OBJECTIVE The direct trocar technique is an alternative to Veress needle insertion and open laparoscopy for accessing the abdominal cavity for operative laparoscopy. We review our approach to abdominal entry in 1385 laparoscopies performed between September 1993 and June 2000 by our group at Stanford University Hospital, a tertiary Medical Center. METHODS We performed a retrospective chart re...

Objective: To investigate the safety profile of image-guided drainage using the trocar technique. Methods: The medical records of 93 patients undergoing image-guided drainage procedures using the trocar technique at a local regional hospital from September 2004 to December 2006 were reviewed. Results: There were no incidences of significant neurovascular or adjacent organ damage. Conclusion: In...

BACKGROUND The majority of laparoscopic complications occur at the time of Veress needle and trocar insertion. Although not very frequent, they increase the morbidity and mortality of both diagnostic and operative laparoscopic procedures. Alternative techniques of trocar insertion have been described but have not completely eliminated the risk of injury. TECHNIQUE After Veress needle insertio...

OBJECTIVES Blunt-tipped trocar placement may eliminate the need for fascial closure in transperitoneal laparoscopic live donor nephrectomies (LDN). The process of 12-mm blunt-tipped trocar insertion through the abdominal wall involves fascial and muscle spreading, not incision. Coaptation of the tissue layers occurs during withdrawal of the trocar, preventing volume gaps that can be prone to he...

This paper presents a new method to calculate and display an approximated workspace of a surgical robot in nearly realtime. Displaying this information on a screen in the operation room could support the surgeon during intraoperative trocar placement for teleoperated minimally invasive robotic surgery (MIRS). We give a short overview on existing trocar placement procedures in teleoperated MIRS ...

PURPOSE Several risk factors for development of reexpansion pulmonary edema (REPE) after drainage of pneumothoraces have been reported, but the association between the method of thoracostomy and the development of REPE is unknown. The aim of this study was to compare the frequency of REPE after treatment of spontaneous pneumothorax with trocar or hemostat assisted closed thoracostomy. MATERIA...

Figure 2 Glove stretched over the retractor, providing a seal Figure 3 Glove port with camera inserted removal (Fig 1). This technique can also be used at a stoma site. Once the specimen is removed, stretch a sterile size 61⁄2 glove over the retractor and re-establish pneumoperitoneum. A perfect seal will be obtained (Fig 2). If the port is still required, cut the tip off any finger of the glov...

BACKGROUND Nonbladed trocars are considered less traumatic to the abdominal wall due to the lack of fascial incision. It has been suggested that closure of the abdominal fascia may be unnecessary when such nonbladed trocars are used. CASE REPORT We report on 2 patients who were diagnosed with trocar-site hernias 2 days after laparoscopic appendectomy performed using 11-mm nonbladed trocars. ...
