Preoperative coagulation abnormalities as a risk factor for adverse events after pancreas surgery

Association of age with perioperative morbidity among patients undergoing surgical management of minor burns

Introduction

Burn injuries are associated with significant morbidity, often necessitating surgical management. Older patients are more prone to burns and more vulnerable to complications following major burns. While the relationship between senescence and major burns has already been thoroughly investigated, the role of age in minor burns remains unclear. To better understand differences between elderly and younger patients with predominantly minor burns, we analyzed a multi-institutional database.

Methods

We reviewed the 2008-2020 ACS-NSQIP database to identify patients who had suffered burns according to ICD coding and underwent initial burn surgery.

Results

We found 460 patients, of which 283 (62%) were male and 177 (38%) were female. The mean age of the study cohort was 46 ± 17 years, with nearly one-fourth (n = 108; 23%) of all patients being aged ≥60 years. While the majority (n = 293; 64%) suffered from third-degree burns, 22% (n = 99) and 15% (n = 68) were diagnosed with second-degree burns and unspecified burns, respectively. An average operation time of 46 min, a low mortality rate of 0.2% (n = 1), a short mean length of hospital stay (1 day), and an equal distribution of in- and outpatient care (51%, n = 234 and 49%, n = 226, respectively) indicated that the vast majority of patients suffered from minor burns. Patients aged ≥60 years showed a significantly prolonged length of hospital stay (p<0.0001) and were significantly more prone to non-home discharge (p<0.0001). In univariate analysis, advanced age was found to be a predictor of surgical complications (p = 0.001) and medical complications (p = 0.0007). Elevated levels of blood urea nitrogen (p>0.0001), creatinine (p>0.0001), white blood cell count (p=0.02), partial thromboplastin time (p = 0.004), and lower levels of albumin (p = 0.0009) and hematocrit (p>0.0001) were identified as risk factors for the occurrence of any complication. Further, complications were more frequent among patients with lower body burns.

Discussion

In conclusion, patients ≥60 years undergoing surgery for predominantly minor burns experienced significantly more complications. Minor lower body burns correlated with worse outcomes and a higher incidence of adverse events. Decreased levels of serum albumin and hematocrit and elevated values of blood urea nitrogen, creatinine, white blood count, and partial thromboplastin time were identified as predictive risk factors for complications.

Risk of venous thromboembolism in patients with elevated INR undergoing hepatectomy: an analysis of the American college of surgeons national surgical quality improvement program registry

BACKGROUND

Patients undergoing hepatectomy can have elevated INR and may have venous thromboembolism (VTE) prophylaxis withheld as a result. We sought to examine the association between preoperative INR elevation and VTE following hepatectomy.

METHODS

Hepatectomies captured in the American College of Surgeons National Surgical Quality Improvement Program registry between 2007 and 2016 were analyzed. Univariable and multivariable models examined the effect of incremental increases in preoperative INR on 30-day VTE, perioperative transfusion, serious morbidity, and mortality, adjusting for potential confounders.

RESULTS

We included 25,220 elective hepatectomies (62.4% partial lobectomies, 10.1% left hepatectomies, 18.6% right hepatectomies, 9.2% trisegmentectomies). The median age of the patients was 60 years and 49% were male. INR was elevated in 3089 patients (12.2%): 1.1-1.2 in 8.1%, 1.2-1.4 in 3.3%, and 1.4-2.0 in 0.9%. Incremental elevations in INR were independently associated with increasing risk for postoperative VTE [odds ratio (OR) 1.15, 95% confidence intervals 1.01-1.31], perioperative transfusion [OR 1.35 (1.28-1.43)], serious morbidity [OR 1.35 (1.28-1.43)], and mortality [OR 1.76 (1.56-1.98)].

CONCLUSION

Elevation in preoperative INR was counter-intuitively associated with increased risk of both VTE and perioperative transfusion following hepatectomy. The role of perioperative thromboprophylaxis warrants further investigation to determine optimal care in patients with elevated preoperative INR.

Perioperative outcomes of reconstructive surgery for apical prolapse in the very elderly: a national contemporary analysis

INTRODUCTION AND HYPOTHESIS

It is predicted that the number of women aged 80 years or older will more than triple by 2050. In the US, women have a 13% lifetime risk of undergoing pelvic organ prolapse surgery. Our aim was to compare the perioperative outcomes following various reconstructive approaches for apical prolapse surgery in the very elderly.

METHODS

The National Surgical Quality Improvement Program database was used to identify women age ≥ 80 years of age who underwent reconstructive apical prolapse surgery from 2010 to 2017. Perioperative morbidity of vaginal colpopexy, minimally invasive sacrocolpopexy (MISC) and abdominal sacrocolpopexy (ASC) were compared. The primary outcome was the rate of composite serious complications. Univariate and multivariate logistic regression was used to identify independent predictors of serious complications.

RESULTS

A total of 1012 patients were identified: vaginal (n = 792), MISC (n = 151) and ASC (n = 69). The composite serious complication rate was higher in the ASC group compared to vaginal/MISC groups (18.8% vs. 9.3% and 9.3%, p < 0.05). ASC had higher rates of blood transfusion, thromboembolism and reintubation. Life-threatening complications, readmission, pneumonia, stroke and 30-day mortality were lowest in the vaginal group. ASC (aOR 2.27), age > 85 years (aOR 1.98), operative time > 3 h (aOR 2.02), baseline dyspnea (aOR 2.17), "other race" (aOR 2.04), preoperative coagulopathy (aOR 2.92) and ASA (aOR 1.47) were associated with composite serious complications.

CONCLUSION

ASC is associated with higher perioperative morbidity in the very elderly population. MISC and vaginal colpopexy have similar rates of composite serious complications; however, vaginal colpopexy is overall the safest approach in this population.
