Perioperative management of continuous ambulatory peritoneal dialysis patients undergoing inguinal hernia surgery.

Management of patients undergoing dialysis after inguinal hernia surgery has not been standardized. This report presents the results of 9 patients with inguinal hernias (11 hernias) who were undergoing continuous ambulatory peritoneal dialysis (CAPD). All patients treated in this hospital since 2007 have returned to CAPD within 3 days after surgery without switching to hemodialysis (HD). The mean durations for resuming CAPD after surgery were 7.6 days from 1998 through 2007 and 2.3 days since 2008. The surgical procedure was performed with a polypropylene mesh in all cases. Local anesthesia was utilized for one patient with low cardiac function. All patients recovered rapidly, with no uremia or dialysis-related complications. No leakage or hernia recurrence was observed over the subsequent observation period (56.2 months). This experience suggests the possibility that interim HD can therefore be skipped in patients undergoing CAPD if the hernia sacs are closed tightly. Local anesthesia seems to be safe for high-risk hernia patients undergoing CAPD.

Surgical resection of pulmonary metastases from colorectal cancer: Four favourable prognostic factors.

BACKGROUND: Surgical resection has been the first choice for treatment of pulmonary metastases from colorectal cancer; however, indications for surgery have yet to be adequately clarified. In considering strategies for the treatment of pulmonary metastases from colorectal carcinoma, determination of disease status as either systemic or pre-systemic is of primary importance. The aim of this study is to define the characteristics of those patients who are most likely to benefit from surgical resection. METHODS: Fifty-eight patients who underwent pulmonary resection for colorectal metastases were retrospectively reviewed and examined for clinicopathological factors. RESULTS: Overall, 5-year survival rates were 29%, with a median survival time (MST) of 27 months. Multivariate analysis identified four factors that indicate independent and favourable prognostic impact: three or less tumours, metachronous metastasis, negative hilar and/or mediastinal lymph node metastasis and normal prethoracotomy serum carcinoembryonic antigen level. The 5-year survival rate for 16 patients who satisfied all of these favourable characteristics was 62% (MST = 86 months), which was significantly better than those patients lacking these characteristics. The 5-year survival rate for 13 patients who underwent repeated metastasectomy was 37% (MST = 32 months). CONCLUSIONS: The four factors selected in our multivariate analysis appear to be favourable factors for the practical identification of those patients who are most likely to benefit from surgical resection. Repeated pulmonary resection for lung-only recurrence may benefit carefully selected patients.
