Outcome of endotherapy for pancreas divisum in patients with acute recurrent pancreatitis

Table 2 Follow-up results in 33 patients with pancreas divisum and previous and recent recurrent acute pancreatitisaccording to dilatation or non-dilatation of the main pancreatic duct detected at the time of the enrollment into the study n (%)

	Dorsal duct	AP recurrences	EUS signs of CP
Previous RAP (14 pts)	Dilated (6 pts)	0	4 (66.7)1
	Non-dilated (8 pts)	0	5 (62.5)
	Total	0b	9 (64.3)2
Recent RAP (19 pts)	Dilated (11 pts)	2 (18.2)3	7 (63.6)3
	Non-dilated (8 pts)	3 (37.5)	4 (50.0)
	Total	5 (26.3)	11 (57.9)4

¹Dilated and non-dilated in the previous RAP group: P = NS;

²Previous and recent RAP: P = NS;

^bP < 0.05, endotherapy vs main pancreatic duct dilatation;

³Dilated and non-dilated in the recent RAP group: P = NS;

⁴All five patients with AP recurrences during follow-up developed CP. AP: Acute pancreatitis; EUS: Endoscopic ultrasonography; CP: Chronic pancreatitis; RAP: Recurrent acute pancreatitis; NS: Not significant.
