Chuangang Fu, Junyi Han
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...

OBJECTIVE: 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...

Interstitial pregnancies account for 2-4 % of all ectopic pregnancies. Despite its rarity, various treatment options exist. However, no gold standard has yet been defined and data regarding recurrence of interstitial pregnancies in subsequent pregnancies after different treatments are sparse. This makes it very difficult to provide adequate patient counselling for treatment options with regards to the treatment-related risk of recurrence. The present literature review demonstrates that recurrent interstitial pregnancy is a rare condition and more likely when additional anatomy-related risk factors for ectopic pregnancies are present, such as hydrosalpinges, blocked tubes, endometriosis, fibroids or prior tubal ectopic pregnancies...

Hernia repair techniques vary greatly depending upon the setting, surgeons, insurance reimbursement systems, resources, and logistical capabilities. Open mesh repair is the most frequently used technique. Choosing the best technique for inguinal hernia repair is a challenge. There is no single technique to manage every type of hernia. Today, laparoscopy and robotics are at the forefront of advanced surgical tools and offer a range of options for general surgeons who are critically evaluating new procedures...

Biliary duct anomalies are commonly encountered during laparoscopic cholecystectomy. Advancements in the field of surgery allow for enhanced intraoperative detection of these abnormalities. Fluorophore injection and near-infrared (NIR) imaging can provide real-time intraoperative anatomic feedback without intraoperative delays and ionizing radiation. This report details two cases where the PINPOINT Endoscopic Fluorescence Imaging System (NOVADAQ, Ontario, Canada) was used to identify anomalies of the biliary tree and guide operative decision-making...

Gastric volvulus (GV) is characterized by the abnormal rotation of a portion of the stomach around a horizontal or vertical axis that can cause obstruction, vascular disorder and even strangulation, and may evolve into necrosis or even perforation. It can be classified according to its aetiology into primary or secondary GV, according to its anatomy into axial organ or into axial mesenteric GV, and according to its presentation into chronic or acute GV. Both types of volvulus require treatment; however, in spite of the classic treatment being open surgery, there is no standard treatment, nor is there consensus on the alternative of choice at present...

The most frequent ureteral lesions are iatrogenic, mainly due to gynecologic and urologic procedures. The resolution and repair of these lesions, when they require surgery, is often the performance of ureteroneocystostomy. We describe the technique for the repair of distal ureter lesions that preserves both anatomy and function of the urinary tract (1). The operation consists in dissection and extraction of the distal ureteral stump from its intramural tract to get at least 1 cm of free ureter, percutaneous insertion of a ureteral stent, checking the absence of tension between proximal ureter and distal dissected stump, end to end anastomosis and reinsertion of the distal ureter in the previously dissected bladder muscle layer...

OBJECTIVES: Surgical restoration of pelvic floor anatomy in pelvic organ prolapse (POP) should avoid extensive areas that may injure healthy tissues and lead to scar fibrosis producing dysfunctional rigidity. Laparoscopic sacrocolpopexy corrects POP by lifting pelvic elements with a minimally invasive procedure.Various current strategies and approaches make it a diverse procedure. METHODS: We performed a bibliographic review on the published experience about abdominal sacrocolpopexy over the last 20 years...

To help understand the three-dimensional (3D) spatial relationships among the highly complex structures of the pelvis, we made a novel 3D pelvic model with a 3D printing system. We created two pelvic models including the muscles, vessels, nerves, and urogenital organs; the first based on the pelvic anatomy of a healthy male volunteer and the second on the pelvic anatomy of a female volunteer with rectal cancer. The models clearly demonstrated the complicated spatial relationships between anatomical structures in the pelvis...
