Can laparoscopy be performed safely early after laparotomy?
Early subsequent laparotomy has high morbidity and mortality rates. The majority of these procedures, such as control of intraabdominal bleeding, management of intraabdominal sepsis, assessment of bowel viability, or anastomotic suture line, which are performed during early subsequent laparotomy, can be managed safely by laparoscopy, with resultant decreased mortality and morbidity rates. However, fear of dehiscence and ventral hernia prevents widespread use of laparoscopy. The aim of this experimental study was to compare the deleterious effects of subsequent laparotomy with laparoscopy in abdominal wounds during the early postceliotomy period. A 4-cm median laparotomy was performed in 120 Wistar-Albino rats that were classified into three groups. The control group (1) did not receive additional treatment. On the third postoperative day, early subsequent laparotomy and pneumoperitoneum were performed in group 2 and group 3 rats, respectively. Ten rats from each group were selected randomly and killed after 5 days, 1 week, 2 weeks, and 4 weeks. Bursting pressure and tensile strength of the abdominal wound were assessed. Results of the study showed impaired abdominal wound healing in subsequent laparotomy group rats (group 2) (P < 0.05). Pneumoperitoneum did not cause statistical differences in wound healing parameters when compared with control group rats (P > 0.05). In conclusion, pneumoperitoneum does not affect abdominal wound healing adversely, but early subsequent laparotomy impairs wound healing severely. Laparoscopy would be an alternative to high-risk early subsequent relaparotomy.
