Summary

Primary Aims: To compare the performance of pigtail catheter to that of ICT in drainage of pleural effusion of medical aetiology regarding: 1. Various complications(mainly wound pain) that result from either therapeutic approach. 2. Success of complete drainage. 3. Compare the duration needed for complete drainage. Secondary Aims: To evaluate both techniques in terms of: 1. Degree of patient's mobility that either technique permits. 2. Percentage of patients that can be managed on outpatient settings by either approach

Detailed description

The pleural cavity is a space between the visceral and parietal pleura that contains a subtle amount of serous fluid (10 to 20ml) this fluid act as a lubricant to the pleural surface for proper gliding during respiration . Accumulation of abnormal amount of pleural fluid occurs under various pathological disorders, each of which manifests with a different physical and biochemical characteristics of the effused pleural fluid, it may be serous,pus,blood,or chyle. Long standing undrained accumulated pleural fluid can lead to serious complications: like lung collapse leading to respiratory failure, fibrosis or scarring of the pleural membranes and underlying lung tissue, empyema, septic shock and even death in severe circumstance . So we always seek to drain accumulated pleural fluid; Chest tubes connected to underwater seal have largely replaced open thoracotomy and rib resection in draining exudative pleural effusion and are now considered the standard method . However Intercostal tube drainage poses risks and hazards: large size of the tube that make it more painful more tissue destructive with more injury to intercostal arteries and nerves, the incisional insertion is also painful and results in more tissue dissection, moreover the tube is heavy as it need water seal to work so causing patient discomfort and increase liability of slippage. Recently pigtail catheter has been employed to drain accumulated pleural fluid .pigtail catheter has many advantages: it has small caliber , which makes it less painful, less tissue destruction, less Injurious to intercostal nerves and vessels, Additionally it has a suction power with unidirectional valve which abolishes the need for underwater seal; thus avoiding the heavy weight of bottles and decreasing the risk of accidental slippage, inserted with trocar under ultrasonographic guidance decreasing liability of lung injury. Previous studies compared pigtail versus chest tube in drainage of pleural effusion show .A total of 92 patients were included in the study, 57 (61.9%) patients in pigtail group and 35 (31.8%) in ICD group. Causes of pleural effusion included were pneumonia, malignancy,TB. the study had revealed that pigtail catheter had higher success rate less painful with no significant difference at mean duration of drainage..At other study data collected retrospectively from 60 patient aged more than 18 year 30 patients had an intercostal chest tube and 30 patients had pigtail catheters found that no statistically significant difference between pigtail and ICT at success rate and duration of drainage but pigtail found less painful with less incidence of complication regarding pneumothorax and catheter kinking and slippage . However these studies have some limations first study was observational study not randomised, second study was retrospective with small sample size. Both studies have no clear definitions of outcomes , not focus on complications mainly wound pain as primary outcome and didn't answer the question of recurrence or drainage failure of pleural effusion after pigtail catheter drainage.
