RESUMO
Textbook outcome is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. Retrospective study of all patients undergoing scheduled for adrenal tumors surgery at an endocrine surgery unit from January 2010-December 2022. The definition of Textbook Outcome were: R0 resection, no Clavien-Dindo ≥ IIIa complications, no prolonged stay (< P75), no readmissions, and no mortality in the first 30 days. The main objective was to analyze the rate of Textbook Outcome obtained. One hundred and five patients were included in the study. Textbook Outcome was achieved in 71.4%. Surgical approach (p < 0.001), Charlson scale (p = 0.031), American Society of Anesthesiologists Classification (p = 0.047) and surgical time (p < 0.001) were all significantly associated with the achievement of Textbook Outcome. The laparoscopic approach was associated as an independent factor with obtaining Textbook Outcome (OR:5.394; p = 0.016), as was surgical time (OR:0.986; p = 0.004). Textbook Outcome is a novel, useful, easy-to-interpret tool for measuring results in adrenal surgery. The laparoscopic approach is associated with a higher rate of "ideal" surgical results. The study was registered in the public accessible database clinicaltrials.gov with the ClinicalTrials.gov ID: NCT05888753.

BACKGROUND: Precise preoperative localization of liver tumors facilitates successful surgical procedures, Intraoperative ultrasonography is a sensitive imaging modality. However, the presence of small non-palpable isoechoic intraparenchymal lesions may be challenging intraoperatively. METHODOLOGY AND MATERIAL DESCRIPTION: Onyx® is a non-adhesive liquid agent comprised of ethylene-vinyl alcohol usually used dissolved in dimethyl-sulfoxide and suspended micronized tantalum powder to provide contrast for visualization under fluoroscopy and ultrasonography and a macroscopic black shape. This embolization material has been increasingly used for the embolization of intracranial arteriovenous malformations. We present the novel application of Onyx® on liver surgery. CURRENT STATUS: We present the case of a female, 55 years-old, whose medical history revealed an elective sigmoidectomy (pT3N1a). After 17 months of follow up, by PET-CT scan, the patient was diagnosed of a small intraparenchymal hypo-attenuated 13 mm tumor located at segment V consistent with metachronous colorectal liver metastasis. Open metastasectomy was performed, ultrasonography-guided Onyx® infusion was delivered the day after, intraoperative ultrasonography showed a palpable hyperechoic material with a posterior acoustic shadowing artifact around the lesion. Onyx® is a promising new tool, without any previous application on liver surgery, feasible with advantages in small not palpable intraparenchymal liver lesions.

BACKGROUND: Textbook outcome (TO) is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. The aim of the present study is to record the rate of TO in patients undergoing elective surgery for colon cancer (CC). MATERIAL AND METHODS: Retrospective study of all patients undergoing scheduled CC surgery at a Spanish university hospital from September 2012 to August 2016. Patients with rectal cancer were excluded. The variables included in the definition of TO were: R0 resection, number of isolated nodes ≥ 12, no Clavien-Dindo ≥ IIIa complications, no prolonged stay, no readmissions, and no mortality in the first 30 days. The main objective of this study is to analyse the achievement of TO in these patients and to assess the relationship between TO and overall and disease-free survival. RESULTS: Five hundred and sixty-four patients were included in the study. TO was achieved in 49.8%. The sample had a mean age of 69 ± 11 years, and 60% were male. Female sex (OR 1.61; 95% CI 2.30-1.13), T3 and T4 classification (OR 2.50, 95% CI 4.59-1.36, and OR 2.55, 95% CI 5.21-1.24 respectively) and laparoscopic approach (OR 1.53, 95% CI 2.33-1.00) were independent factors that were significantly associated with achieving a TO. Patients who achieved TO had higher overall survival (p = 0.008) than those who did not. However, with regard to disease-free survival, no statistically significant differences were found (p = 0.303). CONCLUSION: TO is a useful, easy-to-interpret management tool for measuring oncological results and for predicting patient survival.

Laparoscopic cholecystectomy is the gold standard for the treatment of acute cholecystitis (AC). Percutaneous cholecystostomy (PC) for management of AC is increasing; safe and less invasive than laparoscopic cholecystectomy and is very useful in selected patients with severe comorbidities, not suitable for surgery/general anesthesia. We conducted a retrospective observational study between 2016 and 2021 of patients treated with PC for AC, based on the application of the Tokyo guidelines 13/18. The aim was to analyse the clinical results and management of PC in patients undergoing elective or emergency cholecystectomy. Subsequently, a retrospective analytical study was designed to compare various cohorts: elective or emergency surgery and management with PC alone; patients with/without a high surgical risk; and elective vs emergency surgery. Hundred and ninety five patients with AC were treated with PC. Mean age was 74 years, 59.5% were ASA class III/IV, and the mean Charlson comorbidity index was 5.5. Adherence to Tokyo guidelines regarding indication of PC was 50.8%. The rate of complications associated to PC was 12.3% and the 90-day mortality rate was 14.4%. Mean length of time using PC was 10.7 days. Emergency surgery was performed in 4.6%. The overall success rate using PC was 66.7%, and the 1-year readmission rate due to biliary complications after PC was 28.2%. The rate of scheduled cholecystectomy after PC was 22.6%. Conversion to laparotomy and open approach was more frequent in patients who underwent emergency surgery (p = 0.009). No differences were found in 90-day mortality or in the complication rate. PC achieves improvements in the inflammation and infection associated with AC. In our series, it proved to be an effective and safe treatment during the acute episode of AC. Mortality in patients treated with PC is high due to their older age, greater morbidity, and higher Charlson comorbidity index scores. After PC, emergency surgery is uncommon but readmission due to biliary events is high. Cholecystectomy after PC is the definitive treatment and the laparoscopic approach is feasible. Clinical trial registery: The study was registered in the public accessible database clinicaltrials.gov with the ClinicalTrials.gov ID: NCT05153031. Public release date: 12/09/2021.

The physiological role of the gastrointestinal microbiota has become an important subject of nutrition research in pigs in the past years, and the importance of intestinal microbial activity in the etiology of disease is doubtless. This review summarizes the recent knowledge related to the microbial ecology of protein fermentation and the appearance of protein-derived metabolites along the pig intestine. The amount of fermentable protein depends on factors such as dietary protein concentration, protein digestibility due to secondary or tertiary structure, the interaction with dietary compounds or anti-nutritional factors, and the secretion of endogenous proteins into the gut lumen. High protein diets increase the luminal concentrations and epithelial exposure to putatively toxic metabolites and increase the risk for post-weaning diarrhea, but the mechanisms are not yet clarified. Although the use of fermentable carbohydrates to reduce harmful protein-derived metabolites in pigs is well-established, recent studies suggest that the inclusion of fermentable carbohydrates into diets with low protein digestibility or high dietary protein level may not ameliorate all negative effects with regard to epithelial response. Based on the current knowledge, the use of diets with low levels of high-quality protein may help to reduce the risk for intestinal disease in young pigs.

The exocrine pancreas plays an important role in zinc homeostasis. Feeding very high (2000-3000mgzinc/kg diet) levels of zinc oxide to piglets for short periods is a common practice in the swine industry to improve performance and prevent diseases. The impact on pancreatic function and possible side effects during long-term feeding of high dietary zinc levels are still poorly understood. A total of 54 weaned piglets were either fed with low (57mg/kg, LZn), normal (164mg/kg, NZn) or high (2425mg/kg, HZn) zinc concentration in the diets. After 4 weeks of feeding, ten piglets per treatment were euthanized and pancreas samples were taken. Tissue zinc concentration and metallothionein abundance was greater with HZn compared with NZn and LZn (P<0.05). Similarly, activity of α-amylase, lipase, trypsin and chymotrypsin was higher with HZn as compared with NZn and LZn diets (P<0.05), whereas elastase activity was unchanged. Total trolox equivalent antioxidative capacity of pancreas tissue was higher with HZn diets compared with the other treatments (P<0.05). Pancreatic protein profiles of NZn and HZn fed piglets were obtained by 2D-DIGE technique and revealed 15 differentially expressed proteins out of 2100 detected spots (P<0.05). The differentially expressed proteins aldose reductase, eukaryotic elongation factor II and peroxiredoxin III were confirmed by immunoblotting. Identified proteins include zinc finger-containing transcription factors and proteins mainly associated with oxidative stress response and signal transduction in HZn compared with NZn pigs. Histologic examination however showed no morphologic changes. The results suggest that long-term supply of very high dietary zinc increases zinc and metallothionein concentration, and digestive enzyme activity, but also triggers oxidative stress reactions in the pancreas of young pigs. The data provide new insights into pancreatic function under outbalanced zinc homeostasis.
