Joseph[15]	2015	Emergency laparoscopic cholecystectomy	Patients with continued use of APT (n = 56), including those with preop Plt transfusion (n = 12)	SBL ≥ 100 mL 14.3% in continued ASA vs 9% in control (P = 0.50)	No difference in the rates of overall postop complications (8.9% vs 7.1%, P = 0.80)
			Patients without APT (control, n = 56)		No mortality in both groups
Fujikawa[16]	2017	Emergency cholecystectomy including 106 laparoscopic surgery for acute cholecystitis	Patients with continued use of APT (n = 89)	SBL ≥ 500 mL 12% in continued APT vs 5% in control (P = 0.240)	TE 1.1% in continued APT vs 0% in control (P = 0.37)
			Patients without APT (control, n = 154)	PBC 7% in multiple APT vs 3% in single APT vs 0.6% in control (P = 0.027)	No mortality in both groups
Sakamoto[17]	2017	Laparoscopic cholecystectomy (only elective operation)	Patients with continued single APT (n = 49)	SBL ≥ 200 mL 4.7% in continued APT vs 4.7% in discontinued APT vs 1.5% in control (P = 0.064)	TE 0% in continued APT vs 0.9% in discontinued APT vs 0.2% in control (P = 0.296)
			Patients with discontinuation of APT (n = 106)	PBC 0% in continued APT vs 0.9% in discontinued APT vs 0.2% in control (P = 0.022)	No mortality in any group
			Patients not on APT (control, n = 653)
Yun[18]	2017	Laparoscopic cholecystectomy (elective vs emergency) for acute cholecystitis	Patients with continued use of ATT (almost APT, n = 22)	SBL ≥ 100mL 13.6% in continued ATT vs 22.2% in control (P = 0.613)	One case of TE (2.2%) in control
			Patients with discontinued ATT (almost APT, control, n = 45)		Mortality 4.6% in continued ATT vs 2.2% in control (P > 0.999)
Laparoscopic appendectomy
Chechik[19]	2011	Appendectomy including laparoscopic appendectomy (n = 78)	Patients with continued APT (n = 39)	No difference in SBL or PBC between the groups	No mortality in both groups
			Patients without APT (control, n = 140)
Pearcy[20]	2017	Laparoscopic appendectomy (urgent only)	Patients with continued APT (n = 287)	No difference in SBL (31 g vs 26 g) or blood transfusion rate (1% vs 0%) between the groups	Two cases of TE (MI) in continued APT (0.7%)
			Matched patients without APT (control, n = 287)		No difference in the rates of mortality (1% vs 0%, P = 0.12)
