		                        			Objective: To investigate the effect of visceral fat area (VFA) on the surgical efficacy and early postoperative complications of radical gastrectomy for gastric cancer. Methods: A retrospective cohort study method was used. Clinicopathological data and preoperative imaging data of 195 patients who underwent D2 radical gastric cancer surgery at the First Affiliated Hospital of Xi'an Jiaotong University from January 2014 to December 2017 were analyzed retrospectively. Inclusion criteria: (1) complete clinicopathological and imaging data; (2) malignant gastric tumor diagnosed by preoperative pathology, and gastric cancer confirmed by postoperative pathology; (3) no preoperative complications such as bleeding, obstruction or perforation, and no distant metastasis. Those who had a history of abdominal surgery, concurrent malignant tumors, poor basic conditions, emergency surgery, palliative resection, and preoperative neoadjuvant therapy were excluded. The VFA was calculated by software and VFA ≥ 100 cm2 was defined as visceral obesity according to the Japan Obesity Association criteria . The patients were divided into high VFA (VFA-H, VFA≥100 cm2, n=96) group and low VFA (VFA-L, VFA<100 cm2, n=99) group . The clinicopathological characteristics, surgical outcomes and early postoperative complications were compared between the two groups. Univariate and multivariate Logistic regression models were used to analyze the risk factors of early complications. Receiver operating characteristic (ROC) curve was used to analyze predictive values of VFA for early complications. Pearson's χ2 test was used to analyze the correlation between BMI and VFA. Results: There were no significant differences in terms of gender, age, American Society of Anesthesiologists physical status classification, preoperative comorbidities, preoperative anemia, tumor TNM staging, N staging, T staging and tumor differentiation, surgical method, extent of resection, and tumor location between the VFA-L group and the VFA-H group (all P>0.05). However, patients in the VFA-H group had higher BMI, larger tumor, lower rate of hypoalbuminemia and greater subcutaneous fat area (SFA) (all P<0.05). The VFA-H group presented significantly longer operation time and significantly less number of harvested lymph nodes as compared to the VFA-L group (both P<0.05). However, there were no significant differences in intraoperative blood loss, conversion to laparotomy and postoperative hospital stay (all P>0.05). Complications of Clavien-Dindo grade II and above within 30 days after operation were mainly anastomosis-related complications (leakage, bleeding, infection and stricture), intestinal obstruction and incision infection. The VFA-H group had a higher morbidity of early complications compared to the VFA-L group [24.0% (23/96) vs 10.1% (10/99), χ2=6.657, P=0.010], and the rates of anastomotic complications and incision infection were also higher in the VFA group [10.4% (10/96) vs. 3.0% (3/99), χ2=4.274, P=0.039; 7.3% (7/96) vs. 1.0% (1/99), P=0.033]. Multivariate logistic analysis showed that high BMI (OR=3.688, 95%CI: 1.685-8.072, P=0.001) and high VFA (OR=2.526, 95%CI: 1.148-5.559,P=0.021) were independent risk factors for early complications. The area under the ROC curve (AUC) of VFA for predicting early complications was 0.645, which was higher than that of body weight (0.591), BMI (0.624) and SFA (0.626). Correlation analysis indicated that there was a significantly positive correlation between BMI and VFA (r=0.640, P<0.001). Conclusion: VFA ≥ 100 cm2 is an independent risk factor for early complications after radical gastrectomy for gastric cancer.It can better predict the occurrence of above early postoperative complications.

		                        			The study aimed to analyze the clinicopathological features, treatment, and prognosis factors of primary esophageal small-cell carcinoma (PESC). The clinical records and follow-up data of 100 patients with PESC were collected, and the clinicopathological features and treatments were examined. Log-rank test and Cox regression model were performed to identify the independent prognostic factors. Progressive dysphagia, weight loss, and abdominal pain were the most common initial symptoms in the 100 patients with PESC. The primary tumor site mainly occurred in the middle of the chest (51%, 51/100), and the ulcer type was the most common under gastroscope (31%, 31/100). One or more positive markers of epithelial origin were present in all of the enrolled patients. At the time of diagnosis, 80 cases had limited disease (LD) and 20 cases had extensive disease (ED). The 1-, 3-, and 5-year survival rates of PESC patients were 57.0%, 18.0%, and 11.0%, respectively, with a median survival time (MST) of 13.8 months. In all PESC patients, multivariate Cox regression analysis indicated that the significant prognostic factors included the lesion length (=2.661, <0.001), TNM staging (=1.464, =0.016), and treatment methods (=0.333, <0.001). Besides, in patients with LD, the lesion length (=2.638, =0.001) and treatment methods (=0.285, <0.001) were independent prognostic factors. The MST of patients in surgery + chemotherapy group (21.6 months) was longer than that of the surgery only group (8.3 months, =0.021), while patients in surgery+ chemotherapy+ radiotherapy group were also associated with a longer MST than the chemotherapy + radiotherapy group (31.0 months, 9.8 months, respectively; <0.001). PESC is a rare esophageal malignant tumor with poor prognosis. Our findings reveal that the lesion length, TNM staging, and treatment method are independent prognostic factors for PESC patients. Moreover, surgery-based comprehensive treatments may prolong the survival of patients with LD.

		                        			A 54-year-old female with postprandial dyspepsia and abdominal pain was diagnosed as locally advanced unresectable intrahepatic cholangiocarcinoma by radiologic imaging studies resulting in invasion to bilateral main bile duct and right portal vein. The patient underwent extended right hepatectomy and portal vein resection after gemcitabine and cisplatin combined chemotherapy for a total of 40 cycles after the diagnosis. Final pathology showed, followed by pathological complete remission, without any residual cancer cell. The patient has survived for over 6 years without any evidence of recurrence. This case suggests that locally advanced intrahepatic cholangiocarcinoma, which can't be resected, was also proved to be capable of pathological complete remission with active chemotherapy, and long-term survival could be achieved. Therefore, active multidisciplinary approach and patient-oriented treatments using various methods should be considered for locally advanced unresectable intrahepatic cholangiocarcinoma.

OBJECTIVETo assess the clinical value of the diagnostic laparoscopy in choosing treatment strategies for patients with gastric cancer.
METHODSRetrospective analysis was performed on clinical and pathological data collected from 2 023 patients undergoing gastric cancer surgery in the Zhongshan Hospital of Fudan University from 2009 to 2014. All the patients were diagnosed as gastric cancer by endoscopic biopsy and staged by imaging examination before surgery. During the diagnostic laparoscopy procedure, a small periumbilical incision was made and a pneumoperitoneum with COunder 10-15 mmHg was established through a port. A 10 mm trocar was put in, and the camera was inserted. Two 5 mm trocars were put in two ports which located in midclavicular line two fingers under the left and right costal margin and then the instruments were inserted. A thorough inspection included ascites, the abdominal cavity, liver, diaphragm, spleen, greater omentum, colon, small intestine, mesentery, adnexa (female) and pelvic floor. If the tumor located at the posterior part of the stomach, the gastrocolic ligament was opened in order to look for carcinomatosis in the omental bursa. The accuracy rate of diagnostic laparoscopy in diagnosing adjacent organ invasion and intra-abdominal metastasis was calculated, and the rate of adjusting treatment plans after diagnostic laparoscopy was also calculated.
RESULTSThere were 52.7%(1 067/2 023) of patients underwent diagnostic laparoscopy. The accuracy rate of diagnostic laparoscopy in evaluating adjacent organ invasion and intra-abdominal metastasis were 98.3%(1 049/1 067) and 98.1%(1 047/1 067) respectively. Besides, 14 patients with stage T4b and 32 with intra-abdominal metastasis, which were missed by imaging examination, were diagnosed by diagnostic laparoscopy. The treatment plans of 9.3% (99/1 067) of patients were changed after diagnostic laparoscopy, and 65 (6.1%) cases of non-therapeutic laparotomy were avoided. However, 18 cases of adjacent organ invasion and 20 cases of intra-abdominal metastasis were still missed by diagnostic laparoscopy, and 12 cases received non-therapeutic laparotomy.
CONCLUSIONDiagnostic laparoscopy has considerable value in assessing adjacent organ invasion and intra-abdominal metastasis and has great clinical significance in making precise treatment plans.

OBJECTIVETo explore the correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of Chinese medicine (CM) in colorectal cancer patients.
METHODSTotally 112 colorectal cancer patients undergoing open abdominal surgery or laporoscopic surgery were syndrome typed as five types, i.e., inner-accumulation of damp and heat, blockage of stasis and toxin, Pi-Shen yang deficiency, blood-qi deficiency, Gan-Shen yin deficiency. Signs of living body in abdominal and pelvic cavities were collected. The correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of CM were analyzed.
RESULTSRed colorectal canals or mass were dominated in colorectal cancer patients with inner-accumulation of damp and heat syndrome. Dark purple colorectal canals or mass were dominated in colorectal cancer patients with blockage of stasis and toxin syndrome. Reddish colorectal canals or mass were dominated in colorectal cancer patients with blood-qi deficiency syndrome. Pale colorectal canals or mass were dominated in colorectal cancer patients with Pi-Shen yang deficiency syndrome. Whitish or red-white stripes were dominated in colorectal cancer patients with Gan-Shen yin deficiency syndrome. Dropsy colorectal canal was associated with Pi-Shen yang deficiency syndrome. Intracavitary effusion was often seen in colorectal cancer patients with inner-accumulation of damp and heat syndrome. The effusion was yellowish in less amount. Intracavitary adhesion was often seen in colorectal cancer patients with blockage of stasis and toxin syndrome. There was no correlation between the maximum diameter of mass or each syndrome type of CM.
CONCLUSIONThere existed correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of CM, which could be taken as one of references for syndrome typing of colorectal cancer patients.

		                        			Xanthogranulomatous inflammation (XGI) is characterized histologically by the deposition of foamy macrophages and infiltration of inflammatory cells. While XGI is extremely rare, it has been reported in the gallbladder, kidney, stomach, and lymph nodes. A 61-year-old woman presented with epigastric pain for 2 weeks. Abdominal computed tomography and magnetic resonance imaging showed a pancreatic head mass with distal common bile duct wall thickening. Endoscopic ultrasonography followed by fine needle aspiration was performed, and subsequent pathology report revealed a benign disease. Because uncontrolled abdominal pain persisted and possibility of malignancy could not be excluded, Whipple's operation was eventually performed, and pathology report showed xanthogranulomatous pancreatitis (XGP). Herein, we report a case of symptomatic XGP mimicking of pancreas cancer. Although XGP is extremely rare, it should be considered as a differential diagnosis of neoplastic lesions of the pancreas.

		                        			OBJECTIVE: In this study we utilized the Surveillance, Epidemiology and End-Results (SEER) registry to identify risk factors for lymphatic spread and determine the incidence of pelvic and para-aortic lymph node metastases in patients with uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) who underwent complete surgical staging and lymph node dissection. METHODS: Nine hundred seventy-two eligible patients diagnosed between 1998 to 2009 with International Federation of Gynecology and Obstetrics (FIGO) 1988 stage IA-IVA UPSC (n=685) or UCCC (n=287) were identified for analysis. Binomial logistic regression was used to determine risk factors for lymph node metastasis, with the incidence of pelvic and para-aortic lymph node metastases reported for each FIGO primary tumor stage. The Cox proportional hazards regression model was used to determine factors associated with overall survival. RESULTS: FIGO primary tumor stage was the only independent risk factor for lymph node metastasis (p<0.01). The incidence of pelvis-only and para-aortic lymph node involvement according to the FIGO primary tumor stage were as follows: IA (2.3%/3.8%), IB (7.5%/5.2%), IC (22.5%/16.9%), IIA (20.8%/13.2%), IIB (25.7%/14.9%), and III/IV (25.7%/24.3%). Prognostic factors for overall survival included lymph node involvement (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.09 to 1.85; p<0.01), patient age >60 years (HR, 1.70; 95% CI, 1.21 to 2.41; p<0.01), and advanced FIGO primary tumor stage (p<0.01). Tumor grade, histologic subtype, and patient race did not predict for either lymph node metastasis or overall survival. CONCLUSION: There is a high incidence of both pelvic and para-aortic lymph node metastases for FIGO stages IC and above uterine papillary serous and clear cell carcinomas, suggesting a potential role for lymph node-directed therapy for these patients.

		                        			OBJECTIVE: The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI). MATERIALS AND METHODS: Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist. IFs were classified according to organ or system (liver, gallbladder, kidney, bladder, uterus, ovary, lymph node, intestine and aorta). The rate of reporting of a range of IF was examined. The outcome of each patient's treatment was evaluated based on review of hospital records and by telephone interviews. RESULTS: A total of 253 IFs were found in 241 patients (18.8% of 1278). Among these, clinically significant IFs (n = 34) included: 2 renal masses (0.15%), 2 aortic aneurysms (0.15%), 2 cases of hydronephrosis (0.15%), 11 adrenal masses (0.86%), 7 lymphadenopathies (0.55%), 6 cases of endometrial or cervical thickening (0.47%), 1 liver hemangioma (0.08%), 1 pelvic fluid (0.08%) and 2 ovarian dermoid cysts (0.15%). Overall, 28% (71/253) of IFs were included in the clinical reports, while clinically significant findings were reported in 41% (14/34) of cases. CONCLUSION: Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant. However, IFs including clinically important findings are occasionally omitted from formal radiological reports.

OBJECTIVETo explore the patterns and influencing factors of lymph node metastasis in limited esophageal small cell carcinoma (PESCC).
METHODSA total of 98 limited stage PESCC patients who underwent surgery were selected for this study. The lymph node metastasis ratio at different sites, depth of invasion, tumor length and other factors were analyzed to assess their influence on lymph node metastasis.
RESULTSAmong the 98 PESCC cases, 46 cases had lymph node metastasis (46.9%). 100 out of 833 lymph nodes had metastasis, with a metastasis ratio of 12.0%. For upper thoracic esophageal small cell carcinomas, lymph node metastasis ratios were 42.9%, 12.5%, 0 and 0 in the superior mediastinum, middle mediastinum, inferior mediastinum and abdominal cavity, respectively. In the middle thoracic PESCCs, the lymph node metastasis ratios were 18.8%, 7.7%, 15.7%, and 15.3%, respectively. In the lower thoracic PESCCs, the lymph node metastasis ratios were 0, 0, 27.3% and 23.5%, respectively. Lymph node metastasis rates in PESCCs at stages T1, T2, T3, T4 were 15.4%, 42.3%, 63.9%, and 80.0%, respectively. The lymph node metastasis ratios in PESCCs at stages T1, T2, T3, T4 were 2.0%, 8.3%, 17.8% and 25.0%, respectively. Lymph node metastasis rate and lymph node metastasis ratio at different T stages were of significant difference (P<0.05 for all). Lymph node metastasis rates in patients with tumor <3 cm, 3-5 cm, and >5 cm were 30.6%, 46.9% and 66.7%, respectively, and lymph node metastasis ratios were 5.4%, 11.0% and 21.1%, respectively. Lymph node metastasis rate and lymph node metastasis ratio in patients with different tumor length had significant differences (P<0.05 for all). Lymph node metastasis ratio was 11.6% in the Chr-A negative and weak positive group, much higher than 4.3% in the Chr-A positive group (P=0.013). There was a tendency that lymph node metastasis ratio of NSE-positive group was higher than that of NSE-negative and weak positive group (P=0.069). The logistic univariate analysis did not find high risk factors of distant lymph node metastasis (all P>0.05). Logistic multivariate analysis found that only depth of invasion was a risk factor of lymph node metastasis in limited PESCC (P=0.002).
CONCLUSIONSEsophagus small cell carcinomas sometimes have early lymph node metastases in many sites and distant range. The middle thoracic PESCCs tend to have extensive metastasis quite common in the upper mediastinal lymph nodes. Lower mediastinal and abdominal lymph node metastases are often seen in lower thoracic PESCCs. The depth of invasion and tumor length are main factors influencing mediastinal lymph node metastasis. The depth of invasion is an independent risk factor for lymph node metastasis.

OBJECTIVETo analyze the pattern and the clinicopathologic risk factors of lymph node metastasis (LNM) in pN1 stage esophageal squamous cell carcinoma.
METHODSClinical data of 181 patients (154 male and 27 female patients, aging from 38 to 84 years) who underwent esophagectomy during January 2005 and December 2008 were reviewed, including 69 cases through left thoracotomy and 112 cases through right thoracotomy. All patients underwent systematic lymphadenectomy. The risk factors related to lymph node metastasis were analyzed by χ² test and Logistic regression analysis.
RESULTSThe relatively highest LNM site were middle and lower thoracic paraesophageal (38.4%), right and left cardiac (35.3%) and the left gastric artery (38.8%). The LNM of middle and lower thoracic paraesophageal was correlated with T stage (χ² =11.754, P=0.009). A correlation was also found among the LNM of upper mediastinum and the location of tumor (P=0.039). The T stage (χ² =8.694, P=0.034) and TNM stage (χ² =6.906, P=0.032) were the risk factors of the LNM of middle and lower mediastinum. The risk factors of the LNM of abdomen were the location of tumor, the length of tumor, T stage and TNM stage (χ² =5.713 to 16.749, P>0.05). Multivariate analysis showed that the location of tumor is the independent risk factors for the abdominal lymph node metastasis.
CONCLUSIONSThe relatively highest LNM sites are correlated with the location of tumor, T stage, the length of tumor and TNM stage. According to the risk factors of LNM, the relatively highest LNM sites should be mainly swept.
