RESUMO

BACKGROUND AND AIMS: Laparoscopic sleeve gastrectomy (LSG)-related fistulas are important and potentially fatal complications. We aimed at determining the incidence, predictive factors, and management of recurrence of post-LSG fistulas. METHODS: This is a retrospective cohort study of 12 consecutive patients with LSG fistulas managed endoscopically between 2008 and 2013. We analyzed factors associated with recurrence of post-LSG fistulas and the efficacy of a primarily endoscopic approach to manage fistula recurrence. RESULTS: The average age at fistula detection after LSG was 43.3 ± 10.9 years, and 10 (83%) patients were female. The median interval between surgery and initial fistula detection was 14 (4-145) days. Fistulas were located at the gastric cardia in 9/12 patients. A median of 4 (1-10) endoscopies were performed per patient until all fistulas were successfully closed. The median follow-up was 30.5 (15-72) months. Fistula recurrence was detected in 3 (25%) female patients with an average age of 31.7 ± 7.9 years after a median of 119 (50-205) days of the initial fistula closure. Fistulas in all 3 patients recurred at the gastric cardia and were successfully managed endoscopically. There was a second recurrence in 1 patient after 6 months, and she was re-operated with anastomosis of a jejunal loop at the site of the fistula orifice at the gastric cardia. We did not find any factors at initial fistula detection that were significantly associated with fistula recurrence. There were no deaths related to initial fistula after LSG and fistula recurrence. CONCLUSIONS: A primarily endoscopic approach is an effective and safe method for the management of fistulas after LSG. Fistula recurrence occurred in 25% of patients and was managed endoscopically. KEY MESSAGES: Although we could not define predictive factors of post-LSG fistula recurrence, it is a clinical reality and can be managed endoscopically.


OBJECTIVOS: As fistulas pós-gastrectomia vertical (sleeve) laparoscópica (LSG) são complicações importantes e potencialmente fatais. O objectivo do estudo foi determinar a incidência, factores preditivos e manejo da recorrência de fistulas pós LSG. MÉTODOS: Estudo retrospectivo de 12 doentes com fistulas pós LSG manejados endoscopicamente entre 2008 e 2013. Analisámos factores associados à recorrência de fistulas pós LSG e a eficácia da abordagem endoscópica. RESULTADOS: Idade média na detecção das fistulas pós LSG foi de 43.3 ± 10.9 anos e 10 (83%) doentes eram mulheres. O intervalo mediano entre a cirurgia e a detecção da fistula inicial foi de 14 (4­145) dias. As fistulas localizaram-se no cárdia em 9/12 doentes. Foram realizadas em mediana 4 (1­10) endoscopias por doente até ao encerramento eficaz das fistulas. O tempo mediano de seguimento foi de 30.5 (15­72) meses. A recorrência das fistulas foi detectada em 3 (25%) doentes, todas mulheres, com idade média de 31.7 ± 7.9 anos, após um tempo mediano de 119 (50­205) dias após encerramento da fistula inicial. As recorrências das fistulas nas três doentes ocorreram no cárdia e foram manejados endoscopicamente.Houve uma segunda recorrência de fistula numa doente após 6 meses que foi reoperada com anastomose de ansa jejunal no local do orifício de fistula no cárdia. Não conseguimos determinar factores na altura da detecção da fistula inicial pós LSG significativamente associados com recorrência de fistulas. Não houve mortalidade associada às fistulas pós LSG (inicial ou recorrência). CONCLUSÕES: A abordagem primariamente endoscópica das fistulas pós LSG é um método eficaz e seguro. A recorrência de fistulas ocorreu em 25% dos doentes. As recorrências de fistulas pós LSG são manejáveis endoscopicamente. MENSAGENS CHAVE: Embora não tenhamos conseguido definir factores preditivos de recorrência de fistulas pós LSG, a recorrência de fistulas é uma realidade clínica e é manejável endoscopicamente.

RESUMO

Bariatric surgery is recognized as the most effective method for achieving relevant weight loss in subjects with severe obesity. However, there is insufficient knowledge about weight self-regulation and quality of motivation in these patients. The main goal of this study was to characterize the association between the percentage of excess weight loss (%EWL) and the motivation to manage weight, at least 1 year after sleeve gastrectomy (SG). This is an observational longitudinal retrospective study. All patients corresponding to predefined inclusion criteria who underwent SG from January 2008 to July 2010 at a main general hospital were invited. A version of the Treatment Self-Regulation Questionnaire (TSRQ) was used to assess patients' quality of motivation: TSRQ concerning continuing the weight self-management program. Clinical data were collected from patients' records. Overall, 81 patients participated (16 men and 65 women, 25-64 years old). The average body mass index was significantly reduced from 45.3 ± 7.0 kg/m2 preoperatively to 32.7 ± 6.9 kg/m2 postoperatively. Autonomous self-regulation was higher than externally controlled self-regulation, regarding motives to keep managing weight after SG. Postoperatively, %EWL correlated negatively with external self-regulation. SG was found to be associated with the quality of motivation for losing weight. External motivations were associated with worse results. These findings support the importance of multiprofessional teams in the assessment and treatment of patients, aiming for the promotion of weight self-regulation after bariatric surgery.

RESUMO

Background. We analyzed the incidence, risk factors, and prognosis of acute kidney injury (AKI) in a cohort of patients undergoing major abdominal surgery. Methods. A total of 450 patients were retrospectively studied. AKI was defined by an increase in serum creatinine (SCr) ≥ 0.3 mg/dl or by an increase in SCr ≥ 50% and/or by a decrease in urine output to 0.5 ml/kg/hour for 6 hours, in the first 48 hours after surgery. Logistic regression method was used to determine predictors of AKI and in-hospital mortality. A two-tailed P value <0.05 was considered significant. Results. One hundred one patients (22.4%) had postoperative AKI. Age (adjusted odds ratio (OR) 1.02, 95% confidence interval (CI) 1.01-1.05), nonrenal Revised Cardiac Risk Index score (adjusted OR 1.9, 95% CI 1.3-3.1, P = 0.003), intraoperative erythrocytes transfusions (adjusted OR 2.2, 95% CI 1.4-3.5, P <.0001), and nonrenal Simplified Acute Physiology Score II (adjusted OR 1.03, 95% CI 1.01-1.06, P = 0.0191) were associated with postoperative AKI. AKI was associated with increased in-hospital mortality (20.8% versus 2.3%, P <.0001; unadjusted OR 11.2, 95% CI 4.8-26.2, P <.0001; adjusted OR 3.7, 95% CI 1.2-11.7, P = 0.024). Conclusion. AKI was common in patients undergoing major abdominal surgery and was associated with in-hospital mortality.

RESUMO

Pheochromocytoma is a tumor originating from chromaffin tissue. It commonly presents with symptoms and signs of catecholamine excess, such as hypertension, tachycardia, headache and sweating. Cardiovascular manifestations include catecholamine-induced cardiomyopathy, which may present as severe left ventricular dysfunction and congestive heart failure. We report a case of pheochromocytoma which was diagnosed following investigation of dilated cardiomyopathy. We highlight the dramatic symptomatic improvement and reversal of cardiomyopathy, with recovery of left ventricular function after treatment.

RESUMO

Carcinoid heart disease typically presents with pulmonary stenosis and tricuspid regurgitation. Management is intended for symptomatic relief, and valvular intervention is indicated in refractory heart failure. Balloon valvuloplasty is an option for patients not suitable for surgery. We report the case of a patient with a carcinoid tumour, who developed postoperative refractory hypoxemia. Transthoracic echocardiogram revealed carcinoid pulmonary and tricuspid valve disease, with severe pulmonary stenosis. Balloon valvuloplasty was performed with major clinical improvement.
