Preoperative Wilms tumor rupture

CANCER, Issue 1 2008
A retrospective study of 57 patients
Abstract BACKGROUND. According to current International Society of Pediatric Oncology (SIOP) Wilms recommendations, all preoperative tumor ruptures should be classified as stage IIIc. However, to the authors' knowledge, the definition and diagnostic criteria of preoperative rupture have not been defined clearly. METHODS. The authors performed a retrospective analysis of 57 children with clinical and/or radiologic (computed tomography [CT]) signs of preoperative tumor rupture of a series of 250 patients enrolled in Wilms SIOP protocols at their institution. RESULTS. Clinical and radiologic signs of preoperative rupture were observed in 39 patients and 55 patients, respectively. The site of rupture on imaging was retroperitoneal only in 48 patients and both retroperitoneal and intraperitoneal in 7 patients. Surgery was performed after chemotherapy in 55 of 57 patients. Peritoneal disease recurrence occurred in 3 of 57 patients, including 2 patients with stage III tumors who had initial intraperitoneal rupture and 1 patient with a stage I tumor. Among the 48 patients who had radiologic signs of retroperitoneal-only rupture, the final pathologic stage was stage III in 22 patients, stage II in 9 patients, and stage I in 17 patients, and no abdominal disease recurrence was observed, although only 23 of 48 patients received flank radiotherapy. The 5-year local control rate was significantly higher in patients who had retroperitoneal-only rupture compared with patients who had intraperitoneal rupture (100% vs 83.3%; standard error, ±15.2%; P = .0015). CONCLUSIONS. The use of CT scans significantly increased the number of patients who could be classified with "tumor rupture." Intraperitoneal rupture was diagnosed accurately with CT and was associated with a significant risk of peritoneal disease recurrence. In contrast, patients who have radiologic signs of localized retroperitoneal-only rupture at diagnosis most likely should not be upstaged, and their treatment may be determined according to pathologic stage only.

Hepatectomy for pyogenic liver abscess

HPB, Issue 2 2003
RW Strong
Background Commensurate with the advances in diagnostic and therapeutic radiology in the past two decades, percutaneous needle aspiration and catheter drainage have replaced open operation as the first choice of treatment for both single and multiple pyogenic liver abscesses. There has been little written on the place of surgical resection in the treatment of pyogenic liver abscess due to underlying hepatobiliary pathology or after failure of non-operative management. Methods The medical records of patients who underwent resection for pyogenic liver abscess over a 15-year period were retrospectively reviewed. The demographics, time from onset of symptoms to medical treatment and operation, site of abscess, organisms cultured, aetiology, reason for operation, type of resection and outcome were analysed. There were 49 patients in whom the abscesses were either single (19), single but multiloculated (11) or multiple (19). The median time from onset of symptoms to medical treatment was 21 days and from treatment to operation was 12 days. The indications for operation were underlying hepatobiliary pathology in 20% and failed non-operative treatment in 76%. Two patients presented with peritonitis from a ruptured abscess. Results The resections performed were anatomic (44) and non-anatomic (5). No patient suffered a recurrent abscess or required surgical or radiological intervention for any abdominal collection. Antibiotics were ceased within 5 days of operation in all but one patient. The median postoperative stay was 10 days. There were two deaths (4%), both following rupture of the abscess. Discussion Except for an initial presentation with intraperitoneal rupture and, possibly, cases of hepatobiliary pathology causing multiple abscesses above an obstructed duct system that cannot be negotiated non-operatively, primary surgical treatment of pyogenic liver abscess is not indicated. Non-operative management with antibiotics and percutaneous aspiration/drainage will be successful in most patients. If non-operative treatment fails, different physical characteristics of the abscesses are likely to be present and partial hepatectomy of the involved portion of liver is good treatment when performed by an experienced surgeon.
