Objective To compare the efficacy of incision healing by abdominal wall closure measure without suturing subcutaneous fat layer and the traditional abdominal wall closure measure. Methods Four hundreds patients underwent operation of abdominal median incision and abdominal paramedian incision from Sep. 2010 to Sep. 2012 in our department were randomly assigned to observation group （n=199） and control group （n=201）. The patients in obser- vation group underwent abdominal wall closure measure without suturing subcutaneous fat layer， and those of control group were subjected to abdominal wall closure by traditional layer suture technique. Comparison of efficacy of incision healing in the 2 groups was performed. Results The incidences of fat liquefication 〔1 （0.5%） vs.18 （9.0%）〕， incision swelling 〔3 （1.5%） vs.16 （8.0%）〕， incision induration 〔1 （0.5%） vs.15 （7.5%）〕， and dehiscence of wound 〔0 （0） vs.9 （4.5%）〕 in observation group were significantly lower than those of control group （P＜0.01）， but there was no significant difference in incidence of subcutaneous hematoma 〔2 （1.0%） vs.0 （0）， P＞0.05〕. The rate of primary healing in obser-vation group was significantly higher than those of control group 〔199 （100%） vs.186 （92.5%）， P＜0.01〕. Duration of abdominal closure 〔（13.0±1.6） min vs.（18.0±2.2） min〕 and postoperative hospital stay 〔（7.7±1.3） days vs.（9.6±1.9） days〕 were all shorter than those of control group （P＜0.01）. Conclusion The abdominal wall closure measure without suturing subcutaneous fat layer is obviously more effective to the traditional layer suture technique， which is a suture way worthy to spread.
Objective To assess the efficiency of Kansui root in the treatment of patients with severe acute pancreatitis. Methods Trials were identified by searching CNKI, VIP, CBM, PubMed, EMbase, and The Cochrane Library. Randomized controlled trials ( RCTs) and quasi-randomized controlled trials (quasi-RCT) were included. Two reviewers assessed the quality of each study and extracted data independently. Statistical analysis was performed by using RevMan 4.2.7. Results Finally, four trials involving 240 patients were included. All included trials were quasi-RCT. Meta-analysis showed that the Kansui group had the tendency of reducing early deaths [RR=0.45, 95%CI(0.23, 0.89)], shortening the course of treatment, reducing the incidence of hyperamylasemia, and reducing the mean hospitalization stay. Moreover, the duration of abdominal pain and distension were shortened, and conversion to operation rate and incidence of complications of SAP were reduced significantly compared with the control group. Conclusion There was not enough evidence to support the Kansui root’s effectiveness present since the included trials are of poor quality. Therefore, large-scale high-quality RCTs are needed.
Objective To improve the vigilance and awareness of malignancy presenting as dermatosis and reduce misdiagnosis. Methods Two cases of gastric cancer presenting as dermatomyositis and erythroderma respectively in the last two years were retrospectively analyzed and the relevant literatures were reviewed. Results The two patients were admitted to hospital due to skin diseases， diagnosis of gastric cancer through endoscopy， and proved to be gastric cancer associated with dermatosis by pathological examination after surgical resection. Conclusions Paraneoplastic dermatoses can be seen as an early manifestation of the internal malignancy. The patients with paraneoplastic dermatoses should be excluded visceral tumors by the means of biomarkers， endoscopy， PET/CT， and so on.
Objective To discuss the effectiveness of intramedullary nail fixation with selective cable wiring in the treatment of ipsilateral femoral neck fracture and subtrochanteric fracture. Methods Between June 2012 and December 2015, a total of 19 patients with ipsilateral femoral neck fracture and subtrochanteric fracture underwent closed reduction of femoral neck fracture and intramedullary nail fixation combined with selective cable wiring. There were 5 males and 14 females with a median age of 52 years (range, 35-77 years). The cause of injury included traffic accident injury in 17 cases and falling injury in 2 cases. According to Garden classification for femoral neck fractures, 7 cases were rated as type Ⅱ, 8 as type Ⅲ, and 4 as type Ⅳ. Femoral subtrochanteric fractures were classified by Seinsheimer classification, with 9 cases as type Ⅱ, 5 as type Ⅲ, 3 as type Ⅳ, and 2 as type V. The interval from injury to operation ranged from 2 to 7 days with an average of 3.7 days. Results The operation time was 58-125 minutes (mean, 82.4 minutes) and the intraoperative blood loss was 225-725 mL (mean, 289.5 mL). All incisions achieved healing by first intention and no early complication such as infection was observed. All patients were followed up 12-18 months (mean, 13.9 months). At 1 month after operation, the tip apex distance was 9-23 mm (mean, 15.2 mm). All patients achieved bone union with the healing time of 18-42 weeks (mean, 27.4 weeks). One case of hip varus and femoral neck re-displacement (femoral neck shaft angle was 122°) occurred at 3 months after operation, which achieved bone union at 42 weeks after operation. Five patients complained of postoperative pain with the visual analogue scale (VAS) score of 1-3 (mean, 1.8), which did not influence normal life. A total of 16 patients recovered preoperative hip function. During follow-up, no fracture nonunion, femoral head necrosis, implant failure, screw cut-out, and loosening of cable wiring was observed. The Harris hip score (HSS) was 72-92 (mean, 82.8) at last follow-up and 15 patients (78.9%) achieved good hip function. Conclusion Intramedullary nail fixation combined with selective cable wiring was effective in the treatment of ipsilateral femoral neck fracture and subtrochanteric fracture.
Objective To explore predictive value of radiological indexes for hemorrhage in patients with portal hypertension. Methods The clinical data and radiological data of patients with portal hypertension accompanied with hepatitis B from June 2008 to June 2014 in the Nanjing Drum Tower Hospital were analyzed retrospectively. Patients with hepatocellular carcinoma, portal vein thrombosis, or portal hypertension due to other causes, such as autoimmune hepatitis, pancreatitis, or hematological diseases were excluded. Results Ninety-eight patients were studied and subsequently divided into a hemorrhage group (n=57) and a non-hemorrhage group (n=41). There were no statistical differences in the clinical indexes such as the age, prothrombin time, serum albumin, serum creatinine, serum sodium, white blood cell count, and blood platelet count (P>0.05). However, the differences were statistically significant in the serum total bilirubin, hemoglobin, and liver function with theP values of 0.023, 0.000, and 0.039, respectively. For the radiological indexes, the hemorrhage was correlated with the diameter of posterior gastric vein (P=0.028 3) or grading of esophageal varices (P=0.022 1). Logistic procedure was used to construct the model with stepwise selection and finally the diameter of inferior mesenteric vein, diameter of posterior gastric vein, grading of esophageal varices, and diameter of short gastric vein were enrolled into this model. These indexes were scored, the risk of bleeding increased with increasing the points. Then the model was validated with 26 patients with portal hypertension from July 2014 to December 2014, the area under the receiver operating characteristic curve was 0.884 9 by this radiological model. Conclusions A radiological scoring model is constructed including diameter of inferior mesenteric vein, grading of esophageal varices, diameter of posterior gastric vein, and diameter of short gastric vein, which might predict risk of hemorrhage in patients with portal hypertension. However, further protective study of large sample is needed to validate this model.
