Small bowel obstruction in the elderly: a plea for comprehensive acute geriatric care. World J Emerg Surg 2018; 13:48. [PMID: 30377439 PMCID: PMC6196030 DOI: 10.1186/s13017-018-0208-z] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2018] [Accepted: 09/24/2018] [Indexed: 12/16/2022] Open
Abstract
Small bowel obstruction is one of the most frequent emergencies in general surgery, commonly affecting elderly patients. Morbidity and mortality from small bowel obstruction in elderly is high. Significant progress has been made in the diagnosis and management of bowel obstruction in recent years. But little is known whether this progress has benefitted outcomes in elderly patients, particularly those who are frail or have a malignancy as cause of the obstruction, and when considering quality of life and functioning as outcomes. In this review, we discuss the specific challenges and needs of elderly in diagnosis and treatment of small bowel obstruction. We address quality of life aspects and explore how the concept of geriatric assessment can be utilized to improve decision-making and outcomes for elderly patients with a small bowel obstruction.

Abstract
BACKGROUND This is an update of the original Cochrane review published in Issue 4, 2000. Intestinal obstruction commonly occurs in progressive advanced gynaecological and gastrointestinal cancers. Management of these patients is difficult due to the patients' deteriorating mobility and function (performance status), the lack of further chemotherapeutic options, and the high mortality and morbidity associated with palliative surgery. There are marked variations in clinical practice concerning surgery in these patients between different countries, gynaecological oncology units and general hospitals, as well as referral patterns from oncologists under whom these patients are often admitted. OBJECTIVES To assess the efficacy of surgery for intestinal obstruction due to advanced gynaecological and gastrointestinal cancer. SEARCH METHODS We searched the following databases for the original review in 2000 and again for this update in June 2015: CENTRAL (2015, Issue 6); MEDLINE (OVID June week 1 2015); and EMBASE (OVID week 24, 2015).We also searched relevant journals, bibliographic databases, conference proceedings, reference lists, grey literature and the world wide web for the original review in 2000; we also used personal contact. This searching of other resources yielded very few additional studies. The Cochrane Pain, Palliative and Supportive Care Review Group no longer routinely handsearch journals. For these reasons, we did not repeat the searching of other resources for the June 2015 update. SELECTION CRITERIA As the review concentrates on the 'best evidence' available for the role of surgery in malignant bowel obstruction in known advanced gynaecological and gastrointestinal cancer we kept the inclusion criteria broad (including both prospective and retrospective studies) so as to include all studies relevant to the question. We sought published trials reporting on the effects of surgery for resolving symptoms in malignant bowel obstruction for adult patients with known advanced gynaecological and gastrointestinal cancer. DATA COLLECTION AND ANALYSIS We used data extraction forms to collect data from the studies included in the review. Two review authors extracted the data independently to reduce error. Owing to concerns about the risk of bias we decided not to conduct a meta-analysis of data and we have presented a narrative description of the study results. We planned to resolve disagreements by discussion with the third review author. MAIN RESULTS In total we have identified 43 studies examining 4265 participants. The original review included 938 patients from 25 studies. The updated search identified an additional 18 studies with a combined total of 3327 participants between 1997 and June 2015. The results of these studies did not change the conclusions of the original review.No firm conclusions can be drawn from the many retrospective case series so the role of surgery in malignant bowel obstruction remains controversial. Clinical resolution varies from 26.7% to over 68%, though it is often unclear how this is defined. Despite being an inadequate proxy for symptom resolution or quality of life, the ability to feed orally was a popular outcome measure, with success rates ranging from 30% to 100%. Rates of re-obstruction varied, ranging from 0% to 63%, though time to re-obstruction was often not included. Postoperative morbidity and mortality also varied widely, although again the definition of both of these surgical outcomes differed between many of the papers. There were no data available for quality of life. The reporting of adverse effects was variable and this has been described where available. Where discussed, surgical procedures varied considerably and outcomes were not reported by specific intervention. Using the 'Risk of bias' assessment tool, most included studies were at high risk of bias for most domains. AUTHORS' CONCLUSIONS The role of surgery in malignant bowel obstruction needs careful evaluation, using validated outcome measures of symptom control and quality of life scores. Further information could include re-obstruction rates together with the morbidity associated with the various surgical procedures.Currently, bowel obstruction is managed empirically and there are marked variations in clinical practice by different units. In order to compare outcomes in malignant bowel obstruction, there needs to be a greater degree of standardisation of management.Since the last version of this review none of the new included studies have provided additional information to change the conclusions.

Abstract
An oncologic emergency is defined as an acute, potentially life threatening condition in a cancer patient that has developed as a result of the malignant disease or its treatment. Many oncologic emergencies are signs of advanced, end-stage malignant disease. Oncologic emergencies can be divided into medical or surgical. The literature was reviewed to construct a summary of potential surgical emergencies in oncology that any surgeon can be confronted with in daily practice, and to offer insight into the current approach for these wide ranged emergencies. Cancer patients can experience symptoms of obstruction of different structures and various causes. Obstruction of the gastrointestinal tract is the most frequent condition seen in surgical practice. Further surgical emergencies include infections due to immune deficiency, perforation of the gastrointestinal tract, bleeding events, and pathological fractures. For the institution of the appropriate treatment for any emergency, it is important to determine the underlying cause, since emergencies can be either benign or malignant of origin. Some emergencies are well managed with conservative or non-invasive treatment, whereas others require emergency surgery. The patient's performance status, cancer stage and prognosis, type and severity of the emergency, and the patient's wishes regarding invasiveness of treatment are essential during the decision making process for optimal management.

Abstract
IMPORTANCE Research has been limited on the incidence, mechanisms, etiology, and treatment of symptoms that require palliation in patients with terminal cancer. Bowel obstruction (BO) is a common complication of advanced abdominal cancer, including colon cancer, for which small, single-institution studies have suggested an incidence rate of 15% to 29%. Large population-based studies examining the incidence or risk factors associated with BO in cancer are lacking. OBJECTIVE To investigate the incidence and risk factors associated with BO in patients with stage IV colon cancer. DESIGN AND SETTING Retrospective cohort, population-based study of patients in the Surveillance, Epidemiology, and End Results and Medicare claims linked databases who were diagnosed as having stage IV colon cancer from January 1, 1991, through December 31, 2005. PATIENTS Patients 65 years or older with stage IV colon cancer (n = 12 553). MAIN OUTCOMES AND MEASURES Time to BO, defined by inpatient hospitalization for BO. We used Cox proportional hazards regression models to determine associations between BO and patient, prior treatment, and tumor features. RESULTS We identified 1004 patients with stage IV colon cancer subsequently hospitalized with BO (8.0%). In multivariable analysis, proximal tumor site (hazard ratio, 1.22 [95% CI, 1.07-1.40]), high tumor grade (1.34 [1.16-1.55]), mucinous histological type (1.27 [1.08-1.50]), and nodal stage N2 (1.52 [1.26-1.84]) were associated with increased risk of BO, as was the presence of obstruction at cancer diagnosis (1.75 [1.47-2.04]). A more recent diagnosis was associated with decreased risk of subsequent obstruction (hazard ratio, 0.84 [95% CI, 0.72-0.98]). CONCLUSIONS AND RELEVANCE In this large population of patients with stage IV colon cancer, BO after diagnosis was less common (8.0%) than previously reported. Risk was associated with site and histological type of the primary tumor. Future studies will explore management and outcomes in this serious, common complication.

Abstract
BACKGROUND Bowel obstruction is a common complication of late-stage abdominal cancer, especially colon cancer, which has been investigated predominantly in small, single-institution studies. OBJECTIVE We used a large, population-based data set to explore the surgical treatment of bowel obstruction and its outcomes after hospitalization for obstruction among patients with stage IV colon cancer. DESIGN This was a retrospective cohort study. SETTING AND PATIENTS We identified 1004 patients aged 65 years or older in the Surveillance, Epidemiology and End Results-Medicare database diagnosed with stage IV colon cancer January 1, 1991 to December 31, 2005, who were later hospitalized for bowel obstruction. MAIN OUTCOME MEASURES We describe outcomes after hospitalization and analyzed the associations between surgical treatment of obstruction and outcomes. RESULTS Hospitalization for bowel obstruction occurred a median of 7.4 months after colon cancer diagnosis, and median survival after obstruction was approximately 2.5 months. Median hospitalization for obstruction was about 1 week and in-hospital mortality was 12.7%. Between discharge and death, 25% of patients were readmitted to the hospital at least once for obstruction, and, on average, patients lived 5 days out of the hospital for every day in the hospital between obstruction diagnosis and death. Survival was 3 times longer in those whose obstruction claims suggested an adhesive obstruction origin. In multivariable models, surgical compared with nonsurgical management was not associated with prolonged survival (p = 0.134). LIMITATIONS Use of an administrative database did not allow determination of quality of life or relief of obstruction as an outcome, nor could nonsurgical interventions, eg, endoscopic stenting or octreotide, be assessed. CONCLUSIONS In this population-based study of patients with stage IV colon cancer who had bowel obstruction, overall survival following obstruction was poor irrespective of treatment. Universally poor outcomes suggest that a diagnosis of obstruction in the setting of advanced colon cancer should be considered a preterminal event.

Abstract
BACKGROUND Small-bowel obstruction (SBO) represents as many as 16% of surgical admissions and more than 300,000 operations annually in the United States. The optimal strategies for the diagnosis and management of SBO continue to evolve secondary to advances in imaging techniques, critical care, and surgical techniques. This updated systematic literature review was developed by the Eastern Association for the Surgery of Trauma to provide up-to-date evidence-based recommendations for SBO. METHODS A search of the National Library of Medicine MEDLINE database was performed using PubMed interface for articles published from 2007 to 2011. RESULTS The search identified 53 new articles that were then combined with the 131 studies previously reviewed by the 2007 guidelines. The updated guidelines were then presented at the 2012 annual EAST meeting. CONCLUSION Level I evidence now exists to recommend the use of computed tomographic scan, especially multidetector computed tomography with multiplanar reconstructions, in the evaluation of patients with SBO because it can provide incremental clinically relevant information over plains films that may lead to changes in management. Patients with evidence of generalized peritonitis, other evidence of clinical deterioration, such as fever, leukocytosis, tachycardia, metabolic acidosis, and continuous pain, or patients with evidence of ischemia on imaging should undergo timely exploration. The remainder of patients can safely undergo initial nonoperative management for both partial and complete SBO. Water-soluble contrast studies should be considered in patients who do not clinically resolve after 48 to 72 hours for both diagnostic and potential therapeutic purposes. Laparoscopic treatment of SBO has been demonstrated to be a viable alternative to laparotomy in selected cases.

Abstract
Several options exist to palliate malignant obstruction (MBO), none of which have established consensus among surgeons. The purpose of this study was to establish outcomes of diverting stoma (DS), internal bypass (IB), and palliative resection (PR) for a tertiary academic referral surgical oncology service. All patients presenting to a surgical oncology service with malignant bowel obstruction over a 3-year period were identified. Records were reviewed to determine success of diversion, bypass, or resection and associated cost, length of stay (LOS), morbidity, and mortality. Forty-three patients undergoing palliative surgery were identified. The success of each approach was 80, 78, and 63 per cent for diversion, bypass, and resection, respectively. Major morbidity (63%), mortality (16%), and LOS (26 days) were greatest in those undergoing PR, but so was survival (8.4 months). DS and IB had comparable morbidity (40 and 33%), mortality (10 and 0%), and LOS (25 and 21 days), but survival was shorter for DS (5.3 vs 6.5 months). Cost of PR was significantly greater ($79,000) than both DS ($36,000) and IB ($51,000). Escalation in complexity of palliative measures for MBO results in improved survival but at significant cost both economically and physiologically. Quality of life should be discussed with patients when deciding how best to palliate their symptoms.

Abstract
Proper indications for a second surgical intervention in patients with colorectal cancer have always been a controversial subject. Surgeons find benefit in a second-look operation where a limited extent of cancer is discovered and resected with negative margins. However, a negative exploratory laparotomy or an intervention that is unable to achieve an R0 resection provides little or no benefit. Unfortunately, this type of intervention may place the patient in a worse condition, leading to morbidity or mortality. This manuscript attempts to define clinical parameters of primary colorectal cancer that are associated with a pattern of recurrence and that can be definitively addressed by second-look surgery. Also, new surgical technologies that may assist in achieving a potentially curative resection of local-regional recurrence are described. Cytoreductive surgery with peritonectomy and perioperative intraperitoneal chemotherapy with hyperthermia is presented as a new treatment option for reoperative surgery. A new management plan utilized in patients at high risk for local-regional recurrence may result in a high likelihood of conversion of a second-look cancer-positive patient to a long-term survivor.

Abstract
Patients with advanced gynecologic malignancies have a multitude of symptoms; pain, nausea, and vomiting, constipation, anorexia, diarrhea, dyspnea, as well as symptoms resulting from intestinal obstruction, hypercalcemia, ascites, and/or ureteral obstruction. Pain is best addressed through a multimodal approach. The optimum palliative management of end-stage malignant intestinal obstruction remains controversial, with no clear guidelines governing the choice of surgical versus medical management. Patient selection for palliative surgery, therefore, should be highly individualized because only carefully selected candidates may derive real benefit from such surgeries. There remains a real need for more emphasis on palliative care education in training programs.

Abstract
Proper indications for second-look surgery in patients with colorectal cancer have always been a controversial subject. The surgical literature suggests benefit in a reoperation, where a limited extent of cancer is discovered and then resected with negative margins. However, patients are often subjected to a negative exploratory laparotomy or an intervention that is unable to achieve an R-0 resection; in these circumstances, little or no benefit occurs. Unfortunately, an unsuccessful repeat intervention may place the patient in a worse condition, especially if morbidity occurs. This paper seeks to identify the clinical parameters of a primary colorectal cancer and a followup plan that are associated with cancer recurrence that can be definitively addressed by the second look surgery. New surgical technologies, including cytoreductive surgery with peritonectomy and perioperative intraperitoneal chemotherapy with hyperthermia, are suggested for use in this group of patients. This new management strategy used in patients with local-regional recurrence may result in a high proportion of patients converted from a second-look positive patient to a long-term survivor.

Abstract
The timing of reoperation for small bowel obstruction is a topic of significant debate. Any patient with evidence of strangulation should undergo urgent surgical intervention. However, predicting strangulation can be difficult. Because of this, previous authors have recommended everything from emergency operation for all patients presenting with small bowel obstruction to periods of observation that extend up to 14 days. Over the past century, the primary etiology of small bowel obstruction has shifted from hernias to postoperative adhesive disease, leading to a shift in the management paradigm. To manage small bowel obstruction successfully today, the clinician must distinguish the patient requiring urgent operation from those who benefit from nonoperative management. Furthermore, the clinician must be able to determine the appropriate length of time for conservative management. In this article we review the significant body of literature on this topic including the diagnostic workup and timing of potential operative intervention in the patient with small bowel obstruction.

Abstract
BACKGROUND A malignant bowel obstruction (MBO) is a common clinical complication in patients with recurrent gastrointestinal carcinoma, which has a poor prognosis and a limited life expectancy. This study considered the effectiveness of surgical management for MBO. METHODS This study reviewed the clinical course of 70 patients who underwent surgery for MBO and compared the outcomes in three groups: patients with (A) peritonitis carcinomatosis without manifest ascites, (B) peritonitis carcinomatosis with ascites, (C) local recurrence without peritonitis carcinomatosis. RESULTS The 1-year survival rate and median survival time (MST) in the patients in group A were 33.3% and 228 days, which was statistically longer than those (6.7% and 46 days) in the patients in group B (P = 0.026). The rate of the patients with possible oral intake of solid meals for 6 months and median oral intake periods were 45.4% and 161 days in patients in group A and 28.0% and 93 days in patients in group C. In contrast, 66.7% in group B could not take solid meals for more than 1 month, and five patients could not take solid meals at all. CONCLUSION Palliative operations for the patients with manifest ascites of MBO are risky and rarely effectively improve oral intake, but this is not considered to be a contraindication for surgical management. Informed consent is therefore important in the surgical management of MBO.

Abstract
The management of malignant bowel obstruction is a challenging problem because of the poor definition of malignant bowel obstruction compounded by its myriad clinical presentations. Surgeons are called upon to perform invasive procedures designed to alleviate symptoms or correct the underlying obstruction. Unfortunately, interventions may carry a high rate of morbidity and mortality. Balancing these risks and potential benefits is complicated, and there is a paucity of data to help guide these difficult decisions. The surgeon is further handicapped when he or she is not understanding of the patient's disease status, prognosis, or long-term goals. Diligent discussion with the primary team and frank discussions with the patient and his or her family are essential to formulate an appropriate plan. It is also essential that the surgeon have a thorough understanding of the surgical options to relieve or palliate malignant bowel obstruction as well as effective nonsurgical interventions. The best approach may be appropriate surgical intervention coupled with aggressive medical management.

Efficacy of granisetron in the antiemetic control of nonsurgical intestinal obstruction in advanced cancer: a phase II clinical trial. J Pain Symptom Manage 2009; 37:259-70.

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

Abstract
Background Resection of peritoneal metastases has been shown to improve survival in patients with abdominal metastatic disease from abdominal or extra abdominal malignancy. This study evaluates the benefit of peritoneal metastatic resection in patients with malignant small bowel obstruction and a past history of treated cancer. Patients and methods Patients undergoing laparotomy for resection of peritoneal metastases from recurrence of previous cancer between 1992–2003 were reviewed retrospectively. Data were collected about type of primary cancer, interval to recurrence, extent of the disease and completeness of resection, morbidity and mortality and long-term survival. Results Between 1992 and 2003 there were 79 patients (median age 62, range 19–91) who had laparotomy for small bowel obstruction due to recurrent cancer. The primary cancer was colorectal (31), gynaecologic cancer (19), melanoma (16) and others (13). Overall, the rate of complications was 35% and mortality was 10%. Median survival was 5 months; patients with history of colorectal cancer had better survival than other cancer (median survival 7 months vs. 4 months; p = 0.02). Multivariate analysis showed that the extent of recurrent disease was the only factor that affected overall survival. Conclusion Laparotomy for small bowel obstruction is a worthwhile option for patients with malignant small bowel obstruction. Although it is associated with significant morbidity and mortality it offers a reasonable survival benefit in particular for patients with completely resectable disease.

Abstract
OBJECTIVE To compare the diagnostic performance of axial and coronal views in multidetector-row computed tomography (MDCT) of patients with small-bowel obstruction (SBO) or large-bowel obstruction (LBO). MATERIALS AND METHODS Among 157 patients with clinical and radiographic findings of BO, 73 patients, who underwent MDCT and were found to have surgically proven SBO (49/73) or LBO (24/73), were retrospectively evaluated. Portal-enhanced MDCT was performed using 4 x 2.5-mm collimation; 3-mm-thick axial images were reconstructed with 2 mm of increment. Coronal views were reformatted using 3-mm-thick sections with 1 mm of increment. Three radiologists analyzed axial (session A), coronal (session B), and axial plus coronal images (session C) to identify the site, cause, and type of BO. To correlate surgical findings and MDCT results, the bowel was divided into duodenum, oral jejunum, aboral jejunum, oral ileum, aboral ileum, cecum/ascending colon, transverse colon, descending colon, and sigmoid colon/rectum. The mean diagnostic accuracy and the mean confidence score of each reader and each reading session were calculated. RESULTS The diagnostic accuracy of axial images was higher than that of coronal views (P = 0.014) in SBO, whereas no significant differences were found in LBO. The definition of the SBO cause was correctly assessed in 45 of 49 patients during session A, in 40 of 49 during session B, and in 45 of 49 during session C. In patients with LBO, the cause was correctly assessed in 21 of 24 patients during session A and in 22 of 24 patients during sessions B and C. All readers interpreted axial plus coronal images with a significantly higher confidence level than axial or coronal views alone, either for the detection of the site (P = 0.002) or for the identification of the cause (P < 0.001) of SBO and LBO. CONCLUSION The MDCT allowed accurate detection of the site and the cause of obstruction. In SBO, axial images yielded a higher diagnostic accuracy than coronal views, whereas in LBO, no differences were found between axial and coronal planes. The reading of axial plus coronal views significantly improved diagnostic confidence.

Surgery as a bridge to palliative chemotherapy in patients with malignant bowel obstruction from colorectal cancer. Ann Surg Oncol 2007; 14:1264-71. [PMID: 17235711 DOI: 10.1245/s10434-006-9303-6] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2006] [Revised: 07/18/2006] [Accepted: 07/20/2006] [Indexed: 11/18/2022]
Abstract
BACKGROUND Malignant bowel obstruction (MBO) is a feature of the clinical course of 10-28% of colorectal cancer (CRC) patients and is associated with a poor prognosis. Recent advancements in palliative chemotherapy regimens have prolonged survival in patients with stage IV CRC. Few reports exist that describe outcomes in patients who have had surgery for MBO and subsequent chemotherapy as part of their treatment. The objective of this study was to review surgical outcomes in patients with MBO for CRC and to evaluate the extent to which surgery can serve as a bridge to palliative chemotherapy. METHODS Patients who presented with MBO and had surgical treatment were identified from a prospectively kept database at a single tertiary care center between 09/99 and 08/04. Charts were retrospectively reviewed and clinical and outcomes data were abstracted. RESULTS Forty-seven patients were identified who had surgery as part of the treatment for MBO from CRC. Operations included resections, bypasses and stoma creation. Overall, 80% of patients were able to tolerate solid food post-operatively and return home. The median survival for the entire cohort was 3.5 months. Seven patients died within 30 days of surgery. Of the remainder, 24 patients were palliated with surgery alone and 16 patients ultimately received palliative chemotherapy. Survival in the final cohort was significantly prolonged (P < 0.001). CONCLUSION Surgery can adequately palliate a substantial proportion of patients with MBO from CRC with acceptable morbidity and mortality. In addition, in a subset of patients it can facilitate palliative chemotherapy that is associated with improved overall survival.

Abstract
Achieving the best quality of life for patients and their families when a disease becomes progressive and no longer remains responsive to curative therapy is the primary goal of palliative care. A comprehensive care plan focusing on control of physical symptoms as well as psychological, social, and spiritual issues then becomes paramount in that context. Symptom assessment and treatment are a principle part of palliative care. This paper is the first of three in a series addressing non-pain symptoms, which are frequently encountered in the palliative care populations. The most frequent non-pain symptoms are constipation, chronic nausea and vomiting, anorexia, dyspnea, fatigue, and delirium. As symptoms are subjective, their expression varies from patient to patient, depending on the individual patient's perception and on other factors such as psychosocial issues. While symptoms are addressed individually, patients frequently have multiple coexisting symptoms. Generally told, once the intensity of a symptom has been assessed, it is necessary to assess the symptom in the context of other symptoms such as pain, appetite, fatigue, depression, and anxiety. Given that fact, adopting a multidimensional assessment allows for formulation of a more effective therapeutic strategy. More pertinently, this paper highlights the management of non-pain symptoms as an integral part of patient care and reviews the pathophysiologies, causes, assessment, and management of constipation, chronic nausea, and vomiting, each of which is common among the palliative care population.

Abstract
Impaired intestinal passage considerably reduces quality of life irrespective of the underlying condition. Limited life expectancy and increased operative risk of advanced malignant disease add particular weight to this issue. The indication for operative therapy results from carefully weighing individual incapacity and potential gain vs operative risk and life expectancy. Exactly because life expectancy is quite limited, selection of an effective, low-risk procedure is of utmost importance to benefit the patient.

Abstract
The last phases of colorectal malignant illness may be the most challenging and saddening for all involved, but they offer opportunities to become the most rewarding. This transformation of hopelessness to fulfillment requires a willingness by surgeon, patient, and patient's family to trust one another to realistically set goals of care, stick together, and not let the treatment of the disease become a surrogate for treating the suffering that characterizes grave illness.

Abstract
BACKGROUND Both surgical and nonsurgical options are available to treat bowel obstruction in patients with metastatic cancer. The goal is straightforward: to restore bowel patency and palliate the symptoms of obstruction. Yet the most appropriate management is often a challenging decision. AIM OF THE STUDY We sought to review our experience in managing patients with metastatic cancer and bowel obstruction. METHODS A retrospective review was performed to identify all patients admitted at University of Wisconsin Hospital between 1993 and 2000 with the diagnoses of both bowel obstruction and metastatic cancer. Demographic data, type of management, postoperative complications, and outcome were analyzed. RESULTS A total of 114 patients with primarily colorectal or gynecologic malignancies were identified. Patients' first bowel obstructions were managed in one of two ways: (1) definitive surgical intervention (n = 47), or (2) conservative management (n = 67). The median overall survival was 3 mo for the entire study group. There was no significant difference in overall or obstruction-free survival based on management, presence of recurrent bowel obstruction, or type of primary cancer. The only factor that was significant in predicting poor overall survival included a disease-free interval of less than 1 yr (time of diagnosis of primary cancer to time of bowel obstruction, p = 0.002). CONCLUSIONS Bowel obstruction in patients with metastatic cancer is a terminal event, with a 3-mo median survival. Because there is no difference in overall or obstruction-free survival based on management, the treatment for palliation of bowel obstruction in patients with metastatic cancer should be individualized.

Advanced abdominal imaging is not required to exclude strangulation if complete small bowel obstructions undergo prompt laparotomy. J Am Coll Surg 2005; 200:904-11.

Abstract
BACKGROUND When small bowel obstruction is demonstrated clinically or radiographically to be complete, operation is advocated because of the demonstrated association of strangulation obstruction with complete obstruction and the difficulty of diagnosing strangulation obstruction. Short observation periods, fluoroscopic procedures, and cross-sectional imaging are used in treatment of partial obstruction by those who believe that observation is futile or dangerous. This approach holds that few patients resolve after a day or two of observation; if this premise were true, protracted observation should see few patients resolve and some require resection for necrotic bowel after failed observation. Observer bias and the spectrum of nonnecrotic ischemia makes end-point analysis after laparotomy difficult to interpret; few criteria or incentives exist for a surgeon to speculate that a patient brought to surgery might have recovered without it. STUDY DESIGN I reviewed the clinical courses of 413 obstructed patients seen over 13 years. RESULTS Seventy-two patients underwent immediate treatment for complete obstruction, 294 resolved without operation, and 47 patients required operation after a period of observation ranging from 3 to 15 days. All observed patients were followed using clinical examination, leukocyte count, and plain film radiography only. No bowel resections were required in patients who were observed. CONCLUSIONS Research opportunities exist for use of alternatives to plain film imaging in treatment of partial small bowel obstruction, but this series does not support the premise that there is a risk for bowel ischemia or bowel resection by observing patients with partial small bowel obstruction or by following them with plain films alone. Indeed, such a strategy resulted in resolution in 294 of 341 patients so treated, with readmission and reoperation rates comparable with those reported in series in which earlier operation was undertaken.

Abstract
OBJECTIVE To evaluate the usefulness and reliability of helical computed tomography (CT) for patients with small bowel obstruction. METHODS AND MATERIAL Helical CT findings of 41 patients were evaluated prospectively on the basis of the presence and the cause of obstruction, and the presence of strangulation. RESULTS In the determination of the cause of the obstruction sensitivity and specificity of CT were 84 and 90%, respectively. Of the 19 patients undergoing surgery, 6 had strangulation and were correctly identified by CT. CONCLUSION Helical CT is an accurate method in the detection of small bowel obstruction, especially for evaluating the cause and vascular complications of obstruction.

Abstract
BACKGROUND AND OBJECTIVES The optimal management of symptomatic advanced peritoneal carcinomatosis of non-gynecologic origin is not defined. Historic controls of surgical efforts report high postoperative mortality and morbidity rates with equivocal palliation. Novel surgical procedures need to be tested in terms of the impact on survival and quality of life. STUDY DESIGN We studied 46 consecutive patients who underwent total abdominal colectomy, pelvic peritonectomy with construction of an end-ileostomy for palliation of peritoneal carcinomatosis. RESULTS Total abdominal colectomy, pelvic peritonectomy, and end-ileostomy was successfully performed in 46 patients of median age of 54.4 years. Overall median survival was 10.7 months, with a mean follow-up period of 12 months. Patients with appendiceal malignancy had a median survival of 19.7 months. Prognosis was poorer for patients with colon cancer, who had a median survival of 7.0 months, while patients with primary peritoneal carcinomatosis had a median of 7.8 months. Postoperative morbidity and mortality rates were 19.5 and 8.6%, respectively. CONCLUSIONS Total abdominal colectomy, pelvic peritonectomy, and end-ileostomy is a technically feasible procedure and is advocated for the palliation of patients with peritoneal carcinomatosis of appendiceal origin. It is not clear if the procedure should be advocated for more invasive gastrointestinal malignancies.

Abstract
Bowel obstruction may be a mode of presentation of intra-abdominal and pelvic malignancy or a feature of recurrent disease following anticancer therapy. Malignant bowel obstruction is well-recognized in gynecologic patients with advanced cancer. Retrospective and autopsy studies found the frequency at approximately 5-51% of patients with gynecological malignancy(1-7). Malignant bowel obstruction (MBO) is particularly frequent in patients with ovarian cancer where it is the most frequent cause of death(7). Patients with stage III and IV ovarian cancer and those with high-grade lesions are at higher risk for MBO as compared to patients with lower stage or low-grade tumors(1,8). Ovarian carcinoma accounted for 50% of small bowel obstruction and 37% of large bowel obstruction treated in a large gynecological oncology service(8-11).

Abstract
Patients with bowel obstruction due to advanced cancer often have a poor prognosis and suffer distressing symptoms that can be difficult to manage. Research to date has focused on medical interventions and the measurement and control of symptoms. Little attention has been given to patients' perceptions of their quality of life or the impact of their illness. This study aimed to explore patients' lived experience of bowel obstruction. Semi-structured interviews were conducted with ten patients with bowel obstruction due to gynaecological or gastric cancer. Data analysis was based on an adaptation of Giorgi (1975) and Parse et al's (1985a,b) phenomenological method. Findings suggest that the 'meaning' of being unable to eat is more significant for patients than the nutritional or biological loss of food. For some patients, bowel obstruction marks a process of transition from life to death which is characterized by a sense of social disengagement and disrupted identity. Interviews highlighted aspects of the nurse-patient relationship that were therapeutic in their own right.

Abstract
BACKGROUND Malignant bowel obstruction (MBO) secondary to peritoneal carcinomatosis carries a grave prognosis. We evaluated clinicopathologic factors that predict outcomes after palliative operations for MBO. METHODS Data on patients undergoing laparotomy for palliation of gastrointestinal MBO at City of Hope between 1995 and 2000 were retrospectively collected. Successful palliation was defined as the ability to tolerate solid food (TSF). RESULTS Sixty-three patients underwent operative treatment. In 20 patients, MBO was the first presentation of disease; for others, the median disease-free interval was 15 months. The complication rate was 44%, and postoperative mortality was 15%. The median length of stay was 12 days. Twenty-nine patients (45%) were discharged from the hospital on a regular diet; 22 (76%) continued to eat until their last follow-up. Median survival was 90 days. Univariate factors for longer survival were TSF on discharge, colorectal primary, and nonmetastatic status at first diagnosis. Patients with ascites and whose cancer first presented with MBO had an inferior survival. Noncolorectal primary remained a multivariate predictor for decreased survival. TSF was predicted by the absence of ascites, an obstruction not involving the small bowel, and a preoperative albumin of >3.0 mg/dl. Multiple logistic regression analysis yielded presence of ascites and small-bowel obstruction as predictors of inability to TSF. CONCLUSIONS Only one third of patients with MBO from peritoneal carcinomatosis will have prolonged postoperative palliation with significant, but acceptable, treatment-related morbidity. TSF at discharge is a useful predictor of continued palliation for most patients. Patients with colorectal cancer may have superior survival outcome and better palliation; others are at risk for poor outcomes, especially in the presence of ascites and MBO of small bowel. In these patients, highly selective use of laparotomy is recommended.

Abstract
BACKGROUND Gastrointestinal and ovarian cancers are common cancers. The incidence of associated malignant bowel obstruction in patients with advanced cancers of these types is not known, and the best management of these patients is controversial. Inappropriate management may result in uncontrolled (faeculant) vomiting, pain and distress. Management of the symptoms can include palliative surgery, nasogastric tube suction together with intravenous fluids, or pharmacological means, such as corticosteroids. There is uncertainty regarding both the efficacy and possible harmful effects of corticosteroids, and also the most effective type, dose/dosing regime, route and period of administration. OBJECTIVES To locate, appraise and summarise evidence from scientific studies on intestinal obstruction due to advanced gynaecological and gastrointestinal cancer, in order to assess the efficacy of corticosteroids. SEARCH STRATEGY A comprehensive list of all studies was provided by an extensive search of the electronic databases, relevant journals, reference lists, the grey literature, contact with investigators and other search strategies outlined in the methods. SELECTION CRITERIA As the review concentrates on the 'best evidence' available of the role of corticosteroids in malignant bowel obstruction due to advanced gynaecological and gastrointestinal cancer the inclusion criteria were kept fairly broad so as to include all studies relevant to the question DATA COLLECTION AND ANALYSIS Data extraction forms were used to collect data from the studies included in the review. The data was checked by a secondary searcher to reduce error. A qualitative analysis was performed of the dichotomous data of resolution of obstruction and death at one month, obtained from the randomised controlled trials of corticosteroids versus placebo. Both fixed and random effect models were used. Number needed to treat (NNT) was derived from the odds ratio. Kaplan-Meier survival curves from individual patient data were also analysed. Studies of lower methodological quality were assessed in a qualitative manner. MAIN RESULTS Three unpublished, randomised, placebo, double blind controlled trials and seven published (prospective and retrospective) trials were considered eligible. Using only the randomised trials, there is a trend, which is not statistically significant, for the resolution of bowel obstruction using corticosteroids. There is no statistically significant difference in mortality at one month, nor in the Kaplan-Meier curves, which describe the survival of patients on corticosteroids or placebo. Number needed to treat is 6 (3, infinity) ie six patients need to be treated with corticosteroids to resolve one episode of bowel obstruction. The results are robust to fixed and random effects models and to 'best' and 'worst case' scenarios on the missing data from patients. The morbidity associated with corticosteroids appears to be very low, though the quality of the data limits this conclusion. No other outcomes were available from the published data or from the authors. REVIEWER'S CONCLUSIONS There is a trend for evidence that corticosteroids of dose range 6-16 mg dexamethasone given intravenously may bring about the resolution of bowel obstruction. Equally, the incidence of side effects in all the included studies is extremely low. Corticosteroids do not seem to affect the length of survival of these patients.

Abstract
BACKGROUND Intestinal obstruction commonly occurs in progressive advanced gynaecological and gastrointestinal cancers. Management of these patients is difficult due to the patients deteriorating mobility and function (performance status), the lack of further chemotherapeutic options and the high mortality and morbidity associated with palliative surgery. There are marked variations in clinical practice concerning surgery in these patients between different countries, gynaecological oncology units, and general hospitals as well as referral patterns from oncologists under whom these patients are often admitted under. There is therefore a need for all the present information to be collated, analysed (with appropriate palliative care outcomes) to establish if surgery is of benefit and what further research is needed. OBJECTIVES The objective was to locate, appraise and summarise evidence from scientific studies on intestinal obstruction due to advanced gynaecological and gastrointestinal cancer, in order to assess the efficacy of surgery. SEARCH STRATEGY A comprehensive list of studies was provided by an extensive search of electronic databases, relevant journals, bibliographic databases, conference proceedings, reference lists, the grey literature, personal contact and the world wide web. SELECTION CRITERIA As the review concentrates on the 'best evidence' available of the role of surgery in malignant bowel obstruction in advanced gynaecological and gastrointestinal cancer the inclusion criteria were kept broad (included both prospective and retrospective studies) so as to include all studies relevant to the question. DATA COLLECTION AND ANALYSIS Data extraction forms were used to collect data from the studies included in the review. Two researchers extracted the data independently to reduce error. Due to the methodological quality of the studies, only a qualitative assessment was possible. MAIN RESULTS The role of surgery in malignant bowel obstruction remains controversial, and no firm conclusions from the many retrospective case series can be made. Control of symptoms varies from 42% to over 80%, though it is often unclear how symptoms were measured and whether the tools used to collect symptom scores are validated. There is a large range in the rates of re-obstruction, from 10-50%, though time to re-obstruction was often not included. There is a wide range of postoperative morbidity and mortality, although again the definition of both these surgical outcomes varied between many of the papers. REVIEWER'S CONCLUSIONS The role of surgery in malignant bowel obstruction needs careful evaluation, using validated outcome measures of symptom control and quality of life scores. Further information would include re-obstruction rates together with the morbidity associated with the various surgical procedures. Currently, bowel obstruction is managed empirically, and there are marked variations in clinical practice by different units. There needs to be a greater standardisation of management so that comparisons between different series can be made.

Abstract
OBJECTIVE Women with recurrent gynaecological cancers who are not suitable for exenterative surgery commonly present with gastrointestinal dysfunction. This paper is a retrospective review of the use of gastrostomy tubes in such women. METHODS We performed a chart review of women with recurrent gynaecological cancer who had a gastrostomy tube placed between January 1991 and April 1998. RESULTS Thirty-nine women (mean age 53.2 years, range 17-82) had a gastrostomy tube placed. Twenty-eight (72%) had ovarian cancer, eight (21%) had cervical cancer, two had endometrial cancer and one had vaginal cancer. In 14 women a gastrostomy tube was placed as the sole procedure for palliation (11 elective, 3 emergency). In the remaining 25 women, who underwent major surgery, a gastrostomy tube was placed in anticipation of, or in the presence of, significant intestinal distension and expected prolonged post-operative ileus. Eleven women (28%) died without leaving hospital after their operation (median 11 days, range 2-36). All but one of the 28 women who left hospital had satisfactory oral intake. Twenty-one women (54%) died with the gastrostomy tube in place (median 28 days, range 2-157) and 18 (46%) had the gastrostomy tube removed (median 14.5 days, range 9-180), 13 of whom (33%) have since died (median 167 days, range 77 days-7 years). Five women (13%) are alive (median 2.2 years, range 10 months-4.5 years). There were no problems which required the gastrostomy tube to be removed. CONCLUSION Gastrostomy tubes have an important role in the treatment of women with recurrent gynaecological cancer, allowing gastric drainage and decompression without the disadvantages of nasogastric tubes.

Abstract
OBJECTIVE The purpose of this study was to evaluate the usefulness of CT in determining the causes of intestinal obstruction in patients who have undergone abdominal surgery for malignancy. MATERIALS AND METHODS We analyzed the CT scans of 55 patients with benign (n = 26) or malignant (n = 29) intestinal obstruction that developed after abdominal surgery for malignancy. After calculating the diagnostic accuracy of interpretations by three radiologists, we compared CT findings for benign and malignant intestinal obstructions with respect to peritoneal involvement patterns and other ancillary findings. Multivariate logistic regression analysis was used to determine the diagnostic performance of CT in revealing causes of obstruction. RESULTS Diagnostic accuracies of the three radiologists were 67%, 75%, and 78%. CT findings indicating malignant obstruction were a mass at the site of obstruction or prior surgery, lymphadenopathy, or an abrupt transition zone and irregular bowel wall thickening at obstructed sites (p < .05). Conversely, the chance for benign obstruction increased when CT revealed mesenteric vascular changes, a large amount of ascites, or a smooth transition zone and smooth bowel wall thickening at the obstructed site (p < .05). With multivariate logistic regression analysis using two variables (a mass at the site of obstruction or prior surgery and lymphadenopathy), we calculated the overall accuracy of CT as 84% (46/55 patients). CONCLUSION CT is useful in differentiating benign from malignant intestinal obstructions in patients who have undergone abdominal surgery for malignancy. However, CT has limitations in patients not having a demonstrable peritoneal mass.

Abstract
In this second article in the series, obstruction of hollow viscera in patients with advanced malignant disease is discussed. The obstruction of such structures can be associated with the development of painful and incapacitating symptoms, often in patients who have a limited life expectancy. This obstruction may be caused by the primary tumour, compression from adjacent tumour-draining lymph nodes, the presence of metastases distant from the site of the primary tumour or to adhesions within the abdominal compartment (usually as a result of previous surgery). The organs most often affected are the oesophagus, the intestine (small and large), the biliary tree and the genito-urinary tract. Obstruction of each of these organs and its management is discussed in more detail below.

Abstract
Reoperative surgery was used as a treatment for patients with recurrent obstructing cancer. In this group of patients intraperitoneal chemotherapy was used in an attempt to prolong the beneficial effects of treatment. This aggressive approach may be recommended irrespective of patient performance status if the patient is not terminally ill. This treatment was associated with a high rate of postoperative complications (55%) but low mortality (7%). To avoid or reduce the incidence of postoperative complications, this treatment should be performed only by an experienced surgical oncologist. Long-term benefits of this treatment were related to biologic factors reflected by cancer origin in the appendix, low-grade tumor histopathology, and a free interval of > 2 years. Treatment-related factors were completeness of cytoreduction and administration of intraperitoneal chemotherapy. The best outcome was achieved with pseudomyxoma peritonei of appendiceal origin with a time interval between surgeries of 2 or more years, a complete cytoreduction, and treatment with intraperitoneal chemotherapy. This treatment modality can be recommended for palliation of patients with recurrent obstruction due to other gastrointestinal and ovarian malignancies, although, long-term results may not be so encouraging as with appendix tumors. In the group of colorectal cancer patients treated by aggressive reoperative surgery and intraperitoneal chemotherapy, 35.3 percent survived 1 year, which differs significantly from the 4-5 month survival after treatment by the standard approach.

Abstract
BACKGROUND Many cases of acute adhesive small-bowel obstruction (SBO) can be successfully treated with intestinal tube decompression. There is considerable controversy, however, regarding whether a short nasogastric tube (NGT) or a long nasointestinal tube (LT) is the best method of intestinal tube decompression. PATIENTS AND METHODS A prospective, randomized trial was conducted to compare NGT and LT decompression with respect to the success of nonoperative treatment and morbidity of surgical intervention in 55 patients with acute adhesive SBO. RESULTS Twenty-eight patients were managed with NGT and 27 with LT. There were 44 cases of partial SBO (23 NGT, 21 LT) and 11 cases of complete SBO (5 NGT, 6 LT). Twenty-one patients ultimately required operation, including 13 managed with NGT (46%) and 8 with LT (30%) (P = 0.16). The mean period between admission and operation was 60 hours in the NGT group versus 65 hours in the LT group. At operation, 3 patients in the NGT group had ischemic bowel that required resection. Postoperative complications occurred in 23% of patients treated with NGT versus 38% of patients treated with LT (P = 0.89). Postoperative ileus averaged 6.1 days for NGT patients versus 4.6 days for LT patients (P = 0.44). There were no deaths. CONCLUSIONS Patients with adhesive SBO can safely be given a trial of tube decompression upon hospital admission. There was no advantage of one type of tube over the other in patients with adhesive SBO.
