Retro-rectal tumors are asymptomatic in most cases. Rarely they manifest as a rectal syndrome as in the case of our patients, or as a result of superinfection or malignant degeneration. Positive diagnosis is based on digital rectal examination, rectoscopy, echo-endoscopy and especially pelvic MRI and CT scan. Once the diagnosis has been made, surgical removal is required as soon as possible. Several surgical approaches have been proposed: perineal or transacral approach (adopted in our first case); abdominal approach or combined approach. The decision of the approach depends on the size of the tumor, its location and its histological nature. In case of malignant degeneration, the prognosis is poor. We report 3 cases of retro-rectal tumors operated on in the department of digestive cancer surgery and liver transplantation of the CHU Ibn Rochd of Casablanca with the support of data from the literature.

Trauma to the pancreas is rare, occurring in 0.2 to 3% of abdominal injuries. They are associated with high mortality and morbidity if diagnosis is delayed. Their clinical symptomatology is atypical. Abdominal CT scans can diagnose pancreatic injury and rupture of the main pancreatic duct. It is important that surgeons are aware of the issues and principles of management of pancreatic injury. We report the case of a 33-year-old patient with no previous pathological history. Admitted for a closed abdominal contusion following a road traffic accident with an abdominal impact point without initial loss of consciousness and generalized abdominal contracture. Abdominal CT scan showed a hypodense area in the tail of the pancreas not enhanced after contrast injection, possibly related to a pancreatic fracture and a medium-sized peritoneal effusion. The patient underwent corporo-caudal pancreatectomy with splenic preservation. Postoperative follow-up was favorable. The clinical evolution judged on regular controls was favorable over a period of 2 years. We would like to share a very difficult clinical case and our experience with the support of the literature. This is a challenge to clinicians and surgeons above all.

Neuroendocrine tumours (NETs) are characterised by their ability to secrete hormones. There is a wide variety of NETs that can develop in any organ of the digestive system. NETs of the appendix are rare with an estimated incidence of 0.15 to 06 cases/year per 100,000 people and are often seen in young adults with a male predominance. Most NETs of the appendix are asymptomatic and usually discovered incidentally during appendectomy. Treatment is by surgical removal of the tumour to a healthy margin in accordance with the principles of carcinology. We report on a case of a 24-year-old female patient. She was admitted with generalized abdominal pain originating in the right iliac fossa with a B.P. of 0 and a fever of 38°C. The abdominal and pelvic CT scan showed acute appendicitis with a discrete agglutination of the loop around the appendix and an effusion of the right iliac fossa and pelvis of medium abundance. The biological work-up showed a hyperleukocytosis with a predominance of neutrophils. The patient underwent ileo-caecal resection, ileo-colostomy in double gun barrel after an exploration which revealed a mass of appendicular cystic appearance "suspicion of appendicular mucocele?" with a purulent peritoneal effusion and false membranes in the inter-anses. Pathological examination showed a proliferation of organoid architecture suggestive of a neuroendocrine tumour measuring 4 mm in length.
