Intestinal failure ( IF) is a debilitating condition of inadequate nutrition due to an anatomical and/or physiological deficit of the intestine. Surgical management of patients with acute and chronic IF requires expertise to deal with technical challenges and make correct decisions. Dedicated IF units have expertise in patient selection, operative risk assessment and multidisciplinary support such as nutritional input and interventional radiology, which dramatically improve the morbidity and mortality of this complex condition and can beneficially affect the continuing dependence on parenteral nutritional support. Currently there is little guidance to bridge the gap between general surgeons and specialist IF surgeons. Fifteen European experts took part in a consensus process to develop guidance to support surgeons in the management of patients with IF. Based on a systematic literature review, statements were prepared for a modified Delphi process. The evidence for each statement was graded using Oxford Centre for Evidence-Based Medicine Levels of Evidence. The current paper contains the statements reflecting the position and practice of leading European experts in IF encompassing the general definition of IF surgery and organization of an IF unit, strategies to prevent IF, management of acute IF, management of wound, fistula and stoma, rehabilitation, intestinal and abdominal reconstruction, criteria for referral to a specialist unit and intestinal transplantation.

Objectives - 1. To find out whether a stay in local general practitioner hospitals (GP hospitals) prior to an emergency admission to higher level hospitals aggravated or prolonged the course of the disease, or contributed to permanent health loss for some patients. 2. To detect cases where a transitory stay in a GP hospital might have been favourable. Design - A retrospective expert panel study based on records from GP hospitals and general hospitals. The included patients had participated in a previous prospective study of consecutive admissions to GP hospitals during 8 weeks. Setting - Fifteen out of 16 GP hospitals in Finnmark county, Norway. Subjects - Seventy-three patients transferred to higher level hospitals from a total of 395 admitted to GP hospitals. Main outcome measures - Three outcome categories were considered for each patient: 'possible permanent health loss', 'possible significantly prolonged or aggravated disease course', and 'possible favourable effect on the disease course'. Results - There was agreement about the possibility of negative effects in two patients (2.7%), while a possible favourable influence was ascribed to six cases (8.2%). Conclusion - Negative health effects due to transitory stays in GP hospitals are uncommon and moderate, and balanced by benefits, particularly with regard to early access to life saving treatment for critically ill patients.

Patients in intensive care have increased nutritional needs but are often incapable of eating independently. When should intravenous parenteral nutrition be started, and what is the optimal dose? Here we review the recently updated European guidelines on nutritional support in intensive care patients.

Insulin resistance is an independent negative predictor of outcome after elective surgery and increases mortality among surgical patients in intensive care. The incretin hormone glucagon-like peptide-1 (GLP-1) potentiates glucose-induced insulin release from the pancreas but may also increase insulin sensitivity in skeletal muscle and directly suppress hepatic glucose release. Here, we investigated whether a perioperative infusion of GLP-1 could counteract the development of insulin resistance after surgery. Pigs were randomly assigned to three groups; surgery/control, surgery/GLP-1, and sham/GLP-1. Both surgery groups underwent major abdominal surgery. Whole-body glucose disposal (WGD) and endogenous glucose release (EGR) were assessed preoperatively and postoperatively using D-[6,6-2H2]-glucose infusion in combination with hyperinsulinemic euglycemic step-clamping. In the surgery/control group, peripheral insulin sensitivity (i.e., WGD) was reduced by 44% relative to preoperative conditions, whereas the corresponding decline was only 9% for surgery/GLP-1 (P < 0.05). Hepatic insulin sensitivity (i.e., EGR) remained unchanged in the surgery/control group but was enhanced after GLP-1 infusion in both surgery and sham animals (40% and 104%, respectively, both P < 0.05). Intraoperative plasma glucose increased in surgery/control (∼20%) but remained unchanged in both groups receiving GLP-1 (P < 0.05). GLP-1 diminished an increase in postoperative glucagon levels but did not affect skeletal muscle glycogen or insulin signaling proteins after surgery. We show that GLP-1 improves intraoperative glycemic control, diminishes peripheral insulin resistance after surgery, and suppresses EGR. This study supports the use of GLP-1 to prevent development of postoperative insulin resistance., (Copyright © 2019 Endocrine Society.)

Background/objectives: In 2004, a survey conducted in Scandinavia documented insufficient knowledge in nutrition care among doctors and nurses. The survey also revealed a significant discrepancy in nutritional practice, where Norway ranked lowest, thus leading to several actions including elaboration of national guidelines. The aim of this study was to evaluate potential changes in nutritional practice, as well as assessing barriers to nutrition therapy, 10 years after the former study., Subjects/methods: In the first half of 2014, a total of 4000 doctors and nurses received a questionnaire, similar to the one used in 2004. The questions dealt with nutritional practice, routines, knowledge, barriers, and use of clinical dietitians (CDs) in the hospitals., Results: The response rate was 22%. Routines in nutritional practice were significantly improved. The level of knowledge among respondents were increased, but lack of knowledge and lack of assignment of responsibility were still important barriers. The patients' contradiction could be a barrier to the use of enteral nutrition. CDs are used in a small amount of patients, and wards with good nutritional routines have a better cooperation with CDs than wards with insufficient routines., Conclusions: Routines in clinical nutrition have improved from 2004 to 2014. Barriers in the daily practice among health care workers like lack of knowledge and lack of assignment of responsibility are still important, and health care professionals seem to let the patient himself or herself be a barrier to the use of enteral nutrition.

Intestinal failure (IF) is the consequence of a reduction of gut function below the minimum necessary for the absorption of nutrients from the gastrointestinal tract. Types I and II comprise acute intestinal failure (AIF). Although its prevalence is relatively low, type II AIF is serious and requires specialist multidisciplinary care, often for prolonged periods before its resolution. The key aspects are: sepsis control, fluid and electrolyte resuscitation, optimization of nutritional status, wound care, appropriate surgery and active rehabilitation. The ESPEN Acute Intestinal Failure Special Interest Group (AIF SIG) has devised this position paper to provide a state-of-the-art overview of the management of type II AIF and to point out areas for future research., (Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Background & Aims: We hypothesized that the so far poorly understood improvement in postoperative insulin sensitivity, when surgery is preceded by a carbohydrate (CHO) drink, occurs via attenuation of skeletal muscle inflammatory responses to surgery, improved insulin signaling and attenuated expression of muscle pyruvate dehydrogenase kinase (PDK) 4., Methods: Vastus lateralis muscle biopsies, collected before and after major abdominal surgery and during postoperative hyperinsulinaemic-euglycaemic clamping from 16 pigs randomized to either 200 ml of a CHO-supplemented drink 2 h before surgery (CHO, 25 g; n = 8), or preoperative overnight fasting (fasted; n = 8), were analyzed by fast qRT-PCR and IR-Western blotting., Results: During clamping, expression of IKKβ, SOCS3 and the ratio of phosphorylated/total JNK2 proteins were lower in the CHO group than in the fasted group (-1.0 vs. 2.9-fold, P < 0.001; -0.6 vs. 3.2-fold, P < 0.01; and -0.5 vs. 1.1-fold, P < 0.02, respectively). Furthermore, the ratio of Ser(307)-phosphorylated (inhibition)/total IRS1 protein was reduced only in the CHO group (-2.4 fold, P < 0.02), whereas FOXO1 phosphorylation (inactivation), which correlated negatively with PDK4 mRNA (r(2) = 0.275, P < 0.05), was lower in the CHO group than in the fasted group (-1.1-fold, P > 0.05 vs. -2.3-fold, P = 0.05). Post-surgery, PDK4 mRNA increased ∼20-fold (P < 0.01) in both groups, but was reversed to a greater extent by insulin in the CHO group (-40.5 vs. -22.7-fold, P < 0.05), resulting in 5-fold lower PDK4 protein levels, which correlated negatively with insulin-stimulated whole-body glucose disposal rates (r(2) = -0.265, P < 0.05)., Conclusions: Preoperative carbohydrate supplementation was found to ameliorate postoperative insulin sensitivity by reducing muscle inflammatory responses and improved insulin inhibition of FOXO1-mediated PDK4 mRNA and protein expression after surgery., (Copyright © 2014 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Development of acute insulin resistance represents a negative factor after surgery, but the underlying mechanisms are not fully understood. We investigated the postoperative changes in insulin sensitivity, mitochondrial function, enzyme activities, and release of reactive oxygen species (ROS) in skeletal muscle and liver in pigs on the 2nd postoperative day after major abdominal surgery. Peripheral and hepatic insulin sensitivity were assessed by D-[6,6-²H₂]glucose infusion and hyperinsulinemic euglycemic step clamping. Surgical trauma elicited a decline in peripheral insulin sensitivity (∼34%, P<0.01), whereas hepatic insulin sensitivity remained unchanged. Intramyofibrillar (IFM) and subsarcolemma mitochondria (SSM) isolated from skeletal muscle showed a postoperative decline in ADP-stimulated respiration (V(ADP)) for pyruvate (∼61%, P<0.05, and ∼40%, P<0.001, respectively), whereas V(ADP) for glutamate and palmitoyl-L-carnitine (PC) was unchanged. Mitochondrial leak respiration with PC was increased in SSM (1.9-fold, P<0.05) and IFM (2.5-fold, P<0.05), indicating FFA-induced uncoupling. The activity of the pyruvate dehydrogenase complex (PDC) was reduced (∼32%, P<0.01) and positively correlated to the decline in peripheral insulin sensitivity (r=0.748, P<0.05). All other mitochondrial enzyme activities were unchanged. No changes in mitochondrial function in liver were observed. Mitochondrial H₂O₂ and O₂·⁻ emission was measured spectrofluorometrically, and H₂O₂ was increased in SSM, IFM, and liver mitochondria (∼2.3-, ∼2.5-, and ∼2.3-fold, respectively, all P<0.05). We conclude that an impairment in skeletal muscle mitochondrial PDC activity and pyruvate oxidation capacity arises in the postoperative phase along with increased ROS emission, suggesting a link between mitochondrial function and development of acute postoperative insulin resistance., (Copyright © 2015 the American Physiological Society.)

Background & Aims: Intestinal failure (IF) is not included in the list of PubMed Mesh terms, as failure is the term describing a state of non functioning of other organs, and as such is not well recognized. No scientific society has yet devised a formal definition and classification of IF. The European Society for Clinical Nutrition and Metabolism guideline committee endorsed its "home artificial nutrition and chronic IF" and "acute IF" special interest groups to write recommendations on these issues., Methods: After a Medline Search, in December 2013, for "intestinal failure" and "review"[Publication Type], the project was developed using the Delphi round methodology. The final consensus was reached on March 2014, after 5 Delphi rounds and two live meetings., Results: The recommendations comprise the definition of IF, a functional and a pathophysiological classification for both acute and chronic IF and a clinical classification of chronic IF. IF was defined as "the reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that intravenous supplementation is required to maintain health and/or growth"., Conclusions: This formal definition and classification of IF, will facilitate communication and cooperation among professionals in clinical practice, organization and management, and research., (Copyright © 2014 The Authors.

Background & Aims: Preoperative oral carbohydrate (CHO) treatment is known to reduce postoperative insulin resistance, but the necessity of a preoperative evening dose is uncertain. We investigated the effect of single-dose CHO treatment two hours before surgery on postoperative insulin sensitivity., Methods: Thirty two pigs (∼ 30 kg) were randomized to 4 groups (n = 8) followed by D-[6,6-(2)H2] glucose infusion and hyperinsulinemic-euglycemic step clamping. Two groups received a morning drink of 25 g carbohydrate (CHO/surgery and CHO/control). Animals in the other two groups were fasted overnight (fasting/surgery and fasting/control). Counter-regulatory hormones, free fatty acids (FFA) and liver and muscle glycogen content were measured serially., Results: Glucose infusion rates needed to maintain euglycemia were higher after CHO/surgery than fasting/surgery during low (8.54 ± 0.82 vs. 6.15 ± 0.27 mg/kg/min, P < 0.05), medium (17.26 ± 1.08 vs. 14.02 ± 0.56 mg/kg/min, P < 0.02) and high insulin clamping (19.83 ± 0.95 vs. 17.16 ± 0.58 mg/kg/min, P < 0.05). The control groups exhibited identical insulin sensitivity. Compared to their respective controls, insulin-stimulated whole-body glucose disposal was significantly reduced after fasting/surgery (-41%, P < 0.001), but not after CHO/surgery (-16%, P = 0.180). CHO reduced FFA perioperatively (P < 0.05) and during the clamp procedures (P < 0.02), but did not affect hepatic insulin sensitivity, liver and muscle glycogen content or counter-regulatory hormone profiles. A strong negative correlation between peripheral insulin sensitivity and mean cortisol levels was seen in fasted (R = -0.692, P = 0.003), but not in CHO loaded pigs., Conclusions: Single-dose preoperative CHO treatment is sufficient to reduce postoperative insulin resistance, possibly due to the antilipolytic effects and antagonist properties of preoperative hyperinsulinemia on the suppressant actions of cortisol on carbohydrate oxidation., (Copyright © 2014 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

The present study aimed to establish hyperinsulinemic euglycemic step clamping with tracer glucose infusion and labeled glucose infusate (step hot-GINF HEC) for assessment of acute insulin resistance in anesthetized pigs and to arrange for combination with invasive investigative methods. Tracer enrichment was measured during D-[6,6-(2)H(2)]glucose infusion before and after surgical instrumentation (n = 8). Insulin dose-response characteristics were determined by two step hot-GINF HEC procedures, with accordingly labeled glucose infusates performed at a total of six insulin infusion rates ranging from 0.2 to 2.0 mU kg(-1) min(-1) (n = 8). Finally, three-step hot-GINF HEC (0.4, 1.2, and 2.0 mU kg(-1) min(-1)) was performed subsequent to major surgical trauma (n = 8). Tracer enrichment, basal glucose kinetics, and circulating levels of C-peptide, cortisol, glucagon, and catecholamines were not influenced by surgical instrumentation. Mean intraindividual coefficient of variance levels for glucose infusion rates and repeatedly measured insulin, glucose, and tracer enrichment indicated stable clamping conditions. Basal and maximal insulin-stimulated glucose utilization was twice as high as in humans at approximately 5.5 and 21 mg kg(-1) min(-1). Surgical trauma elicited pronounced peripheral and moderate hepatic insulin unresponsiveness (45% lower whole body glucose disposal and 19% less suppressed endogenous glucose release) and apparently diminished metabolic insulin clearance. Step hot-GINF HEC seems suitable for assessment of acute insulin resistance in anesthetized pigs, and combination with invasive investigative methods requiring surgical instrumentation can be accomplished without the premises for utilization of the technique being altered, but attention must be paid to alterations in metabolic insulin clearance.

Background & Aims: Though a great interest and willingness to nutrition therapy, there is an insufficient practice compared to the proposed ESPEN guidelines for nutrition therapy. The aim of this questionnaire was to study doctors and nurses' self-reported knowledge in nutritional practice, with focus on ESPEN's guidelines in nutritional screening, assessment and treatment., Methods: A questionnaire about different aspects of nutritional practice was answered by 4512 doctors and nurses in Denmark, Sweden and Norway., Results: The most common cause for insufficient nutritional practice was lack of nutritional knowledge. Twenty-five percent found it difficult to identify patient in need of nutritional therapy, 39% lacked techniques for identifying malnourished patients, and 53% found it difficult to calculate the patients' energy requirement and 66% lacked national guidelines for clinical nutrition. Twenty-eight percent answered that insufficient nutrition practice could lead to complications and prolonged hospital stay. Those that answered that their nutritional knowledge was good had also a better nutritional practice., Conclusion: The self-reported nutritional knowledge was inadequate among Scandinavian doctors and nurses. Increased nutritional knowledge seems to improve the nutritional practice. A combination of an integrated nutrition curriculum during the education, together with post-graduated education for both physicians and nurses should be established.

Background and Aims: Hospital malnutrition is prevalent, but nutritional practice in hospitals has a low priority. To improve the quality in nutritional routine, ESPEN has developed standards to improve the inadequate and insufficient nutritional treatments seen today. However, there is a discrepancy between the standards and clinical practice. This study was conducted to investigate nutritional practice in different hospital settings in relation to these standards (e.g.: screening of all patients, assessment of at-risk patients) among Scandinavian doctors and nurses., Methods: A questionnaire about nutritional attitudes and routine was mailed to doctors and nurses in Denmark, Sweden and Norway., Results: Altogether, 4512 (1753 doctors, 2759 nurses) answered the questionnaire. Both screening and assessment of at-risk patients differ between the countries. Nutritional screening was more common in Denmark (40%), compared to Sweden (21%) and Norway (16%). Measuring dietary intake in nutritional at-risk patients was more common in Denmark (46%), compared to Sweden (37%) and Norway (22%). However, all countries agreed that nutritional screening (92%, 88%, 88%) and measuring dietary intake (97%, 95%, 97%) were important, Denmark, Sweden and Norway, respectively., Conclusion: There is a large discrepancy between nutritional attitudes and practice. The standards suggested from the ESPEN are not fulfilled.

Background: It may be difficult to decide whether a patient's discomfort is related to known gallbladder stones., Material and Methods: A questionnaire regarding pre- and postoperative complaints and satisfaction with treatment was sent to 211 patients a median 51 months after they had undergone cholecystectomy at Rana district hospital during the May 1993 to March 2001 period., Results: 97% of the patients returned our questionnaire. 80% had experienced sudden bursts of pain; in 91% of them the pain was relieved. 71% reported no complaints after cholecystectomy, 26% still had some discomfort after the operation. Two thirds of these had experienced discomfort for several years. 22% reported new or different symptoms. After surgery our patients reported a significant reduction in symptoms like sudden pain, constant pain, nausea/vomiting and bloating. 94% were very satisfied or satisfied with the outcome; 1% regretted having undergone the procedure., Interpretation: Sudden attacks of pain are likely to be relieved after cholecystectomy. Our patients also experienced a number of different types of discomfort both before and after the cholecystectomy. Similar complaints also are reported by persons without gallstones, hence it is difficult to interpret the relief or worsening of these symptoms in relation to the cholecystectomy.

Background: The aim of this study was to examine the results of incisional hernia repair in our institution., Material and Methods: Repairs performed in from the start of 1998 to the end of 2001 were identified and the case notes reviewed. Some patients were also interviewed by telephone. Preoperative risk factors, type of repair, complications and recurrence were registered., Results: 90 repairs were performed. The patients were followed up for 36 months on average. 58 (64%) patients had preoperative risk factors. 36 (40%) patients suffered complications, mostly seroma and wound infection. 39 (43%) patients experienced recurrence., Discussion: Incisional hernia repair was associated with a high risk of complications and recurrence.

Background: Health authorities and patients are expected to be more active in inquiring about the outcome of surgery for each specific hospital. Prospective registration performed in a district hospital has to go on for years until the results can be evaluated. Specific data for gallbladder surgery performed in Norwegian district hospitals have not been reported before., Material and Methods: All 220 cholecystectomies carried out from May 1993 to March 2001 were registered prospectively., Results: Two surgeons performed 93% of the operations with an average annual operator volume of 28. The operation rate was 8.5 per 10,000 inhabitants. The need for conversion was 9%. The peri and postoperative complication rate for laparoscopic and converted operations was 11%., Interpretation: Our operation rate is somewhat higher than the average in Norway. The number of annual operations in a district hospital is somewhat low, but as almost all procedures are carried out by a limited number of surgeons, operator volume is compatible with data from larger hospitals in Norway. The need for conversion and the rate and seriousness of complications peri and postoperatively does not seem to be higher in this district hospital than in county and university hospitals in Norway.

Background: Agenesis of the gallbladder, first described in 1701, is a rare, congenital malformation with an incidence of 0.01% to 0.04%. The condition can be associated with other and multiple anomalies. The diagnosis can be a random discovery during an abdominal operation or at autopsy, or an astonishing perioperative finding in a patient presenting with symptoms compatible with gallstone disease., Material and Methods: We present a young man with symptoms interpreted as related to gallstones. The preoperative ultrasound was misaprehended, describing a small, shrunken gallbladder filled with stones., Results: At laparoscopy we found no gallbladder, but a small accumulation of connective tissue and a cord-like structure believed to be the cystic duct. Attempts to cannulate this structure failed. Postoperative endoscopic retrograde cholangiography (ERC) showed normal intra- and extrahepatic biliary ducts, but no gallbladder or cystic duct. Five years after the laparoscopy the patient still experiences attacks of pain located to the right hypogastric area., Interpretation: Though agenesis of the gallbladder is a rare condition, surgeons and radiologists should be aware of it. Uncertain ultrasound pictures should be supplied by more advanced CT or MR techniques to avoid unnecessary operations searching for an absent gallbladder.
