Treatment of pancreatic pseudocysts in line with D’Egidio’s classification

Table 1 Size of pseudocyst and anatomy of the pancreatic duct of patients.

Group	Number of Patients (n)	Average size of cyst (cm)	Duct stricture1	Cyst-duct communication1
I	37	7.2 (2-23)	0/12	1/12
II	24	4.4 (2-12)	0/15	7/15
III	12	10.5 (5-25)	8/8	7/8

¹ The number before the slash indicates the number of cases receiving ERCP or sonogram, and that after the slash is the positive cases identified.

Table 2 Treatment approaches for pancreatic pseudocysts.

Group	Methods of treatment (n)
	Percutaneous drainage	External drainage	Internal drainage	Distal pancreatectomy
I	11	10	6	0
II	5	4	10	2
III	0	2	5	5

Table 3 Rate of recurrence of pseudocyst and complications after treatment in 3 groups.

Group	Methods of treatment
	Percutaneous drainage	External drainage	Internal drainage	Distal pancreatectomy
I	2, 0	4, 2	2, 0	-, -
II	3, 0	1, 1	0, 1	0, 0
III	-, -	1, 1	0, 1	0, 1

In each pair of numbers listed in the table, the former indicates the number of patients who had complications, and the latter is the number of patients who had recurrence.
