Case report; effective community palliation of intractable malignant ascites with a permanently implanted abdominal drain

Symptomatic Fluid Drainage: Tunneled Peritoneal and Pleural Catheters

Malignant ascites and pleural effusion are significant contributors to patient symptoms such as shortness of breath, abdominal distension, and nausea in the setting of cancer. There are numerous methods employed to control such symptoms such as serial drainages, pleurodesis, and tunneled drainage catheters. Tunneled drainage catheters are a safe, effective, and a minimally invasive procedure to palliate the symptoms of malignant ascites and pleural effusion.

Management of non-ovarian cancer malignant ascites through indwelling catheter drainage

Backgrounds

Intra-abdominal placement of the Central Venous Catheter (CVC) was conducted to manage the ascites-related symptoms of non-ovarian cancer patients. The aim of this study is to document the efficacy of symptom relief and conduct survival analysis of non-ovarian cancer patients with malignant ascites who received paracentesis and indwelling catheter drainage.

Methods

Seventy eight patients received paracentesis and drainage. All patients who met the inclusion criteria were included in this study. The overall survival (OS) was defined as the interval between initial diagnosis and death. Since-paracentesis survival (SP-Survival) was defined as the interval between initial paracentesis and death.

Results

Hepatic cancer was the most frequent original cancer in this study. Peritoneal catheters remained in situ for a median of 13 days. No immediate complications, such as perforation of a viscus or excessive bleeding, were encountered during placement. All ascites-related symptoms improved after drainage compared with the baseline. There was a statistically significant improvement in the mean score for abdominal swelling (p < 0.001), anorexia (p = 0.023) and constipation (p = 0.045). Cancer type was shown to be an independent prognostic factor for overall survival length (p = 0.001). Serum albumin was an independent prognostic factor for SP-survival (p = 0.02).

Conclusions

Paracentesis and indwelling catheter drainage through CVC set is a useful method for improving painful symptom. Further research is needed to validate the findings.

Peritoneal catheter for continuous drainage of ascites in advanced cancer patients

INTRODUCTION

Advanced cancer patients with refractory ascites do not often respond to dietary sodium restriction and diuretics. While paracentesis is effective, the condition invariably recurs, necessitating repeated procedures. A continuous peritoneal drainage by an indwelling catheter has been reported to be hugely beneficial symptomatically, avoiding the hazards and disadvantages of multiple repeated procedures and direct and indirect costs.

MATERIALS AND METHODS

Forty patients with advanced cancer patients admitted to an acute pain relief and palliative care unit, who presented symptomatic ascites, were recruited for continuous drainage of peritoneal fluid. A central venous catheter set for Seldinger technique was used. Technical failure was defined as an unsuccessful drainage of fluid through the catheter. Immediate and late complications, including hypotension, haemorrhage, tube blockage, dislodgment and sepsis were recorded. Record of daily drainage during admission were noted. At time of discharge, patients were asked to rate their global symptom burden as improved, unchanged or worsened. The follow-up was performed with frequent phone contacts or day-hospital admission in case of problems.

RESULTS

The mean patients' age was 68 years, and 21 were men. Patients were receiving unsuccessfully a mean dose of furosemide of 32 mg/day. The technique was not painful and was easily accepted by patients. Insertion was technically successful in almost all patients. Mean admission time was 5.5 days (range 2-14), and the mean drained volume during admission was 8,499 ml (range 800-20,700), 2,850 ml (300-4,200) being drained on the first 24 h. No immediate complications were recorded. Six patients died during admission. The mean survival was 38.9 days (range 1-120). Of the 34 patients who were discharged home, 22 patients stated that symptom burden had improved, while in 10 patients symptom burden did not change or worsened, probably due to the advanced status of diseases and multiple contributing factors. Five, two, and one patients required skin sutures at 1, 2 and 3 months, respectively. About one third of patients had mechanical problems, some of them requiring a catheter replacement. No infection was recorded.

CONCLUSION

In conclusion, a permanent peritoneal catheter was a valuable method to remove abdominal fluids and reduce symptom burden attributable to ascites and was also easy to use at home. Complication rate was acceptable and balanced by the benefits of the technique which avoided frequent paracentesis and associated complications.
