Venting intraluminal drains in pancreaticoduodenectomy

The utility of placing biliary, pancreatic, or enteric "venting"tubes (externally draining devices traversing the bowel or bile duct that have their distal tip located intraluminally near the biliary or pancreatic anastomosis) when performing a pancreaticoduodenectomy has received little attention to date. We hypothesize that these venting tubes do not decrease the morbidity or mortality associated with pancreaticoduodenectomy and may actually be a source of additional morbidity. To characterize our use of and the effect of these drains, we retrospectively analyzed 136 pancreaticoduodenectomies (127 partial, 9 total) performed over a 24-month period. Venting drain use, drain type and size, drain location, duration of intubation, hospital course, and postoperative complications were noted. Venting tubes were used in 80 patients (59%). The use of these drains had no significant relationship to postoperative length of stay, the development of major complications, overall morbidity, or mortality (P>0.05). Such drains also did not significantly shorten the length of hospital stay (P>0.05) or improve outcome when available to augment local control following luminal leak (n = 6) or regional abscess (n = 7). These drains were removed at a median interval of 29 days postoperatively (range 6 to 77 days). Seven patients had complications that were directly related to the venting drain; four of these patients had a documented intra-abdominal luminal leak from the site of drain removal, whereas the other three were hospitalized for presumed leakage secondary to immediate, severe abdominal pain following removal of the drain. These seven patients were elderly (mean age 70 years) and often harbored pancreatic ductal carcinoma (n = 6). Intraluminal drains afford no distinct advantage in terms of shortening the postoperative length of stay, decreasing operative morbidity and mortality, or improving local control with regional sepsis in pancreaticoduodenectomies. Furthermore, they may add an additional source of morbidity and we no longer employ them routinely.
