Oral antibiotic prophylaxis lowers surgical site infection in elective colorectal surgery: results of a pragmatic cohort study in Catalonia

Background: The role of oral antibiotic prophylaxis (OAP) and mechanical bowel preparation (MBP) in the prevention of surgical site infection (SSI) after colorectal surgery is still controversial. The aim of this study was to analyze the effect of a bundle including both measures in a National Infection Surveillance Network in Catalonia. Methods: Pragmatic cohort study to assess the effect of OAP and MBP in reducing SSI rate in 65 hospitals, comparing baseline phase (BP: 2007-2015) with implementation phase (IP: 2016-2019). To compare the results, a logistic regression model was established. Results: Out of 34,421 colorectal operations, 5180 had SSIs (15.05%). Overall SSI rate decreased from 18.81% to 11.10% in BP and IP, respectively (OR 0.539, CI95 0.507-0.573, p < 0.0001). Information about bundle implementation was complete in 61.7% of cases. In a univariate analysis, OAP and MBP were independent factors in decreasing overall SSI, with OR 0.555, CI95 0.483-0.638, and OR 0.686, CI95 0.589-0.798, respectively; and similarly, organ/space SSI (O/S-SSI) (OR 0.592, CI95 0.494-0.710, and OR 0.771, CI95 0.630-0.944, respectively). However, only OAP retained its protective effect at both levels at multivariate analyses. Conclusions: oral antibiotic prophylaxis decreased the rates of SSI and O/S-SSI in a large series of elective colorectal surger

Laparoscopic colorectal surgery: current status and implementation of the latest technological innovations.

The introduction of laparoscopy is an example of surgical innovation with a rapid implementation in many areas of surgery. A large number of controlled studies and meta-analyses have shown that laparoscopic colorectal surgery is associated with the same benefits than other minimally invasive procedures, including lesser pain, earlier recovery of bowel transit and shorter hospital stay. On the other hand, despite initial concerns about oncological safety, well-designed prospective randomized multicentre trials have demonstrated that oncological outcomes of laparoscopy and open surgery are similar. Although the use of laparoscopy in colorectal surgery has increased in recent years, the percentages of patients treated with surgery using minimally invasive techniques are still reduced and there are also substantial differences among centres. It has been argued that the limiting factor for the use of laparoscopic procedures is the number of surgeons with adequate skills to perform a laparoscopic colectomy rather than the tumour of patients' characteristics. In this regard, future efforts to increase the use of laparoscopic techniques in colorectal surgery will necessarily require more efforts in teaching surgeons. We here present a review of recent controversies of the use of laparoscopy in colorectal surgery, such as in rectal cancer operations, the possibility of reproducing complete mesocolon excision, and the benefits of intra-corporeal anastomosis after right hemicolectomy. We also describe the results of latest innovations such as single incision laparoscopic surgery, robotic surgery and natural orifice transluminal endoscopic surgery for colon and rectal diseases

Watchful waiting after radiological guided drainage of intra-abdominal abscess in patients with Crohn's Disease might be associated with increased rates of stoma construction

Background: Management of spontaneous intra-abdominal abscess (IAA) in patients with Crohn's disease (CD) with radiologically guided percutaneous drainage (PD) was debated. Methods: This is a secondary analysis from a multicenter, retrospective cohort study of all the patients with CD who underwent PD followed by surgery at 19 international tertiary centers. Results: Seventeen patients (4.8%) who did not undergo surgery after PD were compared to those who had PD followed by surgical intervention 335/352 (95.2%). Patients who had PD without surgery were those with longer disease duration, more frequently had previous surgery for CD (laparotomies/laparoscopies), enteric fistula, on steroid treatment before and continue to have it after PD. Patients who had PD without subsequent surgical resection had a higher risk of stoma construction at later stages 8/17 (47.1%) versus 90/326 (27.6%) (P < .01). Patients with PD with no subsequent surgery had numerically higher rates of abscess recurrence 5/17 (29.4%) compared to those who had PD followed by surgery 45/335 (13.4%) the difference was not statistically significant (P = .07). Conclusions: Even with the low number of patients enrolled in this study who had PD of IAA without subsequent surgery, the findings indicate a markedly worse prognosis in terms of recurrence, length of stay, readmission, and stoma construction. Watchful waiting after PD to treat patients with spontaneous IAA might be indicated in selected patients with poor health status or poor prognostic factors

Mortality risk estimation in acute calculous cholecystitis: beyond the Tokyo Guidelines

Background: Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments. The recommended treatment is the early laparoscopic cholecystectomy; however, the Tokyo Guidelines (TG) advocate for different initial treatments in some subgroups of patients without a strong evidence that all patients will benefit from them. There is no clear consensus in the literature about who is the unfit patient for surgical treatment. The primary aim of the study is to identify the risk factors for mortality in ACC and compare them with Tokyo Guidelines (TG) classification. Methods: Retrospective unicentric cohort study of patients emergently admitted with and ACC during 1 January 2011 to 31 December 2016. The study comprised 963 patients. Primary outcome was the mortality after the diagnosis. A propensity score method was used to avoid confounding factors comparing surgical treatment and non-surgical treatment. Results: The overall mortality was 3.6%. Mortality was associated with older age (68 + IQR 27 vs. 83 + IQR 5.5; P = 0.001) and higher Charlson Comorbidity Index (3.5 + 5.3 vs. 0+2; P = 0.001). A logistic regression model isolated four mortality risk factors (ACME): chronic obstructive pulmonary disease (OR 4.66 95% CI 1.7-12.8 P = 0.001), dementia (OR 4.12; 95% CI 1.34-12.7, P = 0.001), age > 80 years (OR 1.12: 95% CI 1.02-1.21, P = 0.001) and the need of preoperative vasoactive amines (OR 9.9: 95% CI 3.5-28.3, P = 0.001) which predicted the mortality in a 92% of the patients. The receiver operating characteristic curve yielded an area of 88% significantly higher that 68% (P = 0.003) from the TG classification. When comparing subgroups selected using propensity score matching with the same morbidity and severity of ACC, mortality was higher in the non-surgical treatment group. (26.2% vs. 10.5%). Conclusions: Mortality was higher in ACC patients treated with non-surgical treatment. ACME identifies high-risk patients. The validation to ACME with a prospective multicenter study population could allow us to create a new alternative guideline to TG for treating ACC. Trial registration: Retrospectively registered and recorded in Clinical Trials. NCT04744441

The impact of additional margin coagulation with radiofrequency in liver resections with subcentimetric margin: can we improve the oncological results? A propensity score matching study

Background: Whereas the usefulness of radiofrequency (RF) energy as haemostatic method in liver surgery has become well established in the last decades, its intentional application on resection margins with the aim of reducing local recurrence is still debatable. Our goal was to compare the impact of an additional application of RF energy on the top of the resection surface, namely additional margin coagulation (AMC), on local recurrence (LR) when subjected to a subcentimeter margin. Methods: We retrospectively analyzed 185 patients out of a whole cohort of 283 patients who underwent radical hepatic resection with subcentimetric margin. After propensity score adjustment, patients were classified into two balanced groups according to whether RF was applied or not. Results: No significant differences were observed within groups in baseline characteristics after PSM adjustment. The LR rate was significantly higher in the Control than AMC Group: 12 patients (14.5%) vs. 4 patients (4.8%) (p = 0.039). The estimated 1, 3, and 5-year LR-free survival rates of patients in the Control and AMC Group were: 93.5%, 86.0%, 81.0% and 98.8%, 97.2%, 91.9%, respectively (p = 0.049). Univariate Cox analyses indicated that the use of the RF applicator was significantly associated with lower LR (HR = 0.29, 95% confidence interval 0.093-0.906, p = 0.033). The Control Group showed smaller coagulation widths than the AMC group (p < 0.001). Conclusions: An additional application of RF on the top of the resection surface is associated with less local hepatic recurrence than the use of conventional techniques.This work was partially supported by the Spanish Ministerio de Ciencia, Innovación y Universidades under “Programa Estatal de I+D+i Orientada a los Retos de la Sociedad”, Grants Nº “ RTI2018-094357-B-C21 ” and “ RTI2018-094357-B-C22”

El tatuaje endoscópico en las neoplasias colorrectales intervenidas vía laparoscópica: una propuesta de marcaje selectivo

RESUMEN Introducción y objetivo: el tatuaje endoscópico preoperatorio es un procedimiento eficaz que permite la localización intraoperatoria de neoplasias de pequeño tamaño. Sin embargo, actualmente no existen unos criterios definidos sobre las indicaciones del tatuaje endoscópico de estas neoplasias en el momento del diagnóstico. El objetivo es establecer unos criterios endoscópicos para seleccionar los pacientes que precisarán un tatuaje. Material y métodos: estudio ambispectivo de pacientes intervenidos de neoplasia colorrectal por laparoscopia en los que se realizó tatuaje endoscópico en el periodo (2007-2013 y 2016-2017). De acuerdo con la descripción endoscópica de las neoplasias se clasificaron en: lesiones polipoideas, neoplasias que ocupan < 50% o ≥ 50% de la luz intestinal y neoplasias estenosantes. Resultados: se realizó tatuaje de la lesión en 120 pacientes y en 114 (95%) se identificó el mismo durante la cirugía. La mayor parte de las neoplasias descritas como polipoideas y neoplasias que ocupaban < 50% de la luz intestinal no se visualizaban en la cirugía y por tanto precisaban el tatuaje (33 de 42 y 18 de 26 respectivamente, p = 0.0001, 2). En cambio, aquellas lesiones estenosantes o bien neoplasias que ocupaban ≥ 50% de la luz intestinal se identificaban mayoritariamente en la cirugía (15 de 15 y 36 de 37 respectivamente, p = 0.0001, 2) sin necesidad de tatuaje. En conjunto la identificación de las neoplasias según los criterios establecidos fue del 98%. Conclusiones: estos resultados sugieren que es posible establecer unos criterios endoscópicos que permitan realizar un tatuaje selectivo durante la endoscopia diagnóstica manteniendo el éxito del mismo

An interventional nationwide surveillance program lowers postoperative infection ratesin elective colorectal surgery. A cohort study (2008-2019)

Colorectal surgery is associated with the highest rate of surgical site infection (SSI). This study analyses the effectiveness of an interventional surveillance program on SSI rates after elective colorectal surgery. Material and methods Cohort study showing temporal trends of SSI rates and Standardized Infection Ratio (SIR) in elective colorectal surgery over a 12-year period. Prospectively collected data of a national SSI surveillance program was analysed and the effect of specific interventions was evaluated. Patient and procedure characteristics, as well as SIR and SSI rates were stratified by risk categories and type of SSI analysed using stepwise multivariate logistic regression models. Results In a cohort of 42,330 operations, overall cumulative SSI incidence was 16.31%, and organ-space SSI (O/S-SSI) was 8.59%. There was a 61.63% relative decrease in SSI rates (rho = −0.95804). The intervention which achieved the greatest SSI reduction was a bundle of 6 measures. SSI in pre-bundle period was 19.73% vs. 11.10% in post-bundle period (OR 1.969; IC 95% 1.860-2.085; p < 0.0001). O/S-SSI were 9.08% vs. 6.06%, respectively (OR 1.547; IC 95% 1.433-1.670; p < 0.0001). Median length of stay was 7 days, with a significant decrease over the studied period (rho = −0.98414). Mortality of the series was 1.08%, ranging from 0.35% to 2.0%, but a highly significant decrease was observed (rho = −0.67133). Conclusions Detailed analysis of risk factors and postoperative infection in colorectal surgery allows strategies for reducing SSI incidence to be designed. An interventional surveillance program has been effective in decreasing SIR and SSI rates

Caecal volvulus and jejunostomy: challenging diagnostic

Caecal volvulus represent the 20-40% of colonic volvulus, being the second most frequent localization. It causes intestinal occlusion symptomatology (nausea, vomiting, abdominal distension). We present a case of 45-year-old women with feeding jejunostomy tube due to connatal anoxia. She arrives at A&E after 12 h of vomits and abdominal pain. The CT scan shows a small intestine dilation that suggested a small intestine volvulus. A laparotomy is performed showing a caecal volvulus, so ileo-cequectomy with primary anastomosis is performed. After several complications, she was discharged after 60 days of hospital stay. Caecal volvulus can be challenging to diagnose by clinic, because it can be hardly differenced from other intestinal occlusion causes. CT scan can be useful to reach the diagnostic and see signs of tissue suffering. In contrast with sigma volvulus, endoscopic treatment has not shown any benefit to solve it
