Purpose: To assess the efficacy and toxicity of salvage surgery for local or cervical nodal recurrence after accelerated radiotherapy for locally advanced head-and-neck squamous cell carcinoma (HNSCC).

Methods And Materials: We reviewed the medical records of the 136 patients with HNSCC who had been treated in three consecutive clinical trials at the Institut Gustave-Roussy using a very accelerated radiotherapy regimen (62 to 64 Gy with 2 daily fractions of 1.8 to 2 Gy over 3.5 weeks). Sixty-nine patients of the 136 initial patients (51%) had local or neck lymph nodes relapse, or both.

Results: Sixteen of these 69 patients (23%) had undergone salvage surgery for recurrence locally (n = 8) or in the cervical nodes (n = 8). All 16 had initially been diagnosed with locally advanced oropharyngeal carcinoma (T4, 11 patients; T3, 5 patients), and 13 had initially had cervical node involvement. After salvage surgery, 6 patients had had a local recurrence; 7, cervical node recurrence; and 3, distant metastasis. Thus, salvage surgery had been successful only in 3 patients. The 3- and 5-year overall actuarial survival rates were 20% and 11%, respectively. Eight patients had major postoperative wound complications, including carotid rupture in three cases.

Conclusion: Salvage surgery for relapse after very accelerated radiotherapy for advanced HNSCC is infrequently feasible and is of limited survival benefit. It should be used only in carefully selected cases.

Background: Limb-salvage surgery for malignant bone tumors can be associated with considerable perioperative blood loss. The aim of this randomized controlled trial was to assess the safety and efficacy of the intraoperative infusion of tranexamic acid (TXA) in children and adolescents undergoing limb-salvage surgery.

Methods: All participants were <18 years of age at the time of surgery and diagnosed with a malignant bone tumor of the femur that was treated with resection and reconstruction with a megaprosthesis.

Osteonecrosis of femoral head (ONFH) can be a debilitating disease, for which numerous salvage surgeries have been popularized to halt its progression. The aim of this study was to assess the clinical and radiological outcomes of a single-incision core decompression (CD) technique using trochanteric autograft in ONFH and to determine the prognostic factors of treatment success. Sixty-six hips (41 patients) of Association Research Circulation (ARCO) 1 and 2 ONFH undergoing CD were included in the study with a mean follow-up of 58 months.

Background: Breast reconstruction with the deep inferior epigastric perforator (DIEP) free flap has become the gold standard for autologous breast reconstruction. Flap take-back to the operating room (OR) is an uncommon but difficult situation, requiring prompt and accessible resources. We conducted a literature review and independent expert review to inform evidence-based perioperative algorithms in the event of DIEP flap compromise.

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.

Background: ABO-incompatible liver transplantation (ABOi LT) can now be successfully performed with standard pretransplant induction therapy. For patients with chronic end-stage liver disease (ESLD), ABOi LT can achieve long-term outcomes comparable to those of blood type-compatible (ABOc) LT. Outcomes of patients with acute liver failure (ALF) who undergo urgent transplantation surgery with a limited induction period should be further investigated.
