Clinical manifestations vary depending on the location of BZ from no symptoms to acute abdominal syndrome. When located in small bowel, they frequently cause small bowel obstruction (SBO). We aimed to present our experience by reviewing literature.METHODS: Thirty-four patients with gastrointestinal BZ were presented. The data were collected from hospital records and analyzed retrospectively. Morbidity and mortality rates were statistically analyzed between the subgroups according to SBO and endoscopic or surgical treatment modalities.RESULTS: The 34 patients had phytobezoars (PBZ). Two patients with mental retardation and trichotillomania had trichobezoars (TBZ). More than half of them (55.88%) had previous gastric surgery. Also most of them had small bowel bezoars resulting in obstruction. Surgical and endoscopic morbidity rates were 32.14% and 14.28% respectively.The total morbidity rate of this study was 29.41%. Four patients in surgically treated group died. There was no death in endoscopically treated group. The total and surgical mortality rates were 11.76% and 14.28% respectively. The differences in morbidity and mortality rates between the subgroups were not statistically significant.CONCLUSION: BZ are commonly seen in stomach and small intestine. SBO is the most common complication.When uncomplicated, endoscopic or surgical removal can be applied easily.展开更多

Because of legal-ethical concerns, there have not been many publications on this topic. Delays in diagnosis and treatment might increase mortality and morbidity. Radiological imaging is used in diagnosis. We present a case of gossypiboma that had fistulized to bulbous following hydatic cyst surgery. We established the diagnosis with endoscopy and followed its migration endoscopically.展开更多

This could partly be attributed to the tighter legislation imposed by the government in these countries on detergents and other corrosive products and general public awareness. Most busy upper gastrointestinal surgical units in these countries, especially in the developed countries will only encounter a small number of cases per year. Up to date knowledge on the best management approach is lacking. In this article, we present our experience of two contrasting cases of corrosive injury to the upper gastrointestinal tract in our thoracic unit in the last 2 years and an up-to-date Medline literature search has been carried out to highlight the areas of controversies in the management of corrosive injuries of the upper gastrointestinal tract. We concluded that the main principle in managing such patients requires a good understanding of the pathophysiology of corrosive injury in order to plan both acute and future management. Each patient must be evaluated individually as the clinical picture varies widely. Signs and symptoms alone are an unreliable guide to injury.展开更多

Methods:We compared and analyzed various kinds of imaging examinations such as barium esophagram, con-trast-enhanced computed tomography (CT) and conventional gastroscopy in retrospectively reviewing the clinical data of an esophageal hamartoma patient seen in our clinic in the First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, China. Having received various imaging examinations, this patient was finally diagnosed with esophageal hamartoma and underwent gastroscopic resection of hamartoma with the diagnostic information obtained from EUS. The patient had been regularly followed up for 13 months after treatment. Results: Barium esophagram, CT and conventional gastroscopy detected the lesion, but were unable to distinguish it from common esophagopolypus and other submucosal lesions, and unable to determine etiopathogenisis. EUS detected the hamartoma and identified its internal structure, echo, exact size, depth of invasion, origin and the relationship between adjacent tissues and organs, differentiating the lesion from other submucosal tumors and clearly defining the diagnosis. EUS-guided fine needle aspiration (FNA) also helped to identify the etiological diagnosis. Conclusion: EUS was superior to other imaging means in diagnosis and treatment of hamartoma.展开更多

METHODS： Thirty-one patients with hypopharyngeal squamous cell carcinoma had been operated, with radical intent, at our Institution in the period between 1978 and 2004. Due to obstructive tumor mass, in 7 （22.6%） patients, preoperative endoscopic evaluation of the esophagus and stomach could not be performed. In those patients, intraoperative endoscopy, made through an incision in the cervical esophagus, was standard diagnostic method for examination of the esophagus and stomach. RESULTS： We found synchronous foregut carcinomas in 3 patients （9.7%）. In two patients, synchronous carcinomas had been detected during preoperative endoscopic evaluation, and in one （with obstructive carcinoma） using intraoperative endoscopy. In this case, preoperative barium swallow and CT scan did not reveal the existence of second primary tumor within esophagus, despite the fact that small, but T2 carcinoma, was present. CONCLUSION： It is reasonable to use intraoperative endoscopy as a selective screening test in patients with obstructive hypopharyngeal carcinoma.展开更多

Methods： From January 2000 to October 2006, 52 patients with far-lateral lumbar disc herniation （29 males and 23 females, with the average age of 41.5 years） were treated with minimally invasive procedures. All the patients were assessed by X-ray and CT. Some were given additional myeography, discography, Computerized tomography myelography （CTM） and MRI examination. Yeung Endoscopy Spine System （YESS）, METRx and X-tube procedures were performed in 25, 13 and 14 cases, respectively. All patients were followed up for a mean period of 13.5 months. Clinical outcomes were assessed by visual analog score （VAS） and Nakai criteria. Results： The results indicated that the three procedures could significantly improve the radiating leg symptoms （P〈0.05）. The postoperative overall excellent and goodrates of YESS, METRx and X-tube procedures were 84.0%, 84.6% and 92.8% respectively, with no statistical difference among three groups （P〉0.05）. The YESS procedure had several advantages including shortest operation time, simplest anesthesia and least trauma as compared with the other two procedures, especially for simple type I far-lateral lum- bar disc herniation. METRx procedure was specially suitable for simple type II. And the procedure of posterior endoscopic facetectomy, posterior lumbar interbody fusion and unilateral pedicle screw instrumentation with X-tube was designed for far-lateral disc herniation combined with degenerative lumbar instability. Conclusion： Minimally invasive strategies and options should be determined by different types of far-lateral lumbar disc herniation.展开更多
