Primary Aortoenteric Fistula Due to Salmonella typhi-related Mycotic Aneurysm.

Primary aortoenteric fistulas (AEF) are rare. The majority of these are due to atherosclerotic aortic aneurysms. Mycotic aortic aneurysms leading to primary AEF are exceedingly uncommon. Here we report a rare case of primary AEF secondary to Salmonella-related mycotic aneurysm and discuss the diagnostic and therapeutic issues.

Colosplenic fistula diagnosis and management: a case series and review of literature.

BACKGROUND: A colosplenic fistula (CsF) is an extremely rare complication. Its diagnosis and management remain poorly understood, owing to its infrequent incidence. Our objective was to systematically review the etiology, clinical features, diagnosis, management, and prognosis to help clinicians gain a better understanding of this unusual complication and provide aid if it is to be encountered. METHODS: A systematic review of studies reporting CsF diagnosis in Ovid MEDLINE, Ovid EMBASE, Scopus, Web of Science, and Wiley Cochrane Library from 1946 to June 2022. Additionally, a retrospective review of four cases at our institution were included. Cases were evaluated for patient characteristics (age, sex, and comorbidities), CsF characteristics including causes, symptoms at presentation, diagnosis approach, management approach, pathology findings, intraoperative complications, postoperative complications, 30-day mortality, and prognosis were collected. RESULTS: Thirty patients with CsFs were analyzed, including four cases at our institution and 26 single-case reports. Most of the patients were male (70%), with a median age of 56 years. The most common etiologies were colonic lymphoma (30%) and colorectal carcinoma (17%). Computed tomography (CT) was commonly used for diagnosis (90%). Approximately 87% of patients underwent a surgical intervention, most commonly segmental resection (81%) of the affected colon and splenectomy (77%). Nineteen patients were initially managed surgically, and 12 patients were initially managed nonoperatively. However, 11 of the nonoperative patients ultimately required surgery due to unresolved symptoms. The rate of postoperative complications was (17%). Symptoms resolved with surgical intervention in 25 (83%) patients. Only one patient (3%) had had postoperative mortality. CONCLUSIONS: Our review of 30 cases worldwide is the largest in literature. CsFs are predominantly complications of neoplastic processes. CsF may be successfully and safely treated with splenectomy and resection of the affected colon, with a low rate of postoperative complications.

Robotic management of primary cholecystoduodenal fistula: A case report and brief literature review.

BACKGROUND: Cholecystoduodenal fistula (CDF) arises from persistent biliary tree disorders, causing fusion between the gallbladder and duodenum. Initially, open resection was common until laparoscopic fistula closure gained popularity. However, complexities within the gallbladder fossa yielded inconsistent outcomes. Advanced imaging and robotic surgery now enhance precision and detection. METHOD: A 62-year-old woman with chronic cholangitis attributed to cholecystoduodenal fistula underwent successful robotic cholecystectomy and fistula closure. RESULTS: Postoperatively, the symptoms subsided with no complications during the robotic procedure. Existing studies report favourable outcomes for robotic cholecystectomy and fistula closure. CONCLUSIONS: Our case report showcases a rare instance of successful robotic cholecystectomy with CDF closure. This case, along with a review of previous cases, suggests the potential of robotic surgery as the preferred approach, especially for patients anticipated to face significant laparoscopic morbidity.

[Primary aortoduodenal fistula - a rare cause of life-threatening upper gastrointestinal bleeding]. / Primär aortoduodenal fistel.

Primary aortoduodenal fistula is a rare condition caused mainly by a bulging infra-renal aortic aneurysm with subsequent erosion of the duodenum and formation of a fistula. We present a patient who suffered from a herald upper gastrointestinal bleeding followed by circulo-respiratory collapse only hours after, due to bleeding from the fistula. The mortality is reported to be 100 %, requiring emergency EVAR or open aortic graft repair to control any further bleeding.

Jejunovesical Fistula Diagnosis After Normal Vaginal Delivery: A Case Report.

Enterovesical fistula represents an abnormal communication between the intestine and bladder. The causes are diverticulitis (56.3%), malignant tumours, which are located mainly in the intestine (20.1%), and Crohn's disease (9.1%). Other causes include iatrogenic injury (3.2%); trauma; foreign bodies in the intestinal tract; radiotherapy; chronic appendicitis; tuberculosis; and syphilis. Normal vaginal delivery as a cause for enterovesical fistula has not been reported in many publications yet. We report a case of a 30-year-old female, who developed an jejunovesical fistula after normal vaginal delivery. It was diagnosed after diagnostic cystoscopy and computed tomography of the abdomen and pelvis. There was jejuno-vesical fistula. Resection of the segment of the jejunum with side-to-side anastomosis with bladder repair was done. A follow-up cystogram was done which showed no contrast extravasation into the peritoneum. The patient was followed up for 9 months after surgery. Keywords: case reports; fistula; jejunum; urinary bladder.

[The effectiveness of vacuum therapy and meglumine sodium succinate in unformed fistulas of the gastrointestinal tract (clinical observations)]. / Effektivnost' primeneniya vakuum-terapii i meglyumina natriya suktsinata pri nesformirovannykh svishchakh zheludochno-kishechnogo trakta (klinicheskie nablyudeniya).

The incidence of intestinal fistulas after laparotomy for various reasons (peritonitis, acute pancreatitis or trauma) is 1.5%. Fistula formation in patients with chronic gastrointestinal diseases has a rapid onset, severe course, and poor prognosis. Against the background of a long course of the disease and depletion of the body, there is a decrease in the activity of reparative processes, which leads to the manifestation of postoperative complications: the formation of fistulas, insolvency of intestinal anastomoses, peritonitis. Vacuum drainage is a treatment method aimed at eliminating exudate, reducing the area of the wound and its epithelization. The inclusion of a succinate-containing solution in the treatment regimen improves metabolic processes and improves the prognosis of the disease. As an illustration, a description of the clinical observation of patients with similar pathology and different treatment regimens is given.

Fístula sigmoido-glútea como complicación infrecuente de la enfermedad diverticular / Sigmoid-gluteal fistula as a rare complication of diverticular disease

Las fistulas colo-cutáneas de origen diverticular son poco frecuentes, máxime en ausencia de cirugía o drenaje percutáneo previos. Presentamos una mujer de 90 años con una sigmoitis complicada con una colección abdominal perforada hacia el retroperitoneo y la región glútea. (AU)

Colocutaneous fistulas of diverticular origin are rare, especially in the absence of prior surgery or percutaneous drainage. We report the case of a 90-year-old woman with sigmoitis and a perforated abdominal collection in the retroperitoneum and gluteal region. (AU)

Case report: a case report and literature analysis on intestinal tuberculosis intestinal perforation complicated by umbilical intestinal fistula and bladder ileal fistula.

BACKGROUND: Intestinal tuberculosis is a chronic and specific infection caused by Mycobacterium tuberculosis invading the intestine. Due to the nonspecific clinical presentation, it is stressed that intestinal perforation complicates umbilical intestinal fistula and bladder ileal fistula is very rare and extremely difficult to be diagnosed. It is significant to identify the disease and take urgent intervene in the early stage. CASE PRESENTATION: An 18-month-old boy patient presented with abdominal pain. Abdominal CT suggested abscess formation in the right lower abdomen and pelvis. The patient underwent resection of necrotic and stenotic intestinal segments with the creation of an ileostomy, cystostomy and vesicoureteral fistula repair for the presence of intestinal perforation complicated by vesicoureteral fistula and umbilical enterocutaneous fistula. Histopathology confirmed the intestinal tuberculosis. The patient was discharged successfully after 11 days post anti-tuberculosis treatment. CONCLUSION: Our case report here is a rare case of umbilical intestinal fistula with bladder ileal fistula secondary to intestinal perforation from intestinal tuberculosis. The purpose of this report is to make the surgical community aware of atypical presentations of intestinal tuberculosis. If our peers encounter the similar situation, they can be prepared for corresponding diagnosis and treatment.

Colorectal Malignancy Complicated by Arterioenteric Fistula.

Arterioenteric fistulas (AEF) are rare and devastating complications of colorectal/pelvic malignancies. These fistulas can be seen following neoadjuvant or adjuvant therapy but are exceptionally rare de novo. The reported incidence of AEF is less than 1% and iliac artery-enteric fistulas make up less than .1% of all AEF. Here we present a patient in hemorrhagic shock secondary to an advanced colorectal malignancy without adjuvant therapies with local invasion of the right external iliac artery. Following initial resuscitation and hemorrhage control with coil embolization, definitive control with ligation and excision of the involved artery, end colostomy, and ureteral stent placement was achieved. It is important to consider malignancy as the source of lower gastrointestinal bleeds, especially in elderly patients without current colonoscopy studies. The management of this unfortunate diagnosis often involves a multidisciplinary approach with early and frequent goals of care discussions.

Caracterización de las fístulas enterocutáneas posoperatorias / Characterization of Postoperative Enterocutaneous Fistulas

Introducción: Las fístulas enterocutáneas representan una enfermedad grave que deben afrontar un gran número de cirujanos durante el ejercicio de la profesión. El tratamiento suele ser extremadamente complejo y siempre requiere de una intervención multidisciplinaria adaptada para cada caso en particular. Objetivo: Evaluar las características clínico-epidemiológicas y terapéuticas de las fístulas enterocutáneas posoperatorias. Métodos: Se realizó un estudio observacional, descriptivo, con recogida prospectiva de datos en el quinquenio 2013-2017. El universo fue de 28 pacientes diagnosticados con fístula enterocutánea posoperatoria y se usaron las variables: edad, sexo, carácter de la intervención, diagnóstico operatorio, tipo de fístula, tratamiento definitivo, complicaciones y pilares de tratamiento. Resultados: La edad media fue de 49 años. Las fístulas fueron más frecuentes en el sexo femenino (53,57 por ciento). El 78,57 por ciento de los pacientes fueron intervenidos con carácter de urgencia, y el 25 por ciento tuvieron un diagnóstico operatorio de oclusión intestinal mecánica por bridas seguida de la oclusión intestinal por tumor de colon izquierdo (17,86 por ciento). La hemicolectomía izquierda con anastomosis término-terminal (21,43 por ciento) y la resección intestinal con anastomosis término-terminal (17,86 por ciento) fueron los principales procedimientos quirúrgicos realizados. Conclusiones: Las fístulas de tipo II y de bajo gasto prevalecieron en la serie de casos en una media de tiempo que se corresponde con lo reportado en la literatura. La infección del sitio quirúrgico fue la complicación más observada y los pilares del tratamiento fueron cumplidos en la mayoría de los pacientes prevaleciendo el cierre espontáneo como tratamiento definitivo(AU)

Introduction: Enterocutaneous fistulas are a serious disease that a large number of surgeons must face during the practice of their profession. Their treatment is usually extremely complex and always requires a multidisciplinary intervention adapted to each particular case. Objective: To evaluate the clinical-epidemiological and therapeutic characteristics of postoperative enterocutaneous fistulas. Methods: An observational and descriptive study was performed, with prospective data collection, in the five-year period 2013-2017. The study universe was 28 patients diagnosed with postoperative enterocutaneous fistula. The following variables were used: age, sex, nature of the intervention, operative diagnosis, type of fistula, definitive treatment, complications and treatment cornerstones. Results: The mean age was 49 years. Fistulas were more frequent in the female sex (53.57 percent). 78.57 percent of the patients underwent emergency surgery, while 25 percent had an operative diagnosis of mechanical intestinal occlusion due to adherences, followed by intestinal occlusion due to left colon tumor (17.86 percent). Left hemicolectomy with end-to-end anastomosis (21.43 percent) and intestinal resection with end-to-end anastomosis (17.86 percent) were the main surgical procedures. Conclusions: Type II and low-output fistulas prevailed in the case series at a mean time that corresponds to that reported in the literature. Surgical site infection was the most frequently observed complication, while the treatment cornerstones were fulfilled in most patients, with spontaneous closure prevailing as a definitive treatment(AU)

[Intraluminal endoscopy for biliary duodenal obstruction]. / Vnutriprosvetnaya endoskopiya pri biliarnoi duodenal'noi neprokhodimosti.

Cholelithiasis complicated by cholecystoduodenal fistula and small bowel biliary obstruction is an absolute indication for surgical treatment. Modern possibilities of intraluminal endoscopy (electrohydraulic lithotripsy) made it possible to avoid intra-abdominal access (laparotomy, laparoscopy) and postoperative complications. Finally, rapid rehabilitation was noted.

Development of an enterocutaneous fistula from an intestinal perforation in a patient with autosomal dominant polycystic kidney disease.

We herein report a case of enterocutaneous fistula in a patient with autosomal dominant polycystic kidney disease (ADPKD). A 37-year-old Japanese man was admitted to our hospital. Three months prior to transfer to our hospital, he developed intense flank pain with gross hematuria. His serum creatinine had decreased to 7.8 mg/dL and hemodialysis was started, but gross hematuria persisted and he developed hypotension. Upon admission, plain chest radiography did not reveal any free air, but computed tomography (CT) showed generalized ventral subcutaneous air from the head to the lower extremities and enlarged kidneys. Enterography showed leakage of contrast medium from the descending colon into the subcutaneous area. C-reactive protein was 23.1 mg/dL. A colostomy was placed in the transverse colon proximal to the perforation, and systemic subcutaneous drainage was performed. The fever subsequently resolved, and the C-reactive protein test became negative. Three months later, renal artery embolization was performed, and 12 months thereafter, CT showed a marked decrease in kidney size. We assume that a markedly enlarged kidney leaded to intestinal perforation, which developed into an enterocutaneous fistula. Consequently, intestinal fluid leaked into the subcutaneous cavity of the abdominal wall and spread systemically, resulting in extensive subcutaneous abscesses.

[A Case of Sigmoid Rectal Cancer with a Vesicoconstrictor Fistula Curatively Resected after Neoadjuvant Chemotherapy].

A 50-year-old man presented with fecaluria and was diagnosed with sigmoid colon cancer with a colovesical fistula. Total bladder resection was determined to be necessary for curative resection at the time of diagnosis. In anticipation of bladder preservation, 6 courses of mFOLFOX6 plus panitumumab were administered after transverse colostomy, resulting in marked tumor regression and a decision to proceed with surgery. The patient underwent robotic-assisted low anterior resection of the rectum and partial cystectomy, which yielded pathological radical treatment. We report a case of sigmoid colon cancer with a colovesical fistula complicated by bladder invasion, in which preoperative chemotherapy was effective and total cystectomy was avoided, allowing bladder preservation.
