Diagnostic and therapeutic approach to abdominal masses in a country with limited resources.

OBJECTIVE: To report the diagnostic and therapeutic approach for the management of abdominal masses in the General Surgery department of the Niamey General Reference Hospital (HGR). MATERIALS AND METHODS: This were a retrospective and preliminary study of 2 years and 3 months on patients operated for abdominal masses in the General Surgery department of the HGR. A palpable mass and/or its size on imaging (40 mm) were the inclusion criteria. RESULTS: Abdominal masses accounted for 6.7% (n = 53) of other pathologies. The average age of the patients was 41.26 years, with a standard deviation of 14.2 and a female predominance of 75.5% (n = 40) with a sex ratio of 0.32. The abdominal mass was clinically palpable in 75.5% (n = 40). Abdominal pelvic ultrasound was performed as a first step in all patients and in 75.5% (n = 40) it specified the origin of the mass. Contrast-enhanced abdomino-pelvic CT scan, performed in 52.8% of patients (n = 28) and in 89.3% (n = 25) specified the preoperative diagnosis. The most frequent etiologies were uterine fibroids, 35.8% (n = 19). In 5.6% (n = 3) the diagnosis was not precise preoperatively despite the two imaging studies, and these patients had underwent exploratory laparotomy. Surgery was the initial therapeutic approach for all patients, and laparoscopy accounted for 22.6% (n = 12). Postoperative complications occurred in 7.5% (n = 11). The death rate was 5.6% of cases (n = 3). CONCLUSION: Imaging remains important in the etiological research for abdominal masses. Definitive treatment remains surgical; mortality would be linked to the malignant nature and the significant volume of the mass.

Appendiceal mucocele as an exceptional cause of ileocecocolic intussusception in adults: a case report.

BACKGROUND: Intussusception is a rare condition in adults, accounting for 5% of intestinal intussusception and being responsible for approximately 1% of all adult bowel obstructions. Neoplastic origin is the most common etiology of intestinal intussusception in adults, unlike pediatric intussusception, which is usually idiopathic. Intussusception due to the appendiceal mucocele is exceptional, and only a few cases have been reported in the medical literature. CASE PRESENTATION: We report the case of a 25-year-old black African male patient with no medical history. He presented to the emergency department for abdominal pain, nausea, and bilious vomiting. The abdominal examination revealed typical signs of acute bowel obstruction. Enhanced abdominopelvic computed tomography showed an invagination of the last ileal loop, cecum, and ascending colon into the lumen of the transverse colon, with a rounded image with hypodense content and some calcifications compatible with an appendiceal mucocele. An emergency exploratory laparoscopy was performed and confirmed the ileocecocolic intussusception. Right hemicolectomy and ileocolic anastomosis were performed. The patient recovery postoperatively was uneventful, and he was discharged 4 days later. Histological examination of the surgical specimen confirmed the diagnosis of mucinous cystadenoma. CONCLUSION: The symptoms of bowel intussusception with the appendiceal mucocele as the lead point in adults are similar to any other bowel intussusception. Differential diagnosis is often carried out thanks to the injected abdominal computed tomography scan.
