ABSTRACT
Objective:To investigate the prognostic factors of patients with pancreatic body and tail carcinoma.Methods:The clinical data of 64 patients with pancreatic body and tail carcinoma who underwent surgical resection or endoscopic ultrasound biopsy and were pathologically confirmed in the Second Affiliated Hospital of Jiaxing University from January 2013 to March 2020 were retrospectively analyzed. Age, gender, diabetes mellitus, serum CEA and CA19-9 levels at initial diagnosis, tumor site, maximum tumor diameter, TNM stage and treatment method were collected. Kaplan-Meier method was used to draw survival curve, and Log-rank test was used to analyze survival rate. Univariate and multivariate Cox proportional risk regression models were used for prognostic analysis.Results:Among the 64 patients, 24 patients were complicated with diabetes; serum CEA level was increased in 36 cases, and serum CA19-9 level was increased in 46 cases; 8 cases were in TNM stage ⅠA, 4 cases were in ⅠB stage, 4 cases were ⅡA stage, 4 cases were in ⅡB stage, 8 cases were in Ⅲ stage, and 36 cases were in Ⅳ stage. Symptomatic treatment was performed in 18 cases, chemotherapy combined with immunotherapy were in 18 cases, and surgical comprehensive therapy (surgery combined with chemotherapy and immunotherapy) were in 26 cases. Univariate analysis showed that diabetes mellitus, serum CEA and CA19-9 levels, TNM stage and treatment mode were related factors affecting the prognosis of patients with pancreatic body and tail carcinoma (all P value <0.05). Multivariate analysis indicated that TNM stage ( HR=2.536) and surgical comprehensive therapy ( HR=0.285) were the independent factors affecting the prognosis of patients with pancreatic body and tail carcinoma ( P<0.05). Median survival was 25 months (95% CI 21.416-28.584) for patients with TNM stage Ⅲ+ Ⅳ pancreatic body and tail carcinoma treated with surgical comprehensive therapy, 11 months (95% CI 7.246-14.754) for patients treated with chemotherapy combined with immunotherapy, and 6 months (95% CI 3.819-8.181) for patients treated with symptomatic treatment; the median survival time of patients with surgical comprehensive therapy was significantly longer than that of patients with chemotherapy combined with immunotherapy and symptomatic treatment, and the difference was statistically significant ( P<0.05). Conclusions:TNM stage and surgical comprehensive therapy were the prognostic factors affecting the prognosis of patients with pancreatic body and tail carcinoma, and surgical comprehensive therapy may be the best choice for long-term survival of patients.
ABSTRACT
Objective:To study the feasibility for transumbilical single-incision laparoscopic appendectomy (SILA) with conventional laparoscopic instruments, and compare SILA with the traditional three-port laparoscopic appendicectomy (LA).Methods:The clinical data of 113 patients with acute appendicitis from January 2018 to August 2020 in the Second Hospital of Jiaxing City were retrospectively analyzed. Among them, 61 patients received traditional three-port LA (three-port LA group), 52 patients received transumbilical SILA (SILA group). The operative time, intra-operative blood loss, surgical complications, length of hospital stay and hospitalization costs were recorded. Pain score 6 h after operation was assessed by visual analogue scale. C-reactive protein (CRP) on the first day after operation was detected. All patients were followed up for 1 month.Results:In 2 groups, all patients did not suffered from the conversion to open operation or multi-port method, massive bleeding and accessory injury during the operation. Moreover, severe pain, severe incision infection, residual abdominal abscess and incisional hernia did not occur. Patients in SILA group had more hidden abdominal scars. there were no statistical differences in operative time, intra-operative blood loss and CRP on the first day after operation between 2 groups ( P>0.05); the rate of moderate pain degree 6 h after operation, length of hospital stay and hospitalization costs in SILA group were significantly lower than those in three-port LA group: 15.38% (8/52) vs. 34.43% (21/61), (3.63 ± 1.22) d vs. (4.31 ± 1.38) d and (8 802 ± 1 466) yuan vs. (9 559 ± 1 617) yuan, and there were statistical differences ( P<0.05 or <0.01). Conclusions:The transumbilical SILA with conventional laparoscopic instruments is safe and feasible, the scar is more difficult to see, the cosmetic effect is much clearer, and the length of hospital stay is shorter.
ABSTRACT
ObjectiveTo investigate the value of endoscopic ultrasonography (EUS) in the diagnosis of pancreatic space-occupying diseases. MethodsA total of 85 patients with suspected pancreatic space-occupying diseases who were treated in The Second Affiliated Hospital of Jiaxing College from January 2015 to January 2017 were enrolled. Surgical pathological results or follow-up results were used as the gold standard for evaluating the value of EUS and EUS-guided fine needle aspiration (EUS-FNA) in the diagnosis of pancreatic space-occupying diseases. The chi-square test was used for comparison of categorical data between groups. ResultsEUS had an imaging detection rate of 96.7% (59/61), a specificity of 100% (24/24), and an accuracy rate of 97.6% (83/85) in the diagnosis of pancreatic space-occupying diseases; EUS had significantly higher detection rate and accuracy rate than abdominal ultrasound, computed tomography, and magnetic resonance imaging (detection rate: χ2=4.344, 3.873, and 15.445, all P＜0.05; accuracy rate: χ2=6.675, 8.685, and 17389, all P＜0.05). EUS-FNA had a detection rate of 81.8% (45/55) and an accuracy rate of 81.0% (47/58). Among the patients who underwent surgery to have pathological results, the overall coincidence rate of preoperative EUS-FNA was 84.2% (16/19). ConclusionCompared with conventional imaging examinations, EUS has a higher diagnostic accuracy for pancreatic space-occupying diseases, and EUS-FNA can further clarify the nature and pathological type of space-occupying lesions. EUS may help with the early diagnosis and treatment of pancreatic tumors.
ABSTRACT
Objective@#To detect the expression of B cell transposition gene 3(BTG3) in pancreatic ductal adenocarcinoma(PDAC), and explore its relationship with postoperative recurrence and metastasis of tumor.@*Methods@#Six self-paired frozen PDAC specimens and 3 normal pancreatic tissues from the Second Hospital of Jiaxing Affiliated to Jiaxing University were collected and the expression of BTG3 was detected by qPCR. Ten normal pancreatic tissues and 52 cases of PDAC tumor and paracarcinomatous tissues from the Second Hospital of Jiaxing Affiliated to Jiaxing University were collected from June 2009 to December 2016. The expression of BTG3 and relationship among BTG3 and clinicopathological characteristics of PDAC and patients′ prognosis were detected and analyzed using immunohistochemistry.χ2 test, Kaplan-Meier method and Cox regression model were used to analyzed the data.@*Results@#The results of qPCR showed that expression level of BTG3 in PDAC (0.63±0.17) was lower significantly than that in paracarcinomatous (0.96±0.04) and normal tissues (1.00)(t=4.673, 5.502; both P<0.05). Immunohistochemistrv showed that BTG3 mainly expressed in the cytoplasm.The high expression rate of BTG3 in PDAC tumor tissues was 25.0%(13/52), which was remarkably lower than that in paracarcinomatous tissues(65.4%) and normal liver tissues(7/10)(χ2=17.120 and 5.849, both P<0.05). The low expression of BTG3 in PDAC was correlated with primary tumor, and TNM stage(χ2=7.704, P=0.006; U=154.000, P=0.018, respectively). Survival analysis showed that disease free survival rate of patients with low expression of BTG3 was significantly less than that with high expression(χ2=192.493, P<0.01). The Cox multivariate analysis demonstrated that low expression of BTG3 was independent risk factors for disease free survival in patients with PDAC after a curative resection(RR=3.366, 95%CI: 1.040-10.889, P=0.043).@*Conclusion@#BTG3 may be involved in the occurence and development of tumor, and its low expression may be associated with poor prognosis in patients with PDAC.
ABSTRACT
Objective To summarize the computed tomography (CT) features of small intestinal obstruction caused by primary abdominal cocoon and investigate the essentials of diagnosis and differential diagnosis.Methods The retrospective descriptive study was adopted.The clinical data of 1 patient with small intestinal obstruction caused by primary abdominal cocoon who was admitted to the Second Affiliated Hospital of Jiaxing University on October 6,2014 were collected.The patient underwent abdominal CT on admission and at 10 hours after admission.The patient received emergency exploratory laparotomy after preoperative preparation,and then postoperative regular symptomatic treatment and pathological examination.Results of abdominal CT were observed,including imaging features of abdominal masses,extent of small intestinal obstruction,situation of intestinal tube within the masses,vessel distribution in the mesentery and fibrous capsules around the mesentery.Situation of operation,routine blood test,biochemical indicator,blood coagulation indexes,postoperative recovery,complications,results of pathological examination and situation of patient during follow-up were recorded.The follow-up by telephone interview and outpatient examination was applied to the patient till October 31,2015,including detecting the dietary,with or without symptoms of abdominal pain and distension,haematemesis and hematochezia,routine blood retest,liver function,renal function and CT.Results Results of abdominal CT on admission:(1) coronal plain scan of abdominal CT showed that there were signs of incomplete intestinal obstruction,and local small intestinal dilatation and gas accumulation in left abdominal region without specific sign.(2) Plain scan of abdominal CT showed that there were the coated sign with thickened fibrous capsules around the intestinal tube, banana shape ' with agglomerate and expanding-distortion intestinal tube and aggregative,stretching and twisting mesentery with abnormal vessel distribution.(3) Sagittal reconstruction images of abdominal CT showed that a huge mass consisted of fibrous capsules as cocoon and agglomerate and expanding-distortion intestinal tube was petal-like and fixed on posterior abdominal wall.(4) Coronal reconstruction images of abdominal CT showed that agglomerate and expanding-distortion intestinal tube was annularly surrounded by uneven thickness fibrous capsules with abnormal vessel distribution in the mesentery.Results of abdominal CT at 10 hours after admission:(1) coronal plain scan of abdominal CT showed that small intestinal obstruction was obviously exacerbated and expanding intestinal tubes were increased and aggravated.(2) Plain scan of abdominal CT showed that a typical sign of small intestinal obstruction was exacerbated and there were multiple air-fluid levels in the agglomerate and expanding-distortion intestinal tube with fluid and gas accumulation.Patient underwent successful enterodialysis + resection of fibrous capsules.During operation,a huge mass in the intestine from suspensory ligament of duodenum to ileocecum was fixed on posterior abdominal wall and surrounded by dense,smooth and white fibrous capsules,partial colon was also surrounded by fibrous capsules and greater omentum was missing.Patient received the postoperative supporting treatments of fasting,anti-infection and inhibition of acid.Number of white blood cells,absolute value and percentage of neutrophils,levels of high-sensitivity C-reactive protein and procalcitonin were 17.10 × 109/L,15.70 × 109/L,91.5％,127.49 mg/L and 1.370 μg/L by blood routine retest at postoperative day 1,respectively.Patient had normal liver,renal and coagulation functions.Fluid diet intake at postoperative week 1 was gradually replaced by normal diet intake.Patient had normal liver and renal functions by blood routine retest at postoperative day 10 and a good recovery without intestinal fistula,abdominal and pulmonary infections and other complications.Postoperative pathological examination showed that gross specimen was mainly composed of cocoon-shaped,grayish white and tough fibrous capsules.Fibrous capsules were consisted of proliferative fibrofatty tissues by microscope observation,with small vascular hyperplasia and large numbers of the inflammatory cell infiltration.Patient was diagnosed with small intestinal obstruction caused by primary abdominal cocoon after operation,and followed up for 1 year with normal diet intake and without abdominal pain and distension,nausea and vomiting,melena and discomfort.There was normal blood routine retest,liver and renal functions and distribution of the intestine in abdomen by CT examination.No dilatation of the intestinal tube was found and strip-like high density shadow in ileocecum was detected and considered as remnant fibrous capsules.Conclusion Imaging features of small intestinal obstruction caused by primary abdominal cocoon include agglomerate and expanding-distortion intestinal tube fixed on abdomen,partial intestinal tubes dilatation,intestinal fluid accumulation and air-fluid level,aggregative,stretching and twisting mesentery with abnormal vessel distribution,thickened fibrous capsules around intestinal loops and among intestinal tubes.
ABSTRACT
Objective To study the expressions of metadherin (MTDH),E-cadherin and β-catenin in the tissues of hepatocellular carcinoma (HCC),to investigate the relationship between them and the clinical-pathological features,and to evaluate the prognostic values after surgical resection for hepatocellular carcinoma.Methods The protein expressions of MTDH,E-cadherin and β-catenin were studied by immunohistochemistry in tumor tissues of 107 HCC patients who underwent curative surgical resection.The data were correlated with the clinical-pathological data,tumor free time and recurrence rate.Results Positive expression of MTDH and nuclear β-catenin accumulation were correlated with the Edmondson grade (P＜0.05) and decreased E-cadherin expression was correlated with the preoperative serum level of α-fetoprotein (AFP) (P＜0.05).All these expressions were associated with a shorter tumor-free survival and a higher recurrence rate (P＜0.05).Positive MTDH expression was correlated with decreased E-cadherin expression and nuclear β-catenin accumulation (P＜0.05).On Cox regression analysis,MTDH was an independent risk factor of tumour recurrence (RR=3.431,CI=1.254～ 7.318).Conclusions Positive MTDH expression,decreased E-cadherin expression,and nuclear β-catenin accumulation indicated a higher recurrence rate after curative surgical resection for HCC.MTDH was an independent risk factor of recurrence.
ABSTRACT
Objective To explore the value of endoscopic nasopancreatic drainage (NPD) in the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) in a high-risk population.Methods From April 2009 to February 2012,a total of 105 cases of PEP high risk population were collected and divided into non NPD group (n=58) and NPD group (n=47) according to the situation during the endoscopic retrograde cholangiopancreatography(ERCP) operation.NPD was placed in NPD group,the head of the drainage passed the neck of pancreas under X-ray.Nasobiliary drainage or no drainage was assigned to the group of non NPD group according to the situation during operation.x2 test and t-test were performed for comparing and analyzing the clinical data before and post operation,the incidence and risk ratio of PEP between the two groups.Results Twenty-four hours after ERCP,the mean level of serum amylase at 24 h (t=2.419),the degree of abdominal pain (t3h=2.585,t24h=7.236) and relief time (t=4.996) of NPD group were better than those of non NPD group (all P＜0.05).The incidence of PEP in NPD group was 6.7％(3/45) and non NPD group was 29.3 ％ (17/58),the incidence of PEP in the NPD group was significantly lower than that in the non NPD group (x2 =8.304,P＜0.01),and the relative risk was 0.172 (95％CI:0.047 to 0.632,P＜0.01).Conclusion The regular placement of endoscopic NPD is a practical,effective and easy way to prevent PEP in high risk population.
ABSTRACT
Objective To investigate the relationship between-160C/A single nucleotide poly-morphism(SNP) in the CDH1 gene promoter and protein expression in hepatocellular carcinoma. Methods Samples were taken from 34 patients with hepatocellular carcinoma and -160 C/A SNP of CDH1 gene promoter was detected by blood specimens adopting direct DNA sequencing. The expres-sion of E-cadherin which encoded by CDH1 gene was determined by paraffin-embedded tissue using immunohistochemistry and the association between -160 C/A SNP and protein expression was ana-lyzed. Results The high and low expression of E-cadherin was observed in 18 cases(52.9%) and 16 cases(47.1%). In these two groups, the difference of the incidence between CC genotype and CA, AA genotype was statistically significant(P<0.05) whereas there was no marked difference between CA and AA genotype. The difference of both A and C allele frequency was significant(P<0.05). Conclusion The -160 C/A SNP of the CDH1 gene promoter may play an important role in regulating the expression of E-cadherin in hepatocellular carcinoma and the incidence of A allele is associated with down-regulation of E-cadherin expression.
