[Nasogastric tube obstruction due to enteral feeding bezoar]. / Obstrucción de sonda nasogástrica por molde de nutrición enteral.

Introduction: Introduction: the administration of enteral nutrition through a nasogastric tube can cause potentially serious complications. We present a case of esophageal obstruction due to an enteral nutrition bezoar. Case report: the 77-year-old patient was admitted to our center in the intensive care unit for COVID pneumonia. The patient received enteral nutrition through a nasogastric tube (NGT), presenting difficulty passing it after a month of follow-up. After removal of the tube and attached to it, an esophageal mold for enteral nutrition was extracted. Later, a solvent solution is administered through a new SNG and the formula is modified for a hydrolyzed one. Discussion: enteral nutrition bezoars are a rare but can be a life-threatening complication.

An Unusual Small Bowel Phytobezoar Successfully Resolved by Double-balloon Enteroscopy.

We herein report a very unusual case of small bowel obstruction caused by phytobezoar in a 69-year-old woman who consumed a large amount of bracken. The patient presented with nausea and vomiting. Computed tomography revealed an air-filled foreign body in the jejunum that had likely caused the small bowel obstruction. A fibrous foreign body diagnosed as a phytobezoar was detected using double-balloon enteroscopy. The obstruction was successfully resolved by crushing the phytobezoar repeatedly using a snare. Small bowel obstructions caused by phytobezoars are often treated with surgical interventions. However, endoscopic fragmentation using a snare is a minimally invasive treatment alternative.

The value of MSCT in evaluating the passability of bezoar by conservative treatment for bezoars-induced small bowel obstruction.

PURPOSE: To explore the multi-slice spiral computed tomography (MSCT) imaging characteristics of patients with bezoars-induced small bowel obstruction (BI-SBO) to evaluate the risk of conservative treatment. MATERIALS AND METHODS: This retrospective study included 72 patients with BI-SBO who underwent whole-abdominal MSCT scan within 1 day before treatment. The patients were classified as the non-pass group and pass group depending on whether bezoar can pass after conservative treatment. The CT images were observed and measured by two radiologists. Statistical analysis was performed by using Student's t test, Pearson's chi-squared test, Fisher's exact test, Logistic linear regression, and receiver operating characteristic curve (ROC). RESULTS: The study population consisted of 72 patients with a mean age of 52.2 ± 16.2 years (32 men and 40 women with an age range of 13-81 years). There were statistical differences between the two groups in the bezoar appearance, maximum HU of bezoar, thickness of intestinal wall, mesenteric haziness, mesenteric fluid, and peritoneal fluid (P = 0.002, 0.024, 0.017, 0.006, 0.021, and 0.030). The appearance of bezoar and mesenteric haziness is independent risk factors affecting whether bezoar can be passed by the conservative treatment. Sensitivity (41.7%) was decreased, NPV (76.3%) was not significantly changed, specificity (93.8%) and PPV (76.9%) were improved when both parameters were met to assess failure of conservative treatment. CONCLUSION: The observation of important signs by MSCT and its reconstruction technology is of great clinical value in evaluating the passability of bezoar by conservative treatment, and which can provide radiographic basis for clinical treatment selection.

Failure of Computed Tomography (CT) in Detecting an Aspirin Pharmacobezoar: A Case Report.

BACKGROUND Prior studies suggest CT can identify bezoars under certain circumstances. Endoscopy provides diagnostic and therapeutic benefit in the setting of suspected aspirin bezoar. Does the absence of findings on CT scan exclude the presence of an aspirin bezoar? CASE REPORT A 64-year-old woman called the police and stated she ingested a bottle of aspirin to harm herself. Upon arrival to the Emergency Department, she was tachypneic with a GCS of 15. Initial laboratory results were: salicylate level of 1143 mcg/mL, respiratory alkalosis, bicarbonate of 9 meq/L, anion gap of 23, and normal renal function. Initial therapeutic intervention included infusions of glucose and bicarbonate, multiple doses of activated charcoal, intubation, and emergent hemodialysis. After hemodialysis, the salicylate level rebounded, and a Gastroenterology (GI) consultation was requested to rule out bezoar. On day 2, GI requested an abdominal CT scan with Gastrografin in place of endoscopy due to hemodynamic instability. A CT scan was negative for bezoar. After multiple hemodialysis sessions and whole-bowel irrigation with rebounding salicylate levels, GI was consulted again for reevaluation for endoscopy. On day 5, an endoscopy discovered a concretion containing pill fragments. Another endoscopy performed on day 7 removed further fragments. Salicylate levels began to consistently decline. Unfortunately, the patient's neurologic status did not improve, and on day 11 she was switched to palliative care and died. CONCLUSIONS Endoscopy with direct visualization is diagnostic and therapeutic in the setting of a possible bezoar. The absence of pharmacobezoar on imaging should not delay endoscopy in a clinical setting suggesting bezoar.

Esophageal pharmacobezoar: a very unusual complication of enteral nutrition use.

Enteral nutrition in intensive care has been a great advance in medicine, due to its benefit, cost-effectiveness and few complications. Bronchoaspiration, diarrhea, regurgitation or mechanical problems are the main adverse effects. Esophageal obstruction by bezoar is a very infrequent complication, and there are only a few cases described in the literature.

Fitobezoar disuelto químicamente con coca-cola / Chemically dissolved phytobezoar with coca-cola

Los bezoares han estado presentes en la historia de la medicina desde sus inicios, si bien su incidencia es baja y suelen detectarse de manera incidental, es importante tener opciones menos invasivas para su tratamiento debido a que la endoscopia digestiva alta (EDA) no está siempre disponible en todos los centros y, además, muchas veces no logra ser resolutiva debido al tamaño y/o composición del bezoar. En este reporte se presenta el caso de una paciente que, en el contexto de un posible síndrome de CREST, presentó un fitobezoar que fue disuelto con Coca-Cola®, un elemento ampliamente disponible alrededor del mundo, por lo que podría incluso llegar a considerarse como primera línea dentro del manejo no invasivo.

Bezoars have been present in the history of medicine since its inception, although their incidence is low and they are usually detected incidentally, it is important to have less invasive options for their treatment because upper digestive endoscopy (EDA) is not always available in all centers and, moreover, often fails to resolve due to the size and/or composition of the bezoar. This report presents the case of a patient who, in the context of a possible CREST syndrome, presented a phytobezoar that was dissolved with Coca-Cola®, an element widely available around the world, for which reason it could even be considered as the first line of non-invasive management.

Efficient treatment of esophageal nutrition bezoars: dissolution outmatches removal-the Zurich approach.

Enteral feed bezoars are difficult to treat and can lead to serious adverse events. There is no standardized treatment approach and various strategies have been suggested. We herein describe three cases of successful dissolutions of feed bezoars consisting of Promote® Fibre Plus with sodium bicarbonate 8.4% in critically ill patients. To provide the rationale for this approach, the effect of sodium bicarbonate 8.4% on enteral feed concretions was studied in vitro. First, Promote® Fibres Plus was incubated with hydrochloric acid with gradually decreasing pH values to establish a pH at which the solution solidifies. The resulting enteral feed concretion was exposed to sodium bicarbonate 8.4% and Coca Cola®. All patients were successfully treated with sodium bicarbonate 8.4% without the need of lengthy or repeat endoscopies. In vitro, Promote® Fibres Plus solidifies when acidified below a pH of 4.6. The resulting enteral feed concretions dissolved when exposed to sodium bicarbonate 8.4%. Incubation with Coca Cola® had no effect. We provide evidence that enteral feed bezoars consisting of Promote® Fibres Plus can be efficiently and safely treated with sodium bicarbonate 8.4% offering a new approach for daily patient care.

Bezoar gástrico, una aproximación al manejo / Gastric bezoar, an approach to medical management

The presence of bezoars in daily clinical practice is a event that poses a challenge both diagnostic, due to the associated factors in its development, as well as therapeutic. The management of this entity is associated with medical, endoscopic and surgical procedures and it is necessary to know its usefulness in different clinical scenarios. The role of carbonated beverages is increasingly accepted given its low cost, wide availability and high efficiency. For the aforementioned, it seems important to report a series of cases and the management performed.

La presencia de bezoares en la práctica clínica diaria es un evento que establece un desafío diagnóstico, por los factores asociados en su desarrollo, como también terapéutico. El manejo de esta patología se asocia a procedimientos médicos, endoscópicos y quirúrgicos siendo necesario conocer su utilidad en distintos escenarios clínicos. El rol de las bebidas carbonatadas es cada vez más aceptado dado su bajo costo, amplia disponibilidad y alta eficacia. Por lo antes señalado, nos parece importante reportar una serie de casos y el manejo realizado.

Clinical and Forensic Aspects of Pharmacobezoars.

BACKGROUND: Pharmacobezoars are specific types of bezoars formed when medicines, such as tablets, suspensions, and/or drug delivery systems, aggregate and may cause death by occluding airways with tenacious material or by eluting drugs resulting in toxic or lethal blood concentrations. OBJECTIVE: This work aims to fully review the state-of-the-art regarding pathophysiology, diagnosis, treatment, and other relevant clinical and forensic features of pharmacobezoars. RESULTS: Patients of a wide range of ages and of both sexes present with signs and symptoms of intoxications or more commonly gastrointestinal obstructions. The exact mechanisms of pharmacobezoar formation are unknown but are likely multifactorial. The diagnosis and treatment depend on the gastrointestinal segment affected and should be personalized to the medication and the underlying factor. A good and complete history, physical examination, image tests, upper endoscopy, and surgery through laparotomy of the lower tract are useful for diagnosis and treatment. CONCLUSION: Pharmacobezoars are rarely seen in clinical and forensic practice. They are related to controlled or immediate-release formulations, liquid, or non-digestible substances, in normal or altered digestive motility/anatomy tract, and in overdoses or therapeutic doses, and should be suspected in the presence of risk factors or patients taking drugs which may form pharmacobezoars.

Gastric phytobezoars: the therapeutic experience of 63 patients in Northern China

INTRODUCTION: Sixty-three patients with gastric phytobezoars were reviewed. METHODS: forty-eight (76.2%) patients received endoscopic combined with chemical therapies and 15 (23.8%) received only chemical therapy initially. Fifty-one (81.0%) patients achieved complete removal (only chemical therapy 14/15), while 12 (19.0%) received further endoscopic therapies. RESULTS: finally, 62 (98.4%) patients achieved a complete removal. Considering only patients with combined treatment as a first approach, treatment success was associated with a softer phytobezoar consistency (p = 0.023). CONCLUSION: in conclusion, most patients achieve a favorable outcome. Chemical therapy is useful in selected cases. Repeated endoscopic therapies may be needed in order to completely remove phytobezoars with a hard consistency

Coca-Cola®-Lyse eines Dünndarmileus durch intestinalen Phytobezoar.

Phytobezoars are rare causes for intestinal obstruction. Therapy options include surgical removal, enzyme treatment, endoscopic removal and lyis with Coca-Cola®. While there is ample literature about successful Coca-Cola®-lysis, little is to be found concerning intestinal beozars. In our case, neither surgical nor endoscopic treatment of the intestinal obstruction was possible, which is why we opted for a Coca-Cola®-lysis.

An Unusual Mimic of Intermittent Bowel Obstruction.

BACKGROUND Indigestible foreign material in the bowel can develop into bezoars. Intestinal obstruction can occur secondary to these bezoars. Phytobezoars specifically refer to those which accumulate as a result of undigested plant or other food material. CASE REPORT A 42-year-old woman presented to the Emergency Department with a several-month history of right-sided abdominal pain associated with bouts of vomiting. She had no other significant medical history. Labs and computed tomography were unrevealing. Gastroenterology was consulted and performed endoscopy. A foreign body resembling an undigested mini bell pepper was found near the terminal ileum. This was removed, and the patient later reported significant improvement in her symptoms. CONCLUSIONS Phytobezoars can lead to symptoms consistent with intestinal obstruction. The underlying pathology (e.g., masses, gastritis, adhesions, or dysmotility) can precipitate obstructions in the setting of bezoar formation. Surgical removal if often necessary for small-bowel obstructions secondary to bezoars, but in our case, fortunately, the foreign body was successfully removed during endoscopy.

[Rapunzel Syndrome Removed with Enteroscopy in a Child].

A trichobezoar is a type of bezoar that is composed of hair. In most cases, it is confined to the stomach, but in rare cases, it may extend to the small intestine. This condition is referred to as Rapunzel syndrome. The therapeutic method for bezoar removal depends on its type, location, and size. Generally, the treatment for Rapunzel syndrome involves surgical laparotomy. Endoscopic removal has also been effective in some cases. On the other hand, complications, such as respiratory difficulty and esophageal impaction may be encountered during endoscopic removal. Until now, the successful endoscopic removal of trichobezoars has been limited to the stomach or duodenum. This paper reports the case of a 4-year-old female patient with Rapunzel syndrome whose trichobezoar reached the proximal jejunum. The trichobezoar was removed without complications using an electrosurgical knife and snare through a single-balloon enteroscopy. The trichobezoar can be removed successfully using enteroscopy under general anesthesia without abdominal laparotomy in young children. Therefore, this method of removal can be considered preferentially for children with Rapunzel syndrome.
