Pancreas-preserving duodenal resections vs pancreatoduodenectomy for groove pancreatitis. Should we revisit treatment algorithm for groove pancreatitis?

Table 1 Short- and long- term results of cystic dystrophy of the duodenal wall treatment (2004-2019)

Type of treatment	n	1Morbidity n (%)	Full pain control, n (%)	Steatorrhea, n (%)	New DM, n (%)
Conservative	12	5 (42%)	5 (42)	4 (33)	6 (50)
Draining OP	8	1/1 (12.5/12.5%)	2 (25)	2 (25)	2 (25)
DPPHR	6	1/2 (17/34%)	2 (33)
PD	44	12/7 (27/16%)	37 (84)	6 (14)	12 (31)
PPDR	15	4/1 (27/7%)	14 (93)

¹Postoperative complications are shown as minor/major (Dindo-Clavien I-II/III-IV).

DPPHR: Duodenum-preserving pancreatic head resection; PD: Pancreatoduodenectomy; PPDR: Pancreas-preserving duodenal resection; DM: Diabetes mellitus; Draining OP: Pancreatico- and/or cystoenterostomy.
