Textbook outcome in colon carcinoma: implications for overall survival and disease-free survival.

BACKGROUND: Textbook outcome (TO) is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. The aim of the present study is to record the rate of TO in patients undergoing elective surgery for colon cancer (CC). MATERIAL AND METHODS: Retrospective study of all patients undergoing scheduled CC surgery at a Spanish university hospital from September 2012 to August 2016. Patients with rectal cancer were excluded. The variables included in the definition of TO were: R0 resection, number of isolated nodes ≥ 12, no Clavien-Dindo ≥ IIIa complications, no prolonged stay, no readmissions, and no mortality in the first 30 days. The main objective of this study is to analyse the achievement of TO in these patients and to assess the relationship between TO and overall and disease-free survival. RESULTS: Five hundred and sixty-four patients were included in the study. TO was achieved in 49.8%. The sample had a mean age of 69 ± 11 years, and 60% were male. Female sex (OR 1.61; 95% CI 2.30-1.13), T3 and T4 classification (OR 2.50, 95% CI 4.59-1.36, and OR 2.55, 95% CI 5.21-1.24 respectively) and laparoscopic approach (OR 1.53, 95% CI 2.33-1.00) were independent factors that were significantly associated with achieving a TO. Patients who achieved TO had higher overall survival (p = 0.008) than those who did not. However, with regard to disease-free survival, no statistically significant differences were found (p = 0.303). CONCLUSION: TO is a useful, easy-to-interpret management tool for measuring oncological results and for predicting patient survival.

[Intussusception in the adult: a rare cause of mechanical obstruction]. / Invaginación intestinal en el adulto. Una causa infrecuente de obstrucción mecánica.

Intussusception is an infrequent cause of mechanical intestinal obstruction in the adult. We present herein two clinical cases of intussusception with different etiologies. In the first case, the underlying cause was a lipoma, and in the second, it was metastasis from melanoma. In both cases the intussusception was identified through computed tomography and treatment was intestinal resection. Pathologic anatomy provided the definitive diagnosis. Etiology is diverse and it is more common for obstruction to be due to organic lesions that are malignant at the level of the colon and benign at the level of the small bowel. Currently there are more preoperative diagnoses thanks to the advances made in imaging study techniques. Intestinal resection continues to be the treatment of choice in the majority of cases, because of the high percentage of malignant lesions as the underlying cause.

[Low back pain as a manifestation of an intra-abdominal desmoplastic small round cell tumor]. / Dolor lumbar como manifestación de un tumor intra-abdominal desmoplásico de células pequeñas y redondas.

The desmoplastic small round cell tumor is infrequent.That mainly affects male youngsters and is normally located at the abdomino-pelvic cavity, being its clinic unspecific. The diagnosis is confirmed by the presence of a specific chromosomal translocation: t (11; 22), (p13; q12). As to its treatment, it is mostly recommended to follow a multimodal aggressive one. We present the case of a man, whose atypicality is due to his advanced age (63 years old) and the symptoms he presents (lumbar ache).
