Abstract
INTRODUCTION Malignant bowel obstruction (MBO) is a common complication of patients with advanced malignancies and has poor prognosis. Currently, there are limited guidelines for MBO management or predicting outcomes for these patients. OBJECTIVE To identify patient factors associated with readmission and mortality after hospital admission for MBO. PARTICIPANTS A 5-year retrospective review was performed from 2017 to 2022 at a single tertiary institution to evaluate patients admitted for MBO. All patients had advanced cancer of gastrointestinal or gynecologic primary. Patient demographics, socioeconomic factors, tumor characteristics, and inpatient outcomes were collected. Multivariable analyses were performed to determine variables predicting hospital readmission for recurrent MBO and 90-day mortality. RESULTS 210 patients were included. Mean age was 61 years, 28% were male, and 19% did not primarily speak English. 35% of patients lived over 50 miles from the hospital. On multivariable analysis, non-English speaking patients exhibited increased risk of readmission for MBO (OR = 2.82, P = .039). Older age was associated with decreased risk for MBO readmission (OR = .96, P = .007). Ascites was associated with increased mortality (OR = 2.17, P = .043). Earlier palliative care (PC) consultation predicted decreased readmission (OR = .24, P < .001) yet increased mortality at 90 days (OR = 3.20, P = .003). CONCLUSION Patient age, primary language, and PC consult were predictors for MBO readmission, which may impact 90-day mortality. Given the palliative nature of MBO, modifiable factors such as PC consultation and multidisciplinary goals of care discussions should be prioritized in order to reduce readmissions and focus on quality of life (QOL) for this patient population.

Abstract
BACKGROUND Small bowel obstruction (SBO) frequently necessitates emergency surgical intervention. The impact of frailty and age on operative outcomes is uncertain. This study evaluated postoperative outcomes of SBO surgery based on patient's age and frailty and explore the optimal timing to operation in elderly and/or frail patients. METHODS Patients who underwent SBO surgery were identified in American College of Surgeons National Surgical Quality Improvement Program database 2005 to 2021. Patients aged ≥65 years were defined as elderly. Patients with 5-Factor Modified Frailty Index≥2 were defined as frail. Multivariable logistic regression was used to compare 30-day postoperative outcomes between elderly frail versus nonfrail patients, as well as between nonfrail young versus elderly patients. RESULTS There were 49,344 patients who had SBO surgery, with 7,089 (14.37%) patients classified as elderly frail, 17,821 (36.12%) as elderly nonfrail, and 21,849 (44.28%) as young nonfrail. Elderly frail patients had higher mortality (adjusted odds ratio, 1.541; p < 0.01) and postoperative complications compared with their elderly nonfrail counterparts; these patients also had longer wait until definitive operation ( p < 0.01). Among nonfrail patients, when compared with young patients, the elderly had higher mortality (adjusted odds ratio, 2.388; p < 0.01) and complications, and longer time to operation ( p < 0.01). In elderly nonfrail patients, a higher mortality was observed when surgery was postponed after 2 days. Mortality risk for frail elderly patients is heightened from their already higher baseline when surgery is delayed after 4 days. CONCLUSION When SBO surgery is postponed for more than 2 days, elderly nonfrail patients have an increased mortality risk. Consequently, upon admission, these patients should be placed under a nasogastric tube and undergo an initial gastrograffin challenge. If there is no contrast in colon, they should be operated on within 2 days. Conversely, elderly frail patients with SBO have a higher mortality risk when surgery is delayed beyond 4 days. Thus, following the same scheme, they should be operated on before 4 days if gastrograffin challenge fails. LEVEL OF EVIDENCE Therapeutic/Care Management; Level III.

Abstract
BACKGROUND Intestinal obstruction represents a severe intestinal disease associated with higher mortality rates. However, the determinants of mortality in patients with intestinal obstruction remain inadequately understood. This study sought to elucidate the potential risk factors associated with mortality in the context of intestinal obstruction during the COVID-19 pandemic. METHODS A retrospective analysis was performed on a cohort of 227 patients diagnosed with intestinal obstruction at the First Hospital of Hebei Medical University, spanning the period from September 7, 2022, to January 7, 2023. The primary endpoint of the study was mortality within four weeks following discharge. Univariate and multivariable logistic regression models were utilized to evaluate the risk factors associated with mortality outcomes. RESULTS A cohort of 227 patients diagnosed with intestinal obstruction (median age, 59.02 years [IQR, 48.95-70.85 years]) was included in our study. Malignant bowel obstruction (MBO) and COVID-19 were identified as independent risk factors for mortality among these patients. Notably, the mortality rate increased significantly to 38.46% when MBO was concomitant with COVID-19. Furthermore, postoperative pulmonary complications (PPC) (OR, 54.21 [death]; 95% CI, 3.17-926.31), gastric cancer (OR, 9.71 [death]; 95% CI, 1.38-68.18), VTE (Caprini Score ≥ 5) (OR, 7.64 [death]; 95% CI, 1.37-42.51), and COVID-19 (OR, 5.72 [death]; 95% CI, 1.01-32.29) were all determined to be independent risk factors for postoperative mortality. Additionally, gastric cancer could have emerged as one of the most severe risk factors for mortality in individuals with intestinal obstruction within the cohort of cancer patients, of which gastric cancer exhibited higher mortality rates compared to individuals with other forms of cancer. CONCLUSION The study identifies MBO, gastric cancer, COVID-19, PPC, and VTE as potential risk factors for mortality in cases of intestinal obstruction. These findings highlight the necessity for continuous monitoring of indicators related to these mortality risk factors and their associated complications, thereby offering valuable insights for the management and treatment of intestinal obstruction.

Abstract
INTRODUCTION AND PURPOSE OF THE STUDY Small bowel obstruction (SBO) accounts for a substantial proportion of emergency surgical admissions. Malignancy is a common cause of obstruction, either due to a primary tumour or intra-abdominal metastases. However, little is known regarding the current treatment or outcomes of patients with malignant SBO. This study aimed to characterise the treatment of malignant SBO and identify areas for potential improvement and compare overall survival of patients with malignant SBO to patients with non-malignant SBO. MATERIALS AND METHODS This was a subgroup analysis of a multicentre observational study of patients admitted with SBO. Details regarding these patients' diagnoses, treatments, and outcomes up to 1-year after admission were recorded. The primary outcome was overall survival in patients with malignant SBO. RESULTS A total of 316 patients with small bowel obstruction were included, of whom 33 (10.4%) had malignant SBO. Out of the 33 patients with malignant SBO, 20 patients (60.6%) were treated with palliative intent although only 7 patients were seen by a palliative team during admission. Nutritional assessments were performed on 12 patients, and 11 of these patients received parenteral nutrition. 23 patients underwent surgery, with the most common surgical interventions being loop ileostomies (9 patients) and gastrointestinal bypasses (9 patients). 4 patients underwent right hemicolectomies, with a primary anastomosis formed and 1 patient had a right hemicolectomy with a terminal ileostomy. Median survival was 114 days, and no difference was seen in survival between patients treated with or without palliative intent. CONCLUSION Malignant SBO is associated with significant risks of short-term complications and a poor prognosis. Consideration should be given to the early involvement of senior decision-makers upon patient admission is essential for optimal management and setting expectation for a realistic outcome.

Abstract
BACKGROUND Bowel obstruction is a mechanical or functional blockade of intestinal contents from evacuation to the adjacent distal bowel or external environment. It poses significant morbidity and mortality in both high-income and low-to-middle-income countries. Ileosigmoid knotting is a special form of obstruction where the small bowel often ileum wraps around the sigmoid colon or vice versa. It is the severest form of bowel obstruction, involving both the small and large bowels in a compound manner. It is common where sigmoid volvulus is common and geographic areas with a bulky diet. METHODS An institution-based retrospective cohort study was employed among purposively selected 40 surgical patients with ileosigmoid knotting records from July 2020 to July 2023 at Jimma University Medical Center. To estimate and compare the survival probabilities, the Kaplan-Meir method and log-rank test were used. A Cox-regression analysis was fitted to identify independent predictors of time to death. RESULTS Among a cohort of 40 patients followed for 347 person-days at Jimma University Medical Center, 11 (27.5%) had died. The overall incidence rate of death was 3.2 (95% CI 1.8, 5.7) per 100 person-days. In multivariable Cox-regression analysis, age (AHR = 1.15; 95% CI: 1.04-1.28), shock at presentation (AHR = 30.50: 95% CI 1.25-742.54), comorbidities (AHR = 5.81; 95% CI 1.19-28.23), pulse rate intraoperatively (AHR = 1.19; 95% CI: 1.01-1.40), postoperative pulse rate (AHR = 1.07; 95% CI: 1.01-1.14) were independently associated with time to death. CONCLUSION The incidence of death among surgical patients with ileosigmoid knotting was high and also had a shorter median survival time. Age, shock at presentation, comorbidities, pulse rate intraoperatively, and postoperative pulse rate were found to be statistically significant predictors of time to death and outcome among surgical patients with Ileosigmoid knotting.

Abstract
BACKGROUND For relief of bowel obstruction in left-sided obstructive colon cancer (LSOCC), a self-expandable metal stent (SEMS) or decompressing stoma (DS) can be placed. In a curative setting, these two strategies have been extensively studied as a bridge to elective resection. Guidelines recommend SEMS as the preferred option in the palliative setting, but adherence in daily practice is unknown. Therefore, this study aimed to gain more insight into patients with LSOCC who received palliative treatment with SEMS or DS at a national level. METHODS A retrospective population-based cohort study was conducted in the Netherlands. Data from the Netherlands Cancer Registry (NCR) on all patients with LSOCC treated with DS or SEMS not followed by resection of the primary tumour between January 1, 2015, and December 31, 2019, were analysed. Type of treatment (DS or SEMS) for different clinical scenarios, was the main outcome of this study, and was also evaluated over the years (2015-2019). RESULTS Palliative treatment with SEMS or DS for LSOCC was performed in 1077 patients, of whom 79.2% had metastatic disease (M1). Patients without metastatic disease (M0) were older (≥ 80 years M0 67.4%, M1 25.3%, P < 0.001), had a worse clinical condition (ASA III 51.4% versus 36.37%, ASA IV-V 13.3% versus 4.0% P < 0.001) and presented with higher tumour stage (cT4 55.4% versus 33.5%, % P < 0.001). DS was performed in 91.5% of the patients and SEMS in 8.5%. The proportion of DS did not significantly differ between patients with M1 and M0 (91.8% vs. 90.2% respectively, P = 0.525). No increase in SEMS application was observed over the years, with a stable overall proportion of DS of 91-92% per year. In the multivariable analyses, ninety-day mortality and overall survival were not significantly different between SEMS and DS. CONCLUSIONS This study revealed that DS was the primary treatment modality for palliative management of LSOCC in the Netherlands between 2015 and 2019, while the guidelines recommended SEMS as preferred treatment. For patients with LSOCC eligible for stenting in the palliative setting, SEMS placement should become more available and accessible as the preferred treatment option, to avoid a stoma in the terminal phase of life.

Abstract
Palliative care patients with malignant bowel obstruction are particularly at risk of developing malnutrition, which in turn directly shortens survival time and worsens quality of life (QoL). According to the available data, the survival time in this patient group is often less than three months. To avoid further complications related to malnutrition and poor outcomes in oncological therapy, nutritional therapy such as home parenteral nutrition (HPN) is offered. The aim of this study was to investigate whether nutritional status is a prognostic factor for survival in palliative care patients with malignant inoperable bowel obstruction qualified for home parenteral nutrition and which nutritional assessment tool has the most accurate prognostic value. This retrospective observational analysis included 200 patients with malignant bowel obstruction referred for home parenteral nutrition between January 2018 and August 2023. The analysis included laboratory test results, body mass index (BMI), Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Geriatric Nutritional Risk Index (GNRI), Prognostic Nutritional Index (PNI) and malnutrition as defined by the Global Leadership Initiative on Malnutrition (GLIM). The average survival time of the patients was 75 days. Patients with higher NRI and PNI scores were more likely to survive (NRI: p < 0.001; PNI: p < 0.001). The GLIM criteria, SGA scores and BMI values did not prove to be good prognostic factors for survival (GLIM p = 0.922, SGA p = 0.083, BMI p = 0.092). The results suggest that the use of NRI and PNI may be helpful in prognosing survival in these patients and that prevention of the development of malnutrition through earlier nutritional assessment and intervention should be considered in this patient group.

Abstract
BACKGROUND Emergency general surgery conditions are common, costly, and highly morbid. The proportion of excess morbidity due to variation in health systems and processes of care is poorly understood. We constructed a collaborative quality initiative for emergency general surgery to investigate the emergency general surgery care provided and guide process improvements. METHODS We collected data at 10 hospitals from July 2019 to December 2022. Five cohorts were defined: acute appendicitis, acute gallbladder disease, small bowel obstruction, emergency laparotomy, and overall aggregate. Processes and inpatient outcomes investigated included operative versus nonoperative management, mortality, morbidity (mortality and/or complication), readmissions, and length of stay. Multivariable risk adjustment accounted for variations in demographic, comorbid, anatomic, and disease traits. RESULTS Of the 19,956 emergency general surgery patients, 56.8% were female and 82.8% were White, and the mean (SD) age was 53.3 (20.8) years. After accounting for patient and disease factors, the adjusted aggregate mortality rate was 3.5% (95% confidence interval [CI], 3.2-3.7), morbidity rate was 27.6% (95% CI, 27.0-28.3), and the readmission rate was 15.1% (95% CI, 14.6-15.6). Operative management varied between hospitals from 70.9% to 96.9% for acute appendicitis and 19.8% to 79.4% for small bowel obstruction. Significant differences in outcomes between hospitals were observed with high- and low-outlier performers identified after risk adjustment in the overall cohort for mortality, morbidity, and readmissions. The use of a Gastrografin challenge in patients with a small bowel obstruction ranged from 10.7% to 61.4% of patients. In patients who underwent initial nonoperative management of acute cholecystitis, 51.5% had a cholecystostomy tube placed. The cholecystostomy tube placement rate ranged from 23.5% to 62.1% across hospitals. CONCLUSION A multihospital emergency general surgery collaborative reveals high morbidity with substantial variability in processes and outcomes among hospitals. A targeted collaborative quality improvement effort can identify outliers in emergency general surgery care and may provide a mechanism to optimize outcomes.

Abstract
BACKGROUND KRAS and BRAF testing is currently recommended in metastatic colorectal cancer. There is evidence that KRAS and BRAF mutation status may act as a prognostic biomarker in patients with non-metastatic colorectal cancer. Data is limited on whether KRAS and BRAF mutation status impacts recurrence and mortality in patients with non-metastatic colorectal cancer. METHODS A retrospective cohort study was conducted in a tertiary hospital examining outcomes in patients who had KRAS and BRAF testing for colorectal cancer in 2017. Primary outcomes were all-cause mortality and recurrence. Multivariable analysis for both outcomes, used cause specific Cox proportional hazards models with KRAS/BRAF status as exposure. For time to recurrence, a sensitivity analysis was performed with a weighted Fine-Grey model with death as a competing risk. RESULTS KRAS mutation status was not associated with all-cause mortality (average Hazard Ratio (aHR) = 0.78, 95% CI 0.28-2.21) or recurrence (aHR = 0.96, 95% CI 0.32-2.86). BRAF mutation status was not associated with time to all-cause mortality (aHR = 3.06, 95% CI 0.79-11.8) or recurrence (aHR = 0.94, 95% CI 0.13-6.57). Increased risk of recurrence was significantly associated with large bowel obstruction (aHR = 2.73, 95% CI 1.16-6.45) and anaemia (aHR = 3.39, 95% CI 1.06-10.8) at time of surgery. CONCLUSION This study did not demonstrate an association between KRAS and BRAF mutations and all-cause mortality or recurrence. A significantly increased risk of cancer recurrence was found in patients with large bowel obstruction and in patients with anaemia at time of surgery. Anaemia should be promptly investigated and corrected prior to colorectal cancer surgery.

Abstract
BACKGROUND Small bowel obstructions (SBO) are one of the most common surgical emergencies, but they remain a major cause of high morbidity and mortality in patients with previous history of abdominal and pelvic surgery. Socioeconomic factors have not been extensively studied in surgical management of SBO. METHODS We queried the 2016 NRD database for all surgically managed admissions ≥18 years of age with a primary diagnosis of SBO. The primary outcomes for this analysis were index admission mortality, 30-day mortality, and 30-day readmissions. Multivariate logistic regression models were utilized to examine the association between predictors and primary outcomes. RESULTS Medicaid patients had a higher likelihood of index admission mortality. Medicare and Medicaid patients both had higher likelihoods of 30-day readmissions.results CONCLUSIONS: Careful consideration should be taken before deciding the optimal surgical approach in patients with SBO. Medicaid beneficiaries and those with existing comorbidities should receive careful post-operative follow-up to ensure optimal outcomes. CONCLUSION

Abstract
PURPOSE This study investigated the short- and long-term outcomes of 18- and 22-mm-diameter self-expandable metallic stent (SEMS) as a bridge to surgery (BTS) in patients with malignant large bowel obstruction (MLBO). METHODS Sixty-nine pathological stage II and III colorectal cancer patients who underwent BTS were included in this multi-institutional retrospective study. Patients were divided into two groups regarding the diameter of SEMS: an 18-mm group (n = 30) and a 22-mm group (n = 39). RESULTS There was no significant difference in the clinical success rate, but both of the two re-obstructions observed occurred in the 18-mm group. The 18-mm group showed a trend toward a higher incidence of overall postoperative complications (Clavien-Dindo grading ≥ II) than the 22-mm group (33.3% vs. 10.3%, P = 0.061). The 3-year disease-free and overall survival showed no significant differences between the 18- and 22-mm groups (78.2% vs. 68.8%, P = 0.753 and 92.8% vs. 82.1%, P = 0.471, respectively). CONCLUSION SEMS of 18 and 22 mm diameter confer statistically equivalent short- and long-term outcomes as a BTS.

Abstract
Background Abdominal wall hernia is a common surgical condition. Patients may present in an emergency with bowel obstruction, incarceration or strangulation. Small bowel obstruction (SBO) is a serious surgical condition associated with significant morbidity. The aim of this study was to describe current management and outcomes of patients with obstructed hernia in the UK as identified in the National Audit of Small Bowel Obstruction (NASBO). Methods NASBO collated data on adults treated for SBO at 131 UK hospitals between January and March 2017. Those with obstruction due to abdominal wall hernia were included in this study. Demographics, co‐morbidity, imaging, operative treatment, and in‐hospital outcomes were recorded. Modelling for factors associated with mortality and complications was undertaken using Cox proportional hazards and multivariable regression modelling. Results NASBO included 2341 patients, of whom 415 (17·7 per cent) had SBO due to hernia. Surgery was performed in 312 (75·2 per cent) of the 415 patients; small bowel resection was required in 198 (63·5 per cent) of these operations. Non‐operative management was reported in 35 (54 per cent) of 65 patients with a parastomal hernia and in 34 (32·1 per cent) of 106 patients with an incisional hernia. The in‐hospital mortality rate was 9·4 per cent (39 of 415), and was highest in patients with a groin hernia (11·1 per cent, 17 of 153). Complications were common, including lower respiratory tract infection in 16·3 per cent of patients with a groin hernia. Increased age was associated with an increased risk of death (hazard ratio 1·05, 95 per cent c.i. 1·01 to 1·10; P = 0·009) and complications (odds ratio 1·05, 95 per cent c.i. 1·02 to 1·09; P = 0·001). Conclusion NASBO has highlighted poor outcomes for patients with SBO due to hernia, highlighting the need for quality improvement initiatives in this group.

Abstract
BACKGROUND Ileo-sigmoid knotting is a rare cause of intestinal obstruction with a rapidly progressive course, for which expedient surgical intervention is required to prevent mortality. The aim of this study was to determine the characteristics, presentation, morbidity and mortality associated with ileo-sigmoid knotting at Parirenyatwa Group of Hospitals (PGH). To determine the preoperative diagnostic precision and management patterns of ileo-sigmoid knotting cases at PGH. METHODS A retrospective analysis was performed on patients operated on at Parirenyatwa Hospital with a diagnosis of ileo-sigmoid knotting between April 2011 and April 2018. Data inclusive of demographics, time to presentation and surgery, preoperative diagnosis, complications and in-hospital mortality was collected. The relationship between the duration of symptoms prior to surgery and incidence of both septic shock and transfusion were analysed. RESULTS Twenty-one cases of ileo-sigmoid knotting were identified for analysis. The median age was 37 years (range 18-65 years) with a 6:1 male to female ratio. Two of the three females included were pregnant. Twenty patients (95.2%) described an acute onset abdominal pain, with 83.3% experiencing the pain nocturnally, while asleep. The median duration of symptoms at presentation was 12.5 hours (range 2-39 hours). At admission, leucocytosis (WCC > 11x10³/dl) was noted in eleven patients (52.4%). Seventy-three per cent of patients were noted to have electrolyte derangements at presentation. Seven patients (33.3%) had recorded episodes of severe hypotension (SBP < 90) prior to surgery. The most common preoperative diagnosis, based on both clinical assessment and plain x-ray evaluation, was sigmoid volvulus (52.4%), with no preoperative diagnosis of ileo-sigmoid knotting being made. All patients had gangrenous small bowel, with 81% having a gangrenous sigmoid colon. All cases underwent small bowel resection and primary anastomosis plus Hartmann's procedure. Postoperatively, eleven patients (52.4%) developed septic shock, while 62% required blood transfusion. There was one (4.8%) early postoperative mortality. CONCLUSION To avoid mortality, the diagnosis of ileo-sigmoid knotting should be entertained and the imperative of emergency surgery recognised in the young male or pregnant female patient with acute nocturnal onset abdominal pain, a rapidly deteriorating small bowel obstruction clinical picture and with radiological features suggestive of both small and large bowel obstruction.

[PMID: 31543687 PMCID: PMC6737316 DOI: 10.3748/wjg.v25.i33.4970] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2019] [Revised: 06/09/2019] [Accepted: 07/19/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Obstructive colorectal cancer (OCC) is always accompanied by severe complications, and the optimal strategy for patients with OCC remains undetermined. Different from emergency surgery (ES), self-expandable metal stents (SEMS) as a bridge to surgery (BTS), could increase the likelihood of primary anastomosis. However, the stent failure and related complications might give rise to a high recurrence rate. Few studies have focused on the indications for either method, and the relationship between preoperative inflammation indexes and the prognosis of OCC is still underestimated.
AIM To explore the indications for ES and BTS in OCCs based on preoperative inflammation indexes.
METHODS One hundred and twenty-eight patients who underwent ES or BTS from 2008 to 2015 were enrolled. Receiver operating characteristic (ROC) curve analysis was used to define the optimal preoperative inflammation index and its cutoff point. Kaplan–Meier analyses and Cox proportional hazards models were applied to assess the association between the preoperative inflammation indexes and the survival outcomes [overall survival (OS) and disease-free survival (DFS)]. Stratification analysis was performed to identify the subgroups that would benefit from ES or BTS.
RESULTS OS and DFS were comparable between the ES and BTS groups (P > 0.05). ROC curve analysis showed derived neutrophil-to-lymphocyte ratio (dNLR) as the optimal biomarker for the prediction of DFS in ES (P < 0.05). Lymphocyte-to-monocyte ratio (LMR) was recommended for BTS with regard to OS and DFS (P < 0.05). dNLR was related to stoma construction (P = 0.001), pneumonia (P = 0.054), and DFS (P = 0.009) in ES. LMR was closely related to lymph node invasion (LVI) (P = 0.009), OS (P = 0.020), and DFS (P = 0.046) in the BTS group. dNLR was an independent risk factor for ES in both OS (P = 0.032) and DFS (P = 0.016). LMR affected OS (P = 0.053) and DFS (P = 0.052) in the BTS group. LMR could differentiate the OS between the ES and BTS groups (P < 0.05).
CONCLUSION Preoperative dNLR and LMR could predict OS and DFS in patients undergoing ES and BTS, respectively. For OCC, as the potential benefit group, patients with a low LMR might be preferred for BTS via SEMS insertion.

Abstract
Background: Malignant intestinal obstruction is a frequent complication in advanced stages cancer patients. The prognosis is poor, with mean survival rate beneath 3 months. Clinical treatment, endoscopic or surgical procedures are options for malignant intestinal obstruction management. There is no generally accepted management strategy. Objectives: To evaluate prognostic factors of patients with malignant intestinal obstruction who underwent surgical treatment. Methods: A retrospective analysis was performed including patients of a single institution with diagnosis of malignant intestinal obstruction. Demographic data, in-hospital stay, postoperative complications, and overall survival were assessed. Logistic regression was used to evaluate associated prognostic factors. Results: Two hundred thirty-three surgeries were performed due to suspicion for malignant intestinal obstruction over a seven-year period. This diagnosis was confirmed in 210 operations (90.1%). The main causes of malignant obstruction were colorectal (49.5%) and gynecological cancer (21.9%). The rate of severe complications was 11.42%. In-hospital mortality rate was 40.95% (CI 95%: 34.16-47.74%). Functional status impairment,high serum urea, and low albumin levels were associated to higher mortality rate. Conclusion: Malignant intestinal obstruction implies poor prognosis, with high in-hospital mortality rate and severe postoperative complications. The decision regarding management of malignant intestinal obstruction must be multimodal and individualized, according to individual prognostic factors.

Abstract
BACKGROUND Emergency surgical resection is a standard treatment for right-sided malignant colonic obstruction; however, the procedure is associated with high rates of mortality and morbidity. Although a bridge to surgery can be created to obviate the need for emergency surgery, its effects on long-term outcomes and the most practical management strategies for right-sided malignant colonic obstruction remain unclear.
AIM To determine the appropriate management approach for right-sided malignant colonic obstruction.
METHODS Forty patients with right-sided malignant colonic obstruction who underwent curative resection from January 2007 to April 2017 were included in the study. We compared the perioperative and long-term outcomes of patients who received bridges to surgery established using decompression tubes and those created using self-expandable metallic stents (SEMS). The primary outcome was the overall survival duration (OS) and the secondary endpoints were the disease-free survival (DFS) duration and the preoperative and postoperative morbidity rates. Analysis was performed on an intention-to-treat basis.
RESULTS There were 21 patients in the decompression tube group and 19 in the SEMS group. There were no significant differences in the perioperative morbidity rates of the two groups. The OS rate was significantly higher in the decompression tube group than in the SEMS group (5-year OS rate; decompression tube 79.5%, SEMS 32%, P = 0.043). Multivariate analysis revealed that the bridge to surgery using a decompression tube was significantly associated with the OS (hazard ratio, 17.41; P = 0.004). The 3-year DFS rate was significantly higher in the decompression tube group than in the SEMS group (68.9% vs 45.9%; log-rank test, P = 0.032). A propensity score–adjusted analysis also demonstrated that the prognosis was significantly better in the decompression tube group than in the SEMS group.
CONCLUSION The bridge to surgery using trans-nasal and trans-anal decompression tubes for right-sided malignant colonic obstruction is safe and may improve long-term outcomes.

Abstract
BACKGROUND Although adhesive small-bowel obstruction (ASBO) is frequently managed nonoperatively, little is known regarding outcomes on readmission following this approach. Using a large population-based dataset, we evaluated risk factors for operative intervention and mortality at readmission in patients with ASBO who were initially managed nonoperatively. METHODS The ASBO patients were identified in the California Office of Statewide Health Planning and Development 2007 to 2014 patient discharge database. Patients who were managed operatively at index admission or had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for nonadhesive obstructive small bowel disease were excluded. Associations between risk factors and both operative intervention and death following readmission were evaluated using survival analysis. RESULTS Among 15,963 ASBO patients, 3,103 (19.4%) had at least one readmission. The 1,069 (34.5%) who received an operation during their first readmission presented sooner (175 days vs. 316 days, p < 0.001) and were more likely to die during that readmission (5.2% vs. 0.7%, p < 0.001). Operative management at first readmission was associated with younger age, fewer comorbidities, and shorter times to readmission. Patients operatively managed at first readmission had longer times to second readmission compared with nonoperative patients. Stratified analyses using nonoperative patients as the reference over the study period revealed that patients who underwent lysis of adhesions and bowel resection were 5.04 times (95% confidence interval [CI], 2.82-9.00) as likely to die while those who underwent lysis only were 2.09 times (95% CI, 1.14-3.85) as likely to die. Patients with bowel resection only were at an increased risk for subsequent interventions beyond the first readmission (hazard ratio, 1.79; 95% CI, 1.11-2.87). CONCLUSION In a large cohort readmitted for ASBO and initially managed nonoperatively, subsequent operative intervention conferred a greater risk of death and a longer time to readmission among survivors. Prospective research is needed to further delineate outcomes associated with initial nonoperative management of ASBO. LEVEL OF EVIDENCE Prognostic and epidemiological, level III.

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
Modern surgical and intensive care achievements did not result decrease of mortality in patients with acute small bowel obstruction (ASBO). Direct cause of mortality in ASBO patients is peritonitis followed by multiple organ failure syndrome including acute failure of liver, kidneys, lungs and other organs. Publications devoted to the problem of acute liver failure and its complicationsare reviewed in the article. Mechanisms of pathogenesis and clinical manifestations of multiple organ failure syndrome in patients with acute small bowel obstruction are analyzed.

Abstract
BACKGROUND The American Association for the Surgery of Trauma (AAST) anatomic severity grading system for adhesive small bowel obstruction (ASBO) has demonstrated to be a valid tool in North American patient populations. Using a multi-national patient cohort, we retrospectively assessed the validity the AAST ASBO grading system and estimated disease severity in a global population in order to correlate with several key clinical outcomes. METHODS Multicenter retrospective review during 2012-2016 from four centers, Minnesota USA, Bologna Italy, Pietermaritzburg South Africa, and Bucharest Romania, was performed. Adult patients (age ≥ 18) with ASBO were identified. Baseline demographics, physiologic parameters, laboratory results, operative and imaging details, outcomes were collected. AAST ASBO grades were assigned by independent reviewers. Univariate and multivariable analyses with odds ratio (OR) and 95% confidence intervals (CIs) were performed. RESULTS There were 789 patients with a median [IQR] age of 58 [40-75] years; 47% were female. The AAST ASBO grades were I (n = 180, 23%), II (n = 443, 56%), III (n = 87, 11%), and IV (n = 79, 10%). Successful non-operative management was 58%. Conversion rate from laparoscopy to laparotomy was 33%. Overall mortality and complication and temporary abdominal closure rates were 2, 46, and 4.7%, respectively. On regression, independent predictors for mortality included grade III (OR 4.4 95%CI 1.1-7.3), grade IV (OR 7.4 95%CI 1.7-9.4), pneumonia (OR 5.6 95%CI 1.4-11.3), and failing non-operative management (OR 2.4 95%CI 1.3-6.7). CONCLUSION The AAST EGS grade can be assigned with ease at any surgical facility using operative or imaging findings. The AAST ASBO severity grading system has predictive validity for important clinical outcomes and allows for standardization across institutions, providers, and future research. Disease severity and outcomes varied between countries. LEVEL OF EVIDENCE III Study type Retrospective multi-institutional cohort study.

Abstract
BACKGROUND People with advanced ovarian or gastrointestinal cancer may develop malignant bowel obstruction (MBO). They are able to tolerate limited, if any, oral or enteral (via a tube directly into the gut) nutrition. Parenteral nutrition (PN) is the provision of macronutrients, micronutrients, electrolytes and fluid infused as an intravenous solution and provides a method for these people to receive nutrients. There are clinical and ethical arguments for and against the administration of PN to people receiving palliative care. OBJECTIVES To assess the effectiveness of home parenteral nutrition (HPN) in improving survival and quality of life in people with inoperable MBO. SEARCH METHODS We searched the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1), MEDLINE (Ovid), Embase (Ovid), BNI, CINAHL, Web of Science and NHS Economic Evaluation and Health Technology Assessment up to January 2018, ClinicalTrials.gov (http://clinicaltrials.gov/) and in the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal (http://apps.who.int/trialsearch/). In addition, we handsearched included studies and used the 'Similar articles' feature on PubMed for included articles. SELECTION CRITERIA We included any studies with more than five participants investigating HPN in people over 16 years of age with inoperable MBO. DATA COLLECTION AND ANALYSIS We extracted the data and assessed risk of bias for each study. We entered data into Review Manager 5 and used GRADEpro to assess the quality of the evidence. MAIN RESULTS We included 13 studies with a total of 721 participants in the review. The studies were observational, 12 studies had only one relevant treatment arm and no control and for the one study with a control arm, very few details were given. The risk of bias was high and the certainty of evidence was graded as very low for all outcomes. Due to heterogeneity of data, meta-analysis was not performed and therefore the data were synthesised via a narrative summary.The evidence for benefit derived from PN was very low for survival and quality of life. All the studies measured overall survival and 636 (88%) of participants were deceased at the end of the study. However there were varying definitions of overall survival that yielded median survival intervals between 15 to 155 days (range three to 1278 days). Three studies used validated measures of quality of life. The results from assessment of quality of life were equivocal; one study reported improvements up until three months and two studies reported approximately similar numbers of participants with improvements and deterioration. Different quality of life scales were used in each of the studies and quality of life was measured at different time points. Due to the very low certainty of the evidence, we are very uncertain about the adverse events related to PN use. Adverse events were measured by nine studies and data for individual participants could be extracted from eight studies. This revealed that 32 of 260 (12%) patients developed a central venous catheter infection or were hospitalised because of complications related to PN. AUTHORS' CONCLUSIONS We are very uncertain whether HPN improves survival or quality of life in people with MBO as the certainty of evidence was very low for both outcomes. As the evidence base is limited and at high risk of bias, further higher-quality prospective studies are required.

Abstract
Encapsulating peritoneal sclerosis (EPS) is a debilitating condition characterized by a fibrocollagenous membrane encasing the small intestine, resulting in recurrent small bowel obstructions. EPS is most commonly associated with long-term peritoneal dialysis, though medications, peritoneal infection, and systemic inflammatory disorders have been implicated. Many cases remain idiopathic. Diagnosis is often delayed given the rarity of the disorder combined with non-specific symptoms and laboratory findings. Although cross-sectional imaging with computed tomography of the abdomen can be suggestive of the disorder, many patients undergo exploratory laparotomy for diagnosis. Mortality approaches 50% one year after diagnosis. Treatment for EPS involves treating the underlying condition or eliminating possible inciting agents (i.e. peritoneal dialysis, medications, infections) and nutritional support, frequently with total parenteral nutrition. EPS-specific treatment depends on the disease stage. In the inflammatory stage, corticosteroids are the treatment of choice, while in the fibrotic stage, tamoxifen may be beneficial. In practice, distinguishing between stages may be difficult and both may be used. Surgical intervention, consisting of peritonectomy and enterolysis, is time-consuming and high-risk and is reserved for situations in which conservative medical therapy fails in institutions with surgical expertise in this area. Herein we review the available literature of the etiology, pathogenesis, diagnosis, and treatment of this rare, but potentially devastating disease.

Abstract
Background Self-expandable metallic stenting (SEMS) for malignant colorectal obstruction (MCO) as a bridge to elective surgery (BTS) is a widely used procedure. The aim of this study was to assess short-term outcomes of SEMS for MCO as BTS. Methods This study analyzed pooled data from BTS patients who were enrolled in two multicenter prospective single-arm observational clinical studies that used different stent types. Both studies were conducted by the Japan Colonic Stent Safe Procedure Research Group (JCSSPRG). The first study evaluated the WallFlex™ colonic stent for BTS or palliative treatment (PAL) from May 2012 to October 2013 and the second evaluated the Niti-S™ colonic stent from October 2013 to May 2014. Fifty-three facilities in Japan participated in the studies. Before each study started, the procedure had been shared with the participating institutions by posting details of the standard methods of SEMS placement on the JCSSPRG website. Patients were followed until discharged after surgery. Results A total of 723 consecutive patients were enrolled in the two studies. After excluding nine patients, the remaining 714 patients were evaluated as a per-protocol cohort. SEMS placement was performed in 426 patients (312 WallFlex and 114 Niti-S) as BTS and in 288 as PAL. In the 426 BTS patients, the technical success rate was 98.1% (418/426). The clinical success rate was 93.8% (392/418). SEMS-related preoperative complications occurred in 8.5% of patients (36/426), perforations in 1.9% (8/426), and stent migration in 1.2% (5/426). Primary anastomosis was possible in 91.8% of patients (391/426), 3.8% of whom (15/393) had anastomosis leakage. The overall stoma creation rate was 10.6% (45/426). The postoperative complication rate was 16.9% (72/426) and mortality rate was 0.5% (2/426). Conclusions SEMS placement for MCO as BTS is safe and effective with respect to peri-procedural outcomes. Further investigations are needed to confirm long-term oncological outcomes.

Abstract
Emergency general surgery (EGS) is defined as the urgent assessment and treatment of nontrauma, general surgical emergencies involving adults. Acute surgical emergencies often represent the most common reason for hospital admission with diagnoses, including bowel obstruction and appendicitis. EGS is a growing surgical subspecialty that includes both operative and nonoperative management of acutely ill patients. We sought to assess the burden of nonoperative care in EGS patients at our academic medical center. This study was conducted by retrospective analysis of prospectively collected data from patients entered into the Duke EGS Registry between July 1, 2016 and September 10, 2017. Fifty-six per cent (n = 771) of patients in the Duke EGS Registry (n = 1377) were managed nonoperatively as compared with 44 per cent (n = 606) who were managed operatively. Nonoperative management of disease represents a large subset of EGS and, therefore, needs further investigation to improve processes, outcomes, and standardization of care.

Abstract
OBJECTIVE To compare survival, readmissions, and end-of-life care after palliative procedures compared with medical management for malignancy-associated bowel obstruction (MBO). BACKGROUND MBO is a late complication of intra-abdominal malignancy for which surgeons are frequently consulted. Decisions about palliative treatments, which include medical management, surgery, or venting gastrostomy tube (VGT), are hampered by the paucity of outcomes data relevant to patients approaching the end of life. METHODS Retrospective study using 2001 to 2012 Surveillance, Epidemiology, and End Results-Medicare data of patients 65 years or older with stage IV ovarian or pancreatic cancer who were hospitalized for MBO. Multivariate competing-risks regression models were used to compare the following outcomes: survival, readmission for MBO, hospice enrollment, intensive care unit (ICU) care in the last days of life, and location of death in an acute care hospital. RESULTS Median survival after MBO admission was 76 days (interquartile range 26-319 days). Survival was shorter after VGT [38 days (interquartile range 23-69)] than medical management [72 days (23-312)] or surgery [128 days (42-483)]. As compared to medical management, patients treated with VGT had fewer readmissions [subdistribution hazard ratio 0.41 (0.29-0.58)], increased hospice enrollment [1.65 (1.42-1.91)], and less ICU care [0.69 (0.52-0.93)] and in-hospital death [0.47 (0.36-0.63)]. Surgery was associated with fewer readmissions [0.69 (0.59-0.80)], decreased hospice enrollment [0.84 (0.76-0.92)], and higher likelihood of ICU care [1.38 (1.17-1.64)]. CONCLUSIONS VGT is associated with fewer readmissions and lower intensity healthcare utilization at the end of life than do medical management or surgery. Given the limited survival, regardless of management, hospitalization with MBO carries prognostic significance and presents a critical opportunity to identify patients' priorities for end-of-life care.
