Laparoscopic treatment of biliary peritonitis following nonoperative management of blunt liver trauma
<p>Abstract</p> <p>Introduction</p> <p>Nonoperative management (NOM) of hemodynamically stable patients with blunt hepatic injuries is considered the current standard of care. However, it is associated with several in-hospital complications. In selected cases laparoscopy could be proposed as diagnostic and therapeutic means.</p> <p>Case report</p> <p>A 28 years-old male was admitted in the Emergency Unit following a motor vehicle crash. CT-scan showed an isolated stade II hepatic injury at the level of the segment IV. Firstly a NOM was decided. Laparoscopic exploration was then performed at day 4 due to a biliary peritonitis. Intraoperative trans-cystic duct cholangiography showed a biliary leaks of left hepatic biliary tract, involving sectioral pedicle to segment III. Cholecystectomy, trans-cystic biliary drainage, application of surgical tissue sealing patch and abdominal drainage were performed. Postoperative outcome was uneventful, with fast patient recovery.</p> <p>Conclusion</p> <p>Laparoscopy has gained a role as diagnostic and therapeutic means in treatment of complications following NOM of blunt liver trauma. This approach seems feasible and safety, with satisfactory postoperative outcome.</p

Despite a large body of evidence, the implementation of guidelines on hemodynamic optimization and goal-directed therapy remains limited in daily routine practice. To facilitate/accelerate this implementation, a panel of experts in the field proposes an approach based on six relevant questions/answers that are frequently mentioned by clinicians, using a critical appraisal of the literature and a modified Delphi process. The mean arterial pressure is a major determinant of organ perfusion, so that the authors unanimously recommend not to tolerate absolute values below 65Â mmHg during surgery to reduce the risk of postoperative organ dysfunction. Despite well-identified limitations, the authors unanimously propose the use of dynamic indices to rationalize fluid therapy in a large number of patients undergoing non-cardiac surgery, pending the implementation of a "validity criteria checklist" before applying volume expansion. The authors recommend with a good agreement mini- or non-invasive stroke volume/cardiac output monitoring in moderate to high-risk surgical patients to optimize fluid therapy on an individual basis and avoid volume overload. The authors propose to use fluids and vasoconstrictors in combination to achieve optimal blood flow and maintain perfusion pressure above the thresholds considered at risk. Although purchase of disposable sensors and stand-alone monitors will result in additional costs, the authors unanimously acknowledge that there are data strongly suggesting this may be counterbalanced by a sustained reduction in postoperative morbidity and hospital lengths of stay. Beside existing guidelines, knowledge and explicit clinical reasoning tools followed by decision algorithms are mandatory to implement individualized hemodynamic optimization strategies and reduce postoperative morbidity and duration of hospital stay in high-risk surgical patients
Quality of life of patients with hip fracture was better during the COVID-19 period than before, an ancillary study from the HiFIT multicenter study
BackgroundThe COVID-19 pandemic had a global impact on people life, notably because of lockdown periods. This could particularly affected patients suffering from hip fracture, who could have been more isolated during these periods. We aim at evaluating the impact of the COVID-19 period (including lockdown periods) on quality of life (QOL) in older adult patients 90âdays after a surgery for a hip fracture.Subject and methodsAncillary study of the prospective randomized controlled HiFIT study. We compared the QOL measured at 90âdays after a hip fracture surgery using the EuroQOL-5 dimensions 3 levels (EQ-5D), the Perceived Quality of life (PQOL) and the Instrumental Activities of Daily Living (IADL) in patients included in the Hifit study before and during the COVID-19 pandemic.ResultsThe characteristics of the 161 patients included before and of the 213 included during the COVID period (including 122 (57%) during COVID with containment periods and 91 (43%) during COVID without containment periods) were similar (mean age 84â±â10âyears; 282 (75%) women). The majority (81%) of the patients alive at 90âdays had returned to their previous place of residence in both periods. During the COVID period, EQ-5D showed better patient pain/discomfort and anxiety/depression levels. The PQOL happiness was not different, with around 81% of the patient being âhappyâ or âvery happyâ during the two periods and the IADL was also similar during the two periods. In the multivariate analysis odd ratios of having poorer outcomes were increased before COVID for pain/discomfort (OR 2.38, 95%CI [1.41â4.15], pâ=â0.001), anxiety (OR 1.89 [1.12â3.21], pâ=â0.017) and mobility (1.69 [1.02â2.86], pâ=â0.044).ConclusionPatientâs quality of life measured using different scales was not altered during the COVID period compared to before COVID, 90âdays after a hip fracture. Surprisingly, the Pain/Discomfort and Anxiety dimensions of the EQ-5D questionnaires were even better during the COVID period.Clinical trial registration:https://clinicaltrials.gov/ (NCT02972294)

Lactate, mitochondria, compartmentalization and chronology of inflammatory response after gut ischemia reperfusion
LâischĂ©mie reperfusion intestinale (IR-I) est souvent prĂ©sentĂ©e comme Ă©tant la principale source de lâhyperlactatĂ©mie et comme le moteur de la rĂ©ponse inflammatoire lors des Ă©tats de choc et de la dĂ©faillance multiviscĂ©rale. NĂ©anmoins, peu dâĂ©tudes sâintĂ©ressent Ă comprendre lâorigine de lâhyperlactatĂ©mie et de la rĂ©ponse inflammatoire pendant la phase de reperfusion intestinale ainsi que le rĂŽle de la mitochondrie dans la survenue des dysfonctions dâorgane Ă distance de lâIR - I.

La lactatĂ©mie capillaire semble ĂȘtre un outil diagnostique maniable et fiable. Par contre, le D-lactate ne semble pas ĂȘtre un marqueur biologique sensible de lâIR-I. Enfin, lâisoflurane et le bleu de mĂ©thylĂšne, dĂ©jĂ utilisĂ©s en pratique clinique, protĂšgent les mitochondries dâorganes situĂ©s Ă distance de lâischĂ©mie reperfusion intestinale comme le foie et les poumons.

However, few studies focus on the origin of hyperlactatemia and inflammatory response during gut reperfusion and on the role of mitochondria in the development of organ dysfunction.Our work aims to better understand the mechanisms of G-IR, seek for diagnostics and provide therapeutic.Our work provides evidence for a better understanding of many aspects of the G-IR. It presents new evidence of pathophysiology, proposes the development of capillary blood lactate as a diagnostic tool and suggests therapeutic solutions to limit the deleterious effects of G-IR.Specifically, we observe that G-IR associated local lesions, compartmentalized systemic inflammatory response and remotely early mitochondrial dysfunction and apoptosis. The capillary lactate seems to be a handy and reliable diagnostic tool. D-lactate does not appear to be a sensitive biomarker of G-IR. Finally, isoflurane and methylene blue, already used in clinical practice, protect mitochondria of remote organs such as liver and lung.

IntĂ©rĂȘt du d-lactate dans le diagnostic des ischĂ©mies coliques aprĂšs chirurgie de l'aorte abdominale
Le d-lactate est la forme dextrogyre du lactate dosĂ© habituellement en rĂ©animation. I1 n'est produit que par le mĂ©tabolisme bactĂ©rien et a Ă©tĂ© rĂ©cemment proposĂ© comme marqueur de la translocation lors des ischĂ©mies digestives. La chirurgie de l'aorte nĂ©cessite un clampage artĂ©riel pouvant se compliquer d'une ischĂ©mie colique souvent rĂ©vĂ©lĂ©e par un Ă©tat de choc. Le but de cette Ă©tude Ă©tait donc d'Ă©valuer l'intĂ©rĂȘt de ce dosage dans le diagnostic prĂ©coce de l'ischĂ©mie en postopĂ©ratoire de la chirurgie aortique en comparant les taux de d-lactate aux donnĂ©es cliniques. MatĂ©riel et mĂ©thode : 3 groupes de malades ont Ă©tĂ© formĂ©s, groupe 1: malades opĂ©rĂ©s de l'aorte, groupe 2 : malades hospitalisĂ©s en rĂ©animation non opĂ©rĂ©s de l'aorte et associant au moins deux dĂ©faillances viscĂ©rales, groupe3 : tĂ©moins sains. RĂ©sultats : de janvier Ă juin 2000, 51 sujets ont Ă©tĂ© prĂ©levĂ©s pour le dosage du d-lactate : 10 tĂ©moins sains, 29 malades opĂ©rĂ©s de l'aorte et 12 malades pour le groupe 2. Le d-lactate augmente significativement (p<0,01) dans le groupe 1 lorsque le chirurgien constate une hypoperfusion du colon en peropĂ©ratoire (pression d'occlusion de l'artĂšre mĂ©sentĂ©rique infĂ©rieure Ă 40 mmHg). La d lac;tatĂ©mie est aussi augmentĂ©e en cas d'Ă©tat de choc (p<0,(101) ou d'insuffisance rĂ©nale w<0,02). Pour chaque rĂ©sultat significatif, le taux moyen retrouvĂ© est supĂ©rieur au seuil retenu dans la littĂ©rature (0.20mmol/l) pour dĂ©finir le risque d'ischĂ©mie digestive (seuil de sensibilitĂ© de notre dosage : 0,14 mmol/l). Conclusion : ces donnĂ©es semblent confirmer la place du d-lactate dans le diagnostic prĂ©coce de la souffrance colique, aprĂšs clampage de l'aorte abdominale ou lors de l'Ă©tat de choc . Ces donnĂ©es doivent ĂȘtre confirmĂ©es dans une Ă©tude de plus grande envergure.ROUEN-BU MĂ©decine-Pharmacie (765402102) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF
