Posterior approach to Calot’s triangle in situs inversus totalis: A case report and review of literature

Table 2 As-reported preoperative investigations in reported situs inversus totalis-laparoscopic cholecystectomy cases (n = 110), n (%)

Variables	Value
Ultrasonography	98 (89.1)
Abdominal computed tomography	43 (39.1)
Magnetic resonance imaging	6 (5.5)
Magnetic resonance cholangiopancreatography	14 (12.7)
Chest radiography	76 (69.1)
Preoperative endoscopic retrograde cholangiopancreatography	4 (3.6)

Modalities were counted only when explicitly reported; non-mention was coded as “not reported” (not “not performed”). Percentages therefore reflect reporting frequency rather than true utilization. Multiple modalities could be reported per case; category totals may exceed 110. Magnetic resonance imaging and magnetic resonance cholangiopancreatography were coded separately according to explicit wording in the original reports.
