fistulas are very rare, account for 1%-4% of the total number of fistulas complicating diverticular diseases, and may be caused by percutaneous drainage of diverticular abscesses without subsequent resection (1).
In our first case, the gas had spread via a complicated diverticulitis, which had caused a colocutaneous
fistula and the perforation of a diverticulum in the abdominal wall, possibly secondary to a weakened abdominal wall and previous surgery.
Postoperatively, the patient developed a colocutaneous
fistula, which was re-excised.
A case of a colocutaneous
fistula: A rare complication of mesh migration into the sigmoid colon after open tension-free hernia repair.
Though very rare, they may lead to morbidity in the form of septicemia, peritonitis, abscess formation, and nephrocolic or colocutaneous
Colonic perforation is one of the most dangerous and rare complications of PCNL, occurring in about 0.3% of procedures.[sup.4] Untreated colonic perforation may lead to renal abscess, nephrocolic or colocutaneous
fistula, peritonitis and sepsis.[sup.4,5] However, there are few reports on the risk factors and management of colonic injury during PCNL.
Those complications are multiple and widespread; they include abdominal wall abscess , broncholithiasis [15-19], lung abscess, empyema , erosion to the back , subdiaphragmatic abscess , liver abscess , splenic abscess, retroperitoneal abscess , peritonitis , granulomatous peritonitis, intestinal obstruction , thrombosis, colocutaneous
fistula , malignancy, dyspareunia, and infertility [30, 31], bladder obstruction, incarcerated hernia , cellulitis , and septicemia .
Laparoscopic nephrectomy (hand assisted) for xanthogranulomatous pyelonephritis with colocutaneous
fistula is a challenging treatment modality .
Major complications associated with PEG tubes include such serious issues as necrotising fasciitis, colocutaneous
fistula, intraperitoneal bleeding, bowel perforation, septicaemia, buried bumper syndrome and aspiration pneumonia.
Two of 4 enterovesical fistulae completely responded and 2 partially responded; 1 of 3 colocutaneous
fistulae had a complete response and 2 did not respond (Table 3).
Enteral nutrition is beneficial with low-output fistulas and fistulas located in the most proximal portion of the small bowel (feeding provided distally), or with colocutaneous
fistula healed spontaneously within 6 weeks.
