With the accumulation of experience in laparoscopic radical gastrectomy and the progress in surgical instruments, the laparoscopic technique has been widely applied in gastric cancer. Combining previous reports with data from our center, we believe that laparoscopic surgery for gastric cancer is safe and feasible, and its surgery-related complications have an incidence that is not higher, and perhaps even lower, than that of traditional laparotomy. However, the stomach has many anatomical levels and an abundant blood supply; additionally, laparoscopic surgery is relatively difficult...

CASE REPORT: Cystic urolithiasis is the most common form of urolithiasis reported in horses. In contrast to the gelding or stallion, clinical disease is less common in the mare and manual removal techniques are possible because of their shorter, wider urethral anatomy. However, these manual removal techniques can be traumatic and are limited by the size of the urolith. This report describes the use of a commercial laparoscopic specimen pouch to remove a cystic urolith in a mare. CONCLUSION: This approach may allow the extraction of larger uroliths per urethra in the mare, while affording some protection to the mucosa of the bladder neck and urethra...

Internal hernia is a rare cause of bowel obstruction which often requires emergent surgery. In general, the preoperative diagnosis of internal hernia is difficult. The pelvic cavity has various spaces with the potential to result in a hernia, especially in females. In this report, we describe a patient with an internal hernia secondary to previous gynecologic surgery. A 49-year-old woman presented with acute abdominal pain and a history of previous right oophorectomy for a benign ovarian cyst. Computed tomography scan of the abdomen showed obstruction with strangulation and emergent laparoscopic exploration was performed...

Posterior retroperitonoscopic adrenalectomy (PRA) has become a standard approach to the adrenal gland. The aim of this study was to report an initial experience with the procedure following a proper preparatory phase highlighting the rapidity, safety and effectiveness by which it could be introduced into a surgeon's practice. Between May 2015 and July 2016, 14 PRAs were performed in 14 patients (9 females and 5 males). The average age was 46 years, BMI: 25.5 kg/m(2), and ASA score: 2. Indications included: incidenatloma (n = 5), Conn's adenoma (n = 5), and Cushing's adenoma (n = 4)...

BACKGROUND Gallbladder agenesis (GA) is an extremely rare anatomic anomaly with a reported incidence of less than 0.5%. It is usually asymptomatic, but can present with features of biliary colic and cholecystitis. We present here a case of GA in a patient with recurrent biliary colic.  CASE REPORT A 24-year-old African American woman presented with recurrent episodes of right upper-quadrant abdominal pain. During her first episode, she was found to have elevated transaminases and clinical features of cholecystitis, but ultrasound did not visualize a gallbladder and she was discharged with a diagnosis of biliary colic...

We sought to determine the feasibility of developing a multimedia educational tutorial to teach learners to assess the critical view of safety using input from expert surgeons, non-surgeons and crowd-sourcing. We intended to develop a tutorial that would teach learners how to identify the basic anatomy and physiology of the gallbladder, identify the components of the critical view of safety criteria, and understand its significance for performing a safe gallbladder removal. Using rounds of assessment with experts, laypersons and crowd-workers we developed an educational video with improving comprehension after each round of revision...

In spite of the fact that urologic surgical techniques used by urologists are becoming more and more minimally invasive and easier because of developing technologies, surgical approaches for the urinary stones in kidneys with abnormal anatomy are still confusing. The objective of this article is to determine the treatment options in these kidneys. For this purpose, between 2005 and 2015, we retrospectively evaluated patients operated for urolithiasis with various congenital renal anomalies in five referral urology clinics in our country...

OBJECTIVES: During laparoscopic-assisted colorectal surgery (LACS), precise recognition of the anatomic variations and relationships among tumor and vessels is required. However, in highly obese patients, it is more difficult to grasp the surgical anatomy due to the presence of dense mesenteric fat tissue. We utilized a 3-dimensional (3D) reconstructed image for preoperative simulation and intraoperative navigation for LACS. In this study, we examined the correlation between patient obesity and 3D-simulated perioperative outcomes...

INTRODUCTION: Surgery for the difficult gallbladder (DGB) is associated with increased risk compared to more routine laparoscopic cholecystectomies (LC). Laparoscopic "damage control" methods including cholecystostomy, fundus-down approach and subtotal cholecystectomy (SC) have been proposed to avoid conversion to open. We hypothesized that a Total LC (TLC) for DBG can be completed safely with an acceptably low conversion rate. MATERIAL AND METHODS: All patients that underwent LC from January 2005-June 2015 were retrospectively reviewed...

INTRODUCTION: Laparoscopic donor nephrectomy is widely used to retrieve a kidney for transplantation. Preoperative evaluation of the donor is of crucial importance to the recipient. In particular, vascular anatomy should be assessed with the help of modern imaging modalities. We present a hand-assisted laparoscopic nephrectomy of a kidney donor with a complete duplex vena cava. CASE REPORT: A 40-year-old male patient was admitted to our clinic as a kidney donor for his 20-year-old son...

Balloon-assisted endoscopic retrograde cholangiopancreatoscopy (ERCP) in Roux-en-Y gastric bypass (RYGB) patients is technically challenging due to anatomic and accessory constraints, thus success rates are modest. Transgastric ERCP (TG-ERCP) offers a viable alternative. We aimed to systematically review the literature on TG-ERCP in RYGB patients to better define the technical approaches, success rates, and adverse events of this procedure. A computer-assisted search of the Embase and PubMed databases was performed to identify studies that focused on the techniques and clinical outcomes of TG-ERCP...

Liver hanging maneuver (LHM) is an important technique in liver surgery. However, applied anatomy of the retrohepatic tunnel for the surgical approach in Chinese population needs further study. In this study, to explore the basic anatomy of retrohepatic tunnel and its clinical application in a Chinese population, a total of 32 formalin-fixed cadavers were dissected, related parameters were measured, and their clinical applications were discussed. The length of the retrohepatic tunnel was (60.6 ± 9.9) mm...

INTRODUCTION: One anastomosis gastric bypass (OAGB) demonstrated results similar to traditional Roux-en-Y procedures [1-3], in terms of weight loss and resolution of obesity-related comorbidities. The main controversy regarding OAGB is the concern for an association between biliary alkaline gastritis and esophageal or gastric cancer raised by some studies [4]. METHODS: We present the case of a 51-year-old woman with a BMI of 41 kg/m2 who underwent a laparoscopic OAGB in 2014...

BACKGROUND: Biliary pancreatitis (BP) constitutes 30-55% of all cases of acute pancreatitis. Laparoscopic cholecystectomy (LC) has become the gold standard for the surgical treatment of gallbladder disease. We aimed to compare and evaluate the relation between the timing of LC and the rates and reasons of conversion to open surgery (OS) after BP. METHODS: Data were collected of patients who presented for the first time with acute BP and underwent LC. The patients were divided into two groups: early cholecystectomy (Group 1), patients who underwent cholecystectomy during the first pancreatitis attack upon admission and before discharge from hospital (1-3 days); and late cholecystectomy (Group 2), patients who received medical treatment during their first pancreatitis episode and underwent surgery after 4-10 weeks...

BACKGROUND: Evidence suggests that Mental Practice (MP) could be used to finesse surgical skills. However, MP is cognitively demanding and may be dependent on the ability of individuals to produce mental images. In this study, we hypothesised that the provision of interactive 3D visual aids during MP could facilitate surgical skill performance. METHODS: 20 surgical trainees were case-matched to one of three different preparation methods prior to performing a simulated Laparoscopic Cholecystectomy (LC)...

Anatomical variations of the hepatic arteries are not uncommon. The anomalous hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic or liver transplantation and in laparoscopic surgery. We describe an unusual case of a 66-year-old Greek male cadaver, where a rare anastomosis (in the form of an enlarged arterial loop, 4.84 mm in diameter) between the common hepatic artery (6.42 mm) and the gastroduodenal artery (GDA) (4.82 mm) coexisted with an aberrant right hepatic artery (ARHA) (6...
