Background: Negative Pressure Wound Therapy (NPWT) is a therapeutic technique of applying sub-atmospheric pressure to a wound to reduce inflammation, manage exudate, and promote the formation of granulation tissue. It aims to optimise the natural physiological processes of wound healing for more effective recovery, and NPWT has emerged as a promising alternative to traditional dressings.
Methods: The protocol followed in the study was prospectively registered. Appropriate search terms and Boolean operators were used to search electronic databases for relevant articles. Screening of articles was performed, and data extraction was done. The effect measure was chosen according to the nature of the variable, and the effect model was chosen as per heterogeneity. Forest plot was used to give visual feedback.
Results: This study included 11 randomized controlled trials (13 publications) with a total of 1310 patients (1497 inguinal wounds). The NPWT group had lesser odds of developing surgical site infection (OR: 0.40; 95 % CI: 0.29-0.54; = 1491; I = 20 %; -value ≤0.00001) and lesser odds of needing surgical wound revision (OR: 0.48; 95 % CI: 0.26-0.91; = 856; I = 0 %; p-value = 0.02) as compared to the normal dressing group. No significant difference was observed in duration of hospital stay, cost of care, wound healing time, or other complications.
Conclusion: NPWT application in inguinal wounds significantly reduces the surgical site infection and the need for wound revision in patients who have undergone vascular surgery.

Purpose: To evaluate outcomes in patients aged ≥ 80 years following large-bore aspiration thrombectomy (LBAT) for the treatment of pulmonary embolism (PE).
Materials And Methods: All patients ≥ 80 years of age with PE treated via LBAT at a single center were analyzed from September 2019 - August 2024. This included the octogenarian subgroup from a recently published retrospective analysis assessing all PE patients treated with LBAT at our center between September 2019 and January 2023.
Freehand Apple-peeling Technique for Recycled Skin Graft Harvesting in a Case of Buttock Hidradenitis Suppurativa.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder that often necessitates extensive surgery when medical treatment fails, particularly in advanced stages. Traditional surgical approaches, including flaps and skin grafts, are effective for tissue coverage but can lead to vascular complications and recurrence of HS. This study introduces a novel technique, the apple-peeling procedure, combined with negative pressure wound therapy at -50 mm Hg for 5 days postoperatively.

Background And Objective: Diabetic neuropathy significantly elevates the risk of foot ulceration and lower-limb amputation, underscoring the need for precise assessment of tissue perfusion to optimize management. This narrative review explores the intricate relationship between sympathetic nerves and tissue perfusion in diabetic neuropathy, highlighting the important role of autonomic neuropathy in blood flow dynamics and subsequent compromises in tissue perfusion. The consequences extend to the development of diabetic peripheral neuropathy and related foot complications.

Protective ventilation reduces ventilator-induced acute lung injury postoperatively; however, the optimal strategy for one-lung ventilation (OLV) remains unclear. This study compared three protective ventilation strategies with a postoperative partial pressure of oxygen (PaO)/fraction of inspired oxygen (FiO) ratio to reduce the incidence of immediate postoperative pulmonary complications (PPCs) in patients undergoing lung resection surgery. Eighty-seven patients with ASA physical status I-III requiring OLV for lung resection surgery were randomized into three groups according to the applied ventilation strategies: low tidal volume (V) of 4 mL/kg of predicted body weight (PBW) (LV group), medium V of 6 mL/kg of PBW (MV group), and high V of 8 mL/kg of PBW (HV group).

To investigate the feasibility and clinical efficacy of a novel approach to managing the incisions used to treat tibial plateau fractures (TPFs) with soft tissue swelling. We retrospectively enrolled 64 patients with TPFs who underwent surgery at the Second Hospital of Shandong University. Patients were divided into two groups: Group A (n = 32) underwent early surgery with the novel incision management technique, and Group B (n = 32) underwent conventional surgery after swelling reduction.
