Post-tonsillectomy morbidities: randomised, prospective controlled clinical trial of cold dissection versus thermal welding tonsillectomy.

BACKGROUND: New surgical techniques and devices have been described that decrease post-tonsillectomy morbidities. This study aimed to compare the two most popular tonsillectomy techniques. METHOD: Forty children underwent tonsillectomies using both the thermal welding and cold dissection techniques. In each patient, one side was removed with thermal welding and the other was removed with cold dissection. RESULTS: There was a significant decrease in intra-operative blood loss, and the mean operation time was significantly lower on the thermal welding side compared with the cold dissection side. On the cold dissection side, tissue healing (i.e. the rate of complete tissue healing) was better and less pain was reported compared with the thermal welding side. However, there were no significant differences between the two techniques in terms of throat pain scores on the 1st, 3rd or 14th day post-operatively, or tissue healing scores on any of the post-operative days assessed. CONCLUSION: Cold dissection resulted in better tissue healing and lower pain scores than thermal welding, but thermal welding was associated with less intra-operative blood loss and lower mean operation time than cold dissection.

Primary Intestinal-type Adenocarcinoma of the Nasal Cavity: A Case Report.

We report a rare case of sinonasal intestinal-type adenocarcinoma in the nasal cavity. A 31-year old man represented with headache and epistaxis. We identified a malignant tumour, which is a rare pathology, with detailed physical examination, anterior rhinoscopy, computed tomography scan, magnetic resonance imaging and histopathologic examination. Endoscopic excision of the tumour was performed. After three years of follow-up of the patient in our clinic, there was no sign of any recurrence.

Erectile dysfunction in severe sleep apnea patients and response to CPAP.

The aim of this study was to investigate frequency and degree of ED in patients with severe sleep apnea and to evaluate the results of only continuous positive airway pressure (CPAP) therapy on ED in patients with severe obstructive sleep apnea syndrome (OSAS). This was a prospective clinical trial study. Patients with severe sleep apnea (40) were randomized into two groups. Multiple questionnaire investigation and laboratory evaluation were performed for ED, severity of OSAS and psychological status. Group 1 was treated with CPAP and group 2 was treated with only antidepressant medication for at least 1 month. Patients were evaluated after 1 month of therapy and compared with initial ones. Before CPAP, the International Index of Erectile Function (IIEF)-5 scores were significantly correlated only with body mass index (BMI; P=0.007) and not correlated significantly with Epworth Sleepiness Scale scores (P=0.286), lowest SaO(2) (P=0.182), Beck's Depression Inventory scores (P=0.302) and apnea/hypopnea index (P=0.279). After 1 month of regular CPAP usage, mean value of IIEF-5 score was 15.71+/-5.12 before CPAP and were improved up to 19.06+/-3.94, statistically significant. All subjects responded positively to the CPAP treatment and their erection status was improved positively. We have found a correlation between severe OSAS and ED. CPAP is effective in improvement of sexual performance of these patients.

Stoma adjustable silicone gastric banding versus vertical banded gastroplasty for the treatment of morbid obesity.

BACKGROUND: Among gastric restrictive operations, the procedure of choice is still controversial. The aim of this study is to compare the results of two different gastric restrictive procedures: vertical banded gastroplasty (VBG) and stoma adjustable silicone gastric banding (ASGB). METHODS: Between 1991 and 1996, 51 patients were treated surgically for morbid obesity: 27 underwent VBG and 24 underwent ASGB. Preoperative body weight (BW), body mass index (BMI) and percentage of ideal body weight (% IBW) were (mean+/-SD): 145.7+/-45.3 kg; 53.9+/-15.9 kg/m2; 249.1+/-73.5% respectively in the VBG group. Corresponding figures for the ASBG group were 132.5+/-22.7 kg; 46.9 7.8 kg/m2 and 207.2+/-35.0%. RESULTS: In the VBG group, the median follow-up period was 26 months (range: 7-47). Eighteen months after the operation BW, BMI, % IBW and percentage of excess weight loss (% EWL) were 85.5+/-26.8 kg, 31.9+/-9.8 kg/m2, 145.4+/-43.9% and 74+/-1% respectively. Complications included incisional hernia (n=1), and bowel obstruction (n=1). One patient died of acute myocardial infarction on the third postoperative day. In the ASGB group, median follow-up time was 19.7 months (range: 18-26). At 18 months postoperation BW, BMI, % IBW and % EWL values were 86.6+/-20.6 kg 30.6+/-6.6 kg/m2 140.6+/-29.3% and 64+/-1% respectively. Gastric wall erosion occurred in two patients and the bands had to be removed. These patients underwent VBG 6 months later. Complications encountered in this group were incisional hernia (n=1), outlet stenosis and reflux esophagitis (n=1), reservoir leakage (n=1) and gastrointestinal bleeding (n=1). Two patients died of pulmonary embolism and acute gastrointestinal bleeding. CONCLUSIONS: Weight reduction was not statistically significant between the two groups. ASGB was easier to perform and less invasive than VBG.
