Abstract
Introduction A mini-laparotomy for colorectal cancer (CRC) has been reported to shorten postoperative ileus (POI) and hospital stay. Interleukin-6 (IL-6) plays a role in intestinal tissue inflammation, leading to POI. This study investigated the effects of abdominal wounds and IL-6 levels on POI in patients having CRC surgery. Materials and methods Forty-three patients with CRC underwent bowel resection. Serum samples were collected preoperatively and at 2, 24, and 48 h after surgery for cytokine quantification by ELISA. Clinical data, including time from surgery to first passage of flatus and postoperative hospital stay, demographic and pathological data, and routine blood tests, were compared statistically with abdominal wound length and the postoperative increments of cytokines (designated as Δ). Results The length of the abdominal wound showed a significant correlation with clinical variables (length of operation time, time of first flatus passage, and length of postoperative hospital stay) and cytokine variables (IL-6(Δ2 h), IL-8(Δ2 h) and IL-10(Δ2 h). Linear regression analysis showed that the abdominal wound length significantly influenced the operation time, time of first flatus passage, and length of postoperative hospital stay (p < 0.001). The length of the abdominal wound showed a significant influence on the IL-6(Δ2 h) and IL-8(Δ2 h) (p < 0.001, respectively) but no influence on IL-10(Δ2 h). IL-6(Δ2 h), but not IL-8(Δ2 h), significantly influenced the time to first flatus passage and length of hospital stay (p = 0.007, p = 0.006, respectively). The mini-laparotomy approach (wound length <7 cm) led to significantly shortened operation time, time of first flatus passage, length of postoperative stay (p = 0.004, p = 0.003, p = 0.006, respectively) as well as reduced postoperative increment of IL-6(Δ2 h) (p = 0.015). The mini-laparotomy for anterior resection surgery significantly influenced operation time, time of first passage of flatus, length of postoperative stay, and IL-6(Δ2 h). Conclusion Our study is the first to report the complex interaction among the length of the abdominal wound, IL-6 serum level, recovery of the first passage of flatus, and postoperative hospital stay. These results suggest that smaller abdominal wounds and smaller postoperative IL-6 increments were associated with faster recovery of flatus passage and shorter hospital stays.

Abstract
Post-operative ileus (POI) is an inevitable consequence of major abdominal surgery, and may be prolonged in up to 30% of patients. Ileus is commonly presumed to result from paralysis of the GI tract, though there is little direct evidence to support this view. The aim of this review is to systematically search and critically review the literature investigating post-operative colonic electrical and mechanical activity. MEDLINE and Embase databases were systematically searched for articles investigating post-operative colonic motor or electrical activity in human patients. Nineteen original articles investigating post-operative colonic motor or electrical activity were identified. Most studies have used low-resolution techniques, with intermittent recordings of colonic motility. Numerous studies have shown that colonic electrical and motor activity does not cease routinely following surgery, but is of abnormal character for 3–6 days following laparotomy. One recent high-resolution manometry study identified hyperactive cyclic motor patterns occurring in the distal colon on the first post-operative day. Low-resolution studies have shown colonic slow waves are not inhibited by surgery, and are present even in the immediate post-operative period. Recovery of normal motility appears to occur in a proximal to distal direction and is temporally correlated with the clinical return of bowel function. No studies have investigated motility specifically in prolonged POI. Future studies should use high-resolution techniques to accurately characterise abnormalities in electrical and mechanical function underlying POI, and correlate these changes with clinical recovery of bowel function.

Abstract
BACKGROUND Recovery after colonic surgery is invariably delayed by disturbed gut motility. It is commonly assumed that colonic motility becomes quiescent after surgery, but this hypothesis has not been evaluated rigorously. This study quantified colonic motility through the early postoperative period using high-resolution colonic manometry. METHODS Fibre-optic colonic manometry was performed continuously before, during and after surgery in the left colon and rectum of patients undergoing right hemicolectomy, and in healthy controls. Motor events were characterized by pattern, frequency, direction, velocity, amplitude and distance propagated. RESULTS Eight patients undergoing hemicolectomy and nine healthy controls were included in the study. Colonic motility became markedly hyperactive in all operated patients, consistently dominated by cyclic motor patterns. Onset of cyclic motor patterns began to a minor extent before operation, occurring with increasing intensity nearer the time of surgery; the mean(s.d.) active duration was 12(7) per cent over 3 h before operation and 43(17) per cent within 1 h before surgery (P = 0.024); in fasted controls it was 2(4) per cent (P < 0·001). After surgery, cyclic motor patterns increased markedly in extent and intensity, becoming nearly continuous (active duration 94(13) per cent; P < 0·001), with peak frequency 2-4 cycles per min in the sigmoid colon. This postoperative cyclic pattern was substantially more prominent than in non-operative controls, including in the fed state (active duration 27(20) per cent; P < 0·001), and also showed higher antegrade velocity (P < 0·001). CONCLUSION Distal gut motility becomes markedly hyperactive with colonic surgery, dominated by cyclic motor patterns. This hyperactivity likely represents a novel pathophysiological aspect of the surgical stress response. Hyperactive motility may contribute to gut dysfunction after surgery, potentially offering a new therapeutic target to enhance recovery.

Abstract
Abstract
Background
Colorectal resections alter colonic motility, including disruption of control by neural or bioelectrical cell networks. The long-term impact of surgical resections and anastomoses on colonic motor patterns has, however, never been assessed accurately. Fibreoptic high-resolution colonic manometry was employed to define motility in patients who had undergone distal colorectal resection.
Methods
Recruited patients had undergone distal colorectal resections more than 12 months previously, and had normal bowel function. Manometry was performed in the distal colon (36 sensors; 1-cm intervals), with 2-h recordings taken before and after a meal, with comparison to controls. Analysis quantified all propagating events and frequencies (cyclical, short single, and long single motor patterns), including across anastomoses.
Results
Fifteen patients and 12 controls were recruited into the study. Coordinated propagating events directly traversed the healed anastomoses in nine of 12 patients with available data, including antegrade and retrograde cyclical, short single and long single patterns. Dominant frequencies in the distal colon were similar in patients and controls (2–3 cycles/min) (antegrade P = 0·482; retrograde P = 0·178). Compared with values before the meal, the mean(s.d.) number of dominant cyclical retrograde motor patterns increased in patients after the meal (2·1(2·7) versus 32·6(31·8) in 2 h respectively; P < 0·001), similar to controls (P = 0·178), although the extent of propagation was 41 per cent shorter in patients, by a mean of 3·4 cm (P = 0·003). Short and long single propagating motor patterns were comparable between groups in terms of frequency, velocity, extent and amplitude.
Conclusion
Motility patterns and meal responses are restored after distal colorectal resection in patients with normal bowel function. Coordinated propagation across healed anastomoses may indicate regeneration of underlying cellular networks.

Abstract
Postoperative ileus (POI) is an abnormal pattern of gastrointestinal motility characterized by nausea, vomiting, abdominal distension and/or delayed passage of flatus or stool, which may occur following surgery. Postoperative ileus slows recovery, increases the risk of developing postoperative complications and confers a significant financial load on healthcare institutions. The aim of the present review is to provide a succinct overview of the clinical features and pathophysiological mechanisms of POI, with final comment on selected directions for future research.Terminology used when describing POI is inconsistent, with little differentiation made between the obligatory period of gut dysfunction seen after surgery ('normal POI') and the more clinically and pathologically significant entity of a 'prolonged POI'. Both normal and prolonged POI represent a fundamentally similar pathophysiological phenomenon. The aetiology of POI is postulated to be multifactorial, with principal mediators being inflammatory cell activation, autonomic dysfunction (both primarily and as part of the surgical stress response), agonism at gut opioid receptors, modulation of gastrointestinal hormone activity and electrolyte derangements. A final common pathway for these effectors is impaired contractility and motility and gut wall oedema. There are many potential directions for future research. In particular, there remains scope to accurately characterize the gastrointestinal dysfunction that underscores an ileus, development of an accurate risk stratification tool will facilitate early implementation of preventive measures and clinical appraisal of novel therapeutic strategies that target individual pathways in the pathogenesis of ileus warrant further investigation.

Abstract
PURPOSE Published studies comparing the addition of chewing gum to standardized postoperative care to shorten postoperative ileus showed controversial results. This study was designed to conduct a systematic review of all relevant trials on chewing gum to reduce postoperative ileus after colorectal resection. METHODS All published trials that compared the additional use of gum chewing with standard postoperative management were identified from Ovid MEDLINE, EMBASE, CINAHL, and All Evidence-Based Medicine Reviews between January 1991 and January 2007. The clinical outcomes were extracted and meta-analysis was performed by Forest plot review. RESULTS Five randomized, controlled trials with 158 (94 males) patients with mean age of 61.9 years were included. Seventy-eight patients received an addition of gum chewing and 80 had standard postoperative care for colorectal resection. Operating time (P = 0.78) and blood loss (P = 0.48) were similar. All patients tolerated the gum without any side-effects. With combined standard postoperative care and gum chewing, the patients passed flatus 24.3 percent earlier (weighted mean difference, -20.8 hours; P = 0.0006) and had bowel movement 32.7 percent earlier (weighted mean difference, -33.3 hours; P = 0.0002). They were discharged 17.6 percent earlier than those having ordinary postoperative treatment (weighted mean difference, -2.4 days; P < 0.00001). The gum-chewing group was associated with similar overall postoperative complication rate (odds ratio, 0.45; P = 0.05) with individual complication showing a trend favoring gum chewing, although they were not of statistical significance. Readmission (odds ratio, 0.36; P = 0.24) and reoperation rates (odds ratio, 1.36; P = 0.83) of the two groups were similar. CONCLUSIONS The use of gum chewing in the postoperative period is a safe method to stimulate bowel motility and reduce ileus after colorectal surgery.

Abstract
Nausea and vomiting following surgery may either occur as postoperative nausea and vomiting, which is a condition that is mainly related to anesthesia, or as secondary to postoperative ileus, which denotes inhibition of gastrointestinal motility following surgery. Postoperative ileus is a multifactorial event with several contributing mechanisms. Although postoperative nausea and vomiting pathophysiology has been quite well-studied little is known about it. There are multiple targets for treatment, prevention, and its successful empirical management e.g. by 5-HT(3) receptor antagonists. This review describes different aspects of the pathophysiology of postoperative ileus and postoperative nausea and vomiting, their relevance to postoperative care, and the standardized approach to manage postoperative nausea and vomiting that was established by Apfel and coworkers. Despite the recent advances in the understanding and treatment of conditions that trigger nausea and vomiting in the postoperative period, these symptoms remain a significant problem that affects patients' recovery, comfort, and treatment cost.

Abstract
OBJECTIVE Postoperative ileus is common after colorectal resection and can prolong hospital stay. Gum chewing, a type of sham feeding, may to stimulate gut motility via cephalic-vagal stimulation, and thereby reduce the length of ileus. This study aimed to determine whether gum chewing in the immediate postoperative period facilitated recovery from ileus following resection for left-sided colorectal cancer. METHODS In a prospective randomized control trial, 38 patients undergoing open surgery for left-sided colorectal cancer were allocated to standard postoperative care (control group, n = 19) or to standard postoperative care plus the immediate use of chewing gum (treatment group, n = 19). RESULT Control patients passed flatus by mean of 2.7 days (SD 1.0) and faeces by 3.9 days (SD 1.5); for the treatment group, this was 2.4 days (SD 1.0) and 3.2 days (SD 1.5) respectively, (NS, P = 0.56 and P = 0.38). Length of hospital stay was 11.1 days (SD 7.3) in control group and 9.4 days (SD 2.5) in the treatment group (NS, P = 0.75). CONCLUSION The addition of gum chewing to a standardized postoperative regimen did not reduce the period of postoperative ileus or shorten length of stay following open surgery for left-sided colorectal cancer.

Abstract
BACKGROUND Stimulation of colonic motility by the gastrocolonic response may help to reduce inhibition of gastrointestinal motility after colorectal surgery. We aimed to investigate whether postoperative colonic motility is increased after early food intake. METHODS Nineteen patients undergoing colorectal surgery and 7 healthy volunteers were investigated. Colonic motility was recorded with a combined manometry/barostat system, and the effect of a standard 500-kcal meal was evaluated once in healthy volunteers and in 15 patients on the first and second postoperative day. Four patients remained unfed, serving as controls. RESULTS In patients, the colonic motility index increased from 12 +/- 5 at baseline to 65 +/- 24 mm Hg after the meal on postoperative day 1 (mean +/- SEM; P < .01), while barostat bag volumes decreased, indicating a rise in colonic tone. On day 2, the motility index was 62 +/- 17 mm Hg at baseline and did not change after the meal. In unfed controls, no change was observed during colonic motility recordings on both postoperative days. In healthy volunteers, the colonic motility index increased from 98 +/- 52 at baseline to 151 +/- 58 mm Hg postprandially (P < .05). CONCLUSIONS As in healthy volunteers, there is a potential to stimulate colonic motility by early food intake in postoperative patients. This may help to improve prolonged colonic motility disorders after colorectal surgery.

Abstract
OBJECTIVE To investigate local inflammatory events within the colonic muscularis as a causative factor of postoperative ileus. SUMMARY BACKGROUND DATA Surgically induced intestinal muscularis inflammation has been hypothesized as a mechanism for postoperative ileus. The colon is a crucial component for recovery of gastrointestinal motor function after surgery but remains unaddressed. The authors hypothesize that colonic manipulation initiates inflammatory events that directly mediate postoperative smooth muscle dysfunction. METHODS Rats underwent colonic manipulation. In vivo transit and colonic motility was estimated using geometric center analysis and intraluminal pressure monitoring. Leukocyte extravasation was investigated in muscularis whole mounts. Mediator mRNA expression was determined by real-time reverse transcriptase-polymerase chain reaction. In vitro circular muscle contractility was assessed in a standard organ bath. The relevance of iNOS and COX-2 inhibition was determined using DFU or L-NIL perfusion. RESULTS Colonic manipulation resulted in a massive leukocyte recruitment and an increase in inflammatory mRNA expression. This inflammatory response was associated with an impairment of in vivo motor function and an inhibition of in vitro smooth muscle contractility (56%). L-NIL but not DFU significantly ameliorated smooth muscle dysfunction. CONCLUSIONS The results provide evidence for a surgically initiated local inflammatory cascade within the colonic muscularis that mediates smooth muscle dysfunction, which contributes to postoperative ileus.

Abstract
BACKGROUND Gastrointestinal motility is frequently impaired after abdominal surgery. We investigated the effects of neostigmine on colonic motility in patients after colorectal surgery and in healthy volunteers. METHODS Colonic motility was recorded by a manometry/barostat system in 12 patients after left colonic or rectal resection during baseline and after the intravenous administration of increasing doses of neostigmine on postoperative days 1, 2, and 3. In addition, colonic motility was recorded in 7 healthy volunteers. RESULTS Neostigmine increased the colonic motility index. This increase was from 135 +/- 28 mm Hg/min at baseline to 574 +/- 219 mm Hg/min after administration of 5 microg/kg neostigmine on day 3 after surgery (mean +/- SEM, P <.05). In healthy volunteers, neostigmine at a dose of 5 microg/kg increased the colonic motility index from 184 +/- 73 to 446 +/- 114 mm Hg/min (P <.05). Barostat bag volumes decreased dose-dependently after neostigmine administration in patients as well as in volunteers, indicating an increase in colonic tone. CONCLUSIONS Colonic motility and tone increased after neostigmine administration at a dose of 5 microg/kg in postoperative patients and in healthy volunteers. Neostigmine can be used to stimulate colonic motility after colorectal surgery and has a similar effect postoperatively as in healthy volunteers.

Abstract
BACKGROUND Postoperative ileus has traditionally been accepted as a normal response to tissue injury. No data support any beneficial effect of ileus and indeed it may contribute to delayed recovery and prolonged hospital stay. Efforts should, therefore, be made to reduce such ileus. METHODS Material was identified from a Medline search of the literature, previous review articles and references cited in original papers. This paper updates knowledge on the pathophysiology and treatment of postoperative ileus. RESULTS AND CONCLUSION Pathogenesis mainly involves inhibitory neural reflexes and inflammatory mediators released from the site of injury. The most effective method of reducing ileus is thoracic epidural blockade with local anaesthetic. Opioid-sparing analgesic techniques and non-steroidal anti-inflammatory agents also reduce ileus, as does laparoscopic surgery. Of the prokinetic agents only cisapride is proven beneficial; the effect of early enteral feeding remains unclear. However, postoperative ileus may be greatly reduced when all of the above are combined in a multimodal rehabilitation strategy.

Abstract
PURPOSE Colonic motility is crucial for the resolution of postoperative ileus. However, few data are available on postoperative colonic motility and no data on postoperative colonic tone. We aimed to characterize postoperative colonic tone and motility in patients. METHODS Nineteen patients were investigated with combined barostat and manometry recordings after left colonic surgery. During surgery a combined recording catheter was placed in the colon with two barostat bags and four manometry channels cephalad to the anastomosis. Recordings were performed twice daily from Day 1 to Day 3 after surgery. RESULTS Manometry showed an increasing colonic motility index, which was a mean (+/- standard error of the mean) of 37 +/- 5 mmHg/minute on Day 1, 87 +/- 19 mmHg/minute on Day 2, and 102 +/- 13 mmHg/minute on Day 3 (P < 0.05 for Day 1 vs. Day 2 and Day 2 vs. Day 3). Low barostat bag volumes indicating a high colonic tone were observed on Day 1 after surgery and increased subsequently (barostat bag I was 19 +/- 4, 32 +/- 6, and 32 +/- 6 ml; barostat bag II was 13 +/- 1, 19 +/- 3, and 22 +/- 5 ml on Days 1, 2, and 3, respectively; for both barostat bags P < 0.05 for Day 1 vs. Day 2 but not Day 2 vs. Day 3). CONCLUSIONS Colonic motility increased during the postoperative course. The low barostat bag volumes indicated a high colonic tone postoperatively which would correspond to a contracted rather than to a distended colon. High colonic tone postoperatively may be relevant for pharmacologic treatment of postoperative ileus.

Abstract
PURPOSE This study was designed to investigate the modulatory effect of cisapride on colonic motility in the postoperative period. METHODS A prospective, double-blind, randomized, placebo-controlled trial of 14 patients undergoing left colonic anastomosis was carried out. Manometric probes were positioned with transducers on either side of the anastomosis, and colonic activity was recorded continuously for a median of 98 (range, 72-144) hours using an ambulatory system. Quantitative indices of motility were calculated with an automated analysis program. RESULTS Isolated waveform activity returned at a median of 1.8 (interquartile range, 1-3) hours and motor complex activity at 24 (interquartile range, 19-30) hours in the placebo group and at similar times in the cisapride group. All motility variables except mean amplitude increased significantly with time in both groups. In the cisapride group the motility index was significantly increased compared with the placebo group (P = 0.03), resulting from an increase in percentage duration of activity (P = 0.002). Activity index, mean amplitude of waveforms, and number of waves greater than 50 cm H2O did not differ between groups. In contrast to placebo, cisapride significantly increased the median number of waves greater than 13 cm H2O and percentage duration of activity distal to the anastomosis compared with proximally. The return of bowel sounds (median, 43, interquartile range, 24-48 hours vs. 67, 29-69 hours; P = 0.2) or first passage of flatus (78, 54-94 hours vs. 94, 81-105 hours; P = 0.1) did not differ between groups. CONCLUSIONS Although cisapride may have a differential effect on the colon proximal and distal to an anastomosis and significantly increases some indices of motility in the early postoperative period, these are unlikely to be of any clinical relevance.
