ABSTRACT
Objective To explore the clinical safety and validity of Da Vinci surgical system in distal pancreatic tumor resection.Methods The clinical data of 14 patients with distal pancreatic tumor underwent robotic surgeries by using Da Vinci surgical system from January 2009 to June 2012 were retrospectively analyzed.Results The average operation time was 343.93 (170-575) min,average blood loss was 192.5 (10-700) ml,without blood trahsfusion.Pathologic examination showed:pancreatic ductal adenocarcinoma in 7 patients,pancreatic cystadenoma in 1 patient,mucous cystadenoma in 1 patient,cystadenocarcinoma in 1 patient,high levels of pancreatic ductal intraepithelial neoplasia in 1 patient,insulinoma in 1 patient,solid pseudo-papillary tumor in 2 patients.Two patients with pancreatic leaks after operation and then relieved after conservative medical therapy.Others were discharged from hospital without complications.The average hospital stay was 10.64 d.Conclusions Da Vinci surgical system is safe and effective in treatment for patients with distal pancreatic rumor with minimally invasive advantage.Because lack of surgical experience and small sample,a large sample with long term follow-up of high-quality clinical research is required and then update the system to evaluate the efficacy and safety.
ABSTRACT
ObjectiveTo explore the value of expanded radical resection for gallbladder cancer located respectively at body and bottom of the gallbladder and at the neck.MethodsIn this study,91 cases of gallbladder cancer were macropathologically divided into two groups, one with the lesion at the body and bottom of the gallbladder and the other at the neck, survival analysis was made accordingly. Three different kinds of resection were performed: the expanded radical resection, the standard radical resection and palliative operation.ResultsThe overall median survival rate of patients undergoing expanded radical operation was significantly longer than that of the cases doing other two procedures, that was 27. 1 ± 2. 4,10. 7 ±2. 2,4. 7 ±2.2 (months) respectively for body and bottom cancer, and 8.5 ±2. 1,6. 7 ± 1.9,3.1 ± 1.1 (months) respectively for neck cancer. For cancer at the body and bottom RO was achieved by expanded radical resection in 16/18(88％ ) cases and by standard radical resection in 7/12(58％ ) cases, while for cancer at the neck it was in 6/16(38％ ) cases, and in 3/13 (23％)cases only.ConclusionsThe median survival time is longer and RO resection rate is higher in patients with the cancer at the body and bottom than these at the neck of the gallbladder.
ABSTRACT
Objective To summarize the clinical experience in Da Vinci surgical system-assisted hepatopancreatobiliary surgery.Methods From January to December in 2009,94 patients with hepatopancreatobiliary diseases were treated at General Hospital of Second Artillery of PLA.The surgical procedure and postoperative recovery of patients were analysed.Results A total of 90 patients had successfully undergone robotic surgery,and 4 patients were converted to open surgery with the conversion rate of 4%(4/94).Sixteen patients received surgeries for hepatic diseases,and 1 patient with a giant hemangioma in the right posterior hepatic lobe was converted to open surgery,because a very close relationship between the hemangioma and inferior vena cava was observed;27 patients received surgeries for hilar diseases;19 patients underwent surgeries for pancreatic diseases,and 3 patients were converted to open surgery,including 2 with poor exposure of the giant pancreatic head carcinoma and 1 with tumors in the distal common bile duct:32 patients received other surgeries,including 6 with choledochojejunostomy and 11 with laparoscopic common bile duct exploration.Conclusions Almost all kinds of operations for hepatopanereatobiliary diseases could be performed by Da Vinci surgical system.Da Vinci surgical system expands the indications for laparoscopic surgery.
ABSTRACT
Objective To summarize the clinical experience of operations with Da Vinci surgical system in 27 patients with previous abdominal surgery.Methods The clinical data of 27 patients with previous abdominal surgery who had received reoperation using Da Vinci surgical system at General Hospital of Second Artillery of PLA from January to December 2009 were retrospectively analysed.The distribution of trocars was designed according to the surgical sites and previous surgical incision sites.The operation was divided into 2 steps:firstly,intraabdominal adhesion was dissected and the robotic arms were set up;secondly,the lesions were resected.Experience in trocars placement,surgical approach and management of complications were summarized.Results Six approaches were designed according to previous incision sites.Of all patients,22 were with severe intraabdominal and hepatic hilar band adhesion,and 5 with strip adhesion.One patient who underwent intraabdominal radiotherapy and chemotherapy abandoned robotic surgery because of the failure in trocar placement and pneumoperitoneum establishment.Twenty-six patients had successfully undergone robotic surgery and the success rate was 96%(26/27).Of the 26 patients,1 was complicated with enterorrhexis intraoperatively and received repairment.No postoperative complication was observed.Conclusions Previous abdominal surgery has little influence on robotic surgery with Da Vinci system. Pneumoperitoneum establishment,insertion point of the first trocar and dissection of the intraabdominal adhesions are key points for success of operation.
ABSTRACT
objective To summarize the clinical experience of pancreatoduodenectomy using Da Vinci surgical system,and to investigate the methods to improve its efficacy.Methods Sixteen patients who received pancreatoduodenectomy from January to December 2009 at the General Hospital of Second Artillery of PLA were divided into robotic group(n=8)and open group(n=8).Data on the surgical procedure,perioperative management and postoperative recovery between the 2 groups were retrospectively analysed using t test and chi-square test.Result The radical resection rates of robotic group and open group were 7/8 and 8/8,respectively,with no significant difference between the 2 groups(χ~2=1.067,P＞0.05).The operation time of robotic group was (718±186)minutes,which was significantly longer than(420±127)minutes of open group(t=3.714,P＜0.05＝.The blood loss of robotic group was(153±43)ml,which was significantly less than(210±53)ml of open group(t=2.318,P＜0.05＝.The postoperative ambulation time and length of hospital stay of robotic group were(28±7)hours and(16±4)days,which were significantly shorter than(96±18)hours and(24±7)days of open group(t=9.939,2.714,P＜0.05＝.The incidences of postoperative complications of robotic group and open group were 2/8 and 6/8,respectively,with significant difference between the 2 groups(χ~2=6.349,P＜0.05＝.The incidences of anastomotic leakage of robotic group and open group were 2/8 and 3/8,respectively,with no significant difference between the 2 groups(χ~2=0.291,P＞0.05).Conclusion Pancreatoduodenectomy performed by Da Vinci surgical system is feasible and safe,and with the advantages of less trauma and rapid recovery of patients.
