Abstract

      Background Surgical site infections (SSI) in the groin after vascular surgery are common. The aim of the study was to evaluate the effect of negative pressure wound therapy (NPWT) on SSI incidence when applied on closed inguinal incisions after endovascular aneurysm repair (EVAR).

      Methods A multicenter randomized controlled trial (RCT). Between November 2013 and December 2020, 377 incisions (336 bilateral and 41 unilateral) from elective EVAR procedures with the primary intent of fascia closure were randomized and included, receiving either NPWT or a standard dressing. In bilateral incisions, each incision randomly received the opposite dressing of the other side, thereby becoming each other’s control. The primary endpoint was SSI incidence at 90 days postoperatively, analyzed on an intention-to-treat basis. Uni and bilaterally operated incisions were analyzed separately, and their respective p-values combined using Fisher’s method for combining P-values. Study protocol (NCT01913132).

      Results The SSI incidence at 90 days postoperatively in bilateral incisions was 1.8% (n = 3/168) in the NPWT and 4.8% (n = 8/168) in the standard dressing group, and in unilateral incisions 13.3% (n = 2/15) and 11.5% (n = 3/26), respectively (combined p = 0.49). In all SSIs, bacteria were isolated from incisional wound cultures. No additional SSIs were diagnosed between 90 days and 1 year follow-up. Conclusions No evidence of difference in SSI incidence was seen in these low-risk inguinal incisions when comparing NPWT with standard dressings after EVAR with the primary intent of fascia closure.

Clinical Trials: NCT01913132.

Abstract

Background Sternal wound infection (SWI) post cardiac surgery remains an important cause of extra morbidity, mortality and cost. The objective was to identify risk factors for SWI in a cardiac centre in Eastern Saudi Arabia as part of the investigation into Surveillance variance in the local rates of SWI.

Methods We included cases and controls from a cross section of patients who underwent major cardiac surgery between 2017 and 2020 matched for age, sex and time of surgery. An explanatory logistic regression model was fitted to estimate the risk factors.

Results N=204 (51 cases and 153 controls matching ratio 1:3, from a source population of 985 patients). factors significantly associated with SWI in the final multivariate model: hospital stay OR (1.05, Cl 1.01–1.10), Graft Conduit BIMA versus No Graft OR (10.94, Cl 1.60–74.63), transfusion of both packed cells plus other blood products versus

no transfusion OR (3.53, Cl 93–13.44), HbA1c OR (1.09 Cl 0.84–1.41), BMI OR (1.25, Cl 1.04–1.50), perioperative blood

glucose OR (1.02, Cl 1.004–1.03), surgery time OR (1.19, Cl 1.00–1.58).

Conclusions The diverse aetiology, cross-disciplinary nature of SWI prevention, and despite improved prevention

and control practices, including related care bundles with their proven value, SWI remain a serious challenge in cardiac surgery. Multidisciplinary consensus guidelines are well overdue.

Abstract

Objectives This prospective observational study aimed to clarify the incidence and independent risk factors of wound infection after laparoscopic surgery for primary colonic and rectal cancer.

Methods A prospective surveillance of surgical site infection (SSI) was conducted in consecutive patients with primary colorectal cancer, who underwent elective laparoscopic surgery in a single comprehensive cancer center between 2005 and 2014. The outcomes of interest were the incidence and risk factors of wound infection.

Results In total, 3170 patients were enrolled in the study. The overall incidence of wound infection was 3.0%. The incidence of wound infection was significantly higher in rectal surgery than in colonic surgery (4.7 vs. 2.1%, p<0.001). In rectal surgery, independent risk factors for developing wound infection included abdominoperineal resection (p<0.001, odds ratio [OR]=11.4, 95% confidence interval [CI]: 5.04–24.8), body mass index (BMI)≥25 kg/m2 (p=0.041, OR=1.97, 95% CI, 1.03–3.76), and chemoradiotherapy (p=0.032, OR=2.18, 95% CI, 1.07–4.45). In laparoscopic colonic surgery, no significant risk factors were identified.

Conclusions Laparoscopic rectal surgery has a higher risk of wound infection than colonic surgery. Laparoscopic rectal surgery involving abdominoperineal resection, patients with higher BMI, and chemoradiotherapy requires careful observation in wound care and countermeasures against wound infection.

Abstract

Introduction The main objective of this study is to examine chronic pain and limping in relation to lower extremity and pelvic fracture location in addition to fracture combinations if multiple fractures are present on the same leg that have not been previously reported. We hypothesize that fracture pattern and location of lower extremity and pelvis fractures of multiple injured patients influence their long-term pain outcome.

Materials and methods Retrospective cohort study. Patients with treated multiple lower limb and pelvic fractures at a level 1 trauma center and followed up for at least 10 years postinjury were assessed. Lower leg pain subdivided into persistent, load-dependent and intermittent pain, as well as limping were recorded by using self-administered patient questionnaires and standardized physical examinations performed by a trauma surgeon. Descriptive statistics were used to present comparative measurements between groups.

Results Fifty-seven percent of patients (n=301) showed chronic lower limb pain 10 years postinjury. Ten percent of all patients with chronic pain displayed persistent pain, and here the most common fracture combination was tibial shaft fractures in combination with femoral shaft or proximal tibial fractures (13%). One hundred fifty-one patients reported load-dependent pain, with the most common fracture combinations being fractures of the foot in combination with femoral shaft fractures or distal tibial fractures (11%). One hundred twenty patients reported intermittent pain, with the most common fracture combinations involving the shaft of the tibia with either the femoral shaft or distal tibia (9%). Two hundred fifteen patients showed a persistent limp, and here the most common fractures were fractures of the femoral shaft (19%), tibial shaft (17%), and pelvis (15%).

Conclusions In multiple injured patients with lower extremity injuries, the combination of fractures and their location are critical factors in long-term outcome. Patients with chronic persistent or load-dependent pain often had underlying femoral shaft fractures in combination with joint fractures.
