Objective To investigate the clinical efficacy of laparoscopic hepatectomy for intrahepatic cholangiocarcinoma (ICC).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 62 patients with ICC who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University (32 patients) and the First Hospital Affiliated to Army Medical University (30 patients) between January 2013 and January 2018 were collected;there were 35 males and 27 females,aged from 25 to 77 years,with an average of 60 years.According to the preoperative and intraoperative situations,lymph node dissection was performed,and anatomical or non-anatomical laparoscopic hepatectomy were performed based on tumor size and location.Observation indicators:(1) surgical and postoperative recovery;(2) pathological examination results;(3) follow-up and survival situations.Follow-up was conducted by telephone interview and outpatient examination once every 3 months to detect tumor-free survival and overall survival of patients up to June 2018.Measurement data with normal distribution were represented as Mean±SD.Measurement data with skewed distribution were represented as M (range).Count data were described as absolute number and percentage.The survival curve and rate were drawn and calculated by the Kaplan-Meier method.Results (1) Surgical and postoperative recovery:all the 62 patients received successful laparoscopic hepatectomy,without conversion to open surgery or preoperative death,including 40 with anatomical hepatectomy and 22 with non-anatomical hepatectomy.There were 18 patients undergoing regional lymph node dissection.The operation time of 62 patients was (217±86)minutes.Of 62 patients,12 had hepatic vascular occlusion using the Pringle method with a total occlusion time of (14±7)minutes,45 received selective hepatic vascular occlusion and 5 did not receive hepatic portal occlusion.The volume of intraoperative blood loss was 282 mL (range,20-2 500 mL).Four patients had intraoperative infusion of suspended red blood cells.The time for out-of-bed activity,time to initial anal exsufflation,time of abdominal drainage-tube removal,recovery time of liver function to normal level were 1 day (range,1-3 days),2.5 days (2.0-4.0 days),(4.4±1.3)days,(6.8±1.6) days.There was no liver failure.Six of 62 patients had postoperative complications,including 5 with thoracic and abdominal effusion,3 with abdominal infection,2 with pulmonary infection,2 with bile leakage,1 with intraperitoneal hemorrhage,1 with urinary retention,1 with postoperative incision infection,multiple complications might occur in the same patient.Two of 6 patients with complications of Clavien-Dindo Ⅲ were improved by symptomatic treatment.The other patients had no clear complications.The duration of postoperative hospital stay was (13±9) days.Thirteen patients received preventive TACE treatment after surgery,9 received 4-6 courses of chemotherapy,2 received both TACE and chemotherapy with chemotherapy drug of Tegafur or gemcitabine combined with cisplatin.(2) Pathological examination results:the tumor diameter of 62 patients was (5.4±3.3)cm,including 38 with the diameter ≤ 5 cm and 24 with the diameter ＞5 cm.There were 56 patients of mass-forming type,4 of intraductal growth type and 2 of periductal infiltrating type.High-,moderate-,poor-differentiated adenocarcinoma were respectively detected in 10,37 and 15 of 62 patients.The distance of surgical margins to tumor was ＞ 1.0 cm in 57 patients.There were 60 patients with negative surgical margin,1 patient of intraductal growth type and 1 of periductal infiltrating type with positive margin.Lymph node dissection was performed in 18 patients,among which 11 were pathologically positive,otherwise,there were 16 patients with microvascular invasion,and 4 patients with peripheral nerve infiltration.TNM stages of 62 patients:stage Ⅰ A,stage Ⅰ B,stage Ⅱ and stage ⅢB were respectively detected in 14,23,14 and11 patients.(3) Follow-up and survival situations:62 patients were followed up for (22± 12) months.The 1-and 3-year disease-free survival rates were 65.2％ and 39.8％ respectively.The 1-and 3-year overall survival rates were 89.6％ and 52.5％ respectively.During the follow-up,2 of 44 patients without lymph node dissection had liver portal lymph node metastasis,1 had extensive lymph node metastasis,2 died of other causes at 6 months and 18 months after operation.Conclusion Routine laparoscopic radical resection of intrahepatic cholangiocarcinoma with regional lymph node dissection is safe and effective,however,laparoscopic hepatectomy should be carefully selected for intraductal growth type and periductal infiltration type.

Objective To investigate the application value of three-dimensional (3D) reconstruction virtual surgery planning in the surgical treatment of hilar cholangiocarcinoma.Methods The retrospective crosssectional study was conducted.The clinical data of 36 patients with hilar cholangiocarcinoma who were admitted to the First Affiliated Hospital of Fujian Medical University between January 2014 and September 2017 was collected.Before operation,images of 3D virtual surgery planning were respectively reconstructed and determined using IQQA-Liver imaging analysis system,and then precise resection of tumor was performed based on results of virtual surgical planning and intraoperative conditions.Observation indicators:(1) virtual surgical planning;(2) surgical and postoperative situations;(3) follow-up and survival.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival and tumor recurrence or metastasis up to November 2017.Measurement data with normal distribution were represented as (x)±s.Comparison between indicator of preoperative virtual surgical planning and surgical indicators was analyzed by the t test.The postoperative survival time was calculated by the Kaplan-Meier method.Results (1) Virtual surgical planning:36 patients accomplished 3D visualization reconstruction and virtual surgical planning.Three D visualization reconstruction clearly showed adjacent relationship between tumor size and surrounding vessels or bile duct space.Type Ⅱ,Ⅲ a,Ⅲb and Ⅳ of Bismuth-Corlette Classification were detected in 2,13,14 and 7 patients by 3D visualization system,respectively.The tumor volume,whole liver volume,predicted liver resection volume and remnant liver volume were respectively (76± 26) mL,(1 319± 306) mL,(588± 128) mL and (731± 269) mL.(2) Surgical and postoperative situations:of 36 patients,16,12,5 and 3 patients underwent left hemigepatectomy,right hemigepatectomy,extended left hemigepatectomy and extended right hemigepatectomy,respectively,and all of them were combined with caudate lobectomy of liver.Combined resection and reconstruction of hepatic artery,combined wedge resection and repair of the portal vein and combined end-to-end anastomosis after resection of the portal vein were detected in 1,2 and 1 patients,respectively.Operation time and volume of intraoperative blood loss of 36 patients were respectively (368± 134)minutes and (474±288)mL.Thirty-six patients with postoperative complications were cured by conservative treatment,including 3 with pulmonary infection,3 with intra-abdominal infection and 2 with intra-abdominal lymphatic fistula.Duration of hospital stay of 36 patients was (19±7) days.Type Ⅱ,Ⅲ a,Ⅲ b and Ⅳ of postoperative Bismuth-Corlette Classification were detected in 2,11,13 and 10 patients,respectively.Accuracy of tumor classification through 3D visualization reconstruction was 91.7％ (33/36).Actual liver resection volume of 36 patients was (551± 141)mL,and was not significantly different from predicted liver resection volume (t =1.148,P＞0.05).(3) Follow-up and survival:31 of 36 patients were followed up for 2-39 months after surgery,with a median time of 16 months.The postoperative median survival time was 13 months,and 9 patients had tumor recurrence or metastasis during the follow-up.Conclusion The 3D reconstruction virtual surgery planning can accurately complete the preoperative evaluation,meanwhile,it can also provide important reference for the surgical therapy of hilar cholangiocarcinoma.

Three patients received surgical treatment in Department of Hepatobiliary Surgery of Mengchao Hepatobiliary Hospital from December 2020 to February 2022. Ceftriaxone sodium was given prophylactically before and after operation,and gallbladder silt stones were found by imaging examination on the 3rd, 3rd and 2nd after surgery in 3 patients, respectively. No special treatment was given,after the withdrawal of ceftriaxone sodium for 28, 38 and 48 d,radiographic examination showed that calculi disappeared spontaneously. It is suggested that the pseudolithiasis may be related to administration of ceftriaxone sodium.

Objective:To analyze and predict the clinical efficacy of rigid choledochoscopic percutaneous transhepatic biliary fistulation (PTBF) lithotripsy for the treatment of hepatolithiasis.Methods:Databases including PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang were searched for literatures from January 1, 1990 to March 1, 2022 on rigid choledochoscopic PTBF lithotripsy for hepatolithiasis studies. The primary outcomes including the final clearance rate, recurrence rate and overall postoperative complication rate, were analyzed by the random effects model in meta analysis and Bayesian network. The Markov Chain Monte Carlo was used for evaluation and prediction.Results:Fifteen articles were ultimately included, involving 1 296 patients, of which 1 008 patients were clearly shown to have complex intrahepatic bile duct stones in the literature [divided into two groups, the percutaneous transhepatic one-step biliary fistulation (PTOBF) stone removal group ( n=568) and the percutaneous transhepatic two-step biliary fistulation (PTTBF) stone removal group ( n=440)]. The results of Bayesian single-arm meta-analysis showed that the final clearance rate, recurrence rate and overall postoperative complication rate of PTOBF for hepatolithiasis were 84.19% (95% HPD: 79.08%-88.93%), 15.79% (95% HPD: 11.01%-21.07%) and 10.85% (95% HPD: 7.93%-14.21%). For complex hepatolithiasis, the final clearance rate, recurrence rate and overall postoperative complication rate of PTOBF were 82.58% (95% HPD: 75.46%-88.83%), 17.99% (95% HPD: 11.51%-25.45%), 10.34% (95% HPD: 6.42%-15.40%). For PTTBF, they were respectively 73.56% (95% HPD: 65.67%-80.30%), 29.48% (95% HPD: 23.13%-36.01%), 11.42% (95% HPD: 6.18%-17.67%). In comparison to PTTBF, the patients treated with PTOBF has a higher clearance rate ( OR=1.74, 95% CI: 1.17-2.60) and a lower recurrence rate ( OR=0.56, 95% CI: 0.37-0.84)but the overall complication rate did not improve ( OR=1.03, 95% CI: 0.66-1.62). Conclusions:Rigid choledochoscopic PTBF lithotripsy for hepatolithiasis is safe, effective and feasible. For complex hepatolithiasis, PTOBF has a higher clearance rate and a lower recurrence rate.

Objective To investigate the diagnostic value and clinical significance of hypersensitive C-reactive protein(hs-CRP),procalcitonin(PCT)combined with interleukin-6(IL-6)in children with severe hand-foot-mouth disease.Methods A total of 62 children hospitalized in our hospital from January 2022 to December 2022 were collected as research objects.According to the severity of infection,they were divided into observation group(severe infection group)with 29 cases and control group(mild infection group)with 33 cases.The differences of general data,total leukocyte count,neutrophil count,lymphocyte count,platelet count,hs-CRP,PCT,IL-6 and creatine kinase isoenzyme(CK-MB)between the two groups and their clinical applications were analyzed and compared.Results The total white blood cell count,neutrophil count,lymphocyte count,hs-CRP,PCT and IL-6 in the observation group were higher than those in the control group,and the difference has statistically significant.Receiver operator characteristic(ROC)curve analysis of hs-CRP predicted the sensitivity and specificity of severe infection of hand-foot-mouth disease were 79.3%and 93.9%(95%CI:0.852-10.985,P<0.05);The sensitivity and specificity of PCT were 93.1%and 84.8%(95%CI:0.907-1,P<0.05);The sensitivity and specificity of IL-6 were 96.6%and 87.9%(95%CI:0.945-1,P<0.05).Conclusions In hand-foot-mouth classification,PCT and IL-6 are highly sensitive.Although hs-CRP is less sensitive than the former,its specificity is higher than the former.Therefore,the combination of hs-CRP,PCT and IL-6 has higher value for hand-foot-mouth classification.
