Zenker’s diverticulum: flexible versus rigid repair

Flexible band versus rigid ring annuloplasty for functional tricuspid regurgitation

We review and compare our experience with tricuspid ring annuloplasty between usage of the Cosgrove-Edwards flexible band and the MC(3) rigid ring for repair of functional tricuspid regurgitation to determine the efficacy and mid-term durability of tricuspid annuloplasty. 117 patients with functional tricuspid regurgitation undergoing open heart surgery and tricuspid valve repair from May 2005 ...

Transoral Flexible Endoscopic Therapy of Zenker's Diverticulum

can also be performed without the use of general anesthesia in many instances. A transoral flexible endoscopic approach successfully reduces cricopharyngeal sphincter pressure [6] . The septum can be divided with a variety of cutting instruments and accessories. It is unknown whether a transoral flexible endoscopic approach will show longterm results compared to rigid surgical therapy for long-...

QFT Control of a Two-Link Rigid-Flexible Manipulator

This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...

Delayed Primary Repair of Perforated Epiphrenic Diverticulum

A 68-yr-old man complaining of sudden, postprandial chest pain visited the emergency room. His symptom had been aggravated during the preceding two days. Upper gastrointestinal contrast study with gastrographin showed leakage of dye from the epiphrenic diverticulum in the lower third of the esophagus. The primary repair was urgently carried out. Upper gastrointestinal contrast study 14 days aft...
