Objectives:
The clinical study is aiming to discuss the therapeutic benefit of laparoscopic hernia (LH) repair with comparing conventional open hernia (OH) repair in incarcerated hernia in octogenarians.
Materials and Methods:
The clinical data of 29 octogenarian incarcerated hernia patients who underwent hernia repair from November 2013 to March 2017 were retrospectively analyzed. The variables analyzed include baseline, operation characteristics, and clinical outcomes. The patients were divided into LH and OH according to the surgical approach and their clinical parameters were compared. Descriptive statistics were calculated, and outcomes were compared using the Fisher exact test and the student t test, a P≤0.05 was considered significant.
Results:
Of reported 18 octogenarian patients, 7 patients underwent LH, whereas the remaining 11 patients underwent OH. The median age of the patients was 86 (81 to 97). All patients in LH group and 3 patients in OH group underwent nonmesh repair. In total, 8 patients in OH group underwent mesh repair. Simultaneous intestinal resection was needed in 4 patients (2 in LH, 2 in OH) due to the necrotic bowel. No mortality was observed in all subjects. The results showed significantly shorter operation time (50±5 vs. 110±3 min; P=0.000), hospital stay (6±1 vs. 12±3 d; P=0.04). There were no noteworthy postoperative complications and during the follow-up period, no patient experienced recurrent hernia in both groups.
Conclusions:
LH nonmesh repair has not increased the morbidity and mortality but showed shorter hospital stay and fast recovery and no recurrence in octogenarian incarcerated hernia patients. Therefore, LH in octogenarian incarcerated hernia patients might be preferred approach in sophisticated hands with acceptable outcomes.
Fluorodeoxyglucose (FDG) uptake by alveolar echinococcosis (AE) liver lesions is a signal of their metabolic activity and of disease progression. In order to find a surrogate marker for this status, we investigated whether parameters of the peripheral and/or periparasitic immune responses were associated with metabolic activity in a prospective case-control study of 30 AE patients and 22 healthy controls. Levels of 18 cytokines and chemokines, representative of innate and adaptive immune responses, were assessed in plasma and peripheral cells of two groups of patients with (MAAE) and without (MIAE) metabolically active lesions, and in the liver of MAAE patients. Mixed cytokine profile was observed in the peripheral blood of AE patients, with a predominance of Th2, Th17 and Treg responses. Among the detected markers only plasma IL-5 and IL-23, more elevated in MAAE patients, were found discriminant. Discrimination between MAAE and MIAE patients obtained by using IL-23 was improved when IL-5 was used in combination. The combination of elevated levels of IL-5 and IL-23 is significantly associated with FDG uptake at PET scan. It offers a new tool for the follow-up of AE patients which could substitute to FDG-PET whenever non-available to assess disease progression.
Several studies have demonstrated the important role of Toll-like receptors in various parasitic infections. This study aims to explore expression of Toll-like receptors (TLRs) and related cytokines in patients with human cystic echinococcosis (CE) and alveolar echinococcosis (AE). 78 subjects including AE group (N = 28), CE group (N = 22), and healthy controls (HC, N = 28) were enrolled in this study. The mRNA expression levels of TLR2 and TLR4 in blood and hepatic tissue and plasma levels related cytokines were detected by using ELISA. Median levels of TLR2 mRNA in AE and CE groups were significantly elevated as compared with that in healthy control group. Median levels of TLR4 expression were increased in AE and CE. Plasma concentration levels of IL-5, IL-6, and IL-10 were slightly increased in AE and CE groups compared with those in HC group with no statistical differences (p > 0.05). The IL-23 concentration levels were significantly higher in AE and CE groups than that in HC subjects with statistical significance. The increased expression of TLR2 and IL-23 might play a potential role in modulating tissue infiltrative growth of the parasite and its persistence in the human host.
Human alveolar echinococcosis (AE) is a lethal parasitic infectious disease which may lead to liver failure if left untreated. It is caused by the larval stage of the fox tapeworm Echinococcus multilocularis and usually develops a substantial infiltrative occupation in solid organs. During the infection, T helper subsets are known to play crucial role in crosstalk between the parasite and human host. Th9 cells, a new member of CD4+ T cell family which is characterized by its specific cytokine IL-9 and transcription factors PU.1 and IRF-4, have been known recently to have a critical role in allergic diseases, and cancers as well as the parasitic infection. To assess the potential role of Th9 cells during the infection, the mRNA levels of IL-9, PU.1, and IRF-4 both in peripheral blood mononuclear cells and in liver tissues were, respectively, detected by using real-time PCR. The plasma concentration levels of IL-9 were detected by using enzyme linked immunosorbent assay (ELISA). Th9 related cytokine IL-9 and transcription factors PU.1 and IRF-4 mRNA levels elevated both in PBMCs, and in hepatic lesion and paralesion tissues in AE patients. This may facilitate the infiltrative growth of the parasite and its persistence in human host.
