In a retrospective analysis it was found that not all patients with penetrating bull-gore injuries of the abdomen need exploration by formal laparotomy. A policy of selective conservatism was followed in the management of 18 out of 20 patients with bull-gore injuries of the abdomen in whom peritoneal breach was established either on presentation or by digital exploration of the wound. Formal laparotomy was reserved for specific clinical indications. Out of the 18 cases, 14 (78 per cent) were successfully treated non-operatively with wound excision, simple closure of the wound, and careful repeated clinical evaluation. There was no mortality in this group. Four cases (22 per cent) were explored; three of these had indications for exploration on presentation and the fourth was explored 4 days after admission. The latter was the only death that occurred in the series; the cause of death was probably pulmonary embolism. Omental and/or bowel evisceration occurred in 11 out of 18 cases (61 per cent). However, this was not considered an indication for exploration and all 11 cases were treated by simple replacement of omentum or bowel into the abdominal cavity. Penetrating abdominal bull-gore injuries can be managed safely by a policy of selective conservatism, reserving formal laparotomy for specific clinical indications.

Chronic dyspnea is defined as dyspnea lasting more than one month. In approximately two thirds of patients presenting with dyspnea, the underlying cause is cardiopulmonary disease. Establishing an accurate diagnosis is essential because treatment differs depending on the underlying condition. Asthma, congestive heart failure, chronic obstructive pulmonary disease, pneumonia, cardiac ischemia, interstitial lung disease, and psychogenic causes account for 85 percent of patients with this principal symptom. The history and physical examination should guide selection of initial diagnostic tests such as electrocardiogram, chest radiograph, pulse oximetry, spirometry, complete blood count, and metabolic panel. If these are inconclusive, additional testing is indicated. Formal pulmonary function testing may be needed to establish a diagnosis of asthma, chronic obstructive pulmonary disease, or interstitial lung disease. High-resolution computed tomography is particularly useful for diagnosing interstitial lung disease, idiopathic pulmonary fibrosis, bronchiectasis, or pulmonary embolism. Echocardiography and brain natriuretic peptide levels help establish a diagnosis of congestive heart failure. If the diagnosis remains unclear, additional tests may be required. These include ventilation perfusion scans, Holter monitoring, cardiac catheterization, esophageal pH monitoring, lung biopsy, and cardiopulmonary exercise testing.
