Laser treatment of esophageal cancer by endoscopy in 15 cases

Ming-Fa Deng Jibing. A poor white students responsible for this good / ('7 ~ / c of a ------~ one - a Vi We l993 period on March 6 Endoscopic laser treatment of advanced esophageal cancer l5 cases of curative effect satisfaction. clinical data of a, in general, the age of this group of 50 .7 to 71-year-old Liao, the average age 6O, l years old. l3 cases of squamous cell carcinoma. adenocarcinoma in 2 cases. lesions; upper section 2 cases, 4 cases of middle and lower segment 0 down . lesions {3 ~ lOcm. l5 cases were confirmed by X-ray examination. swallow choking feeling stems ll cases, the food .. into the normal diet 5 sides, into the semi-liquid diet (semi-liquid food) in 8 cases, into the liquid diet (liquid food I guillotine),[link widoczny dla zalogowanych], can not eat l cases. cachexia 2 side. onset to diagnosis for 1 to 4 months. an average of 1.5 months. Third, the treatment of routine preparation before endoscopy, the endoscopy biopsy holes into the Nd: YAG laser fiber, the first ammonia-neon laser with red light for directions aligned lesions, with power 6.84 ~ 7.6kV, the wavelength 1.O6m laser, launch angle of 70 ~ 80., foot switch control of emission. each treatment more emission of lesions, usually 10 ~ l2, and every point of 5 ~ 3Os. sub-fiber contact with lesions treated with the non-contact lesions. Each weeks of treatment 1. general treatment an average of 3 to 5 times 0 times four, efficacy standards (1) markedly effective: symptoms, normal diet can be hired, x-ray of the original lesions disappeared or almost disappeared, no cancer cells in pathological examination. (2) effective; symptom relief, improved eating, x-ray of the original lesion reduced 1 / 2, and pathology no cancer cells. (3) is invalid: no change in symptoms, eating no improvement. V. Results after treatment , the markedly 1I (73.3), 2 cases (13.3%), 2 cases (13.3%). Treatment of 1 in 3 cases to alleviate the symptoms, treatment, symptom relief 3 times in 8 cases, the treatment 6 2 sides to alleviate the symptoms. ineffective in 2 cases, J Department of esophageal lumen cases the basic block, only liquid food, lesion length 10cm, after 6 treatments, no improvement in symptoms of esophageal cancer recurrence, Department of J cases, kiss Taiwan mouth closed, not into the flow of food, treatment 5 times,[link widoczny dla zalogowanych], no improvement in symptoms. In addition to 2 patients in this group retrosternal burning sensation, but no case of serious complications. 6 patients 2 weeks after laser treatment, radiation therapy linear accelerator 20 to 35 times. 6 months after treatment, follow-up, survivors 1O cases, the survival rate 66.7K1 carp fr11fd20). 6 patients with radiation therapy to discuss the current caught survival, treatment is surgical treatment of esophageal cancer, non-surgical treatment of radiotherapy and chemotherapy , laser, microwave therapy,[link widoczny dla zalogowanych], have a certain effect. this group of patients with laser treatment to improve the quality of life has a good effect, and its advantages are: (1) the treatment is simple, time is short, you can repeat the treatment,[link widoczny dla zalogowanych], the effective rate was recently 86.6. (2) laser treatment through gasification, carbonization and biological effect, can effectively kill cancer cells, expansion of the narrow esophageal lumen, to improve the food situation, enhance physical fitness, and create conditions for further treatment. (3) can not be tolerated surgery, radiotherapy and chemotherapy offers an effective therapeutic approach. (4) surgical complications, fewer complications, safe and reliable. treatment, non-contact laser-focus breathing exercises for patients, esophageal peristalsis and increased the difficulty of the operation, but not easily bleeding, a good operative field, the operation time is short. exposure to a laser focus, operation and accurate, but easy to stick to the carbon fiber after the organization to reduce the laser power; stretch easily after bleeding, affect the surgical field of vision, and the need to repeatedly clear the treatment of carbon fiber organization. Both methods have advantages and disadvantages. the laser can effectively kill the tumor cells to the cavity growth, while growth of the esophageal cancer cells and surrounding tumor is invalid. Therefore, the end station radiotherapy and chemotherapy can improve survival rate. In the choice of cases should be strictly controlled indications, the group 2 cases were ineffective due to esophageal lumen blockage thereof,[link widoczny dla zalogowanych], lesions longer than blind treatment, after the 1st treatment of necrotic tissue remains in the esophagus lumen loss, difficult removal, poor vision, affecting surgical operation, f} jI spent a long time. welcome to subscribe to f995 of journals, for the destruction of health, medicine defense research, medical education and medical institutions character of health books, medical intelligence Subscribe to the 3002 / R.
