[The hyperfunctional thyroid nodule].

Authors report their experience of 22 years regarding 284 patients with hyperfunctional thyroidal nodules (279 operated), representing 12.4% of the 2,289 cases of thyroidal (875 hyperthyroid) diseases treated during this period. The diagnosis was established on the basis of the confrontation of the anamnestic symptomatology and of that found at the clinical examination--which confirmed the pure character of thyrotoxicosis by showing the presence of a thyroidal nodule--with the study of the global glandular function and the scintigram, completed with dynamic tests. Among the typical clinical and scintigraphic, usually severe, forms (with cardiothyreosis) may be distinguished asymptomatic or atypical forms (with dissociated or intermittent manifestations). The treatment of the toxic thyroidal adenoma is surgical, except some contraindications of a general order. The surgical treatment is aimed at achieving the permanent cure of the disease, without sequelae or functional and/or morphological relapses. The subtotal lobectomy (210 cases) is preferred as an exeresis procedure to the enucleoresection (45 cases). In most operated cases (93%) the immediate clinical and biological results were favourable.

[Prevention and therapy of postoperative thyrotoxic crisis].

Out of a group of 361 patients with various anatomo-clinical forms of hyperthyroidia--of which 328 had underwent surgery--hospitalized in the Surgical Clinic from Jassy between 1965 and 1974, a total of 17 observations are analised, from the clinical and the therapeutical viewpoint, that showed postoperative thyreotoxicosis crisis. The fact is stressed that the prophylaxis of the crisis is dominated by the principle that no case of hyperthyroidia should be operated on before it has been perfectly balanced from the endocrinological viewpoint. The complex treatment of the cases that are presented included a symptomatic component to which were associated oxygen therapy, tonics, vitamins, hepatotrop preparations, eventually antibiotics. The results obtained--complete recovery in all the cases--can be compared with the best from the literature.

[Unusual localizations of hydatid cysts].

In a total of 448 hydatic cysts that have been treated in the I-st Surgery Clinic of Jassy between 1947 and 1977 rare localizations were noted in 61 cases. Of these 47 were primary echinococcoses and 14 were secondary. The clinical and therapeutic aspects are discussed for each particular localization: the splenic localization was encountered in 16 cases, the peritoneal one in 10 cases, the diaphragmatic in 6 cases. There were also 2 renal localizations, 3 retro-peritoneal ones, 3 ovarian and salpyngean localizations, 3 thyroid, 7 endo-thoracic but extra-pulmonary, 5 muscular and 6 subcutaneous localizations. Radical surgery had immediate and late results that were quite satisfactory. No deaths or recidives were noted.

[The value and limits of subtotal gastrectomy in gastric cancer].

In the interval 1970-1988, in 321 of 670 patients with gastric neoplasm admitted to the 1st Surgical Clinic of Iaşi a subtotal gastrectomy was performed. Most patients were males (68.9%), more commonly aged between 50 and 70 years and in advanced evolutive stages. The gastric neoplasm were sited in order of frequency in the antrum (46.9%), body of the stomach (34.6%), eso-cardio-tuberosity (11.5%), linitis (4%), gastric stump and malignant ulcer (3%). Surgery was possible in only 59% of the cases (25% curative and 34.1% palliative). The surgical technique and its difficulties are detailed. In the 321 subtotal gastric resections 20 complications, 4 deaths (1.2%) and 20% survivals over 5 years were recorded. It is concluded that radioendoscopic and microscopic investigations, with their possibility of an early diagnosis, may cause a limitation of the indications of total gastric resection in the treatment of gastric neoplasm in favour a subtotal resection, more satisfactory from the functional viewpoint.

[A rare neurogenic tumor with thoracic growth].

Of 70 operated mediastinal tumors, 15 were neurogenic tumors, one of them clepsydra-shaped, which manifested from the very beginning with spastic paraparesis of the legs. The treatment consisted in a two-steps surgery, the first at the Neurosurgical Clinical of Iaşi (laminectomy and ablation of the rachidian tumor) and the second one, one month later, at the I-st Surgical Clinic of Iaşi (excision of mediastinal tumor and parenchymal bridge within the conjugation hole). The microscopic examination confirmed the diagnosis of neurinoma (schwannoma) Antoni A and B with haemorrhagic areas. Examined at one year interval, the patient was clinically cured with normal thoracic aspect. The clinical peculiarities and therapeutical possibilities of the clepsydra-shaped neurogenic mediastinal tumors are detailed.

[Cholecystosis, the diagnostic and treatment problems].

In the interval 1981-1989 at the Ist Clinic of Surgery of Iaşi 230 cases of chronic cholecystitis were admitted and operated upon (cholesterolosis--24 cases, dysmorphosis--84 cases, dysplasia--22 cases). Most cases had a morphologic--dysmetabolic substrate--strawberry gallbladder, alone or associated with other lesions (lithiasis, cirrhosis, pancreatitis), rare cases being also found (porcelain gallbladder--1 case, calcium bile--2 cases, gallbladder diverticulosis--3 cases, longitudinal complete obstruction of cystic duct by gallstone--2 cases). This condition is more frequent in women in the 3rd dad 4th decade, the symptoms being discrete, uncharacteristic, but persistent. The diagnosis is based on duodenal catheterization, cholecysto-cholangiography and ultrasonography, the intraoperative and histo-pathologic confirmations being required. The increasing frequency of chronic cholecystitis makes necessary a more minute diagnosis and exigent surgical indication, pledges for long-term favourable results.

Adult

[Differentiated thyroid cancer].

In the interval 1979-1988, out of 1070 operated goiters 77 malignant thyroid tumors were recorded, 60 of them being differentiated: papillary--32 (53.4%), vesicular--12 (20%), mixed forms--16 (26.7%). The differentiated thyroid carcinomas had peculiar clinical biological and prognostic features and were framed: stage I--60%, stage II--23.4% and state III-IV--16.6%. Only 15 cases presented lymph node metastases. In 16 cases the thyroid tumor was associated with another thyropathy: Hashimoto's thyroiditis--5 cases, Basedow's disease--1 case. The surgical intervention was performed in two times: first total lobectomy or total lobo-isthmectomy [correction of lobioistectomy] with contralateral subtotal exeresis, then total thyroidectomy. It is insisted upon a careful surveillance of postoperative evolution (clinical, biological, scintigraphy) in order to detect the recurrence and apply a proper treatment.

[The "cold" thyroid nodule].

The main problem posed by an (apparent) solitary thyroid nodule is cancer identification, present in about 10% of the nodules excised surgically. This percent might increase to 25-30% in the cold scintigraphic nodules. Therefore, a combination of all the methods for nodule assessment is necessary: anamnesis, physical examination, functional tests, therapeutic test with tyrosine and thyroid imaging, but mainly the intensive active exploration including puncture-biopsy with a fine needle and exeresis with extemporaneous and paraffin morphological checking. Starting from a two decades' experience of a group of endocrinologists, surgeons, anatomo-pathologists and specialists in nuclear medicine, in 2,289 thyropathies operated--of whom 1691 (poly)nodular goitres and 1,190 non-capturing nodules--the authors suggest an investigation algorithm for achieving a differentiated surgery in terms of the pre- and intraoperative morphological findings. This attitude permitted both the improvement of the surgeries of thyroid cancers and the exeresis of benign nodules under low-risk surgical conditions or avoidance of a "non-necessary" surgery.

Biopsy

[Tumors of the small intestine].

On the basis of 20 observations of tumours of the small bowel a series of diagnostic, therapeutic and prognosis of these lesions are discussed. Malignant tumours of the small bowel (10 adenocarcinomas and 2 sarcomas in the present statistics) represent 1,9 per cent of the total number of malignant tumours of the small bowel. The patients were hospitalized following an acute complication occlusion, haemorrhage, perforation). Four of the patients benefited from a curative treatment, in 5 only a derivation was possible, and in 9 only exploratory laparotomy and bioptic sampling. Eight of the tumours were benign and consisted in : 3 fibromas; 2 neurogenic tumours; 2 adenomatous polyps, and one lipoma. All were discovered in the course of emergency surgery for occluding syndrome or haemorrhage, and benefited from a radical treatment. Two deaths were recorded in the entire series (one following embolism in the 10-th day after surgery and another in the 3-rd day with occluding shock). Both patients were in a condition of severe hydroelectrolytic imbalance.
