Microvascular myocutaneous and cutaneous free flap reconstruction in patients with terminal esophagostomy after complicated oncological esophagus resection

Summary Background Persisting anastomotic leakage after oncological esophagectomy is a severe problem associated with high mortality and morbidity. Unfortunately, treatment options with promising results are scarce, especially when conventional operative and endoscopic methods have failed. Due to limitation of oral intake and the need for artificial nutrition, quality of life (QOL) is reduced. Microvascular myocutaneous and cutaneous free flap (MFF) reconstruction could be a promising alternative. Methods This retrospective case series presents 7 patients treated between March 2017 and November 2020 at our surgical department, with persisting postoperative anastomotic leakage without further feasible treatment options. All patients received anastomotic MFF reconstruction; used flaps and important intraoperative factors like microvascular anastomosis were evaluated. Complications and patient contentment was assessed. Results The included 7 male patients had median age of 65.15 years (range: 48–75). MFF function was adequate in 6/7 patients, one flap necrosis was encountered. Whereas 5 patients initially had good results, surgical revision was performed in 1 patient to ensure graft function. Postoperative complications appeared in 6/7 patients. Mean duration of inpatient care was 63 days (range: 24–156). At the time of evaluation, 1 patient has died of his malignant disease. No more additional nutrition was needed in 3/6 patients with adequate graft function. Most patients reported improved QOL after MFF. Conclusion MFF free flap can be an alternative treatment option for patients with terminal esophagostomy after complicated oncological esophagus resection without further treatment options. The renewed ability of oral food intake results in a significant improvement of QOL.

Do we need a 6D’s Framework of Nutritional Stewardship in critical care?

Recent European Society for Clinical Nutrition and Metabolism (ESPEN) guideline on clinical nutrition in the intensive care unit had as ultimate goal the achievement of optimal nutritional support for critically ill patients and to illuminate the gaps in knowledge in order to provide priorities for future clinical research. Although malnutrition is a vital part of the treatment of patients with critical illness and injury, nutrition in the critically ill is not one size fits all. Both clinical nutrition guidelines and ICU experts have recognized the need for a new, individualized approach to nutrition. Nutrition stewardship, analog to antimicrobial and fluid stewardship, could be defined as the “ongoing effort by a healthcare institution to optimise artificial nutrition use in order to improve patient outcomes, ensure cost effective therapy and reduce adverse sequelae.” A robust nutrition stewardship program could gain reputation if the concept will spread to various national programs and regulatory guidelines released in the recent past.

Relationship Between Nutrition Intake and Outcome After Subarachnoid Hemorrhage: Results From the International Nutritional Survey

Background: A previous study suggested an association between low caloric intake(CI), negative nitrogen balance, and poor outcome after subarachnoid hemorrhage(SAH). Objective of this multinational, multicenter study was to investigate whether clinical outcomes vary by protein intake(PI) or CI in SAH patients adjusting for the nutritional risk as judged by the modified NUTrition Risk in the Critically Ill (mNUTRIC) score. Methods: The International Nutrition Survey(INS) 2007-2014 was utilized to describe the characteristics, outcomes and nutrition use. A subgroup of patients from 2013 and 2014(when NUTRIC score was captured) examined the association between CI and PI and time to discharge alive(TTDA) from hospital using Cox regression models, adjusting for nutrition risk classified by the mNUTRIC score as low(0-4) or high(5-9). Results: There were 489 SAH patients(57% female with a mean ± SD age 57.5 ± 13.9 years, BMI of 25.9 ± 5.3 kg/m2 and APACHE-2 score 19.4 ± 7.0. Majority(85%) received enteral nutrition(EN) only, with a time to initiation of EN of 35.4 ± 35.2 hours. 64% had EN interrupted. Patients received a CI of 14.6 ± 7.1 calories/kg/day and PI 0.7 ± 0.3 grams/kg/day corresponding to 59% and 55% of total prescribed CI and PI respectively. In the 2013 and 2014 subgroup there were 226 SAH patients with a mNUTRIC score of 3.4 ± 1.8. Increased CI and PI were associated with faster TTDA among high mNUTRIC patients(HR per 20% of prescription received = 1.34[95% CI,1.03 -1.76] for CI and 1.44[1.07 -1.93] for PI), but not low mNUTRIC patients(CI: HR = 0.95[0.77 -1.16] PI:0.95[0.78 -1.16]). Conclusions: Results from this multicenter study found that SAH patients received under 60% of their prescribed CI and PI. Further, achieving greater CI and PI in hi risk SAH patients was associated with improved TTDA. mNUTRIC serves to identify SAH patients that benefit most from artificial nutrition and efforts to optimize protein and caloric delivery in this subpopulation should be maximized.

Buried bumper syndrome: prevention and management in the community

Percutaneous endoscopic gastrostomy (PEG) is a well-established form of artificial nutrition. Buried bumper syndrome (BBS) is a rare but severe complication related to this type of feeding tube. BBS is described as when the internal bumper migrates into the stoma tract and/or the mucosa, and the inner lining of the stomach starts to grow around and over the internal bumper. It can result in pain, infection and the loss of the feeding tube as a port of entry for delivery of nutrition, hydration and medication into the stomach. When suspected, BBS requires urgent referral into specialist hospital services. It is somewhat preventable with appropriate aftercare; however, incidents do occur. The evidence and guidance on care of PEGs differs, and more data and research are needed into the incidence of BBS and what influences it. Access to appropriate nutrition support teams is essential to support patients and their caregivers with all aspects of enteral feeding.

662 MICROVASCULAR MYOCUTANEOUS AND CUTANEOUS FREE FLAP RECONSTRUCTION FOR PATIENTS WITH TERMINAL ESOPHAGOSTOMY AFTER COMPLICATED ONCOLOGICAL ESOPHAGUS RESECTION

Persisting anastomotic leak after oncological esophagectomy is a severe problem associated with high mortality and morbidity. Unfortunately, treatment options with promising results are scarce especially when conventional operative and endoscopic methods have failed. Due to limitation of oral intake and need for artificial nutrition quality of life is reduced. Microvascular myocutaneous and cutaneous free flap (MFF) reconstruction could be a promising alternative. Methods This retrospective cohort study presents seven patients treated between March 2017 and November 2020 at our surgical department, with terminal esophagostomy after complicated oncological esophagus resection without further feasible treatment options. All Patients received anastomotic MFF reconstruction. We have examined postoperative outcomes, complications according to Clavien-Dindo-Classification and patient contentment with a questionnaire. Additionally, we described important procedure related facts. Results The included seven male patients had median age of 65.15 years (range: 48–75). MFF function was adequate in six out of seven patients, graft rejection appeared in one patient. Five patients initially had good results, surgical revision was performed in one patient to ensure graft function. Postoperative complications appeared in 6/7 patients (Table 1). Mean duration of inpatient care was 63 days (Range: 24–156). At time of evaluation, one patient has died cancer related. No more additional nutrition was needed in 3/6 patients with adequate graft function. The majority of patients reported an improved quality of life compared to preoperatively. Conclusion MFF free flap can be a safe and feasible treatment option for patients with terminal esophagostomy after complicated oncological esophagus resection without further treatment options or in patients with complicated postoperative course with complex combined defects. The renewed ability of oral food intake results in a significant improvement of quality of life for the patients. No procedure related mortality was observed. Number of patients with regained ability of oral intake is encouraging.

Continuous Deep Sedation until Death in Neonates and Infants in Flanders: A Post-Mortem Survey

<b><i>Background:</i></b> The use of analgesics and sedatives to alleviate pain and discomfort is common in end-of-life care in neonates and infants. However, to what extent those drugs are used in that context with the specific aim of bringing the infant in a state of continuous deep sedation (CDS) is currently unknown. <b><i>Methods:</i></b> We performed a nationwide mortality follow-back survey based on all deaths under the age of 1 over a period of 16 months in Flanders, Belgium. Data on CDS were linked to sociodemographic information from death certificates. Physicians completed an anonymous questionnaire. Questions measured whether CDS preceded death, and which clinical characteristics were associated with the sedation (e.g., type of drugs used and the duration of sedation). <b><i>Results:</i></b> The response rate was 83% (229/276). In 39% of all deceased neonates and infants, death was preceded by CDS. Physicians used a combination of morphine and benzodiazepines in 53%, or morphine alone in 45% of all sedation cases in order to continuously and deeply sedate the infant. In 89% of cases, death occurred within 1 week after sedation was begun, and in 92% of cases, artificial nutrition and hydration were administered until death. In 49% of cases there was no intention to hasten death, and in 40% of cases, the possibility of hastening was taken into account. <b><i>Conclusions:</i></b> CDS precedes about 2 in 5 neonatal and infant deaths. Guidelines for CDS in this age group are non-existent and it is unclear whether the same recommendations as in the adult population apply and can be considered a good practice.

Brain–Computer and Brain-to-Brain Interfaces for Communication

This chapter explores how a brain–computer interface (BCI) could allow some patients with locked-in syndrome, amyotrophic lateral sclerosis, or in the minimally conscious state to reliably communicate with others. BCI-mediated communication may enable these patients to clearly express their wishes when they cannot communicate because of motor impairment. Depending on their cognitive capacity for reasoning and decision-making, some patients could use a BCI to express their wishes about life-sustaining treatment and meet criteria of informed consent. Patients who could use a BCI to communicate could decide for themselves whether they want to continue or discontinue artificial nutrition and hydration, ventilation, or other life-sustaining interventions and act in their own best interests. The chapter also discusses how brain-to-brain interfaces may enable communication between brains and minds in a social network of collaborative problem-solving in visuomotor and cognitive tasks.

Stress Hyperglycemia and Osteocalcin in COVID-19 Critically Ill Patients on Artificial Nutrition

We aimed to study the possible association of stress hyperglycemia in COVID-19 critically ill patients with prognosis, artificial nutrition, circulating osteocalcin, and other serum markers of inflammation and compare them with non-COVID-19 patients. Fifty-two critical patients at the intensive care unit (ICU), 26 with COVID-19 and 26 non-COVID-19, were included. Glycemic control, delivery of artificial nutrition, serum osteocalcin, total and ICU stays, and mortality were recorded. Patients with COVID-19 had higher ICU stays, were on artificial nutrition for longer (p = 0.004), and needed more frequently insulin infusion therapy (p = 0.022) to control stress hyperglycemia. The need for insulin infusion therapy was associated with higher energy (p = 0.001) and glucose delivered through artificial nutrition (p = 0.040). Those patients with stress hyperglycemia showed higher ICU stays (23 ± 17 vs. 11 ± 13 days, p = 0.007). Serum osteocalcin was a good marker for hyperglycemia, as it inversely correlated with glycemia at admission in the ICU (r = −0.476, p = 0.001) and at days 2 (r = −0.409, p = 0.007) and 3 (r = −0.351, p = 0.049). In conclusion, hyperglycemia in critically ill COVID-19 patients was associated with longer ICU stays. Low circulating osteocalcin was a good marker for stress hyperglycemia.
