Upper urinary tract calculi with infection is a quite difficult acute urologic emergency. And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation. Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk. But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying...

Inguinal hernia repair is one of the most commonly performed operations in the pediatric population. While the majority of pediatric surgeons routinely use laparoscopy in their practices, a relatively small number prefer a laparoscopic inguinal hernia repair over the traditional open repair. This article provides an overview of the three port laparoscopic technique for inguinal hernia repair, as well as a review of the current evidence with respect to visualization and identification of hernias, recurrence rates, operative times, complication rates, postoperative pain, and cosmesis...

BACKGROUND: Laparoscopic complete mesocoloic excision (CME) with central vascular ligation for splenic flexure cancer is technically challenging because of its anatomical complexity. Although embryological and anatomical consideration should be helpful to perform CME in colorectal cancer surgery, such studies on the splenic flexure are lacking. METHODS: The splenic flexure is located embryologically between the terminal portion of the midgut and the beginning of the hindgut, and is supplied by the superior mesenteric and inferior mesenteric arteries...

Open anterior repair for inguinal hernia offers several distinct advantages over endoscopic repair, especially when real-world effectiveness is taken into account. The learning curve for endoscopic techniques is long, whereas the Lichtenstein and other open tension-free techniques are easier to teach and replicate at all levels. The outcomes of Lichtenstein repairs for primary inguinal hernia as performed by non-experts and supervised residents are comparable to those of experts. Moreover, open tension-free repair does not require expensive instruments or dedicated equipment, other than the prosthetic mesh...

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. A low-fidelity 3-dimensional simulation model was developed that represents key anatomic structures encountered during retroperitoneal dissection and ureteric identification...

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...

Ibrahim Alkatout
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...
