Laparoscopic enucleation of pancreatic tumours: a single-institution experience of 66 cases.

BACKGROUND

Laparoscopic enucleation of pancreatic tumours is seemingly a simple procedure, but challenging as the tumour is deeply embedded in the pancreatic parenchyma. Our study reports a single-centre experience for these cases.

METHODS

Cases with a tumour underwent laparoscopic enucleation from January 2014 to March 2020 in our hospital were collected and analysed.

RESULTS

Sixty-six cases were enrolled, including 21 men and 45 women with an average age of 43.6 ± 16.7 years old. The mean size of tumours was 2.7 ± 1.8 cm. The tumours were mainly located at the pancreatic head and neck (63.6%). The most common pathological diagnoses were insulinomas, followed by solid pseudopapillary tumours. Incidences of overall complications and pancreatic fistula (PF, Grade B) were 24.2% and 19.7%, respectively. No patient developed PF (Grade C) or died. Cases were divided into two groups according to whether the tumour was deeply embedded in the pancreas. Compared to the group with a superficial tumour (n = 36), the group with an embedded tumour (n = 30) had a longer operation time and drainage duration and a smaller tumour size (P < 0.05), but did not increase the incidence of complications and PF (Grade B/C).

CONCLUSION

Laparoscopic enucleation of tumours that were deeply embedded in the pancreas was technically feasible and safe.
