Vesicoenteric fistula is a rare complication of bladder squamous cell carcinoma. We report the case of a 70-year-old male who complained of painless, total gross hematuria. Abdominopelvic computed tomography (CT) revealed an approximately 2.7-cm lobulated and contoured enhancing mass in the bladder dome. We performed partial cystectomy of the bladder dome after transurethral resection of the bladder. The biopsy result was bladder squamous cell carcinoma, with infiltrating serosa histopathologically, but the resection margin was free. Postoperatively, follow-up CT was done after 3 months. Follow-up CT revealed an approximately 4.7-cmx4.0-cm lobulated, contoured, and heterogeneous mass in the bladder dome. A vesicoenteric fistula was visible by cystography. Here we report this case of a vesicoenteric fistula due to bladder squamous cell carcinoma.

A 74-yr-old woman presented with fever and abdominal discomfort. She was in a septic condition caused by urinary tract infection. Her computed tomogram of the abdomen revealed features of hydronephrosis with ureteral stones in both kidneys. During percutaneous nephrostomies, right pyeloduodenal fistula (PDF) was diagnosed. Elective surgery was originally planned but the patient was in a poor condition to undergo surgery. Instead, 2 times endoscopic clipping and ligation by endoloop were applied with parenteral antibiotics for the fistula lesion. On admission day 30, she was discharged from the hospital after confirmation of no more contrast leakage on fistulography. We reviewed the literature and discuss the etiologies, clinical presentations, diagnosis, and treatment of PDF.

OBJECTIVE: We wanted to evaluate the efficacy of stent placement using the coaxial technique with a stiff, long introducer sheath in patients with technical failure using an angiographic catheter for the obstructions proximal to the descending colon. MATERIALS AND METHODS: Self-expandable metallic stent placement was attempted under fluoroscopy-guidance in 77 consecutive patients who had malignant colorectal obstruction. Stent placement was performed using an angiographic catheter and a guide wire. If the angiographic catheter could not be advanced over the guide wire into the obstructive lesions proximal to the descending colon, then a 6-Fr introducer sheath was used. The technical success rate, the clinical success rate and the complications were analyzed. RESULTS: Successful stent placement was achieved in 75 of 77 patients (97%). The angiographic catheter failed to advance into the obstructive lesions of 11 patients (M:F = 7:4; mean age, 65.5 years) whose lesions were at the level of the splenic flexure or transverse colon. Therefore, the coaxial technique was implemented in all these 11 patients using a 6-Fr stiff introducer sheath and then the stent placement was successful. There were no complications related to the use of a stiff introducer sheath. Clinical success, which was defined as relief of clinical obstructive bowel symptoms, was obtained within 24 hours in all of patients. CONCLUSION: The coaxial technique using a stiff introducer sheath can increase the technical success of fluoroscopy-guided, self-expandable metallic stent placement in patients with colonic obstruction proximal to the descending colon.

Erlotinib is accepted as a standard second-line chemotherapeutic agent in patients with non-small cell lung cancer who are refractory or resistant to first-line platinum-based chemotherapy. There has been no previous report of bowel perforation with or without gastrointestinal metastases related to erlotinib in patients with non-small cell lung cancer. The exact mechanism of bowel perforation in patients who received erlotinib remains unclear. In this report, we report the first case of enterocutaneous fistula in a female patient with metastatic non-small cell lung cancer 9 months, following medication with erlotinib as second-line chemotherapy.

A broad spectrum of colonic complications can occur in patients with colon cancer. Clinically, some of these complications can obscure the presence of underlying malignancies in the colon and these complications may require emergency surgical management. The complications of the colon that can be associated with colon cancer include obstruction, perforation, abscess formation, acute appendicitis, ischemic colitis and intussusception. Although the majority of these complications only rarely occur, familiarity with the various manifestations of colon cancer complications will facilitate making an accurate diagnosis and administering prompt management in these situations. The purpose of this pictorial essay is to review the CT appearance of the colonic complications associated with colon cancer.

Arterio-enteric fistula is a very rare cause of massive lower gastrointestinal hemorrhage. We report here on a case of massive hematochezia caused by iliac arterio-colic fistula in a 60-year-old woman who had a recent history of spinal surgery for herniated nucleus pulposus. Abdomen computed tomography showed the extravasation of radiocontrast media from right iliac artery encased by an intraabdominal abscess into the adjacent dilatated colon. Also, diagnostic angiography revealed the active extravasation of radiocontrast media via a fistula between right iliac artery and colon. Although successful endovascular exclusion of the fistula with stent graft and coils was performed, disseminated intravascular coagulation and multi-organ failure were developed.

BACKGROUND/AIMS: A stercoral perforation of the colon (SPC) is a rare, life-threatening disease. The aim of this study was to represent the definition of SPC and help the diagnosis and treatment of this condition. METHODS: We reviewed 92 medical records of patients who underwent operation due to colonic perforation from January 2000 to February 2009 retrospectively. Maurer's diagnostic criteria were used for the diagnosis of SPC. RESULTS: Eight patients (8.7%) were diagnosed as SPC. The age of the patients ranged from 59 to 85 years old. All of the patients were female and had a history of long-standing constipation. Only two patients (25%) were diagnosed as SPC preoperatively. The site of perforation of all patients was sigmoid colon. The methods of operation were Hartmann's procedure (7 cases), and primary repair with sigmoid loop colostomy (1 case). There were one recurrence and two deaths (25%) due to sepsis and multiple organ failure. CONCLUSIONS: SPC should be considered in chronically constipated, and bedridden patients who present with acute abdomen. Hartmann's procedure is the treatment of choice in most situations. Mortality is high but can be minimized with early definitive surgery.

Mesenteric lymphangiomas are rare abdominal masses that are seldom associated with small bowel volvulus, and especially in adult patients. We report here on an unusual case of small bowel volvulus that was induced by a mesenteric lymphangioma in a 43-year-old man who suffered from repeated bouts of abdominal pain. At multidetector CT, we noticed whirling of the cystic mesenteric mass and the adjacent small bowel around the superior mesenteric artery. Small bowel volvulus induced by the rotation of the mesenteric lymphangioma was found on exploratory laparotomy. Lymphangioma should be considered as a rare cause of small bowel volvulus in adult patients.

Intestinal obstruction is a common surgical emergency. Transmesenteric hernia is an unusual cause of bowel obstruction that may result in irreversible damage of the bowel and a fatal outcome. Once incarceration of the bowel occurs, strangulation and gangrene follow immediately. The mortality rate associated with this condition is about 15%, but in the presence of gangrene of the bowel, the mortality rate is more than 50%. An accurate preoperative diagnosis of a transmesenteric hernia is very difficult and rarely made. Therefore, in patients with small bowel obstruction, in the absence of a history of previous surgery to suggest adhesions or an external hernia, the possibility of a transmesenteric hernia must be considered. We describe a case with gangrene of a long segment of the small bowel caused by a transmesenteric hernia through a large defect of small bowel mesentery in a child.
