Colocutaneous fistula following Clostridioides difficile infection managed as an 'autocolostomy': a novel approach to a recognised complication.

Colocutaneous fistula is a rare entity in colorectal disease. We present a case of colocutaneous fistula in a patient whose postoperative course following a laparoscopic anterior resection for sigmoid cancer was complicated by Clostridioides difficile colitis. During the follow-up period, it was found that his bowel contents were preferentially discharging through this fistula which had taken up the role of an 'autocolostomy'. Given the physiological impact of an additional surgical procedure, a definitive repair of the fistula was deferred and instead the patient was taught to manage it in keeping with general principles of stoma care. Over the subsequent follow-up period, he has now developed a large parastomal hernia and is being considered for definitive repair.

De Garengeot's hernia in an elderly woman as a diagnostic challenge: a review of literature.

De Garengeot's hernia is the presence of an appendix in a femoral hernia and can be a rare cause of an acute groin swelling. Here, we present a case report of an elderly woman who was referred to us with a short history of a painful, tender lump in the right groin associated with nausea and vomiting. Her inflammatory markers were raised, and to establish a final diagnosis, an urgent CT scan was requested which showed a blind ending tubular structure in a hernia sac. She was taken to the theatre for urgent exploration of the groin which revealed that it was a femoral hernia, the sac of which contained gangrenous appendix, the base of which could not be accessed through the groin incision and, therefore, a lower midline laparotomy incision was made and a formal appendicectomy was done.

Unusual case of cholecystocolonic fistula secondary to megabowel.

Cholecystocolonic fistula with associated idiopathic megabowel (megacolon and megarectum) is a rare presentation as acute large bowel obstruction. Frequently presenting with chronic constipation, acute bowel obstruction is rarely encountered in the presence of concomitant cholecystocolonic fistula. This presents diagnostic and management difficulties with no consensus on appropriate surgical approach. This case highlights the outcomes following emergency total colectomy and subtotal cholecystectomy as a single-stage procedure for a 68-year-old man presenting with cholecystocolonic fistula secondary to idiopathic megabowel as acute large bowel obstruction.

Application of autologous derived-platelet rich plasma gel in the treatment of chronic wound ulcer: diabetic foot ulcer.

The treatment of chronic wounds remains problematic, despite new insight into the cellular and molecular basis of wound healing. Although the aetio-pathogenesis of chronic wounds is said to be multi-factorial, it is evident from literature that effective and adequate wound debridement has produced the most consistent effect in chronic wound treatment. There is a growing body of evidence that suggests that wound healing in chronic diabetic foot ulcers is growth factor dependent and that the therapeutic delivery of these growth factors to wounds topically, has the potential ability to accelerate wound healing in conjunction with conventional wound care. Autologous derived platelet concentrate is activated to release growth factors that are stored in the platelet granules. These secretory proteins include cytokines and growth factors such as transforming growth factor-beta, vascular endothelia growth factor, platelet derived growth factor, and so on. The enhancement of soft tissue healing by the application of autologous derived platelet rich plasma gel (APG) is supported by basic science and some clinical studies. This review article will attempt to provide a concise report of current concepts on the use of APG in treating chronic ulcers.
