ABSTRACT
Objective@#To investigate the clinical value of gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery on patients with cholecystolithiasis.@*Methods@#A retrospective study was performed on data of 15 patients with cholecystolithiasis, who underwent gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery from April 2018 to July 2018. The operative data, including situation of operation, operative time, intraoperative hemorrhage, and postoperative complications were recorded.@*Results@#The procedure was performed successfully in all patients with a mean operative time of 108±12 min (ranged from 92-129 min). The intraoperative hemorrhage was 10-30 mL. Eight patients suffered from slight right upper abdominal pain, and 7 patients felt slight pain in umbilical a week after surgery. No fever, incision infection, umbilical hemia, peritonitis, and ascites were reported. The clear-liquid diet was recommended for one day after operation, and postoperative activity was allowed since the second day after operation. All patients were discharged on the fourth or fifth day, and all recovered to their normal life at one week after discharge. Follow-up showed that the scar was small and hidden in umbilical without visible incision after one month. Ultrasonic examination results showed that gallbladder contractile function worked perfectly in four patients and no gallbladder stone was found after three months.@*Conclusion@#Gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery is a safe and effective option for patients with cholecystolithiasis, provides excellent cosmetic outcomes, and can be appropriately carried out under the strict control of surgical indications.

Results The procedure was performed successfully in all patients with a mean operative time of 108±12 min (ranged from 92-129 min). The intraoperative hemorrhage was 10-30 mL. Eight patients suffered from slight right upper abdominal pain,and 7 patients felt slight pain in umbilical a week after surgery. No fever,incision infection,umbilical hemia,peritonitis,and ascites were reported. The clear-liquid diet was recommended for one day after operation,and postoperative activity was allowed since the second day after operation.

ABSTRACT
Objective To discuss effects of different injection methods of nanocarbon tracer on gastrectomy for patients with gastric cancer. Methods Patients, who underwent D2 gastrectomy in Fuzhou General Hospital from January 2014 to December 2015, were randomly divided into group A and group B. The patients in group A were injected with nanocarbon into gastric submucosa of peripheral area of tumor under gastroscope 24 hours before operation. The patients in group B were injected with normal saline firstly, and then injected with nanocarbon. The operations were performed by 5 high qualification physicians and 3 low qualification physicians. The detection of lymph nodes and black stain nodes,detection time,and lymph node metastatic rate were compared between the two groups.Results A total of 248 patients were enrolled in this study,and each group had 124 cases. There was no statistical difference on basic characteristics between the two groups(P>0.05). A total of 2 975 and 3 855 lymph nodes were detected in group A and group B, respectively. The mean number of detected lymph nodes in group A was significantly lower than that of group B(23.9±7.9 VS 31.1±3.6, P=0.00). The rate of black stain nodes in group A was significantly lower than that of group B[71.3%(2 121/2 975)VS 78.1%(3 011/3 855), P= 0.00].There were no statistical differences on lymph node detection time(24.3±5.7 min VS 23.5±6.2 min), tiny lymph node detection rate(33.1% VS 34.9%),and lymph node metastatic rate(27.3% VS 25.8%)between the two groups(P>0.05).In subgroup of low qualification physicians, the number of lymph nodes(16.9± 4.0 VS 30.1±3.7)and the rate of black stain nodes(61.3% VS 77.2%)in group A were significantly lower than those of group B(P<0.05). The corresponding indicators(31.1±3.3 VS 31.5±3.5,76.8% VS 79.0%) had no statistical differences in the subgroup of high qualification physicians(P>0.05). Conclusion For low qualification physicians, injection of normal saline then of nanocarbon into gastric submucosa under gastroscope could improve lymph node and black stain nodes detection rate for patients with gastric cancer on gastrectomy.
