Complex tracheal lesion: correction with an intercostal muscle pedicle flap.

Esophageal reconstruction is one of the most complex types of gastrointestinal surgery, principally when it is performed using minimally invasive techniques. The procedure is associated with various complications, such as anastomotic dehiscence, chylothorax, esophageal necrosis and fistulae. We report the case of a patient diagnosed with epidermoid carcinoma in the distal third of the esophagus.

Total gastrectomy with substitution of stomach by jejunal pouch with and without duodenal passage. Study in rats.

Purpose: A comparison was done between the F. Paulino jejunal pouch (FP) and a jejunal pouch (JP) as esophagus-duodenum interpositional graft, for replacing the stomach after total gastrectomy. It was investigated the effect of the two procedures on esophagus histology, nutritional state and serum gastrin in rats.

[Effects of endoscopic sympathicotomy in carotid and vertebral arteries in the surgical treatment of primary hyperhidrosis].

Purposes: Analyze, in patients with primary hyperhidrosis (PH) who was undergone to videothoracoscopic sympathicotomy, the degree of vascular denervation after surgical transection of the thoracic sympathetic chain by measuring ultrasonografic parameters in carotid and vertebral arteries.

Methods: Twenty-four patients with PH underwent forty-eight endoscopic thoracic sympathicotomy and were evaluated by duplex eco-Doppler measuring systolic peak velocity (SPV), diastolic peak velocity (DPV), pulsatility index (PI) and resistivity index (RI) in bilateral common, internal and external carotids, besides bilateral vertebral arteries. The exams were performed before operations and a month later.
