Background: This prospective observational study attempts to compare the healing in the laparotomy midline wounds closed primarily with negative suction wound drain to those wounds where only linea alba was closed with skin and subcutaneous tissue left open for secondary suturing, in emergency colorectal surgeries. Materials and Methods: This study was conducted on 160 patients in the general surgery department of a tertiary care teaching hospital for 12 months in those who underwent emergency colorectal surgery through midline laparotomy and randomly allotted for either laparotomy midline wound closure with suction drain or closure with linea alba suturing alone with skin and subcutaneous tissue left open for secondary suturing. These two groups were compared for wound healing. Statistical analysis was performed using the SPSS software. Results: The wound contamination in those with closed wound with negative suction wound drain (Group A) had 40% in Grade II and 37.5% in Grade III, whereas those in which skin and subcutaneous tissue was left open after closing linea alba (Group B) had 53.8% in Grade II and 38.8% in Grade I and this might have contributed to the better healing as was seen in Group B than in Group A. This showed that wound healing was better in those wounds where only linea alba was closed with skin and subcutaneous tissue left open for secondary suturing after 1 week. Conclusion: In emergency colorectal surgeries, wound healing is better with reduced chance of surgical site infection in those wounds where only linea alba was closed with skin and subcutaneous tissue left open and secondary suturing was done after a week.
