  • PREVENTION AND MANAGEMENTS OF PELVIC CAVITY MASSIVE HEMORRHAGE IN OPERATIONS OF RECTAL CARCINOMA

    目的介绍直肠癌根治手术中防止盆腔大出血的经验与紧急处理措施。方法1993年8月至2000年4月我科完成直肠癌根治手术687例。术者掌握盆腔解剖,沿间隙操作,保护好骶前静脉丛; 沿髂内动脉内侧镰状筋膜处理侧韧带,有时结扎直肠中动脉; 肿瘤浸润阴道或前列腺可边切除边缝合; 盆腔侧壁中度浸润者可在侧方淋巴结清除的同时,合并髂内动、静脉分支和肿瘤切除。发生盆腔大出血,根据大出血部位及肿瘤情况可采用骶丛止血钉按压法,纱布压迫止血法,缝扎止血法或血管修补术止血。结果发生术中大出血仅14例,术中失血量<400 ml 5例,400~800 ml 8例,>800 ml 1例。止血后未发生再次大出血。行Miles手术8例,保肛手术6例,无手术中死亡。结论直肠癌根治手术中按解剖层次正确操作,阻断直肠周围血流可防止盆腔大出血。发生盆腔大出血可用骶丛止血钉、纱布压迫、缝扎止血或血管修补术止血。

  • PREVENTION AND TREATMENT OF LEG LENGTH DISCREPANCY AFTER TOTAL HIP ARTHROPLASTY

    【Abstract】 Objective To explore the prevention and treatment of leg length discrepancy after total hip arthroplasty(THA). Methods There were 87 patients who were treated by THA from January 2004 to December 2006, including 36males and 51 females, with the average age of 60.2 years (ranging from 35 years to 78 years). Among these cases, there were 35 of avascular necrosis of the femoral head, 38 of subcapital femoral neck fracture, 4 of femoral neck tumor, 6 of rheumatoid arthritis and 4 of acetabular dysplasia. In 70 cases, the patients had leg length discrepancy, and the legs shortened from 1 cm to 6 cm. Based on the cl inical measurement and radiographic examination, the surgical protocols were designed, the type of the hip prosthesis was chosen, and the neck length of the femoral prosthesis and the position of osteotomy were estimated. By the proper wearing of the acetabula, the best rotation point was found out. The cut plane of the femoral neck was adjusted according to the results of the radiographic and other examinations. The neck length was readjusted after the insertion of the prosthesis so as to achieve intended leg-length equal ization. The discrepancy of the leg length was measured and evaluated after operation. Results Superficial infestation happened in 2 cases 5 days after the operation and was cured by mero-drainage. Luxation happened in 4 cases 4 weeks after the operation, in which 2 cases were cured by operation while the other 2 were cured by manual reduction. All the patients were followed up for 6 months to 36 months, with the average time of 18.3 months. The Harris scores were 34.81 ± 1.36 preoperatively and 91.50 ± 1.87 postoperatively (P lt; 0.05). In the 17 patients with equal legs before the operation, 1 was lengthened 1.5 cm in the leg, while in the 70 patients with shortened legs before the operation, 66 returned to the same length in their legs, and 4 were lengthened or shortened from 1.6 cm to 2.1 cm. The total rate of equal leg length was 94.25%. Conclusion The preoperative measurement, radiographic templating and intraoperative correction, together with postoperative orthopraxy, are effective in prevention and treatment of leg length discrepancy after THA.
