Abstract
Background: Although several trials have been conducted, the management of liver drains remains controversial among HPB surgeons. We conducted a world-wide survey to define actual clinical drain practices adopted by liver surgeons in the EA-HPBA, A-HPBA and AP-HPBA communities. Methods: An open survey consisting of 30 questions was prepared and then published on Google – Form, which was then delivered by email to members of the three major chapters of the international hepato-pancreato-biliary association (IHPBA). Results: 191 HPB surgeons responded to the web-survey. Twenty (10.5%) respondents were from the Asian-Pacific region, while 15 (7.9%) were from North America, 13 (6.8%) from South America and 143 (74.9%) from Europe and Africa. One hundred-twelve surgeons (58.6%) reported routine use of abdominal drains liver resection. Eighty-eight (46.1%) respondents responded that drain removal was driven by low volume and low bilirubin levels in the drains; 85 (44.5%) surgeons usually consider removal of the drain on 2-3 post-operative days (POD). In case of minor liver resection, 97 (50.8%) surgeons reported using drains only in select cases. When a major resection (>=3 liver segments) is performed, 134 (70.2%) surgeons preferred to always use a drain. Among patients with cirrhosis, 87 (45.5%) surgeons reported the routine use of drains, while 84 (44.0%) respondents considered drains only selectively. The lack of drains was most prevalent among surgeons from North America (12, 80%); in contrast, 14 (70.0%) surgeons in Asian-Pacific region, 87 (60.8%) in Europe and Africa and 8 (61.5%) in South America were more inclined to employ liver drains routinely (p=0.014). Among surgeons whose practice is mostly mini-invasive liver surgery (n=31), 23 (74.2%) reported draining only in selected cases, while the proportion of surgeons who use drains selectively among surgeons who performed mainly open liver resections was lower (n=56, 35.0%)(p<0.001). Conclusion: Despite several RCTs, use of drains at the time of liver resection remains highly variable. In particular, surgeons from North America, as well as surgeons who predominantly perform minimally-invasive hepatectomy, are much less likely to employ abdominal drains at the time of liver resection.
