RESUMEN
Background: Peritoneal lesions present diagnostic challenges, necessitating precise imaging techniques. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) offers a promising approach for accurate diagnosis, aiding in optimal patient management and treatment planning. Objective: This study aims to assess the diagnostic efficacy of EUS-FNA in peritoneal lesions to offer insight in guiding optimal patient management. Methods: A prospective observational study was conducted, and a total of 58 patients who underwent EUS-FNA of the peritoneum at our hospital between October 2021 and November 2021 were included. The ultrasound diagnostic instrument facilitated puncture guidance, with 2-5 punctures performed in various parts of the selected peritoneal lesion areas. The analysis encompassed evaluating the sensitivity, specificity, positive predictive value, and negative predictive value of biopsy for diagnosing peritoneal-associated lesions, alongside assessing the number of punctures, puncture satisfaction, and incidence of postoperative complications. Results: The included patients undergoing EUS-FNA revealed that 41 (70.69%) had malignant lesions, while 17 (29.31%) presented with benign lesions. The diagnostic accuracy of EUS-FNA for peritoneal lesions was determined to be 94.83%, with a diagnostic sensitivity of 97.30% for malignant tumors, specificity of 90.48%, positive predictive value of 94.74%, and negative predictive value of 95%. Lesions exhibited a size range of 2.5cm × 2.9cm to 15.2cm × 9.8cm. Each patient underwent 2-5 punctures (3.3 ± 1.4), with a puncture satisfaction rate of 96.55%. The incidence of postoperative complications following EUS-FNA was found to be 3.45%. Conclusion: EUS-FNA exhibits substantial diagnostic utility for peritoneal-related lesions, marked by exceptional accuracy, sensitivity, specificity, and favorable safety. Its clinical adoption is warranted, promising improved patient care and management.
RESUMEN
BACKGROUND: The treatment of choledocholithiasis by endoscopic retrograde cholangiopancreatography (ERCP) is a difficult endoscopic procedure involving a complicated surgical process. During and after ERCP, surgery-related complications may occur, and serious complications can threaten the life of the patient. This study aims to evaluate the correlation between the possible complications of ERCP treatment of choledocholithiasis and the quality of life of patients, and to provide a basis for formulating corresponding intervention measures. METHODS: Using the Gastrointestinal Quality of Life Index (GIQLI) and the MOS item short from health survey (SF-36), we conducted random telephone follow-ups of 194 patients admitted to The Second Affiliated Hospital of Soochow University who underwent ERCP for the treatment of choledocholithiasis from October 2017 to December 2020. The patients' complications symptoms and quality of life were recorded, and a comparative analysis was performed. RESULTS: During the hospitalization of the included 194 patients, complications occurred in 38 cases (19.6%), including 18 cases (9.3%) of hyperamylase, 11 cases (5.7%) of acute pancreatitis, and 5 cases (2.6%) of cholecystitis. There were 4 cases (2.1%) of gastrointestinal bleeding. The SF-36 scores in the complication group were significantly lower than those in the non-complication group across various dimensions, including bodily pain (BP), general health (GH), vitality (VT), social functioning (SE), and mental health (MH). Furthermore, the GIQLI scores in the complication group were lower than those in the non-complication group across various dimensions, including symptoms, subjective symptoms, physical function status, social activity status, as well as mental and psychological status. Multiple regression analysis showed that dimensions such as PF, BP, and subjective symptoms were more likely to be affected by hyperamylaseemia, acute pancreatitis, and cholecystitis, and the difference was statistically significant (P<0.05). CONCLUSIONS: Complications after ERCP result in a poor quality of life after discharge in choledocholithiasis patients, suggesting that nurses need to take effective measures to prevent and actively treat hyperamylase, acute pancreatitis, and acute pancreatitis during the hospitalization of holedocholithiasis patients after ERCP. Common complications, such as cholecystitis, promote the recovery of patients and reduce the impact of the disease on quality of life.

BACKGROUND/OBJECTIVES: Lysosomal/autophagic pathway plays important role in the early onset of acute pancreatitis (AP). However, its role in the later recovery phase of AP is unknown. This study aims to investigate the role of lysosomal/autophagic pathway in the self-limited program of AP and elucidate the underlying mechanisms. METHODS: AP was induced in the rat by 3% sodium taurocholate injection in the pancreaticobiliary duct. Serum amylase activity assay, histological examination, and cell death detection were used to assess the time course of AP severity. Meanwhile, the expression of LC3-II, p62 and Lamp-2 was measured to evaluate the status of autophagic flux. S6RP phosphorylation was detected to determine the time course of mTOR activation. Rapamycin was administered to block mTOR activity. RESULTS: AP developed in the rats to the most severe at 24 h but tended to self-restore at 36 and 48 h. The impairment of autophagic flux characterized by the accumulation of LC3-II and p62 and the depletion of Lamp-2 occurred at 24 h after AP induction followed by the restoration over the following 24 h. Furthermore, the phosphorylation of S6RP was increased at 36 and 48 h after AP induction despite the initial inhibition. Rapamycin treatment reduced the level of phospho-S6RP and inhibited the restoration of autophagic homeostasis and pancreatic tissue injury. CONCLUSIONS: Activation of mTOR is correlated with the improvement of autophagic flux and pancreatic injury, suggesting that mTOR activation plays a potential protective role in the later recovery of AP.

OBJECTIVE: To explore the protective effects and possible mechanism of lipoxin A(4)-methyl ester (LXA(4)-ME) in rats with acute pancreatitis (AP). METHODS: A total of 120 male SD rats were randomly divided into 3 groups: Sham operation (n = 40), AP (n = 40) and LXA(4)-ME (n = 40). Sham operation group received normal saline after sham operation. AP was induced by a retrograde infusion of 5% sodium taurocholate into pancreatobiliary duct. AP group received normal saline after modeling. In the LXA(4)-ME group, LXA(4)-ME was administered (87.5 µg/kg) intravenously after the onset of AP. The rats were sacrificed at 12 h and 24 h post-induction. Their serum levels of amylase were detected. The amount of ascites was calculated and histological changes of pancreas were observed. The activities of myeloperoxidase (MPO) and levels of malonaldehyde (MDA) in pancreas were determined. The mRNA levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1ß, IL-10, intercellular adhesion molecule (ICAM-1), E-selectin and nuclear factor (NF)-κB p65 in pancreas were measured by reverse transcription-polymerase chain reaction (RT-PCR). The expression of NF-κB p65 protein was also measured by immunohistochemistry. RESULTS: Compared with the AP group, the pathological scores of the LXA(4)-ME group improved (12 h: 8.7 ± 1.3 vs 11.3 ± 1.5, 24 h: 7.8 ± 1.1 vs 11.7 ± 0.8) and the amount of ascites was lower(12 h: (6.88 ± 1.23) ml vs (12.32 ± 1.94) ml, 24 h: (6.53 ± 0.91) ml vs (14.15 ± 1.68) ml, all P < 0.01). The serum levels of amylase in the LXA(4)-ME group were significantly lower than those in the AP group respectively at 12 h and 24 h post-operation (all P < 0.01). The activity of MPO and the level of MDA in pancreas in the LXA(4)-ME group were significantly lower than those in the AP group (all P < 0.01). The pancreatic expressions of TNF-α mRNA, IL-1ß mRNA, ICAM-1 mRNA, E-selectin mRNA and NF-κB p65 mRNA at 12 h and 24 h decreased in the LXA(4)-ME group versus the AP group at the corresponding time points (all P < 0.01)while the expression of IL-10 mRNA increased versus the AP group at the corresponding time points (all P < 0.01). Compared with that in the AP group, the pancreatic expression of NF-κB p65 protein decreased in the LXA(4)-ME group (12 h: 24.8% ± 3.0% vs 45.3% ± 3.4%, 24 h: 31.6% ± 3.0% vs 48.1% ± 4.6%, both P < 0.01). CONCLUSION: LXA(4)-ME exerts protective effects in AP rats. And its mechanism may be due to the suppression of NF-κB activation.
