Background and Objectives: Pancreatoduodenectomy (PD) is the primary treatment for patients with resectable, non-metastatic pancreatic adenocarcinoma and periampullary tumors. Although surgical methods and perioperative management have improved, the procedure still carries a high risk of complications, with postoperative pancreatic fistula (POPF) being the most significant. This study focuses on identifying current risk factors for POPF after PD in a single HPB center. Materials and Methods: We retrospectively analyzed prospectively collected data from patients undergoing PD in our department between October 2018 and April 2024. Data included demographics, comorbidities, lifestyle factors, preoperative tests (bilirubin, CA19-9, HbA1c), intraoperative variables (pancreatic texture, duct diameter), and postoperative outcomes. POPF was classified using the International Study Group of Pancreatic Surgery (ISGPS) criteria. Univariate and multivariate logistic regression analyses were performed. Results: A total of 118 patients underwent PD (82 males, 36 females; mean age 67 (45–85) years; mean body mass index (BMI) 26.6 kg/m²). POPF occurred in 37 patients (31%), with 27 Grade B (23%) and 10 Grade C (9%). The 30- and 90-day mortality rates were 5% and 12.7%, respectively. Univariate analysis showed associations between POPF and soft pancreas (p = 0.018), c-reactive protein (CRP) on postoperative day (POD) 5 (p = 0.004), and serum amylase on POD 0 (p = 0.008). Diabetes mellitus was associated with a lower incidence of POPF (p = 0.014). Multivariate analysis confirmed CRP on POD 5 (OR 1.007, p = 0.025) and DM (OR 0.254, p = 0.015), as independent factors. ROC analysis identified POD 0 amylase >113.5 U/L (AUC 0.717) and POD 5 CRP >125.3 mg/dL (AUC 0.669) as predictive values. Conclusions: POPF remains an important complication after PD. CRP > 126 mg/dL on POD 5 was associated with POPF and may serve as an adjunctive signal to guide further assessment, including imaging. The observed inverse association with diabetes mellitus is hypothesis-generating and should be interpreted cautiously, considering potential confounding and the influence of center volume, surgeon heterogeneity, and institutional protocols.

Background and Objectives: Pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ) are the two most frequently employed reconstruction techniques following pancreaticoduodenectomy (PD), yet the optimal method remains debated. The objective of this study was to compare perioperative outcomes of PG versus PJ in patients undergoing PD for resectable periampullary tumors at a high-volume center. Materials and Methods: We conducted a retrospective cohort study including 604 consecutive patients who underwent PD between January 2019 and May 2025. Reconstruction of the pancreatic remnant was achieved by binding PG in 415 patients and duct-to-mucosa PJ in 189 patients. Demographics, intraoperative data, and postoperative outcomes were analyzed using standardized ISGPS/ISGLS definitions. Results: The overall complication rate was similar between groups (43.9% vs. 47.1%; p = 0.481). However, PG was associated with significantly lower rates of postoperative pancreatic fistula (POPF) (12.3% vs. 18.5%; p = 0.042) and postoperative biliary fistula (POBF) (2.9% vs. 6.3%; p = 0.044) compared with PJ. No significant differences were observed in delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), intra-abdominal abscess, relaparotomy, length of postoperative stay, or 90-day mortality. Conclusions: PG was associated with reduced rates of anastomotic fistulas compared with PJ, while other perioperative outcomes were comparable. These findings suggest that PG may be particularly advantageous in patients with a soft pancreatic remnant or nondilated duct, where the risk of fistula is higher, whereas PJ remains appropriate for firm, fibrotic glands with dilated ducts. Tailoring the reconstructive technique to pancreatic texture and ductal anatomy may therefore improve surgical outcomes and reduce postoperative morbidity. Full article

Background: Hepato-pancreato-biliary (HPB) surgery involves operations that depend heavily on precise imaging, careful planning, and intraoperative decision-making. The rapid emergence of artificial intelligence (AI) and digital tools has assisted in these domains. Methods: We performed a PRISMA-guided systematic review (searches through June 2025) of AI/digital technologies applied to HPB surgical care, including novel models such as machine learning, deep learning, radiomics, augmented/mixed reality, and computer vision. Our focus was for eligible studies to address imaging interpretation, preoperative planning, intraoperative guidance, or outcome prediction. Results: In total, 38 studies met inclusion criteria. Imaging models constructed with AI showed high diagnostic performance for lesion detection and classification (commonly AUC ~0.80–0.98). Moreover, risk models using machine learning frequently exceeded traditional scores for predicting postoperative complications (e.g., pancreatic fistula). AI-assisted three-dimensional visual reconstructions enhanced anatomical understanding for preoperative planning, while augmented and mixed-reality systems enabled real-time intraoperative navigation in pilot series. Computer-vision systems recognized critical intraoperative landmarks (e.g., critical view of safety) and detected hazards such as bleeding in near real time. Most of the studies included were retrospective, single-center, or feasibility designs, with limited external validation. Conclusions: The usage of AI and digital tools show promising results across the HPB pathway—from preoperative diagnostics to intraoperative safety and guidance. The evidence to date supports technical feasibility and suggests clinical benefit, but routine adoption and further conclusions should await prospective, multicenter validation and consistent reporting. With continued refinement, multidisciplinary collaboration, appropriate cost effectiveness, and attention to ethics and implementation, these technologies could improve the precision, safety, and outcomes of HPB surgery.

Background and Objectives: Preoperative biliary drainage (PBD) in patients with periampullary neoplasms remains a debated topic, with various techniques available and conflicting evidence regarding their impact on postoperative outcomes. This study aimed to assess, in a high-volume pancreatic surgery center, whether the choice among endoscopic, surgical, or no preoperative biliary drainage influences postprocedural and postoperative complication rates. Materials and Methods: A retrospective cohort study was conducted at the Surgical Department of the “Octavian Fodor” Regional Institute of Gastroenterology and Hepatology in Cluj-Napoca, Romania, between January 2017 and May 2023. A total of 655 patients undergoing pancreaticoduodenectomy or total pancreatectomy for resectable periampullary tumors were divided into three groups: no PBD, endoscopic PBD, and surgical PBD. Clinical, procedural, and postoperative variables were collected and statistically analyzed. Results: Endoscopic drainage was associated with a significantly higher rate of postoperative intra-abdominal abscesses, postoperative pancreatic fistula (POPF), and pancreaticojejunostomy fistula compared to surgical drainage and no PBD. Patients in the endoscopic group also exhibited significantly higher rates of positive bile cultures, particularly with pluribacterial populations. Procedure-related complications, such as pancreatitis and cholangitis, were significantly lower in the surgical drainage group. No significant differences were found among groups regarding postoperative hospital stay, relaparotomy rates, or 90-day mortality. Conclusions: Surgical biliary drainage was associated with lower perioperative morbidity compared to endoscopic drainage. While endoscopic drainage remains the most commonly used approach, surgical drainage may offer a safer alternative in selected patients. Prospective randomized controlled trials are warranted to validate these findings. Full article

Background/Objectives: Like many other countries, the management of pancreatic cancer in Spain has developed in a fragmented manner. This study analyzes clinical outcomes related to patient volume at different centers after left pancreatectomy (LP). Our goal is to determine whether our practices align with the standards established in the literature and assess whether centralization’s advantages significantly outweigh its disadvantages. Methods: The SPANDISPAN Project (SPANish DIStal PANcreatectomy) is an observational, prospective, multicenter study focused on LP conducted in Spanish Hepato-Pancreato-Biliary (HPB) Surgery Units from 1 February 2022 to 31 January 2023. HPB units were defined as high volume if they performed more than 10 LPs annually. Results: This study included 313 patients who underwent LP at 42 centers across Spain over the course of a year. A total of 40.3% of the procedures were performed in high-volume centers. Significant differences in preoperative variables were only observed in ASA scores, which were higher in the high-volume group. Intraoperatively, minimally invasive surgical techniques were performed more frequently in high-volume centers. Postoperatively, the administration of somatostatin, major complications, and B and C postoperative pancreatic fistula (POPF) were more frequent in low-volume hospitals. Conclusions: The findings revealed that high-volume centers had a higher rate of minimally invasive surgery, lower intraoperative bleeding, fewer complications, and reduced POPFs compared to low-volume centers. However, it is important to note that low-volume centers still demonstrated acceptable outcomes. Thus, the selective referral of more complex laparoscopic procedures could initiate a gradual centralization of surgical practices. Full article

Background: Gallstone ileus is a rare cause of bowel obstruction, often presenting with nonspecific symptoms that delay diagnosis. This study assessed the diagnostic value of CT imaging and its correlation with histopathological findings in confirmed cases. Methods: A retrospective analysis of 14 patients with surgically confirmed gallstone ileus was performed. All underwent abdominal radiography, ultrasound, and CT. Imaging findings were evaluated for calcification type, impaction site, and fistula presence. Histopathology from surgical specimens was used for correlation. Relative risk (RR) and 95% confidence intervals (CIs) were calculated, with adjustments for small sample size. Results: Rim-calcified gallstones were the most common (50%) and significantly associated with chronic inflammation (RR 1.42, 95% CI: 1.05–1.93). Cholecystoduodenal fistulas were most frequent (57.1%), with a 92.8% imaging-pathology concordance. Ileal impaction (35.7%) was linked to increased risk of bowel necrosis (RR 2.0, 95% CI: 1.1–3.6). All stones were >3 cm; two patients had recurrence. No perioperative mortality occurred. Conclusions: CT imaging demonstrates high diagnostic accuracy and strong correlation with histopathological findings in gallstone ileus. Identifying calcification patterns and impaction sites aids early diagnosis and surgical planning. Full article

Patients with Roux-en-Y gastric bypass (RYGB) are a significant challenge for endoscopic retrograde cholangiopancreatography (ERCP) due to the altered anatomy. Endoscopic ultrasound (EUS)-directed transgastric ERCP (EDGE) has emerged as a valuable alternative to standard methods like enteroscopy-assisted (EA-ERCP) and laparoscopy-assisted (LA-ERCP) ERCP. EDGE involves creating a temporary fistula between the gastric pouch and the excluded stomach under EUS guidance, typically using a lumen-apposing metal stent (LAMS). This allows a standard ERCP scope to access the second duodenum and the biliary tree with standard devices. Several studies have investigated the efficacy and safety of this approach, with variations in techniques such as suturing the LAMS to prevent migration. EDGE has demonstrated high technical success rates, and current evidence indicates that it can be performed safely, with acceptable rates of adverse events such as stent migration, bleeding, and perforation, making it the preferred option in referral centers. This comprehensive review aims to provide a concise evaluation of EDGE, its techniques, outcomes, and role in managing biliary and pancreatic disorders in RYGB patients. Full article

This case report describes the acute and multidisciplinary management anesthesiologists performed for an intra-operative bronchobiliary fistula during a routine endoscopic retrograde cholangiopancreatography for a patient with intrahepatic cholangiocarcinoma. During the procedure, an unexpected rapid airway deterioration was encountered due to bile infiltration of the right bronchus and anesthesia circuit, necessitating (1) emergent extubation and reintubation with bronchoscopy, (2) extubation and reintubation with double-lumen endotracheal tube with right-bronchial blocker, and (3) transportation of the patient from endoscopy to interventional radiology for biliary drain placement. Overall, this case highlights a rare but serious consideration for patients with intrahepatic cholangiocarcinoma who may present with a bronchobiliary fistula and the steps taken to prevent total airway compromise and ensure rapid patient stabilization through coordination with advanced gastroenterology, interventional pulmonology, and interventional radiology.

Background and Objectives: The aim of this study was to compare percutaneous aspiration injection reaspiration (PAIR), open surgery (OS), and laparoscopic surgery (LS) in the treatment of liver hydatid cysts in terms of effectiveness, complications, and recurrence rates. Materials and Methods: This retrospective cross-sectional study included 383 patients who were treated with a diagnosis of liver hydatid cyst at Harran University Faculty of Medicine between May 2014 and May 2024. Patients were divided into three groups based on the treatment method: PAIR, OS, and LS. The groups were analyzed in terms of demographic and clinical characteristics such as age, sex, number of cysts, cyst location, and cyst diameter. Various factors such as complications, recurrence rates, and biliary fistula development were compared. Statistical analyses were performed using Jamovi and JASP software, and p ≤ 0.05 was considered significant. Results: The risk of biliary fistula development was found to be significantly lower in patients treated using PAIR than in those in the surgical groups (p < 0.001). While the recurrence rate was higher in the PAIR group, the recurrence rates were similar in the OS and LS groups (p = 0.043). The risk of biliary fistula development and catheter removal time were found to be higher in patients with large cysts (p < 0.001). A strong and statistically significant correlation was observed between the length of hospital stay and the duration until catheter removal (p < 0.001). The maximum diameter of the cyst demonstrated a significant positive correlation with both the length of hospital stay (r = 0.363, p < 0.001) and the duration until catheter removal (p < 0.001). Conclusions: This study demonstrates that the PAIR method is effective in reducing biliary fistula development, but the recurrence rates are higher than OS and LS. OS and LS show similar outcomes in terms of recurrence. Full article

Radiological assessment following pancreaticoduodenectomy is critical for the prompt diagnosis and management of postoperative complications, significantly influencing patient outcomes. Pancreaticoduodenectomy, or the Whipple procedure, is the standard surgical intervention for pancreatic and periampullary malignancies, but it involves notable risks, especially from complications like fistulas, bleeding, or leakage. Cross-sectional imaging, particularly contrast-enhanced computed tomography, serves as the primary diagnostic tool due to its rapid acquisition, high resolution, and effective delineation of postoperative anatomy and complications. Magnetic resonance imaging (with cholangiopancreatography and hepatobiliary contrast agents) complements CT by providing superior contrast resolution for specific complications, notably in the biliary system and pancreatic duct. This narrative review discusses various imaging techniques and their applications, highlighting characteristic radiological features of common postoperative complications. It underscores the importance of a multidisciplinary approach, emphasizing close collaboration between radiologists and surgeons to optimize surgical decision-making and improve patient management post-pancreatic surgery.

Background and Objectives: Cystic echinococcosis (CE) remains a significant health concern in endemic areas, including Romania, where hepatic hydatid cysts frequently require surgical treatment. Surgery represents the cornerstone of therapy, particularly in large, complicated, or symptomatic cysts, where medical or minimally invasive options may be insufficient. This study aims to investigate the clinical characteristics, risk factors, and postoperative evolution of patients undergoing surgical intervention for hepatic CE in a tertiary care center over a five-year period. Materials and Methods: This retrospective study examined data from 62 patients who underwent surgical procedures for hepatic CE during a 5-year period. The analysis focused on demographic parameters, cyst morphology, surgical techniques employed, and postoperative complications, with particular attention to the frequency, management, and outcomes of biliary fistulas. Results: The study cohort had an average age of 44.1 years, with a slight predominance of female patients (51.6%). The majority of cysts (62.9%) were located in the right hepatic lobe, with an average diameter of 10.9 cm. Postoperative complications were recorded in 25.8% of cases, with biliary fistulas being the most frequent (12.9%). Patients who developed biliary fistulas presented significantly larger cysts (152.13 ± 105.68 mm vs. 102.20 ± 37.86 mm, p = 0.012) and required an extended length of hospitalization, particularly in high-output cases (29 vs. 9.3 days, p = 0.045). Hospital stays and treatment expenses were notably higher among patients with biliary fistulas. Conclusions: Biliary fistulas were observed exclusively in patients who underwent partial cystectomy. This finding highlights the need for increased caution when performing partial cystectomy, especially in cases involving large or recurrent cysts, where the risk of postoperative biliary fistulas is higher. Tailoring the surgical technique based on cyst characteristics and incorporating intraoperative strategies to manage or prevent biliary leakage may help reduce morbidity. Early identification and multidisciplinary management of high-risk cases are key to improving outcomes in hepatic CE. Full article

Background: A 69-year-old man with multiple myeloma and left-sided heart failure presented to the hospital with a two-month fever. Method: A transjugular liver biopsy was performed due to the rapid progression of liver failure. The procedure was complicated by an intraperitoneal hemorrhage. The bleeding was managed expectantly. Result: Significantly elevated serum bilirubin levels occurred on the 13th day after liver biopsy. Increasing serum bilirubin levels were observed until the patient’s death due to a biliovenous fistula at the liver biopsy site. Simultaneously, his slightly elevated liver enzymes returned to normal. The patient died 23 days after liver biopsy due to acute respiratory distress syndrome. Fistulous communication between the biliary tree and the hepatic venous system with subsequent bile leakage into the venous system (bilhemia) can lead to bile deposition in the lungs. Bile deposition in the lungs may potentiate and accelerate the development of diffuse alveolar damage with hyaline membranes. Conclusions: Lambda and kappa light chain deposition in the pulmonary alveoli in patients with multiple myeloma can mimic typical hyaline membranes. Full article

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. Full article

Background: Liver transplantation constitutes a well-established treatment for patients with end-stage liver disease and selected hepatic malignancies. The introduction of normothermic machine perfusion (NMP) offers a platform for both extracorporeal organ maintenance and viability assessment, especially for organs with suspicious malfunction. These organs, discarded by the majority of transplant centers (so-called ‘orphan livers’), may help to safely expand the donor pool thanks to pre-transplant appraisal; Methods: We identified all grafts undergoing normothermic ma-chine perfusions performed in the Department of General, Transplant, and Liver Surgery between December 2022 and August 2023. Their perfusion characteristics and immediate postoperative periods, as well as complications that occurred in the 90-day postoperative periods, were analyzed; Results: There were eight orphan liver grafts that underwent NMP in our Department. Postoperative complications occurring in patients receiving grafts after NMP did not seem associated with the procedure. One patient required laparotomy within the 90-day postoperative period due to biliary fistula and underwent bile duct stenting due to both fistula and nonanastomotic stricture. In one patient we observed the occurrence of anastomotic biliary stricture more than 90 days after LTx; Conclusions: NMP allows for the viability assessment of grafts with suspicious prepreservation malfunction. Some of these organs may help to expand the donor pool. Full article

Introduction: Bouveret syndrome, a rare and often underdiagnosed variant of gallstone ileus, is characterized by the presence of a large gallstone impacted in the proximal duodenum, resulting in significant gastric outlet obstruction and aerobilia. Early identification of Bouveret syndrome is crucial for developing an appropriate surgical strategy. Case 1: A 76-year-old female underwent a contrast-enhanced abdominal CT scan, which revealed a cholecysto-duodenal fistula with a 3.9 cm × 4.0 cm × 4.0 cm gallstone located in the proximal duodenum, along with a distended, fluid-filled stomach and aerobilia. Intraoperatively, due to chronic inflammation and adhesion between the gallbladder and duodenum, a cholecystectomy and fistula repair were performed. Case 2: A 72-year-old female presented with a gastroduodenal passage obstruction confirmed by imaging, which identified a duodeno-biliary fistula. The radiological examination showed oval filling defects in the duodenal bulb consistent with Bouveret’s syndrome, with the largest stone measuring approximately 6 cm in diameter. An enterotomy was performed for stone extraction and was followed by cholecystectomy and duodenal repair with omentoplasty. Conclusions: Bouveret’s syndrome is a rare but clinically significant condition that should be considered in patients presenting with signs of upper gastrointestinal obstruction, particularly in those with a history of chronic cholelithiasis. Early recognition and prompt surgical intervention are essential for obtaining optimal patient outcomes. Full article
