Robotic nipple-sparing mastectomy complication rate compared to traditional nipple-sparing mastectomy: a systematic review and meta-analysis.

Breast cancer is worldwide the most common cause of cancer in women and causes the second most common cancer-related death. Nipple-sparing mastectomy (NSM) is commonly used in therapeutic and prophylactic settings. Furthermore, (preventive) mastectomies are, besides complications, also associated with psychological and cosmetic consequences. Robotic NSM (RNSM) allows for better visualization of the planes and reducing the invasiveness. The aim of this study was to compare the postoperative complication rate of RNSM to NSM. A systematic search was performed on all (R)NSM articles. The primary outcome was determining the overall postoperative complication rate of traditional NSM and RNSM. Secondary outcomes were comparing the specific postoperative complication rates: implant loss, hematoma, (flap)necrosis, infection, and seroma. Forty-nine studies containing 13,886 cases of (R)NSM were included. No statistically significant differences were found regarding postoperative complications (RNSM 3.9%, NSM 7.0%, p = 0.070), postoperative implant loss (RNSM 4.1%, NSM 3.2%, p = 0.523), hematomas (RNSM 4.3%, NSM 2.0%, p = 0.059), necrosis (RNSM 4.3%, NSM 7.4%, p = 0.230), infection (RNSM 8.3%, NSM 4.0%, p = 0.054) or seromas (RNSM 3.0%, NSM 2.0%, p = 0.421). Overall, there are no statistically significant differences in complication rates between NSM and RNSM.

Traumatic hemipelvectomy: Improvements in the last decennia illustrated by 2 case reports.

INTRODUCTION: In this article we present two cases of young men who sustained a traumatic hemipelvectomy. PRESENTATION OF CASE: The first case occurred more than 10 years ago and the second case happened less than 1 year ago. Changes in the management for resuscitation, surgical intervention, and in postoperative treatment are detailed. Goal of this article is to evaluate the changes over time in the treatment of trauma in general and this specific injury in particular. DISCUSSION: Maximum survival chance could be achieved by an aggressive resuscitation (following a massive transfusion protocol-ratio of 1:1:1 unit of blood-products), starting pre-hospitally and continued in the emergency department, immediate control of the haemorrhage and direct surgical intervention. Early and frequent re-explorations are necessary to prevent complications as sepsis and to minimize the chance for complications such as disturbed wound healing and fistula formation. The use of the Vacuum-Assisted Closure therapy nowadays gives the patient an earlier recover and lesser chance at developing complications. Early consultation with plastic surgeons needs to be done in order to achieve an adequate definitive wound-closure (reconstructive surgery). CONCLUSION: A traumatic hemipelvectomy is a catastrophic and mutilating injury, seldom survivable. Maximum survival chance could be achieved by an aggressive resuscitation, frequent re-explorations, the use of VAC therapy and early consultation with a plastic surgeon for reconstructive surgery.

Corrugator supercilii transection for headache emanating from the frontal region: a clinical evaluation of ten patients.

Chronic daily headache (CDH) located in the frontal region is a common problem. We have previously described the positive results that were achieved with botulinum toxin (BTX) injections in the musculus corrugator supercilii (MCS) for this disorder. Nowadays, we offer transection of this muscle to patients following a minimum of two BTX injections, provided these injections result in a significant reduction of pain. This procedure is based on the assumption that the pathophysiological mechanism in some of these patients suffering from CDH is a neural entrapment of the supratrochlear nerve in the corrugator muscle. To assess the effect of transection, we have evaluated all the consecutive patients (n = 10) so far. Treatment was successful in nine of these patients. Prior to the treatment, the mean pain score in the 9 successfully treated patients was 8.1 (range 6-9), after transection this had been reduced to 0.8 (range 0-3). All of these successfully treated patients ceased their daily use of pain relief medication for their frontally localised headaches. Moreover, they stated that they would definitely undergo surgery, if they were to find themselves in the same situation again. Therefore, we conclude that transection of the MCS is an efficient and successful procedure for a carefully selected group of patients suffering from CDH in the frontal region. Most of all we intend to popularise this pathophysiological concept based on the distinct possibility that some headaches might be due to neural entrapment.

The prognostic value of abnormal findings on radiographic swallowing studies after total laryngectomy.

Pharyngocutaneous fistulae are a common complication after total laryngectomy. Our study evaluates the correlation of postoperative radiographic swallowing studies and clinical symptoms. We also propose a grading system to classify leaks radiographically. The records of 45 patients who underwent total laryngectomy were retrospectively reviewed. All patients had a radiographic swallowing study (RSS) on or around the tenth postoperative day. A grading system was developed to classify radiographic findings (grade 0-5). Twenty-two patients had an abnormal RSS (grade 2-5). Three patients (13.6%) had clinical signs of impending fistula whereas radiography showed moderate leakage (grade 3) in one patient and a pharyngocutaneous fistula (grade 5) in two. The other 19 patients with radiographically demonstrated leakage had no clinical signs of anastomotic complications. After total laryngectomy, radiography may reveal anastomotic complications of varying severity. The grading system used in this study enabled us to objectively classify the radiological abnormalities on swallowing studies. Because most radiographic leakages were clinically silent and not all clinically apparent fistula were radiographically visible in our study, the role of routine postoperative radiographic swallowing studies in the absence of clinical signs or fistula remains unclear.

Intraparotid facial nerve schwannoma. What to do?

An intraparotid facial nerve schwannoma is often not recognised in pre-treatment work-up and frequently results in subsequent significant postoperative morbidity. We have evaluated the literature regarding pre-treatment work-up and facial nerve function outcome. Two of our own cases are presented. A minority of the intraparotid schwannomas can be removed by resection while preserving facial nerve integrity and function. In the event of preoperative facial nerve dysfunction, tumour resection and subsequent nerve repair should be considered. If resection of an intraparotid facial nerve schwannoma cannot be performed with preservation of facial nerve integrity and function, a wait-and-see policy seems justified due to the indolent behaviour of the tumour and moderate results of facial nerve reconstruction.

[Adverse effects if smoking on healing of bones and soft tissues]. / Rauchen ist nachteilig für die Heilung von Knochen und Weichteilen.

This article reviews the current body of knowledge on the adverse effects of smoking on soft-tissue and bone healing, with emphasis on tibial fractures in combination with severe soft-tissue injury. The pathophysiological effects are multidimensional, including arteriolar vasoconstriction, cellular hypoxia, demineralisation of bone, and delayed revascularisation. Several animal and clinical studies have been published about the negative effects of smoking on bone metabolism and fracture healing. These studies show that smokers have a significantly longer time to clinical union than non-smokers and a higher incidence of non-union. The negative effects of smoking gained increased interest among plastic and microvascular surgeons, because smokers have been shown to suffer higher rates of flap failure, tissue necrosis, and haematoma formation. Especially smokers presenting with an open tibial fracture will suffer the negative effects of their smoking behaviour, because these fractures are inextricably bound up with soft-tissue injury. Their fractures will need a significantly longer time to heal than in non-smokers, and will have a higher incidence of non-union. If microvascular surgery is to be performed, persistent smoking significantly increases the rate of postoperative complications, with wound infection, partial flap necrosis, and skin graft loss being more common. Cessation of smoking has both short- and long-term beneficial effects. Nowadays, there is strong evidence to be very insistent that patients presenting with a (open) tibial fracture should refrain from smoking immediately to promote bone healing and to lower the complication rate. In case of elective reconstructive procedures, patients should refrain from smoking at least 4 weeks before surgery. In both situations, cessation should continue during the full rehabilitation period.
