Review Comparative Study
Extraperitoneal laparoscopic hernia repair with local anesthesia.
This review aimed to compare laparoscopic preperitoneal herniorrhaphy (LPPH) using a laryngeal mask airway and local anesthesia with conventional open herniorrhaphy using similar anesthetic conditions. ⋯ The use of a long-acting local anesthetic, (30 ml of 0.5% bupivacaine via laryngeal mask airway) for laparoscopic preperitoneal hernia repair compared favorably with conventional open hernia repair using similar anesthetic techniques.

Randomized Controlled Trial Comparative Study Clinical Trial
Preinsertion local anesthesia at the trocar site improves perioperative pain and decreases costs of laparoscopic cholecystectomy.
Local anesthesia at the trocar site in laparoscopic cholecystectomy is expected to decrease postoperative pain and hence expedite recovery. The aims of this prospective randomized study were to investigate the effect of local anesthesia and to discover whether it is cost effective. ⋯ Preinsertion of local anesthesia at the trocar site in laparoscopic cholecystectomy significantly reduces postoperative pain and decreases medication usage costs.

Traumatic rupture of diaphragm is caused by blunt or penetrating trauma. Early diagnosis is difficult, and complications such as visceral herniation may arise. A 10-year evaluation of all diagnostic procedures used in patients with surgically proved traumatic rupture of the diaphragm is presented. ⋯ All the diagnostic methods investigated in this study showed unsatisfying results, and traumatic rupture of the diaphragm seems to remain a diagnostic dilemma. Endoscopic techniques not tested in this study and discussed controversially may offer a good chance for early diagnosis and repair of the injured diaphragm.

Head-mounted display (HM) units are used in various industries, but they have been tried only recently in surgery. In this study, we evaluated whether a commercially available HMD would improve or impede a laparoscopic task-in this case, suturing. ⋯ In this experimental model, the HMD we utilized did not appear to improve laparoscopic suturing. More developments, such as improved depth perception and better resolution, may increase its usefulness for laparoscopic tasks.

Comparative Study
Does a laparoscopic approach to total abdominal colectomy and proctocolectomy offer advantages?
Controversy exists regarding the feasibility, safety, and outcomes of laparoscopic total abdominal colectomy (LTAC) and laparoscopic total proctocolectomy (LTPC). The object of this study was to assess the outcomes of LTAC and LTPC and compare them with those of institutional open procedure used as controls. ⋯ The results indicate that LTAC can be performed safely with a statistically significant reduction in wound and long-term postoperative complications, as compared with its open counterpart. Operating time is increased, but there is a marked reduction in length of hospital stay. Preliminary results demonstrate that LTPC also is technically feasible and safe, with equal morbidity, mortality, and hospital stay, as compared with open procedures. Studies with larger numbers of patients and a randomized controlled trial giving special attention to patient quality-of-life issues are needed to elucidate the real advantages of this minimally invasive technique.
