Outcomes of surgery in patients aged ≥90 years in the general surgical setting

Mortality 30, 60, and 90 Days After Discharge Is Greater in Patients Who Experienced Postoperative Respiratory Depression and Pulmonary Complication

Upon the induction of general anesthesia, a predictable sequence of physiological changes occurs within the respiratory and neuromuscular systems. The sequelae of these changes include an assortment of postoperative pulmonary complications (PPCs), including postoperative respiratory depression (PORD), that are observed during the immediate postoperative period and in the post-anesthesia care unit (PACU). These adverse events are anticipated, because several of the drugs that are used during surgery (e.g., opioids, which are traditionally used to manage pain during and after surgery), albeit therapeutically beneficial, have these adverse effects as part of their pharmacology. Nevertheless, the effects are traditionally considered transitory. However, several studies provide evidence suggesting that PPC-related morbidity and mortality extend 30, 60, and even 90 days after discharge from the hospital. These studies are summarized and assessed in this narrative review. Although exact estimates vary depending on the definitions used, the type of surgery, patient population, and risk factors (such as age), it is clear that PORD and other PPCs can be severe postoperative complications with significant associated mortality risks that extend weeks to months after discharge from the hospital.

Laparoscopic Gastric Gastrointestinal Stromal Tumor (GIST) Resection in a 108-Year-Old Patient

Surgery for centenarians comes with unprecedented challenges and risks. The limited physical reserve and fragility of homeostatic control in this population reduces their ability to adapt to physiological changes encountered during open and laparoscopic surgery. This case report presents a 108-year-old female patient who underwent laparoscopic resection of a symptomatic gastric gastrointestinal stromal tumour (GIST), without any adverse effects. The case highlights the importance of thorough preoperative risk assessment and planning, multidisciplinary input, and individualised patient care.

Urologic care of nonagenarians A retrospective chart review

INTRODUCTION

Nonagenarians represent a rapidly growing patient population in Canada and have unique health concerns. With the goal of preparing urologists to manage this complicated patient population in the future, we sought to characterize referral patterns, diagnoses, investigations, treatments, and associated complications in a cohort of nonagenarians. Our second goal was to review anticholinergic burden (ACB) and rates of anticoagulation in this patient population and to assess the risk of hematuria in those who were anticoagulated.

METHODS

This was a single-center, retrospective chart review of a sample of nonagenarians referred to our tertiary care center between 2009 and 2017. Demographic information, referral patterns, investigations, treatment plans, and outcomes were assessed. We assessed medication lists to calculate ACB scores at the time of referral, in addition to rates of anticoagulation use.

RESULTS

Data was collected for 154 nonagenarians. Hematuria was the most common reason for referral (n=43, 27.9%). Urinary retention and lower urinary tract symptoms (LUTS) were seen in 22 and 36 patients, respectively. The majority of patients underwent routine investigations; however, treatment decisions were frequently based on age and frailty. Mild, moderate and severe ACB scores were seen in 76.6%, 9.33%, and 14.0% of patients, respectively. Of those referred for hematuria, 78.1% were on anticoagulation therapy.

CONCLUSIONS

The most common reasons for urologic referral of nonagenarians include hematuria and LUTS. Most nonagenarians are offered routine investigations, and many are offered minor interventions for common benign and malignant urologic diagnoses. When treating nonagenarians, an individualized patient-centered care approach is likely most appropriate.

Safety of craniotomy for brain tumor resection in octogenarians and older patients - a matched - cohort analysis

INTRODUCTION

The incidence of brain tumors has increased in elderly population overtime. Their eligibility to a major surgery remains a questionable subject. This study evaluated prognostic factors and 30-days morbidity and mortality in octogenarian population who underwent craniotomy for resection of brain tumor.

MATERIALS AND METHODS

A total of 154 patients were divided into two different groups: patients above 80 years old and patients below 65 years old. In both groups, patients were stratified based on diagnosis with benign tumors [meningioma] and malignant tumors [high-grade gliomas and metastases]. Multivariable logistic regression model with backward elimination method was utilized to identify the independent risk factors for 30-days readmission and post-operative complications.

RESULTS

The analysis revealed no significant difference in 30-day readmission (p = 0.7329), 30-day mortality (0.6854) or in post-operative complication (p = 0.3291) between age ≥ 80 and age ≤ 65 groups. A longer length of stay (LOS) was observed in the older patients (p = 0.0479). There was a significant difference in the pre-post KPS between the two groups (p < 0.0001). ASA (p = 0.0315) and KPS (p = 0.071) were found as important prognostic factors associated with post-operative mortality in both groups.

CONCLUSION

Octogenarians can withstand craniotomy without any significant increase in 30-day readmission, 30-day mortality and post-operative complications as compared to patients younger than age 65. The ASA score (>3) and/or KPS (<70) were the most important prognostic factors for 30-days readmission and mortality.

Predictors of emergency abdominal surgery for patients aged 90 years or older: A retrospective study

Background

With the aging of the population, more and more patients ≥90 years old are undergoing surgery. We retrospectively examined factors affecting morbidity and in-hospital mortality among patients ≥90 years old who underwent emergency abdominal operations.

Materials and methods

Forty-six cases of emergency abdominal surgery for patients ≥90 years old who underwent surgery at our hospital between 2011 and 2022 were included in this study. Factors affecting morbidity and in-hospital mortality were analyzed statistically. Physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM)-predicted morbidity and Portsmouth-POSSUM (P-POSSUM)-predicted mortality were calculated.

Results

Postoperative complications occurred in 30 patients (65.2 %) and 5 patients (10.8 %) died in the hospital. Factors affecting morbidity included American Society of Anesthesiologists physical status score, operative time and blood loss, and operative severity score. Multivariate analysis identified male sex, operative severity score, and length of hospital stay as factors affecting morbidity. Eastern Cooperative Oncology Group performance status and physiological score were identified as factors influencing mortality in hospital, and only physiological score was identified in the multivariate analysis. Area under the receiver operating characteristic (ROC) curve for POSSUM-predicted morbidity was 0.796 and area under the ROC curve for P-POSSUM-predicted mortality was 0.805, both of which were moderately accurate.

Conclusion

Risk of emergency abdominal surgery in patients ≥90 years old may be predictable to some extent, and we are able to provide convincing explanations to patients and families based on these data.

Mortality burden from variation in provision of surgical care in emergency general surgery: a cohort study using the National Inpatient Sample

Background

The decision to undertake a surgical intervention for an emergency general surgery (EGS) condition (appendicitis, diverticulitis, cholecystitis, hernia, peptic ulcer, bowel obstruction, ischemic bowel) involves a complex consideration of factors, particularly in older adults. We hypothesized that identifying variability in the application of operative management could highlight a potential pathway to improve patient survival and outcomes.

Methods

We included adults aged 65+ years with an EGS condition from the 2016-2017 National Inpatient Sample. Operative management was determined from procedure codes. Each patient was assigned a propensity score (PS) for the likelihood of undergoing an operation, modeled from patient and hospital factors: EGS diagnosis, age, gender, race, presence of shock, comorbidities, and hospital EGS volumes. Low and high probability for surgery was defined using a PS cut-off of 0.5. We identified two model-concordant groups (no surgery-low probability, surgery-high probability) and two model-discordant groups (no surgery-high probability, surgery-low probability). Logistic regression estimated the adjusted OR (AOR) of in-hospital mortality for each group.

Results

Of 375 546 admissions, 21.2% underwent surgery. Model-discordant care occurred in 14.6%; 5.9% had no surgery despite a high PS and 8.7% received surgery with low PS. In the adjusted regression, model-discordant care was associated with significantly increased mortality: no surgery-high probability AOR 2.06 (1.86 to 2.27), surgery-low probability AOR 1.57 (1.49 to 1.65). Model-concordant care showed a protective effect against mortality (AOR 0.83, 0.74 to 0.92).

Conclusions

Nearly one in seven EGS patients received model-discordant care, which was associated with higher mortality. Our study suggests that streamlined treatment protocols can be applied in EGS patients as a means to save lives.

Should We Operate Nonagenarians with Symptomatic Giant Paraesophageal Hernias?

Introduction: Hiatal hernia (HH) is a common disorder of the upper gastrointestinal (UGI) tract that general surgeons encounter. Giant paraesophageal is a subtype of HH in which more than 30% of the stomach is located in the chest. It can cause symptoms such as dysphagia, UGI bleeding, gastroesophageal reflux disease, and vomiting. As the life expectancy of the general population increases, the incidence of giant HH increases and can cause morbidity, including recurrent admissions and prolonged length of hospitalization. In this article, we describe a cohort of nonagenarian patients with HH who were admitted to our institution and were treated either surgically or medically. Methods: We retrospectively reviewed our prospectively maintained database of all nonagenarians who were admitted to our center between 2018 and 2022 with the diagnosis of HH. We compared the demographic data, clinical data, and outcomes between patients undergoing operative and nonoperative management. Results: Twenty patients of age over 90 years were hospitalized with HH-related symptoms. Six underwent surgery, whereas 14 received medical management. Surgical patients had fewer overall hospitalization days, shorter length of stay, and less blood product requirements. Notably two cases of in-hospital mortality occurred in the nonoperative group, whereas none occurred in the operative group. All surgical procedures were performed laparoscopically, with two minor perioperative complications. Conclusion: In selected nonagenarian patients, laparoscopic HH repair is safe and should be considered favorably. It can reduce hospitalization time and can mitigate morbidity.

Effect of emergency general surgery on postoperative performance status in patients aged over 90 years

Background

Functional deterioration following emergency general surgery (EGS) poses a significant challenge in super-elderly patients. However, limited research has focused on assessing the deterioration in postoperative performance status (PS). This study aimed to investigate the impact of EGS on PS deterioration in super-elderly patients, and the extent to which deteriorated PS is recovered.

Methods

This historical cohort study comprised 77 super-elderly patients who underwent EGS between July 2015 and December 2020. Functional deterioration was evaluated by comparing preoperative and postoperative Eastern Cooperative Oncology Group Performance Status (ECOG-PS). The Emergency Surgical Score (ESS) was used as a risk-adjustment tool. Questionnaires were mailed to the patients and their families to assess post-discharge PS and obtain their impressions of EGS.

Results

Postoperative PS deteriorated in 35/77 patients (45.5 %). Significant differences were observed between the groups in terms of sex, serum C-reactive protein (CRP) levels, ESS scores, preoperative ECOG-PS, duration of operation, and major complications. Multivariate analysis of preoperative factors showed that ESS ≥7 (OR: 3.7, 95 % CI: 1.0-13), preoperative ECOG-PS ≤2 (OR: 5.9, 95 % CI: 1.7-21), and female sex (OR: 5.8, 95 % CI: 1.6-21) were associated with postoperative ECOG-PS deterioration. According to the questionnaire results, PS recovery post-discharge was observed in 6/36 (17 %) patients, and 34/36 (94 %) patients and their families expressed positive impressions of EGS.

Conclusions

EGS in super-elderly patients highly caused a deterioration in their PS, particularly in patients with maintained preoperative PS. PS hardly recovered; however, most patients and their families had positive impressions of the EGS.

Key message

We assessed the pre- and postoperative performance status of super-elderly patients who underwent emergency general surgery. Surgery caused a marked deterioration in patients' functional performance, which seldom recovered postoperatively.

Relationship between the m-FI 11 score and 2-year survival in octogenarians undergoing colorectal cancer resection

Introduction

The modified Frailty Index (m-FI) offers a simple scoring tool, predicting short-term outcomes in elderly colorectal cancer (CRC) patients. However, links between m-FI scores and 2-year postoperative mortality in octogenarian CRC resection patients remain underexplored. A streamlined frailty index can aid in preoperative assessments to identify elderly patients who are likely to live longer after curative resection surgery to then tailor postoperative care. Our study aims to assess the association between m-FI scores and 2-year postoperative mortality in elderly CRC surgery patients.

Methods

A retrospective analysis was conducted on a cohort of consecutive patients aged older than or equal to 80 years who underwent colorectal cancer resection at a tertiary referral centre between 2010 and 2017. The m-FI-11 scores less than or equal to two denoted the non-frail category, whereas m-FI scores equal to or exceeding 3 were categorised as frail. The primary outcome measure was defined as 2-year all-cause mortality.

Results

A total of 337 patients were studied. The 2-year overall survival rate was 83% with an overall median survival time of 84 months (95% CI: 74-94 months). Patients with m-FI scores less than or equal to 2 had a 2-year survival rate of 85% and a median survival time of 94 months (95% CI: 84-104 months). Conversely, patients with m-FI scores greater than or equal to 3 had a 2-year survival rate of 72% and a median survival time of 69 months (95% CI: 59-79 months). An m-FI score greater than or equal to 3 showed a hazard ratio of 1.73 (95% CI: 0.92-3.26, P=0.092) for 2-year mortality compared to an m-FI score less than or equal to 2.

Conclusion

Higher m-FI scores significantly correlate with an increased 2-year mortality risk among octogenarian CRC resection patients. This highlights the potential of the m-FI as a preoperative tool for identifying patients likely to survive longer post-surgery. Its integration aids in tailored postoperative care strategies, ensuring efficient recovery to functional baselines in this cohort.

Assessing and managing frailty in emergency laparotomy: a WSES position paper

Many countries are facing an aging population. As people live longer, surgeons face the prospect of operating on increasingly older patients. Traditional teaching is that with older age, these patients face an increased risk of mortality and morbidity, even to a level deemed too prohibitive for surgery. However, this is not always true. An active 90-year-old patient can be much fitter than an overweight, sedentary 65-year-old patient with comorbidities. Recent literature shows that frailty-an age-related cumulative decline in multiple physiological systems, is therefore a better predictor of mortality and morbidity than chronological age alone. Despite recognition of frailty as an important tool in identifying vulnerable surgical patients, many surgeons still shun objective tools. The aim of this position paper was to perform a review of the existing literature and to provide recommendations on emergency laparotomy and in frail patients. This position paper was reviewed by an international expert panel composed of 37 experts who were asked to critically revise the manuscript and position statements. The position paper was conducted according to the WSES methodology. We shall present the derived statements upon which a consensus was reached, specifying the quality of the supporting evidence and suggesting future research directions.

In their own words: recovery after emergency general surgery in the older patient

Objectives

Emergency general surgery (EGS) conditions, such as perforated intestines or complicated hernias, can lead to significant postoperative morbidity and mortality. We sought to understand the recovery experience of older patients at least 1 year after EGS to identify key factors for a successful long-term recovery.

Methods

We conducted semi-structured interviews to explore recovery experiences of patients and their caregivers after admission for an EGS procedure. We screened patients who were aged 65 years or older at the time of an EGS operation, admitted at least 7 days, and still alive and able to consent at least 1 year postoperatively. We interviewed the patients, their primary caregiver, or both. Interview guides were developed to explore medical decision making, patient goals and expectations surrounding recovery after EGS, and to identify barriers and facilitators of recovery. Interviews were recorded and transcribed, and we used an inductive thematic approach to analysis.

Results

We performed 15 interviews (11 patients and 4 caregivers). Patients wanted to return to their prior quality of life, or 'get back to normal.' Family was key in providing both instrumental support (eg, for daily tasks such as cooking, driving, wound care) and emotional support. Provision of temporary support was key to the recovery of many patients. Although most patients returned to their prior lifestyle, some also experienced depression, persistent abdominal effects, pain, or decreased stamina. When asked about medical decision making, patients expressed viewing the decision for having an operation not as a choice but, rather, the only rational option to treat a severe symptom or life-threating illness.

Conclusions

There is an opportunity in healthcare to provide better education for older patients and their caregivers around instrumental and emotional support to bolster successful recovery after emergency surgery.

Risk factors of serious postoperative outcomes in patients aged ≥90 years undergoing surgical intervention

Objective

We aimed to identify preoperative and intraoperative factors associated with serious postoperative outcomes, which may help patients and clinicians make better-informed decisions.

Methods

We conducted a retrospective study including all patients aged ≥90 years who underwent surgery between January 1, 2011, and January 1, 2021, at Chongqing University Central Hospital. We assessed 30 pre- and intraoperative demographic and clinical variables. Logistic regression was used to identify the independent risk factors for serious postoperative outcomes in patients aged ≥90 years.

Results

A total of 428 patients were included in our analysis. The mean age was 92.6 years (SD ± 2.6). There were 240 (56.1%) females and 188 (43.9%) males. The most common comorbidities were hypertension (44.9%) and arrhythmias (34.8%). The 30-day hospital mortality was 5.6%, and severe morbidity was 33.2%. Based on the multivariate logistic regression classification analysis of the American Society of Anesthesiologists (ASA)≥ Ⅳ [odds ratio (OR), 5.39, 95% confidence interval (CI), 2.06-14.16, P = .001], emergency surgery (OR, 5.02, 95% CI, 2.85-15.98, P = .001) and chronic heart failure (OR, 6.11, 95% CI, 1.93-13.06, P = .001) were identified as independent risk factors for 30-day hospital mortality, and ASA≥ Ⅳ (OR, 4.56, 95%CI, 2.56-8.15, P < .001), Barthel index (BI) < 35 (OR, 2.28, 95%CI, 1.30-3.98, P = .001), chronic heart failure (OR, 3.67, 95%CI, 1.62-8.31, P = .002), chronic kidney disease (OR, 4.24, 95%CI, 1.99-9.05, P < .001), general anesthesia (OR, 3.31, 95%CI, 1.91-5.76, P < .001), emergency surgery (OR, 3.72, 95%CI, 1.98-6.99, P < .001), and major surgery (OR, 3.44, 95%CI, 1.90-6.22, P < .001) were identified as independent risk factors for serious postoperative complications.

Conclusions

Patients aged ≥90 years with ASA≥ Ⅳ, BI < 35, combined with chronic heart failure or chronic kidney disease, undergoing emergency surgery, major surgery or general anesthesia have a higher risk of serious postoperative outcomes. Identifying these risk factors in an early stage may contribute to our clinical decision-making and improve the quality of treatments.

Treatment Strategy for Elderly Patients with Soft Tissue Sarcoma

PURPOSE OF REVIEW

Surgical resection is the standard treatment for localized soft tissue sarcoma (STS), while systemic chemotherapy for advanced STS may be considered. However, less aggressive treatment is often administered to elderly patients with STS. Undertreatment may compromise the cure rate and survival of these individuals. We review the literatures and emphasize the importance of standard treatment for STS in elderly patients.

RECENT FINDINGS

The outcome of surgical resection of STS in older individuals is comparable to that of younger ones, as long as patients are selected based on American Society of Anesthesiologists Physical Status (ASA-PS). Likewise, systemic treatment may prove beneficial as long as the risk of complications is estimated with a geriatric assessment. Elderly patients with STS benefit from standard treatment as long as the risks of surgical and systemic complications are assessed respectively with the ASA-PS and GA. Novel clinical trials with broader eligibility criteria are also necessary for elderly patients because of the increasing population of the elderly patients in the future.

Outcomes of surgery in patients 90 years of age and older: A retrospective cohort study

BACKGROUND

Important trade-offs of risks versus benefits of surgery need to be discussed with older adults, in particular nonagenarians who are candidates for surgery. Data that examine specific outcomes of surgical interventions in this age group are sparse. We aimed to evaluate the clinical presentation and postoperative outcomes of nonagenarians undergoing surgery.

METHODS

A retrospective cohort study of consecutive patients 90 years of age and older who underwent surgery between 2014 and 2018 in general surgical ward of a large-volume academic center. Subgroups were designed according to type of surgery (elective versus emergency surgery) and diagnosis (oncology versus non-oncology). Preoperative assessments included Malnutrition Universal Screening Tool, Norton Scale, Morse Scale, Katz, and Lawton-Brody indices.

RESULTS

A total of 198 nonagenarians underwent surgery, of which 38% were elective and 62% were emergency surgery. Median follow-up was 26 months. More patients in the elective group compared with the emergency group had oncology diagnoses (42.1% and 14.7%, respectively, P < .001), resided preoperatively at home (93.4% and 77.9%, respectively, P = .003), and were functionally independent (71.1% and 41.8%, respectively, P = .0005). Postoperative 30-day mortality frequency was 6.6% in the elective group and 39.3% in the emergency group (P < .001). Two-year survival frequency of non-oncology group was 72.7% in elective surgeries and 40.6% in emergency surgeries (P < .001). Two-year survival frequency of oncology group was 37% in elective surgeries and 27.8% in emergency surgeries (P = .12).

CONCLUSION

Elective surgery in adults aged 90 and above can be safely performed with acceptable 2-year outcomes. Emergency surgery for oncology diagnoses carries dismal outcomes, so palliative approaches should be considered.

Geriatric Patients Undergoing Outpatient Surgery in the United States: A Retrospective Cohort Analysis on the Rates of Hospital Admission and Complications

INTRODUCTION

 This study is a retrospective cohort analysis that describes key clinical outcomes in elderly individuals who undergo outpatient surgical procedures. In particular, we report same-day admission, 30-day mortality, 30-day complications, and 30-day readmission rates for three separate age groups undergoing frequent outpatient, general surgical procedures.

METHODS

Patients ≥18 years old who underwent the 10 most common outpatient surgical procedures in the National Surgical Quality Improvement Program database from 2017 to 2019 and who underwent general anesthesia were included in the study. The primary outcome of interest was hospital admission, defined as hospital length of stay >0 days. Secondary outcomes of interest included 30-day readmission, 30-day mortality, and 30-day postoperative complications. The primary exposure variable of interest was age, which was divided into <65 years of age (reference cohort), 65-79 years of age, and ≥80 years of age. For univariate analysis, to measure differences in the outcomes and patient characteristics, we used chi-squared tests. Our primary method of analysis was multivariable logistic regression.

RESULTS

Those who were ≥80 and 65-79 years of age compared to <65 years of age had higher odds of same-day admission, 30-day mortality, composite postoperative complications, and readmission. Patients who were ≥80 years old had higher odds of same-day admission for laparoscopic cholecystectomy, partial mastectomy, laparoscopic inguinal hernia repair, inguinal hernia repair, umbilical hernia repair, laparoscopic removal of adnexal structures, and lumbar laminotomy.

CONCLUSION

Increasing age, particularly greater than 80 years or older and 65-79 years of age group, is associated with an increased rate of same-day hospital admissions and complications after ambulatory surgery.

Non-traumatic emergency abdominal surgery in nonagenarian patients: a retrospective study

PURPOSE

The primary aim of this study was to evaluate the 30-day survival of nonagenarian patients who underwent non-traumatic emergency abdominal surgery. Other aims were: 90-day and 12-month survival rates, the postoperative complications rate, the impact of the emergency operation on postoperative functional status, the accuracy of the P-POSSUM in predicting 30-day postoperative mortality and changes in care services after surgery.

METHODS

This was a retrospective cohort study of nonagenarian patients who underwent non-traumatic emergency abdominal surgery between January 2010 and June 2017. Patients were divided in two groups according to the 30-day survival status to compare the distribution of patients' characteristics and postoperative outcomes. Overall survival was estimated using the Kaplan-Meier method. To assess the accuracy of P-POSSUM to predict 30-day mortality, a receiver operating characteristic curve and the Hosmer-Lemeshow goodness of fit test were used.

RESULTS

85 nonagenarian patients were enrolled in this study; of these, 27 (31.8%) died within 30 days. The Kaplan-Meier curve showed a rapid decline in survival over the first 30 postoperative days, followed by a more gradual reduction during the rest of the first year. The majority of patients (92.6%) who died within 30 days experienced a medical complication, with a preponderance of respiratory failure (48.2%) and multiple organ failure (33.3%). In the surviving patients, the postoperative functional status had worsened, and 64.2% of patients did not return to their original housing situation or were institutionalized. The accuracy of P-POSSUM in predicting 30-day mortality in nonagenarian patients was poor.

CONCLUSIONS

This study may help doctors convey the postoperative risks of morbidity and mortality, and also to adequately inform relatives about the possible adverse discharge destination of surviving nonagenarian patients with a consequent increase in care needs.

Does Major Pancreatic Surgery Have Utility in Nonagenarians with Pancreas Cancer?

OBJECTIVE

This study aims to define the role of surgery and assess different therapies for nonagenarians with localized, nonmetastatic pancreatic adenocarcinoma (PDAC).

METHODS

The National Cancer Database (NCDB) was queried for patients ≥ 90 years of age with nonmetastatic, localized PDAC from 2004-2016. Postoperative mortality was assessed at 30 and 90 days in patients receiving pancreatoduodenectomy or total pancreatectomy. Overall survival (OS) was compared between three treatment groups: surgery alone, chemotherapy alone, and chemoradiation (chemoRT) alone.

RESULTS

Of 380,524 patients with PDAC, 98 patients ≥ 90 years of age underwent curative-intent resection; 55% were female and 75% had a Charlson-Deyo comorbidity score of 0. A total of 17% received postoperative chemotherapy, 51.1% had poorly differentiated tumors with a median tumor size of 3 cm, 55.1% had positive lymph nodes, and 19.4% had positive resection margins. Postoperative median length of stay was 11 days. Postoperative 30- and 90-day mortality was 10.0% and 18.9%, respectively. Median OS for the surgery alone group was 11.6 months compared with 20.4 months in those receiving adjuvant therapy (p = 0.01). Among nonoperative PDAC patients, median OS in patients receiving chemotherapy only (n = 207) was 7.2 months, while chemoRT only (n = 100) was similar to surgery only (11 versus 11.6 months, p = 0.97).

CONCLUSIONS

Even in well-selected nonagenarians, pancreatoduodenectomy or total pancreatectomy carries a high mortality rate. While adjuvant therapy after resection provides the best survival, it is seldom achieved, and chemoRT alone affords identical survival statistics as surgery alone. These data suggest it is reasonable to consider chemoRT as initial therapy, then reassess candidacy for resection if performance status allows.

Results of the Surgical Management of Acute Limb Ischemia in the Nonagenarians

BACKGROUND

The aging of the population leads us to treat older patients, in particular presenting with acute limb ischemia (ALI). However, there has been little evaluation of this pathology in the nonagenarians. The objectives of this work are thus to evaluate the 1-month and 1-year mortality of the nonagenarians treated for ALI, which made possible to determine the 1-year survival and to highlight the factors influencing the mortality.

METHODS

This is a monocentric retrospective study including all the patients aged 90 years old or more surgically treated for ALI between January 2012 and December 2016. In all the patients, we recorded the 1-month mortality and the 1-year survival and the demographic, clinical, and paraclinical data.

RESULTS

We operated 83 nonagenarians, with a majority of women (59, 71.1%), using general anesthesia in 20 patients (16.6%), including 10 cases of upper limb acute ischemia (12.0%). The overall mortality rate at 1 month was 22.9%, and the 1-year survival rate was 43.4%. Major amputation rate was 9.6% at 1 year. The survival of the patients operated for upper or lower limb ischemia was similar (P = 0.82). Univariate analysis showed that the 1-year survival was lower in patients having a history of cerebrovascular problems (P = 0.0003), heart failure (P = 0.0027), dementia (P = 0.0452), or in patients that were institutionalized (P = 0.0125), invalid (P = 0.0001), or presented with a complete acute ischemia (P = 0.0002). In multivariate analysis, 3 risk factors remained statistically significant: a previous history of cerebrovascular accident (hazard ratio [HR] = 3.05 [1.54-6.02]; P = 0.0014), cardiac failure (HR = 2.21 [1.23-3.97]; P = 0.0083), and complete ALI (HR = 3.07 [1.64-5.75]; P = 0.0005).

CONCLUSIONS

Our study showed that a history of cerebrovascular accident, cardiac failure, or complete ALI is a poor prognostic factor for the 1-year survival of nonagenarians dealt operated for ALI. These elements should be taken into account when deciding either to operate or not in this precise context.

Sex does not have an impact on perioperative transfemoral carotid artery stenting outcomes among octogenarians

OBJECTIVE

Transfemoral carotid artery stenting (CAS) has been validated as an acceptable alternative to carotid endarterectomy in patients at high risk for open surgery. There are variable sex- and age-based differences in transfemoral CAS outcomes of published randomized controlled trials. The aim of our study was to evaluate sex-based differences in perioperative outcomes after transfemoral CAS performed in octogenarians.

METHODS

The National Surgical Quality Improvement Program targeted vascular module was queried for all patients ≥80 years of age who underwent transfemoral CAS between 2011 and 2017. Symptomatic status was defined as a history of prior ipsilateral stroke, transient ischemic attack, or amaurosis fugax. The primary outcome was a composite outcome of perioperative (30-day) stroke or death. Outcomes were compared for male vs female patients and stratified by symptomatic status using univariate and multivariable logistic regression analyses adjusting for emergent status, symptomatic status, comorbidities, and use of an embolic protection device.

RESULTS

Overall, there were 143 patients ≥80 years of age who underwent transfemoral CAS during the study period, including 95 men (66.4%) and 48 women (33.6%). Race (white, 88.0% vs 85.4%), symptomatic status (30.9% vs 29.2%), and degree of stenosis (severe, 71.6% vs 62.5%) were not significantly different for men vs women (P ≥ .27). Periprocedural stroke/death occurred in six men (6.4%) vs two women (4.2%; P = .59) and did not significantly differ when stratified according to symptomatic (6.9% vs 7.1%; P = .98) and asymptomatic (6.2% vs 2.9%; P = .49) status. Based on multivariable analysis, independent factors associated with the composite end point included emergent vs elective status (adjusted odds ratio OR [aOR], 20.3; 95% confidence interval [CI], 2.25-183) and failure to use an embolic protection device (aOR, 2.86; 95% CI, 1.59-50.0). Sex was not significantly associated with the primary outcome after risk adjustment (aOR, 0.81; 95% CI, 0.28-3.28).

CONCLUSIONS

We found no sex-based differences in risk of perioperative stroke/death among patients ≥80 years of age undergoing transfemoral CAS. Our study validates previous studies showing a high rate of perioperative complications after transfemoral CAS in octogenarians and suggests that the decision to use this technology in older patients should be determined by patients' anatomic and medical risk factors irrespective of sex.

Mortality after abdominal emergency surgery in nonagenarians

PURPOSE

To search the pattern of diagnoses in nonagenarians undergoing emergency abdominal surgery between January 2009 and December 2013 in two hospitals. To test the hypothesis that pre-hospital functional status is an effective criterion for predicting postoperative mortality in nonagenarians after emergency abdominal surgery.

METHODS

The study is an observational study on 157 patients. Patients were identified from the operation database and perioperative data were extracted as prospectively information supplied by retrospective data from patient electronic files. The primary endpoints were short, middle and long-term mortality and the secondary endpoint was to identify preoperative factors associated with postoperative mortality.

RESULTS

The most frequent reason for operation was intestinal obstruction. Overall mortality in the cohort was 34% (n = 54) after 30 days and 54% (n = 84) after 1 year. Amongst patients developing a serious complication (classified as Clavien Dindo class III or greater) after surgery (n = 45) the mortality was 80% (n = 36) after 30 days and 89% (n = 40) after 1 year. In multivariate analysis, a high American Association of Anesthesiologists class (ASA) and a high Performance Status (PS) class (low performance) were significant predictors of post-operative mortality.

CONCLUSION

Our data support pre-admission functional status for predicting postoperative mortality after emergency abdominal surgery in nonagenarians.
