Self-reported open cholecystectomy training, practice, and confidence in the laparoscopic era: An international convenience-sample survey

Table 4 Cumulative open cholecystectomy volume as primary surgeon, stratified by years of practice and by current role (n = 391)

Stratum	0-10	11-30	31-50	51-100	> 100
By years of practice
1-5 years (n = 60)	26 (43.3)	11 (18.3)	8 (13.3)	6 (10.0)	9 (15.0)
5-10 years (n = 46)	9 (19.6)	9 (19.6)	8 (17.4)	12 (26.1)	8 (17.4)
10-15 years (n = 43)	5 (11.6)	9 (20.9)	4 (9.3)	6 (14.0)	19 (44.2)
15-20 years (n = 32)	1 (3.1)	3 (9.4)	4 (12.5)	4 (12.5)	20 (62.5)
More than 20 years (n = 104)	3 (2.9)	2 (1.9)	3 (2.9)	11 (10.6)	85 (81.7)
Not answered (n = 106)	72 (67.9)	17 (16.0)	9 (8.5)	2 (1.9)	6 (5.7)
By current role
Residents (n = 105)	71 (67.6)	17 (16.2)	7 (6.7)	3 (2.9)	7 (6.7)
Fellows (n = 16)	3 (18.8)	3 (18.8)	2 (12.5)	1 (6.3)	7 (43.8)
Attendings (n = 270)	42 (15.6)	31 (11.5)	27 (10.0)	37 (13.7)	133 (49.3)

Values are n (%) within each stratum. No statistical comparison was performed. The not-answered stratum corresponds to respondents who did not answer the item on years of practice, of whom 92 were residents, 9 fellows and 5 attendings. Strata are approximate because the years-of-practice options overlap at their limits.
