We present a case of a 37-year-old female, with large adenocarcinoma of transverse colon, and metastases in spleen, liver, peritoneum, greater omentum, gall bladder and right adnexa. She was transferred to our Hospital, and extensive elective cytoreductive surgery with intraabdominal hyperthermal chemotherapy (HIPEC) was performed. Couple of months later, she was operated on for a newly evidenced secondary nodus in liver segment VII, and metastasectomy was performed. Throughout entire postoperative period she was receiving cyclic chemotherapy. At this point, 2 years from the first operation, she was without evidenced recurrence of the disease. Aggressive cytoreductive surgery with multiorgan resection, peritonectomy, HIPEC and adjuvant chemotherapy which was proved to be a feasible option in some patients, with synchronous liver resection (LR) proved to be feasible and beneficial for patients with three or fewer liver metastases. This is the first liver resection included in usually performed cytoreductive surgery and HIPEC in Croatia.

Metastatic tumors of the long bones usually present with severe pain refractory to analgesic therapy. Pathologic fractures of the bone may lead to the significant decrease of patient's quality of life and necessitate further surgical therapy. We present 66 year old female with metastatic left breast carcinoma (T2N0M0) diagnosed 5 years before presentation of the metastatic lesion of the right femur causing severe pain in the middle of the right upper leg. Pain persisted after palliative irradiation therapy. We performed radiofrequency ablation of the metastatic lesion of the right femur using R.I.TA. Medical System Generator. This resulted in total necrosis of the tumor mass that caused osteolysis of the internal part of the femoral cortex. First three months after RFA procedure, the pain and tenderness were absent and normal daily activities were performed without restrictions.

Radiofrequency ablation (RFA) is one treatment modality for unresectable liver metastases. Patients with hepatic malignancies (n = 24) underwent elective RFA. All tumors were ablated with a curative intent, with a margin of 1 cm, in a single session of RFA. The median diameter of tumor was 3.1 cm (range 1.7-6.9 cm). Studied patients were not candidates for resection due to multifocal hepatic disease, extrahepatic disease, proximity to major vascular structures or presence of cirrhosis with functional hepatic reserve inadequate to tolerate major hepatic resection. Complete tumor necrosis was achieved in 87.5% and tumor recurred in 3 patients (12.5%) with lesions larger than 5 cm. Distant intrahepatic recurrence was diagnosed in another 4 (16.7%). Distant metastases were found in 7 (29.2%) patients. Four of these 7 patients had also distant intrahepatic recurrence of disease. Two and 5-years survival rates were 41.7% (10 patients) and 8.3% (2 patients) respectively. RFA is safe and effective option for patients with unresectable hepatic malignancies smaller than 5 cm without distant metastatic disease. RF ablation resulted in complete tumor necrosis in 87.5% with 2 and 5-years survival rates much higher than with chemotherapy alone or only supportive therapy, when survival is measured in weeks or months. If RFA is unavailable, percutaneous ethanol injection therapy can be done but with inferior survival rates.

Gastrointestinal duplications are an uncommon congenital abnormality that manifest before the age of two in 80% of cases. Ileal duplication is the most common while colonic duplication, either cystic or tubular, occurs in 10%-15% of cases and remains asymptomatic and undiagnosed in most cases. Mostly occurring in pediatric patients, colonic duplication is encountered in adults in only a few cases. The most common clinical manifestations are abdominal pain and intestinal obstruction. Rarely, duplications present with signs of acute abdomen or acute bleeding. This study reports a case of colonic duplication in an adult who presented with chronic constipation. Complete diagnostic workup was made on several occasions during the previous eight year period, but no pathology was found and chronic constipation was attributed to hypothyroidism caused by long standing Hashimoto thyroiditis. Multislice CT, performed because of abdominal distension, defined colonic pathology but the definite diagnosis of duplication of the transversal colon was made at operation. The cystic duplication and the adjacent part of the ascending and transversal colon were excised en-block. This study implies that colonic duplication, though uncommon, should be included in the differential diagnosis of chronic constipation even when precipitating factors for constipation, such as hypothyroidism are present.

We present a case of a 25-year-old female with diagnosed familial adenomatous polyposis and elevated carcinoembryonic antigen with negative family history. The suspicion of Gardner's syndrome was raised because extirpation of an osteoma of the left temporo-occipital region was made 10 years ago. Restorative procto-colectomy and ileal pouch anal anastomosis was made but histology delineated adenocarcinoma of the rectum (Dukes C stage). We conclude that cranial osteomas often precede gastrointestinal manifestations of familial adenomatous polyposis or Gardner's syndrome and such patients should be evaluated with genetic testing followed by colonoscopy if results are positive to prevent the development of colorectal carcinoma. If the diagnosis is positive all family members should be evaluated for familial adenomatous polyposis.

Hemorrhoids are a common condition in adult population with prevalence of about 4%. Only a third of patients with symptomatic hemorrhoids seek medical help. The annual rate of office visits for hemorrhoids is 12 for every 1000 patients in the United States. Hemorrhoids consist of connective tissue cushions surrounding direct arteriovenous communication. They can cause bleeding, pain and itching but other anorectal diseases should be ruled out. Current guidelines recommend a minimum of anoscopy and flexible sigmoidoscopy for bright-red rectal bleeding. Care depends on the extent of hemorroids. First-degree hemorrhoids can be managed with medical treatment. Surgery is reserved for patients with third and fourth-degree hemorrhoids and failure of nonoperative treatment. A new method of the stapled hemorrhoidectomy has been introduced which significantly reduces postoperative pain, hospital stay and use of analgesics with results that are equal to excisional hemorrhoidectomy.

This paper is concerned with large-gauge needle biopsies of suspicious breast neoplasia performed within a three-year period (22nd June 1999 through 21st December 2001). Within that time 262 large-gauge needle biopsies as well as cytological punctions were performed with the aim of diagnosing benign and malignant neoplasia. In the same three-year period 29 malignant breast tumors were diagnosed. In one of the patients a clinically and PHD verified alteration was found which pointed to Mb. Padget, while in another patient an atypical ductal hyperplasia was confirmed by a pathohistological test.

The results of surgical treatment of ulcerative colitis in 19 patients in the period from 1989 to 1997 are presented. Of surgical techniques, in 17 patients a pouch was formed, namely, in six patients W pouch, in four patients S pouch, and in seven patients J pouch, while in two patients the pouch was not formed due to the incontinence of anal sphincter. In these patients the stool derivation was achieved by permanent terminal ileostomy. Fifteen patients were operated in elective program, while in four patients emergency surgery was indicated. In emergency surgery the first step was subtotal colectomy, with ileostomy and sigmoidostomy. In further treatment we introduced corticosteroid clyster in the opening of sigmoidostoma, with good results. The quality of life of persons with the pouch is higher compared to patients with permanent ileostomy. In patients who require surgical treatment of ulcerative colitis, the operation of forming an ileal pouch and anal anastomosis should be done.

The case of a patient with sudden onset of abdominal pain, hepatomegaly and laboratory findings which indicated necrosis of a parenchymal organ is reported. Patient died soon after the admission to hospital after fulminant disease development. At the time of admission diagnosis of hepatic vein occlusion, i.e., Budd-Chiari syndrome was made based on ultrasonographic finding. Obduction confirmed this finding showing lung adenocarcinoma with liver metastases as well as occlusion of all hepatic vein branches with thrombi. This report emphasizes the role of ultrasonographic diagnostics in the early diagnosis of Budd-Chiari syndrome.

In the present study, the flow in deep, closed wound with various types and position of drain was studied. A physical model of regular geometrical wound was designed to investigate the events occurring in the wound from the standpoint of hydraulics. Results of the study showed that the commonly used method of drain application could be improved. The results may also prove helpful for improvement of the existing drains and their more favorable positioning.

The aim of the study was to reveal the histopathologic features of intestinal inflammation as demonstrated in BALB/c mice, using the challenge of 2,4-dinitrofluorobenzene (DNFB) with or without previous sensitization. Forty mice were randomized into 5 groups. Two groups of animals were treated with rectal enema of 0.2% or 1.0% of 2,4-dinitrofluorobenzene solution. Third group was pretreated with 2 sensitizing doses of DNFB. Two control groups were treated with PBS or acetone and vehicle enema only (acetone and olive oil). In order to assess the extent of colonic inflammation and damage, a histopathologic score scale was developed. In contrast to scanty superficial ulcerations and mild edema observed in the control group of animals, edema, ulcerations, hemorrhage, necrosis and infiltration of inflammatory cells were observed in experiment groups treated with enema of DNFB. Total score of lesion as well almost all inflammatory parameters of injury observed were highest in previously sensitized animals. The results of this study clearly demonstrated the pattern of colonic inflammation induced with DNFB using the histopathologic scoring scale system.

The aim of this study was to evaluate the flow of fluid between closed drains in deep wounds and osteomyelitic and abscess cavities. For the purposes of this study we created a numerical wound model. This model had a symmetric geometrical shape and we simulated flow of fluid between the drains in four variants of distance between these drains. The results of this model showed that the distance often used between drains in clinical practice is not effective. Better drainage could be achieved by spacing the drains more. These results can be used for more functional and better drainage if drains are placed properly in osteomyelitic or wound cavities.

Although free jejunum transfer has become an accepted form of hypopharyngeal reconstruction, an ideal method of monitoring the viability of the graft has not been devised yet. The method of direct visualisation through the incision in the skin above the transferred jejunum has proven very reliable and easy to perform, especially for the nursing staff. This reliable method of monitoring free vascularised jejunum to the neck region has been used in two patients. After two days of direct monitoring, the incision in the skin healed without additional sutures. No failures of the graft occurred, and 12 days later the patients were able to swallow fluids without difficulty. The effectiveness of this technique has surpassed that of all previously published methods.
