Clostridium septicum foot gangrene associated with colorectal cancer.

INTRODUCTION: Since the second half of the 20th century, an association between the occurrence of Clostridium septicum and Streptococcus gallolyticus infections in patients with colorectal cancer has been described in specialist literature. Infections are manifested by bacteremia, septic embolism, cellulitis, myonecrosis, and gas gangrene of the limbs. MATERIAL AND METHODS: The authors present a case of a rare association between lower limb gangrene caused by the septic embolization of a Clostridium septicum infection and malignancy of colon ascendens in a polymorbid patient. Gangrene of the lower limb led to septic shock requiring acute amputation treatment. After managing the acute condition, the patient was operated on for a malignant colon tumour. DISCUSSION: The process of carcinogenesis often takes years and is almost asymptomatic. The occurrence of S. bovis/S. equinus (SBSEC) and C. septicum bacteremia, respectively, is relatively rare, but their presence is often associated with the occurrence of malignancy, most often of the lower gastrointestinal tract. This paraneoplastic symptom may be the first manifestation of a malignant disease. The effect of exotoxins can lead to sepsis or even septic shock with a mortality of 48-56%. CONCLUSION: Clostridium septicum and Streptococcus gallolyticus infections are rare in clinical practice. However, their presence can be a first paraneoplastic symptom, and therefore the doctor should look for a possible oncological disease when they are detected. The main diagnostic methods include colonoscopy and imaging, especially CT scan.

Jejunal diverticulosis: A rare cause of massive bleeding.

INTRODUCTION: Jejunal diverticulosis is a rare diagnosis that occurs mainly in old age, more often in men than in women. It is usually an incidental diagnosis of unclear aethtiology. In some cases, visceral myopathy can also be the cause. It is most often manifested by abdominal pain and bleeding. Bleeding from the small intestinal diverticula represents only 0.6-5% of all small intestinal bleeding. CASE REPORT: The authors describe the case of a 66-year-old man with massive gastrointestinal bleeding who did not respond to conservative hemostyptic treatment. Following negative gastrofibroscopic and colonoscopic examinations, an angioCT examination was indicated, which revealed a source of bleeding in the jejunal diverticula. The patient was indicated for surgical treatment. The extent of bleeding was determined by perioperative enteroscopy and subsequently, the affected jejunal segment was segmentally resected with a primary anastomosis. CONCLUSION: Bleeding from the jejunal diverticula is a very rare diagnosis, which poses challenges in the diagnostic process in particular. Capsule enteroscopy plays an important role in the diagnosis, as well as CT angiography and scintigraphy in the event of massive bleeding. In addition to conservative treatment, the embolization of a bleeding vessel may subsequently be used in therapy. In indicated cases, surgical resection treatment is also possible.
