RESUMO

BACKGROUND: Access-related injuries are still an important consideration and may increase morbidity and mortality. This study aimed to present in detail a safe and easy technique for open insertion of the first trocar. PATIENTS AND METHODS: This technique has been used routinely in the vast majority of laparoscopic procedures at first author's department since 1998. The data were collected prospectively and analyzed retrospectively for the 11-year period of January 2005 through December 2015. The primary site of access is the umbilicus, but this technique can be used for all insertion points. RESULTS: A total of 2579 laparoscopic surgical interventions were performed. The abdominal access was established in 2252 patients in open and in 321 cases with blind puncture using a Veress needle. There were three cases (0.9 %) of accidental injuries with blind puncture and two cases (0.09 %) with open technique. Injuries sustained with open technique injuries were less severe and immediately discernable. None of the patients were converted to open technique. CONCLUSION: The method can be used easily and rapidly, even in obese patients. It is safer than blind puncture and reduces costs.

RESUMO

The term bezoar refers to an intraluminal mass in the gastrointestinal system caused by the accumulation of indigestible ingested materials, such as vegetables, fruits, and hair. Bezoars are responsible for 0.4%-4% of cases of mechanical intestinal obstruction. The clinical findings of bezoar-induced ileus do not differ from those of mechanical intestinal obstruction due to other causes. The appearance and localization of bezoars can be established with various imaging methods. Treatment of choice depends on the localization of the bezoar which makes the clinical findings.

RESUMO

Diaphragmatic injuries either by blunt or penetrating trauma require prompt surgical intervention and are often exigent to repair. N-butyl-2-cyanoacrylate (n-butyl-2-CA) is a tissue adhesive which has gained wide application in many areas of surgery including emergency. To repair the extensive injuries of the diaphragm it may be necessary the use of synthetic mesh by fixing it with sutures or staples. The use of tissue adhesives may circumvent the potential problems associated with mesh fixation. This study aimed to evaluate the efficacy and safety of tissue adhesives usage for mesh fixation in diaphragmatic injury repair. Twenty-four rats were divided into 3 groups each of them containing 8 rats. A 1- cm diaphragmatic defect was created in all rats. The defect was repaired by polypropylene suture in Group I, by mesh fixed with sutures in group II and by mesh fixed with n-butyl-2-CA in group III. The rats were sacrificed after 1 month. The episode of hernia and the adhesions were assessed by adhesion density score. Also, the abscess and inflammation in the repaired tissue were evaluated microscopically. The Kruskal-Wallis test was performed for the histopathological analysis. No diaphragmatic hernia was detected in any group. While Group III had higher adhesion density scores than group I (P: 0.027), there were no differences between group III and II (P: 0.317) and group II and I (P = 0.095) regarding adhesion density scores. The inflammation grade was higher in group III than group I and II (P < 0.001) and was higher in group II than group I (P < 0.05). There was no differences between each groups, concerning microabcsess formation (P > 0.05). Repair of traumatic diaphragmatic injury in penetrating wound, with polypropylene mesh fixed by n-butyl-2-CA in rats appears to be as efficacious and safe as conventional methods in early period. However, further experimental and clinical study are needed to compare the long-term results of adhesive mesh repair with those of the traditional sutured techniques.

RESUMO

Intrahepatic cholestasis of pregnancy (ICP) is a reversible pregnancy-specific cholestatic condition characterized by pruritus, elevated liver enzymes, and increased serum bile acids. It commences usually in the late second or third trimester, and quickly resolves after delivery. The incidence is higher in South American and Scandinavian countries (9.2%-15.6% and 1.5%, respectively) than in Europe (0.1%-0.2%). The etiology is multifactorial where genetic, endocrine, and environmental factors interact. Maternal outcome is usually benign, whereas fetal complications such as preterm labor, meconium staining, fetal distress, and sudden intrauterine fetal demise not infrequently lead to considerable perinatal morbidity and mortality. Ursodeoxycholic acid is shown to be the most efficient therapeutic agent with proven safety and efficacy. Management of ICP consists of careful monitoring of maternal hepatic function tests and serum bile acid levels in addition to the assessment of fetal well-being and timely delivery after completion of fetal pulmonary maturity. This review focuses on the current concepts about ICP based on recent literature data and presents an update regarding the diagnosis and management of this challenging issue.

RESUMO

Most ingested foreign bodies usually pass out in the feces uneventfully. Complications such as intestinal perforation and bleeding usually occur with sharp, thin, stiff, long, and pointed objects. This case describes the management of three lead pellets within the appendix vermiformis. A 45-year-old male visited our clinic complaining of a 4-month history of abdominal pain. The patient inquiry revealed that he had eaten hunted rabbit meat on numerous occasions and had unintentionally ingested three lead pellets. Plain abdominal films and a barium enema showed foreign bodies in the right lower abdominal quadrant. Since the lead pellets were thought to have migrated extraluminally, they were removed through laparotomy under fluoroscopic guidance. An appendectomy was performed. Pathologically, three lead pellets were embedded in the appendix, which showed signs of intramucosal inflammation. Foreign bodies causing appendicitis are rare. However, if stiff or pointed objects enter the appendicular lumen, there is a high risk of appendicitis, perforation, or abdominal pain. An appendectomy was required to remove the ingested lead pellets in the appendix.

RESUMO

BACKGROUND: Bile duct injury (BDI) as a complication of laparoscopic cholecystectomy may result in biliary cirrhosis with a high morbidity-mortality rate. Recurrent invasive procedures may be required for the optimum management. The most frequent causative factor in BDI is anatomical misidentification, particularly by inexperienced surgeons. Direct coloration of the cystic duct, bile duct, and gallbladder may decrease biliary tract injury. METHODS: This study was conducted during 10 standard, fresh cadaver autopsies at the Council of Forensic Medicine, Istanbul. Following needle puncture of the gallbladder fundus and aspiration of the bile content, identical quantities of isosulphan blue were injected into the gallbladder to visualize the biliary tract. RESULTS: Of the ten fresh cadavers, three were males and seven were females; the mean age at death was 43 years (range 22-76 years). Successful visualization of the colored biliary tract, encompassing the gallbladder, cystic duct, and bile duct, was achieved in all of the cadavers. CONCLUSIONS: Visualization of the biliary tract may reduce the risk associated with dissection of Calot's triangle. Surgical BDI risk following anatomical misidentification could be reduced by intraoperative injection of isosulphan blue; further studies are required to validate the clinical utility of this technique.

RESUMO

BACKGROUND/AIM: In the present study, the protective effect of erdosteine against cyclosporine-induced injury in rat liver was investigated with histological and biochemical methods. MATERIALS AND METHODS: Thirty-two Wistar albino male rats were randomly divided into 4 groups: control (n = 8), cyclosporine (n = 8, 20 mg kg(-1) day(-1) i.p.), cyclosporine + erdosteine (n = 8, erdosteine 12 mg kg(-1) day(-1) orally), and erdosteine (n = 8). At the end of day 12, liver tissues were removed for histological and biochemical analysis. After liver tissues were fixed in 10% buffered neutral formalin, routine histological processes were applied and tissue sections were stained with hematoxylin and eosin, periodic acid-Schiff, and elastic fiber stain methods. One hundred lobules of liver were examined for each group and evaluated statistically. The levels of malondialdehyde and glutathione peroxidase, as well as the activities of superoxide dismutase, were determined. RESULTS: The cyclosporine group showed significant histopathological changes compared to the control. In the cyclosporine + erdosteine group, histopathological changes of hepatic damage were markedly reduced. Histological findings were supported by biochemical results. CONCLUSION: Erdosteine could attenuate cyclosporine-induced liver injury.

RESUMO

We aimed to analyze the diagnostic value of mean platelet volume and platelet distribution width, which are also known as the markers of platelet count, in acute and perforated appendicitis. The data of 202 patients who applied to general surgery clinic in Mustafa Kemal University Hospital from 2007 to 2012 with acute appendicitis were analyzed retrospectively. The findings were separated to two groups due to the perforation status (perforated vs. non-perforated). Age, sex, leukocyte, hemoglobin, hematocrit, mean platelet volume, and platelet distribution width were examined. The mean age of the patients was 35.8. Twenty-one of all cases were perforated appendicitis (10.4 %), and the rest was acute appendicitis (non-perforated) (n = 181, 89.6 %). The mean platelet volume value was 9.8 ± 2.1 fL; mean thrombocyte count, 340.9 × 10(9)/L; and mean platelet distribution width value, 18.3 %. There were statistically significant differences between sex and age, hemoglobin, hematocrit, leukocyte, mean platelet volume, and platelet distribution width. There was a positive correlation between mean platelet volume, platelet distribution width, and platelet. Age, leukocyte, platelet, mean platelet volume, and platelet distribution width were higher in cases with perforation as a comparison with non-perforated cases. We think that mean platelet volume and platelet distribution width may be valuable markers to detect the risk of perforation in early periods of acute appendicitis.

RESUMO

Idiopathic granulomatous mastitis is a rare chronic inflammatory lesion of the breast that can clinically and radiographically mimic breast carcinoma. The most common clinical presentation is an unilateral, discrete breast mass, nipple retraction and even a sinus formation often associated with an inflammation of the overlying skin. The etiology of idiopathic granulomatous mastitis is still obscure. Its treatment remains controversial. The cause may be the autoimmune process, infection, a chemical reaction associated with oral contraceptive pills, or even lactation. Various factors, including hormonal imbalance, autoimmunity, unknown microbiological agents, smoking and α 1-antitrypsin deficiency have been suggested to play a role in disease aetiology. In this review, causing factors in the aetiology of idiopathic granulomatous mastitis are reviewed in detail.

RESUMO

INTRODUCTION: Gastric volvulus is a rare surgical emergency with a high mortality rate that requires urgent surgical management. PRESENTATION OF CASE: A 19-year-old male and 51-year-old female patient underwent emergency surgery with a prediagnosis of acute abdomen syndrome, and a 60-year-old female patient underwent elective surgery due to diaphragmatic hernia. Abdominal exploration revealed gastric volvulus together with perforation in received emergency surgery patients, and a mesenteroaxial gastric volvulus due to diaphragmatic defect in third patient. DISCUSSION: Gastric volvulus is classified into four subgroups depending on the mechanism of development, and organoaxial form is the most common type of gastric volvulus. The most challenging step in diagnosing gastric volvulus is the consideration of this diagnosis. CONCLUSION: Preoperative diagnosis is often difficult, and its management involves surgical correction of the pathology followed by institution of resuscitative treatment.

RESUMO

Squamous cell carcinoma (SCC) is a rare complication observed mainly in chronic, recurrent and untreated primary pilonidal disease. It is associated with poor prognosis, and its recurrence rate after surgery is high. Here we present a patient diagnosed with SCC arising from a neglected pilonidal sinus. A 44-year-old male, who is a heavy truck driver, applied to the hospital with chronic discharge from sacrococcygeal region. He had symptoms of the disease with multiple recurrent abscesses and spontaneous drainage for 10 years. The patient underwent cyst excision and the defect was left open for secondary healing. One year later, the patient was admitted to the hospital with a mass of 3 x 3 cm in the same area. Re-excision and a sigmoid colostomy were performed. The patient died after two years. This case study illustrates that since SCC is a fatal complication of recurrent and long-standing pilonidal sinus, the proper treatment of this disease should be carried out as soon as the diagnosis is established. To this end, we believe, that all pilonidal sinus lesions should be sent for pathologic examination.

RESUMO

INTRODUCTION: A strangulated inguinal hernia is a common indication for emergency surgery. In comparison, complete testicular feminization is a rare genetic disease that can present with an inguinal hernia because of ectopically positioned testicles. PRESENTATION OF CASE: A 70-year-old female was admitted to the emergency service complaining of a painful swelling in the right inguinal region for 1 day. The physical examination indicated a strangulated inguinal hernia and surgery was performed. On exploring the inguinal region, a strangulated indirect inguinal hernia and hard 2×3-cm mass were detected. The histopathological examination of the excised mass showed testicular tissue, and complete testicular feminization (CTF) was diagnosed after further examinations. DISCUSSION: Androgen insensitivity syndrome (AIS), the most frequent cause of male pseudohermaphroditism. The diagnosis of patients with AIS is usually made at the beginning of the second decade when a healthy person with a female phenotype complains of no menarche. Making a first diagnosis after the 5th decade is extremely rare. CONCLUSION: While AIS can be diagnosed in early adulthood, cases might not bediagnosed until the patient is of advanced age.

RESUMO

INTRODUCTION: We investigated prognostic parameters of patients who underwent surgical intervention for acute mesenteric ischemia by evaluating demographic characteristics and laboratory data on admission. METHODS: The hospital records of 30 patients who underwent surgical interventions due to acute mesenteric ischemia between January 2008 and December 2012, were reviewed retrospectively. The records were investigated with regard to demographic data, the presence of co-morbid diseases, presenting complaints, time elapsed between symptom onset and hospital admission, laboratory findings at admission, findings at surgical exploration, surgical methods used, and treatment outcomes. The patients were divided into two groups, according to death (Group 1) or survival (Group 2), and the two groups were compared in terms of the specified parameters. RESULTS: Of the patients, 15 were male (50%) and 15 female (50%); their mean age was 71.4 (29-94) years. Abdominal pain was the chief complaint in all patients (100%) and mean time from pain onset to hospital admission was 21 (1-72) h. In abdominal exploration, total small bowel (SB) ischemia and necrosis was found in 6 (20%) patients and other patients had subtotal SB, segmental SB, segmental SB with colon, or isolated colon ischemia. Treatment in 15 patients (50%) ended in mortality. Mean age (p = 0.038), urea (p = 0.002), AST (p < 0.001), ALT (p < 0.001), mean platelet volume (MPV; p = 0.002), and amylase (p = 0.022) levels in Group 1 were significantly higher versus Group 2, whereas Ca (p = 0.024) and albumin (p = 0.002) levels were significantly lower. CONCLUSIONS: In this study, unlike other parameters that have been shown to be of prognostic significance in mesenteric ischemia, MPV values at presentation were higher among non-survivors than survivors.

RESUMO

Introduction. Gossypiboma (GP) is a term used to express the mass resulting from forgotten cotton sponge in operations. Rarely, a transmural migration may occur into the gastrointestinal lumen without creating any defect by GP. Laparotomy or endoscopic removal may be required, by the way it can be taken out of the body itself by intestinal ways. In this study, we reported a case of mechanical intestinal obstruction causing GP. Case. The fifty-one-year-old female patient admitted to the emergency department with the complaints of mechanical intestinal obstruction and had a history of open cholecystectomy 20 years ago. There were the findings of intestinal obstruction in abdominal plain radiography and computerized tomography. The sponge that obstructed the lumen completely 40 cm proximal to the ileocecal valve was identified in the laparotomy with the diagnosis of brid ileus. The small intestine was closed over double-fold after removal of sponge. Transmural migration of abdominal-remained sponge was thought to be occurred without creating a defect after cholecystectomy. Postoperatively, the patient was discharged without having any problems at 4th day of hospitalization. Conclusion. Although it is a rare situation in routine clinical practice, GP should be considered as a differential diagnosis in the patients who had a diagnosis of mechanical intestinal obstruction, and laparotomy was applied before. As GP may lead to situations which cause mortality, all precautions should be taken to prevent it.

RESUMO

AIM: The aim of this study was to determine the effects of letrozole (LTZ), an aromatase inhibitor (AI), and melatonin (MLT) on hepatic function and oxidative stress in female rats. MATERIAL AND METHODS: A total of 32 female rats were divided equally into four groups (n = 8). Control group received saline (0.5 ml/day, oral gavage). LTZ was administered to rats by daily oral gavage at 1 mg/kg dose. LTZ + MLT group was given LTZ (1 mg/kg, oral gavage) plus MLT (0.5 mg/kg/day, s.c.). MLT group was given MLT (0.5 mg/kg/day) by s.c. injection. The activities of superoxide dismutase (SOD) and catalase (CAT) and malondialdehyde (MDA) levels were measured in liver tissue. Total antioxidant capacity (TAC), total oxidant status (TOS), ALT, AST, GGT, ALP, LDH, bilirubin, BUN, creatinine, total cholesterol (TC), high-density lipoprotein (HDL) and triglyceride (TG) were assayed in serum samples. RESULTS: The oxidative stress parameters did not differ between groups. LTZ administration increased hepatic function parameters such as AST, LDH, ALP, bilirubin and MLT improved the disturbances of hepatic function. LTZ caused minimal histological changes in liver tissue and MLT treatment reversed those dejenerations. DISCUSSION: LTZ may cause hepatotoxicity without inducing oxidative stress and MLT restores hepatic activity.

RESUMO

BACKGROUND: NSAIDs have been found to induce gastrointestinal tract damage. Recently, it has been suggested that this might be mediated by lipid peroxidation. OBJECTIVE: The aim of this study was to assess the potential protective effects of ß-glucan against acetylsalicylic acid (ASA-induced gastric damage by means of its antioxidant capacity in an experimental rat model. METHODS: Thirty-two male Wistar albino rats (200-250 g) were randomized into 4 groups consisting of 8 rats each. The ß-glucan group received 50 mg/kg ß-glucan once a day for 10 days and 30 minutes before anesthesia. The ASA group received saline once a day for 10 days and 300 mg/kg (20 mg/mL) ASA as a single dose, 4 hours before anesthesia. The ASA+ß-glucan group was administered 50 mg/kg ß-glucan once a day for 10 days and 30 minutes before anesthesia. Additionally, 300 mg/kg (20 mg/mL) ASA was administered as a single dose, 4 hours before anesthesia. The control group received saline once a day for 10 days and 30 minutes before anesthesia. All medications were administered by intragastric gavage. The stomach from each rat was dissected and divided into 2 parts for histologic and biochemical analysis. Gastric tissue malondialdehyde (MDA), nitric oxide (NO) levels, catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities were determined for oxidative parameter analysis. RESULTS: The gastroprotective and antioxidant effects of ß-glucan appeared to attenuate the ASA-induced gastric tissue damage. Compared with the control group, MDA and NO levels and CAT and GSH-Px activities were significantly increased in the stomachs of ASA-treated rats (MDA, 4.12 [0.44] to 13.41 [1.05] µmol/L; NO, 8.04 [7.25-9.10] vs 30.35 [22.34-37.95] µmol/g protein; CAT, 0.050 [0.004] to 0.083 [0.003] k/g protein; GSH-Px, 0.57 [0.42-0.66] to 1.55 [1.19-1.76] U/L; all, P < 0.001), whereas SOD activity was significantly decreased in the same group (291 [29] to 124 [6] U/mL; P < 0.001). In the ASA+ß-glucan group, MDA and NO levels and CAT and GSH-Px activities were found to be significantly lower, while SOD activity was found to be significantly higher, in comparison with the ASA-treated group (all, P < 0.001). CONCLUSION: ß-Glucan appeared to attenuate the gastric damage caused by ASA in these rats.

RESUMO

Early diagnosis of diaphragmatic rupture after traumas may be difficult, and delayed diagnosis may result in increased morbidity and mortality. This paper describes the case of a 32-year-old man who experienced a traffic accident and had diagnosis of traumatic diaphragmatic hernia nearly four months later. The patient was referred to our emergency room suffering from ileus symptoms. Physical examination demonstrated an apparent abdominal distention, tenderness at the upper abdominal quadrants, rebound, and defense. Thoraco-abdominal X-rays and computerized tomography imaging demonstrated intestinal segments with air-fluid levels in thorax. Laparotomy was performed after a preoperative diagnosis of a strangulated-diaphragmatic hernia. At abdominal exploration, it was found that transverse colon and omentum entered into thorax through diaphragmatic defect located at the left diaphragm. Herniating colon segment was complicated with ischemic necrosis and perforation. In conclusion, colon necrosis and perforation may develop when early diagnosis of diaphragmatic ruptures are missed.

RESUMO

INTRODUCTION: Cyclosporine A, an immunosuppressive agent, is widely used after organ transplantation such as the liver and kidney. However, its widespread use is restricted because it has serious toxic effects on the kidney. Caffeic acid phenethyl ester (CAPE) is a natural product with potent anti-inflammatory, antitumor, and antioxidant activities, and it attenuates inflammation and lipid peroxidation induced by ischemia-reperfusion injury. The purpose of the present study was to investigate the effects of CAPE on cyclosporine A (CsA)-induced nephrotoxicity. MATERIAL AND METHODS: Rats were divided into four groups and treated with saline, CAPE, CsA, and CsA + CAPE. Control rats were given saline; the CAPE group was given CAPE (10 micromol/kg/day) for 11 days intraperitoneally; the CsA group was given CsA (15 mg/kg/day) for 10 days subcutaneously; and the CsA+CAPE group was given CAPE for 11 days, and rats were s.c. injected with CsA in 0.5 ml of saline once a day for 10 days at the same time. RESULTS: The administration of CsA alone resulted in higher myeloperoxidase (MPO) activity, lipid peroxidation, superoxide dismutase (SOD), and catalase (CAT) than in the control. The enzyme activities except CAT in rats treated with CAPE alone were not changed. CAPE treatment prevented the increase in malondialdehyde (MDA) and increased CAT activity more, but did not affect the activities of MPO and SOD enzymes. DISCUSSION: CsA causes renal injury and CAPE prevents CAT- and lipid peroxidation-mediated nephrotoxicity via inhibition of oxidative process.
