Background: The focus of this study was to understand the relationship between the failure of gut barrier function, inflammatory markers and septic complications after resection for extraperitoneal rectal cancer. Methods: One hundred seven patients were enrolled into this prospective observational study and underwent open colorectal resection for extraperitoneal cancer. All patients underwent an assessment of intestinal permeability (L/M ratio), endotoxemia, interleukin-1β (IL-1β), interleukin-6 (IL-6), C-reactive protein (CRP) and elastase levels before surgery and on postoperative days 1, 3, and 7. Results: Septic complications developed in 23.3% of patients. There were no significant differences in preoperative L/M ratio, endotoxine, CRP, interleukin-1 (IL-1), IL-6, and elastase levels between septic and non-septic groups. All patients showed a significant increase in intestinal permeability, endotoxemia, IL-1, IL-6, CRP, and elastase on the first postoperative day. At postoperative day 7, the septic group continued to demonstrate an increase in intestinal permeability, endotoxemia and elastase and significant difference was observed between the 2 groups (p < 0.05), whereas there was no significant difference in IL-1, IL-6, and CRP levels. Conclusion: The pattern of change in the postoperative period of intestinal permeability, systemic endotoxemia and elastase concentration is significantly higher in patients in whom sepsis develops, while the concentration of IL-1β, IL-6, and CRP does not permit to distinguish infection from inflammation.

Setting: Laparoscopic sleeve gastrectomy (LSG) is gaining popularity as a bariatric option. Gastric leak (GL) is the most dreaded septic complication of LSG. Early detection and treatment of this complication may improve outcomes. Objectives: This study investigates biomarkers that might be useful to predict GL before its clinical presentation in patients who underwent LSG. Patients and Methods: This study, prospective observational, was carried out in 151 patients, who underwent LSG for morbid obesity between February 2014 and October 2019. Blood samples were collected before the operation and on post-operative days one, three and five to dose serum C-reactive protein (CRP), pro-calcitonin (PCT), fibrinogen, white blood cells (WBCs) count and neutrophil-to-lymphocyte ratio (NLR). Results: GL occurred in 6 patients (3.97%). According to the receiver operating characteristics curve, NLR detected leak with remarkably higher sensitivity (100%) and specificity (100%) than CRP, fibrinogen, WBC on all the days and higher than PCT in post-operative days 3 and 5. Moreover, the area under the curve (AUC) of NLR (AUC = 1) was higher than the AUC of CRP, fibrinogen, WBC on all the days and higher than PCT in post-operative days 3 and 5, suggesting important statistical significance. Conclusions: Because NLR and PCT detected GL with remarkably higher sensitivity and specificity than CRP, fibrinogen and WBC, these two markers seem to be more accurate for the early detection of this complication.

This study demonstrated that high-concentration (80%) supplemental perioperative oxygen can lead to a reduction in postoperative inflammatory response and avoid postoperative immunosuppression.

Background:A number of studies have been reported on the effects of high-concentration oxygen (HCO) on cytokine synthesis, with controversial results. We assessed the effect of administration of perioperative HCO on systemic inflammatory and immune response in patients undergoing laparoscopic Nissen fundoplication (LNF).Materials and Methods:Patients (n = 117) were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n = 58) or 80% (n = 59). Administration was commenced after induction of anaesthesia and maintained for 6 h after surgery. White blood cells, peripheral lymphocytes subpopulation, human leucocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin (IL)-1 and IL-6 and C-reactive protein (CRP) were investigated.Results:A significantly higher concentration of neutrophil elastase, IL-1, IL-6 and CRP was detected post-operatively in the 30% FiO2group patients in comparison with the 80% FiO2group (P < 0.05). A statistically significant change in HLA-DR expression was recorded post-operatively at 24 h, as a reduction of this antigen expressed on monocyte surface in patients from 30% FiO2group; no changes were noted in 80% FiO2group (P < 0.05).Conclusions:This study demonstrated that perioperative HCO (80%), during LNF, can lead to a reduction in post-operative inflammatory response, and possibly, avoid post-operative immunosuppression.

Background: Laparoscopic anti-reflux surgery could be of benefit in a subset of elderly patients with gastroesophageal reflux disease. However, there are few reports that have evaluated the long-term results. This study examined the effects of age on the short- and long-term (for at least 5 years) outcomes after laparoscopic Nissen fundoplication (LNF). Patients and Methods: Patients were divided into four groups as follows: young (18–49); adult (50–69); and elderly (70–84), and very elderly (85–91). The database (recorded prospectively) included operating duration, conversion, intra- and early post-operative complication and late outcomes. Mean follow-up was 14.5 years (range 5–24 years). Results: Five hundred and sixty-nine patients met the inclusion criteria: young n = 219 (38.4%); adult n = 248 (43.5%); elderly n = 91 (16.0%) and very elderly n = 11 (1.9%). Hiatal hernia (type I and III) was significantly less frequent in young and adult patients ( P < 0.0001). The operation was significantly longer in elderly and very elderly patients ( P < 0.001); the use of drains ( P < 0.001) and grafts ( P < 0.0001) for hiatal hernia repair was less in young and adult patients. The hospital stay, conversion (5.4%), intra-operative and early post-operative complications were not influenced by age. Dysphagia was evenly distributed among the groups. Forty-eight (8.4%) patients had recurrence: 15 in the young group (6.8%), 18 in the adult group (7.2%), 11 in the elderly group (12%) and 4 in the very elderly group (36.3%) ( P < 0.0001). Conclusions: Age does not influence short- and long-term outcomes following LNF. Control of reflux in the elderly is worse than adult patients. Therefore, ageing is a relative contraindication to LNF.

Summary:Fournier’s gangrene is a rapidly progressing necrotizing fasciitis, involving perineal, perianal, or genital regions, and it constitutes a true surgical emergency. Surgical excision of all necrotic tissue is required, and multiple debridements may be necessary to remove all nonviable tissue. After surgical intervention for debridement, reconstruction may be necessary. We present our experience in the treatment of tissue loss after Fournier’s gangrene of genital and perianal regions with the use of biological mesh (derma porcine mesh) in association with vacuum-assisted closure therapy.
