Objective To observe the therapeutic effect of autologous neurosensory retinal transplantation in repairing unhealed giant macular hole after pars plana vitrectomy (PPV). MethodsA prospective clinical study. From July 2022 to December 2023, 12 patients (12 eyes) with refractory large macular hole who received autologous neurosensory retinal transplantation treatment in Department of Ophthalmology of the First Affiliated Hospital of Zhengzhou University were selected for the study. The macular hole in affected eyes still did not close after PPV combined with inner limiting membrane removal or tamponade, and the diameter of macular hole were greater than 600 μm. All affected eyes received best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examinations. The BCVA examination employed the international standard visual acuity chart, with results converted to logarithm of the minimum angle of resolution (logMAR) visual acuity for statistical analysis. During the surgery, a piece of healthy retinal neuroepithelial tissue, approximately 0.3 optic disc diameters larger than the macular hole, was removed from the upper retinal periphery and used as a graft. The graft was inserted into the macular hole with the aid of intraoperative OCT. Post-surgery, the vitreous cavity was filled with silicone oil or sterile air. The follow-up period after surgery was 6 months. The thickness of the retinal grafts was measured using the same equipment as before surgery at 3 days, 1, 3, and 6 months post-surgery. The primary focus was on observing the macular hole closure rate and changes in BCVA at 6 months post-operation. A paired t-test was used to compare BCVA before and after surgery. Results In the sample of 12 cases (12 eyes), there were 5 males with 5 eyes and 7 females with 7 eyes. The mean age was (50.4±12.6) years. The mean macular hole diameter was (1 085.6±344.0) μm; The mean eye axis length was (27.64±4.19) mm. At 6 months after surgery, all affected eyes showed macular hole were completely closed (100.0%, 12/12). The thickness of the retinal graft was measured as (206.8±21.0), (170.8±23.3), (165.6±31.6), and (157.9±31.1) μm at 3 days, 1, 3, and 6 months post-surgery, respectively. At before and 6 months after surgery, the logMAR BCVA of the affected eyes was 1.28±0.39 and 0.95±0.22, respectively. The difference in logMAR BCVA before and after surgery was statistically significant (t=3.40, P＜0.05). Conclusion Autologous neurosensory retinal transplantation could effectively improve the closure rate of refractory large macular hole and improve or stabilize vision in the short run.
ObjectiveTo evaluate the effectiveness of the combined tenodesis for proximal lesions of biceps tendon with massive rotator cuff tear by arthroscopy.
MethodsBetween January 2011 and June 2013, 48 patients with massive rotator cuff tear and proximal lesions of biceps tendon underwent combined tenodesis under arthroscopy, and the clinical data were retrospectively analyzed. Of 48 cases, 22 were male and 26 were female with an average age of 46 years (range, 35-59 years); 12 cases had clear history of trauma. The disease duration ranged from 1 to 57 months (mean, 4.6 months). All cases suffered from moderate to severe shoulder pain, the strength and the range of motion (ROM) declined when compared with those of the other side. According to Goutallier classification standard, 3 cases were rated as grade 0, 18 cases as grade 1, and 27 cases as grade 2. The operation time and complication were recorded. The visual analogue scale (VAS) score, ROM, the strength of flexed elevation and elbow flexion, Constant-Murley score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, Mayo elbow performance score (MEPS) were used to evaluate the effectiveness.
ResultsThe operations were performed successfully, and incisions healed primarily. The operation time was 120-160 minutes (mean, 135 minutes). One case had shoulder joint swelling with wound bleeding, which was cured after proper treatment. All 48 patients were followed up 12-18 months (mean, 13.9 months). The results of MRI showed good healing of tendon at 6 months after operation. When compared with preoperative values, VAS score was significantly decreased (P<0.05); the ROM in forward flexion, external rotation, and internal rotation, and the strength of flexed elevation were significantly increased (P<0.05); and ASES score, Constant-Murley score, and UCLA score were significantly improved at 12 months after operation (P<0.05). No significant difference was observed in MEPS score and elbow flexion strength (P>0.05).
ConclusionThe technique of combined tenodesis under arthroscopy can obtain satisfactory clinical outcomes in treating proximal lesions of biceps tendon with massive rotator cuff tear.
Objective To review the progress in the treatment and research of massive rotator cuff tears. Methods Recent l iteratures about the treatment and research of massive rotator cuff tears were reviewed. Results Treatment options of massive rotator cuff tears include nonoperative treatment, debridement, direct repair, tendon transfer, and repair with various substitutes, but the outcome is unpredictable. Recently, many experimental studies on the treatment of massive rotator cuff tears, such as gene therapy, cell therapy, and tissue engineering techniques, can provide cl inicians with new treatment strategies. Conclusion The treatment of massive rotator cuff tears pose a distinct cl inical challenge for the orthopaedist, depending on the overall presentation. The effect of traditional operation method to repair massive rotator cuff tears is limited. The treatment and research of massive rotator cuff tears still need to be studied.
ObjectiveTo investigate early effectiveness of arthroscopic superior fulcrum reconstruction in the treatment of irreparable massive rotator cuff tear (IMRCT). Methods A retrospective analysis was conducted on the clinical data of 24 patients with IMRCT who met the inclusion criteria between January 2020 and April 2022. Among them, there were 11 males and 13 females with an average age of 56.2 years (range, 42-68 years). There were 12 cases of falling injuries, 3 cases of traction injuries, and the other 9 cases had no obvious causes. The disease duration ranged from 1 to 25 months (median, 6 months). The rotator cuff tears were classified as Hamada grade 2 in 18 cases and grade 3 in 6 cases, and Goutallier grade 1 in 3 cases, grade 2 in 20 cases, and grade 3 in 1 case. All patients were treated with arthroscopic superior fulcrum reconstruction. Visual analogue scale (VAS) score, Constant-Murley score, the University of California at Los Angeles (UCLA) score, and the American Shoulder and Elbow Surgeons (ASES) score were recorded before operation and at 1, 3, 6, and 12 months after operation. Results The operations were all successfully completed. The incisions healed by first intention and no related complications occurred. All patients were followed up 12-33 months (mean, 24.6 months). The VAS, Constant-Murley, UCLA, and ASES scores at different time points after operation were superior to those before operation (P<0.05). All of the above indicators further improved with time. Except for no significant difference in VAS and Constant-Murley scores between 6 and 12 months (P>0.05), the differences between the other time points were significant (P<0.05). At 12 months after operation, according to UCLA scoring standard, shoulder joint function was rated as excellent in 4 cases, good in 19 cases, and poor in 1 case, with an excellent and good rate of 96.0%. MRI showed that there was no graft re-tear and the transplanted tendon and bone tunnel healed. Conclusion The arthroscopic superior fulcrum reconstruction for IMRCT can effectively relieve the pain, improve the shoulder range of motion, and restore good shoulder function.

Methods We analyzed the clinical data of 11 patients with giant uterine cervical leiomyoma who were admitted in our hospital from October 2007 to March 2010. The incidence, diagnosis and surgical treatment of the disease were evaluated. Results Of the 11 cases, nine were retroperitoneal leiomyoma and two were submucous leiomyoma. There were nine misdiagnosed cases before operation, including five diagnosed as pelvic mass, one as uterine sarcoma and three as uterine corpus leiomyoma. Six patients underwent abdominal hysterectomy and bilateral salpingo-oophorectomy; two underwent abdominal hysterectomy; one underwent abdominal myomectomy; one underwent transvaginal myomectomy; and one underwent abdominal myomectomy with excision of cervical stump. Conclusion The giant uterine cervical leiomyoma is easily misdiagnosed preoperatively due to its special anatomic site. A good example is the retroperitoneal leiomyoma in which the pelvic anatomic structure is changed because of the extrusion of the tumor on other pelvic organs. Furthermore, injuries and bleeding often happen during the operation. Consequently, sufficient preoperative assessment and clearly identifying regional anatomical relations can effectively reduce the damage and bleeding during the operation.
ObjectiveTo summarize the data of robotic hysterectomy in patients with large and super-large uterus in single center, and explore the relevant clinical experience and advantages of robotic surgery.MethodsThe medical records of the patients with large uterus caused by gynecological diseases who underwent robotic hysterectomy in the Chinese PLA General Hospital from January 2016 to December 2018 were retrospectively analyzed. The patients with uterine size from 12 to 16 weeks of gestation were divided into large uterus group and those with uterine volume larger than 16 weeks of gestation were divided into super large uterus group.ResultsA total of 62 patients were included, including 28 in the large uterus group with the average uterus size of (14.3±2.1) gestational weeks, and 34 in the super large uterus group with the average uterus size of (19.9±2.8) gestational weeks. There was no significant difference in mean age, body mass index, history of abdominal surgery or diagnostic composition between the two groups (P>0.05), except for the size of the uterus (t=8.772, P<0.001). The operation time in the large uterus group was less than that in the super-large uterus group [(75.4±22.6) vs. (91.7±27.8) min; t=2.495, P=0.015]. The incidence of complications after robotic hysterectomy was 14.5% (9/62) in the 62 patients, including 14.3% (4/28) in the large uterus group and 14.7% (5/34) in the super-large uterus group. There was no significant difference in the amount of bleeding, blood transfusion rate, ratio of conversion to open surgery, average hospitalization days or incidence of postoperative complications between the two groups (P>0.05).ConclusionsRobotic hysterectomy has the advantages of flexible manipulator, 3-D operative field of vision and stability of manipulation. In addition, increased uterine volume does not lead to increased surgical trauma, nor apparently affect the prognosis.
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.
