[Central segments resections in primary liver neoplasms--three clinical cases]

Area of Science:

• Hepatobiliary surgery
• Surgical oncology

Background:

• Central paramedian hepatic resections are technically challenging and rarely reported.
• Primary hepatic neoplasms in central segments pose unique surgical challenges.

Observation:

• Three cases of primary hepatic neoplasms (two cancers, one sarcoma) underwent central hepatic sector resection.
• The procedure involved liver mobilization, vascular isolation (Pringle maneuver), and careful dissection of hilar structures.
• Intraoperative assessment guided the extent of resection based on neoplastic involvement.

Findings:

• No disease recurrence was observed during 5 to 24 months of follow-up.
• Hepatic resection for central segments can be performed with low morbidity.

Implications:

• Accurate preoperative diagnosis and assessment of vascular involvement are crucial for successful outcomes.
• Central hepatic resections can be performed with confidence, comparable to other major surgical procedures.
