Associations of body composition parameters with postoperative outcome and perineural tumour invasion after oncological pancreatic resection. BMC Surg 2024; 24:175.

Abstract
BACKGROUND Pancreatic cancer is often accompanied by wasting conditions. While surgery is the primary curative approach, it poses a substantial risk of postoperative complications, hindering subsequent treatments. Therefore, identifying patients at high risk for complications and optimizing their perioperative general condition is crucial. Sarcopenia and other body composition abnormalities have shown to adversely affect surgical and oncological outcomes in various cancer patients. As most pancreatic tumours are located close to the neuronal control centre for the digestive tract, it is possible that neural infiltration in this area deranges bowel functions and contributes to malabsorption and malnutrition and ultimately worsen sarcopenia and weight loss. METHODS A retrospective analysis of CT scans was performed for pancreatic cancer patients who underwent surgical tumour resection at a single high-volume centre from 2007 to 2023. Sarcopenia prevalence was assessed by skeletal muscle index (SMI), and visceral obesity was determined by the visceral adipose tissue area (VAT). Obesity and malnutrition were determined by the GLIM criteria. Sarcopenic obesity was defined as simultaneous sarcopenia and obesity. Postoperative complications, mortality and perineural tumour invasion, were compared among patients with body composition abnormalities. RESULTS Of 437 patients studied, 46% were female, the median age was 69 (61;74) years. CT analysis revealed 54.9% of patients with sarcopenia, 23.7% with sarcopenic obesity and 45.9% with visceral obesity. Sarcopenia and sarcopenic obesity were more prevalent in elderly and male patients. Postoperative surgical complications occurred in 67.7% of patients, most of which were mild (41.6%). Severe complications occurred in 22.7% of cases and the mortality rate was 3.4%. Severe postoperative complications were significantly more common in patients with sarcopenia or sarcopenic obesity. Visceral obesity or malnutrition based on BMI alone, did not significantly impact complications. Perineural invasion was found in 80.1% of patients and was unrelated to malnutrition or body composition parameters. CONCLUSIONS This is the first and largest study evaluating the associations of CT-based body mass analysis with surgical outcome and histopathological perineural tumour invasion in pancreatic cancer patients. The results suggest that elderly and male patients are at high risk for sarcopenia and should be routinely evaluated by CT before undergoing pancreatic surgery, irrespective of their BMI. Confirmation of the results in prospective studies is needed to assess if pancreatic cancer patients with radiographic sarcopenia benefit from preoperative amelioration of muscle mass and function by exercise and nutritional interventions.

Abstract
Pancreatic cancer is the most common medical condition that requires pancreatic resection. Over the last three decades, significant improvements have been made in the conditions and procedures related to pancreatic surgery, resulting in mortality rates lower than 5%. However, it is important to note that the morbidity in pancreatic surgery remains r latively high, with a percentage range of 30-60%. Pre-operative malnutrition is considered to be an independent risk factor for post-operative complications in pancreatic surgery, such as impaired wound healing, higher infection rates, prolonged hospital stay, hospital readmission, poor prognosis, and increased morbidity and mortality. Regarding the post-operative period, it is crucial to provide the best possible management of gastrointestinal dysfunction and to handle the consequences of alterations in food digestion and nutrient absorption for those undergoing pancreatic surgery. The European Society for Clinical Nutrition and Metabolism (ESPEN) suggests that early oral feeding should be the preferred way to initiate nourishing surgical patients as it is associated with lower rates of complications. However, there is ongoing debate about the optimal post-operative feeding approach. Several studies have shown that enteral nutrition is associated with a shorter time to recovery, superior clinical outcomes and biomarkers. On the other hand, recent data suggest that nutritional goals are better achieved with parenteral feeding, either exclusively or as a supplement. The current review highlights recommendations from existing evidence, including nutritional screening and assessment and pre/post-operative nutrition support fundamentals to improve patient outcomes. Key areas for improvement and opportunities to enhance guideline implementation are also highlighted.

High hand grip strength is a significant risk factor and a useful predictor of postoperative pancreatic fistula following pancreaticoduodenectomy. Langenbecks Arch Surg 2024; 409:85. [PMID: 38438660 DOI: 10.1007/s00423-024-03274-3] [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: 01/02/2024] [Accepted: 02/27/2024] [Indexed: 03/06/2024]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is one of the most critical complications of pancreaticoduodenectomy (PD). Studies on predictive factors for POPF that can be identified preoperatively are limited. Recent reports have highlighted the association between the preoperative nutritional status, including sarcopenia, and postoperative complications. We examined preoperative risk factors for POPF after PD, focusing on nutritional indicators. METHODS A total of 153 consecutive patients who underwent PD at our institution were enrolled in this study. Preoperative nutritional parameters, including hand grip strength (HGS) and skeletal muscle mass as components of sarcopenia, were incorporated into the analysis. POPFs were categorized according to the International Study Group of Pancreatic Fistula (ISGPF) definition as biochemical (grade A) or clinically relevant (CR-POPF; grades B and C). RESULTS Thirty-seven of the 153 patients (24.1%) fulfilled the ISGPF definition of CR-POPF postoperatively. In the univariate analysis, the incidence of CR-POPF was associated with male sex, non-pancreatic tumor diseases, a high body mass index, a high HGS and a high skeletal muscle mass index. In the multivariate analysis, non-pancreatic tumor diseases and an HGS ≥23.0 kg were selected as independent risk factors for CR-POPF (P <0.05). CONCLUSIONS A high HGS, a screening tool for sarcopenia, was a risk factor for CR-POPF. It can accurately serve as a useful predictor of POPF risk in patients undergoing PD. These results highlight the potential of sarcopenia to reduce the incidence of POPF and highlight the need to clarify the mechanism of POPF occurrence.

Abstract
Background Postoperative pancreatic fistula (POPF) is a perilous complication that may arise subsequent to pancreaticoduodenectomy (PD). In recent times, there has been an escalating interest in employing machine learning (ML) techniques to aid in treatment decision-making. The purpose of this research is to assess the effectiveness of ML in comparison to conventional models, while also conducting an initial evaluation of the predictive capability of skeletal muscle index (SMI) concerning POPF. Methods This retrospective observational study was carried out at The First Affiliated Hospital of Wenzhou Medical University from January 2012 to January 2021, encompassing data from 269 patients who underwent PD. After identifying independent factors associated with the condition, a logistic regression model was employed to construct a nomogram, alongside the establishment of five ML models. To assess their effectiveness, the best-performing ML model and nomogram were evaluated on a separate test group comprising 77 additional patients. The evaluation involved comparing the area under the curve (AUC) and Brier score. Results Among the 269 patients studied, the incidence of POPF was found to be 56.9%, with 106 patients (69.3%) experiencing clinically-relevant POPF. We identified six independent factors associated with POPF, including body mass index (BMI), SMI, pancreatic duct dilatation, tumor size, triglyceride levels, and the ratio of aspartate aminotransferase to alanine aminotransferase (AST/ALT) on the first postoperative day. When evaluated on the test set, the Gaussian Naive Bayes (GNB) model, which was the best-performing ML model, achieved an AUC of 0.824 and a Brier score of 0.175. The corresponding performance indicators for the nomogram were 0.844 for AUC and 0.165 for the Brier score. Conclusions This study found that there is minimal difference between ML and the nomogram based on logistic regression in predicting POPF. Additionally, SMI shows promise as a potential and practical tool for assessing the risk of POPF.

Abstract
Approximately 15%-19% of patients with severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infections develop gastrointestinal symptoms. Acute pancreatitis (AP) has been reported in 0.1% of patients with coronavirus disease 2019 (COVID-19). Biliary AP was most common (78.4%) before the COVID-19 pandemic; idiopathic AP is most common in patients with COVID-19 (up to 57.1%). The number of emergency department presentations decreased by 23.3% during the pandemic and many governments made national recommendations to delay nonurgent endoscopic procedures, leading to decrements of 22% in combined esophagogastroduodenoscopy (EGD) and colonoscopy and 20% in EGD after the COVID-19 pandemic. The symptoms and signs of COVID-19-related AP are fever (63%), abdominal pain (58%), respiratory symptoms (40%), nausea and vomiting (39%), and headache (4%). Approximately 5-10% of patients develop necrotizing or hemorrhagic AP, and patients who required surgical intervention had a higher mortality risk. Compared to 2019, the rates of elective surgery decreased by 41.8% in 2020; including cholecystectomy (40.1% decrease) and pancreas (111.1% decrease). Surgical volumes also decreased by 18.7% in 2020; device-assisted laparoscopic and robot-assisted procedures reduced by 45.4% and 61.9% during the COVID-19 Lockdown in 2020.
