviewed for poor outcomes (i.e., no discharge or death). A propensity score analysis was used to generate 248 matched pairs of ICU-admitted patients and controls.

VARIABLES OF INTEREST

Poor outcome rates on postoperative day 90 and mortality on postoperative days 30 and 90.

RESULTS

No significant between-group differences were observed in terms of poor outcomes on postoperative day 90 [ICU vs. non-ICU: 33/248 (13%) vs. 28/248 (11%), respectively; ICU odds ratio (OR): 1.19, 95% confidence interval (CI), 0.71-2.01, p=0.596] or in between-group differences in terms of mortality on postoperative days 30 and 90 [ICU vs. non-ICU: 4/248 (1.6%) vs. 2/248 (0.8%) on postoperative day 30 and 5/248 (2.0%) vs. 3/248 (1.2%) on day 90, respectively; ICU OR (95% CI), 2.00 (0.37-10.9) and 1.67 (0.40-6.97) for postoperative 30- and 90-day mortality, respectively (p=0.683 and 0.724)]. Low preoperative body weight was negatively correlated to patient outcomes [OR (95% CI): 0.82/10kg (0.70-0.97), p=0.019], whereas regional analgesia combined with general anesthesia was positively correlated to patient outcomes [OR (95% CI): 0.39 (0.69-0.96), p=0.006]. Extra ICU admission was correlated to poor patient outcomes [OR (95% CI): 4.18 (2.23-7.81), p < 0.0001].

CONCLUSIONS

Postoperative ICU admission failed to demonstrate any meaningful benefits in patients with severe comorbidities undergoing miscellaneous elective surgeries.
