Case report: A ERBB3 mutation develops in a gallbladder cancer patient carrying BRCA1 mutation after effective treatment with olaparib.

Background: Gallbladder cancer (GBC) is highly lethal and resistant to most chemotherapeutic drugs. GBC was reported to carry multiple genetic mutations such as TP53, K-RAS, and ERBB2/3. Here, we unexpectedly identified a patient with GBC harboring germline BRCA1 p.

Patient-centered developments in colon- and rectal cancer with a multidisciplinary international team: From translational research to national guidelines.

Rarely, scientific developments centered around the patient as a whole are published. Our multidisciplinary group, headed by gastrointestinal surgeons, applied this research philosophy considering the most important aspects of the diseases "colon- and rectal cancer" in the long-term developments. Good expert cooperation/knowledge at the Comprehensive Cancer Center Ulm (CCCU) were applied in several phase III trials for multimodal treatments of primary tumors (MMT) and metastatic diseases (involving nearly 2000 patients and 64 centers), for treatment individualization of MMT and of metastatic disease, for psycho-oncology/quality of life involving the patients' wishes, and for disease prevention.

Pancreatogastrostomy pancreatojejunostomy after pancreaticoduodenectomy: An updated meta-analysis of RCTs and our experience.

Background: Pancreatoduodenectomy (PD) is one of the most important operations in hepatobiliary and pancreatic surgery.

Aim: To evaluate the advantages and disadvantages of pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG).

Methods: This meta-analysis was performed using Review Manager 5.

Better surgical treatment method for hepatocellular carcinoma with portal vein tumor thrombus.

Hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is a disease that is not uncommon, but the treatments vary drastically between Eastern and Western countries. In Europe and America, the first line of treatment is systemic therapy such as sorafenib and the surgical treatment is not a recommend option. While an increasing number of studies from China and Japan have suggested that surgical treatment results in better outcomes when compared to transcatheter arterial chemoembolization (TACE), sorafenib, or other nonsurgical treatments, and two classification systems, Japanese Vp classification and Chinese Cheng's classification, were very useful to guide the surgical treatment.

Anatomic isolated caudate lobectomy: Is it possible to establish a standard surgical flow?

Aim: To establish the surgical flow for anatomic isolated caudate lobe resection.

Methods: The study was approved by the ethics committee of the Second Affiliated Hospital Zhejiang University School of Medicine (SAHZU). From April 2004 to July 2014, 20 patients were enrolled who underwent anatomic isolated caudate lobectomy at SAHZU.

Evolution of associating liver partition and portal vein ligation for staged hepatectomy: Simpler, safer and equally effective methods.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been recently demonstrated as a method to induce rapid and extensive hypertrophy within a short time and has been employed for a variety of primary and metastatic liver tumors. However, controversies remain due to its high morbidity and mortality. To enable safer surgery, liver surgeons have searched for better technical modifications, such as partial ALPPS, mini-ALPPS, minimally invasive ALPPS, and Terminal branches portal vein Embolization Liver Partition for Planned hepatectomy (TELPP).

Identification of serologic biomarkers for predicting microvascular invasion in hepatocellular carcinoma.

Microvascular invasion (MVI) of hepatocellular carcinoma (HCC) is a major risk factor for early recurrence and poor survival after curative surgical therapies. However, MVI can only be diagnosed by pathological examination following resection. The aim of this study is to identify serologic biomarkers for predicting MVI preoperatively to help facilitate treatment decisions.

Management of hepatocellular carcinoma rupture in the caudate lobe.

Aim: To demonstrate that caudate lobectomy is a valid treatment in cases of hepatocellular carcinoma (HCC) rupture in the caudate lobe based on our experience with the largest case series reported to date.

Methods: A retrospective study of eight patients presenting with spontaneous rupture and hemorrhage of HCC in the caudate lobe was conducted. Two patients underwent ineffective transarterial embolization preoperatively.

Local delivery of vascular endothelial growth factor via nanofiber matrix improves liver regeneration after extensive hepatectomy in rats.

Vascular endothelial growth factor (VEGF) is a potent regulator for liver regeneration following partial hepatectomy. However, intravenous delivery of VEGF has yielded limited success in promoting the regeneration of remnant liver. Here we report a new approach to locally deliver recombinant VEGF from an electrospun poly-ε-caprolactone nanofiber mesh and its effect on improving rat liver regeneration after 70% hepatectomy.

Completely laparoscopic ALPPS using round-the-liver ligation to replace parenchymal transection for a patient with multiple right liver cancers complicated with liver cirrhosis.

The "ALPPS" (associating liver partition with portal vein ligation for staged hepatectomy) procedure enables the rapid growth of the future liver remnant and extended surgical indication to patients with an "insufficient" future liver remnant. In May 2014, a 64-year-old male patient was admitted. The computed tomography (CT) scan showed multiple right liver lesions, which were diagnosed to be hepatocellular carcinoma by liver biopsy.

[The role of preoperative TACE on hepatocellular carcinoma located in caudate lobe].

Objective: To evaluate the effect of preoperative transarterial chemoembolization (TACE) on hepatocellular carcinoma located in caudate lobe.

Methods: Totally 29 cases of caudate lobe hepatocellular carcinoma admitted from January 2001 to December 2010 were analyzed retrospectively. Among the 29 patients, 23 were male and the other 6 were female.

"Total arterial devascularization first" technique for resection of pancreatic head cancer during pancreaticoduodenectomy.

Integrated resection of the pancreatic head is the most difficult step in radical pancreaticoduodenectomy (RPD) in patients with the portal vein (PV) and superior mesenteric vein (SMV) invasion or oppression by the tumor. This study introduced a new idea and skill named the "total arterial devascularization first" (TADF) technique and its applications in RPD. Three arterial blood supplies of pancreatic head were obstructed before dissection of veins.

Mucoepidermoid carcinoma of the pancreas: a case report and a review of literature.

Mucoepidermoid carcinoma of the pancreas is rare. Here, a 63-year-old woman with left upper abdominal pain and abdominal distension is presented. Her mucoepidermoid carcinoma was located at the left upper abdomen, arising from the pancreatic body and tail without invasion of pancreatic capsule.

Intrahepatic biliary cystadenoma presenting with pleural effusion.

Hepatobiliary cystadenomas are rare cystic neoplasms that often occur in middle aged women. The exact etiology of these tumors is unknown. Diagnosis is often delayed in these cases.

[Binding pancreatic duct to mucosa anastomosis].

Objective: To study the feasibility of binding pancreatic duct to mucosa anastomosis (BDM)-a complementary procedure to both binding pancreaticojejunostomy and binding pancreaticogastrostomy.

Methods: (1) Animal experimental study:gastrostomy and jejunostomy were performed on six adult New Zealand rabbits. The gastrostomy and jejunostomy shared a same stent (rubber urethral catheter, silicone tube or plastic infusion tube).

Binding pancreaticoenteric anastomosis: from binding pancreaticojejunostomy to binding pancreaticogastrostomy.

Potential mechanisms of occurrence of pancreatic leakage mainly include leakage from the needle hole and from the seam at the adjacent stitch, anastomotic blood supply, tension at the anastomosis, poor anastomotic healing, etc. Binding pancreaticojejunostomy (BPJ) is a safe and effective technique that avoids the primary complication of pancreatic anastomosis leakage. There are two problems with BPJ: a high discrepancy in the size of pancreas stump and the jejunal lumen; sutures on to the pancreas for fixation might cause exudation of pancreatic juice into the abdominal cavity.

[A pancreas suture-less type II binding pancreaticogastrostomy].

Objective: To explore the feasibility and safety of type II binding pancreaticogastrostomy (BPG) in pancreaticoduodenectomy and mid-segmentectomy of pancreas.

Methods: From November 2008 to May 2009, 26 patients underwent pancreaticoduodenectomy and mid-segmentectomy of pancreas with type II BPG reconstruction, including 13 cases of pancreatic head cancer, 3 cases of duodenal adenocarcinoma, 2 cases of ampullary carcinoma, 4 cases of cholangiocarcinoma, 1 case of bile duct cell severe atypical hyperplasia, and 1 case of stomach cancer. The process of type II BPG was described as the following: after pancreas remnant was mobilized for 2-3 cm, a piece of sero-muscular layer at the posterior gastric wall was excised and then a sero-muscular depth purse-suturing with 3-0 prolene was pre-placed (outer purse-string).

[Binding pancreaticogastrostomy].

Objective: To discuss the value of a new technique of the binding pancreaticogastrostomy (BPG) in pancreaticoduodenectomy.

Methods: From May 2008 to October 2008, 15 patients were performed with BPG, included pancreatic head cancer in 7 cases, duodenal adenocarcinoma in 2 cases,mass-type chronic pancreatitis with pancreatolithiasis in 1 case, ampullary carcinoma in 1 case, gallbladder cancer in 1 case, islet cell tumor in 1 case and cholangiocarcinoma in 2 cases. The main procedures of BPG included: isolating remnant pancreas; slitting partial posterior wall of stomach and preplaced with seromuscular purse-string suture; cutting gastric anterior wall; performing pancreaticogastrostomy (binding of outer seromuscular and inner mucous layer of stomach).
