I. Juvara (1913-1996), a surgeon for all seasons.

Ion Juvara is a creator of a genuine Romanian school of surgery. If I. Juvara had lived and worked in a country that had been the proud owner of a Pantheon, undoubtedly he would have rested there to the end of time, among the eternal ones i.e. those who triumphed against time and who had never been defeated. If the first generation of Romanian surgeons represented mainly by Thoma Ionesco (1860-1926) was educated mainly abroad, the next generation was trained professionally at the Romanian school of surgery. Despite of the hostile period he lived in, I. Juvara kept intact his freedom of thinking and opposed with all his powers abuses of any kind, always preserving his integrity, avoiding with elegance the traps of the totalitarian regime. But even so nobody can state that the professor, who came from -Moldavia, as his master, N. Hortolomei, could not say at the end of his life that he hadn't had a fulfilled professional life, as he is considered even today the greatest surgeon of Romania in the latter half of the 20th century. He was, after all, a surgeon for all seasons.

Rare Tumors, Rare Association: Ovarian Strumal Carcinoid - Retroperitoneal Cystic Lymphangioma.

INTRODUCTION: Strumal carcinoid is a rare neoplasm of the ovary containing thyroid (struma) and carcinoid component revealed by immunohistochemistry. Case present: A 55-years-old woman with hysterectomy and right oophorectomy for uterine leiomyoma and right ovarian cyst, performed 12 years ago, was referred to the First Surgical Clinic, St. Spiridon University Hospital Iasi with pain in hypogastrium present for 2 months. Laboratory tests are normal and serum testing for tumor markers is unchanged. Ultrasound and CT finds for topography of the left ovary a well-defined 63 57 71 mm cystic mass, with a non-uniform wall thickness. Exploration laparoscopy, after adhesiolysis, identifies a cystic tumor developed in mesosigmoid which was excised and auterine tube with cystic dilatation and left ovary with intactcapsule, for which we performed left adnexectomy and extracted pieces of tumors in endobag. Evolution is simple, the patient being discharged after 3 days postoperatively. Histopathological exam and immunohistochemistry reveal edovarian strumal carcinoid and cystic lymphangioma. After one year follow up the patient is disease free. CONCLUSION: This association between an ovarian strumal carcinoid with mesosigmoidian cystic lymphangioma is unusual and rare, not cited in the literature. A laparoscopic approach for the two conditions is safe with good immediate and distant postoperative course.

Appendicular Mucocele: Possibilities and Limits of Laparoscopy. Brief Series and Review of the Literature.

INTRODUCTION: Appendicular mucocele, a cystic dilatation of the appendix, is a rare disease, but unfortunately about 1/10 of cases evolves into pseudomyxoma peritonei. METHODS: We performed a prospective study between 1 January 2010 to 31 December 2014 in order to track the incidence, symptoms, and circumstances of diagnosis, treatment and evolution of these rare tumors. RESULTS: A total of seven patients underwent curative surgery for a mucocele of the appendix: one woman and six men with an average age of 59.71 years. Clinical signs, present in two cases, were uncharacteristic. Ultrasound performed in all cases, could guide diagnosis in 5 cases. CT performed in 5 cases diagnosed only two cases. All cases were operated on: the open approach was used in four cases and a minimally invasive in three cases. We performed two right colectomies, an open appendectomy associated to anterior resection of the rectum, two laparoscopic appendectomies and two appendectomies and cecum resection with stapler, one by open approach and one by a minimally invasive approach. Intraoperative spillage of mucinous tumor did not occur in any case. The mean hospital stay was 5.7 days. Postoperative complications were present in 1 case (14.2%): wound infection. The average follow-up period was 40.28 months. (Range 6 to 48 months). No tumor recurrence or readmission, such as pseudomyxoma peritonei, has occurred. CONCLUSIONS: Appendicular mucocele is a rare entity; it can be found incidentally and it can mimic acute appendicitis, appendicular plastron or cecum tumor. Once diagnosed, surgical treatment is required for fear of perforation, tumor evolution and the emergence of the rule of complications. Laparoscopic approach in selected cases can be used, accompanied by safety measures to avoid iatrogenic perforation and peritoneal and parietal seeding.

Parastomal hernias -- clinical study of therapeutic strategies.

UNLABELLED: Parastomal hernias are parietal defects adjacent to the stomasite, after ileostomy and colostomy. Their incidence is variable and they are generally underestimated. METHODS: Between 2001 and 2010 at the First Surgical Clinic Iasi, we treated 861 incisional hernias, of which there were 31 parastomal hernias in 26 patients (3%), 5 of which were recurrent parastomal hernias. Parastomal hernias have been explored clinically, through imaging and intraoperatively.Because our experience and literature review have demonstrated that a mesh repair is a safe procedure in the treatment of parastomal hernia, in 2010 we initiated a prospective randomized trial on the use of prophylactic polypropylene mesh at the time of stoma formation to reduce the risk of parastomal hernia. We enrolled in the study 20 patients with mesh implanted at the primary operation and 22 patients without mesh. The inclusion criteria were: patients with low rectal cancer, stage II-III, irradiated, obese, with a history of hernias, patients who do physical work. RESULTS: Most parastomal hernias were asymptomatic; only six cases with parastomal hernias required emergency surgical treatment. We performed local tissue repair in 16 cases (4 cases with recurrent parastomal hernia, stoma relocation in one case), sublay mesh repair in 15 cases (one case with recurrent parastomal hernia; stoma relocation in 5 cases). Postoperative morbidity registered included 4 wound infections (one case after mesh repair which required surgical reintervention) and stoma necrosis in one case with strangulation parastomal hernia with severe postoperative evolution and death. After local tissue repair recurrences were seen in 6 cases, after mesh repair we registered recurrence only in one case and no relapse after the relocation of the stoma. The patients with prophylactic mesh at the time of stoma formation to reduce the risk of parastomal hernia were followed for a median of 20 months(range 12 to 28 months) by clinical examination and ultrasound exam every 3 months. We registered 6 recurrences(27,2%), all in the no mesh cohort. We have not seen any morbidity in patients from the mesh group. CONCLUSIONS: Parastomal hernia is a relatively rare disease compared to the number of incisional hernias. With increasing life expectancy stands we noted increased incidence of parastomal hernia as well. Prophylactic use of mesh during the primary operation is a safe procedure and reduces the risk of parastomal hernia.

Gallstone ileus: a rare cause of intestinal obstruction -- case report and literature review.

Gallstone ileus is an uncommon complication of cholelithiasis with a high morbidity and mortality rate. We report a rare case of small bowel gallstone obstruction in an 87-year-old female patient with cholecystoduodenal fistula. We performed an enterolithotomy, repair of fistula and cholecystectomy. During the postoperative course a wound dehiscence appeared, which required suturing and prolonged hospitalisation. We review the diagnostic and therapeutic aspects, given that the diagnosis of this condition is usually difficult and often made intraoperatively.In fact, here is no standard surgical procedure for this disease. The one-stage procedure should be reserved for stabilized patients, but in cases with associated comorbidities,only enterolithotomy can represent the best option..

[The porcelain gallbladder-laparoscopic approach]. / Vezicula de portelan--abord laparoscopic.

A long time porcelain gallbladder was considered a relative contraindication to laparoscopic cholecystectomy, because of a high incidence of gallbladder cancer. From 12,000 patients underwent cholecystectomy in First Surgical Clinic of Iasi, 5 (0.04%) patients had porcelain gallbladder. All patients underwent ultrasound examen. Patients with porcelain gallbladder were classified as Type I to II according to preoperative ultrasound findings: three cases with porcelain gallbladder type I and two cases with porcelain gallbladder type II (in one case we found associated gallbladder carcinoma). We describe a three cases with porcelain gallbladder type I (complete calcification of gallbladder wall) treated by laparoscopic approach. Laparoscopic cholecystectomy was difficult because of adhesions and problems with grasping the thick gallbladder wall, but the postoperative course was uneventful. The histopathologic result of the specimen established the diagnosis of porcelain gallbladder type I and no cancer in the calcified wall of the gallbladder. We conclude based on cases presented and the literature review, although there is a high conversion rate, that patients with a type I porcelain gallbladder should be considered for laparoscopic cholecystectomy using a preoperative selection based on the ultrasound findings.

Laparoscopic approach to ovarian dermoid cysts.

INTRODUCTION: Ovarian dermoid cysts (mature cystic teratomas) are a benign type of germ cell tumours and the most common ovarian neoplasms in women of fertile age. The aim of this study was to analyze the safety of the laparoscopic approach in ovarian dermoid cysts. METHODS: We performed a prospective study between 2006 and ' 2010 including 38 mature cystic teratomas treated either laparoscopically or by open access. All preoperative and postoperative data were included in an MS Access database and statistically analysed with SPSS v. 17 for Windows. RESULTS: The study group was divided into 2 subgroups according to the approach: laparoscopic (25 cases - 2 conversions) and classic (13 cases). The mean age of the patients was 40.34 years (range 19-74): 36.92 years for laparoscopic group and significantly higher 46.21 years for open approach group. Twelve cases were admitted as emergencies either because of complications (torsion or rupture of the teratoma) (11 cases) or associated with acute appendicitis (one case). The latter did not influence the decision for open or laparoscopic approach. Only 29 out of 38 cases had preoperative measurement of CA 125. CA 19-9 was performed in 27 cases and elevated levels were found in 21 cases (78%). Cysts over 10 cm presented higher values of CA 19-9. The mean cysts diameter was 11.29 cm (range 2-27 cm): 13.93 cm mean cyst diameter for open approach vs 9.75 cm for laparoscopic approach. The specimen removal required aspiration of the content for cysts bigger the 10 cm in laparoscopic approach. Mean hospital stay was 4.05 days (range 2-6 days) for the laparoscopic group, significantly lower when compared with the open approach group: 6.96 days (range 5-16 days). CONCLUSIONS: Laparoscopic management of ovarian dermoid tumours is a safe and efficient procedure. It does not increase complications rate in comparison with the open approach, offering a shorter hospital stay, a quick recovery and very important, it allows a conservative treatment, especially in premenopausal women who want to be pregnant.

Antarctic aldehyde dehydrogenase from Flavobacterium PL002 as a potent catalyst for acetaldehyde determination in wine.

Latest solutions in biotechnologies and biosensing targeted cold-active extremozymes. Analysis of acetaldehyde as a relevant quality indicator of wine is one example of application that could benefit from using low-temperatures operating catalysts. In search of novel aldehyde dehydrogenases (ALDH) with high stability and activity at low temperatures, the recombinant S2-ALDH from the Antarctic Flavobacterium PL002 was obtained by cloning and expression in Escherichia coli BL21(DE3). Structural and phylogenetic analyses revealed strong protein similarities (95%) with psychrophilic homologs, conserved active residues and structural elements conferring enzyme flexibility. Arrhenius plot revealed a conformational shift at 30 °C, favoring catalysis (low activation energy) at lower temperatures. In addition to a broad substrate specificity with preference for acetaldehyde (Km = 1.88 mM), this enzyme showed a high tolerance for ethanol (15%) and several salts and chelators (an advantage for wine analysis), while being sensitive to mercury (I50 = 1.21 µM). The neutral optimal pH (7.5) and the stability up to 40 °C and after lyophilization represent major assets for developing S2-ALDH-based sensors. An enzymatic electrochemical assay was developed for acetaldehyde detection in wines with proven accuracy in comparison with the reference spectrophotometric method, thus evidencing the potential of S2-ALDH as effective biocatalyst for industry and biosensing.

Laparoscopic retrieval of gossypibomas--short series and review of literature.

UNLABELLED: Laparoscopic removal of retained abdominal foreign bodies represents an obscure domain of minimally invasive surgery. Although not an infrequent situation in general surgical practice, there are very few papers presenting laparoscopic approache in these circumstances. An iatrogenic foreign body following surgery, is a serious complication that may lead to medico-legal problem. We present our experience and a literature review. METHODS: In the last 20 years 48 patients with abdominal foreign bodies were referred to us. Out of these four gossypibomas were managed laparoscopically. RESULTS: Retained swabs represent the most common iatrogenic abdominal foreign bodies. Removal of gossypiboma present more problems in laparoscopic environment due to encapsulation and difficulties in localisation, as retained swabs unusually display radio-opaque markings. There was one conversion due to dense adhesion to the gastric wall. Postoperative recovery was uneventful in all cases. CONCLUSIONS: Gossypibomas, among abdominal foreign bodies, represent a certain reality with significant legal implications. Prevention should prevail and all efforts should be made in such respect. Laparoscopic approach is possible in selected cases (small swabs, encapsulated, no complications).

Laparoscopic surgical education--the experience of the first surgical unit Iasi.

The classic apprenticeship model for surgical training takes place into the operating theater under the strict coordination of a senior surgeon. During the time and especially after the introduction of minimally invasive techniques as gold standard treatment for many diseases, other methods were developed to successful fulfill the well known three stages of training: skill-based behavior, rule-based behavior and knowledge-based behavior. The skills needed for minimally invasive surgery aren't easily obtained using classical apprenticeship model due to ethical, medico-legal and economic considerations. In this way several types of simulators have been developed. Nowadays simulators are worldwide accepted for laparoscopic surgical training and provide formative feedback which allows an improvement of the performances of the young surgeons. The simulators currently used allow assimilating only skill based behavior and rule-based behavior. However, the training using animal models as well as new virtual reality simulators and augmented reality offer the possibility to achieve knowledge-based behavior. However it isn't a worldwide accepted laparoscopic training curriculum. We present our experience with different types of simulators and teaching methods used along the time in our surgical unit. We also performed a review of the literature data.

[Small bowel tumours from barium meal to capsule endoscopy and from open to laparoscopic approach]. / Tumorile intestinului subtire de la tranzitul baritat la enteroscopie, de la abordul clasic la cel laparoscopic.

INTRODUCTION: Tumors of the small bowel are rare and present with nonspecific symptoms. That causes a significant delay in diagnosis and consequently a worse outcome for the patient. METHODS: In a retro-prospective study we evaluated a series of 63 patients with small bowel tumors operated in the First Surgical Clinic Iasi, during 1992-2010: 18 duodenal tumors, 26 jejunum tumors and 19 ileum tumors. There were 18 (28.6%) cases with benign tumors and 45 (71.4%) cases with malignant tumors (41 primary tumors and 4 secondary tumors). We discuss problems related to diagnosis, treatment and prognosis of these tumors in the presence of new explorations (capsule endoscopy, enteroscopy) and minimally invasive approach. RESULTS: Duodenal tumors were malignant in 14 cases (11 adenocarcinomas, 3 malignant GIST tumors) and benign in 4 cases (adenoma, lipoma, GIST tumor, schwannoma) which led to stenosis in 5 cases, upper gastrointestinal bleeding in 3 cases. Positive diagnostic was confirmed with barium meal and endoscopy. The jejunal and ileal tumors were mostly malignant 31 cases (13 carcinomas, 10 lymphomas, 2 malignant GIST and one sarcoma) with only 14 cases of benign tumors (5 GIST). Their tendency was to present as emergencies: 17 obstructions and 5 peritonitis. Modem imagistic proved useful as diagnostic tool: capsule endoscopy, CT-scan and enteroscopy. The benign tumors benefited from local resection (5 cases) and segmental enterectomy (12 cases), while malignant tumors were managed using Whiple's procedures (10 cases), duodenal-jejunal resections (1 case), segmental enterectomy (29 cases), ileocolectomy (2 cases) and three bypasses. Laparoscopic approach was performed in 8 cases. CONCLUSIONS: The incidence of small bowel tumors remains low. For diagnosis, CT-scan, enteroscopy and capsule endoscopy are very useful; unfortunately the last method is not practicable in emergency. Surgery is the best choice plus chemotherapy for some malignant tumors. Laparoscopic approach is feasible in selected cases.

Laparoscopic management of gastrointestinal stromal tumours.

UNLABELLED: Gastrointestinal stromal tumours (GISTs) represent the most common non-epithelial tumour of the digestive tract. Laparoscopic approach may be considered ideal for the resection of these tumours. Their particular biological behaviour allows for a curative resection even without large resection margins and extensive lymphadenectomies. METHOD: Over a period of five years, eight patients benefited from laparoscopic resections (six patients with primary gastric GIST and two patients with small bowel GIST). Pathological features were analyzed including tumour size, surgical margin status, immunohistochemical staining profile, and tumour mitotic index. All cases were confirmed GISTs by immunohistochemical staining. RESULTS: The mean age of the patients was 61.6 years (range 48-71 years). Of these patients, five initially presented to hospital with acute gastrointestinal haemorrhage (four cases) or occult bleeding (one case). Gastric or small bowel tumours were identified during subsequent investigation. A presumptive diagnosis of gastric GIST was made in gastric lesions based on endoscopic, ultrasonic, and CT scan characteristics. Small bowel tumours were identified and presumed to be GIST based on information gathered from video capsule endoscopy, enteroscopy and CT scan. Complete resection was obtained with laparoscopic approach in six cases, while in two cases resection was laparoscopically assisted, with added oncology safety margins as preoperative definitive diagnosis was not available. Tumours varied in dimension from 2.5 cm to 9 cm and their malignant risk score using Fletcher criteria was low in three cases, intermediate in three cases and high in two cases. Mean postoperative stay was 3.8 days and there were no complications, nor postoperative mortality. After a mean follow-up of 26 months (range 1 to 60 months) all patients are symptom free and free of recurrent disease. CONCLUSIONS: A selective approach to laparoscopic resection of gastro-intestinal GISTs allows safe resection and very good results, on the condition that a clear diagnosis of GIST has been established on preoperative assessment. The laparoscopic feasible and safe considering the biological particularities of GIST, and it carries no additional risks.

Peritoneal tuberculosis in laparoscopic era.

UNLABELLED: Peritoneal tuberculosis is uncommon in developed countries, but as the general incidence of tuberculosis is on the rise in Romania so is the case with peritoneal localization of the disease. The present study retrospectively analyzed 18 patients (8 males and 10 females, mean age 50 years, range 17-74 years) diagnosed in our department with peritoneal tuberculosis between 1995 and 2007. RESULTS: Ascites was present in all but one case. Other common findings were weight loss (12 cases), weakness (5 cases), abdominal pain (16 cases), anorexia (6 cases) and night sweat (3 cases). Abdominal ultrasound has been used to demonstrate ascites in 16 cases. Only two patients had chest radiography suggestive for active tuberculosis. Laparotomy was performed in four cases, laparoscopy in 14 cases (two conversions). Intraoperative findings included multiple diffuse involvements of the visceral and parietal peritoneum, white "miliary nodules" or plaques, enlarged lymph nodes, ascites, "violin string" fibrinous strands, and omental thickening. Biopsy specimens showed granulomas, while ascitic fluid showed numerous lymphocytes. We conclude that the symptoms of abdominal tuberculosis vary greatly, and laparoscopy can be essential for diagnosis and management. The operation is safe, reliable with few complications and permits a prompt diagnosis, necessary to cure the patient.

Small Bowell Malignant Melanoma-Report of Three Cases and Review of Literature.

Malignant melanomas have a predilection to metastasize to the small bowel. Three patients with malignant melanoma involving the small bowel are reported. Two patients were operated on for small bowel obstruction and the third for gastrointestinal bleeding with anemia. Two patients remained well 6 month and 2 years, respectively, after surgery. One patient died of metastatic cerebral melanoma 6 months postoperatively. One should suspect small bowel metastasis in every patient with malignant melanoma in his past medical history, who presents with recent changes in bowel habits, intestinal obstruction or gastrointestinal bleeding. Preoperative assessment can only raise the suspicion, even with advanced imaging methods: capsule endoscopy, enteroscopy, CT or PET-CT. The only therapeutic procedure is surgical resection, offering both short term survival as well as an improvement in the quality of life. Although prognosis is dismal there are factors associated with prolonged survival: complete surgical resection with no residual primary or metastatic tumor, so-called primary small bowel tumors in patients aged more then 60 years, LDH < 200 U/L, lack of tumor spread in mesenteric lymph nodes.

[Surgical treatment of hyperparathyroidism]. / Tratamentul chirurgical al hiperparatiroidismului.

BACKGROUND: Hyperparathyroidism (HPT), the result of excessive secretion of the parathormone, is one of the most common endocrine disorders. In most forms of HPT, surgical parathyroidectomy is the best choice. AIM: This paper aims to examine patients with hyperparathyroidism operated in First Surgical Unit Iasi, in terms of indications, surgical technique and postoperative results. MATERIAL AND METHOD: We performed a retrospective study, in First Surgical Unit Iasi, during 2000-2008. Clinical, laboratory, intraoperative and histopathological data were included in a MS Access Office XP database. Statistical analysis was performed with the SPSS ver. 15.0 for Windows (Statistical Package for the Social Sciences, Chicago, Ilinois). RESULTS: There were examined 34 patients with HPT: 32 cases were primary HPT (94.12%), and two cases with secondary HPT (patients with renal failure). The men/women ratio was 6/28 and mean age was 50.09 +/- 2.23 years old. Clinical presentation was variable: the dominant symptoms were osteoarticular (67.6%) followed by neuropsychological (64.7%), digestive (17.6%) and renal (11.8%). Associated diseases were recorded at 47.06% of patients: arterial hypertension--32.4%, coronary heart disease--23.5%, heart rhythm disorders--17.6%, diabetes--11.8%, biliary lithiasis--5.9%, renal lithiasis--8.8% and thyroid hypertrophy--55.9%. In 8 cases, primary hyperparathyroidism was associated with other diseases of the endocrine glands: 4 cases with Multiple Endocrine Neoplasia (MEN) type 1; a patient with von Recklinghausen disease; a patient with associated hypothyroidism and diabetes; two cases that with papillary thyroid carcinoma. Positive diagnosis was supported by determining serum calcium, phosphorus and serum concentration of the parathormone (PTH). All patients were evaluated by ultrasound exam; the sensitivity of the investigation was 88.23%. 99Tc-sestamibi scintigraphy was performed in 32.35% of patients with a sensitivity of 72.72%. Parathyroidectomy was performed by Kocher's incision in 88.23% and minimally-invasive open approach in 11.76%. The following types of interventions have been performed: tumor resections (73.53%), subtotal parathyroidectomies (17.6%), total parathyroidectomies (8.82%). In patients with associated thyroid disease total thyroidectomies (26.5%) and subtotal thyroidectomies were done (11.8%). The postoperative morbidity rate was 2.9% (transient hypocalcemia). Histopathological examination revealed the presence of parathyroidian adenoma in 67.6% of patients (N=23), parathyroidian hyperplasia in 26.5% (N=9) and parathyroidian carcinoma in the others 5.9% (N=2). CONCLUSIONS: The diagnosis of HPT involves positive determination of calcium and PTH. The most useful imaging techniques, are 99Tc-sestamibi scintigraphy and ultrasonography, which locates in most cases, the parathyroid pathological glands. Surgical treatment is the only curative treatment of HPT, with medical treatment only role in preoperative preparation. The precise site of the parathyroidian lesion facilitates minimally-invasive approach. The postoperative follow-up is mandatory because of the increased potential for recurrence and for diagnosis of other endocrine tumors (in patients with MEN).

The anatomy of a horizontally impacted maxillary wisdom tooth.

A completely horizontally impacted upper third molar was revealed after routine dissection of a 62-year-old human cadaver of a Caucasian male. The molar was penetrating into the maxillary sinus and there was antral dehiscence of its bony alveolus. The bony alveolus was immediately in front of the greater palatine canal contents, and the bottom of the alveolus was dehiscent towards the greater palatine foramen. Within the greater palatine canal and foramen the greater palatine artery was duplicated and the nerve was found. Such antral relations of an impacted upper third molar predispose to oroantral communications if extraction is performed, while the close neurovascular relations represent a risk factor for postextractional haemorrhage and neurosensory disturbances and must be borne in mind when deciding on or performing the extraction.

[Pyogenic liver abscesses]. / Abcesele hepatice piogene.

BACKGROUND: Pyogenic liver abscesses were a relative rare disease. In the last decades the management of the liver abscesses was changed due to the new imaging and surgical techniques. AIM: To evaluate the clinical features, imaging techniques and treatment of the liver abscesses. METHODS: We performed a retrospective study during the last twenty years (1987-2007). The patients were divided in two groups: group I treated during the period 1997-2007 and group II, 1987-1996. We compare the clinical features, biological tests, imaging techniques and the treatment. RESULTS: Of the 71 patients with liver abscesses, 39 (54.9%) were included in group I and 32 (45.1%) in group II. The male/female ratio was 49/22; liver abscesses were more frequent to the males, in group I (63.3%) and more frequent to the women, in group II (63.6%) (p = 0.035). The mean age was 47.49 +/- 2.09 years old (range 18-85) with no difference between the groups (p = 0.059). The symptoms were similar in the two groups. We noted, as associated disease: diabetes--16% (N = 12), liver cirrhosis--7% (N = 5), malignancies--4.2% (N = 3). White blood cells were higher than 10000/mm3 in 51 patients (71.83%); a severe anemia with hemoglobin levels less than 10 g/dL was found in 25 cases (35.21%). All cases were investigated by ultrasound exam, but CT scan was performed in only 25 cases (19.71%). The abscesses were situated into the right lobe in 53 cases (74.6%), into the left lobe in 13 cases (18.3%) and into the both lobes in 5 patients (7%). The etiology was diverse: 25.4% after hepatic hydatid cysts, 12.7% with biliary origin, 22.5% with hematogenous and phlebitis origin and 39.4% with unknown origin (cryptogenetic). Treatment of the liver abscesses was surgical, by open (87.3%) or laparoscopic approach (8.5%), and percutaneous (ultrasound guided punction)--2.8%. One case was medical treated (antibiotherapy). Bacteriological exam found aerobic germs in 45 patients (64.28%), anaerobic germs in 3 patients (4.28%); the pus was sterile in 22 patients (31.43%). The intraoperative mean dimension of the liver abscesses was 74.26 +/- 4.35 mm (range 30-160), similar with dimensions measured by echography 72.29 +/- 4.84 mm (range 12-179)--p < 10(-3). Intraoperative bleeding was noted in 29 patients (40.8%). Univariate analysis revealed as prognosis factors for intraoperative bleeding, diameter of the liver abscess (p < 10(-3)), dimension of the residual cavity (p < 10(-3)) and the pus volume (p < 10(-3)). The multivariate analysis, by logistic regression, revealed as prognosis factors for intraoperative bleeding, pus volume (p = 0.006) and hemoglobin level (p = 0.035). Postoperative morbidity was 43.7%. Univariate analysis and logistic regression revealed the pleural effusion as prognosis factors for postoperative complications (p = 0.046) and, respectively, intraoperative hemorrhage (p = 0.010) and splenomegaly (p = 0.007). Postoperative mortality rate was 2.81%. CONCLUSIONS: Pyogenic liver abscess is a challenging disease with high rate of postoperative morbidity. Most of the abscesses are unique and situated in the right lobe of the liver. The imaging techniques, especially ultrasound exam and CT-scan, are essential for the diagnosis and the treatment of liver abscesses. The treatment is usually surgical, by open or laparoscopic approach; in selected patients the percutaneous approach can be performed.

[Surgical treatment of gynecomastia]. / Tratamentul chirurgical al ginecomastiei.

BACKGROUND: Gynecomastia describes a benign increase of the mammary gland in men. When medical treatment fails, the surgical procedure is the treatment of choice. There are two main surgical procedures: subdermal mastectomy and liposuction. AIM: To evaluate the results after surgical treatment (mastectomy) performed in a general surgery unit. METHOD: We performed a retrospective study; all the patients operated for gynecomastia were reviewed. The clinical, imaging, biological, intraoperative and histological data were included into a MS Access database and statistical analyzed. RESULTS: From 1990-2007, 114 patients were admitted in the First Surgical Clinic Iasi for gynecomastia. Only 12.6% from the patients were with bilateral gynecomastia. The mean age was 40.54 +/- 1.83 years old (range 12-84). Mean body mass was 26.72 +/- 0.46 kg/m2 (range 18.5-41), and about 20% from the patients had a BMI of over 30 kg/m2. We also noted that 46.5% were smokers. Simon classification was used for preoperative staging: 2.6% from the cases (N = 3) were included in stage I, 16.7% (N = 19) in stage IIa, 50% (N = 57) in stage IIb and 30.7% in stage III. The patients included in stages IIa and I are younger then the patients included in stage III (p = 0.024). Mastodynia was noted in 46 cases (40.4%). Ultrasound exam was performed in all the cases, and the larger diameter of the nodule measured was 3.75 +/- 0.18 cm (range 0.5-9.7). Only three cases were preoperatively treated with tamoxifen. Most of the cases were operated using general anesthesia (53.5%). Mastectomy was performed by peri-areolar (70.2%), elliptical (28.9%) or radial (0.9%) incisions. The subdermal mastectomy using peri-areolar approach was performed especially for the cases included in stages I, IIa and IIb--p < 10(-3). The epi-pectoral vacuum drainage has been used in 79.8%. The postoperative morbidity rate was 15.8%--4 cases of hematoma, 13 cases of seroma and 1 case complicated with skin necrosis. No specific risk factors for postoperative complications were found by univariate and multivariate statistical analysis. The pathological exam revealed pseudo-gynecomastia in 6 cases; the other cases presented dilated ducts. We also noted intraductal papillary hyperplasia in 87 cases and chronic inflammation in 35 cases. The histological exam also revealed intraductal papilloma--9 cases, fibro-adenoma--1 case, papillary ductal carcinoma--1 case and mucinous carcinoma--1 case. From all these data, the etiological diagnosis in presented series was: pseudo-gynecomastia--5.3% (N = 6), idiopathic--64.9% (N = 73), endocrine--7.9% (N = 9), drug induce--5.3% (N = 6), metabolic--7.9% (N = 9), tumoral--8.8% (N = 10). The postoperative hospital stay was 4.04 +/- 0.26 days (range 1-12). A literature review has also been performed. CONCLUSIONS: The management of gynecomastia has to be performed by a multidisciplinary team. Gynecomastia it is possible to be associated with a breast cancer, even in younger people. The surgical treatment, especially the type of incision, will be chosen from point of view of Simon stages. Liposuction can be associated in selected cases.
