Minimal-access video-assisted retroperitoneal and/or transperitoneal debridement (VARTD) in the management of infected walled-off pancreatic necrosis with deep extension: initial experience from a prospective single-arm study.

ABSTRACT:

Background

The currently preferred minimally invasive approaches have substantially improved outcomes of infected walled-off pancreatic necrosis (iWON). However, iWON with deep extension (iWONde) still poses a tricky challenge for sufficient necrosis evacuation by one stand-alone approach, often requiring repeated interventions. The aim of this study was to assess the effectiveness and safety of a minimal-access video-assisted retroperitoneal and/or transperitoneal debridement (hereafter called VARTD) in the management of iWONde.

Methods

Patients who had developed an iWONde were recruited to receive the VARTD in this prospective single-arm study. The primary efficacy endpoint was clinical improvement up to day 28 after the VARTD, defined as a ≥ 75% reduction in size of necrotic collection (in any axis) on CT and clinical resolution of sepsis or organ dysfunction. The primary safety endpoint was a composite of major complications or death during follow-up. Six-month postdischarge follow-up was available.

Results

Between July 18, 2018, and November 12, 2020, we screened 95 patients with necrotizing pancreatitis; of these, 21 iWONde patients (mean [SD] age, 42.9 [11.7] years; 10 [48%] women) were finally enrolled. The primary efficacy endpoint was achieved by most participants (14/21, 67%). No participants required repeated interventions. The primary safety endpoint occurred in six patients (29%). Except one in-hospital death attributable to repeated intra-abdominal hemorrhage, others were discharged without any major complication.

Conclusions

The VARTD approach appears to have a reasonable efficacy with acceptable complication rates and thus might be an option for improving clinical management of iWONde.

Project description:ObjectiveSeveral studies have demonstrated advantages of the retroperitoneal approach (RP) over the transperitoneal approach (TP) for infrarenal abdominal aortic aneurysm (AAA) repair. A retrospective analysis was performed comparing the outcomes of a TP vs. RP surgical approach for open complex AAA (cAAA) repair and evaluated their relative use over time.MethodsPatients undergoing open repair for intact cAAA (juxtarenal, suprarenal, or type IV thoraco-abdominal aortic aneurysms) between 2011 and 2019 were identified in the National Surgical Quality Improvement Program. The primary outcome was peri-operative death. Secondary outcomes included peri-operative complications and approach use over time. Multivariable adjustment was performed by creating propensity scores and using inverse probability weighted logistic regression.ResultsAmong 1 195 patients identified, 729 (61%) underwent cAAA repair via a TP approach and 466 (39%) via an RP approach. Compared with a TP approach, RP patients more frequently had a supracoeliac clamp position (32% vs. 20%, p < .001) and concomitant renal revascularisation (30% vs. 18%, p < .001). After adjustment, an RP approach was associated with lower odds of peri-operative death (4.0% vs. 7.2%; odds ratio [OR] 0.54; 95% confidence interval [CI] 0.32 - 0.91; p = .022). Furthermore, an RP approach was associated with lower odds of any major complication (24% vs. 30%; OR 0.73; 95% CI 0.56 - 0.94), cardiac complications (4.9% vs. 8.2%; OR 0.60; 95% CI 0.37 - 0.96), wound complications (2.1% vs. 6.0%; OR 0.34; 95% CI 0.17 - 0.64), and post-operative sepsis (0.8% vs. 2.4%; OR 0.37; 95% CI 0.12 - 0.99). The proportion of repairs using an RP approach decreased between 2011 - 2015 and 2016 - 2019 (42% vs. 35%, p = .020), particularly for suprarenal and type IV thoraco-abdominal aneurysms (49% vs. 37%, p = .023).ConclusionIn open cAAA repair, the RP approach may be associated with lower peri-operative mortality and morbidity rates compared with the TP approach. However, it was found that the relative use of the RP approach is decreasing over time, even in suprarenal/type IV thoraco-abdominal aneurysms, and repairs using a supracoeliac clamp. Increased use of the RP approach, when appropriate, may lead to improved outcomes following open cAAA repair.
