    (SOC CIRUJANOS CHILE, 2012) Caselli M, Gino; Inostroza L, Gonzalo; Silva C, Cristobal; Urrejola S, Gonzalo; Zuniga D, Alvaro; Molina P, Maria Elena; Bellolio R, Felipe; Pinedo M, George
    Background: The usual surgical management of acute diverticulitis is Hartmann operation that is associated with high rates of complications and mortality. Recently, less invasive procedures, that avoid ostomies have been proposed as treatment. Aim: To analyze the results of laparoscopic peritoneal lavage in patients with acute diverticulitis. Material and Methods: Prospective analysis of seven patients age 25 to 61 years (four males) admitted for a first episode of acute diverticulitis classified as Hinchey II or III, in whom a percutaneous drainage of collections was not possible. All were subjected to a laparoscopic peritoneal lavage and debridement. Results: The mean body mass index of patients was 30.3 kg/m(2). Operative time was 55 +/- 28 min and there was no need for ostomies or conversion to open surgery. Two patients had complications. One required a percutaneous drainage of a collection and other required an open surgical procedure for peritoneal lavage. Patients stayed with nil per os for 2 +/- 1 days, required antimicrobials for 14 +/- 4 days and stayed in the hospital for 8 +/- 4 days. Conclusions: Laparoscopic peritoneal lavage is a good alternative surgical procedure for the treatment of acute diverticulitis.

    Natural Hazards in Patrimonial Geosites on the Southern Coast of Atacama
    (PONTIFICA UNIV CATOLICA CHILE, INST GEOGRAFIA, 2010) Castro A, Consuelo; Marquardt R, Carlos; Zuniga D, Alvaro
    The southern coast of Atacama Desert, between the city of Chanaral (26 degrees 20' S) and the Copiapo River, (27 degrees 19' S), presents a great diversity of shapes, types of rocks and fossil deposits. Some of the most incredible Geosites can be found on this coastal zone, which are significant for geosciences, culture and nature adventure tourism. Geosites are an important patrimonial resource that gives potential for conservation and support for sustainable tourism activities in the III Region of the country. The arid morphodynamic coastal zone becomes vulnerable by the occurrence of natural hazards such as seismicity, tsunamis, mass flows and alluvial flows. The natural and hazardous phenomenon of the southern coast of Atacama are characterized and analyzed, determining its effects on Geosites, this contributes to create a base of scientific information for management planning and for sustainable proposals for these areas, anticipating its effects on inhabitants, their goods and the existing infrastructure, as well as for the increasing number of tourists attracted by the nature of the coastal desert.
