Impact of sarcopenic obesity on surgical complications and oncologic outcomes of upper gastrointestinal tumors: a systematic review and meta-analysis.

Sarcopenic obesity (SO) is a new entity whose definition encompasses the diagnosis of overweight in malnourished patients. The aim of the review was to assess the impact of body composition in patients with esophago-gastric tumors (EGT) on perioperative and oncological outcomes. This systematic review was conducted under the PRISMA guidelines.

Risk factors associated with radiological and clinical recurrences after laparoscopic repair of large hiatal hernia with TiOMesh™ reinforcement.

Introduction: Laparoscopic repair of large para-esophageal hiatal hernias (LPHH) remains controversial. Several meta-analyses suggest hiatus reinforcement with mesh has better outcomes over cruroplasty in terms of less recurrence. The aim of this study was to evaluate the medium-term results of treating LPHH with a biosynthetic monofilament polypropylene mesh coated with titanium dioxide to enhance biocompatibility (TiOMesh™).

Impact of Neoadjuvant Treatment on Body Composition in Patients with Locally Advanced Gastric Cancer.

Neoadjuvant chemotherapy (NT) followed by radical surgery is the standard treatment for locally advanced gastric cancer (GC). The incidence of sarcopenia in upper gastrointestinal tract malignancies is very high, and it may be increased after NT. This study aimed to evaluate the impact of NT on body composition.

Impact of Sarcopenic Obesity on Long-Term Cancer Outcomes and Postoperative Complications After Gastrectomy for Gastric Cancer.

Background: The prevalence of sarcopenia in gastric cancer (GC), although varying among the reported studies, is around 60%. In the last few years, it has been recognised that sarcopenia can also occur not only in patients with weight loss and low body weight, but also in patients with normal or increased body mass index. Therefore, the term sarcopenic obesity (SO) is a new definition that further expands the implications of altered body composition.

Dose-escalated neoadjuvant chemoradiotherapy for locally advanced oesophageal or oesophagogastric junctional adenocarcinoma.

Background: Neoadjuvant chemoradiotherapy with CROSS-protocol is the standard of care for locally advanced esophageal cancer. The purpose of this study was to demonstrate an improvement in complete pathological response (ypCR) after a dose-escalation neoadjuvant protocol compared to standard treatment. Secondary endpoints were disease-free survival (DFS) and acute gastrointestinal toxicity.

Oncological outcomes of laparoscopic versus open gastrectomy after neoadjuvant chemotherapy for locally advanced gastric cancer: a retrospective multicenter study.

Background: The oncological outcomes of laparoscopic gastrectomy (LG) and open gastrectomy (OG) following neoadjuvant chemotherapy have been investigated in a few studies. Our purpose was to evaluate the oncological outcomes of LG and OG after neoadjuvant chemotherapy in patients with locally advanced gastric cancer (GC) and to determine the advantages, preferences, and ease of use of the two techniques after chemotherapy.

Methods: We conducted a retrospective chart review of all patients who underwent either OG (n = 43) or LG (n = 41).

Influence of positive margins on tumour recurrence and overall survival after gastrectomy for gastric cancer.

Background: Incidence of positive surgical margins after curative gastrectomy ranges from 1% to 20%. It has been suggested that positive surgical margin is an adverse prognosis factor, with a higher local recurrence and worse overall survival (OS). However, the management of these patients remains unclear.

Fertility and Pregnancy Outcomes in Women with Polycystic Ovary Syndrome Following Bariatric Surgery.

Context: Restoration of ovulation is quite common in women with polycystic ovary syndrome (PCOS) after surgically induced weight loss. Whether or not this results in an improvement of PCOS-associated infertility is uncertain.

Objective: To study fertility and gestational outcomes in women with PCOS after bariatric surgery.

Impact of interval timing to surgery on tumor response after neoadjuvant treatment for gastric cancer.

Introduction: neoadjuvant chemotherapy (NACT) followed by radical surgery is the optimal approach for locally advanced gastric cancer (GC). Interval timing to surgery after NACT in GC is controversial. The aim of this study was to evaluate the impact of NACT interval time on tumor response and overall survival.

Assessment of short-term outcome with TiO mesh in laparoscopic repair of large paraesophageal hiatal hernias.

Background: Laparoscopic large para-oesophageal hiatal hernia (LPHH) repair using mesh reinforcement significantly reduces postoperative recurrence rates compared to conventional suture repair, especially within short follow-up times. However, the ideal strategy for repairing LPHH remains disputable because no clear guidelines are given regarding indications, mesh type, shape or position. The aim of this study was to survey our short-term results of LPHH management with a biosynthetic monofilament polypropylene mesh coated with titanium dioxide to enhance biocompatibility (TiOMesh™).

Redo Surgery after Failure of Antireflux Surgery.

Surgery for refractory gastroesophageal reflux disease (GERD) has a satisfactory outcome for most patients; however, sometimes redo surgery is required. The Outcome and morbidity of a redo are suggested to be less successful than those of primary surgery. The aim of this study was to describe our experience, long-term results, and complications in redo surgery.

Outcomes of the Learning Curve in Our First 100 Consecutive Laparoscopic Gastrectomies.

Introduction: Laparoscopic surgery has been increasingly used for treatment of gastric cancer. However, standardization of this minimally invasive approach has not been reached yet because of its technical difficulties and the concern about oncological safety. The aim of the study was to analyze the outcomes of our learning curve in this complex surgical technique.

Comparison of Laparoscopic Versus Open Gastrectomy for Treatment of Gastric Cancer: Analysis of a Textbook Outcome.

Introduction: Open gastrectomy (OG) has long been the preferred surgical approach worldwide for treatment of gastric cancer (GC). Nowadays, several randomized prospective trials have confirmed improvements in postoperative outcomes for laparoscopic gastrectomy (LG) compared with open procedures, with similar oncologic outcomes. However, many of these studies come from Eastern countries.

Circulating adiponectin increases in obese women after sleeve gastrectomy or gastric bypass driving beneficial metabolic changes but with no relationship with carotid intima-media thickness.

Background & Aims: Obesity surgery induces beneficial effects in metabolic and cardiovascular parameters. Adiponectin increase might be associated with some of these changes. However, direct comparison between different surgical techniques has not been extensively performed.

Cytomegalovirus: associated ischemic colitis in an immunocompetent patient.

Cytomegalovirus (CMV) colitis is a common entity in immunocompromised patients, being rare among immunocompetent individuals. In addition, its association with ischemic colitis is unusual in both groups of population. Rectal bleeding might occur in both entities and, occasionally, urgent surgical treatment may be required, associating high morbility rates.

Portal Vein Thrombosis After Splenic and Pancreatic Surgery.

The portal vein is formed by the confluence of the splenic and superior mesenteric veins, which drain the spleen and small intestine respectively. Occlusion of the portal vein by thrombus typically occurs in patients with cirrhosis and/or prothrombotic disorders. However, portal vein thrombosis (PVT) can also happen after determined surgeries.

Duodenal fistula after gastrectomy: Retrospective study of 13 new cases.

Introduction: Duodenal stump fistula (DSF) after gastrectomy has a low incidence but a high morbidity and mortality, and is therefore one of the most aggressive and feared complications of this procedure.

Material And Methods: We retrospectively evaluated all DSF occurred at our hospital after carrying out a gastrectomy for gastric cancer, between January 1997 and December 2014. We analyzed demographic, oncologic, and surgical variables, and the evolution in terms of morbidity, mortality and hospital stay.

Comparative study between open and minimally invasive approach in the surgical management of esophageal leiomyoma.

Introduction: Leiomyomas are the most common benign tumors of the esophagus. Although classically surgical enucleation through thoracotomy or laparotomy has been widely accepted as treatment of choice, development of endoscopic and minimally invasive procedures has completely changed the surgical management of these tumors.

Material And Methods: We performed a retrospective review of all esophageal leiomyoma operated at Hospital Universitario Ramón y Cajal (Madrid, Spain) between January 1986 and December 2014, analyzing patients' demographic data, symptomatology, tumor size and location, diagnostic tests, surgical data, complications and postoperative stay.

Short- and mid-term changes in bone mineral density after laparoscopic sleeve gastrectomy.

Background: Bariatric surgery is the most effective treatment for achieving a significant weight loss. Morbidities present a significant reduction after bariatric surgery, but it may also result in several health complications, related to nutritional deficiencies, including bone metabolism. Several studies have reported a decrease in bone mineral density (BMD), but most of them referring to malabsorptive procedures.
