Objective To detect the operative technique and aesthetic problem of reconstruction to deformity of bilateral cleft lip． Methods From March 2003 to December 2004, 26 patients with bilateral cleft lip were treated, aged 10 months to 11 years. Of 26 patients, there were 13 bilateral complete cleft lip and palate, 9 bilateral incomplete cleft lip and 4 mixed cleft lip with unilateral complete cleft palate. The chief design principle was keeping the length of prolabium. During operation, sufficient dissociation was made in the base of the ala base and orbicularis oris muscle to reconstruct these structures．The circle suture was made for the bilateral orbicularis oris muscle. The shape of vermilion was achieved by lateral red lip muscle flap and simultaneous simple rhinoplasty was performed. Results Primary healing of the incisions was achieved in all cases. After the 10 days-3 months follow-up, the results were satisfactory in thewidth and chubbiness of the nose bottom,the shapes of nostril and Cupid’s bow were good without whistle deformity. Theapperance of upper lip was good in either dynamic or static state． Conclusion Excellent shapes and function of the nose and lip， and opportunity for twostage repair could be obtained with this method，which being believed important methods for the primary repair of bilateral cleft lip．
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 investigate the effectiveness of modified Stoppa approach with medial wall spring plate (MWSP) for involving quadrilateral of acetabulum fracture. MethodsBetween March 2008 and September 2013, 38 patients with involving quadrilateral of acetabulum fracture were treated, including of 23 males and 15 females with an average age of 36.08 years (range, 19-56 years). The causes included traffic accidents injury (21 cases), crash injury of heavy object (10 cases), and falling injury from height (7 cases). The interval of injury and admission was 3 hours to 2 days (mean, 11 hours). There were 12 cases of anterior column fracture (type D), 5 cases of transverse fractures (type E), 8 cases of T shaped fractures (type H), 6 cases of anterior column fracture with posterior transverse fractures (type I), and 7 cases of double column fractures (type J) according to Letournel-Judet classification. Based on fracture types, MWSP was used to fix fracture by modified Stoppa approach in 19 cases or combined with the ilioinguinal approach in 10 cases or combined with Kocher-Langenbeck approach in 9 cases. The operation time, blood loss, and complications were recorded. The effectiveness of reduction and the hip function were evaluated according to Matta score system and Merled' Aubigne and Postel score system. ResultsThe operation time was 85-210 minutes (mean, 130 minutes).The intra-operative blood loss was 450-900 mL (mean, 650 mL). There were 1 case of vascular avulsion, and 1 case of bladder injury during operation; there were 8 cases of venous thrombosis and 2 cases of fat liquefaction of incision after operation. Screw was implanted into the articular joint in 1 case on CT after operation. Matta X-ray assessment showed anatomical reduction in 9 cases, satisfactory reduction in 24 cases, and unsatisfactory reduction in 5 cases, and the satisfaction rate of reduction was 86.84%. Three patients had limb shorting of 0.8-1.0 cm when compared with normal limb. All patients were followed up for 7 to 18 months with an average of 10 months. Fractures healed well within 13-16 weeks with an average of 14 weeks. At 1 year after operation, the results were excellent in 9 cases, good in 21 cases, general in 5 cases, and poor in 3 cases, and the excellent and good rate was 78.95% according to the Merled'Aubigne and Postel hip score standards. ConclusionInvolving quadrilateral of acetabulum fracture can be fixed with MWSP by modified Stoppa approach or combined with other approaches to obtain good exposure, less invasion, satisfactory reduction, stable fixation, and low complications.
ObjectiveTo investigate the early effctiveness of oblique lateral interbody fusion (OLIF) combined with pedicle screw fixation via small incision Wiltse approach for the treatment of lumbar spondylolisthesis.MethodsBetween January 2016 and December 2016, 21 patients with lumbar spondylolisthesis were treated with OLIF and pedicle screw fixation via small incision Wiltse approach. There were 9 males and 12 females, aged 57-73 years, with an average age of 64.5 years. The disease duration was 24-60 months, with an average of 34.6 months. All cases were spondylolisthesis at L4 (15 cases of degreeⅠ, 6 cases of degreeⅡ); 1 case had vertebral arch isthmus, and 20 cases had spinal stenosis. Japanese Orthopaedic Association (JOA) scoring system was used to evaluate the effectiveness before operation and at last follow-up. Before operation and at 2 days after operation, anteroposterior and lateral X-ray films and CT were taken to measure the sagittal diameter and cross-sectional area of the spinal canal, and calculate the intervertebral height and degree of spondylolisthesis. At 6 months after operation, the intervertebral fusion was evaluated by CT.ResultsThe operation time was 120-180 minutes, with an average of 155 minutes; the intraoperative blood loss was 100-340 mL, with an average of 225.5 mL. One patient had slight injury of lower endplate, 1 patient had numbness of thigh and weakness of hip flexion after operation, 1 patient had sympathetic nerve trunk injury. All the cases were followed up 12-18 months, with an average of 14.3 months. The symptoms of low back pain, leg pain, and numbness of lower limbs significantly relieved after operation, and there was no complication such as protrusion of fusion cage, screw breakage, and endplate collapse. At 2 days after operation, the intervertebral height, degree of spondylolisthesis, sagittal diameter of spinal canal, and cross-sectional area of spinal canal significantly improved compared with preoperative ones (P<0.05). At 6 months after operation, CT showed that 1 patient had poor interbody fusion (grade Ⅲ), the other 20 patients had good interbody fusion (grade Ⅰ and Ⅱ), and the interbody fusion rate was 95.2%. At last follow-up, JOA score of lumbar spine significantly increased compared with that before operation (t=24.980, P=0.000).ConclusionOLIF combined with pedicle screw fixation via small incision Wiltse approach for the lumbar spondylolisthesis has minimally invasive features, such as less trauma, fewer complications, and higher intervertebral fusion rate. It is a safe and effective method.
ObjectiveTo summarize the clinical application of the minimally invasive step-up approach in the treatment of severe acute pancreatitis (SAP), and to explore the clinical indications, timing for the minimally invasive step-up approach, and to make comparison with open necrosectomy. MethodsThe literatures about the treatment of SAP in recent years were collected to make a review. ResultsThe minimally invasive step-up approach, comparing with open necrosectomy, was more effective to treat SAP, however, itself had its own limitations. In the treatment process, the optimal method was minimally invasive step-up approach, but also did not exclude open necrosectomy. ConclusionsThe treatment of SAP can not rely on a single method, it needs a comprehensive treatment which is relate with multidisciplinary management and highly individual choice. In addition, it needs further study to explore the timing and indications for transforming minimally invasive step-up approach into open necrosectomy.
ObjectiveTo evaluate the early effectiveness of the robot-assisted total hip arthroplasty (THA) via direct superior approach (DSA).MethodsBetween March 2021 and April 2021, 11 patients (11 hips) were treated with a robot-assisted THA via DSA. There were 7 males and 4 females, with an average age of 55 years (range, 26-73 years). There were 5 patients of osteoarthritis secondary to hip dysplasia and 6 patients of osteonecrosis of femoral head. Preoperative hip Harris score was 55.8±6.3. The operation time, volume of blood loss, length of incision, postoperative blood transfusion and hospital stay, and the incidence of surgical complications were recorded. The visual analogue scale (VAS) score and Harris score were used to evaluate hip joint pain and function. The leg length discrepancy (LLD) was measured on the X-ray films. The inclination angle and anteversion angle of the acetabular component were also measured, and the difference between the planned and actual values were compared.ResultsOne THA was performed via conventional posterolateral approach finally because of poor exposure. The rest of 10 THAs were performed with assistance of robotic arm via DSA. The average operation time was 89 minutes (range, 65-120 minutes); the average length of incision was 10.5 cm (range, 9-13 cm); and the average blood loss was 400 mL (range, 110-740 mL). One patient was given a blood transfusion for 2 unit. All incisions healed by first intention and no neurovascular injury, deep vein thrombosis, or fracture occurred. The length of hospital stay after operation was 2-6 days (mean, 4.4 days). The duration of follow-up was 1-3 months (mean, 2.1 months). The VAS score was 0 in 9 patients and 2 in 1 patient at the day of discharge. At last follow-up, the hip Harris score was 84.9±6.7, showing significant difference when compared with that before operation (t=−8.717, P=0.000). The inclination and anteversion angles were (37.4±2.0)° and (17.1±4.5)°, respectively, and there was no significant difference when compared with the planned values [(38.2±1.6)°, (16.6±3.7)°] (t=1.809, P=0.104; t=–1.103, P=0.299). The LLD ranged from –2 to 4 mm. No complication such as dislocation, aseptic loosening, or periprosthetic joint infection occurred. ConclusionThe robot-assisted THA via DSA has encouraged early effectiveness.
Objective To evaluate the effect of the modified extended iliofemoral approach on treatingcomplex acetabular fractures. Methods Thirty-six cases of complex acetabular fractures were treated by the open reposition and internal fixation by a modified extended iliofemoral approach. Results Thirty-sixcases were followed up for 7-46 months, with an average of 23.8 months. According to the Matta standard, anatomical reposition was performed in 24 cases, perfect reposition in 8 cases, and unsatisfactory reposition in 4 cases. By the modified d’Aubignepostel score, among the 36 cases, 22 had an excellent result, 9 had a good result, and 5 had a poor result. Conclusion Themodified extended iliofemoral approach facilitates the operative exposure of the anterior and posterior walls and both columns of the acetabulum in the surgically-treated acetabular fractures by the open reposition and internal fixation.Because of the reconstruction, the functions of the abductor muscle mass managed by the lagscrew-fixed osteotomies of the iliac crest, and greater trochanter, the patients can achieve a rapid rehabilitation of the joint.
To evaluate the efficacy and the surgical procedures of submandibular sialoadenectomy by a modified retroauricular approach. Methods Between October 2008 and April 2009, 8 patients with benign submandibular gland disorders underwent removal of benign submandibular gland lesions using a retroauricular approach. There were 4 males and 4 females with an average age of 38.5 years (range, 32-54 years), including 3 pleomorphic adenoma and 5 chronic sialadenitis with sialol ithiasis. The disease duration was from 2 months to 5 years. The anterior facial vein and the facial artery were reserved only by the l igation of branching vessels in the submandibular gland. Results Submandibular sialoadenectomy were successfully performed in 8 cases. The operative time was 45-75 minutes (mean, 60 minutes). All incisions obtained heal ing by first intention. No nerve paralysis occurred, including marginal mandibular branch of the facial nerve, the l ingual nerve, and hypoglossal nerve. One patient had poor blood circulation of flap due to excessive traction during operation, but it returned normal after 24 hours without special treatment. Other flaps had good blood circulation. All patients were followed up 1-6 months (mean, 3 months). The incision scars were hidden with satisfactory appearance. Conclusion The modified retroauricular approach has some advantages such as simple operation, better cosmetic outcome, and no compl ication.
ObjectiveTo discuss the value of surgical hip dislocation approach in the treatment of femoral head fracture. MethodsA retrospectively analysis was made on the clinical data of 15 patients with femoral head fractures treated through surgical hip dislocation approach between January 2010 and February 2013. There were 11 men and 4 women with an average age of 30.8 years (range, 15-63 years). The causes included traffic accident injury in 9 cases, falling injury from height in 5 cases, and sports injury in 1 case. According to Pipkin typing, 2 cases were rated as type Ⅰ, 7 cases as type Ⅱ, 1 case as type Ⅲ, and 5 cases as type Ⅳ. The interval of injury and operation was 2-10 days (mean, 4.1 days). Reduction was performed in 10 patients within 6 hours after injury, and then bone traction was given for 4-6 weeks except 5 patients who received reduction in the other hospital. ResultsPrimary healing of incision was obtained in all patients after surgery without complications of dislocation and lower limbs deep venous thrombosis. The mean follow-up time was 29.9 months (range, 25-36 months). During follow-up, there was no infection, breakage of internal fixation, or nonunion of femoral greater trochanter fracture. In 3 patients having necrosis of the femoral head, 2 had no obvious symptoms[staging as Ⅱa and Ⅱb respectively according to Association Research Circulation Osseous (ARCO) staging system], and 1 (stage Ⅲb) had nonunion of the femoral neck fracture, who underwent total hip arthroplasty (THA). In 4 patients having myositis ossificans (2 cases of grade Ⅰ, 1 case of grade Ⅱ, and 1 case of grade Ⅲ based on Brooker grading), no treatment was given in 3 cases and the focus was removed during THA in 1 case. According to the Thompson-Epstein scale at last follow-up, the results were excellent in 9 cases, good in 3 cases, fair in 1 case, and poor in 2 cases, and the excellent and good rate was 80%. ConclusionSurgical hip dislocation approach can not only protect the residual vessels of the femoral head but also fully expose the acetabulum and femoral head, which is the ideal approach for the treatment of femoral head fractures.
ObjectiveTo evaluate the feasibility and effectiveness of proximal femoral nail anti-rotation (PFNA) combined with curettage and bone graft through Watson-Jones approach in the treatment of proximal femur benign tumors and tumor like lesions.MethodsThe clinical data of 38 patients with benign tumors and tumor like lesions in the proximal femur who were treated through the Watson-Jones approach with PFNA combined with curettage and bone graft between January 2008 and January 2015 were retrospective analysed. There were 24 males and 14 females with an average age of 28 years (range, 15-57 years). Pathological types included 20 cases of fibrous dysplasia, 7 cases of bone cyst, 5 cases of aneurysmal bone cyst, 3 cases of giant cell tumor of bone, 2 cases of enchondroma, and 1 case of non-ossifying fibroma. Before operation, hip pain occurred in 19 patients, pathological fracture occurred in 12 patients, limb shortening and coxa varus deformity was found in 4 patients, and 3 patients received surgery for the local recurrence. The operation time, intraoperative blood loss, and full-weight bearing time after operation were recorded. Patients were followed up to observe union of bone graft and the position of internal fixator on X-ray films and CT images. Visual analogue scale (VAS) score was used to evaluate the level of pain. The Musculoskeletal Tumor Society (MSTS93) score was used to evaluate lower limb function. Harris hip score was used to evaluate hip joint function.ResultsThe operation time was 130-280 minutes (mean, 182 minutes) and the intraoperative blood loss was 300-1 500 mL (mean, 764 mL). After operation, 3 cases of fat liquefaction of incision healed successfully by carefully dressing, and the rest incisions healed by first intention. All patients started partially weight-bearing exercise at 2-4 weeks after operation. The total weight-bearing time was 3-6 months (mean, 4.2 months). All the patients were followed up 24-108 months (median, 60 months). Imaging examination showed that the bone graft fused and the fusion time was 8-18 months (mean, 11.4 months). During the follow-up period, there was no complication such as pathological fracture, femoral head ischemic necrosis, hip joint dislocation, internal fixation loosening and fracture, and no tumor recurrence or distant metastasis occurred. At last follow-up, the VAS score, MSTS93 score, and Harris score were significantly improved when compared with preoperative ones (P<0.05).ConclusionThe treatment of proximal femoral benign lesions by PFNA combined with curettage and bone graft through the Watson-Jones approach is safe and effective, with advantages of better mechanical stability, less residual tumor, and less postoperative complications.
