Hinchey classification of acute diverticulitis
The original Hinchey classification was based on perioperative surgical finding. It has been later modified by Sher et al.:
Modified Hinchey classification (Sher et al., 1997):
| Stage | Description |
|---|---|
| I | Pericolic abscess |
| IIa | Distant abscess amendable to percutaneous drainage |
| IIb | Complex abscess associated with fistula |
| III | Generalized purulent peritonitis |
Estimate of spleen volume on CT or MRI, splenic index - calculator
This formula can be used to estimate volume of the spleen on crossectional imaging methods by measuring three dimensions - caudocranial (L), maximum size in axial plane (D), and maximum thickness in axial plane (T).
Splenic index = L x D x T
A normal value is considered ≤480.
Volume [mL] = 30 + 0.58 x L x D x T
A normal value is considered between 110 and 340mL
Estimate of liver volume on CT or MRI - calculator
This formula can be used to estimate volume of the liver on crossectional imaging methods by measuring its maximum dimension in three perpendicular axes - caudocranial (CC), latero-lateral (LL), antero-posterior (AP). A normal value is considered <2000mL.
Volume = CC x LL x AP x 0.31
