Abstract:
Minimally invasive surgical techniques and procedures continue to evolve with the trend toward fewer and smaller instruments. To our knowledge, this is the first reported case of sigmoid colon resection utilizing needlescopic technology. The patient was a 53-year-old woman diagnosed with a malignant lesion in the midsigmoid colon at 30 cm. A subsequent needlescopic sigmoid colon resection was performed and the patient was discharged home after an uneventful postoperative course. This case demonstrates that colon procedures that require major reconstruction may be performed needlescopically in selected patients.
