При длительном камненосительстве у ряда пациентов наблюдаются осложнения в виде формирования билиодигестивных соустий. Неполные свищи встречаются относительно реже и их диагностика бывает иногда затруднительна в связи с разнообразной клинической картиной</p></sec><sec><title>Клиническое наблюдение</title><p>Клиническое наблюдение. В статье представлено клиническое наблюдение редкой формы осложнения желчекаменной болезни – неполного холецистогастрального свища с симуляцией подслизистой опухоли антрального отдела желудка. Пациентка 72 лет поступила на плановое оперативное лечение по поводу хронического калькулезного холецистита. Камень желчного пузыря обнаружен более 10 лет назад, очередное обострение заболевания возникло месяц назад после приема жирной и жареной пищи. По данным мультиспиральной компьютерной томографии получены признаки объемного образования пилорического отдела желудка с признаками инфильтративного роста в стенку желчного пузыря. В условиях оперативного вмешательства установлен неполный холецистогастральный свищ. Выполнена холецистэктомия. Обнаружен дефект в стенке антрального отдела желудка, где в подслизистом слое обнаружен конкремент размером 15×10×10 миллиметров, симулирующий объемное образование антрального отдела желудка. Дефект в стенке желудка ушит. Послеоперационный период протекал благоприятно. Заживление ран первичным натяжением. Пациентка в удовлетворительном состоянии выписана на 8 сутки. При контрольном обследовании через 3 месяца состояние удовлетворительное.</p></sec><sec><title>Заключение</title><p>Заключение. Особенность данного клинического наблюдения: трудности диагностики редкого варианта билиодигестивного соустья – неполного холецистогастрального свища с симуляцией подслизистой опухоли антрального отдела желудка.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Cholelithiasis is one of the most common gastrointestinal diseases. In case of long-term stone carriage, some patients experience complications in the form of biliodigestive anastomoses. Incomplete fistulas are relatively rare and their diagnosis is sometimes difficult due to the diverse clinical picture.</p></sec><sec><title>Case descriptions</title><p>Case descriptions.  The article presents a clinical observation of a rare complication of cholelithiasis - incomplete cholecystogastric fistula with simulation of a submucosal tumor of the antrum of the stomach. A 72-year-old female patient was admitted for planned surgical treatment for chronic calculous cholecystitis. The gallstone was detected more than 10 years ago, the next exacerbation of the disease occurred 1 month ago after eating fatty and fried foods. According to multispiral computed tomography, signs of a space-occupying lesion of the pyloric part of the stomach with signs of infiltrative growth into the wall of the gallbladder were obtained. During surgery, an incomplete cholecystogastric fistula was established. Cholecystectomy was performed. A defect in the wall of the antrum of the stomach was detected, where a calculus measuring 15x10x10 mm was found in the submucosal layer, simulating a space-occupying lesion of the antrum of the stomach. The defect in the wall of the stomach was sutured. The postoperative period was favorable. Wound healing by primary intention. The patient was discharged in satisfactory condition on the 8th day. During the control examination after 3 months, the condition was satisfactory.</p></sec><sec><title>Conclusion</title><p>Conclusion. The peculiarity of this clinical observation: difficulties in diagnosing a rare variant of biliodigestive anastomosis - an incomplete cholecystogastric fistula with a simulation of a submucosal tumor of the antrum of the stomach.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>редкое наблюдение</kwd><kwd>желчнокаменная болезнь</kwd><kwd>холецистогастральный свищ</kwd><kwd>подслизистая опухоль желудка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rare observation</kwd><kwd>cholelithiasis</kwd><kwd>cholecystogastric fistula</kwd><kwd>difficult diagnosis</kwd><kwd>submucous tumor of the stomach</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mendoza-Vélez M.L.Á., Cárdenas-Lailson L.E., Barlandas-Quintana E., Zubillaga-Mares A.
