Objective To explore the clinical result and complications of noncyclic-PPH surgery in treating internal hemorrhoids.Methods In this study,we evaluate the clinical outcome,such as clinical efficacy,operation time,length of hospital stay,postoperative pain degree and incidence of complications in 120 hemorrhoid patients,randomly divided into control group (60 cases) and observation group (60 cases)based on digital table method,receiving respectively noncyclic-PPH,or PPH (procedure for prolapse and hemorrhoids).Results Two groups were similar in average operation time and average length of hospital stay (P ＞ 0.05).The postoperative VAS score at each time point,was significantly lower in noncyclic-PPH group than the control group (P ＜ 0.05).Non-cyclic PPH group were also significantly lower in postoperative complications than the control group (P ＜ 0.05).Conclusion Compared with PPH surgery,patients with noncyclic-PPH have fewer pain complications or trauma.

Objective:To investigate the clinical value of short segment fusion and long segment fusion combined with posterior pedicle screw system internal fixation in the treatment of degenerative scoliosis.Methods:74 patients with degenerative scoliosis who were treated in the Affiliated Hospital of Southwest Medical University from January 2014 to February 2018 were enrolled in the study. The patients were divided into group A and group B with a random number table of 37 cases each. Group A was treated with short segment fusion and posterior pedicle screw system internal fixation, while group B was with long segment fusion and posterior pedicle screw system internal fixation. The Cobb angle of scoliosis, the balance of coronal and sagittal plane of spine were observed before operation, 1 week after operation, 3 months after operation and 6 months after operation, and the incidence of early and long-term complications were counted.Results:The Cobb angle of scoliosis in group B was lower than that of group A at 1 week, 3 months and 6 months after operation ( P<0.05). There was no significant difference in the balance of coronal plane and sagittal plane between the two groups at 1 week and 3 months after operation ( P>0.05). There was significant difference in the balance of coronal plane and sagittal plane between the two groups at 6 months after operation ( P<0.05). There was no significant difference in the incidence of early postoperative complications between the two groups ( P>0.05). Conclusions:Long segment fusion and posterior pedicle screw system internal fixation can improve the Cobb angle and reduce the incidence of postoperative scoliosis, but it is easy to appear the imbalance of coronal and sagittal planes, which can be selected according to the actual situation.

BACKGROUND:As a routine method after lumbar spine surgery,a drainage tube is convenient for postoperative bleeding drainage and management,and there is still no consensus on the choice of postoperative removal time for short-segment lumbar spine surgery with less risk. OBJECTIVE:To explore the effect of different drainage times on early clinical efficacy after short-segment lumbar fusion. METHODS:A prospective randomized controlled study was performed on 220 patients in the Affiliated Hospital of Southwest Medical University who underwent posterior lumbar interbody fusion for lumbar degenerative diseases from March 2017 to April 2021.According to the different drainage times,the patients were randomly divided into removal on the second day after operation(group A),removal on the third day after operation(group B),and removal after the observation method 24-hour drainage volume<30 mL(group C).The perioperative indicators and follow-up results of the three groups of patients were observed and compared. RESULTS AND CONCLUSION:(1)Because 7 patients were lost to follow-up,2 patients were excluded,and 211 patients were finally included(72 patients in group A,71 patients in group B,and 68 patients in group C).(2)The average drainage time of group C was 2.91 days.The postoperative drainage volume in group A was significantly less than that in groups B and C,and the difference was statistically significant(P<0.05).On day 3 after operation,the hematocrit value of group C was lower than that of group A and group B,and the difference was statistically significant(P<0.05).Postoperative activity time and hospital stay in group A were shorter than those in groups B and C,and the difference was statistically significant(P<0.05).(3)Four patients in group A,two patients in group B and three patients in group C received an allogeneic blood transfusion.There was no significant difference among the groups(P>0.05).(4)In terms of postoperative complications,there were no statistical differences in postoperative wound leakage and surgical site infection in all three groups(P>0.05).(5)All patients were followed up for more than 12 months.Visual analog scale score and Oswestry dysfunction index of the three groups of patients before discharge and at the last follow-up were significantly improved compared with those before surgery(P<0.05).There was no statistical significance among the groups(P>0.05).(6)It is indicated that the removal of the drainage tube on the second day after a posterior lumbar fusion can effectively reduce the time to get out of bed and hospital stay,without increasing the postoperative blood loss and the risk of complications.

BACKGROUND:Some patients with cervical spondylosis have not been fully corrected sagittal position balance after cervical surgery,and this continuous sagittal position imbalance may be an important reason for the poor long-term clinical outcome of patients. OBJECTIVE:To analyze the correlation between the cervical sagittal position balance parameters and their changes and the clinical efficacy of patients in the unbalanced state after anterior cervical decompression and fusion and to explore the necessity of surgical correction of sagittal balance in order to improve the clinical effect in the later stage. METHODS:A retrospective analysis was performed on 125 patients with cervical spondylosis who underwent anterior cervical decompression and fusion in the Department of Spinal Surgery of Affiliated Hospital of Southwest Medical University from July 2019 to July 2022.Follow-up patients had good postoperative recovery(neck disability index score less than 10%one week after surgery)and had complete follow-up data.According to the axial vertical distance(C2-7 SVA)in sagittal position one week after surgery,patients were divided into type I imbalance group(C2-7 SVA loss≤5 mm,n=27),type Ⅱ imbalance group(C2-7 SVA loss>5 mm,and≤10 mm,n=19),and type Ⅲ imbalance group(C2-7 SVA loss>10 mm,n=12),and non-unbalanced group(C2-7 SVA in the normal range,n=67).The changes of visual analog scale score and neck disability index were compared among groups postoperatively and the last follow-up,as well as the changes of imaging sagittal balance parameters C2-7 cobb angle,C2-7 SVA value,neck inclination angle,T1 inclination angle,and thoracic entrance angle.The correlation between the late clinical effect and postoperative cervical sagittal disequilibrium was explored. RESULTS AND CONCLUSION:(1)There was no statistical difference in general data among the four groups(P>0.05).All patients underwent successful surgery without serious complications and postoperative wound infection.The follow-up time was more than 1 year.(2)There was no significant difference in preoperative symptom score and clinical efficacy one week after surgery(P>0.05).At the last follow-up,pain visual analog scale score,neck disability index and C2-7 SVA were lower than those before surgery but higher than those one week after surgery(P<0.05).C2-7 cobb angle was increased compared with those before operation(P<0.05).T1 inclination angle was decreased compared with those before operation(P<0.05).(3)Pearson correlation test showed that the change of neck disability index was positively correlated with the change of C2-7 SVA(P<0.05).(4)It is indicated that anterior cervical decompression and fusion is effective in the treatment of cervical spondylosis,and can effectively relieve the symptoms of patients.Patients with more severe cervical sagittal disequilibrium after surgery had worse curative effect in the later period.Continuous sagittal disequilibrium in patients with cervical spondylosis after surgery is an important cause of poor curative effect in the later stage.Clinicians should pay more attention to the correction of cervical sagittal balance before and during surgery,formulate surgical strategies and plans according to sagittal balance parameters before surgery,and correct C2-7 SVA intraoperatively to the normal range.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.
