Abstract Background Surgical site infections are an important burden of pancreatic surgery, prolonging hospitalization and delaying adjuvant treatment. The aim of this study was to compare negative pressure wound therapy with standard sterile dressing in terms of the prevention of non–organ-space surgical site infection (superficial and deep surgical site infection) in the high-risk setting. Methods The trial was conducted at the University of Verona Hospital Trust, Verona, Italy, from July 25, 2018, through October 10, 2019, among adults undergoing surgery for periampullary neoplasms. Only patients at high-risk for surgical site infection based on body mass index, diabetes, steroids, neoadjuvant therapy, American Society of Anesthesiologists score, Charlson comorbidity index, duration of surgery, and blood loss were included and randomized. Results A total of 351 patients were screened, 100 met the inclusion criteria and were 1:1 allocated in the 2 arms. The difference in terms of non–organ-space surgical site infection comparing negative pressure wound therapy with standard sterile dressing was not significant (10.9 vs 12.2%, risk ratio [RR] 1.144, confidence interval [CI] 95% 0.324–4.040, P = 1.000). Hematomas (4.3 vs 2%, RR 1.565, CI 95% 0.312–7.848, P = .609) and organ-space infections (46.7 vs 43.8%, RR 1.059, CI 95% 0.711–1.576, P = .836) were similar. Negative pressure wound therapy prevented the development of seromas (0 vs 12.2%, RR 0.483, CI 95% 0.390–0.599, P = .027). The aesthetic result assessed on postoperative day 7 was better in the negative pressure wound therapy group (visual analogue scale, 8 vs 7, P = .029; Stony Brook Scar Evaluation Scale, 3.2 vs 2.5, P = .009), but it was no more evident on postoperative day 30 after a total number of 23 dropouts. Conclusion Compared with standard sterile dressing, negative pressure wound therapy is not associated with an improved rate of non–organ-space surgical site infection after surgery for periampullary neoplasms in patients at high risk for surgical site infection. Additional studies will help identify the population that could benefit most from this intervention.

BACKGROUND: Surgical-site infection (SSI) increases treatment costs, duration of hospital stay and readmission rate after pancreatic surgery. This study aimed to assess whether a wound protector could reduce the risk of superficial incisional SSI after pancreatoduodenectomy. METHODS: This RCT included patients undergoing pancreatoduodenectomy at Verona University Hospital, between 2017 and 2018. The experimental group had a dual-ring wound protector, whereas the control group had standard surgic...

OBJECTIVE: The aim of this study was to evaluate the efficacy of iNPWT for the prevention of postoperative wound complications such as SSI. SUMMARY OF BACKGROUND DATA: The 2016 WHO recommendation on the use of iNPWT for the prevention of SSI is based on low-level evidence, and many trials have been published since. Preclinical evidence suggests that iNPWT may also prevent wound dehiscence, skin necrosis, seroma, and hematoma. METHODS: PubMed, EMBASE, CINAHL, and CENTRAL were searched for randomi...

OBJECTIVE: Determine if negative pressure wound therapy (NPWT) reduces surgical site infection (SSI) in primarily closed incision after open and laparoscopic-converted colorectal surgery. BACKGROUND: SSIs after colorectal surgery are a common cause of morbidity. The prophylactic effect of NPWT has not been established. We undertook this study to evaluate if, among patients undergoing open colorectal resection, NPWT, as compared with standard postoperative dressings, is associated with a reductio...

Background Pancreaticoduodenectomy is historically associated with incisional surgical site infection (iSSI) rates between 15% and 20%. Prospective studies have been mixed with respect to the benefit of individual interventions directed at decreasing iSSI. We hypothesized that the application of a perioperative bundle during pancreaticoduodenectomy would decrease the rate of iSSIs significantly. Methods An initial cohort of 150 consecutive post-pancreaticoduodenectomy patients were assessed with...

Surgical site infection (SSI) and incisional hernia are common complications after major pancreatectomy. We investigated the effects of negative pressure wound therapy (NPWT) on short- and long-term wound outcomes in patients undergoing pancreatectomy. A randomized controlled trial comparing the effect of NPWT with standard surgical dressing (SSD) on wounds was performed in 265 patients undergoing open gastrointestinal resections from 2012 to 2016. We performed a subset analysis of 73 patients w...

Abstract Major hepatobiliary and pancreatic (HP) surgeries are complex procedures associated with a high incidence of surgical site infection (SSI) and are commonly performed in patients with cancer in Japan. This study was performed to investigate the risk factors for SSI, including incisional and organ/space SSI, in HP surgery. The following procedures were included in the study: hepatectomy with and without biliary tract resection, pancreatectomy [pancreaticoduodenectomy (PD), others], and op...

Abstract Background Surgical site infections (SSIs) are common following pancreatectomy and associated with significant morbidity and economic burden. We sought to identify distinct predictors for superficial versus deep/organ space SSIs and their effects on surgical outcomes. Methods ACS-NSQIP targeted pancreatectomy 2014 and 2015 databases were queried. Univariate and multivariate models were developed for both types of SSI, length of stay (LOS), and readmission. Costs were estimated based on ...

Abstract Background Despite improvements in the perioperative care, the morbidity rate after pancreaticoduodenectomy (PD) is still higher than 50%. The aim of this study was twofold: first, to assess the correlation between preoperative rectal swab (RS) and intraoperative bile cultures; to examine the impact of RS isolates on postoperative course after PD. Methods An observational study was conducted analyzing all consecutive PD performed from January 2015 to July 2016. Based on the positivity/n...
