[Difficult laparoscopic cholecystectomy].

From 2505 cases operated between 1994-2000, the authors selected a lot of 889 cases of difficult cholecystectomy, which after classical criteria would have been classified as contraindications of laparoscopic procedure. This study analyzed of intraoperative incidents, the conversion rate and particularities of operative tactics and techniques. The lot of patients includes 889 cases of difficult laparoscopic cholecystectomy. The patients were selected according to classical contraindications of laparoscopic cholecystectomy: obesity, liver cirrhosis, previous operated abdomen, severe cardio-pulmonary diseases, ages over 70 years, acute cholecistitis. The rate of intraoperative incidents and accidents was 19.9% (177 cases), in comparison to intraoperative incidents and accidents rate in "easy" laparoscopic chole-cystectomy which was 15.5% (251 cases from 1616 patients). The conversion rate in case of difficult laparoscopic cholecystectomy was 6.1% (55 patients) and 3.2% in the lot of "easy" cholecystectomy. The postoperative morbidity was 6.4% (57 patients) and 5.5% (147 patients) in the lot of "easy cholecystectomy. The postoperative mortality was 0.6% (6 deaths) and 0.3% (5 deaths) in the lot of "easy" cholecystectomy. In this paper are discussed the modalities and the technical particularities of a difficult laparoscopic cholecystectomy, able to lowering the risk of operative incidents and postoperative complications. In conclusion, laparoscopic cholecystectomy can be safely performed to the majority of patients with lithiasic cholecistitis, by an experienced surgical team.

[Surgical treatment of thyroid nodules. The immediate results after different thyroidectomy methods].

The extension of the resection for thyroid nodules depends both on nodules' nature and immediate or late postoperative complications risks. This clinical study analyzed the immediate complications appeared after partial thyroidectomy comparatively with those developed after total thyroidectomy. We studied 1411 patients operated in two clinics (from Romania and from France) which have two different attitudes concerning the width of the resection. Paralysis of recurrent laryngeal nerve occurred in 1.0% of patients with partial thyroidectomy and 3.0% of patients with total thyroidectomy, while only one patient (0.6%) developed permanent hypoparathyroidism after total thyroidectomy. In conclusion, total thyroidectomy can be performed by experimented surgeons with a recurrent or parathyroid injury risk similar to partial thyroidectomy. However, the surgeon should take into account the patient survey capacity and the discomfort produced by life substitutive treatment.

[When to prescribe scintigraphy in the exploration of thyroid nodules?].

Scintigraphy is employed almost systematically in current medical practice for initial thyroid nodules investigation. More and more authors observed that scintigraphy has lost importance confronted with others modern exam, but there are no statistical essay to demonstrate this fact. The aim of our work was to study, on 369 patients, the real contribution of scintigraphy to establish diagnosis and therapeutical strategy. Scintigraphy was truly useful only in 47 (12.7%) patients. We may conclude that thyroid scintigraphy ought to be indicated only in low TSH thyroid nodules, ectopic goiter and, eventually, in metastasis uptake radioactive iodine.

[De-epidermized free skin graft in the treatment of eventrations and hernias].

The study investigated the efficiency of the non-epidermic free skin graft in the treatment of eventration and of hernia. It includes an experimental and a clinical stage. The experimental study investigated the biological integration of the autograft and of histological changes that take place. The authors attempted to determine the optimal site for the insertion of the graft between the parietal anatomic layers, as well as to evaluate their role as a prosthesis. The experiments demonstrated a perfect integration of the dermal auto-graft, as well as the new solidity that it will impart to the wall. The non-epidermic free skin graft was used over a period of 15 years (1964--1978) in a total of 134 patients. The use of the dermic graft is simple from the technical viewpoint, and the post-operative morbidity is not significant. A retrospective clinical study was carried out in 62 patients over a period of 1 to 12 years. Only two relapses were noted (3,2 percent of the total). In the remaining cases the abdominal wall was very solid and there was no sign of eventration.

[Treatment of hernias and eventrations with alloplastic material (Mersilene type mesh)].

Between 1973 and 1979 the authors have performed 126 interventions, as follows: 27 hernias (18 of the inguinal type and 9 umbilical ones), and 99 eventration. They used alloplastic materials for consolidation or substitution of the musculo-aponevrotic wall of mediocre quality. In practice the "Mersilene" alloplastic material was used, made of dacron fibers, which provides a series of advantages: good tolerance, efficient sterilisation without undergoing degradation, possibility for use in reparation of large wall defects, high resistance. The net was applied for consolidation purposes in most of the cases (111 in all), and was placed either above the aponevrosis, or pre- or intra-peritoneally. In 15 patients it was used for substitution, when eventration resulted in a large muscular-aponevrotic defect. The results were very good, and a single recidive was noted, as well as two partial rejections, that did not however result in recidives.
