ABSTRACT
BACKGROUND AND OBJECTIVES: At present, we do not have a reliable method for the early diagnosis of colorectal anastomotic leakage (AL). We tested peritoneal flexible endoscopy through a port placed in the abdominal wall in the early postoperative course, as a new diagnostic method for detection of this complication and evaluated the suggested method for safety, feasibility, and accuracy. METHODS: Ten swine were randomized into 2 groups: group A, colorectal anastomosis without leakage; and group B, colorectal anastomosis with leakage. A button gastrostomy feeding tube was inserted percutaneously into the peritoneal cavity. Colorectal anastomosis (with or without defect) was created 48 hours after the first operation. The swine were examined by peritoneal flexible endoscopy 8 and 24 hours after the colonic operation, by a consultant surgeon who was blinded to both the presence and the allocated location of the of the anastomotic defect. RESULTS: None of the animals showed signs of illness 48 hours after the intraperitoneal gastrostomy tube placement. More than half of the anastomosis circumference was identified in 60 and 10% of the animals at endoscopy 8 and 24 hours, respectively, after the anastomosis was created. Excessive adhesion formation was observed in all animals, irrespective of AL. The sensitivity and specificity of endoscopy in detecting peritonitis 24 hours after AL were both 60%. CONCLUSIONS: Peritoneal endoscopy is a safe and simple procedure. Visualization of the peritoneal cavity in the early postoperative course was limited due to adhesion formation. Further studies are needed to clarify the accuracy of the procedure and to address additional methodological concerns.

INTRODUCTION: Incisional hernia following laparotomy remains an important problem. Laparoscopic repair has become the method of choice in recent years. The present article presents the outcome of laparoscopic incisional hernia mesh repair at Viborg Hospital in the years 2003-2006. MATERIAL AND METHODS: We retrospectively identified 114 patients who had undergone laparoscopic hernia repair during the relevant period. The patients received a questionnaire regarding satisfaction, pain and recurrence. Patients reporting any inconvenience were offered a consultation. RESULTS: Among the 114 included patients, ten procedures were converted to open laparotomy, six of which were converted due to recognized bowel injury. One case of bowel injury was managed laparoscopically. One case of bowel injury was recognized during reoperation the following day. Another four patients experienced reoperations for other reasons, mainly bleeding. The mean hospital stay was one day. A total of 12 patients had a recurrent hernia. The mean follow-up was 14 months. CONCLUSION: We conclude that laparoscopic incisional hernia repair is a useful surgical procedure with short hospital stay and high patient satisfaction. There is, however, a certain risk of bowel injury associated with this procedure.
