Gastropleural fistula from gastric perforation due to renal cell carcinoma after bevacizumab chemotherapy: a case report

A noninvasive treatment for gastro-mediastinal or gastro-pleural fistula after esophagogastrectomy

Our objective was to assess the safety and efficacy of 3 tubes with or without covered esophageal stent placement for the management of gastro-mediastinal or gastro-pleural fistula. We retrospectively assessed the clinical data of 31 consecutive patients with gastro-mediastinal or gastro-pleural fistula treated by using a noninvasive treatment from February 2013 to July 2022. Patients received 3 tubes (jejunal feeding tube, gastrointestinal drainage tube and abscess drainage tube) with or without esophageal-covered stent placement. All patients received continue abscess drainage and nutritional support after procedure. The tubes and/or esophageal-covered stents were removed after fistula healing. All patients received 3 tubes placement and 11 patients with luminal narrowing received esophageal covered stent placement. Technically success was found in all patients, with no procedure-related death, esophageal rupture or massive hemorrhage. Abscess cavity disappeared in 22 patients, with a clinical success rate of 71.0%. All patients received esophageal stent placement were cured and stents were removed, for a median duration of 1.6 months (interquartile ranges [IQR] 1.4, 3.7). Three patients showed clinical improved, with markedly decreased abscess cavity and markedly shrunk fistula. The median survival was 30.8 months. The 1-, 3-, 5-year survival rates were 71.1%, 46.1% and 39.5%, respectively. A noninvasive treatment of 3 tubes with or without covered esophageal stent placement is safe and effective for gastro-mediastinal or gastro-pleural fistula after esophagogastrectomy.

Rare case of high amylase pleural effusion without pancreatitis, oesophageal rupture or malignancy

High amylase pleural effusion remains an entity which includes a wide variety of differentials, with pancreatitis, oesophageal rupture or malignant pleural effusion being most commonly encountered in clinical practice. Keeping the clinical picture (suggestive of pain in abdomen preceding any respiratory complaints) and differentials at hand, the case was evaluated with contrast-enhanced CT of the thorax and abdomen which revealed normal pancreatic architecture and no abnormal communication was noted between the pancreas and pleural space. A contrast oesophagogram, done when pancreatitis was ruled out, showed no evidence of any leak. The patient underwent upper gastrointestinal endoscopy which was suggestive of an ulcer with fistulous communication with the pleural space. Following nasojejunal feeding and clipping of the fistulous tract the patient's symptoms improved.

Gastropleural fistula masquerading as chylothorax in a child with lymphoma

We report the case of an 8-year-old boy with diffuse large B cell lymphoma who developed a right-sided spontaneous pneumothorax with pleural effusion after recovery from septic shock. The pleural fluid was thought to be malignancy-associated chylothorax concomitant with complicated pleural effusion due to a milky-like appearance, a high level of triglycerides and Gram-negative bacteria staining in the fluid. He was put on total parental nutrition and octreotide for 2 weeks, but did not improve. The laboratory results also showed a persistent bacterial infection in the pleural fluid despite appropriate antibiotics. Eventually, a CT scan revealed a fistulous tract between the right pleural cavity and the stomach. Fistula repair was successful by right open thoracotomy with decortication. Even though the gastropleural fistula is a very rare condition in paediatric patients, the physician should consider this diagnosis in a patient who has an unusual presentation or refractory chylothorax-like pleural effusion.

Markedly higher sFlt-1/PlGF ratio in a woman with acute fatty liver of pregnancy compared with HELLP syndrome

AIM

To compare serum levels of angiogenesis-related factors between 14 women with HELLP (hemolysis, elevated liver enzymes and low platelet count) syndrome and a woman with acute fatty liver of pregnancy (AFLP).

METHODS

Serum samples were collected in 2004-2008 and 2013-2016. The levels of soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF) were measured by an automated electrochemiluminescence immunoassay using Elecsys sFlt-1 and Elecsys PlGF. After logarithmic transformation, levels of sFlt-1, PlGF and the sFlt-1/PlGF ratio in a woman with AFLP were compared with those in women with HELLP syndrome, using the one-sample t-test.

RESULTS

At 37 weeks of gestation, a patient was diagnosed with AFLP based on Swansea criteria (showing six features including elevated transaminases), and she also showed a duodenal ulcer with active bleeding, thrombocytopenia and hypertension. Her serum levels of sFlt-1 and sFlt-1/PlGF ratio were significantly higher than in those with HELLP syndrome (273 040 pg/mL vs 15 135 [mean], P < 0.001; 4236 vs 224, P < 0.001; respectively). However, her serum level of PlGF was not significantly different from those with HELLP syndrome.

CONCLUSION

Serum levels of sFlt-1 and the sFlt-1/PlGF ratio, but not PlGF, in a woman with AFLP were markedly higher than those in women with HELLP syndrome. AFLP may be a different clinical entity from HELLP syndrome based on angiogenesis-related factors. Clinically, the sFlt-1/PlGF ratio may be used to rapidly distinguish AFLP from HELLP syndrome.

Laparoscopic Gastropleural Fistula Repair: A Minimally Invasive Solution for a Complex Problem

INTRODUCTION

Gastropleural fistula (GPF) is a complex pathology that can present as a result of surgery, trauma, peptic ulcer disease, malignancies, radiation, or chemotherapy. Management typically includes endoscopic or surgical intervention along with intraabdominal or intrathoracic drainage of pre-existing infection. Traditionally, surgical approaches have been through exploratory laparotomy or thoracotomy, subjecting already ill patients to additional morbidity.

CASE REPORT

We describe and demonstrate a laparoscopic minimally invasive approach to the management of a GPF with a wedge resection of the stomach, along with a review of the current literature regarding GPF treatment.

CONCLUSION

GPF repair can be performed through laparoscopy and may lead to improved patient outcomes and faster recovery.

Gastropleural fistula in metastatic ovarian cancer

Gastropleural fistula is a rare condition, most frequently reported as a result of trauma, peptic ulcer disease or malignancy. We report a case of gastropleural fistula in a patient with metastatic ovarian cancer who presented with hydropneumothorax and mediastinal shift. She was successfully managed with an open partial gastrectomy, repair of diaphragmatic defect, and thoracoscopic washout and decortication. Based on our case and review of the literature, surgical repair of gastropleural fistula should be considered as a palliative procedure even in patients with end-stage cancer.

Incidence and management of gastrointestinal perforation from bevacizumab in advanced cancers

Bevacizumab (Avastin™, Genentech) is a monoclonal antibody that deactivates the vascular endothelial growth factor leading to disruption of vital cancer signaling pathways and inhibition of angiogenesis which results in its anti-tumor activity. The use of bevacizumab in treating cancers has steadily increased since it was initially approved by the Food and Drug Administration for metastatic colorectal cancer. Clinical trials have revealed that bevacizumab has serious side effects, including spontaneous bowel perforation, which can occur in patients who have no involvement of the gastrointestinal tract by cancer. Although risk factors for bevacizumab-associated bowel perforation have been identified, it is still unclear which patients are specifically at risk for this complication. The management of bevacizumab-induced bowel perforation depends on the clinical presentation and the goals of care set by the treating physicians and the patient.
