Lateral frontal galeal-cutaneous flap for reconstruction after orbital exenteration for advanced periorbital skin cancer.

BACKGROUND: Orbital exenteration (OE) is one of the most disfiguring procedures leading to significant deformity. Defect reconstruction is challenging, especially in elderly patients. Herein, experiences with orbital exenteration and primary reconstruction with lateral frontal galeal-cutaneous flap based on superficial temporal artery were reviewed. METHODS: Data on patients treated for nonmelanoma skin cancer invading the orbit during a 10-year period were analyzed. The patient demographics, tumor features, reconstructive techniques used, complications, and survival were recorded with a median follow-up of 27.5 months. RESULTS: Included in the study were 26 patients in whom OE was performed, comprising 14 males and 12 females, with a mean age of 75.29 years (range: 61-87). The majority of the patients were treated for basal cell carcinoma with medial cantus as the primary site. All of the defects were closed using a lateral frontal galeal-cutaneous flap based on the superficial temporal artery, and in 2 patients, a temporalis muscle pedicle flap was used as an additional flap for reconstruction of the orbital roof in order to separate the brain from the empty orbit, and it was then covered with the same galeal-cutaneous flap. In 19 patients, the frontal area was closed primarily, and in 7 patients, skin graft was used for the secondary defect. There was no flap loss. Tumor-related death was registered in 3 patients (inoperable recurrent tumors) (11.5%), 7 died from complications that were unrelated to the tumors (2 were operated for recurrent orbital tumors), and 16 survived. DISCUSSION: The preferred method for reconstruction after OE at our university affiliated center is lateral frontal galeal-cutaneous flap based on the superficial temporal artery. Flap harvesting is simple, safe, and obtains enough tissue to cover the defects, even after extended exenteration. The complication rate is low. The simultaneous use of this flap with pedicle temporalis muscle flap is suggested only for reconstruction of the scull base after anterior cranial fossa resection.

Head and neck cutaneous melanoma: 5-year survival analysis in a Serbian university center.

BACKGROUND: Head and neck melanoma (HNM) is specific from the anatomical and etiopathogenetic aspects. In addition to morphopathological parameters, rich vascularization and lymphatic drainage of the head and neck affect the occurrence of lymphogenic and hematogenous metastases, as well as the metastases on both sides of the neck. METHODS: A retrospective cross-sectional study included cutaneous melanoma patients who underwent surgery at a clinical center over a 10-year period. The clinical follow-up was at least 60 months. The Kaplan-Meier method was used for the survival analysis. The predictor effect of certain independent variables on a given dichotomous dependent variable (survival) was measured by the Cox regression analysis. RESULTS: The analysis of demographic and clinical characteristics of 116 patients with HNM revealed that there was no statistically significant difference in age and gender in the total sample. Thirty-three (28.45%) patients were already in stage III or IV of the disease at the first examination, which affected the overall survival rate. The overall 5-year survival was 30.2%. No statistically significant difference in 5-year survival was found in relation to age and location. The period without melanoma progression decreased progressively in the advanced stage. Forty-nine patients (42%) underwent surgery for lymphogenic metastases in the parotid region and/or neck during the follow-up. CONCLUSIONS: Patients with HNM included in this study frequently presented an advanced stage of the disease at the first examination, which is reflected in a low rate of 5-year survival. Early diagnosis and adequate primary treatment can ensure longer survival.

Quality of Life Indicators in Patients Operated on for Breast Cancer in Relation to the Type of Surgery-A Retrospective Cohort Study of Women in Serbia.

Background and objectives: Quality of life (QoL) after breast cancer surgery is an important public health issue. The aim of this study was to determine the relationship between the levels of perceived quality of life in patients operated on for breast cancer in relation to the type of surgery, using the standardized questionnaires. Materials and Methods: We assessed 425 women after surgery for breast cancer. The assessment included the application of the WHOQOL-bref (The World Health Organization Quality of Life-Bref), and FACT-B (Functional Assessment of Cancer Therapy-Breast) questionnaires. The statistical analysis of the data included multiple linear regression and correlation tests. Results: Multiple linear regression analysis found that education, existence of comorbidities, time elapsed since surgery, and type of surgery were significant predictors of overall quality of life. Women's overall quality of life and general health has increased by 0.16 times for each subsequent year of surgery, and by 0.34 times for each subsequent higher education level. Breast-conserving surgery or mastectomy with breast reconstruction were statistically significant (ß = 0.18) compared to total mastectomy. Conclusions: There is a significant difference in the quality of life perceived by patients in whom the breast has been preserved or reconstructed in relation to patients in whom total mastectomy has been performed.

Pancreatic pseudocyst with spontaneous cutaneous fistulization: Case report.

RATIONALE: Pancreatic fistula occurs as a result of pancreatic duct disruption during acute pancreatitis. An external or pancreatico-cutaneous fistula is defined as a leakage of pancreatic secretion through an abdominal wound or previously inserted drain. If the extravasated pancreatic juice is walled-off by the fibrous or granulation tissue, a pseudocyst is formed. Fistulization of the pancreatic pseudocyst into the different surrounding hollow viscera is reported. However, we present a patient with spontaneous cutaneous fistulization of the pancreatic pseudocyst into the lumbar region successfully treated conservatively. Such an extremely rare presentation is only reported twice and thus highly unexpected during the follow-up of patients after recovery from acute pancreatitis. PATIENT CONCERNS: The patient presented with 5-days intermittent fever and a tender, fluctuant, and erythematous swelling of the left lumbar paravertebral region with black necrotic skin spot on the top of it. DIAGNOSES: Abdominal computed tomography scan revealed retroperitoneal pseudocyst originating from the pancreatic body and tail and extending to the left flank. INTERVENTIONS: Incision of the swelling evacuated dark amylase rich fluid. Colostomy disc and bag were applied to collect further spontaneous outflow of pseudocyst content. OUTCOMES: Symptoms instantly resolved and the patient was managed conservatively with ambulatory follow-up of the daily volume of fistula discharge. Over the next 37 days daily fistula output gradually reduced to nil with the spontaneous closure of the external skin fistula opening. LESSONS: Frequent follow-ups of patients after severe acute pancreatitis are necessary for early detection and timely successful treatment of pancreatic pseudocysts with such unusual and rare presentation.

Comparison of recurrence patterns of colorectal cancer in laparoscopic and open surgery groups of patients: A meta-analysis.

PURPOSE: The purpose of this meta-analysis was to evaluate differences between laparoscopic and open surgery and also the development of local and distant colorectal cancer (CRC) recurrences in treated patients. METHODS: 2,058 cases treated with laparoscopic surgery and 2,365 cases with open surgery from 20 included studies were analyzed, using the random-effects model. The mean difference and odds ratio (OR) with 95% confidence interval (95%CI) were calculated. An overall and a subgroup analysis was performed according to the type of cancer - colon or rectal, and we registered the operating time, number of dissected lymph nodes and need for intraoperative blood transfusion in the laparoscopic and open surgery group of patients. RESULTS: The operating time in the laparoscopic surgery group was significantly longer than in the open surgery group (mean difference 38.23 min). There was no significant differences in the number of dissected lymph nodes between the two groups when we pooled data for treatment of CRC (p=0.16). The OR of overall and local recurrences was significantly decreased in patients in the laparoscopic surgery group compared to those in the open surgery group (OR 0.83; 95%CI 0.70-0.98; p=0.03) and (OR 0.70; 95%CI 0.50-0.97; p=0.03), respectively. No significant differences were found between patients who underwent laparoscopic surgery and those that had open surgery for distant recurrences after CRC treatment. CONCLUSIONS: There was statistically significant difference between laparoscopic or open surgery and development of local and overall CRC recurrences.

Presentation of pericardial hydatid cyst as acute cardiac tamponade.

We report a case of a 47-year-old man with isolated pericardial hydatid cyst (without myocardial involvement) that presented as acute pericardial tamponade. After initial investigation and transthoracic echocardiography, emergent pericardial drainage was performed for downgrading the urgency of a definitive treatment for a hydatid cyst. A computed tomography examination after the pericardial drainage showed a pericardial cyst without heart muscle involvement, making the treatment possible through anterior thoracotomy and without performing cardiopulmonary bypass. Complete surgical removal of the cyst was performed. The postoperative course was uneventful. The patient received postoperative albendazole treatment. He remained asymptomatic and no recurrence was observed during a 1-year follow-up period.

Primary reconstruction of neck defect after excision of metastatic melanoma of unknown primary site with regional pectoral myocutaneous flap.

Introduction: Metastatic melanoma of unknown primary (MMUP) is already a well described oncologic phenomenon in the literature, whereas tissue defects' reconstructions on the neck region always present a challenge for the reconstructive surgeon. Two cases of giant metastatic, skin infiltrative neck tumor masses are presented. In both cases MMUP was diagnosed. Both intraoperative tissue defects were reconstructed using pectoralis major (PM) regional flap. Outline of cases: The first patient was admitted with giant tumor mass on the right side of the neck. The fast growing mass appeared two months prior to the admission. Thorough examination showed no signs of primary tumor. Removal surgery was performed and the defect was reconstructed using the PM musculocutaneous flap. The second patient was admitted with large tumor mass on the left side of the neck. Thorough examination displayed no signs of any primary tumor. After the excision, the tumor mass and subsequent neck dissection, reconstruction followed, using the pedicled PM muscle flap and partial thickness skin transplants. There were no major complications in either case. The histopathological examinations presented metastatic melanoma diagnoses. Conclusion: Clinical outcome of MMUP described in literature is rather variable. Different studies have shown that prognosis in patients with MMUP is better than that in patients with diagnosed primary melanoma with metastatic disease. Therefore, the best initial course of action in those cases would be surgery, according to oncological principles, if possible. Neck defects' reconstructions should fulfill both functional and esthetic demands. Due to the reliability and low cost of the procedure, PM regional flap presents a very good and trustworthy reconstruction modality.

Addition of blood to a phycogenic bone substitute leads to increased in vivo vascularization.

The present study aimed to analyze the effects of the addition of blood to the phycogenic bone substitute Algipore(®) on the severity of in vivo tissue reaction. Initially, Fourier-transform infrared spectroscopy (FTIR) of the bone substitute was conducted to analyze its chemical composition. The subcutaneous implantation model in Balb/c mice was then applied for up to 30 d to analyze the tissue reactions on the basis of specialized histochemical, immunohistochemical, and histomorphometrical methods. The data of the FTIR analysis showed that the phycogenic bone substitute material is mainly composed of hydroxyapatite with some carbonate content. The in vivo analyses revealed that the addition of blood to Algipore(®) had a major impact on both angiogenesis and vessel maturation. The higher vascularization seemed to be based on significantly higher numbers of multinucleated TRAP-positive cells. However, mostly macrophages and a relatively low number of multinucleated giant cells were involved in the tissue reaction to Algipore(®). The presented data show that the addition of blood to a bone substitute impacts the tissue reaction to it. In particular, the immune response and the vascularization were influenced, and these are believed to have a major impact on the regenerative potential of the process of bone tissue regeneration.

The Infraorbital Artery in Fetuses: Clinical Relevance in Perforator Flap Surgery.

INTRODUCTION: The reconstruction of soft tissue detects in mid facial region are highly demanding. Most challenging region are nasal alla. For full thickness nasal alla defects most authors use nasolabial flap based on facial/angular arcade, but for recidivans tumors the infraorbital perforator flap is a good solution. AIM: The aim of our research was to analyze the number and the course of the infraorbital artery terminal branches. MATERIAL AND METHODS: Material was 60 fetal hemifacial specimens of different gestational ages. Fetuses were fixed in 10% formalin and arterial blood vessels were injected with Micropaque solution (barium sulfate). Samples were further processed by Spalteholz technique, their images captured with digital camera and analyzed. Infraorbital artery was constant artery and had 2 to 4 terminal branches supplying infraorbital region. The majority of its terminal branches were characterized with descending course. Reach anatomical network of infraorbital artery made anastomoses with facial artery. CONCLUSION: Perforator flap based on infraorbital artery had well defined vascular supply with numerous soft tissue branches, which qualify this flap as safe solution for nasal reconstruction.

Reconstruction of full thickness abdominal wall defect following tumor resection: a case report.

INTRODUCTION: Reconstruction of a full thickness abdominal wall defect is a demanding procedure for general and also for plastic surgeons, requiring vigorous planning and reconstruction of three layers. CASE OUTLINE: We present a case of a 70-year-old patient with a huge abdominal wall tumor with 40 years evolution. Surgery was performed under general anesthesia. Full thickness abdominal defect appeared after the tumor resection. Reconstruction followed in the same act. The defect was reconstructed using a combination of techniques, including omental flap, fascia lata graft, local skin flaps and skin grafts. After surgery no major complications were noted, only a partial skin flap loss, which was repaired using partial thickness skin grafts. The final result was described by the patient as very good, without hernia formation. CONCLUSION: Omenthoplasty, abdominal wall reconstruction in combination with free fascia lata graft and skin grafts can be one of good options for the reconstruction of full thickness abdominal wall defects.

Second look procedure for large burn defect by banana peel pericranial flap based on one artery.

INTRODUCTION: Scalp and calvarial defects may result from trauma, thermal or electrical burns, resection of benign or malignant tumors, infections or radionecrosis. Reconstruction of large scalp defects is a demanding procedure. The reconstructive "ladder" are applicable to scalp and calvarial defects reconstruction. CASE OUTLINE: A 68-year-old female was admitted to our clinic due to the nine-day old scalp burn wound, incurred under unclear circumstances. Third degree burn wound affected the left frontal-parietal, temporal and part of the occipital region with carbonification of the whole left ear lobe.The treatment was carried out in two stages. Radical full thickness necrectomy of the scalp was performed, the defect margins were curetted to the active bleeding, and the ear lobe was amputated.The defect sized 23 x 15 cm was reconstructed using the"banana peel"transposition galea-cutaneous flap from the remainder of the scalp, which was based only on the right occipital artery.Two months after the surgery the appearance was satisfactory, and all wounds were healed. CONCLUSION: Designing of large-scale flaps is very hazardous, especially in elderly people. Scalp reconstruction based on one artery has to be planned in detail and performed when the possibility of complication is reduced to minimum. Our case report underlines possible reconstruction as delayed procedure even with the exposed bone (second look procedure), as well as the reconstruction of half scalp with the local flap based on one pericranial artery.

Catastrophic necrotizing fasciitis after blunt abdominal trauma with delayed recognition of the coecal rupture--case report.

Necrotizing fasciitis (NF) is a rare bacterial infection with dramatic course, characterized by widespread necrosis of the skin, subcutaneous tissue, and superficial fascia which can often lead to death. We present a case of a 27-year-old male with NF. One day after experiencing blunt abdominal trauma caused by falling over bike handlebars, the patient was admitted to a regional hospital and treated for diffuse abdominal pain and large hematoma of the anterior abdominal wall. Due to worsening of general condition, he was referred to our hospital the following day and operated on urgently. Surgery revealed rupture of the coecum with peritonitis and abdominal wall infection. After surgery, fulminant necrotizing fasciitis developed. Antibiotics were prescribed according to wound cultures and subsequent necrectomies were performed. After 25 days, reconstruction of the abdominal wall with skin grafts was obtained. Despite all resuscitation measures including fluids, blood transfusions, and parenteral nutrition, lung infection and MODS caused death 42 days after initial operation. Blunt abdominal trauma can cause the rupture of intestine, and if early signs of peritoneal irritation should present, emergency laparotomy should be performed. Disastrous complication are rare but lethal.

Comparative analysis of autodermal graft and polypropylene mesh use in large incisional hernia defects reconstruction.

BACKGROUND: Large defects of the abdominal wall caused by incisional hernia still represent a challenging problem in plastic, reconstructive, and abdominal surgery. For their successful tension-free repair a proper selection of reconstructive material is essential. In the last decades, the use of synthetic meshes was dominant while biological autodermal grafts were rarely used. The aim of the study was to comparatively analyse efficacy and safety of autodermal graft and polypropylene mesh in surgical treatment of large abdominal wall defects. METHODS: This prospective comparative clinical study enroled 40 patients surgically treated for large incisional hernia repair in a 10-year period. The patients were divided into two equal groups consisting of 20 subjects and treated either by biological autodermal graft or by synthetic polypropylene mesh. The surgical techniques of reconstruction, duration of surgery, the occurrence of early, minor, and major (severe) and delyed complications and hospital stay were analysed. The average follow-up took 2 years. RESULTS: Statistically significant differences in demographic characteristics of patients and in size of defects were not found. The surgical technique of reconstruction with an autodermal graft was more complicated. The duration of surgery in patients treated with autodermal grafts was significantly longer. There was no statistically significant difference regarding occurrence of early, minor postoperative complications and hospital stay in our study. Two severe complications were registered in the synthetic mesh group: intestinal obstruction and enterocutaneous fistula. The recurrence rate was 10% in the autodermal graft group and 15% in the group with a synthetic mesh. CONCLUSION: Tension-free repair of large incisional hernia with autodermal grafts was unjustly neglected despite the fact that it is safe and effective. It can be applied in all cases where synthetic mesh are not indicated (presence of infection, immunodeficient patients, after radiotherapy). They are especially important in war surgery and in lack of funds when commercial grafts cannot be purchased.

Similarities and dissimilarities of the blood supplies of the human sciatic, tibial, and common peroneal nerves.

The aim was to investigate the arterial supply of the sciatic, tibial, and common peroneal nerves. Thirty-six lower limbs of 18 human fetuses were studied. The fetuses had been fixed in buffered formalin and the blood vessels injected with barium sulfate. Fetal age ranged from 12 to 28 weeks of gestation. Microdissection of the fetal lower extremities was done under ×5 magnifying lenses. The sciatic nerves of 10 lower extremities were dissected and excised and radiographs taken. The extraneural arterial chain of the sciatic nerve was composed of 2-6 arterial branches of the inferior gluteal artery, the medial circumflex femoral artery, the perforating arteries, and the popliteal artery. The extraneural arterial chain of tibial nerve was composed of 2-5 arteries, which were branches of the popliteal, the peroneal, and the posterior tibial arteries. Radiographs showed the presence of complete intraneural arterial chains in the sciatic and tibial nerves, formed from anastomosing vessels. Dissection showed that, in 97.2% of the specimens, the common peroneal nerve was supplied only by one popliteal artery branch, the presence of which was confirmed radiologically. The sciatic and tibial nerves are supplied by numerous arterial branches of different origins, which provide for collateral circulation. In contrast, the common peroneal nerve is most frequently supplied only by one elongated longitudinal blood vessel, a branch of the popliteal artery. Such a vascular arrangement may make the common peroneal nerve less resistant to stretching and compression.

Single stage turn in perforator infraorbital artery island flap for nasal ala reconstruction.

BACKGROUND: The reconstruction of fullthickness nasal alla defects is challenging procedure. Use of local flaps is acceptable approach. Flap based on infraorbital artery could be used for primary reconstruction of nasal ala defects. METHODS: The prospective study include consecutive series of 15 patients with advanced skin carcinoma of the nasal ala and medial cheek staged T4 by TNM, in whom the turn in infraorbital flap was used. The patient characteristics, type of carcinoma and complications were analyzed. RESULTS: The turn in infraorbital flap was used mostly in male patients (80%), mean age 64 years. The basal cell skin carcinoma was found in 60%. Skin layer was skin grafted. All flaps survived, but in one case a partial wound dehiscence in one partial skin graft loss was found, and in two patients partial nasal obstruction occurred. These three complications were solved as secondary procedures under local anesthesia. CONCLUSION: Full-thickness defect of the nasal ala can be properly reconstructed using flap based on infraorbital artery providing exceptional esthetic and functional results, as single stage procedure.

A unique case of hereditary bilateral segmental neurofibromatosis on the face.

Segmental neurofibromatosis is a rare clinical finding generally with no family history and facial involvement. There are four subtypes of segmental neurofibromatosis: true segmental, localized cases with deep involvement, hereditary segmental and bilateral segmental neurofibromatosis. Here we report three patients from the same family (father, son and granddaughter) with segmental bilateral neurofibromatosis on the face. This form has not been noticed in the literature.

[Unusual case of successful hand replantation with bad functional outcome: a case report].

INTRODUCTION: Traumatic hand amputation is a very severe and rare injury. Replantation and revascularization surgery requires the existence of specialized centres and well-educated teams of microsurgeons. In places where there are no such specialized centres for this kind of surgery, traumatic hand amputation is a major concern and quite a challenge, and a successfully performed replantation is a great accomplishment. CASE OUTLINE: We report a case of a successfully survived replanted hand in a 35-year-old male patient with unfortunately bad end result of the treatment. The patient with the amputated left hand (disarticulation) had a surgery 4 hours after injury. The urgent surgical procedure required a debridement, the excision of the first row of the carpal bones, external fixation of the wrist, vascular anastomoses, nerve repair, tenorrhaphy, skin sutures and decompression skin incisions.The successful operation did not have a successful post-operative course due to the patient's psychiatric problems and lack of rehabilitation at the psychiatric institution where the treatment was continued. CONCLUSION: Successful surgical performance can unfortunately be ruined due to inadequate further treatment course or the wrong selection for such a demanding surgery. The survival of the amputated hand can be achieved surgically, but achieving refunctioning does not always depend on surgery. It also depends on the very patient, his motivation, rehabilitation, as well as on the proper selection for such a demanding and complex surgical procedure.

Application of sentinel lymph node biopsy in cutaneous basosquamous carcinoma.

Basosquamous carcinoma of the skin is a relatively rare cutaneous neoplasm that has significant metastatic potential and a metastatic rate greater than that of basal cell and squamous cell carcinoma. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a 63-year-old man after identification of basosquamous carcinoma. Sentinel lymph node biopsy, which is a standard tool to detect regional lymphatic metastasis in cutaneous melanoma, has been rarely employed to detect lymphatic metastasis of basosquamous carcinoma. The approach was successful in detecting a regional lymphatic metastasis of two nodal basins with minor morbidity. Sentinel lymph node biopsy may be useful for certain high-risk lesions of basosquamous carcinoma.

[Incidence of lip and palate clefts in children in Nis from 1990 to 2007].

INTRODUCTION: Cleft lip and palate is a complex congenital anomaly of the orofacial system in children. OBJECTIVE: The aim of this study was to determine the incidence of live-born children with cleft lip and/or palate compared to the total number of children born in the period from January 1, 1990 to December 31, 2007. METHODS: Epidemiological investigation was based on the records of live-born children at the Hospital of Gynaecology and Obstetrics of the Clinical Centre Nis. The study included 61,116 live-born children, i.e. 56,905 full-term babies. RESULTS: The total number of registered clefts during the investigation period was 43 (22 boys and 21 girls). The most frequent were the secondary palate clefts (44.2%); combined cleft were present in 34.9%, while primary palate clefts were reported in 20.9%. In respect to the season and order of birth, there was no statistically significant difference in the frequency of the primary, secondary and complete palate clefts. The age of mothers was not identified as a risk factor for the occurrence of cleft lip and palate. CONCLUSION: In the studied period, 43 children were born with the cleft lip and/or palate, equally in boys as in girls. The secondary palate clefts were most frequent. The season and order of birth had no statistical influence on the occurrence of this anomaly.
