A secondary abdominal aorta-duodenal fistula accompanied with acquired Immune Deficiency Syndrome presented with recurrent sepsis: a case report.

BACKGROUND: Abdominal aorta-duodenal fistulas are rare abnormal communications between the abdominal aorta and duodenum. Secondary abdominal aorta-duodenal fistulas often result from endovascular surgery for aneurysms and can present as severe late complications. CASE PRESENTATION: A 50-year-old male patient underwent endovascular reconstruction for an infrarenal abdominal aortic pseudoaneurysm. Prior to the operation, he was diagnosed with Acquired Immune Deficiency Syndrome and Syphilis. Two years later, he was readmitted with lower extremity pain and fever. Blood cultures grew Enterococcus faecium, Salmonella, and Streptococcus anginosus. Sepsis was successfully treated with comprehensive anti-infective therapy. He was readmitted 6 months later, with blood cultures growing Enterococcus faecium and Escherichia coli. Although computed tomography did not show contrast agent leakage, we suspected an abdominal aorta-duodenal fistula. Esophagogastroduodenoscopy confirmed this suspicion. The patient underwent in situ abdominal aortic repair and received long-term antibiotic therapy. He remained symptom-free during a year and a half of follow-up. CONCLUSIONS: This case suggests that recurrent infections with non-typhoidal Salmonella and gut bacteria may be an initial clue to secondary abdominal aorta-duodenal fistula.

Reno-Duodenal Fistula as a Complication of Staghorn Stones and Renal Pelvis Tumor: A Case Presentation.

Reno alimentary fistula, a rare illness characterized by improper connection between the kidney and digestive tract, can lead to urinary tract infections, abscesses, and severe sepsis. It can also be caused by various factors such as chronic infections, malignancy, cryoablation, or abdominal surgical procedures. We present a case of a 60-year-old man with bilateral staghorn stones who was diagnosed with reno-duodenal fistula and underwent a right simple nephrectomy and fistula closure. The histopathology revealed a well-differentiated squamous cell carcinoma that originated from the renal pelvis.

Delayed duodenal/gastric fistula resulting in persistent perihepatic abscesses as a late complication of laparoscopic cholecystectomy.

Since the early 1990's, laparoscopic cholecystectomy has become the gold standard for the treatment of symptomatic gallbladder disease. Although the incidence of postoperative complications is generally lower with this approach, gallbladder perforation represents a serious risk that is among the most common complications of laparoscopic cholecystectomy. The sequalae that can follow iatrogenic perforation have not been well documented and only a few case reports exist in the current literature. In this paper we discuss two case reports of delayed perihepatic abscesses following prior laparoscopic cholecystectomy, ultimately resulting in fistulous tracts. The course of the disease is discussed along with the diagnostic workup and eventual successful management of the aforementioned complications. Treating enteric fistulae requires a systematic approach and is carried out in phases. Enteric fistula formation following laparoscopic cholecystectomy is a rare complication of retained gallstones that can present months to years following the index operation. Significant care should be taken to avoid perforation and all efforts should be made to retrieve stones if spillage occurs.

Transduodenal robotic ampullectomy: tips and tricks and strategies for postoperative duodenal fistula management (with video).

Transduodenal Ampullectomy (TA) is a procedure for resecting low-malignancy ampullary tumors, with postoperative fistula as a notable complication. This study aims to clarify the indications for TA, outline the surgical robotic technique, and emphasize the importance of comprehensive complication management alongside the surgical approach. This multimedia article provides a detailed exposition of the robotic TA surgical technique, including the most important steps involved in exposing and reimplanting biliary and pancreatic ducts. The procedure encompasses the mobilization of the hepatic flexure of the colon, an extensive Kocher maneuver for duodenal mobilization, and ampulla exposure through a duodenal incision. Employing retraction loop sutures enhances surgical field visibility. Reconstruction involves securing pancreatic and biliary ducts to the duodenal mucosa, each tutored with a silicon catheter, and suturing for ampullectomy completion. The total operative time was 380 min. Final histopathology disclosed high-grade dysplasia with an isolated focus of adenocarcinoma (pT1), accompanied by clear resection margins. A postoperative duodenal fistula occurred, managed successfully through conservative treatment, utilizing subcutaneous drainage. Despite accurate robotic TA execution, complications may arise. This study underscores the importance of a comprehensive approach, incorporating meticulous surgical technique and effective complication management, to optimize patient outcomes.

Pancreatic Tuberculosis With Duodenal Fistula Presenting as Life-Threatening Gastrointestinal Bleeding.

Pancreatic tuberculosis (TB) warrants heightened suspicion in individuals with pancreatic lesions and risk factors such as HIV, organ transplantation, or pertinent immigration history. We present a 38-year-old man who presented with hemodynamically unstable gastrointestinal bleeding. He was found to have pancreatic TB complicated by a duodenal ulcer with fistula. Following 1 month of antitubercular therapy, he experienced complete resolution of symptoms, healing of the duodenal ulcer, closure of the fistulous tract, and a decrease in the size of the pancreatic lesion as observed on imaging. Our case highlights the importance of early diagnosis and treatment of pancreatic TB.

Surgical correction of multiple renoduodenal fistulas due to chronic pyelonephritis: a case report and literature review.

Renoduodenal fistulas are a rare and uncommon phenomenon that account for ˂1% of those found between the urinary and intestinal tracts. Precipitation of this pathologic tract can be caused by chronic inflammation, necrosis, or ischemia. This case illustrates a 72-year-old man presenting with flank pain discovered to have multiple renoduodenal fistulas and our approach that led to the resolution of his symptoms. We review the pathophysiology, management, and effects of these fistulous tracts on renal function. Patients with staghorn calculi should undergo immediate evaluation for removal of the stone. In cases complicated by fistula formation, need for radical nephrectomy should be investigated and surgical repair should be pursued.

Laparoscopic Management of Cholecystoduodenal and Cholecystocolic Fistula: A Clinical Case Report.

Biliary fistula is a rare (less than 8%) cholecystectomy complication, internal fistulae being the most common of them (mainly colonic and duodenal). However, the presence of two fistulas at the same time is extremely rare, with a small number of cases reported in the literature to date. Symptoms tend to be non-specific, leading to a difficult preoperative diagnosis. The standard treatment for bilioenteric fistulas is open cholecystectomy and subsequent closure of the fistula. Nonetheless, modern techniques including laparoscopic and endoscopic approaches have been reported lately for their treatment with favorable results. We present a case of concomitant cholecystoduodenal and cholecystocolic fistula successfully treated with subtotal cholecystectomy and primary closure of the fistulous tracts by laparoscopic approach in a female Hispanic patient.

Signet Ring Cell Carcinoma Presenting as a Necrotic Duodenocolic Fistulizing Mass.

A 79-year-old female was referred for endoscopic evaluation after a positive fecal occult blood test. There was a long-standing history of iron deficiency anemia, weight loss with intermittent touts of intractable vomiting, and nausea. Esophagogastroduodenoscopy revealed a secondary lumen between the duodenum and transverse colon with necrotic mucosa and a blind opening. Subsequent colonoscopy revealed similar necrotic mucosa at the transverse colon and fistula formation with communication into the duodenum. Signet ring cell carcinoma (SRCC) was evident in histologic analysis. SRCC carries a poorer prognosis than other variants of colorectal carcinoma (CRC). Proposed mechanisms of increased mucin production can lead to mucosal wall destruction and have profound manifestations, such as in our patient with duodenocolic fistula.

A Case of Perforated Duodenal Diverticular Stone.

Nontraumatic surgical emergencies constitute a major bulk of general surgical practice. Most of the cases seen fall under routine, but now and then, a surgeon or emergency physician is faced with an unusual diagnosis or a rarer presentation of a usual diagnosis. Sharing among peers their experiences with these outliers of practice helps spread knowledge and increases the experience pool. We share our experience of a 66-year-old female who presented to our emergency with upper abdominal pain of one-day duration.

Successful endovascular treatment of superior mesenteric artery-duodenal fistula secondary to Rapunzel syndrome.

Rapunzel syndrome is a rare clinical entity in pediatric patients with a history of trichotillomania and trichophagia that has only been mentioned a few times in the literature. It is characterized by abnormal gastric bezoar formation that sometimes extends to the duodenum, jejunum, or colon. Here, we present a case of a 16-year-old previously healthy female patient who had prolonged hospitalization due to complications related to a significant gastric bezoar that led to massive bleeding due to a superior mesenteric artery (SMA)-duodenal fistula successfully treated with stent graft placement. Undiagnosed trichobezoar can lead to rare and unexpected complications, such as SMA-duodenal fistula, with life-threatening hemorrhagic shock. Prompt activation of massive transfusion protocol and endovascular control of the hemorrhage was vital to successfully treating our patient.

Complex duodenal fistulae: a surgical nightmare.

INTRODUCTION: A common feature of external duodenal fistulae is the devastating effect of the duodenal content rich in bile and pancreatic juice on nearby tissues with therapy-resistant local and systemic complications. This study analyzes the results of different management options with emphasis on successful fistula closure rates. METHODS: A retrospective single academic center study of adult patients treated for complex duodenal fistulas over a 17-year period with descriptive and univariate analyses was performed. RESULTS: Fifty patients were identified. First line treatment was surgical in 38 (76%) cases and consisted of resuture or resection with anastomosis combined with duodenal decompression and periduodenal drainage in 36 cases, rectus muscle patch, and surgical decompression with T-tube in one each. Fistula closure rate was 29/38 (76%). In 12 cases, the initial management was nonoperative with or without percutaneous drainage. The fistula was closed without surgery in 5/6 patients (1 patient died with persistent fistula). Among the remaining 6 patients eventually operated, fistula closure was achieved in 4 cases. There was no difference in successful fistula closure rates among initially operatively versus nonoperatively managed patients (29/38 vs. 9/12, p = 1.000). However, when considering eventually failed nonoperative management in 7/12 patients, there was a significant difference in the fistula closure rate (29/38 vs. 5/12, p = 0.036). The overall in-hospital mortality rate was 20/50 (40%). CONCLUSIONS: Surgical closure combined with duodenal decompression in complex duodenal leaks offers the best chance of successful outcome. In selected cases, nonoperative management can be tried, accepting that some patients may require surgery later.

Optimal surgical management of duodenal fistula in Crohn's disease: a Korean multicenter cohort study.

PURPOSE: Duodenal fistula in Crohn's disease (CDF) is a rare condition with an unclear optimal surgical management approach. We reviewed a Korean multicenter cohort of CDF surgery cases and assessed their perioperative outcomes to evaluate the effectiveness of the surgical interventions. METHODS: The medical records of patients who underwent CD surgery between January 2006 and December 2021 from three tertiary medical centers were retrospectively reviewed. Only CDF cases were included in this study. The demographic and preoperative characteristics, perioperative details, and postoperative outcomes were analyzed. RESULTS: Among the initial population of 2149 patients who underwent surgery for CD, 23 cases (1.1%) had a CDF operation. Fourteen of these patients (60.9%) had a history of previous abdominal surgery, and 7 had duodenal fistula at the previous anastomosis site. All duodenal fistulas were excised and primarily repaired via a resection of the originating adjacent bowel. Additional procedures such as gastrojejunostomy, pyloric exclusion, or T-tube insertion were performed in 8 patients (34.8%). Eleven patients (47.8%) experienced postoperative complications including for anastomosis leakages. Fistula recurrence was noted in 3 patients (13%) of which one patient required a re-operation. Biologics administration was associated with fewer adverse events by multivariable analysis (P = 0.026, odds ratio = 0.081). CONCLUSION: Optimal perioperative conditioning of patients receiving a primary repair of a fistula and resection of the original diseased bowel can successfully cure CDF. Along with primary repair of the duodenum, other complementary additional procedures should be considered for better postoperative outcomes.

Gallstone ileus: A case report and review of the literature.

INTRODUCTION AND IMPORTANCE: Gallstone ileus (GI) is defined as the occlusion of the intestinal lumen due to the impaction of one or more gallstones. The optimal management of GI is not consensual. We report a rare case of GI with a successful surgical treatment for a 65 year-old-female. CASE PRESENTATION: A 65 year-old-woman, presented with biliary colic pain and vomiting for three days. On examination, she had a distended tympanic abdomen. A computed tomography scan revealed signs of small bowel obstruction due to a jejunal gallstone. She had pneumobilia due to a cholecysto-duodenal fistula. We performed a midline laparotomy. We found a dilated and ischemic jejunum with false membranes regarding the migrated gallstone. We performed a jejunal resection with primary anastomosis. We performed cholecystectomy and closed the cholecysto-duodenal fistula at the same operative time. The postoperative course was uneventful. CLINICAL DISCUSSION: We reported successful surgical treatment for GI. It was a one-step procedure. GI is a rare situation. Due to their restricted lumen, the terminal ileum and the ileocaecal valve are where GI occurs most commonly. GI appears usually in elderly patients with comorbidities. The clinical presentation is not specific. CT scan evokes the diagnosis with high specificity. The surgical management of GI is not consensual. In our case, we performed bowel resection due to the presence of an ischemic intestine. CONCLUSION: GI is a rare situation. It appears usually in elderly patients with comorbidities. The clinical presentation is not specific. The surgical management of GI is not consensual.

It Is Not Always Diverticular Bleeding: Fatal Subtle Primary Aorto-Duodenal Fistula Associated With Abdominal Aortic Aneurysm.

Primary aorto-duodenal fistula (PADF) is a connection between the aorta and duodenum without prior aortic surgery. We present a case of an 80-year-old female who presented with hematochezia. She was vitally stable but later developed a large episode of hematemesis followed by cardiac arrest. A computed tomography angiogram (CTA) chest scan showed an abdominal aortic aneurysm (AAA) with no leakage or rupture. Esophagogastroduodenoscopy (EGD) demonstrated blood in the stomach and duodenum, but no source was identified. Tagged RBC scan showed massive hemorrhage in the stomach and proximal small bowel. Further review of the CT images identified a subtle PADF. The patient underwent endovascular aneurysm repair but died shortly after. Physicians should maintain a high awareness of PADF, particularly in elderly patients with obscure gastrointestinal bleeding with or without known AAA. Herald bleeding in the setting of an aortic aneurysm should raise suspicion for PADF even in the absence of extravasation on CTA.

Effect of postoperative utilization of somatostatin on clinical outcome after definitive surgery for duodenal fistula.

PURPOSE: To evaluate the effect of postoperative utilization of somatostatin after definitive surgery for duodenal fistula (DF) in preventing a recurrence. METHODS: Patients with definitive surgery for DF between January 2010 and December 2021 were categorized based on the utilization of somatostatin or not after the surgery. Patients in the Somatostatin group were matched to those in the Non-somatostatin group using propensity scores matching (PSM), so as to evaluate the effect of postoperative use of somatostatin by comparing the two groups. RESULTS: A total of 154 patients were divided into the in the Somatostatin group (84) and the Non-somatostatin group (70). Forty-three patients (27.9%) exhibited a recurrent fistula, with which the postoperative use of somatostatin was not associated (19 [22.6%] in the Somatostatin group and 24 (34.3%) in the Non-somatostatin group; unadjusted OR 0.56; 95% CI 0.28-1.14; P = 0.11). However, the postoperative usage of somatostatin served as a protective factor for developing into high-output recurrent fistula (eight (13.3%) in the Somatostatin group and 15 (25%) in the Non-somatostatin group; adjusted OR 0.39; 95% CI 0.15-0.93; P = 0.04). After PSM, the recurrent fistula occurred in 29.2% subjects (35/120). The postoperative usage of somatostatin was not associated with recurrent fistula (13 in PSM Somatostatin group vs. 22 in PSM Non-somatostatin group; unadjusted OR 0.48; 95% CI 0.21-1.07; P = 0.07), while its postoperative usage decreased the incidence of recurrent high-output fistula (5/60 in the PSM Somatostatin group, compared with 13/60 in the PSM Non-somatostatin group; adjusted OR 0.30; 95% CI 0.09-0.95). CONCLUSION: Postoperative use of somatostatin could effectively reduce the incidence of recurrent high-output fistula, without association with overall incidence of postoperative recurrent fistula.

Case report: Remedial surgical treatment of aorto-duodenal fistula with infected aneurysm after endovascular aortic repair.

Aorto-duodenal fistula (ADF) is a rare cause of upper gastrointestinal bleeding, but it is associated with high mortality. It usually occurs in patients with prior aortic surgery or who have undergone aortic graft placement. Abdominal aortic aneurysm (AAA) might be a cause of primary ADF, which could develop into sudden shock. Because ADF is difficult to diagnose, surgery to correct it has a poor outcome. We here report the successful treatment of an ADF complicated with infected AAA after endovascular repair of a ruptured aneurysm of the iliac artery.

Primary and secondary aorto-digestive fistulas in Behçet's disease: A case report and review of the literature.

Behçet's disease (BD) is a multisystem chronic autoimmune inflammatory disorder that involves multiple organs. Arterial involvements in BD are rare. One of severe manifestation is the aortic aneurysm which can lead to a rupture. Aorto-duodenal fistulas (ADFs) are the most frequent aorto-digestive fistulas. In this article we will describe and discuss primary and secondary ADFs which occurred in a same patient.

Mesenteric approach in pancreas-preserving partial duodenectomy for aortic graft-duodenal fistula: a case report.

An aortic graft-duodenal fistula commonly requires graft replacement and duodenectomy. However, the appropriate surgical approach to the duodenum with aortic graft fistula remains unclear. Herein, we describe the case of an 85-year-old male patient who underwent a pancreas-preserving partial duodenectomy using the mesenteric approach for aortic graft-duodenal fistula. The patient presented with hemorrhagic shock and duodenal bleeding 2 years after undergoing open aortic graft replacement. He first underwent emergent endovascular aortic repair with an artificial vascular graft to achieve hemostasis. Although his general condition stabilized following endovascular treatment, duodenal endoscopy revealed an aortic graft-duodenal fistula, exposing the artificial vascular graft via the third portion of the duodenum. As the radical treatment for aortic graft-duodenal fistula, open graft replacement and pancreas-preserving partial duodenectomy were performed using the mesenteric approach which helps to divide the pancreas and duodenum. The patient recovered without any major complications, such as postoperative pancreatic fistula, and was discharged. In conclusion, the mesenteric approach in partial duodenectomy for aortic graft-duodenal fistula could be safely performed. This procedure is useful to approach the duodenum fixed by fistula formation, which may help reduce intraoperative blood loss, operative time, and surgical invasiveness.
