Redo-laparoscopy in the management of complications after laparoscopic colorectal surgery: a systematic review and meta-analysis of surgical outcomes.

BACKGROUND: The laparoscopic approach for colorectal surgery has gradually become widely accepted for the treatment of both benign and malignant diseases thanks to its several advantages over the open approach. However, it is associated with the same potential postoperative complications. Some recent studies have analyzed the potential role of laparoscopy in early diagnosis and management of complications following laparoscopic colorectal surgery. The aim of this systematic review was to investigate the outcomes of redo-laparoscopy (RL) for the management of early postoperative complications following laparoscopic colorectal surgery, focusing on length of stay, morbidity and mortality. METHODS: A systematic review of the literature was performed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines through MEDLINE (PubMed), Embase and Google Scholar from January 1990 to December 2019. The main outcomes examined were conversion rate, length of hospital stay, postoperative morbidity and mortality rates. A meta-analysis of all eligible studies was then conducted and forest plots were generated. RESULTS: A total of 19 studies involving 1394 patients who required reoperation after laparoscopic colorectal resection were included. In 539 (38.2%) of these patients, a laparoscopic approach was adopted. The most common indication for returning to the operating theater was anastomotic leakage (64.4% of all redo-surgeries, 67.7% of RL) and the most common type of intervention performed in RL was diverting stoma with or without anastomotic repair/redo (47.1%). Nine studies were included in the pooled analysis. The mean length of stay was significantly shorter in the RL group than in the redo-open one (WMD = - 0.90; 95% CI - 1.04 to - 0.76; Z = - 12,6; p < 0.001). A significantly lower risk of mortality was observed in the RL cohort (OR = - 0.91; 95% CI - 1.58 to - 0.23; Z = - 2.62; p = 0.009). CONCLUSIONS: Laparoscopy is a valid and effective approach for the treatment of complications following laparoscopic primary colorectal surgery thanks to it is well-established advantages over the open approach, which remain noticeable even in redo-surgeries.

Factors influencing delayed discharge after day-surgery laparoscopic cholecystectomy: the DeDiLaCo study protocol.

OBJECTIVE: Laparoscopic cholecystectomy (LC) is the gold standard for most benign gallbladder diseases. Early discharge (<24 hours) has the same outcomes as longer (>24 hours) hospital stay. Nevertheless, the rate of delayed discharge >24 hours range from 4.6% to 37%. The primary endpoint of this Italian nationwide study is to analyze the prevalence of patients undergoing elective LC who experienced a delayed discharge >24 hours and identify potential limiting factors of early discharge. Results from these analyses will be used to select patients who can be safely discharged on the same day after surgery. Secondary endpoints will be to evaluate the patient's quality of life (QoL), assess the direct health costs associated with late discharge, and quantify the patient's involvement in the treatment process. PATIENTS AND METHODS: This prospective, observational study was conducted following a resident-led model and the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines. All patients were treated according to the local hospital protocol and received routine care as standard therapy. RESULTS: We expected to obtain the enrollment of at least 500 patients based on an assumed difference in discharge delay between the reference and the recruitable population of 6% and the identification of factors related to discharge failure within 24 h. Early discharge after LC leads to advantages both in terms of clinical outcomes and quality of life of the patient, and it is highly effective in terms of health costs and shortening the waiting list. However, clinical reality differs from the results of randomized studies by a complex series of non-objectionable real-world data influencing treatment plans. Therefore, we expected to identify independent predictors and factors of failure of early discharge. CONCLUSIONS: Clinical reality often differs from randomized trial results. In Italy, the vast majority of delayed discharges after LC may not be related to surgery and can be prevented both with logistical reorganization and with a readjustment of the trust reimbursement policies.

Emergency hernia repair in the elderly: multivariate analysis of morbidity and mortality from an Italian registry.

PURPOSE: The incidence of inguinal hernia is higher in elderly because of aging-related diseases like prostatism, bronchitis, collagen laxity. A conservative management is common in elderly to reduce surgery-related risks, however watchful waiting can expose to obstruction and strangulation. The aim of the present study was to assess the impact of emergency surgery in a large series of elderly with complicated groin hernia and to identify the independent risk factors for postoperative morbidity and mortality. The predictive performance of prognostic risk scores has been also assessed. METHODS: This is a prospective observational study carried out between January 2017 and June 2018 in elderly patients who underwent emergency surgery for complicated hernia in 38 Italian hospitals. Pre-operative, surgical and postoperative data were recorded for each patient. ASA score, Charlson's comorbidity index, P-POSSUM and CR-POSSUM were assessed. RESULTS: 259 patients were recruited, mean age was 80 years. A direct repair without mesh was performed in 62 (23.9%) patients. Explorative laparotomy was performed in 56 (21.6%) patients and bowel resection was necessary in 44 (17%). Mortality occurred in seven (2.8%) patients. Fifty-five (21.2%) patients developed complications, 12 of whom had a major one. At univariate and multivariate analyses, Charlson's comorbidity index ≥ 6, altered mental status, and need for laparotomy were associated with major complications and mortality CONCLUSION: Emergency surgery for complicated hernia is burdened by high morbidity and mortality in elderly patients. Preoperative comorbidity played a pivotal role in predicting complications and mortality and therefore Charlson's comorbidity index could be adopted to select patients for elective operation.

Management of Small Bowel Obstruction (SBO) in older adults (>80 years): a propensity score-matched analysis on predictive factors for a (un)successful non-operative management (NOM).

OBJECTIVE: Small Bowel Obstruction (SBO) is a common emergency in older patients. The most appropriate treatment strategy is still matter of debate. The aim of this study was to compare a non-operative management (NOM) vs. a surgical procedure for patients ≥ 80 years with SBO. PATIENTS AND METHODS: All patients ≥ 80 years admitted to our Emergency Department (ED) for SBO between January 1st, 2015, and December 31st, 2020 were included in this study. In order to correct for baseline covariates and factors associated to clinical management, we used a 1:1 propensity score matching (PSM) analysis. The primary outcome was to compare the overall in-hospital mortality. Secondary outcomes included occurrence of major complications and in-hospital length of stay (LOS). RESULTS: A total of 561 patients were enrolled. After propensity score matching (PSM) analysis, 302 patients (151 each group) were included in the analysis. Mortality did not differ between the two groups. After PSM mechanical ventilation, sepsis, cumulative major complications, and LOS were significantly higher in the operative treatment group [15.9% vs. 1.5%, 9.4% vs. 4.1%, 27.6% vs. 19.2%, and 9.4 (6.4-14.3) days vs. 8.1 (4.5-13.3) days, respectively; p<0.001, p=0.013, p=0.025, and p=0.003, respectively]. CONCLUSIONS: In patients ≥ 80 years with SBO, a NOM could yield similar results, in terms of overall mortality, compared to a surgical management. Thus, particularly in patients with multiple comorbidities or functional impairments, a conservative approach should always be considered.

Acute intestinal ischemia in patients with COVID-19: single-centre experience and literature review.

OBJECTIVE: Acute Intestinal ischemia (AII) may involve the small and/or large bowel after any process affecting intestinal blood flow. COVID-19-related gastrointestinal manifestations, including AII, have been attributed to pharmacologic effects, metabolic disorders in ICU patients and other opportunistic colonic pathogens. AII in COVID-19 patients may be due also to "viral enteropathy" and  SARS-CoV-2-induced small vessel thrombosis. A critical appraisal of personal experience regarding COVID-19 and AII was carried out comparing this with a systematic literature review of published series. PATIENTS AND METHODS:   A retrospective observational clinical cohort study and a systematic literature review including only COVID-19 positive patients with acute arterial or venous intestinal ischemia were performed. The primary endpoint of the study was the mortality rate. Secondary endpoints were occurrence of major complications and length of hospital stay. RESULTS: Patient mean age was 62.9±14.9, with a prevalence of male gender (23 male, 72% vs. 9 female, 28%). The mean Charlson Comorbidity Index was 3.1±2.7. Surgery was performed in 24/32 patients (75.0%), with a mean delay time from admission to surgery of 6.0 ±5.6 days. Small bowel ischemia was confirmed to be the most common finding at surgical exploration (22/24, 91.7%). Acute abdomen at admission to the ED (Group 1) was observed in 10 (31.2%) cases, while 16 (50%) patients developed an acute abdomen condition during hospitalization (Group 2) for SARS-CoV-2 infection. CONCLUSIONS: Our literature review showed how intestinal ischemia in patients with SARS-CoV-2 has been reported all over the world. The majority of the patients have a high CCI with multiple comorbidities, above all hypertension and cardiovascular disease. GI symptoms were not always present at the admission. A high level of suspicion for intestinal ischemia should be maintained in COVID-19 patients presenting with GI symptoms or with incremental abdominal pain. Nevertheless, a prompt thromboelastogram and laboratory test may confirm the need of improving and fastening the use of anticoagulants and trigger an extended indication for early abdominal CECT in patients with suggestive symptoms or biochemical markers of intestinal ischemia.

[Enterobacteria and endotoxins in abdominal surgical pathology. Critical review and clinico-experimental studies]. / Enterobatteri ed endotossine nella patologia chirurgica addominale. Rassegna sintetico-critica e contributo clinico-sperimentale

A detailed critical review on the role of endotoxins from gram-negative bacteria in the pathogenesis of most of the intestinal experimental models of surgical interest is presented. Data of an investigation on 10 cases of acute appendicitis and 2 cases of intestinal occlusion associated with toxaemia are then presented: in all these cases the Limulus test significatively revealed the presence of endotoxin in the blood and in the peritoneal fluid, also in absence of bacteria in the blood. The implications of these results and the use of the test in clinical practice are discussed.

[Attempted protection against experimental endotoxic shock]. / Tentativi di protezione contro lo shock endotossinico sperimentale

Protection against endotoxin challenge. The AA. have summarized shortly some experimental data dealing with trials of protection against endotoxin challenge pointing out, mostly, the effects of phosphate-containing compounds, as well as dextrane, anticoagulants, platelets, polymyxin B, and serum antiendotoxin and Lipid A antiserum. They have reported some experiments carried out by means of Limulus amebocyte lysate.

[Effects of anesthesia and surgical trauma on the immune response of pediatric patients]. / Effetti della anestesia e del trauma operatorio sulla risposta immunitaria di pazienti in eta' pediatrica.

The AA. have evaluated the effects of anaesthesia and surgical trauma on the ability of lymphocytes from 10 patients to release Leukocyte Inhibiting Factor (LIF) after stimulation with phytohaemoagglutinin (PHA). In addition, they have studied the electrophoretic mobility of Polymorphonuclear-cells (PMN) and lymphocytes of 8 patients after incubation in autologus plasma. The experimental results show decrease of LIF production after operation in 6 individuals and reduction of eletrophoretic mobility of PMN and lymphocytes. The last finding is not significant on statistical point of view.
