The lasso technique for laparoscopic distal pancreatectomy.
BACKGROUND
Laparoscopic distal pancreatectomy with or without splenectomy is becoming an acceptable alternative to open resection for selected pancreatic lesions. One of the difficulties with this approach is manipulating the pancreas with laparoscopic instruments to avoid unnecessary injury to the pancreas, and yet obtain adequate margins. The described technique accomplishes these goals.


METHODS
Data from all patients who underwent laparoscopic distal pancreatectomy (always with splenectomy) were reviewed for age, gender, laparoscopic completion of the resection, postoperative complications, length of hospital stay, and pathology. The essential component of the technique is use of a Penrose drain around the neck or proximal body of the pancreas as a "lasso" for atraumatic manipulation. This technique is described in detail.


RESULTS
A total of 11 patients have undergone laparoscopic distal pancreatectomy with splenectomy using the lasso technique. Two patients (18%) underwent conversion to an open laparotomy: the because of bleeding from the pancreatic parenchyma and the other due to local invasion of a pancreatic adenocarcinoma. The average operating time was 162 +/- 39 min, and the median length of hospital stay was 3 days. There were two (18%) pancreatic leaks, both of which were treated conservatively with resolution. Pathologic examination, found six cystic neoplasms, two neuroendocrine tumors, two masses of chronic pancreatitis, and one adenocarcinoma.


CONCLUSIONS
The lasso technique simplifies intraoperative manipulation of the pancreas during laparoscopic distal pancreatectomy. It allows for safe manipulation of the pancreas and may expand the indications for the laparoscopic approach to pancreatic resection.
