Injuries of the biliary system are rare. They can broadly be divided into traumatic biliary injuries and iatrogenic biliary injuries. Former are usually part of associated abdominal trauma, blunt or penetrating, and latter are consequence of surgical, endoscopic or invasive radiological diagnostic or therapeutic procedures done in various liver, pancreatic or disorders or the part of upper gastrointestinal system. They occur more commonly than traumatic injuries but still are rare. Those injuries represent important aspect in healthcare system because of their complexity and diversity in management, associated morbidity and mortality and expenditure in healthcare systems. This chapter will put focus on those injuries, including their classification, etiology and mechanism of occurrence, clinical presentation, diagnosis, treatment options, postoperative complications, and, when iatrogenic injuries are concerned, methods for prevention of those injuries.

Complex anal fistulas present a challenge to even a seasoned colorectal surgeon due to high rate of recurrence and a real possibility of fecal incontinence if treated with conventional methods (e.g., fistulotomy, fistulectomy, seton placement). Although the illness is benign in nature, it can significantly decrease patient’s quality of life because of symptoms like pain and soiling. Given those facts, minimally invasive or sphincter preserving methods of treatment were introduced. Some of these include: Video-assisted anal fistula treatment (VAAFT), ligation of intersphincteric fistula tract (LIFT), Fistula-tract laser closure (FILAC), rectal advancement flap (RAF), treatment with platelet cells and combinations of techniques. This chapter would be an overview of these novel techniques with reference to latest clinical trials and meta-analyses.

Anal fistulas are still a huge challenge for surgeons because of their high incidence, high recurrence rate, prolonged healing time and possible complications such as fecal incontinence. Even though many surgical options have been described, we still do not have the standardized procedure. Patients who suffered from this problem have a low quality of life because of constant anal pain and soiling from anal tracts. Aside from cryptoglandular etiology, fistulas associated with Crohn’s disease are separate entity that requires a multidisciplinary approach. This chapter will be an overview of modern approaches in anal fistula treatment regardless of etiology with special consideration on how to avoid adverse outcomes and to improve patients’ quality of life.
