BACKGROUND: Bowel dilatation is a common adaptive mechanism after intestinal resection. The symptomatic dilated dysmotile duodenum is difficult to manage, since conventional bowel tailoring and lengthening techniques are potentially hazardous because of the anatomy of the duodenal blood supply, the proximity to the pancreas, and the risk of injury to the common bile duct. METHODS: A 2-month-old child with short bowel and a symptomatic massively dilated duodenum was treated with a Transverse Flap Duodenoplasty (TFD)...

Percutaneous approaches to treat structural heart diseases are growing in number and complexity. Multimodality imaging is essential for planning and monitoring such interventions. The combination of three-dimensional transoesophageal echocardiography with fluoroscopy is the cornerstone of interventional imaging. However, these two modalities are displayed on separate screens, and are handled by different physicians, which requires a complex mental reconstruction for the interventional team. To overcome this issue, echocardiographic-fluoroscopic fusion imaging has been introduced recently in clinical practice...

We present an easy-to-use parametric image retouching method for thinning or fattening a face in a single portrait image while maintaining a close similarity to the source image. First, our method reconstructs a 3D face from the input face image using a morphable model. Second, according to the linear regression equation derived from the depth statistics of the soft tissue in the face and the user-set parameters of weight-change degree, we calculate the new positions of the feature points. The Laplacian deformation method is then used for non-feature points in the 3D face model...

BACKGROUND: Basal cell carcinomas (BCC) located in the sun-exposed regions are a serious therapeutic challenge. Therefore early diagnosis and adequate therapy should be of a high priority for every dermatologic surgeon. CASE PRESENTATION: We are presenting a patient with multiple BCCs, located on the area of the scalp, who had been treated several years ago with electrocautery and curettage after histopathological verification. However, the last few years the tumours have advanced, infiltrating firstly the tabula external and a year later the tabula interna of the cranium...

PURPOSE: Reconstruction of orbital wall fractures is demanding and has improved dramatically with the implementation of new technologies. True-to-original accuracy of reconstruction has been deemed essential for good clinical outcome, and reasons for unfavorable clinical outcome have been researched extensively. However, no detailed analysis on the influence of plate position and surface contour on clinical outcome has yet been published. MATERIALS AND METHODS: Data from a previous study were used for an ad-hoc analysis to identify predictors for unfavorable outcome, defined as diplopia or differences in globe height and/or globe projection of >2 mm...

BACKGROUND: Revision THA to treat recurrent instability can itself be complicated by recurrent instability, and when this occurs, this problem is difficult to treat. Some patients' THAs will continue to dislocate despite use of a constrained liner. One option in this difficult-to-treat group is conversion to a dual-mobility (DM) construct, but there are few data on this approach. QUESTIONS/PURPOSES: (1) What were the Harris hip scores in a small group of patients whose constrained liners were converted to DM constructs to treat recurrent dislocation? (2) What were the redislocation, rerevision, and DM construct retention rates in these patients? METHODS: We conducted a retrospective analysis of a longitudinally maintained institutional database maintained by individuals other than the treating surgeons to identify patients undergoing conversion of constrained liners to DM constructs in revision THA from 2011 to 2014...

BACKGROUND: When a small, thin, and durable flap is required for coverage of the foot, the proximal peroneal artery perforator (PPAP) free flap may be a novel option. However, few clinical results and anatomical studies on the PPAP flap have been published. METHODS: A total of 24 PPAP flaps used in 22 patients from January 2013 to December 2016 were analyzed. All flaps were elevated in the subfascial plane based on a single perforator from the peroneal artery between the soleus and peroneus muscles...

INTRODUCTION: Medial canthus is a common area of skin cancer prevalence. Defects in this region represent a challenging reconstructive task. The nasal version of keystone perforator island flap (KPIF) has proven its versatility. The aim of the present study was to expand its utilization in the neighbor medial canthus area. A modified croissant-like KPIF (CKPIF) was used resolving inner convexity-related problems. The presence of procerus in the glabella area, bridging a surface from nasalis up to the frontalis, changed the traditional dissecting flap technique...

BACKGROUND: Bony defect situations are a common problem in revision arthroplasty of the shoulder and are the cause of the complexity of the procedure. Aseptic and septic loosening as well as difficult implant removal can result in humeral and/or glenoid bone loss. PLANNING: A careful preoperative imaging is needed to estimate the extent of the bony defect and to enable precise planning of the bone reconstruction and the required implants. However, the size of the defect needs to be re-evaluated intraoperatively after removal of the implant components and any larger defects have to be addressed appropriately...
