Are transmembrane 6 superfamily member 2 gene polymorphisms associated with steatohepatitis after pancreaticoduodenectomy? JGH Open 2024; 8:e13113. [PMID: 38919271 PMCID: PMC11197035 DOI: 10.1002/jgh3.13113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 05/29/2024] [Accepted: 06/09/2024] [Indexed: 06/27/2024]
Abstract
Aim After pancreaticoduodenectomy, 20-40% of patients develop steatotic liver disease (SLD), and steatohepatitis can be a problem. Although patatin-like phospholipase domain-containing 3 protein (PNPLA3) and transmembrane 6 superfamily member 2 (TM6SF2) polymorphisms are involved in SLD and steatohepatitis development, whether this is the case after pancreaticoduodenectomy is unclear. Methods and Results Forty-three patients with pancreatic cancer who underwent pancreaticoduodenectomy at our hospital between April 1, 2018, and March 31, 2021, were included. We extracted DNA from noncancerous areas of residual specimens after pancreaticoduodenectomy and determined PNPLA3 and TM6SF2 gene polymorphisms using real-time polymerase chain reaction. SLD was defined as a liver with an attenuation value of ≤40 HU or a liver-to-spleen ratio of ≤0.9 on computed tomography. We defined high hepatic fibrosis indexes (HFI) instead of steatohepatitis as a Fibrosis-4 index of ≥2.67 or nonalcoholic fatty liver disease fibrosis score of ≥0.675 in patients with SLD. The cumulative incidence of SLD (P = 0.299) and high HFI (P = 0.987) after pancreaticoduodenectomy were not significantly different between the PNPLA3 homozygous and minor allele groups. The incidences of high HFI at 1 year after pancreaticoduodenectomy were 16.8% and 27.0% in the TM6SF2 major homozygous and minor allele groups, respectively, with a significant difference in the cumulative incidence (P = 0.046). Conclusion The TM6SF2 minor allele may contribute to steatohepatitis development after pancreaticoduodenectomy.

J Gastrointest Surg 2024; 28:983-992. [PMID: 38552899 DOI: 10.1016/j.gassur.2024.03.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 02/19/2024] [Accepted: 03/22/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) occurs in 10% to 40% of patients after pancreatic resection. Pancreatic exocrine insufficiency (PEI) is thought to be closely associated with NAFLD; however, the mechanism of NAFLD is not clearly understood. We perform a systematic review and meta-analysis to better understand the risk factors of NAFLD. METHODS A systematic literature search was performed in the MEDLINE database. Studies focused on the risk factors associated with NAFLD in patients undergoing pancreatectomy. The odds ratios (ORs) denoting the association of risk factors with NAFLD after resection were curated. RESULTS Of 814 published articles, 26 studies met the inclusion criteria. Combined, these studies included clinical data on 4055 patients. The pooled incidence of NAFLD was 29% (23%-35%). Among the various risk factors analyzed, the following had a significant likelihood of NAFLD on forest plot analysis: female gender (OR, 2.44), pancreatic ductal adenocarcinoma (OR, 2.11), portal vein or superior mesenteric vein resection (OR, 1.99), dissection of nerve plexus around the superior mesenteric artery (OR, 1.93), and adjuvant chemotherapy (OR, 1.58). Only 2 studies investigated 2 different measurements of quantitative PEI, which could not be used for analysis. Owing to heterogeneity of studies, pancreatic remanent volume, which is considered a marker for PEI could not be evaluated. Pancreatic enzyme replacement therapy (PERT) was not associated with NAFLD. CONCLUSION Numerous factors are associated with NAFLD after pancreatectomy. Previous research shows that PEI may be associated with NAFLD; however, this could not be compared in our meta-analysis. Further research is required to study the role of PERT in NAFLD.

The Signal Intensity Ratio of Pancreas to Spleen in Magnetic Resonance Imaging Can Predict Nonalcoholic Fatty Liver Disease After Pancreaticoduodenectomy. Pancreas 2024; 53:e310-e316.

Abstract
OBJECTIVES Signal intensity ratio of pancreas to spleen (SI ratio p/s ) on fat-suppressed T1-weighted images of magnetic resonance imaging has been associated with pancreatic exocrine function. We here investigated the predictive value of the SI ratio p/s for the development of nonalcoholic fatty liver disease (NAFLD) after pancreaticoduodenectomy (PD). MATERIALS AND METHODS This study comprised 208 patients who underwent PD. NAFLD was defined as a liver-to-spleen attenuation ratio of <0.9 calculated by a computed tomography 1 year after surgery. SI ratio p/s was calculated by dividing the average pancreas SI by the spleen SI. We retrospectively investigated the association of clinical variables including the SI ratio p/s and NAFLD by univariate and multivariate analyses. RESULTS NAFLD after 1 year was developed in 27 patients (13%). In multivariate analysis, the SI ratio p/s < 1 ( P < 0.001) was an independent predictor of incidence of NAFLD. The SI ratio p/s < 1 was associated with low amylase level of the pancreatic juice ( P < 0.001) and progressed pancreatic fibrosis ( P = 0.017). According to the receiver operating characteristics curve, the SI ratio p/s had better prognostic ability of NAFLD than the remnant pancreas volume. CONCLUSIONS The SI ratio p/s is useful to predict NAFLD development after PD. Moreover, the SI ratio p/s can be a surrogate marker, which represents exocrine function of the pancreas.

Abstract
Steatohepatitis has been reported to occur after pancreaticoduodenectomy (PD). We report a case of steatohepatitis that arose after PD and led to decompensated liver cirrhosis and hepatocellular carcinoma (HCC). A 65-year-old man underwent PD for suspected intraductal papillary mucinous neoplasm. Eight years after PD, he was diagnosed with liver cirrhosis by laboratory tests and computed tomography. Histological examination of liver biopsy revealed hepatic steatosis, inflammation with ballooning of hepatocytes, and fibrosis, indicating nonalcoholic steatohepatitis as the cause of liver cirrhosis. Ten years after PD, he developed HCC and radiotherapy was performed because of impaired liver function. Intrahepatic metastasis appeared subsequently, but no further treatment could be performed due to decompensated liver cirrhosis. Survival time after PD is being prolonged by improvements in imaging studies and therapeutic strategies. Accordingly, we consider that progression to liver cirrhosis and HCC will occur increasingly in cases such as the present patient, which will become a severe problem in long-term post-PD survival. Therefore, it is necessary to clarify the precise mechanism of steatohepatitis after PD and establish appropriate therapeutic strategies.

Abstract
BACKGROUND The present study aimed to evaluate the association between estimated functional remnant pancreatic volume (eFRPV) and postoperative malnutrition after pancreaticoduodenectomy (PD). METHODS The medical records of 131 patients who underwent PD and preoperative computed tomography were retrospectively reviewed. Onodera's prognostic nutritional index (PNI) was assessed 6-months after PD. Patients with PNI values of at least 45 were included in the non-malnutrition group, while those with values <45 and <40 were included in the mild and severe malnutrition groups, respectively. Associations between eFRPV and postoperative nutritional status were evaluated to identify factors predictive of severe malnutrition after PD. RESULTS Fifty-three patients (40%) were included in the non-malnutrition group, while 38 (29%) and 40 (31%) were included in the mild and severe malnutrition groups, respectively. Overall survival was significantly shorter in the severe malnutrition group (p < 0.001). The eFRPV was significantly lower in the severe malnutrition group (p = 0.003; Jonckheere-Terpstra trend test, p < 0.001). In the multivariate analysis, eFRPV ≤55.2 mL·HU (odds ratio [OR] = 5.20; p = 0.004), preoperative PNI ≤41.9 (OR = 6.37; p = 0.010), and body mass index ≤19.1 kg/m2 (OR = 3.43; p = 0.031) were independent predictors of severe malnutrition after PD. CONCLUSION The current results indicate that eFRPV may predict low PNI values after PD.

Abstract
BACKGROUND/PURPOSE In the present study we aimed to prospectively assess the current prevalence and risk factors of nonalcoholic fatty liver disease (NAFLD) after total pancreatectomy (TP). METHODS Between August 2015 and December 2017, we prospectively collected data from 68 Japanese centers on 148 consecutive patients who underwent TP whose computed tomography (CT) attenuation values were evaluated for 12 months. We defined post-TP NAFLD as a liver parenchyma CT value of less than 40 Hounsfield units (HU). Data on perioperative variables were retrieved from all patients and evaluated using univariate and multivariate analyses to identify the perioperative risk factors of NAFLD. RESULTS In this prospective cohort study, supplementation of pancreatic exocrine enzymes was provided to all 148 patients, and 97% of them were treated with high-titer pancrelipase (median dosage: 1800 mg) postoperatively. Indeed, 29 patients (19.6%) developed NAFLD within a year after TP. Multivariate analysis revealed that female sex (P = .002), higher body mass index (BMI) (P = .001), and postoperative diarrhea (P = .038) were independent risk factors for post-TP NAFLD. However, post-TP NAFLD ameliorated in 11 patients (37.9%) at 12 months after surgery. CONCLUSIONS Among patients with risk factors such as female sex, higher BMI, and postoperative diarrhea, attention should be paid to the occurrence of NAFLD after TP.

Abstract
Pancreatic cancer is one of the most lethal gastrointestinal tumor entities. Surgery is the only chance for cure; however, only a minority of patients can be offered this option. Due to the anatomic location of the gland, tumor-related problems and complications affecting the surrounding structures are common, leading to biliary and gastric outlet obstruction as well as portal vein thrombosis. This review article summarizes the management of pancreatic cancer-related problems from a surgical point of view. We further describe surgical treatment options in unresectable, metastasized and recurring pancreatic cancer, highlighting potential resection of oligometastatic disease in selected settings.

Abstract
BACKGROUND This study aimed to determine the incidence of new onset hepatic steatosis after neoadjuvant chemotherapy for pancreatic cancer and its impact on outcomes after pancreatoduodenectomy. METHODS Retrospective review identified patients who received neoadjuvant chemotherapy for pancreatic adenocarcinoma and underwent pancreatoduodenectomy from 2013 to 2018. Preoperative computed tomography scans were evaluated for the development of hepatic steatosis after neoadjuvant chemotherapy. Hypoattenuation included liver attenuation greater than or equal to 10 Hounsfield units less than tissue density of spleen on noncontrast computed tomography and greater than or equal to 20 Hounsfield units less on contrast-enhanced computed tomography. RESULTS One hundred forty-nine patients received neoadjuvant chemotherapy for a median of 5 cycles (interquartile range (IQR), 4-6). FOLFIRINOX was the regimen in 78% of patients. Hepatic steatosis developed in 36 (24%) patients. The median time from neoadjuvant chemotherapy completion to pancreatoduodenectomy was 40 days (IQR, 29-51). Preoperative biliary stenting was performed in 126 (86%) patients. Neoadjuvant radiotherapy was delivered to 23 (15%) patients. Female gender, obesity, and prolonged exposure to chemotherapy were identified as risk factors for chemotherapy-associated hepatic steatosis. Compared with control patients without neoadjuvant chemotherapy-associated hepatic steatosis, patients developing steatosis had similar rates of postoperative pancreatic fistula (8% (control) vs. 4%, p = 0.3), delayed gastric emptying (8% vs. 14%, p = 0.4), and major morbidity (11% vs. 15%, p = 0.6). Ninety-day mortality was similar between groups (8% vs. 2%, p = 0.08). CONCLUSION Hepatic steatosis developed in 24% of patients who received neoadjuvant chemotherapy but was not associated with increased morbidity or mortality after pancreatoduodenectomy.
