Damage control surgery in neonates: Lessons learned from the battlefield

INTRODUCTION

Mortality for neonates requiring surgery for serious pathology such as NEC, remains high. Damage control surgery (DCS) has evolved as an operative strategy in battlefield trauma that sacrifices the completeness of the initial surgery to address the deadly triad of acidosis, hypothermia and coagulopathy. This approach is now used routinely in sick adults with nontrauma surgical emergencies. Here we describe our experience of using DCS in neonates.

METHOD

Neonates undergoing DCS at our hospital from 1/8/2010 to 30/11/17 had data collected prospectively.

RESULTS

27 neonates (median age 21 days; gestation 29 weeks; weight 1200 g; M:F 18:9) underwent DCS. Diagnosis (NEC 23, volvulus 2, meconium peritonitis 1, spontaneous perforation 1). Preoperative physiology: median temperature 35.5 °C, lactate 3.7, Activated prothrombin time 49; on a median of 1 inotrope (range 0 to 4); 19 had surgery on the intensive care unit. Surgery involved resection of dead bowel with the ends ligated and the abdomen left open. Operation took 38 min (26-80 min) and crew-resource management techniques were used to optimize efficiency. Second look occurred at 48 h (24-108 h) when the physiology had normalized. There were a total of 32 anastomoses in 18 patients with one leak; 3 patients had stomas for distal rectal disease. Overall mortality was 15% (4/27) or 18% in the NEC group (4/23).

CONCLUSION

Though techniques such as "clip and drop" exist, they have not been routinely incorporated into an operative strategy for sick neonates based on physiological derangement. The two benefits from our DCS approach were a low mortality and an avoidance of stomas. This approach deserves more investigation to see whether it is as effective in babies and children with nontrauma associated abdominal catastrophes as it is in adults.

[The TraumaRegister DGU® dataset, its development over 25 years and advances in the care of severely injured patients]

BACKGROUND

Since the publication in 1993, the dataset and documentation form of the TraumaRegister DGU® (TR-DGU) have continuously evolved. On the occasion of the 25th anniversary the authors have analyzed this evolution in order to reflect it in the light of medical progress in the treatment of the severely injured.

MATERIAL AND METHODS

Enrolled in the study were 5 reference data entry sheets from the years 1993, 1996, 2002, 2009 and 2016. Every piece of information (item) queried therein was entered into the study database, was categorized by topic and counted for further analysis.

RESULTS

The arrangement of the 4‑page data entry form has remained practically unchanged since 1993 and includes an average of 212 items. A total of 491 items were identified of which 64 were present throughout every dataset. Based on the average extent of the form this equals a proportion of approximately 30%. The dataset actually shows much more consistency than this number suggests because many changes can be traced back to a smarter design of the data entry form. Most items fell into the categories "results/diagnosis" (143 items/29.1%), "coagulation" (104/21.2%) and "surgical approach" (40/8.1%). Many items serve as raw data for the calculation of prognostic risk scores, such as the trauma and injury severity score (TRISS), the revised injury severity classification II (RISC II) and the trauma associated severe hemorrhage (TASH) score. Currently, nine scores can be calculated from the dataset.

CONCLUSION

The members of the working group TraumaRegister all actively participate in the treatment of severely injured patients. For 25 years this group has managed to unify the latest medical developments and well-established parameters within the TR-DGU dataset at a relatively constant degree of effort for documentation. Practice in place of theory is the driving force behind this development that serves quality assurance and research in the treatment of severely injured patients.

[The therapeutic experience of blunt pancreatic trauma]

Objective: To summarize the experience of treatment for blunt pancreatic trauma. Methods: The clinical data of 52 patients with blunt pancreatic trauma admitted to the Department of Pancreatic and Biliary Surgery of the First Affiliated Hospital of Harbin Medical University from January 2013 to June 2018 were analyzed retrospectively.There were 40 male and 12 female patients, aging from 12 to 112 years with a median age of 35.5 years.According to the organ injury scale by American Association for the Surgery of Trauma(AAST) for pancreatic injury severity, 15 cases were in grade Ⅰ(28.8%), 20 cases were in grade Ⅱ(38.5%), 10 cases were in grade Ⅲ(19.2%),5 cases were in grade Ⅳ(9.6%) and 2 cases were in grade Ⅴ(3.8%). Isolated blunt pancreatic trauma occurred in 11(21.2%) patients including 5 cases of grade Ⅰ,5 cases of grade Ⅱ and 1 case of grade Ⅲ, and associated injuries existed in 41 patients(78.8%). Results: Among 52 patients, 36 patients(69.2%) were transferred from other hospitals and 16(30.8%) patients were admitted through the emergency department. Finally, 49 patients(94.2%) were cured and 3 patients (5.8%) died.For the 15 cases of grade Ⅰ,9 patients were managed non-operatively, 5 cases underwent peritoneal lavage and drainage after surgery for the other injured abdominal organs, and 1 patient received percutaneous catheter drainage(PCD) with non-operative treatment. For the 20 cases of grade Ⅱ,4 cases only received non-operative treatment and 2 cases also received PCD. Besides, 2 cases underwent debridement and drainage for peripancreatic necrotic tissue and external drainage for pancreatic pseudocyst retrospectively after about 25 days of getting injured. As for patients who received exploratory laparotomy, 5 patients underwent suture repair associated with external drainage, and 7 patients were managed only with external drainage. For the 10 cases of grade Ⅲ,6 patients were cured through distal pancreatectomy and splenectomy with external drainage, while 2 patients underwent endoscopic retrograde cholangiopancreatography and ductal stenting, and the other 2 patients just received debridement and drainage for peripancreatic necrotic tissue.For the 5 cases of grade Ⅳ,2 patients underwent jejunostomy and abdominal cavity drainage, 1 patient had a pancreaticoduodenectomy with drainage,1 patient received suture repair of the pancreas and pancreaticojejunostomy, and 1 patient was managed with suture repair of the head of pancreas and external drainage.For the 2 patients of grade Ⅴ,1 patient received exploratory laparotomy and gauze compression packing hemostasis, and the other patient underwent pancreaticoduodenal repair, gastrointestinal anastomosis, duodenal exclusion surgery and external drainage. Conclusion: According to the AAST classifications, associated injuries, physiological status and intraoperative situation, it could be better to make a comprehensive judgment, achieve early diagnosis and take appropriate individualized treatment strategy, and to improve the overall therapeutic effect for blunt pancreatic trauma.

Damage control surgery for unstable thoracic wall injury

Damage control surgery (DCS) consists of three steps: an abbreviated initial operation, resuscitation in the ICU, and a planned reoperation. Although DCS for lung and heart injury have been established, there is no concept of DCS for the chest wall. We experienced a successful case, in which a DCS of chest wall lifting procedure and internal pneumatic stabilization were performed on the flail chest accompanied by a remarkable destruction of chest wall. As a result, the patient's abnormal breathing improved. Surgical fixations using KANI plate were performed at a later date. We suggest that the chest wall lifting procedure may be suitable as a DCS for thoracic cage destruction from severe chest wall injury.

Damage control surgery for perforated diverticulitis with diffuse peritonitis: saves lives and reduces ostomy

Introduction

Over the last decade, damage control surgery (DCS) has been emerging as a feasible alternative for the management of patients with abdominal infection and sepsis. So far, there is no consensus about the role of DCS for acute perforated diverticulitis. In this study, we present the outcome of a multi-institutional series of patients presenting with Hinchey's grade III and IV diverticulitis managed by DCS.

Methods

All the participating centers were tertiary referral hospitals. A total of 34 patients with perforated diverticulitis treated with DCS during the period 2011–2017 were included in the study. During the first laparotomy, a limited resection of the diseased segment was performed followed by lavage and use of negative pressure wound therapy (NPWT). After 24/48 h of resuscitation, patients returned to the operating room for a second look. Mortality, morbidity, and restoration of bowel continuity were the primary outcomes of the study.

Results

There were 15 males (44%) and 19 females (56%) with a mean age of 66.9 years (SD ± 12.7). Mean BMI was 28.42 kg/m² (SD ± 3.33). Thirteen cases (38%) were Wasvary’s modified Hinchey's stage III, and 21 cases (62%) Hinchey's stage IV. Mean Mannheim Peritonitis Index (MPI) was 25.12 (SD ± 6.28). In 22 patients (65%), ASA score was ≥ grade III. Twenty-four patients (71%) had restoration of bowel continuity, while 10 (29%) patients had an end colostomy (Hartmann’s procedure). Three of these patients received a temporary loop ileostomy. One patient had an anastomotic leak. Mortality rate was 12%. Mean length of hospital stay was 21.9 days. At multivariate analysis, male gender (p = 0.010) and MPI (p = 0.034) correlated with a high percentage of Hartmann’s procedures.

Conclusion

DCS is a feasible procedure for patients with generalized peritonitis secondary to perforated diverticulitis, and it appears to be related to a higher rate of bowel reconstruction. Due to the open abdomen, stay in ICU with prolonged mechanical ventilation is required, but these aggressive measures may be needed by most patients undergoing surgery for perforated diverticulitis, whatever the procedure is done.

[Management of traumatic intestinal injury of mass casualties]

While intestinal injury is relatively rare in blunt abdominal trauma, it is common in penetrating abdominal trauma. Intestinal injury cannot be detected effectively by computed tomography (CT); therefore penetrating abdominal injury or abdominal signs in blunt trauma require liberal indications for explorative laparotomy. In mass casualty situations patients with hemodynamic instability and abdominal signs should be prioritized for surgery. Besides intra-abdominal hemorrhage the major issue is septic complications due to intestinal perforation. The current surgical strategy should reflect the number of injured patients and the individual pattern of injuries. Damage control surgery is not an effective strategy to improve survival rates in severely injured patients or in mass casualty situations. Damage control surgery focuses on lifesaving procedures especially bleeding control and control of contamination. This includes an open abdomen strategy with later definitive repair and abdominal wall closure.

Open abdominal management for perforative peritonitis with septic shock: a retrospective analysis on usefulness of a standardized treatment protocol

BACKGROUND

Damage control surgery (DCS) with open abdominal management (OAM) has been increasingly expanded to include critically ill non-trauma patients. However, there is limited data regarding the usefulness of this protocol for the treatment of severe perforative peritonitis (PP), especially with septic shock (SS). Here, we retrospectively evaluated the usefulness of our OAM protocol for PP with SS.

METHODS

We retrospectively reviewed patients with from June 2015 to September 2018. The proposed protocol was composed of the following steps: (1) rapid control of contamination; (2) temporary abdominal closure; (3) repeated washout of the abdominal cavity; and (4) delayed definitive surgery. For temporary abdominal closure, a negative pressure wound therapy device was used. The end points were the morbidity and 30-day mortality rates. Logistic backward regression was performed to identify factors associated with complications.

RESULTS

The mortality rate was 4% (1/25) and the overall morbidity rate of surviving patients was 58.3% (14/24). The mean duration of the first DCS was 67.36 ± 22.83 min. The median durations of ventilation and intensive care unit stay were 5 and 7 days, respectively. Although not significant, morbidity might be associated with age, diabetes mellitus, initial operative time, and OAM duration.

CONCLUSIONS

A standardized protocol for OAM may improve the outcomes of patients with SS due to PP. This damage control approach can be applied for the treatment of severe abdominal sepsis.

Primary repair of duodenal injuries: a retrospective cohort study from a major trauma centre in South Africa

BACKGROUND AND AIMS

The management of duodenal trauma remains controversial. This retrospective audit of a prospectively maintained database was intended to clarify the operative management of duodenal injury at our institution and to assess the risk factors for leak following primary duodenal repair.

MATERIALS AND METHODS

This was a retrospective study undertaken at the Pietermaritzburg Metropolitan Trauma Service, Pietermaritzburg, South Africa. Operative techniques used for duodenal repair were recorded. Our primary outcome was duodenal leak in the postoperative period. Patients from January 2012 to December 2016 were included. All duodenal injuries were graded according to the American Association for the Surgery of Trauma (AAST) grading. Only patients who had a primary repair were included in the final analysis.

RESULTS

During the five-year data collection period, a total of 562 patients underwent a trauma laparotomy; of which 94 patients sustained a duodenal injury. A primary pyloric exclusion and gastro-jejunostomy (PEG) was performed in three patients. These three were then excluded from further analysis. Of the 91 primary duodenal repairs, seven (8%) subsequently leaked. These were managed by PEG in three and by secondary repair and para-duodenal drainage in four. The two physiological parameters most associated with subsequent leak were lactate and pH level. There was a significantly higher mortality rate for those who leaked vs those who did not leak. Chi-squared test revealed a significant difference in the leak rate between AAST I (0%), AAST-II (1.6%) and AAST-3 (66.7%) grade injuries (p <0.01).

CONCLUSION

The trend towards primary repair of duodenal injuries appears to be justified. However duodenal leak remains a significant risk in certain high risk patients and strategies to manage injuries in this subset requires further work.

Dutch combat operation experiences in Iraq and Afghanistan: The conundrum of low surgical workload deployments

INTRODUCTION

The Combined Joined Task Force - Operation Inherent Resolve is the military intervention of Iraq and Coalition Forces in the battle against Islamic State of Iraq and Syria (ISIS). Al Assad Airbase (AAAB) is one of the key airbases. It contains a Role 2 Medical Treatment Facility, primarily to perform Damage Control Surgery in Coalition Forces, Iraqi National Security Forces and Local Nationals. We present a six month medical exposure in order to provide insight into the treatment of casualties and to optimize medical planning of combat operations and (pre-/post-) deployment training.

PATIENTS AND METHODS

This is a cohort study of casualties that were admitted to the Role 2 Medical Treatment Facility AAAB from November 2017 to April 2018. Their mechanisms and types of injury are described and compared to those sustained in Uruzgan, Afghanistan between 2006-2010. Additionally, they are compared to the caseload in the Dutch civilian medical centers of the medical specialist team at AAAB.

RESULTS

There were significant differences in both mechanism and type of injury between Coalition Forces and Iraqi Security Forces (p = 0.0001). Coalition Forces had 100% disease and non-battle injuries, where Iraqi Security Forces had 86% battle injuries and 14% non-battle casualties. The most common surgical procedures performed were debridement of wounds (38%), (exploratory) laparotomy (10%) and genital procedures (7%). The surgical caseload in Uruzgan, Afghanistan was significantly different in aspect and quantity, being 4.1 times higher. When compared to the workload at home all team members had at least a tenfold lower workload than in their civilian hospitals.

DISCUSSION

The deployed surgical teams were scarcely exposed to casualties at AAAB, Iraq. These low workload deployments could cause a decline in surgical skills. Military medical planning should be tailormade and should include adjusting length of stay, (pre-/post-)deployment refresher training and early consultation of military medical specialists. Future research should focus on optimizing this process by investigating fellowships in combat matching trauma centers, regional and international collaboration and refresher training possibilities to maintain the expertise of the acute military care provider.

The evolution and impact of the "damage control orthopedics" paradigm in combat surgery: a review

The idea of damage control (DC) is grounded on a sequential therapeutic strategy that supports physiological restoration over anatomic repair in critically injured patients. This concept is firstly described as damage control surgery (DCS) for war-wounded patients with abdominal exsanguinating trauma. The goal was to avoid prolonged operative times and prevent the outset of the lethal cycle of hypothermia, acidosis and coagulopathy. Damage control orthopedics (DCO) is also based on this concept and it is applied in the treatment of some polytrauma patients with pelvic and long bones fractures as to avoid the "second hit" of a lengthy definitive operation and eliminate initial morbidity and mortality. It is in favor of primary fracture stabilization utilizing provisional external fixation. When the patient is in stable condition, conversion to definitive open reduction and intramedullary nailing can be done. This stepwise approach should be considered as a part of the resuscitation process, and it follows the saying "do no further harm".

Impact of initial temporary abdominal closure in damage control surgery: a retrospective analysis

Background

Damage control surgery has revolutionized trauma surgery. Use of damage control surgery allows for resuscitation and reversal of coagulopathy at the risk of loss of abdominal domain and intra-abdominal complications. Temporary abdominal closure is possible with multiple techniques, the choice of which may affect ability to achieve primary fascial closure and further complication.

Methods

A retrospective analysis of all trauma patients requiring damage control laparotomy upon admission to an ACS-verified level one trauma center from 2011 to 2016 was performed. Demographic and clinical data including ability and time to attain primary fascial closure, as well as complication rates, were recorded. The primary outcome measure was ability to achieve primary fascial closure during initial hospitalization.

Results

Two hundred and thirty-nine patients met criteria for inclusion. Primary skin closure (57.7%), ABThera™ VAC system (ABT) (15.1%), Bogota bag (BB) (25.1%), or a modified Barker's vacuum-packing (BVP) (2.1%) were used in the initial laparotomy. Patients receiving skin-only closure had significantly higher rates of primary fascial closure and lower hospital mortality, but also significantly lower mean lactate, base deficit, and requirement for massive transfusion. Between ABT or BB, use of ABT was associated with increased rates of fascial closure. Multivariate regression revealed primary skin closure to be significantly associated with primary fascial closure while BB was associated with failure to achieve fascial closure.

Conclusions

Primary skin closure is a viable option in the initial management of the open abdomen, although these patients demonstrated less injury burden in our study. Use of vacuum-assisted dressings continues to be the preferred method for temporary abdominal closure in damage control surgery for trauma.

Use of an intravascular temperature control catheter for rewarming of hypothermic trauma patients with ongoing hemorrhagic shock after combined damage control thoracotomy and laparotomy: A case series

BACKGROUND

Correction of hypothermia is a key component of the resuscitation of critically injured patients with hemorrhagic shock who require damage control surgery. External rewarming methods may not be sufficient in this population, while extracorporeal techniques lack widespread feasibility. Intravascular catheter-based temperature modulation is increasingly being employed in different critically ill patient populations but has not been described as part of a damage control resuscitation strategy in trauma patients.

METHODS

We retrospectively reviewed the medical records of all patients admitted to our multi-trauma intensive care unit from July 1, 2015 - December 31, 2017 in whom an intravascular temperature control catheter (IVTCC) was employed for rewarming from hypothermia during the immediate postoperative resuscitation of continued hemorrhage after undergoing combined damage control thoracotomy and laparotomy for trauma. All patients received baseline treatment with active external rewarming modalities and inline fluid/blood warmers. Core temperature values over the first 24 h of hospital admission were analyzed. Efficacy (rewarming rate) and safety (associated adverse events) of the IVTCC system were determined.

RESULTS

Three patients (age 22 ± 4.6, 100% male, 100% torso gunshot wounds with prehospital cardiac arrest) meeting the inclusion criteria were treated with the IVTCC system during the study period. Temperature at the start of rewarming using the IVTCC ranged from 30.1 to 35.5 °C. Despite ongoing severe hemorrhagic shock (24-hour ICU blood product requirement: 104 ± 44 units), a mean rewarming rate of 1.04 ± 0.63°C/hour was achieved. One patient suffered an uncomplicated catheter-associated deep vein thrombosis. Two of the 3 patients survived to hospital discharge with intact cognitive function.

CONCLUSIONS

Use of an IVTCC may be a minimally-invasive, practical, and effective method for rewarming critically ill trauma patients with ongoing hemorrhagic shock after multi-cavitary damage control surgery. Further studies are needed to compare this technology with currently available rewarming methods.

Damage control surgery in perforated diverticulitis: ongoing peritonitis at second surgery predicts a worse outcome

PURPOSE

Damage control strategy (DCS) is a two-staged procedure for the treatment of perforated diverticular disease complicated by generalized peritonitis. The aim of this retrospective multicenter cohort study was to evaluate the prognostic impact of an ongoing peritonitis at the time of second surgery.

METHODS

Consecutive patients who underwent DCS for perforated diverticular disease of the sigmoid colon with generalized peritonitis at four surgical centers were included. Damage control strategy is a two-stage emergency procedure: limited resection of the diseased colonic segment, closure of oral and aboral colon, and application of a negative pressure assisted abdominal closure system at the initial surgery followed by second laparotomy 48 h later. Therein, decision for definite reconstruction (anastomosis or Hartmann's procedure (HP)) is made. An ongoing peritonitis at second surgery was defined as presence of visible fibrinous, purulent, or fecal peritoneal fluid. Microbiologic findings from peritoneal smear at first surgery were collected and analyzed.

RESULTS

Between 5/2011 and 7/2017, 74 patients underwent a DCS for perforated diverticular disease complicated by generalized peritonitis (female: 40, male: 34). At second surgery, 55% presented with ongoing peritonitis (OP). Patients with OP had higher rate of organ failure (32 vs. 9%, p = 0.024), higher Mannheim Peritonitis Index (25.2 vs. 18.9; p = 0.001), and increased operation time (105 vs. 84 min., p = 0.008) at first surgery. An anastomosis was constructed in all patients with no OP (nOP) at second surgery as opposed to 71% in the OP group (p < 0.001). Complication rate (44 vs. 24%, p = 0.092), mortality (12 vs. 0%, p = 0.061), overall number of surgeries (3.4 vs. 2.4, p = 0.017), enterostomy rate (76 vs. 36%, p = 0.001), and length of hospital stay (25 vs. 18.8 days, p = 0.03) were all increased in OP group. OP at second surgery occurred significantly more often in patients with Enterococcus infection (81 vs. 44%, p = 0.005) and with fungal infection (100 vs. 49%, p = 0.007). In a multivariate analysis, Enterococcus infection was associated with increased morbidity (67 vs. 21%, p < 0.001), enterostomy rate (81 vs. 48%, p = 0.017), and anastomotic leakage (29 vs. 6%, p = 0.042), whereas fungal peritonitis was associated with an increased mortality (43 vs. 4%, p = 0.014).

CONCLUSION

Ongoing peritonitis after DCS is a predictor of a worse outcome in patients with perforated diverticulitis. Enterococcal and fungal infections have a negative impact on occurrence of OP and overall outcome.

Outcome and complications after treatment of facial fractures at different times in polytrauma patients

Finding the correct point of time for operative treatment of facial fractures in multiply injured people remains one of the most important challenges in modern emergency medicine. Findings relating to pathophysiological mechanisms after severe trauma argue against the early operative treatment of non-life-threatening injuries. Our retrospective analysis investigated the effects on complications and outcome of different time points for operative treatment of maxillofacial fractures in multiply injured patients. Over a period of 10 years (2003-2012) we could identify 1543 patients, of whom 553 had fractures of the facial skull. 168 of the facial fracture patients were operated on their fractures, 97 at a time later than 72 h. Despite the delayed time of operation, the patients showed fewer complications (21.6% vs 25.4%). This resulted in fewer additional stays in hospital (9.3% vs 11.3%), and also in fewer plate removals (23.7% vs 33.8%). We conclude that delayed operative fracture treatment does not lead to more complications. The optimal time for operative treatment has to be determined individually as the earliest point at which no adverse effects from comorbidities are expected.

Management specificities for abdominal, pelvic and vascular penetrating trauma

Management of patients with penetrating trauma of the abdomen, pelvis and their surrounding compartments as well as vascular injuries depends on the patient's hemodynamic status. Multiple associated lesions are the rule. Their severity is directly correlated with initial bleeding, the risk of secondary sepsis, and lastly to sequelae. In patients who are hemodynamically unstable, the goal of management is to rapidly obtain hemostasis. This mandates initial laparotomy for abdominal wounds, extra-peritoneal packing (EPP) and resuscitative endovascular balloon occlusion of the aorta (REBOA) in the emergency room for pelvic wounds, insertion of temporary vascular shunts (TVS) for proximal limb injuries, ligation for distal vascular injuries, and control of exteriorized extremity bleeding with a tourniquet, compressive or hemostatic dressings for bleeding at the junction or borderline between two compartments, as appropriate. Once hemodynamic stability is achieved, preoperative imaging allow more precise diagnosis, particularly for retroperitoneal or thoraco-abdominal injuries that are difficult to explore surgically. The surgical incisions need to be large, in principle, and enlarged as needed, allowing application of damage control principles.

Methods of hemostasis in abdominal surgery

Hemorrhage is one of the common concomitant conditions during abdominal surgeries, and it is also the main cause of non-planed secondary surgery. There are various methods for abdominal surgical hemostasis. How to adopt reasonable methods to manage intraoperative bleeding promptly and effectively has bothered surgeons for a long time. With the development of minimally invasive technology and surgical instruments, laparoscopy and more hemostasis techniques have been widely used during abdominal surgery. This article summarizes the methods of hemostasis during abdominal surgery.

Thyrohyoid membrane transection caused by a stab injury

Background

The thyrohyoid membrane is located between the hyoid bone and thyroid cartilage. Transection of the thyrohyoid membrane can be fatal.

Case presentation

A 54-year-old man presented to the emergency room after attempting to commit suicide by cutting his neck. An endotracheal tube was inserted through the thyrohyoid membrane, which had been cut almost completely. After a tracheostomy, temporary wound closure was performed due to coagulopathy caused by hemorrhagic shock. Several hours later, a hyoidothyroidopexy was performed. Damage control surgery was applied to this patient's neck injury. The tracheostomy tube was removed postoperatively and he was discharged without complications.

Conclusion

Damage control surgery could be an option for airway injury with blood clotting problems due to massive bleeding after securing a patent airway.

Damage control: Concept and implementation

The concept of damage control (DC) is based on a sequential therapeutic strategy that favors physiological restoration over anatomical repair in patients presenting acutely with hemorrhagic trauma. Initially described as damage control surgery (DCS) for war-wounded patients with abdominal penetrating hemorrhagic trauma, this concept is articulated in three steps: surgical control of lesions (hemostasis, sealing of intestinal spillage), physiological restoration, then surgery for definitive repair. This concept was quickly adapted for intensive care management under the name damage control resuscitation (DCR), which refers to the modalities of hospital resuscitation carried out in patients suffering from traumatic hemorrhagic shock within the context of DCS. It is based mainly on specific hemodynamic resuscitation targets associated with early and aggressive hemostasis aimed at prevention or correction of the lethal triad of hypothermia, acidosis and coagulation disorders. Concomitant integration of resuscitation and surgery from the moment of admission has led to the concept of an integrated DCR-DCS approach, which enables initiation of hemostatic resuscitation upon arrival of the injured person, improving the patient's physiological status during surgery without delaying surgery. This concept of DC is constantly evolving; it stresses management of the injured person as early as possible, in order to initiate hemorrhage control and hemostatic resuscitation as soon as possible, evolving into a concept of remote DCR (RDCR), and also extended to diagnostic and therapeutic radiological management under the name of radiological DC (DCRad). DCS is applied only to the most seriously traumatized patients, or in situations of massive influx of injured persons, as its universal application could lead to a significant and unnecessary excess-morbidity to injured patients who could and should undergo definitive treatment from the outset. DCS, when correctly applied, significantly improves the survival rate of war-wounded.

Outcome evaluation of staged treatment for bicondylar tibial plateau fractures

BACKGROUND

The universal accepted strategy for treating high-energy tibial plateau fractures remains a topic of ongoing debate. The challenge for the practicing orthopaedic trauma surgeon is to provide anatomical articular fracture reduction, with successfully managing the complex soft-tissue injury that is commonly present at patient admission. The primary aim of the actual study was to evaluate the results of a staged protocol for the treatment of high-energy bicondylar tibial plateau fractures. The secondary aim was to describe the technique used for the definitive fixation of this complex fracture pattern.

METHODS

Thirty patients with unstable high-energy closed bicondylar tibial plateau fractures (17 Schatzker V and 13 Schatzker VI) were managed. There were 24 men (80%) and six women (20%). All of them were skeletally mature with their age ranging from 19 to 67 years (mean of 33.1±3.4 years). Treatment involved a two-stage procedure with appropriate emergency care, preoperative planning, and definitive fixation. Initial treatment, named 'damage control on complex articular fracture elements', consisted on temporary bridging external fixation. Definitive treatment was delayed in a mean of 10 days (ranging from seven to 13 days) and was performed when the soft-tissue conditioning demonstrated either complete or almost complete remission of the inflammatory reaction due to the 'first hit'. Conventional implants were used in the 30 patients. All patients were evaluated clinically and radiographically.

RESULTS

Twenty-six (86.7%) patients had a moderate level of activity, three (10%) patients had a very light level of activity, and one (3.3%) patient was unable to have any kind of work activity and is currently supported by the Brazilian Welfare. Using the visual analog scale mean pain score was 30 (ranging from 10 to 60); even the patient with the workers' compensation had no severe pain. All patients except three have no difficulty with stairs, giving way, locking, swelling, and squatting, but were unable to run. Three (10%) patients had problems with stairs and could not bend the operated knee more than 90^°. One of them had a varus knee but no instability. Ninety percent of the patients were either very satisfied or somewhat satisfied with their outcome. The three dissatisfied patients suffered postoperative complications, most commonly wound infections. Four (13.4%) patients with former anatomical reduction had a residual articular step-off or diastasis of less than 3mm after fracture healing. All patients had no or mild arthrosis at the time of the last outpatient consultation.

CONCLUSIONS

The two-staged procedure presented herein showed to be an effective strategy for managing bycondilar tibial plateau fractures. The protocol used for these complex traumatic injuries follows very well defined steps, which means acute stabilization with a linear bridging external fixation, adequate soft tissue handling, preoperative planning, and definitive surgical fixation after seven to 14 days. The model presents a more biological approach to optimizing functional outcome with an acceptable complication rate and minimal risk of loss of reduction in these high-energy tibial plateau fractures.

Damage control surgery - experiences from a level I trauma center

Background

There is still no evidence in literature for damage control orthopaedics (DCO), early total care (ETC) or using external fixation solely in fractures of the long bones in multi-system-trauma. The aim of this study was to determine parameters influencing the choice of treatment in clinical routine (DCO, ETC, or EF) in femoral or tibial shaft fractures in combination with multi-system-trauma, severe soft tissue damage or both.

Methods

Data of 236 patients with 280 fractures of long bones of the lower extremities treated at a level I trauma center were analysed. Clinical parameters on arrival (age, sex [m/f], ISS, fracture site [femur/tibia], soft tissue damage [closed or open fractures according to the Gustilo-Anderson classification], pulmonary injury [yes/no]) were collected and analysed whether they influence the choice of upcoming treatment (DCO/ETC/EF).

Results

Our findings showed that high ISS and severe soft tissue damage (grade III) significantly correlated with DCO. High ISS, old age, female sex and fracture site (tibia) correlated with EF. This group of sole use of external fixation had highest rate of complications, 69% were associated with at least one complication.

Conclusion

Severely injured patients are treated significantly more often with DCO or EF. The presence of higher ISS (≥16) and of type III open fractures increased the use of DCO. However, ISS, fracture-site, patient’s age, type III open fractures or sex (female) increased the use of EF compared to ETC.

Combat surgery: Status of tactical abbreviated surgical control

Traditionally injury care meant definitive repair following surgical exploration. However the outcome is poor because of deranged physiology in severely injured. Damage control surgery (DCS) is abbreviated initial procedure with subsequent correction of physiological imbalance, followed by definite repair. Tactical abbreviated surgical control (TASC) is application of principles of DCS techniques in the tactical environment. TASC is applied because of patient related factors (classic damage control) and limitations due to tactical reasons. Non-patient related factors only seen in tactical setting are, large numbers of patients arriving in short span, mobility of forward medical units, limitation of resources, and hostile environment. TASC involves only phase one of classical DCS. Complete correction of physiological imbalances and definitive surgery is carried out at a better equipped static hospital. TASC has shown to improve survival, extends benefit to greater number and helps to conserve precious resources. However TASC has its own limitations.

[Polytrauma and concomitant traumatic brain injury : The role of the trauma surgeon]

BACKGROUND

Concomitant traumatic brain injury (TBI) increases mortality and reduces quality of life of polytrauma patients. These facts demand effective treatment strategies while the growing specialization of medicine is questioning the role of the trauma surgeon in the management of these patients.

OBJECTIVES

Which factors influence outcome of polytrauma with concomitant TBI? Who should be responsible for the management of these patients and what is the limit of management?

MATERIALS AND METHODS

A literature search using Medline via PubMed was performed with Medical Subject Headings and text word search.

RESULTS

The crucial factors for outcome are absence of hypotension, adherence to pre- and in-hospital standards like fast transportation to appropriate centers, priority-based diagnostic and therapeutic strategies and strict adherence to principles of damage control surgery. Patients with polytrauma and TBI are treated by different specialties around the world based on the trauma system, geographic circumstances and resources. Investigations of operative and conservative management by different medical specialties showed comparable outcomes.

CONCLUSIONS

In an age of standardization and a high degree of specialization in the field of medicine, the trauma surgeon still seems to be able to ensure an optimal treatment of polytrauma and concomitant TBI by focusing on priority-based diagnostic and therapeutic strategies and adhering to principles of damage control surgery.

The effectiveness of hybrid treatment for sever multiple trauma: a case of multiple trauma for damage control laparotomy and thoracic endovascular repair

Background

Time is a crucial factor for the successful early management of the multi-trauma patient. Hybrid operating theaters, which support the integration of surgical treatment and interventional radiology, provide opportunities to reduce the time-to-surgery for life threatening conditions.

Case presentation

We describe the early successful treatment of a 54-year-old male who sustained multiple injuries when he was hit by a 1000 kg bale of wheat that fell from a height. He was admitted with hemorrhagic shock due to intra-abdominal bleeding, an unstable fracture of the pelvis, and blunt aortic injury, which was considered to be at high risk of rupture. External fixation was applied to the pelvis in the resuscitation bay, and the patient was transferred to a hybrid operating theater for treatment of both the intra-abdominal hemorrhage and blunt aortic injury. Damage control laparotomy and thoracic endovascular aortic repair were performed uneventfully.

Conclusions

Hybrid treatment, which combines emergency surgery and intraoperative interventional radiology, provides a prompt and appropriate management approach for the treatment of patients with severe multiple trauma and may improve patient outcomes.

Management of the open abdomen: clinical recommendations for the trauma/acute care surgeon and general surgeon

Traditionally, the surgical approach to managing abdominal injuries was to assess the extent of trauma, repair any damage and close the abdomen in one definitive procedure rather than leave the abdomen open. With advances in medicine, damage control surgery using temporary abdominal closure methods is being used to manage the open abdomen (OA) when closure is not possible. Although OA management is often observed in traumatic injuries, the extension of damage control surgery concepts, in conjunction with OA, for the management of the septic patient requires that the general surgeon who is faced with these challenges has a comprehensive knowledge of this complex subject. The purpose of this article is to provide guidance to the acute care and general surgeon on the use of OA negative pressure therapy (OA-NPT; ABTHERA™ Open Abdomen Negative Pressure Therapy System, KCI, an ACELITY Company, San Antonio, TX) for OA management. A literature review of published evidence, clinical recommendations on managing the OA and a case study demonstrating OA management using OA-NPT have been included.

Utility of Glissonean Pedicle Transection for Surgical Treatment of Severe Liver Trauma

The most common initial strategy for treatment of severe liver trauma is damage control in which hemostasis is achieved by perihepatic gauze packing and/or vascular embolization. However, we encounter patients in whom this strategy alone is not adequate. We have applied the principles of Glissonean pedicle transection, a technique that was originally devised to ensure safe and quick performance of planned hepatectomy for liver cancer, to 3 cases of severe liver trauma. We performed Glissonean pedicle ligation during damage control surgery in 2 patients and Glissonean pedicle transection during the definitive surgery in 1 patient. We describe the approaches and our experience with them, including operation times and outcomes. From our experience thus far, it seems that 8–12 h after the damage control procedure is appropriate for performing the definitive surgery. Although there are some problems posed by this strategy and cases to which it will not be applicable, the method seems to be particularly useful for cases of severe liver trauma in which the damage is extensive and involves the Glissonean pedicles near the hepatic hilus. We describe our 3 cases in detail and review our experience in light of the available literature.

Abbreviated closure for remote damage control laparotomy in extreme environments: A randomized trial of sutures versus wound clamps comparing terrestrial and weightless conditions

INTRODUCTION

Far-Forward Damage Control Laparotomies (DCLs) might provide direct-compression of visceral hemorrhage, however, suturing is a limiting factor, especially for non-physicians. We thus compared abbreviated skin closures comparing skin-suture (SS) versus wound-clamp (WC), on-board a research aircraft in weightlessness (0g) and normal gravity (1g).

METHODS

Surgeons conducted DCLs on a surgical-simulator; onboard the hangered-aircraft (1g), or during parabolic flight (0g), randomized to either WC or SS.

RESULTS

Ten surgeons participated. Two (40%) surgeons randomized to suture in 0g were incapacitated with motion-sickness, and none were able to close in either 1 or 0g. With WC, two completely closed in 1g as did three in 0g, despite having longer incisions (p = 0.016). Overall skin-closure with WC was significantly greater in both 1g (p = 0.016) and 0g (p = 0.008).

CONCLUSIONS

WC was more effective in 1g and particularly 0g. Future studies should address the utility of abbreviated WC abdominal closure to facilitate potential Far-Forward DCL.

Noncompressible Torso Hemorrhage

Noncompressible torso hemorrhage (NCTH) constitutes a leading cause of potentially preventable trauma mortality. NCTH is defined by high-grade injury present in one or more of the following anatomic domains: pulmonary, solid abdominal organ, major vascular or pelvic trauma; plus hemodynamic instability or the need for immediate hemorrhage control. Rapid operative management, as part of a damage control resuscitation strategy, remains the mainstay of treatment. However, endovascular techniques are evolving and may become more mainstream with the advent of hybrid rooms that can deliver concurrent open and radiologic/endovascular management of traumatic hemorrhage.

Role of the Open Abdomen in Critically Ill Patients

An open abdomen is common used in critically ill patients to temporize permanent abdominal closure. The most common reason for leaving the abdomen open by reopening a laparotomy, not closing, or creating a fresh laparotomy is the abdominal compartment syndrome. The open abdomen technique is also used in damage control operations and intra-abdominal sepsis. Negative pressure wound therapy may be associated with better outcomes than other temporary abdominal closure techniques. The open abdomen is associated with many early and late complications, including infections, gastrointestinal fistulas, and ventral hernias. Clinicians should be vigilant regarding the development of these complications.

Impact of urgent resuscitative surgery for life-threatening torso trauma

Purpose

This study investigated the advantages of performing urgent resuscitative surgery (URS) in the emergency department (ED); namely, our URS policy, to avoid a delay in hemorrhage control for patients with severe torso trauma and unstable vital signs.

Methods

We divided 264 eligible cases into a URS group (n = 97) and a non-URS group (n = 167) to compare, retrospectively, the observed survival rate with the predicted survival using the Trauma and Injury Severity Score (TRISS).

Results

While the revised trauma score and the injury severity score were significantly lower in the URS group than in the non-URS group, the observed survival rate was significantly higher than the predicted rate in the URS (48.5 vs. 40.2%; p = 0.038). URS group patients with a systolic blood pressure (SBP) <90 mmHg and a Glasgow coma scale (GCS) score of ≥9 had significantly higher observed survival rates than predicted survival rates (0.433 vs. 0.309, p = 0.008), (0.795 vs. 0.681, p = 0.004). The implementation of damage control surgery (DCS) was found to be a significant predictor of survival (OR 5.23, 95% CI 0.113–0.526, p < 0.010).

Conclusion

The best indications for the URS policy are an SBP <90 mmHg, a GCS ≥9 on ED arrival, and/or the need for DCS. By implementing our URS policy, satisfactory survival of patients requiring immediate hemostatic surgery was achieved.

Staged laparotomies based on the damage control principle to treat hemodynamically unstable grade IV blunt hepatic injury in an eight-year-old girl

BACKGROUND

Severe blunt hepatic injury is a major cause of morbidity and mortality in pediatric patients. Damage control (DC) surgery has been reported to be useful in severely compromised children with hepatic injury. We applied such a technique in the treatment of a case of hemodynamically unstable grade IV blunt hepatic injury in an eight-year-old girl. This case is the first to use multimodal approaches including perihepatic packing, temporary closure of the abdominal wall with a plastic sheet, transarterial embolization (TAE), and planned delayed anatomical hepatic resection in a child.

CASE PRESENTATION

An eight-year-old girl was run over by a motor vehicle and transferred to the emergency department of the local hospital. Her diagnoses were severe blunt hepatic injury (grade IV) with left femoral trochanteric fracture. No other organ injuries were observed. Because her hemodynamic state was stable under aggressive fluid resuscitation, she was transferred to our hospital for surgical management. On arrival at our institution about 4 h after the injury, her hemodynamic condition became unstable. Abdominal compartment syndrome also became apparent. Because her condition had deteriorated and the lethal triad of low BT, coagulopathy, and acidosis was observed, a DC treatment strategy was selected. First, emergent laparotomy was performed for gauze-packing hemostasis to control intractable bleeding from the liver bed, and the abdomen was temporarily closed with a plastic sheet with continuous negative pressure aspiration. Transarterial embolization of the posterior branch of the right hepatic artery was then carried out immediately after the operation. The lacerated right lobe of the liver was safely resected in a stable hemodynamic condition 2 days after the initial operation. Bleeding from the liver bed ceased without further need of hemostasis. She was transferred to the local hospital without any surgical complications on day 42 after admission. She had returned to her normal life by 3 months after the injury.

CONCLUSION

The DC strategy was found to be effective even in a pediatric patient with hemodynamically unstable severe blunt hepatic injury. The presence of the deadly triad (hypothermia, coagulopathy, and acidosis) and abdominal compartment syndrome was an indication for DC surgery.

Emergent laparotomy and temporary abdominal closure for the cirrhotic patient

BACKGROUND

Temporary abdominal closure (TAC) may be performed for cirrhotic patients undergoing emergent laparotomy. The effects of cirrhosis on physiologic parameters, resuscitation requirements, and outcomes following TAC are unknown. We hypothesized that cirrhotic TAC patients would have different resuscitation requirements and worse outcomes than noncirrhotic patients.

METHODS

We performed a 3-year retrospective cohort analysis of 231 patients managed with TAC following emergent laparotomy for sepsis, trauma, or abdominal compartment syndrome. All patients were initially managed with negative pressure wound therapy (NPWT) TAC with intention for planned relaparotomy and sequential abdominal closure attempts at 24- to 48-h intervals.

RESULTS

At presentation, cirrhotic patients had higher incidence of acidosis (33% versus 17%) and coagulopathy (87% versus 54%) than noncirrhotic patients. Forty-eight hours after presentation, cirrhotic patients had a persistently higher incidence of coagulopathy (77% versus 44%) despite receiving more fresh frozen plasma (10.8 units versus 4.4 units). Cirrhotic patients had higher NPWT output (4427 mL versus 2375 mL) and developed higher vasopressor infusion rates (57% versus 29%). Cirrhotic patients had fewer intensive care unit-free days (2.3 versus 7.6 days) and higher rates of multiple organ failure (64% versus 34%), in-hospital mortality (67% versus 21%), and long-term mortality (80% versus 34%) than noncirrhotic patients.

CONCLUSIONS

Cirrhotic patients managed with TAC are susceptible to early acidosis, persistent coagulopathy, large NPWT fluid losses, prolonged vasopressor requirements, multiple organ failure, and early mortality. Future research should seek to determine whether TAC provides an advantage over primary fascial closure for cirrhotic patients undergoing emergency laparotomy.

The management of colonic trauma in the damage control era

INTRODUCTION The purpose of this study was to audit our current management of colonic trauma, and to review our experience of colonic trauma in patients who underwent initial damage control (DC) surgery. METHODS All patients treated for colonic trauma between January 2012 and December 2014 by the Pietermaritzburg Metropolitan Trauma Service were included in the study. Data reviewed included mechanism of injury, method of management (primary repair [PR], primary diversion [PD] or DC) and outcome (complications and mortality rate). Results A total of 128 patients sustained a colonic injury during the study period. Ninety-seven per cent of the injuries were due to penetrating trauma. Of these cases, 56% comprised stab wounds (SWs) and 44% were gunshot wounds (GSWs). Management was by PR in 99, PD in 20 and DC surgery in 9 cases. Among the 69 SW victims, 57 underwent PR, 9 had PD and 3 required a DC procedure. Of the 55 GSW cases, 40 were managed with PR, 9 with PD and 6 with DC surgery. In the PR group, there were 16 colonic complications (5 cases of breakdown and 11 of wound sepsis). Overall, nine patients (7%) died. CONCLUSIONS PR of colonic trauma is safe and should be used for the majority of such injuries. Persistent acidosis, however, should be considered a contraindication. In unstable patients with complex injuries, the optimal approach is to perform DC surgery. In this situation, formal diversion is contraindicated, and the injury should be controlled and dropped back into the abdomen at the primary operation. At the repeat operation, if the physiological insult has been reversed, then formal repair of the colonic injury is acceptable.

Floating stoma: An alternative strategy in the context of damage control surgery

INTRODUCTION

Floating stoma (FS) is a strategy to be considered in the context of damage control surgery (DCS). The purpose of this study is to describe the technique used and the results of a series of patients where FS was used.

METHODS

Case series of relaparotomized patients at two emergency services in Temuco, Chile (2005-2014). In all of them, once drainage of septic focus or damage was controlled, the abdomen was left open with a Bogota bag (BB) and FS. Outcome variables were FS indications, morbidity, time to first replacement of BB, definitive maturation of the stoma (DMS), time to withdraw the BB and mortality.

RESULTS

FS was performed in 46 patients with a mean age of 49.3±21.1 years; 63% were female. The indication of FS was abdominal sepsis by secondary peritonitis (69.6%), abdominal trauma (17.4%), and mesenteric ischemia (13.0%). Morbidity was 37.0%. Median time to first replacement of BB, DMS and time to withdraw the BB were 84hours, 3.5 days and 49 days, respectively. Mortality was 19.6%.

CONCLUSION

FS is a temporary resource reserved for special surgical cases. It is associated with morbidity and mortality inherent with the severity of the patients on whom it can be used.

Military neurosurgery in operation: experience in the French role-3 medical treatment facility of Kabul

BACKGROUND

In 2009, during the war in Afghanistan, the increasing number of head injuries led to the deployment of a military neurosurgeon at the Kabul International Airport (KaIA) medical treatment facility, in March 2010. The main goal of this study was to depict the neurosurgical activity in this centre and to analyse its different aspects.

METHOD

A retrospective study of all the neurosurgical patients treated in KaIA from March 2010 to June 2013.

RESULTS

Three hundred and seventy-three interventions performed by the neurosurgeon deployed were reported for 373 surgeries, in 335 patients, representing 10.6 % of the overall surgical activity of the centre. Among the 69 interventions performed on soldiers, 57 surgeries were undertaken in emergency (82.6 %), while 12 were elective procedures (17.4 %). On the other hand, 289 surgeries were performed in civilian Afghans, with 126 emergency procedures in (43.6 %), against 163 elective interventions (56.4 %). Among the 44.5 % (n = 149) of the traumatic casualties, cerebral lesions represented 28.7 % (n = 96) and spinal lesions 12.4 % (n = 42). Ninety patients had multiple injuries. Additionally, patients without trauma accounted for 55.5 % (n = 186) of the overall population. Thus, 49 % (n = 164) were operated on for non-traumatic lesion of the spine. These were mostly civilian Afghans treated under medical aid to the population (90.2 %, n = 148/164).

CONCLUSIONS

The military neurosurgeon had two roles in KaIA: both to support the armed forces and to manage medical aid to the civilian population. This study gives food for thought on the neurosurgical needs in modern warfare, and on the skills required for the military neurosurgeon.

Advances in understanding role of enhanced recovery after surgery and damage control surgery in acute abdominal disease

Enhanced recovery after surgery and damage control surgery have been gradually applied to clinical surgery in recent years, aimed to reduce perioperative stress response in surgical patients. Research on the perioperative period of selective surgery proves that enhanced recovery after surgery and damage control surgery play an important role in reducing perioperative stress reaction, especially in patients with acute abdominal pain. This article briefly summarizes the recent progress in understanding the role of enhanced recovery after surgery and damage control surgery in acute abdominal disease.

Peri-hepatic gauze packing for the control of haemorrhage during liver transplantation: A retrospective study

BACKGROUND

Albeit accepted in the trauma setting, use of peri-hepatic gauze packing has been rarely reported during liver transplantation.

AIMS

To assess the results of packing in liver transplantation.

METHODS

We reviewed clinical characteristics, intraoperative events and postoperative outcome of consecutive adult liver transplantation recipients between 2003 and 2013. Patients treated with packing were compared to no-packing patients and to matched controls selected using a propensity score.

RESULTS

Of 1396 recipients, 107 were treated with packing for peri-hepatic bleeding (76.6%), allograft damage (12.1%) or partial outflow obstruction (11.2%). Urgent reoperation for ongoing haemorrhage was required in 6 (5.6%). Correction of haemodynamic and coagulation parameters was constantly achieved. Overall, patient (90% vs. 98%, p<0.001) and graft (83.2% vs. 94.7%, p<0.001) 3-month survival was significantly reduced in packing patients. However, after matching, no significant difference was observed in patient (89.3% vs. 95.2%, p=0.12) and graft (83.5% vs. 92.2%, p=0.06) 3-month survival. Patient survival was associated with recipient age (HR 2.59; p=0.04) and donor age × recipient MELD (HR 2.04; p=0.02), but not with packing (HR 1.81; p=0.29).

CONCLUSIONS

In our experience, packing was a valuable adjunct to conventional means of haemostasis during liver transplantation and, after accounting for confounding covariates, was not associated with inferior outcomes.

Management of pancreatic injuries during damage control surgery: an observational outcomes analysis of 79 patients treated at an academic Level 1 trauma centre

BACKGROUND

This study evaluated factors influencing mortality in a large cohort of patients who sustained pancreatic injuries and underwent DCS.

METHODS

A prospective database of consecutive patients with pancreatic injuries treated at a Level 1 academic trauma centre was reviewed to identify those who underwent DCS between 1995 and 2014.

RESULTS

Seventy-nine (71 men, median age: 26 years, range 16-73 years, gunshot wounds = 62, blunt = 14, stab = 3) patients with pancreatic injuries (35 proximal, 44 distal) had DCS. Fifty-nine (74.7 %) patients had AAST grade 3, 4 or 5 pancreatic injuries. The 79 patients had a total of 327 associated injuries (mean: 3 per patient, range 0-6) and underwent a total of 187 (range 1-7) operations. Vascular injuries (60/327, 18.3 %) occurred in 41 patients. Twenty-seven (34.2 %) patients died without having a second operation. The remaining 52 patients had two or more laparotomies (range 2-7). Overall 28 (35 %) patients underwent a pancreatic resection either during DCS (n = 18) or subsequently as a secondary procedure (n = 10) including a Whipple (n = 6) when stable. Overall 43 (54.4 %) patients died. Mortality was related to associated vascular injuries overall (p < 0.01), major visceral venous injuries (p < 0.01) and combined vascular and total number of associated organs injured (p < 0.04).

CONCLUSIONS

Despite the magnitude of their combined injuries and the degree of physiological insult, DCS salvaged 45 % of critically injured patients who later underwent definitive pancreatic surgery. Mortality correlated with associated vascular injuries overall, major visceral venous injuries and the combination of vascular plus the total number of associated organs injured.

Damage control management of innominate artery injury with tracheostomy

Innominate artery injury is a rare, but catastrophic complication of tracheostomy. We present a case of severe hemorrhagic shock in a 79-year-old male with innominate artery injury that occurred during tracheostomy. Despite temporary innominate artery isolation, the regional forehead saturation was 60 % without laterality. Because adequate cerebral blood flow was apparently maintained through collateral flow, we ligated the innominate, right carotid, and subclavian arteries. We confirmed adequate blood flow to the brain and the right subclavian artery through collateral circulation after ligation using computed tomographic angiography. A damage control management, which involves ligating the injured innominate artery to arrest hemorrhage and monitoring regional forehead saturation for brain ischemia, can be a considerable procedure for the treatment of severe hemorrhagic shock due to innominate artery injury.

Experience of damage control trauma laparotomy in a limited resource healthcare setting: A retrospective Cohort Study

INTRODUCTION

Damage control surgery (DCS) is an established option for managing severely injured trauma patients. However, its role in the management of similar patients in the developing world is debatable. The purpose of this study is to describe characteristics and outcomes of patients undergoing DCS.

METHODS

All trauma patients requiring laparotomies from 1996 to 2011 at a tertiary care hospital in South Asia were reviewed. DCS was defined in a patient who underwent a truncated laparotomy where the fascia was primarily left open, with the intention of physiological optimization in the Intensive Care Unit, followed by definitive surgery. The primary outcome was in-hospital mortality. Multivariate logistic regression was used to determine the independent predictors of mortality after adjustment for potential confounders.

RESULTS

Of 258 patients, 47 underwent DCS. 40% patients were transferred from other hospitals. The time between injury and operation was 152 minutes (IQR: 90-330). Intra-operative laboratory parameters revealed a median pH of 7.16 (IQR: 7.10-7.27), median temperature of 34.7 (IQR: 34.0-35.4) and median PT of 15.9 (IQR: 12.4-21.2). 55% of the patients survived to discharge from hospital. Of those who died, 86% died before the first take back operation. Packed red blood cell transfusion and vascular injury were independently associated with mortality.

DISCUSSION

Damage control surgery is feasible in developing countries, with more than 50% survival reported at one hospital. Future research should focus on critical care management.

CONCLUSION

Damage Control trauma laparotomy is feasible in tertiary care hospitals with multidisciplinary trauma teams in lesser-developed countries.

Damage control resuscitation: lessons learned

BACKGROUND

Damage control resuscitation describes an approach to the early care of very seriously injured patients. The aim is to keep the patient alive whilst avoiding interventions and situations that risk worsening their situation by driving the lethal triad of hypothermia, coagulopathy and acidosis or excessively stimulating the immune-inflammatory system. It is critical that the concepts and practicalities of this approach are understood by all those involved in the early management of trauma patients. This review aims to summarise this and discusses current knowledge on the subject.

INTERVENTIONS

Damage control resuscitation forms part of an overall approach to patient care rather than a specific intervention and has evolved from damage control surgery. It is characterised by early blood product administration, haemorrhage arrest and restoration of blood volume aiming to rapidly restore physiologic stability. The infusion of large volumes of crystalloid is no longer appropriate, instead the aim is to replace lost blood and avoid dilution and coagulopathy. In specific situations, permissive hypotension may also be of benefit, particularly in patients with severe haemorrhage from an arterial source. As rapid arrest of haemorrhage is so important, team-based protocols that deliver patients rapidly but safely, via CT scan where appropriate, to operating theatres or interventional radiology suites form a critical part of this process.

CONCLUSIONS

Given that interventions are so time dependent in the severely injured, it is likely that by further improving trauma systems and protocols, improvements in outcome can still be made. Further research work in this area will allow us to target these approaches more accurately to those patients who can benefit most.

Damage control surgery and combat-related maxillofacial and cervical injuries: a systematic review

Damage control surgery involves rapid assessment, life-saving resuscitation, and abbreviated surgery for a patient with severe injuries. Traditionally the concept of damage control surgery has been restricted to penetrating abdominal injuries, but more recently it has been expanded to areas outside of the abdomen including the maxillofacial and neck regions. However, we know of little evidence that, when applied to injuries to the face and neck, it changes outcomes. We systematically reviewed published papers to identify those that discussed damage control in the context of combat-related trauma of the face and neck. We identified three papers that discussed the principles of managing combat-related maxillofacial injuries, all three of which were review articles that advocated the use of damage control principles in facial injuries either in isolation or as part of a multisystem approach. Anecdotal experience and opinion indicates that the concept of damage control is applicable when managing combat-related injuries of the face and neck, but no outcomes were confirmed. Further studies are required to validate the concept.

Transcatheter thrombolysis combined with damage control surgery for treatment of acute mesenteric venous thrombosis associated with bowel necrosis: a retrospective study

OBJECTIVE

This study aims to evaluate the clinical outcomes of transcatheter thrombolysis in acute superior mesenteric venous thrombosis (ASMVT) associated with bowel necrosis.

METHODS

A retrospective study of six patients with ASMVT treated with catheter-directed thrombectomy/thrombolysis and damage control surgery at Jinling Hospital (Nanjing, China) between 2010 and 2013 was conducted. Demographics, past medical history, risk factors, therapeutic methods and effects, mortality, and follow-up of the study population were assessed.

RESULTS

Five of six patients underwent arteriovenous combined thrombolysis, while one patient underwent arterial thrombolysis. All patients required damage control surgery, and four of these patients underwent temporary abdominal closure. All patients survived and were free of recurrence.

CONCLUSIONS

Transcatheter thrombectomy/thrombolysis and damage control surgery could help avoid extensive bowel resection, prevent short bowel syndrome and reduce mortality for critically ill patients with acute mesenteric venous thrombosis associated with bowel necrosis.

Maxillofacial and neck trauma: a damage control approach

Severe maxillofacial and neck trauma exposes patients to life threatening complications such as airway compromise and hemorrhagic shock. These conditions require rapid actions (diagnosis and management) and a strong interplay between surgeons and anesthesiologists. Effective airway management often makes the difference between life and death in severe maxillofacial and neck trauma and takes initial precedence over all other clinical considerations. Damage control strategies focus on physiological and biochemical stabilization prior to the comprehensive anatomical and functional repair of all injuries. Damage control surgery (DCS) can be defined as the rapid initial control of hemorrhage and contamination, temporary wound closure, resuscitation to normal physiology in the intensive care unit (ICU) and subsequent reexploration and definitive repair following restoration of normal physiology. Damage control resuscitation (DCR) consists mainly of hypotensive (permissive hypotension) and hemostatic (minimal use of crystalloid fluids and utilization of blood and blood products) resuscitation. Both strategies should be administered simultaneously in all of these patients.

[Enterolithotomy and early cholecystectomy, an application of damage control surgery for patients with gallstone ileus]

BACKGROUND

Recurrent gallstone ileus is an uncommon mechanical intestinal obstruction secondary to occlusion of the intestine by an intraluminal biliary calculus.

CLINICAL CASE

Female, 75 years old, ischaemic heart disease (stent), arrived in our department complaining of abdominal pain and vomiting. Computed tomography showed gallstone ileus. The patient underwent an enterotomy with gallstone removal. Three months later, the patient came back with the same clinical symptoms and signs. A new computed tomography highlighted a gallstone ileus again. Enterolithotomy and gallstone removal, cholecystectomy and closure of cholecystoduodenal fistula were performed. The patient had a prolonged hospital stay due to the development of congestive heart failure. Case 2. Male, 71 years old, ischaemic heart disease and aortocoronary bypass, seen in our department complaining of vomiting. Computed tomography showed aerobilia and gallstone ileus. The patient underwent an urgent enterolithotomy. Seven months later, the patient came back with the same clinical symptoms and signs. Computed tomography showed a new gallstone ileus. An enterotomy and gallstone removal, cholecystectomy and closure of cholecystoduodenal fistula were performed. The patient died due to multi-organ failure in post-surgery period.

CONCLUSION

In the elderly patients with concomitant medical illnesses with the risk of a second laparotomy, it is justifiable to reconsider the definitive repair in the treatment of gallstone ileus. The enterolithotomy in acute phase followed by early cholecystectomy (4-8 weeks) may be a safe method for eliminating, not only the possibility of recurrent gallstone ileus, and probably the need for a second laparotomy, but also the exceptional possibility of developing a gallbladder carcinoma.

Upper G.I. hemorrhage from glass fragments' ingestion in a patient with jejunal diverticula - Case report

INTRODUCTION

Acute upper gastrointestinal bleeding is a common emergency. The ingestion of foreign bodies represents a less frequent cause of bleeding, but it is equally life-threatening, especially if the patient does not report the incident.

PRESENTATION OF CASE

We are reporting the case of a 77-year-old patient with a bleeding caused by ingestion of glass fragments with co-existing jejunal diverticula.

DISCUSSION

The ingestion of foreign bodies is a rare, mostly accidental event. Another possible source of upper G.I. bleeding is jejunal diverticula; in this case, the examination of the specimens showed evidence of glass ingestion fragments as the likely cause of bleeding.

CONCLUSION

Surgeons should be aware that patients may fail to report correctly on the possible causes of bleeding, misleading the diagnosis, and delaying the diagnostic routes.

Intra-abdominal Infections

Intra-abdominal infections are multifactorial, but all require prompt identification, diagnosis, and treatment. Resuscitation, early antibiotic administration, and source control are crucial. Antibiotic administration should initially be broad spectrum and target the most likely pathogens. When cultures are available, antibiotics should be narrowed and limited in duration. The method of source control depends on the anatomic site, site accessibility, and the patient's clinical condition. Patient-specific factors (advanced age and chronic medical conditions) as well as disease-specific factors (health care-associated infections and inability to obtain source control) combine to affect patient morbidity and mortality.

Management of liver injuries: predictors for the need of operation and damage control surgery

Management of liver injuries: Predictors for the need of operation and damage control surgery,

INTRODUCTION

The advancement in the management of liver injuries, including the use of non-operative management (NOM), damage control surgery (DCS) and angiographic embolisation (AE); has resulted, in improvement of outcomes. The aim of this study is to analyse the outcome of liver injury patients in our institution and to identify predictors for the need of operative management (OM) and DCS.

PATIENTS AND METHODS

We retrospectively reviewed 218 patients with liver injury admitted to King, Chulalongkorn Memorial Hospital from May 2002 to May 2011. Data collection included demographic, data, emergency department parameters, detail of liver injuries, and outcome in terms of mortality rate (MR). Stepwise logistic regression was performed to identify mutually independent predictors for the need of OM and DCS.

RESULTS

Two hundred and eighteen patients with liver injury were identified (156 blunt and 62 penetrating). One hundred fifty-four patients (70.6%) underwent OM due to hemodynamic instability, (96), peritonitis (24), and other indications (34). DCS (perihepatic packing and temporary abdominal, closure) was utilised in 45 patients. NOM was attempted in 64 patients (29.4%), 6 of these, subsequently required laparotomy (success rate 90.6%). Angiography was performed in 47 patients, (14 in NOM, 33 in OM) and 40 patients received AE (10 in NOM, 30 in OM). Overall MR was 17.4%, the, MR was significantly higher in OM than in NOM (24 vs. 1.6%; p<0.001, OR 19.92). The mutually independent predictors for the need of operation were low Glasgow Coma Score (GCS), penetrating mechanism, tachycardia, and hypotension; while the independent predictors for DCS were high grade (>4) liver injury, tachycardia, and blunt mechanism.

CONCLUSIONS

Overall MR of liver injury patients was 17.4%. NOM carried a low MR and should be, attempted in the absence of hemodynamic instability and peritonitis. Patients with low GCS, penetrating injury, tachycardia, and hypotension were more likely to require operation. DCS should be considered while operating on patients with high grade liver injury, tachycardia, and blunt mechanism.

Intraintestinal drainage as a damage control surgery adjunct in a hypothermic traumatic shock swine model with multiple bowel perforations

BACKGROUND

Temporary bowel ligation (TL) has been proposed to prevent contamination as a damage control procedure in multiple bowel perforations. However, bacteria translocation and intestinal ischemia may develop in a prolonged duration. We here hypothesized that intraintestinal drainage combined with temporary ligation (D-TL) would decrease intestinal injury and improve survivals in a gunshot multiple bowel perforation swine model in the setting of a damage control surgery.

MATERIALS AND METHODS

The abdomen was shot one time with an experimental modified gun whereas pigs were hemorrhaged to a mean arterial pressure of 40 mm Hg and maintained in shock for 40 min. Cold lactated Ringer solution was gradually infused to induce hypothermia. Animals were randomized to primary anastomosis, TL and intraintestinal D-TL groups (n = 8). Animals were resuscitated for 12 h with the shed blood and lactated Ringer solution. Delayed anastomosis was performed in TL and D-TL animals after resuscitation. Surviving animals were humanely killed 24 h after operation. Systemic hemodynamic parameters were recorded and blood samples were obtained for biochemical assays. Intra-abdominal pressure, portal vein and peripheral vein bacterial cultures, small intestine hematoxylin-eosin staining, and transmission electron microscopy examination were performed at 0, 2, 6, 12, and 24 h after the surgery.

RESULTS

All animals suffered extreme physiologic conditions as follows: hypothermia, severe acidosis, hypotension, and depressed cardiac output. Compared with the primary anastomosis and TL group, D-TL animals required less resuscitation fluid, suffered a lower intra-abdominal hypertension and bacterial translocation, normalized lactate levels faster, had lower serum creatine kinase, aspartate aminotransferase levels and tissue TNF-α level, and nuclear factor-kB activations and thus had greater early survival.

CONCLUSIONS

Compared with primary intestinal anastomosis and TL, rapid bowel ligation combined with intraintestinal drainage as a damage control adjunct improved survivals in a multiple bowel perforation swine model in the setting of damage control surgery.

Goal directed fluid resuscitation decreases time for lactate clearance and facilitates early fascial closure in damage control surgery

BACKGROUND

Damage-control surgery frequently results in open abdomen. The objective of this study was to determine whether resuscitation with goal-directed fluid therapy (GDT) using "dynamic" hemodynamic indices via modern pulse contour analysis devices such as the FloTrac Vigileo monitor leads to lower fluid requirements, subsequent quicker abdominal closure, and overall improved outcomes in these patients.

METHODS

Patients admitted to the surgical intensive care unit with open abdomen were retrospectively reviewed. Those resuscitated with Vigileo-guided GDT were matched to those resuscitated by static clinical parameters.

RESULTS

Total fluid intake and vasopressor requirements were similar in both groups. GDT with the Vigileo allowed earlier lactate clearance and reduced the number of days until abdominal wall closure by an average of .99 days.

CONCLUSIONS

Vigileo-mediated GDT did not affect fluid volume or vasopressor use in open abdomen patients, but facilitated more effective resuscitation and decreased the number of days to fascial closure, leading to shorter hospital stays. Vigileo-mediated GDT, therefore, may improve overall outcomes in open abdomen patients.
