Recurrent gallstone ileus: case report and literature review.

The gallstone ileus is a rare complication of cholelithiasis and it represents the 1-4% of small intestinal mechanical obstruction. Gallstone is generally wedged in the terminal ileum, even if unusual locations have been described. The literature reports a very high morbidity and mortality, often because misdiagnosis or delayed diagnosis. There is no unique opinion in literature about the choice between one-stage and two-stage surgery. We report a clinical case that summarizes the diagnostic and therapeutic difficulties of gallstone ileus.

[Treatment of mild malnutrition and reduction of morbidity in major abdominal surgery: randomized trial on 153 patients]. / Trattamento della malnutrizione lieve e riduzione delle compli- canze in chirurgia addominale maggiore: studio randomizzato su 153 pazienti.

OBJECTIVES: Severe malnutrition (defined as weight loss more than 10% in a period of six months) is considered an important risk factor in major abdominal surgery, because of a higher post-operative mortality and morbidity. The aim of our study is to assess the role of mild malnutrition (weight loss low than 10% in a period of six months) as a risk factor in major abdominal surgery and to evaluate the efficacy of therapy in order to improve outcomes in terms of in-hospital mortality, length of hospital stay and post-operative complications. Moreover, we evaluated serum albuminemia and lymphocyte count, important nutritional index, as predictive risk factors. MATERIALS AND METHODS: We performed a randomized prospective trial, and admitted in our institution 153 adult patients, 43 with mild malnutrition and 110 without. The malnourished patients were randomized in two groups: the first one received oral immunonutrition (Impact Oral) for 7-10 days before surgery (22 pz), the second one received no nutritional support. RESULTS: We observed a higher number of complications in the non-treated malnourished patients (57%) versus both the treated malnourished patients (13.6%) and the normal group (19%) (p<0.001). Increased morbidity was observed in patients with serum albuminemia <2.8 gr/dl (69.2%) and with lymphocyte count <1.500 mm3 (57%). CONCLUSIONS: Nutritional enriched support demonstrated his efficacy in reducing morbidity, and length of hospital stay. Pre-operative oral immunonutrition might be suggested and established in all the patients with mild malnutrition that will be operated on major abdominal surgery.
