title: Combined laparoscopic-assisted right hemicolectomy and low anterior resection for synchronous colorectal carcinomas.
abstract: BACKGROUND
  Two cases of combined laparoscopic- assisted right hemicolectomy and low anterior resection for malignancy are presented to illustrate the technical aspects of performing two concurrent laparoscopic-assisted bowel resections with sequential anastomosis. Although there are similarities with laparoscopic-assisted total proctocolectomy, the need for complete mesenteric dissection in two areas, removal of two separate specimens containing malignancy, and the need for two anastomoses raise unique technical considerations which include port placement, sequence of dissection, choice of specimen extraction sites, specimen handling, and sites for extracorporeal anastomosis.
  
  
  METHODS
  Operative notes, operative videotapes, and hospital inpatient and outpatient records were reviewed for both patients.
  
  
  RESULTS
  Laparoscopic-assisted combined resection was completed in both patients. In both cases, laparoscopic total mesorectal excision was performed. Maximum incision length was 6 cm. Both patients were ready for discharge on postoperative day 3.
  
  
  CONCLUSIONS
  Combined laparoscopic assisted right colectomy and low anterior resection can be performed for synchronous colorectal malignancies with curative intent.
