BACKGROUND: The technique of thyroidectomy mandates adequate visualization of the operative field to identify pertinent anatomical structures. The purpose of this prospective review was to assess the feasibility and safety of endoscopic thyroidectomy by a cervical approach. METHODS: All patients who underwent endoscopic thyroidectomy were assessed by retrospective review of a prospective database. RESULTS: Thirty-eight patients underwent endoscopic thyroidectomy by a cervical approach. Thirty-five of 38 cases were successfully completed endoscopically with a mean OR time of 190 min. One patient experienced a permanent recurrent laryngeal palsy. CONCLUSION: Endoscopic thyroidectomy by a cervical approach is a feasible procedure. As in conventional thyroid surgery, great care should be exercised when dissecting the recurrent laryngeal nerve.
A major obstacle in the race to develop two-photon fluorescence endoscopy is the use of complicated bulk optics to transmit an ultrashort-pulsed laser beam and return the emitted fluorescence signal. We describe an all-fiber two-photon fluorescence microendoscope based on a single-mode optical fiber coupler, a microprism, and a gradient-index rod lens. It is found that the new endoscope exhibits an axial resolution of 3.2 microm and is capable of imaging transverse cross sections of internal cylindrical structures as small as approximately 3.0 mm in diameter. This device demonstrates the potential for developing a real-time diagnostic tool for biomedical research without the need for surgical biopsy and may find applications in photodynamic therapy, microsurgery, and early cancer detection.
We report a case of a mediastinal pseudocyst with a pleural effusion that developed in a patient suffering from alcohol- related chronic pancreatitis. A 53-year-old man was admitted to another institution complaining of pleuritic chest pain and coughing. A chest X-ray revealed a pleural effusion with a collapse of the right middle and lower lobes. Pleural fluid taken by thoracentesis was exudative, and the patient was transferred to our institution. A CT scan showed a loculated cystic lesion in the mediastinum and pancreatic changes that were consistent with chronic pancreatitis. The endoscopic retrograde cholangiopancreatography (ERCP) findings were compatible with chronic pancreatitis showing severe pancreatic ductal stricture at the head with an upstream dilation and distal bile duct stricture. After a one week of treatment with fasting and octreotide without improvement, both pancreatic and biliary stents were placed endoscopically. After stenting, the pleural effusion and pseudocyst rapidly resolved. The stents were changed 3 months later, at which time a repeated CT demonstrated a complete resolution of the pseudocyst. Since the initial stenting, he has been followed up for 7 months and is doing well with no recurrence of the symptoms, but he will need to undergo regular stent changes. Overall, endoscopic pancreatic stenting appears to be a good option for managing selected cases of mediastinal pancreatic pseudocysts.
