We aim to report a rare case of colonic perforation post percutaneous nephrolithotomy (PCNL) and its conservative management.We report a 63-year-old Malay, thalassemia carrier male who underwent an uncomplicated left PCNL fora left renal stone. On second postoperative day, clinically evidence of subcutaneous emphysema. Serial CXR imaging confirmed presence of air under diaphragm. Small colonic perforation was diagnosed which subsequently developed localized collection retroperitoenally. He was successfully treated with non-operative management including intravenous antibiotic, surgical drainage and good nutrional has successfully support healed the collection. Serial CT renal protocol showed a healed retroperitoneal collection and patient made a good clinical recovery.PCNL has promising stone clearance rate. However, it carries complications. A rare yet important complication; colonic perforation is a serious complication that if detected earlier, good clinical recovery can be achieved conservatively.
Henoch-Schonlein purpura or anaphylactoid purpura is a systemic vasculitis of unknown cause that affects small vessels and mainly involves the skin, joints, gastrointestinal tract and kidneys. Gastrointestinal involvement occurs in more than half of patients and is thought to be related to edema and intramural haemorrhage. Radiologically the gastrointestinal findings are mainly those of bowel ischemia with thumbprinting and bowel wall oedema. Although this disease is usually treated conservatively, aggressive intervention is occasionally performed because of acute abdominal symptoms due to complications, such as perforation, intussusception and obstruction. This report illustrates a case of Henoch-Schonlein purpura with acute abdominal symptoms due to intussusception.
The wide use of computed tomography (CT) scanning for patients with blunt abdominal trauma can reveal incidental findings that vary in their importance. We evaluated these findings, how it was reported by radiologists and its implication on the trauma care. In 30 out of 154 patients, 32 incidental findings were discovered (19.5%). Out of these 32 findings, only 3 cases (9.4%) were considered significant and required immediate attention from the managing team. In all these 3 cases, the findings were described in the body of the report and highlighted in the conclusion section at the end of the radiology report. However, similar reporting style was used in only 58.4% of cases with moderate clinical concern and 23.5% of cases with little clinical concern. In 41.2% of cases with little concern, the incidental findings were not mentioned in the radiology report. In conclusion, incidental findings in CT scan performed for blunt abdominal trauma were common but many were clinically insignificant. There is little consistency in radiology reporting of these findings especially those with moderate and little clinical concern.
