Torsion of wandering spleen, an unusual cause of acute abdomen; a report of two cases.

BACKGROUND: Wandering spleen is an uncommon entity that is rarely considered in the evaluation of patients with acute abdominal conditions. OBJECTIVE: To report two cases of wandering spleen presenting with acute abdominal pain. METHODS: The clinical records of the patients including preoperative evaluation, intra-operative findings and postoperative care were reviewed RESULT: A 6 year old boy presented with right lumbar pain which worsened over a 36 hour period with findings of a tender right lumbar mass. Abdominal ultrasound showed a mass with echogenicity consistent with that of the spleen with no blood flow and an empty splenic bed. The pre-operative diagnosis was torsion of a wandering spleen. The second case was that of a 42 year old woman who presented with severe colicky lower abdominal pain which worsened over three days with a background history of progressively increasing lower abdominal mass which was tender and about 26 week gestational size at presentation. The initial diagnosis was torsion of an ovarian cyst. Abdomino-pelvic Ultrasound scan showed a heterogeneously hypo-echoic mass overlying the uterus and the left ovary with no blood flow. The presence of wandering spleen with torsion of the vascular pedicle was confirmed at laparotomy in both instances. Splenectomy was performed in both cases with good recovery. CONCLUSION: Torsion of a wandering spleen poses a diagnostic challenge. A high level of suspicion is required to make a diagnosis and institute appropriate treatment.

A review of the management of perforated duodenal ulcers at a tertiary hospital in south western Nigeria.

BACKGROUND: Gastro-duodenal perforations are common and may complicate peptic ulcer disease. Management is often by surgical closure. OBJECTIVE: To determine the patterns of presentation and mode of management of duodenal ulcer perforations. METHODS: Retrospective review of patients with duodenal ulcer perforations seen at the Obafemi Awolowo University Teaching Hospital between June 2001 and July 2011. Patients' records were reviewed for demography, duration of disease, probable risk factors, type of surgery and complications. Data obtained was analyzed using SPSS 15.0. RESULT: Forty- five patients were reviewed. There were 37 males (82.2%). Mean age was 39.7years (range 15-78years). There were 10 (22.6%) students and 8(17.8%) farmers. NSAIDs abuse (11), previous peptic ulcer disease (2), and no prior dyspeptic symptoms (20) constituted 24.4%, 4.4% and 44.4% respectively of cases. Seven (16%) patients presented less than 24 hours of onset of illness. Forty one perforations (91.1%) involved the first part of duodenum. Twenty two (49%) patients had Graham's omental patch. We had one (2.2%) failed repair and six (13.3%) mortalities. CONCLUSION: Late presentation of duodenal ulcer perforation is common with high mortality. Pragmatic surgical intervention with Graham's omentopexy with broad spectrum antibiotics is still commonly practiced.
