Background: The establishment of preoperative chemotherapy (PCT) with FOLFIRINOX and gemcitabine/nab-paclitaxel in recent years has enabled resectability in many patients with initially locally advanced pancreatic cancer (LAPC). Nevertheless, information about the impact of PCT on surgical results is scarce.
Methods: All patients with initial LAPC who received surgery after chemotherapy at the high-volume centre for pancreatic surgery of St. Josef-Hospital Bochum between 2015 and 2022 were included in this retrospective cohort analysis.
Results: A total of 139 patients underwent surgery after pre-treatment with FOLFIRINOX (76.3%), gemcitabine/nab-paclitaxel (11.5%), both (5.8%) and other regimens (6.5%). Eighty-five tumors (61.2%) were resectable after PCT. R0 resection was achieved in 92.9%, R1 in 7.1% and R2 in 0% of cases. Fifty-four tumors were still not resectable at the time of surgery. Surgical results of the patients did not show increased postoperative mortality and morbidity compared to the literature data. Postoperative 30-day mortality was 1.4%. Rates for pancreas-specific complications [postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), and others] were not increased. POPF occurred in 10.5% and DGE in 26.3% after pancreaticoduodenectomy. After distal pancreatectomy, POPF was detected in 37.5% and DGE in 12.5%. Median postoperative survival (31 13 months) and overall survival after initial diagnosis (40 20 months) were significantly longer in resected patients (P<0.001). Postoperative recurrence-free survival in resected patients amounted to 12 months.
Conclusions: This study underlines that PCT allows resectability of primarily unresectable patients with LAPC without increasing perioperative mortality and morbidity. It may lead to a significant prolongation of recurrence-free and overall survival in resected patients after PCT.

The objectives were to evaluate the effectiveness and safety of a single preoperative dose of intravenous tranexamic acid (TXA) in reducing perioperative blood loss and requirement for transfusion in patients undergoing hip hemiarthroplasty for femoral neck fracture. A double-blind randomized controlled trial was conducted in 140 patients with hip fracture. After randomization, 68 patients received a single dose of 1 gr of intravenous TXA at the start of the surgery (TXA group), and 72 received a placebo treatment (placebo group).

Introduction: Low grade appendiceal mucinous neoplasms (LAMN) are indolent tumors that lack invasive potential but may present as pseudomyxoma peritonei. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) significantly improves both overall and recurrence free survival. While systemic chemotherapy is generally considered ineffective for LAMN, little literature is available to support this notion.

Although osteosarcomas are the most frequent primary malignant bone tumors, the primary cranial manifestation of this condition is very rare with only a limited number of cases presented in the literature. We present the case of a 20-year-old male patient who underwent single-session surgical intervention for resection of right frontal osteosarcoma with a tailor-made craniotomy and cranioplasty using virtually designed 3D-printed templates and molds. Subsequently, the patient was treated according to the EURAMOS protocol and received adjuvant systemic chemotherapy.

General anaesthesia (GA) as a pharmacological behaviour management strategy may be indicated for dental extractions in children unable to cooperate in the dental chair. Pain is the most common postoperative complication in children following dental GA. There is conflicting evidence available on the efficacy of local anaesthetic (LA) agents for postoperative pain management following dental extraction.

Background: Sturge-Weber syndrome (SWS) is a rare congenital neurocutaneous disorder, often complicated by epilepsy. Approximately 50% of patients with SWS with epilepsy develop drug-resistant seizures, leaving limited treatment options. Vagus nerve stimulation (VNS) is a known therapy for refractory epilepsy, modulating neural activity to reduce seizures.
