Purpose: The procedure for prolapse and hemorrhoids (PPH) has the advantage of less postoperative pain. However, serious postoperative complications have been reported after PPH, and the postoperative recurrence rate is high in comparison with conventional Milligan-Morgan hemorrhoidectomy (MMH). The purpose of this study was to evaluate PPH with low rectal anastomosis (PPH-LA) in comparison with the original PPH and MMH. Methods: Among a total of 1315 patients with hemorrhoids, MMH was conducted in 322, original PPH using a PPH 01 stapler (PPH01) in 63, PPH-LA using 01 (PPH-LA01) in 236, 03 (PPH-LA03) in 649, and sclerotherapy (SCL) in 45. Results: Length of hospital stay and number of working days lost were significantly greater for MMH than for any form of PPH. The rate of massive postoperative bleeding was significantly lower after PPH-LA03 than after PPH01 or PPH-LA01. No serious postoperative complications occurred after any form of PPH. A significantly higher proportion of patients complained of continued prolapse after PPH01 than after MMH, PPH-LA01, or -LA03. The 5- and 16-year postoperative cumulative recurrence rates after PPH-LA03 were significantly lower than after PPH01. Conclusions: The postoperative cumulative recurrence rate after PPH-LA03 is as low as that after MMH for up to 16 years, and compared with the original PPH01, the effectiveness is higher and the postoperative cumulative recurrence rate for up to 16 years is significantly lower. We conclude that PPH-LA03 is a superior procedure for hemorrhoids, having less postoperative pain and a low rate of recurrence. [ABSTRACT FROM AUTHOR]

Purpose: Hospital factors along with various patient and surgeon factors are considered to affect the prognosis of colorectal cancer. Hospital volume is well known, but little is known regarding other hospital factors. Methods: We reviewed data on 853 patients with stage IV colorectal cancer who underwent elective palliative primary tumor resection between January 2006 and December 2007. To detect the hospital factors that could influence the prognosis of incurable colorectal cancer, the relationships between patient/hospital factors and overall survival were analyzed. Among hospital factors, hospital type (Group A: university hospital or cancer center; Group B: community hospital), hospital volume, and number of colorectal surgeons were examined. Results: In univariate analysis, Group A hospitals showed significantly better prognosis than Group B hospitals ( p = 0.034), while hospital volume and number of colorectal surgeons were not associated with overall survival. After adjustment for patient factors in multivariate analysis, hospital type was significantly associated with overall survival (hazard ratio: 1.31; 95 % confidence interval: 1.05-1.63; p = 0.016). However, there was no significant difference in short-term outcomes between hospital types. Conclusions: Hospital type was identified as a hospital factor that possibly affects the prognosis of stage IV colorectal cancer patients. [ABSTRACT FROM AUTHOR]
