Comparison of GLIM, SGA, PG-SGA, and PNI in diagnosing malnutrition among hepatobiliary-pancreatic surgery patients

Objective

To compare the diagnostic value of four tools-the Global Leadership Initiative on Malnutrition (GLIM) criteria, the subjective global assessment (SGA), patient-generated subjective global assessment (PG-SGA), and prognostic nutritional index (PNI) in malnutrition among hospitalized patients undergoing hepatobiliary-pancreatic surgery. Meanwhile, to observe the nutritional intervention of these patients.

Methods

Present study was a cross-sectional study, including 506 hospitalized patients who underwent hepatobiliary-pancreatic surgery between December 2020 and February 2022 at Ningbo Medical Center Lihuili Hospital, China. The incidence rate of malnutrition was diagnosed using the four tools. The consistency of the four tools was analyzed by Cohen's kappa statistic. Data, including nutritional characteristics and nutritional interventions, were collected. The nutritional intervention was observed according to the principles of Five Steps Nutritional Treatment.

Results

The prevalence was 36.75, 44.58, and 60.24%, as diagnosed by the GLIM, PG-SGA, and PNI, respectively, among 332 tumor patients. Among the 174 non-tumor patients, the prevalence was 9.77, 10.92, and 32.18% as diagnosed by the GLIM, SGA, and PNI. The diagnostic concordance of PG-SGA and GLIM was higher (Kappa = 0.814, <0.001) than SGA vs. GLIM (Kappa = 0.752, P < 0.001) and PNI vs. GLIM (Kappa = 0.265, P < 0.001). The univariate analysis revealed that older age, lower BMI and tumorous were significantly associated with nutritional risks and malnutrition. Among 170 patients with nutritional risk, most of patients (118/170, 69.41%) did not meet the nutritional support standard.

Conclusion

The incidence of nutritional risk and malnutrition is high among patients with hepatobiliary and pancreatic diseases, specifically those with tumors. The GLIM showed the lowest prevalence of malnutrition among the four tools. The PG-SGA and GLIM had a relative high level of agreement. There was a low proportion of nutritional support in patients. More prospective and well-designed cohort studies are needed to confirm the relevance of these criteria in clinical practice in the future.

A nationwide certification system to increase the safety of highly advanced hepatobiliary-pancreatic surgery

BACKGROUND

To ensure that highly advanced hepatobiliary-pancreatic surgery (HBPS) is performed safely, the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHBPS) board certification system for expert surgeons established a safety committee to monitor surgical safety.

METHODS

We investigated postoperative mortality rates based on summary reports of numbers and outcomes of highly advanced HBPS submitted annually by the board-certified training institutions from 2012 to 2019. We also analyzed summary reports on mortality cases submitted by institutions with high 90-day post-HBPS mortality rates and recommended site visits and surveys as necessary.

RESULTS

Highly advanced HBPS was performed in 121 518 patients during the 8-year period. Thirty-day mortality rates from 2012 to 2019 were 0.92%, 0.8%, 0.61%, 0.63%, 0.70%, 0.59%, 0.48%, and 0.52%, respectively (P < .001). Ninety-day mortality rates were 2.1%, 1.82%, 1.62%, 1.28%, 1.46%, 1.22%, 1.19%, and 0.98%, respectively (P < .001). Summary reports were submitted by 20 hospitals between 2015 and 2019. Mortality rates before and after the start of report submission and audit were 5.72% and 2.79%, respectively (odds ratio 0.690, 95% confidence interval 0.487-0.977; P = .037).

CONCLUSIONS

Development of a system for designation of board-certified expert surgeons and safety management improved the mortality rate associated with highly advanced HBPS.

Platelet Activation Assessed by Glycoprotein VI/Platelet Ratio Is Associated With Portal Vein Thrombosis After Hepatectomy and Splenectomy in Patients With Liver Cirrhosis

Portal vein thrombosis (PVT) is a serious complication after hepatobiliary-pancreatic surgery. Portal vein thrombosis often develops in patients with liver cirrhosis (LC) postoperatively, although they have low platelet counts. Platelet activation is one of the causes of thrombosis formation, and soluble form of glycoprotein VI (sGPVI) has received attention as a platelet activation marker. We had prospectively enrolled the 81 consecutive patients who underwent splenectomy (Sx) and/or hepatectomy: these patients were divided as Sx (n = 38) and hepatectomy (Hx, n = 46) groups. The 3 patients who underwent both procedures were added to both groups. Each group was subdivided into patients with non-LC and LC: non-LC-Sx (n = 22) and LC-Sx (n = 16), non-LC-Hx (n = 40) and LC-Hx (n = 6). The presence of PVT was diagnosed by using enhanced computed tomography (CT) scan. Platelet counts were significantly lower in LC-Sx than in non-LC-Sx, and incidence of PVT was significantly higher in LC-Sx than in non-LC-Sx (68.8% vs 31.8%, P = .024). Soluble form of glycoprotein VI /platelet ratios on preoperative day and postoperative day 1 were significantly higher in LC-Sx than in non-LC-Sx. Incidence of PVT was significantly higher in LC-Hx than in non-LC-Hx (50.0% vs 7.5%, P < .01). Soluble form of glycoprotein VI /platelet ratios were significantly higher in LC-Hx before and after Hx, compared to non-LC-Hx. Patients with LC stay in hypercoagulable state together with platelet activation before and after surgery. Under this circumstance, alteration of portal venous blood flow after Sx or Hx is likely to cause PVT in patients with LC.
