Electroencephalogram (EEG) has been an important tool for scientists to study epilepsy and evaluate the treatment of epilepsy for half a century, since epilepsy seizures are caused by the diffusion of excessive discharge of brain neurons. This paper reviews the clinical application of scalp EEG in the treatment of intractable epilepsy with vagus nerve stimulation (VNS) in the past 30 years. It mainly introduces the prediction of the therapeutic effect of VNS on intractable epilepsy based on EEG characteristics and the effect of VNS on EEG of patients with intractable epilepsy, and expounds some therapeutic mechanisms of VNS. For predicting the efficacy of VNS based on EEG characteristics, EEG characteristics such as epileptiform discharge, polarity of slow cortical potential changes, changes of EEG symmetry level and changes of EEG power spectrum are described. In view of the influence of VNS treatment on patients’ EEG characteristics, the change of epileptiform discharge, power spectrum, synchrony, brain network and amplitude of event-related potential P300 are described. Although no representative EEG markers have been identified for clinical promotion, this review paves the way for prospective studies of larger patient populations in the future to better apply EEG to the clinical treatment of VNS, and provides ideas for predicting VNS efficacy, assessing VNS efficacy, and understanding VNS treatment mechanisms, with broad medical and scientific implications.
Objective To evaluate the safety and mid- to long-term efficacy of surgical correction of isolated partial anomalous pulmonary venous connection (IPAPVC). Methods We retrospectively collected consecutive patients who were diagnosed with IPAPVC and underwent surgical correction at Fuwai Hospital of Chinese Academy of Medical Sciences and Fuwai Yunnan Cardiovascular Hospital from June 2009 to May 2019, summarized the basic preoperative and intraoperative data of patients, analyzed the postoperative and mid- to long-term follow-up results. Results A total of 54 patients were enrolled, including 29 males and 25 females, with an average age of 16.20±2.40 years, ranging from 1 month to 62 years. There were 28 (51.9%) patients with varying degrees of arrhythmia, 22 (40.7%) patients with cardiac insufficiency, and 39 (72.2%) patients with pulmonary hypertension. According to Bordy's typing, 14 (25.9%) patients were classified as type A, 23 (42.6%) type B, 4 (7.4%) type C, 5 (9.3%) type D and 8 (14.8%) mixed type. Transthoracic echocardiography was performed in the whole group of patients and the accuracy of staging diagnosis was 66.7% (36/54), and cardiac CT angiography (CTA) was performed in 37 patients and the accuracy of staging diagnosis was 94.6% (35/37). All surgical procedures were assisted with cardiopulmonary bypass, aortic cross-clamping time was 0-219 (67.02±5.23) min, cardiopulmonary bypass time was 40-261 (105.09±5.23) min, and there was no serious intraoperative complication. Postoperative tracheal intubation time was 0-230 (13.33±4.20) h, intensive care unit stay was 0-13 (1.89±0.28) days, postoperative hospital stay was 5-18 (7.20±0.38) days, and follow-up time was 16-140 (62.58±5.12) months. There were 2 (3.7%) all-cause postoperative deaths, including 1 in-hospital death and 1 death during the follow-up, and there was no intraoperative death. Among the survivors, there were 3 patients with surgery-related complications: 1 patient had atrial septal defect with the second surgical treatment, 1 early obstruction of the superior vena cava and 1 arrhythmia. Two patients had complications of IPAPVC (atrial fibrillation, collateral circulation) prior to surgery and underwent the second surgery with a poor prognosis, and 1 patient had preoperative cardiac insufficiency and atrial fibrillation, whose symptoms persisted for a long time during the follow-up. Conclusion IPAPVC accounts for a lower percentage of partial anomalous pulmonary venous connection, transthoracic echocardiography combined with CTA improves diagnostic accuracy, and IPAPVC should be treated with elective surgery after diagnosis. The surgical approach should be individualized with imaging features such as disease staging, number of drains and drainage location. Surgical treatment of IPAPVC is safe and effective, and regular follow-up is warranted.
ObjectiveTo systematically evaluate the efficacy and safety of jejunostomy tube versus nasojejunal tube for enteral nutrition after radical resection of esophageal cancer. MethodsPubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM databases were searched to collect the clinical effects of jejunostomy tube versus nasojejunal nutrition tube after radical resection of esophageal cancer from inception to October 2021. Meta-analysis was performed using RevMan 5.4 software. ResultsTwenty-six articles were included, including 17 randomized controlled studies and 9 cohort studies, with a total of 35 808 patients. Meta-analysis results showed that: in the jejunostomy tube group, the postoperative exhaust time (MD=–4.27, 95%CI –5.87 to –2.66, P=0.001), the incidence of pulmonary infection (OR=1.39, 95%CI 1.06 to 1.82, P=0.02), incidence of tube removal (OR=0.11, 95%CI 0.04 to 0.30, P=0.001), incidence of tube blockage (OR=0.47, 95%CI 0.23 to 0.97, P=0.04), incidence of nasopharyngeal discomfort (OR=0.04, 95%CI 0.01 to 0.13, P=0.001), the incidence of nasopharyngeal mucosal damage (OR=0.13, 95%CI 0.04 to 0.42, P=0.008), the incidence of nausea and vomiting (OR=0.20, 95%CI 0.08 to 0.47, P=0.003) were significantly shorter or lower than those of the nasojejunal tube group. The postoperative serum albumin level (MD=5.75, 95%CI 5.34 to 6.16, P=0.001) was significantly better than that of the nasojejunal tube group. However, the intraoperative operation time of the jejunostomy tube group (MD=13.65, 95%CI 2.32 to 24.98, P=0.02) and the indent time of the postoperative nutrition tube (MD=17.81, 95%CI 12.71 to 22.91, P=0.001) were longer than those of the nasojejunal nutrition tube. At the same time, the incidence of postoperative intestinal obstruction (OR=6.08, 95%CI 2.55 to 14.50, P=0.001) was significantly higher than that of the nasojejunal tube group. There were no statistical differences in the length of postoperative hospital stay or the occurrence of anastomotic fistula between the two groups (P>0.05). ConclusionIn the process of enteral nutrition after radical resection of esophageal cancer, jejunostomy tube has better clinical treatment effect and is more comfortable during catheterization, but the incidence of intestinal obstruction is higher than that of traditional nasojejunal tube.
Objective To compare the clinical efficacy and safety of suturesuspension single hole laparoscopic cholecystectomy and traditional laparoscopic cholecystectomy (LC) in the treatment of gallbladder disease. Methods A total of 86 cases who got treatment in our hospital from February 2014 to July 2015 were collected prospectively, and then 86 cases were divided into 2 groups: 43 cases of control group underwent LC and 43 cases of experimental group underwent suturesuspension single hole laparoscopic cholecystectomy. Clinical efficacy and safety of the two groups were compared. Results ① Complication. No one suffered from bile duct injury, bile leakage, bile duct stricture, and umbilical hernia; but there were 2 cases suffered from complications in control group, including 1 case of abdominal pain and 1 case of bloating, and the morbidity was 4.65% (2/43). The morbidity of experimental group was 0, there was no significant difference between the 2 groups in the morbidity (P>0.05). During the follow-up period, 1 case suffered from long-term compilation in experimental group, and 2 cases in normal group, there was no significant difference in the long-term complication between the 2 groups (P>0.05). ② Operation and hospitalization. The blood loss and operation time in the experimental group were lower than those of the control group (P<0.05), but there was no significant difference in the hospital stay and hospitalization cost between the 2 groups (P>0.05). ③ Postoperative electrolytes, liver and kidney function. The levels of Na+ and K+ in the experimental group were higher than those of the control group (P<0.05), and the levels of alanine aminotransferase and aspartate aminotransferase were lower than those of control group (P<0.01), but there was no significant difference in the blood urea nitrogen and serum creatinine between the 2 groups (P>0.05). ④ The recovery of gastrointestinal function after surgery. The anal exhaust time and bowel sounds recovery time in experimental group were shorter than those of the control group (P<0.01). Conclusion Suturesus-pension single hole laparoscopic cholecystectomy in the treatment of gallbladder disease is safe, effective, and minimally invasive, and it has little disturbance on gastrointestinal function and liver function, which is worthy of clinical application.
ObjectiveTo investigate the long-term efficacy of intersphincter approach combined with virtual solid and hanging line in the treatment of posterior high complex anal fistulas and risk factors for recurrence. Methods A total of 167 patients with posterior high complex anal fistula treated in our hospital from April 2020 to June 2023 were retrospectively included. According to different treatment methods, the patients were divided into observation group (n=88) and control group (n=79). The observation group was treated with the combination of virtual solid and hanging line via intersphincter approach, while the control group was treated with cutting and wire hanging drainage. The general clinical data, the height of the internal fistula opening and the anorectal pressure before and after 1, 2 and 3 months were compared between the two groups. The patients were divided into recurrence group (n=50) and non-recurrence group (n=117) according to the recurrence situation during the follow-up period. Univariate and multivariate logistic regression were used to analyze the risk factors of postoperative anal fistula recurrence, and Kaplan-Meier method was ued to draw relapse-free curve. ResultsCompared with the control group, the observation group had longer operative time, shorter wound healing time and shorter hospital stay (P<0.05). At 1, 2 and 3 months after operation, the anal resting pressure and maximum anal retraction pressure in the observation group were significantly increased, while the height of the inner mouth was significantly decreased, with statistical significance (P<0.05). There were statistically significant differences in age, body mass index, gender, regular dressing change to hospital after discharge, history of anal fistula surgery, clarity of internal opening and treatment methods between the recurrence group and the non-recurrence group (P<0.05). The results of multivariate logistic regression analysis showed that the independent risk factors for postoperative recurrence of patients with posterior high complicated anal fistula were that they didn’t regularly go to the hospital for dressing change after discharge, had a history of anal fistula operation, had unclear internal orifice and underwent thread-drawing drainage (P<0.05). The cumulative relapse-free rate of patients in the observation group and the control group was 84.58% and 67.73% respectively, and the difference was statistically significant (P<0.05). ConclusionsThe treatment of posterior high complex anal fistulas by intersphincter approach combined with virtual solid and hanging line has a good effect in protecting anal function and promoting wound healing. After discharge, the factors affecting postoperative recurrence in patients with posterior high complex anal fistula are not regularly changed dressing, history of anal fistula surgery, unclear internal mouth, cutting and wire hanging drainage, which should be paid attention to.
Objective To investigate the choleenterostomy type and the longterm results in treatment of benign diseases of biliary tract. MethodsA total of 614 cases of choleenterostomy from January 1981 to December 2000 were followed up and analysed. The original diseases: 321 were original hepatolithiasis and/or bileduct stricture (52.3%)， 106 congenital cyst of common bile duct (17.3%), 151 iatrogenic bile duct injury (24.6%) and others 36 cases (5.9%). Choledochoduodenostomy was performed in 89 cases and choledochojejunostomy in 525 cases. Five hundred and twentyfour cases have been followed up for 1 to 20 years. The rate of followup was 87.9%. ResultsIn 84.5% of the cases, excellent or good longterm results were achieved. Reoperation rate were 49.4% in cases of choledochoduodenostomy or cystoduodenostomy, 14.2% in sideside (cyst) cholangiojejunostomy and 4.4% in endside cholangiojejunostomy, respectively. Conclusion The choledochoduodenostomy should be abolished. The endside cholangiojejunostomy shoud be the best choice when it is needed to perform choledochojejunostomy in benign bile duct diseases and can promise a satisfactory longterm result.
ObjectiveTo study the clinical effect of silver dressing combined with foam dressing in the treatment of diabetic foot ulcers. MethodsSixty patients with diabetic foot ulcer treated between January 2014 and January 2015 were selected to be randomly divided into experimental group (n=30) and control group (n=30). Patients in the experimental group (n=30) were treated with silver dressing combined with foam dressing which was changed every other day, while patients in the control group (n=30) were treated with 0.1% rivanol gauze and dressing was changed every day. The clinical effcacy of the two groups were compared and analyzed, and the wound closure index and recurrence rate were also analyzed. ResultsThe total effective rate of the experimental group was 96.7%, which was significantly higher than that of the control group (80.0%) (P<0.05), and the wound closure indexes of the experimental group on day 21 [(81.87±4.81)%] and day 28 [(97.28±3.11)%] after the beginning of treatment was significantly higher than those of the control group [(64.06±3.03)%, (86.93±6.11)%] (P<0.05), and the recurrence rate within half a year after treatment of the experimental group was 13.0%, significantly lower than that of the control group (40.0%) (χ2=4.083, P=0.043). ConclusionCompared with traditional wound treatment, silver dressing combined with foam dressing in the treatment of diabetic foot ulcers has advantages with better curative effect, less pain and lower recurrence rate. It is worth clinical promoting.
ObjectiveTo summarize research progress of imaging methods in postoperative efficacy evaluating of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).MethodsThe related literatures of imaging methods in postoperative efficacy evaluating of HCC after the TACE were searched in the PubMed, Web of Science, CNKI, and Wanfang Data databases, etc. The clinical efficacy, advantages and problems of different imaging were analyzed and summarized.ResultsThe contrast-enhanced ultrasound (CEUS) had the higher value in diagnosing of residual or recurrent lesion, but the observation of the multiple or larger lesion was limited on the CEUS. The contrast-enhanced computed tomogaphy (CECT) had the lower diagnostic value for the residual or recurrent lesions as compared with the CEUS due to the artifact of iodine oil deposition. However, the CT perfusion and gemstone spectral imaging parameters could help to predict postoperative efficacy, tumor residue, and tumor recurrence after the TACE. The combination of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI), functional and perfusion imaging had the better diagnostic value, and the liver function could be predicted by the DCE-MRI. The PET/CT had the excellent value in diagnosing of the residual or recurrent lesion and could be used in predicting of the patient’s survival after the TACE. The DSA was the reference standard in diagnosing of the residual or recurrent lesion after the TACE for the HCC patients, however, it had the disadvantages of invasiveness and side effect and the high operational requirements should be emphasized.ConclusionsImaging examinations including ultrasound, CT, MRI, PET/CT, and DSA are widely applied to evaluate curative effect and residual or recurrent lesion of HCC after TACE. However, principles and imaging methods of mentioned above diagnostic methods are inconsistent, as well as results of research are quite different, therefore, clinician should choose the best imaging method according to patient’s condition in diagnosis and treatment.
ObjectiveTo compare short- and medium-term effects of Leonardo da Vinci robot-assisted and traditional mitral valvuloplasty.MethodsWe conducted a retrospective analysis of 74 patients who underwent mitral valvuloplasty in our hospital from January 2015 to March 2017. The patients were divided into two groups according to the mode of operation: a da Vinci group (n=29, 13 males, 16 females at an average age of 52 years) and a routine group (n=45, 18 males, 27 females at an average age of 53 years). The perioperative data of patients in the two groups were compared and analyzed.ResultsThere was no significant difference in sex, age, weight, height, body mass index (BMI), cardiac function (NYHA), hypertension, diabetes, postoperative blood transfusion and postoperative complications between the two groups (P>0.05). The tracheal intubation time, ICU retention time, hospital stay time, blood loss and postoperative drainage in the da Vinci group were shorter or less than those in the routine group (P<0.05). The operation time, cardiopulmonary bypass time and aortic clamping time in the da Vinci group were longer than those in the routine group (P<0.05). Different surgical procedures had no significant effect on left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) and mitral regurgitation (MR) 3 years after operation. There was no interaction between the mode of operation and the time of follow-up. There was no significant difference in echocardiographic evaluation in the same period (P>0.05).ConclusionDa Vinci operation shortens the rehabilitation process of patients compared with traditional surgery. For short- and medium-term follow-up results, there is no difference between Leonardo da Vinci and traditional mitral valve surgeries, and the clinical effect of da Vinci robot-assisted mitral valvuloplasty is satisfactory, which is worthy of further clinical promotion.
ObjectiveTo investigate the curative effect of C-shaped mucosal resection and anastomosis above the dentate line in the treatment of mixed hemorrhoids and its effect on anal function. MethodsA total of 78 patients with degree Ⅳ mixed hemorrhoids treated in Nanjing Liuhe District People’s Hospital from June 2015 to February 2018 were retrospectively collected. The patients were divided into control group (n=39) and observation group (n=39) according to treatment methods. Patients of the control group received traditional procedure for prolapse and hemorrhoids operation, while patients of the observation group received C-shaped mucosal resection and anastomosis above the dentate line. The perioperative indexes (operation time, intraoperative blood loss, hospital stay, etc.), subjective function evaluation indexes (Wexner constipation score, Kirwan grade, etc.), clinical efficacy and recurrence rate were compared between the two groups. The random walking model was used to evaluate the clinical curative effect. ResultsThe intraoperative blood loss [(27.9±3.4) mL vs. (43.2±5.2) mL, P<0.001], 24 h visual analogue scale score [(4.2±1.5) points vs. (5.6±1.5) points, P<0.001], duration of first defecation pain [(22.1±3.2) min vs. (34.2±5.0) min, P<0.001], the time of carrying blood [(4.1±0.4) d vs. (5.7±0.6) d, P<0.001], and the time of edema [(3.2±0.6) d vs. (4.7±0.9) d, P<0.001] in the observation group were shorter (lower) than those in the control group. The difference between pre-and post-operation of Wexner constipation score [(13.2±2.4) points vs. (11.7±2.1) points, P=0.004], resting pressure [(23.1±4.9) mmHg vs. (17.8±3.4) mmHg, P<0.001] and maximum squeeze pressure [(33.5±7.3) mmHg vs. (23.1±5.6) mmHg, P<0.001] in the observation group were significantly higher than those in the control group. There was a long-term correlation between changes in random fluctuating power rate values of Wexner constipation score, Kirwan grade, rectoanal inhibitory reflex positive rate, resting pressure, maximum squeeze pressure and the surgical procedure received by the patient of the two groups. The total effective rate [97.4% (38/39) vs. 66.7% (26/39)] and non-recurrence rate [92.3% (36/39) vs. 76.9% (29/39)] in the observation group were higher than those in the control group, while there was no significant difference in the incidence of total complications between the two groups [5.1% (2/39) vs. 12.8% (5/39), P=0.235)]. ConclusionCompared with PPH, C-shaped mucosal resection and anastomosis above the dentate line for the treatment of degree Ⅳ mixed hemorrhoids can improve the therapeutic effect, reduce postoperative recurrence, maintain anal function and facilitate the recovery of patients.
