Diverticulitis with abscess formation: Outcomes of non-operative management and nomogram for predicting emergency surgery: The Diplicab Study Collaborative Group.

BACKGROUND: To assess short- and long-term outcomes from non-surgical management of diverticulitis with abscess formation and to develop a nomogram to predict emergency surgery. METHODS: This nationwide retrospective cohort study was performed in 29 Spanish referral centers, including patients with a first episode of a diverticular abscess (modified Hinchey Ib-II) from 2015 to 2019. Emergency surgery, complications, and recurrent episodes were analyzed. Regression analysis was used to assess risk factors, and a nomogram for emergency surgery was designed. RESULTS: Overall, 1,395 patients were included (1,078 Hinchey Ib and 317 Hinchey II). Most (1,184, 84.9%) patients were treated with antibiotics without percutaneous drainage, and 194 (13.90%) patients required emergency surgery during admission. Percutaneous drainage (208 patients) was associated with a lower risk of emergency surgery in patients with abscesses of ≥5 cm (19.9% vs 29.3%, P = .035; odds ratio 0.59 [0.37-0.96]). The multivariate analysis showed that immunosuppression treatment, C-reactive protein (odds ratio: 1.003; 1.001-1.005), free pneumoperitoneum (odds ratio: 3.01; 2.04-4.44), Hinchey II (odds ratio: 2.15; 1.42-3.26), abscess size 3 to 4.9 cm (odds ratio: 1.87; 1.06-3.29), abscess size ≥5 cm (odds ratio: 3.62; 2.08-6.32), and use of morphine (odds ratio: 3.68; 2.29-5.92) were associated with emergency surgery. A nomogram was developed with an area under the receiver operating characteristic curve of 0.81 (95% confidence interval: 0.77-0.85). CONCLUSION: Percutaneous drainage must be considered in abscesses ≥5 cm to reduce emergency surgery rates; however, there are insufficient data to recommend it in smaller abscesses. The use of the nomogram could help the surgeon develop a targeted approach.

The economic impact of anastomotic leak after colorectal cancer surgery.

OBJECTIVE: To determine the economic impact of the incremental consumption of resources for the diagnosis and treatment of anastomotic leak (AL) in patients after resection with anastomosis for colorectal cancer compared to patients without AL on the Spanish health system. METHOD: This study included a literature review with parameters validated by experts and the development of a cost analysis model to estimate the incremental resource consumption of patients with AL versus those without. The patients were divided into three groups: 1) colon cancer (CC) with resection, anastomosis and AL; 2) rectal cancer (RC) with resection, anastomosis without protective stoma and AL; and 3) RC with resection, anastomosis with protective stoma and AL. RESULTS: The average total incremental cost per patient was €38,819 and €32,599 for CC and RC, respectively. The cost of AL diagnosis per patient was €1018 (CC) and €1030 (RC). The cost of AL treatment per patient in Group 1 ranged from €13,753 (type B) to €44,985 (type C + stoma), that in Group 2 ranged from €7348 (type A) to €44,398 (type C + stoma), and that in Group 3 ranged from €6197 (type A) to €34,414 (type C). Hospital stays represented the highest cost for all groups. In RC, protective stoma was found to minimize the economic consequences of AL. CONCLUSIONS: The appearance of AL generates a considerable increase in the consumption of health resources, mainly due to an increase in hospital stays. The more complex the AL, the higher the cost associated with its treatment. INTEREST OF THE STUDY: it is the first cost-analysis study of AL after CR surgery based on prospective, observational and multicenter studies, with a clear, accepted and uniform definition of AL and estimated over a period of 30 days.

Diagnostic accuracy of C-reactive protein, procalcitonin and neutrophils for the early detection of anastomotic leakage after colorectal resection: a multicentric, prospective study.

AIM: The aim was to determine the accuracy of C-reactive protein (CRP), procalcitonin and neutrophils in the early detection (fourth postoperative day) of anastomotic leakage (AL) after colorectal surgery. METHODS: We conducted a multicentre, prospective study that included a consecutive series of patients who underwent colorectal resection with anastomosis without ostomy (September 2015 to December 2017). CRP, procalcitonin and neutrophil values on the fourth postoperative day after colorectal resection along with the postoperative outcome (60-day AL, morbidity and mortality) were prospectively included in an online, anonymous database. RESULTS: The analysis ultimately included 2501 cases. The overall morbidity and mortality was 30.1% and 1.6%, respectively, and the AL rate was 8.6%. The area under the receiver operating characteristic curve values (95% CI) for detecting AL were 0.84 (0.81-0.87), 0.75 (0.72-0.79) and 0.70 (0.66-0.74) for CRP, procalcitonin and neutrophils, respectively. The best cut-off level for CRP was 119 mg/l, resulting in 70% sensitivity, 81% specificity and 97% negative predictive value. After laparoscopic resection, the accuracy for CRP and procalcitonin was increased, compared with open resection. The combination of two or three of these biomarkers did not significantly increase their accuracy. CONCLUSION: On the fourth postoperative day, CRP was the most reliable marker for excluding AL. Its high negative predictive value, especially after laparoscopic resection, allows for safe hospital discharge on the fourth postoperative day. The routine use of procalcitonin or neutrophil counts does not seem to increase the diagnostic accuracy.

Preoperative oral antibiotics and surgical-site infections in colon surgery (ORALEV): a multicentre, single-blind, pragmatic, randomised controlled trial.

BACKGROUND: Previous studies have found that mechanical bowel preparation with oral antibiotics can reduce the incidence of surgical-site infections, but no randomised controlled trial has assessed oral antibiotics alone without mechanical bowel preparation. The aim of this study was to determine whether prophylaxis with oral antibiotics the day before elective colon surgery affects the incidence of postoperative surgical-site infections. METHODS: In this multicentre, pragmatic, randomised controlled trial (ORALEV), patients undergoing colon surgery were recruited from five major hospitals in Spain and 47 colorectal surgeons at these hospitals participated. Patients were eligible for inclusion if they were diagnosed with neoplasia or diverticular disease and if a partial colon resection or total colectomy was indicated. Participants were randomly assigned (1:1) using online randomisation tables to either administration of oral antibiotics the day before surgery (experimental group) or no administration of oral antibiotics before surgery (control group). For the experimental group, ciprofloxacin 750 mg was given every 12 h (two doses at 1200 h and 0000 h) and metronidazole 250 mg every 8 h (three doses at 1200 h, 1800 h, and 0000 h) the day before surgery. All patients were given intravenous cefuroxime 1·5 g and metronidazole 1 g at the time of anaesthetic induction. The primary outcome was incidence of surgical-site infections. Patients were followed up for 1 month after surgery and all postsurgical complications were registered. This study was registered with EudraCT, 2014-002345-21, and ClinicalTrials.gov, NCT02505581, and is closed to accrual. FINDINGS: Between May 2, 2015, and April 15, 2017, we assessed 582 patients for eligibility, of whom 565 were eligible and randomly assigned to receive either no oral antibiotics (n=282) or oral antibiotics (n=282) before surgery. 13 participants in the control group and 16 in the experimental group were subsequently excluded; 269 participants in the control group and 267 in the experimental group received their assigned intervention. The incidence of surgical-site infections in the control group (30 [11%] of 269) was significantly higher than in the experimental group (13 [5%] of 267; χ2 test p=0·013). Oral antibiotics were associated with a significant reduction in the risk of surgical-site infections compared with no oral antibiotics (odds ratio 0·41, 95% CI 0·20-0·80; p=0·008). More complications (including surgical-site infections) were observed in the control group than in the experimental group (76 [28%] vs 51 [19%]; p=0·017), although there was no difference in severity as assessed by Clavien-Dindo score. No differences were noted between groups in terms of local complications, surgical complications, or medical complications that were not related to septic complications. INTERPRETATION: The administration of oral antibiotics as prophylaxis the day before colon surgery significantly reduces the incidence of surgical-site infections without mechanical bowel preparation and should be routinely adopted before elective colon surgery.

Controversias en el tratamiento de la hernia de Amyand / Controversies in the treatment of Amyand´s hernia

La hernia de Amyand tiene baja incidencia (0,1 a 1 %) pero, en caso de complicación, puede asociarse con una alta tasa de mortalidad. A pesar de haber sido descrita hace más de 200 años por Claudius Amyand, siguen existiendo ciertas controversias sobre su correcto tratamiento en determinadas situaciones. La práctica o la evitación de la apendicectomía en ausencia de apendicitis y la técnica para reparar el defecto herniario según el grado de contaminación de la zona, son temas tratados en el presente artículo. Ante la falta de consenso global en la literatura científica, la individualización de cada caso y el buen juicio del cirujano deben primar a la hora de decidir el tratamiento más adecuado. Se presentan dos casos clínicos que, a pesar de tratarse de la misma enfermedad, tuvieron formas de presentación, manejo y evolución dispares. Asimismo, se adjunta la iconografía de un excepcional caso de hernia de Amyand, izquierda, junto con el hallazgo de una hernia de Littré no complicada en el mismo saco herniario

Amyand's hernia has a low incidence (0.1%-1.0%) but it may be associated with high mortality rates. Despite having been described more than 200 years ago by Claudius Amyand, there are still controversies regarding treatment in some particular situations. Performing or not appendectomies in the absence of appendicitis, or how to perform the hernia repair depending on the degree of contamination, are topics discussed in this article. There is not a global consensus in the literature yet. The individualization of each case and the surgeon´s proper judgment should be the priority for selecting the most appropriate treatment. Two clinical cases of Amyand's hernia are reported with very different clinical presentations, management and evolution. Also, an image of a left sided Amyand's hernia together with a Littre's hernia in the same hernia sac is shown

Very Late Reactivation of Retinopathy of Prematurity After Monotherapy With Intravitreal Bevacizumab.

The authors report a case of very late reactivation of retinopathy of prematurity (ROP) after bevacizumab monotherapy. A female born at 630 g and 24 weeks received two bilateral treatment of bevacizumab (Avastin; Genentech, South San Francisco, CA) for aggressive posterior ROP (APROP). At 2.5 years of age, ROP reactivated in the form of tractional retinal detachment in one eye and milder reactivation in the other. Although intravitreal bevacizumab treatment is effective in inducing regression of ROP, late reactivation and retinal detachments can occur after initial extended quiescence. Due to alterations of disease progression after bevacizumab, close follow-up by peripheral fluorescein angiography and laser ablation of persistent avascular retina is recommended to prevent disease reactivation and progression to retinal detachment.

[Surgical treatment of adrenal gland metastases: results in a series of 35 patients]. / Cirugía de las metástasis en la glándula suprarrenal: resultados de una serie de 35 pacientes.

INTRODUCTION: The objectives of this study are to present the results of adrenalectomies due to metastasis, and to analyse the prognostic factors that may help to predict long-term survival in this patient group. PATIENTS AND METHODS: A retrospective study was conducted on 35 patients who underwent adrenalectomy for metastases in the Hospital de Cruces from 1996 to January 2010. The survival analysis was performed using the Kaplan and Meier method. RESULTS: Non-small cell lung cancer (NSCLC) was the most frequent primary tumour, with 18 cases. In 15 patients the diagnosis of adrenal metastasis was synchronous with the primary tumour, and in 20 cases it was metachronous. Only 7 patients survived without disease for 12, 22, 26, 58, 60, 65 and 120 months after the adrenalectomy. The disease free survival at 5 years was 16% in the whole series, and 27% in the NSCLC sub-group. None of the prognostic factors evaluated (size greater than 4.5 cm, cell type, differentiation grade, chemotherapy, surgical technique, disease free interval) was statistically significant in the overall survival, either in the general series or in the sub-group of patients with NSCLC. However, in the general series with tumour recurrence, the difference in survival between metachronous and synchronous metastasis was statistically significant (P=.05), in favour of the former. CONCLUSIONS: Adrenalectomy improves the expected survival particularly in patients with NSCLC. Patients with metachronous metastases do not have a higher rate of disease free survival at 5 years than those with synchronous metastases, although they do have a longer survival with the disease. When there is tumour recurrence, it is usually early.
