PURPOSE: It is generally recommended that the defect, after full thickness total wall excision of a tumour located in the extraperitoneal part of the rectum, should be sutured. There is a lack of controlled studies however, supporting this approach. The aim of this study was to compare the results obtained in patients after peranal local excision of rectal tumours whose defect were sutured with those that were not. METHODS: 44 patients were prospectively randomized to group A: The defect is closed; Group B: Defect left un-sutured. Pre-operative test were digital examination, proctoscopy and endorectal ultrasound. Local full-thickness excision was performed mainly with the Transanal Endoscopic Microsurgery (TEM) equipment, but for cases near the anal verge a Parks' retractor was used. Data recorded were operation time, blood loss, hospital stay and early and late complications. The first postoperative assessment was planned at 1 month and then every three months until 18 months of follow-up. Result for 40 patients (21 from group A; 19 from group B) were analysed. There were no differences between groups regarding age, sex, location of the tumour and specimen's size. RESULTS: The intra-operative loss of blood was 22 ml for group A and 39 ml for B, the difference was not significant. The mean operation time was slighter longer for group A (93 min) than for group B (77 min) but not statistically significant. For both group the mean hospital stay was of 4[2-7] days. No differences in early or late complications could be demonstrated. CONCLUSION: The present study suggests that there is no difference between these two practices in terms of intra-operative results and outcome.

The most complex bariatric procedures increase the effectiveness but unfortunately they also increase morbidity and mortality. LRYGBP is safe and effective for the treatment of morbid obesity. Modified BPD (75-225 cm) can be considered for the treatment of superobesity (body mass index > 50 kg/m(2)), and restrictive procedures such as VBG should only be performed in well-selected patients due to high rates of failure in long-term follow-up.

The only patient-related factor that significantly influences the incidence of incisional hernia in morbidly obese patients is body mass index.

Introduction Frailty studies focused on patients with infective endocarditis (IE) are scarce and its potential impact on patient outcomes is not well known. The aim of this study is to describe the clinical profile and prognosis of elderly patients with IE, comparing patients who met the frailty criteria versus those who did not. Methods A total of 121 cases of confirmed IE were consecutively collected in three tertiary hospitals between 2017 and 2019. The patients were classified into two groups: Group I (n=49), patients with IE who met the Frail criteria for frailty, and Group II (n=72), those patients without frailty by this scale. Results The median age of our cohort was 77 years (69–82), and 62.8% were men. Frail patients were older than those in Group II, as shown in Table 1. Regarding comorbidity, chronic anemia (40.8% vs 25%; p<0.060) was more common in Group I, as well as rheumatic manifestations at admission (12.2% vs 1.4%; p=0.014). The most frequently isolated microorganisms were S. aureus (n=25), coagulase negative staphylococci (n=25), viridans group streptococci (n=14), and enterococci (n=14). Enterococci (16.3% vs 8.3%, p=0.177) and non-viridans streptococci (10.2% vs 2.8%); p=0.086) were more frequent in frail patients. Vegetation (79.6% vs 80.6%; p=0.896) and periannular complications (24.5% vs 29.2%; p=0.571) were similar in both groups. No significant differences were found regarding the location of the infection. The incidence of in-hospital complications was similar between both groups. Frail patients underwent surgery less frequently than those in Group II, and had higher predicted mortality on surgical risk scale scores. However, the percentage of patients who met the surgical criteria and were considered inoperable was similar (33.3% vs 26.2%; p=0.415). In-hospital mortality was similar in both groups. When analyzing in-hospital mortality according to the therapeutic strategy in Group I, a mortality of 34.5% was observed in frail patients with conservative medical treatment, compared to 47.1% in those patients who underwent surgery in the same group. One third of our patients received outpatient antibiotic treatment, being significantly more frequent in Group I (39.6% vs 29.0%; p=0.232). Conclusions The elderly patients with IE and frailty criteria were older and more frequently had rheumatic symptoms at admission. Enterococci and non-viridans streptococci were isolated more frequently than in non-frailty patients. Surgery was less performed among frail patients, who had a higher predicted surgical risk. Although complications and in-hospital mortality were similar between both groups, in the group of frail patients, those with conservative management showed lower mortality compared to surgery.
