In the article by Kurata M, Iwashita Y, Ohyama T, Endo I, Hibi T, Umezawa A, et al. Assembling a library of typical surgery video clips to construct a system for assessing the surgical difficulty of laparoscopic cholecystectomy. J Hepatobiliary Pancreat Sci. 2021;28:255–62. https://doi.org/10.1002/jhbp.871

There was error in Table 1 of the article. The updated Table 1 is below:

TABLE 1. Intraoperative findings that potentially contribute to surgical difficulty

Item
A. Factors related to inflammation of the gallbladder
(a) Appearance around the gallbladder
1. Fibrotic adhesions around the gallbladder due to inflammation
2. Partial scarring adhesions around the gallbladder
3. Diffuse scarring adhesions around the gallbladder
(b) Appearance of the Calot’s triangle area
4. Sparse fibrotic change in the Calot’s triangle area
5. Dense fibrotic change but no scarring in the Calot’s triangle area
6. Partial scarring in the Calot’s triangle area
7. Diffuse scarring in the Calot’s triangle area
(c) Appearance of the gallbladder bed
8. Sparse fibrotic change in the gallbladder bed
9. Dense fibrotic change in the gallbladder bed
10. Partial scarring in the gallbladder bed
11. Diffuse scarring in the gallbladder bed
(d) Additional findings of the gallbladder and its surroundings
12. Edematous change around the gallbladder/in the Calot’s triangle area / in the gallbladder bed
13. Easy bleeding at dissection around the gallbladder/in the Calot’s triangle area / in the gallbladder bed
14. Necrotic changes around the gallbladder/in the Calot’s triangle area/in the gallbladder bed
15. Non-iatrogenic, perforated gallbladder wall and / or abscess formation towards the abdominal cavity noted during adhesiolysis around the gallbladder
16. Abscess formation towards the liver parenchyma
17. Cholecysto-enteric fistula
18. Cholecysto-choledochal fistula (included in the expanded classification of Mirizzi syndrome)
19. Impacted gallstone in the confluence of the cystic, common hepatic, and common bile duct (included in the expanded classification of Mirizzi syndrome)
B. Intra-abdominal factors unrelated to inflammation
20. Excessive visceral fat
21. Inversion of the gallbladder in the gallbladder bed due to liver cirrhosis
22. Collateral vein formation due to liver cirrhosis
23. Non-inflammatory (physiological) adhesion around the gallbladder
24. Anomalous bile duct
25. Gallbladder neck mounting on the common bile duct

The author apologizes for this error.
