Objective To investigate the technique and clinic value of non-operation management for ERCP-related peripancreatic and retroperitoneal abscess. Methods Five patients with post-ERCP peripancreatic and retroperitoneal abscess were reviewed. Guided by ultrasonic or CT, all the 5 pa-tients underwent puncture and the drainage tube was disposed to the lowest place of abscess. Non-op-eration managements for patients also included the use of anti-inflammatory drugs and enzyme activity inhibition drugs. Results All patients responded to the draining treatment and discharged from hospi-tal after complete recovery. There was no conversion to surgical intervention. Mean draining duration was 52. 4(20-90)d and average hospital stay was 91.8(35-165)d. Conclusion Puncture and drainage management is an effective and safe approach for post-ERCP peripancreatic and retroperitoneal ab-scess. It has advantages of less trauma, less pain, fast recovery and low rate of complications. Punc-ture point should be situated at the bottom or lowest position of abscess and drainage can achieve the best results.

BACKGROUND:Decel ularized scaffolds are special for retaining the tubular structure used for nutrition transport, and providing a similar inner environment for cel growth. OBJECTIVE:To study the preparation of the decel ularized whole liver bioscaffold and to explore its repair outcomes for liver injury. METHODS:Livers from 12 Sprague-Dawley rats were used for preparing the decel ularized whole liver bioscaffold by chemical detergent-enzymes decel ularized technology. Models of liver injury were established in another 24 Sprague-Dawley rats and randomized into two groups:the decel ularized whole liver bioscaffold was implanted into the rat liver lesions in experimental group, and controls were given the injection of normal saline. Thirty days later, the serum levels of alanine aminotransferase and glutamic-oxaloacetic transaminase were detected, and liver tissues were removed for hematoxylin-eosin staining. RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that extracel ular matrix-like structures existed in the decel ularized bioscaffold;cel components were completely removed from the liver, the col agen fibers in the scaffold arranged regularly and were not dissolved under electron microscope. The serum levels of alanine aminotransferase and glutamic-oxaloacetic transaminase in the experimental group were significantly lower than those in the control group (P<0.05). Hematoxylin-eosin staining showed a large number of blue-stained and dense distributed nuclei, and pink distribution of col agen fibers that had no overt breakages in the control group, while pink and dense structures in the experimental group. These results suggest that the decel ularized whole liver bioscaffold is easy to obtain, and can promote the injured liver repair.

Objective:This paper aims to demonstrate the maxillary mucosa restoration after operation to the nasal fungal sinusitis. Methods Observation by microscopic, transmission electron microscopic and scanning electron microscopic was done to the same parts in the maxillary mucosa 3-4 months before and after the endoscopic sinus surgery in the 24 cases of the nasal fungal sinusitis during 2003-2005. Result: Before the operation, all the cases demonstrated epithelia shedding, proliferation, squamous metaplasia, glandular and fibrous tissue proliferation and lymphocytes infiltration. The microtubule was abnormal and mitochondria diminished,3-4 months after operation, the cavity was clear and smooth and the epithelia complete. The cilia average increased and the cilia lined in the same direction. The structure of microtubules was clear. The mitochondria was elongated and dense. Conclusion: There was no significant difference in the damage on ultramicrostructure of the maxillary mucosa between the chronic nasal sinusitis and chronic nasal fungal sinusitis. It is crucial in the successful recovery that the operation gives a thorough clean to the fungal clot and sinus aeration, and that good cleaning and sinus aeration are maintained after the operation. The ultramicrostructure restoration and the function recovery of mucosa will be achieved after careful cleaning for 3-4 months after operation.

Coblation is a new technology widely used in the otolaryngology in recent years.This article described the principle,indications,methods and advantages which the coblation was used in pharynx and throat diseases in children.It's a safe,effective and minimally invasive way.

Objective To compare the efficacy of chronic hypertrophic rhinitis by partial inferior turbinectomy and using semiconductor laser surgery .Methods The efficacy of 53 chronic hypertrophic rhinitis patients with partial inferior turbinectomy(groupⅠ) and 62 patients treated with semiconductor laser surgery(groupⅡ) were analyzed retrospectively.Results the total effective rate of the groupⅠ treated by semiconductor laser surgury was 87 1% and groupⅡ treated by partial inferior turbinectomy was 90 4%. There was no significant difference (P

OBJECTIVE: To investigate the therapeutic effects of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome. METHOD: A review of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome was presented with respect to the sleep monitoring results, SF-36 health questionnaire survey, therapeutic effects and complications. RESULT: After operation for 6 months, the patients' sleep Monitoring results were improved remarkably (P<0. 01) and their symptoms of snore or choke got improved. SF-36 health questionnaire survey showed that social function, energy and mental health dimension scores were significantly higher than the preoperative (P<0. 05). There were 18 patients suffered Secondarily bleeding within 2 weeks and 23 patients recrudesced within 1 year. CONCLUSION Radio frequency coblation is an applicable method of therapy for patients with obstructive sleep apnea-hypopnea. The treatments differ with the obstructive location and character of upper airway.

OBJECTIVE: The aim of this study is to explore the applications of digital department in otolaryngology concern with the emergent and dangerous of otolaryngology diseases. METHOD: We have constructed digital otolaryngology head and neck surgery department on the basis of hospital information system, which is constructed under the guidance of the theories and methods of modern information integration technology, computer software technology, health informatics and network information technology. RESULT: The foundation of digital otolaryngology department can optimize digital workflow, improve work efficiency and eliminate the manual operation. CONCLUSION Digital department in otolaryngology will promote the quality and upgrade the level of medical staff, it plays an important role in the hospital informationization.

OBJECTIVE: To investigate the efficacy of Coblation-channelling for the tongue(CCT) treatment of tongue hypertrophy. METHOD: The 31 patients with severe obstructive sleep apnea hypopnea syndrome (OSAHS) combining tongue hypertrophy staged as Friedman ll or N were performed CCT after nasal septum surgery, coblation channelling of bilateral inferior turbinate and coblation-assisted UPPP. While the vertical channelling in the base and the body of the tongue, the tilted one parallel side edge and posterior to the tongue were combined. The intraoperative and postoperative complications such as bleeding were observed. The 12 months postoperative follow-up were done by MRI of the tongue. RESULT: The retrolingual space were expanded postoperatively. The 2 bleedings occurred immediately after channellings in the tongue body, and they were stopped by local compression. No postoperative tongue paralysis, no tongue hematoma and abscess happened. The tongue sizes changed from preoperative III or IV degree to postoperative I to II degrees. One case received three CCT sessions. CONCLUSION CCT treatment tongue hypertrophy is a individually safe, effective and minimally invasive treatment.
