ABSTRACT
The 2-μm thulium laser resection of the prostate-tangerine technique (TmLRP-TT) has been introduced as a minimally invasive treatment for benign prostatic hyperplasia (BPH). This study was undertaken to assess the clinical efficacy and safety of TmLRP-TT for the treatment of BPH patients with previously negative transrectal prostate biopsy. A prospective analysis of 51 patients with previously negative transrectal prostate biopsy who underwent surgical treatment using TmLRP-TT was performed from December 2011 to December 2013. Preoperative status, surgical details, and perioperative complications were recorded. The follow-up outcome was evaluated with subjective and objective tests at 1 and 6 months. TmLRP-TT was successfully completed in all patients. Mean prostate volume, operative duration, and catheterization time were 93.3 ± 37.9 ml, 69.5 ± 39.5 min, and 6.5 ± 1.3 days, respectively. The mean International Prostate Symptom Score, quality of life score, maximum urinary flow rate, and post-void residual urine volume changed notably at 6-month follow-up (22.5 ± 6.9 vs 6.1 ± 3.2, 4.8 ± 1.3 vs 1.1 ± 0.9, 7.3 ± 4.5 vs 18.9 ± 7.1 ml s-1 , and 148.7 ± 168.7 vs 28.4 ± 17.9 ml). Two (3.9%) patients required blood transfusion perioperatively, while 3 (5.9%) patients experienced transient hematuria postoperatively, and 2 (3.9%) patients received 3 days recatheterization due to clot retention. TmLRP-TT is a safe and effective minimally invasive technique for patients with previously negative transrectal prostate biopsy during the 6-month follow-up. This promising technology may be a feasible surgical method for previously negative transrectal prostate biopsy in the future.
ABSTRACT
La utilización del LASER de CO2 en laringología comenzó en la década del 80, permitiendo la exéresis de tumores por vía transoral. Su indicación se basa en los excelentes resultados oncológicos. La función deglutoria postquirúrgica es un factor importante en la calidad de vida de los pacientes con cáncer del tracto aerodigestivo superior. Los resultados de la deglución son relevantes para elegir la modalidad terapéutica, la cual debe ser no sólo efectiva en controlar el cáncer sino también en preservar la función del órgano. El grado y el tipo de alteración deglutoria deben ser determinados en forma precisa, para establecer el tratamiento postoperatorio adecuado. Esto es posible mediante estudios como la videodeglución y la evaluación endoscópica de la deglución (FEESST)...
The CO2 laser have been used for treatment of laryngeal cancers since 1980, with excellent oncological results. The swallowing plays an important roll in superior aerodigestive cáncer patient. Swallowing results are relevant to choose the therapeutic modality, which must be effective in controlling not only cancer but also in preserving organ function. The degree and type of swallowing impairment must be determined precisely, to establish the appropriate postoperative treatment. This is possible through studies like videodeglucion and endoscopic evaluation of swallowing (FEESST)...

Purpose To compare the therapeutic effects of CO2 laser resection and traditional split laryngeal surgery on the early laryn-geal cancer, and to examine relationship between the expression of p27 and PTEN and clinical prognosis in early laryngeal squamous cell carcinoma. Methods 85 patients who underwent CO2 laser resection surgery and 46 patients who underwent split laryngeal surger-y were selected and the occurrence rates after surgery were observed. SP immunohistochemical method was uesd to detect the expression of p27 and PTEN in tumor resection marginal and their surgical margine tissues. Clinical data were collected and all patients were fol-lowed up. Results In the more than two-year follow-up study, 14 of 85 patients in CO2 laser treatment group ( recurrent group) pres-ented with local recurrence and the recurrence rate was 16. 5%, while 6 of 46 patients in split laryngeal surgery group presented with local recurrence and the recurrent rate was 13. 0%. There was no statistical significance in recurrence rate between the two groups ( P> 0. 05). 10 of all the none recurrent patients did not follow the doctor’s advice to quit smoking after the operation, while 12 in the recurrent patients did not, the difference between the two groups was statistically significant (P<0. 01). The positive rate of p27 and PTEN in laryngeal carcinoma tissues and the cancer adjacent tissues ( negative surgical margin tissues ) was 43. 5% ( 57/131 ) , 80. 2% (105/131) and 48. 9% (64/131), 83. 2% (109/131), respectively, with a significant difference (P<0. 01). The positive rate of p27 and PTEN in laryngeal carcinoma tissues of the recurrent group and non recurrent group was 20. 0% (4/20), 47. 7% (53/111) and 10. 0% (2/20), 55. 9% (62/111), respectively, with a significant difference (P<0. 05). While the positive rate of p27 and PTEN in tumor resection marginal tissues of the recurrence group and non recurrence group was 50. 0% ( 10/20 ) , 85. 6% ( 95/111) and 40. 0% (8/20), 91. 0% (101/111), the difference was also statistically significant (P<0. 01). Conclusions There was no statistically significant difference in tumor recurrence rate between CO2 laser surgery and traditional split laryngeal surgery. Postoper-ative recurrence is closely related to resume smoking. The recurrence rate of p27 and/or PTEN negative patients was higher than that of the opposite ones which should be followed up closely after treatment.
ABSTRACT
BACKGROUND AND OBJECTIVES: Voice quality may be an important issue for choosing treatment options of early glottic cancer. It has been reported that voice quality is worse after laser cordectomy compared to that of radiation therapy. But, with developed visualization tools, the precise localization of lesions became possible enabling surgeons to decide the appropriate surgical extent to preserve voice after laser cordectomy. The authors assessed the postoperative voice quality of patients who underwent laser cordectomy according to the classification by the European Laryngological Society. SUBJECTS AND METHOD: Thirty patients who were diagnosed with glottic cancer and treated with laser cordectomy between April, 1999 and January, 2006, were evaluated. All the patients were followed-up more than 6 months. Objective evaluations included maximal phonation time, fundamental frequency, jitter, shimmer, noise-to-harmonics ratio and subjective evaluation was performed by the GRBAS scale. RESULTS: The type II laser cordectomy group and some cases of the type III cordectomy showed no significant differences compared with the normal control group in both objective and subjective evaluations. CONCLUSION: This study shows that the group of laser cordectomy type II and some cases of type III had acceptable results compared to that of the normal control group. Thus, laser cordectomy could be considered as an alternative to radiation therapy in selected patients with early glottic cancer, even when preserving the quality of voice is an important issue.

BACKGROUND AND OBJECTIVES: Pain control is one of the most important factors for the patients that underwent the snoring surgery. This study was performed to investigate the effectiveness of intravenous patient-controlled analgesia (PCA) for postoperative pain control after tonsillectomy with laser resection of palatopharynx. MATERIALS AND METHODS: In this double-blind randomized study, 44 patient were randomly allocated to 2 groups. In the PCA group comprising 32 patients, fentanyl citrate, ketorolac tromethamine and zofran in normal saline solution were administered by PCA equipment. In the control group comprising 12 patients, normal saline solution was given without analgesic drug by PCA equipment. Visual analogue pain score (VAS) was recorded right after surgery and 2, 4, 6, 12, 18, and 24 hours after surgery and satisfaction score was recorded just before discharge from the hospital. RESULTS: VAS was significantly higher in the control group of all time points. Overall satisfaction score was also higher in PCA group than control group. CONCLUSION: The results of this study suggest that intravenous PCA is an effective method for postoperative pain control after tonsillectomy with laser resection of palatopharynx.

A 42 years old male was transferred to the hospital for the treatment of endobronchial mass. He had a history of cough with initial hemoptysis. The endoscopic finding showed endobronchial mass totally occluded left upper lobe bronchus. The initial biopsy revealed chronic inflammation. The patient was scheduled for bronchoscopic laser photoresection and the mass was removed with the stump left at superior segment of lingular lobe. Endobronchial hamartoma was diagnosis from pathological section. The case is reported and the review of endobronchial hamartoma is presented.
