Brief Summary

When the literature is examined, it has been reported in many studies that intracranial pressure increases due to laparoscopic procedures performed in the intraperitoneal area. The mechanism of increased intracranial pressure (ICP) associated with insufflation is most likely due to impaired venous drainage of the lumbar venous plexus at increased intra-abdominal pressure. Changes in ICP can be monitored by ultrasonographic measurement of optic nerve sheath diameter (ONSD), which is a generally accepted simple, reliable and non-invasive ICP measurement technique. In meta-analyses conducted on this subject, it has been revealed that ICP elevation during laparoscopy can be observed with a significant increase in ONSD in the early (0 30 minutes) and late (30-120 minutes) periods during carbondioxid (CO2) pneumoperitoneum. However, the effect of laparoscopic procedures performed in the extraperitoneal area on the central nervous system is not clear. There is not found any study in the literature comparing laparoscopic procedures, especially performed extraperitoneally and transperitoneally, and their effects on intracranial pressure. The aim of the study compare to laparoscopic cholecystectomy performed in the transperitoneal area and (totally extra-peritoneal) TEP inguinal hernia repair performed in the extraperitoneal area in terms of intracranial pressure relationship.

Study Arms (2)

extraperitoneal surgery group - TEP inguinal hernia repair

EXPERIMENTAL

The external sheath of the rectus muscle was seen by passing through the skin and subcutaneous tissue with a mini incision made from the umbilicus edge. A 10 mm trocar was placed in the preperitoneal area and CO2 insufflation was performed. The pressure was set to 14 mmHg. Two more 5 mm trocars were inserted between the umbilicus and the sympisis pubis under the laparoscope. The preperitoneal inguinal area was dissected with a laparoscopic dissector and grasper. The hernia sac was released. A 10x15 cm prolene mesh was spread and fixed to cover the femoral, direct and indirect hernia areas. The trocars were removed by evacuating the CO2 gas. The skin was closed and the operation was terminated.

Device: E-CUBE i7 ultrasound system (Alpinion Medical Systems, Seoul, Republic of Korea)

transperitoneal surgery group - laparoscopic cholecystectomy

ACTIVE COMPARATOR

With a mini incision made under the umbilicus, the abdomen was entered with a 10 mm trocar. Pneumoperitoneum was created with CO2 gas. Intra-abdominal pressure was set to 14 mmHg. Under the guidance of the laparoscope, one 10 mm trocar from the subxiphoid area and two more 5 mm trocars from the subcostal area were inserted. The cystic artery and cystic duct were clipped and cut by exposing the Callot triangle. Then the gallbladder was separated from the liver bed and taken out of the abdomen. The CO2 in the abdomen was evacuated and the trocars were removed. The fascia defect and skin were closed and the operation was terminated.

Device: E-CUBE i7 ultrasound system (Alpinion Medical Systems, Seoul, Republic of Korea)

Interventions

ONSD measurement will be made using the E-CUBE i7 ultrasound system.
