The virtual uncertainty of futility in emergency surgery

Characterisation of older patients that require, but do not undergo, emergency laparotomy: a multicentre cohort study

BACKGROUND

Older adults (≥65 yr) account for the majority of emergency laparotomies in the UK and are well characterised with reported outcomes. In contrast, there is limited knowledge on those patients that require emergency laparotomy but do not undergo surgery (NoLaps).

METHODS

A multicentre cohort study (n=64 UK surgical centres) recruited 750 consecutive NoLap patients (February 15th - November 15th 2021, inclusive of a 90-day follow up period). Each patient was admitted to hospital with a surgical condition treatable by an emergency laparotomy (defined by The National Emergency Laparotomy Audit (NELA) criteria), but a decision was made not to undergo surgery (NoLap).

RESULTS

NoLap patients were predominately female (452 patients, 60%), of advanced age (median age 83.0 yr, interquartile range 77.0-88.8), frail (523 patients, 70%), and had severe comorbidity (750 patients, 100%); 99% underwent CT scanning. The commonest diagnoses were perforation (26%), small bowel obstruction (17%), and ischaemic bowel (13%). The 90-day mortality was 79% and influencing factors were >80 yr, underweight BMI, elevated serum lactate or creatinine concentration. The majority of patients died in hospital (77%), with those with ischaemic bowel dying early. For the 21% of NoLap patients that survived to 90 days, 77% returned home with increased care requirements.

CONCLUSIONS

This study reports that the NoLap patient population present significant medical challenges because of their extreme levels of comorbidity, frailty, and physiology. Despite these complexities a fifth remained alive at 90 days. Further work is underway to explore this high-risk decision-making process.

Aplastic Anemia With Non-Occlusive Mesenteric Ischemia

This case highlights the multifaceted challenges of managing aplastic anemia, especially when complicated by non-occlusive mesenteric ischemia (NOMI). The patient's clinical course underscores the importance of a conservative, multidisciplinary approach in balancing the risks of invasive procedures with the need for effective diagnostics and treatment. Recognizing the risks associated with pancytopenia, including life-threatening bleeding and infections, is critical in managing such patients. Careful monitoring and timely interventions, particularly in an intensive care setting, are essential to improve outcomes in complex cases like this one.

The management of complicated colorectal cancer in older patients in a global perspective after COVID-19: the CO-OLDER WSES project

BACKGROUND

Colorectal (CRC) cancer is becoming a disease of the elderly. Ageing is the most significant risk factor for presenting CRC. Early diagnosis of CRC and management is the best way in achieving good outcomes and longer survival but patients aged ≥75 years are usually not screened for CRC. This group of patients is often required to be managed when they are symptomatic in the emergency setting with high morbidity and mortality rates. Our main aim is to provide clinical data about the management of elderly patients presenting complicated colorectal cancer who required emergency surgical management to improve their care.

METHODS

The management of complicated COlorectal cancer in OLDER patients (CO-OLDER; ClinicalTrials.gov ID: NCT05788224; evaluated by the local ethical committee CPP EST III-France with the national number 2023-A01094-41) in the emergency setting project provides carrying out an observational multicenter international cohort study aimed to collect data about patients aged ≥75 years to assess modifiable risk factors for negative outcomes and mortality correlated to the emergency surgical management of this group of patients at risk admitted with a complicated (obstructed and perforated) CRC. The CO-OLDER protocol was approved by Institutional Review Board and released. Each CO-OLDER collaborator is asked to enroll ≥25 patients over a study period from 1st January 2018 to 30th October 2023. Data will be analyzed comparing two periods of study: before and after the COVID-19 pandemic. A sample size of 240 prospectively enrolled patients with obstructed colorectal cancer in a 5-month period was calculated. The secured database for entering anonymized data will be available for the period necessary to achieve the highest possible participation.

RESULTS

One hundred eighty hospitals asked to be a CO-OLDER collaborator, with 36 potentially involved countries over the world.

CONCLUSIONS

The CO-OLDER project aims to improve the management of elderly people presenting with a complicated colorectal cancer in the emergency setting. Our observational global study can provide valuable data on the effectiveness of different management strategies in improving primary assessment, management and outcomes for elderly patients with obstructed or perforated colorectal cancer in the emergency setting, guiding clinical decision-making. This information can help healthcare providers make informed decisions about the best course of action for these patients.

Artificial intelligence in surgery

Artificial intelligence (AI) is rapidly emerging in healthcare, yet applications in surgery remain relatively nascent. Here we review the integration of AI in the field of surgery, centering our discussion on multifaceted improvements in surgical care in the preoperative, intraoperative and postoperative space. The emergence of foundation model architectures, wearable technologies and improving surgical data infrastructures is enabling rapid advances in AI interventions and utility. We discuss how maturing AI methods hold the potential to improve patient outcomes, facilitate surgical education and optimize surgical care. We review the current applications of deep learning approaches and outline a vision for future advances through multimodal foundation models.
