[The clinical importance of the critical view of safety in laparoscopic cholecystectomy]. / Die klinische Bedeutung des "critical view of safety" in der laparoskopischen Gallenblasenchirurgie.

BACKGROUND: Injury of the bile duct during cholecystectomy (CHE) is a severe complication. The critical view of safety (CVS) can help to reduce the frequency of this complication during laparoscopic CHE. So far, no scoring of CVS images with a grading system is available. METHOD: The CVS images of 534 patients with laparoscopic CHE could be structurally analyzed and assessed with marks from 1 (very good) to 5 (insufficient). The CVS mark was correlated with the perioperative course. Additionally, the perioperative course of patients after laparoscopic CHE with and without a CVS image was investigated. RESULTS: In 534 patients 1 or more CVS images could be analyzed. The average CVS mark was 1.9, whereby 280 patients (52.4%) had a 1, 126 patients (23.6%) a 2, 114 (21.3%) a 3 and 14 patients (2.6%) a 4 or 5. Younger patients with elective laparoscopic CHE had CVS images significantly more frequently (p ≤ 0.04). The statistical examination with Pearson's χ2-test and the F­test (ANOVA) showed a significant correlation between improving CVS marks and reduction of surgery time (p < 0.01) and the hospitalization time (p < 0.01). For senior physicians the quota of CVS images ranged from 71% to 92% and the average marks from 1.5 to 2.2. The marks for the CVS images were significantly better for female than male patients (1.8 vs. 2.1, p < 0.01). DISCUSSION: There was a relatively broad distribution of marks for CVS images. Injuries of the bile duct can be avoided with a high degree of certainty with marks 1­2 for the CVS image. The CVS is not always adequately visualized in laparoscopic CHE.

[The COVID-19 pandemic had significant impact on duration of surgery and hospitalization time for patients after cholecystectomy]. / Die Auswirkungen der COVID-19 Pandemie führten zu signifikanten Veränderungen der Operations- und Liegezeiten bei Patienten nach Cholezystektomie.

BACKGROUND: The COVID-19 pandemic made substantial changes in medical care necessary. The aims of this study were to find out what influence the pandemic had on the perioperative course in patients with cholecystectomy (CHE) and to highlight possible residual consequences. METHOD: From 1 July 2018 to 31 December 2021 a total of 735 patients with CHE were analyzed. Up to 21 March 2020 patients were assigned to the regular patient group (Reg, n = 430), patients after this date (first lockdown 22 March 2020) to the Cov19 patient group (Cov19, n = 305) and the 2 groups were compared. RESULTS: The average age of all patients was 59 years and 63% were women. The average length of hospitalization (KrVD, time period between surgery and discharge) was 4.4 days. The patient groups Reg and Cov19 did not differ with respect to age, gender or KrVD. The total number of CHEs carried out was reduced by 21.4% in the Cov19 group. This affected elective and emergency CHE to the same extent. The length of surgery significantly increased in the Cov19 group from 64 min (SD 34 min) to 71 min (SD 38 min). The number of short and long hospital stays (KrVD 2 or >4 days) significantly increased in the Cov19 group from 4 % to 20 % (short stay, p < 0.01) and from 23 % to 27 % (long stay, p < 0.01). This was particularly observed for patients >70 years old with an increase in long stays from 43 % to 56 % in the Cov19 group. CONCLUSION: The COVID-19 pandemic led to a clear reduction in CHE both for elective and emergency interventions. Furthermore, a significant lengthening of the surgery and hospitalization times could be observed for older patients. The residual consequences of the pandemic could be shortened hospitalization times after uncomplicated CHE and more interventional treatment procedures in complex cases.
