World J Gastroenterol 2013; 19:7138-7145. [PMID: 24222958 PMCID: PMC3819550 DOI: 10.3748/wjg.v19.i41.7138] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2013] [Revised: 05/22/2013] [Accepted: 08/06/2013] [Indexed: 02/07/2023] Open
Abstract
AIM: To investigate whether predicting patients that might be at a higher risk for complications might serve to improve the selection of patients undergoing colonic stenting.
METHODS: A retrospective review of consecutive patients who underwent an attempted self-expandable metal stent (SEMS) insertion for malignant colonic obstruction between November 2006 and March 2013. All patients were either referred for preoperative colonic decompression with the intent of a single surgical procedure, or for palliation of the malignant colorectal obstruction for unresectable cancer. Fisher’s test or χ2 test was performed on categorical variables, and the t test for continuous variables. Univariable and multivariable logistic regression were used to examine the association between independent variables and the presence of complications from SEMS insertion.
RESULTS: SEMS insertion was attempted in 73 patients. Males comprised 55.71% and the mean age was 67.41 ± 12.41 years. Of these, 65.15% underwent subsequent surgery, while 34.85% received SEMS as palliation for advanced disease. Extracolonic tumors were only 4.76%. The majority of patients had stage IV disease (63.83%), while the remainder had stage III (36.17%). SEMS were successfully inserted in 93.85% (95%CI: 87.85%-99.85%). Perforations occurred in 4.10%, SEMS migration in 8.21%, and stent re-occlusion from ingrowth occurred in 2.74% of patients. The mean duration of follow up for the patients was 13.52 ± 17.48 mo (range 0-73 mo). None of the variables: age, sex, time between the onset of symptoms to SEMS insertion, time between SEMS insertion and surgery, length of the stenosis, location of the stenosis, albumin level, or receiving neoadjuvant chemotherapy, could predict the development of complications from either SEMS insertion nor prolonged survival.
CONCLUSION: None of the variables could predict the development of complications or survival. Further studies are required to identify patients who would benefit the most from SEMS.

Crit Rev Oncol Hematol 2013; 88:387-403. [PMID: 23845505 DOI: 10.1016/j.critrevonc.2013.06.006] [Citation(s) in RCA: 62] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2013] [Revised: 05/25/2013] [Accepted: 06/13/2013] [Indexed: 02/06/2023] Open
Abstract
The best approach to resolve colonic obstruction in patients with left-sided colon cancer is not established. In this meta-analysis the efficacy of stenting as bridge-to-surgery was compared to emergency surgery for the management of left-sided colonic obstruction. Fourteen studies (randomized and non controlled studies) were identified, including 405 patients in the stent group and 471 in the emergency group. The difference between proportions was evaluated as effect size (ESi). There was large heterogeneity among the studies. Stenting offered advantages over emergency surgery in terms of increase in primary anastomosis (ES=25.1%, p<0.001), successful primary anastomosis (ES=23.7%, p<0.001), reduction of stoma creation (ES=-27.1%, p=0.03), infections (ES=-7.9%, p=0.006) and other morbidities (ES=-13.4%, p<0.001). The interventions were similar in regards to length of hospitalization, preoperative mortality and long-term survival.

SEMS vs cSEMS in duodenal and small bowel obstruction: High risk of migration in the covered stent group. World J Gastroenterol 2013; 19:6199-6206.

Abstract
AIM: To compare clinical success and complications of uncovered self-expanding metal stents (SEMS) vs covered SEMS (cSEMS) in obstruction of the small bowel.
METHODS: Technical success, complications and outcome of endoscopic SEMS or cSEMS placement in tumor related obstruction of the duodenum or jejunum were retrospectively assessed. The primary end points were rates of stent migration and overgrowth. Secondary end points were the effect of concomitant biliary drainage on migration rate and overall survival. The data was analyzed according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines.
RESULTS: Thirty-two SEMS were implanted in 20 patients. In all patients, endoscopic stent implantation was successful. Stent migration was observed in 9 of 16 cSEMS (56%) in comparison to 0/16 SEMS (0%) implantations (P = 0.002). Stent overgrowth did not significantly differ between the two stent types (SEMS: 3/16, 19%; cSEMS: 2/16, 13%). One cSEMS dislodged and had to be recovered from the jejunum by way of laparotomy. Time until migration between SEMS and cSEMS in patients with and without concomitant biliary stents did not significantly differ (HR = 1.530, 95%CI 0.731-6.306; P = 0.556). The mean follow-up was 57 ± 71 d (range: 1-275 d).
CONCLUSION: SEMS and cSEMS placement is safe in small bowel tumor obstruction. However, cSEMS is accompanied with a high rate of migration in comparison to uncovered SEMS.

Abstract
AIM: To assess whole-body fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the management of small bowel obstructions (SBOs) secondary to gastric cancer and its role in treatment strategies.
METHODS: The medical records of all of the patients who were admitted for an intestinal obstruction after curative resection for gastric cancer were retrospectively reviewed. PET/CT was performed before a clinical treatment strategy was established for each patient. The patients were divided into 2 groups: patients with no evidence of a tumor recurrence and patients with evidence of a tumor recurrence. Tumor recurrences included a local recurrence, peritoneal carcinomatosis or distant metastases. The primary endpoint was the 1-year survival rate, and other variables included patient demographics, the length of hospital stay, complications, and mortality.
RESULTS: The median time between a diagnosis of gastric cancer and the detection of a SBO was 1.4 years. Overall, 31 of 65 patients (47.7%) had evidence of a tumor recurrence on the PET/CT scan, which was the only factor that was associated with poor survival. Open and close surgery was the main type of surgical procedure reported for the patients with tumor recurrences. R0 resections were performed in 2 patients, including 1 who underwent combined adjacent organ resection. In the group with no evidence of a tumor recurrence on PET/CT, bowel resections were performed in 7 patients, adhesiolysis was performed in 7 patients, and a bypass was performed in 1 patient. The 1-year survival curves according to PET/CT evidence of a tumor recurrence vs no PET/CT evidence of a tumor recurrence were significantly different, and the 1-year survival rates were 8.8% vs 93.5%, respectively. There were no significant differences (P = 0.71) in the 1-year survival rates based on surgical vs nonsurgical management (0% with nonoperative treatment vs 20% after exploratory laparotomy).
CONCLUSION: 18F-FDG PET/CT can be used to identify the causes of bowel obstructions in patients with a history of gastric cancer, and this method is useful for planning the surgical management of these patients.

Abstract
BACKGROUND Patients with stage IV cancer and bowel obstruction (BO) present a complicated management problem. We sought to determine if specific parameters could predict outcome after surgery. METHODS Records of patients with stage IV cancer and BO treated from 1991 to 2008 were reviewed. For surgical patients, 30-day morbidity and 90-day mortality were assessed using exact multivariable logistic regression methods. RESULTS Of 198 patients, 132 (66.7%) underwent surgery, 66 medical treatment alone, and demographics were similar. A total of 41 patients (20.7%) were diagnosed with stage IV cancer and BO synchronously, all treated surgically; the remaining presented metachronously. Medically managed patients were more likely to have received chemotherapy in the 30 days prior to BO (45 of 66 [68.2%] vs 40 of 132 [30.3%], p < .01). In the surgical group, 30-day morbidity was 35.6%, while 90-day mortality was 42.3%. Median overall survival for synchronous patients was 14.1 months (95% confidence interval [95% CI] 7.6-23.2), and 3.7 months (95% CI 2.5-5.2) and 3.6 months (95% CI 1.5-5.2) for metachronous patients treated surgically and medically, respectively. A multivariate model for 90-day surgical mortality identified low serum albumin, metachronous presentation, and ECOG > 1 as predictors of death (p < .05). A model for 30-day surgical morbidity yielded low hematocrit as a predictive factor (p < .05). CONCLUSIONS This cohort identifies characteristics indicative of morbidity and mortality in stage IV cancer and BO. Low serum albumin, ECOG > 1, and metachronous presentation predicted for 90-day surgical mortality. These data suggest factors that can be used to frame treatment discussion plans with patients.

Abstract
Controversy exists but most surgeons agree that surgical treatment for failed conservative management of adhesion-related small bowel obstruction (SBO) should be within 48 hours. However, many find themselves delaying definitive treatment in the hopes of resolution. Our aim was to determine what impact timing has on surgical outcomes of SBO. A retrospective review of all consecutive patients surgically treated for adhesion-related SBO was performed from January 2001 to August 2006. Study groups included patients treated emergently (less than 6 hours), expeditiously (6 to 48 hours), and delayed (greater than 48 hours). Laparoscopic, open, and converted treatment types were controlled for as confounding variables using analysis of variance. Outcome measures were return of bowel function after surgery (RBF), length of stay after surgery (LOS), and morbidity. There were 27 emergencies, 30 treated expeditiously, and 34 delayed. Groups were matched in age and gender. RBF after surgery was significantly longer for those delayed in treatment compared with those treated expeditiously (greater than 48 hours = 7.4 days vs less than 6 hours = 7.6 and 6 to 48 hours = 5.4; P < .05) as well as LOS after surgery (greater than 48 hours = 12.3 days vs less than 6 hours = 10.1 and 6 to 48 hours = 7.6; P < 0.05). Patients treated with laparoscopy within 6 to 48 hours had a significantly shorter RBF and LOS than any other combination of timing and treatment. Postoperative morbidity was higher in the delayed group (79%) than the other groups (44% emergent and 40% expeditious) (P < 0.05). There was one death in the delayed group. Delaying surgical treatment beyond 48 hours for SBO is common and results in worse outcomes and longer LOS. Laparoscopic treatment within 48 hours is superior to open treatment.

Abstract
INTRODUCTION SCC have an incidence of 1,8% up to 12,4% and could have more simultaneous localizations. MATERIAL AND METHOD Between January 2004 and January 2011, 214 patients with CRC have been operated on in our ward; from those, eight patients had multiple colorectal neoplasms. RESULTS The majority of SCC (six cases) was hospitalized under emergency status, with incomplete or complete bowel obstruction through colonic obstructive tumour. The favourite localizations were on the sigmoid (six tumours) and the transverse colon (four tumours). The diagnosis was preoperatively assessed in three cases by colonoscopy and barium enema, intraoperative in four cases, postoperative in one case. Curative operations were performed in five cases and palliative operations in three. Immediate postsurgical evolution was good, long time evolution was marked by the complications of the primary disease. Out of five patients that were long term monitored, three have a five year survival, one has survived for three years and one deceased within a nine month period after surgery, with multiple metastases. CONCLUSIONS Preoperative diagnosis of synchronous lesions can be difficult (emergency hospitalized patient, incomplete bowel preparation, bowel obstruction or intestinal bleeding) and the colonoscopy exam can be incomplete. Rigorous intraoperative colonic examination is necessary in order to diagnose synchronous lesions and avoid surgical reintervention.

Abstract
This study describes the outcome and complications in horses that had a closed, one-stage, stapled, functional, end-to-end (COSFE) jejuno-ileal anastomosis (JIA) following resection of compromised small intestine. Medical records were reviewed to identify all horses that had a COSFE JIA performed during exploratory laparotomy and to determine post-operative complications and final outcome. All 5 horses that were identified had successful COSFE JIA with resection of various amounts of distal jejunum and proximal ileum. Post-operative ileus occurred in 1 of the 5 horses. All horses survived at least 1 year after surgery. The survival times and incidence of post-operative ileus compared favorably with published results for other types of small intestinal resection and anastomoses. A COSFE JIA is a viable surgical procedure to correct lesions of the distal jejunum and proximal ileum.

Abstract
OBJECTIVE To explore the surgical approaches and clinical outcomes of chronic radiation intestinal injury (CRII). METHODS From January 1, 2001 to December 31, 2010, at Department of Surgery, Nanjing General Hospital of Nanjing Command a consecutive series of 206 CRII patients undergoing surgical interventions was reviewed retrospectively. There were 64 males and 142 females with an age range of (50 ± 11) years old. The indications, surgical approaches, surgical complications and mortality were analyzed. RESULTS 206 CRII patients received 229 surgical treatment, 31 patients underwent two or more operations. The course of surgical interventions included intestinal obstruction (n = 142), intestinal fistula (n = 56), proctitis (n = 12), bleeding (n = 6) and others (n = 13). They underwent 229 laparotomies including intestinal resection and primary anastomosis (n = 142), intestinal resection and enterostomy (n = 57), exclusion of radiation-related gastrointestinal diseases (n = 14) and other procedures (n = 16). The occurrence rate of postoperative intestinal complications was 25.7% (53/206). Five patients (2.4%) died within the postoperative 28 days. CONCLUSION Surgery is often required for patients with chronic radiation-induced intestinal obstruction, fistula, hemorrhage and perforation, etc. Resection and primary anastomosis with undamaged segments may be performed safely in selected patients. And a judicious use of stoma can reduce the rates of major surgical mortality and morbidity.

Abstract
The results of surgical treatment of 517 patients with intestinal obstruction were analyzed. All patients had wide small bowel resections with primary anastomoses. The study demonstrated that the main survival predictive factors were: the age, general clinical condition, time before the operation, type of the anastomosis, resection volume of the adducent bowel loop and systemic complications. The increasing of the resectional volume and the use of "end-to-end" anastomoses lead to the statistically significant improvement of the treatment results.

Abstract
BACKGROUND Colorectal cancer is one of the most common cancer in the western world. Acute colonic obstruction is one of the common presentations of colon cancer. Emergency surgical decompression is the traditional treatment of choice but is associated with high morbidity and mortality. In recent years colonic stents have been used to relieve the obstruction. OBJECTIVES The aim was to compare the colonic stenting versus emergency surgical decompression with regards to benefits and risks. SEARCH METHODS Searches were carried out May 2010 in the Cochrane Colorectal Cancer Specialised Register, the Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Ovid EMBASE and Ovid CINAHL. SELECTION CRITERIA Randomised clinical trials comparing colonic stenting versus surgical decompression for obstructing colorectal cancers were considered for inclusion. DATA COLLECTION AND ANALYSIS Data on the characteristics of the trial, methodological quality of the trials, mortality, morbidity, technical and clinical success rate, operating time, hospital stay and other measured secondary outcomes from each trial were collected. And the data were analysed with both the fixed-effect and the random-effects models using RevMan Analysis. For each outcome, odds ratio (OR) with 95% confidence intervals (CI) based on available data analysis was calculated. MAIN RESULTS Five randomised trials were identified with a total of 207 participants, 102 to colorectal stenting and 105 to emergency surgery. There was statistically significant higher clinical success rate in the emergency surgery group. The average time of clinical relief of obstruction was 0.66 day in the colonic stent group and was 3.55 days in the emergency surgery group. The stent insertion was successful in 86.02% of attempted stent placements. There was no statistically significant difference in the 30-day mortality between two groups. The 30 day mortality rate was similar, 2.3% in both groups. The stent related perforation rate was 5.88%. The stent migration rate was 2.13%. The stent obstruction rate was 2.13%. There was no statistically significant difference in overall complication rate in both groups. The complication rate was 39.22% in the colonic stent group and was 45.71% in the emergency surgery group. The mean hospital stay was 11.53 days in the colonic stent group and was 17.15 days in the emergency surgery group. The mean procedure/operating time was 113.93 minutes in the colonic stent group compared to 143.85 minutes in the emergency surgery group. The median blood loss was 50 ml in the colonic stent group and 350 ml in the emergency surgery group. AUTHORS' CONCLUSIONS The use of colonic stent in malignant colorectal obstruction seems to have no advantage over emergency surgery. The clinical success rate was statistically higher in emergency surgery group. However, use of colorectal stents seems to be as safe in the malignant colorectal obstruction as the emergency surgery with no statistically significant difference in the mortality and morbidity. Colorectal stents are associated with acceptable stent perforation, migration and obstruction rates. The advantages of colorectal stent includes shorter hospital stay and procedure time and less blood loss. However, due to the variability in the sample size and trial designs in the included studies, further randomised trials with bigger sample size and well defined trial design are needed to achieve the robust evidence.

Abstract
AIM Colonic SEMS are increasing used in the management of acute large bowel obstruction, both as a bridge to surgery and as a definitive palliative measure in patients unfit for surgery. We describe our experience from a New Zealand hospital and compare our data with that already published in literature. METHODS In this retrospective 4-year study, data was collected from the case notes of 28 consecutive patients with acute large bowel obstruction referred for colonic SEMS. Uncovered Boston Scientific colonic SEMS were placed endoscopically under fluoroscopic guidance. Technical success was considered as correct placement of stent after deployment and clinical success as the passage of flatus and faeces after stent insertion. Data was analysed using descriptive statistics. RESULTS Our technical and clinical success rates were 90% and 88% respectively. The procedure was palliative in 15 patients and as a bridge to elective surgery in 13 cases. Procedure-related mortality was 7%. It was because of one early and one late perforation. The average length of stay post procedure was 2 days. Mean survival post stent insertion in the palliative group was 2.4 months and for those with a bridge to surgery was 14 months. CONCLUSION n Our results support the data published from international centres in terms of deployment of SEMS in patients with acute large bowel obstruction, both as a bridge to surgery and as a definitive palliative measure.

Abstract
BACKGROUND Decision-making for surgical palliation remains one of the most challenging clinical scenarios. We investigated the optimal indications for surgical palliation in advanced gastric cancer (AGC) patients presenting with gastrointestinal (GI) obstruction. METHODS A retrospective analysis was performed on 53 consecutive patients who underwent surgical palliation for GI obstruction caused by AGC between 2000 and 2007 at Osaka National Hospital. The clinical course of each patient was followed until death. Postoperative improvement of oral intake, achievement of hospital discharge, and implementation of chemotherapy in each patient were documented and used as a triad to assess the quality of life (QOL). Prognostic factors for overall survival were investigated by univariate and multivariate analyses. In addition, postoperative morbidity and mortality rates were recorded. RESULTS Of the entire patient cohort, 64% demonstrated a QOL improvement by having achieved the triad. Performance status (PS) of 1 or less was the only significant predictive factor for QOL improvement. The median survival time (MST) of the whole patient cohort following surgical palliation was 161 days, while the MSTs of patients fulfilling the triad and of those failing to achieve the triad were 253 and 60 days, respectively, with a significant difference between them (P < 0.0001). PS of 1 or less (hazard ratio 0.265, P = 0.0008) and recurrent disease (hazard ratio 0.394, P = 0.043) were identified as significant independent prognostic factors for longer survival on multivariate analysis. Overall morbidity and 30-day postoperative mortality rates were 24.5% (13 patients) and 7.5% (4 patients) respectively. CONCLUSIONS In AGC patients presenting with GI obstruction, surgical palliation was beneficial in patients with PS of 0-1 and those with recurrent disease, in terms of improved QOL and prolonged survival, with acceptable operative morbidity and mortality rates.

Abstract
BACKGROUND The use of a colonic stent as a bridge to surgery aims to provide patients with elective one-stage surgical resection while reducing stoma creation and postoperative complications. This study used meta-analytic techniques to compare the outcomes of stent use as a bridge to surgery and emergency surgery in the management of obstructive colorectal cancer. METHODS A literature search of Medline, Embase, Cochrane controlled trials registry, and the Chinese Biomedical Literature Database was performed on all studies comparing stent as a bridge to surgery and emergency surgery for obstructive colorectal cancer. A meta-analysis of the included studies was carried out to identify the differences in outcomes between the two procedures. RESULTS Eight studies matched the criteria for inclusion and reported on the outcomes of 601 patients, of whom 232 (38.6%) underwent stent insertion and 369 (61.4%) underwent emergency surgery. Fewer patients in the stent group needed intensive care (risk ratio [RR], 0.42; 95% confidence interval [CI], 0.19-0.93; p = 0.03) and stoma creation (RR, 0.70; 95% CI, 0.50-0.99; p = 0.04). The primary anastomosis rate in the stent group was higher (RR, 1.62; 95% CI, 1.21-2.16; p = 0.001). Overall complications (RR, 0.42; 95% CI, 0.24-0.71; p = 0.001), including anastomotic leakage (RR, 0.31; 95% CI, 0.14-0.69; p = 0.004), were reduced by stent insertion. Stent placement before elective surgery did not adversely affect mortality and long-term survival. CONCLUSIONS The use of a stent as a bridge to surgery for obstructive left-sided colorectal cancer could increase the chance of primary anastomosis and reduce the need for stoma creation and postprocedural complications. Stent insertion before subsequent surgery has no effect on perioperative mortality and long-term survival.

Abstract
INTRODUCTION Despite significant progress, the management of acute colonic obstruction still remains a challenging problem. The purpose of this study was represented by the evaluation of the clinical results of different techniques of resection for malignant colorectal (primary or staged) obstruction. METHODS We performed a non-randomized clinical study. 590 patients with malignant colorectal occlusion who underwent surgery treatment an 3rd Surgical Clinic Cluj-Napoca between 1996-2005 were included. RESULTS Patients with large bowel obstruction underwent one-stage primary resection with anastomosis in 267 cases or staged interventions in 323 cases. The groups were matched in: age, sex, comorbidities, tumor staging, serum preoperative levels of hemoglobin and proteins. The analysis of mortality and morbidity following surgical treatment for large bowel obstruction returned no significant difference among the two groups (p > 0.05). Moreover, the presented results showed a higher incidence of mortality (11.45% vs 9.33 %), morbidity (25.38% vs 14.6%) and increased hospitalization period (p = 0.029) among the patients that undergone seriate resections. CONCLUSIONS One stage primary resections with anastomosis of the large bowel can be performed safely in case of emergency whenever patient comorbidities and local conditions do not stand as major restrictions.

Abstract
AIMS To retrospectively evaluate the medical and surgical records of horses with acute small intestinal obstructions associated with Parascaris equorum infection; to describe the gastrointestinal lesions; and to determine the outcome of cases with such lesions. METHODS Records of 25 horses with acute small intestinal obstruction associated with P. equorum between 1985 and 2004 were reviewed to determine signalment, history, physical examination, surgical or post-mortem findings, and outcome. RESULTS All horses except one were less than 12 months old. Standardbreds were over-represented in the population studied. Sixteen horses (72%) had been administered anthelmintics, including pyrantel (n=8), ivermectin (n=7), and trichlorphon (n=1), within 24 h prior to the onset of colic. Of the 25 cases reviewed, 16 had simple obstructive ascarid impactions (SOAIs), and nine had complicated obstructive ascarid impaction (COAI) including volvulus (n=6) or intussusception (n=3), both concurrent with ascarid impaction of the small intestine. Short-term survival (discharge from hospital) occurred in 79% of horses treated for SOAI, and was 64% for all horses. Long-term survival (>1 year) occurred in 33% of horses with SOAI, and the overall long-term survival was 27% for all horses. Formation of adhesions was the most frequent finding associated with death for horses that did not survive long-term. CONCLUSIONS AND CLINICAL RELEVANCE The incidence of anthelmintic treatment within 24 h of the onset of colic in this study population (72%) was higher than that previously reported. Resistance of P. equorum to ivermectin recently reported in Ontario may be associated with increased ascarid burdens, predisposing horses to ascarid impaction. The long-term survival of these horses was better than that reported previously.

Abstract
CONTEXT The management of malignant bowel obstruction (MBO) is often challenging and frequently involves multiple treatment modalities, including chemotherapy, surgery, stenting, and symptomatic medical management. OBJECTIVES To describe the natural history of patients diagnosed with MBO who were admitted to a tertiary level hospital and followed by a multidisciplinary team that included medical oncologists, surgical oncologists, and palliative care specialists. METHODS Thirty-five patients admitted under medical or surgical oncology with a diagnosis of MBO were followed over a two-year period or until the time of death. Primary malignancies included colon, rectum, pancreas, biliary, breast, bladder, carcinoid, renal cell, gastric, lung, and melanoma. Clinical outcomes of interest included survival, percentage of patients receiving surgery and/or chemotherapy, total parenteral nutrition (TPN), insertion of venting gastrostomy tube, disposition, and rates of readmission to hospital. RESULTS Median survival was 80 days and three patients were alive at the time of study closure. At our center, 34% of patients underwent surgical intervention, 37% received at least one dose of post-MBO chemotherapy, and 43% received TPN. There was a cohort of patients (17%) who were alive at one year. CONCLUSION Interventions such as chemotherapy and TPN may be appropriate in a carefully selected subgroup of patients. A collaborative approach is required for the optimal clinical management and palliation of MBO.

Thirty-day mortality and late survival with reinterventions and readmissions after open and endovascular aortic aneurysm repair in Medicare beneficiaries. J Vasc Surg 2010; 53:6-12,13.e1.

Abstract
OBJECTIVES Late survival is similar after open and endovascular abdominal aortic aneurysm (AAA) repair (EVAR), despite a perioperative benefit with EVAR. AAA-related reinterventions are more common after EVAR, whereas laparotomy-related reinterventions are more common after open repair. The effect of reinterventions on survival, however, is unknown. We therefore evaluated the rate of reinterventions and readmission after initial AAA repair, 30-day mortality, and the effect on long-term survival. METHODS We identified AAA-related and laparotomy-related reinterventions for propensity score-matched cohorts of 45,652 Medicare beneficiaries undergoing EVAR and open repair from 2001 to 2004. Follow-up was up to 6 years. Hospitalizations for ruptured AAA without repair and for bowel obstruction or ventral hernia without abdominal surgery were also recorded. Event rates were calculated per year and are presented through 6 years of follow-up as events per 100 person-years. Thirty-day mortality was calculated for each reintervention or readmission. RESULTS Through 6 years, overall reinterventions or readmissions were similar between repair methods but slightly more common after EVAR (7.6 vs 7.0/100 person-years; relative risk [RR], 1.1; P < .001). Overall 30-day mortality with any reintervention or readmission was 9.1%. EVAR patients had more ruptures (0.50 vs 0.09 [RR, 5.7; P < .001]), with a mortality of 28%, but these were uncommon. EVAR patients also had more AAA-related reinterventions through 6 years (3.7 vs 0.9 [RR, 4.0; P < .001]; mortality, 5.6%), most of which were minor endovascular reinterventions (2.4 vs 0.2 [RR, 11.4; P < .001]), with a 30-day mortality of 3.0%. However, minor open (0.8 vs 0.5 [RR, 1.4; P < .001]; mortality, 6.9%) and major reinterventions (0.4 vs 0.2 [RR, 2.4; P < .001]; mortality, 12.1%) were also more common after EVAR than open repair. Conversely, EVAR patients had fewer laparotomy-related reinterventions than open patients (1.4 vs 3.0 [RR, 0.5; P < .001]; mortality, 8.1%) and readmissions without surgery (2.0 vs 2.7 [RR, 0.7; P < .001]; mortality 10.9%). Overall, reinterventions or readmission accounted for 9.6% of all EVAR deaths and 7.6% of all open repair deaths in the follow-up period (P < .001). CONCLUSIONS Reintervention and readmission are slightly higher after EVAR. Survival is negatively affected by reintervention or readmission after EVAR and open surgery, which likely contributes to the erosion of the survival benefit of EVAR over time.

Abstract
We compared patients with small bowel obstruction (SBO) admitted through the emergency department to the surgical service (SS) with those admitted to the medical service (MS) with respect to outcomes and healthcare cost. We conducted a retrospective analysis of our SBO database comparing 482 patients admitted to SS and 153 patients admitted to MS at a single institution over a 5-year period (January 2003 to December 2007). Study outcomes included length of hospital stay (LOS), time to surgery (TTS), hospital charges, incidence of bowel resection, and mortality. Both groups were comparable for age, gender, and race. The SS group had a shorter LOS (6.1 vs. 7.5 days; P = 0.01), less hospital charges ($29,549 vs. $35,789; P = 0.06), shorter TTS (log rank comparison; P = 0.006), and less mortality (eight [1.66%] vs. six [3.92]; P = 0.11). The SS group had more bowel resections (13.1 vs. 5.2%; P = 0.007). Coronary artery disease (CAD), acute renal failure (ARF), admission to SS, and female gender were significant predictors of bowel resection. CAD and ARF were significant predictors of mortality. Two hundred forty-four patients required operative intervention (surgery operative subgroup [SOS] 210 [43.6%], medicine operative subgroup [MOS] 34 [22.2%]). SOS and MOS were comparable for gender and race. SOS had shorter LOS (9.1 vs. 12.3 days; P = 0.02), less hospital charges ($46,258 vs. $62,778, P = 0.05), and less mortality (eight [3.81%] vs. four [11.76%]; P = 0.07). Bowel resection was comparable (SOS 30% vs. MOS 23%; P = 0.44). CAD and congestive heart failure (CHF) were significant predictors of bowel resection, whereas CAD was the only significant predictor of mortality in this subgroup. We recommend that patients with SBO be admitted to SS because this might translate to shorter LOS, earlier operative intervention, and reduced healthcare use direct cost. Bowel resection and death are more likely to occur in patients with comorbidities like CHF, CAD, diabetes mellitus, and ARF.

Abstract
REASONS FOR PERFORMING STUDY Small intestinal resection and anastomosis is a relatively common procedure in equine surgical practice. This study was designed to test objectively the subjective opinions of surgeons at the Liphook Equine Hospital that an end-to-end jejuno-ileal anastomosis (JIA) is an effective and clinically justifiable procedure, contrary to conventional recommendations. HYPOTHESIS An end-to-end JIA carries no greater risk of morbidity and mortality than an end-to-end jejunojejunal anastomosis (JJA). METHODS A retrospective observational study was performed on a population of 100 horses that had undergone small intestinal resection and end-to-end anastomosis. Two groups were identified; Group 1 (n = 30) had undergone an end-to- end JIA and Group 2 (n = 70) an end-to-end JJA. The 2 populations were tested for pre- and intraoperative comparability and for their equivalence of outcomes. RESULTS The 2 populations were comparable in terms of their distributions of preoperative parameters and type of lesion present. The observations used as outcome parameters (incidence risk of post operative colic, incidence risk of post operative ileus, duration of post operative ileus, rates of functioning original anastomoses at the time of discharge and at 12 months, survival rates at 6 months and 12 months) were equivalent between the 2 groups. CONCLUSION End-to-end JIA carries no greater risk of morbidity and mortality than an end-to-end JJA. POTENTIAL RELEVANCE Surgeons faced with strangulating obstructions involving the jejuno-ileal junction in which there remains an accessible length of viable terminal ileum may reasonably perform an end-to-end JIA. This has the potentially significant advantage over a jejunocaecal anastomosis of preserving more anatomical and physiological normality to the intestinal tract. The study was, however, relatively small for an equivalence study and greater confidence would be gained with higher numbers.

Abstract
REASONS FOR PERFORMING STUDY Epiploic foramen entrapment (EFE) is one of the more common causes of colic in horses, but recent reports suggest a poor prognosis after surgical treatment. HYPOTHESIS That EFE has a good prognosis compared with other small intestinal strangulating lesions. METHODS Surgical findings, surgical procedures and short-term outcome were recorded for 157 horses that underwent surgery for strangulating lesions of the small intestine at the University of Illinois from 1994 to 2003. Horses were assigned to 3 groups for comparison; those with EFE, strangulation by lipoma and miscellaneous strangulating lesions. A logistic regression model and Monte Carlo tests of the binomial proportions were used to examine survival rates. The Kruskal-Wallis test was used to determine differences in usage of surgical treatments. Measurements of length and viability indices were analysed using a one-way analysis of variance followed by Tukey's HSD test, and viability scores were analysed using an exact Kruskal-Wallis test. Significance was set at P < 0.05. RESULTS Horses with EFE were significantly more likely to be discharged (95%) than those with the other conditions (P < 0.05). The proportion of horses with ileal involvement was greater in horses with EFE than in the other 2 groups (P < 0.05), although this did not affect outcome. The distributions of viability grades for EFE and lipoma differed significantly (P < 0.05). CONCLUSIONS The prognosis for horses that had surgery at this hospital for EFE was better than for those with the other conditions, although the greater proportion of horses with EFE with ileal involvement could influence outcome. Therefore, surgeons must consider ways of improving jejunocaecostomy and determining when bowel is viable, the latter to avoid jejunocaecostomy.

Abstract
The results of the colon cancer treatment with the use of laparoscopic surgery and different radiotherapy regimens were compared. 75 patients were observed. The main group consisted of 38 patients, who were operated on laparoscopically and had received neoadjuvant radiotherapy course. The control group consisted of 37 patients. The were operated on with the use of "open" techniques, had been colostomized before radical surgery and received adjuvant radiotherapy course. Laparoscopic technologies allowed to improve immediate results of the treatment and to decrease the complication rate from 17.2 to 8.2%. Neoadjuvant radiotherapy allowed to decrease the rate of local cancer recurrence from 28.8 to 12.55%.

Abstract
OBJECTIVE To determine the natural history and treatment of high-grade small bowel obstruction (HGSBO). Small bowel obstruction is a frequent complication of abdominal surgery. Complete and strangulating obstructions are managed operatively while partial obstructions receive a trial of nonoperative therapy. The management and outcome of patients with HGSBO diagnosed by computed tomography (CT) has not been examined. DESIGN Retrospective medical record review. Outcomes for nonoperative vs operative management were analyzed using Fisher exact and log-rank tests. SETTING Tertiary care referral center. PATIENTS One thousand five hundred sixty-eight consecutive patients admitted from the emergency department with a diagnosis of small bowel obstruction between 2000 and 2005 by CT criteria. MAIN OUTCOME MEASURES Recurrence of symptoms and complications. RESULTS One hundred forty-five patients (9%) with HGSBO were identified, with 88% follow-up (median, 332 days; range, 4-2067 days). Sixty-six (46%) were successfully managed nonoperatively while 79 (54%) required an operation. Length of stay and complications were significantly increased in the operative group (4.7 days vs 10.8 days and 3% vs 23%; P < .001). Nonoperative management was associated with a higher recurrence rate (24% vs 9%; P < .005) and shorter time to recurrence (39 days vs 105 days; P < .005) compared with operative intervention. Computed tomography signs of ischemia, admission laboratory results, and presence of cancer or inflammatory bowel disease were not predictive of an operation. CONCLUSIONS Patients with HGSBO by CT can be managed safely with nonoperative therapy; however, they have a significantly higher rate of recurrence requiring readmission or operation within 5 years.

Abstract
This study was undertaken to evaluate the clinical characteristics, perioperative features, and outcome of congenital intrinsic intestinal obstruction in a developing Caribbean country for comparison with previous literature reports. This study included retrospective data collection on all infants referred to the hospital with a diagnosis of congenital intrinsic bowel obstruction during the period 1999-2006. Data studied were demographic features, perioperative details, surgical procedures performed, postoperative course, and early outcome. Twenty-two infants were treated, with an incidence of 3.14 per 10,000 live births. Duodenal outnumbered jejuno-ileal lesions by 1.5 to 1. Complications occurred in 68.2% of cases, and the mortality rate was 27.3%. Lower gestational age, a high leukocyte count, and more distal small bowel obstruction were significantly associated with mortality. Improvement in the outcome of surgical treatment of this problem in this population requires more effective perioperative management of prematurity and sepsis.

Abstract
BACKGROUND/AIMS The objective of this study is to clarify the pathological condition and treatment strategy of lethal obstructive colitis (LOC), which is defined as obstructive colitis with severe shock or septic shock. METHODOLOGY We examined 5 patients with LOC (colorectal cancer or suspected in 2, fecal impaction in 2, and volvulus in 1) and evaluated their pathophysiology and management strategy from their medical records. RESULTS Emergency operations were performed within 150 minutes from arrival in all cases. Three were saved by repeat operations and 2 died. The systolic pressure of both survived and deceased patients were under 62 or palpable only on the common carotid artery, and there was no difference between survived and deceased patients. The mean pulse rate of the deceased patients was 76.5 while survived 117.7. Two deceased patients presented unconsciousness or conscious disorder while survived patients showed clear consciousness. The 2 deceased patients fell into VT just after arrival or during the operation. CONCLUSIONS In managing colonic obstruction, we should be aware of this potentially lethal disease and surgical treatment should be performed as soon as possible before the patients fall into LOC. Early diagnosis and early aggressive surgery is essential for managing LOC.
