    Abstract Background: The aim of the study was to evaluate the clinical usefulness of anorectal manometry (AM) in patients affected by obstructed defecation (OD).
    Methods: Between January 2007 and December 2010, 379 patients (287 women and 92 men) affected by OD were evaluated. After a preliminary clinical evaluation, defecography and AM were performed. The results were compared with those from 20 healthy control subjects.
    Results: Overall anal resting pressure was not significantly different between patients and controls. Maximal voluntary contraction (MVC) data were significantly lower when compared with those of controls (P < 0.01). The straining test was considered positive in 143 patients. No significant difference was noted between patients and controls in maximal tolerated volume data. Patients had a significantly higher conscious rectal sensitivity threshold than controls (P < 0.02).
    Conclusions: A positive straining test, low MVC and impaired rectal sensation are the main abnormalities detected by AM in patients with OD.

    Abstract Aim: The study was designed to evaluate the results of rehabilitative treatment in patients suffering from obstructed defaecation.
    Method: Between January 2008 and July 2010, 39 patients (37 women, age range 25-73 years; and two men, aged 57 and 67 years) affected by obstructed defaecation were included in the study. After a preliminary clinical evaluation, including the Obstructed Defaecation Syndrome (ODS) score, defaecography and anorectal manometry were performed. All 39 patients underwent rehabilitative treatment according to the 'multimodal rehabilitative programme' for obstructive defaecation. At the end of the programme, all 39 patients were reassessed by clinical evaluation and anorectal manometry. Postrehabilition ODS scores were used to categorize patients arbitrarily into three classes, as follows: class I, good (score ≤ 4); class II, fair (score > 4 to ≤ 8); and class III, poor (score > 8).
    Results: After rehabilitation, there was significant improvement in the overall mean ODS score (P < 0.001). Thirty (76.9%) patients were included as class I (good results), of whom eight (20.5%) were symptom free. Five (12.8%) patients were considered class III. A significant postrehabilitative direct correlation was found between ODS score and pelvic surgery (ρ(s) = 0.54; P < 0.05). Significant differences were found between pre- and postrehabilitative manometric data from the straining test (P < 0.001), duration of maximal voluntary contraction (P < 0.001) and conscious rectal sensitivity threshold (P < 0.02).
    Conclusion: After rehabilitation, some patients become symptom free and many had an improved ODS score.

    Abstract Background: The motility of the defunctionalized colon, distal to transverse loop colostomy, has never been studied "in vivo." The aim of our study was to evaluate the influence of transverse loop colostomy on colonic motility.
    Methods: Thirteen patients were examined before stoma closure by means of clinical evaluation and colonic manometry; we studied both the right and distal colon in both fasting and fed patients in order to detect motor activity.
    Results: Quantitative and qualitative manometric analyses showed that the diverted colon had motor activity even if no regular colonic motor pattern was observed. The spreading of aboral propagated contractions (PCs) was sometimes recorded from the right colon to the distal colon. The response of the proximal and distal colon to a standard meal, when compared to fasting values, increased more than 40 and 35 %, respectively. Stool and gas ejections from the colostomy were never related to a particular type of colonic motility: Motor quiescence such as PCs was chaotically related to stool escape.
    Conclusions: In conclusion, motility of the defunctionalized colon is preserved in patients with transverse loop colostomy.

    Abstract Background: Rehabilitation is the first therapeutic step of obstructed defecation, after failure of conservative therapy with high-fiber diet and laxatives. This study evaluates the usefulness of psyllium, a bulk-forming agent, when used during rehabilitation of obstructed defecation.
    Methods: Between January 2008 and December 2010, 45 patients affected by obstructed defecation were included in the study. Two randomized groups were selected. Group 1 (21 women; age range 25-67 (mean, 51.8) years) continued to consume a high-fiber diet (approximately 30 g fiber per day) during rehabilitation. Group 2 (24 women; age range 46-71 (mean, 59.8) years) consumed only psyllium (3.6 g × 2/day; Psyllogel(®) Fibra, Nathura, Montecchio Emilia, Italy) during the rehabilitative cycle. After a preliminary clinical evaluation, including the obstructed defecation syndrome (ODS) score, patients underwent defecography and anorectal manometry as well as rehabilitative treatment according to the "multimodal rehabilitative program" for obstructive defecation. At the end of the program, patients were reassessed by clinical evaluation and anorectal manometry. Post-rehabilitative ODS scores were used for an arbitrary schedule of patients divided into three classes: Class I, good (score ≤ 4); Class II, fair (score > 4 to ≤ 8); Class III, poor (score > 8).
    Results: The number of bowel movements per week did not increase significantly after rehabilitation. Both groups had a significantly better Bristol stool form scale score (Group 1: P < 0.034; Group 2: P < 0.02). The overall mean ODS score from Groups 1 and 2 showed significant improvement after treatment (P < 0.001). Twenty-eight patients (82.3%) were Class I (good results) without significant differences between groups. Nine women were symptom-free. Significant differences were found between pre-rehabilitative and post-rehabilitative manometric data from the straining test (P < 0.001) and duration of maximal voluntary contraction (Group 1: P < 0.004; Group 2: P < 0.02). A significant difference was found between the pre-rehabilitative and post-rehabilitative conscious rectal sensitivity threshold (CRST) in Group 2 women (P < 0.02). The Group 2 women who underwent volumetric rehabilitation (11 patients) had significantly lower post-rehabilitative CRST values than pre-rehabilitative values (P < 0.002); the length of volumetric rehabilitation was also significantly shorter in Group 2 patients (P < 0.04) than in Group 1 patients.
    Conclusions: After rehabilitation of obstructed defecation, some patients became symptom-free and many had an improved ODS score. Psyllium is helpful for volumetric rehabilitation: patients who consumed psyllium had lower post-rehabilitative CRST values than subjects were on high-fiber diet.

    Abstract Pathological stage seems to be the major determinant of postoperative prognosis of solid tumors, but additional prognostic determinants need to be better investigated. The most important tumor marker for colorectal cancer (CRC) is the cell-surface antigen, Carcinoembryonic Antigen (CEA), and its assessment is considered a valuable index of circulating tumor cells (CTCs). In this paper, CEACAM3 evaluation was applied given its great specificity in the CRC. Whole blood from the basilic vein of 38 CRC patients was collected before and at various time intervals after the curative resection. Also, from 20 of them, we have obtained two additional intraoperative samples. CEACAM3 expression was evaluated in all the samples by RT-PCR. CEACAM3 duct values showed a decreasing trend from preoperative through early and later postoperative to 6th-month samples (p < 0.001). The average values of CEACAM3 were related to the cancer size (T stage) (p = 0.034) and WHO stage (p = 0.035). A significant effect of the baseline value of CEACAM3 dCt on the temporal trend has been observed (p < 0.001). In this study, we have demonstrated the CEACAM3 specificity and a perioperative trend of CTCs which is coherent with the clinical/pathological considerations and with previous experimental findings in different cancer types.

    Abstract Background: The present aim was to study the modulation of NK2 receptor internalization by two compounds, the spasmolytic otilonium bromide (OB) endowed with NK2 receptor antagonistic properties and the selective NK2 receptor antagonist ibodutant.
    Methods: Full-thickness human colonic segments were incubated in the presence of OB (0.1-10 μmol L(-1)) or ibodutant (0.001-0.1 μmol L(-1)), with or without the NK2 receptor selective agonist [ßAla8]NKA(4-10) and then fixed in 4% paraformaldehyde. Cryosections were processed for NK2 receptor immunohistochemical revelation. Quantitative analysis evaluated the number of the smooth muscle cells that had internalized the NK2 receptor.
    Key results: Immunohistochemistry revealed that in basal condition, the NK2 receptor was internalized in about 23% of total smooth muscle cells. The exposure to the selective NK2 receptor agonist induced internalization of the receptor in more than 77% of the cells. Previous exposure to both OB or ibodutant, either alone or in the presence of the agonist, concentration-dependently reduced the number of the cells with the internalized receptor.
    Conclusions & inferences: Both OB and ibodutant antagonize the internalization of the NK2 receptor in the human colon. As NK2 receptors are the predominant receptor mediating spasmogenic activity of tachykinins on enteric smooth muscle, we hypothesize that the antagonistic activity found for both OB and ibodutant should play a specific therapeutic role in gut diseases characterized by hypermotility.
