Systematic review and meta-analysis of prophylactic abdominal drainage after pancreatic resection

Figure 1 Flow diagram of literature search and selection.

Figure 2 Forest plots of clinical outcomes in patients with prophylactic drainage vs those without prophylactic drainage after pancreatic resection. The effect of prophylactic abdominal drainage on A: Mortality; B: Morbidity; C: Postoperative pancreatic fistula (POPF); D: Clinically relevant pancreatic fistula (CR-PF); E: Abdominal abscess; F: Interventional radiology drainage; G: Reoperation; and H: Length of hospital stay.

Figure 3 Forest plots of subgroup analysis of patients who underwent pancreaticoduodenectomy. For patients who underwent pancreaticoduodenectomy (PD), the effect of prophylactic abdominal drainage on A: Mortality; B: Morbidity; C: Postoperative pancreatic fistula (POPF); D: Clinically relevant pancreatic fistula (CR-PF); E: Abdominal abscess; F: Interventional radiology drainage; G: Reoperation; and H: Length of hospital stay.

Figure 4 Forest plots of subgroup analysis of patients who underwent distal pancreatectomy. For patients who underwent distal pancreatectomy (DP), the effect of prophylactic abdominal drainage on A: Morbidity; B: Postoperative pancreatic fistula (POPF); C: Interventional radiology drainage; D: Reoperation; and E: Length of hospital stay.
