Surgical Aspects of Intrahepatic Cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (ICC) is a rare and aggressive malignancy. It originates from the bile ducts and is the second most common primary cancer of the liver. Surgery is considered the only curative treatment of ICC, offering the best chance for long-term survival.

Perioperative and Oncological Outcomes of Combined Hepatectomy with Complete Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy for Metastatic Colorectal Cancer.

Background: Synchronous peritoneal and liver metastasis in colorectal cancer is a relative contraindication for curative surgery. We aimed to evaluate the safety and oncological outcomes of combined treatment of peritoneal and liver metastasis.

Methods: We conducted a retrospective analysis of metastatic colorectal cancer patients from two prospective databases: peritoneal surface malignancy (n = 536) and hepatobiliary (n = 286).

Development and Validation of a Nomogram for Early Detection of Malignant Gallbladder Lesions.

Objectives: Preoperative decision-making for differentiating malignant from benign lesions in the gallbladder remains challenging. We aimed to create a diagnostic nomogram to identify gallbladder cancer (GBC), especially for incidental GBC (IGBC), before surgical resection.

Methods: A total of 587 consecutive patients with pathologically confirmed gallbladder lesions from a hospital were randomly assigned to a training cohort (70%) and an internal validation cohort (30%), with 287 patients from other centers as an external validation cohort.

Surgical outcomes of two-stage hepatectomy for colorectal liver metastasis: comparison to a benchmark procedure.

Background: Two-stage hepatectomy (TSH) with portal vein embolization (PVE) is associated with high morbidity and mortality and may result in liver failure due to insufficient future liver remnant. The objectives of this investigation were to evaluate the short-term outcomes of patients with colorectal cancer liver metastasis who underwent TSH with PVE, and to critically review the selection criteria for TSH-PVE.

Methods: A retrospective review of all patients who were operated due to bi-lobar CRLM during the years 2007-2017 was performed.

Open Repair of Hepatic Artery and Celiac Artery Aneurysms in a Patient With Prior Aortic Dissection With an Iliac to Hepatic Artery Bypass.

A 67-year-old male with a history of an aortic dissection was found to have a large hepatic and celiac artery aneurysm. Due to the extent of the dissection within the aorta, a bypass was performed from his iliac artery to the hepatic bifurcation, followed by exclusion and ligation of the aneurysms.

Major hepatectomy for complex liver trauma.

The liver is the most frequently injured intraperitoneal organ, despite its relatively protected location. The liver consisting of a relatively fragile parenchyma contained within the Glisson capsule, which is thin and does not provide it with great protection. The management of hepatic trauma has undergone a paradigm shift over the past several decades with significant improvement in outcomes.

Diffusion tensor magnetic resonance imaging of the pancreas.

Purpose: To develop a diffusion-tensor-imaging (DTI) protocol that is sensitive to the complex diffusion and perfusion properties of the healthy and malignant pancreas tissues.

Materials And Methods: Twenty-eight healthy volunteers and nine patients with pancreatic-ductal-adenocacinoma (PDAC), were scanned at 3T with T2-weighted and DTI sequences. Healthy volunteers were also scanned with multi-b diffusion-weighted-imaging (DWI), whereas a standard clinical protocol complemented the PDAC patients' scans.

Ciliated hepatic foregut cyst with high intra-cystic carbohydrate antigen 19-9 level.

A ciliated hepatic foregut cyst (CHFC) is a rare foregut developmental malformation usually diagnosed in adulthood. Five percent of reported cases of CHFC transform into squamous cell carcinoma. We report the presentation, evaluation, and surgical management of a symptomatic 45-year-old male found to have a 6.

Complications after percutaneous ablation of liver tumors: a systematic review.

Background: Although ablation therapy has been accepted as a promising and safe technique for treatment of unrespectable hepatic tumors, investigation of its complications has been limited. A physician who performs ablation treatment of hepatic malignancies should be aware of the broad spectrum of complications. Proper management is possible only if the physician Performing ablation understands the broad spectrum of complications encountered after ablation.

Small for size liver remnant following resection: prevention and management.

In the latest decades an important change was registered in liver surgery, however the management of liver cirrhosis or small size hepatic remnant still remains a challenge. Currently post-hepatectomy liver failure (PLF) is the major cause of death after liver resection often associated with sepsis and ischemia-reperfusion injury (IRI). ''Small-for-size'' syndrome (SFSS) and PFL have similar mechanism presenting reduction of liver mass and portal hyper flow beyond a certain threshold.

"Vanishing liver metastases"-A real challenge for liver surgeons.

Expanded surgical intervention in colorectal liver metastasis (LM) and improved chemotherapy led to increasing problem of disappearing liver metastases (DLM). Treatment of those continues to evolve and poses a real challenge for HPB surgeons. This review discusses a clinical approach to DLM, emphasizing crucial steps in clinical algorithm.

Cellularized biosynthetic microhydrogel polymers for intravascular liver tissue regeneration therapy.

Introduction: The liver is the natural microenvironment for hepatocytes transplantation but unfortunately engraftment efficiency is low. Cell-laden microhydrogels made of fibrinogen attached to poly(ethylene glycol) (PEG)-diacrylate side chains, were used as a cell carrier, for intravascular transplantation. This approach may reduce shear stress and immediate immunological pressure after intravascular transplantation and provide biomatrix for environmental support.

Portal vein arterialization: a salvage procedure for a totally de-arterialized liver. The Paul Brousse Hospital experience.

Background: Portal vein arterialization (PVA) has been used as a salvage inflow technique when hepatic artery (HA) reconstruction is deemed impossible in liver transplantation (LT) or hepatopancreatobiliary (HPB) surgery. Outcomes and the management of possible complications have not been well described.

Methods: The present study analysed outcomes in 16 patients who underwent PVA during the period from February 2005 to January 2011 for HA thrombosis post-LT (n = 7) or after liver resection (n = 1), during curative resection for locally advanced HPB cancers (requiring HA interruption) (n = 7) and for HA resection without reconstruction (n = 1).

Short- and long-term results of extended left hepatectomy for colorectal metastases.

Background: An extended left hepatectomy is a complex hepatic resection often performed for large tumours in close relationship to major hilar structures. Operative outcomes of this resection for colorectal liver metastases (CLM) remain unclear. The aim of the present study was to assess short- and long-term outcome for patients with CLM after an extended left hepatectomy.

Exposure during pancreatic surgery. Do we have to examine the falciform and round ligaments for pancreatic cancer metastasis?

Context: Metastatic and locally advanced disease is unfortunately a common clinical occurrence in patients affected by pancreatic cancer. The most frequent sites of metastasis are the liver and the peritoneal lining. The falciform and round ligaments are routinely resected and sent for pathology, but no metastases have ever been reported.

Phase II study of UFT with leucovorin plus hepatic arterial infusion with irinotecan, 5-fluorouracil and leucovorin for non-resectable liver metastases of colorectal cancer.

Background: Compared with systemic therapy, hepatic arterial infusion (HAI) increases the response to fluoropyrimidines.

Methods: Thirty-one patients with non-resectable, colorectal cancer (CRC) liver metastases received irinotecan 120 mg/m(2), followed by leucovorin (LV) 20 mg/m(2) and 5-fluorouracil (5-FU) 500 mg/m(2) administered by HAI every 2 weeks, plus UFT (tegafur-uracil) 200 mg/m(2)/day with LV 30 mg/day on days 1-22, followed by a 6-day rest.

Results: The objective response rate was 65% (all 20 patients achieving a partial response).

Mid-term results of stapled hemorrhoidopexy for third- and fourth-degree hemorrhoids--correlation with the histological features of the resected tissue.

Background: Stapled hemorrhoidopexy is used to remove a circumferential strip of mucosa and submucosa about 4 cm above the dentate line, in order to restore the correct anatomical relationships of the anal canal structures. We evaluated the histological features of the resected tissue obtained after stapled hemorrhoidopexy with correlation to the short-term and mid-term results.

Methods: This retrospective study evaluated 234 cases of stapled hemorrhoidopexy.

Treatment of large incisional abdominal wall hernias, using a modified preperitoneal prosthetic mesh repair.

Very large and complex incisional hernias, especially those with loss of abdominal wall, can be a very interesting and perplexing problem, which present a particular challenge to the surgeon. The reported technique was developed and refined by one of our surgeons, between 1998 and 1999 for the repair of incisional hernias in a selected group of patients with large defects, often with a major loss of abdominal wall, overweight and previous attempts for incisional hernia repair. The technique involves a modified preperitoneal approach and was used on 43 eligible patients between 1999 and 2002.

Five-year survival following hepatic resection after neoadjuvant therapy for nonresectable colorectal.

Background: Surgical resection is the most effective treatment for colorectal liver metastases but only a minority of patients are candidates for a potentially curative resection. Our experience with neoadjuvant chemotherapy followed by resection and five years survival analysis of the patients treated is presented.

Methods: Between February of 1988 and September of 1996, 701 patients with unresectable colorectal liver metastases were treated with neoadjuvant chemotherapy.

Gastric outlet obstruction by gallstone: Bouveret syndrome.

Gallstone has rarely been described as a cause of gastrointestinal obstruction. However, the relative incidence of gallstone ileus increases significantly with age. The gastric outlet is very seldom the location of obstruction by a gallstone.

[Acute ischemia of the lesser gastric curvature--a rare marker of sclerotic disease].

The rich blood supply of the stomach protects it from ischemia and necrosis. Acute gastric ischemia, an emergency with high mortality, is rare. Atherosclerosis is the leading cause of acute ischemia, and the lesser curvature of the stomach is more vulnerable due to its relatively lesser blood supply.
