Evaluation of the efficacy of natural orifice specimen extraction surgery versus conventional laparoscopic surgery for colorectal cancers: A systematic review and meta-analysis.

Aim: Natural orifice specimen extraction surgery (NOSES) has gained significant importance in treating cancers. The current study is a meta-analysis that aimed to assess the short-term efficacy and long-term prognostic impact of NOSES and conventional laparoscopic (CL) surgery in the treatment of colorectal cancer (CRC).

Method: Published reports in several medical databases up to February 2024 were searched and information pertinent to outcomes of NOSES and CL in retrospective and randomized studies to treat CRC was collected.

Short- and long-term outcomes after surgical treatment of 5918 patients with splenic flexure colon cancer by extended right colectomy, segmental colectomy and left colectomy: a systematic review and meta-analysis.

Background: Colorectal cancer is among the most common cancers in the world, and splenic flexure colon cancer accounts for about 2-5% of them. There is still no consensus on the surgical treatment of splenic flexure colon cancer (SFCC), and the extent of surgical resection and lymph node dissection for SFCC is still controversial.

Aim: To compare the postoperative and long-term oncologic outcomes of extended right colectomy (ERC), segmental colectomy (SC) and left colectomy (LC) for SFCC.
