The role of RObotic surgery in EMergency setting (ROEM): protocol for a multicentre, observational, prospective international study on the use of robotic platform in emergency surgery.

BACKGROUND: Robotic surgery has gained widespread acceptance in elective interventions, yet its role in emergency procedures remains underexplored. While the 2021 WSES position paper discussed limited studies on the application of robotics in emergency general surgery, it recommended strict patient selection, adequate training, and improved platform accessibility. This prospective study aims to define the role of robotic surgery in emergency settings, evaluating intraoperative and postoperative outcomes and assessing its feasibility and safety. METHODS: The ROEM study is an observational, prospective, multicentre, international analysis of clinically stable adult patients undergoing robotic surgery for emergency treatment of acute pathologies including diverticulitis, cholecystitis, and obstructed hernias. Data collection includes patient demographics and intervention details. Furthermore, data relating to the operating theatre team and the surgical instruments used will be collected in order to conduct a cost analysis. The study plans to enrol at least 500 patients from 50 participating centres, with each centre having a local lead and collaborators. All data will be collected and stored online through a secure server running the Research Electronic Data Capture (REDCap) web application. Ethical considerations and data governance will be paramount, requiring local ethical committee approvals from participating centres. DISCUSSION: Current literature and expert consensus suggest the feasibility of robotic surgery in emergencies with proper support. However, challenges include staff training, scheduling conflicts with elective surgeries, and increased costs. The ROEM study seeks to contribute valuable data on the safety, feasibility, and cost-effectiveness of robotic surgery in emergency settings, focusing on specific pathologies. Previous studies on cholecystitis, abdominal hernias, and diverticulitis provide insights into the benefits and challenges of robotic approaches. It is necessary to identify patient populations that benefit most from robotic emergency surgery to optimize outcomes and justify costs.

Intra-abdominal infections survival guide: a position statement by the Global Alliance For Infections In Surgery.

Intra-abdominal infections (IAIs) are an important cause of morbidity and mortality in hospital settings worldwide. The cornerstones of IAI management include rapid, accurate diagnostics; timely, adequate source control; appropriate, short-duration antimicrobial therapy administered according to the principles of pharmacokinetics/pharmacodynamics and antimicrobial stewardship; and hemodynamic and organ functional support with intravenous fluid and adjunctive vasopressor agents for critical illness (sepsis/organ dysfunction or septic shock after correction of hypovolemia). In patients with IAIs, a personalized approach is crucial to optimize outcomes and should be based on multiple aspects that require careful clinical assessment. The anatomic extent of infection, the presumed pathogens involved and risk factors for antimicrobial resistance, the origin and extent of the infection, the patient's clinical condition, and the host's immune status should be assessed continuously to optimize the management of patients with complicated IAIs.

Usefulness of Fluorescence imaging with indocyanine green for evaluation of bowel perfusion in the urgency setting: a systematic review and meta-analysis.

INTRODUCTION: Fluorescence imaging with indocyanine (ICG) has been extensively utilized to assess bowel perfusion in oncologic surgery. In the emergency setting there are many situations in which bowel perfusion assessment is required. Large prospective studies or RCTs evaluating feasibility, safety and utility of ICG in the emergency setting are lacking. The primary aim is to assess the usefulness of ICG for evaluation of bowel perfusion in the emergency setting. MATERIALS AND METHODS: The manuscript was drafted following the recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA). A systematic literature search was carried out through Pubmed, Scopus, and the ISI Web of Science. Assessment of included study using the methodological index for non-randomized studies (MINORS) was calculated. The meta-analysis was carried out in line with recommendations from the Cochrane Collaboration and Meta-analysis of Observational Studies in Epidemiology guidelines, and the Mantel-Haenszel random effects model was used to calculate effect sizes. RESULTS: 10,093 papers were identified. 84 were reviewed in full-text, and 78 were excluded: 64 were case reports; 10 were reviews without original data; 2 were letters to the editor; and 2 contained unextractable data. Finally, six studies22-27 were available for quality assessment and quantitative synthesis. The probability of reoperation using ICG fluorescence angiography resulted similar to the traditional assessment of bowel perfusion with a RD was -0.04 (95% CI:-0.147 to 0.060). The results were statistically significant P=0.029, although the heterogeneity was not negligible with a 59.9% of the I2 index. No small study effect or publication bias were found. CONCLUSIONS: This first metanalysis on the use of IGC fluorescence for ischemic bowel disease showed that this methodology is a safe and feasible tool in the assessment of bowel perfusion in the emergency setting. This topic should be further investigated in high quality studies.

Prophylaxis and treatment of peritoneal carcinomatosis of gastric origin using hyperthermic intraperitoneal chemotherapy: a systematic review and meta-analysis of randomized trials.

BACKGROUND: Peritoneal carcinomatosis significantly worsens the prognosis of patients with gastric cancer. Cytoreduction + hyperthermic intraperitoneal chemotherapy (HIPEC) has shown promising results in the prevention and treatment of peritoneal carcinomatosis in advanced gastric cancer (AGC); however, its application remains controversial owing to the variability of the approaches used to perform it and the lack of high-quality evidence. This systematic review and meta-analysis aimed to investigate the role of surgery and HIPEC in the prevention and treatment of peritoneal carcinomatosis of gastric origin. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials comparing surgery + HIPEC vs surgery + chemotherapy for the prophylaxis of peritoneal carcinomatosis and cytoreduction + HIPEC vs chemotherapy or other palliative options for the treatment of peritoneal carcinomatosis. RESULTS: Sixteen studies enrolling 1641 patients were included. Surgery + HIPEC significantly improved overall survival in both prophylactic (hazard ratio [HR], 0.56) and therapeutic (HR, 0.57) settings. When surgery + HIPEC was performed with prophylactic intent, the pooled 3-year mortality rate was 32%, whereas for the control group it was 55%. The overall and peritoneal recurrence rates were also reduced (risk ratio [RR], 0.59 and 0.40, respectively). No significant difference was found in morbidity between groups (RR, 0.92). CONCLUSION: Based on the current knowledge, HIPEC in AGC seems to be a safe and effective tool for prophylaxis and a promising resource for the treatment of peritoneal carcinomatosis. Regarding the treatment of peritoneal carcinomatosis, the scarcity of large-cohort studies and the heterogeneity of the techniques adopted prevented us from achieving a definitive recommendation.

Bedside Laparoscopy in the Critically Ill: A Review of the Literature.

Critically ill patients treated in the intensive care unit (ICU) can present with many abdominal conditions that need a prompt diagnosis and timely treatment because of their general frailty. Clinical evaluation and diagnostic tools like ultrasound or CT scans are not reliable or feasible in these patients. Bedside laparoscopy (BSL) is a minimally invasive procedure that allows surgeons to assess the abdominal cavity directly in the ICU, thus avoiding unnecessary exploratory laparotomy or incidents related to intra-hospital transfer. We conducted a review of the literature to summarize the state-of-the-art of BSL. The Medline, Cochrane Central Register of Controlled Trials (CENTRAL), and Scopus databases were utilized to identify all relevant publications. Indications, contraindications, technical aspects, and outcomes are discussed. The procedure is safe, feasible, and effective. When other diagnostic tools fail to diagnose or exclude an intra-abdominal condition in ICU patients, BSL should be preferred over exploratory laparotomy.

Are Surgeons Going to Be Left Holding the Bag? Incisional Hernia Repair and Intra-Peritoneal Non-Absorbable Mesh Implant Complications.

Ventral incisional hernias are common indications for elective repair and frequently complicated by recurrence. Surgical meshes, which may be synthetic, bio-synthetic, or biological, decrease recurrence and, resultingly, their use has become standard. While most patients are greatly benefited, mesh represents a permanently implanted foreign body. Mesh may be implanted within the intra-peritoneal, preperitoneal, retrorectus, inlay, or onlay anatomic positions. Meshes may be associated with complications that may be early or late and range from minor to severe. Long-term complications with intra-peritoneal synthetic mesh (IPSM) in apposition to the viscera are particularly at risk for adhesions and potential enteric fistula formation. The overall rate of such complications is difficult to appreciate due to poor long-term follow-up data, although it behooves surgeons to understand these risks as they are the ones who implant these devices. All surgeons need to be aware that meshes are commercial devices that are delivered into their operating room without scientific evidence of efficacy or even safety due to the unique regulatory practices that distinguish medical devices from medications. Thus, surgeons must continue to advocate for more stringent oversight and improved scientific evaluation to serve our patients properly and protect the patient-surgeon relationship as the only rationale long-term strategy to avoid ongoing complications.

Cesena guidelines: WSES consensus statement on laparoscopic-first approach to general surgery emergencies and abdominal trauma.

BACKGROUND: Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma. METHODS: This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement. RESULTS: A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma. CONCLUSIONS: The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

Management of Intra-Abdominal Infections: The Role of Procalcitonin.

Patients with intra-abdominal sepsis suffer from significant mortality and morbidity. The main pillars of treatment for intra-abdominal infections are (1) source control and (2) early delivery of antibiotics. Antibiotic therapy should be started as soon as possible. However, the duration of antibiotics remains a matter of debate. Prolonged antibiotic delivery can lead to increased microbial resistance and the development of nosocomial infections. There has been much research on biomarkers and their ability to aid the decision on when to stop antibiotics. Some of these biomarkers include interleukins, C-reactive protein (CRP) and procalcitonin (PCT). PCT's value as a biomarker has been a focus area of research in recent years. Most studies use either a cut-off value of 0.50 ng/mL or an >80% reduction in PCT levels to determine when to stop antibiotics. This paper performs a literature review and provides a synthesized up-to-date global overview on the value of PCT in managing intra-abdominal infections.

Should we exclude patients with peritoneal carcinosis of colorectal origin and high PCI from CRS + HIPEC?

International guidelines exclude from surgery patients with peritoneal carcinosis of colorectal origin and a peritoneal cancer index (PCI) ≥ 16. This study aims to analyze the outcomes of patients with colorectal peritoneal carcinosis and PCI greater or equal to 16 treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) (CRS + HIPEC). We retrospectively performed a multicenter observational study involving three Italian institutions, namely the IRCCS Policlinico San Matteo in Pavia, the M. Bufalini Hospital in Cesena, and the ASST Papa Giovanni XXIII Hospital in Bergamo. The study included all patients undergoing CRS + HIPEC for peritoneal carcinosis from colorectal origin from November 2011 to June 2022. The study included 71 patients: 56 with PCI < 16 and 15 with PCI ≥ 16. Patients with higher PCI had longer operative times and a statistically significant higher rate of not complete cytoreduction, with a Completeness of Cytoreduction score (CC) 1 (microscopical disease) of 30.8% (p = 0.004). The 2-year OS was 81% for PCI < 16 and 37% for PCI ≥ 16 (p < 0.001). The 2-years DFS was 29% for PCI < 16 and 0% for PCI ≥ 16 (p < 0.001). The 2-year peritoneal DFS for patients with PCI < 16 was 48%, and for patients with PCI ≥ 16 was 57% (p = 0.783). CRS and HIPEC provide reasonable local disease control for patients with carcinosis of colorectal origin and PCI ≥ 16. Such results form the basis for new studies to reassess the exclusion of these patients, as set out in the current guidelines, from CRS and HIPEC. This therapy, combined with new therapeutical strategies, i.e., pressurized intraperitoneal aerosol chemotherapy (PIPAC), could offer reasonable local control of the disease, preventing local complications. As a result, it increases the patient's chances of receiving chemotherapy to improve the systemic control of the disease.

Management of complicated diaphragmatic hernia in the acute setting: a WSES position paper.

BACKGROUND: Diaphragmatic hernia (DH) presenting acutely can be a potentially life-threatening condition. Its management continues to be debatable. METHODS: A bibliographic search using major databases was performed using the terms "emergency surgery" "diaphragmatic hernia," "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia." GRADE methodology was used to evaluate the evidence and give recommendations. RESULTS: CT scan of the chest and abdomen is the diagnostic gold standard to evaluate complicated DH. Appropriate preoperative assessment and prompt surgical intervention are important for a clinical success. Complicated DH repair is best performed via the use of biological and bioabsorbable meshes which have proven to reduce recurrence. The laparoscopic approach is the preferred technique in hemodynamically stable patients without significant comorbidities because it facilitates early diagnosis of small diaphragmatic injuries from traumatic wounds in the thoraco-abdominal area and reduces postoperative complications. Open surgery should be reserved for situations when skills and equipment for laparoscopy are not available, where exploratory laparotomy is needed, or if the patient is hemodynamically unstable. Damage Control Surgery is an option in the management of critical and unstable patients. CONCLUSIONS: Complicated diaphragmatic hernia is a rare life-threatening condition. CT scan of the chest and abdomen is the gold standard for diagnosing the diaphragmatic hernia. Laparoscopic repair is the best treatment option for stable patients with complicated diaphragmatic hernias. Open repair is considered necessary in majority of unstable patients in whom Damage Control Surgery can be life-saving.

Acute left colonic diverticulitis in the emergency setting: from diagnosis to treatment.

Acute left colonic diverticulitis (ALCD) is a common clinical condition encountered by physicians in the emergency setting. Clinical presentation of ALCD ranges from uncomplicated acute diverticulitis to diffuse fecal peritonitis. ALCD may be diagnosed based on clinical features alone, but imaging is necessary to differentiate uncomplicated from complicated forms. In fact, computed tomography scan of the abdomen and pelvis is the highest accurate radiological examination for diagnosing ALCD. Treatment depends on the clinical picture, the severity of patient's clinical condition and underlying comorbidities. Over the last few years, diagnosis and treatment algorithms have been debated and are currently evolving. The aim of this narrative review was to consider the main aspects of diagnosis and treatment of ALCD.

Biliary Sepsis Due to Recurrent Acute Calculus Cholecystitis (ACC) in a High Surgical-Risk Elderly Patient: An Unexpected Complication.

Acute calculus cholecystitis (ACC) is increasing in frequency within an ageing population, in which biliary tract infection, including cholecystitis and cholangitis, is the second most common cause of sepsis, with higher morbidity and mortality rates. Patient's critical conditions, such as septic shock or anaesthesiology contraindication, may be reasons to avoid laparoscopic cholecystectomy-the first-line treatment of ACC-preferring gallbladder drainage. It can aid in patient's stabilization with also the benefit of identifying the causative organism to establish a targeted antibiotic therapy, especially in patients at high risk for antimicrobial resistance such as healthcare-associated infection. Nevertheless, a recent randomized clinical trial showed that laparoscopic cholecystectomy can reduce the rate of major complications compared with percutaneous catheter drainage in critically ill patients too. On the other hand, among the possibilities to control biliary sepsis in non-operative management of ACC, according to recent meta-analysis, endoscopic gallbladder drainage showed better clinical success rate, and it is gaining popularity because of the potential advantage of allowing gallstones clearance to reduce recurrences of ACC. However, complications that may arise, although rare, can worsen an already weak clinical condition, as happened to the high surgical-risk elderly patient taken into account in our case report.

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 "sepsis" AND "intra-abdominal infections" AND ("antibiotic therapy" OR "antibiotic treatment"). 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'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.

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 "de-escalation", "antibiotic therapy" and "antibiotic treatment" 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.

Intracorporeal anastomosis versus extracorporeal anastomosis after laparoscopic right hemicolectomy for colon cancer: morbidity comparison at long-term follow-up.

BACKGROUND: Minimally invasive right hemicolectomy is nowadays considered the gold standard for treatment of malignant right colon disease. What is still debated is instead the choice between intracorporeal or extracorporeal anastomosis. The aim of this study was to compare morbidity and the long-term results between these two techniques. METHODS: This retrospective, double-center cohort study was performed between January 2013 and December 2014. A total of 197 patients were enrolled after laparoscopic right hemicolectomy for malignant disease. The extracorporeal anastomosis group (ECA) included 95 patients, while the intracorporeal anastomosis group (ICA) included 102 patients. All patients were followed up for 5 years after surgery. Data analysis was performed in February 2021. RESULTS: The ICA group showed a reduced rate of non-surgical complications Clavien-Dindo grade I-II (10% vs. 31%; P=0.001) as well as a lower rate of wound infections (2% vs. 12%; P=0.01). Most importantly, a decreased risk of incisional hernias in a five-year follow-up period (1% vs. 8%; P=0.01) has been underlined. CONCLUSIONS: Intracorporeal anastomosis technique after totally laparoscopic right hemicolectomy showed better outcomes as it significantly reduces the risk for short and long-term complications, namely, incisional hernias.

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.

Intraoperative endoscopy with immediate suture reinforcement of the defect in colorectal anastomosis: a pilot study.

Colorectal anastomosis is the one at higher risk of complication in alimentary tract surgery. Several techniques have been used to intraoperatively check a colorectal anastomosis, without reaching a clear consensus. The aim of the present study is to evaluate the addition of intraoperative flexible endoscopy to indocyanine green fluorescence in detecting colorectal anastomotic defects in a consecutive series of patients. This was a pilot study conducted over a 15-month period. Patients were scheduled for an elective laparoscopic left colectomy or anterior resection with a planned stapled colorectal anastomosis. Pre-, intra- and postoperative data were collected. Intraoperative endoscopy was routinely performed and the anastomotic defects were classified. A suture reinforcement of the defect encountered was immediately performed either laparoscopically or transanally. The primary endpoint of the study was the rate of postoperative complications. Fitfty-two patients were enrolled. At intraoperative endoscopy, 12 anastomotic defects were detected and corrected with immediate suture reinforcement. Defects were classified as two leaks, two mucosal crash, one simultaneous leak and crash, one mucosal edema and six active bleedings. None of these patients developed any postoperative complication. Moreover, there was no postoperative bleeding complication in the entire cohort. The three patients developing a postoperative leak requiring anastomosis takedown were at high risk due to general status and cancer characteristics. Even though more data and a comparative group are needed, the results of this pilot study are very promising regarding the role of intraoperative endoscopy and suture reinforcement of a colorectal anastomotic defect.

Morbidity associated with closure of ileostomy after a three-stage ileal pouch-anal anastomosis.

The aim of the study was to compare the perioperative outcomes of patients undergoing ileostomy closure after a three-stage ileal pouch-anal anastomosis to a control group of patients who had elective colorectal resections and stoma, and to analyse the differences based on the technique of closure. The cases were retrospectively compared for demographic characteristics and postoperative outcomes. Chi-square, Fisher's exact and Wilcoxon rank sum tests were used as appropriate. Between 2011 and 2016, 338 patients having their stoma reversed after three-stage IPAA were compared to 158 patients in the control group. A younger age (43.2 vs 60.6 years, p < 0.0001), a lower body mass index (22 vs 24.4 kg/m2, p < 0.0001), a higher rate of hand-sewn anastomosis (84.3 vs 15.7%, p < 0.0001), a lower rate of intraoperative complications (0 vs 1.2%, p = 0.038), a shorter operative time (91.5 vs 99.4 min, p = 0.0046) and length of hospital stay (6.6 vs 7.6 days, p = 0.045) were seen in the IPAA group. The 30-day rate of wound infection, anastomotic leak (0.6 vs 0.6%), small bowel obstruction (SBO, 8 vs 11.4%) and reoperation (1.8 vs 1.3%) was similar. Among IPAA patients, the hand-sewn anastomosis was correlated with a higher chance of developing SBO (9.1 vs 1.9%, p = 0.03). Closure of ileostomy after three-stage IPAA is associated with low rate of serious complications, despite the higher number of previous abdominal surgeries. This supports the construction of routine ileostomy during IPAA to reduce the risk of pelvic sepsis.

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 (0.7-12.6). At the multivariate linear regression, early relapse was significantly associated with use of biologics before primary surgery (-2.69, p < 0.0001) and location of disease in the ileum (-1.61, 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.

Biological therapy for the treatment of prepouch ileitis: a retrospective observational study from three centers.

AIM: Prepouch ileitis (PPI) is inflammation of the ileum proximal to an ileoanal pouch, usually associated with pouchitis. The treatment of PPI as a specific entity has been poorly studied, but it is generally treated concurrently with pouchitis. This to our knowledge is the largest study to explore the efficacy of biologics for the specific treatment of PPI. METHODS: This was a retrospective observational study reporting outcomes following biological treatment in patients with PPI across three centers. Data were collected between January 2004 and February 2018 from two centers in the UK and one center in Italy. Outcomes included the continued presence of PPI following biologic therapy, pouch failure defined by the need for an ileostomy, and remission of PPI defined by the absence of any prepouch inflammation on endoscopic assessment within a year of biologic therapy. RESULTS: There were 29 patients in our cohort. On last endoscopic follow-up, 20/29 still had endoscopic evidence of PPI, seven had achieved endoscopic remission and avoided an ileostomy, and two had no endoscopic follow-up. In our cohort 11 patients had an ileostomy after a median time from starting a biologic of 25 months (range 14-91). CONCLUSION: Biologics fail to induce endoscopic remission of PPI in the majority of patients. Just under one-third patients with PPI coexistent with pouchitis can achieve endoscopic remission with biologics. In a large proportion of patients with PPI, surgery may be required despite biologic use.
