In order to relieve mechanical obstruction caused by rectal carcinoma, a bare rectal stent was inserted in the sigmoid colon of a 70-year-old female. The proce-dure was successful, and for one month the patient made good progress. She then complained of abdominal pain, however, and plain radiographs of the chest and abdomen revealed the presence of free gas in the ubdiaphragmatic area. Surgical findings showed that a spur at the proximal end of the bare rectal stent had penetrated the rectal mucosal wall. After placing a bare rectal stent for the palliative treatment of colorectal carcinoma, close follow-up to detect possible perforation of the bowel wall is necessary.

Endoscopic tattooing with India ink is generally regarded as a safe procedure that enables ready identification of endoluminal cancer from the serosal surface. However, significant complications have been reported, including local inflammatory pseudotumor formation, peritonitis, rectus muscle abscess, small bowel infarction, and phlegmonous gastritis. Although the mechanism of complication is not completely understood, it may be related to the chemical compounds contained in the ink solution and enteric or extraenteric bacterial inoculation by injection needle or the ink itself. Authors encountered a case of a 60-year-old man with a resectable sigmoid colon cancer which was tattooed with India ink for subsequent localization in the intraoperative setting. During the laparoscopic operation, the proximal and distal margin of the lesion appeared edematous with bluish color. The distal resection margin was extended approximately 5 cm more than expected because of long extent of edematous mucosa. Histologic examination of the edematous tattooing area revealed an ink abscess spreading laterally above the muscularis propria. Although tattooing is widely used and relatively safe, the presented case indicates the risk of infection or inflammation by tattooing.

OBJECTIVETo investigate the effect of GORE-TEX Dual Mesh fixing into peritoneum in sigmoid-colostomy on the prevention of peristomal hernia.

METHODSSixty patients undergone sigmoid-colostomy from Jan. 2003 to Jan. 2005 in the first affiliated hospital of Sun Yat-sen University were selected and randomly divided into two groups. Patients received papillary sigmoid-colostomy through rectus abdominis and peritoneum in control group and GORE-TEX Dual Mesh fixing into peritoneum during sigmoid-colostomy in observation group. Complications and recurrence rate were recorded in follow-up period.

RESULTSPeristomal hernia occurred in eight patients (8/30) in control group (26.7%), while no hernia happened in observation group (0/30).

CONCLUSIONGORE-TEX Dual Mesh fixing into peritoneum in sigmoid-colostomy can prevent peristomal hernia.

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.

Following improvements in therapy for childhood malignancies, the striking increase in survival rate over the past 30 years has led to the increase risk of developing second malignant neoplasms (SMNs). We report a case of colorectal carcinoma as a SMN, following treatment for rhabdomyosarcoma. The patient was diagnosed with rhabdomyosarcoma of the urinary bladder at his age of three years, and developed adenocarcinoma in the colon 13 years later. Histologic examination of the surgical specimen revealed adenocarcinoma involving the rectosigmoid area with radiation colitis in its background. The tumor cells showed strong immunoreactivity for p53 protein, suggesting the role of irradiation and p53 mutation in carcinogenesis. This case emphasizes the need for dose observation in survivors of early childhood malignancies treated with radiation and multiagent chemotherapy.
