AIM To define clinical criteria to differentiate eosinophilic gastrointestinal disorder(Eo GD) in the esophagus. METHODS Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis(Eo E), subepithelial eosinophilic esophagitis(s Eo E) and eosinophilic esophageal myositis(Eo EM), identified by endoscopy, manometry and serum immunoglobulin E levels(s-Ig E), in combination with histological and polymerase chain reaction analyses on esophageal tissue samples.RESULTS In five patients with Eo E, endoscopy revealed longitudinal furrows and white plaques in all, and fixed rings in two. In one patient with s Eo E and four with Eo EM, endoscopy showed luminal compression only. Using manometry, failed peristalsis was observed in patients with Eo E and s Eo E with some variation, while Eo EM was associated with hypercontractile or hypertensive peristalsis, with elevated s-Ig E. Histology revealed the following eosinophils per high-power field values. Eo E = 41.4 ± 7.9 in the epithelium and 2.3 ± 1.5 in the subepithelium; s Eo E = 3 in the epithelium and 35 in the subepithelium(conventional biopsy); Eo EM = none in the epithelium, 10.7 ± 11.7 in the subepithelium(conventional biopsy or endoscopic mucosal resection) and 46.8 ± 16.5 in the muscularis propria(peroral esophageal muscle biopsy). Presence of dilated epithelial intercellular space and downward papillae elongation were specific to Eo E. Eotaxin-3, IL-5 and IL-13 were overexpressed in Eo E.CONCLUSION Based on clinical and histological data, we identified criteria, which differentiated between Eo E, s Eo E and Eo EM, and reflected a different pathogenesis between these esophageal Eo GDs. 展开更多

Objective: of chronic subdural hematoma The surgical management (CSDH) is still a controversial issue, and a standard therapy has not been established because of the unclear pathogenic mechanisms in CSDH. The intention of this paper is to find a simple and efficient surgical procedure for CSDH. Methods: A retrospective study of 448 patients with CSDH by surgical treatment during 2005 to 2009 was conducted in order to compare the efficiency between two diferent primary surgical methods, i.e. twist-drill drainage without irrigation in Group A (n-178) and one burr-hole with irrigation in Group B (n=270). The results were statistically analyzed. Results: The reoperation rates in Group A and Group B were 7.9% and 11.9% respectively. The good outcome rate was 88.8% and 73.5%, the complicatiGn was 7.9% and 20.7% in Group A and Group B, respectively. Conclusions: The burr-hole drainage with irrigation of the hematoma cavity is not beneficial to the outcome and prognosis. Irrigation is not important in the surgical treatmerit for CSDH. Thus in initial treatment, twist-drill drainage without irrigation of the hematoma cavity is recommended because it is relatively safe, time-saving and cost-effective. 展开更多

Purpose: Posterior fossa epidural hematomas (PFEDH) are uncommon in children but usually require timely surgical intervention due to the risk of life-threatening brainstem compression. We attempt to make the surgical procedure less invasive by treating selected pediatric patients with trephination minicraniectomy. Methods: We retrospectively reviewed the clinical courses, radiological findings, surgical procedures, and prognoses of the pediatric patients who were treated in our departments for traumatic PFEDH from January 2010 to January 2015. Results: During this period, a total of 17 patients were surgically treated for PFEDH and 7 were managed with trephination mini-craniectomy for hematoma evacuation. The outcomes were good in all 7 patients as evaluated with Glasgow Outcome Score. There was no mortality in this series. The on average 30-month clinical follow-up showed that patients experienced satisfactory recoveries without complications. Conclusion: Our results suggest that trephination mini-craniectomy is a safe surgical technique for selected PFEDH patients with moderate hematoma volume and stabilized neurological functions. However, standard craniectomy is recommend when there are rapid deteriorations in patients' neurological functions or the hematomas are large and exerted severe mass effects. 展开更多

Breakage of surgical instruments and implants during operative procedures is not uncommon in any surgical discipline. The need for removal and the out come of leaving the broken instruments and implants in the surgical area have not been described in detail. Few studies have suggested removal if they are lying loosely in the tis sues or joint, close to neurovascular structures. Challenges and the amount of time spent in the retrieval of broken instruments and implants are well most choose to leave them in known among surgeons, so situ. We reported a novel method of retrieval of a broken drill bit in the femoral medul lary canal during internal fixation of a type C distal femoral fracture. 展开更多
