Kawasaki disease (KD) is recognized as a systemic vasculitis affecting multi-organ with inflammatory changes. The commonest and most serious complication of KD is coronary artery aneurysm, but KD may cause other organic complications beside cardiac problems. Gastrointestinal tract also present complications of KD in which, for example, hepatic dysfunction, pancreatitis, intussusception, colonic obstruction, intestinal pseudo-obstruction, and bowel edema are included. Among them, colonal wall edema is left unknown in the incidence, and it has been reported even if rare. In this report, we describe a case of KD with colonal wall edema, occurred in 5-yr-old boy who complained of severe abdominal pain and vomiting.

One case of pneumoscrotum associated with spontaneous colon perforation was reported. The patient was a 66-year-old man, presented with high temperature, mild abdominal pain and an enlarged scrotum. Physical examination revealed scrotal swelling, abdominal tenderness Case Report and muscular defense. Computed tomography (CT) of the abdomen showed swelling and pneumatosis of the left major psoas and iliopsoas muscles, and ultrasound found subcutaneous emphysema of the scrotum. Surgical investigation discovered a retroperitoneal perforation in the descending colon connected with a huge retroperitoneal vomica and scrotal sac. Spontaneous colon perforation induced pneumoscrotum is rare clinically. It may present as colon perforation, which calls for special attention.

Rupture of the colon caused by high pressure compressed air is a rare, unique and traumatic intra-abdominal injury. As the use of compressed air in industrial work has increased, so has the risk of associated pneumatic injuries from its improper use. Recently we experienced a case of pneumatic rupture of the sigmoid colon accompanied by tension pneumoperitoneum, which caused respiratory distress. The patient's respiration was very rapid with the rate of 44 breaths per minute. On arterial blood gas analysis, pH was 7.40, pO2 68 mmHg, pCO2 44 mmHg, and SaO2 90%. Chest X-ray film showed marked pneumoperitoneum and an elevated diaphragm. The respiratory distress was severe and required immediate relief by emergency decompression peritoneocentesis before surgical intervention consisting of the serosal tear repair, colonic rupture colostomy and abdominal cavity irrigation. A follow up operation 2 months later for colostomy repair completed the patient's recovery.

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.

A 36-year-old woman presented with a palpable tender mass at the left lower quadrant of the abdomen. She had suffered from constipation for five years and had a previous history of intrauterine device-use for one year. Preoperative barium enema and abdominopelvic CT showed a compatible finding of rectosigmoid colon cancer or left ovary cancer. She underwent segmental resection of the sigmoid colon along with the removal of left distal ureter, left ovary and salpinx. Pathologic examination revealed actinomycotic abscesses containing sulfur granules. Thereafter, she took parenteral ampicillin (50mg/kg/day) for one month and oral amoxicillin (250mg, tid) for 2 months consecutively. The patient has no specific problems for 6 months after surgical resection and long-term antibiotic therapy. This report may be the first of intrauterine device-associated pelvic actinomycosis involving both sigmoid colon and rectum extensively.

BACKGROUNDThe relationship between melanosis coli (MC) and aquaporin 8 (AQP8) has not yet been elucidated. The aim of this research was to investigate the relationship between the expression of AQP8 and the pathological mechanism of MC.

METHODSExpression of AQP8 was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR) in 37 MC colon tissues and 13 control colon tissues. Global gene expression analysis was also used to identify differently expressed genes. Its relationship with MC was analyzed by SPSS 11.5 statistical software.

RESULTSThe positive rate of AQP8 expression detected by immunohistochemistry in the MC group was 24.3% (9/37), significantly lower than the 69.2% (9/13) in the control group (P < 0.05). The relative expression level of AQP8 in MC group was 0.639 ± 0.160, lower than 0.921 ± 0.148 of controls (P < 0.05). Global gene expression analysis showed that AQP8 mRNA expression was downregulated in MC patients.

CONCLUSIONSThe decreased AQP8 expression in MC patients indicates that chronic use of laxatives containing anthraquinone may cause reduced water absorption. The expression of AQP8 may be related to MC.

The association between rectosigmoid polyps and polyps in the more proximal colon is still a matter of debate, and the need for colonoscopy in patients with rectosigmoid polyps that are detected by flexible sigmoidoscopy is controversial. The aim of this study was to determine whether or not certain characteristics of rectosigmoid polyps are associated with the presence and characteristics of proximal colonic polyps. Seven hundred and twenty-eight patients who underwent total colonoscopy between October 1995 and June 1998 and who had colorectal polyps were retrospectively analyzed. Patients with inflammatory bowel diseases, familial adenomatous polyposis, or any advanced cancer were excluded. The odds ratio (OR) and 95% confidence interval (CI) of prevalence of proximal colonic polyps according to the patients age and sex, as well as the characteristics of rectosigmoid polyps, were calculated. Advanced adenoma was defined as an adenoma larger than 10 mm or an adenoma of any size with villous component, high-grade dysplasia or invasive carcinoma. Among 728 patients with colorectal polyps, 356 patients (48.9%) had polyps only in the rectosigmoid region, 193 patients (26.5%) had polyps only in the proximal colon, and 179 patients (24.6%) had polyps in both the rectosigmoid and proximal colon. In 535 patients with rectosigmoid polyps, the prevalence of proximal colonic polyps, neoplastic polyps and advanced adenomas were 33.4%, 27.3% and 2.9%, respectively. The prevalence of proximal colonic polyps in patients with rectosigmoid polyps was found to be significantly related to the male gender and elderly patients, in addition to the neoplastic histology of the rectosigmoid polyps. However, the prevalence of the proximal colonic polyps was not related to the size, number and shape of rectosigmoid polyps. In 179 patients with both rectosigmoid and proximal colonic polyps, the characteristics of proximal colonic polyps such as size, number and shape were similar to those of rectosigmoid polyps. We recommend total colonoscopic examination in all patients with rectosigmoid adenomas, regardless of the size, number, and shape, especially in elderly males.
