Hydatid cyst rupture in peritoneal cavity is a rare complication. Imaging assessment has an important role in diagnosis but clinical signs are mandatory. A quick diagnosis and emergency surgery can decrease postoperative death. Surgery and postoperative care constitute the basis of treatment.

HighlightsAdenosquamous carcinoma is a rare colorectal tumor with both glandular and squamous histologic component.To the best of our knowledge only few cases have been reported in the literature till date.Adenosquamous carcinoma is a rare colorectal neoplasm with non-specific complaints.Its clinicopathologic behavior is not understood.Preoperative diagnosis is often difficult. Surgical resection remains the mainstay of treatment.

Liver hydatid cyst with cystobiliary communication and superadded acute cholangitis is a serious clinical problem requiring the early diagnosis and surgery in the absence of endoscopic therapy.

Duodenal metastases from primary lung carcinoma are uncommon. They usually occur in terminal‐stage disease. Bleeding, as the first presentation of duodenal metastases, is rare. This case reports a rare mechanism of upper gastrointestinal bleeding due to a metastatic involvement of the duodenum and gastroduodenal artery. A 58‐year‐old man with a past medical history of pulmonary carcinoma presented an episode of hematemesis of great abundance with melena. On physical examination, he was afebrile and pale. The biological data found an anaemia with haemoglobin at 6 g/dL. The upper gastrointestinal endoscopy revealed a congestive duodenal lesion with signs of recent bleeding. An angio CT scan localized the bleeding from the gastroduodenal artery. A few hours later, the patient presented a recurrent episode of hematemesis with deglobalization. So we performed a radiologic embolization of the gastroduodenal artery. Haemorrhage as the first presentation of small bowel metastases is rare, especially when these are located in the duodenum, with a poor prognosis. Radiological embolisation could be the best choice for treatment.

Introduction and importance: Traumatic abdominal wall hernia (TAWH) also known as blunt abdominal TAWH is uncommon. The clinical diagnosis is difficult. The authors present a case report of posthigh-energy abdominal blunt trauma causing a TAWH. Case presentation: A 36-year-women, with unremarkable past medical history, was presented to the Emergency Department after a stuck in high-speed two automobiles. She was hemodynamic, respiratory, and neurologically stable. The BMI was 36 kg/m². The abdomen was not distended with an ecchymotic lesion on the right flank. The thoracic abdominal and pelvic computed tomography (CT) scan revealed a rupture in the lateral abdominal wall muscles with a TAWH in the location of the skin ecchymoses. There was no visceral lesion or intraperitoneal fluid. A conservative treatment was indicated. The follow-up was uneventful, with hematoma resorption and no cellulitis or abscess. The patient was discharged after 1 week. An abdominal repair will be planned using a mesh. Clinical discussion: TAWH is a rare entity. The best imaging modality for diagnosis is the CT scan allowing classification of the hernia and a screen for other injuries. The presence of an isolated TAWH must lower the threshold to closely monitor or to operatively explore, given the high rate of false-negative findings at imaging features. Conclusion: TAWH should be suspected behind any blunt abdominal trauma with high energy. CT scan and ultrasound were helpful for diagnosis and the only curative treatment is surgery to avoid complications.

Les duplications de l'appareil digestif sont les malformations congénitales rares qui peuvent toucher tout l'appareil digestive depuis la bouche jusqu’ à l'anus. Certaines duplications sont asymptomatiques et sont diagnostiqués dans la plupart des cas pendant l'enfance. La prise en charge de la duplication gastrique est essentiellement chirurgicale. Le traitement de choix est l'exérèse complète de la duplication gastrique. Les auteurs rapportent un cas inhabituel de duplication gastrique complètement reséquée par laparoscopie. A notre connaissance, ceci est le premier cas d'une duplication gastrique traitée avec succès par laparoscopie dans la littérature Tunisienne. La Résection laparoscopique peut être ajoutée à l'arsenal thérapeutique dans le traitement chirurgical de duplications du tube digestif.
