Objective To evaluate the clinical outcomes of external fixator with lumbopelvic distraction spondylodesis in treatment of vertically unstable pelvic fractures. Methods From January 2008 to March 2009, 9 patients (4 males and 5 females) with a vertically unstable pelvic fracture were treated with modular external fixator with lumbopelvic distraction spondylodesis. According to the classification of Tile, 9fractures were classified as type C. This fixation construct comprises a vertical lumbopelvic distraction component which fixed L4.5 and the posterior superior iliac spine and a transverse fixation which fixed anterior iliac spine with external fixator. Results All patients were followed up 12-18 months after surgery, with an average of 14.3 months. Postoperative X-ray showed satisfactory reduction of pelvic fracture. Pelvic fractures healed in all patients without loss of reduction 3-6 months after operation. According to Matta reduction evaluation criteria, 6 patients were excellent and 3 good. For the two patients with sacral neurological injuries,appropriate surgical decompression was performed to improve the symptom and minimize the deformity. No iatrogenic complications of neurovascular injury occurred. Patients now walk unassistedly without pain in the waist or legs, and with no shortening of lower limbs or claudication. By considering symptom and satisfactory scores, the Majeed functional assessment revealed that seven patients had excellent results and two good at one year. Conclusion External fixator with lumbopelvic distraction spondylodesis that allowed early mobilization and ambulation, with general applicability and definite safety, is an effective surgical technique for the treatment of vertically unstable pelvic fracture.

Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

Objective To analyze the relationship between cervical lordosis and the development of dysphagia after anterior cervical spine surgery.Methods From June 2007 to May 2010,data of 172 successive patients who had undergone ACDF operation in our hospital were reviewed in this study.The presence and duration of postoperative dysphagia were recorded via face-to-face questioning or telephone interview at least one year after the procedure.Plain cervical radiographs before and after surgery were collected.The C2-7 angle was measured.The change of C2-7 angle was defined as dC2-7 angle=postoperative C2-7-preoperative C2-7 angle.The correlation between postoperative dysphagia and dC2-7 angle was studied.Results There were 22 patients in dysphagia group,including 17 males and 5 females.Their age ranged from 25 to 70 years old,and average was 47.7±5.4.The average of BMI was 25.0±2.9 kg/m2.150 patients were in non-dysphagia group,including 101 males and 49 females.Their age ranged from 18 to 72 years old,and average age was 49.2±4.8.The average of BMI was 24.4±3.4 kg/m2.There was no statistical difference in gender,age,and BMI between two groups.The dC2-7 angle of dysphagia group ranged from-1 °-20.5°,and average was 8.6°±4.0°.The dC2-7 angle of non-dysphagia group ranged from-13°-28.5°,and average was 5.0°±4.3°.There was significant difference in dC2 7 angle between dysphagia and non-dysphagia group.Spearman Analysis revealed that there was strong correlativity between dC2-7 angle and postoperative dysphagia.When dC2-7 angle was greater than 5°,the chance of developing postoperative dysphagia significantly increased (19.3％ [17/88] vs 6.0％ [5/84]).What's more,Spearman Analysis also revealed that there was no correlativity between dC2 7 angle and degree of operative dysphagia.There was no significant difference in gender,age,and BMI between dysphagia and non-dysphagia group.There was no statistical difference in operative time,blood loss revision surgery,revision surgery ratio,most cephalic operative level and number of operative levels between dysphagia with non-dysphagia group.Logistic regression model showed that an increased likelihood of postoperative dysphagia persists with increasing dC2-7 angle,but had no relationship with operative time,blood loss,revision surgery,most cephalic operative level and number of operative levels.Conclusion dC2-7 angle may play an important role in the development of postoperative dysphagia.We found no statistical difference in operative time,blood loss revision surgery,revision surgery ratio,most cephalic operative level and number of operative levels between dysphagia and non-dysphagia group.Intraoperative measurement of the dC2-7 angle is practical and essential for reducing the postoperative dysphagia.

Objective To explore the impact of combined laparoscopic and choledochoscopic treatment on bile leak in hepatic hydatid disease at a high attitude region.Methods The clinical data of 50 patients who underwent combined laparoscopic and choledochoscopic treatment were compared with 50 patients who underwent laparoscopic surgery alone for hepatic hydatid internal capsule excision surgery.Results In the combined laparoscopic and choledochoscopic group,the incidence of biliary fistula after surgery was 15％,the incision infection rate was 13％,the length of hospitalization was (11.6 ± 3.8) days and the postoperative time to take off drain was (14.3 ± 7.9) days.These were significantly better than those in the laparoscopic alone group.The operation time in the former group was (108.2 ± 28.4)min,which was slightly longer than the laparoscopy group.Conclusion The combined laparoscopic and choledochoscopic treatment is a safer therapeutic option in treating hepatic hydatid disease with less trauma,faster recovery and shorter hospital stay than laparoscopic surgery alone in a high attitude region.

Objective To compare the perioperative outcomes and short-term efficacy of three-port extraperitoneal laparoscopic radical prostatectomy (ELRP) and four-port ELRP.Methods Two hundred patients who had undergone ELRP for prostate cancer by a single surgeon from November 2010 to October 2014 were retrospectively analyzed.Among them,95 cases underwent three-port ELRP and 105 cases underwent four-port ELRP.On the basis of traditional four-port ELRP,three-port ELRP was characterized by the omission of the trocar on the inner side of right anterior superior iliac spine.The mean age was 66.8 ± 15.5 years,and mean total prostate specific antigen (tPSA) was 15.3 ± 12.4 μg/L.There were no significant differences including age,body mass index,tPSA,clinical stages,acceptance of neoadjuvant hormone therapy,history of transurethral resection of the prostate,history of diabetes mellitus between the 2 groups (P ＞ 0.05).Patients in three-port ELRP group had significantly smaller prostate volume than fourport group (35.6 ± 16.7 ml versus 42.2 ± 24.7 ml,P ＜ 0.05).The clinical factors as operative time,estimated blood loss,hospital stay,drainage tube keeping days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates were compared between the 2 groups.Results The three-port group had significantly shorter operative time than the four-port group (81.0 ± 18.6 min versus 103.6 ±34.6 min),less estimated blood loss (102.6 ±75.8 ml versus 217.5 ± 182.9 ml),less positive surgical margin rates (13.7％ versus 27.6％).There were 9 patients having Gleason scores more than 7 in the three-port ELRP group and 29 patients in four-port ELRP group (P ＜ 0.05).There were no significant differences of hospital stay,drainage tube keeping days,pathological stages between the 2 groups (P ＞ 0.05).Eighty-three cases in the three-port ELRP group (87.4％) were followed up for 5-19 months with the median time of 11 months.Ninety-two cases in fourport ELRP group (87.6％) were followed up for 17-52 months and the median time was 27 months.There were no significant differences of biochemical recurrence rates and urinary incontinence rates between the 2 groups(P ＞ 0.05).Conclusions Compared to four-port ELRP,three-port ELRP can provide shorter operative time,less blood loss,better negative surgical margin rates,similar oncological control and recovery of postoperative continence.In experienced hands,three-port ELRP could be a feasible and effective option for localized prostate cancer.
