[When a peritonitis does not seems like a peritonitis].

Acute pancreatitis should be considered in the differential diagnosis of acute abdominal pain. Although its incidence is low, it has increased in the last years; therefore, an accurate diagnosis is necessary to avoid inappropriate surgeries. The aim of this study is to describe acute pancreatitis in the context of acute abdominal pain, which suggests appendicitis.

[Benefits of epidural analgesia in major neonatal surgery].

The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology.

[Using Kehr's tube in complex anastomoses].

Objective: To present a new technique using the Kehr's T tube (KT) in complex intestinal anastomoses.

Materials And Methods: Restrospective descriptive analysis of 8 patients intervened from 2007 to 2011. We performed intestinal anastomoses guided by a KT in 7 patients with intestinal atresia (yeyunal n = 5, ileal n = 1, duodenal n = 1), and in 1 patient with yeyunal stenosis associated with gastroschisis.

[Relation between packed red blood cell transfusion and severity of necrotizing enterocolitis in premature infants].

Objective: It has been proposed recently that red blood cell transfusions (RBCT) might increase severity in infants with necrotizing enterocolitis (NEC). We intend to study if patients who have received red blood transfusions before the onset of NEC develop more severe forms of this entity.

Methods: A retrospective study was carried out including prematures with NEC.

Could clinical scores guide the surgical treatment of necrotizing enterocolitis?

Purpose: Test the diagnostic reliability of the score for neonatal acute physiology-perinatal extension-II (SNAPPE-II) and the metabolic derangement acuity score (MDAS) as predictors of surgery in patients with necrotizing enterocolitis (NEC).

Methods: The SNAPPE-II and the MDAS were applied to 99 patients with NEC. Both the scores were calculated at the moment of diagnosis (T(0)) and when surgical assessment was required (T(1)).
