Ahead of Print article withdrawn by publisher. An 80-year-old woman presented necrotizing fasciitis on the right flank, requiring debridement. Tomography reported ascending colon neoplasm fistulized to the skin.

Application of 3D-reconstruction and artificial intelligence for complete mesocolic excision and D3 lymphadenectomy in colon cancer.

Mathematical algorithms 3D-reconstruction techniques and artificial intelligence are a current line of innovation in colorectal surgical oncology. The objective of this study is to show the initial experience of a 3D image processing and reconstruction system to perform complete mesocolic excision and D3-lymphadenectomy in colon cancer. It is applied to a splenic flexure neoplasm and in a right colon cancer with suspected retroperitoneal infiltration.

Analysis of potential risk factors in the survival of patients with primary retroperitoneal liposarcoma.

Introduction: The present work is an observational study of a series of variables regarding overall survival and disease-free survival in patients diagnosed with primary liposarcoma.

Methods: The study is prospective with retrolective data collection that includes all patients with primary liposarcoma referred to Hospital Son Espases University Hospital, Palma de Mallorca, Spain from January 1990 to December 2019.

Results: The study includes 50 patients and the compartment surgery was performed in 18 patients (36%) of cases.

Near-infrared fluorescence cholangiography at a very low dose of indocyanine green: quantification of fluorescence intensity using a colour analysis software based on the RGB color model.

Background: Indocyanine green (ICG) near-infrared fluorescence cholangiography (NIRF-C) is widely used to visualize the biliary tract during laparoscopic cholecystectomy (LC). However, the ICG dose and its dosing time vary in the literature so there is not a standard ICG protocol. The objectives of this descriptive prospective study were to demonstrate that NIRF-C at a very low dose of ICG provides good visualization of the extrahepatic biliary tree while avoiding hepatic hyperluminescence and to assess the surgeon-perceived benefit.

Anal intraepithelial neoplasia screening in patients with human immunodeficiency virus infection.

Introduction: the incidence of anal cancer has increased in recent years, making screening and early detection of anal intraepithelial neoplasia (AIN) a necessity in patients at risk.

Methods: a descriptive observational study of homosexual patients (MSM) or women with cervical intraepithelial neoplasia (CIN) III, with human immunodeficiency virus (HIV) infection, included in an AIN detection screening program was carried out between March 2016 and September 2019.

Results: we have performed 695 anal smears, 156 with results of LSIL (low-grade lesion) or HSIL (high-grade lesion) (22.

Cephalic pancreaticoduodenectomy for ductal adenocarcinoma in the elderly. Can we do it safely?

Introduction: Surgery and chemotherapy have increased the survival of pancreatic cancer. The decrease in postoperative morbidity and mortality and increase in life expectancy, has expanded the indications por cephalic pancreaticoduodenectomy (PDC), although it remains controversial in the geriatric population.

Methods: Retrospective study on a prospective database of patients with ductal adenocarcinoma of pancreas who underwent PDC between 2007-2018.

Abdominal metastatic melanoma invading the transverse colon and stomach.

Gastrointestinal melanoma metastases are not uncommon, with the jejunum and ileum being the most common locations (58 %), followed by the stomach (26 %), colon (22 %), duodenum (12 %), and rectum (5 %).

Long-term comparative study on open versus laparoscopic biliopancreatic diversion.

Background: To date, bariatric surgery has been proposed as the most effective treatment to resolve morbid obesity, a multifactorial chronic disease with an epidemic and increasing tendency. The purpose of this study was to determinate the impact of the laparoscopy on weight loss parameters in morbid obese patients who underwent surgery according to Scopinaro's biliopancreatic diversion (BPD) and evaluate early and late complications related to the open and laparoscopic approach of this technique.

Materials And Methods: This is a longitudinal retrospective study in consecutive patients undergoing BPD due to morbid obesity between 1999 and 2015.

Biliopancreatic Diversion in the Surgical Treatment of Morbid Obesity: Long-Term Results and Metabolic Consequences.

Purpose: In the multidisciplinary therapeutic approach to obesity, bariatric surgery is considered the most effective treatment in weight reduction and the decrease in associated comorbidities. The objective of this work is to describe the long-term clinical and metabolic results in obese patients undergoing biliopancreatic diversion (BPD) according to Scopinaro's technique.

Materials And Methods: Patients undergoing surgery were followed by the same multidisciplinary team in a study period of 15 years (1999-2015).

New hemostatic device for grade IV-V liver injury in porcine model: a proof of concept.

Background: The liver is the most injured organ following abdominal trauma. Uncontrolled bleeding remains the main cause of early liver injury-related death, with a mortality rate of 50-54% in the first 24 h after admission and with 80% of operative deaths. Packing and reoperation account for the increased survival in severe liver trauma, and they are recommended for severe liver injuries (grades IV-V).

Contributions of fluorescence to endocrine surgery.

The use of fluorescence in surgery has expanded and become widespread in recent years, which has led to a real technological phenomenon with the emergence of devices adapted for use in laparoscopic and robotic approaches. Fluorescence-guided surgery in the field of endocrine surgery is also on the rise. More and more articles describe its use in surgery of the thyroid, parathyroid and adrenal glands, although the series are still modest in size and protocols have not been standardized.

Dorsal inflammatory mass secondary to lost stones after laparoscopic cholecystectomy.

The most frequent intraabdominal complication after lost stones are abscesses, which account for 65% of complications. The main risk factors are: old age, male gender, surgical difficulty, leakage of lithiasis of more than 1.5 cm or more than 15 stones, perihepatic location and pigmented gallstones.

Laparoscopic transgastric endoscopic retrograde cholangiopancreatography after biliopancreatic diversion.

Endoscopic retrograde cholangiopancreatography may be difficult in patients that have undergone Roux-en-Y gastric bypass. Due to the fact that prevalence of morbid obesity is increasing, and laparoscopic procedures for its treatment have increased, the incidence of biliary tract problems in patients of altered anatomy is also growing. We describe a laparoscopic technique to access the biliary tree by endoscope, through the excluded stomach.
