The Nyhus classification of inguinal hernias categorizes a complete indirect hernia with a normal internal ring but large hernial sac extending into the scrotum as:

• A Type I
• B Type II ✓
• C Type IIIa
• D Type IIIb

Explanation

The Nyhus classification: Type I — indirect hernia with normal internal ring (pediatric type); Type II — indirect hernia with dilated internal ring, large sac, floor intact; Type IIIa — direct hernia; Type IIIb — indirect hernia with dilated internal ring and floor defect (pantaloon or scrotal hernia with compromised floor); Type IV — recurrent hernias. A large scrotal sac with normal internal ring corresponds to Type II in the Nyhus system, distinguishing it from the larger floor-defect hernias of Type IIIb.
