RESUMO
This study was undertaken to assess the efficacy of delayed primary closure in prevention of postoperative wound infection in patients with obstructive jaundice and septic abdomen. Here analyzed 93 patients retrospectively who underwent surgery in hepato-biliary-pancreatic unit of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2011 to June 2011. Primary closure of the abdominal wound was applied in all patients. There was no mortality, but 21 patients had postoperative morbidity (wound infection in 17, intra-abdominal abscess in 1, melaena in 1, biliary leakage in 1, burst abdomen in 1). Seventy-two patients had uneventful postoperative recovery were included in Group 1. Patients who developed postoperative wound infection (n=17) were included in Group 2. Rest 4 patients who developed other complications were excluded from the study. Pre-, per and postoperative parameters were compared between two groups for identifying the risk factors for SSI. Delayed primary closure of the wound was applied prospectively in 21 patients (Group 3) on the basis of retrospective results and the outcome was assessed. Retrospective analysis revealed that the patient who developed wound infections (Group 2) after primary closure; significantly greater number of patients had obstructive jaundice or intra-abdominal septic condition preoperatively. Prospective results revealed that there was no wound infection in 21 patients with in obstructive jaundice or intra-abdominal sepsis in which delayed primary closure was applied. Hospital stay was significantly reduced in Group 3 in compare to Group 2. In subsequent follow up, it has been found that 2 patients developed incisional hernia in Group 2 patients but none in Group 3 patients. Delayed primary closure of the wound is a good option in patient with obstructive jaundice and intra-abdominal septic condition for preventing postoperative wound infection.
