Adenoid cystic carcinoma of the head and neck area is a rare malignant tumor with acceptable short-term but mediocre long-term prognosis. Radical tumor excision with clear resection margins, and sometimes resection of the facial nerve due to perineural growth, remains the fundamental therapy. We present 3 distinct clinical cases and discuss the current therapeutic options with special focus on plastic-reconstructive techniques. For reconstruction, the full armament of local and free flaps, as well as prosthetics, may be necessary...

Robot-assisted radical cystectomy (RARC) has been adopted widely in many centres, owed largely to the success of robot-assisted laparoscopic prostatectomy (RALP). It aims to replicate the oncological outcomes of open radical cystectomy (ORC), while providing a shorter recovery period. Despite this, previous RCTs have failed to show a benefit for RARC over ORC. These trials have compared extracorporeal RARC (eRARC) with ORC, which requires a further incision to mobilise the bowel for urinary reconstruction with an open technique...

Soft tissue sarcoma of the forearm, wrist and hand are rare. Their benign appearance leads often to primary inadequate treatment. Due to the complex anatomy of the hand and forearm, they are challenging to treat. The two goals are to obtain wide resection of the primary tumor while preserving function. Limb-sparing surgery is now the cornerstone for the treatment of most sarcomas of the forearm, hand and wrist. To achieve optimal oncological and functional outcomes, the surgical excision should be associated with early reconstructive procedures and a multidisciplinary meeting to define the treatment strategy including adjuvant medical treatments...

The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG...

BACKGROUND: Older patients, especially those older than 65 years, are accounting for an ever-increasing share of hospital costs, especially surgical procedures. Studies regarding the safety of surgery in these patients have been widespread in the past decade. Despite these efforts, there is a paucity of information regarding the safety of reconstruction following spinal surgery in older patients. METHODS: We conducted a retrospective cohort study of patients undergoing soft-tissue reconstruction of the posterior trunk after oncologic spine surgery...

The main purpose of head and neck reconstructive surgery is to provide anatomic restoration of the demolited region and to provide preservation and recovery of function. The anatomical investigations conducted over the years has enabled a detailed knowledge of human body vascularization, giving the opportunity to design and harvest more and more versatile and refined flaps, with increasingly satisfactory results. Even if in the last 2 decades free flaps have been considered a reconstructive criterion standard, they still determine a great physical impact for the patient and require a certain surgical experience...

BACKGROUND: Poor prognosis of sinonasal cancers (SNC) is usually due to the non-specific symptoms leading to late diagnosis with locally advanced disease. However, previous prognostic studies were often based on heterogeneous cohorts because of the scarcity of SNC. With squamous cell carcinoma being the main histological subgroup, the study aimed to perform a prognostic analysis on sinonasal squamous cell carcinoma (SNSCC) particularly, and to evaluate the oncological results of a multimodal therapy...

INTRODUCTION: Laparoscopic techniques are commonly used in abdominal and gynecologic surgery, while breast cancer surgery has remained largely unchanged. In Asia, especially in Japan, many surgeons have started to use endoscopic surgery for breast cancer. In Taiwan, endoscopy-assisted breast surgery started in 2010. The benefits of this surgical method include smaller incisions, an axillary anatomic approach, clear vision, no oncologic compromise, and good cosmetic outcomes. This is the first report to discuss the learning curve of endoscopy-assisted breast surgery, including the difficulties experienced...

Calvarial defects are common reconstructive dilemmas secondary to a variety of etiologies including traumatic brain injury, cerebrovascular disease, oncologic resection, and congenital anomalies. Reconstruction of the calvarium is generally undertaken for the purposes of cerebral protection, contour restoration for psychosocial well-being, and normalization of neurological dysfunction frequently found in patients with massive cranial defects. Current methods for reconstruction using autologous grafts, allogeneic grafts, or alloplastic materials have significant drawbacks that are unique to each material...

The utilization of advanced imaging modalities play an important role in the detection and differentiation of benign and malignant hepatic lesions. Imaging characteristics of hepatic tumors can sometimes be atypical, often leading to diagnostic challenges. Recent technical improvements in contrast enhanced ultrasound (CEUS), computed tomography (CT), and magnetic resonance imaging (MRI) have helped to better characterize hepatic lesions. For example, contrast agents used in US can now better delineate liver lesions, while the ability to reliably produce multiplanar and 3-D reconstructions through the use of MDCT provides an additional advantage in the context of therapeutic decision making for patients with hepatic lesions...

BACKGROUND: Wilms tumors (WTs) are the most frequent renal tumors in children. Radical nephrectomy (RN) remains the gold-standard surgical treatment for this type of cancer. Excellent results in overall survival (>90%) make it possible to consider nephronic preservation. The objective of this systematic review is to evaluate the relevance of nephron-sparing surgery (NSS) for the treatment of nonsyndromic unilateral Wilms tumor (UWT) in children. METHODS: Articles in English related to "unilateral Wilms tumor, unilateral nephroblastoma, partial nephrectomy, nephron-sparing surgery, renal function" identified in the Medline library were screened and data were extracted to perform a qualitative systematic review...

BACKGROUND: Nipple sparing mastectomy (NSM) with immediate prosthetic reconstruction is routinely performed due to excellent aesthetic results, and safe oncologic outcomes. Typically, subpectoral expanders are placed, but in select patients, this can lead to significant postoperative pain and animation deformity, due to pectoralis major muscle disinsertion and stretch. Prepectoral reconstruction is a technique that eliminates dissection of the pectoralis major, by placing the prosthesis completely above the muscle with complete acellular dermal matrix (ADM) coverage...
