Objective To explore complications of endoscopic thyroidectomy and conventional thyroidectomy and to analyze causes of them in order to reducing complications of endoscopic thyroidectomy. Methods A total of 1 112 patients with thyroid diseases from September 2008 to March 2017 in the Shanghai Tongren Hospital were collected, then were designed to endoscopic thyroidectomy group and conventional thyroidectomy group. The recurrent laryngeal nerve injury, hypoparathyroidism, postoperative bleeding, tracheoesophageal injury, poor healing of surgical wound, skin ecchymosis and subcutaneous effusion, neck discomfort, and CO2 related complications were observed. Results ① There were 582 cases in the endoscopic thyroidectomy group and 530 cases in the conventional thyroidectomy group, the baselines such as the gender, age, most diameter of tumor, diseases type, operative mode, operative time, and intraoperative bleeding had no significant differences between the endoscopic thyroidectomy group and the conventional thyroidectomy group (P>0.05). ② All the operations were performed successfully, none of patients was converted to the open operation. The rates of the recurrent laryngeal nerve injury, hypoparathyroidism, postoperative bleeding, and tracheoesophageal injury had no significant differences in these two groups (P>0.05). The rates of the poor healing of surgical wound and neck discomfort were significantly lower and the rate of the skin ecchymosis and subcutaneous effusion was significantly higher in the endoscopic thyroidectomy group as compared with the conventional thyroidectomy group (P<0.05). There were 32 cases of CO2 related complications in the endoscopic thyroidectomy group. Conclusion Results of this study show that endoscopic thyroidectomy is safe for thyroid diseases, it’s complications could be reduced by improving operation technique.
ObjectiveTo discuss clinical significance of total endoscopic thyroidectomy (TET) via chest-breast approach. MethodsThe clinical data of 890 patients with thyroid diseases from September 2008 to September 2015 in this hospital were analyzed retrospectively. These patients were divided into TET group (received TET, n=420) and traditional group (received traditional thyroidectomy, n=470). The data of operation and postoperative recovery were compared between these two groups. ResultsThere was no significant difference between the TET group and the traditional group in the operation time [(73.571 4±28.533 9) min versus (70.212 8±27.199 8) min, t=1.80, P=0.072 7], bleeding volume [(30.714 3±14.225 1) mL versus (29.106 4±13.559 1) mL, t=1.73, P=0.084 8], postoperative drainage [(60.000 0±27.287 9) mL versus (56.595 7±27.803 5) mL, t=1.84, P=0.066 2], postoperative hospitalization time [(5.333 3±1.085 1) d versus (5.446 8± 1.089 0) d, t=1.55, P=0.120 4], postoperative 24 h pain score [(5.333 3±2.308 7) points versus (5.404 3±2.182 1) points, t=0.47, P=0.637 8] and postoperative injury rate of recurrent laryngeal nerve [0.714 2% (3/420) versus 0.851 1% (4/470), x2=0.053 2, P=0.817 6] and hypoparathyroidism rate [0.476 2% (2/420) versus 0.851 1% (4/470), x2=0.465 5, P=0.495 1]. The score of aesthetic effect of incision on day 7 after operation in the TET group was significantly higher than that in the traditional group [(7.809 5±1.296 9) points versus (3.361 7±1.391 8) points, t=49.14, P < 0.000 1]. ConclusionTET is safe and effective, and could improve cosmetic effect for patients with thyroid diseases.
ObjectiveTo summarize the current common clinical laparoscopic gastrointestinal tumor surgical localization methods, and to provide reference for clinicians to choose reasonable localization methods. MethodThe domestic and foreign literatures related to laparoscopic gastrointestinal tumor surgical localization methods were searched and reviewed. ResultsThe common localization methods for laparoscopic gastrointestinal tumor surgery were imaging localization, preoperative endoscopic localization, intraoperative endoscopic localization and intraoperative fluorescence localization, among which abdominal enhanced CT and endoscopic-related localization methods were the most commonly used localization methods in clinical practice at present. ConclusionA variety of methods are available for surgeons to choose from, and the precise localization of tumors is better facilitated by combining multiple methods.
ObjectiveTo systematically evaluate the reliability and stability of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and conventional open thyroidectomy (COT) in the treatment of differentiated thyroid cancer.MethodsThe clinical studies of TOETVA and COT in the treatment of differentiated thyroid cancer were retrieved from major databases including PubMed, Embase, Cochrane Library, Wanfang, and CNKI by computer. The search date ended on March 1, 2020. Two investigators screened the literatures strictly and extracted the data following the pre-defined inclusion and exclusion criteria, and then used RevMan 5.3 software for meta-analysis.ResultsA total of 7 studies including 1 465 patients were included in this meta-analysis. The results showed: compared with the COT group, the operation time of the TOETVA group was longer [WMD=35.18, P=0.000 1], and the number of lymph node dissections in the central area was larger [WMD=1.42, P=0.000 5]. But the intraoperative blood loss [WMD=–5.32, P=0.39], the length of hospital stay after operation [WMD=0.05, P=0.94], the incidences of transient recurrent laryngeal nerve palsy [OR=0.81, P=0.43], transient hypocalcemia [OR=0.55, P=0.35], permanent hypocalcemia [OR=0.39, P=0.22], permanent recurrent laryngeal nerve palsy [OR=1.34, P=0.73], and hematoma [OR=1.29, P=0.69] were not statistically significant between the two groups.ConclusionsTOETVA has a higher stability. Although the COT has a shorter operation time, the former has a higher central lymph node dissection rate, and there is no scar on the neck after surgery and no significant difference in the incidence of postoperative complications.
Esophageal diseases include esophageal malignant diseases and benign diseases, with a high incidence in our country. Along with the development of the endoscopic technique, many of them which required medical treatment or surgery in the past can now be cured by endoscopic surgery. This article is an overview of long-term follow-up of endoscopic surgery for the common esophageal disease, such as early squamous cell carcinoma, esophageal stricture, achalasia and submucosal tumor of the esophagus.
ObjectiveTo summarize the various treatment methods for reducing jaundice in the elderly patients with malignant obstructive jaundice (MOJ), and provide reference for the treatment of elderly MOJ.MethodUsing “malignant obstructive jaundice” as the Chinese keyword and the English keyword, a computer search of the literatures on the treatment of elderly MOJ patients was conducted and reviewed.ResultsThe treatment methods of reducing jaundice in elderly MOJ included radical surgery, cholangiojejunostomy, endoscopic ultrasound-guided biliary drainage, endoscopic biliary stent implantation, percutaneous transhepatic biliary drainage and stent implantation. Radical surgery was the most effective, but it was traumatic and had many complications for elderly patients. Cholangiojejunostomy was effective and suitable for elderly patients who cannot tolerate major surgery. Endoscopic ultrasound-guided biliary drainage was less traumatic to elderly patients, but technical difficulty. Endoscopic biliary stent implantation was currently the first-line choice for the treatment of elderly patients with advanced MOJ. Percutaneous transhepatic biliary drainage and stent implantation were suitable for elderly and frail patients with high obstruction.ConclusionThe treatment of elderly MOJ needs to be individualized and regionalized, and appropriate treatment methods should be selected according to the patient’s condition and the medical level of the medical center.
ObjectiveTo systematically review the efficacy and safety of percutaneous endoscopic lumbar discectomy (PELD) for L5/S1 disc herniation via transforaminal approach (TF-PELD) versus interlaminar approach (IL-PELD).MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) and the cohort studies of TF-PELD versus IL-PELD for L5/S1 disc herniation from inception to October 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 1 RCT and 7 cohort studies involving 414 patients were included. The results of meta-analysis indicated that: compared with IL-PELD group, TF-PELD group had longer operative time (MD=17.42, 95%CI 12.86 to 21.97, P<0.000 01) and more frequency of intraoperative fluoroscopy (MD=8.42, 95%CI 6.18 to 10.65,P<0.000 01), respectively. However, there were no significant differences between two groups in the post-operative visual analogue scale (MD=0.01, 95%CI –0.23 to 0.25,P=0.94), the post-operative Oswestry disability index (MD=–0.46, 95%CI –2.42 to 1.49, P=0.64), the excellent and good outcomes rate (RR=1.00, 95%CI 0.89 to 1.12, P=0.96), and the rate of complications (RR=0.73, 95%CI 0.45 to 1.18, P=0.20).ConclusionCurrent evidence shows that TF-PELD and IL-PELD are equally effective and safe for L5/S1 disc herniation, but IL-PELD is superior to TF-PELD in less operative time and less radiation exposure. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
ObjectiveTo investigate the feasibil ity and short-term effectiveness of percutaneous endoscopic spine surgery for treatment of lumbar disc herniation with posterior ring apophysis separation. MethodsBetween July 2008 and January 2013, 57 patients with lumbar disc herniation and posterior ring apophysis separation were treated. There were 39 males and 18 females, aged from 13 to 46 years (mean, 26.7 years). Of 57 cases, 29 had a clear trauma history. All patients had single segmental unilateral lumbar disc herniation, and the location was at L4, 5 in 22 cases and at L5, S1 in 35 cases; there were 25 cases of lateral bone fragments and 32 cases of central cortical and cancellous fragments. While fracture located at posterior inferior edge of the vertebrae at L4 level in 9 cases and at L5 level in 8 cases, at posterior superior edge at L5 level in 13 cases and in S1 level in 27 cases. Percutaneous endoscopic surgeries were performed via interlaminar or transforaminal approach from unilaterally symptomatic side for discectomy of lumbar disc herniation and partial or complete resection of free bone fragments. ResultsAccurate positioning was obtained in all patients during operation, and no complication of nerve root injury, hematoma formation, or dural tear occurred. The operation time was 20-85 minutes; the intraoperative fluoroscopy times were 2-15 times, and the blood loss was 3-10 mL. Postoperative radiographic examination showed that bone fragment was not removed in 16 cases, was partly removed in 32 cases, and was completely removed in 9 cases. Disc was completely removed. All patients were followed up 10-64 months (median, 16 months). According to modified Macnab criteria for the evaluation of effectiveness, the results were excellent in 48 cases, good in 6 cases, and fair in 3 cases, and the excellent and good rate was 94.7%. ConclusionPercutaneous endoscopic spine surgery through unilaterally symptomatic approach has advantages of small tissue damage and lumbar structure damage, less bleeding, and shorter recovery time. It has a good short-term effectiveness, but long-term effectiveness need further follow-up.
ObjectiveTo identify effect of quantitative indicators of ilium height on approach of percutaneous endoscopic lumbar discectomy (PELD) treatment in patients with L5, S1 lumbar disc herniation.MethodsA retrospective study between May 2014 and March 2016 was conducted, including 100 patients with disc herniation at L5, S1, who were initially enrolled for the PELD treatment. Among them, 66 patients were successfully treated with PELD (group A), and the other 34 patients failed to perform puncture, catheterization, or microscopical operation due to the influence of iliac bone and other peripheral bone structures and treated with alternative surgical plans. By analyzing the X-ray films of lumbar vertebrae (including bilateral ilium) of the two groups before operation, the concept of ilium height rate and ilium angle rate was put forward innovatively. The ilium height rate and ilium angle rate of the two groups were measured and compared, and the diagnostic critical points of ilium height rate and ilium angle rate were determined by ROC curve analysis.ResultsThe ilium height rate was 0.61±0.09, 0.74±0.05 and the ilium angle rate was 0.66±0.08, 0.80±0.08 in groups A and B, respectively, showing significant differences between the two groups (F=69.729, P=0.000; F=65.165, P=0.000). ROC curve analysis showed that the critical point of ilium height rate was 0.71 (area under ROC curve was 0.927, P=0.000), and the critical point of ilium angle rate was 0.75 (area under ROC curve was 0.965, P=0.000).ConclusionPELD is not recommended for patients with L5, S1 intervertebral disc herniation, when the ilium height rate is greater than 0.71 and/or the ilium angle rate is greater than 0.75. Other surgical plans such as transpedicular approach, transpedicular approach, or open surgery, should be recommended to reduce the risk of surgery and the pain of patients.
