Small bowel obstruction caused by a shiitake mushroom: a case report

A 77-year-old male farmer sustained severe abdominal cramping pain for one hour. Contrast-enhanced multidetector computed tomography (MDCT) showed a 5.2 cm, oval lesion with interior mottled gas and slightly hyperdense component in the small bowel loop causing distension of the proximal small bowel loop. CT diagnosis of a bezoar in the small bowel causing bowel obstruction was made. Exploratory laparotomy disclosed a foreign body of soft texture in the jejunum located at 150 cm from the ligament of Treitz. A whole, undigested shiitake mushroom was noted after incision of the bowel. The patient had an uneventful course during the 9 days of hospitalization. The patient had recalled that he did not have any teeth and did not use dentures during eating, and accidentally swallowed the shiitake mushroom 2 days before the incident occurred

Cuando la ileítis de Crohn no es solo ileítis / When Crohn's ileitis is not just ileitis

RESUMEN En una minoría de pacientes con ileítis de Crohn (EC) de larga evolución, la recrudescencia de los síntomas puede representar una neoplasia ileal, con una clínica indistinguible de la enfermedad basal y por ende poco sospechada. Frecuentemente la patología tumoral se diagnostica en la pieza quirúrgica, tras una intervención por hemorragia u obstrucción intestinal. El objetivo de este trabajo es destacar la importancia de un diagnóstico diferencial ante una ileítis terminal en un paciente con EC con mala respuesta a tratamiento médico.

ABSTRACT In a minority of patients with long-standing Crohn's ileitis, the recrudescence of symptoms may represent a neoplasm involving the ileum that is clinically indistinguishable from the baseline disease and therefore poorly suspected. Tumors are often diagnosed in the surgical specimen, after an intervention due to bleeding or bowel obstruction. The aim of this study is to emphasize the importance of the differential diagnoses of terminal ileitis in a patient with CD with poor response to medical treatment.

Resumen: Antecedentes: El objetivo principal de la cirugía bariátrica es la reducción del índice de masa corporal (IMC). La banda gástrica ajustable laparoscópica (BGAL) fue el método más popular por las relativas ventajas sobre otros. Caso clínico: Mujer de 44 años con dolor y distensión abdominal, con antecedente de colocación de una BGAL; se integró diagnóstico de oclusión intestinal secundario a un giro en el tubo del dispositivo, se dio manejo quirúrgico, la paciente presentó adecuada evolución. Conclusión: La oclusión del intestino delgado por el tubo del dispositivo es una complicación seria y poco común para tomarse en cuenta como diagnóstico diferencial en pacientes bariátricos.

Abstract: Background: The main goal of bariatric surgery is the reduction of Body mass index (BMI). Laparoscopic adjustable gastric band (LAGB) was the most popular method due to its relative advantages over others. Clinical case: A 44-year-old woman with abdominal pain and distension, with a history of LAGB placement had a diagnosis of intestinal occlusion secondary to a twist in the device tube, surgical management was given, the patient presented adequate evolution. Conclusion: The occlusion of the small intestine by the tube of the device is a serious and uncommon complication to be considered as a differential diagnosis in bariatric patients.

Gastrostomía descompresiva en obstrucción gastrointestinal maligna: reporte de caso y revisión de la literatura / Decompressive gastrostomy in patients with malignant gastrointestinal obstruction. Case report and literature review

Resumen La gastrostomía descompresiva durante los últimos años ha surgido como una alternativa de manejo para la paliación de síntomas en personas con enfermedad oncológica terminal que desarrollan obstrucción intestinal sin indicación quirúrgica inicial y es refractaria al manejo médico. El objetivo es brindar calidad de vida a través de la restauración de la vía oral. Sus contraindicaciones han variado con el tiempo; sin embargo, han surgido nuevas técnicas que permiten ampliar el espectro de indicaciones de este procedimiento. Se ha descrito que permite apoyar el control de síntomas, el retorno de la persona a su lugar de cuidado y, posiblemente, el reinicio de la vía oral con la intención de mantener la calidad de vida de la persona.

Abstract In recent years, decompressive gastrostomy has emerged as a therapeutic option for people with terminal cancer who experience intestinal obstruction without an initial surgical indication and refractory to medical treatment. The objective is to provide a better quality of life by restoring the oral route. Its contraindications have varied over time; however, new techniques have allowed broadening the spectrum of indications for this procedure. It has been reported that this technique supports symptom control and allows the return of the patients to their place of care. It could also allow restarting the oral route in order to maintain quality of life.

Íleo biliar. Una entidad que perdura en el tiempo / Gallstone ileus: A condition that persists over time

RESUMEN Antecedentes: se define como íleo biliar (IB) la obstrucción mecánica del tubo digestivo por la presencia de uno o más litos biliares. La fisiopatogenia responde a una fístula colecistoduodenal. Material y métodos: estudio descriptivo- retrospectivo entre diciembre de 2017 y enero de 2020 que incluyó 5 casos de IB. Se analizaron: sexo, edad, presentación clínica, utilidad de tomografía computarizada (TC), abordaje y conducta quirúrgica, cirujano actuante, localización de obstrucción, tamaño del lito y mortalidad. Resultados: analizamos 5 pacientes con IB y edad promedio de 66 años. En 4 objetivamos abdomen oclusivo y en uno perforativo. En todos los pacientes se realizó tomografía y el abordaje fue la laparotomía. Se optó por enterolitotomía en 4 y resección intestinal en uno. Hubo un deceso. Conclusión: el IB es un cuadro poco frecuente e insospechado, que predomina en mujeres. La tomografía es el estudio de referencia (gold standard). Factores inherentes al paciente y al equipo tratante determinan el abordaje y la conducta quirúrgica.

ABSTRACT Background: Gallstone ileus is defined as a mechanical obstruction due to impaction of one or more gallstones within the gastrointestinal tract. The pathogenesis is due to the presence of a cholecystoduodenal fistula. Material and methods: We conducted a descriptive and retrospective study of five cases of gallbladder ileus between December 2017 and January 2020. Sex, age, clinical presentation, usefulness of computed tomography scan, surgical approach and treatment, surgeon, site of obstruction, gallstone size and mortality were analyzed. Results: A total of five patients were included; mean age was 66 years. Four patients presented bowel obstruction and one patient had bowel perforation. All the patients underwent computed tomography scan and laparotomy. Enterolithotomy was performed in four patients and one patient underwent bowel resection. One patient died. Conclusion: Gallstone ileus is a rare condition more likely to affect women. Computed tomography scan is the gold standard method for the diagnosis. The surgical approach and strategy will depend on patient-related factors and on the experience of the surgical team.

Clinical characteristics and risk factors of acute mechanical small bowel obstruction in adults / 中华全科医师杂志

Objective:To analyze the clinical characteristics and the risk factors of acute mechanical small bowel obstruction in adults.Methods:The clinical data of 487 adult patients with acute mechanical small bowel obstruction treated in Drum Tower Hospital Clinical College of Nanjing Medical University from June 2010 to December 2020 were retrospectively analyzed. There were 259 cases of strangulated obstruction (strangulation group) and 228 cases of non-strangulated obstruction (simple group). The cases in the strangulation group were confirmed by operation or pathology, the cases in the simple group were confirmed by non-operative therapy ( n=167) or operation ( n=61). The clinical data, including age, abdominal pain, vomiting, tenderness, rebound pain and muscle defense; the CT signs, including transitional zone, dilatation of intestinal loop, high density of intestinal wall; laboratory test results, including white blood cell count, lactate dehydrogenase (LDH) and C-reactive protein (CRP) were analyzed in both groups. Univariate and multivariate regression were used to identify risk factors of strangulated small bowel obstruction. Results:There were significant significances in gender (male vs.female: χ2=4.35, OR=0.67), rebound pain (χ2=170.98, OR=45.12), muscle tension(χ2=113.79, OR=29.32), American Society of Anesthesiologists score (ASA score)≥3 (χ2=12.94, OR=51.58), white blood cell count ( t=6.19, OR=1.14), LDH ( t=2.37, OR=1.00), CRP ( t=2.23, OR=1.01), albumin ( t=2.04, OR=0.97), mesenteric fluid sign (χ2=49.44, OR=5.40), increased bowel wall density (χ2=222.78, OR=62.66), bowel wall thickening sign (χ2=43.81, OR=3.49), ascites (χ2=237.29, OR=43.01), beak sign (χ2=231.50, OR=56.62), mesenteric fat stranding (χ2=242.65, OR=34.90), and stranding sign(χ2=224.79, OR=53.48) between strangulation group and simple group ( P<0.01). The multivariate regression analysis showed that mesenteric fluid sign ( OR=12.94), muscle tension ( OR=7.28), ascites ( OR=6.42), increased bowel wall density ( OR=4.30), bowel wall thickening sign ( OR=1.85), white blood cell count ( OR=1.14) and gender (male vs. female: OR=0.50) were risk factors of strangulated small bowel obstruction. Conclusion:In acute mechanical small bowel obstruction,for female patients presenting mesenteric fluid sign, muscle tension, ascites, increased bowel wall density, bowel wall thickening sign and increased white blood cell count, the strangulated obstruction is likely to occur.

Clinical study of intraperitoneal infusion of bevacizumab combined with albumin paclitaxel and carboplatin in carcinomatous peritoneal adhesion from ovarian cancer / 国际肿瘤学杂志

Objective:To observe the clinical effects of intraperitoneal perfusion of bevacizumab combined with albumin paclitaxel and carboplatin in the treatment of malignant peritoneal adhesion caused by ovarian cancer.Methods:From January 2016 to December 2020, 54 patients treated in our hospital with malignant peritoneal adhesions caused by ovarian cancer were enrolled in this study. They were randomly divided into experimental group ( n=27) and control group ( n=27) according to the random number table method. The treatment regimen of the experimental group was intravenous infusion of albumin paclitaxel plus intraperitoneal infusion of carboplatin and bevacizumab. The treatment regimen of the control group was intra-venous infusion of albumin paclitaxel plus intraperitoneal infusion of carboplatin. The treatment was repeated every 21 days, and the therapeutic effect was evaluated every two cycles. The treatment lasted for six cycles. The efficacy and incidence of adverse reactions were compared between the two groups. Results:The remission rate of incomplete malignant bowel obstruction of the experimental group was higher than that of the control group [85.19% (23/27) vs. 59.26% (16/27)], the total effective rate of the experimental group was higher than that of the control group [74.07% (20/27) vs. 44.44% (12/27)], and there were statistically significant differences ( χ2=4.523, P=0.033; χ2=4.909, P=0.027). After treatment, the levels of vascular endothelial growth factor (VEGF) in ascites of the experimental group and the control group were significantly lower than those before treatment [(80.33±1.41) pg/ml vs. (310.45±3.35) pg/ml, t=449.884, P<0.001; (135.68±1.60) pg/ml vs. (310.46±3.09) pg/ml, t=499.281, P<0.001], and after treatment, the VEGF level in the experimental group decreased more significantly than that in the control group ( t=-134.907, P<0.001). Patients in the experimental group and the control group tolerated the treatment well, and there were no significant differences in the incidences of adverse reactions such as hypertension (11.11% vs. 3.70%, χ2=0.270, P=0.603), neutropenia (14.81% vs. 11.11%, χ2<0.001, P>0.999), peripheral neuropathy (3.70% vs. 0, χ2<0.001, P>0.999), diarrhea (7.41% vs. 3.70%, χ2<0.001, P>0.999), nausea (3.70% vs. 0, χ2<0.001, P>0.999), epistaxis (7.41% vs. 0, χ2=0.519, P=0.471) or albuminuria (3.70% vs. 0, χ2<0.001, P>0.999) between the two groups. Conclusion:Intraperitoneal perfusion of bevacizumab combined with chemotherapy is superior to simple chemotherapy in the treatment of malignant peritoneal adhesion caused by ovarian cancer.

Correlation of intestinal fatty acid binding protein and diamine oxidase with intestinal injury in strangulated bowel obstruction mice / 中华内分泌外科杂志

Objective:To investigate the correlation of intestinal fatty acid binding protein and diamine oxidase with intestinal injury in strangulated bowel obstruction mice.Methods:160 SD rats were divided into 5 groups by random number table: group A ( n=32) : normal control group; group B ( n=32) : sham operation group; group C ( n=32) : simple intestinal obstruction group; The strangulated intestinal obstruction group was divided into group D ( n=32) : acute superior mesenteric artery ischemia group and group E ( n=32) : acute mesenteric arterial and venous ischemia. Except group A, other groups were given operation for modeling. Venous blood and small intestinal segment of group A was collected after anaesthesia, and venous blood and small intestinal segment of other groups were collected after modeling for 4 h. Serum samples were collected from venous blood, and intestinal fluid samples were collected by soaking the small intestinal segments. The intestinal segments were observed and the intestinal injury was evaluated. The levels of intestinal fatty acid binding protein (I-FABP) and activity of diamine oxidase (DAO) in serum and intestinal fluid were detected. Pearson correlation analysis was used to analyze the correlation between intestinal injury and the serum and intestinal fluid levels of I-FABP and activity of DAO, respectively. Results:The intestinal damage scores in group B, C, D and E were higher than that in group A, the intestinal damage scores in groups C, D and E were higher than that in group B, the intestinal damage scores in groups D and E were higher than that in group C, and the intestinal damage score in group E was higher than that in group D ( P<0.05) . The serum I-FABP level and DAO activity in group C, D and E were higher than those in group A and B, and the serum I-FABP level and DAO activity in group D and E were higher than those in group C ( P<0.05) . The level of I-FABP and DAO activity in intestinal fluid in group C, D and E were higher than those in groups A and B, and the level of I-FABP and DAO activity in intestinal fluid in group D and E were higher than those in group C ( P<0.05) . There were positive correlations between intestinal injury and the serum and intestinal fluid levels of I-FABP and activity of DAO, respectively ( r=0.972, P<0.001; r=0.899, P<0.001; r=0.961, P<0.001; r=0.828, P<0.001) . Conclusions:Intestinal injury of strangulated bowel obstruction mice is related to the intestinal ischmia. There are increases of serum and intestinal fluid levels of I-FABP and activity of DAO in strangulated bowel obstruction mice, which are closely related to the degree of intestinal injury.

Therapeutic Efficacy of Conservative Treatment Combined with Water-soluble Contrast Agents for Adhesive Small Bowel Obstruction ：A Meta-analysis / 中国药房

OBJECTIVE： To systematically evaluate th e ther apeutic effects of conservative treatment combined with water-soluble contrast agents for adhesive small bowel obstruction ，and to provide evidence-based reference for clinical medication. METHODS：Retrieved from Cochrane library ，PubMed，Embase，Wanfang database and CNKI during the inception to Sept. 2020，RCTs about conservative treatment combined with water-soluble contrast agents in the therapeutic efficacy for adhesive small bowel obstruction were collected. After literature screening and data extraction ，the quality of included literatures were evaluated with Cochrane system evaluator manual 5.1.0 and Jadad scale. Meta-analysis was conducted by using Rev Man 5.3 and Stata 16 software. RESULTS ：A total of 15 RCTs were included ，with 1 429 patients in total. Results of Meta-analysis showed that the use of water-soluble contrast agents significantly reduced the surgical needs of patients with adhesive small bowel obstruction [OR ＝ 0.64，95％CI（0.50，0.81），P＜0.001]；reduced the remission time of non-surgical patients [MD ＝－23.37， 95％CI（－32.17， －14.57），P＜0.001]，hospital stay days of non-surgical patients [MD ＝－2.21，95％CI（－2.52，－1.90），P＜0.001] and hospital stay days of all patients [MD ＝－2.43，95％CI（－3.93，－0.92），P＝0.002]，and would not increase the incidence of complications [OR ＝1.15，95％CI（0.63，2.10），P＝0.65]，but could not reduce mortality [OR ＝1.26，95％CI（0.94，3.24），P＝ 0.63] or the probability of bowel resection [OR ＝0.93，95％CI（0.57，1.52），P＝0.78]. CONCLUSIONS ：The combined use of water-soluble contrast agents for patients with adhesive small bowel obstruction is safe and effective ，can reduce the patient ’s surgical requirements ，and is beneficial to reduce the length of hospital stay and time for symptom relief.

Small Bowel Obstruction Due to Rice Cake Consumption / 日本プライマリ・ケア連合学会誌

Introduction: There is an increasing number of reports demonstrating that dietary small bowel obstruction caused by rice cake consumption can be treated conservatively. However, the course of conservative treatment and the characteristics of the cases that require surgery remain unclear. The purpose of this study was to clarify the clinical features of small bowel obstruction caused by rice cake consumption and the characteristics of cases that require surgery.Methods: We retrospectively assessed all cases of intestinal obstruction caused by rice cake consumption treated at a single institution over a period of 7 years. We also assessed similar previously reported cases.Results: We assessed nine cases in our study and reviewed 67 previously reported cases. Conservative treatment was employed in 56 cases (73.7%). Dietary small bowel obstruction caused by rice cake consumption occurred 1.7 ± 0.3 days after intake. The computed tomography (CT) value of rice cake in the intestine was 160.0 ± 8.9 Hounsfield Units. Pieces of rice cake (length ≥ 4 cm) were observed in five of six cases in which rice cake consumption caused intestinal perforation.Conclusion: In most cases, patients with dietary small bowel obstruction caused by rice cake consumption will recover after conservative treatment. However, there is a high risk of intestinal perforation if intestinal CT reveals the length of rice cake pieces to be 4 cm or longer.

Enteritis por radiación: reporte de un caso y revisión de la literatura / Radiation enteritis. Case report and literature review

Resumen La enteritis por radiación es una patología causada por la radiación que se suministra durante el manejo de neoplasias radiosensibles. Esta enfermedad puede clasificarse en enteritis aguda o crónica, en las cuales es posible que se desarrollen síntomas por malabsorción u obstrucción intestinal, que alteran la calidad de vida de los pacientes. Presentamos el reporte de caso de un paciente masculino de 67 años, con antecedente de adenocarcinoma difuso con células en anillo de sello infiltrante y compromiso de todo el espesor de la pared gástrica, quien había recibido un manejo quirúrgico mediante gastrectomía total, asociado a quimio-radioterapia. El individuo consultó por síntomas de obstrucción intestinal. En principio, se consideró la existencia de una recaída tumoral. Sin embargo, se corroboró que los síntomas estaban relacionados con el compromiso causado por la radiación.

Abstract Radiation enteritis is a pathology caused by radiation therapy, used to treat radiosensitive tumors. Acute or chronic enteritis may be suspected in the presence of symptoms such as malabsorption or intestinal obstruction, which alter the patients quality of life. The following is the case report of a 67-year-old male patient, who consulted for symptoms of intestinal obstruction, with a history of diffuse type adenocarcinoma with infiltrating signet ring cells involving the entire thickness of the gastric wall. The patient underwent a total gastrectomy associated with chemoradiotherapy.

Obstrucción intestinal secundaria a enteritis por radiación: reporte de un caso / Bowel obstruction secondary to radiation enteritis: A case report

La enteritis por radiación o enteritis actínica es una complicación secundaria al uso de radioterapia para tratamiento de tumores pélvicos, que puede afectar con mayor frecuencia al intestino delgado (principalmente íleon) y al colon. La cirugía en pacientes con enteritis por radiación crónica debe reservarse ante la presencia de complicaciones, ya que está relacionada con una alta morbilidad y estancia hospitalaria prolongadas, así como posibilidad de re operación. Exponemos el caso de una paciente con oclusión intestinal secundaria a enteritis por radiación que desarrolló años después de la conclusión de su tratamiento por cáncer de cuello uterino, con el objetivo de que esta enfermedad sea sospechada en pacientes con antecedentes de radiación.

Radiation enteritis or actinic enteritis is a complication secondary to the use of radiotherapy to treat pelvic tumors, which can more frequently affect the small intestine (mainly ileum) and the colon. Surgery in patients with chronic radiation enteritis should be reserved in the presence of complications, since it is related to high morbidity and prolonged hospital stay, as well as the possibility of reoperation. We present the case of a patient with intestinal occlusion secondary to radiation enteritis who developed years after the conclusion of her treatment due to cervical cancer, with the objective that this disease has to be suspected in patients with history of radiation.

Closed loop small bowel obstruction due to mid urethral sling mesh

Closed loop small bowel obstruction is a surgical emergency, which when left untreated leads to vascular compromise resulting in intestinal ischemia, necrosis and perforation. We report the case of a 61 years old female with past surgical history of hysterectomy and a mid-urethral sling, who presented to the emergency department for abdominal pain and obstipation. She was found on imaging to have a closed loop small bowel obstruction. An exploratory laparotomy revealed an adhesive band encompassing the distal terminal ileum, visceral peritoneum and the Mid‐urethral slings mesh. This is a rare complication that, to our knowledge, has not been reported in the surgical literature. This paper will discuss the clinical presentation, diagnostic studies, therapeutic intervention and outcome of this unique case.

Gallstone ileus, the forgotten one: a rare cause of intestinal perforation and a case report

Gallstone ileum represents an unusual cause of intestinal obstruction as a result of the presence of stones that cause mechanical obstruction. It has an incidence of less than 4%. Reaching mortality up to 25% of cases. It is a difficult suspicion, with characteristic signs that guide its presence such as pneumobilia, occlusion, and the presence of stone in radiological studies. Management should include surgical extraction as well as revision of the entire intestine with a suitable subsequent repair. Authors present the case of a 70-year-old patient with the presence of surgically resolved biliary ileum.

Rare case of paracaecal hernia with intussusception presenting as small bowel obstruction: case report

Primary internal hernias are very rare in adults. They are an unusual cause of small intestinal obstruction and lead to high morbidity and mortality if left untreated. Clinical presentation of internal hernia is highly nonspecific. Imaging has limited role in diagnosing the cause of acute intestinal obstruction. Internal hernias are usually detected at laparotomy. We report a case of a 61-year-old male who presented with acute intestinal obstruction which was attributed later to a very rare type of internal hernia on exploratory laparotomy. A loop of ileum was found to enter the retroperitoneum through a hernia gate which was located lateral to the caecum and ileo ileal intussusception was noted proximal to the herniated loop. The segment of intestine was resected and anastamosed then hernial defect was closed. Paracaecal hernias are the rare type of hernias in internal hernia. In our case, intussusception was noted proximal to the herniated ileal loop which is a very rare presentation. Intussusception was reported previously with paraduodenal type. One should always keep in mind while conducting emergency laparotomy, internal hernias can be a cause for intestinal obstruction.

Phytobezoar induced small bowel obstruction: an uncommon cause of intestinal occlusion

A case of a 42-year-old female patient with a two-days diffuse colicky abdominal pain, nausea and three episodes of vomiting is presented. Furthermore, patient complained for inability to eat for almost a week. In addition, patient had a history of subtotal gastrectomy Billroth II-type, due to gastric ulcer six years ago. There were no other known co-morbidities. Except for a distended, somewhat painful abdomen and sluggish bowel sounds, the rest clinical examination was unremarkable. Plain abdominal X-ray and ultrasound findings agreed with the clinical suspicion of sub-acute small bowel obstruction probably due to post-operative adhesions. A conservative management was decided. However, the patient after an initial clinical improvement, had a relapse of symptoms with the first feeding attempt. A followed computed tomography of the abdomen revealed a well define, oval, mass-like containing mostly air bubbles lesion, occupying for approximately six centimeters long the jejunum lumen. The diagnosis of jejunal phytobezoar was set. In accordance of computed tomography diagnosis were the intra-operative findings and the post-operative histopathology.

Assessment of Small Bowel Obstruction in Patients Following Appendicitis: An Institutional Based Study

Background: Small bowel obstruction (SBO) is a pathologicalcondition which occurs when the intestinal contents areprevented from moving along the length of the intestine. Thepresent study was conducted to assess the cases of smallbowel obstruction following appendectomy.Materials & Methods: The present study was conducted on42 cases of appendicitis of both genders. In all patients,laparoscopic appendectomy was planned. Patients wererecalled to note any kind of complication arising from theprocedure.Results: Out of 42 patients, males were 26 and females were16. Age group 20-30 years had 5 males and 3 females, 30-40years had 9 males and 5 females and 40-50 years had 12males and 8 females. The difference was significant (P< 0.05).Macroscopic feature of appendix during procedure wasphlegmonous in 12 and gangrenous in 30 cases. Thedifference was significant (P< 0.05).Conclusion: Small bowel obstruction is a complication whichmay be seen in few cases of appendectomy.

Clinical evaluation of MDCT multi-postprocessing techniques for diagnosing small bowel obstruction / 解放军医学杂志

Objective To evaluate the clinical effects of multi-detector computed tomography (MDCT) multi-postprocessing techniques in the evaluation of small bowel obstruction (SBO). Methods Clinical and MDCT imaging data of 90 patients with SBO were collected. Three radiologists respectively applied two protocols (protocol 1 consisted of conventional axial and coronal reformations and protocol 2 involved integration of multiple post-processing techniques) to image post-processing and interpretation of patients' MDCT volume data, and completed condition evaluation reports. Two protocols were compared regarding relevant diagnostic self-confidence, clinical satisfaction, clinical treatment decisions, and radiological adverse events. Results In the same protocol, the diagnostic self-confidence showed no significant difference between three radiologists for any evaluation parameter (P>0.05), but the diagnostic self-confidence of three radiologists was significantly higher in the protocol 2 than in the protocol 1 (P<0.01). The clinical satisfaction was also significantly higher in the protocol 2 than in the protocol 1 for all the individual and compositive illness assessment reports (P<0.01). After protocol 2 was applied clinically, it changed the previous treatment decisions based on protocol 1 in 11 patients (12.22%). About radiological adverse events, regardless of minor, major, or the sum of them, protocol 1 was significantly higher than protocol 2 (P<0.05). Conclusion Integration of multi-postprocessing techniques can improve diagnostic self-confidence and clinical satisfaction of MDCT for assessing SBO and effectively reduce radiological adverse events.
