Specific training in coloproctology: cross-sectional cohort study through the Young Group of the Spanish Association of Coloproctology

INTRODUCTION

Specific training at surgical super-specialities and its objective evaluation is a challenge nowadays in order to measure the potential benefits that it might add.

MATERIAL AND METHODS

An online survey addressed by the "Grupo Joven de la Asociación Española de Coloproctología" has been performed in order to evaluate the level of formation achieved specifically at colorectal surgery.

RESULTS

128 surgeons participated, representing 81 colorectal surgery units. Mean satisfaction after the period of formation was moderate to high in 84% of the ones polled. The main points of improvement were the realization of advanced surgical techniques (52%) and academic questions (45%). The big part of the respondents has performed simple proctologic procedures (98%) and oncological open colic resections (100%) during their training period, observing the scarcity of related pelvic floor procedures (20%) and diagnosis techniques (10-45%). Scientific production (31,5%) and presentation of studies at congresses (82,8%) have been moderated. No differences between accredited units and non-accredited units have been observed.

CONCLUSIONS

Specific formation in colorectal surgery is appropriate, with a high level of simple procedures and open surgery performed by personal at formation. In view of these results, it seems logical to think that even though is necessary a progress in the formation of minimal invasive and diagnosis techniques.

National observational study about the surgical treatment of anal fistula: Does the kind of hospital modify the results?

INTRODUCTION

Performing the surgical procedure in a high-volume center has been seen to be important for some surgical procedures. However, this issue has not been studied for patients with an anal fistula (AF).

MATERIAL AND METHODS

A retrospective multicentric study was performed including the patients who underwent AF surgery in 2019 in 56 Spanish hospitals. A univariate and multivariate analysis was performed to analyse the relationship between hospital volume and AF cure and fecal incontinence (FI).

RESULTS

1809 patients were include. Surgery was performed in a low, middle, and high-volume hospitals in 127 (7.0%), 571 (31.6%) y 1111 (61.4%) patients respectively. After a mean follow-up of 18.9 months 72.3% (1303) patients were cured and 132 (7.6%) developed FI. The percentage of patients cured was 74.8%, 75.8% and 70.3% (p = 0.045) for low, middle, and high-volume hospitals. Regarding FI, no statistically significant differences were observed depending on the hospital volume (4.8%, 8.0% and 7.7% respectively, p = 0.473). Multivariate analysis didńt observe a relationship between AF cure and FI.

CONCLUSION

Cure and FI in patients who underwent AF surgery were independent from hospital volume.

Classifying early-onset colorectal cancer according to tumor location: new potential subcategories to explore

Early-onset Colorectal Cancer (ECRC) represents a significant and increasing proportion of Colorectal Cancer (CRC), but it is a heterogeneous entity that probably encompasses specific subclasses. On the premise that the carcinogenetic mechanism and progression of CRC may differ with location, we analyzed molecular and clinical characteristics of ECRC according to tumor location in order to identify more homogeneous subgroups of CRC. Right-sided ECRC is a subset in which most Lynch Syndrome cases are found, with earlier stages at diagnosis and better prognosis. At this location the CpG Island Methylator Phenotype (CIMP) is predominant and Chromosomal Instability (CI) is rare. Left-sided ECRC appears as a transitional or intermediate location, except for CI tumors, that seem to predominate at this location. Finally, rectal ECRC shows Microsatellite Stability, CIMP low-0 and low CI - with recurrent altered chromosomal regions in common with left-sided ECRC-, possibly in relation with Microsatellite And Chromosomal Stable tumors, but with an unexpected familial component and worse prognosis. All this suggest that the molecular basis of ECRC varies with tumor location, which could affect the clinical management of patients.
