Facial nerve function after parotidectomy for neoplasms with deep localization.

PURPOSE: To determine whether the deep location of a parotid gland neoplasm is specific risk factor for facial nerve paralysis after parotidectomy. METHODS: We retrospectively reviewed 88 patients, including 59 with a benign superficial neoplasm of the parotid treated by superficial parotidectomy (group 1); 5 with a benign deep neoplasm treated by total parotidectomy (group 2); 20 with a malignant superficial neoplasm treated by total parotidectomy (group 3); and 4 with a malignant deep neoplasm treated by total parotidectomy (group 4). RESULTS: Temporary facial nerve paralysis developed in 10.3%, 20%, 10%, and 50% of groups, 1, 2, 3, and 4, respectively. Permanent facial nerve paralysis developed in 0%, 0%, 10% and 50% of groups 1, 2, 3, and 4, respectively. CONCLUSION: The risk factor associated with nerve damage resulting from surgery for parotid neoplasms were malignancy and deep localization. However, the deep location of a benign tumor was not a major risk factor for permanent paralysis.

Microsurgical distal sympathectomy in chronic vasospastic syndromes of the hand.

The authors propose a microsurgical technique to treat upper limb chronic digital ischemia that is resistant to medical therapy. The adventitiectomy technique on digital arteries is used here to remove the fibrous tissue and the vasoconstrictor sympathetic nervous fibers contained in it. This operation is a valid alternative to traditional proximal sympathectomy.

[Lymphectomy for well differentiated or "aggressive" thyroid malignancies. Indications, complications and results of our experience]. / La linfectomia per neoplasie maligne ben differenziate o "aggressive" della tiroide. Indicazioni, complicanze e risultati nella nostra esperienza.

The aim of this retrospective study was to assess the role of lymphectomy in the treatment of well differentiated and aggressive carcinomas of the thyroid gland. From 1987 to 2002, 231 patients were operated on in our Division; 97 were male (42%) and 134 female (58%), with a mean age of 48 years (range 17-45). One hundred and ninety-four patients had well differentiated thyroid carcinomas, and 37 aggressive thyroid cancer. We performed a follow-up on 171/231 patients (74%) who underwent surgery from 1997 to 1998. Among the 143 patients with well differentiated neoplasms, 93 were treated with total thyroidectomy (65%), and 50 with total thyroidectomy with simultaneous or subsequent lymphectomy (35%); 92 patients underwent postsurgical radiomethabolic therapy (64%). Two patients developed non-functional metastases and died because of disease progression. Of the 28 patients affected by aggressive tumours, 8 underwent total thyroidectomy (29%) and 20 total thyroidectomy with simultaneous or subsequent central lymphectomy (71 %). All 28 patients with aggressive malignancies underwent postsurgical radiomethabolic therapy (100%). Three patients developed diffuse non-functional metastases and died because of disease progression.

[Pancreaticojejunostomy by simple introduction after pancreaticoduodenectomy]. / Pancreatodigiunostomia per introduzione semplice dopo duodenocefalopancreatectomia.

The method which most surgeons still prefer in the treatment of the pancreatic stump after pancreaticoduodenectomy is pancreaticojejunostomy. In this article, we describe our preliminary experience with a fast, effective method, consisting in an end-to-end pancreaticojejunostomy by simple introduction, in 11 cases operated on without morbidity or mortality. From 1998 to 2002, 11 patients with pancreatic head or distal bile duct neoplasms underwent pancreaticoduodenectomy. After removal of the specimen, the residual pancreatic stump was prepared towards the left for about two centimetres, mobilizing the posterior surface from the porto-meseraic axis. A single layer of interrupted suture, consisting only in two posterior stitches, was enough in all cases; each stitch was done taking the stump full-thickness at about one centimetre from the transection margin (so as to introduce a corresponding portion of parenchyma into the jejunal lumen), and from the superior and inferior margin, respectively, of the pancreas. On the intestinal side, the stitches were passed full-thickness from the inner surface to the outside, 6 to 7 millimetres from the transection margin. After introducing the stump completely into the intestinal lumen, three anterior stitches were always done and knotted between the pancreatic capsule and the jejunum. All the anastomoses proved to be perfectly sealed.
