Abstract
BACKGROUND Adhesion formation after peritoneal surgery is the main cause of postoperative bowel obstruction, infertility, and chronic pelvic pain. In this study, we evaluated the effect of oral ellagic acid on intra-abdominal adhesions caused by gallstones in rats. MATERIALS AND METHODS Forty-one Wistar-albino rats were used. Gallstones were dropped to the right lower quadrant of the abdomen to create adhesions. They were divided into 4 groups; sham-operated, intraperitoneal gallstone, oral ellagic acid (control), and intraperitoneal gallstone+oral ellagic acid. On the postoperative 10th day, relaparotomy was performed, adhesions were evaluated according to four different macroscopic adhesion score systems and adhesion-bearing tissues were examined histopathologically. Samples were graded for inflammation, vascularization, and fibrosis. RESULTS We found that oral administration of ellagic acid lowered all macroscopic adhesion scores. There were significant differences between groups of sham and gallstone; control and gallstone; control and gallstone+oral ellagic acid (P<0.05). CONCLUSION The ellagic acid administered orally at a dose of 100 mg/kg/d significantly inhibited intra-abdominal adhesion formation and no adverse effects were seen between treatments.

Abstract
Background In 2013 Guidelines on diagnosis and management of ASBO have been revised and updated by the WSES Working Group on ASBO to develop current evidence-based algorithms and focus indications and safety of conservative treatment, timing of surgery and indications for laparoscopy. Recommendations In absence of signs of strangulation and history of persistent vomiting or combined CT-scan signs (free fluid, mesenteric edema, small-bowel feces sign, devascularization) patients with partial ASBO can be managed safely with NOM and tube decompression should be attempted. These patients are good candidates for Water-Soluble-Contrast-Medium (WSCM) with both diagnostic and therapeutic purposes. The radiologic appearance of WSCM in the colon within 24 hours from administration predicts resolution. WSCM maybe administered either orally or via NGT both immediately at admission or after failed conservative treatment for 48 hours. The use of WSCM is safe and reduces need for surgery, time to resolution and hospital stay. NOM, in absence of signs of strangulation or peritonitis, can be prolonged up to 72 hours. After 72 hours of NOM without resolution, surgery is recommended. Patients treated non-operatively have shorter hospital stay, but higher recurrence rate and shorter time to re-admission, although the risk of new surgically treated episodes of ASBO is unchanged. Risk factors for recurrences are age <40 years and matted adhesions. WSCM does not decrease recurrence rates or recurrences needing surgery. Open surgery is often used for strangulating ASBO as well as after failed conservative management. In selected patients and with appropriate skills, laparoscopic approach is advisable using open access technique. Access in left upper quadrant or left flank is the safest and only completely obstructing adhesions should be identified and lysed with cold scissors. Laparoscopic adhesiolysis should be attempted preferably if first episode of SBO and/or anticipated single band. A low threshold for open conversion should be maintained. Peritoneal adhesions should be prevented. Hyaluronic acid-carboxycellulose membrane and icodextrin decrease incidence of adhesions. Icodextrin may reduce the risk of re-obstruction. HA cannot reduce need of surgery. Adhesions quantification and scoring maybe useful for achieving standardized assessment of adhesions severity and for further research in diagnosis and treatment of ASBO.

Abstract
BACKGROUND Small bowel obstruction (SBO) is one of the most common emergent complications of general surgery. Intra-abdominal adhesions are the leading cause of SBO. Because surgery can induce new adhesions, non-operative management is preferred in the absence of signs of peritonitis or strangulation. Oral traditional Chinese herbal medicine has long been used as a non-operative therapy to treat adhesive SBO in China. Many controlled trials have been conducted to investigate its therapeutic value in resolving adhesive SBO. OBJECTIVES The aim of this review was to assess the efficacy and safety of oral traditional Chinese medicine (TCM) for adhesive small bowel obstruction. SEARCH METHODS We searched the following databases, without regard to language or publishing restrictions: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Chinese Biomedical Database (CBM), China National Knowledge Infrastructure/Chinese Academic Journals full-text Database (CNKI), and VIP (a full-text database of Chinese journals). The searches were conducted in November 2011. SELECTION CRITERIA Randomised controlled trials and quasi-randomised controlled trials comparing Chinese medicines administered orally, via the gastric canal, or both with a placebo or conventional therapy in participants diagnosed with adhesive SBO were considered. We also considered trials of TCM (oral administration, gastric tube perfusion, or both) plus conventional therapy compared with conventional therapy alone for patients with adhesive SBO. Studies addressing the safety and efficacy of oral traditional Chinese medicinal agents in the treatment of adhesive SBO were also considered. DATA COLLECTION AND ANALYSIS Two authors collected the data independently. We assessed the risk of bias according to the following methodological criteria: random sequence generation, allocation concealment, blinding, incomplete outcome data, selective outcome reporting and other sources of bias. Dichotomous data are presented as risk ratios (OR) and 95% confidence intervals (CI); continuous outcomes are presented as mean differences (MD) and 95% CIs. The data analyses were carried out using Review Manager 5.1. For cases in which necessary information was not reported in the paper, we contacted the primary authors for additional information. MAIN RESULTS Five randomised trials involving 664 participants were analysed. Five different herbal medicines were tested in these trials, including Huo-Xue-Tong-Fu decoction, Xiao-Cheng-Qi-Tang decoction, a combination of Xiao-Cheng-Qi-Tang and Si-Jun-Zi-Tang decoctions, Chang-Nian-Lian-Song-Jie-Tang decoction, and Fufang-Da-Cheng-Qi-Tang decoction. There were variations in the tested herbal compositions and methods of medicine administration. The main outcomes reported in the trials were effects on abdominal pain, abdominal distension, constipation defection, time of first defecation after treatment, and reoperation rate during the course of the disease. Secondary outcomes selected for this review were not available, including complications such as small bowel perfusion (bowel resection, system complications, and other possible complications), length of hospital stay, cost of hospitalisation, and time from admission to surgical intervention. The results of five trials showed that patients receiving TCM combined with conventional therapy seemed to have improved outcomes compared with patients receiving conventional treatment alone (OR 4.24, 95% CI 2.83 to 6.36).However, we cannot conclusively determine the efficacy of TCM in this review due to inadequate reporting, low methodological quality, and the prevalence of various biases in the reviewed studies. Furthermore, because none of the reviewed trials discussed adverse events, we could not evaluate the safety of TCM for adhesive SBO patients. All trials were conducted and published in China. AUTHORS' CONCLUSIONS Although many studies have assessed the use of TCM products for adhesive SBO, most were excluded from this review due to their methodological limitations. This systematic review did not find sufficient evidence to support the objective efficacy and safety of TCM for patients with adhesive SBO. The positive evidence should be interpreted with caution given the insufficient number of studies with large sample sizes, the absence of well-designed, high-quality trials, and the lack of safety information. Therefore, further studies with larger sample sizes and high-quality, randomised, and controlled trials are necessary to produce more accurate and meaningful data on the efficacy of Chinese herbal medicines for adhesive SBO.

Abstract
Background There is no consensus on diagnosis and management of ASBO. Initial conservative management is usually safe, however proper timing for discontinuing non operative treatment is still controversial. Open surgery or laparoscopy are used without standardized indications. Methods A panel of 13 international experts with interest and background in ASBO and peritoneal diseases, participated in a consensus conference during the 1st International Congress of the World Society of Emergency Surgery and 9th Peritoneum and Surgery Society meeting, in Bologna, July 1-3, 2010, for developing evidence-based recommendations for diagnosis and management of ASBO. Whenever was a lack of high-level evidence, the working group formulated guidelines by obtaining consensus. Recommendations In absence of signs of strangulation and history of persistent vomiting or combined CT scan signs (free fluid, mesenteric oedema, small bowel faeces sign, devascularized bowel) patients with partial ASBO can be managed safely with NOM and tube decompression (either with long or NG) should be attempted. These patients are good candidates for Water Soluble Contrast Medium (WSCM) with both diagnostic and therapeutic purposes. The appearance of water-soluble contrast in the colon on X-ray within 24 hours from administration predicts resolution. WSCM may be administered either orally or via NGT (50-150 ml) both immediately at admission or after an initial attempt of conservative treatment of 48 hours. The use of WSCM for ASBO is safe and reduces need for surgery, time to resolution and hospital stay. NOM, in absence of signs of strangulation or peritonitis, can be prolonged up to 72 hours. After 72 hours of NOM without resolution surgery is recommended. Patients treated non-operatively have shorter hospital stay, but higher recurrence rate and shorter time to re-admission, although the risk of new surgically treated episodes of ASBO is unchanged. Risk factors for recurrences are age <40 years and matted adhesions. WSCM does not affect recurrence rates or recurrences needing surgery when compared to traditional conservative treatment. Open surgery is the preferred method for surgical treatment of strangulating ASBO as well as after failed conservative management. In selected patients and with appropriate skills, laparoscopic approach can be attempted using open access technique. Access in the left upper quadrant should be safe. Laparoscopic adhesiolysis should be attempted preferably in case of first episode of SBO and/or anticipated single band. A low threshold for open conversion should be maintained. Peritoneal adhesions should be prevented. Hyaluronic acid-carboxycellulose membrane and icodextrin can reduce incidence of adhesions. Icodextrin may reduce the risk of re-obstruction.

Abstract
BACKGROUND postoperative adhesions are a significant health problem with major implications on quality of life and health care expenses. The purpose of this review was to investigate the efficacy of preventative techniques and adhesion barriers and identify those patients who are most likely to benefit from these strategies. METHODS the National Library of Medicine, Medline, Embase, and Cochrane databases were used to identify articles related to postoperative adhesions. RESULTS ileal pouch-anal anastomosis, open colectomy, and open gynecologic procedures are associated with the highest risk of adhesive small-bowel obstruction (class I evidence). Based on expert opinion (class III evidence) intraoperative preventative principles, such as meticulous hemostasis, avoiding excessive tissue dissection and ischemia, and reducing remaining surgical material have been published. Laparoscopic techniques, with the exception of appendicitis, result in fewer adhesions than open techniques (class I evidence). Available bioabsorbable barriers, such as hyaluronic acid/carboxymethylcellulose and icodextrin 4% solution, have been shown to reduce adhesions (class I evidence). CONCLUSIONS postoperative adhesions are a significant health problem with major implications on quality of life and health care. General intraoperative preventative techniques, laparoscopic techniques, and the use of bioabsorbable mechanical barriers in the appropriate cases reduce the incidence and severity of peritoneal adhesions.

Abstract
BACKGROUND Despite its advantages, iatrogenic gallbladder perforation with resultant spillage of bile and gallstones is not uncommon during laparoscopic cholecystectomy. Although this is not generally considered a significant problem, spilled gallstones may cause problems even years after the operation. Hyaluronic acid has been introduced into clinical practice and successfully used to decrease postoperative adhesions after abdominopelvic surgery. In this study, we investigated the effectiveness of a hyaluronic-acid derivative in preventing complications related to spilled gallstones and bile leakage in an experimental study. METHODS In 60 Wistar-Albino rats, an upper-midline abdominal incision was made, and the rats were divided into 5 groups (n = 12 in each group) as follows: group I = laparotomy alone; group II = laparotomy and intraperitoneal instillation of sterile bile plus gallstones; group III = laparotomy and instillation of infected bile and gallstones; group IV = laparotomy and instillation of sterile bile and gallstones plus hyaluronic acid; and group V = laparotomy and instillation of infected bile and gallstones plus HA. A second-look laparotomy was performed on postoperative day 10 to assess intraperitoneal adhesions and abscesses. Intraperitoneal adhesions were scored, and breaking strengths of gallstones were measured. RESULTS Adhesion scores were significantly higher in groups II and III compared with groups I, IV, and V (P < 0.05). There was a statistically significant decrease in breaking strengths and adhesion scores in groups IV and V compared with groups II and III (P < 0.001). CONCLUSIONS Whether infected or not, spilled gallstones and bile caused postoperative adhesions in this experimental model. An HA derivative significantly prevented postoperative adhesions and decreased breaking strengths. Further clinical studies are needed to validate these findings.

Abstract
BACKGROUND In the diagnosis and treatment of biliary disorders, establishing percutaneous transhepatic biliary drainage (PTBD) is an invasive procedure that can potentially lead to infectious complications in both the short and long-term. We therefore prospectively analysed the time course and spectrum of biliary bacteria in patients undergoing PTBD. METHODS Forty-nine patients (19 F, 30 M; mean age 64 years) with malignant (65%) or benign (35%) biliary disorders were included, 20 of whom had a newly established PTBD (group A), while the remaining 29 had already had their PTBD in situ (group B) for a mean of 8 months. Bacteriological analyses of bile and blood were carried out, and clinical symptoms and laboratory values were obtained. RESULTS Biliary bacteria were found in 60% of cases during the initial PTBD placement, and 24 h later this rate had already increased to 85%; two or more microorganisms were found in 40% initially and in 70% after a few days. At later PTBD exchanges, bacteriobilia was found in 100%, with all patients harbouring multiple organisms. Whereas the initial spectrum was mixed, Escherichia coli and enterococci (97% each), Klebsiella (73%) and Bacteroides species (37%) later predominated; Candida increased initially from 15% to 80%, but later decreased to 30%. Clinical signs of cholangitis were observed in 30% initially (no sepsis), but decreased to 6% at later exchanges. CONCLUSIONS Bacteriobilia is initially a frequent, and later a regular, event in PTBD; however, clinically significant complications are rare during the long-term course and limited to the initial, more invasive, phase of PTBD. A knowledge of the bacterial spectrum is important for selecting appropriate antibiotic coverage if complications arise and/or major interventions such as surgery are planned.
