However, and from the beginning of the pandemic, every center attending surgical urgencies had to guarantee the continuous coverage adopting correct measures to maintain the excellence of quality of care.

Nonoperative management of perforated acute diverticulitis with extraluminal air: results and risk factors of failure.

Aim: The aim of this study was to analyze the results of nonoperative management of patients with perforated acute diverticulitis with extraluminal air and to identify risk factors that may lead to failure and necessity of surgery.

Methods: Methods included observational retrospective cohort study of patients between 2010 and 2015 with diagnosis of diverticulitis with extraluminal air and with nonoperative management initial. Patient demographics, clinical, and analytical data were collected, as were data related with computed tomography.

Acute abdomen in patients with systemic lupus erythematosus and antiphospholipid syndrome. Importance of early diagnosis and treatment.

Systemic lupus erithematosus (SLE) is an autoimmune disease with multiorgan involvement caused principally by vasculitis of small vessels. The gastrointestinal tract is one of the most frequently affected by SLE, with abdominal pain as the most common symptom. An early diagnosis and treatment of lupus enteritis is essential to avoid complications like hemorrhage or perforation, with up to 50 % of mortality rate.

Acute necrotizing pancreatitis: Surgical indications and technical procedures.

Necrosis of pancreatic parenchyma or extrapancreatic tissues is present in 10%-20% of patients with acute pancreatitis, defining the necrotizing presentation frequently associated with high morbidity and mortality rates. During the initial phase of acute necrotizing pancreatitis the most important pillars of medical treatment are fluid resuscitation, early enteral nutrition, endoscopic retrograde colangiopancreatography if associated cholangitis and intensive care unit support. When infection of pancreatic or extrapancreatic necrosis occurs, surgical approach constitutes the most accepted therapeutic option.

[Radiological support for diagnosis of acute appendicitis: use, effectiveness and clinical repercussions].

Objective: The aim of this study is to analyze the increasing need of radiological support in the diagnosis of acute appendicitis (AA), the clinical repercussions associated, and the parameters of diagnostic accuracy of ultrasound and computed tomography (CT) scan for AA.

Material And Methods: Observational and analytical study. Cohort, patients operated on for suspected AA at a tertiary referral hospital.

[Post-appendectomy surgical site infection: overall rate and type according to open/laparoscopic approach].

Objective: To compare the incidence and profile of surgical site infection (SSI) after laparoscopic (LA) or open (OA) appendicectomy.

Material And Method: Observational and analytical study was conducted on patients older than 14years-old with suspected acute appendicitis operated on within a 4-year period (2007-2010) at a third level hospital (n=868). They were divided in two groups according to the type of appendicectomy (LA, study group, 135; OA, control group, 733).

Posterior approach (Kraske procedure) for surgical treatment of presacral tumors.

Presacral tumors are rare, but can comprise a great variety of histological types. Congenital tumors are the most common. Once the diagnosis is established, surgical resection is essential because of the potential for malignancy or infection.
