Abstract

Background: Transoral spine surgery is specific due to both its surgical approach and the spectrum of diseases it targets. Patients with high age and elevated clinical frailty scores are often involved, and there are reports of increased risks of surgical site infection (SSI) due to extended exposures requiring maxilotomy or mandibulotomy. Our case series describes surgical wound complications under the meticulous application of individualized perioperative multimodal management.

Methods: Our primary outcome was the occurrence of SSI and the secondary outcome was the occurrence of other noninfectious wound complications evaluated in 22 adult patients who consecutively underwent the transoral spine surgery from 2001 to 2018 (trauma – C2, cervical nonunion: 6 patients, 27%; tumor: 4 patients, 18%; osteomyelitis: 6 patients, 27%; other non-traumatic cases: 6 patients, 27%). Structuralized data comprising parameters related to nosocomial infections after spine surgery were continuously processed and put into specialized database of preventive multimodal nosocomial infection control protocol that was used as a main source of analyzed parameters. The mean age of studied cohort was 54.9 ± 15.5 years, with 68% males, mean body mass index (BMI) 24.9 ± 5.22, and the mean clinical frailty score was 2.59 ± 1.07. There were 7 patients (32%) who only had the transoral approach and 15 patients (68%) having this approach followed by additional posterior approach. We observed SSI from all wound complications for up to one year after surgery.

Results: There were 4 (18%) superficial wound complications from transoral approach, but none of them were infected. We had 2 patients (13%) with deep wound infections after subsequent posterior approach, but only one (4.5%) was classified as SSI.

Conclusions: We describe the wound complications and the incidence of SSI in a series of 22 patients after the transoral surgery. Considering the average values of the clinical frailty score reaching 2.59, American Society of Anesthesiologists score of 2.73, and the BMI of 26.87, the transoral spine surgery did not seem to be a considerable risk for SSI in the analyzed cohort, provided preventive perioperative multimodal management is properly individualized and

Abstract

Purpose Infected orthopaedic metalwork is challenging to treat. Negative pressure wound therapy (NPWT) with irrigation is an emerging therapy for infected wounds as an adjunct to antibiotic therapy. The senior author had devised a modified technique to augment its efficacy, utilising high-flow rate irrigation and skin closure over the standard NPWT dressing. This novel technique was originally evaluated in a different centre and produced 100% success in metalwork retention. The present study is a reproducibility test of the same technique.

Methods A retrospective review was performed on 24 patients with infected orthopaedic metalwork, including 3 upper limb and 21 lower limb cases, for outcomes relating to implant retention and infection resolution. Patients underwent a modified NPWT technique as an adjunct to antibiotic therapy and surgical debridement. Detailed medical and microbiology information were obtained from the patient records.

Results 23 of 24 (96%) patients had successful metalwork retainment with healed wounds and resolution of infection, allowing fracture union. 27 infective organisms were identified in this cohort, and the antibiotic regimens for each patient are provided. The average follow-up was 663 days. No adverse effects were observed.

Conclusion This series supports the modified NPWT technique as a safe, reliable and effective adjunct therapy to resolve metalwork infection. The same results have been reproduced as the previous cohort in a different centre.

Abstract

Our objective was to determine current practice in Switzerland regarding the use of pNPWT in abdominal surgery. An online survey was carried out to evaluate the use of pNPWT among abdominal surgeons in Switzerland. One hundred and ten participants replied to the survey from 16.12.2019 to 15.01.2020. Eleven were excluded, leaving 99 responders for analysis. Seventy participants (70.7%) were using pNPWT, 3 (3%) have stopped using it and 26 (26.3%) have never used it. pNPWT was used on midline laparotomy by 63 responders (90%), closed stoma wounds by 21 (30%), closed perineal wounds by 20 (28.6%), Pfannenstiel incisions by 18 (23.7%), groin incisions by 16 (22.9%), subcostal incisions by 13 (18.6%), Mc Burney incisions by 3 (4.3%) and other incisions by 18 (25.7%). Forty-eight participants (68.6%) used pNPWT on less than 10% of patients, 14 (20%) on 10–25% of patients, six (8.6%) on 25–50% of patients and two (2.9%) on 75–100% of patients. Suggestions for improvement to pNPWT were: better sealing, recyclable system, better adaptation to the perineum, smaller device, reduced cost and possibility to check the surgical wound through the dressing. In conclusion, pNPWT is widely used among Swiss surgeons, mostly on midline incisions. However, most of them apply pNPWT on a small proportion of patients only. Suggestions for improvement were a better sealing for complex wounds, reduced cost and possibility to check the wound during the therapy.

Abstract

Background Wound infection after inguinal hernia surgery is not uncommon in the clinical setting. The common microbial aetiology of postoperative inguinal hernia wound infection is Gram-positive bacteria. Staphylococcus aureus is a common pathogen causing wound infection while Staphylococcus epidermidis and Pseudomonas are rare. Staphyococcus epidermidis as a cause of severe wound infection is rarely described in literature. We herein present a case of a 79-year-old man with a rare wound infection after bilateral inguinal herniorrhaphy caused by MRCNS (Methicillin Resistant Coagulase Negative Staphylococcus).

Case presentation We present a case of wound infection accompanied by fever with a temperature of 38.8 °C after bilateral inguinal herniorrhaphy in a 79-year-old man. Bilateral inguinal wounds were marked by redness and swelling, with skin necrosis. In addition, an abscess of approximately 1.5 cm×1.5 cm was seen on the left wrist. A small amount of gas under the skin in the wound area was observed after pelvic computed tomography (CT) scans. No bacteria were cultured from the inguinal wound discharge, while blood culture detected MRCNS, and Acinetobacter lwoffi was cultured from the pus in the left wrist. We chose appropriate antibiotics based on the results of the bacterial culture and the drug susceptibility results. Vacuum assisted closure (VAC) therapy was used after debridement. The patient was discharged after the wounds improved. He was followed up for ten months and showed no signs of complications. We are sharing our experience along with literature review.

Conclusions We are presenting a rare case of MRCNS wound infection following open inguinal hernia surgery. Although a rarity, clinicians performing inguinal hernia surgery must consider this entity in an infected wound and follow up the patient for complications of MRCNS.
