Dual trocar laparoscopy improves reduced-port surgery of the distal pancreas.

Background: The technical feasibility of transumbilical single-incision surgery (SIL) for pancreatic resections has been demonstrated. However, this technique is hampered by the limited degrees of freedom for instrument handling. Dual-incision laparoscopy (DIL) with an additional trocar may simplify dissection and allow drainage.

The Shift from Multiport to Single Port Increases the Amount of Bleeding in Laparoscopic Major Hepatectomy.

Background: Bleeding is a negative outcome predictor in liver surgery. Reduction in the abdominal wall trauma in major hepatectomy is challenging but might offer possible benefits for the patient. This study was conducted to assess hemostasis techniques in single-port major hepatectomies (SP-MajH) as compared to multiport major hepatectomies (MP-MajH).

Inline radiofrequency pre-coagulation simplifies single-incision laparoscopic minor liver resection.

Background: Single-incision laparoscopy (SIL) has been developed to reduce surgical trauma, whereas technical difficulties in bleeding control limit the broad acceptance for hepatectomy. A novel minimized invasive strategy combining inline radiofrequency pre-coagulation and transumbilical SIL is presented herein.

Methods: A cohort of 21 selected patients underwent transumbilical SIL hepatectomies (segmentectomies II-VI) utilizing inline radiofrequency pre-coagulation for hepatic transection (Habib 4X).

Single port laparoscopy in gastroenterology and hepatology: a fine step forward.

Single incision laparoscopy (SIL) has become an emerging technology aiming at a further reduction of abdominal wall trauma in minimally invasive surgery. Available data is encouraging for the safe application of standardized SIL in a wide range of procedures in gastroenterology and hepatology. Compared to technically simple SIL procedures, the merit of SIL in advanced surgeries, such as liver or colorectal interventions, compared to conventional laparsocopy is self-evident without any doubt.

Wound complications in 1145 consecutive transumbilical single-incision laparoscopic procedures.

Objective: To evaluate the wound complication rate in patients undergoing transumbilical single-incision laparoscopic (SIL) surgery.

Background: SIL surgery claims to be less invasive than conventional laparoscopy. Small SIL series have raised concerns toward a higher wound complication rate related to the transumbilical incision.

Single incision laparoscopic sigmoid colon resections without visible scar: a novel technique.

Objective: On the way to 'no-scar' techniques we developed a novel method for colorectal resection utilizing three intraumbilical trocars which results in a nonvisible postoperative scar.

Method: Two female patients (Age: 56a, 42a) underwent laparoscopic colorectal resection for diverticulitis and infiltrating endometriosis of the rectosigmoid colon, respectively. The entire operation was carried out transumbilically following the standardized principles of colorectal resection.

Optimizing ischemia/reperfusion in the failing rat heart--improved myocardial protection with acute ACE inhibition.

Background: Whereas the number of patients with reduced left ventricular function after myocardial infarction who need revascularization is increasing, the operative outcome is still inadequate. Consequently, drugs that increase myocardial perfusion and decrease oxygen consumption of the remodeled myocardium are of particular interest to cardiac surgeons. Angiotensin-converting enzyme inhibitors (ACE-I) provide this pharmacologic profile.

Quinaprilat during cardioplegic arrest in the rabbit to prevent ischemia-reperfusion injury.

Objectives: This study evaluated intracardiac angiotensin-converting enzyme inhibition as an adjuvant to cardioplegia and examined its effects on hemodynamic, metabolic, and ultrastructural postischemic outcomes.

Methods: The experiments were performed with an isolated, erythrocyte-perfused, rabbit working-heart model. The hearts excised from 29 adult New Zealand White rabbits (2950 +/- 200 g) were randomly assigned to four groups.

Diltiazem during reperfusion preserves high energy phosphates by protection of mitochondrial integrity.

Objective: This study evaluates the effects of diltiazem administered during reperfusion on hemodynamic, metabolic, and ultrastructural postischemic outcome.

Methods: Hearts of 38 adult White New Zealand rabbits underwent 60 min of global cold ischemia followed by 40 min of reperfusion in an erythrocyte perfused isolated working heart model. Hearts were randomly assigned to four groups and received diltiazem (0.
