Comparison between segmental left and extended right colectomies for obstructing left-sided colonic carcinomas

Area of Science:

• Surgical Oncology
• Colorectal Surgery
• Gastrointestinal Oncology

Background:

• Obstructed left-sided colonic carcinomas present unique surgical challenges.
• Surgical options include radical extended right colectomy or segmental left colectomy with decompression.
• Comparing outcomes of these procedures is crucial for optimal patient management.

Purpose of the Study:

• To compare complications and functional outcomes between radical extended right colectomy and radical segmental left colectomy for obstructed left-sided colonic carcinomas.
• To evaluate the impact of colonic decompression during segmental left colectomy on patient outcomes.

Main Methods:

• A study involving 103 patients with obstructed left-sided colonic carcinoma.
• Patients underwent either radical extended right colectomy without decompression or radical segmental left colectomy with intraoperative decompression.
• Primary resection and anastomoses were performed in all cases.

Main Results:

• No significant difference in complications: 0 leaks/sepsis in the right colectomy group (44 patients) vs. 1 leak in the left colectomy group (59 patients).
• Median hospital stay was 14 days for both groups, with similar ranges.
• Bowel function showed transient differences at one month but normalized by six months in both groups.

Conclusions:

• No significant difference in bowel function or complication rates between radical extended right colectomy and segmental left colectomy for left-sided colon cancer.
• Both surgical techniques are viable options for managing obstructed left-sided colonic carcinomas.
• Intraoperative decompression in segmental left colectomy did not lead to significantly different outcomes compared to extended right colectomy.
