Comparison of open and laparoscopic live donor left lateral sectionectomy

Laparoscopic hepatectomy is associated with a higher incident frequency in hepatolithiasis patients

PURPOSES

The primary concern regarding laparoscopic hepatectomy in hepatolithiasis patients is surgical safety, which may be high in current practice.

METHODS

Hepatolithiasis patients who underwent laparoscopic and laparotomic hepatectomies were retrospectively studies after being matched for age, location of gallstones, liver resection and underlying liver conditions at a ratio of 1:1 (n = 44 in each group). The rates of intraoperative incidents and postoperative complications were examined using validated classification and grading systems. The primary outcome measure was the procedure-related complication/mortality rate.

RESULTS

Laparoscopy was converted to open surgery in three patients (6.8 %). The length of the operation for laparoscopic hepatectomy was significantly longer than that for laparotomic hepatectomy (277.5 min [range, 190-410 min] vs. 212.5 min [140-315 min], P < 0.001). The two groups had similar intraoperative blood loss (367.5 mL [150-1200 mL] vs. 392.5 mL [200-1400 mL], P > 0.05) and transfusion frequencies (13.6 vs. 18.2 %, P > 0.05). The laparoscopy group had a higher percentage of patients with at least one intraoperative incident compared with the laparotomy group (22.7 vs. 6.8 %; P < 0.05). Vascular events occurred in nine patients (20.5 %) undergoing laparoscopy and two patients (4.5 %) undergoing laparotomy (OR 5.4 [95 %CI, 1.1-26.7], P < 0.05).

CONCLUSIONS

Laparoscopic hepatectomy is associated with a higher risk of intraoperative vascular incidents in hepatolithiasis patients compared wit laparotomy.

Laparoscopy in Liver Transplantation: The Future has Arrived

In the last two decades, laparoscopy has revolutionized the field of surgery. Many procedures previously performed with an open access are now routinely carried out with the laparoscopic approach. Several advantages are associated with laparoscopic surgery compared to open procedures: reduced pain due to smaller incisions and hemorrhaging, shorter hospital length of stay, and a lower incidence of wound infections. Liver transplantation (LT) brought a radical change in life expectancy of patients with hepatic end-stage disease. Today, LT represents the standard of care for more than fifty hepatic pathologies, with excellent results in terms of survival. Surely, with laparoscopy and LT being one of the most continuously evolving challenges in medicine, their recent combination has represented an astonishing scientific progress. The intent of the present paper is to underline the current role of diagnostic and therapeutic laparoscopy in patients waiting for LT, in the living donor LT and in LT recipients.

Laparoscopic living donor hepatectomy

Shortage of deceased donor organs led to establishment of living donor liver transplantation. Recent reports have strongly suggested that laparoscopic approach should be the gold standard for lesions in the left lateral section. Laparoscopic living donor left lateral sectionectomy was first described in 2002. Subsequently, laparoscopic procurement of left lateral sections was shown to be safe and reproducible, resulting in grafts similar to those obtained with open surgery. In 2006, laparoscopy-assisted right lobe donor hepatectomy was reported. To date, however, only a small number of liver transplant centers have performed laparoscopic donor hepatectomy because the procedure can be performed only by surgical teams with extensive expertise in performing both minimally invasive surgery on the liver and liver transplantation with partial and living donor liver grafts. Herein, we describe the details of laparoscopic living donor hepatectomy including total laparoscopic surgery and laparoscopy-assisted surgery.

Non-cirrhotic liver tolerance to intermittent inflow occlusion during laparoscopic liver resection

While inflow occlusion techniques are accepted methods to reduce bleeding during open liver surgery, their use in laparoscopic liver resections are limited by possible effects of pneumoperitoneum on ischemia-reperfusion liver damage. This retrospective study was designed to investigate the impact of intermittent pedicle clamping (IPC) on patients with normal liver undergoing minor laparoscopic liver resections. Three matched groups of patients were retrospectively selected from our in-house database: 11 patients who underwent robot-assisted liver resection with IPC, and 16 and 11 patients who underwent robot-assisted liver resection without IPC and open liver resection with IPC, respectively. The primary end point was to assess differences in postoperative serum alanine, aspartate aminotransferase (ALT and AST) and bilirubin levels. The curves of serum AST, ALT and bilirubin levels in a span of time of five postoperative days were not significantly different between the three groups. IPC has no relevant effects on ischemia-reperfusion liver damage even in the presence of pneumoperitoneum.
