Postoperative outcomes and functional results after Deloyer's procedure - a retrospective cohort study / Desfechos pós-operatórios e resultados funcionais após o procedimento de Deloyer ­ um estudo de coorte retrospectivo

ABSTRACT Introduction: The objective of our study was to describe surgical outcomes of Deloyers procedure in our referral center, and to compare the results of patients with and without protective ileostomy. Methods: Patients undergoing a Deloyers procedure from 2013 to 2016 were prospectively included. General characteristics, intraoperative variables, postoperative course, and functional outcomes were analyzed. Patients were compared into two groups: group (1) patients undergoing Deloyers procedure without ileostomy, and group (2) Deloyers procedure with protective ileostomy. Results: Sixteen patients undergoing isoperistaltic transposition of the right colon remnant were included, of which 9 (63%) were males with a median age of 47 (range 22-76) years. The main surgical indication was the restoration of bowel transit (62.5%). There was higher major morbidity rate in the Deloyers procedure with protective ileostomy group, but without statistical significance (20% vs. 9%, p = 0.92). No leaks or deaths were reported. The length of hospital stay was 7 days. The mean number of bowel movements per day was 4 at 18 months of follow up. Only four (25%) patients used irregularly loperamide. Conclusions: The Deloyers procedure has satisfactory results and is reproducible with low morbidity. The major and minor morbidity rates were similar between groups, suggesting that the costs and risks of a second procedure can be avoided by providing a safe primary anastomosis.

RESUMO Introdução: O objetivo de nosso estudo foi descrever os resultados cirúrgicos do procedimento de Deloyer em nosso centro de referência e comparar os resultados de pacientes com e sem ileostomia de proteção. Métodos: Pacientes submetidos ao procedimento de Deloyer de 2013 a 2016 foram incluídos prospectivamente. Foram analisadas as características gerais, as variáveis intraoperatórias, o curso pós-operatório e os desfechos funcionais. Os pacientes foram comparados em dois grupos: Grupo 1) pacientes submetidos ao procedimento de Deloyer (PD) sem ileostomia, e grupo 2) procedimento de Deloyer com ileostomia de proteção (IP). Resultados: Foram incluídos 16 pacientes submetidos à transposição isoperistáltica da porção remanescente do cólon direito, dos quais 9 (63%) eram do sexo masculino com idade média de 47 anos (variação de 22-76) anos. A principal indicação cirúrgica foi a restauração do trânsito intestinal (62,5%). Houve maior morbidade maior no grupo IP, mas sem significância estatística (20% vs. 9%, p = 0,92). Nenhum vazamento ou óbito foi relatado. A duração da hospitalização foi de 7 dias. O número médio de evacuações por dia foi 4, aos 18 meses de seguimento. Apenas quatro (25%) pacientes utilizaram irregularmente a loperamida. Conclusões: O procedimento de Deloyer tem resultados satisfatórios e é reprodutível com baixa morbidade. As taxas de morbidades maiores e menores foram semelhantes entre os grupos, sugerindo que os custos e riscos de um segundo procedimento podem ser evitados proporcionando-se uma anastomose primária segura.

Weight loss and improvement of lipid profiles in morbidly obese patients after laparoscopic one-anastomosis gastric bypass: 2-year follow-up.

BACKGROUND: Obesity is the most frequent chronic metabolic disease globally. There is a direct correlation between increasing body mass index (BMI) and elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL), and triglycerides (Tg), and an inverse correlation with high-density lipoprotein cholesterol (HDL); all these lipid derangements are associated with an increased risk of cardiovascular disease. Our aim was to evaluate lipid profiles in morbidly obese patients before and after one-anastomosis gastric bypass (OAGB) performed at a single-center during a 2-year follow-up. PATIENTS AND METHODS: A prospective, observational and descriptive study was carried out, including morbidly obese patients with at least one lipid abnormality, who underwent laparoscopic OAGB. Lipid profiles were evaluated preoperatively and at different intervals during a 2-year follow-up. RESULTS: A total of 150 patients were included (73 % females and 27 % males). Mean age was 45.83 ± 10.65 years, mean BMI was 42.82 kg/m2 ± 6.43, and mean weight was 116.23 kg ± 22.70; 2 years after surgery, the latter two decreased to 24.73 ± 4.43 (p < 0.001) and 67.34 ± 13.35 (p < 0.001), respectively, thus leading to a mean weight loss (WL) of 48.85 kg ± 15.64 and mean %excess WL of 71.87 ± 13.41. Tg, TC and LDL levels significantly decreased: 123.60 ± 56.34 versus 84.79 ± 33.67, 194.33 ± 43.90 versus 173.65 ± 34.84, and 124.47 ± 36.07 versus 97.36 ± 25.05, respectively (p < 0.001); HDL levels significantly increased: 43.61 ± 9.85 versus 61.56 ± 12.63 (p < 0.001). CONCLUSION: OAGB leads to substantial and durable WL in morbidly obese patients after a 2-year follow-up. Postoperative lipid profiles significantly improved; these changes translate into theoretical relevant cardiovascular risk benefits.

Stem cell transplantation in amyotrophic lateral sclerosis patients: methodological approach, safety, and feasibility.

Amyotrophic lateral sclerosis is characterized by the selective death of motor neurons. Stem cells have been proposed as a potential therapeutic strategy. The safety of stem cell transplantation into the frontal motor cortex to improve upper motor neuron function is described. Sixty-seven patients with definite amyotrophic lateral sclerosis were included. After giving their informed consent, the patients underwent magnetic resonance imaging, functional rating, pulmonary function test, and laboratory tests. Their bone marrow was stimulated with daily filgrastim (300 µg) given subcutaneously for 3 days. Peripheral blood mononuclear cells were obtained by leukapheresis. Isolated CD133(+) stem cells were suspended in 300 µl of the patient's cerebrospinal fluid and implanted into the motor cortex. Adverse events were recorded at each step of the procedure and were classified according to the Common Terminology Criteria for Adverse Events v3.0. The survival at 1 year was 90% after transplantation. with a mean long-term survival rate of 40.17 months from diagnosis. The most common adverse events were in grades I-II and involved transient skin pain (19.5% of patients) attributed to the insertion of the Mahurkar catheter into the subclavian vein, minor scalp pain (15.9%), and headache (12.2%) from the surgical procedure. Several patients (1.5 - 4.5%) reported diverse grade I adverse events. There were two deaths, one considered to be associated with the procedure (1.5%) and the other associated with the disease. Autologous stem cell transplantation into the frontal motor cortex is safe and tolerated well by patients. Further controlled studies are required to define the efficacy of this procedure.

Survival and clinical features in Hispanic amyotrophic lateral sclerosis patients.

The demography, survival, and motor phenotypes of amyotrophic lateral sclerosis (ALS) patients have been rarely described in Hispanic countries. The clinical characteristics and survival of a series of Mexican ALS patients are described. Mexican patients with definite ALS were included in a five-year retrospective longitudinal study. Their demographic and clinical features, cumulative survival rates, and independent predictive factors for survival were analysed. Sixty-one definite ALS patients were included. The median follow-up period was 35 months (range 12-108 months). Males were predominant (1.8: 1), the mean age at onset was 47.5 ± 10.5 years, and the median interval from onset to diagnosis was 12 months. Spinal onset occurred in 66% of patients. Upper motor neuron phenotype was predominant in 53% of patients. The overall mean survival from onset was 68.6 months, and from diagnosis was 57.8 months. Longer survival was determined in patients aged ≤ 40 years (54.7 months) compared with other age groups (p = 0.006). In conclusion, the clinical heterogeneity, male predominance, and survival rates in our sample are consistent with those of other studies. Patients in this series had a younger age at onset and a clear trend toward longer survival compared with those of other population studies.
