Objective To evaluate application of anterior approach combined with selective hepatic vein(s) occlusion in associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) for giant hepatocellular carcinoma (HCC) in right lobe. Method The clinical data of 9 patients underwent the ALPPS in the First Affiliated Hospital of Guangxi Medical University from January 2017 to September 2017 were retrospectively analyzed. Results Six cases underwent the complete ALPPS, 3 cases lost because it couldn’t match the standard for the second step. After the first step, The average increased volume of the future liver remnant (FLR) was 139.1 cm3 (46.4–291.6 cm3), and the average increased volume rate of FLR was 37.8% (15.1%–76.2%). The average blood loss was 356 mL (200–600 mL). In the second step, 4 cases underwent the right hemihepatectomy and 2 cases underwent the extend right hemihepatectomy, the average blood loss was 617 mL (300–1 400 mL). There was no bile fistula, liver failure, and death. Conclusions Preliminary results of limited cases in this study show that application of anterior approach combined with selective hepatic vein(s) occlusion is a safe and feasible strategy in ALPPS for giant HCC in right lobe. This strategy is conformity with the " no touch” principle of oncology surgery, and reduces blood loss and decreases complications. Long-term oncological result of ALPPS in HCC patients with cirrhosis is unknown.
Objective To compare the effectiveness of one-stage bilateral total hip arthroplasty by direct anterior approach (DAA) and by posterolateral approach, and to investigate the application value of DAA in one-stage bilateral total hip arthroplasty. Methods The clinical data of 65 patients who underwent one-stage bilateral total hip arthroplasty by DAA or posterolateral approach between June 2010 and November 2015 were analyzed retrospectively. DAA was used in 34 cases (group A) and posterolateral approach was used in 31 cases (group B). There was no significant difference in the gender, age, body mass index, preoperative hemoglobin level, etiology, disease duration, preoperative Harris score, and preoperative visual analogue scale (VAS) score between 2 groups (P>0.05) with comparability. The incision length, operation time, intraoperative blood loss, total blood transfusion volume, hospitalization time, early postoperative complications, Harris score, and VAS score were recorded and compared between 2 groups. The simple Likert scale method was applied to evaluate the patient satisfaction, and the imaging evaluation was used. Results The incision length, operation time, intraoperative blood loss, total blood transfusion volume, and hospitalization time of group A were significantly less than those of group B (P<0.05). The patients were followed up 15-48 months (mean, 25.3 months) in group A and 12-51 months (mean, 27.6 months) in group B. The overall incidence of complications related to surgery in group A (10.29%) was significantly lower than that of group B (19.35%) (χ2=8.769, P=0.023). The acetabular anteversion and abduction angle were in the normal range of 2 groups except 1 hip (1.47%) of group A had a higher acetabular anteversion than normal value. Unstable fixed prosthesis happened in 1 hip of groups A and B respectively, and the remaining femoral calcar had no obvious bone resorption and fixed stably. The Harris score and VAS score at each time point after operation of 2 groups were significantly improved when compared with preoperative scores (P<0.05), and the differences between the time points after operation were also significant (P<0.05). The Harris score at 1 and 3 months after operation and the VAS score at 3 days after operation of group A were significantly better than those of group B (P<0.05), but no significant difference was found at last follow-up between 2 groups (P>0.05). According to the simple Likert scale method to analyze patient satisfaction, comprehensive satisfaction of group A (97.1%, 33/34) was significantly higher than that of group B (67.7%, 21/31) (χ2=10.343, P=0.001). Conclusion The application of DAA in one-stage bilateral total hip arthroplasty can significantly relieve the pain, accelerate the recovery of hip joint function, and improve the patient satisfaction. But in clinical application, more attentions should be paid to strictly grasp the indications and prevent the early complications. The long-term effectiveness needs to be further observed.
ObjectiveTo evaluate the short-term effectiveness of arthroscopic surgery combined with direct anterior approach for hip diseases.MethodsA retrospective study was performed on 23 cases with hip diseases (23 hips), who were treated with the arthroscopic surgery combined with direct anterior approach, between January 2015 and December 2016. There were 9 males and 14 females, aged from 27 to 49 years (mean, 38.6 years). There were 11 cases of posterior dislocation of the hip associated with femoral head fracture (Pipkin typeⅠ) and 7 cases of femoral neck fracture (Garden type Ⅳ). And the interval between injury and operation was 2-8 days (mean, 4.3 days). Five cases were osteonecrosis of femoral head at precollapse stage which were rated as stageⅡA according to Association Research Circulation Osseous (ARCO) classification system. The disease duration was 3-8 months (mean, 5.9 months). The preoperative Harris hip score, Oxford Hip Score (OHS), Postel score, and visual analogue scale (VAS) were 57.3±8.2, 11.2±3.6, 3.2±1.5, and 7.2±1.3, respectively.ResultsAll the wounds healed primarily. Lateral femoral nerve injury occurred in 3 cases. All patients were followed up 8-19 months (mean, 15.6 months). Bone union achieved in all patients after 14-19 weeks (mean, 15.8 weeks) and no secondary osteoarthritis or heterotopic ossification occurred. At last follow-up, the Harris hip score (92.5±5.3), OHS (36.5±5.9), and Postel score (14.2±2.6) were significantly higher than preoperative scores (t=45.274, P=0.000; t=36.586, P=0.000; t=32.486, P=0.000), and VAS score (1.8±0.9) was significantly lower than preoperative score (t=21.314, P=0.000).ConclusionArthroscopic surgery combined with direct anterior approach for hip diseases can effectively relieve pain, improve hip function, and obtain the 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.
Objective To investigate the effectiveness of MAKO robotic-arm assisted total hip arthroplasty (THA) via direct anterior approach (DAA) for bony fused hips in ankylosing spondylitis (AS). Methods Between June 2021 and January 2022, MAKO robotic-arm assisted THA via DAA was applied to treat 10 cases (12 hips) of AS with bony fused hips. There were 7 males and 3 females; the age ranged from 30 to 71 years, with an average age of 42.4 years. The duration of AS was 12-35 years, with an average of 21.4 years. The preoperative hip was ankylosed in flexion in 3 cases, with a flexion angle of 20°, 30°, 35°, respectively; 9 cases were ankylosed in extension. The operation time and complications were recorded; the visual analogue scale (VAS) score, Harris score, and Oxford hip scale (OHS) score before and after operation, and postoperative range of motion (flexion, extension, internal rotation, external rotation, adduction, and abduction) were used to evaluate the recovery of joint function; according to the postoperative anteroposterior X-ray film and CT scan of both hip joints, the abduction angle, anteversion angle, the difference between bilateral combined off-set and the lower limb length discrepancy were measured. Results The operation time ranged from 80 to 190 minutes (mean, 134.6 minutes). All 10 patients were followed up 5-11 months (mean, 7.4 months). There was no serious adverse events such as incision infection, deep vein thrombosis of lower extremities, hip redislocation, aseptic loosening of the prosthesis, or death. At 5 months after operation, the acetabular prosthesis angle of abduction was 37°-45° (mean, 40.3°), anteversion angle was 9°-20° (mean, 15.8°). The difference between bilateral combined off-set was 0-10 mm (mean, 4.3 mm); the lower limb length discrepancy was 0-12 mm (mean, 3.5 mm). At last follow-up, the average range of motion of the hip joint was 89.2° in flexion (range, 80°-100°), 1.7° in extension (range, –5°-10°), 7.1° in internal rotation (range, 0°-15°), 20.4° in external rotation (range, 10°-30°), 7.9° in adduction (range, 0°-20°), and 16.5° in abduction (range, 10°-25°). At last follow-up, the VAS score, Harris score, and OHS score significantly improved when compared with those before operation (P<0.05). ConclusionThe MAKO robotic-arm assisted THA via DAA can achieve satisfactory results in the treatment of AS with bony fused hip, which has the advantages of accurate prosthesis installation, soft tissue release, and less trauma during operation.
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.
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.
ObjectiveTo discuss the effectiveness of the modified Hueter direct anterior approach in treatment of Pipkin typeⅠ and Ⅱ femoral head fractures.MethodsBetween September 2014 and May 2016, 12 patients with Pipkin type Ⅰ and Ⅱ femoral head fractures were treated with the modified Hueter direct anterior approach. There were 8 males and 4 females, aged from 32 to 60 years (mean, 40.2 years). The disease causes included traffic accident injury in 9 cases and falling from height injury in 3 cases. According to Pipkin typing, 8 cases were rated as type Ⅰ and 4 cases as type Ⅱ. The interval of injury and admission was 2-28 hours (mean, 7.2 hours). Reduction was performed in all patients within 6 hours after admission, and then bone traction was given. The operation was performed in 3-7 days (mean, 4.3 days) after redution. The modified Hueter direct anterior approach was applied to expose and fix femoral head fractures by Herbert screws compressively. The operation time and intraoperative blood loss were recorded, and the effectiveness was evaluated according to the Thompson-Epstein scale at last follow-up.ResultsThe operation time was 80-130 minutes (mean, 97.5 minutes), and the intraoperative blood loss was 100-200 mL (mean, 130.2 mL). All fractures achieved anatomical reduction and successful fixation. All 12 patients were followed up 12-32 months (mean, 24.3 months). All patients achieved bone union in 15-20 weeks (mean, 16.3 weeks) and no wound infection, lateral femoral cutaneous nerve injury, osteonecrosis of the femoral head, or heterotopic ossification occurred. Traumatic arthritis occured in 3 patients. According to the Thompson-Epstein scale at last follow-up, the results were excellent in 5 cases, good in 5 cases, fair in 2 cases, and the excellent and good rate was 83.3%.ConclusionThe modified Hueter direct anterior approach has the advantages of clear anatomic structure, less trauma, and shorter operation time, and it can effectively expose and fix the Pipkin typeⅠ and Ⅱ femoral head fractures.
Objective To compare the early effectiveness between by anterior approach via Bikini incision and by OCM approach in the primary total hip arthroplasty (THA). Methods Between June 2015 and March 2016, 60 patients with ischemic necrosis of the femoral head who accorded with the inclusion criteria were chosen in the study, who were divided into 2 groups according to different surgical approaches. THA was performed on 30 patients by anterior approach via Bikini incision (group A), and on 30 patients by OCM approach (group B). There was no significant difference in age, gender, body mass index, side of affected hip, Steinberg stage of ischemic necrosis of femoral head, preoperative hemoglobin, preoperative Harris score, and preoperative visual analogue scale (VAS) between 2 groups (P>0.05). The operation time, length of incision, intraoperative blood loss, transfusion rate, starting time of straight leg raising exercise, starting time of active abduction of hip, hospitalization time, the incidence of limb length discrepancy, postoperative Harris score and VAS score were recorded and compared between 2 groups. Anteroposterior pelvic X-ray films were taken to measure acetabular abduction and acetabular anteversion. Results Primary healing of incision was obtained in all patients of 2 groups, and there was no significant difference in complication between 2 groups (χ2=0.144,P=0.704). All the patients of 2 groups were followed up 3 to 12 months, averaged 6 months. There was no significant difference in operation time, length of incision, intraoperative blood loss, transfusion rate, hospitalization time, and starting time of straight leg raising exercise between 2 groups (P>0.05). Group A was significantly shorter than group B in starting time of active abduction of hip (t=–4.591,P=0.000), and was significantly lower than group B in the incidence of limb length discrepancy (χ2=5.455,P=0.020). After operation, neither Harris score at 2 weeks, 6 weeks, 3 months, and 6 months nor VSA score at 24 hours and 6 weeks showed significant difference between 2 groups (P>0.05). The anteroposterior pelvic X-ray films showed that all the prostheses were in good position, and there was no femoral prosthesis subsidence, acetabular cup displacement or dislocation. No significant difference was found in acetabular abduction and acetabular anteversion at 2 days after operation between 2 groups (t=0.887,P=0.379;t=0.652,P=0.517). Conclusion Both of two approaches in THA can avoid muscle damage and achieve favorable short-term effectiveness. But, anterior approach via Bikini incision is superior to OCM approach in starting time of active abduction of hip and the incidence of limb length discrepancy.
