Objective To investigate the effectiveness of arthroscopic double fixation and enhanced suture of long head of biceps tendon (LHBT) in situ for repairing rotator cuff tear. Methods A retrospective analysis was conducted on 31 patients with rotator cuff tears and LHBT injuries admitted between June 2022 and November 2023. All patients underwent arthroscopic double fixation and enhanced suture of LHBT in situ. There were 12 males and 19 females, with an average age of 61.6 years (range, 53-76 years). There were 10 cases of acute injury and 21 cases of chronic injury. According to DeOrio and Cofield classification criteria, the degree of rotator cuff tear rated as medium-sized tears in 3 cases, large tears in 12 cases, and massive tears in 16 cases. Associated injuries included 5 cases of shoulder joint adhesions, 12 cases of subscapularis muscle tears, and 31 case of shoulder impingement syndromes. The shoulder range of motion (ROM) (forward flexion, abduction, lateral external rotation, lateral internal rotation) and pain/function scores [visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, Constant-Murley score] were recorded before operation and at last follow-up. MRI at last follow-up were taken to evaluate the rotator cuff healing and structural integrity. Results All 31 surgeries were successfully completed with operation time ranging from 90 to 210 minutes (mean, 144 minutes). The 3-5 anchors (mean, 3.8 anchors) were used during operation. All incisions healed by first intention. All patients were followed up 12-29 months (mean, 18.5 months). At 3 months after operation, 2 cases developed joint adhesions, 3 had internal rotation limitations, and 2 experienced residual pain at the intertubercular groove, all resolved with conservative management. No Popeye deformity occurred during follow-up. At last follow-up, shoulder ROM (forward flexion, abduction, lateral external rotation, lateral internal rotation) and pain/function scores (VAS, UCLA, and Constant-Murley scores) showed significant improvements compared to preoperative values (P<0.05). At last follow-up, MRI evaluation showed that the rotator cuff healing rate reached 90.3% according to the Sugaya classification criteria. LHBT exhibited normal morphology, course, and continuity without dislocation. Surrounding synovial sheath showed no thickening or effusion. Conclusion Arthroscopic double fixation and enhanced suture of LHBT in situ for repairing rotator cuff tear can significantly reduce shoulder joint pain, improve ROM, and achieve a high rotator cuff healing rate.
ObjectiveTo study feasibility of sheath technique with seromuscular sleeve of pedicled colon in preventing anastomotic leakage following laparoscopic anterior resection of rectal cancer.MethodsThe clinical data of patients who underwent laparoscopic anterior resection of rectal cancer in our hospital from January 2017 to March 2020 were retrospectively collected. According to different surgical methods, they were divided into two groups: pedicled seromuscular sleeve sheath group (referred to as sleeve sheath operation group) and traditional operation group. The intraoperative and postoperative statuses were compared between these two groups.ResultsIn this study, 87 patients with rectal cancer were included, 37 in the sleeve sheath operation group and 50 in the traditional operation group. There were no significant differences in the baseline data such as the gender, age, body mass index (BMI), complicating disease, distance from lower tumor margin to anal verge, histological classification, neoadjuvant radio- chemotherapy, and TNM stage between the two groups (P>0.05). There were no significant differences in the volumes of intraoperative blood loss, the number of lymph node dissection, the first postoperative anal exhaust time and the hospitalization expense between the two groups (P>0.05). Compared with the traditional operation group, the operative time of the sleeve sheath operation group was longer (P<0.05), the postoperative hospitalization time of the sleeve sheath operation group was shorter (P<0.05). The incidence of postoperative anastomotic leakage in the sleeve sheath operation group and the traditional group were 0.0% (0/37) and 12.0% (6/50), respectively, and the difference was statistically significant (P<0.05). There were no significant differences in the anastomotic stenosis, the lymphatic fistula and the incision infection between the two groups (P>0.05). All patients were followed-up for 6 to 36 months, with a median time of 21 months. No recurrence or death occurred.ConclusionThe sheath technique with seromuscular sleeve of pedicled colon can increase the anti tension ability of anastomotic stoma and reduce the incidence of anastomotic leakage, which is a safe and effective surgical method.
Objective To study feasibility of sheath technique with seromuscular sleeve of pedicled colon in preventing anastomotic leakage following radical resection of rectal cancer. Method The clinical data of 11 patients with rectal cancer underwent the Dixon plus sheath technique with seromuscular sleeve of pedicled colon from January 2017 to October 2017 in the PLA Navy Anqing Hospital were analyzed. Results All the operations were completed successfully in the 11 patients with rectal cancer, including 9 cases of laparoscopy and 2 cases of laparotomy. The operative time was (255.5±51.5) min, the intraoperative bleeding was (80.0±28.3) mL, the first postoperative anal exhaust time was (4.4±2.0) d, the postoperative hospitalization time was (16.0±3.1) d. For the postoperative pathology, there were 5 cases of T4 stage, 2 cases of T3 stage, 2 cases of T2 stage, and 2 cases of T1 stage. The number of lymph node dissection was 5–23 with an average of 12.5 per case, 7 cases with lymph node metastasis. One case of lymphatic leakage and 1 case of incision infection occurred, and no anastomotic leakage and narrow occurred. After 3–10 months of follow-up (average follow-up 7 months), no local recurrence and distant metastasis were found. Conclusion Sheath technique with seromuscular sleeve of pedicled colon in preventing anastomotic leakage following radical resection of rectal cancer is feasible.
ObjectiveTo investigate the effectiveness of Endobutton plate coracoclavicular fixation combined with fracture site high-strength suture Nice knot cerclage fixation in the treatment of distal clavicle fracture with coracoclavicular ligament injury. Methods The clinical data of 33 cases of distal clavicular fracture with coracoclavicular ligament injury treated by Endobutton coracoclavicular plate fixation between January 2017 and December 2020 were analyzed retrospectively. According to the fixation methods of fracture site, they were divided into two groups: the high-strength suture Nice knot fixation group (study group, 16 cases) and the transacromial Kirschner wire fixation group (control group, 17 cases). There was no significant difference between the two groups in common data such as age, gender, injury side, cause of injury, Craig type, combined injury, time from injury to operation, and preoperative visual analogue scale (VAS) score and Constant-Murley score (P>0.05). Postoperative fracture healing and complications were observed, and the increase rate of coracoclavicular space on the affected side was calculated at last follow-up. VAS score was used to evaluate shoulder pain before operation, at 1 week, 1 month, 3 months after operation, and at last follow-up. The shoulder function was evaluated according to Constant-Murley shoulder score before operation, at 1 month, 3 months after operation, and at last follow-up. Results The operations were successfully completed in both groups without severe complications such as vascular nerve injury and coracoid fracture. In the control group, 1 case (5.9%) had slight pin tract infection and 1 case (5.9%) had Kirschner wire displacement; there was no obvious complication in the study group. The patients in both groups were followed up 9-36 months (mean, 22.9 months). The fracture healing time of the study group and the control group were (12.56±0.73) weeks and (13.59±0.87) weeks, respectively, and the difference was significant (t=−3.661, P=0.001). At last follow-up, the increase rates of coracoclavicular space on the affected side of the study group and the control group were 8.88%±1.19% and 8.55%±1.07%, respectively, showing no significant difference (t=0.837, P=0.409). The postoperative VAS score and Constant-Murley score of the two groups significantly improved when compared with those before operation, and the two scores gradually improved with the extension of time after operation (P<0.05). Except that the VAS score at 1 week and 1 month after operation and the Constant-Murley score at 1 month after operation in the study group were significantly better than those in the control group (P<0.05), there was no significant difference between the two groups at other time points after operation (P>0.05). Conclusion For oblique fracture or combined with butterfly fracture in the distal clavicle fracture with coracoclavicular ligament injury, the fracture site high-strength suture Nice knot fixation is a good supplement to the Endobutton plate coracoclavicular fixation. It can stabilize the fracture end, reduce the complications of Kirschner wire fixation, and is more conducive to fracture healing. The effectiveness is satisfactory.
Objective To investigate the effectiveness of arthroscopic long head of biceps tendon (LHBT) transposition combined with Swivelock anchor double fixation in treatment of massive and irreparable rotator cuff tears. Methods Between June 2019 and November 2021, 25 patients with massive and irreparable rotator cuff tears were treated by arthroscopic LHBT transposition combined with Swivelock anchor double fixation. There were 12 males and 13 females. The age ranged from 47 to 74 years (mean, 62.4 years). The disease duration ranged from 1 to 62 months (median, 7 months). The rotator cuff tears were classified as Hamada grade 2 in 25 cases and Goutallier grade 1 in 2 cases, grade 2 in 22 cases, and grade 3 in 1 case. Pre- and post-operative shoulder range of motion (ROM), visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, and Constant-Murley score were recorded. Postoperative complications were observed. The reconstructed tissue integrity was confirmed by MRI. Results All operations were successfully completed. The operation time was 120-330 minutes (mean, 189.6 minutes). All incisions healed by first intention. All patients were followed up 10-36 months (mean, 22.0 months). At last follow-up, the ROM in forward flexion, abduction, and external rotation, VAS score, UCLA score, and Constant-Murley score were superior to those before operation, and the differences were significant (P<0.05). According to UCLA scoring standard, shoulder joint function was rated as excellent in 5 cases, good in 18 cases, and poor in 2 cases, with an excellent and good rate of 92.0%. No other complications occurred except shoulder joint adhesion in 2 cases. At last follow-up, MRI examination showed no retear of rotator cuff, and LHBT was intact. Conclusion For massive and irreparable rotator cuff tears, arthroscopic LHBT transposition combined with Swivelock anchor double fixation can increase the force of pressing the humeral head, effectively relieve the pain, improve the ROM of joints, maximize the recovery of shoulder function, and do not increase the number of anchor nails.
