Objective To investigate cost-effectiveness of no indwelling urinary catheter in pulmonary lobectomy patients and to confirm the advances of no indwelling urinary catheter. Methods We recruited 148 lung cancer patients who were scheduled for pulmonary lobectomy under general anesthesia in West China Hospital from July through December 2015. These patients were divided into two groups including an indwelling urinary catheter group (74 patients, 45 males and 29 females, at age of 52.55±19.87 years) and a no indwelling urinary catheter group (74 patients, 42 males and 32 females, at age of 54.03±16.66 years). Indexes of cost-effectiveness of the two groups were compared. Results There was no statistical difference between the two groups in duration of indwelling catheter (1.56±0.0.65 d versus 1.68±0.91 d, P=0.077). Material expense(4 811.48 yuan versus 296.74 yuan, P=0.045), cost of nursing care (7 413.32 yuan versus 457.32 yuan, P=0.013), and total expense (12 224.8 yuan versus 754.06 yuan, P=0.000) in the indwelling catheter group were higher than those in the no indwelling catheter group. Material expense per patient (65.02±5.62 yuan/patient-time versus 4.01±0.00 yuan/patient-time, P=0.000), cost of nursing care per patient (100.18±7.19 yuan/patient-time versus 6.18±1.22 yuan/patient-time, P=0.000), and total cost per patient (165.20±12.81 yuan/patienttime versus 10.19±1.22 yuan/patient-time, P=0.000) in the indwelling catheter group were higher than those in the no indwelling catheter group. Conclusion Both costs and labor of nurse can be cut down for appropriate lung cancer patients undergoing lobectomy without routine indwelling urinary catheter.
ObjectiveTo compare the efficacy of photodynamic therapy (PDT) alone or in combined with ranibizumab versus ranibizumab monotherapy (intravitreal injection, IVR) in patients with polypoidal choroidal vasculopathy (PCV). Methods80 eyes of 72 patients with PCV were enrolled into this retrospective and comparative study according to their therapeutic plan. 30 eyes of 28 patients, 28 eyes of 30 patients and 22 eyes of 21 patients were divided into PDT group, ranibizumab 0.5 mg group (IVR group) or the combination group, respectively. The patients with PCV were diagnosed according to clinical symptoms, optical coherence tomography (OCT) and fluorescent indocyanine green angiography (ICGA). The baseline best-corrected visual acuity (BCVA) before treatment was more than 0.05, and there was no retinal fibrosis and scar for all patients. There was no statistical difference of age (F=0.187), gender (χ2=0.423), average BCVA (F=1.120) and central retinal thickness (CRT) (F=0.431) among three groups (P > 0.05). They had not received any treatment before. Patients received verteporfin PDT in PDT group, 3 consecutive monthly IVRs starting day 1 in IVR group, and 3 IVRs after 3 days, 1 month, 2 months of PDT starting day 1 in combination group. Re-treatment was considered 3 months later if the follow up shown no changes in fundus photography, OCT and ICGA. The average follow-up time was 19 months. BCVA at baseline and follow-up visit at 1, 3, 6, 12 months was measured, and the proportion of patients with ICGA-assessed complete regression of polyps at month 6 was recorded as primary outcome. The CRT was measured at baseline and 6 months as secondary outcome. ResultsThere were significant difference of BCVA at 1, 3, 6 and 12 months among three groups(F=5.480, 5.249, 3.222, 4.711; P < 0.05). The average BCVA was significantly better at 1, 3, 6, 12 month than that at baseline(t=-6.632, -4.127, -3.904, -4.494; P < 0.05) in combination group, and was significantly better at 3, 6, 12 months than that at baseline (t=-5.636, -3.039, -3.833; P < 0.05) in IVR group. However there was no significant difference of the average BCVA in PDT group between follow-up at 1, 3, 6, l 2 months and baseline (t=1.973, 0.102, -0.100, -0.761; P > 0.05). The proportion of patients with complete regression of polyps at 6 months was higher in PDT (76.7%) or combination group (68.2%) than IVR group (35.7%) (χ2=0.003, 0.025; P < 0.05). There was no significant difference of CRT among 3 groups at baseline (P=0.651). The mean CRT decreased in all 3 treatment groups over 6 months (t=5.120, 3.635, 5.253; P < 0.05), but there was no significant difference of CRT among 3 groups (F=1.293, P > 0.05). ConclusionsThree therapies could effectively decrease CRT. IVR or IVR combined with PDT are both more effective than PDT therapy to improve vision of PCV patients. PDT or PDT combined with IVR was superior to IVR pnly in achieving complete regression of polyps in 6 months in PCV patients.
ObjectiveTo assess the mid-term effectiveness of anterior cruciate ligament (ACL) revision and to analyze the relevant factors that may affect the surgical outcomes.MethodsThe clinical data of 24 patients who underwent ACL revision surgery between April 2009 and July 2018 and were followed up for more than 2 years were retrospectively analyzed. There were 20 males and 4 females with a median age of 30 years [interquartile distance (IQR) was (25, 36) years]. The median body mass index was 24.45 kg/m2 and IQR was (22.93, 25.93) kg/m2. The median time between ACL revision and reconstruction was 41 months and IQR was (15, 85) months. The direct cause of the failure of reconstruction surgery included 14 cases of trauma, 8 cases of no obvious cause, and 2 cases of infection. During the revision operation, 14 patients had a poor bone tunnel position, all of which were drilled with new tunnels, the remaining 10 patients were freshly modified on the basis of the original bone tunnel. Seventeen patients used autogenous tendon revision, 7 patients used LARS ligament; 16 patients had cartilage injury. The Lysholm score, the International Knee Documentation Committee (IKDC) score, and the Tegner sports rating score were used for functional evaluation before operation, at 1 year after operation, and at last follow-up. The Likert satisfaction score was recorded at last follow-up.ResultsPatients were followed up with a median time of 47 months and IQR was (32, 61) months. The Lysholm score, IKDC score, and Tegner sports rating score were significantly improved at 1 year after operation and at last follow-up when compared with preoperative scores (P<0.05). There was no significant difference between at last follow-up and at 1 year after operation (P>0.05). At last follow-up, the median Likert satisfaction score was 4.0 and IQR was (3.0, 4.5). According to the presence or absence of cartilage damage and the type of graft, the above scores at last follow-up were compared between the groups, and the differences were not significant (P>0.05). At last follow-up, 2 patients had graft fractures due to trauma again, and autogenous iliac bones were taken to fill the bone tunnel, and the second stage was revised; the rest of the patients recovered satisfactorily.ConclusionWith preoperative identification of the cause of ACL reconstruction failure, the stability and function of knee joint can be significantly improved by selecting appropriate bone tunnels and grafts during the revision and by active rehabilitation exercises.
ObjectiveTo evaluate the long-term effectiveness of lunate excision and vascularized capitate osteotomy transposition for advanced Kienböck's disease. MethodsBetween June 2004 and January 2008,16 patients with Kienböck disease in Lichtman stages ⅢB-IV were treated with lunate excision and vascularized capitate osteotomy transposition.There were 10 males and 6 females at the age of 27-59 years (mean,38.8 years).The disease was caused by trauma in 10 cases,and unknown reason in 6 cases.The main clinical symptoms were pain and limited activity of the wrist joint,and the disease duration was 5-32 months (mean,26.5 months).The carpal height index was 0.88±0.05; the radioscaphoid angle was (63.8±9.1)°.The visual analogue scale (VAS) score,range of motion (ROM),grip strength,Evans score,and radiographic changes were used to assess the effectiveness during follow-up. ResultsAll patients obtained healing of incision by first intention and were followed up 5 years and 4 months to 9 years (mean,5.8 years).VAS score was 2.0±1.5 at the final follow-up.The ROM of the flexion and extension of the wrist joint at the affected side were significantly less than those at the normal side (P<0.05).However,no significant difference was found in the grip strength and Evans score between the affected side and normal side (t=-0.997,P=0.327; t=-1.852,P=0.077).Postoperative radiographs showed that the carpal height index was 0.94±0.03,and the radioscaphoid angle was (48.4±4.8)°,which were improved significantly when compared with preoperative ones (t=-3.927,P=0.000; t=5.987,P=0.000).Osteophyte at the dorsal side of the radius and scaphoid rotation occurred in 6 cases and 2 cases,respectively. ConclusionLunate excision and vascularized capitate osteotomy transposition is a reliable method for advanced Kienböck's disease,with favorable improvement in wrist pain and grip strength for long-term follow-up.
ObjectiveTo evaluate the mid-term effectiveness of arthrolysis and hinged external fixation for the treatment of stiff elbow caused by heterotrophic ossification.MethodsBetween January 2014 and December 2017, 11 patients with stiff elbow caused by heterotrophic ossification were admitted. There were 9 males and 2 females with an average age of 32 years (range, 14-48 years), and left side in 6 cases and right side in 5 cases. The cause of stiff elbow included humerus fracture in 5 cases, ulna fracture in 2 cases, fracture of capitulum radii in 1 case, dislocation of capitulum radii in 1 case, terrible triad of the elbow in 1 case, and soft tissue injury in 1 case. The disease duration ranged from 7 to 18 months (mean, 11 months). Preoperative active range of motion of elbow was (19.6±17.5)° and Mayo score was 34.1±9.7. All patients received the treatment of arthrolysis and debridement of heterotrophic ossification lesion combining hinged external fixator, and active and passive rehabilitation with the help of hinged external fixator. The hinged external fixators were removed after 2 months.ResultsAll patients were followed up 13-36 months (mean, 19.1 months). All incisions healed by first intention, and no complication of infection or nerve lesion occurred postoperatively. At last follow-up, the results of X-ray films showed that no heterotrophic ossification recurred. The active range of motion of elbow was (116.4±16.6)° and Mayo score was 93.2±7.8, showing significant differences when compared with preoperative ones (t=17.508, P=0.000; t=16.618, P=0.000).ConclusionThe application of arthrolysis and debridement of heterotrophic ossification lesion combining hinged external fixator can improve the elbow’s range of motion significantly and obtain a good mid-term effectiveness.
ObjectiveTo explore the mid-term effectiveness of total hip arthroplasty (THA) with subtrochanteric shortening osteotomy in treatment of Crowe type Ⅳ developmental dysplasia of the hip (DDH).MethodsBetween September 2009 and March 2014, a total of 49 patients (57 hips) who were diagnosed with Crowe type Ⅳ DDH were treated with THA and subtrochanteric shortening osteotomy. Of the 49 patients, 7 were male and 42 were female with an average age of 44.6 years (range, 20-73 years). The preoperative Harris score was 44.68±3.39 and the preoperative leg length discrepancy was (5.27±0.55) cm.ResultsAll incisions healed primarily. All patients were followed up 32-87 months (mean, 52.1 months). At last follow-up, the Harris score was 85.67±2.89 and the leg length discrepancy was (1.12±0.48) cm, showing significant differences when compared with the preoperative values (t=–69.53, P=0.00; t=42.94, P=0.00). X-ray films showed that bone union of the femoral osteotomy end at 6 months after operation. There was no loosening and subsidence of prosthesis at last follow-up.ConclusionThe subtrochanteric shortening osteotomy with THA in treatment of Crowe type Ⅳ DDH can obtain satisfactory mid-term effectiveness with low risk of peripheral vascular and nerve traction injuries.
ObjectiveTo compare the results of internal limiting membrane (ILM) peeling with and without ILM transplantation to treat idiopathic macular hole (IMH) with hole form factor (HFF)<0.6. MethodsForty patients (40 eyes) of IMH with HFF<0.6 who underwent pars plana vitrectomy (PPV) were enrolled in this study. 20 eyes was performed PPV combined with ILM peeling (ILM peeling group), the other 20 eyes was performed PPV combined with ILM peeling and ILM transplant (ILM transplant group). The follow-up was ranged from 3 to 6 months with an average of 4 months. The changes of closing rate of hole, best corrected visual acuity (BCVA), photoreceptor inner segment/outer segment (IS/OS) junction defect diameter and amplitude of wave P1 of ring 1 and ring 2 by multifocal electroretinogram (mfERG) were comparatively analyzed for the two groups. ResultsIn 3 months after surgery, the IMH closing rate was 70% (14/20) in the ILM peeling group, and 100% (20/20) in the ILM transplant group, the difference between these two groups was significant (χ2=7.059, P<0.05). Postoperative BCVA was improved obviously in the two groups compared to preoperative BCVA, the difference was significant (t=4.017, 4.430; P<0.05). The rate of BCVA improvement in the ILM peeling group and ILM transplant group were 80% and 85%, the difference was not significant (χ2=0.173, P>0.05). The rate of significantly BCVA improvement in the ILM peeling group and ILM transplant group were 35% and 70%, the difference was significant (χ2=4.912, P<0.05). IS/OS junction defect (t=6.368, 6.635; P<0.05) and amplitude of wave P1 of ring 1 (t=2.833, 4.235) and ring 2 (t=2.459, 4.270) by mfERG in the two groups were improved after operation. The differences of postoperative IS/OS junction defect (t=2.261, P<0.05) and amplitude of wave P1 of ring 2 between the two groups were significant (t=2.282, P<0.05), but the differences of postoperative amplitude of wave P1 of ring 1 between two groups was not different (t=1.800, P>0.05). ConclusionPPV combined with ILM peeling and ILM transplantation can significantly improve the closure rate and vision of IMH with HFF<0.6.
ObjectiveTo investigate the short-term effectiveness of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treatment of anterior pelvic ring fractures. MethodsBetween January 2012 and October 2013, 16 patients with anterior pelvic ring fractures were treated with MIPPO. There were 10 males and 6 females at the age of 20-63 years (mean, 41 years). The causes of injury were traffic accident in 9 cases and falling from height in 7 cases. The duration of injury to admission was 2 hours to 5 days (mean, 1 day). According to Tile classification, 8 cases were rated as type B2, 4 cases as type B3, 2 cases as type C1, and 2 cases as type C2. Of them, 2 cases had iliac wing fracture, and 4 cases had pelvic posterior ring fracture. The time from admission to operation was 3-12 days (mean, 6 days). ResultsThe bleeding volume was 60-120 mL (mean, 70 mL). All wounds healed by first intention. No postoperative complication of deep venous thrombosis or long-term continuous pain occurred. All cases were followed up 5-27 months (mean, 11.5 months). No clinical manifestation of lateral femoral cutaneous nerve injury or spermatic cord injury was found, and cremasteric reflex existed in males. All cases obtained bony union, and the healing time was 12-16 weeks (mean, 13 weeks). During the follow-up period, no loss of fracture reduction and no internal fixation loosening or broken were observed. According to Matta radiological evaluation criterion, 16 cases had anatomical reduction, and 3 cases had satisfactory reduction; according to Majeed scoring system of pelvic fracture, the results were excellent in 12 cases and good in 4 cases. ConclusionMIPPO for treatment of anterior pelvic ring fractures has the advantages of less intraoperative blood loss, few soft tissue complications, and low infection rate, and can get satisfactory short-term effectiveness.
ObjectiveTo investigate the early effectiveness of arthroscopic repair of supraspinatus tendon tears with douple-pulley suture-bridge. Methods The clinical data of 38 patients with supraspinatus tendon tears who met the selection criteria between September 2020 and July 2022 were retrospectively analyzed, and all of them were treated with arthroscopic double-pulley suture-bridge technique. There were 15 males and 23 females, aged from 43 to 77 years, with an average of 61.5 years. There were 15 cases of left shoulder and 23 cases of right shoulder. Seven cases had a history of trauma, and the other 31 cases had no obvious inducement. The main clinical symptoms of the patient were pain in lifting the shoulder joint and hug resistance test (+). The time from onset of symptoms to admission ranged from 6 to 19 months, with an average of 10.3 months. Flexion, abduction, and external rotation of the shoulder were recorded before operation and at 3 and 12 months after operation. Pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, and American Society of Shoulder and Elbow Surgeons (ASES) score before operation and at 12 months after operation. Tendon healing, tendon continuity, and tension were evaluated by MRI at 3-6 months after operation, and patient’s satisfaction was evaluated at last follow-up. ResultsAll the incisions healed by first intention, and there was no complication such as incision infection or nerve injury. All patients were followed up 12-34 months, with an average of 23.3 months. VAS score, UCLA shoulder score, and ASES score at 12 months after operation were significantly better than those before operation (P<0.05). The external rotation range of shoulder joint significantly improved at 3 and 12 months after operation (P<0.05), and it further improved at 12 months after operation when compared with 3 months after operation (P<0.05). There was no significant difference in the range of flexion and abduction at 3 months after operation when compared with those before operation (P>0.05), but the range of flexion and abduction at 12 months after operation significantly improved when compared with those before operation and at 3 months after operation (P<0.05). MRI reexamination was performed in 28 patients at 3-6 months after operation. Among them, 25 patients had intact supraspinatus tendon structure, good tension, and tendon healing, and 3 patients had type 1 retear. The remaining 10 patients refused to undergo MRI reexamination because of the satisfactory effectiveness. At last follow-up, 29 patients (76.3%) were very satisfied with the results, 6 (15.7%) were satisfied, and 3 (7.8%) were not satisfied. ConclusionArthroscopic double-pulley suture-bridge technique can achieve the effect of suture bridge operation, reduce the cost of operation and the risk of type 2 retear, and the early effectiveness is satisfactory, but the shoulder joint movement is limited within 3 months after operation.
ObjectiveTo assess the mid-term effecitveness of femoroacetabular impingement (FAI) treated by surgical hip dislocation.MethodsBetween April 2014 and August 2015, 15 patients (16 hips) with FAI were enrolled in the study and treated with surgical hip dislocation. There were 12 males and 3 females with an average age of 36.6 years (range, 22-59 years). Among them, 14 cases involved in unilateral hip and 1 in bilateral hips. The mean disease duration was 28 months (range, 4-120 months). Preoperative visual analogue scale (VAS) score and Harris hip score were 7.9±1.0 and 44.1±9.3, respectively.ResultsAll incisions healed by first intention. There was no main complication, such as vessel and nerve injuries and infection. All 15 patients were followed up 30-46 months (mean, 39.5 months). The VAS score was 2.5±1.6 at 3 months and 0.5±0.7 at last follow-up. The Harris score was 85.5±4.4 at 3 months and 95.6±3.9 at last follow-up. There were significant differences in two scores between pre- and post-operation and between 3 months and last follow-up (P<0.05). The satisfaction rate of hip function was 93.8% (15/16) at last follow-up. X-ray examination showed that there was no sign of impingment at the femoral head and neck and acetabulum forming site of the affected hip joint, and no complication such as loosening of internal fixator, nonunion of osteotomy, avascular necrosis of femoral head, and heterotopic ossification occurred during follow-up.ConclusionThe surgical hip dislocation is a safe and effective way to treat FAI in the mid-term follow-up, which can repair torn labrum and trim acetabulum and femoral neck.
