Gallbladder injuries due to blunt abdominal trauma: report on five cases and review of the literature.

Gallbladder lesions by blunt abdominal trauma are rare, due to the organ's anatomical particularities. Diagnosis is difficult, and it generally occurs during surgery. The trauma is usually associated with other lesions and is related to very serious traumas or to deceleration. Due to the scarcity of publications on this topic and to its reduced incidence, we present here a report of five patients who had suffered blunt abdominal trauma with gallbladder lesion and who were attended at the General Hospital (of the University of São Paulo Medical School) Emergency Service between 1986 and 1991. Furthermore, we analyze the incidence of this trauma, presence of associated lesion, treatment, morbidity and mortality of the patients, as well as a review of the literature.

[Comparative analysis of the diagnostic value of ultrasonography and laparoscopy in acute abdomen].

Patients with traumatic or non-traumatic acute abdomen, often exhibit difficulties in the assessment of the real intra-abdominal visceral compromise. This study intends to compare laparoscopy and ultrasonography in patients with non-traumatic or traumatic acute abdomen, in whom there is a doubt on the actual visceral compromise. Forty-five patients were studied in this protocol. Both procedures were performed in 28 and in 17 patients with non-traumatic or traumatic acute abdomen, respectively. The laparoscopic examination was shown to be superior to the ultrasound even when one subtracts from the ultrasound data all pathologies that involved bowel transit and the bowel wall such as the acute appendicitis and cases of pelvic inflammatory disease. The laparoscopic and ultrasound accuracy were 97.8% and 53%, respectively.

[Laparoscopy as an auxiliary aid in abdominal emergencies].

The authors present a prospective study of 159 diagnostic laparoscopy performed in patients about whom doubts existed about the actual visceral involvement after initial clinical and laboratory examination by the Surgical Staff on duty. Patients whose initial diagnosis was easily made were immediately submitted to surgery and were not examined by laparoscopy. The laparoscopic exam was shown to be able to diagnose a large number of acute intra-abdominal disturbances, whether or not traumatic, and to be efficient, with accuracy values of 97.4%. The exam also allowed to avoid 44.6% to unnecessary surgical procedures on patients with suspected non-traumatic acute abdomen, and 70% among those with suspicion of traumatic acute abdomen.

Emergency laparoscopy in patients submitted previously to abdominal surgery: a study of 20 cases.

The authors performed 20 laparoscopies in patients previously submitted to abdominal surgery, in whom after clinical evaluation by the medical staff, the existence of intra-abdominal affection was still questioned. In this study group 14 patients exhibited more than 19 days old former abdominal incisions while in six patients they were recent ones. The incisions were median and para-median, McBurney incisions and Pfannenstiel incisions; one patient had been previously submitted to laparoscopy. The laparoscopic findings were hemoperitoneum, encapsulating peritonitis, ascites, subphrenic abscess, acute adnexitis, acute traumatic pancreatitis, genital tuberculosis, acute cholecystitis and one case of peritonitis due to a hollow viscus perforation by a fish bone. In one patient presenting encapsulating peritonitis the laparoscopic examination was complicated by a hollow viscus perforation.

[Diagnostic laparoscopy in nontraumatic acute abdomen].

Laparoscopy was performed in 49 patients admitted to the Emergency Service of Hospital das Clínicas of the Medical School of the University of São Paulo with a possible diagnosis of acute non traumatic abdomen. The procedure was indicated because routine clinical and laboratory investigations had proved inconclusive. Accuracy (96%), sensitivity (97.5%), specificity (89%) and positive (97.5%) and negative (89%) predictive values of laparoscopy were assessed in 41 patients with a clinical suspicion of inflammatory acute abdomen, in 5 with a clinical diagnosis of vascular abdomen, in 1 with a perforative acute abdomen, and in 2 patients to assess the viability of the small bowel after and intestinal resection due to mesenteric ischemia. Laparoscopy proved to be a reliable and simple procedure which facilitated the choice of the best therapeutic alternative in each case. A significant number of unnecessary laparotomies was avoided. No complications imputable to laparoscopy were observed in this series.
