The aim of the study was to investigate major vascular injury during laparoscopic cholecystectomy, which is a rare but potentially lethal complication if not recognized and treated swiftly, usually secondary to placement of the Veress needle or trocar. We report on our experience with a 35-year-old woman presenting an aortic laceration of the anterior wall and a puncture wound penetrating the anterior wall of the inferior vena cava. Repair of the injuries was done using a 5-0 Prolene suture mounted on pledgets. In addition, it was necessary to suture three mesenteric vascular injuries in the posterior peritoneum with Vicryl 2-0. The estimated blood loss was 1300 cc. The patient did well and was discharged on postoperative day 13. The distal abdominal aorta, inferior vena cava and large pelvic vessels are particularly prone to injury during laparoscopic cholecystectomy. In most cases, the vascular defect can be closed by direct suturing. Rarely is it necessary to reconstruct the injured vessel with an alloplastic prosthetic patch or a prosthetic implant.

Of a total of 5,700 surgical procedures on the neck performed at our Institution between 1984 and 1995, 13 operations (0.22%) have been done on 11 patients with 16 cervical paragangliomas. A woman underwent resection of synchronous bilateral carotid body tumours and of an intravagal paraganglioma. Ten years later, after preoperative angiographic embolization, she underwent resection of a paraganglioma of the left hypoglossal nerve. Her sister, at age 21, underwent resection of a carotid body tumour and, respectively 19 and 20 years later, of a right and left intravagal paraganglioma. An interposition graft for replacement of the carotid bifurcation was necessary in one patient only. During resection of a left carotid body tumour, acute hypotension occurred resulting in an ischemic lesion of the right temporal lobe. Postoperatively, she also complained of respiratory distress that responded to medical therapy with difficulty. The related neurologic symptoms completely resolved three months after surgery. The operation for a paraganglioma of the left hypoglossal nerve resulted in a temporary motor deficit of the tongue and in permanent considerable difficulty in swallowing. Unilateral recurrent nerve palsy occurred in two patients. No patients during the postoperative follow-up showed signs of local recurrence or metastatic disease. In conclusion, surgery is an effective treatment for cervical paraganglioma, but because of the high surgical complication rate, an experienced and skilled surgeon is called on to optimize outcome. An adequate perioperative care is advisable.

The authors describe a rare case of spontaneous haemothorax in a 19-year-old woman suffering from beta-thalassaemia major which developed as a result of extramedullary haematopoiesis. In intrathoracic disorders of obscure origin they recommend therefore to make first a cytological examination of the punctate to prevent unnecessary surgery.

The Authors, after an accurate review of the Literature, report their experience in the combined management of aorto-iliac and biliary lesions. Surgical priorities are well specified in order to reduce the possibility of bacterial contamination of the vascular prosthesis.

A preliminary study has been carried out on 10 patients suffering from cancer of the colon and rectum, all subjected to radical surgery. The clinical effectiveness of two alternative techniques of postoperative artificial nutrition, EPEN and TPN, are compared. The results confirm that enteral nutrition is technically applicable and well tolerated in the immediate post-operative period in these patients; it also presents a lower cost, it is more manageable and present a lower incidence of complications compared to TPN while offering similar metabolic and nutritional results.

Fine needle aspiration cytology (FNAC) is the more accurate diagnostic method for cervical lymph node (CLN) metastasis from differentiated thyroid cancers (DTC). However, FNAC diagnosis of cystic CLN is, in most cases, uninformative due to inadequate cellularity. Recently, thyroglobulin (Tg) detection in FNAC needle washout fluid has been shown to improve the diagnostic accuracy of FNAC, and its routine association with cytology is recommended. We here describe the case of a 20 yr old girl complaining of the recent appearance of palpable non-painful laterocervical nodes in the neck. Ultrasound examination revealed the presence of 3 cystic CLNs and 2 mixed thyroid nodules, with the larger one showing irregular margins. On the latter, and on 2 larger CLNs, FNAC was performed, and both Tg protein and mRNA were determined in the needle washout. The cytological analysis was not diagnostic for the two CLNs, while that of the thyroid nodule reported the presence of colloid and groups of thyrocytes with normal morphology. Both CLNs showed, however, high levels of Tg protein and were positive for Tg mRNA, suggestive of metastatic DTC. Based on these findings, the FNAC analysis was performed on the second smaller thyroid nodule suggesting (Tir4) the presence of PTC. The patient was then subjected to total thyroidectomy with lymph nodes resection of the central and homolateral compartments. The histological diagnosis confirmed the presence of a PTC in the small nodule and metastatic lymph nodes. In conclusion, this case confirms that the cytological diagnosis of cystic lymph nodes is challenging, and that the measurement of Tg protein and/or mRNA in the needle washout may overcome this limitation.
