High hand grip strength is a significant risk factor and a useful predictor of postoperative pancreatic fistula following pancreaticoduodenectomy.

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.

[Clinical Efficacy of Recombinant Human Thrombomodulin for Surgical Patients with Disseminated Intravascular Coagulation Associated with Oncologic Emergency].

AIM: We evaluated the clinical efficacy of recombinant human thrombomodulin(rTM)for surgical patients with disseminated intravascular coagulation syndrome(DIC)associated with an oncologic emergency(OE). SUBJECTS AND METHODS: Thirteen patients who underwent surgery for OE complicated with DIC and were treated with rTM in our institution were evaluated. We retrospectively analyzed the clinical changes of parameters in white blood cell count(WBC), platelet count, CRP, PT-INR and DIC scores after the rTM treatment. RESULTS: The average length of the days using rTM was 4.7 for 12 patients, excluding one who died within 30 days after surgery. Nine of 12 patients(75%)had DIC scores of less than 3 after the rTM treatment. WBC tended to decrease after the rTM treatment, without statistical difference. However, CRP, platelet count, PT-INR and DIC scores were significantly improved after the rTM treatment(p<0.05). CONCLUSIONS: rTM may be useful in the treatment of DIC for surgical OE patients.
