ABSTRACT
Objective:To investigate the clinical efficacy and safety of gabapentin or topiramate combined with venlafaxine in the treatment of chronic migraine patients with generalized anxiety disorder.Methods:From June 2018 to February 2020, 127 patients with chronic migraine complicated with generalized anxiety disorder in the Second Affiliated Hospital of Guangxi Medical University were selected. The patients were divided into gabapentin combined with venlafaxine group (observation group, 64 cases) and topiramate combined with venlafaxine group (control group, 63 cases) according to the random number table method, and all patients were treated for 6 months. The headache attack days per month, headache visual analogue scale (VAS), migraine specific quality of life questionnaire V2.1 (MSQ V2.1), headache impact measurement-6 (HIT-6) score, Pittsburgh sleep quality index (PSQI) score were recorded before treatment and 3 and 6 months after treatment.Results:In observation group, 57 cases completed 3 months of treatment, and 53 cases completed 6 months of treatment. In the control group, 56 cases completed 3 months of treatment, and 50 cases completed 6 months of treatment. The headache attack days per month, headache VAS, HIT-6 and PSQI 3 and 6 months after treatment in 2 groups were significantly lower than those before treatment, observation group: (16.31 ± 5.02) and (15.69 ± 6.31) d vs. (22.62 ± 3.27) d, (3.67 ± 1.60) and (1.91±1.05) scores vs. (5.09 ± 1.43) scores, (49.34 ± 11.01) and (47.34 ± 9.05) scores vs. (60.25 ± 11.61) scores, (10.09 ± 2.81) and (9.68 ± 2.74) scores vs. (13.50 ± 2.81) scores; control group: (14.58 ± 7.37) and (9.92 ± 5.07) d vs. (23.05 ± 5.24) d, (4.74 ± 1.15) and (3.16 ± 1.60) scores vs. (5.90 ± 2.06) scores, (42.77 ± 8.02) and (40.09 ± 9.72) scores vs. (59.37 ± 9.08) scores, (9.66 ± 2.71) and (8.62 ± 2.07) scores vs. (14.61 ± 2.79) scores, and there were statistical differences ( P<0.05). The headache VAS 3 and 6 months after treatment in observation group was significantly lower than that in control group, and there was statistical difference ( P<0.05). The functional limitations, function loss, emotional function scores and total score of MSQ V2.1 3 and 6 months after treatment in 2 groups were significantly lower than those before treatment, observation group: (17.62 ± 9.81) and (16.01 ± 5.73) scores vs. (36.96 ± 9.55) scores, (12.17 ± 5.60) and (11.09 ± 3.27) scores vs. (17.06 ± 6.08) scores, (8.42 ± 2.17) and (8.94 ± 1.90) scores vs. (11.40 ± 4.09) scores, (33.24 ± 9.61) and (28.62 ± 5.04) scores vs. (62.75 ± 14.02) scores; control group: (17.08 ± 8.73) and (16.79 ± 5.19) scores vs. (36.82 ± 9.68) scores, (9.04 ± 4.48) and (8.90 ± 3.46) scores vs. (17.26 ±6.01) scores, (6.92 ± 2.61) and (5.15 ± 1.74) scores vs. (11.30 ± 5.47) scores, (31.65 ± 9.17) and (30.66 ± 6.04) scores vs. (62.91 ± 11.18) scores, and there were statistical differences ( P<0.05). There was no significant difference in the effective rate and the incidence of adverse drug reactions 3 and 6 months after treatment between 2 groups ( P>0.05). Conclusions:Gabapentin or topiramate combined with venlafaxine can reduce the degree of headache in chronic migraine patients with generalized anxiety disorder, reduce the number of headache days per month, improve sleep and improve the quality of life. However, the adverse reactions of gabapentin still need to be paid more attention.
ABSTRACT
Objective@#To evaluate the short-term and long-term efficacy of endoscopic submucosal dissection (ESD) in the treatment of early low rectal cancer and precancerous lesions.@*Methods@#Inclusion criteria: (1) Distance from the lower margin of tumor to the anal was ≤ 5 cm. (2) Early low rectal cancers were any size rectal epithelial tumors with infiltration depth limited to the mucosa and submucosa, which were diagnosed by postoperative pathology as high-grade intraepithelial neoplasia or adenocarcinoma of the rectum with infiltration depth of intramucosal or submucosal cancer (M or SM stage). (3) Precancerous lesions included adenoma and low-grade intraepithelial neoplasia of the rectum. (4) Patients received ESD treatment. Patients with tumor invasion depth over submucosa by pathology were excluded. From January 2008 to January 2018, 63 patients meeting the above criteria in Peking University First Hospital were enrolled in this descriptive cohort study. The disease characteristics, clinical manifestations, pathological types, treatment time, hospitalization time, en bloc resection rate (resection of the whole lesion), complete resection rate (both the horizontal and vertical incision margins were negative), postoperative complications and follow-up results were analyzed. Cummulative survival rate was calculated by Kaplan-Meier.@*Results@#The diameter of the lesion was (29.0±23.4) mm and the distance from the lesion to the anus was (2.7±1.8) cm. The median operation time was 45.0 (range, 10.0 to 360.0) minutes, the median hospitalization time was 3.0 (range, 2.0 to 12.0) days, en bloc resection rate was 100%, complete resection rate was 96.8% (61/63), and 1 case (1.6%) had postoperative bleeding. The follow-up rate was 87.3% (55/63) and the median follow-up time was 57.9 (range, 15.6 to 121.1) months. No local recurrence was found during the follow-up period and the 5-year survival rate was 100%.@*Conclusion@#Short- and long-term efficacy of ESD are quite good in the treatment of patients with early low rectal cancer and precancerous lesions.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the clinical efficacy of endoscopic submucosal dissection (ESD) and surgical resection for early gastric cancer (EGC). Method The retrospective case-control study was conducted. Clinical and pathological data of 246 patients who were diagnosed as early gastric cancer and received ESD or surgery for EGC at Peking University First Hospital from 2010 to 2015 were collected, including 171 males and 75 females with average age of (63.6±10.8) years. Eighty-one patients received ESD according to the following indications: no peritoneal lymph node metastasis in preoperative CT; differentiated mucosal cancer without ulcer findings, irrespective of tumor size; differentiated mucosal cancer with diameter ≤30 mm and ulcer; differentiated minimal submucosal invasive cancer (≤500 μm from the muscularis mucosa) with diameter ≤30 mm and without ulcer; undifferentiated mucosal cancer with diameter ≤20 mm and without ulcer; high grade intraepithelial neoplasia with diameter >20 mm; mucous lesion recurrence after EMR without chance of EMR again. One-hundred and sixty-five cases received surgery according to the findings of peritoneal lymph node metastasis in preoperative CT or the growth of carcinoma beyond the expanding criteria of ESD (surgery group). En block resection rate (removing all the lesion at once) and curative resection rate [standard: negative horizontal and vertical surgical margins; negative vessel carcinoma embolus; pT1a and pT1b (SM1); lesion diameter <3 cm with differentiated type, pT1a with ulcer or pT1b(SM1); lesion diameter <2 cm with undifferentiated type, pT1a without ulcer] were compared between two groups. According to pathological results, including tumor location, macrographic type, size, pathological type, differentiated type, invasive depth, surgical margin, vessel carcinoma embolus and lymph node metastasis, all the patients meeting the ESD curative resection criteria in both groups were subgrouped in order to compare the baseline information, surgical conditions, postoperative complications, recovery, follow-up and survival. The end of follow up was December 2016.</p><p><b>RESULTS</b>The en block resection rate was 93.8%(76/81), while curative resection rate was 91.4% (74/81) in ESD group. The en block resection rate and curative resection rate was both 100% in surgery group. According to the pathological results, 170 cases were confirmed to be in accordance with the curative resection standard, including 74 cases in ESD group and 96 cases in surgery group. Subgroup analysis showed that ESD group had older cases (t=2.939, P=0.004) and more cases with lesion in upper 1/3 of stomach (χ=8.992, P=0.011), while no significant differences in tumor size, invasion depth, degree of differentiation (t=1.875, 2.393, 3.074, all P>0.05) were observed. Compared to surgery group, ESD group had significantly shorter operative time [(76.4±46.3) minutes vs. (271.9±92.6) minutes, t=17.950, P=0.000], shorter fasting period [(3.2±1.4) days vs. (8.8±5.4) days, t=9.801, P=0.000], shorter hospital stay [(9.0±5.8) days vs. (22.1±9.1) days, t=11.471, P=0.000], less costs [(2.6±2.2) ten thousand yuan vs (7.4±3.0) ten thousand yuan, t=12.235, P=0.000] and lower morbidity of early-stage postoperative complication [1.4%(1/74) vs. 20.8%(20/96), χ=14.502, P=0.013]. One-hundred and sixty-two of 170 patients (95.3%) were followed up for median time of 28 months (range, 11 to 84 months). The recurrence rate was 2.7% (2/74) in ESD group and 4.2% (4/96) in surgery group respectively without significant difference(χ=1.787, P=0.409). Five-year overall survival rate was 97.5% and 96.5% respectively without significant difference as well (χ=0.115, P=0.735).</p><p><b>CONCLUSIONS</b>ESD is an effective and safe treatment of early gastric cancer. It can be used as the first protocol for well-differentiated mucosal or SM1 EGC without ulcer as well as undifferentiated mucosal EGC with diameter less than 2 cm.</p>
ABSTRACT
Objective To investigate the efficiency and safety of endoscopic submucosal dissection (ESD)for rectal neuroendocrine neoplasm(NEN). Methods A retrospective analysis was performed on data collected from 58 consecutive patients with rectal NEN,who underwent endoscopic ultrasonography and followed by ESD from January 2006 to January 2016 at Peking University First Hospital. Patients′endoscopic and pathological features, clinical manifestations, R0 resection rate and follow-up results were studied. Results En bloc resection was achieved for all of the 58 lesions with a mean diameter of 7.6 mm(range 3.0-18.0 mm). The complete resection rate was 94.8%(55/58). One patient showed postoperative bleeding. The diameter of lesion more than 15 mm increased the risk of non-R0 resection(P<0.05). During the mean follow-up of 3.2 years(range 1.2-11.2 years), all patients remained free from local recurrence. However,distant metastasis was detected in 1 NEN G2 patient with lymphatic invasion(1.7%). Conclusion ESD is effective for treatment of rectal NEN with diameter less than 15 mm and causes less complications. Tumor features and stage determine the risk of distant metastasis,so long-term follow-up is essential.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical efficacy of endoscopic therapy for early colorectal cancer.</p><p><b>METHODS</b>Clinical data of 113 early colorectal mucosal carcinoma or submucosal carcinoma receiving endoscopic therapy were retrospectively analyzed and compared with 39 early colorectal cancer cases receiving surgery during the same time.</p><p><b>RESULTS</b>All the cases were well-moderately differentiated adenocarcinoma. Size of tumors in endoscopic group was (26.2±21.5) mm, and that was (30.9±24.3) mm in surgery group (P=0.257). Baseline data between the two groups were not significantly different (all P>0.05). Significantly shorter median operating time [15.0 minutes vs. 203.0 minutes, χ=69.322, P=0.000] and median hospital stay [3.0 days vs. 17.0 days, χ=76.180, P=0.000] were observed in endoscopic group compared with surgery group. The en bloc resection rate, curative resection rate, lymph node metastatic rate and complication rate were not significantly different between two groups (all P>0.05). Ten patients in endoscopic group were referred to additional surgery for deep invasion and/or incomplete resection, of whom 7 received radical surgery, and the other 3 cases without radical surgery did not develop recurrence during follow-up of (20.5±0.9) months. After follow-up for (17.5±15.8) months, the local recurrence rate was 5.3% (6/113) in endoscopic group and 0 (0/39) in surgery group without significant difference (χ=0.983, P=0.321). There was no significant difference in 5-year tumor-free survival rate between two groups (91.8% vs. 97.0%, χ=1.533, P=0.216).</p><p><b>CONCLUSION</b>Endoscopic therapy possesses shorter operating time, shorter hospital stay and similar efficacy as compared to surgery in the treatment of early colorectal cancer.</p>
ABSTRACT
Objective To evaluate safety and efficacy of endoscopy therapy for early colorectal carcinoma of different types. Methods Clinical data of 113 patients with early colorectal carcinoma who were treated with different endoscopic therapies including polypectomy,EMR and ESD(ESD with snare and standard ESD)were retrospectively analyzed. The size, en bloc resection rate, curative resection rate, procedure time,associated complications and recurrence rate were compared among groups. Results Eleven pedunculated lesions were treated with polypectomy or EMR, which were en bloc resected and curative resected with no complication or local recurrence. Nineteen semi-pedunculated lesions were treated with EMR or ESD with no complications. Lesions treated with EMR were smaller than those of ESD(P=0.026), and had a lower en bloc resection rate[77.8%(14/18)VS 1/1,P=1.000]. The difference of curative resection rate and recurrence rate between groups was not significant(P>0.05). Eighty-three sessile lesions were treated with all three procedures.Lesions treated with ESD were larger than EMR(P=0.000),with a higher curative resection rate than EMR[95.5%(42/44)VS 77.8%(28/36),P=0.041]and a longer procedure time than EMR(P=0.000). There were no significant difference in severe complications[9.1%(4/44)VS 0],en bloc resection rates and recurrence rates(P>0.05). Ten lesions treated with ESD-S had a medium size between EMR and standard ESD group, with a significant shorter procedure time than standard ESD group(36.9 ± 24.7 min VS 120.4 ± 152.3 min, P=0.004).They were en bloc resected and complete resected. Conclusion Endoscopic treatment is safe and effective for early stage colorectal carcinoma. In order to get en bloc curative resection,endoscopists should carefully choose a suitable technique based on the macroscopic morphology of lesions. ESD-S can be used as a transitional method from EMR to ESD.
ABSTRACT
Objective To assess the efficiency and safety of endoscopic submucosal dissection (ESD)on treatment of colorectal lesions. Methods Clinical data of 163 patients with colorectal lesions, who underwent ESD at Endoscopy Center of Peking University First Hospital from June 2012 to June 2016, were retrospectively analyzed. The clinicopathologic features, the rate of en bloc resection, complete resection,complication and recurrence were reviewed. Results Among the 163 colorectal lesions,118 were mucosal lesions and 45 were submucosal ones. The mucosal lesions included 31 cases of protruding type,22 of flat type and 65 of laterally spreading tumor(LST). The submucosal lesions were all protruding type. The median lesion diameter was 2.2(2.0)cm, median operation time was 42(53)min. En bloc resection rate was 92.6%(151/163),and complete resection rate was 86.5%(141/163). The risk factor related to en bloc resection rate and complete resection rate was tumor size(P<0.05).Complications occurred in 4 cases, including 2 cases of intraoperative bleeding and 1 case of delayed bleeding who received endoscopic hemostasis therapy,and 1 patient with delayed perforation,which was managed by emergency surgery. Four recurrences were observed in 135 cases during follow-up, of which 3 were cured by additional endoscopic treatment,and 1 by surgery. Conclusion ESD is a safe and effective, but less invasive technique for colorectal lesions. Favorable long-term clinical outcomes can be achieved when en bloc curative resection is performed.
ABSTRACT
Objective To compare the efficiency of 18F-FDG PET/CT and contrast enhanced ultrasound (CEUS) in detection of HCC recurrence after surgery or radiofrequency ablation (RFA).Methods Twenty-seven HCC patients (22 males,5 females; average age:47 years) were included in this study,of which 15 patients underwent surgery and 12 patients underwent RFA therapy.18F-FDG PET/CT and CEUS were performed within 2 weeks in all patients to detect recurrence.Final diagnosis was made by pathology or clinical follow-up (＞6 months),and the sensitivity,specificity and accuracy of 18F-FDG PET/CT and CEUS were calculated and compared.McNemar test was used for data analysis.Results Twenty-five patients were diagnosed with HCC recurrence,including 11 cases with extrahepatic metastases.Another 2 patients had extrahepatic metastases without HCC recurrences.The sensitivity,specificity and accuracy in detection of liver lesion with 18F-FDG PET/CT were 92.0％ (23/25),2/2 and 92.6％ (25/27),respectively.While with CEUS,the corresponding values were 60.0％ (15/25),2/2 and 63.0％ (17/27),respectively.In CEUS positive group,the sensitivity and accuracy were 100％(15/15) for both methods.In CEUS negative group,the sensitivity,specificity and accuracy of 18 F-FDG PET/CT in detection of liver lesion were 8/10,2/2 and 83.3％(10/12),respectively.The sensitivity and accuracy of 18F-FDG PET/CT were significantly higher than those of CEUS (0,16.7％(2/12) ; x2 =5.373,5.250,both P＜0.05).Moreover,the sensitivity of 18 F-FDG PET/CT in detecting extrahepatic metastasis was 100％ (13/13).Conclusions 18 F-FDG PET/CT is more sensitive and accurate than CEUS (especially in CEUS negative cases) in detecting recurrence of HCC after surgery or RFA.18F-FDG PET/CT also could be useful for detection of extrahepatic metastasis.
ABSTRACT
Objective To investigate the ultrasound characteristics of pseudothrombophlebitis.Methods The ultrasound characteristics of thirty-two popliteal cyst cases with pseudothrombophlebitis which were confirmed by MRI or puncture were retrospectively analyzed.The former group was matched with a case control group of sixty-four patients with asymptomatic popliteal cysts,the ultrasound images were comparative analysis between the two groups.Results Compared to the control group,both the length and width of the case group were larger [(12.4 ± 4.7) ×(2.5±0.4)cm vs (5.3±2.9) × (1.2±0.4)cm,P ＜ 0.001],and there were 18(43.8％) cases with the cysts extension into the calf.The case group were more prone to show cyst with poor ultrasound penetration or solid-cystic echo (78.1％ vs 9.4％,P =0.000),which were diagnosed as popliteal cyst with hematoma or infection.Six cases of case group showed irregular anechoic area surrounding the inferior border of the cysts,which were diagnosed as ruptured popliteal cyst,no similar imaging detected in the control group(P =0.001).Both the two group showed septation in the cyst,but it did not differ significantly(P ＞0.05).Conclusions Ultrasonography is helpful to the diagnosis of pseudothrombophlebitis,the ultrasound characteristics include large cyst extension into the calf,cyst with poor ultrasound penetration or solid-cystic echo and irregular anechoic area surrounding the inferior border of the cysts.
ABSTRACT
Objective To investigate the feasibility and method of Sonazoid contrast-enhanced ultrasound (CEUS) for diagnosis of liver fibrosis/cirrhosis. Methods Liver cirrhosis was induced by oral administration of carbon tetrachloride to male wistar rats. Both conventional ultrasound and Sonazoid-CEUS were applied to each rat, respectively. Qualitative and quantitive analysis were performed, and the diagnostic performance of Sonazoid-CEUS on diagnosis of liver fibrosis/cirrhosis were analyzed. Results Twenty four rats were divided into three groups as group 1 (normal liver, n =5),group 2(fibrotic liver, n =6) and group 3 (cirrhotic liver, n =13). The Kupffer phase findings of Sonazoid-CEUS were as following: the enhancement level of normal liver was significantly higher than those of fibrotic/cirrhotic liver, and the difference between liver and spleen of fibrotic/cirrhotic liver was larger than those of normal liver with significant difference. Sonazoid-CEUS showed higher performance on diagnosis of liver fibrosis/cirrhosis than conventional US, with the sensitivity, specificity and accuracy were 84.2％, 100％ and 87.5％,respectively. The quantification data of liver and spleen further proved the characteristic findings of normal liver,fibrotic liver and cirrhotic liver in Kupffer phase. Conclusions Decrease of liver enhancement and increase of the difference between spleen and liver during Sonazoid-CEUS Kupffer phase are the typical findings of liver fibrosis/cirrhosis.
ABSTRACT
Objective To analyze the characteristics of gastric stromal tumors(GST)under endoseopic ultrasonography(EUS)according to its aggressive risks.Methods The clinical data of 36 patients with GST,who underwent surgery from July 1997 to July 2007,were analyzed retrospectively.All the patients underwent EUS before operation and were classified according to Fleether's 4-tier system to predict the aggressiveness of the tumors.The features of the tumor under EUS including its size,ulceration,border,echo charateristies and growth pattern were recorded and the difference between each tumor group were analyzed by ANOVO and rank sam test.Results The mean maximal diameter of GST Was 7.3 cm(range 1.0-20.0 cm),and the size of tumors with hiisher aggressiveness risk Was significantly larger than that with lower risk(P＜0.01).The mucosal ulceration,obscure border,irregular shape and echo heterogeneity were more commonly seen in the groups with higher risk(P＜0.05).There Was no difference in the internal echo and growth pattern of GST between different groups.Conclusion EUS features are useful in differentiation of the aggressiveness risk of the GST.and guide the management of the tumors.
ABSTRACT
Objective To study on the effectiveness of endoscopic ultrasonography (EUS) in diagnosing common bile duct (CBD) stones. Methods Accuracies for the diagnosis of choledocholithiasis by abdominal ultrasonography ( B-US) and computed tomography (CT) are compared with those by EUS in 45 patients. Final diagnosis is determined by endoscopic retrograde cholangiography ( ERC) with or without sphincterotomy ( EST) or operative exploration. Results Forty-three out of 45 patients with choledtx-holithia sis were diagnosed by EUS, of them 2 patients with slight dilation of common bile duct in which stones were confirmed in the proximal part of common bile duct by EST. In 2 out of 43 patients EST and operation diagnosed cholecystolithiasis instead of choledocholilhiasis. The sensitivity and the positive predictive value are both 95%. With 41 patients choledocholithiasis were confirmed by EUS, the sizes of stone were diameter ≥ 10mm in 5 patients, 6-9 mm in 10 patients and ≤5mm in 26 patients. Four out of 45 patients were suspected to have CBD stones and 2 patients had tumor in periampullar area by B-US. Three patients were diagnosed to have CBD stone and 1 patient was suspected to have tumor in peri-ampullar area by CT. Conclusions EUS appears to be the best diagnostic tool for the diagnosis of choledocholithiasis compared with other noninvasive procedures such as B-US and CT. EUS is at least as sensitive as ERC especially in diagnosis of small CBD stones.
