[Angiocholitis on hepatic hydatid cyst fistulised in the main bile duct: two case reports]

Hydatid cyst is a zoonosis that frequently affects the liver, which is endemic in several countries such as Morocco. The hepatic hydatidosis can be complicated by angiocholitis, currently, the treatment of choice is endoscopic retrograde cholangio-pancreatography with sphincterotomy. We report two clinical cases of angiocholitis on hepatic hydatid cyst fistulised in the main bile duct which were treated endoscopically with a favourable outcome. Early diagnosis and adequate management can improve the prognosis of these patients.

The Impact of Argon Plasma Coagulation in the Treatment of a Solitary Rectal Ulcer Syndrome Revealed by Massive Hemorrhage

Solitary rectal ulcer syndrome (SRUS) is a rare and chronic rectal condition that can result in a pelvic static disorder. Massive rectal bleeding is a rare manifestation of SRUS. The diagnosis is based on a combination of clinical, endoscopic, and histological findings. The management of bleeding ulcers is usually insufficient with the conventional treatment. Argon plasma coagulation (APC) has been reported to control bleeding. However, its role in healing and improving defecation symptoms is not unanimous in studies. Our case report features a 35-year-old male with terminal constipation and chronic rectal pain, taking laxatives and analgesics, who presented abundant rectal bleeding with hemodynamic instability. The colonoscopy showed two large bleeding rectal ulcers. The histological study of the biopsies was in favor of a solitary rectal ulcer. We have performed multiple sessions of APC. The bleeding was stopped after the first session and there was progressive healing and improvement of the rectal symptoms after other sessions. At 18 months follow-up, the patient is asymptomatic, and no longer uses analgesics and laxatives. Argon plasma coagulation is an effective treatment to control rectal ulcer bleedings. It also improves the healing process and clinical symptoms. However, further controlled studies are needed to support this hypothesis.

Hydatid Cyst of the Pancreas: An Unusual Cause of Abdominal Pain

Pancreas is an uncommon site of hydatid cysts (HCs) even in endemic countries. Primary pancreatic hydatid cysts (PHCs) mainly occur through hematogenous dissemination. Their rarity and the absence of clinical manifestations in most cases explain their challenging preoperative diagnosis. In symptomatic cases, clinical findings may be similar to those of other diseases. We report a case of a 54-year-old female presented with a six-month history of abdominal pain, although her abdominal examination was normal. Radiological imaging revealed a serous cyst in the body and tail of the pancreas. Biliopancreatic endoscopic ultrasound (EUS) suggested a peritoneal hydatid cyst. Intraoperatively, it was diagnosed as a PHC. The patient underwent resection of the PHC and was then placed on albendazole. She did not have any symptoms for the last seven months. Through this case report, we can conclude that peritoneal hydatid cyst of the pancreas should be considered in the differential diagnosis of the cystic lesions of the pancreas. Moreover, surgery achieves a definitive treatment of the disease.

Gastric Duplication Cyst Revealed After an Endoscopic Ultrasound-Guided Fine-Needle Aspiration of a Suspected Mucinous Cystadenoma of the Pancreas

Gastrointestinal duplication is a rare congenital anomaly of the gastrointestinal tract. Gastric duplication cysts (GDCs) are uncommon in adults, and most cases are discovered incidentally. Here, we report a fortuitous discovery of a rare case of an asymptomatic noncommunicating GDC in an adult revealed after an endoscopic ultrasound-guided fine-needle aspiration of a suspected mucinous cystadenoma of the pancreas. A 34-year-old female presented with renal colic. Her abdominal examination was normal. She presented a cystic image at the left lumbar discovered fortuitously during ultrasonography. On uro-computed tomography, there was a suspicion of a pancreatic cystadenoma. Magnetic resonance imaging of the pancreas suggested a mucinous cystadenoma of the pancreatic tail. The endoscopic ultrasound showed a cystic thick-walled formation in the tail of the pancreas. After guided fine-needle aspiration, a split aspect of the gastric wall appeared evoking a GDC. The cytology showed epithelial cells without mucin. Three years later, the patient does not have any gastrointestinal symptoms. GDCs are a rare anomaly, and accurate diagnosis of these cysts is difficult. Surgical resection can offer a definitive diagnosis. The mainstay of treatment is surgery to avoid the risk of malignancy.

Massive Digestive Hemorrhagia Revealing a Gastro-Intestinal Stromal Tumor of the Jejunum

Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that originate from Cajal cells located in different sites of the digestive system. They may occur in the entire gastrointestinal tract. They are diagnosed on the basis of the identification of c-kit-positive cells. We report a case of a stromal tumor of the jejunum revealed by a massive digestive hemorrhagia. Surgical resection is the basis of the treatment of GISTs. Imatinib, a tyrosine kinase inhibitor, is a beneficial treatment after surgical resection of high-risk GISTs.
