(1) Background: The modified Whipple procedure, or pylorus-preserving pancreaticoduodenectomy, is a complex surgical intervention used to treat pancreatic head tumors. While preserving digestive function, it is associated with significant perioperative risks. This study explores the clinical, immunological, and microbiome-related factors influencing postoperative complications, focusing on the interplay between patient comorbidities, systemic inflammation, and gut dysbiosis. (2) Methods: A retrospective analysis was conducted on 123 patients undergoing the modified Whipple procedure for pancreatic head tumors. Patients were categorized into two groups based on the occurrence of significant postoperative complications (Group A: with complications; Group B: without complications). Data on demographics, comorbidities, inflammatory markers (CRP, IL-6, procalcitonin), and gut microbiome composition were collected. Microbial diversity was evaluated using the Shannon Index, and logistic regression was performed to identify independent predictors of complications. (3) Results: Patients in Group A had a significantly higher prevalence of diabetes mellitus (43.1% vs. 20.8%; p = 0.02) and cardiovascular disease (35.3% vs. 13.9%; p = 0.01). Elevated inflammatory markers (CRP ≥ 40 mg/L, IL-6 ≥ 30 pg/mL, procalcitonin ≥ 0.5 ng/mL) were strongly associated with higher complication rates. Microbiome analysis indicated dysbiosis in Group A, with reduced Lactobacillus and Bifidobacterium levels, increased Enterobacteriaceae abundance, and a lower Shannon Index (<2). Patients exhibiting both dysbiosis and elevated inflammation had the highest complication rate (60%). Multivariate analysis identified diabetes, elevated IL-6, and dysbiosis as independent predictors of adverse outcomes. (4) Conclusions: Postoperative complications after the modified Whipple procedure are influenced by systemic inflammation and gut dysbiosis. A systematic preoperative assessment of microbiome health and inflammatory markers enables accurate risk stratification and personalized interventions, potentially reducing the incidence of complications and improving overall surgical outcomes.

Surgical site infections (SSIs) following a pancreaticoduodenectomy have been a significant cause of morbidity and even mortality. A modified sequence of the Whipple procedure, using the COMBILAST technique, may reduce SSIs and the patient’s hospital stay. This prospective cohort study included 42 patients undergoing Whipple’s pancreaticoduodenectomy for a periampullary malignancy. The modified sequence pancreaticoduodenectomy technique, COMBILAST, was used to estimate the incidence of SSI and explore other advantages. Of the 42 patients, seven (16.7%) developed superficial SSIs, and two patients (4.8%) had an additional deep SSI. Positive intraoperative bile culture had the strongest association with SSI (OR: 20.25, 95% CI: 2.12, 193.91). The mean operative duration was 391.28 ± 67.86 min, and the mean blood loss was 705 ± 172 mL. A total of fourteen (33.3%) patients had a Clavien–Dindo grade of III or higher. Three (7.1%) patients died of septicemia. The average length of a hospital stay was 13.00 ± 5.92 days. A modified sequence of the Whipple procedure, using the COMBILAST technique, seems promising in reducing SSIs and the patient’s hospital stay. As the approach is only a modification of the operative sequence, it does not compromise the oncological safety of the patient. Moreover, it has an added surgical advantage in reducing the chance of injury to the aberrant or accessory right hepatic artery. Full article
