	Study details	Conversion	Blood loss	Transfusion rate	Clavien–Dindo
Current study	Open (11.1%) and laparoscopic (88.9%) PN with Hemopatch®; case series of n = 45	0% laparoscopic to open PN	Median 200 ml	8.9%	1: 2.2% 2: 4.4% 3: 13.3% 4–5: 0%
Imkamp et al. [13]	Laparoscopic PN with Hemopatch®; case series of n = 7	0% laparoscopic to open PN	Median 325 ml		No postoperative complication
Van Poppel et al. [4]	PN (49.5%) and RN (50.5%); prospective trial of n = 541		“Severe hemorrhage” PN 3.1%; blood loss < 500 ml PN 87.2%		3: PN 4.4%
