Small bowel emergency surgery: literature's review

Emergency surgery of the small bowel represents a challenge for the surgeon, in the third millennium as well. There is a wide number of pathologies which involve the small bowel. The present review, by analyzing the recent and past literature, resumes the more commons. The aim of the present review is to provide the main indications to face the principal pathologies an emergency surgeon has to face with during his daily activity

Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy

IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

Outcomes of pelvic exenteration for recurrent and primary locally advanced rectal cancer

Background Pelvic exenteration is the only radical treatment for locally advanced (ARC) or recurrent (RRC) rectal cancers. The long-term results of the procedure are variably reported in the literature, with recent series suggesting similar survival between ARC and RRC. The study aimed to analyze and compare the long-term survival and perioperative outcomes of patients undergoing pelvic exenteration for ARC and RRC in a tertiary center. Materials and methods This was a retrospective analysis of prospectively collected data. Comparison of variables was performed using Chi-square, Fisher's exact or Wilcoxon rank sum test as appropriate. The Kaplan Meier method was used to analyze the disease-free survival (DFS) and the log-rank test to compare the two groups. Results Since 2002, 46 patients underwent pelvic exenteration for ARC (28, 60.9%) and RRC (18, 39.1%). The groups had comparable characteristics, perioperative results, including postoperative complications, and rate of adjuvant chemotherapy. A R0 resection was obtained in 71.4% and 55.6% (p 0.41) and a T4 stage was diagnosed in 75% and 94.4% (p 0.22) of ARC and RRC patients, respectively. After a median follow-up time of 32.5 and 56.6 months (p 0.01), the 5-year DFS was significantly lower in the RRC group (23.6 vs 46.2%, p 0.006), even after exclusion of R1 cases (30 vs 54.5%, p 0.044). Conclusion The long-term disease free survival of patients undergoing pelvic exenteration is significantly worse when the procedure is performed for RRC, regardless of the tumor involvement of the resection margins

Gracilis muscle transposition for the treatment of recurrent rectovaginal and pouch-vaginal fistula: is Crohn's disease a risk factor for failure? A prospective cohort study

BACKGROUND: The surgical management of rectovaginal fistulae associated with Crohn's disease is often frustrated by poor results regardless of the different techniques. The outcomes of the gracilis muscle transposition (GMT) for the treatment of recurrent Crohn's-associated fistulae are still debated. The aim of the study is to determine whether the success rate of GMT is similar in Crohn's disease patients and in a control group. MATERIALS AND METHODS: All patients undergoing GMT for rectovaginal or pouch-vaginal fistula were collected from a prospectively maintained database (2005-2016). The primary study outcome was the comparison of the success rate of GMT in Crohn's disease and control group patients. RESULTS: Twenty-one patients with a rectovaginal fistula due to Crohn's disease (8, 38.1%) or other etiologies (13, 61.9%) were included. The groups had similar characteristics and postoperative outcomes. After a median follow-up time of 81 and 57 months (p 0.34), the success rate of GMT was 75% in patients with Crohn's disease and 68.4% in control group (p 0.6). The median time to recurrence was 3.5 months (1-12). The success rate in patients who had more than two previous attempts of repair was lower regardless of the etiology (50 vs 79.4%, p 0.1). CONCLUSION: GMT is associated with a high success rate, especially in Crohn's disease-related rectovaginal fistula. In consideration of the low morbidity rate and the fact that an increasing number of previous local operations might be associated with failure, the procedure should be considered as a first line of treatment for recurrent rectovaginal fistulae

Transabdominal salvage surgery after pouch failure in a tertiary center: a case-matched study

Background: Salvage surgery after failure of ileal pouch-anal anastomosis (IPAA) could be offered to selected patients. However, the results vary widely in different centers. Aims: To assess the outcomes of salvage surgery by comparison with a control group matched for confounding variables. Methods: From a prospective database of 1286 IPAA, patients undergoing transabdominal salvage surgery were compared for perioperative and functional outcomes and quality of life (QOL) to a 1:3 control group of primary IPAA cases. Results: Salvage surgery patients (30) had a higher rate of hand-sewn anastomoses (80 vs 20%, p <. 0.0001) and reoperations (10 vs 2.2%, p 0.02) than control group (90). A higher number of daytime and nighttime bowel movements (7.4 vs 4.1, p <. 0.0001, and 2.6 vs 1.8, p = 0.002), a lower median CGQL score (0.7 vs 0.8, p = 0.0001) and a higher rate of pouch fistulae (13.3 vs 1.1%, p = 0.003) were reported after salvage surgery. Pouch failure rate after salvage surgery was 10.1%, 18.7% and 26.8% at 1, 5 and 10 years (vs 0%, 3.5% and 8.4% in control group, p = 0.0085). Conclusions: Although worse functional outcomes and decreased QOL have to be expected, salvage surgery after pouch failure is associated with acceptable outcomes when performed in a referral center

Antibiotic Prophylaxis for Surgical Site Infection in General Surgery: Oncological Treatments and HIPEC

The procedure of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a combined surgical and oncological treatment for peritoneal carcinomatosis of various origins. Antibiotic prophylaxis is usually center-related and should be discussed together with the infectious disease specialist, taking into account the advanced oncologic condition of the patient, the complexity of surgery—often requiring multiorgan resections—and the risk of post-HIPEC neutropenia. The incidence of surgical site infection (SSI) after CRS and HIPEC ranges between 11 and 46%. These patients are also at high risk of postoperative abdominal infections and septic complications, and a bacterial translocation during HIPEC has been hypothesized. Many authors have proposed aggressive screening protocols and a high intra and postoperative alert, in order to minimize and promptly identify all possible infectious complications following CRS and HIPEC

P070 Outcomes of hand-sewn versus stapled anastomosis for loop ileostomy reversal after ileal pouch-anal anastomosis in a tertiary center (12th Scientific and Annual Meeting of the European Society of Coloproctology, 20\u201322 September 2017, CityCube, Berlin, Germany)

Aim: There is evidence towards superiority of stapled closure of loop ileostomy after low rectal anastomosis compared to hand suture in terms of operative time and bowel obstruction rate. The aim of this study is to compare the 30-day outcomes of the two techniques for ileostomy closure after ileal pouch-anal anastomosis (IPAA). Method: Consecutive patients undergoing ileostomy closure after IPAA between 2011\u20132106 were retrospectively included. Patients\u2019 characteristics and perioperative outcomes were compared. Results: Hand-sewn suture and stapled anastomosis were performed in 280 (84.3%) and 52 (15.7%) patients. The two groups had comparable demographic characteristics. The median operative time was the same between groups (90 min). The incidence of Clavien-Dindo grade I (6.4% vs. 9.6%), II (4.3% vs. 1.9%) and IIIb (1.4% vs. 3.8%), the median days to flatus (2 vs. 2.5, P 0.3) and the length of hospital stay (6 days in both, P 0.9) were similar between groups. A slightly higher although non-significant rate of bowel obstruction was observed in the stapled group (3.8% vs. 2.5%, P 0.6). Conclusion: The loop ileostomy after IPAA should be closed according to the surgeon\u2019s preference using indifferently the hand-sewn or the stapled technique, as the expected outcomes are similar

Sepsis Team Organizational Model to Decrease Mortality for Intra-Abdominal Infections: Is Antibiotic Stewardship Enough?

Introduction. Sepsis is an overwhelming reaction to infection with significant morbidity, requiring urgent interventions in order to improve outcomes. The 2016 Sepsis-3 guidelines modified the previous definitions of sepsis and septic shock, and proposed some specific diagnostic and therapeutic measures to define the use of fluid resuscitation and antibiotics. However, some open issues still exist. Methods. A literature research was performed on PubMed and Cochrane using the terms &ldquo;sepsis&rdquo; AND &ldquo;intra-abdominal infections&rdquo; AND (&ldquo;antibiotic therapy&rdquo; OR &ldquo;antibiotic treatment&rdquo;). The inclusion criteria were management of intra-abdominal infection (IAI) and effects of antibiotic stewardships programs (ASP) on the outcome of the patients. Discussion. Sepsis-3 definitions represent an added value in the understanding of sepsis mechanisms and in the management of the disease. However, some questions are still open, such as the need for an early identification of sepsis. Sepsis management in the context of IAI is particularly challenging and a prompt diagnosis is essential in order to perform a quick treatment (source control and antibiotic treatment). Antibiotic empirical therapy should be based on the kind of infection (community or hospital acquired), local resistances, and patient&rsquo;s characteristic and comorbidities, and should be adjusted or de-escalated as soon as microbiological information is available. Antibiotic Stewardship Programs (ASP) have demonstrated to improve antimicrobial utilization with reduction of infections, emergence of multi-drug resistant bacteria, and costs. Surgeons should not be alone in the management of IAI but ideally inserted in a sepsis team together with anaesthesiologists, medical physicians, pharmacists, and infectious diseases specialists, meeting periodically to reassess the response to the treatment. Conclusion. The cornerstones of sepsis management are accurate diagnosis, early resuscitation, effective source control, and timely initiation of appropriate antimicrobial therapy. Current evidence shows that optimizing antibiotic use across surgical specialities is imperative to improve outcomes. Ideally every hospital and every emergency surgery department should aim to provide a sepsis team in order to manage IAI

Predictors of early recurrence after strictureplasty for Crohn's disease of the small bowel during the years of biologics

Background: The identification of patients prone to early recurrence of Crohn's disease at the site of a strictureplasty is fundamental in the clinical practice. Aims: Aim of the study is to detect the risk factors for early reoperation for recurrence after primary strictureplasty. Methods: From 2000, patients undergoing a primary strictureplasty and a subsequent reoperation for recurrence of Crohn's disease at the site of a strictureplasty were included. Univariate and multivariable linear regression models were performed to analyse the relationship between the time to recurrence and independent variables. Results: Fifty-nine patients were included. Median time to recurrence was 4.5 years (0.7\u201312.6). At the multivariate linear regression, early relapse was significantly associated with use of biologics before primary surgery ( 122.69, p &lt; 0.0001) and location of disease in the ileum ( 121.61, p 0.017). The use of biologics after surgery was similar between groups (40.7 vs 37.5%, p 0.79). Conclusions: The location of Crohn's disease in the ileum and the use of biologics before surgery are strong predictors of early site-specific recurrence after strictureplasty. In this group of patients, a tailored follow-up and aggressive postoperative treatment should be considered

Antibiotic De-Escalation in Emergency General Surgery

Background. Antibiotic treatment in emergency general surgery (EGS) is a major challenge for surgeons, and a multidisciplinary approach is necessary in order to improve outcomes. Intra-abdominal infections are at high risk of increased morbidity and mortality, and prolonged hospitalization. An increase in multi-drug resistance bacterial infections and a tendency to an antibiotic overuse has been described in surgical settings. In this clinical scenario, antibiotic de-escalation (ADE) is emerging as a strategy to improve the management of antibiotic therapy. The objective of this article is to summarize the available evidence, current strategies and unsolved problems for the optimization of ADE in EGS. Methods. A literature search was performed on PubMed and Cochrane using &ldquo;de-escalation&rdquo;, &ldquo;antibiotic therapy&rdquo; and &ldquo;antibiotic treatment&rdquo; as research terms. Results. There is no universally accepted definition for ADE. Current evidence shows that ADE is a feasible strategy in the EGS setting, with the ability to optimize antibiotic use, to reduce hospitalization and health care costs, without compromising clinical outcome. Many studies focus on Intensive Care Unit patients, and a call for further studies is required in the EGS community. Current guidelines already recommend ADE when surgery for uncomplicated appendicitis and cholecystitis reaches a complete source control. Conclusions. ADE in an effective and feasible strategy in EGS patients, in order to optimize antibiotic management without compromising clinical outcomes. A collaborative effort between surgeons, intensivists and infectious disease specialists is mandatory. There is a strong need for further studies selectively focusing in the EGS ward setting
