The use of laparoscopic as a diagnostic instrument in blunt penetrating abdominal traumas was first proposed by some authors in the 70s. The introduction of sophisticated instrumental tests, such as CAT and echotomography (ETG), confined this method to narrow diagnostic field which was gradually less frequently used. The lively interest expressed by the surgical world and the enormous spread of laparoscopy after the end of the 80s, following the introduction of laparoscopic cholecystectomy, has prompted the renewed use of the laparoscopic technique also in those subjects with blunt abdominal trauma. Over the past 12 months the authors have used laparoscopy in 8 subjects with hemoperitoneum secondary to contusive abdominal trauma in hemodynamically stable conditions, in which instrumental test (CAT and ETG) and peritoneal lavage were positive for the presence of hematic effusion. The use of laparoscopy in 7 patients allowed a wait-and-see approach to be adopted, thus eliminating the need for explorative laparotomy. It was only necessary to proceed with laparotomy in one patient to control bleeding from a major splenic lesion.

As well as being related to the spread of the tumour, cancer patients present a state of immunodeficiency which is linked to age, malnutrition which is often present, particular in cases of cancer of the gastroenteric tract, surgery and the possibility of associated chemo- or radiotherapy. The authors studied two groups of 25 patients with colorectal cancer. In addition to antibiotic prophylaxis, group A received immunostimulating therapy with thymopentin-TP5. Group B was treated with antibiotic therapy alone. Cell-mediated immunity was checked preoperatively and after 15 days on the basis of skin reaction to 7 booster antigens (Multitest-IMC). Strictly surgical infective complications were more frequent in group B patients (28.1%) receiving antibiotic treatment alone compared to subjects in group A (21.6%). Infections in a non-surgical site were more than double in the absence of perioperative immune therapy. Of the 25 patients examined in group A, 3-4 postoperative infections and as many long-distance infections were reported, all of which resolved without sequelae within a few days. There was a greater and faster recovery of body weight in those subjects receiving thymopentin treatment in addition to antibiotic therapy. In colorectal cancer surgery antibiotic prophylaxis alone is without doubt a valid surgical antisepsis but, above all in hypoergic patients, it is significantly enhanced by perioperative treatment with thymopentin. This association reduces both postoperative infectious complications, in particular postoperative abdominal abscess, and infections in other areas, such as respiratory complications.

A case of gallbladder torsion complicated by sigmoid volvulus and sub-torsion of the ileus is reported because of the difficulty of diagnosis, conditioned by polymorphic symptomatology, the expression of a variety of causes and contributing causes that play an important role in the greater or less onset of dramatic symptomatology, and because of the rarity of the pathology.
