Objective To provide the evidence for clinical medication safety by the investigation of the risk factors of linezolid-related thrombocytopenia in cancer patients in the department of hepatobiliary surgery. Methods Patients who received linezolid for anti-infective treatment from January 2017 to December 2021 were selected. The patients were divided into thrombocytopenia group and non-thrombocytopenia group according to whether thrombocytopenia occurred or not after administration of linezolid. The general data and laboratory indicators of the two groups were compared, and the risk factors of linezolid-related thrombocytopenia were screened by multivariate logistic regression analysis. Results A total of 104 patients were included in the study, including 84 patients who underwent surgery and 20 patients who did not. The incidence of linezolid-related thrombocytopenia was 24.0%. There were significant differences in gender, age, duration of linezolid use, platelet count, white blood cell count, alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin, creatinine, estimated glomerular filtration rate between the two groups (P<0.05); logistic regression analysis suggested that age ≥60 years (OR=7.093; P=0.017), duration of linezolid use ≥12 days (OR=4.399; P=0.035), baseline platelet count ≤200×109/L (OR=8.470; P=0.004), baseline AST≥50 U/L (OR=15.465; P<0.001), and baseline white blood cell count ≥11×109/L (OR=11.436; P=0.001) were the risk factors for linezolid-related thrombocytopenia in cancer patients. Conclusion During the treatment of linezolid in cancer patients, attention should be paid to the adverse reactions of thrombocytopenia in the patients, especially those with old age, long-term treatment, low baseline platelets, poor baseline liver function, and high baseline white blood cell counts.

Novel method of intraoperative liver tumour localisation with indocyanine green and near-infrared imaging

INTRODUCTION@#Fluorescence imaging (FI) with indocyanine green (ICG) is increasingly implemented as an intraoperative navigation tool in hepatobiliary surgery to identify hepatic tumours. This is useful in minimally invasive hepatectomy, where gross inspection and palpation are limited. This study aimed to evaluate the feasibility, safety and optimal timing of using ICG for tumour localisation in patients undergoing hepatic resection.@*METHODS@#From 2015 to 2018, a prospective multicentre study was conducted to evaluate feasibility and safety of ICG in tumour localisation following preoperative administration of ICG either on Day 0-3 or Day 4-7.@*RESULTS@#Among 32 patients, a total of 46 lesions were resected: 23 were hepatocellular carcinomas (HCCs), 12 were colorectal liver metastases (CRLM) and 11 were benign lesions. ICG FI identified 38 (82.6%) lesions prior to resection. The majority of HCCs were homogeneous fluorescing lesions (56.6%), while CLRM were homogeneous (41.7%) or rim-enhancing (33.3%). The majority (75.0%) of the lesions not detected by ICG FI were in cirrhotic livers. Most (84.1%) of ICG-positive lesions detected were < 1 cm deep, and half of the lesions ≥ 1 cm in depth were not detected. In cirrhotic patients with malignant lesions, those given ICG on preoperative Day 0-3 and Day 4-7 had detection rates of 66.7% and 91.7%, respectively. There were no adverse events.@*CONCLUSION@#ICG FI is a safe and feasible method to assist tumour localisation in liver surgery. Different tumours appear to display characteristic fluorescent patterns. There may be no disadvantage of administering ICG closer to the operative date if it is more convenient, except in patients with liver cirrhosis.

The outcome of endoscopic management of bile leakage after hepatobiliary surgery

BACKGROUND/AIMS: Despite improvements in surgical techniques and postoperative patient care, bile leakage can occur after hepatobiliary surgery and may lead to serious complications. The aim of this retrospective study was to evaluate the efficacy of endoscopic treatment of bile leakage after hepatobiliary surgery. METHODS: The medical records of 20 patients who underwent endoscopic retrograde cholangiopancreatography because of bile leakage after hepatobiliary surgery from August 2009 to September 2014 were reviewed retrospectively. Endoscopic treatment included insertion of an endoscopic retrograde biliary drainage stent after endoscopic sphincterotomy. RESULTS: Most cases of bile leakage presented as percutaneous bile drainage through a Jackson-Pratt bag (75%), followed by abdominal pain (20%). The sites of bile leaks were the cystic duct stump in 10 patients, intrahepatic ducts in five, liver beds in three, common hepatic duct in one, and common bile duct in one. Of the three cases of bile leakage combined with bile duct stricture, one patient had severe bile duct obstruction, and the others had mild strictures. Five cases of bile leakage also exhibited common bile duct stones. Concerning endoscopic modalities, endoscopic therapy for bile leakage was successful in 19 patients (95%). One patient experienced endoscopic failure because of an operation-induced bile duct deformity. One patient developed guidewire-induced microperforation during cannulation, which recovered with conservative treatment. One patient developed recurrent bile leakage, which required additional biliary stenting with sphincterotomy. CONCLUSIONS: The endoscopic approach should be considered a first-line modality for the diagnosis and treatment of bile leakage after hepatobiliary surgery.

The application of 3D printed model for precision medicine in hepatobiliary surgery / 中华肝胆外科杂志

The precise surgical treatment for hepatobiliary diseases has been a challenging topic in hepatobiliary surgery for a long time.A perfect preoperative plan can help the surgeon make R0 resection of the lesion and preserve the healthy tissue as much as possible.In addition,all of these depend on the application of different imaging modalities,especially three-dimensional reconstruction technique.But some limitations of 3D reconstruction should be noted:different surgeons may have different views for one object because of different observation points;or it cannot be used for intraoperative re-orientation and so on.3D printed model can overcome some disadvantages of 3D reconstruction.This paper reviewed related literature that reported the usage of 3D printed model in hepatobiliary surgery.
