Introduction: The effectiveness of the Enhanced Recovery After Surgery (ERAS) protocols in gastric cancer surgery remains controversial., Methods: Multicentre prospective cohort study of adult patients undergoing surgery for gastric cancer. Adherence with 22 individual components of ERAS pathways were assessed in all patients, regardless of whether they were treated in a self-designed ERAS centre. Each centre had a three-month recruitment period between October 2019 and September 2020. The primary outcome was moderate-to-severe postoperative complications within 30 days after surgery. Secondary outcomes were overall postoperative complications, adherence to the ERAS pathway, 30 day-mortality and hospital length of stay (LOS)., Results: A total of 743 patients in 72 Spanish hospitals were included, 211 of them (28.4 %) from self-declared ERAS centres. A total of 245 patients (33 %) experienced postoperative complications, graded as moderate-to-severe complications in 172 patients (23.1 %). There were no differences in the incidence of moderate-to-severe complications (22.3% vs. 23.5%; OR, 0.92 (95% CI, 0.59 to 1.41); P = 0.068), or overall postoperative complications between the self-declared ERAS and non-ERAS groups (33.6% vs. 32.7%; OR, 1.05 (95 % CI, 0.70 to 1.56); P = 0.825). The overall rate of adherence to the ERAS pathway was 52% [IQR 45 to 60]. There were no differences in postoperative outcomes between higher (Q1, > 60 %) and lower (Q4, ≤ 45 %) ERAS adherence quartiles., Conclusions: Neither the partial application of perioperative ERAS measures nor treatment in self-designated ERAS centres improved postoperative outcomes in patients undergoing gastric surgery for cancer., Trial Registration: ClinicalTrials.gov Identifier NCT03865810., (Copyright © 2023 AEC.

N-methyl-D-aspartate receptor encephalitis is an autoimmune encephalitis relationated or not with a neoplasm. Although its incidence is unknown, probably remains underdiagnosed. Epidemiological studies place it as the second cause of immune-mediated encephalitis and the first in patients aged less of 30 years. It shows neuropsychiatric symptoms and autonomic instability. After diagnosis, based on the detection of antibodies in serum or cerebrospinal fluid, an occult malignancy must be investigated. While increasing number of cases have been diagnosed and the important role of this receptor in general anesthesia mechanisms, the interaction of the disease with anesthetic agents and perioperative stress is unknown. We describe the case of a patient with encephalitis associated to ovarian teratoma that underwent gynaecological laparoscopy., (Copyright © 2014 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.
