[Surgical treatment of pancreatic insulinoma by laparoscopy].

OBJECTIVE

To evaluate the safety and outcome of laparoscopic insulinoma resection.

METHODS

Twenty-five patients with insulinoma were admitted and divided into two groups: laparoscopic group (10 patients) and laparotomy group (15 patients). All tumors of two groups were located at the body or tail of pancreas preoperatively by abdominal CT and digital subtraction angiography (DSA). Laparoscopic enucleation was performed for patients in laparoscopic group, open enucleation was performed for patients in laparotomy group. There were no differences in preoperative location and size of tumors between two groups. Statistical method was used to compare the discrepancy from operation time, the volume of blood loss, hospital stay and morbidity of complication between two groups.

RESULTS

There were no discrepancies from operation time, blood loss, hospital stay after operation between two groups (P > 0.05). However, one case of pancreatic leakage developed in laparoscopic group, comparably, 3 cases of pancreatic leakage, 2 cases of celiac sepsis and 5 cases of fluid accumulation in thoracic cavity developed in laparotomy group. There were significant discrepancies in morbidity of complication between two groups.

CONCLUSIONS

Laparoscopic resection of pancreatic insulinoma is safe and feasible for tumors located at the body or tail of the pancreas. Its application for tumors located at the pancreatic head needs further evaluation.
