Early and midterm results of the retrograde transpopliteal approach as the first-line treatment for total occlusions of iliofemoral arteries.

OBJECTIVE: This study aims to present our early and midterm results regarding the use of the retrograde popliteal artery approach as the first-line treatment for patients with total occlusions of the iliac or femoropopliteal arteries. PATIENTS AND METHODS: Between July 2017 and July 2019, 84 patients underwent transpopliteal retrograde subintimal recanalization for iliac and femoral artery occlusive disease. RESULTS: The procedure was technically successful in 92.9% of the patients and had a complication rate of 5.95%. Complications, including stent thrombosis, dissection, and rupture, were treated successfully. No hematomas were observed at the puncture site. The primary patency rates at 6, 12, and 18 months were 86.9%, 82.1%, and 77%, respectively. CONCLUSIONS: With respectable early and midterm results, the retrograde popliteal artery approach can be considered a primary treatment option for iliac or femoropopliteal arteries' recanalization in selected patients.

Relationship between nucleotide-binding oligomerization domain-containing protein 2 variants and severity of acute pancreatitis.

BACKGROUND AND AIM: Intestinal barrier dysfunction has been implicated in the development of infectious complications of acute pancreatitis. Nucleotide-Binding Oligomerization DomainContaining Protein 2 (NOD2) plays an important role in the proper functioning of intestinal defense mechanisms. Here, we investigated the frequency of NOD2 variants in patients with mild and severe acute pancreatitis. MATERIALS AND METHODS: Groups 1, 2 and 3 comprised healthy participants and patients with mild and severe pancreatitis, respectively. Four NOD2 variants and serum interleukin-6 (IL-6), Tumor Necrosis Factor-a (TNF-a) and lipopolysaccharide-binding protein (LBP) levels were analyzed. RESULTS: Three patients (3/32, 9.4%) in the severe pancreatitis group were positive for the p.R702W variant. This variant was negative in other groups. One, three and three patients in the healthy (1/27, 3.7%), mild (3/36, 8.3%) and severe pancreatitis (3/32, 9.4%) groups tested positive for the 1007fs variant, respectively. No significant differences in the frequencies of NOD2 variants were evident among the groups. Serum IL-6, TNF-a and LBP levels were markedly higher in the severe pancreatitis than the healthy and mild pancreatitis groups (all p<0.001). We observed no significant correlation between cytokine levels and NOD2 variants. CONCLUSION: Our results support an association between the presence of the p.R702W variant and severe pancreatitis.

Imaging of acute pancreatitis and its complications. Part 1: acute pancreatitis.

Acute pancreatitis is an acute inflammatory disease of the pancreas that may also involve surrounding tissues or remote organs. The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Generally, imaging is recommended to confirm the clinical diagnosis, investigate the etiology, and grade the extend and severity of the acute pancreatitis. Ultrasound is the first-line imaging modality in most centers for the confirmation of the diagnosis of acute pancreatitis and the ruling out of other causes of acute abdomen, but it has limitations in the acute clinical setting. Computed tomography not only establishes the diagnosis of acute pancreatitis, but also enables to stage severity of the disease. Magnetic resonance imaging has earned an ever more important role in the diagnosis of acute pancreatitis. It is especially useful for imaging of patients with iodine allergies, characterizing collections and assessment of an abnormal or disconnected pancreatic duct. The purpose of this review article is to present an overview of the acute pancreatitis, clarify confusing terminology, underline the role of ultrasound, computed tomography and magnetic resonance imaging according to the proper clinical context and compare the advantages and limitations of each modality.

Effects of pleural opening on respiratory function tests in cardiac surgery: a prospective study.

PURPOSE: To show the effects on lung function of the opening pleura in patients undergoing cardiac surgery. SUBJECTS AND METHODS: 66 patients were included. Patients were allocated into two groups. In group 1 (n=21) pleura was intact, in group 2 (n=45) pleura was opened. Both groups were compared prospectively in terms of preoperative and on the post-operative 5th day pulmonary function tests (PFT), preoperative, postoperative first and fifth day arterial blood gas analysis, preoperative and postoperative first day mixt venous oxygen saturation, bleeding, operation periods, pulmonary complications, intensive care and hospital stay period and mortality. RESULTS: There was significant decrease in all PFT indicators on 5th post-operative day in group 2 (p < 0.01). Although there was a significant decrease in FEV1 on 5th post-operative day in group 1 (p < 0.001), other pulmonary functions parameters were not change significantly (p > 0.025). In group 2 much more decline in pulmonary function test parameters than group 1 were observed (p < 0.05). There was not statistically significant difference in blood gas analysis and mixed venous oxygen saturation values in group 1 (p > 0.05). But in group 2 except pH and PaCO2, other blood gas measurements were significantly decreased on the postoperative first and fifth day (p < 0.008). In group 2 except pH and PCO2, other parameters were less than the other Group (p < 0.01). The drained amount was still significantly higher in group 2 (p < 0.001). The frequency of the revision due to bleeding was observed much more in group 2. CONCLUSIONS: Protection of the integrity of pleura may have positive effects on pulmonary functions in cardiac surgery.

Giant post-traumatic cyst after motorcycle injury: a case report with review of the pathogenesis.

Post-traumatic cysts of soft tissue usually occur at the junction of the subcutaneous fat and deep fascia, most often filled with serosanguinous fluid and lined with fibrous tissue. It appears as complication after severe injuries when crushing and shearing forces cause separation of the skin and subcutaneous fat from the deep fascia and muscle, creating a cavity filled with hematoma and liquefied fat. This rare condition calls Morel-Lavallee lesion, which was first described by this French physician in 1853 (Sterling et al., 1977; Tull and Borrelli, 2003). Magnetic resonance imaging is the modality of choice for detection and revealing the exact size and location of these lesions. The best method of treatment is surgical excision with complete resection.

Missed lipoma of the spermatic cord.

The aim of the research was to determine the incidence, significance, and anatomy of spermatic cord and round ligament lipomas. Between 2000 and 2010 we evaluated 969 consecutive patients with 1,070 indirect inguinal hernias, who underwent open repair. A total of 22 lipomas of the spermatic cord or round ligament were identified and resected in 22 patients. No neoplastic changes confirmed in histopathologic examinations of the specimens were reported. Lipomas of the cord and round ligament occur with a considerable incidence. We believe that even if there is no peritoneal sac, the herniation of extraperitoneal fat through the inguinal canal should be counted as an inguinal hernia, and it requires adequate treatment.

Intestinal ischaemia associated with carcinoid tumor: a case report with review of the pathogenesis.

Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that are often indolent and may not become clinically apparent until there is a metastatic spread or evidence of carcinoid syndrome. A 44-year-old man presented to our clinic department with a history of previous left colon cancer operation, chronic crampy left lower quadrant pain, mass and severe anemia. A MR scan was obtained which demonstrated a calcified mesenteric mass 12×8×10 cm diameter with surrounding left colon mesenteric infiltration. The liver was normal. A case of ischaemic ileal necrosis is reported. It was associated with elastic vascular sclerosis produced by mesenteric metastases of an ileal carcinoid tumor. It is postulated that intestinal ischaemia may be of more importance in the production of abdominal pain by carcinoid tumors than has been generally accepted, and that it is the result of functional and structural changes in and around the mesenteric blood vessels, caused by substances secreted by the carcinoid tumor.

Intussusception secondary to a meckel diverticulum in an adolescent.

Adult intussusception caused by an inverted Meckel diverticulum is rare. We report a 39-year-old Turkish man with intussusception due to Meckel diverticulitis. Ileoileal intussusception was suggested by computed tomography. Exploration revealed ileoileal intussusception with Meckel diverticulum. A diverticulectomy with small bowel resection was performed.

Self-gripping Covidien™ ProGrip™ mesh versus polypropylene mesh in open inguinal hernia repair: multicenter short term results.

The purpose of this study was to compare clinical outcomes following sutureless ProGrip™ mesh repair to traditional Lichtenstein repair with polypropylene mesh secured with sutures. Data were collected prospectively and were analyzed for 57 male and 3 female patients with 60 inguinal hernias. All patients included underwent open surgical repair for inguinal hernia with polypropylene mesh or ProGrip mesh. In our two centres study sixty patients were operated; 30 were treated with Lichtenstein repair with polypropylene mesh (L group) and 30 with ProGrip mesh (P group) with or without fixation. The primary parameter measured was intensity of postoperative pain using visual analogue scale (VAS); other outcomes included assessment of early and late complication. VAS was assessed in 7 days and 4 months of the postoperative period. Our results show that VAS scored at the 7th postoperative day was 1.5 for the ProGrip mesh versus 4.4 in Lichtenstein repair group. The difference between groups was statistically significant (P=0.001). Surgery duration was significantly shorter in the P group (24.9 vs. 58.3 min; P=0.001). No recurrence was observed at 3 months in both groups. The 3-months follow-up has shown that time necessary to return to daily routine activity was significantly lower in the P group during the (P=0.001). Surgery duration, early and late postoperative, pain and return to daily routine activity rates were significantly reduced with self-gripping ProGrip mesh compared to Lichtenstein repair with polypropylene mesh.

Long-term quality of life after hernioplasty using a Prolene hernia system in adult inguinal hernia.

INTRODUCTION: Most surgeons favour the use of a mesh for open inguinal hernia repair as it has a low recurrence rate. Procedures used most frequently are the Lichtenstein method, mesh plug repair and the Prolene hernia system (PHS). The choice of technique may be influenced by effects on postoperative pain and quality of life. In this retrospective study, results from inguinal hernia repair with the PHS in a regional training hospital were analysed. PATIENTS AND METHODS: Thirty primary inguinal hernias were treated with PHS. The primary endpoint was the recurrence rate. Secondary endpoints were short-term and long-term complications. Pain was evaluated by use of a visual analog scale (VAS, 0-100), and a short-form 36-item questionnaire was used to assess postoperation quality of life. All patients visited the outpatient clinic for a physical examination (100% follow up). RESULTS: After a median follow up of 8 years, one patient was diagnosed with recurrent herniation (3.3%). Three self-limited wound discharge (10%), and one haematoma needing surgical evacuation (3.3%) were diagnosed. Two patients (6.6%) suffered from persistent pain (VAS > 40). Average VAS score was 21 (0-80) 8 years after surgery. CONCLUSION: In a regional training hospital, primary inguinal hernias were treated with low recurrence and few complications by use of the PHS.

Persistence of 99mTc-labelled microorganisms on surfaces of impression materials.

Impression materials or prostheses can be contaminated with oral microflora and provide a significant source for cross-contamination. A study of such contamination was carried out using an approach different from that of infection control, which has often been investigated in previous studies. The study focused on microorganisms known to cause local and systemic diseases and which are normally found in the oral flora. The persistence of Streptococcus mutans (S. mutans), Escherichia coli (E. coli), Staphylococcus aureus and Candida albicans (C. albicans) on zinc-oxide eugenol, silicone rubber, irreversible hydrocolloid and polyether-rubber was investigated using 99mTc-labelled microorganisms. Ten specimens from each of the four impression materials were prepared as discs of 3 mm in height and 10 mm in diameter. After the specimens had been placed into a suspension of 99mTc-labelled microorganisms, remaining radioactivity was counted in a gamma counter. According to own findings, S. mutans was the most, and E. coli the least persistent on the specimen surfaces. The number of microorganisms removed after washing was less than the amount remaining on the surfaces. C. albicans was removed most easily from all impression surfaces that bore persistent microorganisms after washing. Other microorganisms showed various degrees of persistence according to the impression material.
