RESUMO
BACKGROUND: The reported high surgical morbidity and mortality in patients with SARS-CoV-2 prompted preoperative screening and modification of surgical protocols. Although vaccination and treatment of COVID-19 have resulted in lower hospitalization rates and infection severity, publications on postoperative results have not been updated. The aim of the study was to analyze the outcomes of patients undergoing surgery in two periods with high incidence of SARS-CoV-2 infection, before and after vaccination. MATERIALS AND METHODS: This is a prospective cohort study of patients undergoing surgery in two periods: March-June 2020 (Group2020) and December 2021-February 2022 (Group2022) (after massive vaccination). RESULTS: In total, 618 patients who underwent surgery were included in the analysis (Group2020: 343 vs. Group2022: 275). Significantly more oncological procedures were performed in Group2020, and there were no differences in postoperative complications. Nosocomial SARS-CoV-2 infection occurred in 4 patients in Group2020 and 1 patient in Group2022. In Group 2022, 70 patients (25.4%) had COVID-19 prior to surgery, and 68 (97.1%) were vaccinated. Comparative analysis between patients with past COVID-19 and those without showed no difference in postoperative morbidity and mortality. According to the time elapsed between SARS-CoV-2 infection and surgery (≤ 7 or > 7 weeks), comparative analysis showed no significant differences. CONCLUSION: The establishment of preoperative screening protocols for SARS-CoV-2 infection results in a low incidence of nosocomial infection and optimal postoperative outcomes. Preoperative SARS-CoV-2 infection in vaccinated patients was not associated with increased postoperative complications, even in shorter periods after infection. In surgical patients, individualized preoperative evaluation after SARS-CoV-2 infection may be more important than strict time limitation.

Introduction: The SARS-CoV-2 pandemic has affected training opportunities for healthcare professionals partly because face to face courses were cancelled. This study analyzes the results of participation and satisfaction of the AEC Virtual Classroom sessions during the first year. Methods: The AEC Virtual Classroom includes a combined format of weekly Webinar broadcast live that can be viewed on a delayed basis in a virtual platform. In this study, the results in its first year are evaluated considering the number of live participants, the delayed views and the global reach; as well as the results of the satisfaction survey in each of the sessions (0-10). Results: From 16/04/2020 to 15/04/2021, 50 sessions of the Virtual Classroom AEC were held. The average scope of the sessions was 509 ± 288 views with a range between 196 and 149. At the times of highest incidence of cases during the pandemic, a decrease in live participants was observed 275 ± 135 vs. 391 ± 233 (p = 0.032). The mean score on the format was 8.46 ± 0.31/10. The best-scored sessions were those of the subject related to coloproctology with a statistically significant difference in the mean score 8.79 ± 0.42 vs. 8.39 ± 0.27 (p = 0.035). 90% of users considered the sessions useful. 97.2% of respondents believe that the sessions should be maintained after the pandemic. Conclusions: The AEC Virtual Classroom has a very good results in the first year, proving to be a useful surgical teaching tool that will foreseeably survive once the pandemic is over.
RESUMO
INTRODUCTION: The COVID-19 pandemic has had a significant impact on Spanish hospitals, which have had to allocate all available resources to treat these patients, reducing the ability to attend other common pathologies. The aim of this study is to analyze how the treatment of acute appendicitis has been affected. METHODS: A national descriptive study was carried out by a online voluntary distribution of a specific questionnaire with Google Drive™ distributed by email by the Spanish Association of Surgeons (AEC) to all affiliated surgeons actually working in Spain (5203) opened from April 14th to April 24th. RESULTS: We received 337 responses from 170 centers. During the first month of the pandemic the incidence of acute appendicitis has decreased. Although conservative management has increased, surgical option has been the most used in both simple and complicated appendicitis. Despite the fact that the laparoscopic approach continues to be the most widely used in our services, the open approach has increased during this pandemic period. CONCLUSION: Highlight the contribution of this study in terms of knowledge of the status of the treatment of acute appendicitis during this first month of the pandemic, being able to serve for a better possible organization in future waves of the pandemic and a reorganization of current protocols and management of acute appendicitis in a pandemic situation.
RESUMO
The standard of care for patients with operable gastric adenocarcinoma is perioperative chemotherapy and surgical resection. The deficient mismatch repair (dMMR)/microsatellite instability (MSI-H) phenotype is a major predictive biomarker for immune checkpoint inhibitors (ICIs) efficacy in advanced disease. Several phase II and III trials suggest a promising future role of immunotherapy with or without chemotherapy in the neoadjuvant/adjuvant setting, especially in MSI-H localized gastric adenocarcinomas. We present a 38-year-old man diagnosed in March 2022 with poorly differentiated gastric adenocarcinoma clinical stage III (cT4 N0 M0) with deficiency of MLH1 and PMS2, combined positive score (CPS) of 100 and negative HER2 immunohistochemistry, had poor tumor response to preoperative 5-FU, leucovorin, oxaliplatin, and docetaxel (FLOT). It was considered unresectable because of the involvement of the colon, mesocolon, duodenum, pancreas, and retroperitoneum. Then, first-line systemic treatment with 5-FU, leucovorin, and oxaliplatin (FOLFOX)-nivolumab was initiated in August 2022, with a significant radiologic tumor reduction after six cycles, allowing a curative surgery in March 2023 with complete pathologic tumor response, followed by capecitabine and nivolumab for one year, maintaining radiological remission in the last follow-up in April 2024. With this case report, we conclude that it is likely that chemoimmunotherapy or immunotherapy alone may be alternative neoadjuvant treatment choices for MSI-H locally advanced gastric cancer patients.

The SARS-CoV-2 (COVID-19) pandemic requires an analysis in the field of oncological surgery, both on the risk of infection, with very relevant clinical consequences, and on the need to generate plans to minimize the impact on possible restrictions on health resources. The AEC is making a proposal for the management of patients with hepatopancreatobiliary (HPB) malignancies in the different pandemic scenarios in order to offer the maximum benefit to patients, minimising the risks of COVID-19 infection, and optimising the healthcare resources available at any time. This requires the coordination of the different treatment options between the departments involved in the management of these patients: medical oncology, radiotherapy oncology, surgery, anaesthesia, radiology, endoscopy department and intensive care. The goal is offer effective treatments, adapted to the available resources, without compromising patients and healthcare professionals safety.

The SARS-CoV-2 pandemic has a great impact worldwide, being Spain one of the most affected countries. The delay in bariatric surgery can have fatal consequences since up to 50% of the patients who are on the waiting list develop a new comorbidity during the time they remain on it and 1.5% of patients die while waiting for the intervention. That is why bariatric surgery should not be delayed, if the occupation of the hospital by COVID-19+ patients decreases significantly, and sufficient resources and safety are available to restart surgery in patients with benign pathology. This document contains the main recommendations for the bariatric surgery programs in our country from the point of view of safety, bariatric patient preparation and follow up during the SARS-CoV-2 pandemia.

BACKGROUND: during the COVID-19 pandemic, the number of Acute Care Surgery procedures performed in Spanish hospitals decreased significantly. The aim of this study was to compare Acute Care Surgery activity during the COVID-19 pandemic and during a control period. MATERIAL AND METHODS: a multicenter retrospective cohort study was performed including patients who underwent Acute Care Surgery in three tertiary care hospitals in Spain during a control (11th March 2019 to 21st April 2019) and a pandemic (16th March 2020 to 26th April 2020) period. Type of surgical procedures, patients' features and postoperative complications were compared. RESULTS: two hundred and eighty-five and 117 patients were included in each group. Mean number of patients who underwent Acute Care Surgery during the control and pandemic periods was 2.3 and 0.9 patients per day and hospital (p < 0.001), representing a 58.9% decrease in Acute Care Surgery activity. Time from symptoms onset to patient arrival at the Emergency Department was longer during the pandemic (44.6 vs. 71.0 h, p < 0.001). Surgeries due to acute cholecystitis and complications from previous elective procedures decreased (26.7% vs. 9.4%) during the pandemic, while bowel obstructions and abdominal wall hernia surgeries increased (12.3% vs. 22.2%) (p = 0.001). Morbidity was higher during pandemic period (34.7% vs. 47.1%, p = 0.022), although this difference was not statistically significant in the multivariate analysis. Reoperation rate (17.9% vs. 12.8%, p = 0.212) and mortality (6.7% vs. 4.3%, p = 0.358) were similar in both groups. CONCLUSION: during the COVID-19 pandemic, a significant reduction in the performance of Acute Care Surgery procedures was observed. Moreso, a longer time from symptoms onset to patient arrival at the Emergency Department was noted. Higher morbidity was observed in patients undergoing Acute Care Surgery during the pandemic period, although there was not any difference in mortality or reoperation rate.

Due to the current pandemic of respiratory disease known as coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus, many patients with confirmed or suspected COVID-19 infection will require elective surgery, surgery that cannot be postponed, or emergency surgical treatment. In these situations, special measures need to be adopted in order to minimize the possibility of transmission between patients, exposure of healthcare personnel and the development of postoperative complications. This document explains the main principles to consider when managing confirmed or suspected COVID-19 patients during evaluation as well as when surgical treatment is required.

BACKGROUND/AIMS: The aim of the present work is to clarify the role of metalloproteinase-9 and its inhibitor in the evolution of gastric cancer after surgical resection. METHODOLOGY: We have studied 44 gastric cancer patients submitted to surgery. There were 13 proximal tumors, 16 located in the middle third and 15 in the distal one. Overall survival was 26% at 6 years. Metalloproteinase-9 and tissue inhibitor of metalloproteinase concentrations were investigated by means of ELISA in frozen samples of tumoral and normal gastric mucosa. RESULTS: Mean concentration of metalloproteinase-9 in tumoral tissue was 42 ng/mg of total protein, and this value was 6.9 times greater than the mean concentration in non-tumoral tissue. Cancer tissue also expressed higher levels of TIMP-1, 7.25 versus 4.39 ng/mg of protein. Higher levels of metalloproteinase expression in tumoral tissue, greater [metalloproteinase in tumor]/[metalloproteinase in non-tumor] ratio and greater [metalloproteinase]/[inhibitor] ratio in tumor cells, were all of them statistically related to a worse prognosis when T1 and T2 tumors were considered. CONCLUSIONS: The expression of metalloproteinase-9 or its inhibitor is related to a more aggressive phenotype of gastric cancer.

BACKGROUND: Uncontrolled non-heart-beating donor (UNHBD) transplantation offers a major opportunity to ameliorate the effects of the donor shortage. However, little is known about the true status of the organs obtained from these donors. UNHBD transplantation is performed under unfavorable conditions and involves exposure to several harmful stimuli that have been identified as triggers for immediate inflammatory response, oxidative stress, and apoptotic phenomena. This adverse scenario could explain the higher rates of graft dysfunction due to primary nonfunction traditionally observed in NHBD. Our aim was to assess the expression of proinflammatory, oxidative, and apoptotic markers in liver, lung, and pancreas tissue samples obtained from UNHBD and to compare these expression levels with those observed in brain-dead donors (BDD). METHODS: Samples from human type 2 NHBD and BDD were obtained at the end of cold storage. Interleukin (IL)-1ß, tumor necrosis factor-α, IL-6, IL-10, endothelial nitric oxide synthase, inducible nitric oxide synthase, type 1 heme oxygenase, type 2 heme oxygenase, Bax, and Bcl-2 protein and mRNA expression, as well as catalase, glutathione peroxidase, and glutathione reductase tissue activity, were determined. RESULTS: UNHBD showed similar or lower expression of proinflammatory mediators and apoptosis markers in all three organs without modifications to the anti-inflammatory cytokines. Although the major oxidative stress marker levels were also comparable in both types of donors, the type 1 heme oxygenase mRNA expression and antioxidant enzyme activity were slightly diminished in UNHBD. CONCLUSIONS: The initial tissue damage generated during the UNHB donation process is at least comparable with that observed in BDD. However, although the expression of the immediate immune response and apoptosis markers is similar, a mild impairment of the local antioxidant activity was observed.

Efficacy of ertapenem in biliary tract infections in daily practice was retrospectively analyzed. Records of patients admitted to five Spanish hospitals (January 2007/February 2011) with biliary infections (cholecystitis/cholangitis) treated with ertapenem for ≥72 hours were reviewed. A total of 187 patients (mean 63.8±19.3 years, 52.9% males) were identified. Up to 96 (51.3%) were operated, with cholecystectomy (97.9%) and primary laparoscopy approach (75%) as most frequent intervention. Non-operated patients presented higher age (71.0±17.5 vs 56.9±18.5 years; P<0.001), heart insufficiency (11.0 vs 3.1%; P = 0.044) and the Mortality in Emergency Department Sepsis score (2.99±2.26 vs 1.94±2.34; P<0.001); and longer length of stay (10.3±6.6 vs 9.1±7.0; P = 0.005). Mean duration of treatment was 6.89±3.38 days. Overall favourable response was 87.7% (95% CI = 83.0-92.4) at the end of treatment. In the multivariate analysis (P<0.001, R² Cox = 0.10), non-favourable response was associated with Charlson index≥5 (OR = 18.71; 95% CI: 1.26-278.55; P = 0.034), pericholecystic abscess (OR = 5.30; 95% CI: 1.26-22.37; P = 0.023) and >3 days from symptoms start to admission (OR = 3.02; 95% CI: 1.13-8.04; P = 0.027).

Epithelioid hemangioendothelioma (EH) is a rare tumor of vascular origin, which occurs at sites such as soft tissues, liver, or lung, and has a highly unpredictable malignant potential. It is an intermediate entity between well-differentiated hemangioma and angiosarcoma. We present two cases of this rare disease in which the tumor was detected fortuitously and the definitive diagnosis was based on histological evidence. Both our cases are highly illustrative of the two ways in which hepatic EH can present (nodular or diffuse) and of its diagnostic and therapeutic management. Neoplastic cells expressed the factor VIII-related antigen, CD31 or CD34. Treatment was surgical resection in one patient and liver transplant in the other. Although EH of the liver has a better prognosis than other hepatic neoplasms, conservative treatment is not recommended. Our cases highlight the importance of a histological diagnosis to avoid it being mistaken for another entity.
