The hepatic and pancreatic tumour resection risk factors for surgical site wound infections: A meta-analysis

A meta-analysis was conducted to measure hepatic and pancreatic tumour resection (HPTR) risk factors (RFs) for surgical site wound infections (SSWIs). A comprehensive literature inspection was conducted until February 2023, and 2349 interrelated investigations were reviewed. The nine chosen investigations included 22 774 individuals who were in the chosen investigations' starting point, 20 831 of them were with pancreatic tumours (PTs), and 1934 with hepatic tumours (HTs). Odds ratio (OR) and 95% confidence intervals (CIs) were used to compute the value of the HPTR RFs for SSWIs using dichotomous and continuous approaches, and a fixed or random model. HT patients with biliary reconstruction had significantly higher SSWI (OR, 5.81; 95% CI, 3.42-9.88, P < .001) than those without biliary reconstruction. Nevertheless, there was no significant difference between individuals with PT who underwent pancreaticoduodenectomy and those who underwent distal pancreatectomy in SSWI (OR, 1.63; 95% CI, 0.95-2.77, P = .07). HT individuals with biliary reconstruction had significantly higher SSWI compared with those without biliary reconstruction. Nevertheless, there was no significant difference between PT individuals who underwent pancreaticoduodenectomy and those who underwent distal pancreatectomy in SSWI. However, owing to the small number of selected investigations for this meta-analysis, care must be exercised when dealing with its values.

Automated summary

A meta-analysis was conducted to evaluate risk factors for surgical site wound infections (SSWIs) in hepatic and pancreatic tumour resection (HPTR). A total of 2349 interrelated investigations were reviewed, and 9 investigations with 22,774 individuals were included. The results showed that HT patients with biliary reconstruction had significantly higher SSWI risk, while there was no significant difference in SSWI between PT individuals who underwent different types of surgeries. However, caution should be exercised due to the limited number of selected investigations for this meta-analysis.
