Simplified distal pancreatectomy with the Auto Suture stapler: preliminary clinical observations

The most serious complication following distal pancreatectomy is the development of a pancreatic fistula or subphrenic abscess. These complications are particularly prone to occur following distal pancreatectomy for trauma. The injured pancreas is divided in a contaminated field, often in the presence of hemorrhage and partly devitalized tissues, in which identification and secure closure of the transected pancreatic duct may be difficult. A review of 12 surgical publications describing experience with 234 distal pancreatectomies performed for trauma found the average pancreatic fistula rate to be 13% an in some reports as high as 25% to 30%. In an attempt to decrease the high postoperative fistula rate after distal pancreatectomy, transection of the gland with the autosuture has been investigated. There are at least three theoretical advantages of this technique. The pancreas is transected through healthy tissue, the pancreatic duct is closed securely, and stainless steel sutures are used, which probably are more resistant to the development of infection than other suture material. This report describes a technique of distal pancreatectomy for both trauma surgery and elective surgery with the TA-55 Auto Suture stapler. TA-55 Auto Suture stapler, with 3.5 mm staples, is placed across the mobilized pancreas, and two rows of staggered stainless steel staples are laid down. The gland distal to the stapler then is amputated. At present this technique has been used in a total of 12 cases--four for trauma and eight during elective procedures. One fistula related to pancreatectomy performed with the Auto Suture stapler developed, for a complication rate of 8.3%. This preliminary experience indicates that a more widespread evaluation of this technique is indicated.
