Determining the need for surgery in small bowel obstructions based on clinical, laboratory, and radiological parameters.

OBJECTIVE: Small bowel obstruction (SBO) is a common and important surgical emergency. Our aim in this study is to describe the clinical, laboratory, and computed tomography (CT) findings to facilitate the objective identification of SBO patients in need of operative treatment in this patient population. METHODS: This retrospective study included 340 patients hospitalized due to a preliminary diagnosis of ileus. Retrieved data of patients included age, gender, comorbidities, previous hospitalization due to ileus, surgical history, physical examination findings, complete blood count and biochemistry test results, and CT findings at admission. RESULTS: The study included 180 (52.9%) male and 160 (47.1%) female patients. Treatment was conservative in 216 patients and surgery in 124 patients. Of the patients included in the study, 36.4% needed surgery. Of the female patients, 38.90% received conservative treatment and 61.30% underwent surgery. Adhesions were the most common cause of obstruction in operated patients (43.50%). CONCLUSION: We have found that female gender, vomiting, guarding, rebound, C-reactive protein levels above 75 mg/L, increased bowel diameter, and a transition zone on CT images indicate a strong need for surgery, but a history of previous hospitalization for ileus may show that surgery may not be the best option.

OBJETIVO: Describir los hallazgos clínicos, de laboratorio y de tomografía computarizada (TC) para facilitar la identificación objetiva de los pacientes con obstrucción del intestino delgado que necesitan tratamiento quirúrgico. MÉTODO: Este estudio incluyó 340 pacientes. Los datos obtenidos fueron edad, sexo, comorbilidad, hospitalización previa debida a íleo, historia quirúrgica, hallazgos de la exploración física, hemograma completo y resultados de las pruebas bioquímicas, y hallazgos de la TC al ingreso. RESULTADOS: El estudio incluyó 180 (52.9%) varones y 160 (47.1%) mujeres. El tratamiento fue conservador en 216 pacientes y quirúrgico en 124 pacientes. De los pacientes incluidos en el estudio, el 36.4% necesitaron cirugía. De las mujeres, el 38.90% recibieron tratamiento conservador y el 61.30% se sometieron a cirugía. CONCLUSIONES: Encontramos que el sexo femenino, los vómitos, la guardia, el rebote, los niveles de proteína C reactiva superiores a 75 mg/l, el aumento del diámetro intestinal y una zona de transición en las imágenes de TC indican una fuerte necesidad de cirugía.

Can direct bilirubin-to-lymphocyte ratio predict surgery for pediatric adhesive small bowel obstruction?

OBJECTIVE: Estimating which patients might require surgical intervention is crucial. Patients with complete bowel obstructions exhibit disrupted enterohepatic cycles of bile and bacteremia due to bacterial translocation. The goal of this study was to develop a prediction index using laboratory inflammatory data to identify patients who may need surgery. MATERIALS AND METHODS: The patients were divided into two groups based on their management strategy: Non-operative management (Group 1) and surgical management (Group 2). RESULTS: The indirect bilirubin, direct bilirubin, and total bilirubin were significantly higher in Group 2 than in Group 1 (p = 0.001, p < 0.001, and p < 0.001, respectively). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-NLR (PNLR), and direct bilirubin-to-lymphocyte ratio (DBR) were significantly higher in Group 2 compared to Group 1 (p = 0.041, p = 0.020, and p < 0.001, respectively). In group 2, 78% have viable bowels. Resection was performed in 40% of cases, with 12% mortality and a 10-day average hospital stay. DLR performs the best overall accuracy (72%), demonstrating a well-balanced sensitivity (62%) and specificity (81%). CONCLUSIONS: This study suggested that DBR is a more accurate predictive index for surgical intervention in pediatric adhesive small bowel obstruction patients compared to NLR and PNLR, providing valuable guidance for treatment strategies.

OBJETIVO: Desarrollar un índice de predicción utilizando datos inflamatorios de laboratorio para identificar qué pacientes podrían necesitar cirugía. MÉTODO: Los pacientes se dividieron en dos grupos según su estrategia de manejo: no quirúrgico (grupo 1) o quirúrgico (grupo 2). RESULTADOS: Las bilirrubinas indirecta, directa y total fueron significativamente más altas en el grupo 2 que en el grupo 1 (p = 0.001, p < 0.001 y p < 0.001, respectivamente). Las relaciones neutrófilos-linfocitos, plaquetas-neutrófilos-linfocitos y bilirrubina directa-linfocitos fueron significativamente más altas en el grupo 2 que en el grupo 1 (p = 0.041, p = 0.020 y p < 0.001, respectivamente). En el grupo 2, el 78% tenían intestino viable. Se realizó resección en el 40% de los casos, con un 12% de mortalidad y una estancia hospitalaria promedio de 10 días. La relación bilirrubina directa-linfocitos tuvo la mejor precisión general (72%), demostrando una sensibilidad bien equilibrada (62%) y una buena especificidad (81%). CONCLUSIONES: Este estudio sugiere que la relación bilirrubina directa-linfocitos es un índice predictivo más preciso para la intervención quirúrgica en pacientes pediátricos con obstrucción adhesiva de intestino delgado en comparación con la de neutrófilos-linfocitos y la de plaquetas-neutrófilos-linfocitos, proporcionando una valiosa orientación para las estrategias de tratamiento.

When a gastrostomy tube goes missing, acute bowel obstruction due to a migrated Foley catheter.

A gastrostomy is a common procedure for patients with swallowing problems or inability to maintain regular oral nutrition. These gastrostomy tubes need special attention, as complications can occur if the tubes are left unattended. In rare scenarios, these tubes can migrate and cause severe life-threatening difficulties such as bowel obstruction and pancreatitis. We present the case of a 76-year-old quadriplegic woman who had a gastrostomy tube. Suddenly, the tube was missing, and after urgent medical care, the gastrostomy tube was found within her bowel. After successful surgery, she recovered from this incident.

Long-term outcomes of the obstruction treatment in benign and malignant colonic obstruction: a multicentre study

Introduction: Patients with colonic obstruction are at risk for emergency resection, which is a risk factor for increased mortality and morbidity. In left-sided obstructive colon cancer, the principle of bridge-to-surgery is already recommended to reduce complications. From this treatment strategy, the obstruction treatment is derived. In this treatment strategy, bowel wall distention is reduced by minimizing stool production through laxatives and dietary measures. Short-term outcomes have already shown promising results. This study aims to evaluate long-term outcomes in patients treated with this obstruction treatment. Methods: This is a multicenter prospective study that included patients who presented with symptomatic colonic obstruction and radiologic confirmation of obstruction between May 2019 and August 2020 in the contributing hospitals. Patients with malignant and benign colonic obstruction were included. Follow-up in this study consisted of at least 36 months. Endpoints of the study included 1- and 3-year stoma and mortality rates. Results: Ninety-eight patients were included in this study. For the overall cohort complication, reoperation, and readmission rates after one year were 37%, 14%, and 10% respectively. Overall, 3-year mortality was 21%. The presence of a stoma after 1 year was 18%, and after 3 years 17% in this cohort. Conclusion: Long-term results of this study indicate that obstruction treatment has acceptable long-term outcomes in terms of mortality and stoma rates, compared to literature on emergency surgery and bridge-to-surgery alternatives. Permanent stoma rates are lower, compared to the literature on other treatment strategies in bowel obstruction. (AU)

Retroperitoneal aortoaortic bypass for treatment of aortoduodenal syndrome.

Aortoduodenal syndrome is a rare clinical entity characterized by extrinsic compression of the duodenum by an abdominal aortic aneurysm. The current surgical standard involves open aneurysm repair in a transperitoneal fashion. We describe a case of a 69-year-old man diagnosed with this syndrome who underwent successful repair using a retroperitoneal approach. The postoperative outcomes included early initiation of an oral diet, improved nutritional status, and a shorter hospital stay. We also describe the rationale leading to our decision and advocate the use of retroperitoneal surgery as the standard of care for patients presenting with aortoduodenal syndrome.

Enterocutaneous fistula due to a Richter's hernia after a Tenckhoff catheter removal.

Richter's hernia is a rare type of hernia that occurs when the antimesenteric intestinal wall protrudes through a defect in the abdominal fascia leading to ischaemia, gangrene, bowel perforation and enterocutaneous fistulae. In this article, we describe a rare case of enterocutaneous fistula due to a Richter's hernia after a Tenckhoff catheter removal. This type of complication has not been previously reported in the literature. An 82-year-old man presented with a 1-day history of enteric content at the Tenckhoff catheter insertion site. Seven weeks earlier, the catheter was removed due to peritonitis. Removal was performed using open technique, and the fascia was not closed. Computed tomography revealed a small incarcerated hernia and subcutaneous fluid collection at the previous catheter insertion site. He underwent laparoscopy, which showed a Richter's hernia with perforation of the ileum causing an enterocutaneous fistula. A laparoscopic enterectomy was performed using a primary mechanical anastomosis. The hernia was repaired by primary suture without a mesh because of wound enteral contamination and the small size of the hernia. Richter's hernia has a misleading clinical presentation and contributes to high rates of morbidity and mortality. A secure myofascial closure during catheter removal may reduce the chances of this complication.

Intususcepción intestinal por linfoma de Burkitt en un paciente adulto. Primer reporte en Latinoamérica.

Intestinal intussusception is a pathology in which an intestinal segment and its mesentery are telescoped into an adjacent intestinal segment as a result of peristalsis, and in many cases cause intestinal obstruction. Its etiology can be variable, including intestinal diverticula, adhesion bands, vascular malformations, neoplasms, among others. The vast majority occur in pediatric patients, however, up to 5% of these are documented in adult patients and their main etiology in this age group are neoplasms. We present a case of intestinal intussusception secondary to Burkitt's lymphoma that received management at fourth level hospital in Bogotá, Colombia.

La intususcepción intestinal es una patología en la que un segmento intestinal y su mesenterio se invaginan al segmento intestinal contiguo. Su etiología puede ser benigna, maligna o idiopática, dentro de las que se incluyen divertículos intestinales, bandas adherenciales, malformaciones vasculares y neoplasias, entre otras. La mayoría se presentan en pacientes pediátricos, pero hasta un 5% se documentan en pacientes adultos y su principal etiología en este grupo etario son las neoplasias. Presentamos un caso de intususcepción intestinal secundaria a linfoma de Burkitt que recibió manejo en un hospital de cuarto nivel en Bogotá, Colombia.

Do not open wide; accidentally swallowed dental mold causing bowel obstruction. A case report.

Foreign body ingestion is a common condition in daily practice; fortunately, most cases do not require endoscopic or surgical treatment, as most foreign bodies pass through the intestine without injuring it. Although mainly seen in children, adults can also be affected, especially in accidental situations and suicide attempts. Therefore, the clinical history and the environment in which the event occurred are essential for a rapid diagnosis. This can be even more challenging as most adult patients are rarely aware of ingestion. Therefore, a high index of suspicion is necessary. Therapy will depend on the foreign body's size, shape and material; treatment should not be delayed if complications are detected. We present a case of a 34-year-old man who accidentally swallowed the mold of his teeth while undergoing a dental procedure. Subsequently, he presented with an intestinal obstruction that required surgery. Fortunately, he made a full recovery.

Brazilian Society of Surgical Oncology guidelines for malignant bowel obstruction management.

BACKGROUND: Malignant bowel obstruction (MBO) is a frequent complication in advanced cancer patients and especially those with abdominal tumors. The clinical management of MBO requires a specific and individualized approach based on the disease prognosis. Surgery is recommended. Less invasive approaches such as endoscopic treatments should be considered when surgery is contraindicated. The priority of care for inoperable and consolidated MBO is to control the symptoms and promote the maximum level of comfort. OBJECTIVES: This study aimed to develop recommendations for the effective management of MBO. METHODS: A questionnaire was administered to all members of the Brazilian Society of Surgical Oncology, of whom 41 surgeons participated in the survey. A literature review of studies retrieved from the National Library of Medicine database was conducted on particular topics chosen by the participants. These topics addressed questions regarding the MBO management, to define the level of evidence and strength of each recommendation, and an adapted version of the Infectious Diseases Society of America Health Service rating system was used. RESULTS: Most aspects of the medical approach and management strategies reviewed were strongly recommended by the participants. CONCLUSIONS: Guidelines outlining the strategies for management MBO were developed based on the strongest evidence available in the literature.

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.

Clinical and tomographic features associated with surgical management in adhesive small bowel obstruction patients.

BACKGROUND: The delay in surgical management of intestinal obstruction patients who did not respond to conservative management increases morbidity, mortality and days of hospital stay. OBJECTIVE: This study aimed to describe the clinical and tomographic features associated with surgical management in adhesive small bowel obstruction patients. METHOD: We conducted a retrospective review of the electronic medical records during a 5-year period with the diagnosis of adhesive small bowel obstruction. We divided patients in two, those who responded to medical management and those who required surgery. RESULTS: A total of 162 patients were included, with a mean age of 61.5 years. It was the first case of intestinal obstruction in 63% of the patients and 65.4% underwent surgery: 52.8% (n = 56) open surgery and 47.2% (n = 50) laparoscopic surgery. Multivariate analysis showed the following predictors of surgical treatment: abdominal rebound (odds ratio [OR]: 8.8; 95% confidence interval [95% CI]: 1.09-71.6), tomographic free fluid (OR: 4.62; 95% CI: 1.50-14.20) and transition zone (OR: 5.4; 95% CI: 1.59-18.80). The history of previous obstruction was a protective factor (OR: 0.33; 95% CI: 0.17-0.67). CONCLUSIONS: Abdominal rebound, free intrabdominal fluid and transition zone are related with the surgical management of adhesive small bowel obstruction.

ANTECEDENTES: El retraso en el manejo quirúrgico de los pacientes con oclusión intestinal aumenta la morbimortalidad y los días de estancia intrahospitalaria. OBJETIVO: Describir las características clínicas y tomográficas de ingreso asociadas al manejo quirúrgico en pacientes con oclusión intestinal adherencial. MÉTODO: Revisamos los expedientes electrónicos de pacientes de los últimos 5 años con diagnóstico de oclusión intestinal adherencial y los dividimos según recibieran tratamiento conservador o tratamiento quirúrgico, y comparamos las variables. RESULTADOS: Cumplieron los criterios de inclusión 162 pacientes, con una edad media de 61.5 años. El episodio capturado fue el primer episodio de oclusión intestinal en el 63% de los pacientes. Se realizó tratamiento quirúrgico al 65.4% de los pacientes (n = 106): 52.8% (n = 56) cirugía abierta y 47.2% (n = 50) cirugía laparoscópica. El análisis multivariado mostró los siguientes factores predictores de tratamiento quirúrgico: presencia de rebote abdominal (odds ratio [OR]: 8.8; intervalo de confianza del 95% [IC95%]: 1.09-71.6), líquido libre (OR: 4.62; IC95%: 1.50-14.20) y zona de transición por tomografía (OR: 5.4; IC95%: 1.59-18.80). El antecedente de oclusiones previas fue un factor protector (OR: 0.33; IC95%: 0.17-0.67). CONCLUSIONES: El rebote abdominal, el líquido libre y la presencia de zona de transición por tomografía están asociados al manejo quirúrgico en los pacientes con oclusión intestinal adherencial.

Cecocolic intussusception and cecal torsion in cattle / Intussuscepção cecocólica e torção de ceco em bovinos

This work aims to describe the clinical, laboratory, and anatomopathological findings of two bovines, one affected by cecocolic intussusception, and the other by dilation with cecal torsion. The clinical examination demonstrated metallic resonance from the right flank, ruminal and intestinal hypomotility, and abdominal distension, in addition to alterations in feces characteristics. Was observed in the two animals leukocytosis by neutrophilia with regenerative shift to the left, and hyperfibrinogenemia. The analysis of ruminal fluid revealed impairment of the microbiota and an increase in chloride levels. The laparoscopic examination performed on one of the animals showed dilation of the colon, the cecum with hyperemia and serous edema, with a dividing halo between affected and unaffected portions, in addition to reddish peritoneal fluid. In the laparotomy, an enlarged cecum was found, with gaseous and liquid contents, swollen and turgid colon, and peritonitis. In addition to the findings observed during surgery, the anatomopathological examination demonstrated, in bovine 01, intestinal intussusception in the region of the cecocolic valve, and, in bovine 02, twisting of the loop at the ileocecocolic junction. Despite the low occurrence of digestive system disorders in cattle, cecal torsion and intussusception represent serious intestinal clinical conditions. These reports take the attention to the importance of a multidisciplinary approach to provide a correct diagnosis of intestinal diseases.(AU)

O objetivo deste trabalho foi descrever os achados clínicos, laboratoriais e anatomopatológicos de dois bovinos, um acometido por intussuscepção cecocólica e o outro por dilatação com torção de ceco. O diagnóstico de ambos os casos foi base-ado nos achados clínicos, laboratoriais, videolaparoscópicos, cirúrgicos e anatomopatológicos. No exame clínico evidenciou-se ressonância metálica no flanco direito, hipomotilidade ruminal e intestinal, distensão abdominal, além de alteração nas carac-terísticas das fezes. Observou-se nos dois animais leucocitose por neutrofilia com desvio para esquerda regenerativo e hiperfi-brinogenia. A análise do fluido ruminal revelou comprometimento da microbiota e elevação nos teores de cloretos. O exame videolaparoscópico, realizado no bovino dois (02), evidenciou dilatação do cólon, ceco com hiperemia e edema de serosa com halo divisório entre porção acometida e não acometida, além de líquido peritoneal de coloração avermelhada. Na laparotomia constatou-se ceco dilatado por conteúdo gasoso e líquido, cólon edemaciado e túrgido e, peritonite. No exame anatomopato-lógico, constatou-se, no bovino um (01), intussuscepção intestinal na região de válvula ceco-cólica e, no bovino (02) torção de alça na junção ileocecocólica. Apesar da baixa ocorrência, a torção de ceco e a intussuscepção acarretam condição intestinal grave e devem ser inseridas na lista de diagnósticos diferenciais das enfermidades digestivas de bovinos. Estes relatos chamam a atenção para a importância da abordagem multidisciplinar no diagnóstico das enfermidades intestinais.(AU)

Small bowel obstruction following laparoscopic Roux-en-Y gastric bypass: is it always necessary to operate? A 5-year, high volume center experience.

PURPOSE: This study aims to describe the incidence, associated factors, etiology, and management of small bowel obstructions following laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: A retrospective analysis was conducted between January 15 and December 19 using the surgery database of our hospital. Included LRYGB patients were those that evolved with a prolonged length of stay; readmission; emergency room consult; and re-intervention due to small bowel obstruction (SBO) related symptoms with compatible radiological or intraoperative findings. The LRYGB technique implied an antecolic alimentary limb reconstruction and systematic closure of mesenteric defects. Descriptive and analytical statistics were carried out, using a parametric or non-parametric approach as needed. RESULTS: Nine hundred forty-one LRYGB were performed. 9.9% were revisional surgeries of patients with a laparoscopic sleeve gastrectomy. During the study period, 36 SBOs occurred, representing 3.8% of operated patients, with no mortality. 58.3% had successful non-operative management, while 41.7% required surgical exploration, of which 73.3% were treated laparoscopically and 20% needed conversion to open surgery. Etiologies of SBO were jejuno-jejunostomy (JJO) related stenosis (22, 61.1%), internal hernias (6, 16.7%), adherences (3, 8.3%), and other diagnoses (5, 13.9%). Regarding JJO stenosis and internal hernias, median time to diagnosis was 8 days (IQR 7-11) and 12 months (IQR 8.7-16) respectively. Previous sleeve gastrectomy, age, or sex was not associated to the incidence of small bowel obstruction. CONCLUSIONS: LRYGB is safe when performed by experienced surgeons. SBO due to internal hernias were scarce in this series. JJO stenosis could explain most cases of SBO; under this diagnosis, non-surgical management was successful frequently.

Ileocolonic intussusception due to severe endometriosis.

Endometriosis is the presence of normal endometrial tissue outside the uterus, which may appear in up to 15% of fertile female population. Bowel endometriosis is uncommon, and obstruction due to endometrial ileocolic intussusception is extremely rare. Herein, we report a case of a 27-year-old female who presented with bowel obstruction due to ileocolic intussusception secondary to endometriosis. A 27-year-old female, without pregnancies, and with a 1 year history of endometriosis presented to the emergency department referring severe abdominal pain in right lower quadrant, nausea and vomiting, she had medical history of prior episodes of mild abdominal pain due to endometriosis with OB/GYN follow-up. Physical examination revealed abdominal distension with decreased bowel movements to auscultation. A CT scan reported suspicion of intussusception. Colonoscopy was ordered, where an ileocolic intussusception was found. Diagnostic laparoscopy was performed, and the initial diagnosis was confirmed. A right hemicolectomy with extracorporeal anastomosis was achieved without any surgical complications. The patient was discharge on postoperative day 4 and continues doing well on a 12 month follow-up. Ileocolic intussusception due to endometriosis is a very rare condition, and it must be considered a differential diagnosis in female patients in reproductive age, when presenting with intestinal obstruction.

Obstrucción intestinal, complicación inusual por banda gástrica ajustable laparoscópica: reporte de caso / Small Bowel Obstruction as a Rare Complication After Laparoscopic Adjustable Gastric Banding: A Case Report

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.

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.
