Tubulovillous adenoma of the appendix: a case report and review of the literature.

We report the case of a young woman hospitalized for a chronic appendicular syndrome. The histological examination of the resected specimen revealed a rare tumor: tubulovillous adenoma, discovered in 0.02% of all appendectomy procedures. Treatment is most often limited to appendectomy, but in the event of incomplete excision or associated adenocarcinoma, right hemicolectomy may be required. After surgery, a follow-up colonoscopy is recommended due to the higher risk of second gastrointestinal neoplasms in patients with appendicular tumors.

[Sarcoidosis presenting as a splenic pseudotumour]. / Rate pseudotumorale révélatrice de sarcoïdose.

INTRODUCTION: Multinodular splenomegaly is a rare form of extrathoracic sarcoidosis. It may be the presenting feature of the disease. It poses problems of differential diagnosis, in particular with lymphoma, tuberculosis and other granulomatous diseases. In the absence of typical associated lesions, particularly thoracic, histological roof is essential. CASE REPORT: We report the case of a 55-year-old caucasian woman with multinodular pseudotumoural splenomegaly, associated with some small mediastinal lymph nodes and some non-specific parenchymatous pulmonary nodules. The diagnosis of sarcoidosis was made on the basis of splenectomy after eliminating other causes of granulomatosis. CONCLUSION: This case report describes a rare presentation of sarcoidosis and discusses the differential diagnosis of multinodular splenomegaly. It underlines the necessity of an exhaustive aetiological investigation of splenic granulomatosis as the diagnosis of sarcoidosis remains one of elimination.

[Negative pressure therapy in precarious situations. Part 1: abdomen and perineum]. / Therapie par pression négative en situation précaire. 1e partie: abdomen et périnée.

Negative pressure therapy (NPT) is a proven safe and effective technique to promote healing of complex adominoperineal wounds using either an open or closed approach. Specifically designed devices are available in industrialized countries but high cost is a limiting factor for their use in developing countries. The purpose of this report is to describe a simple, easy-to-use technique that is suitable for austere environments. In addition to low-cost, the main advantage of this technique is that it can be performed by anyone using resources readily available in any operating room.

[Current management of sigmoid volvulus in the tropics]. / Prise en charge actuelle du volvulus du sigmoïde en milieu tropical.

Sigmoid volvulus is a frequent medical emergency in Africa. Diagnosis is mostly based on clinical examination and plain abdominal films. Emergency surgical therapy is required for patients presenting severe clinical and radiographic signs. Sigmoidectomy can be performed in a single stage with immediate restoration of digestive continuity or in two stages with colostomy followed by reconstruction several months later. The choice of technique depends on the patient's general condition and intestinal viability, but should also take into account the morbidity, cost, and social consequences associated with colostomy. For patients without severe signs, the method of choice consists of initial detorsion using an endoscope, if available. This strategy allows elective single-stage sigmoidectomy, which is the preferred procedure. Ideally sigmoidectomy after detorsion should be carried out within a few days during the same period of hospitalization and, if possible, using the celioscopic approach.
