AIMS: The role of laparoscopy in rectal cancer has been questioned. 3D laparoscopic systems are suggested to aid optimal surgical performance but have not been evaluated in advanced procedures. We hypothesised that stereoscopic imaging could improve the performance of laparoscopic total mesorectal excision (TME). METHODS: A multicentre developmental randomised controlled trial comparing 2D and 3D laparoscopic TME was performed (ISRCTN59485808). Trial surgeons were colorectal consultants that had completed their TME proficiency curve and underwent stereoscopic visual testing...

BACKGROUND: Laparoscopic right hemicolectomy has become an acceptable treatment for right-sided colon cancer. Most centers use multiport laparoscopic right hemicolectomy extracorporeally (MRHE), whereas single-incision laparoscopic right hemicolectomy intracorporeally (SRHI) remains controversial. The aim of this study was to compare these two techniques using propensity score matching analysis. METHODS: We analyzed the data from 111 patients who underwent laparoscopic right hemicolectomy between December 2015 and December 2016...

BACKGROUND: It remains unclear whether use of self-fixating mesh during laparoscopic inguinal hernia repair (LIHR) impacts postoperative quality of life (QoL). We hypothesize patients receiving self-fixating mesh during totally extraperitoneal (TEP) LIHR will report less pain and improved QoL compared to those receiving non-fixating mesh. METHODS: An IRB-approved, single-blinded randomized controlled trial was conducted. Patients with primary, unilateral inguinal hernias were randomized to receive either non-fixating (control) or self-fixating mesh...

BACKGROUND AND OBJECTIVES: Two-dimensional (2D) images lack depth information and thus provide probabilistic recognition that do not completely match the actual three-dimensional (3D) information. Here, we investigated the operability of 3D endoscopes. METHODS: A 3D operation model was developed by passing 20 silk threads through upper and lower plates at 2-mm intervals in front and back rows separated by 1 mm. We evaluated accuracy and time of operating an electrosurgical knife...

BACKGROUND: Complete cyst excision with Roux-en-Y hepaticojejunostomy is the standard procedure for choledochal cysts (CCs). In recent years, neonates have been increasingly diagnosed with CCs prenatally. Earlier treatment has been recommended to avoid complications. For type IVa malformation without extensive intrahepatic bile duct dilatation, laparoscopic hepaticojejunostomy is technically challenging, and anastomotic stricture is a concern. Therefore, we propose laparoscopic synthetical techniques-laparoscopic excision of cyst and ductoplasty plus widened portoenterostomy to avoid stricture in CCs with a narrow hilar duct...

BACKGROUND: Duodenal neuroendocrine tumors (NETs) measuring ≤ 10 mm in diameter that are confined to the submucosal layer without metastasis are suitable for endoscopic treatment. We previously reported the efficacy and safety of endoscopic submucosal resection with a ligation device (ESMR-L) for duodenal NETs. In order to make the procedure simpler, we attempted ESMR-L without submucosal injection. The aim of this study was to evaluate the efficacy of ESMR-L without injection for duodenal NETs...

BACKGROUND: Colon perforation is the most serious complication associated with colonoscopic procedures. We performed a novel purse-string suture technique to close the iatrogenic colonic perforation using dual-channel endoscope with an endoloop and clips. METHODS: Iatrogenic colon perforations developed during diagnostic colonoscopy referred to a tertiary hospital over 10 years were considered for this endoscopic closure. An endoloop was inserted through the left channel of the endoscope and placed around the defect...

BACKGROUND: For therapeutic endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (ES) is necessary but it can lead to complications such as bleeding. Thus, we investigated the risk factors of post-ES bleeding in average risk patients. METHODS: We retrospectively reviewed the medical records of patients who had been treated for ERCP between April 2006 and March 2013. The length of the ES incision was defined as minimal (up to proximal hooding fold), medium (between minimal and full length), and full (up to superior margin of sphincter opening)...

BACKGROUND: For comparison of laparoscopic IPOM versus sublay technique for elective incisional hernia repair, the number of cases included in randomized controlled trials and meta-analyses is limited. Therefore, an urgent need for more comparative data persists. METHODS: In total, 9907 patients with an elective incisional hernia repair and 1-year follow-up were selected from the Herniamed Hernia Registry between September 1, 2009 and June 1, 2016. Using propensity score matching, 3965 (96...
