Abstract
BACKGROUND The authors present a modified surgical technique during tumor nephrectomy in children with a conservative approach towards small bowel manipulation and cutting of the peritoneal reflections. We aimed to evaluate this modified surgical approach regarding the incidence of post-operative small bowel obstruction (SBO), and its technical utility. METHODS The study includes all children with unilateral renal tumors who underwent radical nephrectomy and lymph nodes sampling at our tertiary center from 2010 to 2022. The modified technique was performed via the usual transverse incision. We cut the peritoneal reflections short of the cecum or short of the sigmoid colon. The colon is reflected over SB packing it, proceeding to nephrectomy and lymph nodes sampling. Data included demographics, clinical characteristics, treatment strategy, operative details, post-operative SBO, and overall outcomes. RESULTS The study included 890 patients with a median age of 3.2 years. The median tumor largest diameter was 13 cm (range: 9-18 cm). The modified surgical technique was adopted in 287 patients (32.3 %). Forty-three patients (43/890, 4.8 %) had post-operative SBO. Out of them, only 4 cases were operated on using the modified surgical technique (p-value<0.001). There were no significant differences between both techniques regarding timing of surgery, tumor rupture, lymph nodes sampling, and tumor size (p-value = 0.775, 0.328, 0.216, and 0.563, respectively). CONCLUSIONS The modified surgical approach is significantly correlated with lower incidence of post-operative SBO with no increased risk of tumor rupture or incomplete lymph nodes sampling. The timing of surgery or tumor characteristics had no significant impact on the technical utility of the modified surgical approach. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Laparoscopic surgery (LS) is reported to reduce postoperative complications and hospital stay compared with open surgery (OP). Because patient selection may have been biased in previous studies, propensity score matching (PSM) analysis was used in this study to test the benefits of LS compared with OP. METHODS A total of 759 patients with stage I-III colorectal cancer undergoing curative surgery were retrospectively reviewed. To minimize confounding bias between LS and OP groups, a 1:1 PSM analysis was performed based on adjuvant chemotherapy, age, albumin, body mass index, American Society of Anesthesiologists physical status depth of tumor, gender, lymph node dissection, maximum tumor size, obstructive tumor, previous abdominal surgery, pathological stage, tumor differentiation, and tumor location. Statistical analyses including chi-square test, Mann-Whitney U test, univariate analyses and Kaplan-Meier method and log-rank test were performed using the data after PSM to investigate the benefits of LS compared with OP. RESULTS After PSM analysis, 460 patients remained in the study. The LS group had lower intraoperative blood loss (34 ± 70 vs 237 ± 391, mL; P < 0.001), lower frequency of postoperative small bowel obstruction (SBO) (17/213 vs 30/230; P = 0.045), lower rate of nasogastric tube insertion (7/223 vs 17/213; P = 0.036), and shorter postoperative hospital stay (13 ± 10 vs 25 ± 47, day; P < 0.001) than the OP group. Univariate analyses showed that LS significantly reduced the risk of postoperative SBO (odds ratio [OR] 0.532; 95% confidence interval [CI] 0.285-0.995; P = 0.048) and nasogastric tube insertion (OR 0.393; 95% CI 0.160-0.967; P = 0.042) compared with OP. There were no significant differences in OS and RFS between the groups. CONCLUSIONS LS reduced intraoperative blood loss, frequency of postoperative SBO, rate of nasogastric tube insertion, and postoperative hospital stay compared with OP.

Abstract
BACKGROUND Cystic fibrosis (CF) is the most common, life-limiting, genetically inherited disease. It affects multiple organs, particularly the respiratory system. However, gastrointestinal problems such as constipation and distal intestinal obstruction syndrome (DIOS) are also important and well-recognised complications in CF. They share similar symptoms e.g. bloating, abdominal pain, but are distinct conditions. Constipation occurs when there is gradual faecal impaction of the colon, but DIOS occurs when there is an accumulation of faeces and sticky mucus, forming a mass in the distal part of the small intestine. The mass may partially block the intestine (incomplete DIOS) or completely block the intestine (complete DIOS). Symptoms of DIOS can affect quality of life and other aspects of CF health, such as airway clearance, exercise, sleep and nutritional status. Treatment of constipation and prevention of complete bowel obstruction are required for gastrointestinal management in CF. However, many different strategies are used in clinical practice and there is a lack of consensus. The importance of this topic was highlighted in a recent research priority setting exercise by the James Lind Alliance. OBJECTIVES To evaluate the effectiveness and safety of laxative agents of differing types for preventing DIOS (complete and incomplete) in children and adults with CF. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. Date of search: 09 September 2021. We also searched online trial registries. Date of last search: 12 October 2021. SELECTION CRITERIA Randomised and quasi-randomised controlled parallel trials comparing laxative therapy for preventing DIOS (including osmotic agents, stimulants, mucolytics and substances with more than one action) at any dose to placebo, no treatment or an alternative laxative therapy, in people of any age with pancreatic sufficient or insufficient CF and any stage of lung disease. Randomised cross-over trials were judged on an individual basis. DATA COLLECTION AND ANALYSIS Two authors independently assessed trials for inclusion, extracted outcome data and performed a risk of bias assessment for the included data. We judged the certainty of the evidence using GRADE criteria. MAIN RESULTS We included one cross-over trial (17 participants) with a duration of 12 months, in which participants were randomly allocated to either cisapride (a gastro-prokinetic agent) or placebo for six months each. The trial had an unclear risk of bias for most domains but had a high risk of reporting bias. Radiograph scores revealed no difference in occurrence of DIOS between cisapride and placebo (narrative report, no data provided). There were no adverse effects. Symptom scores were the only secondary outcome within the review that were reported. Total gastrointestinal symptom scores favoured cisapride with a statistically significant mean difference (MD) of -7.60 (95% confidence interval (CI) -14.73 to -0.47). There was no significant difference at six months between cisapride and placebo for abdominal distension, MD -0.90 (95% CI -2.39 to 0.59) or abdominal pain, MD -0.4 (95% CI -2.05 to 1.25). The global symptom scores (whether individuals felt better or worse) were reported in the paper to favour cisapride and be statistically significant (P < 0.05). We assessed the available data to be very low certainty. There was a great deal of missing data from the included trial and the investigators failed to report numerical data for many outcomes. The overall risk of bias of the trial was unclear and it had a high risk for reporting bias. There was also indirectness; the trial drug (cisapride) has since been removed from the market in several countries due to adverse effects, thus it has no current applicability for preventing DIOS. The included trial also had very few participants, which downgraded the certainty a further level for precision. AUTHORS' CONCLUSIONS There is an absence of evidence for interventions for the prevention of DIOS. As there was only one included trial, we could not perform a meta-analysis of the data. Furthermore, the included trial compared a prokinetic agent (cisapride) that is no longer licensed for use in a number of countries due to the risk of serious cardiac events, a finding that came to light after the trial was conducted. Therefore, the limited findings from the trial are not applicable in current clinical practice. Overall, a great deal more research needs to be undertaken on gastrointestinal complications in CF, as this is a very poorly studied area compared to respiratory complications in CF.

Abstract
PURPOSE The effectiveness of using anti-adhesion agents in laparoscopic surgery is controversial. We compared the outcomes of patients exposed to anti-adhesion agents (barrier group) with those of patients not exposed (no barrier group) in laparoscopic surgery. METHODS Using a nationwide claim-based database in Japan, we analyzed data from patients who underwent laparoscopic surgery between 2005 and 2019 and compared the patient characteristics and the proportion of those with bowel obstruction between the barrier and no barrier groups. We also performed several sensitivity and subgroup analyses. RESULTS Of the 57,499 patients who met the inclusion criteria, 14,360 and 43,139 were assigned to the barrier and no barrier groups, respectively. The proportion of patients with a bowel obstruction in the two groups did not differ among all patients hospitalized for obstruction (1.1 vs. 1.1%, p = 0.63) and those requiring surgery (0.2 vs. 0.2%, p = 0.39). In the sensitivity analysis with propensity score matching, the incidences of bowel obstruction between the barrier and non-barrier groups were equivocal (1.3 vs. 1.6%), but statistically marginal (chi-square test, p = 0.035; log-rank test, p = 0.09). CONCLUSION The use of barrier agents for adhesive prevention did not show clear effectiveness for the prevention of bowel obstruction after laparoscopic surgery for unselected cases. Further studies focusing on more specific procedures are needed.

Abstract
Context Cystic fibrosis (CF) is an autosomal recessive genetic disorder primarily affecting the lungs and digestive system. Patients with CF often have multiorgan dysfunction, including chronic lung infections, pancreatic insufficiency, chronic constipation, and distal intestinal obstructive syndrome (DIOS). Objective To understand the impact of osteopathic manipulative treatment (OMT) on the prevention and management of gastrointestinal symptoms in patients with CF. Methods This study used OMT for physical manipulation of the viscera, spine, and other somatic components to improve bowel symptoms and prevent DIOS. These effects were achieved by releasing myofascial restrictions found in the abdomen and somatic structures with the intent to optimize the autonomic and lymphatic systems and improve range of motion. Results Four of 5 participants had a decrease in pain, and 3 participants had a reduced need for laxatives during treatment. Four participants had an overall increase in satisfaction with their bowel movements while being treated with OMT. Conclusion These findings support the use of OMT as a method for the management of chronic constipation and DIOS in the CF population. However, because of the small population size, more research with larger populations is needed.

Abstract
Neuroendocrine tumours of the small intestine (SINET) are a rare disease. However, a rising incidence rate and excellent long-term survival, even in the setting of metastatic disease lead to a high prevalence of SINET of up to 11/100.000. At the time of diagnosis, most patients already suffer from metastatic disease. About one third of patients demonstrate localized or regional metastatic disease at time of presentation. For those patients the indication for curative surgery is not debated and 10-year cancer specific survival of almost 90% can be achieved. Due to major limitations of existing studies actually there is no sufficient evidence in favour of ileus-prophylactic palliative surgery for metastatic SINET. Until now the available evidence favouring an ileus-prophylactic palliative small bowel resection for stage IV SI-NET must be weighed against available high-level evidence from randomized trials that showed long-term survival under systemic therapy. Importantly, there is not a single study that indicates surgery for a symptomatic patient should be postponed. Because the majority of patients are symptomatic at the time of diagnosis, the rationale for an ileus-prophylactic palliative surgery is to operate before progression of mesenteric tumour mass and desmoplasia takes place and before intestinal obstruction and ischaemia occurs. To what extent a prophylactic palliative small bowel resection will provide a survival benefit in a situation where the mesenteric tumour mass cannot be resected radically is not clearly addressed by the current level of evidence.

Abstract
BACKGROUND Guardix-SG is a poloxamer-based antiadhesive agent. The aim of this study was to investigate its efficacy in preventing abdominal adhesions in gastric cancer patients undergoing gastrectomy. Few clinical studies have reported that antiadhesive agent reduces the incidence of adhesion after gastrectomy. METHODS We conducted a multicenter trial from June 2013 and August 2015 in patients with gastric adenocarcinoma undergoing radical gastrectomy. Patients were randomly assigned to the Guardix treatment or control group. Postoperative adhesions were diagnosed based on postoperative symptoms, plain x-ray films, and computed tomography. The primary endpoint of the study was the incidence of small bowel obstruction in the first postoperative year. The secondary end-point was the safety of Guardix-SG. RESULTS The study included 109 patients in the Guardix group and 105 patients in the control group. The groups were similarly matched with pathological stage, operation type, anastomosis method, midline incision length, and the extent of lymph node dissection. Eight in the Guardix group and 21 in the control group experienced intestinal obstruction during the 1-year follow-up period. The cumulative incidence of small bowel obstruction was significantly lower in the Guardix group compared to that seen in the control group (4.7% vs 8.6% at 6 months and 7.3% vs 20% at 1 year; P = .007, log-rank test). There were no differences in postoperative complications and adverse events. CONCLUSION Guardix-SG significantly decreased the incidence of intestinal obstruction without affecting the incidence of postoperative complications.

Abstract
OBJECTIVES Intestinal obstruction has a high mortality rate when therapeutic treatment is delayed. Resuscitation in intestinal obstruction requires a large volume of fluid, and fluid combinations have been studied. Therefore, we evaluated the effects of hypertonic saline solution (HS) with pentoxifylline (PTX) on apoptosis, oxidative stress and survival rate. METHODS Wistar rats were subjected to intestinal obstruction and ischemia through a closed loop ligation of the terminal ileum and its vessels. After 24 hours, the necrotic bowel segment was resected, and the animals were randomized into four groups according to the following resuscitation strategies: Ringer's lactate solution (RL) (RL-32 ml/kg); RL+PTX (25 mg/kg); HS+PTX (HS, 7.5%, 4 ml/kg), and no resuscitation (IO-intestinal obstruction and ischemia). Euthanasia was performed 3 hours after resuscitation to obtain kidney and intestine samples. A malondialdehyde (MDA) assay was performed to evaluate oxidative stress, and histochemical analyses (terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling [TUNEL], Bcl-2 and Bax) were conducted to evaluate kidney apoptosis. Survival was analyzed with another series of animals that were observed for 15 days. RESULTS PTX in combination with RL or HS reduced the MDA levels (nmol/mg of protein), as follows: kidney IO=0.42; RL=0.49; RL+PTX=0.31; HS+PTX=0.34 (p<0.05); intestine: IO=0.42; RL=0.48; RL+PTX=0.29; HS+PTX=0.26 (p<0.05). The number of labeled cells for TUNEL and Bax was lower in the HS+PTX group than in the other groups (p<0.05). The Bax/Bcl-2 ratio was lower in the HS+PTX group than in the other groups (p<0.05). The survival rate on the 15th day was higher in the HS+PTX group (77%) than in the RL+PTX group (11%). CONCLUSION PTX in combination with HS enhanced survival and attenuated oxidative stress and apoptosis. However, when combined with RL, PTX did not reduce apoptosis or mortality.

Abstract
Small intestinal neuroendocrine tumors (SI-NETs) may demonstrate a widely variable clinical behavior but usually it is indolent. In cases with localized disease, locoregional resective surgery (LRS) is generally indicated with a curative intent. LRS of SI-NETs is also the recommended treatment when symptoms are present, regardless of the disease stage. Concerning asymptomatic patients with distant metastases, prophylactic LRS has been traditionally suggested to avoid possible future complications. Even the current European Neuroendocrine Tumor Society guidelines emphasize a possible effect of LRS in Stage IV SI-NETs with unresectable liver metastases. On the contrary, the 2017 National Comprehensive Cancer Network Guidelines on carcinoid tumors do not support the resection of a small, asymptomatic, relatively stable primary tumor in the presence of unresectable metastatic disease. Furthermore, a recent study revealed no survival advantage for asymptomatic patients with distant-stage disease who underwent upfront LRS. At the aforementioned paper, it was suggested that delayed surgery as needed was comparable with the upfront surgical approach in terms of postoperative morbidity and mortality, the length of the hospital stay and the rate of incisional hernia repairs but was associated with fewer reoperations for bowel obstruction. On the other hand, it is also important to note that some patients might benefit from a prophylactic surgical approach and our attention should focus on identifying this patient population.

Abstract
BACKGROUND Cystic fibrosis (CF) is the most common, life-limiting, genetically inherited disease. It affects multiple organs, particularly the respiratory system. However, gastrointestinal problems such as constipation and distal intestinal obstruction syndrome (DIOS) are also important and well-recognised complications in CF. They share similar symptoms e.g. bloating, abdominal pain, but are distinct conditions. Constipation occurs when there is gradual faecal impaction of the colon, but DIOS occurs when there is an accumulation of faeces and sticky mucus, forming a mass in the distal part of the small intestine. The mass may partially block the intestine (incomplete DIOS) or completely block the intestine (complete DIOS). Symptoms of DIOS can affect quality of life and other aspects of CF health, such as airway clearance, exercise, sleep and nutritional status. Treatment of constipation and prevention of complete bowel obstruction are required for gastrointestinal management in CF. However, many different strategies are used in clinical practice and there is a lack of consensus. The importance of this topic was highlighted in a recent research priority setting exercise by the James Lind Alliance. OBJECTIVES To evaluate the effectiveness and safety of laxative agents of differing types for preventing DIOS (complete and incomplete) in children and adults with CF. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. Date of search: 22 May 2018.We also searched online trial registries. Date of last search: 10 June 2018. SELECTION CRITERIA Randomised and quasi-randomised controlled parallel trials comparing laxative therapy for preventing DIOS (including osmotic agents, stimulants, mucolytics and substances with more than one action) at any dose to placebo, no treatment or an alternative laxative therapy, in people of any age with pancreatic sufficient or insufficient CF and any stage of lung disease. Randomised cross-over trials were judged on an individual basis. DATA COLLECTION AND ANALYSIS Two authors independently assessed trials for inclusion, extracted outcome data and performed a risk of bias assessment for the included data. We judged the quality of the evidence using GRADE criteria. MAIN RESULTS We included one cross-over trial (17 participants) with a duration of 12 months, in which participants were randomly allocated to either cisapride (a gastro-prokinetic agent) or placebo for six months each. The trial had an unclear risk of bias for most domains but had a high risk of reporting bias.Radiograph scores revealed no difference in occurrence of DIOS between cisapride and placebo (narrative report, no data provided). There were no adverse effects. Symptom scores were the only secondary outcome within the review that were reported. Total gastrointestinal symptom scores favoured cisapride with a statistically significant mean difference (MD) of -7.60 (95% confidence interval (CI) -14.73 to -0.47). There was no significant difference at six months between cisapride and placebo for abdominal distension, MD -0.90 (95% CI -2.39 to 0.59) or abdominal pain, MD -0.4 (95% CI -2.05 to 1.25). The global symptom scores (whether individuals felt better or worse) were reported in the paper to favour cisapride and be statistically significant (P < 0.05).We assessed the available data to be very low quality. There was a great deal of missing data from the included trial and the investigators failed to report numerical data for many outcomes. The overall risk of bias of the trial was unclear and it had a high risk for reporting bias. There was also indirectness; the trial drug (cisapride) has since been removed from the market in several countries due to adverse effects, thus it has no current applicability for preventing DIOS. The included trial also had very few participants, which downgraded the quality a further level for precision. AUTHORS' CONCLUSIONS There is an absence of evidence for interventions for the prevention of DIOS. As there was only one included trial, we could not perform a meta-analysis of the data. Furthermore, the included trial compared a prokinetic agent (cisapride) that is no longer licensed for use in a number of countries due to the risk of serious cardiac events, a finding that came to light after the trial was conducted. Therefore, the limited findings from the trial are not applicable in current clinical practice.Overall, a great deal more research needs to be undertaken on gastrointestinal complications in CF, as this is a very poorly studied area compared to respiratory complications in CF.

Abstract
INTRODUCTION Classic surgical teaching advocates for closure of the mesenteric defect (MD) after bowel anastomosis but the necessity is controversial. We sought to evaluate the necessity of MD closure at the time of harvest of ileum for genitourinary reconstructive surgery (GURS) by analyzing the incidence of early and late gastrointestinal adverse events (GIAE) in patients with and without MD closure. MATERIALS AND METHODS A retrospective review was conducted on patients undergoing urologic reconstruction with ileum to identify incidence of ileus, small bowel obstruction (SBO), gastrointestinal (GI) fistula and stoma complications. Patient and procedure variables were analyzed to identify risk factors for GIAE. RESULTS A total of 288 patients met inclusion criteria and 93% of GURS was for urinary diversion following cystectomy. MD was closed in 194 cases (67%). Median follow up was 19 months. Early (< 30 day) GIAE rates were 16.5% (n = 32) and 21.3% (n = 20) in the closure and non-closure groups, respectively (p = 0.22). The rate of early ileus/SBO requiring nasogastric tube decompression or laparotomy were similar after closure (15.0%) and non-closure (21.3%) (p = .18). The late GIAE rates were 5.7% (n = 11) and 6.4% (n = 6) in the closure and non-closure cohorts, respectively (p = 0.56). The rate of late SBO were similar and no cases of early or late SBO in either cohort were due to internal herniation. On multivariate analysis, increasing BMI was associated with both early and late GIAE. CONCLUSIONS After harvesting ileum for urologic reconstruction, the MD can safely be left open as we found no association between non-closure and early or late GIAE..

Abstract
BACKGROUND Pancreatic cancer is a formidable health problem, representing the 10th most common malignancy in the United States and the 4th most common cause of all cancer deaths. The overall 5-year survival rate is 4%, making this disease a model tumor in which to address the specialized care issues of palliative medicine. METHODS General considerations in both medical decision-making and symptom management are reviewed. Treatment of patients with locally unresectable, recurrent, or metastatic disease is individualized, based on considerations that include patient age, patient wishes, family influence, insurance constraints, and geographic practice variations. RESULTS Success in managing progressive symptoms is needed to palliate patients with advanced pancreatic cancer. Common problems include biliary obstruction, depression, pain, intestinal obstruction, and fatigue. CONCLUSIONS Relief of pain and suffering associated with critical illness is required in managing patients with cancer. Pancreatic cancer is a model illness that mandates this need.

Abstract
A wide range of complications may occur after Roux-en-Y gastric bypass (RYGB) surgery, including surgical, medical/nutritional, and psychiatric complications. Some of the nutritional complications such as anaemia, dumping and hypoglycaemia may present rather unspecific symptoms that may easily not be diagnosed as complications after RYGB. Focus on diagnosis and treatment of these complications is important.

Abstract
Objetivo: Mostrar la eficacia de la FI para prolongar el tiempo libre de oclusión intestinal quirúrgica en niños con abdomen hostil secundario a bridas posquirúrgicas. Método: Análisis retrospectivo de FI por abdomen hostil de 2000 a 2011 y su seguimiento a largo plazo. Comparamos el tiempo libre de oclusión quirúrgica antes y después de la FI. Resultados: Se incluyeron 20 FI en 19 pacientes. Predominaron las causas congénitas, la mediana de edad en la cirugía fue de 6 meses, todos tenían cirugías previas con mediana de tres, y dos de ellas fueron por oclusión intestinal previa. La férula se quitó a los 28 días (mediana). Con un seguimiento de 1-183 meses, hubo una recurrencia de oclusión quirúrgica. El tiempo libre de oclusión quirúrgica posferulización fue significativamente mayor que el preferulización mediante la prueba de Wilcoxon, con un valor Z = -3.594; p = < 0.0001. Conclusiones: Esta es la segunda serie exclusiva en niños que muestra que la FI es eficaz para prolongar el tiempo libre de oclusión quirúrgica.

Abstract
The introduction of knotless barbed suture into the surgical market has decreased the challenges of laparoscopic suturing. Since its introduction, barbed suture has gained popularity in the field of minimally invasive gynecologic surgery and is now commonly used to close the vaginal cuff in total laparoscopic hysterectomy, to re-approximate the myometrium after laparoscopic myomectomy, and to shorten the procedure time during a laparoscopic sacrocolpopexy. Barbed sutures facilitate rapid and consistent wound closure, allowing for equal distribution of tissue tension across the suture line, and thereby providing a more secure wound closure. The most commonly encountered complication after the use of barbed sutures is postoperative bowel obstruction. Proposed methods to decrease the likelihood of this complication include ensuring that the ends of the barbed suture are either buried, over-sewn, or cut flush with the tissue.

Abstract
Intestinal obstruction is the most common complication after gastrointestinal surgery, and will endanger the patients if not managed properly. The key to the management of intestinal obstruction includes not only the selection of treatment, but also adequate judgment of the cause, location, extent and the probability of reoperation by detailed inquiry of the history, thorough physical examination, and imaging studies, which will guide the treatment. Non-operative therapy is the mainstay of treatment for incomplete obstruction, whilebowel decompression the gut by small intestinal decompression tube, preoperative procedures including restoration of systemic homeostasis should be performed. Efforts should be made to avoid emergency laparotomy without any preparations. Procedures to avoid intestinal obstruction include all the efforts to protect the gut and the intra-abdominal viscera during laparotomy, and to clear all the foreign body and tissues by thorough lavage of the abdominal cavity with saline before closing the abdomen.

Abstract
Intestinal fibrosis is a common feature of Crohn's disease and may appear as a stricture, stenosis, or intestinal obstruction. Fibrostenosing Crohn's disease leads to a significantly impaired quality of life in affected patients and constitutes a challenging treatment situation. In the absence of specific medical antifibrotic treatment options, endoscopic or surgical therapy approaches with their potential harmful side effects are frequently used. However, our understanding of mechanisms of fibrogenesis in general and specifically intestinal fibrosis has emerged. Progression of fibrosis in the liver, lung, or skin can be halted or even reversed, and possible treatment targets have been identified. In face of this observation and given the fact that fibrotic alterations in various organs of the human body share distinct core characteristics, this article aims to address whether reversibility of intestinal fibrosis may be conceivable and to highlight promising research avenues and therapies.

Abstract
Stoma formation is commonly performed in operations to treat carcinoma, inflammatory bowel disease (IBD) and familial adenomatous polyposis (FAP). In this study, we report several cases of stomal outlet obstruction and investigate the clinical features of cases of outlet obstruction in patients who underwent diverting loop ileostomy. Sixty-one patients with IBD, FAP or rectal cancer who required diverting loop ileostomy were identified for inclusion in this study. We defined outlet obstruction as a small bowel obstruction at the opening of the ileostomy following surgery. All cases of outlet obstruction were diagnosed by computed tomography. In the univariate analysis the type of diagnosis, type of operation, age, and white blood cell count were the factors significantly associated with outlet obstruction following ileostomy, and outlet obstruction was considered to have a connection with restorative proctocolectomy. In conclusion, we found that adhesion and twisting of the ileostomy were the causes of outlet obstruction. For temporary diversion, simple rotation of the ileostomy should be recommended, especially in restorative proctocolectomy. Additional study is required to explore other risk factors of outlet obstruction.

Abstract
Influence of therapeutic plasmapheresis on bowel barrier function and evacuation was investigated in 83 patients with severe acute necrotizing pancreatitis. Except standard therapy patient obtained therapeutic plasmapheresis using "Haemonetics" PCS 2 system. Complex treatment of patients with acute necrotizing pancreatitis and dynamic ileus using plasmapheresis increases contractive and propulsive function of stomach and duodenum and prolongs period of activity of these organs on 32%. Intestinal barrier function associates with restoration of bowel evacuation. Addition of plasmapheresis to standard therapy of necrotizing pancreatitis can be effective prevention of dynamic ileus.

Abstract
Postoperative adhesions are a natural consequence of surgical tissue trauma and healing and may result in infertility, pain, and bowel obstruction. Adherence to microsurgical principles and minimally invasive surgery may help to decrease postoperative adhesions. Some surgical barriers have been demonstrated effective for reducing postoperative adhesions, but there is no substantial evidence that their use improves fertility, decreases pain, or reduces the incidence of postoperative bowel obstruction. This document replaces the document of the same name last published in 2008 (Fertil Steril 2008;90[5 Suppl]:S144-9).

Abstract
Sigmoid volvulus (SV) is the third leading cause of colon obstruction in adults. In infants and children, it is exceedingly rare with only sporadic cases reported so far. SVs from secondary causes, with congenital megacolon being the most important, are nevertheless more common in young people. The etiology of this disorder is not completely understood. It is known to occur in the setting of redundant sigmoid loop, which rotates around its narrow and elongated mesentery. Although the latter occurs in the setting of constipation, a congenitally elongated colon, and other predisposing factors, there is no consensus on the precipitating factor leading to SV formation. The symptoms are suggestive of small bowel obstruction, but the presentations can be acute or indolent. Plain abdominal radiography is used to diagnose SV in most cases with computed tomography scan or magnetic resonance imaging as the confirmatory tests when necessary. After it has been untwisted, the definitive and standard therapy for SV is sigmoid resection and primary anastomosis. The nonresective alternatives have also been widely used with mixed success, but a large, randomized controlled trial is needed to compare their efficacy with resection and primary anastomosis. Laparoscopic surgery in SV management is unwarranted and costly. Complications of SV include hemorrhagic infarction, perforation, septic shock, and death. The mortality data from SV vary, but the latest literature cites an overall range of 14 to 45 per cent.

Abstract
Formation of postoperative adhesions is frequent in open surgery technique operations. By causing intestinal obstruction, infertility and very likely chronic abdominal pain and by complicating reoperations they place a significant burden on the health care system. The risk of formation of adhesions is high in colorectal surgery and adnexal surgery. Their formation is also increased by intraoperative peritonitis and contamination. Factors that can be applied to prevent the formation of adhesions include the surgical technique and instruments and products decreasing the formation of adhesions.

Abstract
In this study, we analyzed temporal trends in anti-adhesion barrier application and admission rates for small bowel obstruction. We used data from the Nationwide Inpatient Sample and identified patients with ICD-9 codes for "application or administration of anti-adhesion barrier substances" from October 2002 through December 2007. Next, we identified cases of bowel obstruction coded from January 1997 through December 2007. We then used Kendall correlation analyses and the Joinpoint regression program to evaluate changes in trends. From October 1, 2002 through December 31, 2007, a total of 28,014 patients had an anti-adhesion barrier substance applied. During the study period, application of anti-adhesion barriers increased from 0.7 applications per 100,000 to 2.6 applications per 100,000 population (Joinpoint and Kendall; P < 0.002). Since 1997 there has been a steady rise in hospitalizations for bowel obstruction, increasing from 18.3 cases per 100,000 to 19.8 cases per 100,000 population (Joinpoint and Kendall; P < 0.002). In conclusion, the application of anti-adhesion barriers has increased significantly since 2002, yet bowel obstructions continue to be a major health problem.

Abstract
BACKGROUND Conventionally, an adult's standard of a 40-cm loop is adopted in Roux-Y hepatojejunostomy (RYHJ) in choledochal cyst (CDC) in children, irrespective of patient size. The redundant length of the jejunal limb may lead to complications. We compared the outcome of an individualized short Roux loop with the standard loop length in RYHJ in children with CDC. METHODS Two hundred eighteen children with CDC undergoing laparoscopic RYHJ were prospectively randomized into 2 groups: (1) conventional group (CG; n = 108) where a standard 35-40 cm Roux-loop length was used regardless of the child's size and (2) short loop group (SLG; n = 110) in which the Roux-loop length was based on the distance between hepatic hilum and umbilicus. Ultrasonography, upper gastrointestinal contrast studies, and laboratory tests were conducted during the follow-up period. RESULTS The mean Roux-loop length of SLG was significantly shorter than that of CG (Student t test, P < .05). There was no significant difference between the 2 groups in age, operative blood loss, operative time, postoperative hospital stay, and duration of drainage. In CG, 2 of (1.8%) 108 patients developed Roux-loop obstruction, whereas none was detected in SLG (0%). Mild reflux was detected in 2 CG patients and 1 SLG patient 1 month postoperatively, all of which subsided 6 months later. No episodes of cholangitis were observed in either group. CONCLUSIONS An individualized short Roux-loop length in RYHJ is as effective as the conventional Roux-loop length.

Abstract
Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving a critical clinical condition of Polycompartment Syndrome. The monitoring of Abdominal Perfusion Pressure (APP) is more correct than the measurement of IAP because it reveals hydrodynamic alterations in the abdominal compartment. The APP (MAP-IAP) depends on arterial flow, venous outflow and capacity of the abdominal compartments response to increased internal volumes. The medical therapy used to decrease IAH and to contrast ACS is intestinal decompression with gastric and rectal tube; colonic endoscopic detention; correction of electrolytic abnormalities and prokinetic agents. Surgery, besides being decompressive and resolutive, must prevent a recurrence of ACS through the "tension-free closure" procedure.

Abstract
Mechanical small bowel obstruction (SBO) remains a common clinical problem despite ever-increasing medical and surgical advances. The predominant etiology continues to be postoperative adhesions, accounting for approximately two-thirds of all obstructive events. As opposed to high-grade or complete small bowel obstruction where the clinical and radiographic findings are typically more diagnostic and the treatment plan more defined, partial SBO represents a subgroup, where the evaluation is more arduous, the diagnosis more elusive, and the management less defined. Operative and nonoperative approaches to treatment are successful and are based on the etiology and clinical status of the patient. A paradox remains, however, treating a predominantly surgically induced condition with repeated operations. Several advances in the treatment and prevention of SBO have become practice in past decade. This article reviews the clinical issues and technical advances of this challenging condition.

Abstract
The objective of this study was to assess antiemetic efficacy of granisetron in inoperable intestinal obstruction caused by advanced cancer. The study was open, prospective, and multi-centered. We assessed 24 patients (mean age: 61.3 years; 10 males, 14 females) with intestinal obstruction who were refractory to previous antiemetics. Obstruction involved the upper intestine in six patients, the lower intestine in three, and was at multiple levels in 15. Daily treatment included intravenous granisetron (3mg) and dexamethasone (8 mg); nasogastric drainage was not allowed. Subcutaneous haloperidol was available as rescue therapy. A numeric scale was used to evaluate nausea, pain, asthenia, and anorexia at baseline visit and every 24 hours up to the completion of four days of treatment (final visit). Treatment failure was defined as nausea >4 on the numeric scale, vomiting 2/day or more, and rescue therapy with haloperidol at 5mg/day or more. Of the 24 patients, 23 were evaluable for efficacy. Evaluation pre- vs. post-treatment indicated a significant decrease in the severity of nausea (score 6.9 vs. 0.8; P<0.001), number of episodes of vomiting (5.3 vs. 1.0; P<0.001), and abdominal pain (score 4.4 vs. 1.2; P<0.001). Nausea and vomiting control was achieved in 86.9% of patients. Although there was a trend toward greater efficacy in the lower and multiple levels of obstruction, the differences were not statistically significant owing, probably, to small sample size. We conclude that granisetron may be highly efficacious in the control of emesis resulting from intestinal obstruction caused by metastatic cancer, and can be used effectively in patients refractory to other antiemetics.

Abstract
BACKGROUND Intra-abdominal adhesions are common and challenge patients, surgeons and other healthcare providers. They are potentially preventable and several agents that act as barriers between adjacent peritoneal surfaces have been evaluated for prophylaxis. Efficacy, judged by systematic reviews, has only been undertaken in gynaecological surgery. OBJECTIVES To determine efficacy and safety of peritoneal adhesion prophylaxis on incidence, distribution and adhesion-related intestinal obstruction after non-gynaecological surgery. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials, the Cochrane Colorectal Cancer Group specialised register, MEDLINE (1966-2008), and EMBASE (1971-2008) were searched. SELECTION CRITERIA Blinded and non-blinded, randomised and quasi-randomised clinical trials were considered. DATA COLLECTION AND ANALYSIS Two authors individually conducted the searches and assessed the quality of studies for inclusion which were analysed using the Revman Analyses software 5.0.0 provided by the Cochrane collaboration. Meta-analysis used a random effects model. MAIN RESULTS Seven randomised trials were eligible; six compared hyaluronic acid/carboxymethyl membrane (HA/CMC) and one 0.5% ferric hyaluronate gel against controls.HA/CMC reduced the incidence of adhesions (OR 0.15 (95% CI: 0.05, 0.43); p=0.0005) with reduced extent (WMD -25.9% (95% CI: -40.56, -11.26); p=0.0005) and severity. There was no reduction of intestinal obstruction needing surgical intervention (odds ratio: 0.84 (95% CI: 0.24, 2.7) with comparable overall morbidity and mortality.The study of 0.5% ferric hyaluronate gel was prematurely terminated and no valid conclusions could be made but there was a higher incidence of overall morbidity (OR 5.04; 95% CI: 1.1, 22.9) and ileus (OR: 9.29; 95% CI: 1.57, 54.77; p=0.01). IMPLICATIONS FOR PRACTICE There is evidence that the use of HA/CMC membrane reduces incidence, extent and severity of adhesions which may, theoretically, have implications in re-operative abdominal surgery. There is no evidence that the incidence of intestinal obstruction or need for operative intervention is reduced. HA/CMC appears to be safe but there may be a risk of leak when wrapped around an anastomoses. HA/CMC may be considered for intra-abdominal, adhesion prophylaxis at a surgeon's discretion and clinical context. IMPLICATIONS FOR RESEARCH Further research is needed to explore the effectiveness of other agents in abdominal surgery in general. Synergism, using agents which target different aspects of adhesiogenesis, with exploration effectiveness in a wide range of emergency and elective surgery should be considered. Longer term outcomes of recurrent intestinal obstruction and chronic pain, identification of high risk groups of patients with evaluation of cost-effectiveness are required.

Abstract
Adhesive process in the abdominal cavity is the leading cause of morbidity and mortality in abdominal surgery. The clinical investigation included 126 children with acute adhesive intestinal obstruction. All patients were divided into two groups: polyenzyme and monoenzyme groups. In the polyenzyme group there was one case of intestinal obstruction. In the monoenzyme group there were 4 children with intestinal obstruction. The experiment included 70 adult rats divided in two equal groups: the main and control groups. The main group animals were given a polyenzyme preparation. The control group had a high incidence of cecal adhesions, which was significantly higher than the number of adhesions in the main group (Chi-square test = 23.1, df=2, p = 0.001). Proteolytic enzymes induce cells to express, de novo, the vascular endothelial growth factor, fibroblast growth factor and Laminin. As a consequence of these effects, activation of T-lymphocytes and macrophages mediating the inflammatory response will be down-regulated. It was found that the levels of VEGF, FGF and Laminin in the abdominal cavity, detected by immunohistochemistry, were different in the rats having high level and having no postoperative abdominal adhesion. The level of angiogenesis factors was also rapidly normalized by means of polyenzyme therapy.

Abstract
INTRODUCTION There are conflicting studies on the influence of fractionated preoperative 5 days of 5 Gy irradiation on tissue oxygenation and subsequent colonic anastomotic strength. To elucidate the effect of preoperative irradiation on anastomotic strength, an isolated colon loop model was developed. METHODS Male Wistar rats (n = 164) were randomly divided into three groups. One group remained untreated (control). In the other two groups, a loop of descending colon was exteriorized to create a hernia of the abdominal wall. After 4 weeks' recovery, this loop was locally irradiated with 5 x 5 Gy of gamma-rays or sham irradiated. One week after (sham-) irradiation, an anastomosis was performed in all groups. Tissue oxygenation (StO2) was determined with visible light spectroscopy. The animals were sacrificed 3 or 7 days after the operation and the anastomosis was tested for bursting pressure and breaking strength. RESULTS Irradiated rats showed significantly more weight loss (90% SD 4.3 of initial body weight vs. 96% SD 2.8, p < or = 0.05) and enteritis (18% vs. 5%, p = 0.013) compared to sham and control animals. StO2 was not influenced by irradiation and was not predictive for anastomotic strength. The control group showed significantly lower bursting pressure and breaking strength compared to (sham-) irradiated animals. CONCLUSION We developed a new isolated loop model for intermittent irradiation of the colon. Preoperative irradiation of the distal part of a colon anastomosis was successfully administered with acceptable side effects and did not cause reduced tissue oxygenation nor clinical signs of anastomotic weakening, nor objective reduction in bursting pressure and breaking strength.

Abstract
To elucidate the impact of nutrition in cystic fibrosis (CF), we compared the phenotypic traits of Cftr -/- mice fed either a lipid-enriched liquid diet (Peptamen) or a standard chow combined with polyethylenglycol osmotic laxative (PEG), two strategies commonly used to prevent intestinal obstruction in CF mice. Survival, growth, liver, and ventilatory status were determined in Cftr -/- and Cftr +/+ mice, followed-up until 120 d. Ventilation was recorded in conscious animals using whole-body plethysmography. We found that the survival rate was similar in Peptamen and PEG Cftr -/- mice. Cftr -/- mice had lower minute ventilation than Cftr +/+ mice, whatever the diet. Both Cftr -/- and Cftr +/+ mice fed Peptamen displayed preadult growth delay compared with PEG-treated animals. Despite subsequent growth catch-up, Cftr -/- mice remained smaller than Cftr +/+ mice, whatever the diet. All Peptamen fed Cftr -/- mice showed hepatomegaly and liver steatosis, which also occurred but to a lesser extent in Peptamen fed Cftr +/+ animals. Therefore, while both treatment strategies are similarly efficient to avoid high mortality at weaning, Peptamen induces preadult growth delay and liver steatosis. These effects of diet are important to consider in future animal studies and also prompt to evaluate high-energy diets in CF patients.

Abstract
Intraabdominal adhesions develop after abdominal surgery as part of the normal healing processes that occur after damage to the peritoneum. Over the last 2 decades, much research has gone into understanding the biochemical and cellular processes that lead to adhesion formation. The early balance between fibrin deposition and degradation seems to be the critical factor in adhesion formation. Although adhesions do have some beneficial effects, they also cause significant morbidity, including adhesive small bowel obstruction, infertility and increased difficulty with reoperative surgery. Several strategies have been employed over the years to prevent adhesion formation while not interfering with wound healing. This article summarizes much of our current understanding of adhesion formation and strategies that have been employed to prevent them.

Abstract
The present study investigated the effect of Daikenchuto (DKT) on postoperative intestinal adhesion in rats. We evaluated the effects of DKT, constituent medical herbs and active compounds on talc-induced intestinal adhesion in rats and DKT-induced contractions using isolated guinea pig ileum. DKT significantly prevented adhesion formation, and this action was inhibited by pretreatment with atropine or ruthenium red. The constituent medical herbs, Zanthoxylum Fruit and Maltose Syrup Powder significantly prevented adhesion formation. Moreover, hydroxy sanshool (HS) prevented adhesion formation, and this action was inhibited by pretreatment with ruthenium red. In contrast, DKT-induced contractions were inhibited by tetrodotoxin, atropine, and capsazepine. These results suggested that DKT had a preventive action on postoperative adhesive intestinal obstruction, and that this action was mediated by sensory and cholinergic nerves. Furthermore, HS was found to be one of the active compound of DKT, and its action was mediated by sensory nerves.

Abstract
Exposure of the ligament of Treitz for Roux limb construction during laparoscopic gastric bypass requires either division or displacement of the omentum. Factors compromising this exposure include: (1) a bulky omentum, (2) hepatomegaly, (3) adhesions between the omentum and lower abdominal wall or pelvic contents and (4) inability to identify the transverse colon because of overlying adipose tissue. The lesser sac approach is an alternative method for Roux limb construction during laparoscopic gastric bypass when access to the inframesocolic abdomen is difficult. In this technique the lesser sac is entered through the gastrocolic ligament. The transverse mesocolon is then opened and the ligament of Treitz is identified. The jejunum is pulled into the lesser sac and the Roux limb is constructed. The jejunojejunostomy is reduced into the inframesocolic compartment, the mesenteric defects are closed, and the remaining portion of the procedure is completed. This technique provides an alternative method for completion of a laparoscopic gastric bypass in patients who would otherwise require more extensive surgery.

Abstract
OBJECTIVE To explore the diagnosis and surgical treatment of abdominal cocoon. METHODS The clinical data of 16 patients with abdominal cocoon admitted to our hospital between Jun. 1993 and Oct. 2006 were analyzed retrospectively. RESULTS Preoperatively, Barium meal X-rays revealed coils of intestine in 8 cases, incomplete intestinal obstruction in 6 cases, and prolonged intestinal transit time in 2 cases. CT scan showed dilated intestine and intestinal loops seemed to be encapsulated in a thickened capsule. After opening the peritoneum, entire or partial intestine encapsulated in thickened membrane encasing were found, including partial intestine encapsulated in 1 cases(Type I), entire intestine encapsulated in 2 cases (Type II), and entire intestine and other organs encapsulated in 12 cases(Type III). All the cases underwent adhesiolysis. Intestinal splint was done in 2 patients, gastrostomy in one patient with chronic pyloric obstruction, radical resection of rectal cancer in one patients and ileocolic resection in one patients with Crohn's disease. All patients were healed by surgical operation and confirmed the diagnosis histopathologically. CONCLUSIONS Abdominal cocoon is rare. It is difficult to make a right diagnosis preoperatively. Barium meal X-rays and CT scan are useful methods for its diagnosis. For the treatment, attention should be paid on complete resection of fibrous membrane, adhesiolysis and prevent intestinal obstruction.

Abstract
We hypothesized that small volume enemas accelerate meconium evacuation in very low birth weight (VLBW) infants. In a randomized controlled trial, VLBW infants (n = 81) received either repeated daily small volume enemas if complete spontaneous meconium passage failed within 24 h or no intervention. Small volume enemas did not accelerate complete meconium evacuation, which occurred after 6.0 to 9.6 (95% CI) d in the intervention group and after 7.7 to 11.0 (95% CI) d in the control group. No adverse events were observed. Daily administration of small volume enemas had no effect on total meconium evacuation defined by the time of last meconium passage.

Abstract
Capsule endoscopy is generally a safe procedure with few complications. Clinically significant complications including symptomatic capsule retention and aspiration occur in less than 2% of examinations. There is currently no accepted means of accurately predicting or preventing capsule retention. A modified capsule has recently been developed to determine patency in patients who have possible strictures. Incomplete small bowel examinations occur in 15% of examinations. After risk stratification, various pharmacologic and endoscopic adjuncts can be employed to minimize this complication. Technical complications occur most commonly early in a center's experience and decrease as experience with the device increases. Implanted cardiac devices are no longer an absolute contraindication to the examination but should be conducted after multidisciplinary consultation.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of an adhesion prevention strategy compared to routine care, in which no adhesion prevention measures are taken, through a decision analysis model in the clinical setting of patients undergoing radical hysterectomy and pelvic lymphadenectomy for Stage IB cervical cancer. METHODS A decision analysis model compared two strategies to manage the risk of adhesion-related morbidity following radical hysterectomy for Stage IB cervical cancer: (1) routine care with no adhesion prevention measures, and (2) the intervention strategy with a HA-CMC anti-adhesion barrier. The cost-effectiveness of each strategy was evaluated from the perspective of society and that of a third party payer. RESULTS From the perspective of society, the HA-CMC strategy had an overall cost per patient of $1932 and effectiveness of 7.901 QALYs and dominated the routine care strategy, which had a cost per patient of $3043 and effectiveness of 7.805 QALYs. From the perspective of a third party payer, the HA-CMC strategy had an overall cost per patient of $1247 and effectiveness of 7.987 QALYs and dominated the routine care strategy, which had a cost per patient of $1629 and effectiveness of 7.970 QALYs. A series of one-way sensitivity analyses confirmed the robustness of the model. CONCLUSIONS Under a conservative set of clinical and economic assumptions, an adhesion prevention strategy utilizing a HA-CMC barrier in patients undergoing radical hysterectomy for Stage IB cervical cancer is cost-effective from both the perspective of society as a whole and that of a third party payer.

Abstract
Patients with inoperable colorectal tumours will often require symptomatic relief due to the nature of extensive disease spread or existing co-morbidities. The use of laser treatment for palliation of tumours in the lower gastrointestinal tract has become an attractive treatment option for such patients. This paper presents the results of a retrospective review of 58 case notes in order to determine the effectiveness of laser therapy in palliating symptoms of colorectal tumours. In addition, the paper aims to identify which colorectal symptoms laser is best used to palliate. The study was conducted in a regional coloproctology unit at the Western General Hospital in Edinburgh. The main findings show that 52% (n=30) of patients had successful (complete/good) resolution of symptoms, 36% (n=21) had a poor response and 12% (n=7) had no resolution of symptoms from laser therapy. Of all documented symptoms, this study found that laser is most effective at palliating obstructive symptoms. It also has beneficial application in the palliation of bleeding and mucous discharge. It is less effective for the anal symptoms of tenesmus and pain and for stool related symptoms such as diarrhoea, constipation, frequency and incontinence.
