High Arterial Lactate Levels after Hepatic Resection Are Associated with Low Oxygen Delivery and Predict Severe Postoperative Complications.

High End-Surgery Arterial Lactate Concentration (ES-ALC) predicts poor outcome after hepatectomy. The aim of this study was to identify intraoperative hemodynamic parameters predicting high ES-ALC during elective liver resection. Patients who underwent liver resection between 2017 and 2018, under FloTrac/EV1000TM hemodynamic monitoring, were included. The ES-ALC cutoff best predicting severe postoperative complications was identified. Association between high ES-ALC and preoperative and intraoperative variables was assessed. 108 patients were included; 90-day mortality was 0.9% and severe morbidity 14.8%. ES-ALC cutoff best discriminating severe complications was 5.05 mmol/L. Patients with ES-ALC > 5.0 mmol/L had a relative risk of severe complications of 2.8% (p = 0.004). High ES-ALC patients had longer surgery and ischemia duration, larger blood losses and higher requirements of fluids and blood transfusions. During surgery, hemoglobin concentration and oxygen delivery (DO2) decreased more significantly in patients with high ES-ALC, although they had similar values of stroke volume and cardiac output to those of other patients. At multivariate analysis, surgery duration and lowest recorded DO2 value were the strongest predictors of high ES-ALC. ES-ALC > 5.0 mmol/L in elective liver resection predicts postoperative morbidity and is essentially driven by the impaired DO2. Timely correction of blood losses might prevent the ES-ALC increase.

The impact of personalized nutritional support on postoperative outcome within the enhanced recovery after surgery (ERAS) program for liver resections: results from the NutriCatt protocol.

BACKGROUND: Malnutrition in liver surgery is correlated with higher postoperative complications and longer length of hospital stay (LOHS), the same items that ERAS programs try to optimize. However, to date, standardized dietary protocols have not been defined within ERAS programs. Aim of this study was to evaluate the impact on LOHS and postoperative complications, of a personalized nutritional protocol (NutriCatt) with diet and oral branched-chain amino acid (BCAA) supplementation, adopted within the ERAS program. METHODS: 1960 consecutive liver resections were performed from January 2000 to September 2018. EXCLUSION CRITERIA: perihilar cholangiocarcinoma, simultaneous colorectal and liver resections. Four groups for analysis: resections before 2009 (1st period); from 2009 to 2016 (2nd period, including laparoscopic resections); between 2016 and September 2017 (ERAS); after September 2017 (ERAS + NutriCatt). RESULTS: LOHS declined (p < 0.0001), from a median of 10 days (1st period) to 8, 7 and 6 in 2nd period, ERAS and ERAS + NutriCatt groups, respectively. At multivariable analysis for risk of LOHS > 8 days, the 2nd period, ERAS and ERAS + NutriCatt groups showed a protective effect. These results were confirmed for both minor and major resections. LOHS was significantly lower in ERAS + Nutricatt group than in ERAS group, without increasing risk of postoperative complications, although the rate of laparoscopic resections was similar in these two groups and complexity of liver resections was significantly higher in the last period. CONCLUSIONS: Adoption of a personalized nutritional protocol with BCAA supplementation within the ERAS program for liver resections was a safe and effective approach that may impact on reducing the LOHS.

The impact of R1 resection for colorectal liver metastases on local recurrence and overall survival in the era of modern chemotherapy: An analysis of 1,428 resection areas.

BACKGROUND: It is still unclear whether a positive surgical margin after resection of colorectal liver metastases remains a poor prognostic factor in the era of modern perioperative chemotherapy. The aim of this study was to evaluate whether preoperative chemotherapy has an impact on reducing local recurrence after R1 resection, and the impact of local recurrence on overall survival. METHODS: Between 2000 and 2014, a total of 421 patients underwent resection for colorectal liver metastases at our unit after preoperative chemotherapy. The overall number of analyzed resection areas was 1,428. RESULTS: The local recurrence rate was 12.8%, significantly higher after R1 resection than after R0 (24.5% vs 8.7%; P < .001). These results were also confirmed in patients with response to preoperative chemotherapy (23.1% after R1 vs 11.2% after R0; P < .001). At multivariate analysis, R1 resection was the only independent risk factor for local recurrence (P < .001). At the analysis of the 1,428 resection areas, local recurrence significantly decreased according to the increase of the surgical margin width (from 19.1% in 0 mm margin to 2.4% in ≥10 mm). At multivariable logistic regression analysis for overall survival, the presence of local recurrence showed a significant negative impact on 5-year overall survival (P < .001). CONCLUSION: Surgical margin recurrence after modern preoperative chemotherapy for colorectal liver metastases was still significantly higher after R1 resection than it was after R0 resection. Local recurrence showed a negative prognostic impact on overall survival. R0 resection should be recommended whenever technically achievable, as well as in patients treated by modern preoperative chemotherapy.

Facial pain: a possible therapy with stellate ganglion block.

OBJECTIVE: The goal of the present study is to verify the efficacy of stellate ganglion block (SGB) in the treatment of facial pain that can be found in different pathological syndromes, and also to examine whether the efficacy is dependent upon when this therapy is administered. PATIENTS: Fifty patients (divided into two randomized groups) with facial pain caused by traumas, iatrogenic issues, herpes zoster, or neurological pathologies participated in this study. DESIGN AND INTERVENTIONS: The first group (N = 25) was treated with SGB produced by 10 administrations of 10 mg of levobupivacaine given every other day, followed by one administration per month for 6 months thereafter. The second group was treated with the drugs tramadol 100 mg/day and gabapentin 1800 mg/day orally for 6 months; during the 7th month they were given SGB therapy using the same methodology as that described for the first group. RESULTS: Before treatment, the mean visual analog scale (VAS) pain score for the first group was 8.89; after the 10th block treatment it was just 0.2, and it remained at that reduced level for the 6th and 12th months. Before treatment, the mean VAS pain score for the second group was 8.83; after the 20th day on medication it was reduced to 4.1, after 6 months it was 5.7 and after 12 months it was 4.9. CONCLUSIONS: Our results indicate that patients must be treated with SGB therapy precociously to receive its full benefits.

A simplified way for the urgent treatment of somatic pain in patients admitted to the emergency room: the SUPER algorithm.

Somatic pain is one of the most frequent symptoms reported by patients presenting to the emergency department (ED), but, in spite of this, it is very often underestimated and under-treated. Moreover, pain-killers prescriptions are usually related to the medical examination, leading to a delay in its administration, thus worsening the patient's quality of life. With our study, we want to define and validate a systematic and homogeneous approach to analgesic drugs administration, testing a new therapeutic algorithm in terms of earliness, safety, and efficacy. 442 consecutive patients who accessed our ED for any kind of somatic pain were enrolled, and then randomly divided into two groups: group A follow the normal process of access to pain-control drugs, and group B follow our SUPER algorithm for early administration of drugs to relieve pain directly from triage. We excluded from the study, patients with abdominal pain referred to the surgeon, patients with headache, recent history of trauma, history of drug allergies, and life-threatening conditions or lack of cooperation. Drugs used in the study were those available in our ED, such as paracetamol, paracetamol/codeine, ketorolac-tromethamine, and tramadol-hydrochloride. Pain level, risk factors, indication, and contraindication of each drug were taken into account in our SUPER algorithm for a rapid and safe administration of it. The Verbal Numeric Scale (VNS) and the Visual Analog Scale (VAS) were used to verify the patient's health and perception of it. Only 59 patient from group A (27.1 %) received analgesic therapy (at the time of the medical examination) compared to 181 patients (100 %) of group B (p < 0.001). Group B patients, received analgesic therapy 76 min before group A subjects (p < 0.01), resulting in a significant lower VNS (7.31 ± 1.68 vs 4.75 ± 2.3; p < 0.001), and a superior VAS after discharge (54.43 ± 22.16 vs 61.30 ± 19.13; p < 0.001) compared to group A subjects. No significant differences concerning side effects were observed between group A and group B patients. Early administration of a pain-control therapy directly from triage is safe and effective, and significantly improves patients perceptions of their own health.
