The training courses of urological laparoscopy is written by an international team of experts who have come together to share their experiences of training and skills acquisition in Urological Laparoscopy. Skills training and certification are needed to protect both patient and doctor from the pitfalls of uncertified practice. This comprehensive text focuses on the details of laparoscopic training within the field of urology from step-by-step guidance on the use of basic stems in the dry lab through to hints and tricks for problem solving in more complex scenarios.

ABSTRACT
Purpose: Postoperative pneumonia affects the length of stay and mortality after surgery in elderly patients with colorectal cancer (CRC). We aimed to determine the risk factors of postoperative pneumonia in elderly patients with CRC, and to evaluate the impact of laparoscopic surgery on elderly patients with CRC. Methods: We retrospectively investigated 1473 patients ≥ 80 years of age who underwent surgery for stage 0-III CRC between 2003 and 2007. Using a multivariate analysis, we determined the risk factors for pneumonia occurrence from each baseline characteristic. Results: Among all included patients, 26 (1.8%) experienced postoperative pneumonia, and restrictive respiratory impairment, obstructive respiratory impairment, history of cerebrovascular events, and open surgery were determined as risk factors (odds ratio [95% confidence interval], 2.78 [1.22-6.20], 2.71 [1.22-6.30], 3.60 [1.37-8.55], and 3.57 [1.22-15.2], respectively). Furthermore, postoperative pneumonia was more frequently accompanied by increasing cumulative numbers of these risk factors (area under the receiver operating characteristic curve = 0.763). Conclusions: Laparoscopic surgery may be safely performed in elderly CRC patients, even those with respiratory impairment and a history of cerebrovascular events.

Purpose: We developed a microwave energy-based scissors device (MWCX) that is capable of performing cutting and coagulation using 2.45 GHz microwave energy. This paper aims to present the concept of the device and assess the basic functions including the hemostasis, cutting, and sealing abilities. Methods: Seven beagle dogs were used in our experiments. In six dogs, we measured the coagulation time (CT), lateral thermal injury (LTI), bursting pressure (BP). The dogs were then subjected to re-laparotomy 1 week later to allow us to investigate the results. In one dog, the same factors and the quantities of smoke and mist emitted were compared to those observed when using a Harmonic Focus (HF) device. Results: At 60 W, the MWCX could cut and seal small (5 s, diameter 1-2 mm) and medium-sized (10 s, 3-4 mm) vessels with complete hemostasis. The liver (length 2 cm) was cut for 30 s. Harvested vessels were sealed for 10 s (artery, 17 times; vein, six times). The mean BP was 887. 8 ± 41.5 mmHg in the medium arteries and 457.2 ± 118.0 mmHg in veins, with a mean diameter of 4.5 ± 1.3 mm. In a comparative study, the MWCX showed similar results to the HF with regard to the CT, BP and LTI, and emitted less smoke and mist. Conclusion: The MWCX showed similar levels of functionality and safety to HF, as well as the advantages offered by the use of microwave energy. Microwave devices might be used in the majority of applications for which traditional energy devices are used.

ABSTRACT
Purposes Laparoscopic gastrectomy using ultrasonic devices occasionally causes postoperative pancreatic fistula. Robotic gastrectomy using monopolar scissors may reduce intraoperative injury to the pancreas. We evaluated the safety and feasibility of robotic gastrectomy. Methods A multicenter prospective study was conducted to evaluate the surgical outcomes of robotic gastrectomy. The primary endpoints were the incidence of intraoperative and postoperative complications and operative mortality. Results A total of 115 patients were enrolled. The clinical T stages were T1 in 68 patients and T2 or higher in 47 patients. The types of surgery included distal gastrectomy (n = 72), total gastrectomy (n = 39), and proximal gastrectomy (n = 4). Two patients developed intraoperative complications (1,7%), but no cases required conversion to open surgery. The amylase concentration in drainage fluid was higher in cases with pancreatic compression, especially in those with compression for longer than 20 min. Postoperative complications of Clavien-Dindo grade ≥ II occurred in 11 patients (9,6%). There was no mortality. A multivariate analysis indicated that a high body mass index and pancreatic compression by an assistant for longer than 20 min were independent risk factors for postoperative complications (P = 0,029 and P = 0,010). Conclusions Robotic gastrectomy using monopolar scissors is safe and feasible. Robotic dissection without compression of the pancreas may reduce postoperative complications.

The first laparoscopy-assisted gastrectomy for gastric cancer was performed in Japan in 1991. In the ensuing 20 years, at first through a process of trial and error, then through the sharing of master surgeons’ accumulated experience, the procedure has been honed and refined to its current high level. From the beginning, it soon became evident that this much less invasive form of gastrectomy, in comparison with traditional open surgery, led to improved quality of life for postsurgical patients, and use of the procedure spread rapidly among gastric surgeons. Early on, however, there were calls for the establishment of standard techniques and procedures to be followed, with a recognized need to improve the level of safety and the quality of lymph node dissection for local control in cancer treatment. Toward that end, the Laparoscopy-Assisted Gastrectomy Club was formed in 1999. In the following year, because both Japan and Korea experience a high rate of gastric cancer, specialists from those two nations came together to form the Japan–Korea Laparoscopic gastrectomy joint seminar, to facilitate and encourage the exchange of vital information. The result has been to achieve an evolving consensus among specialists in the field of endoscopic surgery in Japan and Korea with expertise that can be shared worldwide. A compilation of the current state-of-the-art is now presented in this volume, with accompanying DVD, which will be of great value to all endoscopic surgeons who perform laparoscopic gastrectomy.

The field of minimally invasive surgery (MIS) has now taken centre stage in modern clinical practice. With ever changing technologies in the field of MIS, such as robotics, there is now the need to train the surgeon to the next degree. Training by simulation, whether virtual, hybrid, or real, allows the surgeon to rehearse, learn, improve or maintain their skills in a safe and stress free environment. Simulation training in laparoscopy and robotic surgery gives a true insight into the latest educational and learning techniques for new technologies in surgery. Written by an international team of experts, this illustrated text provides advice on specialised team training, non technical skills and simulation.

PURPOSE: The aim of this study was to determine the risk factors for anastomotic leakage after laparoscopic rectal surgery.

METHODS: We conducted a prospective trial involving 395 patients with stage 0/I rectal carcinoma who underwent laparoscopic low anterior resection using a double stapling technique. Data concerning variables related to patient background, tumors and surgical factors were evaluated. The outcomes with respect to anastomotic leakage were recorded, and univariate and multivariate analyses were performed to identify relevant risk factors.

RESULTS: The overall anastomotic leakage rate was 8.4%. A univariate analysis showed male gender (P = 0.006) and preoperative blood sugar level (P = 0.0034) to be significantly associated with anastomotic leakage. The variables of gender, preoperative blood sugar level, American Society of Anesthesiologists (ASA) classification (P = 0.15), transanal decompression tube (P = 0.06) and number of stapler cartridges used for rectal transection (P = 0.18) were selected for the multivariate analysis because of their P values being <0.2. The multivariate analysis identified male gender (odds ratio 4.12, P = 0.006) and the absence of a transanal decompression tube (odds ratio 3.11, P = 0.0484) as independent risk factors predicting anastomotic leakage.

CONCLUSIONS: Male gender and the absence of a transanal decompression tube appeared to be independent risk factors for anastomotic leakage. Insertion of a transanal decompression tube may help prevent anastomotic leakage after low anterior resection, particularly in male patients.
