ABSTRACT

Objective:To study the technical and essential steps in laparoscopic selective devascularization with paraesophageal veins-preservation.Methods:To retrospectively analyze the clinical data of 13 cirrhotic patients who underwent laparoscopic selective pericardial devascularization for portal hypertension at the Department of Hepatobiliary and Pancreatic Surgery, Zhejiang Provincial People's Hospital from January 2019 to March 2020. There were 9 males and 4 females with age ranging from 41 to 83 years (median 51 years). The operative time, intraoperative blood loss, postoperative complications and follow-up data were analyzed.Results:All the 13 patients completed theoperation, no patient stopped the operation or transferred to laparotomy. The operation time was (170±32) min.The intraoperative bleeding was (160±30) ml. The postoperative hospital stay was (6.1±1.1) days. There were no complications, including pancreatic leakage and intra-abdominal infection. On follow-up which ranged from 1 to 15 months, one patient developed portal vein thrombosis, no upper gastrointestinal rebleeding.Conclusions:Preservation of esophageal veins in laparoscopic selective devascularization is an accurate surgery which requires close teamwork and rich experience in laparoscopic surgery. The preservation of the main trunk of the gastric coronary vein and integrity of the esophageal veins are the keys to the surgery which is safe and feasible.

ABSTRACT

Objective:To compare the treatment outcomes between laparoscopic versus open radical resection for hilar cholangiocarcinoma (HCCA).Methods:From January 2017 to January 2020, the clinical data of 34 patients who underwent radical resection for HCCA were retrospectively collected and analyzed. These patients were divided into the laparotomy group ( n=17) and the laparoscopic group ( n=17) based on the operation they received. Clinical data including perioperative outcomes, oral re-intake time, first out-of-bed activity time, drainage tube removal time, postoperative hospital stay, 30-day and 90-day mortality rates were compared between groups. Results:Of 34 patients who underwent radical for HCCA in the study, there were 16 males and 18 females, aged (64.3±1.7) years. The mean operation time of the laparotomy group was significantly less than those in the laparoscopic group [(436.2±33.4) vs (522.1±24.0) min, P<0.05]. The 2 groups showed comparable results in extent of operation, intraoperative bleeding, incidences of portal vein reconstruction, yields of lymph nodes, and tumor diameter. The laparoscopic group showed advantage trends over the laparotomy group in incidences oral re-intake time [(4.7±0.3) vs (4.6±0.3) days], first out-of-bed activity time [(2.9±0.4) vs (2.2±0.3) days], drainage tube removal time [(12.7±1.3) vs (11.1±1.0) days] and postoperative hospital stay [(18.3±1.7) vs (15.8±1.3) days], but the differences failed to reach statistical significance ( P>0.05). Conclusion:Compared with open surgery, laparoscopic radical resection of HCCA in properly selected patients, was safe and feasible. There were comparable clinical outcomes.

ABSTRACT

Objective:To study the causes of hemorrhage after laparoscopic pancreaticoduodenectomy (LPD) and to develop countermeasures in its prevention.Methods:The clinical data of 215 patients who underwent LPD at the Department of Hepatobiliary and Pancreatic Surgery of Zhejiang Provincial People's Hospital from December 2013 to May 2020 were reviewed. The patients’ clinical data including gender, age, comorbidities and postoperative complications such as bleeding, pancreatic fistula, biliary fistula and intraperitoneal infection were studied, with the aims to analyze the causes, clinical manifestations and treatment results of post-pancreaticoduodenectomy hemorrhage (PPH) after LPD.Results:Of 215 patients, there were 132 males and 83 females, aged (60.7±10.3) years. PPH occurred in 20 patients, incidence rate was 9.30%(20/215). Early hemorrhage was mainly caused by inadequate hemostasis or loosening of vascular clips, while delayed hemorrhage was mainly caused by gastrointestinal fistula with vascular erosion, arterial injury by intraoperative energy instruments or pseudoaneurysms. Among the 20 patients, 6 patients had early hemorrhage and 14 delayed hemorrhage. There was 1 patient with grade A, 10 with grade B and 9 with grade C hemorrhage. Thirteen patients developed pancreatic fistula, 1 biliary fistula, and 2 intraperitoneal infection. One patient responded well to conservative treatment. Hemostasis was successfully achieved by gastroscopy ( n=1) and interventional therapy ( n=7). Eleven patients required laparotomy for hemostasis. In this study, 14 of 20 patients survivied PPH and 6 patients died. The mortality rate was 30% (6 of 20 patients with PPH). Conclusions:Early hemorrhage was caused by inadequate hemostasis or loosening vascular clips, while delayed hemorrhage was related to gastrointestinal fistula with vascular erosion, arterial injury by intraoperative energy instrument or pseudoaneurysm. Careful hemostasis, adequate protection of blood vessels, and accurate anastomosis should be performed in LPD. DSA angiography should be used for arterial hemorrhage which progressed very rapidly. Interventional therapy including embolism and stenting were means to control arterial bleeding in PPH. Decisive surgical exploration when interventional therapy failed was important in reducing the mortality rate of these patients.

ABSTRACT

Objective To investigate the effects of miRNAs-107 (miR-107) on pancreatic cancer proliferation,senescence and invasion.Methods MiR-107 expression levels in 3 pancreatic cancer cell lines PANC-1,ASPC-1,BXPC-3 and normal pancreatic HTERT-HPNE cells were studied by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).PANC-1 cells were transfected with 50 nmol/L anti-miR-107 or negative control using Lipofectamine 2000.After transfection,the miR-107 expression was measured by qRT-PCR.Cell proliferation was tested by methylthiazol tetrazolium (MTT) assay.Cell senescence was detected by β-galactosidase staining.The expression levels of PCNA,P16INK4A and MMP2 were measured by qRT-PCR.Results Compared with the HTERT-HPNE cells,the expression level of miR-107 in 3 pancreatic cancer cell lines was significantly increased (P < 0.01).After transfected with 50 nmol/L anti-miR-107,cell proliferation was inhibited,and cell senescence were increased in PANC-1 cells (P < 0.05),and there was no obvious change in cell invasion.Compared with the HTERT-HPNE cells,after transfected with anti-miR-107,the PCNA expression was significantly decreased and P16INK4A was significantly increased,but expression of M MP2 didn't change significantly.Conclusions These results demonstrate that miR-107 promotes the proliferation and escapes cell senescence in PANC-1 cells by targeting PCNA and P16INK4A.But it has no obvious effects on cell invasion.Therefore,it may be a new target for the biologic therapy for pancreatic cancer.

ABSTRACT

Objective@#To investigate the role of "Hong′s single-stitch duct to mucosa pancreaticojejunostomy(HSDMP)" in laparoscopic pancreaticoduodenectomy (LPD).@*Methods@#The clinical data including perioperative and short-term outcomes of 51 cases of LPD with HSDMP which performed in Zhejiang Provincial People′s Hospital(33 cases) and Frist Clinical Hospital of Jilin University(18 cases) between April and October 2016 were reviewed retrospectively. There were 31 male patients and 20 female patients. The mean age was(59±11)years. Body mass index (BMI) was 18 to 28 kg/m2 and the average BMI was (23.2±4.4)kg/m2. Preoperative diagnosis: 18 cases with pancreatic mass, 26 cases with peri-ampullary tumor, 3 cases with intra-ductal papillary mucinous neoplasms, 2 cases with duodenal carcinoma, 2 cases with serous cystadenoma.@*Results@#Fifty-one patients accepted LPD using HSDMP. One patient underwent LPD combined with resection of superior mesentery vein. The mean operation time was (307±69)minutes, the mean diameter of pancreatic duct for reconstruction was (3.1±1.1)mm.The mean operation time for HSDMP was (34±5) minutes, the estimated blood loss was (170±127)ml. Twelve cases(23.5%) had pancreatic fistula according to International Study Group definition, including 9 cases(17.6%) of grade A and 3 cases (5.9%) of grade B. Five cases(9.8%) had delayed gastric empty, 5 cases(9.8%) had bile leakage and 2 cases(3.9%) had pulmonary infection postoperative.All these complications were treated by non-surgical strategies. One patient(2.0%) suffered from postoperative intra-abdominal bleeding and recovered after reoperation. Pathologic results showed pancreatic ductal adenocarcinomas in 20 cases(39.2%), non-pancreatic original peri-ampullary tumors in 23 cases(45.1%), intra-ductal papillary mucinous neoplasms in 3 cases(5.9%), duodenal carcinoma in 2 cases(3.9%), serous cystadenoma in 2 cases(3.9%) and neuroendocrine tumors in one case(2.0%).@*Conclusions@#HSDMP could not only reduce the incidence of clinical pancreatic fistula, but also save operation time. It is a feasible and safe method for pancreaticojejunostomy.

ABSTRACT

Objective To evaluate the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on recurrence after hepatectomy for AFP negative hepatocellular carcinoma (HCC).Methods Clinical data of 68 AFP negative HCC patients undergoing radical hepatectomy from September 2010 to January 2013 were analyzed retrospectively.According to preoperative NLR,patients were divided into low NLR group (NLR < 2.78) and high NLR group (NLR ≥ 2.78),respectively.Univariate analysis was performed to assess for a significant difference in clinicopathological characteristics influencing disease-free suvival after hepatectomy.A multivariate analysis was performed by Cox regression for variables significant on univariate analysis.Kaplan-Meier method was used to assess disease-free survival rate.Results The overall 1,2,and 3-year disease-free survival rate was 79.7%,37.5%,and 18.2% respectively.The disease-free survival of high NLR group was significantly lower than the low NLR group (1,2,and 3-year overall survival were 70.3%,35.1%,and 13.5% vs 85.2%,40.7%,and 18.5%,respectively,P =0.042).Preoperative NLR ≥2.78,tumor size (> 5 cm),microvascular invasion and liver cirrhosis were risk factors of poor disease-free survival.Cox regression analysis revealed that all of these four factors were independent predictors of poorer disease-free survival.Conclusions Preoperative NLR≥2.78 was one of independent adverse predictors for disease-free survival in AFP negative HCC patients after hepatectomy.
