[LAPAROSCOPIC PARTIAL PERICYSTECTOMY OF SPLENIC HYDATID CYST - A CASE REPORT]. / LAPAROSKOPSKA PARCIJALNA PERICISTEKTOMIJA EHINOKOKNE CISTE SLEZENE - PRIKAZ BOLESNICE.

Echinococcal cyst of the spleen is usually a result of infection with the parasite Echinococcus granulosus. The spleen is the third most frequent localization of echinococcus after liver and lungs. Partial laparoscopic pericystectomy can be done without the loss of blood and scattering of scolexes with spleen preservation and conservation of its immune function. We present the patient with a large (1 8 x 16 x 12 cm) echinococcal cyst of the spleen that compressed the surrounding organs (stomach, transverse colon, pancreas and left kidney), and prevented normal passage causing vomiting after every meal. In this patient, PAIR procedure (puncture, aspiration, injection, reaspiration) and conservative treatment was attempted on several occasions without success. Finally, laparoscopic partial pericystectomy was performed, evacuating the contents of the cyst. The surgery lasted 120 minutes. Postoperatively the patient was without complications. Hospitalization lasted five days. Six months later, the patient is without problems. These echinococcus cysts of the spleen cannot be solved using PAIR technique and conservative treatment. Laparoscopic partial pericystectomy is a better solution than open surgery due to less trauma to the patient, especially in elderly people.

Emergency surgery for large bowel obstruction caused by cancer.

There are several options for surgical treatment of large bowel obstruction caused by cancer, depending on location of obstruction, intraoperative local findings (perforation, peritonitis, bowel dilatation proximal to obstruction) and patients' condition. Resection and anastomosis as one stage surgery would be prefered procedure. Anastomotic leakage, on the other hand, highly elevates risk of mortality and mobidity. The most important question is whether to, in resectable cases, perform primary resection with anastomosis or not. This study was retrospective and included 40 patients that have undergone emergency surgery for large bowel obstruction caused by cancer. According to whether resection and anastomosis was made at initial surgery or not, patients were grouped in group A (N = 18) and group B (N = 21), respectively. We have analysed the type of surgical procedure, days of hospitalization, mortality, anastomotic leakeage, wound infection and other postoperative complications. Our results show that there is no major difference in mortality and morbidity in these two groups, suggesting that for selected patients primary resection and anastomosis is a safe option of tratment with acceptable risk. Since there are no strict guidelines or scorring system which would point the tratment option the decision about the choice of procedure still remains the burden of surgeon and depends on its experience and subspeciality. Our experience recomends primary resection and anastomosis except in cases of bowel perforation on tumor site, in cases of extreme dilatation and atony of bowel proximal to obstruction site and severe hypoproteinemia and anemia.

Laparoscopic surgery for large hydatide liver cyst after two previous laparotomies.

Laparoscopic surgery for hepatic echinococcosis is a technically difficult and demanding surgical procedure even for the most experienced abdominal surgeon. Surgery is performed after the conservative treatment with albendazole for 28 days. We report a case of laparoscopic partial pericystectomy with biliostasis and omentoplasty in a patient with two previously open surgeries (laparotomies)--right subcostal laparotomy for acute inflammation of the gallbladder and right pararectal laparotomy for perforated gangrenous appendix. The patient underwent extensive laparoscopic adhesiolysis due to pronounced intra-abdominal adhesions to gain access to a large hydatid cyst with the diameter of 11 cm. Laparoscopic surgery is much less traumatic to the patient with a better cosmetic effect.

Prognostic Value of Apparent Diffusion Coefficient (ADC) in Patients with Diffuse Gliomas.

This study aimed to evaluate potential posttreatment changes in ADC values within the tissue surrounding the enhancing lesion, particularly in areas not exhibiting MRI characteristics of involvement. Additionally, the objective was to investigate the correlations among ADC values, treatment response, and survival outcomes in individuals diagnosed with gliomas. This retrospective study included a total of 49 patients that underwent either stereotactic biopsy or maximal surgical resection. Histologically confirmed as Grade III or IV gliomas, all cases adhered to the 2016 and 2021 WHO classifications, with subsequent radio-chemotherapy administered post-surgery. Patients were divided into two groups: short and long survival groups. Baseline and follow-up MRI scans were obtained on a 1.5 T MRI scanner. Two ROI circles were positioned near the enhancing area, one ROI in the NAWM ipsilateral to the neoplasm and another symmetrically in the contralateral hemisphere on ADC maps. At follow-up there was a significant difference in both ipsilateral and contralateral NAWM between the two groups, -0.0857 (p = 0.004) and -0.0607 (p = 0.037), respectively. There was a weak negative correlation between survival and ADC values in ipsilateral and contralateral NAWM at the baseline with the correlation coefficient -0.328 (p = 0.02) and -0.302 (p = 0.04), respectively. The correlation was stronger at the follow-up. The findings indicate that ADC values in normal-appearing white matter (NAWM) may function as a prognostic biomarker in patients with diffuse gliomas.

Circulating thyroid hormones and clinical parameters of heart failure in men.

Heart failure (HF) is a multiple hormonal deficiency syndrome which includes alterations in the serum concentration of thyroid hormones (TH). This cross-sectional study enrolled 215 male patients hospitalised for acute HF. Data on cardiovascular risk factors, chronic medications, cardiac function assessed by echocardiography, and clinical parameters of HF were prospectively collected. The independent predictive association of TH with all investigated parameters of the HF severity were assessed. The patient's mean age was 74.4 years, 57.2% had arterial hypertension, 54.0% were consuming alcohol, and 42.3% were diabetics. Multivariate analysis revealed that total triiodothyronine (TT3) was an independent predictor of greater left ventricular ejection fraction (LVEF; ß = 0.223, p = 0.008), less progressed left ventricular diastolic dysfunction (LVDD; ß = - 0.271, p = 0.001) and lower N-terminal pro-brain natriuretic peptide (NT-proBNP; ß = - 0.365, p < 0.001). None of the TH other than TT3 was associated with LVDD or NT-proBNP, whereas free triiodothyronine (ß = - 0.197, p = 0.004), free thyroxine (ß = - 0.223, p = 0.001) and total thyroxine (ß = - 0.140, p = 0.041) were inversely associated with LVEF. The present study suggests that, among TH, serum TT3 level is most closely associated with echocardiographic, laboratory and clinical parameters of the severity of HF in men.

Prognostic factors of local recurrence and survival after curative rectal cancer surgery: a single institution experience.

The aim of our study is to evaluate the importance of prognostic factors, both tumor-related and therapy related, and their impact on local recurrence rate of rectal carcinoma. It is also important to evaluate impact of chemoradiotherapy (CRT) on local recurrence rate and survival. We used the data of 514 patients with rectal carcinoma treated at Clinic of surgery at University Hospital Centre in Osijek, during the period from 2000 to 2007. Routine follow-up was carried out until March of 2012 or death. Median life expectancy for all patients who underwent surgery was 98 months. 47% of patients with resection without residual tumor (R0) did not develop local recurrence after median of observation of 90 months. 5-year survival rate for patients with R0 resection was 76.4%. The patients who had preoperative serum levels of carcinoembryonic antigen (CEA) within the normal range (< 5 microg/mL) had a significantly better prognosis with 5-year survival of 75.8%, than patients with elevated levels who had 5-year survival of 46.5%. Tumor stage had great influence on survival and was defined by UICC TNM (International Union against Cancer, Tumor Node Metastases) classification, 7th edition. 5-year survival rate was (93.5% for stage I, 87.4% for stage II, 58.2% for stage III, 8.1% for stage IV). Patients with low grade differentiation tumors had 5-year survival rate of 73.5%, and those with high-grade had 38.2%. We have found that preoperative CRT significantly reduces the rate of local recurrence (5.3% vs. 14.1%), but patients who were treated with preoperative CRT did not appear to benefit significantly in terms of their long-term prognosis, because there was no difference in overall survival between the patients who received preoperative radiochemotherapy and those who did not receive it (66.2% vs. 67.8%). It was found that the R-classification, anatomical extent of tumor described by the TNM classification of the UICC, tumor grade, and preoperative CEA serum level were prognostic factors that influenced survival.

Mechanical bowel preparation in colorectal surgery.

The aim of this study was to assess the use of mechanical bowel preparation (MBP) and antimicrobial prophylaxis in elective colorectal surgery regarding still existing controversies. A prospective study of 85 patients undergoing elective colon and rectal surgery during 2 years period was performed, divided in two groups. Group A (N = 46) with patients who underwent mechanical bowel preparation, and group B (N = 39) patients without mechanical bowel preparation. We analysed: gender, age, preoperative difficulties, diagnostic colonoscopy, tumor localization, operation performed, pathohystological findings, Dukes classification, number of lymphonodes inspected, liver metastasis, other organ infiltrations, mean time of surgery, length of hospital stay, postoperative complications and mortality. Demographic characteristics, pathohystological findings, the site of malignancy, and type of surgical procedure did not significantly differentiate the two groups. The only significance revealed in mean time of surgery (138/178 minutes) in favor of patients with MBP (p = 0.017). Mechanical bowel preparation (MBP) for elective colorectal surgery is not advantageous. It does not influence radicalism of the procedure, does not decrease neither postoperative complications, nor hospital mortality.

Surgical treatment of liver echinococcosis--open or laparoscopic surgery?

Human echinococcosis remains a significant medical issue in endemic areas. Hydatid cysts can rupture, which is the most severe complication of echinococcosis as it can cause anaphylactic reaction and seeding of secondary cysts. Traditionally, hydatid cysts were evacuated by open surgical procedure in order to remove the entire cyst or by unroofing method, with evacuation of the cyst content. Recently, an increasing number of such operations are performed using laparoscopic approach. This study was prospectively conducted in a 5-year period, from 2004-2008. Altogether, 25 surgically treated patients were included in this study. Clinical examination, specific serological test, abdominal ultrasound and computed tomography were used for establishing diagnosis. Open surgery was initially performed in 17 patients and laparoscopic in 8. Three of those 8 patients required conversion to open surgery. Open pericystectomy was performed in 11 patients and laparoscopic pericystectomy in 3 patients. Open partial pericystectomy according to Papadimitriou was performed in 9 patients with hydatid cyst and laparoscopic partial pericistectomy in 2 patients. Our experience indicates that in the case of liver hydatid cyst disease, laparoscopic exploration, and if possible, laparoscopic pericystectomy or partial pericystectomy, should be performed in selected patients.

[Stercoral rectosigmoid colonic perforation with fecal peritonitis]. / Sterkoralna perforacija rektosigmoidnog kolona s fekalnim peritonitisom.

Chronic constipation can lead to fecal impaction and catastrophic complication such as colonic obstruction, perforation and fecal peritonitis. A case is reported of stercoral perforation of the rectosigmoid with pneumoperitoneum and fecal peritonitis. The patient was admitted for the signs of acute abdomen with pneumoperitoneum diagnosed on native radiological imaging.

[Laparoscopic versus open appendectomy: our experience and literature review]. / Laparoskopska ili otvorena apendektomija: nasa iskustva i pregled literature.

AIM: The controversy of the choice between open and laparoscopic appendectomy still remains. The benefits as well as disadvantages of laparoscopy are well known. METHODS: We designed a prospective 3-year clinical study (January 1, 2008-December 31,2010) with 123 patients operated on for acute appendicitis. They were prospectively divided into laparoscopic appendectomy (LA) group with 42 results and open appendectomy (OA) group with 81 results. The following parameters were analyzed: age, sex, preoperative leukocyte count, C-reactive protein (CRP) value, preoperative ultrasound finding (US), analgesic administration and histopathologic finding. The length of the operation, length of hospitalization (LOS) and complications were compared between the two groups, along with personal postoperative satisfaction estimated by telephone survey after discharge from the hospital. RESULTS: In 90% of cases, histopathology was positive for inflammation. CRP was determined in 42 (34%) patients preoperatively, with a mean value of 59; positive histopathology finding was recorded in 31 (74%) patients with increased preoperative CRP. US was performed in 68 (55%) patients; positive US was consistent with histopathology in 44 (65%) cases. The mean time of LA/ OA was 75/72 minutes. The only statistical difference was found for LOS: 4 versus 6 days (p < 0.01). CONCLUSION: LA and OA are comparable for the number of complications. The slight benefit of LA offers the surgeon free hand in decision when dealing with acute appendicitis needing urgent operation.

Clinical predictors of hyponatremia in patients with heart failure according to severity of chronic kidney disease.

BACKGROUND: Chronic kidney disease (CKD) has been associated with adverse clinical outcomes. Hyponatremia, a marker of illness severity and poor prognosis, is commonly exhibited in patients with CKD. METHODS: This cross-sectional study included patients hospitalized due to heart failure (HF). We used stepwise logistic regression to investigate the independent association of cardiovascular drugs, markers of HF severity, and baseline clinical characteristics with hyponatremia in three subgroups; normal renal function, mild-to-moderate CKD, and severe CKD. RESULTS: Of the 1232 patients, 38.6% were hyponatremic. Patients with severe CKD, compared to those with normal renal function and mild-to-moderate CKD, were more likely to be hyponatremic (47.1%, 34.4% and 36.6%, respectively; p ≤ 0.0001). Alcohol consumption, female sex, n-terminal pro-brain natriuretic peptide (NT-proBNP), hydrochlorothiazide (HCT), and mineralocorticoid receptor antagonist (MRA) use, or angiotensin II receptor I blocker (ARB) non-use were associated with hyponatremia in patients with normal renal function (p ≤ 0.03 in all cases). Current smoking, diabetes mellitus, NT-proBNP, loop diuretic dose, and MRA use were predictors in mild-to-moderate CKD (p ≤ 0.04 in all cases). ARB use, loop diuretic dose, and HCT use were predictors in severe CKD (p ≤ 0.03 in all cases). Non-use of dihydropyridine calcium channel blocker (CCB) was an independent predictor of hyponatremia in all CKD stages (p ≤ 0.04 in all cases). CONCLUSION: Apart from a firm favorable effect of CCBs, cardiovascular therapy should be carefully tailored to avoid hyponatremia in patients with cardiorenal syndrome.

Cystic echinococcosis of lung and heart coupled with repeated echinococcosis of brain--a case report.

Echinococcosis is rarely encountered as a cystic brain disease. In this article we are presenting a case of a young woman repeatedly operated due to echinococcosis of lung, heart and brain. Recurrent brain ecchinococcosis developed despite preoperative and postoperative albendazol therapy after first and combined therapy with albendazol and praziquantel after the second brain surgery. The mechanism of recurrence remains unclear (primary infestation, dissemination after spontaneous or intraoperative cyst rupture or new infestation).

Homocystinuria, a possible solution of the Akhenaten's mystery.

Pharaoh Amenophis IV (Amenhotep IV), also known as Akhenaten, is the most mysterious person in Egyptian history and he still remains the object of academic argues. This revolutionary king introduced a new concept in Egyptian religion and arts. It is still unexplained if images of him and his family were just an artistic outbreak from old Egyptian canon or an excellent paleopathological study. Several pathologic conditions were proposed to explain his appearance but neither is completely acceptable. We propose a different disease that he could have suffered of homocystinuria--lack of cysthationine-synthase. Our conclusion is that in comparison with up to date most convincing theory, that he was suffering of Marfan syndrome, our theory equally well explains his physical appearance but is better in explaining affecting and unaffecting of his relatives. This is the only theory about Akhenaten's disease that could be checked in the near future.

Laparoscopic repair of perforated peptic duodenal ulcer.

Although prevalence of peptic ulcer is decreasing, the number of peptic ulcer perforations appears to be unchanged. This complication of peptic ulcer is traditionally surgically treated. In recent years, a number of papers have been published where the authors managed perforated duodenal peptic ulcer in selected patients using laparoscopic approach. Laparoscopic treatment of perforated duodenal ulcer has been described as safe and advantageous compared to open technique but advantages are still not clear due to small number of cases in published studies. Based on these recommendations we decided to establish our own protocol for laparoscopic treatment of perforated peptic duodenal ulcer. In this prospective study we evaluated the first 10 patients in whom we performed laparoscopic repair of perforated duodenal ulcer. There were no conversions to open procedure and no early postoperative complications. The patients were contacted by phone a year after the operation, and all were satisfied with the operation and the appearance of postoperative scars. We regard laparoscopic repair of selected patients with perforated duodenal ulcer as a safe and preferable treatment.

Isolated splenic metastasis from colon cancer--case report and literature review.

Solitary splenic metastases are very rare and sporadic. There are several explanations for this low incidence of splenic metastasis including anatomical, histological and immunological features of the spleen. In this paper we present a case of 70-year-old man with no history of previous diseases who was first operated under the diagnosis of acute abdomen revealing perforated colon tumor of splenic flexure with no metastases at that time. Left hemicolectomy was performed followed by postoperative complications demanding a subtotal colectomy and ileostomy. Primary tumor was classified as Dukes (Astler-Coller)-C2, T4NIMO. Patient was referred to oncologist and received chemotherapy (5FU, Leucovorin). 5 months later continuity of the gut was performed by ileosygmoanastomosis. 2 years after first surgical procedure, a CT scan and abdominal ultrasound, followed by needle biopsy, showed isolated metastasis in spleen, so splenectomy was performed. Pathological findings revealed sharply bordered, partially necrotic tumor inside of spleen tissue, spreading to, but not reaching splenic hilum. Histology showed low to medium differentiated adenocarcinoma tissue with desmoplastic stromal reaction. There were no protrusions of tumor cells through spleen surface. In splenic hilum 4 tumor free lymph nodes were harvested. No additional chemotherapy was conducted. The latest follow up, a year after diagnosis of metastasis showed no signs of cancer disease. Review of the literature showed that long term survival and prognosis of isolated splenic colorectal metastasis after splenectomy are rather optimistic, although these are the cases of distant metastasis. Due to small number of cases reported in literature, definitive conclusions and/or guidelines for the treatment of isolated splenic metastasis cannot be given, but splenectomy and chemotherapy are preferable in the treatment, promising long term survival at least for metachronous metastasis.

[Laparoscopic partial pericystectomy of hepatic hydatid cysts --Papadimitriou operation: a case report]. / Laparoskopska parcijalna pericistektomija ehinokokne ciste jetre po papadimitriouu: prikaz bolesnika.

Operative treatment of hepatic hydatid cyst is technically demanding procedure. The method of choice is conservative treatment with Albendazolum followed by surgery. Open laparotomy or laparoscopic operation can be performed. We prefere laparoscopic exploration followed by laparoscopic total pericystectomy or laparoscopic partial pericystectomy. If laparoscopic operation is not possible due to technical reasons and patient safety, conversion to an open operation should be done, followed by total or partial pericystectomy. The case and our detailed technique of laparoscopic partial pericystectomy with biliostasis and omentoplasty is described. Laparoscopic operation is equally safe for the patient, yet with minor trauma and better aesthetic effect.

Furosemide and spironolactone doses and hyponatremia in patients with heart failure.

BACKGROUND: Hyponatremia, a marker of disease severity and prognosis, has been associated with various clinical factors and drug use, especially diuretics. METHODS: This observational prospective cohort study enrolled patients hospitalized at the University Hospital Center Split because of heart failure (HF). We investigated the association of clinical variables and cardiovascular drugs, including furosemide, hydrochlorothiazide, spironolactone, and their doses, with the presence of hyponatremia at admission. RESULTS: Of the 565 included patients, 32.4% were hyponatremic, 62.6% were males, and the mean age was 73.1 ± 10.6 years. In the univariate analysis, hyponatremic patients were more often current smokers (p = 0.01), alcohol consumers (p = 0.01), receiving spironolactone (p = 0.004) or combination of furosemide and spironolactone (p = 0.003). Patients who received 50 and 100 mg of spironolactone, compared to those receiving 25 mg (p < 0.0001), as well as patients who received 250 to 500 mg of furosemide compared to ≤240 mg (p = 0.001), were significantly more often hyponatremic. In the multivariate analysis, when diuretic doses were accounted for, furosemide doses of 250 to 500 mg (p = 0.009), spironolactone doses of 50 to 100 mg (p = 0.0003), increasing age (p = 0.03), diabetes mellitus (p = 0.02) and alcohol consumption (p = 0.04) were independently associated with hyponatremia. CONCLUSION: High doses of furosemide and spironolactone, or concomitant use of these diuretics, seem to be an important cause of hyponatremia in HF patients, particularly in combination with advanced age, diabetes and alcohol consumption. Diuretic dose reduction may help avoid hyponatremia and improve clinical status and prognosis in such patients.

Laparoscopic operation of hepatic hydatid cyst with intraabdominal dissemination--a case report and literature review.

Hepatic hydatid cysts are a serious medical problem in some regions like Mediterranean region. In Croatia 25-30 new cases of hepatic hydatid cysts are recorded each year In University Hospital Dubrava 7 patients with hepatic hydatid cysts were operated in 2008. Surgical approach recognizes open laparotomy and laparoscopy. The case and technique of laparoscopic operation of hepatic hydatid cyst in seventh segment and three disseminated intraabdominal cysts is described. Laparoscopy should be attempted even in complex cases with dissemination.

[Necrotizing fasciitis of the upper leg--case report and review of the literature]. / Nekrotizirajuci fascitis natkoljenice--prikaz bolesnika i pregled literature.

Necrotizing fasciitis is an uncommon but serious infection of skin, subcutaneous fat and fascia, characterised by rapidly spreading inflammation and associated with considerable morbidity and mortality. A 42-year-old man, with necrotizing fasciitis of the right upper leg, was hospitalized and treated by surgical debridement, along with intravenous administration of antibiotics, fluid resuscitation, correction of acidosis and electrolyte abnormalities. Four debridements were performed over four days. The patient developed septic shock with early stage of multiple organ failure, requiring one week in intensive care unit (ICU). Split-thickness skin grafts were placed on the fourth day after admission to the hospital. The patient was released to home care on the 21st day after admission, fully recovered. Necrotizing fasciitis is a life threatening infectious entity that requires rapid diagnosis, urgent extensive surgical debridement and tissue coverage as soon as possible to prevent secondary infections. ICU measures including intravenous antibiotics are often necessary, along with surgical treatment.
