Introduction
Damage control surgery is based on temporal control of the injury, physiologic recovery and posterior deferred definitive management 1. This strategy has been traditionally performed in patients with severe abdominal and/or thoracic trauma 2,3. However, scenarios of hemodynamically unstable non-trauma patients with emergency pathologies treated with damage control surgery have been described but remain controversial in feasibility and safety 4-6. Therefore, this article aims to gather historical experiences in damage control surgery performed in non-traumatic abdominal emergency pathology patients with the presentation of a novel management algorithm.
This article is a consensus that synthesizes the experience earned during the past 30 years in trauma management, general surgery, and critical care acquired by the Trauma and Emergency Surgery (CTE) group from Cali, Colombia which is made up of experts from the Hospital Universitario del Valle "Evaristo García", the Hospital Universitario Fundación Valle del Lili, the Universidad del Valle and Universidad Icesi, and the collaboration of national and international specialists from the Asociación Colombiana de Cirugía and the Pan-American Trauma Society.
Historical evolution
Damage control in trauma: The basis of the lighthouse
In the 1980s, the debate began about the use of temporary strategies for managing abdominal catastrophes such as severe liver or splenic trauma 7-9. The first reports of abbreviated procedures showed reduced surgical time, lower postoperative complications, and higher survival rates 10. In 1993, Rotondo and Schwab, based on a series of 22 patients with abdominal vascular trauma who underwent abbreviated procedures, proposed Damage Control Surgery 11. This emerging evidence showing an increase in the survival rates of patients treated with damage control surgery triggered a surgical revolution 12.
However, with the implementation of damage control surgery, new challenges associated with the temporary management of the injury arose. The deferred management of cavities such as the abdomen raised how to treat the abdominal wall 13. A temporal closure strategy such as Bogotá bag (plastic covering of the cavity) was proposed 1. Nevertheless, some patients managed with this technique presented persistent hemodynamic instability due to Abdominal Compartment Syndrome, which is defined as an increase in intraabdominal pressure above 12 mmHg caused by intestinal edema secondary to mechanical abdominal organ contention. This represented a significant compromise in organ perfusion and ventilatory dynamics 14-16. Negative pressure wound therapy represented a solution to this challenge allowing a mechanical contention of the abdominal cavity, collection drainage, and injury hemostasis 3,17.
The concept of Damage Control Surgery was extended beyond the operating room to include prehospital settings, emergency room, intensive care units, and a multidisciplinary team to treat severely injured trauma patients 11. In 2007, Holcomb et al. proposed the concept of "Damage Control Resuscitation" that brings together damage control surgery with hemostatic resuscitation and permissive hypotension 18,19. Recently, endovascular strategies such as REBOA placement and angioembolization have been proposed as the fourth pillar for damage control resuscitation 20. This proposal is related to the new concept of "Endovascular Trauma Management-EVTM" which consists of the use of endovascular tools to treat severely injured trauma patients 21.
Damage control in non-traumatic abdominal emergencies: Building the lighthouse
The evolution of damage control surgery for non-traumatic abdominal emergencies is rather initiating. Life-threatening non-traumatic pathologies include generalized peritonitis, acute mesenteric ischemia, pancreatitis, necrotizing enterocolitis, and/or aortic dissection 22.
Two main pathophysiologic events that compromise the patient's life are a hemorrhagic and septic shock. Sepsis is an imbalance between anti-inflammatory and pro-inflammatory factors associated with an infectious process 23. Damage control surgery allows rapid control of abdominal contamination, avoiding major tissue injury and/or late interventions, which translates into an early resuscitation and physiological recovery 22.
In 2004, Finlay et al., performed the first study applying the principles of damage control surgery to non-traumatic pathology. They treated nine patients with intraabdominal sepsis secondary to hollow viscus perforation, three abdominal aortic aneurysms, one post-surgical hemorrhage, and one retroperitoneal hemorrhage with damage control surgery, showing a decrease in mortality compared with the predicted one 24. In the same year, Banieghbal et al. (24,performed a retrospective study in neonates with acute mesenteric ischemia who underwent damage control surgery. These interventions increase survival and reduce the need for ostomies and their complications.
Thus, damage control surgery has been proposed as an alternative in the emergency surgery scenario. Some considerations in damage control surgery in specific pathologies are discussed below.
Generalized peritonitis caused by gastrointestinal perforation
Abdominal sepsis causes a severe physiological compromise that represents a risk in anastomosis and anatomical reconstruction, with high anastomotic leak risk. Aggressive resuscitation, broad-spectrum antibiotics, and damage control surgery are the basis in abdominal contamination management in critically ill patients. Perathoner et al. presented an experience with 27 patients with acute perforated diverticulitis and peritonitis. Overall mortality was 26%. Patients undergoing anastomosis were 70%, with only one case of anastomosis dehiscence 25. These results have been similar to those reported in other studies in which clinical outcomes such as postoperative complication rates, type of device for abdominal wall closure, and resuscitation efforts have been included. Analyses adjusted for these confounding variables estimate the effect of damage control surgery in patients with acute diverticulitis 26-28.
Acute mesenteric ischemia
Acute mesenteric ischemia represents a surgical challenge due to its delayed diagnosis associated with greater hemodynamic compromise and a higher probability of death. Temporary control techniques of intestinal ischemia with endovascular approaches allow an abbreviated treatment with better clinical results. In 2009, Person et al. described a series of 31 patients who underwent damage control and of those, 10 had acute mesenteric ischemia. They reported higher mortality in the patients who underwent definite surgery. Nevertheless, hemodynamic compromise and multiorgan failure were greater in patients who underwent damage control surgery, representing a confusion factor 29. Also, Subramanian et al. performed a study in patients older than 65 years old treated with damage control surgery; 14 patients had intestinal ischemia and underwent damage control celiotomy. They concluded that age is not a predictor of adverse outcomes 30.
Duodenal bleeding or gastric ulcer
The general use of endoscopic approach and proton pump inhibitors has significantly reduced severe upper gastrointestinal bleeding. However, damage control surgery represents an alternative in cases where hemorrhagic control is not achieved despite these strategies. Khan et al. reported their experience with 42 patients undergoing damage control surgery with emergency non-traumatic abdominal pathology. Thirteen patients had gastrointestinal bleeding and complications such as intraabdominal collection and late abdominal sepsis. Additionally, they reported the effect of early abdominal wall closure after index surgery as a prognostic factor to avoid complications 31.
Complicated pancreatic surgery
The accidental injury of the portal system or retro-hepatic veins in pancreatic surgery is associated with higher mortality. A similar situation in necrotizing pancreatitis surgery could be presented where a vascular injury may be a life-threatening hemorrhage. Thus, damage control techniques for vascular lesions associated with pancreatic disease allow bleeding control and subsequent physiological recovery 32.
Damage Control Surgery for non-traumatic peritonitis: erecting the lighthouse light
The indications for damage control surgery in non-traumatized patients are a matter of debate. Evidence indicates that the application of damage control surgery in patients with no severe physiological compromise could be non-beneficial 22. Nevertheless, the impact of differed abdominal closure, surgical technique, intestinal repair type, and the comparison with conventional management is not defined. Our Trauma and Emergency Surgery group have studied these issues for the past 30 years in non-traumatic critically ill patients.
In 2006, Ordoñez and Puyana reported the first experience of the group describing the management of deferred intestinal repair by the following steps: contamination control, bowel in discontinuity, and delayed abdominal closure with negative pressure dressing 33. With this first experience, we evaluate the impact of abbreviated relaparotomy in patients with non-traumatic peritonitis, finding that it was not associated with higher mortality 34.
Then, the impact of the use of the intestinal reconstruction strategy through deferred anastomosis was evaluated. This intervention is an option in the management of this type of patient and avoids ostomies, improving postoperative quality of life 35.
In 2010, a detailed analysis of the advantages of patients managed with abbreviated anastomosis vs. abbreviated ostomy was conducted. There were no significant differences regarding mortality and morbidity among groups. Therefore deferred anastomosis is a safe strategy after the control of septic foci 36.
Management of damage control in non-traumatic abdominal pathology: turning on the light during the storm
Up to this point, a review has been made through the principles of damage control in trauma and the first experiences in non-traumatic pathologies. It is time to apply the principles of damage control for non-traumatic abdominal pathologies, which can lead to septic and hemorrhagic shock. This is the reason why damage control application phases must be recognized (Table 1)
Table 1 Damage Control Surgery in Non-traumatic Abdominal Pathology
| Septic Shock | Hemorrhagic Shock | |
|---|---|---|
| Phase 0 - Prehospital attention | Early diagnosis | Early Diagnosis |
| Vasopressor and intravenous fluids | Hemostatic resuscitation without delaying surgery | |
| Hypothermia correction | ||
| Early broad-spectrum antibiotic administration | ||
| Phase I | Identification of the source of infection and evaluation of the clinical state | Identification of bleeding source and evaluation of the clinical state |
| Phase II | Decontamination | Bleeding control |
| Infection source control | Differed abdominal wall closure | |
| Differed abdominal wall closure | ||
| Phase III | Intensive Care Unit resuscitation, acidosis, hypothermia, and coagulopathy correction | Intensive Care Unit physiologic resuscitation, acidosis, hypothermia, and coagulopathy correction. |
| Antibiotic management according to resistance profile. | ||
| Phase IV | Surgical reevaluation, definite repair, and abdominal wall closure | Surgical reevaluation, definite repair, and abdominal wall closure |
To meet these objectives and based on the experience over the last 15 years. In 2021, Ordoñez et al. published a comparative analysis of patients who underwent damage control surgery vs. definite surgery in the index surgery 37. Damage control surgery is not associated with higher mortality, hospital length of stay, hemodynamic support requirements, or complication rates. Furthermore, the most commonly used repair technique in 85% of patients who underwent damage control surgery was deferred anastomosis. Therefore, we propose the following algorithm that includes the principles of damage control surgery and deferred anastomosis as the main surgical strategy for intestinal reconstruction: (Figure 1).
Figure 1 Algorithm for the management of non-traumatic abdominal pathology applying the damage control surgery principles.
Phase 0: Crystalloid resuscitation and broad-spectrum antibiotics must be initiated associated with vasopressors if necessary. Diagnosis must be made by laboratory results and/or diagnostic tools. Preparation for surgery should begin with central catheter placement, invasive monitoring and blood components reserve.
Phase I: Drainage and lavage of the peritoneal cavity, with debridement and intestinal resection of the injured segment should be performed. If primary anastomosis is feasible, it should be performed, and the abdomen can be left opened or closed. Otherwise, if the anastomosis is not possible due to edema, hypoperfusion or hemodynamic instability, the surgeon should consider an ostomy with or without definite abdominal wall closure. However, Damage Control Surgery can be applied by leaving the bowel in discontinuity with a temporary ligation at the proximal and distal ends with an umbilical band or linear stapler with deferred closure of the abdomen by positioning a negative pressure dressing.
Phase II: The patient must be transferred to the Intensive Care Unit with hemodynamic support. Acidosis, hypothermia, and coagulopathy should be corrected. This phase should normally last between 24 and 48 hours, with a maximum of 72 hours.
Phase III: A second surgical approach must be made. If the coagulopathy, acidosis, hypothermia and intestinal edema resolve and adequate tissue perfusion is observed a hand-sewn or mechanical deferred anastomosis should be performed. If the patient does not meet these criteria and the surgeon considers that there is no other option, he or she may decide to perform definitive management with an ostomy. However, there may be a third scenario in which the intestinal ligatures could be released, the intestinal contents emptied, the bowel is left in discontinuity, a negative pressure dressing should be place and the patient should be transferred to the Intensive Care Unit for another 24 to 48 hours.
Phase IV: The clinical condition of the patient should be evaluated, and the definitive repair technique should be decided. If the clinical condition is favorable, a primary anastomosis must be preferred. Otherwise, an ostomy must be performed. In all cases, abdominal wall closure must be performed in the first seven days, either skin closure or skin and fascial closure. Moreover, abdominal wall reconstruction can be intended 8-12 months after closure.
Conclusion
The principles of damage control surgery can be applied in non-traumatic abdominal pathologies. This strategy is feasible and safe without increasing mortality or morbidity. Damage control is a light amid the storm for patients with metabolic decompensation due to abdominal sepsis or massive hemorrhage. It translates into a time window for a deferred intestinal reconstruction by anastomosis with better short- and long-term results.
