Advancing mid-rectal cancer surgery: Unveiling the potential of natural orifice specimen extraction surgery in comparison to conventional laparoscopic-assisted resection.

Background: Mid-rectal cancer treatment traditionally involves conventional laparoscopic-assisted resection (CLAR). This study aimed to assess the clinical and therapeutic advantages of Natural Orifice Specimen Extraction Surgery (NOSES) over CLAR.

Aims: To compare the clinical outcomes, intraoperative metrics, postoperative recovery, complications, and long-term prognosis between NOSES and CLAR groups.

Laparoscopic natural orifice specimen extraction, a minimally invasive surgical technique for mid-rectal cancers: Retrospective single-center analysis and single-surgeon experience of selected patients.

Objective: To evaluate the feasibility, safety, and short-term outcomes of middle rectal resection followed by transanal specimen extraction.

Methods: Forty-four patients with small mid-rectal tumors underwent laparoscopic rectal resection followed by transanal specimen extraction.

Results: The procedure was successful in all patients without intraoperative conversion or additional access.

[Analysis of prognostic factors and treatment of pulmonary metastasis from colorectal cancer].

Objective: To investigate effect of the treatments and prognostic factors of patients with pulmonary metastasis from colorectal cancer.

Methods: Clinical data of 79 patients who suffered from lung metastatic diseases from colorectal cancer in 1990 - 2010 were retrospectively analyzed. The number of patients who had received lung operation was 22, and non-operated group contained 57 patients.

Integrated ratio of metastatic to examined lymph nodes and number of metastatic lymph nodes into the AJCC staging system for colon cancer.

Objective: At present, only the number of metastatic lymph nodes (LNs+) is used for the pN category of AJCC TNM system for colon cancer. Recently, the ratio of metastatic to examined lymph nodes (LNR) has been reported to represent powerful independent predictive capacity in colon cancer. We sought to propose a novel category (nLN) which intergrades LNR and LNs+ into the AJCC staging system for colon cancer.

Cost comparison between hand-assisted laparoscopic colectomy and open colectomy.

Purpose: Our aim was to compare the costs associated with hand-assisted laparoscopic colectomy (HALC) and open colectomy (OC).

Methods: The data of patients who underwent either HALC or OC between March 2009 and August 2010 were retrospectively reviewed. The assessed short-term outcomes included operative time, blood lost, retrieved lymph nodes, conversion rates, and complications.
