Efficacy of preoperative biliary drainage in malignant obstructive jaundice: a meta-analysis and systematic review.

Moole H, Bechtold M, Puli SR - World J Surg Oncol (2016)

Bottom Line: Pooled number of major adverse effects was lower in the PBD group at 10.40 (95 % CI = 9.96 to 10.83) compared to 15.56 (95 % CI = 15.06 to 16.05) in the DS group.Subgroup analysis comparing internal PBD to DS group showed lower odds for major adverse events (odds ratio, 0.48 with 95 % CI = 0.32 to 0.74).Length of hospital stay and mortality rate were comparable in both the groups.

ABSTRACT

Background: In patients requiring surgical resection for malignant biliary jaundice, it is unclear if preoperative biliary drainage (PBD) would improve mortality and morbidity by restoration of biliary flow prior to operation. This is a meta-analysis to pool the evidence and assess the utility of PBD in patients with malignant obstructive jaundice. The primary outcome is comparing mortality outcomes in patients with malignant obstructive jaundice undergoing direct surgery (DS) versus PBD. The secondary outcomes include major adverse events and length of hospital stay in both the groups.

Methods: Studies using PBD in patients with malignant obstructive jaundice were included in this study. For the data collection and extraction, articles were searched in MEDLINE, PubMed, Embase, Cochrane Central Register of Controlled Trials & Database of Systematic Reviews, etc. Pooled proportions were calculated using both Mantel-Haenszel method (fixed effects model) and DerSimonian-Laird method (random effects model).

Results: Initial search identified 2230 reference articles, of which 204 were selected and reviewed. Twenty-six studies (N = 3532) for PBD in malignant obstructive jaundice which met the inclusion criteria were included in this analysis. The odds ratio for mortality in PBD group versus DS group was 0.96 (95 % CI = 0.71 to 1.29). Pooled number of major adverse effects was lower in the PBD group at 10.40 (95 % CI = 9.96 to 10.83) compared to 15.56 (95 % CI = 15.06 to 16.05) in the DS group. Subgroup analysis comparing internal PBD to DS group showed lower odds for major adverse events (odds ratio, 0.48 with 95 % CI = 0.32 to 0.74).

Conclusions: In patients with malignant biliary jaundice requiring surgery, PBD group had significantly less major adverse effects than DS group. Length of hospital stay and mortality rate were comparable in both the groups.

Mentions: Subgroup analysis was also performed on studies that compared percutaneous transhepatic PBD and DS in patients with malignant biliary strictures. Four studies [28, 29, 43, 44] were included in this analysis. The total number of patients in this subgroup (n) was 182, with 93 patients in the percutaneous transhepatic PBD group. The median age of patients in this subgroup was 62 years, with predominantly male population (61 %). The pooled odds ratio for mortality in the percutaneous transhepatic PBD group compared to the DS group was 0.98 (95 % CI = 0.46 to 2.10). I2 (inconsistency) = 21.4 % (95 % CI = 0 % to 74.2 %). Egger, bias = −2.98 (95 % CI = −5.80 to −0.15) p = 0.04. Figure 7 is a forest plot that displays the same data. Odds ratio for major adverse events in percutaneous transhepatic PBD group versus DS group was 1.50 (95 % CI = 0.85 to 2.65). I2 (inconsistency) = 88.5 % (95 % CI = 68.8 to 93.8 %). Egger, bias = 3.70 (95 % CI = −18.41 to 25.81) p = 0.54. Due to the limited data available, we were not able to generate any meaningful results in regard to the length of hospital stay and individual adverse events.Fig. 7
