- ItemConsistency between POLARS and LARS scores regarding the incidence of low anterior resection syndrome in a Chilean population undergoing rectal surgery secondary to cancer in a high-volume hospital(2023) Gaete Dañobeitia, María Inés; Moreno, D. ; Iglesias, A. ; Navarro Subiabre, Francisco Fabián; Dreyse, J. ; Cerda, Jaime; Durán Espinoza, Valentina; Molina Pezoa, María Elena; Miguieles Cocco, Rodrigo Alfonso; Urrejola Schmied, Gonzalo Ignacio; Larach Kattan, José Tomás; Bellolio R., FelipeAim: The aim of this work was to evaluate the concordance between the low anterior resection syndrome (LARS) and preoperative LARS (POLARS) scores regarding the incidence of LARS in a Chilean population undergoing rectal surgery for cancer in a high-volume hospital. Method: The LARS score questionnaire, following telephone requests, was used to determine the presence and severity of LARS. The POLARS score was calculated based on variables described previously. Correlations and qualitative and quantitative concordance were evaluated using Spearman's correlation coefficient, the kappa coefficient and the Bland–Altman plot with Lin's concordance correlation coefficient. Results: A total of 120 patients met the inclusion criteria: 37.5% underwent neoadjuvant radiotherapy, 61% underwent total mesorectal excision (TME) and 51.6% underwent ostomy. A total of 49% of patients did not present with LARS, whereas 28% had major LARS. The correlation between scales was poor, with a fair qualitative concordance to determine the presence/absence of LARS and a slight qualitative concordance to determine the degree of the intensity. The quantitative concordance was poor. Conclusion: In the Chilean population, concordance between the LARS and POLARS scores was qualitatively fair to determine the presence/absence of the disease and qualitatively slight to determine the degree of intensity. We do not suggest using the POLARS score in the perioperative period in the Chilean population deliberately, as the score may help to determine the presence/absence of LARS but cannot determine its degree of intensity. Additional evaluations are required to determine the factors contributing to the degree of agreement between the scales.

- ItemReservorio ileal con anastomosis reservorio anal por colitis ulcerosa: Complicaciones y resultados funcionales a largo plazo(2008) Zárate, Alejandro José; Zuñiga Díaz, Álvaro; Pinedo Mancilla, George; López K, F.; Molina Pezoa, María Elena; Viviani García, PaolaBackground: The ileo anal-pouch-anastomosis (IPAA) is the treatment of choice for patients with ulcerative colitis (UC). Aim: To analyze the surgical outcomes, long term evolution and functional results of IPAA. Material and methods: All patients subjected to an IPAA, from 1984 to 2006 were identified from a prospectively constructed inflammatory bowel disease database. Surgical variables, postoperative complications and functional evaluation, using Öresland score were analyzed. Chi square, Fischer exact test, T Student, Mann Whitney and binary logistic regression were included in the statistical analysis. Results: In the study period 107 patients, aged 14 to 62 years (61 females), subjected to an IPAA, were identified in this period. All patients, except 4, had a J pouch. All were protected with a loop ileostomy. Thirteen patients (12.1%) had specific postoperative complications: pelvic collections in five (4.6%), wound infection in four (3.7%), fistula of the anastomosis in two (1.8%), hemoperitoneum and pouch necrosis in one each. Three (2.7%) patients were reoperated. There was no post-operative (30 days) mortality. A complete follow-up was obtained in 106 of 107 patients: four evolved as Crohn disease; four lost their pouch and two died for other causes. One patient required an ileostomy due to a vaginal fistula. Seventy two patients were followed more than 36 months after ileostomy closure and 92% have a satisfactory intestinal function. In the univariate analysis, poorest intestinal function was related to age of diagnosis of UC and presence of chronic pouchitis. In the multivariate analyses age of diagnosis was associated with poor function. Conclusions: IPAA has a low rate of complications. The long term intestinal function is satisfactory in most patients. A poorer intestinal function was observed in older patients and those with chronic pouchitis (Rev Méd Chile 2008; 136: 467-74).
