Results

Splenic vein (SV) pressure was measured in 41 patients. Among them, 24 had no SV drainage (13 patients had occluded SV reconstruction, and 11 had SV ligation without an attempt at reconstruction) and were included for the analysis. Sinistral portal hypertension (SPH) was observed in 16 of 24 patients (67%). Most patients with SV pressure after SV clamping>20 mmHg (12/14 [86%]) or DSVP >10 mmHg (10/11 [91%]) developed SPH.

Baseline Characteristics

Patients with pancreatic cancer who underwent PD with PMSC resection and had their SV pressure measured during surgery were included in this retrospective study. Patients who did not have SV pressure measured during surgery and those for whom follow up was inadequate were excluded. Information regarding patients' demographic data, perioperative and postoperative details, and clinicopathologic factors was collected from medical records.

Participant flow

The study protocol was approved by the Institutional Review Board of Cancer Institute Hospital with waived informed consent.

Adverse events

None

Outcome measures

Postoperatively, we examined whether there were any signs of left-sided portal hypertension (such as gastrointestinal varices or gastrointestinal bleeding) in the medium to long term.
It was demonstrated that reconstruction of the splenic vein can be safely performed to prevent left-sided portal hypertension. Additionally, measuring splenic vein pressure allows for the prediction of future left-sided portal pressure and provides valuable guidance in determining whether splenic vein reconstruction should be performed.
