Outcomes of liver resection for huge hepatocellular carcinoma exceeding 10 cm in size: A single center experience.

BACKGROUND: To evaluate our experience of resection for huge hepatocellular carcinoma (HCC) (exceeding 10 cm in diameter). METHODS: We reviewed the patients' data who underwent liver resection for huge HCC between 2010 and 2019. We divided them into two groups according to liver resection extent (minor/major). RESULTS: 40 patients were included. Minor Group included 19 patients (47.5%), and Major Group included 21 patients (52.5%). Longer operation time, hospital stay, and more severe complications were found in Major Group. The 1-, 3-, and 5-years OS rates were 76.6%, 39.5%, and 39.5%, respectively. The 1-, 3-, and 5-year DFS rates were 65.6%, 40%, and 0%, respectively. There were no significant differences between the two groups regarding OS (p = 0.598) and DFS (p = 0.564). CONCLUSION: Liver resection for huge HCC is associated with average morbidities and mortality. Proper selection, adequate techniques and standardized care can provide favorable patients' survival.

Mirizzi Syndrome: How it could be a challenge.

BACKGROUND/AIMS: Mirizzi syndrome (MS) is a rare complication of cholelithiasis. This entity should be considered in the differential diagnosis of all patients with obstructive jaundice. Failure to recognize this condition preoperatively can result in a major bile duct injury. In this study, our aim is to describe the clinical presentations, investigations, operative details, endoscopic management and the complications of both procedures. METHODOLOGY: We performed a retrospective analysis on the records of 65 patients with MS. All patients had a cholangiogram; either magnetic resonance cholangiopancreatography (MRCP) or endoscopic retrograde cholangiopancreatography (ERCP). We used a McSherry classification to divide patients with MS into type I MS and type II MS. Those patients had undergone different types of management either ERCP and/or surgery. RESULTS: The incidence of MS was 0.98% from a total of 4600 patients who had undergone cholecystectomy. From 65 patients with MS, 20 patients underwent ERCP where it was the sole treatment (18 of which had stent while 2 had the stone extracted). The overall surgically treated patients were 45 (23 patients with preliminary ERCP with stent and 22 patients with primary surgical treatment), 18 patients had MS type I while 27 patients had MS type II. Patients with different types of MS underwent different types of surgical procedures.

Risk factors for conversion during laparoscopic cholecystectomy: retrospective analysis of ten years' experience at a single tertiary referral centre.

BACKGROUND/PURPOSE: Laparoscopic cholecystectomy (LC) is the standard treatment for symptomatic benign gallbladder disease. The identification of factors that reliably predict the need to convert LC to open cholecystectomy (OC) would help with patient education and counseling. METHODS: Between January 2000 and December 2009, 4,698 patients underwent cholecystectomy. LC was attempted in 4,434 patients (94.4%) and OC from the start was performed in 264 patients (5.6%). The causes for conversion were evaluated. The change in conversion rate between 2000 and 2004 and between 2005 and 2009 was analyzed. Factors predictive of conversion were identified by univariate and multivariate analysis. RESULTS: Conversion to OC from an initial LC approach was required in 234 patients (5.3%). The main cause for conversion was dense adhesions (54.7%). Independent risk factors in multivariate analysis were male gender (p < 0.001), increased age (p < 0.001), a history of previous upper abdominal surgery (p < 0.001), a WBC count >9 × 10(3)/µl, and urgently indicated cholecystectomy (p <0.001). The conversion rate decreased significantly from 6.7 to 3.6% over the two time intervals (p < 0.001). CONCLUSIONS: Those at highest risk for conversion are elderly male patients with prior abdominal surgery who present emergently with laboratory evidence of biliary inflammation.

Caudate lobe resection for hepatocellular carcinoma.

BACKGROUND/AIMS: Hepatocellular carcinoma (HCC) originating in the caudate lobe is rare, and the treatment for this type of carcinoma is a complex surgical procedure. We aimed to evaluate the surgical outcomes after isolated caudate lobe resection for HCC. METHODOLOGY: We retrospectively analyzed 30 consecutive patients with HCC originating in the caudate lobe who underwent isolated caudate lobe resection. RESULTS: Thirty patients underwent caudate lobe resection for HCC. The main sites of the tumors were located in the Spiegel lobe, the paracaval portion and caudate process. The surgical margin was tumor negative in all of the patients. The median tumor size was 4.3cm. The mean operative time was 230 ± 50min and the intraoperative blood loss was 1200 ± 200mL. The hospital morbidity rate was 33%. There was no postoperative mortality. The mean survival rate was 25.3+11.7 months. The overall survival rates were 62%, 34% and 11% at 1, 3 and 5 years, respectively. The disease free survival rate after isolated caudate lobectomy was 31% at 3 years. Recurrence was noted in 12 patients (40%). Eleven patients were identified as having intrahepatic recurrences and 1 patient as having peritoneal dissemination. CONCLUSIONS: Isolated caudate lobe resection is a feasible procedure and can be undertaken with low morbidity and nil mortality. Careful technique and detailed anatomic knowledge of the caudate lobe are essential for this procedure.

Post-cholecystectomy biliary injuries: one center experience.

BACKGROUND/AIMS: Post-cholecystectomy bile duct injuries (BDIs) represent a challenge in diagnosis and management. METHODOLOGY: From March 1995 to August 2009, 274 patients with post-cholecystectomy BDIs were managed at our center. All patients were subjected to laboratory tests, sonography, ERCP and MRCP. The management varied according to the type of injury. RESULTS: Seventy-one (25.9%) LC and 203 (74.1%) OC were performed; 8(2.9%) were detected intraoperatively; 270 patients were referred from other hospitals. From those discovered intraoperatively, 7 had hepatico-jejunostomy and one died from severe peritonitis; 11 (4%) presented with generalized and 112 (40.9%) with localized peritonitis. The leak site was the cystic duct (57 cases), accessory duct in the liver bed (5 cases), right hepatic duct (4 cases) and lateral tear in the CBD (12 cases). Endoscopic stenting was performed for all of them. The remaining 34 patients had a completely ligated distal duct and therefore had hepatico-jejunostomy Roux loop; 143 patients (52.2%) presented with early (79 cases) and late (64 cases) jaundice; 126 cases had hepatico-jejunostomy. The remaining 17 patients were treated by balloon dilatation. CONCLUSIONS: Endoscopic stenting can manage cases with cystic or accessory duct leak while, hepatico-jejunostomy Roux loop represents the golden procedure for management of transected or ligated CBD.
