Accessible laparoscopic liver resection performed in low volume centers: Is it time for democratization?

INTRODUCTION: Laparoscopic liver resection (LLR) has been developed and is daily practiced by many expert teams. However, very few data are available on the experience of low volume centres. The aim of our study was to report and discuss the operative results of LLR performed in three low volume centres. METHODS: Records of patients who underwent a LLR in three low volume centres in France between May 2014 and November 2017 were collected. Endpoints studied were indications, intra and postoperative outcomes as well as short-term outcomes. RESULTS: A total of 46 patients (57 specimen resected) underwent a LLR during this period, representing 29.6% of total liver resections. Indications of LLR were benign lesions in 26%, primitive malignant lesions in 32.6% and metastatic tumours in 41.3%. Median size of lesions was 22mm (range 11-100). Most liver resections were non-anatomic (64.7%), while left lateral sectionectomies represented 19.2%. Five patients required conversion and there were at the end 3 specimen with margins inferior to 1mm resected laparoscopically. Postoperative mortality was nil and morbidity rate was 17.3%. Median hospital stay was 6 days (3-15). CONCLUSION: Although LLR have gained acceptance in surgeons' arsenal, it remains concentrated in referral centres. Our results suggest the feasibility of LLR in non-academic centres when it comes to small accessible lesions. Further studies would provide data about the long-term safety of this procedure in those centres.

The vision and role of geriatric oncology in surgical treatment of the elderly patient.

The phenomenon of population aging is constantly on the rise, as are the medical needs of elderly subjects. Oncological treatment concerns an ever larger number of elderly patients, raising a number of not only practical and medical questions, but also the ethical interrogations associated with therapeutic decision-making, quality of life and therapeutic obstinacy (futile medical care). Surgeons are increasingly preoccupied by elderly patients on account of the cancer rate among them, and they are compelled to cope with challenges such as morbimortality and prolonged hospitalization. Geriatric oncology is a discipline of increasing importance of which the goal consists in comprehensive care of the elderly cancer patient, care taking into full account his physical and psychological aging, his somatic and cognitive comorbidities, and, last but least, his life expectancy. The opinions and recommendations of geriatric oncologists provide increasingly more orientation for the oncological therapeutic decision-making processes. The objective of this attempt at clarification is to discuss the contributions of this discipline to everyday surgical activity, to provide surgeons with some tools facilitating initial evaluation of their patients, and to remind the reader of situations in which oncological assistance is of paramount importance.

Biliary leakage from gallbladder bed after cholecystectomy: Luschka duct or hepaticocholecystic duct?

Anatomic variations in the biliary tract are common and can cause difficulties when a cholecystectomy is performed. One of the most common ones are hepaticocholecystic ducts and Luschka ducts, connecting the gallbladder or its bed to the bile ducts but distinction between these two types of ducts can be difficult. We do discuss here the differences between these anatomical variations, their origin and their clinical implications. These aberrant ducts may go unnoticed and may require further complementary procedures in case of postoperative biliary leakage. In addition to a careful surgical procedure and an examination of the cystic bed in the end of the intervention, an intraoperative cholangiography should be performed as often as possible.

Hepatic artery ligation for arterial rupture following liver transplantation: a reasonable option.

Hepatic artery (HA) rupture after liver transplantation is a rare complication with high mortality. This study aimed to review the different managements of HA rupture and their results. From 1997 to 2007, data from six transplant centers were reviewed. Of 2649 recipients, 17 (0.64%) presented with HA rupture 29 days (2-92) after transplantation. Initial management was HA ligation in 10 patients, reanastomosis in three, aorto-hepatic grafting in two and percutaneous arterial embolization in one. One patient died before any treatment could be initiated. Concomitant biliary leak was present in seven patients and could be subsequently treated by percutaneous and/or endoscopic approaches in four patients. Early mortality was not observed in patients with HA ligation and occurred in 83% of patients receiving any other treatment. After a median follow-up of 70 months, 10 patients died (4 after retransplantation), and 7 patients were alive without retransplantation (including 6 with HA ligation). HA ligation was associated with better 3-year survival (80% vs. 14%; p=0.002). Despite its potential consequences on the biliary tract, HA ligation should be considered as a reasonable option in the initial management for HA rupture after liver transplantation. Unexpectedly, retransplantation was not always necessary after HA ligation in this series.

Tumor size of hepatocellular carcinoma in noncirrhotic liver: a controversial predictive factor for outcome after resection.

BACKGROUND: Hepatocellular carcinoma in noncirrhotic liver (NC-HCC) presents usually with large size, which is seen as a contraindication to liver transplantation (LT) or even resection. The objective of our single-center study was to identify prognostic factors following resection of large NC-HCCs and to subsequently devise a treatment strategy (including LT) in selected patients. METHODS: From 2000 to 2010, 89 patients who had hepatic resection for NC-HCC (large ≥ 8 cm in 52) were analyzed with regard to pathological findings, postoperative and long-term outcome. RESULTS: Five patients died postoperatively. After a mean follow-up of 35 ± 30 months, NC-HCC recurred in 36 patients (26/47 survivors in group 8 cm+, 10/37 in group 8 cm-; p = 0.007). Five-year overall (OS) and disease-free survival (DFS) rates were significantly worse for group 8 cm+ (43.4% vs. 89.2% and 39.3% vs. 60.7% for group 8 cm-, p < 0.05). Seven patients underwent re-hepatectomy and/or LT for isolated intrahepatic recurrence, with 5-year DFS of 57.1%. In a multivariate analysis, the factors associated with poor OS and DFS were vascular invasion and tumor size ≥ 8 cm in the overall population and vascular invasion, fibrosis and satellite nodules in group 8 cm+. Adjuvant transarterial chemotherapy was a protective factor in group 8 cm+. In 22 isolated NC-HCC cases with no vascular invasion or fibrosis, tumor size had no impact on five-year DFS (85%). CONCLUSIONS: Although patients with NC-HCC ≥ 8 cm had a poorer prognosis, the absence of vascular invasion or fibrosis was associated with excellent survival, regardless of the tumor size. In recurrent patients, aggressive treatment (including LT) can be considered.

Exposure for hepatic surgery in the obese patient: an innovative adaptation in time of need .

Obesity has become a major public health concern. More and more patients with substantial obesity require surgery including complex hepatobiliary interventions. The morphology of these patients can make surgery difficult, especially in terms of exposure. We report the case of an obese patient who required a left hemihepatectomy for colorectal liver metastasis. It was very difficult to obtain adequate exposure; this problem was solved by transcutaneous introduction of the handle of a broad costal margin retractor. We describe this maneuver, which allowed us to carry out the intervention under excellent conditions.

Laparoscopic resection vs. open liver resection for peripheral hepatocellular carcinoma in patients with chronic liver disease: a case-matched study.

BACKGROUND: Studies that compare laparoscopic to open liver resection for hepatocellular carcinoma (HCC) in cirrhotic patients are rare and may have suffered from low patient numbers. This work was designed to determine the impact of laparoscopic resection on postoperative and long-term outcomes in a large series of cirrhotic patients with hepatocellular carcinoma (HCC) compared with open resection. METHODS: From 2002 to 2009, 36 patients with chronic liver disease with complicating HCC were selected for laparoscopic resection (laparoscopic group, LG). The outcomes were compared with those of 53 patients who underwent open hepatectomy (open group, OG) during the same period in a matched-pair analysis. The two groups were similar in terms of tumor number and size and number of resected segments. RESULTS: Morbidity and mortality rates were similar in the two groups (respectively 25 and 0% in LG vs. 35.8 and 7.5% in OG; p = 0.3). Severe complications were more frequent in OG (13.2%) than in LG (2.8%; p = 0.09). Despite similar portal hypertension levels, complications related to ascites (namely evisceration or variceal bleeding) were fatal in 4 of 12 affected patients in OG but 0 of 5 cases in LG (p = 0.2). The mean hospitalization durations were 6.5 ± 2.7 days and 9.5 ± 4.8 days in LG and OG, respectively (p = 0.003). The surgical margins were similar in the two groups. Although there was a trend toward better 5-year overall survival in LG (70 vs. 46% in OG; p = 0.073), 5-year disease-free survival was similar (35.5 vs. 33.6%). CONCLUSIONS: Laparoscopic resection of HCC in patients with chronic liver disease has similar results to open resection in terms of postoperative outcomes, surgical margins, and long-term survival.

Management of blunt hepatic trauma.

Management of blunt liver trauma has progressed over the last 20 years with the adoption of conservative non-operative management (CM) as the gold standard in 80-90% of patients. Clinical and hemodynamic changes, and CT imaging guide the conservative attitude or pose an indication for urgent surgical intervention in unstable patients. The adoption of CM for blunt liver trauma has resulted in an increased incidence of late complications. These consist principally of persistent hemorrhage, fistulas and bile leaks, the abdominal compartment syndrome, and hepatic necrosis or abscess. These late complications can be managed secondarily by planned interventions via laparotomy or laparoscopy, interventional radiology and/or endoscopic techniques in a non-emergency setting as indicated by circumstances and with the benefit of multidisciplinary consultation. These secondary interventions should not be considered a failure of conservative treatment, but rather as an anticipated eventuality in the management of these patients.

Pre-operative management is associated with low rate of post-operative morbidity in penetrating Crohn's disease.

BACKGROUND: Ileocaecal resection for penetrating Crohn's disease is still challenging with a high rate of post-operative morbidity and faecal diversion. AIM: To report retrospectively the results of pre-operative management for penetrating Crohn's disease focusing on the rate of post-operative major morbidities and need for faecal diversion. METHODS: Between 1997 and 2007, 78 patients with penetrating Crohn's disease underwent a first ileocaecal resection after a pre-operative management consisting in bowel rest, nutritional therapy, intravenous antibiotics, weaning off steroids and immunosuppressors, and drainage of abscesses when appropriate. RESULTS: Resection was performed for terminal ileitis associated with (n = 41), abscesses (n = 37) or both (n = 5). A pre-operative nutritional therapy was performed in 50 patients (68%) for 23 days (range, 7-69 days) along with a weaning off steroids and immunosuppressors. A diverting stoma was performed for six patients (7.7%). There was no post-operative death. Post-operative complications were classified as minor in 10 patients (12.8%), and major in four patients (5%). Overall, the post-operative course was uneventful in 58 patients (74%). CONCLUSION: Pre-operative management for penetrating Crohn's disease allowed ileocaecal resection with low rates of post-operative morbidity and faecal diversion.

[Dermoid cyst of the diaphragm: a case report]. / Kyste dermoïde du diaphragme: un cas.

Dermoid cysts involving the diaphragm are rare and their symptomatology is non-specific. CT is the principal diagnostic tool, but it may fail to distinguish whether a cyst is located above, below, or within the diaphragm. Surgical excision of dermoid cysts is recommended because of the possibility of malignant degeneration.
