The Impact of the Length of the Common Intestinal Loop on Metabolic and Nutritional Outcomes of Patients with Severe Obesity Who Undergo of Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy: 5-Year Follow-Up.

Introduction: Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a recent bariatric surgery technique, highly effective in terms of weight loss. Nevertheless, data regarding the impact of SADI-S at mid-long term (after >5 years of follow-up) are scarce. Objectives: To evaluate the effect of lengths of common intestinal loop on the evolution of patients with morbid obesity (MO), who undergo SADI-S. Materials and Methods: Descriptive study (case series), including patients with MO who underwent SADI-S procedure between January 2012 and December 2015 with at least 5 years of follow-up. Patients were classified as "Old-SADI-S" (OS) when length of the common alimentary loop was <2.5 m and "New-SADI-S" (NS) when length was >2.5 m. Clinical parameters and nutritional parameters were included. Results: Twenty-nine cases were included (17 OS; 12 NS), 86.2% women and mean age 46.7 ± 1 years. After 12 months, OS had significantly lower body mass index (29.7 ± 4.8 kg/m2 versus 32.0 ± 5.1 kg/m2, P = .01), without significant differences in the resolution of comorbidities. Nevertheless, OS group had severe malabsorptive complications requiring surgical conversion of OS to NS in 7 patients after 8 months. At 5 years of follow-up, no significant difference was seen between the two groups and resolution of comorbidities was maintained during this period of time. Conclusions: SADI-S is effective in terms of weight loss and resolution of comorbidities at 5 years of follow-up, regardless of the length of the common intestinal loop. However, a common intestinal loop <2.5 m was associated with severe malabsorptive complications that determined the surgical re-conversion in all cases.

Resultados y factores pronósticos de mortalidad en la intervención de Hartmann / Results and prognostic factors in the Hartmann procedure

Introducción. La introducción, hace ya muchos años, de la cirugía cólica urgente en un tiempo ha relegado la intervención de Hartmann para los pacientes más graves. Este hecho ha conducido a que las tasas de morbimortalidad asociadas a la técnica de Hartmann sean elevadas. El objetivo de nuestro estudio fue analizar los resultados obtenidos con la intervención de Hartmann en el período de estudio y analizar los factores pronósticos de mortalidad postoperatoria en este grupo de pacientes. Pacientes y métodos. Durante el período comprendido entre enero de 1995 y diciembre de 2000 se intervino quirúrgicamente a 79 pacientes (34 varones y 45 mujeres), con una edad media de 71,5 años, a los que se les realizó una intervención de Hartmann. Casi la totalidad de los pacientes (91,1%) tenía una o más enfermedades asociadas. En este grupo de pacientes se analizaron retrospectivamente los resultados de morbimortalidad y, mediante un estudio de regresión logística multivariable, los factores pronósticos de mortalidad postoperatoria. Resultados. En toda la serie, la indicación de cirugía fue: peritonitis aguda (77,2%), oclusión intestinal (18,9%) y hemorragia digestiva baja (3,7%). La causa etiológica más frecuente fue la diverticulitis aguda complicada (36 casos) y el cáncer colorrectal complicado (18 casos). El 70,9% de los pacientes (56 casos) presentó 1 o más complicaciones durante el postoperatorio;15 casos fueron reintervenidos (18,9%), y la mortalidad postoperatoria fue del 45,5%. La insuficiencia renal (creatinina ≥ 120 µmol/l) y el riesgo quirúrgico ASA avanzado (III o IV) alcanzaron significación estadística cómo factores predictivos de mortalidad en estos pacientes (p = 0,001 y 0,005, respectivamente). Conclusión. Los pacientes a los que se les practicó una intervención de Hartmann y que tenían un mayor riesgo quirúrgico anestésico (ASA) y/o una alteración de la función renal tuvieron un riesgo de mortalidad significativamente más elevado (AU)

Introduction. The introduction of one-stage procedures in emergency colonic surgery many years ago has relegated the use of the Hartmann procedure to the most seriously-ill patients, which has led to the high morbidity and mortality rates associated with this surgical technique. The aim of our study was to investigate our results using Hartmann’s procedure and to evaluate several prognostic factors of postoperative mortality in this group of patients. Patients and methods. From January 1995 to December2000, 79 patients (34 men and 45 women) with a mean age of 71.5 years underwent Hartman’s operation. Almost all the series (91.1%) had comorbidities. In this group of patients, morbidity and mortality were analyzed retrospectively, and a multivariate logistic regression analysis was performed to study prognostic factors of postoperative mortality. Results. The indications for surgery were acute peritonitis(77.2%), intestinal obstruction (18.9%), and lower gastrointestinal hemorrhage (3.7%). The most frequent etiology was acute diverticulitis (36 patients),followed by complicated colorectal carcinoma (18 patients). In 70.9% of the patients (56 patients) one or more postoperative complications was observed. Reoperation was performed in 15 patients (18.9%) and overall postoperative mortality was 45.5%. Renal failure (creatinine ≥ 120 µmol/l) and high surgical ASA score (III or IV) reached statistical significance as predictive factors of mortality in these patients(p=.001 and p=.005, respectively). Conclusion. The patients who underwent Hart-mann’s procedure with high surgical ASA score and/or renal failure were at significantly higher risk of mortality (AU)
