Colorectal surgery in Italy during the Covid19 outbreak: a survey from the iCral study group.

BACKGROUND: The COVID19 pandemic had a deep impact on healthcare facilities in Italy, with profound reorganization of surgical activities. The Italian ColoRectal Anastomotic Leakage (iCral) study group collecting 43 Italian surgical centers experienced in colorectal surgery from multiple regions performed a quick survey to make a snapshot of the current situation. METHODS: A 25-items questionnaire was sent to the 43 principal investigators of the iCral study group, with questions regarding qualitative and quantitative aspects of the surgical activity before and after the COVID19 outbreak. RESULTS: Two-thirds of the centers were involved in the treatment of COVID19 cases. Intensive care units (ICU) beds were partially or totally reallocated for the treatment of COVID19 cases in 72% of the hospitals. Elective colorectal surgery for malignancy was stopped or delayed in nearly 30% of the centers, with less than 20% of them still scheduling elective colorectal resections for frail and comorbid patients needing postoperative ICU care. A significant reduction of the number of colorectal resections during the time span from January to March 2020 was recorded, with significant delay in treatment in more than 50% of the centers. DISCUSSION: Our survey confirms that COVID19 outbreak is severely affecting the activity of colorectal surgery centers participating to iCral study group. This could impact the activity of surgical centers for many months after the end of the emergency.

Does lobectomy for lung cancer in patients with chronic obstructive pulmonary disease affect lung function? A multicenter national study.

OBJECTIVE: The purpose of this study was to evaluate the effect of lobectomy on pulmonary function in patients with chronic obstructive pulmonary disease. METHODS: One hundred thirty-seven patients were analyzed; 49 had normal pulmonary function tests, and 88 had chronic obstructive pulmonary disease. Different functional parameter groups were identified: obstructive (forced expiratory volume in 1 second [FEV1], forced expiratory volume in 1 second/forced vital capacity [FEV1/FVC], and chronic obstructive pulmonary disease index), hyperinflation (residual volume and functional residual capacity), and diffusion (transfer factor of the lung for carbon monoxide). Also, the ratio between observed and predicted postoperative FEV(1) was calculated. RESULTS: In patients with preoperative FEV1 greater than 80% of predicted, postoperative FEV1/FVC slightly but not significantly decreased, and postoperative FEV1 significantly decreased. In patients with preoperative FEV1 less than 65%, postoperative FEV1 and FEV1/FVC significantly increased. In patients with preoperative FEV1/FVC greater than 70%, postoperative FEV1 and FEV1/FVC significantly decreased. In patients with preoperative FEV1/FVC less than 70%, postoperative FEV1/FVC increased, and FEV1 remained unchanged. In patients with a chronic obstructive pulmonary disease index greater than 1.5, postoperative FEV1 and FEV1/FVC significantly decreased, whereas in patients with a chronic obstructive pulmonary disease index less than 1.5, postoperative FEV1/FVC significantly increased and FEV1 remained unchanged. In patients with residual volume and functional residual capacity greater than 115% and transfer factor of the lung for carbon monoxide less than 80% of predicted, postoperative FEV1 diminished less (not significant) compared with patients who had residual volume and functional residual capacity less than 115% (P = .0001). Observed postoperative/predicted postoperative FEV1 was higher if FEV1/FVC was less than 55% (1.46), if FEV1 was less than 80% of predicted (1.21), or if the chronic obstructive pulmonary disease index was less than 1.5 (1.17). CONCLUSIONS: Patients with mild to severe chronic obstructive pulmonary disease could have a better late preservation of pulmonary function after lobectomy than healthy patients.
