Table 5 Summary of all the researches

Dong et al. [9]

20 patients were included in day surgery (DS) and 28 patients were applied inpatient surgery (IS). The average hospital day in DSgroup was significantly shorter than in IS group. The average hospital cost in DS group was significantly lower than in IS group.There was no significant difference in the incidence of postoperative complications between two groups

Patel et al. [4]

Only 854 (3.8%) of 22,585 patients that met inclusion criteria were discharged with day surgery. A minimally invasive approach wasthe strongest predictor of early discharge. Readmission rates were not significantly different for two groups.

Drawbert et al. [2]

3879 (7.3%) patients were discharged on day 1, whereas 48951 (92.7%) were discharged after day 1. Factors associated with daysurgery included male sex, higher socioeconomic status, right middle lobectomy, minimally invasive surgery and high-volumecentres.

Linden et al. [7]

1821 patients (3.9%) were discharged on day 1. In multivariable analysis, factors associated with day 1 discharge included age, bodymass index greater than 25, forced expiration value at 1 second, middle or upper lobectomy, minimally invasive technique, andprocedure time. Outpatient 30-day mortality was similar in two groups. Patients discharged on day 1 were not at increased risk ofreadmission.

Dong et al. [6]

136 individuals in DS and 217 individuals in IS. With respect to the postoperative complications (PPCs), no difference between thetwo groups was found. In the DS, a shorter length of stay after surgery and reduced drainage time were found, while the drainagevolume per hour (mL/h) was not notably divergent between the relevant groups. No difference was observed in the cost ofequipment and materials between the two groups. However, the average hospital cost and drug cost of the DS were significantlylower than those of the IS.

Towe et al. [8]

DS after lung resection is multifactorial but is safe among selected patients. Age, lung function, procedure duration, and surgeon allinfluence DS. Complications after DS were rare. Education or enhanced recovery protocols may help overcome this barrier.Standardized pathways would likely help identify low-risk patients for expeditious discharge.

Geraci et al. [10]

134 patients (53%) discharged by day 1. On multivariate analysis, never smokers and segmentectomy were associated with DS.Conversely, decreased baseline performance status and perioperative complications were associated with DS. There were 4readmissions (1.6%), of which one (0.4%) was after day 1 discharge. Patient satisfaction remained high throughout the study period.
