ABSTRACT
Objective:To compare the efficacy and safety of intermittent regional hepatic vascular inflow occlusion with Pringle’s maneuvre for laparoscopic anterior sectionectomy.Methods:From January 2014 to December 2018, 54 patients who underwent laparoscopic right anterior sectionectomy at the Department of Hepatopancreatobiliary Surgery, the Third Affiliated Hospital, Soochow University were recruited into this study. The patients were 40 to 60 years old, and 27 were males and 27 females. Intermittent regional hepatic vascular inflow occlusion was carried out in 24 patients (the intermittent occlusion group). The remaining patients underwent Pringle’s maneuvre (the Pringle group). Postoperative liver function, intraoperative blood loss, intraoperative blood transfusion, operation time and postoperative complications between the two groups were compared.Results:Intraoperative hemorrhage and blood transfusion of the Pringle group (534±42)ml, (2.88±0.54)U were significantly higher than the intermittent occlusion group (374±21)ml, (1.86±0.29)U (all P<0.05). The operation time of the Pringle group was significantly shorter than the intermittent occlusion group ( P<0.05). Two patients developed CO 2 embolism in each group, which led to 2 patients in the intermittent occlusion group being converted to open operations. Postoperative hepatic function (except albumin) of the intermittent occlusion group was significantly better than the Pringle group, while the hospital stay of the intermittent occlusion group was significantly shorter than the Pringle group (all P<0.05). Six patients (25.0%) developed postoperative complications in the intermittent occlusion group versus 8 (26.7%) in the Pringle group ( P>0.05). Conclusion:Intermittent regional hepatic vascular inflow occlusion reduced intra-operative hemorrage and hepatic impairment, and shortened hospital stay. However, it required higher operation skills and it should gradually be promoted.
ABSTRACT
Objective:To evaluate partial splenectomy (LPS) in the treatment of benign solid tumors of the spleen.Methods:The clinical data of patients with benign solid tumors of spleen treated by laparoscopy from Jan 2010 to Jun 2018 in the Third Affiliated Hospital of Soochow University was retrospectively analyzed. Patients were divided into LPS group and laparoscopic total splenectomy (LTS) group.Results:There were 21 cases in LPS group and 25 cases in LTS group. Differences between the two groups, operative time, blood loss, transfusion rate, maintenance of drain, postoperative hospital stay, costs, postoperative WBC and platelet count, and postoperative complications such as hemorrhage, fever, splenic fossa effusion, pancreatic fistula, venous thrombosis were statistically insignificant. However, the postoperative incidence of thrombocythemia in the LPS group were significantly lower compared to the LTS group (χ 2 =4.293, P<0.05). Conclusions:Patients with benign solid tumors of the spleen will benefit more from LPS compared to LTS.
ABSTRACT
Objective To evaluate regional left sided in and out flow hepatic flow occlusion in laparoscopic left hemi-hepatectomy compared with in hepatic flow occlusion.Methods From Jan.2016 to Dec.2017,34 patients underwent laparoscopic left hemi-hepatectomy with regional hepatic in-out flow occlusion.Results were compared with 52 patients undergoing laparoscopic left hemi-hepatectomy under leftsided hepatic inflow occlusion only.Results Compared to hepatic inflow occlusion,regional hepatic in and out flow occlusion in laparoscopic left hemi-hepatectomy lead to a 0.46 hour longer operation time,20 ml less intraoperative blood loss and 0.62U less blood transfusion,reduced hepatic function impairment and 1.41 days shorter hospital stay.Conclusions Regional hepatic in-out flow occlusion in laparoscopic left hemi-hepatectomy can reduce intraoperative hemorrhage and lower the risk of CO2 embolism.

ABSTRACT
Objective@#To evaluate the clinical significance of C-reactive protein/albumin ratio in predicting the postoperative prognosis of pancreatic cancer patients.@*Methods@#The clinical date of 97 patients with resectable pancreatic cancers who treated at Department of Hepatobiliary and Pancreatic Surgery, the third Affiliated Hospital of Soochow University from January 2005 to December 2015 were analyzed retrospectively. The cut-off value of CRP/Alb ratio was determined by the receiver operating characteristic(ROC) curve. According to the CRP/Alb ratio, patients were respectively divided into two groups: the high group(CRP/Alb ratio≥0.109) and the low group(CRP/Alb<0.109). The relationships between CRP/Alb ratio and clinical characteristics were analyzed by χ2 test. Median survival and 1-year overall survival rate(OS) was calculated by Kaplan-Meier method.The risk factors of patients with poor prognosis were analyzed by univariate and multivariate Cox regression analysis model.@*Results@#Tumor TNM stage(χ2=4.280, P=0.039) and differentiation(χ2=6.635, P=0.010) had significant relationship with CRP/Alb ratio. The median survival of higher CRP/Alb ratio group and lower CRP/Alb ratio group was 15 months and 23 months respectively. Compared with lower CRP/Alb ratio group, the 1-year OS of higher CRP/Alb ratio group decreased remarkablely, and the difference was statistically(χ2=10.207, P=0.001). Moreover, median survival and OS were decreased in patients with advanced age(≥65 years old: χ2 =5.338, P=0.021), high TNM stage(ⅡB-Ⅲ: χ2 =10.529, P=0.001), poor tumor differentiation(χ2=5.380, P=0.020), vascular invasion(χ2 =7.856, P=0.005) and positive surgical margin(χ2=9.059, P=0.003). A high CRP/Alb ratio was identified as an independent risk factor of poor prognosis for patients with pancreatic cancer(HR=1.832, 95% CI: 1.067-3.144, P=0.028). Besides, old age(HR=1.684, P=0.014), high TNM stage(HR=1.666, P=0.031), vascular invasion(HR=1.834, P=0.024) and positive surgical margin(HR=2.205, P=0.023) were also included.@*Conclusion@#Preoperative CRP/Alb ratio can be an important clinical factor for assessing the prognosis of patients with resectable pancreatic cancers, and high CRP/Alb ratio suggests poor prognosis.
ABSTRACT
Objective To investigate the strategies in dealing with intraoperative CO2 embolizm during Laparoscopic hepatectomy (LH).Methods We collected and analyzed data from patients who underwent laparoscopic hepatectomy (LH) in our hospital from Jan.2013 to Aug.2017.There were 321 patients.The criteria for the diagnosis of CO2 embolism were rapid intraoperative decrease in petCO2 and SPO2 accompanied with tachyarrhythmia.Results 12 patients were diagnosed to have CO2 embolism.The rate was 3.7％.For these 12 patients,10 patients were dealt with laparoscopically and 2 patients were converted to open surgery.Conclusion CO2 embolism did not rarely occur in LH patients.Sophisticated operations and careful manipulation in LH are the only ways to prevent CO2 embolism.
ABSTRACT
Background and purpose:Thyroid carcinoma is a common endocrine tumor with an incidence that has increased over recent decades. The aim of the present study was to investigate the effectiveness of carbon nano-par-ticles-labeled lymph nodes in neck dissection for papillary thyroid cancer (PTC), focusing on the protectiveness for the recurrent laryngeal nerve (RLN) and parathyroid glands.Methods:Forty-eight patients with PTC treated from Apr. to Aug. 2015 were randomly divided into two groups. Group A patients (24 patients) were treated with lobectomy/total thyroidectomy plus unilateral/bilateral central lymph node dissection by conventional meticulous capsular dissection technique; Group B patients (24 patients) were treated with the same surgical procedures as group A, 5 min after the injection of carbon nano-particles. The operative time, intra-operative blood loss, incidence of RLN injury, incidence of transient hypocalcemia, the number of total lymph nodes and the ratio of metastatic nodes were collected and analyzed. Results:For unilateral lobectomy, the number of lymph nodes in group B was signiifcantly greater than that in group A (P<0.05). For total thyroidectomy, the operative time, and the incidence of transient hypocalcemia in group B were both lower than those in group A (P<0.05), and the number of total lymph nodes was signiifcantly higher than that in group A (P<0.05). In group B, the ratio of metastatic nodes were 26.7% (unilateral) and 33.3% (bilateral) in stained lymphnodes, and 11.8% and 25.9% in non-stained lymph nodes.Conclusion:The carbon nano-particles-labeled lymph nodes in neck dissection could facilitate to protect parathyroids and increase the number of lymph nodes, especially in total thyroidectomy plus bilateral central lymph node dissection.
