COMPARATIVE STUDY BETWEEN TERNAMIAN BLADELESS TROCAR ENTRY and VISUAL TRANSPARENT BLADED TROCAR ENTRY in LAPAROSCOPIC PROCEDURES

COMPARATIVE STUDY BETWEEN TERNAMIAN BLADELESS TROCAR ENTRY and VISUAL TRANSPARENT BLADED TROCAR ENTRY in LAPAROSCOPIC PROCEDURES; a PROSPECTIVE RANDOMIZED CONTROLLED TRIAL

To compare the efficacy and safety between Ternamian bladeless trocar entry and visual, transparent bladed trocar entry in laparoscopic procedures. A prospective randomized controlled study will be conducted among 100 female patients who will be admitted to the department of Gynecology and Obstetrics at Kasr Alainy university hospital for diagnostic and/or therapeutic laparoscopic intervention. Patients will be randomly assigned (1:1) using computer-generated random numbers to undergo laproscopic entry either by the visual transparent bladed trocar or the Ternamian bladeless trocar.

Main outcome measures: entry time of trocar entry in seconds and visceral or major vascular injury during trocar entry.

Detailed Description

To compare the efficacy and safety between Ternamian bladeless trocar entry and visual transparent bladed trocar entry in laparoscopic procedures. A prospective randomized controlled study will be conducted among 100 female patients who were admitted to the department of Gynecology and Obstetrics at Kasr Alainy university hospital for diagnostic and/or therapeutic laparoscopic intervention. Patients were randomly assigned (1:1) using computer-generated random numbers to undergo laproscopic entry either by the visual transparent bladed trocar or the Ternamian bladeless trocar. Entry time in seconds starting from the moment the trocar is applied through the umbilical incision to the moment the peritoneal cavity is entered, guided by transmitted images on the monitor, will be used to assess the efficacy of the used trocar type. Complications including major vessel injury or visceral injury that maybe encountered during laparoscopic entry could be immediately detected in both groups through the transmitted in time monitor images to assess safety of the used trocar type.

Main outcome measures: entry time of trocar entry in seconds and visceral or major vascular injury during trocar entry.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Group A, (Visual transparent bladed trocar group); visual transparent bladed trocar of diameter 10 mm is used for abdominal entry; the assistant holds the laparoscope mounted in the cannula of the trocar, and the surgeon lowers the unit (laparoscope and mounted cannula) deep into the umbilical wound where the surgeon uses the muscles of the dominant wrist to rotate the cannula clockwise while keeping the forearm horizontal the patient's abdomen. Downwards axial pressure during rotation is kept to a minimum. Rotation serves to lift the anterior abdominal wall and transpose successive tissue layers onto the cannula's outer thread. The white anterior rectus fascia, red rectus fascia, pearly white posterior rectus fascia, yellowish preperitoneal space, and transparent greyish peritoneal membrane are all observed sequentially on the monitor. Further clockwise rotation parts the peritoneal membrane radially to advance the cannula incrementally into the peritoneal cavity under direct visual control while avoiding cannula overshot	Device: visual transparent bladed trocar of; visual transparent bladed trocar of diameter 10 mm and Ternamian bladeless trocar of diameter 10 mm
Group B ( Ternamian bladeless trocar group); Ternamian bladeless trocar of diameter 10 mm is used for abdominal entry; this trocar is hollow in which a laparoscope is loaded for the distal crystal tip to transmit real-time monitor images while transecting abdominal wall tissue layers. The assistant holds the laparoscope during entry allowing the wrist to move freely while the surgeon applies significant axial thrust through the dominant upper body muscles while twisting the handle to advance the trocar tip and dissect successive tissue layers on its way towards the abdomen. A considerable axial force is applied by the surgeon for the retention of the push-through trocar design with no mechanism to offset overshoot.	Device: Ternamian bladeless trocar; Ternamian bladeless trocar of diameter 10 mm
