ObjectivesThe aim of this study was to evaluate the clinical and radiological results of the surgical treatment of acetabular fractures using modified Stoppa approach.MethodsA total of 57 patients (mean age 37.8 years; range 15–84) who underwent surgical treatment for acetabular fracture with modified Stoppa approach from February 2013 to June 2016 were included into the study. The mean follow-up time was 28.1 months (range 24–35). The records were reviewed for fracture patterns, time to surgery, operative time, blood loss, reduction quality, and perioperative complications. Reduction quality was graded as anatomic, imperfect, or poor. The Harris Hip Score (HHS) and Merle d'Aubigné score were used for functional evaluation.ResultsAmong the 63 acetabulum fractures of the 57 patients, 27 were associated with both columns, 12 were T-type fractures, 10 were transverse, 7 were anterior column/posterior hemitransverse, 5 were anterior column, and 2 were anterior wall fracture. A single surgeon performed all operations. Pfannenstiel incision was used in the first 19 cases while vertical midline incision in the remaining 38 cases. Average time to operation was 5.5 days, and supplemental lateral windows were used in 17 (29.8%) patients. Average blood loss and operation times were 660 mL and 152 min, respectively. Radiological outcomes were anatomic, imperfect, and poor in 52 (82.5%), 9 (14.2%), and 2 (3.2%) of the acetabulum fractures, respectively. Clinical outcomes at 2 years with HHS and Merle d’Aubigné scores were mean 86.6 (range 66–96) (Excellent in 27, good in 23, fair in 4, poor in 3 patient) and 16.7 (range 10–18) (Excellent in 25, very good in 18, good in 6, fair in 5, poor in 3 patient), respectively. There was a significant relation between the reduction quality and clinical outcome (p < 0.001), while there was no significant relation between the clinical outcome and the fracture type (p > 0.05). Iatrogenic external iliac vein damage was noted in 2 patients. Obturator nerve palsy was noted in 3 patients, who recovered spontaneously at mean time of 3.7 months (range 3–5). Rectus abdominus paralysis was noted in 2 of the 19 (10.5%) Pfannenstiel-incision patients but not in the vertical-incision patients.ConclusionOur experience in 57 patients shows that satisfactory results can be obtained, even in bilateral fractures with vertical midline incision.Level of evidenceLevel IV Therapeutic Study

Introduction Metastasis to the gastrointestinal tract from lung cancer is very uncommon and is often asymptomatic. Although small bowel metastasis may commonly occur, metastases to the stomach and colon are uncommon. Case report In this paper, we present a previously healthy 57-year-old male patient, a 60-packet per year smoker, who was taken to the emergency room with complaints of increasing abdominal pain, rectal bleeding, weight loss, and dyspnea for the last three months. Endoscopic examination revealed polypoid lesions in the duodenum and the descending colon. We diagnosed neuroendocrine small-cell lung cancer based on histopathological and immunohistochemical staining. Management and outcome: A cisplatin (d1, 60 mg/m2/day)–etoposide (d1 to d3, 120 mg/m2/day) regimen was given every three weeks as palliative chemotherapy. After the three course of chemotherapy, the lung radiograph showed a decline in hilar expansion and there was no pleural effusion. Then, he died of acute respiratory failure two weeks after radiotherapy of brain. Discussion Gastrointestinal tract metastasis of lung cancer is recognized synchronously with or rarely before diagnosis. It is generally recognized after the diagnosis of lung cancer. These patients often have other concurrent body metastases. Prognosis is poor, and survival expectation is short. The most common metastases to the gastrointestinal tract are squamous and large cell lung cancer metastases. Our aim is to emphasize the importance of immunohistochemical examination for masses in the gastrointestinal tract and to present this rare case of synchronous duodenal and colonic metastases of small-cell lung cancer.

Purpose. The aim of this study is to investigate the reliability of diffusion MRI for detection of cancer foci by comparing diffusion-weighted imaging (DWI) results and pathology results of prostate biopsy sites. Methods. Of the patients who applied with lower urinary tract symptoms, 36 patients who had suspected DRE and/or PSA ≥2.5 ng/mL were included in the study. Patients underwent DWI prior to 10 cores-prostate biopsy. 356 biopsy cores were obtained from the patients. Foci from the patients with prostate cancer were labeled as malignant or benign foci, likewise foci from the patients with benign pathology were grouped as BPH and inflammation foci. Apparent diffusion coefficients (ADCs) of biopsy groups were compared with each other in order to measure the reliability of DWI in detection of PCa foci. Results. When ADC values of adenocarcinoma foci and BPH foci were compared, a statistically significant difference was found (P < 0.001). When ADC values obtained from adenocarcinoma foci and chronic inflammation foci are compared, the difference between two groups is statistically significant, too (P < 0.001). Conclusions. Biopsies focused on suspected regions after formation of ADC maps by means of DWI would provide to start definitive treatment immediately as well as being beneficial to prevent morbidity related to repeated prostate biopsies.

ÖzThis retrospective study aims to reveal the prevalence of sacral dysmorphism, the proportion of its findings and signs and its clinical importance in pelvic surgeries. 1753 nontraumatic pelvic and lower abdominal CT images were analyzed to reveal the sacral abnormal anatomy and dysmorphic signs in nontraumatic patients. Of the patients included in the study; S1-S2 residual disc in 879 (50.60%), the presence of mammillary body or mammillary process in 209 (12%), acute ascending descent in 182 (10.47%), tongue-in-grove sign in 178 (10.25%), deformity in the neural foramen in 168 (9.67%), and collinearity in 121 patients (7%) were detected. The parameters of non-circular amorphous first sacral foramen and lumbosacral disc distance being close to the iliac wing (collinearity) parameters were statistically significantly higher in women than in men (p=0.027; p=0.005). There was no statistically significant correlation between non-circular amorphous first sacral foramen and collinearity parameters and gender (phi=0.149, p=0.027; phi=-0.188, p=0.005). Noncircular amorphous first sacral foramen and residual disc distance between S1 and S2 were found to be statistically significantly higher in the cases (p=0.039). Sacral dysmorphism is an abnormal anatomy that is seen much more common than it is thought in the population and plays an important role in clinical interventions. Keeping this anatomical difference in mind during surgical procedures involving sacrum reduces the possibility of encountering unwanted complications.
