Enhanced Recovery After Surgery (ERAS) in Pancreatic Surgery: The Surgeon's Point of View.

Pancreatic surgery is complex and associated with higher rates of morbidity and mortality compared to other abdominal surgeries. Over the past decade, the introduction of new technologies, such as minimally invasive approaches, improvements in multimodal treatments, advancements in anesthesia and perioperative care, and better management of complications, have collectively improved patient outcomes after pancreatic surgery. In particular, the adoption of Enhanced Recovery After Surgery (ERAS) recommendations has reduced hospital stays and improved recovery times, as well as post-operative outcomes. The aim of this narrative review is to highlight the surgeon's perspective on the ERAS program for pancreatic surgery, with a focus on its potential advantages for perioperative functional recovery outcomes.

A single-center prospective analysis of the impact of glucose metabolism on pancreatic fistula onset after pancreaticoduodenectomy for periampullary tumors.

BACKGROUND: Glucose impairment notably affects the postoperative course of gastrointestinal surgeries. However, evidence on its impact on clinically relevant pancreatic fistulas(CR-POPFs) after pancreaticoduodenectomy(PD) is lacking. This study evaluates if and how preoperative glucose metabolism affects the development of CR-POPF after PD. METHODS: One hundred and ten consecutive PDs were included. Patients underwent preoperative metabolic profiling using the Oral Glucose Tolerance Test(OGTT) and the hyperinsulinemic euglycemic clamp procedure. Accordingly, patients were categorized as normal glucose tolerant (NGT), impaired glucose tolerant (IGT), diabetic (DM), and longstanding-DM. Receiver operating characteristics(ROC) analyses were performed to determine the values of metabolic features in prediction of CR-POPF. RESULTS: The CR-POPF rate was 36.3 â€‹%(40 patients). NGT patients had a higher CR-POPF rate (51.7 â€‹%) compared to IGT(45.2 â€‹%), DM (15.8 â€‹%), and longstanding-DM (25.8 â€‹%) (p â€‹= â€‹0.03). CR-POPF patients had lower median fasting glucose levels (p â€‹= â€‹0.01) and higher c-peptide values at all OGTT time points (p â€‹< â€‹0.05). Fasting glucose and c-peptide levels had high diagnostic accuracy for CR-POPF (AUC>0.8) and were independent risk factors for CR-POPF (OR: 24.7[95%CI: 3.7-165.3] for fasting glucose; OR: 19.9[95%CI: 3.2-125.3] for c-peptide). CONCLUSION: Normoglycemia and normal beta cell function may be risk factors for CR-POPF after PD. Fasting glucose and c-peptide levels effectively predicted CR-POPF development following PD.

Resection Margin Status and Long-Term Outcomes after Pancreaticoduodenectomy for Ductal Adenocarcinoma: A Tertiary Referral Center Analysis.

The influencing role of resection margin (R) status on long-term outcomes, namely overall (OS) and disease-free survival (DFS), after pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) is not still clear. The aim of this study is to evaluate the prognostic impact of R status after PD and to define tumor characteristics associated with a positive resection margin (R1). All PDs for PDAC performed between 2012 and 2023 were retrospectively enrolled. The effect of R status, patient clinico-demographic features, and tumor features on OS and DFS were assessed. One-hundred and sixty-seven patients who underwent PD for PDAC were included in the study. R0 was achieved in 105 cases (62.8%), while R1 was evidenced in 62 patients (37.1%). R1 was associated with a decreased OS (23 (13-38) months) as compared to R0 (36 (21-53) months) (p = 0.003). Similarly, DFS was shorter in R1 patients (10 (6-25) months) as compared to the R0 cohort (18 (9-70) months) (p = 0.004), with a consequent higher recurrence rate in cases of R1 (74.2% vs. 64.8% in the R0 group; p = 0.04). In the multivariate analysis, R1 and positive lymph nodes (N+) were the only independent influencing factors for OS (OR: 1.6; 95% CI: 1-2.5; p = 0.03 and OR: 1.7; 95% CI: 1-2.8; p = 0.04) and DFS (OR: 1.5; 95% CI: 1-2.1; p = 0.04 and OR: 1.8; 95% CI: 1.1-2.7; p = 0.009). Among 111 patients with N+ disease, R1 was associated with a significantly decreased DFS (10 (8-11) months) as compared to R0N+ patients (16 (11-21) months) (p = 0.05). In conclusion, the achievement of a negative resection margin is associated with survival benefits, particularly in cases of N1 disease. In addition, R0 was recognized as an independent prognostic feature for both OS and DFS. This further outlines the relevant role of radical surgery on long-term outcomes.

Prolonged pre-firing pancreatic compression with linear staplers in distal pancreatectomy: a valuable technique for post-operative pancreatic fistula prevention.

PURPOSE: Post-operative pancreatic fistula (POPF) remains the main complication after distal pancreatectomy (DP). The aim of this study is to evaluate the potential benefit of different durations of progressive stapler closure on POPF rate and severity after DP. METHODS: Patients who underwent DP between 2016 and 2023 were retrospectively enrolled and divided into two groups according to the duration of the stapler closure: those who underwent a progressive compression for < 10 min and those for ≥ 10 min. RESULTS: Among 155 DPs, 83 (53.5%) patients underwent pre-firing compression for < 10 min and 72 (46.5%) for ≥ 10 min. As a whole, 101 (65.1%) developed POPF. A lower incidence rate was found in case of ≥ 10 min compression (34-47.2%) compared to < 10 min compression (67- 80.7%) (p = 0.001). When only clinically relevant (CR) POPFs were considered, a prolonged pre-firing compression led to a lower rate (15-20.8%) than the < 10 min cohort (32-38.6%; p = 0.02). At the multivariate analysis, a compression time of at least 10 min was confirmed as a protective factor for both POPF (OR: 5.47, 95% CI: 2.16-13.87; p = 0.04) and CR-POPF (OR: 2.5, 95% CI: 1.19-5.45; p = 0.04) development. In case of a thick pancreatic gland, a prolonged pancreatic compression for at least 10 min was significantly associated to a lower rate of CR-POPF compared to < 10 min (p = 0.04). CONCLUSION: A prolonged pre-firing pancreatic compression for at least 10 min seems to significantly reduce the risk of CR-POPF development. Moreover, significant advantages are documented in case of a thick pancreatic gland.
