ABSTRACT
Pancreaticoduodenectomy is one of the most difficult abdominal operations, and the difficulty in resection and complicated digestive tract reconstruction have brought great challenges for surgeons. At present, laparoscopic pancreaticoduodenectomy has been widely used in clinical practice, and compared with traditional 2D laparoscopy, 3D laparoscopy has the features of high magnification, high definition, and three-dimensional vision, which enables surgeons to see more clearly and operate more accurately, and thus it has great potential to be widely used in pancreaticoduodenectomy.
ABSTRACT
Objective:To study the preliminary clinical results of the No-touch technique in laparoscopic pancreaticoduodenectomy for pancreatic head cancer.Methods:A retrospective analysis was consulted on 11 patients who underwent laparoscopic pancreaticoduodenectomy for pancreatic head cancer at the Pancreas Center of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2019 to April 2020. There were 5 males and 6 females, with a Mean±SD age of (63.6±12.2) years. Preoperative evaluation showed all patients were diagnosed to have resectable pancreatic head carcinoma with no local invasion into adjacent arteries and veins, and without metastasis. The surgical strategy consisted of no initial Kocher manoeuvre with no flipping or pulling of the pancreaticoduodenal area. Through unwinding of the pancreatic uncinate process, the pancreatic blood vessels, nerves and lymphatic vessels were completely detached to isolate the tumor. Finally, the pancreaticoduodenal area was totally resected and the digestive tract was reconstructed using the Child’s method. The operation time, intraoperative blood loss, postoperative complications, postoperative pathology and follow-up data of the patients were evaluated.Results:All patients completed the laparoscopic operation without any need for conversion to laparotomy. The operation time of the 11 patients was (422.2±102.2) min, and the bleeding volume was (102.7±65.4) ml. There were 2 patients who developed pancreatic fistula, with 1 patient having a biochemical fistula and 1 patient a grade B fistula. There was no grade C fistula. Other complications included 1 patient with delayed gastric emptying. There were no biliary fistula, no postoperative abdominal bleeding, and no perioperative death. Postoperative pathology showed 6 patients had lymph node metastases, with a positive lymph nodes rate of (4.8±4.4)%. All patients had R 0 resection. The follow-up survival data of the 11 patients showed one patient to develop intrahepatic metastasis 1 month after operation and he died 9 months after operation. Another patient developed liver metastases 2 months after operation. The remaining patients were tumor-free. Conclusion:Laparoscopic pancreaticoduodenectomy using the No-touch isolation and resection technique could achieve complete resection of tumors, and it can safely and effectively be applied to patients with pancreatic head cancer.
ABSTRACT
Objective To investigate the risk factors associated with gastroparesis syndrome after laparoscopic pancreatoduodenectomy which provide reference for clinical prevention.Methods Ninety cases of laparoscopic pancreatoduodenectomy admitted from August 2013 to December 2016 in Traditional Chinese Medicine Hospital of Guangdong Province were studied retrospectively,57 were male(63.3%),the average age was 54.6 years old.Twenty cases were diagnosed postoparative gastroparesis syndrome(22.2%).To screen out the risk factors,31 independent variables were analyzed by univariate analysis and logistic regression.Results Univariate analysis showed that malnutrition,hypoproteinemia,anemia,pylorus-preserving,extensive lymph nodes dissection,anxiety,high blood sugar before operation,delay of enteral nutrition,abdominal infection and postoperative high blood sugar were associated with postoperative gastroparesis(The value of OR were 3.143,3.587,2.852,2.889,3.231,7.071,2.889,5.359,6.000,6.263,P<0.05).Multivariate Logistic regression analysis showed that extensive lymph nodes dissection,anxiety,pylorus-preserving,abdominal infection,delay of enteral nutrition,hypoproteinemia,postoperative high blood sugar were risk factors of postoperative gastroparesis(The value of OR were 17.574,8.931,6.637,6.461,6.446,5.414,5.200;P<0.05).Conclusion Multiple risk factors can lead to gastroparesis after laparoscopic pancreatoduodenectomy,measures should be taken aimed at these risk factors during perioperative period.
ABSTRACT
Objective To investigate the treatment effects of Kansui root on severe acute pancreatitis (SAP) with abdominal compartment syndrome (ACS).Methods 16 cases of SAP were randomly divided into kansui root treatment group and control group according to random number table.Patients in control group received routine treatment including fasting, anti-shock, antibiotics and nutritional support.And the patients in kansui root group received routine treatment plus kansui root therapy.The clinical and laboratory parameters were determined and compared between the two groups.Results The relieving time of abdominal pain, bowel sound, the recovery time of hyperamylasemia, body temperature and leukocyte count in treatment group was (7.6±2.3)d, (6.1 ±3.1)d, (5.9±3.3)d, (5.2 ±3.2) d, (6.3 ±2.1)d, which were significantly shorter than those in control group [ ( 11.7 ± 2.1 ) d, ( 11.2 ± 2.3d, ( 10.2 ± 2.7) d, (9.2 ± 3.5 ) d, ( 11.1 ±3.3)d, P＜0.01 ) ].At the 3rd, 4th and 5th day, the intra-abdominal pressure in treatment group were also significantly lower than those in control group[ ( 19.8 ±3.1 )cmH2O vs(23.7 ±2.9) cmH2O, ( 12.3 ±2.7) cmH2O vs (21.3±1.5)cmH2O,(8.2±3.1)cmH2O vs (17.3 ±2.3)cmH2O,P＜0.05].Conclusions Severe acute pancreatitis has close relationship with Jiexiong syndrome in traditional chinese medicine.Kansui root is an effective therapy for alleviating high intra-abdominal pressure.
