Minimally Invasive Pericranial Flap for Reconstruction after Endonasal Endoscopic Surgery of 30 Consecutive Patients

引用

International Journal of Otolaryngology and Head & Neck Surgery 2018年第4期7卷 199-208页

作者： Joel Caballero-García Iosmill morales Pérez Adolfo Michel Giol álvarez Nélido Gonzáles Fernández Bismark Rafael Barcia Sánchez Roxana Bethzave Ortega Pineda National Institute of Oncology and Radiobiology Havana Cuba juan manuel Márquez Pediatric Hospital Havana Cuba

Objectives/Hypothesis: The introduction of intranasal pedicled flaps has reduced the incidence of postoperative cerebrospinal fluid (CSF) leaks to less than 5%. Nevertheless, in malignant tumors those flaps are not always available because of nasal septum invasion. Minimally invasive pericranial flaps (PCF) are associated with minimal adverse effects and good cosmetic appearance. In spite of that, there are only a few reports of this reconstructive technic limited to short surgical series and radio-anatomical analysis. Clinical results of a surgical cohort are presented. Study Design: Cohort prospective study. Methods: Clinical data, including age, gender, stage, histopathological findings, rate of complications and appearance of PCF at fifth day and two months postoperative were recorded. Postoperative morbidities were recorded as wound abnormalities, nasosinusal, orbital and central nervous system complications. Chi-squared test was used to correlate qualitative variables and Student-t-test to correlated qualitative and quantitative variables. Items were considered statistically significant with a p value of less than 0.05 (confidence Interval of 95%). Results: Thirty patients (18 males and 12 females) were registered. Mean age was 51.5 years ± 23.0 and range between 20 and 71 years. Most common histologic subtypes were adenocarcinoma, epidermoid carcinoma and squamous cell carcinoma. Complete resection of the tumor was achieved in all patients including surgical margins. Length of the PCF varies between 9.9 cm and 13.9 cm with a mean of 11.8 cm. There was an association between length of the flaps and the covering structure with the nose apex relation. None patient experienced postoperative cerebrospinal fluid (CSF) leak, frontal sinusitis or other complications. Conclusions: Minimally invasive PCF constitute a good and inexpensive reconstructive option in patients with malignant anterior cranial base tumors in whose nasoseptal flap was not a feasible option.

Role of double-balloon enteroscopy in malignant small bowel tumors

AIM: To assess the double-balloon enteroscopy(DBE) role in malignant small bowel tumors(MSBT).METHODS: This is a retrospective descriptive study performed in a single center. All consecutive patients who underwent a DBE with final diagnosis of a malignant neoplasm from 2004 to 2014 in our referral center were included. Patient demographic and clinical pathological characteristics were recorded and reviewed. MSBT diagnosis was achieved either by DBE directed biopsy with multiple tissue sampling, endoscopic findings or histological analysis of surgical specimen. We have analyzed double-balloon enteroscopy impact in outcome and clinical course of these patients. RESULTS: Of 627 patients, 28(4.5%)(mean age = 60 ± 17.3 years) underwent 30 procedures(25 anterograde, 5 retrograde) and were diagnosed of a malignant tumor. Patients presented with obscure gastrointestinal bleeding(n = 19, 67.9%), occlusion syndrome(n = 7, 25%) and diarrhea(n = 1, 3.6%). They were diagnosed by DBE biopsy(n = 18, 64.3%), histological analysis of surgical specimen(n = 7, 25%) and unequivocal endoscopic findings(n = 2, 7.1%). Gastrointestinal stromal tumor(n = 8, 28.6%), adenocarcinoma(n = 7, 25%), lymphoma(n = 4, 14.3%), neuroendocrine tumor(n = 4, 14.3%), metastatic(n = 3, 10.7%) and Kaposi sarcoma(n = 1, 3.6%) were identified. DBE modified outcome in 7 cases(25%), delaying or avoiding emergency surgery(n = 3), modifying surgery approach(n = 2) and indicating emergency SB partial resection instead of elective approach(n = 2).CONCLUSION: DBE may be critical in the management of MSBT providing additional information that may be decisive in the clinical course of these patients.
