RESUMO
OBJECTIVE OR BACKGROUND: To report the investigational device exemption (IDE) study 1-year clinical outcomes of the high neck angulation (HNA) substudy of the GORE® EXCLUDER® Conformable AAA Endoprosthesis (EXCC) for treatment of infrarenal abdominal aortic aneurysms (AAA). METHODS: This study is a prospective, multicenter clinical trial conducted in the United States and included core laboratory assessment of imaging and independent event adjudication. Anatomic criteria for enrollment in the HNA substudy included infrarenal aortic neck angulation >60° and ≤90° with aortic neck length ≥10 mm. Primary safety endpoints included blood loss >1000 mL, death, stroke, myocardial infarction, bowel ischemia, paraplegia, respiratory failure, renal failure, and thromboembolic events. Primary effectiveness endpoints included technical success, absence from Type I and III endoleak, migration (≥10 mm), sac enlargement (≥5 mm), sac rupture, and conversion to open repair. RESULTS: Between January 2018 and February 2022, 95 patients were enrolled in the HNA substudy across 35 sites. Of the 95 patients, 71 (74.7%) were male and the cohort average age was 74.4 years old. The mean infrarenal proximal aortic neck angle was 71.6° and mean AAA size was 62.9 mm. Overall technical success was achieved in 93 (97.9%) patients. Freedom from a primary safety endpoint through 30 days was 96.7%; 3 (3.3%) patients had blood loss >1000 mL. Freedom from the primary effectiveness at 12 months was achieved in 94.8%. Four (4.3%) patients had Type IA endoleak; intervention after the procedure was not required and no subsequent interventions or sac enlargement were noted in these patients. At 12 months, 29 (39.7%) patients experienced a Type II endoleak and 1 (1.3%) patient experienced AAA sac expansion ≥5mm. Through 12 months, 1 (1.3%) patient had a conversion to open surgical repair. There were no aneurysm-related deaths, ruptures, or migration through 12 months. CONCLUSIONS: The IDE study demonstrates safety and effectiveness of the EXCC device in AAA with highly angulated necks (>60° and ≤90°) are preserved at the 12-month follow-up.
RESUMO
Goblet cell carcinoid tumor is a rare form of carcinoid tumor of the appendix. It behaves more aggressively than classical carcinoid tumor of the appendix. Thus, special attention must be given to its disease course and treatment. Our case presentation is of a 68-year-old female who presented with abdominal pain. Computed tomography of her abdomen and pelvis showed a perforated appendicitis. She underwent an ileocectomy with pathological report showing a goblet cell carcinoid tumor of the appendix with negative lymph nodes. A subsequent colonoscopy done 5 months later showed no synchronous lesions and a healthy anastomosis. Given the limited amount of data available about goblet cell carcinoid tumors of the appendix, it is important to report all findings in an effort to improve our understanding and treatment approaches of this rare disease.
RESUMO
BACKGROUND: The intragastric balloon (IGB) is an adjunctive treatment for obesity. This meta-analysis aimed to evaluate the efficacy and safety of IGB treatment by reviewing randomized controlled trials (RCTs). METHODS: A total of 20 RCTs involving 1195 patients were identified. Weight loss results before and after 3 months were analyzed separately. The weight loss results of patients with and without IGB treatment were compared. RESULTS: Our meta-analysis calculated the following significant effect sizes: 1.59 and 1.34 kg/m2 for overall and 3-month BMI loss, respectively; 14.25 and 11.16 % for overall and >3-month percentage of excess weight loss, respectively; 4.6 and 4.77 kg for overall and 3-month weight loss, respectively; and 2.81, 1.62, and 4.09 % for overall, 3-month, and >3-month percent of weight loss, respectively. A significant effect size was calculated that favored fluid-filled IGBs over air-filled IGBs. Flatulence (8.75 vs. 3.89 %, p = 0.0006), abdominal fullness (6.32 vs. 0.55 %, p = 0.001), abdominal pain (13.86 vs. 7.2 %, p = 0.0001), abdominal discomfort (4.37 vs. 0.55 %, p = 0.006), and gastric ulcer (12.5 vs. 1.2 %, p < 0.0001) were significantly more prevalent among IGB patients than among non-IGB control patients. No mortality was reported from IGB treatment. CONCLUSION: IGB treatment, in addition to lifestyle modification, is an effective short-term modality for weight loss. However, there is not sufficient evidence confirming its safety or long-term efficacy.
