An inflammatory myofibroblastic tumor of the ampulla of Vater, an exceptional location: a case report.

Introduction And Importance: Inflammatory myofibroblastic tumors constitute a group of mesenchymal tumors associated with inflammatory infiltration. They occur mainly in young patients. It is classified by the World Health Organization as a borderline neoplasm.

Dermatofibrosarcoma protuberans of the anterior abdominal wall: case report and literature review.

Dermatofibrosarcoma protuberans (DFSP) is a rare and slowly growing cutaneous tumor with high risk of local invasion and recurrence. Here, we report a case of a DFSP of the anterior abdominal wall diagnosed in a 45-year-old woman. The clinical examination showed an indurated well-limited oval mass localized in the supra-umbilical level and measuring 5 cm by 3 cm.

Impact of mental imagery on enhancing surgical skills learning in novice's surgeons: a pilot study.

Objective: Mental imagery (MI) has long been used in learning in both fields of sports and arts. However, it is restrictively applied in surgical training according to the medical literature. Few studies have evaluated its' feasibility and usefulness.

Reproduction of the Cancer Genome Atlas (TCGA) and Asian Cancer Research Group (ACRG) Gastric Cancer Molecular Classifications and Their Association with Clinicopathological Characteristics and Overall Survival in Moroccan Patients.

Introduction: The Cancer Genome Atlas (TCGA) project and Asian Cancer Research Group (ACRG) recently categorized gastric cancer into molecular subtypes. Nevertheless, these classification systems require high cost and sophisticated molecular technologies, preventing their widespread use in the clinic. This study is aimed to generating molecular subtypes of gastric cancer using techniques available in routine diagnostic practice in a series of Moroccan gastric cancer patients.

Microsatellite Instability Analysis in Gastric Carcinomas of Moroccan Patients.

To investigate correlations between microsatellite instability (MSI) and the phenotype, clinicopathological features, and overall survival (OS) in Moroccan gastric cancer (GC) patients. We evaluated the mutation frequency of 22 MSI-target genes in MSI-positive tumors. MSI evaluation were performed for 97 gastric tumors by multiplex polymerase chain reaction (PCR) using a panel of five quasimonomorphic mononucleotide repeat markers (NR27, NR21, NR24, BAT25, and BAT26).

Acute cecal volvulus: A diagnostic and therapeutic challenge in emergency: A case report.

Introduction: Cecal volvulus is an uncommon cause of intestinal obstruction due to an axial twist of the caecum, ascending colon and terminal ileum around the mesenteric pedicle. It is responsible for 1%-1.5 of all intestinal obstructions in adult.

[Total small bowel volvulus complicating common incomplete mesentery, an exceptional complication in adults: about a case].

Total small bowel volvulus complicating common incomplete mesentery is an arrest of rotation of the primary intestinal loop at 180°. The root of the mesentery is very short and the whole small intestine is located on the superior mesenteric artery axis. Patients are at very high risk of small bowel volvulus and enteromesenteric infarction.

[Pseudocontinent perineal colostomy: an exceptional complication].

Stoma prolapse is an exceptional and late complication of pseudocontinent perineal colostomy. Very rare cases have been described in the literature. We here report the case of a 75 year old patient with no particular past medical history as well as our therapeutic approach.

Fournier gangrene: rare complication of rectal cancer.

Fournier's Gangrene is a rare complication of rectal cancer. Its discovery is often delayed. It's incidence is about 0.

Stromal tumor of the lesser omentum : a case report.

Gastrointestinal stromal tumors (GISTs) represent the majority of primary non-epithelial neoplasms of the digestive tract, most frequently expressing the KIT protein detected by immunohistochemical staining for the CD117 antigen. Extragastrointestinal stromal tumors (EGISTs), neoplasms with immunohistological features overlapping those of GISTs, are found in the abdomen outside of the gastrointestinal tract with no connection to the gastric or intestinal wall. We report the clinical, macroscopic and immunohistological features of an EGIST arising in the lesser omentum of a 58-year-old woman.

Nonlinear Cascade Strategy for Longitudinal Control of Electric Vehicle.

The problem of controlling the longitudinal motion of front-wheels electric vehicle (EV) is considered making the focus on the case where a single dc motor is used for both front wheels. Chassis dynamics are modelled applying relevant fundamental laws taking into account the aerodynamic effects and the road slope variation. The longitudinal slip, resulting from tire deformation, is captured through Kiencke's model.

Traumatic appendicitis: a case report and literature review.

Appendicitis and trauma may exist together, which causes an interesting debate whether trauma has led to appendicitis. We report a case of appendicitis after an abdominal trauma. Our patient developed acute appendicitis following a stab wound in the right iliac fossa.

Recurrent desmoid tumor of the abdominal wall.

Desmoid tumors most often occur in abdominal wall. Their tendency to recur lead to repeated operations which can make the abdominal wall reconstruction difficult. We report a 28-year-old female history.

[Resectability evaluation in pancreatic cancer].

Accurate staging of pancreatic cancer is essential in order to select patients, which are candidates for curative resection. Multidetector computed tomography is the best imaging for determination of pancreatic cancer loco regional and distal resectability. Endoscopic ultra sonography has complementary role in small tumours.

Appendiceal intussusception to the cecum caused by mucocele of the appendix: Laparoscopic approach.

Introduction: Appendiceal intussusception is a very rare disease that is found in only 0.01% of patients who have undergone an appendectomy. Clinical symptoms vary and some patients are asymptomatic.

Colonic adenocarcinoma revealing Crohn's disease: a case report.

Introduction: There is growing evidence from epidemiological studies and clinicopathological data obtained from case reports that Crohn's disease is associated with an increased risk of carcinoma of the large bowel.

Case Presentation: A 70-year-old Arabic African man with undiagnosed Crohn's disease presented with acute abdominal obstruction due to an occlusive carcinoma of the sigmoid. At laparotomy, the colonic tumor was excised with continuity restored by end-to-end anastomosis.

Uncommon mimics of appendicitis: giant mucocele.

Appendiceal mucocele is an infrequent but well recognized entity that can present with a variety of clinical syndromes or can be asymptomatic and discovered incidentally. A 55 years old patient was admitted in the emergency department for acute right lower quadrant pain. A diagnosis of appendicitis was made.

Simultaneous acute appendicitis and ectopic pregnancy.

The acute abdomen in pregnancy is a surgical emergency. Ectopic pregnancy and appendicitis are two causes of acute abdomen in pregnancy. Difficulties in correctly identifying the cause of the pain can be hazardous to the patient and care needs to be taken in obtaining a prompt and accurate diagnosis enabling the most appropriate management.

[Surgically treated chronic aortic insufficiency: prognostic value of preoperative echocardiography].

Between March 1979 and December 1998, 38 patients with isolated chronic aortic insufficiency underwent aortic valve replacement. The aim of this study is to determine whether preoperative echocardiography parameters are useful in predicting operative results in patients with aortic valve replacement for chronic aortic insufficiency. The global survival is 92% in one year and 89% in ten years.
