[Treatment of severe post-resection liver failure. Analysis of the specialized center]

Posthepatectomy liver failure is one of the most serious complications of large liver resections.

OBJECTIVE

The analyzes the management and results of treatment of patients with severe posthepatectomy liver failure (Grade C ISGLS) in a specialized hepatosurgical department.

MATERIAL AND METHODS

In the period from January to December 2019, 175 liver resections were performed in the Department of liver and pancreatic surgery at the A.S. Loginov Moscow Clinical Scientific Center. Major-volume liver resections (hemihepatectomies and resections of more than three liver segments) were performed in 80 (45%) patients. In 125 (71%) cases liver resctions were performed for malignant liver and bile duct diseases. Laparoscopic liver resections were performed in 77 (44%) patients.

RESULTS

Postresection liver failure developed in 18 (10.2%) patients. Severe (class C according to ISGLS) developed in 6 (3.4%) patients. In the postoperative period (90-day mortality), 4 patients (2.3%) died, while in two patients, mortality was not associated with liver failure. Hyperbilirubinemia was observed for more than 5 days in 2 (33.3%), coagulopathy in 4 (66.6%), ascites in 5 (83.3%), encephalopathy in 5 (83.3%), hypoglycemia in 3 (50%), and uncontrolled sepsis in 2 (33.3%) patients, respectively. Correction of surgical complications was required in 100% of cases, which consisted in drainage of abscesses and abdominal bylomas, and the the bilio-digestive anastomosis fistulas. Inotropic support was required in all 6 (100%) patients, invasive ventilation in 4(66.6%), and extracorporeal detoxification in 5 (83.3%).

CONCLUSIONS

Posthepatectomy liver failure is a complex problem even in a specialized center. A comprehensive approach to treatment allows to achieve noticeable results and reduce mortality.

[Early outcomes of robot-assisted liver resection]

AIM

To assess an experience of robot-assisted liver resection using CUSUM-test.

MATERIAL AND METHODS

The results of 46 robot-assisted liver resections were retrospectively analyzed by using of CUSUM-test.

RESULTS

There were 3 periods in development of the technology. The 1^st period - procedures with the lowest index of difficulty (n=16), the 2^nd period - expansion of the indications for difficult resections (n=18) and the 3^rd period - stabilization of the results (n=12). The dynamics of difficulty index, intraoperative blood loss, duration of procedure and morbidity (Clavien-Dindo Grade II-V) were evaluated. Five liver resections were needed to decrease blood loss and duration of the procedure. Expansion of indications was feasible after 16 procedures. Stable results were obtained after 34 liver resections.
