ABSTRACT
Objective:To study the feasibility and safety in treatment of trauma to right posterior liver using laparoscopic surgery with patients in the left semiprone position.Methods:The clinical data of consecutive patients who were diagnosed to have trauma to the right posterior liver and were treated with laparoscopic surgery with patients in the left semiprone position at the Department of Hepatobiliary Surgery, the Affiliated Hospital of Youjiang Medical University for Nationalities between February 2016 and August 2020 were retrospectively analysed. The patients’ gender, age, mechanisms of injury, operative methods, operative time, amounts of abdominal effusion, degrees of liver injury, extents of intraoperative bleeding, amounts of postoperative drainage, lengths of postoperative hospital stay, and major postoperative complications were recorded and analyzed.Results:Among the 18 patients, there were 16 males and 2 females, aged (41.6±14.4) years. The mechanisms of liver trauma were caused by fall injury ( n=10), traffic accidents ( n=4), blunt injury ( n=2) and penetrating injury ( n=2). The levels of injuries were level Ⅲ in 16 patients and level Ⅳ in 2 patients. Laparoscopic suture repair was performed in 8 patients, partial hepatectomy in 4 patients, electrocoagulation hemostasis in 4 patients and ligation of bleeding vessels in 2 patients. All were successful in hemostasis. Abdominal effusion was (1 528.8±373.2) ml, intraoperative blood loss (80.6±16.7) ml, operation time (88.5±9.1) min, postoperative hospital stay 7 days and postoperative total drainage (93.8±13.6) ml. Ten patients were complicated with right pleural effusion, and they recovered with conservative treatment. There were no bile leakage, infection and other complications. Conclusion:Trauma to right posterior liver treated with laparoscopic with surgery patients in the left semiprone position had the advantages of adequate exposure which facilitated surgical hemostasis, resulting in minimal collateral damages and short hospital stay. The treatment was feasibility and safe.
ABSTRACT
Objective To study the safety and efficacy of laparoscopic resection of hemangioma in the right posterior hepatic section without any blood flow occlusion.Methods Patients with hemangiomas in the right posterior section of liver operated from January 2016 to June 2018 in the Affiliated Hospital of Youjiang Medical College for Nationalities were studied retrospectively.There were 19 females and 9 males.The average age was (37.9 ± 6.1).The operation methods,perioperative factors,hospitalization cost and follow-up outcomes were recorded and analyzed.Results 28 patients with hemangiomas were treated with laparoscopic resection of right posterior hepatic section without any blood flow occlusion.An ultrasound scalpel was applied to split the liver in 27 patients,and ultrasound scalpel combined with Ligasure to split the liver in 1 patient.The mean diameter of the hepatic hemangiomas was (6.7 ± 1.3) cm.The intraoperative blood loss was (330.4 ± 139.0) ml and the operation time was (87.4 ±27.9) min.One patient required conversion to open surgery due to rupture and bleeding of the hemangioma.The conversion rate was 3.6％ (1/28).The postoperative drainage time was (45.4 ± 18.9) h.The postoperative hospitalization time was (7.5 ± 1.3) d,and the hospitalization cost was (3.1 ± 0.5) ten thousand yuan.No death or serious complications occurred.No reoperation was needed.The follow-up period ranged from 1 to 30 months,and all the patients were well on follow-up.Conclusions Laparoscopic resection of hemangioma in the right posterior hepatic section without any blood flow occlusion was safe and efficacious.This method can be used for hemangiomas in the right posterior section of liver.
ABSTRACT
Objective To explore the risk factors affecting T-tube sinus tract formation after common bile duct exploration and T-tube drainage by spiral computed tomography (SCT)examination.Methods The clinical data of 465 patients undergoing common bile duct exploration and T-tube drainage at the Affiliated Hospital of Youjiang Medical College for Nationalities from May 2011 to December 2013 were retrospectively analyzed.The residual stones and biliary stricture were detected by T-tube cholangiography,and the T-tube sinus tract formation in all the patients was detected by SCT examination at postoperative week 2.The factors affecting sinus tract formation were analyzed,including gender,age,albumin (Alb),C-reactive protein,alanine transaminase (ALT),total bilirubin (TBil),hemoglobin (Hb),surgical method,effusion around T tube,reoperation,diabetes.Univariate analysis was done using the chi-square test.Multivariate analysis was done using the Logistic regression.Results T-tubes of 465 patients were clear without residual stones.T-tube in the 397 patients was removed when the sinus tract formation was confirmed by CT examination at postoperative week 2.T-tubes in other patients were removed when the sinus tract formation was detected by CT reexamination at postoperative week 4.In univariate analysis,Alb,surgery method,effusion around T-tube and diabetes were important factors affecting T-tube sinus tract formation (x2 =50.750,7.671,19.022,15.373,P ＜ 0.05).Alb ＜ 30 g/L,laparoscopic surgery,effusion around T-tube and diabetes were independent risk factors affecting T-tube sinus tract formation in multivariate analysis [Odds ratio =1.135,0.493,0.262,0.363; 95％ confidence interval:1.061-1.214,0.280-0.865,0.104-0.658,0.156-0.843,P ＜ 0.05].Conclusions The T-tube removal is determined according to the sinus tract formation by CT examination at week 2 after common bile duct exploration and T-tube drainage.Alb ＜ 30 g/L,laparoscopic surgery,effusion around T-tube and diabetes are independent risk factors affecting T-tube sinus tract formation.
ABSTRACT
Objective To investigate the relationship between single nucleotide polymorphisms (SNPs),serum CD31 and HCC.Methods We analyzed three single nucleotide polymorphisms of CD31 gene Leu125Val,Asn563Ser and Gly670Arg in 190 HCC patients and 210 age and sex matched controls in a Chinese population,using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy,and the serum level of CD31 was determined by enzyme-linked immunosorbent assay (ELISA).Results The distributions of CD31 gene Asn563Ser and Gly670Arg polymorphisms were not significantly different between HCC and control group (x2 =0.491,P ＞ 0.05),but the CD31 gene Leu125Val polymorphism was significantly different (x2 =10.988,P ＜ 0.05).The relative risk suffering from HCC of Val allele was 1.583 times of the Leu allele carriers(OR =1.583,95％ CI,1.197-2.093,P =0.001) ; Serum level of CD31 Val allele carriers was significantly higher than that of no carriers(x2 =10.408,P ＜ 0.05).Consistent with the results of the genotyping analyses,CD31 gene Leu125Val,Asn563Ser and Gly670Arg polymorphisms showed strong linkage disequilibrium,the Val-Ser-Arg haplotype was associated with a significantly increased risk of HCC as compared with the controls (OR =1.496,95％CI:1.095-2.046,P =0.011).Conclusions CD31 gene Leu125Val polymorphism and its Val-Ser-Arg haplotype were associated with HCC,Val allele is an important genetic susceptibility gene for HCC.CD31 Val allele carriers may subject to higher risk of HCC with enhanced CD31 expression.
