Christoph Holmer, Martin E Kreis
BACKGROUND: Potential advantages of robotic surgery, such as 3-dimensional high-definition vision, wrist-like movements of instruments, stable camera holding, motion filter for tremor-free surgery, and improved ergonomics, may provide better clinical, oncological, and functional outcomes in rectal cancer surgery, as suggested in many comparative studies. However, there has not been a systematic review specific to LAR/TME for rectal cancer that includes both robotic versus laparoscopic and robotic versus open comparative studies...

BACKGROUND: Laparoscopic resection of retroperitoneal mass is challenging because of its location close to major vessels and a limited range of laparoscopic instruments [1-3]. We report a case of a huge retroperitoneal paraganglioma that was successfully excised laparoscopically using maneuver of hanging IVC METHOD: A 67-year-old female had abdominal mass detected during routine check-up. She had no symptoms associated mass. Hematologic, biochemical investigations, and hormone tests reveal normal results...

BACKGROUND: We performed 163 laparoscopic cholecystectomies at our institution during the third quarter of 2016. Direct supply cost per case varied from $524 to $1,022 among 14 surgeons. The purpose of this study was to determine the reasons for cost variation between high- and low-cost surgeons and identify opportunities for cost reduction. METHODS: Average cost of supplies per case was examined for laparoscopic cholecystectomy during a 6-month period. Two groups were created, with the 4 highest-cost surgeons comprising group A and the 2 lowest-cost surgeons comprising group B...

Michael A Belfort, William E Whitehead, Andrey Bednov, Alireza A Shamshirsaz
BACKGROUND: Fetoscopic meningomyelocele repair in a gas-filled uterus is a new technique performed in very few centers. There are few opportunities as well as ethical prohibitions on the initial development and subsequent refinement of innovative fetal surgery techniques in humans, and using an animal model is both very expensive and logistically difficult. METHOD: We developed a low-fidelity endoscopic fetal surgery simulation using a plastic doll and pieces of chicken breast to simulate a fetal meningomyelocele, and a polyurethane ball to simulate a gas-filled uterus, along with a standard endoscopy system and instruments...

REVIEW
Chinock Cheong, Nam Kyu Kim
Although laparoscopic resection for colon cancer has been proven safe and feasible when compared with open resection, currently no clear evidence is available regarding minimally invasive surgery for rectal cancer. This type of surgery may benefit patients by allowing fast recovery of normal dietary intake and bowel function, reduced postoperative pain, and shorter hospitalization. Therefore, minimally invasive surgeries such as laparoscopic or robot surgery have become the predominant treatment option for colon cancer...

BACKGROUND: For left-sided pancreatic ductal adenocarcinoma (PDAC), radical antegrade modular pancreatosplenectomy (RAMPS) is a reasonable surgical approach for tumor-free margin resection and systemic lymph node clearance. In pancreaticoduodenectomy for PDAC, the superior mesenteric artery (SMA)-first approach (or the "artery-first approach") has become the standard procedure. With improvements in laparoscopic instruments and techniques, some surgeons attempted to apply laparoscopic RAMPS (L-RAMPS) for carefully selected patients with left-sided PDAC...

BACKGROUND: Recently, the Expanded Prostate Cancer Index Composite 26-item version (EPIC-26) was recommended for the assessment of adverse effects after the treatment of prostate cancer without clear reasons. This decision encouraged us to review the questionnaire development from the UCLA Prostate Cancer Index (UCLA-PCI) to the EPIC-16 CP with a focus on psychometric properties. We also reviewed PubMed for papers concerning such properties of the EPIC-26 since 2012 (latest review in 2011)...

A retained intra-abdominal foreign body is a common occurrence that is frequently underreported due to its medicolegal implications. Sponges, gauzes, surgical instruments, abdominal drains, etc. have been reported in the literature. The most common presentation for a retained intra-abdominal foreign body is postoperative abdominal infections or bleeding, frequently seen in the immediate postoperative period. Most of these foreign bodies are removed by exploratory laparotomy owing to recent abdominal surgeries or presentation as complicated abdominal masses...

AIM: To evaluate the results of Rehbein procedure with extraperitoneal colorectal anastomosis combined with complex conservative treatment in children with secondary megacolon due to chronic constipation. MATERIAL AND METHODS: We carried out surgical interventions in 78 children aged 7-12 years with chronic colostasis resistant to conservative treatment. All patients underwent clinical, laboratory and instrumental examination. All patients were divided into 3 groups depending on type of surgery: group I - colon resection followed by intraperitoneal colorectal anastomosis (28 patients), group II - open Rehbein procedure (29 patients), group III - laparoscopic Rehbein procedure (21 patients)...

In laparoscopic surgery, the surgeon must operate with a limited field of view and reduced depth perception. This makes spatial understanding of critical structures difficult, such as an endophytic tumour in a partial nephrectomy. Such tumours yield a high complication rate of 47%, and excising them increases the risk of cutting into the kidney's collecting system. To overcome these challenges, an augmented reality guidance system is proposed. Using intra-operative ultrasound, a single navigation aid, and surgical instrument tracking, four augmentations of guidance information are provided during tumour excision...

Bariatric surgery has proven benefits for morbid obesity and its associated comorbidities. Laparoscopic approach is well established for bariatric surgery. Single-incision laparoscopic surgery (SILS) offers even more minimally invasive approach for the same with the added advantage of better cosmesis. We have developed and standardised the SILS approach at our institute. We share our experience and technical "tips" and modifications which we have learnt over the years. Technical details of performing sleeve gastrectomy and Roux-en-Y gastric bypass with special attention to liver retraction, techniques of dissection in difficult areas, creation of anastomoses and suturing have all been described...

There has been an overall increase in pelvic organ prolapse due to demographic changes (increased life expectancy). Increasing sociocultural demands of women require treatments that are more effective with methods that are more successful. In the treatment of pelvic floor insufficiency and uterovaginal prolapse, pelvic floor reconstructions with mesh implants have proven to be superior to conventional methods such as the classic colporrhaphy, reconstructions with biomaterial, and native tissue repair in appropriately selected patients and when applying exact operation techniques, especially because of good long-term results and low recurrence rates...

INTRODUCTION: Trans-umbilical laparoscopic-assisted appendectomy (TULAA) combines advantages of open surgery with benefits of laparoscopy and can be performed either by single-incision or with two trocars; the present study aims to compare outcomes and cost of these techniques in a pediatric serie. MATERIAL AND METHODS: Patients undergoing TULAA between July 2013 and June 2014 were retrospectively reviewed. There were two groups: A (single-incision) - one umbilical trocar for a telescope with inbuilt working channel; and B (2-trocar) - one umbilical trocar for a 'standard' telescope plus a supra-pubic trocar for instruments...

In many developing countries like Cameroon, unsafe abortion is a major public health problem. It can be responsible for severe complications including damage to the digestive and/or urinary tract, sepsis, and uterine perforation. Uterine perforation could be caused by most of the instruments that are used to evacuate the uterus. We report a case of apparent uterine perforation and subsequent migration of the plastic or rubber catheter into the peritoneal cavity during an abortion procedure performed in a setting that may have been unsafe...
