Endoscopic management of postcholecystectomy complications at a Nigerian tertiary health facility.

BACKGROUND: Cholecystectomy and common bile duct exploration for biliary stone disease are common hepatobiliary surgeries performed by general surgeons in Nigeria. These procedures can be complicated by injury to the biliary tree or retained stones, requiring repeat surgical intervention. This study presents the experience of using endoscopic retrograde cholangiopancreatography (ERCP) in the management of hepatobiliary surgery complications at the academic referral center of Obafemi Awolowo University Teaching Hospital (OAUTHC) Ile-Ife, Nigeria. METHODS: All patients with postcholecystectomy complications referred to the endoscopy unit at OAUTHC from March 2018 to April 2023 were enrolled. Preoperative imaging included a combination of abdominal ultrasound, CT, MRI, magnetic resonance cholangiopancreatography (MRCP), and T-tube cholangiogram. All ERCP procedures were performed under general anesthesia. RESULTS: Seventy-two ERCP procedures were performed on 45 patients referred for postcholecystectomy complications. The most common mode of presentation was ascending cholangitis [16 (35.6%)], followed by persistent biliary fistula [12 (26.7%)]. The overall median duration of symptoms after cholecystectomy was 20 weeks, with a range of 1-162 weeks. The most common postcholecystectomy complication observed was retained stone [16 (35.6%)]. Other postcholecystectomy complications included bile leakage, bile stricture, bile leakage with stricture, and persistent bile leakage from the T-tube in 12 (26.7%), 11 (24.4%), 4 (8.9%), and 2 (4.4%) patients, respectively. Ampullary cannulation during ERCP was successful in all patients (45, 100%). Patients with complete biliary stricture (10/12) required hepaticojejunostomy. CONCLUSION: Endoscopic management of postcholecystectomy complications was found to be safe and reduce the number of needless surgeries to which such patients are exposed. We recommended prompt referral of such patients for ERCP.

Cholecystopleural fistula: A case report and literature review.

INTRODUCTION: Gallstone with acute cholecystitis is one of the most common diseases in the clinic. If the disease is serious, gallbladder gangrene, perforation, and sepsis may be caused. Gallbladder diseases rarely cause thoracic-related complications, especially pleural fistula, which is very rare in clinical practice. PATIENT CONCERNS: A 52-year-old male patient was admitted to the emergency department for 1 month with recurrent right middle and upper abdominal pain. DIAGNOSIS: Computed tomography diagnosis: cholecystitis and peri-inflammation, small abscess around the base of the gallbladder, local peritonitis, and bilateral pleural effusion. INTERVENTIONS: After admission, conservative treatment was given. On the 4th day of admission, the symptoms worsened, and an emergency catheter drainage was performed on the right thoracic cavity to extract 900 mL of dark yellow effusion. After the operation, a large amount of bili-like fluid was continuously drained from the thoracic drainage tube. After the iatrogenic biliary fistula caused by thoracic puncture was excluded, cholecystopleural fistula was considered to be cholecystopleural fistula. On the 6th day of admission, endoscopic retrograde cholangiopancreatography (ERCP) + cholecystography + Oddi sphincterotomy + laminating biliary stent was performed in the emergency department, and cholecystopleural fistula was confirmed during the operation. OUTCOMES: The patient recovered well after surgery, computed tomography examination on the 20th day after surgery indicated that pleural effusion was significantly reduced, and the patient was cured and discharged. The patient returned to the hospital 8 months after the ERCP operation to pull out the bile duct-covered stent. The patient did not complain of any discomfort after the postoperative follow-up for 3 years, and no recurrence of stones, empyema, and other conditions was found. CONCLUSION: Cholecystopleural fistula is one of the serious complications of acute cholecystitis, which is easy to misdiagnose clinically. If the gallbladder inflammation is severe, accompanied by pleural effusion, the pleural effusion is bili-like liquid, or the content of bilirubin is abnormally elevated, the existence of the disease should be considered. Once the diagnosis is clear, active surgical intervention is needed to reduce the occurrence of complications. Endoscopic therapy (ERCP) can be used as both a diagnostic method and an important minimally invasive treatment.

Cholecystoappendiceal fistula associated with xanthogranulomatous cholecystitis.

Xanthogranulomatous cholecystitis is a rare chronic inflammatory disease of the gallbladder associated with complications such as perforation, dense adhesions and fistulation. We present a case of a female patient in her 20s who presented with three episodes of recurrent cholecystitis over 3 months. Her medical history included an endoscopic retrograde cholangiopancreatography for obstructive jaundice due to choledocholithiasis. As there was no possibility of performing an urgent cholecystectomy during her initial admission, she was listed for an elective operation. Laparoscopic inspection revealed a pericholecystic mass involving the omentum, transverse colon, duodenum and liver and findings suspicious of a cholecystoappendiceal fistula. Laparoscopic cholecystectomy and appendicectomy were performed. Early index admission laparoscopic cholecystectomy should be performed in patients with acute cholecystitis to prevent higher grades of operative difficulty and associated complications. This case presentation-cholecystoappendiceal fistula associated with xanthogranulomatous cholecystitis-emphasises the necessity of complying with national guidelines in managing acute calculous cholecystitis.

Complicated Liver Cystic Echinococcosis-A Comprehensive Literature Review and a Tale of Two Extreme Cases.

Cystic echinococcosis is a zoonotic parasitic disease that affects the liver in more than 70% of cases, and there is still an underestimated incidence in endemic areas. With a peculiar clinical presentation that ranges from paucisymptomatic illness to severe and possibly fatal complications, quality imaging and serological studies are required for diagnosis. The mainstay of treatment to date is surgery combined with antiparasitic agents. The surgical armamentarium consists of open and laparoscopic procedures for selected cases with growing confidence in parenchyma-sparing interventions. Endoscopic retrograde cholangiopancreatography (ERCP) is extremely useful for the diagnosis and treatment of biliary fistulas. Recent relevant studies in the literature are reviewed, and two complex cases are presented. The first patient underwent open surgery to treat 11 liver cysts, and during the follow-up, a right pulmonary cyst was diagnosed that was treated by minimally invasive surgery. The second case is represented by the peritoneal rupture of a giant liver cyst in a young woman who underwent laparoscopic surgery. Both patients developed biliary fistulas that were managed by ERCP. Both patients exhibited a non-specific clinical presentation and underwent several surgical procedures combined with antiparasitic agents, highlighting the necessity of customized treatment in order to decrease complications and successfully cure the disease.

Broncho biliary fistula following interventional radiology for hepatic metastases.

Bronchobiliary fistulas are defined as an abnormal communication between the biliary system and the bronchial tree. They are extremely rare complications of radiofrequency or microwave ablation. A 39-year-old woman with a history of neuroendocrine pancreatic carcinoma suffering from liver metastasis was treated with microwave ablation (MWA). In this case report, we present a case of intractable biliptysis from a bronchobiliary fistula secondary to an MWA. The patient was diagnosed by endoscopic retrograde cholangiopancreatograph and hepatobiliary scintigraphy. Treatment involved a right hemihepatectomy, a redo-hepaticojejunostomy, and the surgical placement of a transhepatic drain. After 6 weeks of drain placement, this could be removed. The fistula was thus successfully treated.

A Novel Technique for the Management of Persistent Biliary Fistulas Developing After Liver Hydatid Cyst Surgeries: Drain Clamping Technique.

BACKGROUND: External biliary fistula, where the residual cyst is associated with the biliary tree, is one of the most common complications after liver hydatid cyst surgery. Surgical procedures become a consideration for patients in whom the biliary fistula persists despite all endoscopic procedures. However, reoperation for biliary fistula after hydatid cyst surgery leads to additional complications and increases morbidity and mortality. AIM: This study aims to treat persistent biliary fistulas that develop after liver hydatid cyst surgery using a simple noninvasive technique. MATERIALS AND METHODS: External drainage surgery was performed on 295 patients with liver hydatid cysts. Endoscopic treatment methods were used in patients who developed biliary fistula after surgery. Despite all endoscopic treatment methods, 14 patients developed persistent biliary fistulas. These patients were subsequently treated using the drain clamping technique. FINDINGS: All persistent fistulas occluded in 11.86 days (with a range of 8-20 days). No complications were observed in the one-year follow-up visits. CONCLUSION: Drain clamping, a novel approach to the treatment of persistent biliary fistulas developed despite all available endoscopic methods, can be safely used. This technique resulted in a complete recovery in patients without the need for surgical procedures.

Traumatic biliary fistula with bile duct disconnection.

A 43-year-old man was admitted to our department for accident. Computed tomography (CT) scan revealed low-density shadows in the hepatogastric and peripancreatic space. The patient still has abdominal pain after the performation of CT-guided abdominal puncture and drainage. Magnetic Resonance Cholangiopancreatography (MRCP) showed that the middle and lower segments of common bile duct were stricture and truncature. Endoscopic bile duct catheterization and drainage showed that the lower segment was dislocated and disconnected. Then the doctor used the balloon and contrast agent to pressurize, and at the same time, the distal common bile duct was pulled by the mirror, trying to straighten the common bile duct, changing its axial direction, and try to bridge it repeatedly by using the guide wire of misgurnus anguillicaudatus. The patient significantly improved over the next 3 days. After 11 months of follow-up, the patient came to our hospital to remove the biliary stent,and has no abdominal pain anymore.

Bronchobiliary fistula caused after percutaneous transhepatic biliary drainage treatment: A case report.

RATIONALE: Percutaneous transhepatic biliary drainage (PTBD) plays a significant role especially in the diagnosis and decompression of bile duct obstruction. However, it is associated with complications such as hemobilia, occlusion of drainage, bile leakage, and even bronchobiliary fistula (BBF). PATIENT CONCERNS AND DIAGNOSES: We herein describe a patient with a complication of BBF caused by long-term indwelling PTBD catheters. She underwent multiple operations including bilioenteric anastomosis, hepatic left lateral lobectomy, and long-term PTBD treatment. Her symptoms were mainly cough, fever, and yellow sputum and her diagnosis was confirmed by sputum culture (bilirubin detection was positive). INTERVENTIONS AND OUTCOMES: The patient recovered uneventfully by minimally invasive treatment, was discharged after 1 week of hospitalization, and the drainage tube was removed 2 weeks later. During 2 years of follow-up, no recurrence of BBF was observed. LESSONS: Patients with long-term indwelling PTBD catheters for biliary tract obstruction may lead to BBF. The treatment plan of BBF is tailored to the patient's individualized characteristics. And minimally invasive treatments might be an effective alternate way for the treatment of BBF. The accurate diagnosis, precision treatment, and multidisciplinary team play important roles in the treatment of BBF.

[Spontaneous cholecysto-cutaneous fistula: about two cases]. / Fístula colecisto-cutánea espontánea: a propósito de dos casos.

Cholecysto-cutaneous fistula (CCF) is a rare complication of untreated biliary pathology, with fewer than 100 cases documented in the literature. Most are secondary to bacterial infection, although it has also been described in gallbladder adenocarcinoma and post trauma. Its clinical presentation is variable, being able to present systemic affection, and its most frequent external drainage site is in the right hypochondrium. Due to the low incidence of this pathology, and the variety of forms of presentation, its management does not have, to date, standardized bases. We present two cases of patients who consulted in the emergency room at the Hospital Nacional de Clínicas for presenting cholecysto-cutaneous fistula. The treatment of both was surgical.

La fístula colecisto-cutáneas (FCC) es una rara complicación de la patología biliar no tratada, habiendo menos de 100 casos documentados en la literatura. La mayoría son secundarias a infección bacteriana, aunque también fue descripta en el adenocarcinoma de vesícula y posterior a traumatismo. Su presentación clínica es variable, pudiendo presentar afección sistémica, y su sitio más frecuente de drenaje externo es en hipocondrio derecho. Debido a la baja incidencia de esta afección, y a la variedad de formas de presentación, su manejo no tiene hasta el momento bases estandarizadas. Presentamos dos casos de pacientes que consultaron por guardia de urgencias en el Hospital Nacional de Clínicas por presentar fistula colecisto-cutánea. El tratamiento de ambos fue quirúrgico.

[Hemobilia as a sign of arterio-biliary fistula]. / Gemobiliya kak proyavlenie arteriobiliarnoi fistuly.

Hepatic artery aneurysms (HAA) are rare (20% of all visceral arteries). Most often, HAAs are asymptomatic and detected at autopsy. However, their ruptures and/or bleeding following pressure ulcers in visceral gastrointestinal organs are a significant clinical and diagnostic problem. We present 2 patients with obstructive jaundice and hemobilia. Diagnostics revealed aneurysm of the right hepatic artery with arterio-biliary fistula. Life-threatening hemobilia is a consequence of HAA rupture into biliary system. Endovascular approach is preferable for HAA without clinical manifestations. Awareness of this disease is important for early detection and active surgical intervention before possible complications.

Risk factors and management of biliary leakage after Endocystectomy for hepatic cystic echinococcosis.

BACKGROUND: Endocystectomy is a conservative surgical approach to managing cystic echinococcosis. Bile leakage is the main complication of this technique. The aim of this study was to evaluate the factors associated with bile leakage and to assess the outcomes and cost efficiency of strategies used to treat bile leakage. METHODOLOGY/PRINCIPAL FINDINGS: Patients who underwent endocystectomy between 2005 and 2020 were included. The preoperative characteristics, intra- and postoperative outcomes, hospital costs, and cost efficiency (the Diagnosis-Related Group reimbursement minus the overall cost) were evaluated prospectively. A total of eighty patients with 142 cysts were included. Postoperative complications occurred in 17 patients (21%), including 11 patients with bile leakage (type A: 1, type B: 6 and type C: 4 patients, total 13%). Bile leakage was more frequent in patients with preoperative MRI signs of cysto-biliary fistulas or intraoperative visible cysto-biliary fistulas (p = 0.03 and p = 0.04, respectively) and in patients with cysts larger than 8 cm (p = 0.03). Patients with bile leakage who underwent reoperation (type C) had significantly shorter hospital stays (9 vs. 16 days, p<0.01) and better cost efficiency than those who received radiologic or endocscopic interventions (€2,072 vs. -€2,097 p = 0.01). No mortality was observed, and recurrence was seen in two patients. CONCLUSIONS/SIGNIFICANCE: Endocystectomy is a safe and efficient technique. Preoperative and intraoperative cysto-biliary fistulas and a cyst diameter larger than 8 cm are correlated to postoperative bile leakage. Early operative management of bile leakage reduces hospital stay and improves cost efficiency compared with radiologic or endoscopic treatments.
