Abdominal colectomy offers safe management for massive lower GI bleed

Area of Science:

• Gastroenterology
• Surgical Oncology
• Emergency Medicine

Background:

• Preoperative localization for lower GI bleeding is debated.
• Limited colonic resection is presumed to have lower morbidity/mortality than total abdominal colectomy.
• Extensive preoperative evaluation can delay surgery in actively hemorrhaging patients.

Purpose of the Study:

• To analyze mortality and morbidity of total abdominal colectomy (TAC) versus limited colonic resection (LIM) for massive lower GI hemorrhage.
• To evaluate the safety and efficacy of TAC in managing acute LGI bleeding.

Main Methods:

• Retrospective analysis of 61 patients with massive LGI bleeding (≥1 unit PRBCs preoperatively) over 5 years.
• Data collected included preoperative/total PRBCs, Apache score, age, resection type (LIM vs. TAC), time to surgery, morbidity, and mortality.
• Statistical analysis using Student's t-test.

Main Results:

• Patients in TAC group had similar preoperative/total PRBCs compared to LIM group.
• Time to surgery was significantly shorter in the TAC group (73.7 hrs) versus the LIM group (95.4 hrs).
• No significant differences in Apache score, age, morbidity, or mortality rates (LIM 15%, TAC 6%) between groups. No intractable diarrhea observed.

Conclusions:

• Total abdominal colectomy is a safe and viable option for treating massive lower GI hemorrhage.
• TAC may offer advantages by potentially reducing delays in surgical intervention for critical patients.
• Further research may explore optimal timing and patient selection for TAC in massive LGI bleeding.
