Intraoperative Surgical Strategy in Abdominal Emergency Surgery

Patients' Surgical History Profile and Its Association With Complexity in Major Emergency Abdominal Surgery

INTRODUCTION

Emergency abdominal surgery often involves patients with a surgical history. Previous abdominal surgery can complicate new procedures. The correlation between surgical history and complexity in major emergency surgery has not been assessed. The purpose of this study was to profile patients undergoing emergency abdominal surgery, regarding quantity and type of previous abdominal procedures and to assess their association with intraoperative complexity. We hypothesized that a history of abdominal surgery would be associated with increased intraoperative complexity, defined as a composite outcome of complicating factors and intraoperative events.

MATERIALS AND METHODS

We conducted an exploratory analysis of 754 consecutive patients undergoing major emergency abdominal surgery at a single institution. While multiple procedure- and patient-related variables were prospectively recorded in our local database, data on patient history and previous abdominal surgeries were collected retrospectively. Intraoperative iatrogenic lesions (unintended lesions to intra-abdominal organs), prolonged procedural time (≥3 h), or excessive intraoperative bleeding (≥1 L) were established as indicative of a complex procedure ('complexity factor'). Data were analyzed using multivariable logistic regression to identify significant preoperative risk factors for intraoperative complexity.

RESULTS

A total of 754 patients were included, with a median age of 71 y (interquartile range: 58-79), and 51% of the cohort were female. Among them, 476 patients (61%) had a history of previous abdominal surgery. In 192 (25%) of the procedures, surgeons reported at least one complexity factor. Previous colonic or rectal resection was associated with intraoperative complexity (2.34 risk ratio, confidence interval 95: 1.01-5.41, P = 0.05). Other significant factors were prior laparotomy, severe intra-abdominal adhesions, previous intra-abdominal abscess, and prior small bowel obstruction.

CONCLUSIONS

This study profiles emergency surgical patients with a history of abdominal surgery and explores the associations between previous surgery and complexity in subsequent procedures. Awareness of factors associated with increased procedural complexity is valuable to the surgical and anesthesiologic team in the planning of the procedure.

Associated peritoneostomy and pelvic ring fractures: prognostic factors in mortality and morbidity

BACKGROUND

High-energy polytrauma can be presented as an abdominal injury associated with a pelvic ring fracture. In the case of concomitant pelvic ring fracture peritoneostomy at admission, high morbidity and mortality rates could be expected.

OBJECTIVES

The main objective of this study is to assess prognostic factors that could contribute to the outcome of polytrauma patients who presented with pelvic ring fractures and were submitted to a peritoneostomy at admission. As a secondary aim, the functional outcome of the survivors was evaluated.

MATERIALS AND METHODS

A retrospective, cross-sectional, observational study was conducted. Polytrauma patients who were submitted to a peritoneostomy at admission due to high-energy abdominal injury and presented with concomitant pelvic ring fracture were included. Demographics data and prognostic factors related to "death" and infection were assessed. We applied the Majeed score for functional evaluation.

RESULTS

A total of 29 patients were included in the study. The mortality rate was 58.6% (n = 17). Considering only patients older than 45 years, the death rate was 90%. The variables with positive correlation to death were: (1) age > 45 years (p < 0.017) and (2) the absence of internal fixation (p < 0.011). Patients undergoing internal fixation had more infection rates (60%) compared to noninternal fixation group (11%) (p < 0.011). The average Majeed score was 54.7 points.

CONCLUSION

The predictive factors associated with increased mortality were age greater than 45 years and the absence of internal fixation. Concomitant pelvic ring fracture and peritoneostomy in admission implicate on high mortality and morbidity rates.

A high rate of mortality in liver cirrhosis patients after emergency abdominal surgery

PURPOSE

In the elective setting, there are high mortality rates for patients with liver cirrhosis after surgery. Few studies focus on emergency surgery. This study investigates mortality and morbidity of patients with cirrhosis undergoing emergency abdominal surgery.

METHODS

In a database established at two Copenhagen University Hospitals (Herlev and North Zealand), including all patients operated in an emergency setting (n = 1116), including all patients with known cirrhosis at time of surgery. Postoperative complications, and mortality rates were evaluated by a matched case-control method, matching cases and controls according to surgical procedure, age, sex and American Society of Anaesthesiologists-class (ASA). Medical and surgical complications were classified according to the Clavien-Dindo classification.

RESULTS

In the study, 24 patients with cirrhosis and 48 matched controls were evaluated. The 30-day mortality was 37.5% for patients with cirrhosis and 12.5% for controls (OR 4.2, 95% CI [1.28, 13.80], p = 0.014) and 90-day mortality was 62.5% for patients with cirrhosis compared to 18.8% for controls (OR 7.22, 95% CI [2.41, 21.68], p < 0.001). For patients with cirrhosis 58.3% had surgical complications compared to 31.3% for the controls (p = 0.027). The reoperation rate was 45.8% in the cirrhosis group and 22.9% in the control group (p = 0.047). The days-alive-out-of-hospital at 90-days (DAOH-90) was 9 days in the cirrhosis group and 78 days in the control group (p < 0.001).

CONCLUSION

This retrospective study shows that patients with cirrhosis have significantly higher mortality rates after emergency surgery, more surgical complications and reoperations, and reduced DAOH-90.

Short-term outcomes in mesh versus suture-only treatment of burst abdomen: a case-series from a university hospital

PURPOSE

Surgery for a burst abdomen after midline laparotomy is associated with later incisional hernia formation. Accommodating prophylactic measures, notably mesh augmentation, are of interest. However, data regarding safety and outcomes are scarce. This study aimed to evaluate the short-term risk profile of mesh prophylaxis in the context of a burst abdomen.

METHODS

This is a single-center prospective study of patients suffering from burst abdomen from 2021 to 2023. A treatment protocol for the management of burst abdomen was introduced, including the synthetic, partially absorbable onlay mesh. Adult patients (≥ 18 years) with a life expectancy of > 1 year with no plans of future pregnancies were recommended to be treated with a prophylactic mesh. In this analysis, adult patients were included if they suffered from a burst abdomen after elective or emergency laparotomy. The study evaluates short-term outcomes, including 90-day wound complications, length of stay, and mortality.

RESULTS

Sixty-seven patients fulfilled the inclusion criteria and underwent treatment for a burst abdomen during the study period. Thirty-eight patients were treated with a suture-only technique, and 29 patients were supplemented with a mesh. 13 of 14 observed wound complications in the mesh group were of mild degree (Clavien Dindo 1-3b), while one patient (3%) needed mesh-explantation. The 90-day mortality rate was 21% and comparable between suture-only and mesh techniques.

CONCLUSION

Mesh augmentation in surgery for a burst abdomen seems safe in well-selected patients at 90 days follow-up. Long-term data on the prophylactic effect on hernia development is needed.

The clinical consequences of burst abdomen after emergency midline laparotomy: a prospective, observational cohort study

PURPOSE

The emergency midline laparotomy is a commonly performed procedure with a burst abdomen being a critical surgical complication requiring further emergency surgery. This study aimed to investigate the clinical outcomes of patients with burst abdomen after emergency midline laparotomy.

METHODS

A single-center, prospective, observational cohort study of patients undergoing emergency midline laparotomy during a two-year period was done. Abdominal wall closure followed a standardized technique using monofilament, slowly absorbable suture in a continuous suturing technique with a suture-to-wound ratio of at least 4:1. Treatment of burst abdomen was surgical. Data, including intra-hospital postoperative complications, were collected and registered chronologically based on journal entries. The primary outcome was to describe postoperative complications, length of stay, and the overall morbidity based on the Comprehensive Complication Index (CCI), stratified between patients who did and did not suffer from a burst abdomen during admission.

RESULTS

A total of 543 patients were included in the final cohort, including 24 patients with burst abdomen during admission. The incidence of burst abdomen after emergency midline laparotomy was 4.4%. Patients with a burst abdomen had a higher total amount of complications per patient (median of 3, IQR 1.3-5.8 vs. median of 1, IQR 0.0-3.0; p = 0.001) and a significantly higher CCI (median of 53.0, IQR 40.3-94.8 vs. median of 21.0, IQR 0.0-42.0; p =  < 0.001).

CONCLUSION

Patients with burst abdomen had an increased risk of postoperative complications during admission as well as a longer and more complicated admission with multiple non-surgical complications.

Standardization of the strategy for open abdomen in nontrauma emergency laparotomy: A prospective study of outcomes in primary versus temporary abdominal closure

BACKGROUND

The indications for temporary abdominal closure in nontrauma surgery are heterogeneous and with limited data on clinical outcomes. This study aimed to report the outcomes of primary closure compared with temporary abdominal closure after nontrauma emergency laparotomy within a standardized clinical setting adapted from international guidelines.

METHODS

Included were all nontrauma patients undergoing emergency laparotomy between January 1, 2021, and December 31, 2022, at Copenhagen University Hospital Herlev in Denmark. All patients received treatment on the basis of standardized bundle of care trajectory for major emergency abdominal surgery. Mortality, risks of re-laparotomy, and postoperative complications were assessed using Kaplan-Meier plots and multiple logistic regression modeling.

RESULTS

Of the 576 included patients, temporary abdominal closure was performed in 57 (10%) patients in the initial surgery. Indications for temporary abdominal closure included damage control strategy as the result of considerable hemodynamic instability in 21 (37%) patients, need for reassessment of bowel viability in 21 (37%) patients, and loss of domain in 15 (25%) patients. Fascial closure was achieved after a median period of 2 days. Sixty-seven patients (12%) underwent re-laparotomy, with temporary abdominal closure performed in 10 (15%) of the cases. Patients with temporary abdominal closure had a significantly greater risk of postoperative complications (odds ratio 2.58, 95% confidence interval 1.38-4.89, P = .003). There were no significant differences in the risks of fascial dehiscence, re-laparotomy, or 30- or 90-days mortality.

CONCLUSION

Temporary abdominal closure was performed in 10% of patients undergoing nontrauma emergency laparotomy, with the primary indications being damage control strategy and need for reassessment of bowel viability. Patients undergoing temporary abdominal closure had a significantly greater risk of postoperative complications.

Impact of clinical frailty on surgical and non-surgical complications after major emergency abdominal surgery

BACKGROUND

Major emergency abdominal surgery is associated with a high risk of morbidity and mortality. Given the ageing and increasingly frail population, understanding the impact of frailty on complication patterns after surgery is crucial. The aim of this study was to evaluate the association between clinical frailty and organ-specific postoperative complications after major emergency abdominal surgery.

METHODS

A prospective cohort study including all patients undergoing major emergency abdominal surgery at Copenhagen University Hospital Herlev, Denmark, from 1 October 2020 to 1 August 2022, was performed. Clinical frailty scale scores were determined for all patients upon admission and patients were then analysed according to clinical frailty scale groups (scores of 1-3, 4-6, or 7-9). Postoperative complications were registered until discharge.

RESULTS

A total of 520 patients were identified. Patients with a low clinical frailty scale score (1-3) experienced fewer total complications (120 complications per 100 patients) compared with patients with clinical frailty scale scores of 4-6 (250 complications per 100 patients) and 7-9 (277 complications per 100 patients) (P < 0.001). A high clinical frailty scale score was associated with a high risk of pneumonia (P = 0.009), delirium (P < 0.001), atrial fibrillation (P = 0.020), and infectious complications in general (P < 0.001). Patients with severe frailty (clinical frailty scale score of 7-9) suffered from more surgical complications (P = 0.001) compared with the rest of the cohort. Severe frailty was associated with a high risk of 30-day mortality (33% for patients with a clinical frailty scale score of 7-9 versus 3.6% for patients with a clinical frailty scale score of 1-3, P < 0.001). In a multivariate analysis, an increasing degree of clinical frailty was found to be significantly associated with developing at least one complication.

CONCLUSION

Patients with frailty have a significantly increased risk of postoperative complications after major emergency abdominal surgery, especially atrial fibrillation, delirium, and pneumonia. Likewise, patients with frailty have an increased risk of mortality within 90 days. Thus, frailty is a significant predictor for adverse events after major emergency abdominal surgery and should be considered in all patients undergoing major emergency abdominal surgery.

Determining a multidisciplinary intraoperative strategy in emergency surgery for bowel obstruction and its impact on outcomes

PURPOSE

Bowel obstruction accounts for around 50% of all emergency laparotomies. A multidisciplinary (MDT) standardized intraoperative model was applied (definitive, palliative, or damage control surgery) to identify patients suitable for a one-step, definitive surgical procedure favoring anastomosis over stoma, when undergoing surgery for bowel obstruction. The objective was to present mortality according to the strategy applied and to compare the rate of laparoscopic interventions and stoma creations to a historic cohort in surgery for bowel obstruction.

METHODS

In a retrospective cohort study, we included patients undergoing emergency surgery for bowel obstruction during a 1-year period at two Copenhagen University Hospitals (2019 and 2021). The MDT model consisted of a 30- and 60-min time-out with variables such as functional and hemodynamic status, presence of malignancy, and surgical capabilities (lap/open). Pre-, intra-, and postoperative data were collected to investigate associations to postoperative complications and mortality. Stoma creation rates and laparoscopies were compared to a historic cohort (2009-2013).

RESULTS

Three hundred sixty-nine patients underwent surgery for bowel obstruction. Intraoperative surgical strategy was definitive in 77.0%, palliative in 22.5%, and damage control surgery in 0.5%. Thirty-day mortality was significantly lower in the definitive patient population (4.6%) compared to the palliative population (21.7%) (p < 0.000). Compared to the historic cohort, laparoscopic surgery for bowel obstruction increased from 5.0 to 26.4% during the 10-year time span, the rate of stoma placements was reduced from 12.0 to 6.1%, p 0.014, and the 30-day mortality decreased from 12.9 to 4.6%, p < 0.000.

CONCLUSION

An intraoperative improvement strategy can address the specific surgical interventions in patients undergoing surgery for bowel obstruction, favoring anastomosis over stoma whenever resection was needed, and help adjust specific postoperative interventions and care pathways in cases of palliative need.

Non-technical skills and teamwork in trauma: from the emergency department to the operating room

Management of a trauma patient is a challenging process. Swift and accurate clinical assessment is required and time-sensitive decisions and life-saving procedures must be performed in an unstable patient. This requires a coordinated response by both the emergency room (ER) and operating room (OR) teams. However, a team of experts does not necessarily make an expert team. Root cause analysis of adverse events in surgery has shown that failures in coordination, planning, task management and particularly communication are the main causes for medical errors. While most research is focused on the ER trauma team, the trauma OR team also deserves attention. In fact, OR team dynamics may resemble more the ER team than the elective OR team. ER and OR trauma teams assemble on short notice, and their members, who are from different specialties and backgrounds, may not train regularly together or even know each other beforehand. And yet, they have to perform high-risk procedures and make high stake decisions, in a time-sensitive manner. The airline industry has long recognized the role of team training and non-technical skills (NTS) in reducing hazards. The implementation of the so called crew resource management or crisis resource management (CRM) has significantly made airline travel safer and the transposition to the medical context, with specific training in non-technical skills, has also brought great benefits. In fact, it is clear that adoption of non-technical skills (NTS) in healthcare has led to an increase in patient safety. In this narrative review we recapitulate some of the key non-technical skills and their relevance in trauma, with a focus on both the emergency department (ER) and the operating room (OR) teams, as well as on the transition of care from one to the other. Also, we explore the use of debriefing the team, as well as the roles of NTS training in both undergraduate and postgraduate settings. We review some of the existing trauma training courses and their roles in developing NTS. Finally, we briefly address the challenges posed by the development of trauma hybrid operating rooms.

Surgical Emergencies in Patients with Significant Comorbid Diseases

Emergency surgery in patients with significant comorbidities benefits from a structured approach to preoperative evaluation, intra-operative intervention, and postoperative management. Providing goal concordant care is ideal using shared decision-making. When operation cannot achieve the patient's goal, non-operative therapy including Comfort Care is appropriate. When surgical therapy is offered, preoperative physiology-improving interventions are far fewer than in other phases. Reevaluation of clinical care progress helps define trajectory and inform goals of care. Palliative Care Medicine may be critical in supporting loved ones during a patient's critical illness. Outcome evaluation defines successful strategies and outline opportunities for improvement.
