BACKGROUND: Minimally invasive surgery has been validated to be a new standard in living donor hepatectomy for adult-to-pediatric transplantation with less morbidity [1]. Laparoscopic donor hepatectomy can reduce the major concerns about pain and morbidity associated with open surgery and a slow return to daily activities of donors [2]. Herein, we present one case of totally laparoscopic living donor left hepatectomy including the middle hepatic vein (MHV). DONOR AND METHOD: A 37-year-old mother volunteered to donate to her 3-year-old son with biliary atresia (PELD score 7)...

Remote-access approaches to the thyroid gland have seen a rapid evolution recently with the development of various techniques to minimize the cosmetic and quality-of-life impact of a visible scar. Most approaches have required significantly more tissue dissection and have been limited in their extent to treat contralateral disease. The transoral approach is the most recent iteration of "scarless" thyroidectomy and offers various advantages over other techniques including less tissue dissection, equal access to both sides of the neck, and a superb midline view of the anatomy...

Knowledge of ureteric anatomy is essential for ureteric injury prevention in laparoscopic gynecologic surgery. Rates of injury increase with limited surgical experience and reduced surgical volume. Currently there are no low-fidelity or high-fidelity simulation models for teaching and practicing ureteric dissection. Our goal was to design a laparoscopic simulation model for retroperitoneal anatomy with high face validity that is low-cost and easily reproducible.

Leaks arising at the level of gastro-esophageal junction remain a major complication in patients who undergo a laparoscopic sleeve gastrectomy. Besides technical pitfalls, these fistulas are mainly attributable to tissue ischemia following the preparation of the gastric sleeve, explained by the irregular vascularization often present in the area of the gastro-esophageal junction. This video presentation shows how, the utilization of a new model of bougie can be of help in preventing a leak, allowing a better visualization of the particular vascular anatomy present at the level of the gastro-esophageal junction area...

PURPOSE: Identification of the infrapyloric artery (IPA) type is a key component of pylorus-preserving gastrectomy. As the indocyanine green (ICG) fluorescence technique is known to help visualize blood vessels and flow during reconstruction, we speculated that this emerging technique would be helpful in identifying the IPA type. MATERIALS AND METHODS: From August 2015 to February 2016, 20 patients who underwent robotic or laparoscopic gastrectomy were prospectively enrolled...

The anatomy of the human being has not changed. However, technical developments in operating materials and methods call for improvements in surgical procedures as well as the management of complications. A fundamental distinction between any operating method and laparoscopy is that, in the latter, the initial entry is usually performed in blind fashion. Blind entry may result in vessel or organ damage, especially in patients who have undergone previous surgery. One of the difficulties associated with the entry is that the damage may not be identified immediately and then necessitate major abdominal repair...

Rectal cancer with simultaneous liver metastasis is very common clinically. R0 surgical resection both for the original and metastatic tumor can achieve much better long-term oncological results. The operation types include traditional open procedures for both rectal cancer and liver metastatic resection; combination of laparoscopic resection of the rectal cancer and open procedure resection of the liver metastatic lesion; traditional laparoscopic-assisted rectal and liver metastatic tumor resection with small abdominal incision and total laparoscopic natural orifice specimen extraction surgery(NOSES) without abdominal incision...

INTRODUCTION: Various reconstructions of the gastro-intestinal tract have been described in the past after distal gastrectomy. Among these, a Billroth II (BII) anastomosis can be performed with the addition of the Omega entero-enterostomy that may theoretically reduce the alkaline reflux. Given the significant complications associated with this procedure such as biliary reflux, marginal ulceration, and afferent loop syndrome, a revision into a Roux-en-Y anatomy is generally recommended...

BACKGROUND: Laparoscopic gastric devascularization(Lap GDS) and splenectomy (SPL) for gastric varices is technically challenging because of highly developed collateral vessels and bleeding tendency. We investigated the feasibility of customization of Lap GDS and SPL based on CT vascular anatomy. METHODS: We analyzed 61 cirrhotic patients with gastric varices who underwent Lap GDS and SPL between 2006 and 2014. Lap GDS was customized according to the afferent feeding veins (left gastric vein (LGV) and/or posterior gastric vein (PGV)/short gastric vein (SGV)) and efferent drainage veins (gastrorenal shunt and/or gastrophrenic shunt, or numerous retroperitoneal veins) based on CT imaging...

Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

Surgical resection represents the mainstay treatment and only potentially curative option for gastric carcinoma, and is increasingly performed laparoscopically. Furthermore, other tumours and selected cases of non-malignant disorders of the stomach may require partial or total gastrectomy. Often performed in elderly patients, gastric resection remains a challenging procedure, with significant morbidity (14-43% complication rate) and non-negligible postoperative mortality (approximately 3%). This paper provides an overview of contemporary surgical techniques for non-bariatric gastric resection, reviews and illustrates the expected postoperative imaging appearances, common and unusual complications after partial and total gastrectomy...

BACKGROUND: Gallbladders (GBs) with severe inflammation have longer operative times and an increased risk for complications. We propose a grading system using intraoperative images to better stratify GB inflammation. METHODS: After reviewing the intraoperative images of GBs obtained during several hundred laparoscopic cholecystectomies, we developed a five-tiered grading system based on anatomy and inflammatory changes. Fifty intraoperative photographs were taken prior to dissection and then distributed to 11 surgeons who rated each GB's severity per the grading system...

Improved surgical techniques and immunosuppressant medications for organ transplantation have resulted in a significant increase in the number of women undergoing renal transplantation. Peritoneal dialysis (PD), a common supportive therapy for chronic renal failure, is also used in cases of renal transplantation failure. Herein, we report the first case of a rare total conventional laparoscopic gynecologic hysterectomy performed for endometrial cancer in a patient undergoing life-supportive PD as a result of renal transplantation failure...

Colorectal carcinoma is common worldwide and its metastasis represents the main cause of mortality related to the disease. Inguinal metastization of this tumor has been considered almost impossible, owing to colon anatomy and its cranial lymphatic drainage. We report the case of a 63-year-old man submitted to laparoscopical sigmoid colectomy, due a sigmoid adenocarcinoma. During follow-up, a right inguinal lymphadenopathy with 25 mm was detected. Fine needle aspiration biopsy revealed that it was a colon adenocarcinoma metastasis, and thus the patient underwent an inguinal lymphadenectomy...

BACKGROUND: Laparoscopic cholecystectomy is considered to be gold standard treatment for symptomatic gall stones. Despite several benefits there are still disadvantages of laparoscopic cholecystectomy in difficult cases where anatomy is disturbed even in experienced hand. Aim of this study is to identify advantages of early conversion to open cholecystectomy in difficult cases and how it should not be associated with surgeon's failure. METHODS: Observational study was conducted at tertiary care hospital of Karachi, Pakistan from January 2012 till June 2015...

BACKGROUND: Intravenous injection of indocyanine green (ICG) is used to illuminate extrahepatic biliary anatomy. Fluorescence of biliary structures may lower surgical complications that can arise due to inadvertent injury to the common bile duct. We describe a method of injecting ICG directly into the gallbladder to define the cystic duct and common bile duct anatomy. MATERIALS AND METHODS: A standard laparoscopic cholecystectomy was performed using a laparoscope with near-infrared imaging capability...

OBJECTIVE: Weight-loss surgery results in significant changes in the anatomy, function and intraluminal environment of the gastrointestinal tract affecting the gut microbiome. While bariatric surgery results in sustained weight loss, decreased appetite and hedonic eating; it is unknown if the surgery-induced alterations in gut microbiota play a role in the observed changes in hedonic eating. We explored the following hypotheses 1) Laparoscopic sleeve gastrectomy results in changes in gut microbial composition ; 2) Alterations in gut microbiota are related to weight loss; 3) Alterations in gut microbiome are associated with changes in appetite and hedonic eating...

Situs inversus totalis is a rare congenital condition, characterized by the transposition of the thoracic and abdominal viscera, resulting in a mirror image of normal anatomy. Even though situs inversus does not predispose to gall stones, a laparoscopic cholecystectomy, in a case of situs inversus, can prove to be a technically challenging procedure, especially for the right-handed surgeon. In this case report, we present an unusual case of cholelithiasis in a patient with situs inversus totalis. A laparoscopic cholecystectomy, which is considered the gold standard procedure for symptomatic gallstones, was performed...
