ObjectiveTo investigate the clinical application of laparoscopic right hemihepatectomy via anterior approach. MethodThe clinical data of 32 patients underwent laparoscopic right hemihepatectomy via anterior approach from June 2017 to May 2019 were retrospectively analyzed.ResultsThe laparoscopic right hemihepatectomies via anterior approach were successfully completed in the 32 patients, no one converted to laparotomy. The operation time was (315.5±36.7) min, the intraoperative bleeding was (340.8±105.4) mL, and the postoperative hospital stay was (8.9±1.7) d. The postoperative complications occurred in 6 cases, including 1 case of peritoneal effusion, 1 case of intraabdominal infection, 2 cases of bile leakage and 2 cases of pleural effusion combined with pulmonary infection, who were discharged after receiving the conservative treatment according to the symptoms. The results of postoperative pathology: 13 cases of hepatocellular carcinoma, 6 cases of intrahepatic cholangiocarcinoma, 7 cases of hepatic angioleiomyoma, 6 cases of intrahepatic bile duct stones. The average follow-up time was 12 months (range 1 to 24 months). During the follow-up period, 7 cases of hepatic angioleiomyoma and 6 cases of hepatolithiasis survived after operation. The intrahepatic metastases were found in 1 patient with hepatocellular carcinoma at 12 months and 2 cases of intrahepatic cholangiocarcinoma at 9 months and 11 months, respectively. The rest patients survived free tumor.ConclusionLaparoscopic right hemihepatectomy via anterior approach is safe and feasible, and has a satisfactory short-term efficacy.
ObjectiveTo retrospectively compare the mid-term effectiveness between by direct anterior approach (DAA) and by posterolateral approach in total hip arthroplasty (THA).MethodsBetween January 2009 and December 2010, 110 patients (110 hips) treated with THA and followed up more than 5 years were chosen in the study. THA was performed on 55 patients by DAA (DAA group), and on 55 patients by posterolateral approach (PL group). There was no significant difference in gender, age, body mass index, types of hip joint disease, and preoperative Harris score between 2 groups (P>0.05). The operation time, amount of bleeding, length of hospital stay, postoperative complications, and the Harris scores were recorded and compared.ResultsThere was no significant difference in operation time and length of hospital stay between 2 groups (t=0.145, P=0.876; t=1.305, P=0.093). The amount of bleeding was significantly less in DAA group than in PL group (t=2.314, P=0.032). All patients were followed up 5-7 years (mean, 5.97 years). Complications happened in 5 cases (9.1%) of DAA group and in 3 cases (5.5%) of PL group, and there was no significant difference in the incidence of complications between 2 groups (χ2=0.539, P=0.463). There was significant difference in Harris scores at 6 months after operation between 2 groups (t=2.296, P=0.014), but no significant difference was found in Harris score at 1 year and 5 years between 2 groups (t=1.375, P=0.130; t=0.905, P=0.087). Further analysis, at 6 months after operation, the joint function score in DAA group was significantly higher than that in PL group (t=1.087, P=0.034), while there was no significant difference in the pain score and range of motion score between 2 groups (t=1.872, P=0.760; t=1.059, P=0.091).ConclusionTHA by DAA has the advantages of less bleeding and faster recovery. The short-term effectiveness is superior to the THA by traditional posterolateral approach, but there is no obvious advantage in the mid-term effectiveness.
ObjectiveTo investigate the accuracy of preoperative digital-template planning in total hip arthroplasty (THA) via direct anterior approach (DAA) and its effect on the short-term effectiveness.MethodsThe clinical data of 77 patients (109 hips) with osteonecrosis of femoral head who underwent THA via DAA between January 2016 and May 2018 was retrospectively analyzed. According to the type of template, patients were divided into digital-template group (group A, 40 patients, 56 hips) and conventional-template group (group B, 37 patients, 53 hips). There was no significant difference in age, gender, body mass index, the stages of osteonecrosis of femoral head, and preoperative Harris hip score (HHS) (P>0.05). The operation time, intraoperative blood loss, frequencies of intraoperative fluoroscopy, and complications were recorded. Otherwise, the consistency rate of preoperative planning and practical prosthesis size was analyzed. Position of acetabular prosthesis and femoral prosthesis alignment were measured on anteroposterior X-ray film of the pelvis at 3 months after operation. HHS was used to evaluate clinical function.ResultsThe consistency rate of preoperative planning and practical acetabular prosthesis size was significantly higher in group A (80.4%, 45/56) than that in group B (62.3%, 33/53), showing significant difference (χ2=4.38, P=0.04). But there was no significant difference in the consistency rate of preoperative planning and practical femoral prosthesis size between group A (83.9%, 47/56) and group B (79.2%, 42/53）(χ2=0.40, P=0.53). The prosthesis abductions were (40.7±6.4)° in group A and (38.8±7.3)° in group B; the femoral prosthesis alignment deviations were (0.1±1.8)° in group A and (0.3±1.7)° in group B. There was no significant difference in the prosthesis abduction and femoral prosthesis alignment deviation between 2 groups (P>0.05). No prosthesis sinking or loosening occurred during follow-up. The operation time and frequencies of intraoperative fluoroscopy were less in group A than those in group B (P<0.05). But there was no significant difference in intraoperative blood loss between 2 groups (t=1.92, P=0.06). The complication occurred in 1 hip of group A and 6 hips of group B, with no significant difference (P=0.06). All patients were followed up 6-22 months (mean 13.8 months) in group A and 6-24 months (mean, 14.6 months) in group B. At last follow-up, the HHS scores were 91.8±3.1 in group A and 92.6±4.2 in group B, and the difference was not significant (t=1.14, P=0.26).ConclusionPreoperative digital-template planning in THA via DAA is accurate, which can reduce the operation time and frequencies of intraoperative fluoroscopy without enhancing the risk of complication.
ObjectiveTo explore the feasibility and effectiveness of total hip arthroplasty (THA) with acetabulum structural bone grafting using autogenous femoral head through direct anterior approach (DAA) in lateral decubitus position in the treatment of Crowe type Ⅲ and Ⅳ developmental dysplasia of the hip (DDH). Methods Between June 2016 and July 2020, 12 patients with Crowe type Ⅲ and Ⅳ DDH were treated with THA with acetabulum structural bone grafting using autogenous femoral head through DAA in lateral decubitus position. There were 2 males and 10 females with an average age of 60.2 years (range, 50-79 years). Crowe classification was type Ⅲ in 10 hips and type Ⅳ in 2 hips. The preoperative Harris score of hip joint was 48.8±7.5, the difference in length of both lower extremities was (3.0±0.7) cm, and the visual analogue scale (VAS) score during activity was 7.2±0.9. The surgical incision length, operation time, intraoperative blood loss, and complications were recorded; the position and press-fitting of acetabulum and femoral prosthesis were observed after operation, and the difference in length of both lower extremities was measured; the horizontal coverage of acetabular cup and bone graft were measured, the healing with the host bone and the loosening of the prosthesis were evaluated; Harris score was used to evaluate hip joint function, and VAS score was used to evaluate patients’ pain during activity. Results The average surgical incision length was 9.3 cm, the average operation time was 117 minutes, and the average intraoperative blood loss was 283 mL. Two patients (16.7%) received blood transfusion during operation. There was no acetabular and femoral fractures during operation. All incisions healed by first intention, without dislocation, periprosthetic infection, sciatic nerve injury, deep venous thrombosis, and other complications. One patient had lateral femoral cutaneous nerve injury after operation. X-ray films at discharge showed a total acetabular cup level coverage of 93%-100%, with an average of 97.8%, and a bone graft level coverage of 25%-45%, with an average of 31.1%. All the 12 patients were followed up 22-71 months, with an average of 42.2 months. At last follow-up, the Harris score of hip joint was 89.7±3.9, the difference in length of both lower extremities was (0.9±0.4) cm, and the VAS score during activity was 1.1±0.6, which were significantly different from those before operation (P<0.05). During follow-up, there was no patient who needed hip revision surgery because of prosthesis loosening. At last follow-up, there was no translucent line between the graft and the host bone, the graft was fused, the position was good, and there was no obvious movement. One patient had one screw fracture and bone resorption at the outer edge of the graft, but the bone graft did not displace and healed well. ConclusionTHA with acetabulum structural bone grafting using autogenous femoral head through DAA in lateral decubitus position in the treatment of Crowe type Ⅲ and Ⅳ DDH is safe and reliable, and has satisfactory short-term effectiveness.
ObjectiveTo systematically review the efficacy of total hip arthroplasty by direct anterior approach (DAA) and direct lateral approach (DLA). MethodsCNKI, WanFang Data, VIP, CBM, EMbase, PubMed, The Cochrane Library, ClinicalTrials.gov and PROSPERO databases or websites were electronically searched to collect randomized controlled trials (RCTs) of DAA and DLA for THA from inception to August 6th, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 9 RCTs were included. The results of meta-analysis showed that at 3 months post-operation, the Harris hip score (HHS) of the DAA group was higher than the DLA group (MD=4.83, 95%CI 2.09 to 7.56, P=0.000 5). Besides, compared with the DLA group, the DAA group showed shorter incision length (MD=−2.35, 95%CI −3.90 to −0.79, P=0.003), less intraoperative bleeding (MD=−68.24, 95%CI −119.07 to −17.41, P=0.009), and shorter hospital stay (MD=−0.84, 95%CI −1.54 to −0.15, P=0.02). However, no significant differences were found between DLA and DAA in operation duration and HHS at 6 weeks after operation. ConclusionsCurrent evidence shows that DAA can provide better HHS at 3 months post-operation, shorter incision length, less intraoperative bleeding, and shorter hospitalization length than DLA. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
ObjectiveTo evaluate the feasibility and clinical value of robot-assisted lobectomy through anterior approach.MethodsWe retrospectively analyzed the clinical data of 180 patients who underwent robot-assisted lobectomy through anterior approach in our hospital between April 2017 and February 2018. There were 97 males and 83 females, aged 59.5 (32.0-83.0) years. The clinical effects were analyzed.ResultsOne patient was transferred to thoracotomy due to tumor invasion of adjacent blood vessels and injury to the blood vessels, and there was no perioperative death. There were 8.5 (1.0-35.0) dissected lymph nodes for each patient. The median operation time was 120 (50-360) min, including robot Docking time 5 (1-23) min and robot operation time 65 (7-270) min. The median blood loss was 50 (5-1 500) mL, 132 (73.3%) patients had malignant tumors and median drainage time was 5 (2-30) d. The mean postoperative pain score was 3.4±0.7 points and the postoperative hospital time was 8 (2-32) d. At the median follow-up of 24 months, 11 patients developed recurrence and metastasis, and 3 died.ConclusionRobot-assisted lobectomy through anterior approach is a safe and convenient operation method, which is worthy of clinical application.
Objective To compare the differences in acetabular position during total hip arthroplasty (THA) between by direct anterior approach and by posterolateral approach. Methods Between December 2008 and December 2015, 102 patients undergoing THA were included in the study. THA was performed by anterior approach in 51 cases (anterior group) and by posterolateral approach in 51 cases (posterolateral group). There was no significant difference in gender, age, body mass index, side, and cause of illness between 2 groups (P>0.05), with comparability. The acetabular abduction angle and anteversion angel were measured on the X-ray film at 1 day after operation to evaluate whether the acetabular prosthesis was displaced in the safe zone. Results The acetabular abduction angle was (42.28±5.77)° in the anterior group and was (43.93±7.44)° in the posterolateral group, showing no significant difference (t=1.30, P=0.19). The acetabular anteversion angle was (21.14±5.17)° in the anterior group and was (21.05±4.10)° in the posterolateral group, showing no significant difference (t=0.05, P=0.96). The ratio in the target safe zone of the acetabular abduction angle in the anterior group and the posterolateral group were 88.2% (45/51) and 84.3% (43/51) respectively, showing no significant difference (χ2=0.33, P=0.56). The ratio in the target safe zone of the acetabular anteversion was 80.4% (41/51) in the anterior group and was 82.4% (42/51) in the posterolateral group, showing no significant difference between 2 groups (χ2=0.06, P=0.79). The ratio in the target safe zone of both the abduction and anteversion angel was 70.6% (36/51) in the anterior group and was 68.6% (35/51) in the posterolateral group, showing no significant difference (χ2=0.05, P=0.82). Conclusion There is no differences in the acetabulum position during THA between by direct anterior approach and posterolateral approach.
ObjectiveTo explore the effectiveness of minimally invasive clamp reduction technique via anterior approach in treatment of irreducible intertrochanteric femoral fractures.MethodsBetween January 2015 and January 2019, 59 patients with irreducible intertrochanteric femoral fractures were treated with minimally invasive clamp reduction technique via anterior approach. There were 29 males and 30 females with an average age of 77.9 years (range, 45-100 years). The causes of injury included falling in 46 cases, traffic accident in 6 cases, smashing in 2 cases, and falling from height in 5 cases. The time from injury to operation was 1-14 days (mean, 3.8 days). The fractures were classified as AO type 31-A1 in 12 cases, type 31-A2 in 25 cases, type 31-A3 in 22 cases.ResultsAll fractures were reduced well and the fracture reduction took 10 to 30 minutes, with an average of 19 minutes. All patients were followed up 13-25 months, with an average of 17.6 months. Among them, 2 cases of pronation displacement of proximal fracture segment died for infection or falling pneumonia after internal fixation failed. Six patients with reversed intertrochanteric femoral fractures experienced re-pronation and abduction displacement of the lateral wall after internal fixation, but the fractures all healed. The rest of the patients had no fracture reduction loss, and the fractures healed with an average healing time of 5.9 months (range, 3-9 months). Except for 2 patients who died, the Harris score of hip joint function of the remaining 57 patients was excellent in 49 cases and good in 8 cases at last follow-up.ConclusionThe minimally invasive clamp reduction technique via anterior approach for irreducible intertrochanteric femoral fractures is simple and effective. For irreducible intertrochanteric femoral fractures related to lateral wall displacement, after clamp reduction and intramedullary nail fixation, the lateral wall should be reinforced in order to avoid reduction loss and internal fixation failure.
Objective To compare the short-term effectiveness of staged bilateral total hip arthroplasty via different approaches. Methods Thirty-two patients (64 hips) with bilateral hip disease were treated with total hip arthroplasty between January 2012 and December 2014. There were 20 males and 12 females with the mean age of 45.3 years (range, 30-67 years). There were avascular necrosis of femoral head in 14 cases, developmental dislocation of the hip in 12 cases, ankylosing spondylitis in 4 cases, osteoarthritis in 2 cases. All patients were treated with total hip arthroplasty; and the direct anterior approach (DAA) or direct lateral approach (DLA) was chosen for the unilateral hip randomly. The length of incision, operation time, total blood loss volume, the time of first postoperative activity, and the acetabular anteversion angle were compared. The Harris score, visual analogue scale (VAS) score, and incidence of complication were compared between 2 groups. Results All incisions healed at stage Ⅰ. All patients were followed up 20-53 months (mean, 39.6 months). The length of incision, total blood loss volume, the time of first postoperative activity were significantly shorter in DAA group than in DLA group (P<0.05). The operation time was significantly longer in DAA group than in DLA group (P<0.05). There was no significant difference in acetabular anteversion angle between 2 groups (t=1.122, P=0.266). The incidence of complication were 25.00% and 15.63% in DAA group and DLA group, respectively, showing no significant difference (χ2=0.869, P=0.536). The Harris score in DAA group significantly increased at 3 and 9 months after operation than in DLA group (P<0.05); there was no significant difference at 18 months after operation between 2 groups (P>0.05). The VAS score was significantly lower in DAA group than in DLA group at 1 day, 3 days, and 1 week after operation (P<0.05); there was no significant difference at 4 and 8 weeks between 2 groups (P>0.05). The prosthesis did not loosen and sink during the follow-up. Conclusion Total hip arthroplasty via DAA can reduce operation related complication and speed up the recovery of hip function at the early stage after operation. However, the lateral cutaneous nerve injury is the most common complication.
Objective To evaluate the short-term effectiveness of minimally invasive total hip arthroplasty (THA) by direct anterior approach (DAA). Methods Between January and August 2014, THA was performed on 48 patients (60 hips) by DAA (group A), and on 72 patients (92 hips) by posterolateral approach (group B). There was no significant difference in gender, age, etiology, course, and preoperative visual analogue scale (VAS), Harris hip score (HHS), and hip range of motion (ROM) between 2 groups (P>0.05). The operation time, intraoperative blood loss, postoperative drainage, hospitalization time, incision healing, and complications were recorded and compared. The acetabular abduction and anteversion were measured on the X-ray films; prosthesis loosening was observed. The VAS score, HHS score, and hip ROM were used to evaluate the hip function. Results The operation time and intraoperative blood loss of group A were significantly higher than those of group B, and the hospitalization time was significantly lower than group B (P<0.05), but no significant difference was found in postoperative drainage between 2 groups (t=0.71,P=0.46). The patients were followed up 2-2.5 years (mean, 2.2 years) in group A, and 2-2.5 years (mean, 2.1 years) in group B. In group A, 3 cases had lateral femoral cutaneous nerve traction injury and 1 case had swelling and exudate, and primary healing of incision was obtained in the other cases of group A and all cases of group B. No periprosthetic joint infection occurred in the others of groups A and B except 1 case of group A at 2 months after operation, and infection was controlled after debridement, irrigation, and intravenous infusion of Vancomycin for 1 month. The X-ray films showed good position of prosthesis and no obvious radiolucent line or prosthesis loosening. There was no significant differences in acetabular abduction and anteversion between groups A and B at last follow-up (P>0.05). The VAS score, HHS score, and hip ROM at 3 months and last follow-up were significantly better than preoperative ones in 2 groups (P<0.05), but no significant difference was found between at 3 months and last follow-up (P>0.05). The VAS score, HHS score, and hip ROM in group A were significantly better than those in group B at 3 months postoperatively (P<0.05). At last follow-up, the hip ROM in group A was significantly better than that in group B (P<0.05), and there was no significant difference in VAS and HHS scores between group A and group B (P>0.05). Conclusion The short-term effectiveness of minimally invasive THA by DAA is satisfactory, with the advantage of little trauma, short hospital stay, and rapid postoperative recovery.
