Background and Objectives: Preoperative biliary stenting (PBS) is commonly used to manage obstructive jaundice in patients undergoing pylorus-preserving pancreaticoduodenectomy (PPPD). However, the impact of PBS on intestinal barrier function and perioperative complications remains controversial. This study aims to evaluate the effect of PBS on intestinal dysfunction and surgical outcomes, focusing on the influence of the stent duration. Materials and Methods: In this prospective cohort study, 235 patients undergoing PPPD for resectable pancreatic neoplasms at Timișoara Municipal Emergency Clinical Hospital (2016–2024) were analyzed. Patients were divided into two groups: those with PBS (n = 98) and without PBS (n = 137). Intestinal barrier function was assessed pre- and postoperatively using biomarkers such as zonulin, fecal calprotectin, and serum lipopolysaccharides (LPS). Perioperative outcomes, including pancreatic fistula, delayed gastric emptying (DGE), infections, and hospital stay, were compared. Additionally, outcomes were stratified based on stent duration (2–3 weeks vs. 3–4 weeks). Results: PBS was associated with significantly higher levels of zonulin, fecal calprotectin, and serum LPS postoperatively, indicating compromised intestinal barrier function. The stented group had a higher incidence of pancreatic fistulas (Grade B/C: 27.5% vs. 13.1%, p < 0.01), DGE (25.5% vs. 13.1%, p = 0.008), postoperative infections (34.7% vs. 17.5%, p = 0.002), and prolonged hospital stay (16.9 ± 4.2 days vs. 14.5 ± 3.7 days, p = 0.019). Prolonged stenting (3–4 weeks) was associated with worse outcomes compared to shorter stenting durations (2–3 weeks), including increased rates of infections, sepsis, and ICU stay (p < 0.05 for all comparisons). Conclusions: Preoperative biliary stenting is associated with increased intestinal barrier dysfunction, systemic inflammation, and higher rates of perioperative complications following PPPD. Prolonged stenting durations (>3 weeks) further exacerbate these risks. Limiting the PBS duration to 2–3 weeks, alongside optimized perioperative management, may help reduce postoperative morbidity and improve surgical outcomes.

Background: Pancreatic ductal adenocarcinoma is an aggressive neoplasm with a complex carcinogenesis process that must be understood through the interactions between tumor cells and tumor microenvironment cells. Methods: This study was retrospective with a chronological extension period of 16 years and included 56 cases of pancreatic ductal adenocarcinoma. This study identified, quantified, and correlated the cells of the tumor immune microenvironment in pancreatic ductal adenocarcinoma with major prognostic factors as well as overall survival, using an extensive panel of immunohistochemical markers. Results: Three tumor immunotypes were identified: subtype A (hot immunotype), subtype B (intermediate immunotype), and subtype C (cold immunotype). Patients with immunotype C exhibit considerably higher rates of both pancreatic fistulas and acute pancreatitis. Immunotypes B and C significantly increased the risk of this complication by factors of 3.68 (p = 0.002) and 3.94 (p = 0.001), respectively. The estimated probabilities of fistula formation for each immunotype are as follows: 2.5% for immunotype A, 25% for immunotype B, and 28% for immunotype C. There was a statistically significant difference in median survival times according to tumor immunotype (p < 0.001). Specifically, patients with immunotype C tumors had a median survival time of only 120.5 days, compared to 553.5 days for those with immunotype A and 331.5 for immunotype B tumors. Conclusions: The identification of the immunotype of pancreatic ductal adenocarcinoma can be a predictive factor for the occurrence of complications such as pancreatic fistula as well as for overall survival.

Background and objectives: Immune thrombocytopenic purpura (ITP) is a rare hematological disorder characterized by an autoimmune-mediated decline in platelet count in peripheral blood. Over the years, its treatment has evolved, leading to a decline in the role of splenectomy, which was previously used as a second-line therapy. This study aims to evaluate the effects of spleen removal on the progression of the disease, regardless of the surgical procedure, by presenting a single-center experience. Materials and Methods: We retrospectively reviewed the medical records of all ITP patients who underwent splenectomy and were admitted to the Hematology Clinic of Timișoara Emergency City Hospital between January 1988 and June 2024. A total of 217 ITP patients who underwent splenectomy were identified over a 37-year period. Demographic data, postoperative complications, and responses to splenectomy were analyzed over a median follow-up period of 93.86 ± 104.25 months, ranging from 6 to 423 months. Results: Among the 217 patients included in the study, 155 (71.42%) were female and 62 (28.58%) were male, with a mean age of 38.47 ± 16.12 years. During the follow-up period, a significant decrease in the number of splenectomies was observed (p < 0.001). The overall morbidity rate was 14.28%. The overall response rate after splenectomy was 85.71%, with 158 patients (72.81%) achieving a complete response and 28 (12.90%) achieving a partial response. However, 28 (15.05%) of the responsive patients experienced relapse during follow-up and required additional medical therapy. Analyzing the association between comorbidities and relapse after splenectomy, the presence of diabetes (OR = 6.90, 95% CI: 2.87–16.58), hepatic diseases (OR = 64.60, 95% CI: 19.60–212.91), immune thyroid disorders (OR = 8.37, 95% CI: 2.09–33.46), and obesity (OR = 10.22, 95% CI: 3.41–30.60) were identified as risk factors for relapse using univariate analysis. Conclusions: Splenectomy remains the treatment with the best long-term outcomes compared to other therapies. However, concerns about early and late complications following splenectomy, along with advancements in modern ITP treatments, have led to a significant decline in the number of splenectomies performed. In univariate analyses, female gender, age over 40, and the presence of diabetes, hepatic diseases, obesity, or immune thyroid disorders were found to be risk factors for relapse following splenectomy. In the logistic regression analysis adjusted for age and sex, obesity and steatosis were significantly associated with an increased risk of relapse after splenectomy in women over 40 years of age.

(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.

Groove pancreatitis represents a chronic focal form of pancreatitis affecting the zone between the pancreatic head and the duodenal “C” loop, known as the groove area. This is a rare condition that affects the pancreatic periampullary part, including the duodenum and the common bile duct, which is usually associated with long-term alcohol and tobacco misuse, and is more frequent in men than in women. The most common clinical symptoms of groove pancreatitis include weight loss, acute abdominal pain, nausea, and jaundice. This report is about a 66-year-old woman with a history of heavy smoking, presenting with weight loss, nausea, and upper abdominal pain. Contrast-enhanced computed tomography revealed the existence of chronic pancreatitis as well as the dilatation of the main pancreatic duct, a cyst of the pancreatic head, and enlargement of the biliary tract. Conservatory treatment was initiated but with no improvement of symptoms. Since endoscopic retrograde cholangiopancreatography was not possible due to the local changes, we decided to perform pancreatoduodenectomy, as surgery appears to be the single effective treatment.
