INTRODUCTION: We previously developed risk models for mortality and morbidity after low anterior resection using a nationwide Japanese database. However, the milieu of low anterior resection in Japan has undergone drastic changes since then. This study aimed to construct risk models for 6 short-term postoperative outcomes after low anterior resection, i.e., in-hospital mortality, 30-day mortality, anastomotic leakage, surgical site infection except for anastomotic leakage, overall postoperative complication rate, and 30-day reoperation rate...

INTRODUCTION: Complicated appendicitis (CA) is often indicated for emergency surgery; however, preoperative predictors of pathological complicated appendicitis (pCA) remain unclear. Furthermore, characteristics of CA that can be treated conservatively have not yet been established. METHODS: Three hundred and five consecutive patients diagnosed with acute appendicitis were reviewed. The patients were divided into two groups: an emergency surgery and a conservative treatment group...

INTRODUCTION: This study aimed to evaluate the use of LC operative time (CholeS score) and conversion to an open procedure (CLOC score) outside their validation dataset in Mexican population. METHODS: Patients >18 years who underwent elective LC were analyzed in a single-center retrospective chart review study. Association between scores (CholeS and CLOC) with operative time and conversion to open procedures was assessed with Spearman correlation. The predictive accuracy of the CholeS Score and CLOC score was evaluated by Receiver Operator Characteristic (ROC)...

INTRODUCTION: Curative therapy for gastric cancer usually consists of perioperative chemotherapy combined with a radical (R0) gastrectomy. In addition to a modified D2-lymphadenectony, a complete omentectomy is recommended. However, there is little evidence for a survival benefit of omentectomy. This study presents the follow-up data of the OMEGA-study. METHODS: This multicenter prospective cohort study included 100 consecutive patients with gastric cancer undergoing (sub)total gastrectomy with complete en bloc omentectomy and modified D2 lymphadenectomy...

Introduction The beneficial effects of exercise and physical activity (PA) have been demonstrated in many chronic inflammatory diseases. Knowledge on physical activity levels is unknown in the chronic pancreatitis population and there are currently no specific PA recommendations for this condition. Methods Physical activity was measured objectively over a 7- day period in 17 individuals with chronic pancreatitis using an accelerometer (Acti-graph) and in 15 controls, matched for age, sex, and body mass index...

Introduction Laparoscopic low anterior resection (L-LAR) has become widely accepted for the treatment of rectal cancer. However, little is known about the superiority of L-LAR in a real-world setting (including low-volume hospitals) and the association between the short-term outcomes and hospital volume focusing on L-LAR. Methods This is a retrospective cohort study. A total of 37,821 patients who underwent LAR for rectal cancer were analyzed using the Diagnosis Procedure Combination (DPC) database from January 2014 to December 2017...

BACKGROUND: Neoadjuvant treatment is currently the gold standard for advanced esophageal squamous cell carcinoma (ESCC). Several studies have examined the value of blood count-based indexes for predicting short- and long-term outcomes after esophagectomy for ESCC, but the relative predictive value of pretreatment, preoperative, and postoperative indexes has not yet been examined. METHODS: This study included 320 patients with thoracic ESCC who underwent subtotal esophagectomy after neoadjuvant chemotherapy or chemoradiotherapy at our institution...

INTRODUCTION: The balance between potential oncological merits and surgical risks is unclear for the additional step of performing paratracheal lymphadenectomy during esophagectomy for cancer. This study aimed to investigate the impact of paratracheal lymphadenectomy on lymph node yield and short-term outcomes in patients who underwent this procedure in The Netherlands. METHODS: Patients who underwent neoadjuvant chemoradiotherapy followed by transthoracic esophagectomy were included from the Dutch Upper Gastrointestinal Cancer Audit (DUCA)...

We report a case of pathologic complete response after successful treatment for advanced hepatocellular carcinoma (HCC) complicated with portal venous tumor thrombus by atezolizumab and bevacizumab followed by radical resection. The patient was a male in his 60s. During follow-up for chronic hepatitis B, abdominal ultrasonography revealed a huge tumor located in the right lobe of the liver with the portal vein thrombosed by the tumor. The tumor thrombus extended to the proximal side of the left branch of the portal vein...

INTRODUCTION: A systematic review of the literature was carried out to determine the clinical and oncological outcome of patients who had enucleation of solitary pancreatic metastases from renal cell carcinoma. METHODS: Operative mortality, postoperative complications, observed survival and disease free survival were analyzed. The clinical outcomes of patients who had enucleation were compared to those of 857 patients collected from the literature who had standard or atypical pancreatic resection for the same disease using propensity score matching Results: There was no postoperative mortality in the 56 patients who had enucleation of pancreatic metastases from renal cell carcinoma ...

Background Due to weight regain and GIT symptoms associated with Vertical banded gastroplasty (VBG) revisional surgery is necessary, Roux-en-Y gastric bypass (RYGB) is one of the best options as a revision procedure but comes with a high complication rate. Methods This prospective study included eighty patients undergoing Roux-en-Y gastric bypass surgery at Ain Shams University Hospitals after failed VBG surgery, with up to 2 years of follow-up. Results Eighty patients underwent RYGB correction after VBG. The mean age was 42 ±6...

INTRODUCTION: In 15% of patients with iron deficiency anemia, large diaphragmatic hernias are found as the cause of chronic iron loss. Conversely, iron deficiency anemia is present in 10-40% of diaphragmatic hernia patients. However, it is unclear why some patients with large diaphragmatic hernias develop anemia and others do not. METHODS: We retrospectively analyzed 116 patients with diaphragmatic hernias larger than 5 cm for the presence of anemia and the effect of surgery on this anemia, dividing these patients into 4 groups (group A: 21 patients with anemia/surgery, group B: 27 patients without anemia but with surgery, group C: 34 patients with anemia but without surgery, group D: 34 patients without anemia/surgery)...

INTRODUCTION: RCTs support neoadjuvant chemoradiotherapy (nCRT) followed by surgery in Locally Advanced Esophago-Gastric Junction (LA-EGJ) adenocarcinoma. However, RCTs are performed in highly controlled settings with limited representativeness of real-life patients (RLS). AIM: To compare the outcomes in RLS and clinical trial settings. METHODS: The outcomes of RLS, which comprised 125 patients consequently treated for LA-EGJ adenocarcinoma between 2012 and 2017, were compared with the phase II trial (PIIS), performed on 65 patients from 2003 to 2011...

INTRODUCTION: Currently, the rate of bile duct injury and leak following laparoscopic cholecystectomy (LC) is still higher than for open surgery. Diverse investigative algorithms were suggested for bile leak, shifting from hepatobiliary scintigraphy (HBS) toward invasive and more sophisticated means. We aimed to analyze the use of biliary scan as the initial modality to investigate significant bile leak in the drain following LC, attempting to avoid potential unnecessary invasive means when the scan demonstrate fair passage of nuclear substance to the intestine, without leak...

INTRODUCTION: Hepatic artery anomalies (HAA) may have an impact on surgical and oncological outcomes of patients undergoing pancreaticoduodenectomy (PD). METHODS: Patients who underwent PD at our institution between July 2015 and January 2020 were retrospectively reviewed and classified into two groups: group 1, with presence of HAA, and group 2, with no HAA. A weighted logistic regression model was employed to assess the association between HAA and postoperative complications, and to assess the association between HAA and R status in patients with pancreatic cancer...

INTRODUCTION: Thyroid incidentalomas are often encountered during imaging performed for the workup of esophageal cancer. Their oncological significance is unknown. This study aimed to establish incidence and etiology of thyroid incidentalomas found during the diagnostic workup of esophageal cancer. METHODS: All esophageal cancer patients referred to or diagnosed at the Amsterdam UMC between January 2012 and December 2016 were included. Radiology and multidisciplinary team meeting reports were reviewed for presence of thyroid incidentalomas...

INTRODUCTION: Hiatal hernia repair is associated with substantial recurrence of both hiatal hernia and symptoms of gastroesophageal reflux (GER). While small randomized controlled trials demonstrate limited differences in outcomes with use of mesh or fundoplication type, uncertainty remains. METHODS: A multicenter, retrospective review of patients undergoing surgical treatment of hiatal hernias between 2015 and 2020 was performed. Patients with mesh and with suture-only repair were compared, and partial versus complete fundoplication was compared...

Robot-assisted pancreatoduodenectomy (R-PD) may provide challenges but potential benefits for pancreatic-enteric anastomosis fashioning. Despite numerous trials comparing different pancreatic-enteric anastomosis techniques, an ideal method is still missing. This study aims to describe different management strategies and surgical techniques of standardized pancreatic-enteric anastomoses during an R-PD. This study reported the robotic technical steps of the modified end-to-side Blumgart pancreaticojejunostomy, the Cattel-Warren duct-to-mucosa pancreatojejunostomy, with internal or external pancreatic duct stent, and the modified end-to-side, double-layer pancreogastrostomy...

We report a new surgical method in 10 patients that underwent hybrid laparo-endoscopic resection (HLER) of submucosal tumors with the combination of flexible articulated laparoscopic instruments (FALI). We have assessed technical reproducibility, safety and morbidity. Resection was completed in all cases. Mean surgical time was 60 minutes (30-85). Median tumor size was 16 mm (12-30). The more frequent location was gastroesophageal junction. No complications were observed during the procedure. Length of stay was 1 day in all cases...
