    PURPOSE: Laparoscopic hepatectomy (LH) is reported to cause less bleeding than open hepatectomy (OH) in obese patients; however, there are no reports addressing this issue in terms of body size-corrected bleeding. METHODS: The subjects of this study were 31 obese and 149 non-obese patients who underwent LH and 32 obese and 245 non-obese patients who underwent OH. Bleeding corrected for body surface area (C-BL) was compared between the obese and non-obese patients who underwent each procedure. A multivariate analysis for increased C-BL was performed using the median C-BL for each procedure. RESULTS: The median C-BL tended to be higher in the obese patients than in the non-obese patients who underwent LH, but there was no significant difference (72 vs. 42 mL/m2, P = 0.050). However, it was significantly higher in the obese patients than in the non-obese patients who underwent OH (542 vs. 333 mL/m2, P = 0.002). In a multivariate analysis, for OH, sectionectomy or more (OR 3.20, P < 0.001) and a high BMI (OR 2.76, P = 0.018) were found to be independent risk factors, whereas for LH, a high BMI was not (OR 1.58, P = 0.301). CONCLUSIONS: Obesity was identified as a risk factor for increased bleeding with body size correction for OH, but the risk was reduced for LH.

    BACKGROUND: Small intestine carcinoma (SIC) cases in Japan have recently been treated with chemotherapy according to colorectal carcinoma classification, while papilla of Vater carcinoma (PVC) cases according to cholangiocarcinoma (CHC) classification. However, few research reports support the molecular genetic validity of these therapeutic choices. PATIENTS AND METHODS: Here, we investigated the clinicopathological and molecular genetic factors of SIC and PVC. We used the data from the Japanese version of The Cancer Genome Atlas. Additionally, molecular genetic data on gastric adenocarcinoma (GAD), colorectal adenocarcinoma (CRAD), pancreatic ductal adenocarcinoma (PDAC), and CHC were also referred to. RESULTS: This study consisted of tumor samples from 12 patients of SIC and three patients of PVC treated from January 2014 to March 2019. Among them, six patients had pancreatic invasion. t-Distributed stochastic neighbor embedding analysis showed that the gene expression pattern of SIC was similar not only to those of GAD and CRAD, but also to that of PDAC in the pancreatic invasion patients. In addition, PVC resembled the GAD, CRAD, and PDAC, rather than the CHC. The molecular genetic characteristics of the six patients with pancreatic invasion were: one had high microsatellite instability, two had a TP53 driver mutation, and three had tumor mutation burden values <1 mutation/Mb with no driver mutation. CONCLUSIONS: In this study, the extensive gene expression profiling of organ carcinomas newly suggests that SIC or PVC may resemble GAD, CRAD, and PDAC. In addition, the data demonstrate that pancreatic invasive patients may be classified into several subtypes using molecular genetic factors.

    PURPOSE: An animal model of laparoscopic hepatectomy showed that bleeding from the hepatic vein is influenced by airway pressure. However, there are little research reports on how airway pressure leads to risks in clinical practice. The main objective of this study was to investigate the impact of preoperative forced expiratory volume % in 1 s (FEV1.0%) on intraoperative blood loss in laparoscopic hepatectomy. METHODS: All patients who underwent pure laparoscopic or open hepatectomy from April 2011 to July 2020 were classified into two groups by preoperative spirometry: those with obstructive ventilatory impairment (obstructive group; FEV1.0% < 70%) and those with normal respiratory function (ormal group; FEV1.0% ≥ 70%). Massive blood loss was defined as 400 mL for laparoscopic hepatectomy. RESULTS: In total, 247 and 445 patients underwent pure laparoscopic and open hepatectomy, respectively. Regarding laparoscopic hepatectomy group, blood loss was significantly greater in the obstructive group (122 vs. 100 mL, P = 0.042). Multivariate analysis revealed that high IWATE criteria which classify the surgical difficulty of laparoscopic hepatectomy (≥ 7, odds ratio (OR): 4.50, P = 0.004) and low preoperative FEV1.0% (< 70%, OR: 2.28, P = 0.043) were independent risk factors for blood loss during laparoscopic hepatectomy. In contrast, FEV1.0% did not affect the blood loss (522 vs. 605 mL, P = 0.113) during open hepatectomy. CONCLUSION: Obstructive ventilatory impairment (low FEV1.0%) may affect the amount of bleeding during laparoscopic hepatectomy.
