[Retrorectal tumors in adults about 3 cases]

Retrorectal tumors [RRT] constitute a topographic entity grouping benign andmalignant tumors that are congenital for the majority, and developing in presacral retrorectal space. The multiplicity of the embryologic theories, the difficulty of their histological classification, as well as the diagnostic and therapeutic delays, will be illustrated by three new cases in the visceral surgery service of the Military Hospital of Instruction Mohammed V of Rabat. Their topographic diagnosis and extension rests on the abdomino-pelvic tomodensitometry and the imagery by magnetic resonance in order to determine the nature and especially the reports of the tumor. Their treatment rests on the surgical excision systematically. The forecast of these tumors depends of their histological nature and the quality of the surgical excision

[Primary linit plastica of the rectum in child]

The plastic linit is defined-as the infiltration of the wall of a hollow body by a diffuse anaplastic cancer . Its most frequent seat is gastric. The rectal primitive linit is very exceptional. All diagnosis, therapeutics and prognosis aspects this affection were discuss. A 12 year ad girl is hospitalized for primitive rectal linit. She was treated by abdominoperineale amputation after radiochemotherapy. The patient have received adjunct chematherapy. The out come was simple without recurrence after 4 months. The plastic linit of the rectum is a little differentiated shape of adenocarcinoma. The diagnosis is provided on a major biopsy and the absence of gastric attack. The farecast is very bad in spite of intencive treatment, associating surgery, radiotherapiy and chemotherapy

inflammatory pseudotumors of the colon

The inflammatory pseudotumors of the colon are very rare benign lesions, of unknown etiology and whose differential diagnosis is difficult with the adenocarcinoma. Young girl patient of 12 years old, presented with mass in the right iliac fossa, the preoperative assement was in favour of right colon malignancy with retro peritoneal extension. Right colectomy was done, histological examination confirmed the diagnosis of inflammatory pseudotumors of the colon. The inflammatory pseudotumors of the colon are benign tumor they can be the origin of local and general signs colonic localization is exceptional and etiology remains unknown. Surgery is necessary to obtain an histological diagnosis of the lesion and to eliminate malignant tumor

Pilonidal sinus

Pilonidal sinus is a frequent benign disease, with a localization often sacrococcygeal. Its etiopathogensis is still badly clarified. Diagnosis is generally easy in typical forms: purulent flow by an opening situated at the level of inter gluteal furrow and containing some hairs. Some diagnosis traps secondary to aberrant localizations should be known. Open surgical excision and cicatrizationnn is the treatment of choice. To this effect, we report 29 cases of pilonidal sinus operated on by this method between 1990 and 1999. This pathology occupies the fourth place of proctological diseases 75% of the patients are young, aged between 20 and 40 years. Male predominance is clear with a sex ratio H/F=1,9. Chronic purulent flow is the main symptom found in 82,23 of cases. After a retreat of one to 10 years, a case of fake recurrence has been noted. A second resection without closure has been successfully done

Thrombosis of the portal system following splenectomy

Venous thrombosis of the portal system following splenectomy is uncommon, with an incidence of 0,2 to 6%. The clinical presentation varies greatly and the diagnosis is difficult and must be confirmed by doppler ultrasonography. The authors report the study of 2 observations. Diagnosis, therapeutic and prophylactic aspects of this complication of splenectomy are discussed
