OBJECTIVES: Previous studies, comparing women with deep infiltrating endometriosis (DIE) and healthy controls, underlined an association between pelvic floor muscle (PFM) hypertonic dysfunction and deep lesions. The aim of the study is to compare the morphometry of pelvic floor muscle (PFM) in women affected by ovarian endometriosis with or without DIE, to assess the impact of retroperitoneal infiltration by the disease on PFM function. METHODS: A prospective study was conducted between March 2015 to December 2016 on symptomatic women with clinical and sonographic diagnosis of ovarian endometriosis with or without DIE, submitted to laparoscopic surgery...

Lymph node dissection is a critical part of surgery for colorectal cancer. Japanese D3 and complete mesocolic excision are two unique principles for lymph node dissection in colorectal cancer. Laparoscopic surgery magnifies the targets and provides insight about the micro-anatomy through high-quality, high-definition imaging, which benefits the surgeon. Although laparoscopic colorectal resection is feasible, there is no universal procedure. We describe in detail the anatomy viewed during lymph node dissection around the inferior mesenteric artery...

BACKGROUND: Laparoscopic subtotal cholecystectomy (LSC) is considered a safe alternative to laparoscopic cholecystectomy (LC) if biliary anatomy is obscured by inflammation. While case series studies have observed low morbidity rates with LSC, the impact of operative conversion on patient outcomes is poorly understood. METHODS: A national analysis of all patients who underwent LC or LSC from 2009 to 2013 was performed using the University HealthSystem Consortium database...

Objective: It is considered that laparoscopic single-site surgery should be performed by specially trained surgeons because of the technical difficulty in using special instruments through limited access. We investigated suitable patients for single-port laparoscopic radical nephrectomy, focusing on the anatomy and distribution of the renal artery and vein. Methods: This retrospective study was conducted in 52 consecutive patients who underwent single-port radical nephrectomy by the transperitoneal approach...

REVIEW
Hiroaki Nozawa, Toshiaki Watanabe
Laparoscopic surgery has gained acceptance as a less invasive approach in the treatment of colon cancer. However, laparoscopic surgery for rectal cancer, particularly cancer of the lower rectum, is still challenging because of limited accessibility. Robotic surgery overcomes the limitations of laparoscopy associated with anatomy and offers certain advantages, including 3-D imaging, dexterity and ambidextrous capability, lack of tremors, motion scaling, and a short learning curve. Robotic rectal surgery has been reported to reduce conversion rates, particularly in low anterior resection, but it is associated with longer operative times than the conventional laparoscopic approach...

Young Seok Han, Heontak Ha, Hyung Jun Kwon, Jae Min Chun
RATIONALE: With refinements in the operative technique, laparoscopic surgery has become the standard practice for liver resection. In the field of living donor liver transplantation, a few centers adopted laparoscopic surgery as an alternative to conventional open donor hepatectomy, and the application of pure laparoscopic donor right hepatectomy has been limited to the donors with simple, favorable biliary anatomy. PATIENT CONCERNS: The candidate donor was a 19-year-old woman with type 3a bile duct variation...

Common bile duct (CBD) injury is the most serious complication of laparoscopic cholecystectomy. Recently, laparoscopic techniques have been used in the management of postoperative bile leak and CBD injury; this literature has not been reviewed. We reviewed the literature on CBD injury, the approach to its diagnosis and management, and reports of laparoscopic management techniques. We combined this review with our experience in laparoscopic methods to highlight diagnostic and therapeutic options. Laparoscopic techniques can be used to prevent, diagnose and treat CBD injuries...

BACKGROUND: Near-infrared (NIR) fluorescence cholangiography by systemic administration of indocyanine green (ICG) enhances the visualization of the biliary tree anatomy. However, the simultaneous enhancement of liver parenchyma can disturb the visualization of critical details. We herein proposed a new technique of NIR cholecystocholangiography by intragallbladder ICG injection to increase the safety during laparoscopic cholecystectomy. METHODS: A total of 46 patients scheduled for laparoscopic cholecystectomy for symptomatic lithiasis (n = 21) or cholecystitis (n = 25) were enrolled...

This article focuses on the anatomy, literature, and our own experiences in an effort to assist in the decision-making process of choosing between an umbilical or vaginal port. Umbilical access is more familiar to general surgeons; it is thicker than the transvaginal entry, and has more nerve endings and sensory innervations. This combination increases tissue damage and pain in the umbilical port site. The vaginal route requires prophylactic antibiotics, a Foley catheter, and a period of postoperative sexual abstinence...

BACKGROUND: Bile duct injury (BDI) during laparoscopic cholecystectomy remains a serious iatrogenic surgical complication. BDI most often occurs as a result of misidentification of the anatomy; however, clinical evidence on its precise mechanism and surgeons' perceptions is scarce. METHODS: Surgeons from Japan, Korea, Taiwan, and the U.S., etc. (n = 614) participated in a questionnaire regarding their BDI experience and near-misses; and perceptions on landmarks, intraoperative findings, and surgical techniques...

BACKGROUND: Laparoscopic cholecystectomy (LC) has many advantages as compared to open cholecystectomy. However, vasculobiliary injuries still continue to be a matter of concern despite advances in laparoscopic techniques. Misidentification and misperception of vasculobiliary structures is considered to be a pivotal factor leading to injuries. Although many studies since time immemorial have stressed on the importance of anatomy, an insight into laparoscopic anatomy is what essentially constitutes the need of the hour...

BACKGROUND: To treat colon cancer via complete mesocolic excision (CME) with central vascular ligation (CVL), dissection along the embryologic fusion planes is required. However, this surgery is difficult, especially for right-sided colon cancer, because the anatomy and embryology of the transverse mesocolon are not familiar to gastrointestinal surgeons. METHODS: In this video article, the anatomic details of the transverse mesocolon based on embryology are illustrated with a focus on the venous anatomy...

Transanal total mesorectum excision (taTME) is a novel approach to treat rectal cancer by colorectal surgeons. How to standardize taTME is important for colorectal surgeons, especially at their initial attempt. They can start this approach cautiously only after they master skilled laparoscopic technique and pelvic anatomy, get the knowledge of taTME clearly, and are approved by healthcare department. The female patients with age <70 years old, distance of 5 to 7 cm from tumor inferior margin to anal verge, tumor size <3 cm, cTNM stage <T3aN0 are suitable for taTME...

Laparoscopic radical gastrectomy for gastric cancer has been widely applied in clinical practice, and its indications have been extended from early gastric cancer to advanced gastric cancer. It is acknowledged that laparoscopic radical gastrectomy is technically challenging because of the complexity of anatomy, rich blood supply, and extensive lymph node dissection. This paper primarily intends to share the experience of laparoscopic radical D2 gastrectomy for distal gastric cancer with details of choosing the location of Trocar, surgical approaches and the sequence of lymph node dissection...
