RESUMO

INTRODUCTION: Parastomal hernias are frequent and highly recurrent. The sandwich technique is a combination of the keyhole and Sugarbaker techniques, using a double intraperitoneal mesh. The objective of this study was to assess the outcomes of the sandwich technique, specifically focusing on recurrence rates. MATERIALS AND METHODS: Observational retrospective study conducted in two tertiary referral centers in Catalonia, Spain. All consecutive patients who underwent parastomal hernia repair using the sandwich technique between 1st January 2016 and 31st December 2021 were included. RESULTS: A total of 38 patients underwent the laparoscopic sandwich technique for parastomal hernia repair. The overall recurrence rate was 7.9% (3/38), with a median follow-up of 39 months (IQR: 12.3-56.5). According to the EHS classification for parastomal hernia, there were 47.4% (18/38) type I defects, 10.5% (4/38) type II defects, 28.9% (11/38) type III defects, and 13.2% (5/38) type IV defects. The used mesh was predominantly TiMesh® (76.3%; 29/38), followed by DynaMesh® IPOM (23.7%; 9/38). Patients with recurrence exhibited higher rates of seroma, hematoma, surgical site infection, and one case of early recurrence attributed to mesh retraction. Consequently, postoperative complications emerged as the primary risk factor for hernia recurrence. CONCLUSION: The sandwich technique demonstrated recurrence rates consistent with those reported in the existing literature.

RESUMO

BACKGROUND: The guidelines recommend laparoscopic repair for bilateral inguinal hernia. However, few studies compare the totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) techniques in bilateral inguinal hernias. This study aimed to compare the outcomes of TEP and TAPP in bilateral inguinal hernia. METHODS: We conducted a retrospective cohort study of patients operated on for bilateral inguinal hernia by TEP and TAPP repair from 2016 to 2020. Intraoperative complications, operative time, acute postoperative pain, hospital stay, postoperative complications, chronic inguinal pain, and recurrence were compared. RESULTS: A total of 155 patients were included in the study. TEP was performed in 71 patients (46%) and TAPP in 84 patients (54%). The mean operative time was longer in the TAPP group than in the TEP group (107 min vs. 82 min, p < 0.001). The conversion rate to open surgery was higher in the TEP group than in the TAPP group (8.5% vs. 0%, p = 0.008). The mean hospital stay was longer in the TAPP group than in the TEP group (p < 0.001). We did not observe significant differences in the proportion of postoperative complications (p = 0.672), postoperative pain at 24 h (p = 0.851), chronic groin pain (p = 0.593), and recurrence (p = 0.471). We did not observe an association between the choice of surgical technique (TEP vs. TAPP) with conversion rate, operative time, hospital stay, postoperative complications, chronic inguinal pain, or hernia recurrence when performing a multivariable analysis adjusted for the male sex, age, BMI, ASA, recurrent hernia repair, surgeon, and hernia size > 3cm. CONCLUSIONS: Bilateral inguinal hernia repair by TEP and TAP presented similar outcomes in our study.

RESUMO

BACKGROUND AND AIM: Extracellular matrix (ECM) components released during excessive fat mass expansion are considered potential endogenous danger/alarm signals contributing to innate immune system activation. The aim of the current study was to specifically measure plasma levels of low molecular weight (LMW) hyaluronan (HA) and to evaluate its role as pro-inflammatory damage-associated molecular pattern (DAMP) on leukocyte response in the context of human obesity. SUBJECTS AND METHODS: Participants were selected according to their body mass index (BMI, kg/m2) as non-obese (BMI < 29.9, n = 18) and obese (BMI > 29.9, n = 33). Plasma samples were size-dependent fractionated using ion-exchange chromatography to specifically obtain LMW HA fractions that were subsequently quantified by ELISA. Cell incubation experiments with synthetic HA molecules were performed on freshly Ficoll-isolated neutrophils (PMN) and peripheral blood monocytes (PBMC). Leukocyte and adipose tissue gene expression was assessed by real-time PCR and NF-κB activation by western blot. Plasma cytokine levels were measured by fluorescent bead-based (Luminex) immunoassay. RESULTS: We observed a statistically significant increase in the circulating levels of HA fragments of LMW in individuals with obesity which were consistent with significant up-regulated expression of the LMW HA synthesizing enzyme hyaluronan synthase-1 (HAS-1) in obese adipose tissue. Gene expression assessment of HA receptors revealed up-regulated levels for TLR2 in both obese PMN and PBMC. Synthetic HA molecules of different sizes were tested on leukocytes from healthy donors. LMW HA fragments (15-40 kDa) and not those from intermediate molecular sizes (75-350 kDa) induced a significant up-regulation of the expression of major pro-inflammatory cytokines such as IL-1ß, MCP-1 and IL-8 in PBMC. Importantly, LMW HA was able to induce the phosphorylation of IKK α/ß complex supporting its pro-inflammatory role through NF-κB activation. CONCLUSION: Circulating LMW HA molecules are elevated in obesity and may play an important role in triggering low-grade inflammation and the development of metabolic complications.

RESUMO

INTRODUCTION: The population over 65 years old represents 40-50% of the all visits made to an emergency department (ED). Some situations of stress and dehumanization can occur due to user overflow. Our target is to identify factors influencing overall satisfaction of patients older than 65 attended in the ED, in order to identify points of conflict and improve the deficiencies in our care. MATERIAL AND METHOD: We performed a prospective study from September 2005-June 2006 with those patients who accepted to take part by filling an anonymous and confidential questionnaire. We evaluated 19 epidemiological variables, medical and related to the quality of information provided. A single bivariate analysis was performed (chi2, t-Student or logistic regression). RESULTS: The questionnaire was filled out by 1389 (31.3%) out of 4437 patients that could potentially be included in the study. Mean patient age was 77 +/- 6 years and more than half of them were women (64%). Of the responses, 82% rated their ED care as excellent or good. Variables significantly related to satisfaction were perception of a not-too-long waiting time (p = 0.001), having been attended to previously in the hospital (p = 0.050), having explained the tests that patients had to undergo (p = 0.002) and having been given clear information from staff (p = 0.001). CONCLUSIONS: In order to improve the quality of care given in the ED, the staff should give more personalized and clear information and reduce the patient perception that waiting time is too long.
