Objective To study the safety and feasibility of modified laparoscopic Dixon surgery for rectal cancer. Methods In the procedure of modified laparoscopic Dixon surgery, the rectum with tumor was pulled out and cut and colon-rectum anastomosis was performed through anus. The clinical data of patients with rectal cancer between modified laparoscopic Dixon surgery (laparoscopy group) and open Dixon surgery (open group) were compared and analysed prospectively. The clinical data included operative time, volume of bleeding, number of lymph node dissection, volume of abdominal drainage, time to bowel gas passage, hospital stay and relative complications, such as anastomotic leakage, ureteral injury, dysuria and fecal incontinence. Results Fifty-eight cases were selected in this study between September 2007 and July 2008, including 25 laparoscopic surgery in laparoscopy group and 33 open surgery in open group. Patient’s data on gender, age, distance between tumor and anus edge, tumor diameter, tumor pathologic type and Dukes stage were similar between two groups by statistic analysis (Pgt;0.05). All the operations were performed successfully. Two cases experienced anastomotic leakage in laparoscopy group, while 1 case experienced anastomotic leakage in open group. All these patients got recovered by conservative treatment at last. No other complications were experienced, such as ureteral injury, dysuria, fecal incontinence, and so on. There were no significant differences in term of operative time, volume of bleeding and number of lymph node dissection between two groups (Pgt;0.05). The volume of abdominal drainage was less while the time to bowel gas passage and hospital stay were shorter in laparoscopy group than those in open group (P＜0.05). Conclusion This study reveals that it is safe and feasible to perform modified laparoscopic Dixon surgery for rectal cancer, and it presents the character of minimal invasion.
ObjectiveTo compare the effectiveness of coracoclavicular ligament reconstruction between by using autologous plantaris tendon graft combined with hook plate fixation and allogeneic tendon graft combined with hook plate fixation for treating acromiocavicular joint dislocation. MethodsThirty-three patients with acromioclavicular joint dislocation who accorded with the inclusion criteria between January 2013 and June 2014 were assigned into 2 groups. The patients were treated with autologous plantaris tendon graft combined with hook plate fixation in group A (n=17), and with allogeneic tendon graft combined with hook plate fixation in group B (n=16). Thirteen-one patients was followed up more than 12 months (15 in group A and 16 in group B). There was no significant difference in gender, age, cause of injury, sides, time between injury and surgery, and type of dislocation (P>0.05). The assessments included operation time, hospitalization time, hospitalization expenses, shoulder range of motion, gap of acromioclavicular, Constant-Murley scores, and visual analogue scale (VAS) for pain. ResultsThe operation time of group A was significantly longer than that of group B, and the hospitalization expense was significantly lower than that of group B (P<0.05). There was no significant difference in hospitalization time (t=1.046, P=0.316). The incisions healed by first intention, and hook plate was removed after 3 months. The mean follow-up time was 21.3 months (range, 19-34 months) in group A and was 23.7 months (range, 18-37 months) in group B. X-ray examination showed no osteolysis. There was no significant difference in gap of acromiocavicular between 2 groups at preoperation, 1 week after operation, and last follow-up (P>0.05). No redislocation of acromioclavicular joint and rejection reaction occurred during follow-up. At last follow-up, there was no significant difference in shoulder range of motion, Constant-Murley score, and VAS score between 2 groups (P>0.05). ConclusionCoracoclavicular ligament reconstruction by autologous plantaris tendon or allogeneic tendon graft combined with hook plate fixation for the treatment of acromioclavicular joint dislocation can achieve good effectiveness. The appropriate treatment should be chosen according to the patient's economic situation.
Objective To explore effectiveness of arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique in the treatment of recurrent anterior dislocation of shoulder joint. Methods A clinical data of 14 patients with recurrent anterior dislocation of shoulder joint and glenoid bone defect, who were met the selective criteria and admitted between February 2021 and February 2022, was retrospectively analyzed. All patients were treated with arthroscopic Eden-Hybinette procedure and the bone blocks were fixed by using Triple-Pulley and four point anti-rotation fixation technique. There were 9 males and 5 females with an average age of 31.2 years (range, 22-40 years). Shoulder dislocation occurred 4-10 times (mean, 6.8 times). The time from the initial dislocation to the admission was 1-6 years (mean, 3.3 years). The Instability Severity Index Score (ISIS) was 7.2±0.8, the Beighton score was 2.9±2.4, and the width ratio of glenoid bone defect was 26.64%±1.86%. Pre- and post-operative visual analogue scale (VAS) score, the University of Califonia-Los Angeles (UCLA) shoulder score, Constant score, and American Association of Shoulder and Elbow Surgeons (ASES) score were used to evaluate shoulder pain and function. The position, healing, resorption, and remodeling (glenoid area) of the bone blocks were evaluated by CT of shoulder joint. ResultsAll patients underwent surgery successfully without any serious complications. All patients were followed up 11.5-13.8 months (mean, 12.0 months). The VAS scores of shoulder joint after operation decreased compared to preoperative levels, while the UCLA score, Constant score, and ASES score all increased, with significant differences (P<0.05). And with the prolongation of time, the above indicators further improved, and the differences between different time points were significant (P<0.05). Imaging reexamination showed that the bone block completely filled the glenoid defect, with good position and no significant displacement. Over time, the bone block healed and partially absorbed and remodelled. The postoperative glenoid area increased significantly compared to preoperative area (P<0.05). With the prolongation of time, the glenoid area significantly decreased, but the difference was not significant between different time points (P>0.05). Conclusion For the recurrent anterior dislocation of shoulder joint, Triple-Pulley and four point anti-rotation fixation technique in Eden-Hybinette procedure can effectively prevent bone rotation, make fixation more reliable, and easy to operate and achieve good effectiveness.
ObjectiveTo observe effectivness and safeness of self-made dentation hook plate associated with hot-air balloon technique in treating Mutch Ⅰ or Ⅱ type isolated greater tuberosity fractures of humerus.MethodsBetween January 2016 and December 2018, 15 patients with Mutch Ⅰ or Ⅱ type greater tuberosity fractures were treated with self-made dentation hook plate associated with hot-air balloon technique. There were 9 males and 6 females with an average age of 45.1 years (range, 29-62 years). The injury causes included falling injury in 9 patients and traffic accident injury in 6 patients. According to Mutch classification, 4 cases were MutchⅠ type and 11 cases were Mutch Ⅱ type. There were 7 cases with anterior dislocation of shoulder. The time from injury to operation was 2-10 days (mean, 4.5 days).ResultsAll 15 patients were followed up 8-16 months, with an average of 13.5 months. There was no infection of incision, loss of reduction of fracture block, delayed union or nonunion. The average time of fracture union was 6.5 months (range, 4-8 months). One patient had axillary paralysis at 1 day after operation, and was treated with nutritional nerve therapy, the symptoms disappeared after 2.5 months. Three patients had slight subacromial impingement. After fracture healing, the hook plate was taken out in advance, and the pain and abnormal noise disappeared during shoulder abduction. At last follow-up, Costant-Murley score used to evaluate shoulder joint function was 88-100, with an average of 96.8; 8 cases were excellent, 7 cases were good, and the excellent and good rate was 100%. The internal fixator was removed after 8-16 months after the secondary operation with no re-fracture occurred.ConclusionThe self-made dentation hook plate associated with hot-air balloon technique is a safe and reliable method for the treatment of Mutch Ⅰ or Ⅱ type isolated greater tuberosity fracture of humerus.
ObjectiveTo investigate the clinical, laboratory and imaging evaluation, treatment and prognosis of patients with idiopathic hypertrophic pachymeningitis (IHP) with ophthalmic manifestations as the first symptom.MethodsA retrospective case analysis. Eight patients displaying symptoms of IHP were recruited from the Neuro-ophthalmology Department in the First Medical Center of Chinese PLA General Hospital from January 2016 to April 2019 were inculed in this study. There were 6 males and 2 females, aged from 11 to 65 years, with an average age of 48.00±19.08 years. The course of disease ranged from 30 days to 7.5 years, with an average course of 17.00±30.08 months. The age, symptoms and signs of all patients were recorded. All patients underwent ophthalmic examination, orbit or brain MRI or CT examinations, blood routine examination, biochemistry, tumor markers, immunity, hepatitis B, syphilis, HIV, thyroid function and other laboratory tests, and lumbar puncture was performed to measure the cerebrospinal fluid (CSF) pressure and indicators. The clinical manifestations, orbital or brain MRI imaging and laboratory examination characteristics were summarized. Treatment and prognosis were also observed.ResultsIn total of 8 patients, visual loss was presented in 6 patients, visual loss and diplopia were presented in 1 patient, and diplopia was presented in 1 patient. Binocular involvement in 7 patients and monocular involvement in 1 patient. Other symptoms including headache and hear loss and so on. Optic disc edema in 1 eye and optic disc pallor in 6 eyes were reviewed by fundus examination. The laboratory examination showed that the angiotensin converting enzyme abnormal in 4 patients, the anti-thyroid peroxidase antibody abnormal in 3 patients and immunoantibodies positive in 3 patients. CSF measurements showed that the protein level elevated in all patients. Orbit and/or brain MRI and CT examination showed that optic nerve involvement in 6 patients, oculomotor nerve involvement in 1 patient, and cavernous sinus region involvement in 2 patients. Glucocorticoid was effective in all patients, and the visual acuity significantly improved in 4 patients, the diplopia was completely resolved in 2 patients, and the disease modifying therapy (DMT) was combined to prevent recurrence in 7 patients. No recurrence was observed in an average follow-up time of 26.63±16.55 months.ConclusionsIHP patients may be first visit an ophthalmologist due to vision loss in bilateral eyes simultaneous or sequentially. IHP patients are often associated with headache and other cranial nerve paralysis symptoms. Definitive diagnosis of IHP depends on imaging examination. Glucocorticoid treatment is effective in early phase, but it is tendency to progress and relapse, suggesting combined with DMT as early as possible.
ObjectiveTo investigate effectiveness of arthroscopic superior capsular reconstruction using a “sandwich” patch combined with platelet-rich plasma (PRP) injection in treating massive irreparable rotator cuff tears. Methods A clinical data of 15 patients (15 sides) with massive irreparable rotator cuff tears, who were admitted between September 2020 and March 2023 and met selective criteria, was retrospectively analyzed. There were 8 males and 7 females with an average age of 62.1 years (range, 40-80 years). The rotator cuff tears were caused by trauma in 7 cases and other reasons in 8 cases. The disease duration ranged from 5 to 25 months, with an average of 17.7 months. According to the Hamada grading, the rotator cuff tears were rated as grade 1 in 2 cases, grade 2 in 8 cases, and grade 3 in 5 cases. All patients were underwent superior capsular reconstruction using the “sandwich” patches (autologous fascia lata+polypropylene patch+autologous fascia lata) combined with PRP injection on patches. The pre- and post-operative active range of motion (ROM) of the shoulder joint, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, University of California, Los Angeles Shoulder Rating Scale (UCLA) score, and visual analogue scale (VAS) score were recorded. The subacromial space was measured on the imaging and rotator cuff integrity was assessed based on Sugaya grading. Results All incisions healed by first intention after operation without any complications such as infection. All patients were followed up 12-18 months (mean, 14.4 months). At last follow-up, the active ROMs of flexion, abduction, external rotation, internal rotation of the shoulder joint, subacromial space, ASES score, Constant-Murley score, and UCLA score increased, and VAS score decreased, showing significant differences when compared with preoperative values (P<0.05). There was no significant difference in the Sugaya grading between last follow-up and immediately after operation (P>0.05). Conclusion For massive irreparable rotator cuff tears, arthroscopic superior capsular reconstruction using the “sandwich” patches combined with PRP injection can restore stability of the shoulder joint, promote rotator cuff healing, and achieve good short-term effectiveness.
