Analysis of factors influencing pancreatic fistula after minimally invasive pancreaticoduodenectomy and establishment of a new prediction model for clinically relevant pancreatic fistula. Surg Endosc 2024; 38:2622-2631. [PMID: 38499780 PMCID: PMC11078842 DOI: 10.1007/s00464-024-10770-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 02/22/2024] [Indexed: 03/20/2024]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is the most prevalent complications following minimally invasive pancreaticoduodenectomy (MIPD). Only one model related to MIPD exists, and previous POPF scoring prediction methods are based on open pancreaticoduodenectomy patients. Our objectives are to determine the variables that may increase the probability of pancreatic fistula following MIPD and to develop and validate a POPF predictive risk model. METHODS Data from 432 patients who underwent MIPD between July 2015 and May 2022 were retrospectively collected. A nomogram prediction model was created using multivariate logistic regression analysis to evaluate independent factors for POPF in patients undergoing MIPD in the modeling cohort. The area under the curve (AUC) of the receiver operating characteristic curve (ROC) and the calibration curve were used to verify the nomogram prediction model internally and externally within the modeling cohort and the verification cohort. RESULTS Multivariate logistic regression analysis showed that body mass index (BMI), albumin, triglycerides, pancreatic duct diameter, pathological diagnosis and intraoperative bleeding were independent variables for POPF. On the basis of this information, a model for the prediction of risks associated with POPF was developed. In accordance with the ROC analysis, the modeling cohort's AUC was 0.819 (95% CI 0.747-0.891), the internal validation cohort's AUC was 0.830 (95% CI 0.747-0.912), and the external validation cohort's AUC was 0.793 (95% CI 0.671-0.915). Based on the calibration curve, the estimated values of POPF have a high degree of concordance with the actual values that were measured. CONCLUSIONS This model for predicting the probability of pancreatic fistula following MIPD has strong predictive capacity and can provide a trustworthy predictive method for the early screening of high-risk patients with pancreatic fistula after MIPD and timely clinical intervention.

Abstract
BACKGROUND Post-operative pancreatic fistula (POPF) is a major complication following pancreatectomy and is currently difficult to predict pre-operatively. This study aims to validate pre-operative risk factors and develop a novel combined score for the prediction of POPF in the pre-operative setting. METHODS Data were collected from 2016 to 2021 for radiologic main pancreatic duct diameter (MPD), body mass index (BMI), physical status classified by American Society of Anesthesiologists (ASA), polypharmacy, mean platelet ratio (MPR), comorbidity-polypharmacy score (CPS), and a novel Combined Pancreatic Leak Prediction Score (CPLPS) (derived from MPD diameter, BMI, and CPS) were obtained from pre-operative data and analyzed for their independent association with POPF occurrence. RESULTS In total, 166 patients who underwent pancreatectomy with pancreatic leak (Grade A, B, and C) occurring in 51(30.7%) of patients. Pre-operative radiologic MPD diameter < 4 mm (p < 0.001), < 5 mm (p < 0.001), < 6 mm (p = 0.001), BMI ≥ 25 (p = 0.009), and ≥ 30 (p = 0.017) were independently associated with the occurrence of pancreatic leak. CPLPS was also predictive of pancreatic leak following pancreatectomy on univariate (p = 0.005) and multivariate analysis (p = 0.036). CONCLUSION MPD and BMI were independent risk factors predictive for the development of pancreatic leak. CPLPS, was an independent predictor of pancreatic leak following pancreatectomy and could be used to help guide surgical decision making and patient counseling.

Abstract
BACKGROUND The TRIANGLE operation benefits patients with pancreatic cancer; however, the Heidelberg triangle, where the operation occurs, contains vessels that can impact safety, especially in laparoscopic pancreaticoduodenectomy (LPD) with the TRIANGLE operation. This study aimed to identify Heidelberg triangle vessel types and their implications in pancreaticoduodenectomy (PD). METHODS Retrospective collection of radiographic data was performed from January 2017 to April 2023. Three-dimensional (3D) CT reconstructions were performed on patients. Vascular types in the Heidelberg triangle were classified based on named vessels crossing its interior. The impact of these types on surgical outcomes and complications in PD with the TRIANGLE operation was assessed. RESULTS Preoperative CT reconstruction was conducted on 184 pancreatic surgery patients. The findings revealed 99 patients (53.8%) with the type I Heidelberg triangle, lacking named vessels crossing the interior. Type II (n = 85, 46.2%), with named vessels crossing the interior, was identified. Among reconstructed patients who underwent PD with the TRIANGLE operation (n = 103), they were categorized as type I (n = 57) or type II (n = 46). The results showed that LPD patients with type II had significantly higher median intraoperative blood loss (300 mL vs. 200 mL, P = 0.030) and mean examined lymph nodes (17.2 ± 7.6 vs. 13.4 ± 5.2, P = 0.019) compared to those with type I. No significant differences were found in operative time or postoperative complications. CONCLUSION The presence of named vessels crossing the interior of the Heidelberg triangle was associated with increased intraoperative bleeding during LPD combined with the TRIANGLE operation. Therefore, targeted preoperative planning is required before the operation, thus improving the safety of the TRIANGLE operation in minimally invasive surgery.

Abstract
Pancreatic fistulas are highly feared complications following surgery on or near the pancreas, abdominal trauma, or severe inflammation. These fistulas arise from leaks in the pancreatic ductal system, leading to various complications such as abscesses, delayed gastric emptying, and hemorrhage. Severe cases present with sepsis or organ failure, dramatically increasing mortality and morbidity. Risk factors include smoking, high BMI, male gender, age, and surgery-related factors like prolonged operation time and non-ligation of the main pancreatic duct. Therefore, treatment options and preventive measurements have become a hot topic in recent years. Studies have investigated the use of fibrin sealants, different closure methods, and less invasive surgical techniques. Treatment options consist of conservative measurements and the use of percutaneous drainage, prophylactic transpapillary stenting, and surgery in severe cases. As EUS has become widely available, transmural stenting started to influence the management of pancreatic fluid collections (PFCs). However, studies on its use for the management of pancreatic fistulas are lacking. Medical treatment options like somatostatin analogs and pasireotide have been investigated but yielded mixed results.

Abstract
BACKGROUND AND OBJECTIVE Postoperative pancreatic fistula (POPF) is the leading cause of morbidity and early mortality in patients undergoing pancreatic resection. In addition, recent studies have identified postoperative acute pancreatitis (POAP) as an independent contributor to morbidity. Most perioperative mitigation strategies experimented for POPF have been shown to be in vain with no consensus on the best perioperative management. Clinical prediction models have been developed with the hope of identifying high POPF risk patients with the leading idea of finding subpopulations possibly benefiting from pre-existing or novel mitigation strategies. The aim of this review was to map out the existing prediction modeling studies to better understand the current stage of POPF prediction modeling, and the methodology behind them. METHODS A narrative review of the existing POPF prediction model studies was performed. Studies published before September 2022 were included. RESULTS While the number of POPF prediction models for pancreatoduodenectomy has increased, none of the currently existing models stand out from the crowd. For distal pancreatectomy, two unique POPF prediction models exist, but due to their freshness, no further external validation or adoption in clinics or research has been reported. There seems to be a lack of adherence to correct methodology or reporting guidelines in most of the studies, which has rendered external validity-if assessed-low. Few of the most recent studies have demonstrated preoperative assessment of pancreatic aspects from computed tomography (CT) scans to provide relatively strong predictors of POPF. CONCLUSIONS Main goal for the future would be to reach a consensus on the most important POPF predictors and prediction model. At their current state, few models have demonstrated adequate transportability and generalizability to be up to the task. Better understanding of POPF pathophysiology and the possible driving force of acute inflammation and POAP might be required before such a prediction model can be accessed.

Abstract
OBJECTIVE To provide an overview of the current practice of intraoperative blood loss (BL) estimation in hepato-pancreato-biliary (HPB) surgery. BACKGROUND Intraoperative BL is a major quality marker in HPB surgery and a predictor of perioperative outcomes. However, the method for BL estimation is not standardized. METHODS A systematic review was performed of original studies published between 2006 and 2021 reporting the intraoperative BL of patients undergoing pancreatic or hepatic resections. A web-based snapshot survey was distributed globally to all members of the International Hepato-Pancreato-Biliary Association (IHPBA). RESULTS A total of 806 studies were included; 480 (60%) had BL as their primary outcome, and 105 (13%) had BL as their secondary outcome. However, 669 (83%) did not specify how BL estimation was performed, and 9 different methods were found among the remaining 136 (17%) studies.The survey was completed by 252 surgeons. Most of the responders (94%) declared that they systematically performed BL estimation and considered BL predictive of postoperative complications after pancreatic (73%) and liver (74%) resection. All methods previously identified in the literature were used by responders with different frequencies. A calculation based on suction fluid amounts, operative gauze weight, and irrigation was the most used method in the literature (7%) and among responders (51%). Most responders (83%) felt that BL estimation in HPB surgery needs improved standardization. CONCLUSIONS Standardization of intraoperative BL estimation is urgently needed in HPB surgery to ensure the consistency of reporting and reproducibility.

Abstract
Background: To investigate changes over the last decades in the management of postoperative complications following pancreatoduodenectomy (PD) with special emphasis on reoperations, their indications, and outcomes. Methods: 409 patients who underwent PD between 2008 and 2021 were retrospectively analyzed with respect to their need for reoperations (reoperation, n = 81, 19.8% vs. no reoperation, n = 328, 80.2%). The cohort was then compared to a second cohort comprising patients who underwent PD between 1989 and 2007 (n = 285). Results: 81 patients (19.8%) underwent reoperation. The main cause of reoperation was the dehiscence of pancreatogastrostomy (22.2%). Reoperation was associated with a longer duration of the index operation, more blood loss, and more erythrocyte concentrates being transfused. Patients who underwent reoperation showed more postoperative complications and a higher mortality rate (25% vs. 2%, p < 0.001). Compared to the earlier cohort, the observed increase in reoperations did not lead to increased mortality (5% vs. 6%, p = 353). Conclusions: The main cause for reoperation has changed over the last decades and was the dehiscence of pancreatogastrostomy. Associated with a leakage of pancreatic fluid and clinically relevant PF, it remains the most devastating complication following PD. Strategies for prevention and treatment, e.g., by endoscopic vacuum-assisted-closure therapy are of utmost importance.
