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. The case presented here underlies the pathogenesis of the simultaneous existence of these two conditions in a patient.

Abstract Intussusceptions in adults is rare. Gastrointestinal lipomas are rare benign tumors and intussusceptions due to a gastrointestinal lipoma constitutes an infrequent clinical entity. Lipoma may develop as a benign tumor in all organs and rarely in large or small intestine. The present report describes a case of jejunojejunal intussusceptions in an adult with a history of colicky upper abdominal pain. Ileo-ileal invagination was diagnosed by computed tomography scan. Exploratory laparotomy revealed jejunojejunal intussusceptions secondary to a lipoma which was successfully treated with segmental intestinal resection. A review of the literature is also performed regarding this rare association revealing the diagnostic and therapeutic debates that exist. Abstract (french) L’invagination chez les adultes est rare. Les lipomes gastro-intestinaux sont de rares tumeurs bénignes et l’invagination intestinale due à un lipome gastro-intestinal constitue une entité clinique trés rare. Le lipome peut se développer comme une tumeur bénigne dans tous les organes et rarement dans l’intestin grêle ou le colon. Le présent rapport décrit un cas d’invagination jéjunojéjunale chez un adulte avec une histoire de douleurs abdominales. Iléo-iléale invagination a été diagnostiquée par tomodensitométrie. Une laparotomie exploratrice a révélé l’existence d’une invagination jéjunojéjunale secondaire à un lipome qui a été traitée avec succès par une résection intestinale segmentaire. Une revue de la littérature est également effectuée au sujet de cette association rare révélant les débats diagnostiques et thérapeutiques qui existent.

Abstract Introduction Gastrointestinal stromal tumors are a rare neoplasm exhibiting, in most cases, mutations of c-kit. Imatinib mesylate is the standard treatment for patients who have advanced gastrointestinal stromal tumors. Although the response rate in patients treated with imatinib mesylate in prospective clinical studies is above 50%, a complete response is very rare. We report the case of a patient with a gastric gastrointestinal stromal tumor who had a pathological complete response after neoadjuvant treatment with imatinib mesylate. Case presentation We report the case of a 54-year-old Arab woman with a gastrointestinal stromal tumor who had a pathological complete response after neoadjuvant treatment with imatinib mesylate. Conclusion The pathological examination of our patient documented a complete pathological response after imatinib therapy. Recently, it has been confirmed that the kinase genotype of KIT and platelet-derived growth factor receptor α can accurately predict a good response to imatinib mesylate therapy. We propose that this patient had a mutation conferring high sensitivity to imatinib mesylate.

Background: Tumors with microsatellite instability (MSI tumors) have distinct clinicopathological features. However, the relation between these tumor subtypes and survival in colon cancer remains controversial. The aim of this study was to evaluate the overall survival (OS) in patients with MSI phenotype, in FES population., Methods: The expression of MMR proteins was evaluated by immunohistochemistry for 330 patients. BRAF , KRAS , and NRAS mutations were examined by Sanger sequencing and pyrosequencing methods. The association of MSI status with a patient's survival was assessed by the Kaplan-Meier method and log-rank test., Results: The mean age was 54.6 years (range of 19-90 years). The MSI status was found in 11.2% of our population. MSI tumors were significantly associated with male gender, younger patients, stage I-II, right localization, and a lower rate of lymph node and distant metastasis. The OS tends to be longer in MSI tumors than MSS tumors (109.71 versus 74.08), with a difference close to significance ( P = 0.05)., Conclusion: Our study demonstrates that MSI tumors have a particular clinicopathological features. The results of survival analysis indicate that the MSI status was not predictive of improved overall survival in our context with a lower statistical significance ( P = 0.05) after multivariate analysis., Competing Interests: The authors report no conflicts of interest., (Copyright © 2019 Fatima El Agy et al.)

Background: Intussusception is a relatively common cause of intestinal obstruction in children but a rare clinical entity in adults, representing fewer than 1% of intestinal obstructions in this patient population. Colonic lipomas are uncommon nonepithelial neoplasms that are typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy., Case Presentation: A 55-year old man visited our emergency department with severe abdominal pain, multiple episodes of vomiting, abdominal distension. Abdominal ultrasound sonography and computed tomography showed a sausage-shaped mass presenting as a target sign, suggestive of intussusception. Surgery revealed a hard elongated mass in the right colon wihch telescoped in the transverse colon and caused colo-colonic intussusception. Rhigt hémicolectomy was performed and pathology documented a mature submucosal lipoma of the colon. We describe the difficulties in diagnosis and management of this rare cause of bowel obstruction and review the literature on adult intussusceptions., Conclusion: A large submucosal lipoma is a very rare cause of colon intussusception that presents as intestinal obstruction in patients without malignancy. CT and magnetic resonance imaging remain the methods of choice for studying abdominal lipomas, particularly those rising into the layers of the colonic wall. Surgical resection remains the treatment of choice and produces an excellent prognosis.

Introduction: Hydatidosis is endemic in the Mediterranean region including morrocco, the Middle and Far East, Australia, New Zealand, and South America-all areas where animal husbandry is common. Rupture into the abdominal cavity is a rare but serious complication of hydatid disease. The cysts may be ruptured after a trauma, or spontaneously as a result of increased intracystic pressure. Rupture of the hydatid cyst requires emergency surgical intervention., Methods: Fourteen patients received surgical treatment for intraperitoneal rupture of the cysts over a period of 5 years. Age, gender, time to surgery from the onset of the symptoms, laboratory findings, diagnostic procedures, surgical treatment modalities, in-hospital stay, morbidity, mortality and recurrence were evaluated retrospectively., Results: Eight of the patients were men and six were women. All of the patients had signs of peritoneal irritation. One patient (7,14%) had a history of blunt abdominal trauma. Ultrasonography scans revealed intra-abdominal fluid in all cases, intraperitoneal multiple cysts in 11 cases and heterogeneous cavity or cystic structures in the liver in 12 cases. Computed tomography showed multiple cystic lesions in the liver and peritoneum with intra-abdominal free fluid. The ruptured cysts were located in the right lobe of the liver in seven patients, in the left lobe in six patients and in both lobes in one patients. Procedures to fill the cystic cavities were applied after removal of the intraperitoneal fluid. Partial pericystectomy and drainage was the most frequent surgical procedure. No patients died in the early postoperative period. A total of seven morbidities developed in six patients (35.3%). Median hospital stay was 08 days and median follow-up was 12 months. Intra-abdominal recurrence occurred in one case (7.7%)., Conclusions: Rupture of hydatid cysts into the peritoneal cavity, although rare, presents a challenge for surgeons. This pathology should be included in the differential diagnosis of acute abdomen in endemic areas. The operative procedures, either radical or conservative, should be based on the patient's condition, the regional characteristics, and the surgeon's experience. The morbidity and mortality rates of surgical interventions for ruptured hydatid cysts are higher than the rates for elective uncomplicated cases.

Introduction: Duodenal gastrointestinal stromal tumors are uncommon and a relatively small subset of gastrointestinal stromal tumors whose optimal surgical procedure has not been well defined. Because submucosal spread and local lymph node involvement are infrequent in gastrointestinal stromal tumors, wide margins with routine lymph node dissection may not be required. Various surgical procedures for duodenal gastrointestinal stromal tumor, pancreatoduodenectomy, pancreas-sparing duodenectomy, segmental duodenectomy, or local resection, have been described depending on the size and exact site of the lesion., Case Presentation: We present the case of a 65-year-old African woman with a giant gastrointestinal stromal tumor involving the second and third portion of the duodenum successfully treated by partial duodenectomy with duodenojejunostomy. This surgical technique is ideal when a gastrointestinal stromal tumor does not involve the ampulla because it avoids a pancreatoduodenectomy, and has not been previously described for the management of this malignancy. Duodenal gastrointestinal stromal tumor should be suspected in any patient with a duodenal wall mass., Conclusions: Gastrointestinal stromal tumors of the duodenum should be suspected in any patient with a duodenal wall mass. Extramural growth and central ulceration with or without bleeding should alert the endoscopist to the possibility of a duodenal gastrointestinal stromal tumor diagnosis.

Coeliac disease is associated with an increased risk of malignancy, not only of intestinal lymphoma but also of small intestinal adenocarcinoma which is 82 times more common in patients with celiac disease than in the normal population. We report three additional cases of a small bowel adenocarcinoma in the setting of coeliac disease in order to underline the epidemiological features, clinicopathological findings, and therapeutic approaches of this entity based on a review of the literature. The three patients underwent a surgical treatment followed by adjuvant chemotherapy based on capecitabine/oxaliplatin regimen, and they have well recovered.
