OBJECTIVETo discuss the value of multi-slice CT dynamic enhancement scan in the diagnosis and treatment of colonic lymphomas.

METHODS16 patients with colonic lymphomas underwent multi-slice CT dynamic enhancement scans, images of axial and reconstructive images of VR, MPR and CTVE were analyzed, patients were respectively diagnosed.

RESULTSAppearances of primary colorectal lymphomas were categorized into focal and diffuse lesions. Focal and diffuse lesions were 6 and 10 patients, respectively. The accuracy rate of diagnosis was 87.5%.

CONCLUSIONMSCT dynamic scan has distinctive superiority in diagnosis and treatment of colonic lymphomas.

OBJECTIVETo investigate the effects of fibrin glue and growth hormone on the healing of colon anastomoses after immediate postoperative intraperitoneal chemotherapy.

METHODSForty-eight rats were randomly divided into 4 groups, and received colon resection and anastomosis(control group),or early postoperative intraperitoneal chemotherapy(EPIC) with 5-Fu(20 mg*d kg-1*d-1) for 3 days after operation (chemotherapy group), or coverage of the stoma with fibrin glue and then EPIC(FG group), coverage of the stoma with fibrin glue and then EPIC plus subcutaneous injection of growth hormone(1 mg*d kg-1*d-1)(GH group). All the rats were killed on the 8th postoperative day, and adhesion formation score, bursting pressure of the stoma, and histological score were investigated.

RESULTSThe adhesion formation score in chemotherapy group was significantly higher than those in the other three groups(P< 0.05); but there was no significant difference among the other three groups(P > 0.05). The bursting pressure of the stoma was significantly higher in GH group than those in the other three groups; and significantly higher in FG group and the control group than that in chemotherapy group. The histological score of the stoma in GH group was significantly higher than those in the other three groups(P< 0.05).

CONCLUSIONFibrin glue in combination with growth hormone can enhance the strength of the stoma and improve the healing of colon anastomoses in the condition of early postoperative intraperitoneal chemotherapy.

PURPOSE: Postoperative ileus (POI) is an impairment of coordinated gastrointestinal (GI) motility that develops as a consequence of abdominal surgery and is a major factor contributing to patient morbidity and prolonged hospitalization. The aim of this study was to investigate the effects of different 5-hydroxytryptamine 4 (5-HT4) receptor agonists, which stimulate excitatory pathways, on a POI model. MATERIALS AND METHODS: The experimental model of POI in guinea pigs was created by laparotomy, gentle manipulation of the cecum for 60 seconds, and closure by suture, all under anesthesia. Different degrees of restoration of GI transit were measured by the migration of charcoal. Colonic transit was indirectly assessed via measurement of fecal pellet output every hour for 5 hours after administration of various doses of mosapride, tegaserod, prucalopride, and 5-HT. RESULTS: Charcoal transit assay showed that various 5-HT4 receptor agonists can accelerate delayed upper GI transit in a dose-dependent manner. However, fecal pellet output assay suggested that only prucalopride had a significant effect in accelerating colonic motility in POI. CONCLUSION: Although mosapride, tegaserod, and prucalopride produce beneficial effects to hasten upper GI transit in the POI model, prucalopride administered orally restores lower GI transit as well as upper GI transit after operation in a conscious guinea pig. This drug may serve as a useful candidate for examination in a clinical trial for POI.

BACKGROUND/AIMS: We investigated whether sodium picosulfate with magnesium citrate (SPMC) plus bisacodyl compares favorably with conventional polyethylene glycol (PEG) with respect to bowel cleansing adequacy, compliance, and safety. METHODS: We performed a multicenter, prospective, single-blinded study in outpatients undergoing daytime colonoscopies. Patients were randomized into a split preparation SPMC/bisacodyl group and a conventional split PEG group. We compared preparation adequacy using the Boston bowel preparation scale (BBPS), ease of use using a modified Likert scale (LS), compliance/satisfaction level using a visual analogue scale (VAS), and safety by monitoring adverse events during the colonoscopy between the two groups. RESULTS: A total of 365 patients were evaluated by intention to treat (ITT) analysis, and 319 were evaluated by per protocol (PP) population analysis (153 for SPMC/bisacodyl, 166 for PEG). The mean total BBPS score was not different between the two groups in both the ITT and PP analyses (p>0.05). The mean VAS score for satisfaction and LS score for the ease of use were higher in the SPMC/bisacodyl group (p<0.001). The adverse event rate was lower in the SPMC/bisacodyl group than in the PEG group (p<0.05). CONCLUSIONS: The SPMC/bisacodyl treatment was comparable to conventional PEG with respect to bowel preparation adequacy and superior with respect to compliance, satisfaction, and safety.
