ABSTRACT
Objective:To explore the relationship between body mass index (BMI) and clinicopathological features and prognosis of gallbladder cancer.Methods:The clinical and follow-up data of three hundred and eighty-six patients of gallbladder carcinoma were retrospectively, who were treated from January 2008 to December 2013 in the Department of Hepatobiliary Surgery, Eastern Hepatobiliary Hospital, Second Military Medical University. According to the guidelines for prevention and control of overweight and obesity in Chinese adults, the patients were divided into three groups: normal weight group(BMI<23.5 kg/m 2, 239 cases, accounting for 61.9%), overweight group (23.5 kg/m 2≤BMI<27.5 kg/m 2, 127 cases, accounting for 32.9%) and obesity group(BMI≥27.5 kg/m 2, 20 cases, accounting for 5.18%). The clinicopathological factors(gender, age, diabetes mellitus, hypertension, gallbladder related diseases, jaundice, tumor location, TMN, postoperative days, tissue differentiation, liver invasion, intraoperative blood transfusion, complications) of the three groups were compared, and the relationship between BMI and 5-year survival rate was analyzed. Measurement data with normal distribution were indicated as mean±standard deviation( Mean± SD), measurement data with skewed distribution were represented as M( P25, P75). Nonparametric rank sum test was used for measurement data. Categorical variables were compared by the chi-square test or Fisher probability method. The survival curve was drawn by the Kaplan-Meier method. The univariate analysis and multivariate analysis of prognosis were respectively done using the Log-rank test and COX regression model. Results:The median survival time of 386 patients with gallbladder cancer was 12.1 months. The overall survival rates of 1, 3 and 5 years were 51.8%, 25.2% and 16.8%, respectively. Univariate survival analysis showed that age, jaundice, accidental gallbladder cancer, tumor location, TMN, surgical method, tissue differentiation, liver invasion, intraoperative blood transfusion, and complications affected the 5-year survival rate ( χ2=12.24, 30.87, 37.01, 7.92, 104.23, 118.76, 12.05, 49.12, 6.85, 12.24, P<0.05). BMI was related to hypertension, but it had no significant effect on the 5-year survival rate. However, with the increase of BMI, the 5-year survival rate increased (16.3% vs 16.7% vs 23.3%, P=0.774). Multivariate survival analysis showed that surgical method( OR=1.441, 95% CI: 1.219-1.705), liver invasion( OR=1.625, 95% CI: 1.264-2.091), M stage( OR=1.664, 95% CI: 1.070-2.587), and N stage( OR=1.511, 95% CI: 1.218-1.875) were independent risk factors for prognosis in this group of patients ( P<0.05), and BMI was not an independent risk factor ( P=0.901). Conclusions:BMI has no significant effect on the prognosis of patients with gallbladder cancer. Obese patients with gallbladder cancer do not need to wait for weight loss before surgery.
ABSTRACT
Acute abdomen is a common clinical disease and frequently-occurring disease. It has the characteristics of acute onset, rapid progress and many changes in clinical manifestations. It often involves multiple systems in treatment, and often requires multidisciplinary cooperation in diagnosis and treatment. As a first-line doctor, it is not easy to quickly diagnose and make correct decisions. Once it is handled improperly, it can lead to serious consequences. Although there are many related articles on the diagnosis and treatment of acute abdomen, with the continuous development of clinical diagnosis and treatment methods, it is still necessary to update the emergency diagnosis and treatment skills of acute abdomen. This article introduces the classification, characteristics, diagnosis, treatment of acute abdomen both inthe common population and special population, and hopes to cultivate the clinical diagnosis and treatment thinking of young doctors.

ABSTRACT
Objective To explore the application value of three-dimensional (3D) visualization combined with portal vein (PV) arterialization technologies in pancreaticoduodenectomy.Methods The retrospective descriptive study was adopted.The clinical data of 1 patient with duodenal cancer who was admitted to the Chenggong Hospital of Xiamen University in August 2015 were collected.The preoperative plain scan images in the upper abdomen and enhanced scan images in the arterial and PV phases using 320-slice spiral CT were converted to the 3D images by 3D visualization technology.The 3D data were used for detecting tumor invading pancreatic head and organizational structure surrounding hepatic hilus,and making a preliminary surgical plan.Open exploration found that tumor involved pancreatic head and didn't invade superior mesenteric artery and vein,and then pancreaticoduodenectomy was applied to the patient during operation.Intraoperative proper hepatic artery-PV end-to-side anastomosis was used for increasing R0 resection rate.Operation time,volume of intraoperative blood loss,result of postoperative pathological examination,liver function and complication and vascular patency at postoperative week 1 and vascular patency at postoperative month 1 were observed.The patient underwent color Doppler ultrasound and digital subtraction angiography (DSA) at postoperative month 1 in order to detect blood vessels,and was followed up by outpatient examination for observing tumor till November 2015.Results There was a clear and solid 3D reconstruction model between anatomical position of tumor and blood vessels,and preoperative assessment was consistent with intraoperative finding.Operation time and volume of intraoperative blood loss were 6.5 hours and about 1 500 mL.The patient was confirmed as intestinal diffuse large B-cell lymphoma by postoperative pathological examination.The patient had normal liver function at postoperative week 1 and discharged from hospital at postoperative week 2,without abdominal secondary hemorrhage,infection,pancreatic fistula,intestinal fistula and other severe complications.PV blood flowing was normal by color Doppler ultrasonography at postoperative week 1 and month 1.DSA examination showed that there was no proper hepatic artery images and visible compensatory liver artery at postoperative month 1.During follow-up,no tumor recurrence was detected.Conclusion 3D reconstruction model can provide an accurate preoperative assessment,and PV arterialization technology for unreserved hepatic artery has a certain degree of clinical value in pancreaticoduodenectomy.
