Objective To evaluate the diagnostic value of MRI in hepatic echinococcosis.Methods MRI features of 37 cases with hepatic echinococcosis proved by operation and pathology were analysed in comparison with that of CT.Results The hepatic echinococcosis could be divided into five types according to the manifestations of CT and MRI:simple cyst in 8 cases,multiple daughter cyst in 13 cases,ruptured cyst in 7 cases,consolidated and calcified cyst in 4 cases and mixed cyst in 5 cases.Conclusion MRI can clearly show and determine the location,size,form,number and types of hepatic echinococcosis,that are helpful for the plan of operation.

Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.

OBJECTIVETo explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology.

METHODSThe patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation.

RESULTSThe distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved.

CONCLUSIONSRapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

Objective To study the effects of nerocutneous vessels on perforator flap blood supply and survival area. Methods Thirty SD rats were randomly divided into 3 groups. The study of the vasculature and nerve disposition of rat dorsum was performed with 10 rats of one group. According to the study,a distal rectangle neurocutaneous flap based on deep circumflex iliac artery perforator, 10 cm long and 3 cm in the width, was elevated on the rest rats, and sutured back to the original situation. The axis of the experimental group's flap paralleles the posterior median line,while the control group flap's angulated about 30° with it. The blood flow of the flap was assessed by fluorescein angiography on the 1st and 7th day after surgery. The surviving rate and the capillary density of flap were assessed on the 7th day after surgery. Results The rat deep circumflex iliac perforator artery was a constant perforator artery, with an nutrition area about 4 cm× 3 cm. The dorsal cutaneous nerves run along the dorsomedian line, nourished by rich vessels. The blood perfusion 1st day after surgery was 42.85% in the experimental group, 37.94% in the control group(P ＞ 0.01 ).On the 7th day, it was 84.07% in the experimental group, 58.55% in the control group (P＜ 0.01). The mean survival rate of the experimental group was 83.93%, higher than control group's 59.95% (P＜0.01),and the density of the blood vessels was higher in experimental group than control group's. Conclusion The neurocutaneous vessels can improve the flap survival condition, which make the perforator flap bigger and safer.

Objective To explore the feasibility and short-term efficacy of laparoscopic and thoracoscopic Ivor Lewis esophagectomy using a circular-stapled anastomosis with trans-oral anvil in treating esophageal carcinoma.Methods 30 consecutive patients with esophageal cancer received minimally invasive Ivor Lewis esophagectomy from January 2011 to December 2011.Operations of all the cases comprised of both abdominal and thoracic procedures which were performed with Iaparoscopic and thoracoscopic techniques respectively.The intrathoracic esophago-gastric anastomosis was created using a circular-stapled anastomosis with trans-oral anvil technique.Results There were 24 males and 6 female with median age of 62.5-year-old (from 47 to 82).The lesions located in middle and/or lower portion of the esophagus.25 patients with esophageal squamous cell cancer (n =25) and 5 patients with adenocarcinoma (n =5) underwent an Ivor Lewis esophagectomy.All the operations were successfully performed without intra-operative technical failures of the anastomosis or deaths.The mean operation time was 95 minutes in abdomen and 177 minutes in thorax.The mean blood loss was 310 ml.The mean number of harvested lymph nodes was 10.6 from thorax and 4.9 from abdomen.Postoperalively,there were thoracic wound infections in 4 patients.One patient had a left diaphragmatic hernia and was successfully treated by re-operation 6 days after first operation.One patient had chylothorax and recovered without surgery.There was no anastomotic leak and the patients were able to have spoon meat at 5.6 postoperative days.Conclusion Laparoscopic and thoracoscopic Ivor Lewis esophagectomy can be accomplished smoothly with acceptable occurrence of complications.The circular-stapled anastomosis with the trans-oral anvil is an efficient,safe and reproducible technique for intrathoracic esophago-gastric anastomosis.
