This observational prospective study aims to evaluate the postoperative analgesic effect of a regional anesthesia thechnique (TAP block) in patients undergoing scheduled laparoscopic intestinal resection for intestinal cancer. ASA I-III patients operated between May 1 and September 30, 2019 under general anesthesia according to usual clinical practice, will be included. Patients who meet any of the following criteria will be excluded from this study: under 18 years old, language barrier, cognitive impairment or inability to assist in clinical assessment, drug or alcohol abuse, intake of opioids, consumption of analgesics 24 hours before surgery, BMI \<18 or \>35 kg/m2. Subsequently, an analysis will be made evaluating the quality of analgesia and the appearance of postoperative chronic pain and comparing the patients who underwent TAP block with those who did not.
