Abstract
Background: Patients with prior abdominal surgeries are at higher risk for intra-abdominal adhesive tissue formation and subsequently higher risk for small bowel obstruction (SBO).Purpose: In this study, we investigated whether surgical intervention for SBO was more likely following specific types of abdominal surgeries.Research Design: With retrospective chart review, we pooled data from 799 patients, ages 18 to 89, admitted with SBO between 2012 and 2019. Patients were evaluated based on whether they underwent surgery or were managed conservatively. They were further compared with regard to past surgical history by way of type of abdominal surgery (or surgeries) undergone prior to admission.Results: Of the 799 patients admitted for SBO, 206 underwent surgical intervention while 593 were managed nonoperatively. There was no significant difference in number of prior surgeries (2.07 ± 1.56 vs 2.36 ± 2.11, P = .07) or in number of comorbidities (2.39 ± 1.97 vs 2.65 ± 1.93, P = .09) for surgical vs non-surgical intervention. Additionally, of the operations evaluated, no specific type of abdominal surgery predicted need for surgical intervention in the setting of SBO. However, for both surgical and non-surgical intervention following SBO, pelvic surgery was the most common type of prior abdominal surgery (45% vs 43%). There are significantly more female pelvic surgeries in both the operative (91.4% vs 8.6%, P < .0001) and nonoperative groups (89.9% vs 10.2%, P < .0001).Conclusion: Ultimately, no specific type of prior operation predicted the need for surgical intervention in the setting of SBO.

Abstract
Small bowel obstruction (SBO) impacts the health care system and patient quality of life. Previously, we evaluated differences between medical and surgical admissions in the management of SBO. This study investigates indications for readmission based on original admission to medical (MS) or surgical services (SS). A retrospective chart review was performed for 799 patients aged 18 to 89 admitted between 2012 and 2019 with a diagnosis of SBO. Patient characteristics examined included length of stay (LOS), prior abdominal operations, prior SBO, use of small bowel follow through imaging, operative intervention, mortality, and 30-day readmission. There was no difference in readmission rates in patients originally admitted to MS or SS (13.2% vs 12.7%, P = .86). Patients admitted to SS were more likely to be readmitted for recurrent SBO (39% vs 8.6%, P = .006). Patients admitted to MS were more likely to be readmitted for other reasons (73.9% v. 40.2%, P = .004). In the MS cohort, 30.4% (7 patients) had surgery during their initial admission for SBO, and none of those patients were readmitted for recurrent SBO (rSBO). In the SS cohort, 23% had surgery during their initial admission and 31.6% were readmitted for rSBO (P = .002). Patients admitted to SS were more likely to be readmitted for rSBO and to require surgery. Patients admitted to MS were more likely to be readmitted for other reasons. None of the MS patients who had surgery were readmitted for SBO. 31.6% of SS patients who had surgery were readmitted for SBO.

Assessing the Modified Frailty Index and Post-Operative Outcomes in Adhesive Small Bowel Obstruction: A Retrospective Cohort Study. J Surg Res 2024; 297:71-82. [PMID: 38447338 DOI: 10.1016/j.jss.2023.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 09/18/2023] [Accepted: 12/16/2023] [Indexed: 03/08/2024]
Abstract
INTRODUCTION Studies identifying predictors of postoperative outcomes in adhesive small bowel obstruction are limited. This study investigates the efficacy of the modified frailty index (mFI)to predict postoperative morbidity and mortality among patients undergoing surgery for adhesive small bowel obstruction. METHODS A multicentre retrospective cohort study including patients undergoing surgery for adhesive small bowel obstruction after failed trial of nonoperative management between January 2015 and December 2020 was performed. Impact of frailty status using the mFI, stratified as frail (≥0.27) and robust (<0.27), on postoperative morbidity, mortality, length of stay, and discharge destination was evaluated using multiple logistic regression. RESULTS Ninety-two robust patients (mean age 62.4 y, 68% female) and 41 frail patients (mean age 81.7 y, 63% female) were included. On simple stratification, frail patients had significantly increased 30-d morbidity (overall morbidity 80% versus 49%) and need for higher level of care on discharge (41% versus 9%). However, on multiple regression, functional dependence but not the mFI, was independently associated with worse 30-d overall morbidity (odds ratio [OR] 3.97, confidence interval [CI] 1.29-12.19) and lower likelihood of returning to preoperative disposition (OR 0.21, CI 0.05-0.91). The delay in operation beyond 5 d was independently associated with worse 30-d outcomes including overall morbidity and mortality (OR 7.54, CI 2.13-26.73) and decreased return to preoperative disposition (OR 0.14, CI 0.04-0.56). CONCLUSIONS The mFI, although promising, was not independently predictive of outcomes following surgery for adhesive small bowel obstruction. Further adequately powered studies are required.

Abstract
ABSTRACT Obesity remains a global health challenge linked to several comorbidities, such as obstructive sleep apnea, hypertension, hyperlipidemia, and diabetes. The prevalence of bariatric surgeries being performed is steadily increasing because it is a highly effective surgical tool used to achieve significant permanent weight loss. However, with all weight loss surgeries, several complications may not present for months to years after the initial procedure. In particular, the anatomical changes that occur after the Roux-en-Y gastric bypass (RNYGB) make the risk of internal hernias high. This particular complication is rare but lethal if unrecognized and not treated promptly. This clinical case study aims to provide readers with an overview of diagnosing and recognizing an internal hernia in the setting of previous laparoscopic RNYGB surgical history. Because of the sheer increase in the volume of patients undergoing bariatric surgery worldwide, health care providers must be well educated on the insidious presentations of this late complication and be prepared to act quickly to diagnose and treat these acute abdomen scenarios.

Abstract
BACKGROUND There are limited data identifying predictors of postoperative outcomes in adhesive small bowel obstruction (ASBO). This study used the National Inpatient Sample (NIS) to assess the efficacy of the modified frailty index (mFI) to predict postoperative morbidity among patients undergoing an operation for ASBO. METHODS A retrospective analysis of the NIS between September 1, 2015, and December 31, 2019, was performed to identify adult patients who underwent nonelective operative intervention for ASBO. The mFI was used to stratify patients as either frail (mFI value ≥ 0.27) or robust (mFI value < 0.27). The primary outcomes were overall in-hospital postoperative morbidity and mortality. The secondary outcomes were system-specific morbidity, length of stay (LOS), total in-hospital healthcare cost, and discharge disposition. Univariable and multivariable regressions were used. RESULTS Overall, 23251 robust patients and 6122 frail patients were included. Adjusted analyses demonstrated that frail patients had increased in-hospital mortality (adjusted odds ratio [aOR], 2.16; 95% CI, 1.80-2.60), postoperative morbidity (aOR, 1.63; 95% CI, 1.52-1.74), postoperative LOS (adjusted mean difference [aMD], 0.97 days; 95% CI, 0.73-1.21), and total in-hospital healthcare costs (aMD, $18,921; 95% CI, $14,608-$23,235) and were less likely to be discharged home (aOR, 0.59; 95% CI, 0.55-0.63). The findings were unchanged on subgroup analysis of patients undergoing open operation and those older than 65 years of age. CONCLUSION The mFI may predict postoperative outcomes for ASBO. Stratifying patients based on frailty may assist clinicians and patients in making informed decisions, setting realistic expectations, and proactively planning postoperative disposition.

Abstract
Acquiring large amounts of hyperspectral data of small intestinal tissue with real labels in the clinic is difficult, and the data shows inter-patient variability. Building an automatic identification model using a small dataset presents a crucial challenge in obtaining a strong generalization of the model. This study aimed to explore the performance of hyperspectral imaging and transfer learning techniques in the automatic identification of normal and ischemic necrotic sites in small intestinal tissue. Hyperspectral data of small intestinal tissues were collected from eight white rabbit samples. The transfer component analysis (TCA) method was performed to transfer learning on hyperspectral data between different samples and the variability of data distribution between samples was reduced. The results showed that the TCA transfer learning method improved the accuracy of the classification model with less training data. This study provided a reliable method for single-sample modelling to detect necrotic sites in small intestinal tissue .

Adhesive small-bowel obstruction as a challenging complication of familial Mediterranean fever: A case-based review. Int J Rheum Dis 2024; 27:e14867.

Abstract
Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disorder, characterized by recurrent and self-limiting episodes of fever and serosal inflammation. Recurrent serositis may rarely lead to the formation of adhesions in the peritoneum, which may result in mechanical bowel obstruction. The symptoms, such as abdominal pain and vomiting, may mimic typical FMF attacks, resulting in misdiagnosis and severe morbidity, including strangulation and intestinal necrosis. Physicians are generally aware of other complications associated with FMF but reports on peritoneal adhesions and intestinal obstruction in English-language literature are inadequate to increase clinicians' awareness. Therefore, it is crucial to meticulously evaluate FMF patients presenting with abdominal pain and ileus because these symptoms could be due to adhesive small-bowel obstruction (ASBO). Furthermore, patients presenting with ASBO without a history of abdominal surgery should also be thoroughly evaluated, especially as it could be an initial presentation for an autoinflammatory disease. Herein, we present a pediatric case of FMF with the M694V homozygous mutation, complicated by ASBO while under colchicine treatment. Additionally, we provide a comprehensive review of the available literature on ASBO in FMF.

Abstract
Intussusception occurs when a part of the intestine enters another segment of the intestine causing bowel obstruction. It is common in children but not in adults with only <5% of prevalence of all intussusceptions. Most of the cases have an underlying neoplastic pathology. However, we found a case where an adult patient with 2 weeks of ileus obstruction is caused by intussusception with multiple intestinal adhesions. A 59-year-old man complained of being unable to defecate, or vomit and had a tender abdomen for 2 weeks. Contrast abdominal CT showed a dilated and thickened intestinal wall, with ileo-ileal intussusception in the distal terminal ileum, indicating a diagnosis of ileus obstruction due to intussusception. During laparotomy, intussusception was found but released spontaneously followed by ancillary findings were multiple adhesions in the ileum that caused the intussusception and obstruction. In conclusion, transient intussusception in adults with multiple adhesions has never been reported before, and a CT scan is an important clinical tool to diagnose and identify the cause of this condition. Recognizing the imaging abnormalities earlier is important to prevent further complications.

Abstract
In this case report, we present a rare occurrence of a narrow-ridged finless porpoise (Neophocaena asiaeorientalis sunameri), discovered on the coast of Jeju Island, Republic of Korea, that was afflicted with adhesive bowel obstruction (ABO), a life-threatening condition that has scarcely been reported in cetaceans. Diagnosis of ABO was confirmed via radiological and clinical assessments. Post-mortem computed tomography and necropsy revealed ABO between two loops of the jejunum at the L8 level. The mesenteric tissue covering the intestinal lesion was severely thickened with increased tension. Both bowel loops were fixed to the mesentery and acutely angulated, leading to asymmetrical thickening of the cross-sectional bowel walls. The intestinal lumen was stenosed because of pressure from the firm mesenteric band, and no fecal matter was observed in the lumen of the posterior bowel or rectum. Calcified nodules were detected, and histological analysis suggested parasitic or suspected post-parasitic infections. The primary cause of the intestinal lesions is presumed to be a reaction related to parasitic infection. However, further investigations would establish a definitive link between parasitic infections and ABO in this species. This case highlights the importance of studying rare medical conditions in wildlife, providing valuable insights into marine mammal health.

Abstract
Key Clinical Message Peritoneal encapsulation is most of the time asymptomatic and is found incidentally, but when symptomatic it usually presents with bowel obstruction. CT scan is a gold standard for the diagnosis of bowel encapsulation. Abstract Congenital peritoneal encapsulation (CPE), abdominal cocoon syndrome (ACS), and sclerosing encapsulating peritonitis (SEP) are syndromes in which the small bowel is encapsulated. Small bowel encapsulation is usually asymptomatic and rarely presents with small bowel obstruction. In this article, we report a 65-year-old man who presented to our hospital with signs and symptoms of small bowel obstruction. He underwent an urgent operation, and small bowel encapsulation was diagnosed. One year after the surgery, all symptoms improved.

Abstract
BACKGROUND Decompression of the intestine with a long tube or nasogastric tube is the first-choice treatment for adhesive small bowel obstruction (ASBO). Scheduling surgery while weighing the risks of surgery against conservative care is a crucial factor in clinical decision-making. Whenever feasible, unnecessary surgeries should be avoided, and it is essential to provide clinical markers for this. This study aimed to obtain evidence regarding the optimal timing of ASBO and when conservative treatment options are not successful. METHODS The data of patients diagnosed with ASBO and receiving long tube insertion for more than 7 days were reviewed. We investigated transit ileal drainage volume and recurrence. The primary outcomes were the change in the drainage volume from the long tube over time and the percentage of patients who required surgery. We evaluated some cutoff values to determine the indication for surgery based on the insertion duration and volume of long tube drainage. RESULTS Ninety-nine patients were enrolled in this study. Fifty-one patients showed improvement with conservative treatment, whereas 48 ultimately required surgery. When a daily drainage volume of ≥500 mL was considered an indication for surgery, 13-37 cases (25%-72%) would be judged unnecessary within 6 days of long tube insertion, while 5 cases (9.8%) would be judged unnecessary on day 7. DISCUSSION Unnecessary surgical interventions for ASBO might be avoided by assessing the drainage volume on day 7 after inserting a long tube.

Abstract
Introduction Adhesive small-bowel obstruction (ASBO) is a common condition requiring emergency room admission, and predicting the need for intensive care unit (ICU) hospitalisation is crucial for optimal patient management. This study aimed to investigate the predictive value of various scores and indices in determining ICU requirements in patients with ASBO. Patients and Methods Seventy patients diagnosed with ASBO and managed nonoperatively were included in the study. Data on patient demographics, laboratory values, imaging findings, previous hospitalisations and comorbidities were collected. The Sequential Organ Failure Assessment (SOFA) score, Charlson Comorbidity Index (CCI) score and C-reactive protein (CRP)/albumin ratio were calculated. Patients were categorised into ICU and non-ICU groups for analysis. Results The ICU group comprised patients with higher number of previous ASBO hospitalisations and longer hospitalisation days. Serum albumin levels were significantly lower and the maximum small-bowel horizontal diameter was significantly higher in the ICU group. The SOFA score and CCI score were significantly higher in the ICU group. The CRP/albumin ratio showed a trend towards significance. Conclusion The number of days since the last stool discharge, SOFA score and CCI score demonstrated significant associations with ICU requirements in ASBO patients. These findings highlight the importance of assessing organ dysfunction, comorbidities and gastrointestinal function during patient triage. Our study provides valuable insights into predicting ICU need in ASBO patients, aiding in resource allocation and patient management.

Abstract
INTRODUCTION AND IMPORTANCE Small bowel obstruction (SBO) is common in daily practice in emergency department. It has many causes such as adhesions or hernias. Other causes are obstruction by a bulky mass such as tumors of the intestine. CASE PRESENTATION We present a rare case of small bowel obstruction in a 48 years old male patient with Crohn's disease. Laparotomy showed a mass that caused the obstruction. Pathology report demonstrated that it is leiomyoma. This finding may cause a delay in making the diagnosis of SBO. CLINICAL DISCUSSION Small bowel obstruction is considered an emergency case in the emergency. It needs special attention and advanced medical practice to reach the diagnosis. Rare cases may lead to delay the diagnosis because they present unusually. CONCLUSION Physicians should consider leiomyoma as a cause of SBO with patients without clear cause of SBO.

Abstract
OBJECTIVES To investigate the diagnostic value of unenhanced CT in mechanical small bowel obstruction (SBO) with small bowel necrosis, and to establish a predictive model. METHODS From 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. RESULTS A 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. CONCLUSION Multiple 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.

Abstract
Intestinal adhesions are fibrotic bands of scar tissue that develop intra-abdominally due to serosal or peritoneal irritation caused during surgery or by severe infections. It may also occur congenitally. It can lead to serious complications such as small bowel obstruction, which is then termed adhesive small bowel obstruction. In this scenario, it can constrict the bowel wall and cause ischemia and necrosis of the affected intestinal segment. Computed tomography imaging may show characteristic signs, such as the "whirl sign" or "fat-bridging sign." Diagnostic laparoscopy or laparotomy can confirm the diagnosis and presence of adhesions. Management of this condition is either conservative or surgical, the latter of which is necessary in the case of intestinal strangulation. While the literature supports the laparoscopic method of adhesiolysis, practically, it may present technical difficulties. Surgeons should employ their clinical judgment in cases where an open procedure may be more beneficial. We present a case of this very occurrence and discuss the risk factors, pathogenesis, diagnostic evaluation, and, finally, the approaches to surgical management of this condition.

Abstract
UNLABELLED Adhesion is a leading cause of small bowel obstruction. Adhesive small bowel obstruction has significant challenges in diagnosis, treatment and prevention with considerable impact on morbidity and socioeconomic burden. Small bowel obstruction caused by adhesion or any other aetiology is clinically indistinguishable due to similar clinical presentation. Computed Tomography scans and water-soluble contrast studies are more specific in diagnosis and possess value in predicting the need for surgery. Surgical management is indicated only in complicated cases or failed conservative treatments with the majority resolving with non-operative management. However, there is no clear-cut consensus about the timing of operative intervention. Meticulous surgical practice is the keystone in preventing adhesion formation despite the availability of numerous pharmacological and surgical strategies. This review aims to update the current knowledge of the pathophysiology of adhesion formation, treatment options and various prevention modalities of adhesive small bowel obstruction.

Abstract
PURPOSE Definitive radiation therapy (RT) for locally advanced node-positive cervical cancer confers significant toxicity to pelvic organs including the small bowel. Gross nodal disease exhibits significant shrinkage during RT, and yet conventional RT does not account for this change. We evaluated the reduction in absorbed bowel dose using various adaptive RT schedules. METHODS AND MATERIALS We obtained 130 evaluable scans (computed tomography simulation and 25 cone beam computed tomography scans per patient) of 5 patients who had received definitive external beam RT for lymph node positive cervical cancer daily over 5 weeks. Using a single universal volumetric modulated arc therapy plan with predefined optimization priorities, we created adapted RT plans in 4 schedules: Daily, Weekly, Twice, and NoAdapt (mimicking conventional nonadapted RT). The in silico (computer modeled) patients were treated to 45 Gy to primary cervical disease with a simultaneous integrated boost to 55 Gy to involved lymph nodes. We evaluated dose metrics including D2cc, D15cc, and V45 to determine the impact of adapted RT schedules on bowel sparing. Statistical tests included the Student t test, analysis of variance, and the Spearman rank correlation. RESULTS The quantity of reduced bowel dose was significantly associated with the chosen planning schedule in all evaluated metrics and was proportional to the frequency of adaptive RT with significant moderate-to-strong monotonicity. Both D2cc and D15cc were reduced an average of 2.7 Gy using daily replanning compared with a nonadapted approach. A minimally adapted strategy of only 2 replans also confers a significant dosimetric benefit over a nonadapted approach. Reduced standard deviations of D2cc and V45 bowel doses over the treatment courses were significantly associated with the choice of planning schedule with strong monotonicity. CONCLUSIONS All adaptive RT schedules evaluated confer significant dosimetric advantages in bowel sparing over a conventional nonadapted technique, with greater sparing seen with more frequent replanning schedules. These findings warrant future trials of adaptive RT for pelvic malignancies.

Abstract
Postoperative abdominal adhesions are a common problem after surgery and can produce serious complications. Current antiadhesive strategies focus mostly on physical barriers and are unsatisfactory and inefficient. In this study, we designed and synthesized advanced injectable cream-like hydrogels with multiple functionalities, including rapid gelation, self-healing, antioxidation, anti-inflammation, and anti-cell adhesion. The multifunctional hydrogels were facilely formed by the conjugation reaction of epigallocatechin-3-gallate (EGCG) and hyaluronic acid (HA)-based microgels and poly(vinyl alcohol) (PVA) based on the dynamic boronic ester bond. The physicochemical properties of the hydrogels including antioxidative and anti-inflammatory activities were systematically characterized. A mouse cecum-abdominal wall adhesion model was implemented to investigate the efficacy of our microgel-based hydrogels in preventing postoperative abdominal adhesions. The hydrogels, with a high molecular weight HA, significantly decreased the inflammation, oxidative stress, and fibrosis and reduced the abdominal adhesion formation, compared to the commercial Seprafilm group or Injury-only group. Label-free quantitative proteomics analysis demonstrated that S100A8 and S100A9 expressions were associated with adhesion formation; the microgel-containing hydrogels inhibited these expressions. The microgel-containing hydrogels with multifunctionality decreased the formation of postoperative intra-abdominal adhesions in a murine model, demonstrating promise for clinical applications.

Abstract
Postoperative abdominal adhesion is one of the most common complications after abdominal surgery. A single drug or physical barrier treatment does not achieve the ideal anti-adhesion effect. We developed a thermosensitive hydrogel (PPH hydrogel) consisting of poloxamer 407 (P407), poloxamer (P188), and hydroxypropyl methylcellulose (HPMC) co-blended. An injectable thermosensitive TA/MMC-PPH hydrogel was obtained by loading tannic acid (TA) with an anti-inflammatory effect and mitomycin C (MMC), which inhibits fibroblast migration or proliferation. The optimal prescriptions of PPH hydrogels with a suitable gelling time (63 s) at 37 °C was 20% (w/v) P407, 18% (w/v) P188, and 0.5% (w/v) HPMC. The scanning electron microscopy (SEM) revealed that the PPH hydrogel had a three-dimensional mesh structure, which was favorable for drug encapsulation. The PPH hydrogel had a suitable gelation temperature of 33 °C, a high gel strength, and complicated viscosity at 37 °C, according to the rheological analysis. In vitro release studies have shown that the PPH hydrogel could delay the release of TA and MMC and conform to the first-order release rate. Anti-adhesion tests performed on rats in vivo revealed that TA/MMC-PPH hydrogel significantly reduced the risk of postoperative adhesion. In conclusion, the TA/MMC-PPH hydrogel prepared in this study showed an excellent performance in both controlled drug release and anti-adhesive effects. It can be used as a protocol to prevent or reduce postoperative abdominal adhesion.

Abstract
OBJECTIVE The aim: The study aimed to evaluate some criteria for preoperative diagnosis of strangulation and significant indicators of the prognosis of short-term outcomes in patients with small bowel obstruction. PATIENTS AND METHODS Materials and methods: The results of the treatment of 123 patients aged 18-70 years with SBO were evaluated. RESULTS Results: All of these patients underwent emergency surgery, and 22 patients (17.9%) have died. It has been shown that four lab parameters (blood leukocytes, lactate, intestinal fatty acid-binding protein, and C-reactive protein levels) and one instrumental (involving the mesentery of the small intestine, free fluid in the abdomen during CT) with 80% probability or more were associated with the strangulation type of SBO (Λ=0.276, p = 0.000). Three lab indicators (WBC count, serum lactate, and intestinal fatty acid-binding protein levels) and two clinical parameters (abdominal perfusion pressure level and the presence of abdominal sepsis) were associated with early mortality after surgery (Λ=0.626, p = 0.000) with the same probability. Immediate results of the treatment in these patients depended on the development of intra-abdominal complications after surgery (P = 0.024) and the need for early reoperation (P = 0.006) as well as the development of cardiovascular dysfunction (P = 0.000) and respiratory dysfunction (P = 0.000). CONCLUSION Conclusions: There were confirmed parameters that were significantly associated with strangulation before surgery and short-term in-hospital mortality with an 80% probability or more. This made it possible to develop new mathematical models for the diagnosis of strangulated bowel obstruction and early postoperative mortality with an accuracy of 84.5% and 84.2%, respectively.

Abstract
Introducción. La obstrucción intestinal por bridas representa una causa común de consulta a los servicios de urgencias, pero hay poca claridad sobre qué pacientes tienen mayor riesgo de desarrollar complicaciones. El objetivo de este estudio fue diseñar y validar una escala de predicción de riesgo de desenlaces adversos en pacientes con obstrucción intestinal por bridas.
Métodos. Estudio de cohorte retrospectivo realizado a partir de la base de datos MIMIC-IV. Se incluyeron pacientes adultos admitidos al servicio de urgencias entre 2008 y 2019, con diagnóstico de obstrucción intestinal por bridas. El desenlace principal fue el compuesto de resección intestinal, ingreso a unidad de cuidados intensivos y mortalidad por cualquier causa. Se diseñó una escala de predicción de riesgo asignando un puntaje a cada variable.
Resultados. Se incluyeron 513 pacientes, 63,7 % hombres. El desenlace compuesto se presentó en el 25,7 % de los casos. La edad, historia de insuficiencia cardiaca y enfermedad arterial periférica, nivel de hemoglobina, recuento de leucocitos e INR constituyeron el mejor modelo de predicción de estos desenlaces (AUC 0,75). A partir de este modelo, se creó la escala simplificada HALVIC, clasificando el riesgo del desenlace compuesto en bajo (0-2 puntos), medio (3-4 puntos) y alto (5-7 puntos).
Conclusión. La escala HALVIC es una herramienta de predicción simple y fácilmente aplicable. Puede identificar de manera precisa los pacientes con obstrucción intestinal por bridas con alto riesgo de complicaciones, permitiendo el ajuste individualizado de las estrategias de manejo para mejorar los desenlaces.

Abstract
Introducción. La obstrucción intestinal es una patología de alta prevalencia. Su abordaje diagnóstico y terapéutico ha evolucionado acorde con el avance del conocimiento e implementación de la tecnología. El impacto de sus complicaciones obliga a redoblar esfuerzos en pro de lograr una mayor efectividad. Se hizo una aproximación reflexiva al problema, mediante una identificación de los puntos controversiales de interés para el cirujano general.
Métodos. Se realizó una búsqueda sistemática de la literatura en varias bases de datos, utilizando dos ecuaciones de búsqueda que emplearon términos seleccionados a partir de los tesauros “Medical Subject Heading” (MeSH) y “Descriptores en Ciencias de la Salud” (DeCS).
Resultados. Se recolectaron 43 artículos y a partir de ellos se construyó el texto de revisión. La identificación pronta de los posibles candidatos a cirugía, mediante un esquema diagnóstico y terapéutico, se constituye en una prioridad en el manejo de estos pacientes. De igual manera, se efectúan consideraciones en la toma de decisiones con respecto a la vía quirúrgica, así como recomendaciones técnicas operatorias producto de la experiencia y lo reportado en la literatura. Existen factores propios del cirujano, del contexto y del paciente, que inciden en la resolución del problema.
Conclusión. La obstrucción intestinal y sus implicaciones clínicas obligan a una reevaluación constante de su estado del arte y avances en el manejo, tendiente a una búsqueda de oportunidades para impactar favorablemente en su curso clínico. Hay estrategias por implementar, inclusive el manejo laparoscópico en casos seleccionados.

Abstract
OBJECTIVE To explore the guiding value of radiography after transnasal ileus intubation for the treatment of small bowel obstruction and the selection of surgical timing. METHODS This retrospective study analyzed the clinical data of 133 patients with small bowel obstruction who were admitted to Gongli Hospital from January 2013 to December 2020. The patients were included in a nasogastric intubation group (n=65) or a transnasal ileus intubation + radiography group (n=68), according to different treatment methods. The response rate of non-surgical treatment, bowel function, observation time before surgery, postoperative complications and the recurrence rate were observed in both groups. RESULTS There was no significant difference in the response rate of non-surgical treatment and the incidence of postoperative complications between the two groups (P=0.257 and P=0.959, respectively). The observation time before surgery was shorter and the recurrence rate of obstruction was lower in the transnasal ileus intubation + radiography group than those in the nasogastric intubation group. The pain relief time, first flatus time and hospital stay were shorter in the transnasal ileus intubation + radiography group than those in the nasogastric intubation group, with statistically significant differences (all P<0.05). It was found that ascites and observation time before surgery were the influencing factors of surgical timing in patients with small bowel obstruction. CONCLUSION Transnasal ileus intubation is an effective treatment for small bowel obstruction. Radiography after transnasal ileus intubation is helpful to determine the optimal surgical timing for small bowel obstruction, shorten the postoperative recovery time and reduce the recurrence rate in patients, so it is recommended in clinical practice.

Abstract
Acute onset of abdominal pain with emesis and lack of stool or flatus is an alarming presentation for possible small bowel obstruction (SBO). SBO should be high on the differential diagnosis due to concomitant signs and symptoms that are highly sensitive in diagnosing SBO. These include diffuse tenderness on palpation of the abdomen, abdominal distention, hypotension, vomiting, and lack of flatus or stool. In this report, we present a 67-year-old African American male, who presented to the emergency department with the above-mentioned signs and symptoms and decreased oral intake for four days, ultimately undergoing surgical exploration to relieve the SBO caused by an idiopathic cecal perforation. This case report calls attention to the decision-making, standard protocol, and surgical intervention of a patient with SBO.

Imaging Signs for Determining Surgery Timing of Acute Intestinal Obstruction. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:1980371.

Abstract
We aimed to analyze the computed tomography (CT) imaging signs of bowel wall ischemia in patients with acute intestinal obstruction and construct an imaging prediction model to guide clinical treatment. The CT imaging signs of patients with acute intestinal obstruction diagnosed in our center in recent 6 years were collected for retrospective analysis. The etiology of intestinal obstruction and incidence rate of bowel wall ischemia were recorded, and the specific CT findings of bowel wall ischemia, including mesenteric edema, bowel wall thickening, and fish tooth sign, were analyzed. Among the 302 patients selected, 130 surgically treated patients were eligible for analysis. Bowel wall ischemia in acute intestinal obstruction showed an incidence rate of 14.90%, and the incidence rates of bowel wall ischemia in intra-abdominal hernia, intussusception, incarcerated external abdominal hernia, and volvulus were about 92.30%, 50%, 35.71%, 33.33%, and 12.59%, respectively. The incidence rate of bowel wall ischemia in simple adhesive intestinal obstruction was about 12.59%, and that in malignancy-induced intestinal obstruction was about 6.56%. Univariate analysis revealed 5 factors with statistical significance, including bowel wall thickening, mesenteric edema, bowel wall pneumatosis, ascites, and fish tooth sign. Multivariate logistic regression analysis indicated that fish tooth sign, bowel wall thickening, and mesenteric edema were able to predict bowel wall ischemia, and the corresponding partial regression coefficients were 2.164, 1.129, and 1.173, odds ratios (ORs) were 8.707, 3.093, and 3.232, sensitivity was 0.356, 0.400, and 0.844, and specificity was 0.859, 0.835, and 0.529, respectively. Imaging signs of bowel wall thickening, mesenteric edema, and fish tooth sign are valuable in predicting bowel wall ischemia, among which bowel wall thickening and mesenteric edema have relatively high specificity and fish tooth sign has a relatively high sensitivity. Furthermore, a fish tooth sign has the most favorable predictive value for bowel wall ischemia in acute intestinal obstruction, followed by bowel wall thickening and mesenteric edema.

Abstract
BACKGROUND Closed-loop small bowel obstruction (CL-SBO) can threaten the viability of the intestine by obstructing a bowel segment at two adjacent points. Prompt recognition and surgery are crucial.
AIM To analyze the outcomes of patients who underwent surgery for CL-SBO and to evaluate clinical predictors.
METHODS Patients who underwent surgery for suspected CL-BSO on computed tomography (CT) at a single center between 2013 and 2019 were evaluated retrospectively. Patients were divided into three groups by perioperative outcome, including viable bowel, reversible ischemia, and irreversible ischemia. Clinical and laboratorial variables at presentation were compared and postoperative outcomes were analyzed.
RESULTS Of 148 patients with CL-SBO, 28 (19%) had a perioperative viable small bowel, 86 (58%) had reversible ischemia, and 34 (23%) had irreversible ischemia. Patients with a higher age had higher risk for perioperative irreversible ischemia [odds ratio (OR): 1.03, 95% confidence interval (CI): 0.99-1.06]. Patients with American Society of Anaesthesiologists (ASA) classification ≥ 3 had higher risk of perioperative irreversible ischemia compared to lower ASA classifications (OR: 3.76, 95%CI: 1.31-10.81). Eighty-six patients (58%) did not have elevated C-reactive protein (> 10 mg/L), and between-group differences were insignificant. Postoperative in-hospital stay was significantly longer for patients with irreversible ischemia (median 8 d, P = 0.001) than for those with reversible ischemia (median 6 d) or a viable bowel (median 5 d). Postoperative morbidity was significantly higher in patients with perioperative irreversible ischemia (45%, P = 0.043) compared with reversible ischemia (20%) and viable bowel (4%).
CONCLUSION Older patients or those with higher ASA classification had an increased risk of irreversible ischemia in case of CL-SBO. After irreversible ischemia, postoperative morbidity was increased.

Abstract
Small bowel obstruction syndromes (SBO) represent one of the main causes of emergency admission for surgical abdominal pain. The 2018 Bologna Guidelines (Ten Broek et al. 2018) recommend non-operative management at the outset if there are no signs of severity; surgery is proposed after 72h for the 20-30% of patients who fail medical management. However, these recommendations were based on old studies published at a time when laparoscopic surgery was not commonplace and when diagnostic capabilities (particularly for establishing etiology) were less developed than they are today. Additionally, the advent and development of laparoscopy and enhanced rehabilitation after surgery have led to a decrease in surgical morbidity. These guidelines are therefore now debated and several recent publications have encouraged urgent or semi-urgent surgical management for patients presenting for SBO in order to reduce morbidity, mortality, duration of hospitalization and costs, and to improve the feasibility of therapeutic laparoscopy. Prompt surgical management could also reduce the risk of recurrent small bowel obstructions. This model for early surgical management probably cannot be applied to all patients. It therefore seems important to select those patients at risk for failure of medical treatment and to identify those in whom the probability of successful laparoscopy is high. New radiological tools should allow better selection in the future. At the present time, the indications for early surgery "within 24h" should be emphasized.

Abstract
PURPOSE Mechanical bowel obstruction (MBO) is one of the most common indications for emergency surgery. Recent research justifies the method of attempting 3-5 days of nonoperative treatment before surgery. However, little is known about specific characteristics of geriatric patients undergoing surgery compared to a younger cohort. We aimed to analyze patients with MBO that required surgery, depending on their age, to identify potential targets for use in the reduction in complications and mortality in the elderly. METHODS Thirty-day and in-hospital mortality were determined as primary outcome. We retrospectively identified all patients who underwent surgery for MBO at the University Hospital of Bonn between 2009 and 2019 and divided them into non-geriatric (40-74 years, n = 224) and geriatric (≥ 75 years, n = 88) patients, using the chi-squared-test and Mann-Whitney U test for statistical analysis. RESULTS We found that geriatric patients had higher 30-day and in-hospital mortality rates than non-geriatric patients. As secondary outcome, we found that they experienced a longer length of stay (LOS) and higher complication rates than non-geriatric patients. Geriatric patients who suffered from large bowel obstruction (LBO) had a higher rate of bowel resection, stoma creation, and a higher 30-day mortality rate. The time from admission to surgery was not shown to be crucial for the outcome of (geriatric) patients. CONCLUSION Geriatric patients suffering from mechanical bowel obstruction that had to undergo surgery had higher mortality and morbidity than non-geriatric patients. Especially in regard to geriatric patients, clinicians should treat patients in a risk-adapted rather than time-adapted manner, and conditions should be optimized before surgery.

Abstract
Being one of the most common causes of the acute abdomen, acute appendicitis (AA) forms the bread and butter of any general surgeon’s practice. With the recent advancements in AA’s management, much controversy in diagnostic algorithms, possible differential diagnoses, and weighing the management options has been generated, with no absolute consensus in the literature. Since Alvarado described his eponymous clinical scoring system in 1986 to stratify AA risk, there has been a burgeoning of additional scores for guiding downstream management and mortality assessment. Furthermore, advancing literature on the role of antibiotics, variations in appendicectomy, and its adjuncts have expanded the surgeon’s repertoire of management options. Owing to the varied presentation, diagnostic tools, and management of AA have also been proposed in special groups such as pregnant patients, the elderly, and the immunocompromised. This article seeks to raise the critical debates about what is currently known about the above aspects of AA and explore the latest controversies in the field. Considering the ever-evolving coronavirus disease 2019 situation worldwide, we also discuss the pandemic’s repercussions on patients and how surgeons’ practices have evolved in the context of AA.

Abstract
Introducción. Las adherencias postoperatorias son la causa más frecuente de obstrucción de intestino delgado. La clínica sugiere el diagnóstico, pero de manera poco precisa la causa y el sitio de la obstrucción. La tomografía computarizada contrastada es el estudio óptimo y permite identificar de manera oportuna a los pacientes que requieren intervención quirúrgica. El objetivo de este estudio fue analizar la correlación entre la clínica y el sitio de obstrucción detectado en la tomografía computarizada contrastada de abdomen, en pacientes con sospecha diagnóstica de obstrucción de intestino delgado por adherencias.
Métodos. Estudio prospectivo, transversal y analítico de pacientes con sospecha clínica de obstrucción de intestino delgado por adherencias y antecedentes quirúrgicos y su correlación con el sitio de obstrucción detectado en la tomografía computarizada de abdomen contrastada, de pacientes atendidos entre marzo de 2016 y febrero de 2019 en un hospital de segundo nivel.
Resultados. Se incluyeron 41 pacientes, la media de edad fue de 59 años y el género masculino el más comprometido (68,3 %, n=28); la ausencia de evacuaciones estuvo presente en 97,5 % (p=0,026). La tomografía computarizada contrastada mostró el sitio de obstrucción en 73 % de los pacientes y la localización de la obstrucción más prevalente fue en íleon distal (31,7 %, n=13). Se asoció a leucocitosis (p=0,041) y a dolor más intenso (p=0,049), sin presentar irritación peritoneal.
Conclusión. La obstrucción localizada en el íleon distal se caracterizó por presentar más dolor y mayor recuento leucocitario, sin correlación como factor de riesgo para requerir tratamiento quirúrgico.

Abstract
The evaluation of patients with pulmonary embolism (PE) requires a comprehensive approach that assesses physical and laboratory exam findings, interprets varying imaging modalities, and selects appropriate treatment strategies. Comorbidities can complicate treatment and influence physicians to make difficult management decisions. In this case report, we present a patient with a small bowel obstruction complicated by submassive intermediate high-risk PE. Stratifying risk in PE patients is crucial to gauge when to use invasive interventions. There is limited clinical data to identify the optimal timing of surgery in patients with concurrent PE. We describe a challenging case where a patient requires multiple life-saving interventions; however, each treatment method carries a risk of bleeding or further complicating surgical candidacy. The patient in question first undergoes treatment of PE to improve hemodynamics and lower the clot burden prior to proceeding with resection of the small bowel. This report emphasizes the utility of the Pulmonary Embolism Response Team to facilitate care when surgical comorbidities require immediate attention as well.

Abstract
A laparoscopic approach is suggested with the highest grade of recommendation for acute cholecystitis, perforated gastroduodenal ulcers, acute appendicitis, gynaecological disorders, and non-specific abdominal pain (NSAP). To date, the main qualities of laparoscopy for these acute surgical scenarios are clearly stated: quicker surgery, faster recovery and shorter hospital stay. For the remaining surgical emergencies, as well as for abdominal trauma, the role of laparoscopy is still a matter of debate. Patients might benefit from a laparoscopic approach only if performed by experienced teams and surgeons which guarantee a high standard of care. More precisely, laparoscopy can limit damage to the tissue and could be effective for the reduction of the overall amount of cell debris, which is a result of the intensity with which the immune system reacts to the injury and the following symptomatology. In fact, these fragments act as damage-associated molecular patterns (DAMPs). DAMPs, as well as pathogen associated molecular patterns (PAMPs), are recognised by both surface and intracellular receptors of the immune cells and activate the cascade which, in critically ill surgical patients, is responsible for a deranged response. This may result in the development of progressive and multiple organ dysfunctions, manifesting with acute respiratory distress syndrome (ARDS), coagulopathy, liver dysfunction and renal failure. In conclusion, none of the emergency surgical scenarios preclude laparoscopy, provided that the surgical tactic could ensure sufficient cleaning of the abdomen in addition to resolving the initial tissue damage caused by the “trauma”.

Abstract
Small bowel obstruction (SBO) is a common condition requiring urgent attention that may involve surgical treatment. Imaging is essential for the diagnosis and characterization of SBO because the clinical presentation and results of laboratory tests may be nonspecific. Ultrasound is an excellent initial imaging modality for assisting physicians in the rapid and accurate diagnosis of a variety of pathologies to expedite management. In the case of SBO diagnosis, ultrasound has an overall sensitivity of 92% (95% CI: 89–95%) and specificity of 93% (95% CI: 85–97%); the aim of this review is to examine the criteria for the diagnosis of SBO by ultrasound, which can be divided into diagnostic and staging criteria. The diagnostic criteria include the presence of dilated loops and abnormal peristalsis, while the staging criteria are represented by parietal and valvulae conniventes alterations and by the presence of free extraluminal fluid. Ultrasound has reasonably high accuracy compared to computed tomography (CT) scanning and may substantially decrease the time to diagnosis; moreover, ultrasound is also widely used in the monitoring and follow-up of patients undergoing conservative treatment, allowing the assessment of loop distension and the resumption of peristalsis.
