Laparoscopic repair of an internal supravesical hernia: a rare hernia causing small bowel obstruction.

The application of diagnostic laparoscopy in emergency surgery has facilitated a wide range of endoscopic operative procedures. We report an extremely rare case of a patient who had a bowel obstruction caused by an internal supravesical hernia that was repaired via a minimally invasive technique. Abdominal computed tomography (CT) showed signs of small bowel obstruction: the cause was thought to be an invagination due to a small bowel tumor. Laparoscopic exploration of the dilated small bowel segments allowed the diagnosis of supravesical hernia. Reduction was performed with slight traction, and the hernial orifice was closed with intracorporeal sutures. To our knowledge, this is the first repair of an internal supravesical hernia ever to receive herniorraphy based on laparoscopic techniques. The mean starting time for bowel-function and mean hospital stay following the laparoscopic release of the intestinal obstruction were significantly shorter than is typically seen with standard techniques.

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.

Value of diagnostic laparoscopy in tuberculous peritonitis.

OBJECTIVE: To assess the safety and efficacy of diagnostic laparoscopy in patients with tuberculous peritonitis. DESIGN: Retrospective clinical study. SETTING: University hospital, Turkey. SUBJECTS: 8 patients (2 women, 6 men; mean age 26 years) who presented with tuberculous peritonitis between January 1994 and January 1996. INTERVENTION: Laparoscopy under local anaesthesia with sedation (the 4 who presented with ascites) and laparotomy (the 4 who presented with an acute abdomen). MAIN OUTCOME MEASURES: Clinical and laboratory findings, biochemical and microbiological analysis of ascites, histopathological examination of specimens, morbidity, and mortality. RESULTS: 4 patients presented with ascites, and 4 with adhesions. Ascites; adhesions between liver and diaphragm, liver and intestines, and intestines and the abdominal wall; miliary nodes on the peritoneal surface; and inflamed haemorrhagic areas on the peritoneum could all be seen at laparoscopy. One of the 8 patients who underwent laparotomy developed a spontaneous enterocutaneous fistula during the early postoperative period. Two of eight patients died, one of an early enterocutaneous fistula and the other of cor pulmonale 3 1/2 months later. The remaining 6 patients survived without complications after antituberculous medical treatment. CONCLUSIONS: Laparoscopy is a safe and accurate method of diagnosis of tuberculous peritonitis.

The effect of pneumoperitoneum on bacterial clearance and RES functions in a model of E. coli peritonitis.

The use of laparoscopic surgery in peritonitis has increased rapidly. The present study examined the effects of pneumoperitoneum on bacterial clearance. Spraque-Dawley rats were divided into six groups of seven animals. In groups 1 and 4, laparotomy with a midline incision was performed and 10(9) E. coli in a volume of 1 ml inserted into the peritoneal cavity. Groups 2, 3, 5, 6 received an identical quantity of E. coli by intraperitoneal injection. Groups 3 and 6 received carbon dioxide pneumoperitoneum at a constant pressure of 5 mmHg for 60 minutes after intraperitoneal injection of E. coli. In one hour groups; the mean bacterial counts per lung from the E. coli injection with laparotomy group was significantly higher than for the E. coli injection with pneumoperitoneum group (p < 0.05). The mean bacterial counts per kidney in the E. coli injection with laparotomy group was higher compared with the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.0001). There was statistically significant difference in quantitative bacteraemia between the E. coli injection with laparotomy group and the E. coli injection or E. coli injection with pneumoperitoneum groups (p < 0.05). In four-hour groups; the mean bacterial counts of lungs and liver-spleen were significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05 and p < 0.001 respectively). The quantitative bacteria was significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05). This study demonstrates that pneumoperitoneum impairs the clearance of bacteria from the peritoneal cavity in an experimental model of peritonitis. However, we could not detect the deleterious effects of pneumoperitoneum compared with laparotomy.
