Computed tomography-guided splanchnic nerve neurolysis outcomes by tumor site in unresectable pancreatic cancer: A single-center retrospective cohort study

Table 1 Patient and procedural characteristics at the initial computed tomography-guided neurolytic splanchnic nerve block

Characteristic	All patients (n = 22)	Head (n = 9)	Body/tail (n = 13)	Technical success (n = 17)	Technical failure (n = 5)
Age (years)	60.5 (56.5-64.5)	61 (53-63)	60 (58-65)	60 (58-63)	63 (44-70)
Male sex	16 (72.7)	6 (66.7)	10 (76.9)	11 (64.7)	5 (100.0)
PL I only	5 (22.7)	1 (11.1)	4 (30.8)	3 (17.6)	2 (40.0)
PL II only	3 (13.6)	3 (33.3)	0 (0.0)	2 (11.8)	1 (20.0)
Both PL I and PL II	14 (63.6)	5 (55.6)	9 (69.2)	12 (70.6)	2 (40.0)
Recorded metastatic or locally invasive disease	17 (77.3)	7 (77.8)	10 (76.9)	15 (88.2)	2 (40.0)
90% alcohol mixture volume (mL)	10.6 ± 3.5	9.0 ± 1.7	11.7 ± 4.1	11.5 ± 3.3	7.4 ± 2.5

Data are presented as n (%), median (interquartile range), or mean ± SD, as indicated. Only the initial procedure was included for each patient. PL I was defined as the pancreatic head nerve plexus I, extending from the right celiac ganglion to the posterior pancreatic head; PL II was defined as the pancreatic head nerve plexus II, connecting the superior mesenteric nerve plexus with the uncinate process.
