Outcomes of a new slowly resorbable biosynthetic mesh (Phasix (TM)) in potentially contaminated incisional hernias : a prospective, multi-center, single-arm trial

Background: Resorbable biomaterials have been developed to reduce the amount of foreign material remaining in the body after hernia repair over the long-term. However, on the short-term, these resorbable materials should render acceptable results with regard to complications, infections, and reoperations to be considered for repair. Additionally, the rate of resorption should not be any faster than collagen deposition and maturation; leading to early hernia recurrence. Therefore, the objective of this study was to collect data on the short-term performance of a new resorbable biosynthetic mesh (Phasix (TM)) in patients requiring Ventral Hernia Working Group (VHWG) Grade 3 midline incisional hernia repair. Materials and methods: A prospective, multi-center, single-arm trial was conducted at surgical departments in 15 hospitals across Europe. Patients aged >= 18, scheduled to undergo elective Ventral Hernia Working Group Grade 3 hernia repair of a hernia larger than 10 cm(2) were included. Hernia repair was performed with Phasix (TM) Mesh in sublay position when achievable. The primary outcome was the rate of surgical site occurrence (SSO), including infections, that required intervention until 3 months after repair. Results: In total, 84 patients were treated with Phasix (TM) Mesh. Twenty-two patients (26.2%) developed 32 surgical site occurrences. These included 11 surgical site infections, 9 wound dehiscences, 7 seromas, 2 hematomas, 2 skin necroses, and 1 fistula. No significant differences in surgical site occurrence development were found between groups repaired with or without component separation technique, and between clean-contaminated or contaminated wound sites. At three months, there were no hernia recurrences. Conclusion: Phasix (TM) Mesh demonstrated acceptable postoperative surgical site occurrence rates in patients with a Ventral Hernia Working Group Grade 3 hernia. Longer follow-up is needed to evaluate the recurrence rate and the effects on quality of life. This study is ongoing through 24 months of follow-up

First case of Candida auris infection in Belgium in a surgical patient from Kuwait

Objective and importance:Candida auris is a relatively new yeast species and an emerging opportunistic pathogen. It was first reported in 2009 in East Asia, as a difficult-to-identify Candida species of uncertain clinical relevance. In recent years, it has appeared globally as a cause of invasive infections, not infrequently eliciting nosocomial outbreaks. Species identification in clinical laboratories has been challenging, as traditional phenotypic and biochemical methods have been generally unreliable. Clinical management is often complicated by multidrug resistance in many isolates. Additionally, C. auris has demonstrated an unusual ability for persistence in the hospital environment and in asymptomatic patients. We present the first Belgian case of C. auris infection along with a brief review of the literature.Clinical presentation: A patient was referred from Kuwait for surgical treatment after a complicated bariatric procedure. Few days after transferral, she developed a catheter-related blood stream infection with C. auris. We obtained a low-confidence identification of C. auris with the Bruker Biotyper MALDI-TOF MS system (Bruker Corporation, Billerica, MA, U.S.A.), and of Candida haemulonii with the Vitek YST identification system, version 7.01 (bioMérieux, Marcy-L'Etoile, France). Definite identification was obtained using Internal Transcribed Spacer (ITS) sequencing. As most C. auris isolates, our strain was resistant to fluconazole, and the patient was eventually treated with catheter removal and anidulafungin therapy. We documented persistence of C. auris clones with acquired echinocandin resistance in our patient up to 18 months after the infection.Conclusion: Clinicians and microbiologists should be aware of this globally emerging yeast, that poses important challenges in identification, treatment and hospital infection control.status: publishe

Background: The incidence of incisional hernias after abdominal aortic aneurysm repair is high. Prophylactic mesh-augmented reinforcement during laparotomy closure has been proposed in patients at high risk of incisional hernia. Methods: A multicenter randomized trial was conducted on patients undergoing elective abdominal aortic aneurysm repair through a midline laparotomy (Clinical.Trials.gov: NCT00757133). In the study group, retromuscular mesh-augmented reinforcement was performed with a large-pore polypropylene mesh (Ultrapro, width 7.5cm). The primary endpoint was the incidence of incisional hernias at 2-year follow-up. Results: Between February 2009 and January 2013, 120 patients were recruited at 8 Belgian centers. Patients' characteristics at baseline were similar between groups. Operative and postoperative characteristics showed no difference in morbidity or mortality. The cumulative incidence of incisional hernias at 2-year follow-up after conventional closure was 28% (95% confidence interval [CI], 17%-41%) versus 0% (95% CI, 0%-6%) after mesh-augmented reinforcement (P < 0.0001; Fisher exact test). The estimated freedom of incisional hernia curves (Kaplan-Meier estimate) were significantly different across study arms ((2) = 19.5, P < 0.0001; Mantel-Cox test). No adverse effect related to mesh-augmented reinforcement was observed, apart from an increased mean time to close the abdominal wall for mesh-augmented reinforcement compared with the control group: 46 minutes (SD, 18.6) versus 30 minutes (SD, 18.5), respectively (P < 0.001; Mann-Whitney U test). Conclusions: Prophylactic retromuscular mesh-augmented reinforcement of a midline laparotomy in patients with abdominal aortic aneurysm is safe and effectively prevents the development of incisional hernia during 2 years, with an additional mean operative time of 16 minutes

Prevention of Incisional Hernias by Prophylactic Mesh-augmented Reinforcement of Midline Laparotomies for Abdominal Aortic Aneurysm Treatment 5-year Follow-up of a Randomized Controlled Trial

peer reviewed[en] INTRODUCTION: The incidence of incisional hernias (IHs) after open repair of an abdominal aortic aneurysm (AAA) is high. Several randomized controlled trials have reported favorable results with the use of prophylactic mesh to prevent IHs, without increasing complications. In this analysis we report on the results of the 60-month follow-up of the PRIMAAT trial (Ann Surg 2016; 263(4): 638-45). METHODS: In a prospective, multicenter, open label, randomized design, patients were randomized between prophylactic retrorectus mesh reinforcement (MESH group), and primary closure of their midline laparotomy after open AAA repair (NOMESH group). This article reports on the results of clinical follow-up after 60 months. If performed, ultrasonography or computed tomography were used for the diagnosis of IHs. RESULTS: Of the 120 randomized patients, 114 were included in the intention-to-treat analysis. Thirty-three patients in the NOMESH group (33/58-56.9%) and 34 patients in the MESH group (34/56-60.7%) were evaluated after 5 years. In each treatment arm, 10 patients died between the 24-month and 60-month follow-up. The cumulative incidence of IHs in the NOMESH group was 32.9% after 24 months and 49.2% after 60 months. No incisional hernias were diagnosed in the MESH group. In the NOMESH group, 21.7% (5/23) underwent reoperation within 5 years due to an IH. CONCLUSION: Prophylactic retrorectus mesh reinforcement after midline laparotomy for the treatment of AAAs safely and effectively decreases the rate of IHs. The cumulative incidence of IHs after open AAA repair, when no mesh is used, continues to increase during the first 5 years after surgery, which leads to a substantial rate of hernia repairs
