Over the past 10 years, robotic technology has had a significant impact on minimally invasive surgery. Because plastic surgery is rooted in "open" techniques, robotic applications in the specialty have been slow to emerge. That said, robotic technology possesses superhuman precision and high-definition, three-dimensional optics that are promising attributes in the hands of the plastic surgeon. In this article, the author explores three applications in robotic plastic surgery: (1) transoral robotic reconstructive surgery for head and neck reconstruction, permitting complex oropharyngeal reconstruction without dividing the lip or mandible; (2) robotic muscle harvest, permitting minimally invasive harvest of the latissimus dorsi and rectus abdominis muscle; and (3) robotic microanastomoses, extending the capabilities of the human hand in microvascular and microlymphatic surgery...

Transanal hemorrhoidal dearterialization (THD) is a relatively new, minimally invasive approach for the treatment of hemorrhoid disease. Despite increasing use of this procedure, there remains scarce United States-based data on the perioperative variables affected by this surgical technique. This article details the experience with THD at a single institution. This is a single-institution study that includes consecutive patients that underwent THD at George Washington University from November 2011 to April 2014...

To evaluate the influence of timing of open conversion on short-term and oncologic outcomes after minimally invasive surgery for colorectal cancer. Six hundred forty-six consecutive patients were enrolled. All patients converted to open surgery were classified into early (n = 10) or late (n = 67) groups based on conversion timing using a 60-minute cutoff. A comparison of early conversion and nonconverted groups showed that history of prior abdominal surgery and pT4 tumor was more common in the early conversion group...

Rolling mechanical imaging (RMI) is a novel technique towards the detection and quantification of malignant tissue in locations that are inaccessible to palpation during robotic minimally invasive surgery (MIS); the approach is shown to achieve results of higher precision than is possible using the human hand. Using a passive robotic manipulator, a lightweight and force sensitive wheeled probe is driven across the surface of tissue samples to collect continuous measurements of wheel-tissue dynamics. A color-coded map is then generated to visualize the stiffness distribution within the internal tissue structure...

Precise positioning of the target point during minimally invasive procedures is a major challenge associated with the use of image-based navigation systems. No significant dependence between fiducial registration error (FRE) and target registration error (TRE) was found. However, this investigation demonstrated the utility of using thin plate splines (TPS) and marker observation to monitor FRE during respiration to estimate target position based on the deformation field for minimally invasive procedures in deformable regions...

PURPOSE OF REVIEW: Ureteral duplication and ectopic upper pole ureters are commonly associated with renal pathology, including vesicoureteral reflux, obstruction, infection, and renal function loss. There remains no consensus on the most appropriate management of these complex patients. In this review, we sought to compare existing data on upper pole heminephrectomy with ipsilateral ureteroureterostomy. RECENT FINDINGS: Application of magnetic resonance imaging and minimally invasive techniques have led to changes in the diagnosis and treatment of ectopic upper pole ureters...

Dysregulation of neurochemicals, in particular, dopamine, is epitomized in numerous debilitating disorders that impair normal movement and mood aspects of our everyday behavior. Neurochemical transmission is a neuron-specific process, and further exhibits region-specific signaling in the brain. Tools are needed to monitor the heterogeneous spatiotemporal dynamics of dopamine neurotransmission without compromising the physiological processes of the neuronal environment. We developed neurochemical probes that are ten times smaller than any existing dopamine sensor, based on the size of the entire implanted shaft and its sensing tip...

The 2014 World Health Organization classification calls for endometrial mucinous proliferations that display "confluent or cribriform architecture with even minimal atypia" in sampling specimens to be classified as carcinoma, and others whose features are not diagnostic of carcinoma to be categorized as atypical mucinous glandular proliferations (AMGP). Herein, we evaluate follow-up findings in 41 cases that were classified as AMGP from our files. The average patient age was 46years (range 37-59). Post-biopsy follow-up duration ranged from 15-109weeks (mean 40)...

Diabetic cardiomyopathy (DCM) is a cardiac dysfunction which affects approximately 12% of diabetic patients, leading to overt heart failure and death. However, there is not an efficient and specific methodology for DCM diagnosis, possibly because molecular mechanisms are not fully elucidated, and it remains asymptomatic for many years. Also, DCM frequently coexists with other comorbidities such as hypertension, obesity, dyslipidemia, and vasculopathies. Thus, human DCM is not specifically identified after heart failure is established...
