To explore the characteristics and risks of cancer in endoscopically unresectable polyps and compare the surgical outcomes of different operations.A retrospective review of 40 patients undergoing surgical operations for polyps unresectable at colonoscopy between August 2006 and July 2012 from Department of Gastrointestinal Surgery was performed. The follow-up period was 3 to 72 months (median: 24.5 months).The rate of endoscopically unresectable polyps with invasive cancer was 67.5% (27/40). And it was significantly influenced by patient age and number of polyps (both P0.01). Perioperative volume of blood loss ((86 ± 58) ml vs (44 ± 32) ml, P = 0.0066), time to first flatus ((2.7 ± 1.3) d vs (1.7 ± 0.6) d, P = 0.0018), incidence of complication (2 cases vs 0, P = 0.0365) and hospital stay ((11.2 ± 1.0) d vs (15.0 ± 5.0) d, P = 0.0164) were significantly different between open colectomy and laparoscopic group. And the long-term survival outcomes were similar in both groups (90.9% (10/11) vs 100.0% (27/27), 90.9% (10/11) vs 96.3% (26/27), both P0.05).Endoscopically unresectable polyps of colon and rectum have high malignancy rate. Polyps in elderly patients and multiple polyps are more likely to develop invasive cancer. Long-term outcomes are similar between open colectomy and laparoscopic colectomy groups, but laparoscopic group has better short-term outcomes. For endoscopically unresectable polyps, laparoscopic colectomy may be the first choice. |
