    Abstract The conceptual underpinning of carcinogenesis has been strongly influenced by an expanded understanding of the human microbiome. Malignancy risks in diverse organs have been uniquely tied to aspects of the resident microbiota in different organs and systems including the colon, lungs, pancreas, ovaries, uterine cervix, and stomach; other organs are increasingly linked to maladaptive aspects of the microbiome as well. In this way, the maladaptive microbiome may be termed an oncobiome. Microbe-driven inflammation, anti-inflammation, and mucosal protection failure, as well as diet-induced microbiome derangement are all mechanisms that influence malignancy risk. Therefore, they also offer potential avenues of diagnostic and therapeutic intervention to modify malignancy risk, and to perhaps interrupt progression toward cancer in different sites. Each of these mechanisms will be explored using colorectal malignancy as a prototype condition to demonstrate the microbiome's role in carcinogenesis.

    Abstract Background: Infections after abdominal surgery remain a significant problem. Although preoperative antibiotic prophylaxis is a primary strategy used to reduce postoperative infections, it is typically prescribed based on standardized protocols, without attention to previous infection or antibiotic history. Patients with a previous infection after surgery may be at higher risk for infectious complications after subsequent operations owing to antibiotic resistance. We hypothesized that a previous postoperative infection is a significant risk factor for the development of infection after a second unrelated surgery.
    Study design: We performed a retrospective study of patients who had undergone 2 unrelated abdominal operations at a tertiary care center from 2012 to 2018. Clinical variables and microbiological culture results were abstracted. Univariate and multivariable regression models were constructed.
    Results: Of 758 patients, 15.0% (n = 114) developed an infection after the first operation. After the second operation, 22.8% (n = 26) of those with a previous infection developed another infection, whereas the incidence of an infection after the second operation was only 9.5% (n = 61) in patients who did not develop an infection after the first operation. Multivariable analysis demonstrated that previous infection (odds ratio 2.49, 95% CI 1.46 to 4.25) was associated with future infection risk. Microbiological analysis found that infections after the second surgery were significantly more likely to be antibiotic resistant than infections after the first surgery (82.3% vs 64.1%; p = 0.036). Strikingly, 49% of infections after the second surgery were resistant to the antibiotic prophylaxis given at the time of incision.
    Conclusions: Previous postoperative infection is an independent risk factor for a subsequent postoperative infection and is associated with resistance to standard prophylaxis. Individualization of antibiotic prophylaxis in patients with a previous postoperative infection is warranted.

    Abstract Background: Advances in the molecular biology of tumor metastasis have paralleled the evolution in the management of metastatic disease from colorectal cancer. In this review, we summarize the current understanding of the mechanism of colorectal cancer metastases, in particular that of peritoneal metastases, as well as clinical data on the treatment of this disease.
    Methods: A review of relevant English literature using MEDLINE/PubMed on the biology of colorectal cancer metastases, determinants of oligometastasis, and use of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of metastatic colorectal cancer is presented.
    Results: Recognition of oligometastasis in the evolution of colorectal peritoneal metastases provides the theoretical framework for which cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy is considered. Clearly, a subset of patients benefit from peritoneal metastasectomy.
    Conclusion: Advances in cancer biology and clinical imaging promise to expand the role of cytoreductive surgery with or without intraperitoneal chemotherapy in the management of peritoneal metastases from colorectal cancer.

    Abstract The extraordinary spread of the novel coronavirus (COVID-19) has dramatically and rapidly changed the way in which we provide medical care for patients with all diagnoses. Conservation of resources, social distancing, and the risk of poor outcomes in COVID-19-positive cancer patients have forced practitioners and surgeons to completely rethink routine care. The treatment of patients with rectal cancer requires both a multidisciplinary approach and a significant amount of resources. It is therefore imperative to rethink how rectal cancer treatment can be aligned with the current COVID-19 pandemic paradigms. In this review, we discuss evidence-based recommendations to optimize oncological outcomes during the COVID-19 pandemic.

    Abstract The microbiome exerts a remarkable effect on human physiology. The study of the human-microbiome relationship is a burgeoning field with great potential to improve our understanding of health and disease. In this review, we address common surgical problems influenced by the human microbiome and explore what is thus far known about this relationship. These include inflammatory bowel disease, colorectal neoplasms, and diverticular disease. We will also discuss the effect of the microbiome on surgical complications, specifically anastomotic leak. We hope that further research in this field will enlighten our management of these and other surgical problems.

    Abstract Background: In patients with ulcerative colitis who undergo IPAA, a diverting ileostomy is used to diminish the severity of anastomotic complications. Typically, the ileostomy is closed after an interval of 2 to 4 months. The safety of earlier closure of the ileostomy after pouch surgery is unknown.
    Objective: This study aimed to compare postoperative outcomes in patients randomly assigned to early (7-12 days) or late (≥8 weeks) ileostomy closure after ileal pouch construction.
    Design: This was a multicenter, prospective randomized trial.
    Setting: The study was conducted at colorectal surgical units at select United States hospitals.
    Patients: Adults with ulcerative colitis who underwent 2- or 3-stage proctocolectomy with IPAA were included.
    Main outcome measures: The primary outcomes included Comprehensive Complication Index at 30 days after ileostomy closure. The secondary outcomes included complications, severe complications, reoperations, and readmissions within 30 days of ileostomy closure.
    Results: The trial was stopped after interim analysis because of a high rate of complications after early ileostomy closure. Among 36 patients analyzed, 1 patient (3%) had unplanned proctectomy with end-ileostomy. Of the remaining 35 patients, 28 patients (80%) were clinically eligible for early closure and underwent radiologic assessment. There were 3 radiologic failures. Of the 25 remaining patients, 22 patients (88%) were randomly assigned to early closure (n = 10) or late closure (n = 12), and 3 patients were excluded. Median Comprehensive Complication Index was 14.8 (0-54) and 0 (0-23) after early and late closure (p = 0.02). One or more complications occurred in 7 patients (70%) after early closure and in 2 patients (17%) after late closure (p = 0.01)' and complications were severe in 3 patients (30%) after early closure and 0 patients after late closure (p = 0.04). Reoperation was required in 1 patient (10%) and 0 patients (p = 0.26) after early closure and readmission was required in 7 patients (70%) and 1 patient (8%) after late closure (p = 0.003).
    Limitations: This study was limited by early study closure and selection bias.
    Conclusions: Early closure of a diverting ileostomy in patients with ulcerative colitis who underwent IPAA is associated with an unacceptably high rate of complications. See Video Abstract at http://links.lww.com/DCR/C68.
    Alta tasa de complicaciones despus del cierre precoz de la ileostoma terminacin temprana del ensayo aleatorizado de intervalo corto versus largo para la reversin de la ileostoma en asa despus de la ciruga de reservorio ileal: ANTECEDENTES:En los pacientes con colitis ulcerosa que se someten a una anastomosis del reservorio ileoanal, se utiliza una ileostomía de derivación para disminuir la gravedad de las complicaciones de la anastomosis. Por lo general, la ileostomía se cierra después de un intervalo de 2 a 4 meses. Se desconoce la seguridad del cierre más temprano de la ileostomía después de la cirugía de reservorio.OBJETIVO:Comparar los resultados posoperatorios en pacientes asignados al azar al cierre temprano (7-12 días) o tardío (≥ 8 semanas) de la ileostomía después de la construcción de un reservorio ileal.DISEÑO:Este fue un ensayo aleatorizado prospectivo multicéntrico.ESCENARIO:El estudio se realizó en unidades quirúrgicas colorrectales en hospitales seleccionados de los Estados Unidos.PACIENTES:Se incluyeron adultos con colitis ulcerosa que se sometieron a proctocolectomía en 2 o 3 tiempos con anastomosis ileoanal con reservorio.PRINCIPALES MEDIDAS DE RESULTADO:Los resultados primarios incluyeron el Índice Integral de Complicaciones a los 30 días después del cierre de la ileostomía. Los resultados secundarios incluyeron complicaciones, complicaciones graves, reoperaciones y readmisiones dentro de los 30 días posteriores al cierre de la ileostomía.RESULTADOS:El ensayo se detuvo después del análisis interino debido a una alta tasa de complicaciones después del cierre temprano de la ileostomía. Entre los 36 pacientes analizados, 1 (3%) tuvo una proctectomía no planificada con ileostomía terminal. De los 35 pacientes restantes, 28 (80%) fueron clínicamente elegibles para el cierre temprano y se sometieron a una evaluación radiológica. Hubo 3 fracasos radiológicos. De los 25 pacientes restantes, 22 (88 %) se asignaron al azar a cierre temprano (n = 10) o tardío (n = 12) y 3 fueron excluidos. La mediana del Índice Integral de Complicaciones fue de 14,8 (0-54) y 0 (0-23) después del cierre temprano y tardío (p = 0,02). Una o más complicaciones ocurrieron en 7 pacientes (70%) después del cierre temprano y 2 (17%) pacientes después del cierre tardío (p = 0,01) y fueron graves en 3 (30%) y 0 pacientes, respectivamente (p = 0,04). Requirieron reintervención en 1 (10%) y 0 (p = 0,26) y reingreso en 7 (70%) y 1 (8%) pacientes (p = 0,003).LIMITACIONES:Este estudio estuvo limitado por el cierre temprano del estudio; sesgo de selección.CONCLUSIONES:El cierre temprano de una ileostomía de derivación en pacientes con colitis ulcerosa con anastomosis de reservorio ileoanal se asocia con una tasa inaceptablemente alta de complicaciones.
