Abstract
BACKGROUND Portal vein thrombosis (PVT) is a commonthsn complication after splenectomy in patients with cirrhosis. However, the predictors of postoperative PVT are not known. AIM To investigate the predictors of PVT after splenectomy in patient with cirrhosis. METHODS A total of 45 patients with cirrhosis who underwent splenectomy were consecutively enrolled from January 2017 to December 2018. The incidence of PVT at 1 months, 3 months, and 12 months after splenectomy in patients with cirrhosis was observed. The hematological indicators, biochemical and coagulation parameters, and imaging features were recorded at baseline and at each observation point. The univariable, multivariable, receiver operating characteristic curve and time-dependent curve analyses were performed. RESULTS The cumulative incidence of PVT was 40.0%, 46.6%, and 48.9% at 1 months, 3 months, and 12 months after splenectomy. Multivariable analysis showed that portal vein diameter (PVD) ≥ 14.5 mm and monthsdel end-stage liver disease (MELD) score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy (P < 0.05). Time-dependent curve showed that the cumulative incidence of PVT was significantly different between patients with MELD score ≤ 10 and > 10 (P < 0.05). In addition, the cumulative incidence of PVT in the PVD ≥ 14.5 mm group was significantly higher than that in the PVD < 14.5 mm group (P < 0.05). CONCLUSION Wider PVD and MELD score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy in patient with cirrhosis.

Nomogram-based prediction of portal vein system thrombosis formation after splenectomy in patients with hepatolenticular degeneration. Front Med (Lausanne) 2023; 10:1103223. [PMID: 36910478 PMCID: PMC9996067 DOI: 10.3389/fmed.2023.1103223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Accepted: 02/07/2023] [Indexed: 02/25/2023] Open
Abstract
Objective Splenectomy is a vital treatment method for hypersplenism with portal hypertension. However, portal venous system thrombosis (PVST) is a serious problem after splenectomy. Therefore, constructing an effective visual risk prediction model is important for preventing, diagnosing, and treating early PVST in hepatolenticular degeneration (HLD) surgical patients. Methods Between January 2016 and December 2021, 309 HLD patients were selected. The data were split into a development set (215 cases from January 2016 to December 2019) and a validation set (94 cases from January 2019 to December 2021). Patients' clinical characteristics and laboratory examinations were obtained from electronic medical record system, and PVST was diagnosed using Doppler ultrasound. Univariate and multivariate logistic regression analyses were used to establish the prediction model by variables filtered by LASSO regression, and a nomogram was drawn. The area under the curve (AUC) of receiver operating characteristic (ROC) curve and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the differentiation and calibration of the model. Clinical net benefit was evaluated by using decision curve analysis (DCA). The 36-month survival of PVST was studied as well. Results Seven predictive variables were screened out using LASSO regression analysis, including grade, POD14D-dimer (Postoperative day 14 D-dimer), POD7PLT (Postoperative day 7 platelet), PVD (portal vein diameter), PVV (portal vein velocity), PVF (portal vein flow), and SVD (splenic vein diameter). Multivariate logistic regression analysis revealed that all seven predictive variables had predictive values (P < 0.05). According to the prediction variables, the diagnosis model and predictive nomogram of PVST cases were constructed. The AUC under the ROC curve obtained from the prediction model was 0.812 (95% CI: 0.756-0.869) in the development set and 0.839 (95% CI: 0.756-0.921) in the validation set. Hosmer-Lemeshow goodness-of-fit test fitted well (P = 0.858 for development set; P = 0.137 for validation set). The nomogram model was found to be clinically useful by DCA. The 36-month survival rate of three sites of PVST was significantly different from that of one (P = 0.047) and two sites (P = 0.023). Conclusion The proposed nomogram-based prediction model can predict postoperative PVST. Meanwhile, an earlier intervention should be performed on three sites of PVST.

Abstract
Background and aims Portal hypertension (PHT) is common in end-stage cirrhosis, and variceal bleeding is the main complication associated with mortality. Surgery is usually performed in patients with PHT with a high risk of variceal bleeding in China. This study aimed to introduce an individualized and precise total laparoscopic surgical procedure based on 3D remodeling for PHT. Methods From March 2013 to December 2018, 146 patients with cirrhotic PHT underwent a laparoscopic surgical procedure in our department. An individualized 3D remodeling evaluation was carried out for surgical planning. Results The operation time was 319.96 ± 91.53 min. Eight of 146 patients were converted to open surgery. Acute portal vein system thrombosis occurred in 10 patients (6.85%). During the first year, 11 patients (8.15%) experienced rebleeding and two (1.48%) died. 18 patients (13.33%) experienced rebleeding and three died, giving a 3-year mortality rate of 3.66%. Compared with preoperatively, the portal vein showed significant postoperative decreases in diameter, flow velocity, and flow amount, while the hepatic artery showed significant postoperative increases in diameter, flow velocity, and flow amount. A 3D liver volume evaluation found that 19 of 21 patients had a significantly increased liver volume postoperatively, and a significantly decreased MELD score. Conclusion This retrospective study introduced a safe, feasible, and effective individualized surgical procedure. Our results show that this surgical treatment may not only act as an effective symptomatic treatment for PHT to prevent esophageal and gastric hemorrhage, but also as an etiological treatment to increase liver function and long-term survival.

Liu Y, Fu Y, Fan L. Endoclip migration after laparoscopic splenectomy combined with pericardial devascularization: Case report and literature review. Int J Surg Case Rep 2022; 92:106806. [PMID: 35158233 PMCID: PMC8850752 DOI: 10.1016/j.ijscr.2022.106806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 01/20/2022] [Accepted: 01/30/2022] [Indexed: 11/26/2022] Open
Abstract
Introduction and importance Endoclip migration(ECM) after laparoscopic splenectomy combined with pericardial devascularization (LESD) is a rare and dangerous postoperative complication. The emergence of such cases led to our consideration of the timing of use of nonabsorbable endoclips. Case presentation This case report describes a patient with cirrhosis and portal hypertension who underwent LESD. Two years after the operation, an endoclip was found in the fornix of the fundus of his stomach by gastroscopy. Clinical discussion A 66-year-old male patient had a history of liver cirrhosis for 9 years. Two years prior, LESD was performed on this patient in our hospital. This time, due to ‘repeated black stool for 1 month, and hematemesis 1 time’, the patient was admitted to the hospital. A diagnosis of ‘liver cirrhosis with esophageal and gastric variceal bleeding’ was considered. Gastroscopy revealed a fundal foreign body, and upon review of the patient history, the foreign body was found to be a nonabsorbable endoclip. Conclusion Foreign literature has reported cases of biliary endoclip migration after laparoscopic cholecystectomy, but no cases of ECM after LESD have been reported. For such cases, we should consider the timing of the application of nonabsorbable endoclips during vascular devascularization to avoid ECM after the operation. In addition, we should also comprehensively evaluate whether the ectopic endoclips should be removed. This is the first case report of endoclip migration from the lateral gastric cavity to gastric cavity. A patient was found an endoclip in his stomach by gastroscopy after laparoscopic splenectomy combined with pericardial devascularization. The mechanism of endoclip migration from the lateral gastric cavity to the gastric cavity remains unclear and is worth exploring. Through the case report, we should pay attention to the implementation of endoclips in laparoscopic splenectomy combined with pericardial devascularization.
