How Predictive are the Signs and Symptoms of Small Bowel Obstruction.

ABSTRACT: OBJECTIVE: The present study aims to determine the diagnostic significance of signs and symptoms of Small Bowel Obstruction (SBO) and to ascertain if there was any delay in presentation of the patients to the hospital. METHODS: This retrospective case study spanning 3 years was conducted at Riyadh Medical Complex, Saudi Arabia. All adult patients admitted from the ER with a diagnosis of SBO were included in the study. The medical records of the patients with International Classification of Diseases (ICD) 9 codes 552.8, 560, 560.8, 560.81 and 560.9 were searched and retrieved. RESULTS: A total of 195 patients were included in the study out of which 174 patients had a definitive diagnosis of SBO. The study group was composed of 76.4% males and 71.8% were aged between 20 years to 60 years. The mean duration of symptoms was 4.8 days, ranging from 6 hours to 17 days. The cardinal signs and symptoms of obstruction had low sensitivity (Range: 56-75), and specificity (Range: 28-61), but relatively high positive predictive value (PPV) (Range: 86-93). The morbidity was 13.8% while mortality was 3.4%. CONCLUSION: The cardinal features of SBO are neither specific nor sensitive, and though they may have an acceptable PPV, the predicted rate of false positive diagnosis is unacceptable. Therefore, the clinician may not rely on the clinical picture alone for the diagnosis of SBO. The presentation of the studied patients was delayed compared to the literature and it may be an important factor in increasing morbidity and mortality, but this aspect needs to be studied further.

Unenhanced CT-based predictive model to identify small bowel necrosis in patients with mechanical small bowel obstruction.

Project description:ObjectivesTo investigate the diagnostic value of unenhanced CT in mechanical small bowel obstruction (SBO) with small bowel necrosis, and to establish a predictive model.MethodsFrom May 2017 to December 2021, the patients with mechanical SBO admitted to our hospital were retrospectively collected. Taking pathology-confirmed small bowel necrosis as the gold standard, the experimental group was composed of patients with small bowel necrosis confirmed by pathology, and the control group was composed of patients with no intestinal necrosis confirmed by surgery or successful conservative treatment with no recurrence of intestinal obstruction during 1-month followed-up.ResultsA total of 182 patients were enrolled in this study, 157 patients underwent surgery, of which 35 patients were accompanied with small bowel necrosis and 122 patients were not (33 patients with ischemic findings at surgery without necrosis). Finally, there were 35 patients in the experimental group and 147 patients in the control group. Multivariable logistic regression showed that increased attenuation of small bowel wall (P = 0.002), diffuse mesenteric haziness (P = 0.010), difference of CT value between mesenteric vessel and aorta (P = 0.025) and U-/C-shaped small bowel loop (P = 0.010) were independent risk factors for the diagnosis of mechanical SBO with small bowel necrosis. Through internal verification, the area under curve (AUC) of the predictive model reached 0.886 (95%CI: 0.824-0.947), and the calibration result was moderate.ConclusionMultiple features (increased attenuation of small bowel wall; difference of CT values between mesenteric vessel and aorta; diffuse mesenteric haziness; and U-/C-shaped small bowel loop) of unenhanced CT have clinical value in the diagnosis of mechanical SBO with small bowel necrosis. The predictive model based on these four features could achieve satisfactory efficiency.

Small bowel obstruction from migrated intragastric balloon.

Project description:Intestinal obstruction resulted from balloon migration is an extremely rare but serious late complication of the intragastric balloon (IGB). The aim of this study is to report a case of small bowel obstruction occurring in a middle age corpulent female following embedding of IGB. A 47-year-old obese female presented with abdominal pain, nausea, and vomiting for two days. She had a history of an endoscopically placed IGB nine months before presentation. Physical examination showed an obese woman with mild distress, and the right upper abdomen was tender. The plain abdominal radiograph showed gas shadow in the stomach and the duodenum, esophago-gastro-duodenoscopy showed an empty stomach and balloon migration from the stomach. Under general anesthesia, laparotomy was performed, a three-centimeter antimesenteric enterotomy was done and the balloon extracted from the proximal jejunum. Intestinal obstruction is an extremely rare complication of IGB. It should be managed by laparotomy and extraction of the balloon.

UK-based, multisite, prospective cohort study of small bowel obstruction in acute surgical services: National Audit of Small Bowel Obstruction (NASBO) protocol.

Project description:INTRODUCTION:Small bowel obstruction (SBO) is a common indication for emergency laparotomy in the UK, which is associated with a 90-day mortality rate of 13%. There are currently no UK clinical guidelines for the management of this condition. The aim of this multicentre prospective cohort study is to describe the burden, variation in management and associated outcomes of SBO in the UK adult population. METHODS AND ANALYSIS:UK hospitals providing emergency general surgery are eligible to participate. This study has three components: (1) a clinical preference questionnaire to be completed by consultants providing emergency general surgical care to assesses preferences in diagnostics and therapeutic approaches, including laparoscopy and nutritional interventions; (2) site resource profile questionnaire to indicate ease of access to diagnostic services, operating theatres, nutritional support teams and postoperative support including intensive care; (3) prospective cohort study of all cases of SBO admitted during an 8-week period at participating trusts. Data on diagnostics, operative and nutritional interventions, and in-hospital mortality and morbidity will be captured, followed by data validation. ETHICS AND DISSEMINATION:This will be conducted as a national audit of practice in conjunction with trainee research collaboratives, with support from patient representatives, surgeons, anaesthetists, gastroenterologists and a clinical trials unit. Site-specific reports will be provided to each participant site as well as an overall report to be disseminated through specialist societies. Results will be published in a formal project report endorsed by stakeholders, and in peer-reviewed scientific reports. Key findings will be debated at a focused national meeting with a view to quality improvement initiatives.

Bowel Ischemia Score Predicts Early Operation in Patients With Adhesive Small Bowel Obstruction.

Project description:BackgroundNonoperative management of adhesive small bowel obstruction (SBO) is successful in up to 80% of patients. Current recommendations advocate for computed tomography (CT) scan in all patients with SBO to supplement surgical decision-making. The hypothesis of this study was that cumulative findings on CT would predict the need for operative intervention in the setting of SBO.MethodsThis is an analysis of a retrospectively and prospectively collected adhesive SBO database over a 6-year period. A Bowel Ischemia Score (BIS) was developed based on the Eastern Association for the Surgery of Trauma guidelines of CT findings suggestive of bowel ischemia. One point was assigned for each of the six variables. Early operation was defined as surgery within 6 hours of CT scan.ResultsOf the 275 patients in the database, 249 (90.5%) underwent CT scan. The operative rate was 28.3% with a median time from CT to operation of 21 hours (Interquartile range 5.2-59.2 hours). Most patients (166/217, 76.4%) with a BIS of 0 or 1 were successfully managed nonoperatively, whereas the majority of those with a BIS of 3 required operative intervention (5/6, 83.3%). The discrimination (area under the receiver operating characteristic curve) of BIS for early surgery, any operative intervention, and small bowel resection were 0.83, 0.72, and 0.61, respectively.ConclusionThe cumulative signs of bowel ischemia on CT scan represented by BIS, rather than the presence or absence of any one finding, correlate with the need for early operative intervention.

A Rare Cause of Small Bowel Obstruction: A Case Report

Project description:Introduction Small bowel obstruction is a common surgical emergency abdominal condition in clinical practice. Fecalith is one of the rare causative factors, especially phytobezoars. Case Report We report the case of a 66-year-old man admitted with “abdominal pain with vomiting for 1 day.” Enhanced CT of the abdomen suggested incomplete small bowel obstruction. The symptomatic treatment with fasting, fluid replacement, gastrointestinal decompression, and antibiotics was conducted after the patient was admitted to the hospital. After 2 days of treatment, the patient's abdominal pain was not significantly relieved, so a decision was made to perform laparoscopic examination surgery. During surgery, a columnar foreign body was found embedded in the lumen of the small intestine about 10 cm away from the ileocecal region. Combined with the patient's preoperative history of consuming a large number of persimmons, the primary diagnosis of small intestinal fecalith obstruction was considered. We performed an enterotomy to remove the foreign body, and the procedure was uneventful. On postoperative day 7, the patient was successfully discharged. Conclusion When we encounter a patient with intestinal obstruction without a history of surgery in our clinical work, we should take a careful history, especially about the consumption of foods that can cause phytoliths. When a patient has consumed a large amount of food that can cause phytobezoars before the abdominal pain, we should diagnostically consider it as phytobezoars intestinal obstruction, which helps to reduce the incidence of misdiagnosis and allows the patient to receive treatment timely and effectively.

Incomplete small bowel obstruction in a patient with ankylosing spondylitis.

Project description:Small bowel obstruction is a blockage in the small intestine, which is usually caused by adhesion scar tissue, hernia, medication, or malignancy. The symptoms of small bowel obstruction include nausea and vomiting of bile, abdominal distention and obstipation. We present a case of a 61-year-old man with ankylosing spondylitis and scoliosis, who suffered from incomplete small bowel obstruction due to unusual direction of duodenum and externally compressed by liver, gallbladder and pancreas. We gave conservative treatment and inserted a nasojejunal tube for enteral feeding, and the duodenum broke free from the grip of liver, gallbladder and pancreas to its normal anatomical direction. Besides common etiology of small bowel obstruction, unusual body shape and smaller abdominal cavity may cause obstruction due to external compression of neighbor organs. Conservative treatments include gastrointestinal decompression, correction of electrolytes abnormality and nutrition support, while surgical intervention is suggested for the patient without improvement on conservative management.

Wandering spleen causing small bowel obstruction: Laparoscopic surgical treatment (with video).

Project description:IntroductionWandering spleen (WS) is a clinical entity in which the spleen is not located in its normal anatomical site. Few cases have been reported, mainly in women of childbearing age. This condition can be congenital or acquired due to excessive elasticity of the spleen's suspensory ligaments. WS may cause acute complications requiring emergency surgery, especially related to the rotation of its vascular pedicle, leading to chronic or acute ischemia. The aim of the present case is to show a rare complication of WS, small bowel obstruction (SBO), and its management.Presentation of caseWe report the case of a 40-year-old female presenting with abdominal pain, nausea, and vomiting. CT scan showed SBO caused by WS located in the pelvis with an enlarged spleen vascular pedicle (SVP). Laparoscopic exploration, splenectomy, small bowel resection and anastomosis were performed.DiscussionWS may cause chronic or acute complications, mainly linked with enlargement and torsion of SVP, including acute ischemia and spleen necrosis, or compression of the near organs such as small intestine, stomach, pancreas. The diagnosis is based on physical examination, CT scan and blood exams. Generally, the WS's treatment is laparoscopic splenectomy or splenopexy. In case of vital spleen, splenopexy can be performed, in case of not vital spleen, splenectomy should be preferred.ConclusionThis case provides an excellent example of SBO related to WS. In the video, the management of this complex situation is shown. In these cases, splenectomy represents a valuable option.
