Surgical clearance for the patient with chronic liver disease

Decreased Length of Stay and Opioid Usage After Liver Cancer Surgery With Enhanced Recovery Pathway Implementation

BACKGROUND AND OBJECTIVES

Enhanced recovery after surgery (ERAS) pathways are associated with better postoperative recovery; however, evidence is lacking in liver cancer surgery. This study aimed to evaluate the impact of an ERAS pathway in US veterans undergoing liver cancer surgery.

METHODS

We initiated an ERAS pathway for liver cancer surgery with preoperative, intraoperative, and postoperative interventions, which included a novel regional anesthesia technique, erector spinae plane block, for multimodal analgesia management. A retrospective quality improvement study was conducted with patients undergoing elective open hepatectomy or microwave ablation of liver tumors before and after ERAS pathway implementation.

RESULTS

With 24 patients in the post-ERAS group and 23 patients in the pre-ERAS group, we found a significant decreased length of stay in the ERAS group (4.1 days ± 3.9) compared with traditional care (8.6 days ± 7.1, P = .01) and decreased perioperative opioid consumption including intraoperative opioids (post-ERAS 49.8 mg ± 28.5 vs pre-ERAS 98 mg ± 42.3, P = 4.1E-5), postoperative opioids (post-ERAS 65.3 mg ± 59.9 vs pre-ERAS 175.7 mg ± 210.6, P = .018), and patient-controlled analgesia requirements (post-ERAS 0% vs pre-ERAS 50%, P < .001).

CONCLUSION

The implementation of ERAS for liver cancer surgery in our veteran population translates into decreased length of stay and perioperative opioid consumption. Although this study is limited as a quality improvement project implemented at one institution with a small sample size, our results are clinically and statistically significant and sufficient to warrant further investigation into the efficacy of ERAS as the surgical needs of the US veteran population increase.

Bariatric Surgery in Cirrhotic Patients: a Matched Case-Control Study

INTRODUCTION

Laparoscopic bariatric surgery (LBS) in liver end-stage organ disease has been proven to improve organ function and patients' symptoms. A series of LBS in patients with cirrhosis have shown good results in weight loss, but increased risk of complications. Current literature is based on clinical series. This paper aims to compare LBS (69% gastric bypass) between patients with cirrhosis and without cirrhosis.

METHODS

We conducted a retrospective 1:3 matched case-control study including bariatric patients with cirrhosis and without cirrhosis. Demographics, operative variables, postoperative complications, long-term weight loss, and comorbidity resolution were compared between groups.

RESULTS

Sixteen Child A patients were included in the patients with cirrhosis (PC) group and 48 in patients without cirrhosis (control) group. Mean age was 50 years; preoperative BMI was 39 ± 6.8 kg/m². Laparoscopic gastric bypass and laparoscopic sleeve gastrectomy were performed in 69% and 31%, respectively. Follow-up was 81% at 2 years for both groups. PC group had a higher rate of overall (31% vs. 6%; p < 0.05) and severe (Clavien-Dindo ≥ III; 13% vs. 0%; p = 0.013) complications than that of the control group. Mean %EWL of PC at 2 years of follow-up was 84.9%, without differences compared with that of the control group (83.1%). Comorbidity remission in PC was 14%, 50%, and 85% for hypertension, type 2 diabetes, and dyslipidemia, respectively. Patients without cirrhosis had a higher resolution rate of hypertension (65% vs. 14%, p = 0.03).

CONCLUSION

LBS is effective for weight loss and comorbidity resolution in patients with obesity and Child A liver cirrhosis. However, these results are accompanied by significantly increased risk of complications.

Postoperative Risk of Hepatic Decompensation after Orthopedic Surgery in Patients with Cirrhosis

BACKGROUND AND AIMS

Previous studies have shown increased hepatic decompensation in patients with cirrhosis undergoing surgery. However, there are little data available in cirrhotics undergoing orthopedic surgery compared to cirrhotics who did not undergo surgery. The aim of this study was to examine the demographics, comorbid conditions, and clinical factors associated with hepatic decompensation within 90 days in cirrhotics who underwent orthopedic surgery.

METHODS

This is a retrospective matched cohort study. Inclusion criteria were cirrhosis diagnosis, age > 18 years, ≥ 6 months continuous health plan membership, and a procedure code for orthopedic surgery. Up to five cirrhotic controls without orthopedic surgery were matched on age, gender, and cirrhosis diagnosis date. Data abstraction was performed for demographics, socioeconomics, clinical, and decompensation data. Chart review was performed for validation. Multivariable analysis estimated relative risk of decompensation.

RESULTS

Eight hundred fifty-three orthopedic surgery cases in cirrhotics were matched with 4,263 cirrhotic controls. Among the cases and matched controls, the mean age was 60.5 years, and 52.2% were female. Within 90 days after surgery, cases had more decompensation compared to matched controls (12.8% vs 4.9%). Using multivariable analysis, orthopedic surgery, a 0.5 g/dL decrease in serum albumin, and a 1-unit increase in Charlson Comorbidity Index were associated with a significant increase in decompensation within 90 days of surgery. Diabetes, chronic obstructive pulmonary disease, and chronic kidney disease were seen with increased frequency in cases vs. matched controls.

CONCLUSIONS

Cirrhotics who underwent orthopedic surgery had a significant increase in hepatic decompensation within 90 days of surgery compared to matched controls. An incremental decrease in serum albumin and an incremental increase in the Charlson Comorbidity Index were significantly associated with hepatic decompensation after surgery.

Preoperative embolization for bone metastasis from hepatocellular carcinoma

Preoperative transcatheter arterial embolization for hypervascular bone tumors is now widely accepted as a safe and effective procedure for reducing intraoperative blood loss and surgical morbidity. However, few studies have reported the use of preoperative transcatheter arterial embolization for nonspine bone metastases from hepatocellular carcinoma. The goal of this study was to assess the effect of preoperative embolization on blood loss and clinical outcomes in surgery for nonspine bone metastasis from hepatocellular carcinoma. Seventy-five patients with metastases from hepatocellular carcinoma to the pelvis and extremities were reviewed retrospectively. The study population consisted of 62 men and 13 women, with a mean age of 64.6 years (range, 40.0-80.1). The average follow-up period was 8.2 months (range, 0.3-66.1). Twenty-two patients underwent transcatheter arterial embolization for preoperative devascularization (group A), and 53 patients underwent operative treatment only (group B). The proportion of pelvis metastases was significantly higher (P<.001) and operative time was longer (P=.006) in group A than in group B. However, a significantly smaller decrease in hemoglobin level before and after surgery was seen in group A (P=.017). No significant differences were seen in intraoperative estimated blood loss, perioperative hemoglobin level, number of allogeneic transfusions, or length of hospitalization between the 2 groups. Preoperative transcatheter arterial embolization is an effective means to reduce bleeding during surgery for nonspine metastases from hepatocellular carcinoma. In general, surgical procedures that included transcatheter arterial embolization took longer and were more extensive.

Correlation between standard remnant liver volume and liver function decompensation in patients after surgery for hepatocellular carcinoma

AIM: To investigate the correlation between standard remnant liver volume and liver function decompensation in patients after surgery for hepatocellular carcinoma.

METHODS: A total of 80 cases of hepatocellular carcinoma in patients with cirrhosis were retrospectively analyzed. According to the ratio of the size of the remnant liver volume after resection, patients were divided into two groups: a small resection (SR) group and a large resection (LR) group. The liver function, tumor markers and postoperative outcome of these two groups were compared before and after the surgery.

RESULTS: The total bilirubin (TB), international normalized ratio (INR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) increased significantly after surgery (P < 0.05). Postoperative TB, INR, AST in the LR group were higher than those in the SR group, and ALT on days 5 and 7 was significantly higher in the LR group than in the SR group (P < 0.05). α-fetoprotein (AFP) and CA19-9 significantly decreased after surgery (P < 0.05). Postoperative AFP in the LR group was significantly higher than that in the SR group (P < 0.05). The incidence of hepatic decompensation and hepatic failure in the LR group was higher than that in the SR group (25.0% vs 3.3%, 12.0% vs 0%, P < 0.05 for both), although the incidence of wound infection, portal vein thrombosis and intra-abdominal hemorrhage did not differ between the two groups.

CONCLUSION: Standard remnant liver volume is a good indicator of liver reserve function in patients with hepatocellular carcinoma after operation, and patients with greater standard remnant liver volume has a lower incidence of liver function decompensation and hepatic failure.

Surgery in patients with portal hypertension: a preoperative checklist and strategies for attenuating risk

Patients with liver disease and portal hypertension are at increased risk of complications from surgery. Recent advances have allowed better optimization of patients with cirrhosis before surgery and a reduction in postoperative complications. Despite this progress, the estimation of surgical risk in a patient with cirrhosis is challenging. The MELD score has shown promise in predicting postoperative mortality compared with the Child-Turcotte-Pugh score. This article addresses current concepts in the perioperative evaluation of patients with liver disease and portal tension, including a preoperative liver assessment (POLA) checklist that may be useful towards mitigating perioperative complications.
