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.

Splenic lymphangiomas as a common indication for splenectomy: a case series with literature review.

BACKGROUND: Splenic lymphangiomas (SL) are very rare benign cystic lesions found in pediatric population. Their occurrence in adults is exceptional. Splenectomy is the common management of splenic lesions for diagnostic and/or therapeutic purpose. Our aim is to report additional cases of SL diagnosed on splenectomy specimens at our Pathology laboratory with literature review. METHODS: This is a retrospective study including all cases of splenectomy recorded at our Pathology laboratory (June 2020-August 2022). We performed a comparison of clinicopathological features between patients with SL and those with other benign splenic diseases. RESULTS: Sixteen cases of splenectomy were included. The mean age was 30.25 years (range of 6-70 years). The final histopathological diagnoses were congestive spleens in all cases of sickle cell disease (SCD) (5/16 patients, 31.25%), splenic cystic lymphangiomas (4/16 patients, 25%), capsular splenic infiltration by gastric and colic cancers (3/16 cases, 18.75%), splenic abscess (2/16 cases, 12.5%) and splenic rupture with subcapsular hematoma (1/16 patients, 6.25%). 12/16 patients (75%) had benign splenic conditions (4/12 with SL, 5/12 with SCD, 2/12 with abscess and 1/12 with splenic trauma). Patients with SL were older than those with other benign splenic conditions (mean age of 28.27 years versus 20.87 years). Also patients with SL presented with massive splenomegaly (mean splenic weight of 1675 g versus 418.75 g, mean splenic size of 19.62 cm versus 14.63 cm). Open surgery was performed in 15/16 patients (93.75%). CONCLUSION: Unlike previous studies, our series shows that SL are a common indication for splenectomy and occur in older patients with massive cystic splenomegaly. Open splenectomy is still an usual surgical practice in our country.
