BACKGROUND: Although laparoscopic cholecystectomy (LC) results in less pain then open cholecystectomy, it is not a pain-free procedure. The aim of this study was to test a new method of preemptive analgesia. METHODS: By simple randomization 60 patients were assigned to two groups (30 in each group). Group A, the placebo group, received 200 ml of 0.9% saline, and group B received 5 mg/kg of a local anesthetic solution (ropivacaine) in 200 ml of 0.9% saline. Local anesthetic or placebo solution were administer before creation of the pneumoperitoneum. RESULTS: Pain intensity, as rated by visual analog and verbal rating scales, and stress response data were significantly less in the group receiving ropivacaine than in the placebo group. No patients in treatment group received an additional dose of analgesic, whereas two patients in placebo group needed an additional analgesic. CONCLUSIONS: Our results support the clinical validity of preemptive analgesia, but the timing of intraperitoneal administration of local anesthetic is very important. Only application before creation of the pneumoperitoneum may preempt every neuronal central sensitization.

Single pulmonary nodules: localization with intrathoracoscopic ultrasound -- a prospective study.

This prospective study, based on 13 patients with single pulmonary nodules of width between 10 and 30 mm, was performed to verify the utility of intrathoracoscopic ultrasound to localize the single pulmonary nodule. In all 13 cases the ultrasound examination was able to localize the position of nodules, but the homogeneous hypoechoic pattern of nodules observed in ten of 13 cases did not prove whether the lesion was benign or malign. In conclusion, we can confirm that intrathoracoscopic ultrasound examination is a safe, risk-free and less expensive method of localizing the single pulmonary nodules.

Significance of a single pulmonary nodule in patients with previous history of malignancy.

OBJECTIVES: To determine the diagnosis, treatment and follow-up in patients with a solitary lung nodule and a previous primary extrapulmonary neoplasm. METHODS: The authors evaluated the charts of 45 patients with an extrapulmonary malignant neoplasm and a solitary pulmonary nodule. The histologic characteristics of the nodule were correlated with those of the extrapulmonary neoplasm. RESULTS: The histology of the nodule was not known preoperatively in 43 cases (93.5%); in the remaining three cases cytologic examination had shown the presence of atypical cells. The majority of pulmonary lesions (73.9%) were found during the follow-up of the previous tumour, but a significant percentage of nodules (17.4%) were found incidentally. Pre- or intraoperative localisation of the nodule was done in 19 cases (41.3%), and was successful in nine cases (47.4%). Thoracoscopy was performed in 44 patients (95.6%). The coincidence between the pathology of the previous tumour and that of the nodule was 41.3% (19/46). The coincidence rate was 100% for the tumours of ovary, prostate, and sarcomas. CONCLUSIONS: The advent of minimally invasive surgical techniques has made a definitive diagnosis likely, providing also therapy with a less painful engagement for the patient and a less cost for the community.

Impact of laparoscopy and ultrasonography in gastrointestinal malignancies.

BACKGROUND/AIMS: An adequate preoperative disease staging is highly required before surgical treatment, even in gastrointestinal malignancies. Our study wants to give a contribution in order to define echolaparoscopy weight in gastrointestinal tumors and its impact in surgical therapy. METHODOLOGY: 33 patients were affected by pancreas, 22 by stomach, 16 by extrahepatic biliary tract and 18 by liver cancers; every patient was considered worthy of radical or palliative surgery according to preoperative staging (thorax-abdominal CT and percutaneous ultrasonography). Paired sample t-tests were used to analyze the results of each methodical and probability values of less than 0.05 were considered significant. RESULTS: Preoperative instrumental examinations gave correct evaluations only in 44 of 89 cases (49%) while echolaparoscopic gave correct evaluations in 82 on 89 cases (92%) (P<0.05). So after echolaparoscopic in only 7 cases we performed an explorative laparotomy. CONCLUSIONS: Laparoscopy and ultrasound impact on therapy is worthy of attention. It seems to be able to give advantages in staging gastrointestinal malignancies, except for pancreas cancers, in which some limits and negative aspects have been demonstrated, regarding the possibility of giving correct diagnosis of portal axis infiltration.
