More and more relevant research results show that anatomical segmentectomy has the same effect as traditional lobectomy in the surgical treatment of early-stage non-small cell lung cancer (diameter<2.0 cm). Segmentectomy is more difficult than lobotomy. Nowadays, with the promotion of personalization medicine and precision medicine, three-dimensional technique has been widely applied in the medical field. It has advantages such as preoperative simulation, intraoperative positioning, intraoperative navigation, clinical teaching and so on. It plays a key role in the discovery of local anatomical variation of pulmonary segment. This paper reviewed the clinical application of three-dimensional technique and briefly described the clinical application value of this technique in segmentectomy.
Objective To evaluate the cl inical results of the femoral reconstruction technique in patients with proximal femoral deformity in total hip arthroplasty. Methods Between March 2004 and June 2009, total hip arthroplasty procedures were performed on 25 patients (26 hips) with hip joint disease and proximal femoral deformity, including primary osteoarthritis of the hip joint (2 hips), developmental dysplasia of the hip (8 hips), traumatic arthritis of the hip (14 hips), and tuberculosus arthritis of the hip (2 hips). There were 10 males (10 hips) and 15 females (16 hips), with an average age of 64 years (range, 42-82 years). The disease duration was 10 months to 25 years (mean, 10.6 years). The Harris score was 44.2 ± 5.1, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score was 45.0 ± 2.7 before operation. According to Berry’s classification system of primary disease, 8 hips were classified as developmental dysplasia of hip, 7 hips as malunion of fracture, 2 hips as chronic tuberculosis, 2 hips as sl ipped femoral epiphysis, 1 hip as previous subtrochanteric osteotomy, 1 hip as previous shelf operation of the acetabulum, and 5 hips as previous internal fixation; according to the anatomic site of the deformity, there were 5 hips of greater trochanter, 10 hips of femoral neck level, 10 hips of metaphyseal level, and 1 hip of diaphysis. Results All wounds healed by first intention. Deep venous thrombosis occurred in 3 patients within 1 week, and were cured with braking and anticoagulant therapy. Bursal synovitis of great trochanter occurred in 1 patient after 6 weeks, and was eased after taking drugs for pain rel ief. All patients were followed up 1 year and 6 months to 6 years, with an average of 3 years and 3 months. The Harris score and WOMAC score at last follow-up were 88.4 ± 3.6 and 82.0 ± 5.2 respectively, showing significant differences when compared with preoperative scores (P lt; 0.05). The X-ray films at last follow-up showed good location of prosthesis and no loosening expect 1 patient who had aseptic loosening and was given revision at 8 months postopera tively. Conclusion Proximal femoral deformity classification will contribute to the choice of prosthesis and surgical strategy,thus the good results of femoral reconstruction and cl inical results would be obtained.

ObjectiveTo investigate the diagnosis and treatment value of multi-disciplinary team (MDT) model in patient with gastrointestinal stromal tumor (GIST) with liver metastasis.MethodThe experiences of MDT model in treating huge (>10 cm) GIST with liver metastasis in the Affiliated Hospital of North Sichuan Medical College on August 2018 were summarized.ResultsThe 46 years old female patient diagnosed with intestinal stromal tumor with liver metastasis at the initial visit. There was no chance of surgery. After the neoadjuvant therapy, the tumor was shrunk. After 2 MDT discussions, the R0 resection of the primary tumor or metastases was successfully performed. And then the patient continued to receive the oral imatinib 600 mg/d. The current overall survival was 31 months till now. No recurrence of the tumor was observed and the follow-up was still continued.ConclusionsTyrosine kinase inhibitors combined metastasectomy may be the most appropriate treatment for patient diagnosed with GIST with liver metastasis, which can improve the survival. In clinical work, MDT model could be used reasonably and carried out during the whole treatment process to provide the best treatment option for patient with GIST with liver metastasis.
ObjectiveTo investigate the effectiveness of flap combined with induced membrane technique in treatment of post-traumatic tibial osteomyelitis with soft tissue defect. Methods A clinical data of 33 patients with post-traumatic tibial osteomyelitis with soft tissue defect who met the selection criteria between August 2015 and October 2018 was retrospectively analyzed. There were 21 males and 12 females. The age ranged from 19 to 70 years, with an average of 39 years. The osteomyelitis located in the upper 1/3 of tibia in 8 cases, in the middle 1/3 of tibia in 14 cases, and in the lower 1/3 of tibia in 11 cases. According to Cierny-Mader classification standard, 19 cases of osteomyelitis were type Ⅲ and 14 cases were type Ⅳ. The duration of osteomyelitis ranged from 2 months to 20 years (median, 3 months). In the first-stage operation, after radical debridement, the length of bone defect was 1.5-12.5 cm (mean, 5.0 cm) and the size of soft tissue defects ranged from 5 cm×4 cm to 15 cm×12 cm. Bone cement containing antibiotics was implanted into the bone defect and the personalized flap was used to repair the wound. After the wound healed at 6-8 weeks and the infection was controlled, bone grafting was performed to repair bone defects in the second-stage operation. Results The flaps survived completely after the first-stage operation in 29 cases. Partial necrosis of the flap occurred in 4 cases and healed after surgical dressing change. All the incisions healed by first intention after the second-stage operation. All patients were followed up 24-32 months (mean, 28 months). All the bone grafts healed after operation, and the radiographic healing time was 3-9 months (mean, 5 months). The clinical healing time was 4-14 months (mean, 8 months). There was no recurrence of osteomyelitis during follow-up. At last follow-up, according to Johner-Wruhs evaluation criteria, the limb function was excellent in 27 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 93.9%. Conclusion For the post-traumatic tibial osteomyelitis with soft tissue defect, the flap combined with induced membrane technique is a reliable and effective method and can effectively restore the function of lower limbs with satisfactory effectiveness.
Objective To evaluate the effectiveness of membrane induction technique in the treatment of Gustilo-Anderson ⅢB type injury of distal femur complicated with bone defect. Methods The clinical data of 20 patients with Gustilo-Anderson ⅢB type injury of distal femur complicated with bone defects admitted between January 2019 and December 2020 were retrospectively analyzed, including 15 males and 5 females, with an average age of 35 years (range, 19-70 years). Causes of injuries included 15 cases of traffic accidents and 5 cases of falling from height. Bone defect located at metaphyseal in 11 cases and at proximal metaphyseal in 9 cases. The time from injury to primary first-stage surgery was 4-28 hours, with an average of 11 hours. After primary radical debridement, the length of bone defect was 3-12 cm, with an average of 6 cm. Antibiotic-containing bone cement was implanted in the bone defect site to induce membrane formation. At 34-56 days (mean, 45 days) after the first-stage surgery, bone grafting was performed in the induced membrane for the repair and reconstruction of bone defects; 16 patients received a combination of autogenous cancellous and allogeneic bone grafts and 4 patients received cancellous bone grafts. The bone graft healing time after the second-stage surgery was recorded; the visual analogue scale (VAS) score and Lysholm score were compared before the second-stage bone graft and at last follow-up to evaluate the pain and functional improvement of the affected limb; and the knee joint range of motion at last follow-up was recorded. Results None of the patients had a second revision after the first-stage surgery, 1 patient recieved flap transfer and the flap survived well after operation. All patients were followed up 12-36 months after the second-stage surgery, with an average of 23 months. All patients achieved bone union, and the bone union time was 7-10 months (mean, 8.4 months). No bone nonunion or donor site related complications occurred. The Lysholm score and VAS score at last follow-up were 85.6±4.1 and 1.7±0.8, respectively, and they were significantly improved when compared with those before the second-stage bone defect repair (42.7±4.6 and 7.1±0.8, respectively) (t=37.410, P<0.001; t=21.962, P<0.001). Knee flexion range of motion was 60°-120°, with an average of 95°; the limit of elongation was 0°-10°, with an average of 5°. ConclusionFor Gustilo-Anderson ⅢB type injury of distal femur complicated with bone defect, induction membrane technique can effectively control infection, promote bone healing of the defect site, and effectively restore the function of lower limbs with satisfactory effectiveness.
Objective During primary total knee arthroplasty (TKA), anticoagulant drugs are used for prevention of major venous thrombosis of lower limbs, and this often leads to the increase of perioperative blood loss. To retrospectively analyse the impact of low molecular weight heparin on hidden blood loss and transfusion rate after primary TKA by comparing with the use of aspirin. Methods Between October 2007 and August 2009, the clinical data from 286 patients undergoing primary TKA surgery were retrospectively analyzed. In accordance with different anticoagulation methods, the cases were divided into 2 groups, the trial group (n=166) and the control group (n=120). In the trial group, the patients received low molecular weight heparin (4 000-6 000 U/day) from 8-12 hours after TKA for 14 days; there were 27 males and 139 females with an average age of 66.1 years (range, 22-82 years); the body mass index (BMI) was 26.79 ± 3.87; and the locations were the left knee in 99 cases and the right knee in 67 cases with an average disease duration of 4.1 years (range, 1.8-8.6 years). In the control group, the patients received aspirin (150 mg/day) for 14 days; there were 21 males and 99 females with an average age of 64.9 years (range, 40-84 years); the BMI was 27.87 ± 3.62; and the locations were the left knee in 78 cases and the right knee in 42 cases with an average disease duration of 4.9 years (range, 1.5-8.2 years). There was no significant difference in the general data between 2 groups (P gt; 0.05). Results The incisions healed by first intention in all patients. Postoperative deep venous thrombosis occurred in 37 patients of the trial group and in 28 cases of the control group. All the patients were followed up 12-34 months (mean, 21.6 months). There were significant differences in the United States Hospital for Special Surgery (HSS) score of 2 groups between before surgery and after surgery (P lt; 0.05). The hidden blood loss was (40.55 ± 37.75) g/L in the trial group and (32.52 ± 40.13) g/L in the control group, showing significant difference (t=3.387, P=0.001); the dominant blood loss was (24.08 ± 14.63) g/L and (27.91 ± 18.47) g/L respectively, showing no significant difference (t= —1.899, P=0.059). The blood transfusion rates were 40.4% (67/166) in the trial group and 30.0% (36/120) in the control group, showing no significant difference (χ2=2.771, P=0.081); the transfusion volumes were (1.44 ± 4.03) U and (0.97 ± 3.50) U respectively, showing significant difference (t=2.071, P=0.039). Conclusion The low molecular weight heparin has effect on the hidden blood loss after primary TKA, which may increase postoperative blood loss and blood transfusion rate. The changes in hemoglobin should be monitored during the anticoagulant therapy, and the blood volume should be added promptly.
