RESUMO
BACKGROUND: Adhesive small bowel obstruction (ASBO) is a leading cause of hospitalization in emergency surgery. The occurrence of bowel ischemia significantly increases the morbidity and mortality rates associated with this condition. Current clinical, biochemical and radiological parameters have poor predictive value for bowel ischemia. This study is designed to ascertain predictive elements for the progression to bowel ischemia in patients diagnosed with non-strangulated ASBO who are initially managed through conservative therapeutic approaches. METHODS: The study was based on the previously collected medical records of 128 patients admitted to the Department of Acute Care Surgery of Padua General Hospital, from August 2020 to April 2023, with a diagnosis of non-strangulated adhesive small bowel obstruction, who were then operated for failure of conservative treatment. The presence or absence of bowel ischemia was used to distinguish the two populations. Clinical, biochemical and radiological data were used to verify whether there is a correlation with the detection of bowel ischemia. RESULTS: We found that a Neutrophil-Lymphocyte ratio (NLR) > 6.8 (OR 2.9; 95% CI 1.41-6.21), the presence of mesenteric haziness (OR 2.56; 95% CI 1.11-5.88), decreased wall enhancement (OR 4.3; 95% CI 3.34-10.9) and free abdominal fluid (OR 2.64; 95% CI 1.08-6.16) were significantly associated with bowel ischemia at univariate analysis. At the multivariate logistic regression analysis, only NLR > 6.8 (OR 5.9; 95% CI 2.2-18.6) remained independent predictive factor for small bowel ischemia in non-strangulated adhesive small bowel obstruction, with 78% sensitivity and 65% specificity. CONCLUSIONS: NLR is a straightforward and reproducible parameter to predict bowel ischemia in cases of non-strangulated adhesive small bowel obstruction. Employing NLR during reevaluation of patients with this condition, who were initially treated conservatively, can help the acute care surgeons in the early prediction of bowel ischemia onset.

Background/Objectives: Despite the increased incidence of esophageal cancer (EC) in elderly people, there are no clear guidelines for its treatment in these patients. The aim of this study was to compare the outcomes of patients ≥ 75 years with resectable EC, receiving either upfront esophagectomy or neoadjuvant treatment. Methods: We retrospectively identified 127 patients with resectable EC ≥ 75 years who underwent esophagectomy between January 2000 and December 2022 at our Clinic in the University Hospital of Padova. The included patients were stratified into two groups: patients undergoing upfront esophagectomy (SURG group) and patients receiving neoadjuvant treatment (NAT group). Results: There were no statistically significant differences in OS (p = 0.7708), DFS (p = 0.7827) and cancer-related survival (p = 0.0827) between the SURG and the NAT group, except for the OS of EAC with stage III-IV, where the NAT group experienced a significant benefit in OS (p = 0.0263). When comparing the two groups, patients receiving neoadjuvant treatment experienced a significantly higher rate of postoperative complications (p = 0.0266). At univariate analysis, neoadjuvant therapy was the only variable strongly associated with postoperative morbidity (p = 0.026). Conclusions: Considering the unique characteristics of elderly patients, the choice of a multimodal approach should be tailored to each case in a multidisciplinary setting and balanced with a potential higher risk of postoperative complications, as well as potential toxicity related to chemoradiation and reduced life expectancy.
RESUMO
Gastroesophageal adenocarcinoma is a challenging disease due to its poor prognosis and the presence of few therapeutic options. For these reasons, it is mandatory to identify the subgroup of patients who are at high risk for relapse after curative-intention surgery. In the last years, liquid biopsy has aroused great interest in cancer treatment for its feasibility and the possibility to capture tumor heterogeneity in a real-time way. In postoperative setting, the interest is directed to the identification of Minimal Residual Disease (MRD), defined as isolated or small cluster of cancer cells that residues after curative-intention surgery, and are undetectable by conventional radiological and clinical exams. This review wants to summarize current evidence on the use of liquid biopsy in gastroesophageal cancer, focusing on the detection of ctDNA in the postoperative setting and its potential role as a guide for treatment decision.

Background: Surgical oncological emergencies represent a frequent challenge in acute settings, with postoperative courses characterized by high morbidity and mortality. An accurate selection of patients who could benefit from surgery is essential to avoid unnecessary invasive treatment. In this study, we tried to determine if advanced age (>80 years) represents a risk factor for negative short-term outcome in patients undergoing emergency surgery for acute abdominal oncological illness. Methods: We retrospectively analyzed the records of patients who underwent emergency oncological surgery at the Department of Acute Care Surgery of Padua General Hospital from January 2018 to December 2022. One hundred two cancer patients were included in the study. Among them, 42 were aged ≥80 years (41%). Multiple preoperative and postoperative parameters were recorded, and the follow-up period was at least 90 days. Multivariate logistic regression analyses were used to identify factors associated with short-term postoperative outcomes. Results: In the octogenarian group, 30-day mortality was 11% vs. 9.5% in the younger group [p = not significant (ns)] and 90-day mortality was 17.6% in the octogenarian group vs. 20.5% in the younger group (p = ns). Postoperative morbidity and hospital length of stay were not significantly different in the two groups. Low albumin levels [odds ratio (OR) 30.6, 9.51-87.07] and elevated lactate dehydrogenase (LDH) levels (OR 26.4, 9.18-75.83) were predictive for short-term mortality in surgical oncological emergencies. Conclusion: Advanced age is not a risk factor for negative outcomes in surgical oncological emergencies. Therefore, surgical options should be considered in octogenarians with oncological emergencies and acceptable clinical conditions. Serum albumin levels and LDH can help predict the postoperative outcome after surgery for oncological emergencies.
