Comparison between endoscopic and open surgery in 37 patients with nasopharyngeal angiofibroma

Juvenile nasopharyngeal angiofibroma is a rare benign vascular tumor of the nasopharynx. Although the treatment of choice is surgery, there is no consensus on what is the best approach. Aim: To compare surgical time and intraoperative transfusion requirements in patients undergoing endoscopic surgery versus open / combined and relate the need for transfusion during surgery with the time between embolization and surgery. Material and Methods: Study descriptive, analytical, retrospective study with a quantitative approach developed in the Otorhinolaryngology department of a teaching hospital. Analyzed 37 patients with angiofibroma undergoing surgical treatment. Data obtained from medical records. Analyzed with tests of the Fisher-Freeman-Halton and Games-Howell. Was considered significant if p <0.05. Study design: Historical cohort study with cross-sectional. Results: The endoscopic approach had a shorter operative time (p <0.0001). There is less need for transfusion during surgery when the embolization was performed on the fourth day. Conclusion: This suggests that the period ahead would be ideal to perform the process of embolization and endoscopic surgery by demanding less time would be associated with a lower morbidity. This study, however, failed to show which group of patients according to tumor stage would benefit from specific technical.

Levothyroxine Absorption in Morbidly Obese Patients Before and After Roux-En-Y Gastric Bypass (RYGB) Surgery

Roux-en-Y gastric bypass (RYGB) modifies the anatomical structure of the upper intestine tract, reduces gastric acid secretion, and may impair LT4 absorption. The aim of this study was to evaluate the LT4 absorption in morbidly obese patients before and after RYGB. Thirty morbidly obese patients were divided in two groups: The NS group included 15 patients before RYGB surgery (BMI = 43.1 +/- 4 kg/m(2)), and the S group included 15 patients after surgery (BMI = 37.3 +/- 4 kg/m(2)). Two baseline samples were collected, and 600 mu g of oral LT4 tablets were administered. Blood samples were collected at 30, 60, 120, 180, 240, 300, and 1440 min. Serum-free T4 (FT4), total T4 (TT4), and TSH were measured at each time point. The increase in TT4, FT4, and TSH (Delta TT4, Delta FT4, and Delta TSH) was calculated, subtracting from the baseline mean value. The pharmacokinetics parameters regarding LT4 absorption, maximum Delta TT4, and area under the curve(AUC) of both Delta TT4 and Delta FT4 were significantly higher in the S group compared with the NS group (p < 0.05). It was observed, however, that there was a significant delay in the absorption of LT4 in the S group. Basal serum TSH and leptin levels were higher in the NS group (p = 0.016 and 0.026, respectively), whereas basal serum TT4, FT4, Delta TSH, and the AUC of Delta TSH were similar between groups. In this study, we have demonstrated that Roux-en-Y bypass surgery does not diminish LT4 absorption. A small but significant delayed absorption of LT4, however, was observed in patients after surgery.
