Objective To study the clinical outcomes of 28 pancreatic cancer patients who underwent total pancreaticoduodenectomy.Method The clinical data of 28 patients with pancreatic cancer who underwent total pancreaticoduodenectomy from January 2009 to March 2015 were retrospectively analyzed.Results Among the 28 patients,complications occurred in 11 (39.2％) after the operation.There were 7 patient having Grade Ⅱ,4 Grade] complications.No patient died within 30 days after the operation.Fol low-up of 25 patients showed a median survival of 13.5 months.There were 24 patients with pancreatic ductal adenocarcinoma,and the median survival was 13 months.Conclusions Total pancreaticoduodenectomy could not improve long-term survival but it decreased postoperative complications and improved postoperative quality of life.In selected patients,total pancreaticoduodenectomy could be a rational option.

Objective:To study the influencing factors in predicting conversion of laparoscopic liver tumor resection to open surgery to provide references for selection of patients for laparoscopic hepatectomy.Methods:The clinical data of 222 patients who were planned to undergo laparoscopic liver tumor resection at Ningbo Medical Center Lihuili Hospital from December 2015 to November 2018 were analyzed retrospectively. There were 146 males and 76 females, with an average age of 58.1 years. These patients were divided into the conversion group ( n=24) and the laparscopic group ( n=198) according to whether intraoperative conversion to open surgery was carried out. Chi-square test was used to evaluate relevant factors of conversion. Logistic regression analysis was used for multivariate analysis and to find out independent risk factors of conversion. Results:The conversion rate was 10.8% (24/222). Univariate analysis showed that hypertension, history of abdominal surgery, liver cirrhosis, tumors located at posterosuperior segments and major liver resection were significantly associated with conversion (all P<0.05). Multivariate analysis showed that the risk factors which were independently associated with conversion were liver cirrhosis ( OR=2.611, 95% CI: 1.018-6.701), tumors located at posterosuperior segments ( OR=6.115, 95% CI: 2.207-16.941), and major liver resection ( OR=3.361, 95% CI: 1.150-9.825)(all P<0.05). Conclusion:Patients who were planned for laparoscopic liver tumor resection with liver cirrhosis, tumors at posterosuperior segments or major liver resection were at higher risks of conversion to open surgery.

Objective To find the potential risk factors for pancreatic fistula after distal pancreatectomy.Methods Clinical data of 125 cases of consecutive distal pancreatectomy in Ningbo Lihuili Hospital from January 2006 to June 2013 were retrospectively analyzed.Results In all the 125 patients with distal pancreatectomy,pancreatic fistula was the most common surgical complication (43/125,34.4％),including 27 cases of grade A fistula,16 cases of grade B pancreatic fistula.Multivariate analysis showed that the texture of the pancreas and main pancreatic duct ligation were the independent risk factors for pancreatic fistula (all P ＜ 0.05).Conclusions Pancreatic fistula was the most common surgical complication of distal pancreatectomy.The texture of the pancreas and main pancreatic duct ligation effect the occurrence of postoperative pancreatic fistula.

Objective To analyze the related risk factors for delayed gastric emptying ( DGE) after pancreaticoduodenectomy .Methods Clinical data on 308 patients who underwent pancreaticoduodenectomy at Ningbo Lihuili hospital from January 2009 to December 2014 were retrospectively analyzed , and patients were divided into DGE group and non-DGE group.Univariate analysis and multivariate logistic regression analysis were used to study the risk factors associated with DGE during perioperative period .Results DGE occurred in 55 patients (17.9%).The incidences of grade A, grade B and grade C DGE were 7.1%(22/308), 6.2%(19/308) and 4.5%(14/308), respectively.The univariate analysis showed the method of pancreatic digestive tract reconstruction ( pancreaticogastrostomy or pancreaticojejunostomy ) , postoperative pancreatic fistula, postoperative biliary fistula and postoperative intraabdominal infection were risk factors for DGE after surgery. Multivariate analysis indicated that the method of pancreatic digestive tract reconstruction (OR=1.19, P=0.046), postoperative pancreatic fistula ( OR=1.33, P=0.014), postoperative biliary fistula (OR=1.43, P=0.047) and postoperative intraabdominal infection (OR=1.51, P=0.001) were independently associated with DGE . Postoperative pancreatic fistula (OR=3.692, P=0.021) and intraabdominal infection (OR=3.725,P=0.003)were also the independent risk factors for Grade B and Grade C DGE. Conclusions DGE after pancreaticoduodenectomy was strongly related to the postoperative complications .Postoperative pancreatic fistula , biliary fistula and intraabdominal infection were associated with increased risk of DGE , while pancreaticogastrostomy reduced the incidence of DGE by decreasing the incidence of pancreatic or biliary fistula .

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) after liver resection for hepatocellular carcinoma (HCC) with tumor thrombus in the main trunk and/or first branch of portal vein,and to clarify prognostic factors affecting survival.Methods From 2005 to 2009,there were 358 consecutive patients with HCC who underwent surgical resection in our Department.In 55 patients (15 ％),portal vein tumor thrombus (PVTT) was found intraoperatively or postoperatively during histopathological examinations to involve the first portal branch,main portal trunk,or contralateral portal branch.In this retrospective study,these 55 patients were divided into two groups:Group A,29 patients received postoperative TACE,and Group B,26 patients who did not receive TACE.The clinical data and survivals were compared between the two groups.Prognostic factors were indentified using univariate analysis,followed by multivariate regression analysis using the Cox proportional hazards model.ResultsThere were no significant differences in the demographic clinical data between Group A and Group B.The overall 1-,2- and 3-year survivals for the 55 patients were 63.3 ％,51.4 ％ and 43.5 ％,respectively.The accumulative 1-,2- and 3-year survivals for group A were 71.4 ％,60.1 ％ and 50.1 ％,respectively.The corresponding figures for group B were 56.7％,21.7％ and 10.4％,respectively.Multiple tumors,intrahepatic metastases,hepatic vein thrombus,and invasive type of tumor thrombus were found to be risk factors for short-term survival on univariate analysis,while the latter 3 factors were further found to be significant prognostic factors in the Cox proportional hazards model.Postoperative TACE was shown to be a significant factor in both univariate and multivariate analyses.ConclusionLiver resection was beneficial for some patients with portal vein tumor thrombus.Postoperative TACE further improved the prognosis and prolonged survivals in these patients.

Objective To compare the clinical results of laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and open spleen-preserving distal pancreatectomy (OSPDP).Methods From Jan 2014 to Aug 2017,the clinical results of 30 patients undergoing LSPDP were compared with those of 20 OSPDP patients.The postoperative pancreatic fistula rate was the main observation index.Results There was significant difference in operation time [(140.33 ±55.93) min vs.(182.71 ±43.51)min],blood loss [(175.61 ± 180.78) ml vs.(253.51 ± 176.06) ml],postoperative hospital stay [(6.16 ± 7.22) d vs.(8.85 ± 9.36) d],postoperative exhaust [(2.17 ± 1.43) d vs.(3.10 ± 1.89) d],and postoperative feeding time [(2.26 ± 1.78)d vs.(3.42 ±2.01)d] between LSPDP and OSPDP.LSPDP group was better than OSPDP group (all P ＜ 0.05).The rate of postoperative pancreatic fistula (66.7％ vs.70.0％) and overall complications (80％ vs.90.0％) were not statistically different between the two groups.Pancreatic leakage occurred in 20 cases,lung infection in 1 case,peritoneal infection in 1 case and chylous leakage in one case in LSPDP group,while pancreatic leakage in 14 cases,lung infection in 2 cases,and peritoneal infection in 2 cases in OSPDP group,all were cured by conservative therapy.Conclusions LSPDP is a safe,effective,less traumatic and more economic surgical approach for benign cystic tumors located at the body or tail of the pancreas.

OBJECTIVETo investigate the value and safety of the surgery with vascular resection and reconstruction during pancreatectomy for pancreatic cancer.

METHODSThe clinical data of 206 patients with pancreatic cancer who underwent radical resection were retrospectively analyzed from January 2009 to March 2014 in Lihuili Hospital, Medical center of Ningbo.All cases were divided into non-vascular resection group(132 cases), the combined vein resection group(66 cases) and the combined arterial resection group(8 cases). The peri-operation data, the incidence of postoperative complications and the survival were compared in pairs among three groups.All patients were followed up till September 2014.

RESULTSThere were no statistical differences for the preoperative data among three groups.The operation time and the blood loss (M(QR)) were (347±96)minutes and (500(400)) ml in non-vascular resection group, (425±91)minutes and (800(500))ml in combined vein resection group, (508±120)minutes and (1 750(2 075))ml in combined arterial resection group, with significant differences among three groups(all P<0.01). The incidence of postoperative complication was 16.7%(22/132) in non-vascular resection group, 28.8%(19/66) in combined vein resection group, and 6 cases in combined arterial resection group, respectively.There were significant differences between non-vascular resection group and combined vein resection group(P<0.05), non-vascular resection group and combined arterial resection group(P<0.05), as well as between combined vein resection group and combined arterial resection group(P<0.05). The median survival time was 15 months for non-vascular resection group, 15 months for combined vein resection group, and 12 months for combined arterial resection group.No significant difference was found among three groups(all P>0.05). The postoperative mortality was nil for all of groups.

CONCLUSIONSCompared with non-vascular resection, combined vein resection can be performed safely with a similar prognosis. The surgery of combined arterial resection could only be justified when R0 resection for pancreatic cancer could be achieved for highly selected patients.

Objective:To investigate the correlation between modified Glasgow prognostic score (mGPS) and prognosis of intrahepatic cholangiocarcinoma (ICC) patients after radical surgical resection.Methods:The clinical data of 126 patients with intrahepatic cholangiocarcinoma undergoing radical surgical resection at Ningbo Medical Centre Lihuili Hospital from Jan 2011 to Dec 2020 were retrospectively analyzed. The patients were scored according to the mGPS-related scoring standards, and the differences in tumor clinicopathological characteristics and prognosis were compared between patients with different score levels.Results:Firty-eight cases were included in group 0, 41 cases in group 1, and 27 cases in group 2. The 1- and 3-year survival rates in group 0 were 85.8% and 52.3%, the 1- and 3-year survival rates in group 1 were 73.2% and 23%, and the 1- and 3-year survival rates in group 2 were 73.3% and 0. The difference was statistically significant ( P<0.05). Univariate analysis showed that age, mGPS, CA19-9, tumor diameter, and tumor differentiation were related at the prognosis of ICC. Multivariate analysis showed that age, tumor differentiation, tumor diameter and mGPS were independent risk factors for the prognosis of ICC. Conclusion:mGPS is an independent risk factor affecting the prognosis of ICC patients.

Objective:To study the risk factors of unplanned reoperation within 30 days after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 207 patients who underwent LPD in the Lihuili Hospital Affiliated to Ningbo University from February 2017 to October 2022 were retrospectively analyzed. There were enrolled 118 males and 89 females, aged (65.1±11.1) years old. Patients were divided into the reoperation group ( n=15) and non-reoperation group ( n=192) based on whether unplanned reoperation was performed within 30 days after LPD. The risk factors of unplanned reoperation were analyzed with univariate and multivariate logistic regression analysis. Results:The rate of unplanned reoperation within 30 days after LPD was 7.2%(15/207). The unplanned reoperation group exhibited a higher incidence of complications 80% (12/15), mortality 13.3% (2/15), and extended hospital stay (32.9±20.1)d compared to the non-reoperation group, which incidences of complications, mortality and extended hospital stay were 40.1% (77/192)( χ2=9.04, P=0.003), 0.5%(1/192)( χ2=8.28, P=0.004), and (17.9±8.6)d ( t=-2.79, P=0.014), respectively. Unplanned reoperation was associated with diabetes, intraoperative bleeding >130 ml, preoperative serum prealbumin <0.15 g/L, pancreatic texture and pancreatic duct diameter (all P<0.05). Multivariate logistic regression analysis identified diabetes ( OR=4.991, 95% CI: 1.431-17.415), preoperative serum prealbumin <0.15 g/L ( OR=4.06, 95% CI: 1.178-14.043), soft pancreatic texture ( OR=3.900, 95% CI: 1.146-13.272) and pancreatic duct diameter ≤3 mm ( OR=3.449, 95% CI: 1.009-11.789) as independent risk factors for unplanned reoperation within 30 days. Conclusion:Preoperative diabetes, preoperative serum prealbumin levels <0.15 g/L, soft pancreatic texture and pancreatic duct diameter ≤3 mm were independent risk factors for unplanned reoperation within 30 days after LPD.

Objective To investigate the clinical outcomes of liver transplantation by using donation after cardiac death (DCD) in single center.Methods The clinical data of 115 DCD donors and recipients of liver transplantation from Jan 2012 to Sep 2017 at our institution were analyzed,including preoperative general data,intraoperative status,and postoperative early complications.Patients were followed up to Oct 30th,2017.The measurement data with normal distribution were analyzed by t test,the enumeration data were analyzed by chi-square test or Fisher exact probability test,and the Kaplan-Meier method was used for survival analysis.Results All of the 115 donors were within China category Ⅲ using the classification of China donor after cardiac death.Donor graft mean warm ischemic time and cold ischemic time was (10 ± 4) min and (6.1 ± 1.7) h,respectively.All of the recipients underwent liver transplantation successfully.The mean preoperation MELD score was 14 ± 7.Seven patients were ABO-incompatible liver transplantation (A→O,3 cases,B→O 2 cases,AB→O 1 case,AB→A 1 case).19 patients (16.5％) had postoperative complications (Clavien-Dindo classification grade Ⅲ-Ⅴ).The perioperative mortality was 2.6％ (3 cases).All patients were followed up for an average (21 ± 17) mon.Patients 1-,3-,and 5-year survival rates were 93.6％,81.8％,and 77.5％,respectively.Conclusion The outcome of DCD liver transplantation is favorable at our institution under careful donor and recipient selection and intensive perioperative management.
