Laparoscopic Sleeve Gastrectomy has A Positive Impact on Subclinical Hypothyroidism Among Obese Patients: A Prospective Study
In this study, we aimed to evaluate the changes in thyroid functions after gastric sleeve operation for morbidly obese Egyptian patients.MethodsThis was a prospective study that recruited 128 patients who underwent sleeve gastrectomy through the period from December 2016 to April 2020. We measured thyroid-stimulating hormone (TSH), free thyroxin (FT4), and free triiodothyronine. Subclinical hypothyroidism was defined by a TSH level  >  4.5 mIU/L but a normal FT4 level. All patients were followed for 12 months after the procedure.ResultsPreoperatively, 30 (23.4%) patients had subclinical hypothyroidism...

Surgical Resection of Tumors Invading the Inferior Vena Cava at the Hepatic Vein and Thoracic Levels
AbstractBackgroundOur aim was to describe the results of our program of surgical resection of tumors invading the inferior vena cava (IVC) at the hepatic and thoracic levels. We hypothesized that similar surgical outcomes may be obtained compared to tumor resection below the hepatic vein level if the liver function was preserved.MethodsWe performed a single-center retrospective study of 72 consecutive patients who underwent surgical resection from 1996 to 2019 for tumors invading the IVC. We compared two groups based on tumor location below (group I/II) or above (group III/IV) the inferior limit of hepatic veins.ResultsTum...

Prognostic Significance of Preoperative Osteopenia in Patients Undergoing Esophagectomy for Esophageal Cancer
AbstractBackgroundOsteopenia, which exhibits low bone mineral density (BMD), has been linked to sarcopenia and recently reported as a prognostic factor in various cancers. However, the prognostic significance of osteopenia in esophageal cancer remains unclear. Hence, this study aimed to clarify the impact of osteopenia on the prognosis of patients undergoing esophagectomy for esophageal cancer.MethodsWe included 229 patients who underwent esophagectomy. BMD was calculated as the average pixel density (Hounsfield unit) within a circle in midvertebral core at the 11th thoracic vertebra on preoperative computed tomography. We...

Management of Morgagni ’s Hernia in the Adult Population: A Systematic Review of the Literature
ConclusionsMH is a rare type of congenital diaphragmatic hernia which rarely manifests in adult population with atypical pulmonary and gastrointestinal symptoms. Surgery is the gold standard for their management. Open surgical approach is preferable in emergency cases, while laparoscopic surgery is favored in elective setting and is associated with shorter hospitalization. Further studies are crucial in order to elucidate etiology and optimal therapeutic approach. (Source: World Journal of Surgery)

Cholangiojejunostomy Using a Novel Magnamosis Device: Initial Clinical Results
AbstractBackgroundCholangiojejunostomy (CJ) is a popular operation; however, no specific anastomotic device is available. A novel magnamosis device for CJ was developed in 2017; here, we evaluated the feasibility and safety of the device.MethodsBetween January 2017 and December 2019, 23 patients who underwent CJ using a novel magnamosis device were enrolled. For the CJ: the parent magnet was placed in the proximal duct, and the purse –string suture was tightened over the rod of the parent magnet. The magnamosis device was introduced into the jejunum, and the mandrel penetrated the jejunum at the anastomotic site, bef...

Impact of 2016 Enhanced Recovery After Surgery (ERAS) Recommendations on Outcomes after Hepatectomy in Cirrhotic and Non-Cirrhotic Patients
AbstractBackgroundThe Enhanced Recovery After Surgery (ERAS) society published new recommendations for hepatectomy in 2016. Few studies have assessed their clinical impact. The aim of this monocentric study was to assess the impact of those guidelines on outcomes after liver surgery with a special focus on cirrhotic patients.MethodPostoperative outcomes of patients undergoing hepatectomy 30  months before and after ERAS implementation according to the 2016 ERAS guidelines were compared after inverse probability of treatment weighting (IPTW). Primary endpoint was 90-day morbidity.ResultsFrom 2015 to 2020, 430 patients ...

We Asked the Experts: The Role of Rural Hospitals in Achieving Equitable Surgical Access in Low-Resourced Settings
AbstractStrengthening and defining the role of rural hospitals within a surgical ecosystem is essential to improving quality and timely surgical access for rural people in low and middle-income countries (LMICs). Regional hospitals are the cornerstone of LMIC rural surgical care but have insufficient human resources and infrastructure that limit the surgical care they can provide. District hospitals are most accessible for many rural patients but also have limited surgical capacity. In order to surgical access for rural people, both regional and district hospital surgical services must be strengthened. A strong relationshi...
