ABSTRACT
Objective:To compare Da-vinci robotic surgical system with laparoscopic surgery for the repair of hiatal hernia.Methods:The clinical data of 115 patients undergoing minimally invasive Nissen fundoplication at the Department of Hernia and Abdominal Wall Surgery, the Affiliated Hospital,Xuzhou Medical University from Dec 2019 to May 2022 were retrospectively studied. After propensity score matching (PSM), 46 cases in each group were included:Robot-assisted surgery (RS group) and laparoscopic surgery (LS group). Postoperative complications were collected and GERD Questionnaire (GERDQ) were used as the standard in evaluation of the results.Results:Patients in RS group had less intraoperative bleeding ( P<0.001), shorter postoperative gastrointestinal recovery time ( P<0.001), and shorter postoperative hospital stay ( P=0.002). The LS group had a shorter operative time ( P<0.001) and lower total hospital cost ( P<0.001). GERD-Q scores decreased significantly in both groups at 3 and 6 months postoperatively compared with preoperative scores ( P<0.001). There was no statistically significant difference between the two groups in the incidence of postoperative complications ( P>0.05). No recurrence was seen in both groups during postoperative follow-up. Conclusion:Da-vinci robot-assisted repair of hiatal hernia is as safe and feasible as laparoscopic procedures, with less intraoperative trauma and quicker, earlier recovery.
ABSTRACT
Objective:To study the use of the da Vinci robot in distal pancreatectomy.Methods:The data of 53 patients who underwent minimally invasive distal pancreatectomy at the Department of General Surgery of the Affiliated Hospital of Xuzhou Medical University from February 2017 to March 2022 were retrospectively analysed. There were 16 males and 37 females, aged (48.2±16.9) years. These patients were divided into the robot assisted pancreatectomy group (the robot group, n=18) and the laparoscopic pancreatectomy group (the laparoscopic group, n=35) based on the surgical treatment methods. The operations were performed by the same team of surgeons. All patients were diagnosed to have benign or borderline malignant tumors of body and tail of pancreas by preoperative examinations. The success rate of spleen preservation distal pancreatectomy, operation time, intraoperative bleeding, and postoperative complications (including pancreatic fistula, postoperative bleeding, abdominal infection) were compared between the two groups. Results:Spleen preserving distal pancreatectomy was successfully carried out in 13 patients (72.2%) in the robot group and 15 patients (42.9%) in the laparoscopic group. The rate of spleen preservation in the robot group was significantly higher than that in the laparoscopic group (χ 2=4.11, P=0.043). Intraoperative blood loss (104.4±69.3) ml and time to first postoperative passage of flatus were (3.7±1.0) d in the robot group were significantly better than the laparoscopic group (199.4±102.9) ml and (4.8±1.3) d, respectively (both P<0.05). The total incidence of complications in the robot group was 7 cases (38.9%), compared with 14 cases (40.0%) in the laparoscopic group, with no significant difference between the two groups(χ 2=0.006, P=0.938). Conclusions:Robotic-assisted distal pancreatectomy was safe and feasible, and it had advantages in resulting in better spleen preservation than laparoscopic distal pancreatectomy.
ABSTRACT
Objective:To find out whether surgeon's proficiency in laparoscopic gastrectomy helps to get over the learning curve of laparoscopic pancreaticoduodenectomy (LPD) more quickly.Methods:From January 2015 to October 2016, the clinical and perioperative data of 41 consecutive patients who underwent LPD at the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. The learning curves were evaluated using the CUSUMOT method and RA-CUSUM method.Results:Of 41 patients, 25 were males and 16 were females, with age ranging from 25.0 to 83.0 (60.6±13.7) years. These patients all successfully underwent LPD, with operation time Mean±SD being (456.3±85.9) min. There were 4 patients (9.8%) who developed biochemical fistula and 4 patients (9.8%) grade B pancreatic fistula. There was no grade C pancreatic fistula after operation. There were 10 patients who developed postoperative complications ≥ Clavien-Dindo grade III (24.39%) and 1 died. The data of the CUSUMOT method showed the learning curve to be over after the 33rd patient and the data of the RA-CUSUM method showed the learning curve to be over after the 31st patient.Conclusions:Laparoscopic gastrectomy helped surgeons to master the key techniques in LPD faster, and to get over the learning curve more safely and quickly.
ABSTRACT
Objective To evaluate the result of laparoscopic pancreaticoduodenectomy (LPD).Methods We retrospectively analyzed the perioperative clinical data of 111 consecutive LPD procedures performed from Jan 2015 to Aug 2018 at Department of General Surgery,the Affiliated Hospital of Xuzhou Medical University.Results Of the 111 patients undergoing laparoscopic procedure,24 patients (21.6％) had abdominal surgery history.The mean operative time was (360.9 ± 108.9)minutes.The mean blood loss was (270.9 ± 184.9)m1.The mean operative time of pancreatojejunostomy and choledochojejunostomy was (46.2 ± 11.6) minutes and (19.0±7.2) minutes,respectively.The mean postoperative hospital stay was (14.9 ± 4.7) days.The rate of pancreatic fistula grade B was 6.3％ and pancreatic fistula grade A was 20.7％.The rate of bile leakage was 1.8％.Second surgical operation was necessary for 5 cases (4.5％),delayed postoperative hemorrhage occurred in 2 cases (1.8％).The mean number of lymph nodes harvested was(14.2 ± 7.9) and the positive rate number was (0.9 ± 1.8).Conclusions LPD improves the operation quality,reduces intraoperative hemorrhage and accelerates the postoperative recovery.
