Hepatobiliary Pancreat Dis Int 2023:S1499-3872(23)00244-8. [PMID: 38185585 DOI: 10.1016/j.hbpd.2023.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 11/01/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND In the overall surgical population, inadvertent perioperative hypothermia has been associated with an increased incidence of surgical site infection (SSI). However, recent clinical trials did not validate this notion. This study aimed to investigate the potential correlation between inadvertent perioperative hypothermia and SSIs following liver resection. METHODS This retrospective cohort study included all consecutive patients who underwent liver resection between January 2019 and December 2021 at the First Affiliated Hospital, Zhejiang University School of Medicine. Perioperative temperature managements were implemented for all patients included in the analysis. Estimated propensity score matching (PSM) was performed to reduce the baseline imbalances between the normothermia and hypothermia groups. Before and after PSM, univariate analyses were performed to evaluate the correlation between hypothermia and SSI. Multivariate regression analysis was performed to determine whether hypothermia was an independent risk factor for postoperative transfusion and major complications. Subgroup analyses were performed for diabetes mellitus, age > 65 years, and major liver resection. RESULTS Among 4000 patients, 2206 had hypothermia (55.2%), of which 150 developed SSI (6.8%). PSM yielded 1434 individuals in each group. After PSM, the hypothermia and normothermia groups demonstrated similar incidence rates of SSI (6.3% vs. 7.0%, P = 0.453), postoperative transfusion (13.3% vs. 13.7%, P = 0.743), and major complications (9.0% vs. 10.1%, P = 0.309). Univariate regression analysis revealed no significant effects of hypothermia on the incidence of SSI in the group with the highest hypothermia exposure [odds ratio (OR) = 1.25, 95% confidence interval (CI): 0.84-1.87, P = 0.266], the group with moderate exposure (OR = 1.00, 95% CI: 0.65-1.53, P = 0.999), or the group with the lowest exposure (OR = 1.11, 95% CI: 0.73-1.65, P = 0.628). The subgroup analysis revealed similar results. Regarding liver function, patients in the hypothermia group demonstrated lower γ-glutamyl transpeptidase (37 vs. 43 U/L, P = 0.001) and alkaline phosphatase (69 vs. 72 U/L, P = 0.016). However, patients in the hypothermia group exhibited prolonged activated partial thromboplastin time (29.2 vs. 28.6 s, P < 0.01). CONCLUSIONS In our study of patients undergoing liver resection, we found no significant association between mild perioperative hypothermia and SSI. It might be due to the perioperative temperature managements, especially active warming measures, which limited the impact of perioperative hypothermia on the occurrence of SSI.

Routine Postoperative Antibiotic Prophylaxis Offers No Benefit after Hepatectomy-A Systematic Review and Meta-Analysis. Antibiotics (Basel) 2022; 11:649. [PMID: 35625294 PMCID: PMC9138010 DOI: 10.3390/antibiotics11050649] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 05/09/2022] [Accepted: 05/10/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Prophylactic antibiotics are frequently administered after major abdominal surgery including hepatectomies aiming to prevent infective complications. Yet, excessive use of antibiotics increases resistance in bacteria. The aim of this systematic review and meta-analysis is to assess the efficacy of prophylactic antibiotics after hepatectomy (postoperative antibiotic prophylaxis, POA). METHOD This systematic review and meta-analysis were completed according to the current PRISMA guidelines. The protocol has been registered prior to data extraction (PROSPERO registration Nr: CRD42021288510). MEDLINE, Web of Science and CENTRAL were searched for clinical reports on POA in hepatectomy restrictions. A random-effects model was used for synthesis. Methodological quality was assessed with RoB2 and ROBINS-I. GRADE was used for the quality of evidence assessment. RESULTS Nine comparative studies comprising 2987 patients were identified: six randomized controlled trials (RCTs) and three retrospectives. POA did not lead to a reduction in postoperative infective complications or have an effect on liver-specific complications-post-hepatectomy liver failure and biliary leaks. POA over four or more days was associated with increased rates of deep surgical site infections compared to short-term administration for up to two days (OR 1.54; 95% CI [1.17;2.03]; p = 0.03). Routine POA led to significantly higher MRSA incidence as a pathogen (p = 0.0073). Overall, the risk of bias in the studies was low and the quality of evidence moderate. CONCLUSION Routine POA cannot be recommended after hepatectomy since it does not reduce postoperative infection or liver-specific complications but contributes to resistance in bacteria. Studies into individualized risk-adapted antibiotic prophylaxis strategies are needed to further optimize perioperative treatment in liver surgery.

Population Pharmacokinetic-Pharmacodynamic Target Attainment Analysis of Flomoxef in the Serum and Liver Tissue of Patients Undergoing Hepatic Resection. Antimicrob Agents Chemother 2022; 66:e0230321. [PMID: 35306834 DOI: 10.1128/aac.02303-21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
The purpose of this study was to investigate the population pharmacokinetics of prophylactic flomoxef based on serum and liver tissue concentrations and to demonstrate a pharmacodynamic target concentration in the serum and liver tissue exceeding the MIC in order to design an effective dosing regimen. Serum samples (n = 210) and liver tissue samples (n = 29) from 43 individuals were analyzed using a nonlinear mixed-effects model. The pharmacodynamics index target value was regarded as the probability of maintaining flomoxef serum trough and liver tissue concentrations exceeding the MIC90 values, 0.5 mg/L and 1.0 mg/L, for Escherichia coli and methicillin-susceptible Staphylococcus aureus, respectively. The final population pharmacokinetic model was a two-compartment model with linear elimination. Creatinine clearance (CLCR) was identified as a significant covariate influencing total clearance when CLCR was less than 60 mL/min. The probability of achieving concentrations in the serum and liver tissue exceeding the MIC90 for E. coli or methicillin-susceptible S. aureus for a 1 g bolus dose was above 90% at 2 h after the initial dose. Our findings suggest that population pharmacokinetic parameters are helpful for evaluating flomoxef pharmacokinetics and determining intraoperative flomoxef redosing intervals.

Antibiotic Prophylaxis for Hepato-Biliopancreatic Surgery—A Systematic Review. Antibiotics (Basel) 2022; 11:antibiotics11020194.

Abstract
Background: Surgical site infections (SSIs) are among the most important determinants of morbidity after HBP surgery. Their frequency after HPB surgery is variable, from 1–2% after elective cholecystectomy to 25% after PD. Methods: A systematic review was performed to assess the role of antimicrobial prophylaxis (AP) in HPB elective surgery. Articles published between 2015 and 2021 were obtained; those before 2015 were not included because they antedate the WHO guidelines on SSI prevention. We conducted three different research methods for liver resection, elective cholecystectomy and pancreatic and biliary surgery regarding patients requiring preoperative biliary drainage. Results: Hepatic surgery, improvement in surgical technique and perioperative management lead to a very low SSI. One preoperative 2 g cefazolin dose may be adequate for surgical prophylaxis. From preoperative biliary drainage, we can derive that patients’ homeostasis rather than AP plays a paramount role in reducing postoperative morbidity. The time from biliary drainage could be an essential element in decision making for surgical prophylaxis. In the case of low-risk cholecystectomy, it is not easy to draw definitive conclusions about the effect of AP. Data from the literature are inconsistent, and some risk factors cannot be predicted before surgery. Conclusion: in our opinion, a strict preoperative cefazolin dose strategy can be reasonable in HBP surgery until a large-scale, multicentric RCT brings definitive conclusions.

Abstract
Hepatocellular carcinoma is often accompanied by chronic hepatitis or cirrhosis. Preoperative evaluation of liver function and postoperative nutritional management are critical in patients with hepatocellular carcinoma who undergo liver surgery. Although the incidence of postoperative complications and death has declined in Japan over the last 10 years, postoperative complications have not been fully overcome. Therefore, surgical procedures and perioperative management must be improved. Accurate preoperative evaluations of liver function, nutrition, inflammation, and body skeletal muscle are required. Determination of the optimal surgical procedure should consider not only tumor characteristics but also the physical reserve of the patient. Nutritional management of chronic liver disorders, especially maintaining protein synthesis for postoperative protein/energy, is important. Prophylactic antibiotics are recommended for short‐term use within 24 hours after surgery. Abdominal drainage is recommended for patients with cirrhosis who may develop large amounts of ascites, who are at risk of postoperative bleeding, or who may have bile leakage due to a large resection area. Postoperative exercise therapy may improve insulin resistance in patients with chronic liver damage. Implementation of an early/enhanced recovery after surgery program is recommended to reduce biological invasive responses and achieve early independence of physical activity and nutrition intake. We review the latest information on the perioperative management of patients undergoing liver resection for hepatocellular carcinoma.

Abstract
INTRODUCTION The duration of perioperative antibiotic prophylaxis following live liver donor hepatectomy (LDH) is not known. METHODS This is a double-blind equivalence trial. All consecutive LDH were randomized into: group A (three doses) and group B (nine doses) of perioperative antibiotics (piperacillin + tazobactam - 4.5 g intravenous) at fixed 8 hourly intervals. Primary end point was incidence of infective complications as per CDC (Centers for Disease Control and Prevention) criteria. Secondary end points were liver function tests, total leukocyte count, international normalized ratio, hospital stay, morbidity, and cost analysis. RESULTS One hundred and twenty-six LDHs were enrolled. A total of 19.8% (n = 25) experienced postoperative complications, 11 (17.7%) in group A and 14 (21.9%) in group B (P = .561). Infective complications were seen in 11 donors (8.1%), five in group A and six in group B (P = .79). A total of 8.1% of donors required continuation/up-gradation of antibiotics in group A and 9.4% in group B. Return to soft diet was delayed in group B (P = .039). Median hospital stay and cost were similar. CONCLUSION Three doses of perioperative antibiotic are equally effective in preventing infective complications.

Abstract
BACKGROUND Despite the recently increasing number of elderly patients undergoing liver resection, the impact of advancing age on postoperative infections (PIs) incidence and risk remains unclear. This study aimed to investigate the impact of advancing age on PIs incidence and status. METHODS This retrospective study included 744 patients undergoing liver resection without biliary reconstruction or combined resection of other organs. Multivariable analysis with a restricted cubic spline was used to evaluate the impact of advancing age on PIs and to determine its association with PIs risk in patients undergoing open and laparoscopic liver resection (OLR and LLR, respectively). RESULTS Multivariable analysis demonstrated that advancing age was significantly associated with increased PIs risk (P = 0.017). The spline curve showed that the odds ratio for PIs sharply increased starting approximately at 65 years of age. Unadjusted restricted cubic splines assessing the subcategories of PIs demonstrated that advancing age was associated with increased risks of organ/space surgical site infection and sepsis (P = 0,064 and 0.048, respectively). Multivariable analysis revealed that LLR was associated with the lower PIs risk compared with OLR (P = 0.025), whereas the lower PIs risk with LLR was not significantly obscured by advancing age (P = 0.29). CONCLUSIONS Advancing age was associated with increased risk of PIs, including organ/space surgical site infections and sepsis, after liver resection especially in patients aged ≥ 65 years.

Abstract
(1) Background: Anaerobic infections in hepatobiliary surgery have rarely been addressed. Whereas infectious complications during the perioperative phase of liver resections are common, there are very limited data on the prevalence and clinical role of anaerobes in this context. Given the risk of contaminated bile in liver resections, the goal of our study was to investigate the prevalence and outcome of anaerobic infections in major hepatectomies. (2) Methods: We retrospectively analyzed the charts of 245 consecutive major hepatectomies that were performed at the department of General, Visceral, and Transplantation Surgery of the University Hospital of Tuebingen between July 2017 and August 2020. All microbiological cultures were screened for the prevalence of anaerobic bacteria and the patients' clinical characteristics and outcomes were evaluated. (3) Results: Of the 245 patients, 13 patients suffered from anaerobic infections. Seven had positive cultures from the biliary tract during the primary procedure, while six had positive culture results from samples obtained during the management of complications. Risk factors for anaerobic infections were preoperative biliary stenting (p = 0.002) and bile leaks (p = 0.009). All of these infections had to be treated by intervention and adjunct antibiotic treatment with broad spectrum antibiotics. (4) Conclusions: Anaerobic infections are rare in liver resections. Certain risk factors trigger the antibiotic coverage of anaerobes.

Abstract
BACKGROUND Laparoscopic liver resection is beneficial compared to open liver resection. This study aimed to evaluate whether laparoscopic liver resection could reduce postoperative infections. METHODS This study included 125 and 115 patients with liver tumors who underwent open and pure laparoscopic partial resections or left lateral sectionectomies, respectively. Propensity score matching and stabilized inverse probability of treatment weighting were carried out to compare the postoperative infectious complication rates between the two groups. RESULTS Patients with tumors located in Couinaud segment 1, 7, or 8; with tumors adjacent to major vessels; or who underwent repeated resections were more likely to receive open resection. After propensity score matching, the superficial incisional surgical site infection rate tended to be lower in the laparoscopic liver resection group than in the open liver resection group. Moreover, overall infectious complication rate and superficial incisional surgical site infection rate were lower in the laparoscopic group (the cohort formed by the stabilized inverse probability of treatment weighting). CONCLUSIONS Using the laparoscopic approach for partial resections and left lateral sectionectomies for liver tumors, the superficial incisional surgical site infection rate could be reduced.
