RESUMO
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.

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.

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.

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.

A 56-year-old patient presenting necrotic ulcerations on the right leg was admitted to our Department for physical status deterioration. Clinically suspected diagnosis of pyoderma gangrenosum was confirmed histologically. Considering the association of pyoderma gangrenosum with several systemic diseases, extensive diagnostic evaluation was performed. Colonoscopy showed multiple ulcerations on descendent colon with stenosis of the shorter segment. Histologic examination confirmed the diagnosis of Crohn's disease. After systemic treatment with corticosteroids and wound management with proper wound dressings, complete epithelialization of ulcerations was accomplished.

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.

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.

Just like every other part of the organism, the skin ages as a result of the passage of time. That process is called chronologic or intrinsic aging. However, skin is also exposed to external insults, such as UV radiation, which is the most influential extrinsic factor in skin aging, causing so called photoaging or extrinsic skin aging. Photoaging is a cumulative process which depends on the degree of UV exposure and the skin type. It is much more visible in individuals with skin types I and II and, less prominent in dark-skinned population. Chronic sun exposure can result in numerous changes in human skin, particularly on the face, nape, and arms. Keratinocytes, melanocytes, fibroblasts, and endothelial cells are altered by UV radiation. Therefore, changes in photoaging include wrinkling, elastosis, actinic keratoses, irregular pigmentation, telangiectases, and the development of malignant skin tumours. In the last decades, important progress has been made in understanding molecular mechanisms of photoaging. It is a complex process in which UV radiation has effects on numerous molecular processes that damage the skin, especially connective tissue of the skin. These processes include cell surface receptors, certain signal transduction pathways, transcription factors and, various enzymes involved in the synthesis and degradation of the dermal elements. Initial process in the activation of this process is UV-induced generation of the reactive oxygen species, which can also directly damage cell's DNA, membrane and proteins. Most of alterations found on the photoaged skin had formerly been considered to be caused by UVB wavelengths. However, a number of recent studies have demonstrated that UVA can also cause burning, elastosis, and skin cancer.

Nevoid melanoma is a rare form of melanoma histologically resembling benign melanocytic nevi and may be overlooked in routine histological sections. Authors are presenting a case of a 31-year-old woman who presented with bizarre pigmented skin lesions in the area of the postoperative scar on the back where, 6 years earlier, a "nevus pigmentosus epidermo-dermalis" was excised and hystologically confirmed in outer institution. The lesions were surgically removed and histopathological findings were characteristic for nevoid melanoma. Additionally, specimen of primary removed lesion was reexamined and primary nevoid melanoma was then recognized, therefore indicating that the lesions our patient presented with are nevoid melanoma recidivisms. Extensive diagnostic procedures showed no signs of melanoma dissemination. Three months later, the patient returned for consultation and presented with two new brownish-pigmented papules in the area of the new postoperative scar. The lesions were excised and new nevoid melanoma recidivism was confirmed. The patient remained under the regular follow up and, almost 9 years after the removal of primary nevoid melanoma, followed by two cutaneous recidivisms, remains disease-free. This case aims to highlight the problematic area in the analysis of pigmented skin lesions where nevoid melanoma represents one of the clinical and pathological diagnostic challenges.

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.

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.

In the cases of incarcerated Richter hernia the diagnosis is difficult especially for obese patients. Laparoscopic diagnostics and desincarceration, can be combined with mini laparotomy in lieu of bowel resection and open hernioplasty, or conversion to classic laparotomy and open hernioplasty. Here is presented a case of incarcerated Richter inguinal hernia managed through the combination of laparoscopy, mini laparotomy for segmental bowel resection and open hernioplasty.

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.

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.

Dermatosurgery has become ever more popular and important in recent years, mostly due to the increasing prevalence of skin malignancies. It also encompasses a wide variety of methods to remove or modify skin tissue for numerous cosmetic reasons. Nowadays, many dermatologists provide complete dermatologic care for their patients, including surgery. Therefore, it is important to be aware of the possible complications and to be able to manage them properly. Complications in cutaneous surgery are not very often, but they can be serious and worrisome including bleeding, infections, allergic reactions, syncope, wound dehiscence, necrosis, and others. In this article special attention is given to bleeding, which is the most common complication in this field. The best way to reduce the number of possible complications is to recognize patients at risk. Thus, complete history and physical examination are required before performing any dermatosurgical operation.

Photoallergic dermatoses are skin lesions following sun exposure, characterized by activation of immunological mechanisms, involving photosensitizers and photoallergens that can cause photosensibilization in some individuals. In this group of disorders, photoallergic contact dermatitis should be accentuated. It manifests as contact allergic dermatitis on sun-exposed skin areas, following direct contact with photoallergens during UV exposure (predominantly UVA). Under influence of light, photosensitizers get activated, followed by fusion with cutaneous proteins which renders them to complete antigens, and consequential initiation of immunological mechanisms with resulting pathological skin lesions. The most common photoallergens are: sulfonamide antibiotics, phenothiazines, and halogenated salicylanilides. Photoallergic dermatoses are comprised of several disorders, although the causative photoallergen remains unknown (e.g. solar urticaria, polymorphous light eruption and hydroa vacciniforme). Solar urticaria is a rare, acute urticarial reaction on both sun-exposed and covered skin areas, which appears soon after exposure to sun or artificial lighting. Polymorphous light eruption is a relatively common polymorphous skin eruption, which usually appears in spring. Its pathogenesis is unknown, presumably photoallergic reaction. Hydroa vacciniforme is a rare photodermatosis of unknown etiology, which usually presents in summer-time. It is characterized by vesicobullous eruptions, with residual nonesthetic varioliform scarring.

Hair is a very important for our self-confidence as well as a very important part of appearance and self-concept. It reflects our personality and hair loss or hair damages are considered aesthetic imperfections and social handicap. Outward part of the hair is a "hair shaft" keratin fiber structure sensible to external effects whether they are mechanical, physical or chemical. Excessive sun exposition is the most frequent cause of hair shaft's structural impairment. Photochemical impairment of the hair includes degradation and loss of hair proteins as well as degradation of hair pigment. Hair protein degradation is induced by wavelengths of 254-400 nm. UVB radiation is responsible for hair protein loss and UVA radiation is responsible for color changes. Absorption of radiation in photosensitive amino acids of the hair and their photochemical degradation is producing free radicals. They have adverse impact on hair proteins, especially keratin. Melanin can partially immobilize free radicals and block their entrance in keratin matrix. It also absorbs and filters adverse UV radiations. Therefore melanin is important for direct and indirect protection of hair proteins. Protecting the cuticle is very important for keeping hair shaft's integrity. One can achieve that by avoiding noxious impacts or by implementation of hair care products with UV filters. Nowadays major studies and researches are conducted in order to create hair care products that prevent hair damage.

Liver abscess still represents a significant clinical entity with mortality rates of up to 10%. Traditional treatment of liver abscesses is open surgical treatment. Recently, percutaneous and laparoscopic drainage has been increasingly used. Still, in spite of these relatively novel techniques and improved imaging, liver abscess can sometimes be difficult to diagnose or treat. Here we present two cases of chronic liver abscess treated at our department. First patient was twice hospitalized in other hospitals without reaching definitive diagnosis. He was admitted at our department because of clinical presentation of sepsis, and definitive diagnosis of liver abscess was established only during open surgery. Second patient was admitted after laparoscopic drainage and repeated percutaneous drainage had failed to resolve his symptoms. In both cases, liver segment resection led to complete healing. These cases indicate that chronic liver abscess can still present a diagnostic and therapeutic challenge.
