OBJECTIVETo explore therapeutic effects of minor external fixator for open comminuted phalangeal fractures with non-transarticular.

METHODSFrom January 2013 to December 2014,13 patients with open comminuted phalangeal fractures were treated by minor external fixator with non-transarticular, including 9 males and 4 females aged from 18 to 56 years old with an average of 35 years old. According to Gustilo classification, 8 cases were type II, and 5 cases were type III. The time from injury to operation ranged from 2 to 7 h averaged 5 h. Seven patients were diagnosed as phalangeal fracture, 6 patients were involved with joint surface of phalangeal, which 1 case combined with inherent nerve damage and 1 case combined with soft tissue defect repaired at stage II. The patients were fixed by plaster for 2 weeks and removal external fixtor from 6 to 8 weeks after operation and received functional exercise.

RESULTSAll patients were followed up from 3 to 12 months with an average of 7 months. One case occurred metacarpophalangeal joints stiffness. No screw breakage, inflammation occurred. Skin soft tissue recovered well and obtained bone healing, the average time of bone healing was (4.6 ± 1.0) weeks. According to TAM scoring system used by Hand Surery Association of Chinese Medical Association, 7 cases got excellent results, 4 good, 1 moderate and 1 poor.

CONCLUSIONMinor external fixator for open comminuted phalangeal fractures with non-transarticular has advantages of simple operation, good stability, and could adjust at the later stage, less damage for soft tissue periosteum, low inflammatory rate, earlier functional exercise. It is worth to be popularized and applied.

Objective To compare the effect of thoracoscopic and laparoscopic surgery with conventional thoracic surgery on esophageal cancer and its influence on pulmonary function. Methods Ninety?four patients with esophageal cancer treated in the Second Affiliated Hospital of Chengdu Medical College from March 2010 to March 2016 were selected and were divided into the control group ( 54 cases) and the study group ( 40 cases) according to operation methods. The control group received traditional thoracotomy. The study group received thoracoscopic and laparoscopic surgery. The operation and pulmonary function indexes were compared. Results The operation time of the patients in the study group was significantly longer than that in the control group ( (218. 1±35. 8) min vs. (192. 3±40. 1) min,t=3. 23,P<0. 05). Intraoperative blood loss of the patients in the study group was significantly less than that in the control group ( (286. 4±83. 5) ml vs. (343. 7 ±96. 7) ml,t=3. 01,P<0. 05) . The number of lymph nodes cleared of the patients was significantly higher in the study group ( (18.0±5.4) node vs. (15.5±4.6) node,t=2.42,P<0.05).Thoracic drainage of the patients in the study group was significantly less than that in the control group ( (650. 3±61. 3) ml vs. (1153. 5 ±133. 7) ml,t=22. 12,P<0. 05). Chest tube pull out time in the study group was significantly earlier than that in the control group ( (5. 1±1. 3) d vs. (8. 0±1. 8) d,t=8. 65,P<0. 05). First exhaust time in the study group was significantly earlier than that in the control group ( (33. 2±6. 7) h vs. (40. 7±7. 3) h,t=5. 10,P<0. 05). Hospital stay in the study group was significantly shorter than that in the control group ( ( 13. 8 ± 2. 8 ) d vs. (18. 2± 3. 6) d, t=6. 42, P<0. 05) . Postoperative complications occurred in 4 cases in the study group, accounting for 10%, significantly lower than that in the control group, 15 cases, 27. 8%, the difference was statistically significant (χ2=4. 50,P<0. 05) . VC,FEV1 and MVV in the study group were significantly higher than those in the control group ( VC:( 81. 5 ± 15. 6 )% vs. ( 42. 3 ± 8. 1 )%;FEV1: ( 85. 7 ± 9. 1 )% vs. ( 43. 6 ±6. 8)%;MVV:(76. 0±8. 9)% vs. (48. 3±7. 6)%,t=15. 83,25. 68,16. 24,P<0. 05). 3?year survival rate of the study group and the control group were 45. 0% (18/40) and 44. 4% (24/54),respectively. There was no significant difference between the two groups (χ2 = 0. 01, P> 0. 05 ) . Conclusion Thoracoscopic and laparoscopic surgery for esophageal cancer has the advantages of small trauma,rapid recovery and low incidence of complications and obvious protective effect on pulmonary function. It is safe and feasible.
