BACKGROUND: An internal abdominal hernia is defined as the protrusion of a viscus through a mesenteric or peritoneal aperture within the peritoneal cavity. A less common type of internal herniation is a small bowel herniation through a defect in the falciform ligament of the liver. This defect can be congenital or iatrogenic after penetration of the falciform ligament with a trocar during laparoscopic surgery. METHODS: We present a case report illustrating an internal herniation through an iatrogenic defect in the falciform ligament of the liver...

BACKGROUND: Even if the jejunoileal bypass has been definitely abandoned due to the high rate of hepatic complications, cases of liver injury after the new bariatric procedures are still reported. We aimed to review the available literature concerning liver damage associated with the older and newer types of bariatric surgeries. METHODS: An extensive literature search of MEDLINE was performed using different combinations of the following terms: "bariatric surgery OR biliopancreatic diversion OR jejunoileal bypass OR roux-en-y gastric bypass OR vertical banded gastroplasty OR laparoscopic adjustable gastric banding" AND "hepatic/liver damage OR hepatic/liver impairment OR hepatic/liver failure"...

INTRODUCTION: The gold standard treatment for hydatid cyst (HC) is surgery. In surgical practice, open procedures still remain as the first option but in this minimally-invasive era, the frequency of laparoscopic procedures is increasing. The aim of this study is to evaluate the results of 42 patients with HC who underwent surgery with Perforator-Grinder-Aspirator-Apparatus (PGAA) and demonstrate the success and reliability of this technique. METHODS: The datas of 42 patients, who underwent laparoscopic surgery with PGAA between Jan 2010 and Feb 2016 were evaluated retrospectively...

Introduction Laparoscopic cholecystectomy (LC) is the most commonly done, minimally invasive surgical procedure. Routinely used electrocautery produces more smoke, which masks the operating field, thereby prolongs the surgery and posing an increased risk of gallbladder (GB) perforation. The titanium clips used for clipping the cystic artery and cystic duct have a risk of slippage, which may lead to bleeding, and an increased risk for bile leakage. In addition, it may act as a nidus for stone formation. Advanced energy sources, such as the harmonic scalpel, though expensive, may provide the advantage of shorter operating time by reducing smoke, bloodless dissection in the GB bed, lower risk of bleeding from the cystic artery due to secure vessel sealing, and avoiding the use of a larger number of titanium clips...

BACKGROUND: Despite potential benefits of robotic liver surgery, it is still considered a "development in progress" technique. METHODS: The outcomes of 14 patients undergoing robotic right hepatectomy were analyzed and compared with the results of 20 laparoscopic right hepatectomies consecutively performed by the same young surgeon. RESULTS: The overall mean operative time was less in robotic arm (425 ± 139 vs. 565.18 ± 183.73, p = 0...

Adrenal pseudocysts are rare entities, which are usually asymptomatic. Large symptomatic adrenal pseudocysts may cause compressive symptoms. The etiology of these cysts is unknown, although the cyst wall is all lined by fibrous tissue, without any epithelial or endothelial lining. We report a case of a 26-year-old lady who presented with a symptomatic right adrenal pseudocyst measuring 7.6 cm in size. Magnetic resonance imaging confirmed the presence of a right retroperitoneal cystic lesion which was hyperintense on T2 sequencing...

The application of laparoscopy for liver surgery is rapidly increasing and the past few years have demonstrated a shift in paradigm with a trend towards more extended and complex resections. The development of instruments and technical refinements with the effective use of magnified caudal laparoscopic views have contributed to the ability to overcome the limitation of laparoscopic liver resection. The Endoscopic and Laparoscopic Surgeons of Asia (ELSA) Visionary Summit 2017 and the 3rd Expert Forum of Asia-Pacific Laparoscopic Hepatectomy organized hepatobiliary pancreatic sessions in order to exchange surgical tips and tricks and discuss the current status and future perspectives of laparoscopic hepatectomy...

We propose a novel method to simulate soft tissue deformation for virtual surgery applications. The method considers the mechanical properties of soft tissue, such as its viscoelasticity, nonlinearity and incompressibility; its speed, stability and accuracy also meet the requirements for a surgery simulator. Modifying the traditional equation for mass spring dampers (MSD) introduces nonlinearity and viscoelasticity into the calculation of elastic force. Then, the elastic force is used in the constraint projection step for naturally reducing constraint potential...

BACKGROUND: When a major hepatic resection is necessary, sometimes the future liver remnant is not enough to maintain sufficient liver function and patients are more likely to develop liver failure after surgery. AIM: To test the hypothesis that performing a percutaneous radiofrecuency liver partition plus percutaneous portal vein embolization (PRALPPS) for stage hepatectomy in pigs is feasible. METHODS: Four pigs (Sus scrofa domesticus) both sexes with weights between 25 to 35 kg underwent percutaneous portal vein embolization with coils of the left portal vein...

Liver resection is the standard treatment for any liver lesion. Laparoscopic liver resection is associated with lower intra-operative blood loss and fewer complications than open resection. Access to the posterior part of the right liver lobe is very uncomfortable and difficult for surgeons due the anatomic position, especially when employing laparoscopic surgery. Based on these experiences, a new laparoscopic device was developed that is capable of bending its long axis and allowing the application of radiofrequency energy in areas that were not technically accessible...

RATIONALE: Cystic echinococcosis (CE) is a parasitic zoonosis caused by echinococcus larvae. Manifestations of the disease include a severe damage to the liver and lung. Damages to the mesentery, omentum, spleen, brain, heart, bone, thyroid, kidney, and uterus are rarely observed. Moreover, primary ovarian and retroperitoneal hydatid disease is extremely rare, and is easily ignored or misdiagnosed. PATIENT CONCERNS: We present a case of CE in a 34-year-old female who presented with an adnexal mass detected by B-ultrasound...

PURPOSE: Image guidance is a key technology that can improve the outcome of laparoscopic surgery. However, due to the large deformation caused by digestive organs, a computer-aided navigation system based on preoperative imaging data cannot indicate the correct target position of the lesion (e.g., liver tumors and vessels invisible from the organ surface). To overcome this issue, we developed a laparoscopic ultrasound manipulator with two motorized degrees of freedom at the tip, allowing for the performance of a dexterous ultrasound scan in a confined laparoscopic surgical area...

Patent ductus venosus (PDV) is an uncommon but important congenital portocaval shunt that can lead to numerous complications if untreated. This case describes the successful management of a 17-year-old male with symptomatic PDV. Doppler ultrasonography and contrast-enhanced computed tomography (CT) confirmed a large communication between the left portal vein and the inferior vena cava. Angiography demonstrated a large and high flow PDV which precluded its therapeutic embolization. Based on these findings, laparoscopic closure of the PDV was elected and successfully performed...

The standard therapy for Stage IV gastric cancer is chemotherapy. It is not certain, but conversion surgery is expected to be effective. We report the cases of 3 patients who achieved long-term survival after conversion surgery. Case 1 was of a 59- year-old woman. The tumor was classified as L-Less Post, Type 2, tub1, cT3N2M1(#16a2lat), Stage IV. Then, we initiated S-1 plus cisplatin and the LN achieved PRafter 4 courses. We performed distal gastrectomy with D2 lymph node dissection in February 2011. It was classified as ypT2N2 and the primary lesion was histologically classified as Grade 1a...
