RESUMO
BACKGROUND: Solid pseudopapillary neoplasms (SPN) of the pancreas represents approximately 2% of non-endocrine tumors of the pancreas. It is described in the literature as a rare and predominant tumor in young women. AIM: To report a case series with SPN and analyzing clinical, surgical, anatomopathological characteristics, as well as the prognosis and review of literature. METHODS: Retrospective analysis of patients undergoing surgery, with histological diagnosis of SPN between 1998 and 2018, using standardized and prospectively completed forms, performed at the Surgery Service of the Upper Digestive System at Hospital São Rafael/Rede D'Or in Salvador - BA. Review of literature through a database search in MEDLINE/PubMed of retrospective articles. RESULTS: Fourteen female patients with the average age of 31.6 years (range min-max) were selected. Twelve patients (85.7%) were asymptomatic, being an incidental diagnosis or due to screening for other reasons. One patient had abdominal pain due to gastric compression and another patient had jaundice. The 14 patients were staged with computerized tomography or magnetic resonance imaging. None had evidence of metastasis. In 8 patients (57.1%), the tumor was in the tail and body. The average size was 6.7 cm (range min-18). The type of surgery was according to the anatomical location of the tumor. There was no lymph node involvement. In two cases, vascular resection with the use of a prosthesis was required for reconstruction. The surgical margins were free. In all cases, postoperative immunohistochemistry confirmed that it was a solid pseudo-papillary neoplasia of the pancreas. There has been no disease recurrence in any case so far. CONCLUSION: The tumors had a benign, indolent and histopathological behavior compatible with the literature. Curative surgery is recommended in all cases.
RESUMO
Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.
RESUMO
BACKGROUND: Acute cholecystitis is the major complication of biliary lithiasis, for which laparoscopic treatment has been established as the standard therapy. With longer life expectancy, acute cholecystitis has often been seen in elderly patients (>65 years old) and is often accompanied by comorbity and severe complications. We sought to compare the outcome of laparoscopic treatment for acute cholecystitis with special focus on comparison between elderly and nonelderly patients. METHOD: This study was a prospective analysis of 190 patients who underwent laparoscopic cholecystectomy due to acute cholecystitis or chronic acute cholecystitis, comparing elderly and nonelderly patients. RESULTS: Of 190 patients, 39 (21%) were elderly (>65 years old) and 151 (79%) were not elderly (< or =65 years), with conversion rates of 10.3% and 6.6% (P=0.49), respectively. The incidence of postoperative complications in elderly and nonelderly patients were the following, respectively: atelectasis 5.1% and 2.0% (P=0.27); respiratory infection 5.1% and 2.7% (P=0.6); bile leakage 5.1% and 2.0% (P=0.27), and intraabdominal abscess 1 case (0.7%) and no incidence (P = 1). CONCLUSION: According to our data, laparoscopic cholecystectomy is a safe and efficient procedure for the treatment of acute cholecystitis in patients older than 65 years of age.

BACKGROUND: Randomized studies demonstrate that laparoscopic appendectomy yields better results compared with open techniques. We sought to identify factors that determine an extended hospital stay among patients undergoing laparoscopic appendectomy. METHODS: This was a prospective study including 669 patients undergoing laparoscopic appendectomy. We analyzed variables that can predict the length of hospital stay. RESULTS: Of 669 patients undergoing laparoscopic appendectomy, 141 stayed in the hospital for > or = 5 days (Group 1), and 97 stayed in the hospital for < or = 1 day after surgery (Group 2). The univariate analysis demonstrated that fever (P<0.0001), nausea and vomiting (P=0.060), leukocytosis (P<0.0001), gangrened or perforated intraoperative appearance of the appendix (P<0.0001), and appendix position behind the ileocecal junction (P<0.001) were related to a longer hospital stay. The multivariate analysis through logistical regression showed that the factors independently and significantly associated with an extended hospital stay were presurgical fever, appendix position behind the ileocecal junction, and intraoperative gangrened or perforated appearance of the appendix. CONCLUSION: Fever, appearance, and position of the appendix are factors related to an extended hospital stay.
