A novel difficulty scoring system for laparoscopic liver resection.
J Hepatobiliary Pancreat Sci

Show Abstract
Hide Abstract
Early on, laparoscopic liver resection (LLR) was limited to partial resection, but major LLR is no longer rare. A difficulty scoring system is required to guide surgeons in advancing from simple to highly technical laparoscopic resections. Subjects were 90 patients who had undergone pure LLR at three medical institutions (30 patients/institution) from January 2011 to April 2014. Surgical difficulty was assessed by the operator using an index of 1-10 with the following divisions: 1-3 low difficulty, 4-6 intermediate difficulty, and 7-10 high difficulty. Weighted kappa statistic was used to calculate the concordance between the operators' and reviewers' (expert surgeon) difficulty index. Inter-rater agreement (weighted kappa statistic) between the operators' and reviewers' assessments was 0.89 with the three-level difficulty index and 0.80 with the 10-level difficulty index. A 10-level difficulty index by linear modeling based on clinical information revealed a weighted kappa statistic of 0.72 and that scored by the extent of liver resection, tumor location, tumor size, liver function, and tumor proximity to major vessels revealed a weighted kappa statistic of 0.68. We proposed a new scoring system to predict difficulty of various LLRs preoperatively. The calculated score well reflected difficulty.

Diabetes with preserved renal function is an independent risk factor for renal function deterioration after coronary computed tomography angiography.

Hide Abstract
Diabetes mellitus (DM) and high fasting glucose levels are reportedly risk factors for contrast-induced nephropathy after invasive coronary angiography in patients with renal dysfunction. Cystatin C (CyC) is a sensitive marker for detecting early impairment of renal function. Using CyC, we investigated whether DM would be a risk for worsening renal function after coronary computed tomography angiography (CCTA) in patients with preserved renal function.

Gas embolism in laparoscopic hepatectomy: what is the optimal pneumoperitoneal pressure for laparoscopic major hepatectomy?
J Hepatobiliary Pancreat Sci
PUBLISHED: 08-07-2013
Show Abstract
Hide Abstract
Laparoscopic hepatectomy (LH) has become popular as a surgical treatment for liver diseases, and numerous recent studies indicate that it is safe and has advantages in selected patients. Because of the magnified view offered by the laparoscope under pneumoperitoneal pressure, LH results in less bleeding than open laparotomy. However, gas embolism is an important concern that has been discussed in the literature, and experimental studies have shown that LH is associated with a high incidence of gas embolism. Major hepatectomies are done laparoscopically in some centers, even though the risk of gas embolism is believed to be higher than for minor hepatectomy due to the wide transection plane with dissection of major hepatic veins and long operative time. At many high-volume centers, LH is performed at a pneumoperitoneal pressure less than 12 mmHg, and reports indicate that the rate of clinically severe gas embolism is low. However, more studies will be necessary to elucidate the optimal pneumoperitoneal pressure and the incidence of gas embolism during LH.

Transesophageal endoscopic myotomy (TEEM) for the treatment of achalasia: the United States human experience.

Hide Abstract
From our early experience with NOTES, our group has acquired familiarity with transesophageal submucosal dissection and myotomy in swine model, which allowed us to perfect a model to perform purely endoscopic transesophageal myotomy (TEEM) for the treatment of achalasia and apply it into clinical practice. This study was designed to assess the safety, feasibility, and efficacy of TEEM in a series of patients with achalasia.

Broad clinical utilization of NOTES: is it safe?

Hide Abstract
Natural orifice transluminal endoscopic surgery (NOTES) has been the focus of several studies as a less invasive alternative to conventional laparoscopy to access and treat intracavitary organs. For the last 5 years, much has been accomplished with animal studies, yet the clinical utilization of this novel technique is still modest. After 2 years of experience in the laboratory, we started our clinical experience. We report our experience with clinical utilization of NOTES procedures from 2007 to 2010.

To examine feasibility of transrectal hybrid natural orifice translumenal endoscopic surgery (NOTES) nephrectomy in the porcine model. NOTES uses ports of entry to the peritoneal cavity instead of abdominal wall incisions, thereby eliminating visible scar and also potentially reducing postoperative pain.

[Patterns causing hepatic arterial inner wall injury by catheter insertion-from a case in which catheter probe patency was confirmed 65 months after implant].

Hide Abstract
We experienced a case in which the hepatic artery catheter system could be used long term. Even after 5 years and five months, there was no damage to the hepatic artery, and we could still use this system. For insertion of the catheter, a fine catheter with the tip tapered at 2.7 F was selected. This catheter was inserted into the hepatic artery peripheral branch in the liver, after a side hole was created 11 cm from the tip, and the side hole was adjusted to stay in the common hepatic artery. We speculated that the reason for little injury to the hepatic artery was use of a fine catheter despite possible damage to the hepatic artery wall like saw cutting in this case. We classified the patterns according to which a catheter damaged the inner wall of the hepatic artery into 5: "straight punch type", "hook punch type", "whiplash type", "elbow blow type", "and saw type".

[Laparoscopic surgery for pancreatic cancer].

Show Abstract
Hide Abstract
Laparoscopic distal pancreatectomy is currently in widespread use because of its technical simplicity, although laparoscopic pancreaticoduodenectomy is practiced in only a limited number of surgical institutions due to the associated technical difficulties especially at reconstruction. The indication for the treatment of pancreatic cancer by a laparoscopic procedure remains controversial. Because pancreatic cancer is already advanced at the time of diagnosis in many cases, it requires a difficult radical operation in terms of lymphadenectomy with nerves plexus in laparoscopic surgery. The oncologic clearance of pancreatic resection may be achievable by laparoscopic surgery, although longer follow-up and larger series of treatment are still needed.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
