Abstract

BACKGROUND:

Non-functional endocrine pancreatic tumours (NPT) of more than 2 cm have an increased risk of malignancy. The aim of the present study was: (i) to define the guidelines for laparoscopic enucleation (LapEn) in patients with a non-functional NPT ≤3 cm in diameter; (ii) to evaluate pancreas-related complications; and (iii) to present the long-term outcome.

METHODS:

Between April 1998 and September 2010, 30 consecutive patients underwent laparoscopic surgery for a non-functional NPT (median age 56.5 years, range 44-83). Only 13 patients with tumours ≤3 cm in size underwent LapEn. Local lymph node dissection to exclude lymph node involvement was performed in all patients.

RESULTS:

The median tumour size, operative time and blood loss were 2.8 cm (range 2.8-3), 130 min (range 90-280) and 220 ml (range 120-300), respectively. A pancreatic fistula occurred in five patients: International Study Group of Pancreatic Fistula (ISGPF) A in two patients and ISGPF B in three patients. The median follow-up was 48 months (12-144). Three patients with well-differentiated carcinoma are free of disease 2, 3 and 4 years after LapEn and a regional lymphadenectomy. One patient, 5 years after a LapEn, presented with lymph node and liver metastases.

CONCLUSIONS:

The present study confirms the technical feasibility and acceptable morbidity associated with LapEn. Intra-operative lymph node sampling and frozen-section examination should be performed at the time of LapEn; when a malignancy is confirmed, oncologically appropriate lymph node dissection should be performed.
