ABSTRACT

Objective@#To evaluate the accuracy of endoscopic titanium clip localization combined with CT three-dimensional reconstruction for the control of incision margin in early gastric cancer under laparoscopy.@*Methods@#A prospective analysis was made for gastric cancer whose lesions were located in the middle of the stomach and T stage was 1 to 2 from October 2017 to January 2019 at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital. Totally 25 patients were eventually enrolled in the study. There were 17 males and 8 females aging of (63.6±7.2) years (range: 48 to 77 years). All cases were treated with titanium clip localization under endoscope combined with CT three-dimensional(3D) reconstruction to construct a virtual panorama of gastric cavity and lesions, and to design surgical margins. Laparoscopic surgical resection was performed according to the surgical margins designed before operation. The distance from the gastric angle to the origin of the minor curvature of the incisional margin, the distance from the gastric angle to the the center of lesion and the distance of the upper incision margin were measured under three-dimensional CT reconstruction and under actual specimen. Paired t test was used to compare the three distances measured by two methods.@*Results@#The measured distances from the gastric angle to the center of the lesion and the proximal incisional margin under 3D reconstruction CT were according to the measured values of actual specimens ((2.67±1.38) cm vs. (2.83±1.56) cm, t=1.51, P=0.14; (5.23±0.60) cm vs. 5 cm, t=1.93, P=0.07); the measured distances from the gastric angle to the origin of the minor curvature of the incisional margin under CT 3D reconstruction were different with the measured values of solid specimens ((5.94±0.94) cm vs. (6.37±0.90) cm, t=3.52, P=0.00).@*Conclusion@#The method of titanium clip localization combined with CT 3D reconstruction can provide a feasible laparoscopic localization method and incision edge solution for T1 to T2 gastric central cancer.

ABSTRACT

Objective To investigate the association between helicobacter pylori (H.pylori) infection and the prevalence of Crohn's disease (CD).Methods 107 patients who diagnosed as CD were selected.H.pylori infection was detected by rapid urea test by endoscopy.H.pylori infection rate was compared between CD group and control group,followed by a subgroup analysis based on lesion position of CD.Results There were 107 patients in the CD group and 92 patients in the control group.There were no statistically significant differences in age,sex and BMI between the CD group and control group(all P > 0.05).However,the CD group showed significantly higher rates of smoking history(37.38%) and alcohol intake (19.63%) compared with the control group(x2 =7.40,P < 0.01;x2 =7.64,P <0.01).The H.pylori infection rate in the CD group was 28.97%,which was significantly lower than 60.87% in the control group (x2 =20.46,P < 0.01).The H.pylori infection rate in the four subgroups were also significantly lower than those in the control group (x2 =6.88,P < 0.01;x2 =5.48,P < 0.05;x2 =13.44,P < 0.01;x2 =7.20,P < 0.01).However,there was no statistically significant difference in the H.pylori infection rate among these four subgroups (x2 =0.15,P =0.98).Conclusion H.pylori infection may play a protective role in the patients with CD and there is no significant association between potential protective effect and the change of lesion position.

ABSTRACT

Objective Explore the differences in effectiveness and safety between endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) for early esophageal cancer (EEC).Methods Papers published from January 1990 to December 2012 in Medline,Embase,Cochrane library,Wanfang,VIP and CNKI were searched in English and Chinese respectively to identify the studies comparing ESD with EMR for EEC.Meta-analysis for each outcome of the included studies that were identified by the inclusion criteria and the exclusion criteria was conducted using software Revman 5.1.Outcome measures consisted of three effectiveness-relevant measures (rates of en bloc resection,curative resection,local recurrence) and four safety-relevant measures (bleeding,perforation,stenosis and operation time).Results A total of 8 non-randomized retrospective cohort studies (five full-text and three abstracts) were included.Meta-analysis showed significantly higher rates of en bloc resection [98.36% (360/366) vs.41.79% (252/603),P < 0.01],curative resection [90.81% (168/185) vs.50.65 % (194/383),P < 0.01] and perforation [4.51% (21/466) vs.1.25% (8/640),P =0.03] in ESD group compared with EMR group,and the rate of local recurrence was significantly lower in ESD group [0.55% (2/366) vs.13.76% (83/603),P <0.01].There were no significant differences in the rates of bleeding [0.21% (1/466) vs.0.63%(4/640),P =0.41] or stenosis [10.48% (39/372) vs.10.15% (41/404),P =0.89].Conclusion Compared with EMR,ESD showed obvious advantages of effectiveness and resemble risks for endoscopic resection of EEC,therefore ESD should be the first choice for endoscopic treatment of EEC.
