Background: The treatment of complex incisional hernias is still difficult and controversial. With technologic developments we can modify and update the operative techniques described for treating complex abdominal wall hernias.
Methods: This is a prospective study of 50 patients with complex incisional hernias undergoing complex abdominal wall herniorrhaphy at a university hospital. All patients were evaluated in a multidisciplinary clinic dedicated to abdominal wall reconstruction. All patients underwent pre-operative computed tomography. Complex incisional hernias were regarded as those with multiple recurrences (>3 times), a previous mesh complicated by fistula and chronic infection, giant diffuse lumbar hernias, an associated parastomal hernia, or hernias developing after bariatric surgery. The operative technique was a double reconstruction prosthetic mesh. The type of repair as well as clinical, operative, and follow-up data were analyzed.
Results: Eight patients had considerable loss of tissue, 5 had trophic skin lesions, and 2 had chronic suppurative infection. The mean size of the defects was 18.2 cm. Morbidity included 5 cases of seroma, 2 neuralgias, and 2 cutaneous necroses. The mean duration of hospital stay was 5 days (range, 2-9). Complete follow-up (mean, 48 months; range, 12-108) showed no recurrent hernias.
Conclusion: While awaiting a longer follow-up to confirm the results, we conclude that complex incisional hernias can be repaired safely and with a low morbidity and recurrence rate by means of a double prosthetic repair technique.

Background: Adult-type granulosa cell tumors are a rare form of ovarian cancer, 30% of which will recur. Cytoreductive surgery is often performed at the time of a first recurrence, but little is known about the impact of open versus minimally invasive surgical approaches on survival outcomes.
Objective: To examine associations between surgical approach, clinical variables, and survival outcomes among patients with adult-type granulosa cell tumors who underwent cytoreductive surgery at the time of first recurrence.
The management of locally advanced esophageal cancer typically involves esophagectomy; however, postoperative complications, particularly anastomotic stricture, remain prevalent. Anastomotic stricture can severely compromise patients' quality of life by leading to difficulties in food intake. Although endoscopic balloon dilation has become a standard treatment for gastrointestinal strictures, its efficacy is often limited due to the risk of perforation and the potential for recurrent stricture, necessitating multiple interventions.

Introduction: Nipple-sparing mastectomy (NSM) aims to improve patient satisfaction by preserving the nipple-areola complex (NAC) while ensuring oncologic safety. Different surgical incisions, such as inframammary fold (IMF) and periareolar/radial incisions, are used in NSM; however, their impact on NAC sensory loss remains unclear. In this study, the authors aimed to assess NAC sensation after NSM and compare the results of different incisional approaches, specifically IMF versus periareolar/radial.

Incisional hernia is a type of iatrogenic disease, and its clinical treatment is complicated. In recent years, there have been new advances in the diagnosis, surgical methods, and materials science of incisional hernias. On the basis of the , more than 70 experts and scholars over the country have discussed the consultation and modified the issues such as complex abdominal wall conditions, loss of domain, principles of incisional hernia treatment, techniques of abdominal wall hernia defects closure, perioperative management, and follow-up in this new edition, combined with evidence-based medical evaluation standards.

Small cell osteosarcoma (SCOS) is a rare variant of conventional osteosarcoma, characterized by tumor cells of small size and uniform morphology, which can lead to diagnostic confusion with other small cell tumors, requiring a detailed diagnostic approach. The manifestation in a child adds a degree of complexity, as the management of malignant tumours in paediatric patients requires specific considerations to minimize the long-term side effects of oncological treatment and preserve the structural and functional development of the orofacial region. This report concerns an 8-year-old female patient referred to the Oral and Maxillofacial Surgery outpatient clinic with progressive swelling in the right maxillofacial region, initially asymptomatic, but progressing to pain and difficulty chewing.
