ObjectiveTo summarize the current status and progress of surgical treatment for postoperative recurrent hepatocellular carcinoma (HCC).MethodThe literatures about studies of surgical treatment of postoperative recurrent HCC were reviewed.ResultsThe surgical operation was an effective method for the treatment of recurrent HCC. The operation methods included re-hepatectomy and salvage liver transplantation. There was no uniform standard for the indication of re-hepatectomy, but the basic principles were the same. At present, the indication of salvage liver transplantation was mainly based on Milan criteria. For patients with recurrent HCC who met the operation indications, surgical operation could improve the long-term survival rate of patients and benefit the patients.ConclusionIt migh prolong the survival time and improve the long-term survival rate of patients with recurrent HCC when the appropriate patients and reasonable surgical methods are chosen according to the surgical indications, the tumor situation of initial hepatectomy, postoperative recurrence time, and other factors.
ObjectiveTo evaluate the operability and effectiveness of a self-developed patellar bone canal locator (hereinafter referred to as “locator”) in the reconstruction of the medial patellofemoral ligament (MPFL). Methods A total of 38 patients with recurrent patellar dislocation who met the selection criteria admitted between January 2022 and December 2022 were randomly divided into study group (the patellar canal was established with a locator during MPFL reconstruction) and control group (no locator was used in MPFL reconstruction), with 19 cases in each group. There was no significant difference in baseline data between the two groups (P>0.05), such as gender, age, body mass index, disease duration, patella Wiberg classification, constituent ratio of cartilage injury, Caton index, tibia tubercle-trochlear groove, and preoperative Lysholm score, Kujal score, Tegner score, visual analogue scale (VAS) score, and so on. The Lysholm score, Kujal score, Tegner score, and VAS score were used to evaluate knee joint function before operation and at 3 days,1 month, 3 months, and 6 months after operation. The ideal prepatellar cortical thickness and canal length were measured before operation, and the actual prepatellar cortical thickness and canal length after operation were also measured, and D1 (the distance between the ideal entrance and the actual entrance), D2 (the ideal canal length minus the actual canal length), D3 (the ideal prepatellar cortical thickness minus the actual prepatellar cortical thickness) were calculated.ResultsPatients in both groups were followed up 6-8 months (mean, 6.7 months). The incision length and intraoperative blood loss in the study group were smaller than those in the control group, but the operation time was longer than that in the control group, the differences were significant (P<0.05). There was no complication such as incision infection, effusion, and delayed healing in both groups, and no further dislocation occurred during follow-up. One patient in the study group had persistent pain in the anserine area after operation, and the symptoms were relieved after physiotherapy. The VAS score of the two groups increased significantly at 3 days after operation, and gradually decreased with the extension of time; the change trends of Lysholm score, Kujal score, and Tegner score were opposite to VAS score. Except that the Lysholm score and Kujal score of the study group were higher than those of the control group at 3 days after operation, and the VAS score of the study group was lower than that of the control group at 3 days and 1 month after operation, the differences were significant (P<0.05), there was no significant difference in the scores between the two groups at other time points (P>0.05). Patellar bone canal evaluation showed that there was no significant difference in preoperative simulated ideal canal length, prepatellar cortical thickness, and postoperative actual canal length between the two groups (P>0.05). The postoperative actual prepatellar cortical thickness of the study group was significantly smaller than that of the control group (P<0.05). D1 and D3 in the study group were significantly higher than those in control group (P<0.05), but there was no significant difference in D2 between the two groups (P>0.05). ConclusionThe locator can improve the accuracy of MPFL reconstruction surgery, reduce the possibility of intraoperative damage to the articular surface of patella and postoperative patellar fractures.
Objective To analyze the clinical features， common etiologies， prevention measurements of recurrent acute pancreatitis （AP）. Methods The clinical characteristics and imaging examination data of 43 patients with recurrent AP were analyzed retrospectively， which was compared with the results of 258 patients with primary AP. The recurrence etiologies were analyzed. Results There were no significant differences on the fever， jaundice， abdominal pain relief time， pancreatic local complications， and ratio of severe AP between two groups （P＞0.05）. Comparion of etiologies between recurrent AP and primary AP， cholecystitis and diet factor （alcoholic） had priority in patients with primary AP （P=0.038， P=0.006， respectively）， but the hyperlipidemic， duodenal nipple disease， and small stone in the common bile duct were the major etiologies in patients with recurrent AP （P=0.007， P=0.008， respectively）. No relapse was found within the follow up for 3 months to 2 years （the average time was 14.2 months）. Conclusion Find out the exact etiology and performe correct therapy are the key to the treatment and prevention of recurrent AP.
Objective To evaluate the early-term effectiveness of Latarjet procedure with double EndoButtons fixation for recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament. Methods Between January 2021 and June 2023, 19 patients with recurrent anterior shoulder dislocations were treated by arthroscopic Latarjet procedure with double EndoButtons fixation, all of which underwent coracoid osteotomy with preserving the coracoacromial ligament. There were 11 males and 8 females, with an average age of 23.3 years (range, 17-32 years). Shoulder dislocations ranged from 3 to 11 times, with an average of 6.4 times. The disease duration ranged from 3 to 35 months, with an average of 12.9 months. All apprehension tests were positive. Imaging examination showed that the defect width of the ipsilateral glenoid bone was 13%-26%, with an average of 19.8%. After operation, the shoulder range of motion was examined, including flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation. Shoulder joint function was evaluated by Walch-Duplay score, American Association for Shoulder and Elbow Surgery (ASES) score, and Rowe score. Imaging examinations were taken to observe the position and shaping of coracoid. Results All incisions healed by first intention and no nerve or vessel injury occurred. All patients were followed up 9-24 months (mean, 14.5 months). There was no recurrence of shoulder dislocation and the apprehension tests were negative during follow-up. There was no significant difference in the shoulder range of motion (flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation) between preoperation and at last follow-up (P>0.05). The Walch-Duplay score, ASES score, and Rowe score significantly improved when compared with those before operation (P<0.05). Postoperative imaging showed that coracoid graft was at the same level with the glenoid in all cases; the center of coracoid graft was located between 3 to 5 o’clock. During follow-up, there was no glenohumeral joint degeneration, the acromiaohumeral distance was not reduced when compared with preoperation, and the coracoid bone gradually formed concentric circles with the humeral head. Conclusion The Latarjet procedure with double EndoButtons fixation can effectively treat recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament, and the early-term effectiveness is satisfactory.
Objective To improve the knowledge on dynamic benign central airway stenosis through two typical cases. Methods The clinical features, imaging findings, and bronchial morphologic changes of two cases characterized by dynamic benign central airway stenosis were retrospectively analyzed. The etiologies for the two cases were tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC), respectively. Results Central airway stenosis and reversible airway obstruction were common clinical characteristics for the two cases. However, there were identifiable differences on imaging findings and bronchial morphologic changes between the two cases. Multidetector computed tomography showed sabre-sheath trachea and narrowed trachea in coronal position for TBM, while small sized trachea in exhalation phase and narrowed trachea in sagittal position for EDAC. Bronchoscopy displayed narrowed airway, swelling mucosa, and the absence of annular cartilage for TBM, while crescent airway with membranacea part protruding to lumen in inspiration phase, and the integrity of annular cartilage for EDAC. Conclusion Multidetector computed tomography and bronchoscopy examinations are valid methods to distinguish TBM and EDAC, which are both characterized by dynamic benign central airway stenosis.
