RESUMO
BACKGROUND AND AIMS: Although declining, cystic echinococcosis is still a serious public health issue in Greece. This study evaluated the clinical features, management, and short-term outcome of patients with complicated liver echinococcosis. MATERIAL AND METHODS: A total of 227 patients who were operated on for 322 echinococcal cysts of the liver were retrospectively evaluated. Patients were divided into those with complicated disease (53.7%) and those with noncomplicated disease (46.3%). Intrabiliary rupture (34.4%), cyst infection (32.7%), and their combination (24.5%) were the most common complications. Demographic characteristics, previous hydatid cyst surgery, cyst multiplicity and location, presenting symptoms and signs, types of complicated disease, operative procedures performed, postoperative complications, and hospital stay were assessed. RESULTS: Patient demographics and cyst characteristics demonstrated no significant difference between the two groups. The complicated disease group had significantly more pronounced clinical presentations and higher postoperative morbidity. Choice of surgical procedure depended upon cyst location and surgeon preference. Both conservative and radical procedures were performed, supplemented with additional management of the biliary tree when indicated. CONCLUSIONS: Complicated liver echinococcosis demonstrates several distinct features that differentiate it from the noncomplicated disease. Frequently severe clinical manifestations, complexity of surgical management, and the increased postoperative complications characterize complicated liver echinococcal disease.

BACKGROUND: Intraperitoneal adhesions are a common problem in abdominal surgery. The aim of this study was to compare the effectiveness of Statofilm, a novel antiadhesive film based on cross-linked carboxymethylcellulose and atorvastatin, with that of sodium hyaluronate-carboxymethylcellulose (Seprafilm(®)) in the prevention of postoperative intraperitoneal adhesions in rats. METHODS: One hundred male Wistar rats underwent a laparotomy and adhesions were induced by caecal abrasion. The animals were allocated to five groups: a control group with no adhesion barrier, Seprafilm(®) group, placebo group with a film containing carboxymethylcellulose without atorvastatin, and low- and high-dose groups with films containing carboxymethylcellulose and atorvastatin 0·125 and 1 mg per kg bodyweight respectively. Adhesions were classified by two independent surgeons 2 weeks after surgery. Caecal biopsies were obtained for histological evaluation of fibrosis, inflammation and vascular proliferation. RESULTS: All antiadhesive film groups (Seprafilm(®), placebo, low-dose and high-dose) had statistically significant adhesion reduction compared with the control group (P < 0·001, P = 0·015, P < 0·001 and P < 0·001 respectively). The low-dose Statofilm was superior to Seprafilm(®) in terms of adhesion prevention (P = 0·001). Adhesions were present in three-quarters of rats in the Seprafilm(®) group, but only one-quarter in the low-dose Statofilm group. CONCLUSION: The data suggest that the newly developed adhesion barrier Statofilm has better results than Seprafilm(®) in preventing postoperative adhesions in rats. A low-dose atorvastatin-containing film, such as Statofilm, could be evaluated for future clinical application.

BACKGROUND: Bevacizumab is a monoclonal antibody targeted at vascular endothelial growth factor (VEGF) to treat advanced colorectal cancer as well as other malignancies, but the ideal time point for its administration in patients scheduled for surgery is not well defined due to serious concerns regarding possible side effects on wound healing. Therefore, we conducted an experimental study in rats to clarify this issue. METHODS: Four groups of 10 Wistar rats each underwent a 4-cm midline laparotomy and closure of the wound in 2 layers. In the treatment groups (A and B), bevacizumab (Avastin(®)) received a single dose of 5 mg/kg i.p., and an equal amount of saline was given to the control groups (C and D). Groups A and C were sacrificed on the 7th postoperative day, and groups B and D on the 14th postoperative day. Wounds were inspected by two independent observers upon sacrifice and results were recorded; wound tissues were sent for histology to assess the degree of fibrosis and measurement of tissue hydroxyproline levels. Serum levels of endothelin-1, C-reactive protein, pro-oxidant/antioxidant balance and carbonylated proteins were also determined. For statistical analysis, the Mann-Whitney U test was used. RESULTS: Wound healing did not differ among groups both on the 7th and the 14th postoperative days, and there was also no significant difference regarding the degree of inflammation, fibroblast proliferation and collagen synthesis, as well as hydroxyproline and biochemical marker levels among the groups. CONCLUSIONS: Intraperitoneal bevacizumab administered intraoperatively does not significantly affect abdominal wound healing in rats.

BACKGROUND: elderly patients are steadily becoming a growing part of the population. The aim of this study is to evaluate the outcome of open inguinal hernia repair in patients aged over 65 years. METHODS: from January 1999 to December 2008, a total of 719 patients underwent open tension-free inguinal hernia repair with mesh-plug; 301 among them were ≥ 65 years old. RESULTS: elderly patients had a mean age of 72.4 years (women 3.3%), while the mean age of younger patients was 48.7 years (women 5.7%). According to the ASA score, patients aged ≥ 65 years were at significantly higher risk than the younger patients. Spinal anesthesia was used most frequently in both groups. No significant differences were found in postoperative pain, mortality and recurrence. Morbidity and hospital stay were significantly higher in patients aged ≥ 65 years. CONCLUSIONS: open hernia repair in the elderly is safe and well tolerated, but it is associated with higher morbidity and longer hospitalization.

BACKGROUND: Sigmoidorectal endometriosis accounts for 70% of the cases of intestinal endometriosis. Symptoms are non-specific, frequently resembling adenocarcinomas. CASE: A 45-year-old woman complaining of recurrent rectal bleeding underwent colonoscopy in which a rectal polypoid mass was found. She underwent anterior rectosigmoidectomy and the histological examination of the resected bowel revealed rectal endometriosis with lymph node involvement. CONCLUSION: Lymphatic infiltration of epicolic lymph nodes raises questions about the benign nature of this presumed innocent disease.

BACKGROUND AND AIM: To present our experience with unexpected findings during hernia surgery, either unusual hernial contents or pathologic entities, like neoplastic masses, masquerading as a hernia. PATIENTS AND METHODS: We studied retrospectively 856 patients with inguinal hernia who were admitted to our surgical department over a 9-year period. In addition, our study included patients complaining of inguinal protrusion, even without a definitive diagnosis of inguinal hernia upon admission. RESULTS: Five patients presented with unusual hernial contents. Three of them had a vermiform appendix in their sac. Acute appendicitis (Amyands hernia) was found in only one case. One patient had epiploic appendagitis related with a groin hernia. Moreover, an adult woman was diagnosed with ovarian and tubal inguinal hernia. Finally, we report a case of a massive extratesticular intrascrotal lipoma, initially misdiagnosed as a scrotal hernia. CONCLUSION: a hernia surgeon may encounter unexpected intraoperative findings. It is important to be prepared to detect them and apply the appropriate treatment.
RESUMO
Afferent loop syndrome is a relatively rare complication after subtotal gastrectomy. We present a late onset of afferent loop obstruction, in a patient who underwent Billroth II gastrectomy with Roux-Y reconstruction for a gastric ulcer 27 years ago. A 60-year-old male was admitted to the hospital with an 8-hour history of acute epigastric pain, associated with vomiting, fever and signs of sepsis. Laboratory tests revealed leukocytosis, elevated liver function tests and high serum amylase. An obstructed afferent loop appeared on CT as a fluid filled tubular mass, crossing the middle line between the aorta and the mesenteric vessels. Advanced sepsis was also seen in the peripancreatic and retroperitoneal region. Although the patient was operated on immediately after diagnosis with reconstruction of Roux-Y anastomosis, he died 12 hours later. Afferent loop syndrome is quite uncommon, and must be suspected in patients who have undergone subtotal gastrectomy. Clinical manifestations of the syndrome are usually non-specific. CT is the examination of choice and surgery the first choice treatment.

Malakoplakia represents a chronic inflammatory disease associated with a broad spectrum of bacterial infections. On histopathology, Michaelis-Gutmann bodies are considered as pathognomonic histopathological findings. Rarity of the disease and wide variety of clinical presentation makes its diagnosis very challenging. We report herein the case of a 66-year-old woman who, having undergone lower anterior resection for rectal adenocarcinoma 3 and a half years ago, presented with urinary frequency and dull abdominal pain. CT scan revealed a soft tissue tumour infiltrating the preperitoneal fat over the urinary bladder, which was considered as recurrence of the rectal carcinoma. On laparotomy, a tumour invading the bladder, small intestine and the anterior abdominal wall was resected and the patient recovered uneventfully. On histopathology, malakoplakia of urinary bladder was revealed. Overstaging of patients' malignancy due to malakoplakia is not uncommon, so its early identification can help avoid incorrect treatment.

BACKGROUND AND AIMS: Variceal bleeding is the most serious complication of portal hypertension associated with high mortality. This study was conducted to investigate any protective effect of early propranolol administration in the development and degree of esophageal varices in cirrhotic rats with portal hypertension. This topic is controversial in the literature. METHODS: For the development of liver cirrhosis and esophageal varices, 60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein, followed by phenobarbital and carbon tetrachloride (CCl(4)) administration. This operation enhances the development of cephalad collaterals, responsible for the induction of esophageal varices. After 2 weeks of CCl(4) administration, the rats were randomly separated into 2 groups. In group I, propranolol was continuously administered intragastrically throughout the study, whereas in group II normal saline (placebo) was administered instead. Cirrhosis was detected clinically by ascites development. Hemodynamic studies and morphometric analysis of the lower esophagus were performed after complete induction of cirrhosis, measuring the following parameters: portal pressure, total number of submucosal veins, total submucosal vessel area, mean cross-sectional submucosal vessel area, relative submucosal area (percentage) occupied by vessels and area of the single most dilated submucosal vein. RESULTS: The statistical analysis revealed no statistically important difference between the 2 groups for the morphometrically studied parameters. However, portal venous pressure was lower in group I. CONCLUSION: Early propranolol administration did not protect rats from developing esophageal varices, despite the fact that a significant decrease in portal pressure was detected.

The Ewing sarcoma family of tumors (ESFT) includes classic Ewing sarcoma of the bone, extraosseous or soft tissue Ewing sarcoma, Askin tumors of the chest wall, and peripheral primitive neuroectodermal tumors of the bone and soft tissues. They share a common neural histogenesis, tumor genetics and biology. The genetic hallmark of the ESFT is the presence of t(11;22)(q24;q12), which creates the EWS/FLI1 fusion gene and results in the expression of a chimeric protein. Although Ewing tumors can occur at any age, the great majority are found in individuals less than 20 years of age. We herein report a case of gastric Ewing sarcoma in a 68-year-old male. This patient illustrates the second reported occurrence of primary Ewing sarcoma in the stomach and the first reported with the t(11;22)(q24;q12) gene translocation.

OBJECTIVE: Emergency surgery for colorectal cancer is common in daily practice, and is mainly implied by bowel obstruction. It is related to increased morbidity and mortality. Its relation with the stage and respectability of the disease is uncertain. This study aims to further clarify these parameters. PATIENTS AND METHODS: Over the past 24-year period 121 patients had an emergency operation (12%) from a total of 1009 patients with colorectal carcinoma. There were 59 men (48.8%) and 62 women (51.2%) with a mean age of 68 years (range 21-93); 61 patients (50.4%) were > or = 70-years-old. The data of all these patients were studied retrospectively in comparison with those who underwent elective surgery. Emergency cases were further divided into two age groups (> or = 70 and < 70 years) and compared. The tumour location was mainly in the left colon, whereas obstruction was the predominant reason for acute presentation. RESULTS: On operation, absence of macroscopic spread was noted in 57.8% of emergency cases and 72% of elective cases (p < 0.05). The resectability rates were 75% and 90% respectively (p < 0.05), and were not significantly affected by the age factor. There were no differences in the grade of malignant cell differentiation or in the depth of microscopic invasion (p > 0.05) in either group. For emergency operations, the morbidity was 20% (24 patients) and the 30-day mortality rate was 5.8% (7 patients). Both parameters were higher in patients > or = 70-years-old. CONCLUSION: Emergency surgery for colorectal carcinoma is related to lower resectability and to higher--but acceptable--postoperative morbidity and mortality rates, when compared with elective surgical management.

BACKGROUND: Wound healing in liver cirrhosis is known to be impaired possibly due to liver insufficiency and subsequent malnutrition status; however, there is no study to examine healing effectiveness of the tooth socket following an extraction in such patients. MATERIALS AND METHODS: Irreversible cirrhosis was induced in 30 Wistar rats by repetitive weekly doses of CCl(4) and continuous administration of phenobarbital in a 12-week course was monitored by body weight measurement and ascites development, and was proved histologically. One week later, cirrhotic and control rats were subjected to extractions of two maxillary grinders on each side, one side by simple method, the other by surgical method. Half of the animals of each subgroup were sacrificed on the 10th post-extraction day, whereas the other half on the 30th post-extraction day, and histological sections were examined from all tooth sockets for wound-healing activity. RESULTS: A malnutrition status was detected in cirrhotic rats with significant difference in their body weight. Several histological parameters of socket healing were not statistically different between cirrhotic and control animals. However, a significant delay on epithelialization and cancellous bone formation was detected on the 10th post-extraction day for either simple or surgical extractions in cirrhotic animals. CONCLUSIONS: Liver cirrhosis in rats provokes a significant delay on epithelialization and mature cancellous bone formation and consecutively on early socket wound healing after a tooth extraction.

Laparoscopic cholecystectomy may lead to serious complications, some of which can be disastrous if they are not recognized and managed immediately. Over the past 12-year period, 1225 laparoscopic cholecystectomies were performed. Totally, major complications occurred in 19 cases (1.5%). The conversion rate was 7.4%. Complications included common bile duct injury in 2 cases (0.16%), vessel injury by trocar or Veress needle in 4 cases (0.32%) including 1 case of aorta injury (0.08%), bleeding from the gallbladder bed or the cystic artery in 10 cases (0.8%), bile leak in 1 case (0.08%), duodenum injury in 1 case (0.08%), and transient liver ischemia in 1 thalassanemic patient (0.08%). The complication was recognized during the operation in 11 cases. Reoperation was necessary in five cases (0.4%), and conservative management was applied in three cases. Although infrequent, major complications may occur during laparoscopic cholecystectomy. Immediate recognition and management is critical and may lead to a safe outcome.

Epidermoid splenic cysts are very rare. Symptoms emerge because of enlargement, infection, haemorrhage or rupture. Although splenectomy is indicated for large cysts, minimally invasive and preservation procedures, such as partial splenectomy or total cystectomy with splenorrhaphy, have been increasingly used during the last decade. We report herein the case of a 16-year old female presented with left upper abdominal quadrant pain, fever and abdominal distention treated in our department.

Traumatic lymphoceles are usually the result of surgical injuries or blunt trauma. Although usually described in the pelvis after radical pelvic node dissection or kidney transplantation, traumatic lymphoceles are rare. Diagnosis is based on CT scan and confirmed by fine needle aspiration with biochemical analysis. Treatment modalities are not standardized and different techniques have been described. We report herein a case of anterior thoracic wall lymphocele due to blunt trauma treated in our department.

OBJECTIVE: Colorectal emergency requiring radical surgery is becoming increasingly frequent in the elderly and problems remain as regards the best management policy. Our long-time experience is presented in this study. PATIENTS AND METHODS: In the last 23 years, 105 elderly patients, aged > or = 65 years, with colorectal disease underwent an emergency operation in our Surgical Department. Forty-five patients (mean age 72 years) had benign disease and 60 patients (mean age 76.5 years) colorectal carcinoma. RESULTS: The carcinoma was located in the left colon (68%), right colon (18%) and rectum (14%). Mostly, patients with malignant cancer presented with obstructive ileus, and patients with benign tumours with perforation and peritonitis, with a predominance of diverticulitis. A resection operation either with primary anastomosis or Hartmann's procedure was performed in 75% of cases; in the rest, only palliation was resorted to. Forty-three percent of the patients with colorectal cancer emergency were > or = 80 years of age. The mean morbidity was 25% and mortality 17%, which make up to 33% and 26.6% for benign disease, and 20% and 10% for malignant cancer, respectively. The mortality rate was higher in patients with perforation than those with obstruction. CONCLUSION: Advanced age is not a contraindication to radical surgery in case of colorectal emergency in the elderly. In the majority, a resection operation is feasible. In high-risk patients, colostomy is a life-saving alternative.

Parastomal hernia represents a common complication of colostomy formation. Surgical techniques such as facial repair and stoma relocation have almost been abandoned because of high recurrence rates. Extraperitoneal prosthetic mesh repair had better results but was accompanied by high rates of mesh contamination. A new technique, with intraperitoneal onlay position of expanded polytetrafluoroethylene (ePTFE) was therefore established. We report herein two cases of symptomatic large parastomal hernias treated in our department.
