RESUMEN
AIM: Constipation is a common problem which increases in prevalence with age. Chronic constipation is complex and difficult to treat. Some patients will not respond to pharmacological therapy and therefore surgery may be considered. A systematic review of the literature was performed to determine the outcome of surgery. METHOD: Published papers were identified by a search of The Cochrane Library, MEDLINE, CINAHL and EMBASE. They were reviewed and the data were extracted. RESULTS: Forty-eight papers were identified, including 1443 patients. Eleven different procedures were described. There was inconsistency in reporting. In 65% of patients the mean frequency of defaecation increased from 1.1 to 19.7 evacuations per week. Where laxative usage was reported (971 patients), it was found that 88% of patients did not need them postoperatively. Early complications included ileus (0-16%), infection (0-13%) and anastomotic leakage (0-22%). Patient satisfaction and quality of life scores were high. Only 30% of studies included data on preoperative psychological assessment. CONCLUSION: Surgery improves constipation and is associated with a higher degree of patient satisfaction, but the quality of studies was very variable. Future controlled trials should examine the ideal therapeutic approach for different patient groups.

BACKGROUND AND STUDY AIMS: The optimal treatment of bleeding due to radiation proctitis is still controversial. Although argon plasma coagulation (APC) has been recently reported as an effective treatment, its efficacy in relation to disease severity is unknown. The study aims were to prospectively evaluate (i) the efficacy of APC in endoscopically mild and severe radiation proctitis, and (ii) the recurrence rate following successful treatment. PATIENTS AND METHODS: 56 patients (mean age 68.4 years) with radiation proctitis after radiotherapy for prostate cancer were studied. All presented with rectal bleeding, occurring a median 21.5 months after radiotherapy. Using an established scoring system, patients were classified into two groups, with mild or severe disease. We also examined the correlation between endoscopic severity and hemoglobin level as a more objective measure of bleeding activity. Success was defined either as cessation of bleeding or a significant reduction so that further treatment was not required. RESULTS: Proctitis was classified as mild in 27 patients (48%) and severe in 29 (52%). Endoscopically judged severity and hemoglobin level showed good correlation (R = 0.58). All patients with mild proctitis and 23/29 (79%) with severe disease were successfully treated (P < 0.05). During a follow-up of a mean of 17.9 months (range 6-33), 34/38 patients (89.5%) remained in clinical remission. Recurrence was higher in those using anticoagulant or aspirin (P = 0.02). CONCLUSIONS: APC is highly effective in all patients with mild radiation proctitis and in the majority of those with severe disease, providing long-lasting clinical remission.

Oral and/or intestinal mucositis is a severe complication of hematopoietic SCT. Keratinocyte growth factor (KGF) has proven activity in the prevention of oral mucositis. We examined the efficacy of KGF in the prevention of intestinal mucositis. From January 2006 until December 2007, 35 consecutive patients underwent autologous SCT (auto-SCT) in our institution. A total of 15 consecutive patients who underwent auto-SCT from March 2007 to December 2007 received KGF for the prevention of mucositis and were included in the study group A, whereas 20 consecutive patients treated from January 2006 to March 2007, were included in the historical control group B. Oral and intestinal mucositis were significantly less severe in group A (P=0.002 and P<0.001, respectively). These results were confirmed with the use of video-capsule endoscopy. Patients in group A had a significantly lower incidence of neutropenic fever (P=0.026). Severe intestinal mucositis was significantly associated with a higher incidence of documented infections too (P=0.019). KGF is effective in the prevention of intestinal mucositis in patients undergoing auto-SCT. Patients with severe intestinal mucositis run a higher risk to develop infections.
