Colorectal medullary carcinoma (CMC) is a rare subset of minimally differentiated carcinomas. CMC tend to be right-sided and present at an advanced stage. Despite this, distant metastases are rare at presentation. The liver and the regional lymph nodes represent the most common sites of metastases. Most of the time, CMCs exhibit mismatch repair deficiency and a strong association with high-level microsatellite instability. There is no conspicuous data regarding treatment strategies and short-term outcomes. CMC is supposed to be related to better prognosis compared to poorly-differentiated and undifferentiated colonic adenocarcinomas, but reports are controversial.This lesion, with heterogeneous presentations and unclear prognostic significance, may be unfamiliar to histopathologists and can lead to diagnostic uncertainty and overtreatments.Our aim is to renew the attention to this rare histological subtype through the report of two cases.

Background: During the outbreak of coronavirus disease 2019 (COVID-19), allocating intensive care beds to patients needing acute care surgery became a very difficult task. Moreover, since general anesthesia is an aerosol-generating procedure, its use became controversial. This strongly restricted therapeutic strategies. Here, we report a series of undeferrable surgical cases treated with awake surgery under neuraxial anesthesia. Contextual benefits of this approach are deepened. Methods: During the first pandemic surge, thirteen patients (5 men and 8 women) with a mean age of 80 years, needing undelayable surgery due to abdominal emergencies, underwent awake open surgery at our Hospital. Prior to surgery, all patients underwent nasopharyngeal swab tests for COVID-19 diagnosis. In all cases, regional anesthesia (spinal, epidural, or combined spinal-epidural anesthesia) was performed. Intraoperative and postoperative pain intensities have been monitored and regularly assessed. A distinct pathway has been set up to keep patients of uncertain COVID-19 diagnosis separated from all other patients. Postoperative course has been examined. Results: The mean operative time was 87 minutes (minimum 60 minutes; maximum 165 minutes). In one case, conversion to general anesthesia was necessary. Postoperative pain was always well controlled. None of them required postoperative intensive care support. No perioperative major complications (Clavien-Dindo ≥3) occurred. Early readmission after surgery never occurred. All nasopharyngeal swabs resulted negative. Conclusions: In our experience, awake laparotomy under regional anesthesia resulted feasible, safe, painless, and, in specific cases, was the only viable option. This approach allowed prevention of the need of postoperative intensive monitoring during the COVID-19 era. In such a peculiar time, we believe it could become part of an ICU-preserving strategy and could limit viral transmission inside theatres.

BACKGROUND: During Coronavirus disease (COVID-19) pandemic entire countries rapidly ran out of intensive care beds, occupied by critically ill infected patients. Elective surgery was initially halted and acute non-deferrable surgical care drastically limited. The presence of COVID-19 patients into intensive care units (ICU) is currently decreasing but their congestion have restricted our therapeutic strategies during the last months. METHODS: In the COVID-19 era eighteen patients (8 men, 10 women) with a mean age of 80 years, needing undelayable abdominal surgery underwent awake open surgery at our Department. Prior to surgery, all patients underwent COVID-19 investigation. In all cases locoregional anesthesia (LA) was performed. Intraoperative and postoperative pain has been monitored and regularly assessed. A distinct pathway has been set up to keep patients of uncertain COVID-19 diagnosis separated from all other patients. RESULTS: Mean operative time was 104 minutes. In only one case conversion to general anesthesia was necessary. Postoperative pain was always well controlled. None of them required postoperative intensive care support. Only one perioperative complication occurred. Early readmissions after surgery were never observed. CONCLUSIONS: On the basis of our experience awake laparotomy under LA resulted feasible, safe, painless and, in specific cases, the only viable option. For patients presenting fragile cardiovascular and respiratory, reserves and in whom general anesthesia (GA) would presumably increase morbidity and mortality we encourage LA as an alternative to GA. In the COVID-19 era, it has become part of our ICU-preserving strategy allowing us to carry out undeferrable surgeries.
