During hyperthermic intraperitoneal chemotherapy (HIPEC), high intra-abdominal pressure (IAP) increases the penetration depth of chemotherapeutic agents. Cisplatin is one of the most commonly used chemotherapeutic agents during HIPEC, and nephrotoxicity is the most common adverse effect. In this study, we aimed to evaluate the relationship between IAP increase, cisplatin levels in the blood, and early complications.

To compare the short-term outcomes of atrial septal defect (ASD) repair via right axillary incision (RAI) versus median sternotomy (MS) in children.

Osteonecrosis of the femoral head (ONFH) is a challenging orthopedic condition that often leads to progressive joint destruction and disability. This study aims to simplfy the surgical tehniques and idealize the position of bone grafting for the repair of ONFH, and its preliminary clinical results were reported.​ METHODS: Anatomical studies were first conducted on four fresh frozen cadaveric specimens (8 hips). Arterial perfusion was performed to precisely investigate the medial femoral circumferential vessels supplying to the posterior greater intertrochanter. Based on the anatomical findings, vascularised posterior inter-trochanteric bone graft and the corresponding surgical instruments were meticulously designed to ensure accurate creation of the decompression tunnel and precise fitting of the bone graft​From August 2018 to August 2021, a total of 20 patients (24 hips) underwent the medial femoral circumferential vascularized posterior intertrochanteric bone grafting procedure at our institution. Clinical data, imaging findings, ARCO staging, and Harris hip scores were systematically collected. Intraoperative parameters, including operative time and blood loss, were also recorded. Postoperatively, patients were followed up for at least two years. Hip preservation failure was defined as a decrease in the Harris score, radiographic progression of ONFH, or the necessity for THA.​ RESULTS: The cadaveric study revealed that the deep branch of the medial femoral circumflex artery (MFCA) consistently gave rise to 2-3 branches supplying the posterior intertrochanteric bone. The first branch originated from the superior margin of the quadratus femoris attachment, and the remaining two branches were located beneath the quadratus femoris. The branches supplying the posterior intertrochanteric bone are carefully dissected and preserved, a 4-5cm long, 1.5-16 cm thick and deep bone graft is cut, which is used to improve the vascularization and mechanical stability within the osteonecrosis.​There are 20 patients (24 hips) prospectively enrolled, including 15 male patients (19 hips). The average postoperative followup duration was 24.2 ± 5.6 months. Four patients had to undergo THA due to disease progression, while the remaining 20 hips continued to be monitored. The final mean postoperative Harris hip score (HHS) was 75.1 ± 13.7. Among the 24 hips, 20 did not require THA, resulting in a hip preservation rate of 83%. Based on comprehensive evaluations of clinical function, symptoms, and radiographic findings, 71% of the hips were considered to have achieved successful hip preservation.​ CONCLUSIONS: The modified vascularized posterior intertrochanteric bone grafting is a simple yet effective hip - preserving surgical technique. It enables precise placement of the vascularized bone graft directly under the subchondral bone, and the good blood supply of the graft significantly promotes bone repair. This technique provides a simple，reliable and ideal graft position to repair the ONFH, the clinical outcomes seem to be related to the degree of femoral head collapse, with less favorable results associated with more severe collapse, its long term efficacy needs studied further.

Bronchobiliary fistula (BBF) is a rare but fatal disease. Due to its rarity, only a limited number of cases have been reported, leading to a lack of consensus on appropriate treatment strategies.

To compare the efficacy of Ganz approach and Kocher-Langenbeck (K-L) approach in Pipkin type IV femoral head fracture (FHF) with internal fixation.

Atrioesophageal fistula (AEF) is a rare yet highly lethal complication after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF). Efficient screening and prompt surgical intervention within a multidisciplinary framework are critical for improving survival.

Intra-abdominal abscesses are common post-operative complications, typically resolving with percutaneous drainage and antibiotics. Chronic, refractory abscesses persisting for years and progressing to mechanical bowel obstruction are exceedingly rare.

Elastic fixation represents a novel approach to managing Lisfranc injuries. This study aims to evaluate the clinical efficacy of elastic fixation for such injuries using imaging, clinical evaluation indices, and plantar pressure analysis.

Colorectal cancer is among the most common global malignancies. Approximately 25% of patients present with liver metastases at diagnosis. Debate persists over whether to choose simultaneous or staged resection due to the varying evidence regarding outcomes and patient eligibility criteria for each approach. This study aims to assess and compare both short- and long-term surgical outcomes of simultaneous and staged resection approaches.

Pineoblastoma, a highly aggressive embryonal tumor predominantly affecting the pediatric population, poses significant therapeutic challenges. Current treatment modalities typically involve a combination of surgical resection, chemotherapy, and radiotherapy. While the clinical presentation of pineoblastoma is well-documented, its association with other neurological conditions, particularly Chiari malformations, remains exceedingly rare.

Copper deficiency is an under-recognized complication after metabolic and bariatric surgery (MBS) with hematologic and neurologic sequelae. Comparative evidence between one-anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) is limited. We compared time-dependent copper trends and deficiency prevalence after OAGB versus RYGB and identified associated factors.

The postoperative conversion of a protective stoma to a permanent stoma (PS) during sphincter-preserving surgery for rectal cancer can significantly impact the patient’s quality of life. No reliable tools exist to predict the likelihood of a protective stoma becoming permanent in clinical practice. This study aimed to develop an online, dynamic nomogram for predicting PS using multicenter, large-sample data.

Postoperative intra-abdominal abscesses (IAA) remain a significant complication after laparoscopic appendectomy for acute appendicitis. This study investigates the roles of the 5-item modified Frailty Index (mFI-5) and Inflammatory Burden Index (IBI) in predicting IAA risk.

Intraoperative red blood cell (RBC) transfusion strategies vary depending on multiple factors. Several studies have documented significant variability in RBC transfusion practices during surgery. This scoping review aimed to identify and describe existing criteria or clinical decision-making tools used to evaluate intraoperative and immediate post-operative RBC transfusion appropriateness.

Post-thyroidectomy airway complications, though rare, can be life-threatening. We present a case of acute airway compromise due to a combined tracheal fistula and critical stenosis in a patient with a history of giant goiter, successfully managed through multidisciplinary collaboration and awake fiberoptic intubation.

Free perforation of stomach or colorectum usually necessitates emergency surgery. Perforation is associated with short-term mortality and morbidity in up to 30% and 50% of patients, respectively, due to secondary peritonitis and sepsis. We hypothesized that postoperative clinical outcomes after colorectal perforation (CRP) are worse than those with stomach perforation (SP). This retrospective study aimed to compare the early postoperative clinical outcomes of patients with stomach and colorectal perforations, focusing on morbidity and mortality, and identify differences that could indicate potential changes in surgical management.
