Multidisciplinary approach in surgical pressure ulcer therapy after spinal cord injury

Multidisciplinární přístup v chirurgické léčbě dekubitů u pacientů s míšní lézí

Chirurgická léčba rozsáhlých dekubitů u pacientů s traumatickou míšní lézí stále představuje velkou výzvu a často opomíjenou kapitolu, s níž je celá řada odborností denně konfrontována. Léčba pacientů často vyžaduje multidisciplinární spolupráci napříč nejen chirurgickými obory. Právě úzká spolupráce s výživovým specialistou, mikrobiologem a pracovníky z chirurgických oborů je mnohdy jedinou možností k úspěšné terapii. Cílem příspěvku je ve stručnosti shrnout základní parametry multidisciplinární spolupráce při léčbě rozsáhlých dekubitů u pacientů s míšní lézí. Výše zmíněný přehled v krátkosti demonstrujeme na sérii kazuistik z naší každodenní praxe. V diskuzi se zabýváme rolí jednotlivých chirurgických specializací, významem nutriční podpory a řešením infekčních komplikací.

Summary

Surgical treatment of extensive pressure ulcers in patients with spinal cord injury still represent a major challenge and often neglected part of care with which many experts is confronted daily. Treatment of these patients often requires extensive multidisciplinary approach across, not only, surgical disciplines. Close cooperation with a nutritionist, microbiologist and other surgical specialists is often the only way to successfully manage the problem. The aim of this publication is to briefly summarize the basic parameters in multidisciplinary collaboration in the treatment of large pressure ulcers in patients with spinal cord lesions. We then briefly demonstrate the above mentioned issues on a series of case reports resulting from our daily practice and then discuss the role of individual surgical specializations, the importance of nutritional support and the solution of infectious complications.

Introduction

Pressure ulcers after spinal cord injury (SCI) represent a difficult problem leading to repeated hospitalizations, multiple operations and potentially devastating complications. This problem presents a challenge for patients, nurses and doctors [1]. Patients with SCI and its associated comorbidities are among the highest risk population for developing pressure ulcers. The incidence of pressure ulcers in the SCI population is 25– 66% [2,3].

In this publication we describe the need for extensive multidisciplinary approach in surgical treatment of pressure ulcers in SCI patients. In the individual chapters we describe the importance of nutritional support, microbiological surveillance and interdisciplinary cooperation within the surgical closure of the defect. We then demonstrate the discussed topics with several examples based on our clinical practice.

Case series

Case report 1

A 68-year-old paraplegic patient was admitted to our clinic in septic condition with an extensive pressure ulcer in the sacral region (Fig. 1). Multiple necrectomy of the whole region was performed and intensive antibiotic therapy was introduced (further adjusted according to the results of cultivation and antibiotic sensitivity). Due to repeated contamination of the wound with stools (within closed distance of anus) and mainly the presence of the posterior wall of the rectum just below the bottom of the defect, it was decided that a sigmoidostomy would be created by a general surgeon. The condition was further complicated by the development of the ileus state, with the necessity of surgical revision due to rotation and malposition of intestinal loops. Derotation, desuflasion and re-suture were performed during revision surgery. Following the surgery, the post-operative period was uneventful. The closure of the pressure ulcer in such a stressful situation and under these conditions would be a high risk, especially in cases of wound healing in fields that have been re-operated several times. By this point, the patient was in malnutrition, hypoproteinemia and all his reserves were exhausted. Therefore, a conservative approach and intensive correction of all macro- and micronutrients was priority. Surgical closure of the wound was postponed for several weeks after the patient’s complete realimentation. The final wound closure was performed one month later. The entire defect was covered by a large fasciocutaneous flap from the left half of the sacral/ gluteal region (Fig. 2). The whole hospitalization period was managed under precise microbiological surveillance and targeted antibiotic therapy.

Case report 2

As our second case, we present a 43-year-old paraplegic man, who was admitted to our clinic with large infected pressure ulcers in the sacral and right trochanteric region (Fig. 3). Both defects were severely contaminated by multiresistant strains of Pseudomonas aeruginosa and Acinetobacter baumanii, which required prolonged and challenging antibiotic therapy with close cooperation with the Department of Clinical Microbiology. Preoperative examination and CT scans showed extensive osteomyelitis in the right proximal femur. In cooperation with an orthopedic surgeon, we performed radical resection of the proximal femur and subsequently radical necrectomy of both defects. At first, we decided to close the smaller and more superficial defect in the sacral region with a V-Y fasciocutaneous flap. In the trochanteric region, the defect was large and deep so we decided to apply NPWT (Negative Pressure Wound Therapy) for promoting granulation and remediation of infection. We sustained the vacuum assisted closure therapy for several weeks, together with intense nutrition support. Finally, after 1 month we could close the defect with a large transposition flap (Fig. 4). Further healing and the post-operative period were without any complication.

Discussion

University Hospital Brno provides one of four SCI in the Czech Republic. As a part of this service, a multidisciplinary surgical team was established for the surgical management of pressure ulcers arising in this patient group. Despite the growing possibilities of conservative therapy, the extensive pressure ulcers of grades III and IV can only be closed by surgical excision and reconstruction. Due to the fact that such an intervention is generally an elective surgical procedure, patient’s overall condition and chronic medical comorbidities (e. g. diabetes mellitus, hypertension, malnutrition, and anemia) have to be compensate by the multidisciplinary team before a patient is considered a good candidate for surgery [1]. If the ulcer or ulcers are in close proximity to the anus, clinical judgment should address the need for bowel diversion by colostomy. The presence of stool significantly compromises wound healing and makes its toilet virtually impossible. Furthermore, the close proximity of the rectum to the defect may complicate the surgical procedure and its possible perforation may result in fatal complications [4]. The same applies to the perineal region – the creation of a temporary or permanent urinary diversion should be considered here. The presence of an orthopedic surgeon is often required due to osteomyelitis, which will also have a significant impact on further surgical plans. Often, a radical osteotomy is required before final wound closure [5]. Only after proper radical surgical debridement, including of bone structures and conceiving a proper surgical field, the defect can be closed by a plastic surgeon. Surgical management of pressure ulcer closure involves a spectrum of options, from simple debridement with direct closure, to skin grafting, fasciocutaneous flaps, myocutaneous flaps or even free flaps [1]. The choice of flap reconstruction always depends on a number of factors such as anatomical location, reoperated terrain, general condition and surgeon‘s preference [4]. Considering the spectrum of patients with often neglected chronic wounds and a very poor overall condition, it is clear that the resulting surgical effect is burdened with a corresponding percentage of complications and recurrences. Scientific sources show different percentages of complications. For example, Sameem et al reports complications ranging from 9– 20%, depending on the type of flap chosen. The most frequent complications in their study were flap necrosis (partial), wound dehiscence, infection and recurrence of pressure ulcer [6]. The ideal nutritional intake continues to be discussed to this day. Energy, protein, arginine, and micronutrients are all essential for proper wound healing. Proteins play the most important role in the healing process and are essential in the fibroblast proliferation process, angiogenesis, collagen synthesis and overall in tissue reparation [7], In 2009, National Pressure Ulcer Advisory Panel introduced general guidelines for the treatment and prevention of pressure ulcers, these were updated in 2014 [8]. For pressure ulcer stage III/ IV, recommended protein intake goes up to 2 g/ kg. The key role of protein intake is well demonstrated in a study presented by Crowe et al [9]. The group receiving higher protein (1.8 g protein per kg body weight) demonstrated nearly a two-fold greater rate of healing than those randomized to lower protein intake (1.2 g protein per kg body weight). The role of carbohydrates, fats and micronutrients is equally important. To prevent protein-energy malnutrition and improve wound healing, the diet should be adequate in energy in the form of carbohydrates, fat and protein. Infection of a pressure ulcer may result in soft tissue and bone infections: cellulitis, abscess formation, bursitis, and osteomyelitis of bone underlying the wound bed [10]. In SCI patients, it is one of the most common causes of bacteremia [11]. Control of wound colonization and infection should always be one of the biggest priorities in treatment protocol [1]. Precise microbiological surveillance should be strictly conducted in all patients, along with targeted antibiotic administration based on sensitivity. This is the only way to prevent an increase in antibiotic resistance and at the same time to successfully eradicate pathogens in an effort to prevent further dissemination [12].

Conclusion

Surgical treatment of pressure ulcers in patients after SCI is often a very complicated process involving many aspects of surgery. Today, correct and effective treatment is possible due to large collaboration in a multidisciplinary team. It is the presence of a diverse range of experts, not only from the surgical field, that has contributed to the development in this often neglected issue.
