This study aimed to determine the role of CRP as an early predictor PCs a reliable discharge indicator gastrectomy.Clinicopathologic data 613 patients who underwent for gastric cancer in 2015-2016 were retrospectively analyzed, including consecutive blood samples obtained preoperatively, at operative day, postoperatively. Following Clavien-Dindo classification, divided into group...
Abstract Background Petersen’s hernia, which occurs after Billroth-II (B-II) or Roux-en-Y (REY) anastomosis, can be reduced by defect closure. This study aims to compare the incidence of bowel obstruction above Clavien–Dindo classification grade III due hernia between mesenteric fixation method and conventional methods laparoscopic robotic gastrectomy. Methods was designed as prospective, single-blind, non-inferiority randomized controlled multicenter trial in Korea. Patients with...
The selection of the appropriate treatment strategy for patients with mucosal gastric cancer (MGC) remains controversial. In present study, we aimed to determine risk factors lymph node (LN) metastasis in MGC and reassess role endoscopic submucosal dissection (ESD).We examined 1,191 who underwent curative gastrectomy between January 2005 December 2014. We determined clinicopathologic LN among patients.Among MGC, 42 (3.5%) had metastasis. Univariate analysis indicated that age ≤ 50 years (P =...
Abstract Background Previous studies have focused on the non-inferiority of RPG compared with conventional port gastrectomy (CPG); however, we assumed that some candidates might derive more significant benefit from over CPG. Methods We retrospectively analyzed clinicopathological and perioperative parameters 1442 patients gastric cancer treated by between 2009 2022. The C-reactive protein level postoperative day 3 (CRPD3) was used as a surrogate parameter for surgical trauma. Patients were...
This study introduces a novel technique for liver retraction during laparoscopic gastrectomy and assesses its impact on postoperative recovery. included 139 patients in whom Nelaton catheters (n=57) or Nathanson retractors (n=82) were used retraction. Serum enzyme levels measured preoperatively the first, second, third, fifth, seventh days. Clinicopathologic features recovery variables between 2 groups compared. The aspartate aminotransferase, alanine C-reactive protein significantly lower (...
Compensation for increased medical services from reimbursement systems are sometimes insufficient. Generally, appendectomies performed by individual surgeons with their preferred instrument. Surgical equipment standardization is known to reduce cost without compromising patient safety. Hence, we investigated the effectiveness of surgical required operative laparoscopic appendectomy at our tertiary hospital.Nine hospital agreed use standardized appendectomy. We compared outcomes among...
The use of naturally sourced organic materials with chirality, such as the M13 bacteriophage, holds intriguing implications, especially in field nanotechnology. chirality properties bacteriophages have been demonstrated through numerous studies, particularly analysis liquid crystal phase transitions, developing specific applications. However, exploring utilization bacteriophage a template for creating chiral nanostructures optics and sensor applications comes significant challenges. In this...
Endoscopic submucosal dissection (ESD) plays a pivotal role in treating early gastric cancer (EGC). Some patients require additional gastrectomy because of non-curative ESD. This study aimed to analyze the clinical factors associated with ESD and re-evaluate according its indication criteria. Altogether, 134 who had undergone lymphadenectomy for based on pathological results specimens were included. Their data including pre-ESD diagnosis, reasons requesting gastrectomy, surgical outcomes...
The aim of this study was to analyze the effects reduced fasting time on postoperative recovery in patients who underwent totally laparoscopic distal gastrectomy (TLDG).This retrospective included 347 TLDG. Patients were divided into 2 groups: group (n = 139) and conventional feeding 208). We compared total hospital cost parameters, such as complications, mean stay, day first flatus, initiation soft diet, serum CRP levels, between groups.The had a lower (P < 0.001) than group. Regarding...
Torsion of the appendix is rare, and appendiceal mucocele can be one its causes. The first case was a 49-year-old man who visited emergency room (ER) for abdominal pain. Abdominal computed tomography (CT) showed with suspected torsion rupture. patient underwent laparoscopic exploration appendectomy. second 69-year-old ER epigastric CT suspicious ischemic change, indicating appendix. twisted successfully removed by exploration. An causes With torsion, diagnosed as rupture ischemia which may...
Mucinous gastric adenocarcinoma (MGC) is defined by the World Health Organization as a with >50% extracellular mucin pools within tumors. In this study, we attempted to analyze clinicopathologic features of patients pathologically diagnosed cancer lower than 50% tumor volume pool (LEMPC). We compared MGC versus nonmucinous (NMGC). were used in abbreviations LEMPC for NMGC including pool.Files 995 (n = 935), 20), 40) who underwent curative resection at Pusan National University Yangsan...
We report a case of 65 years old man who was found on routine esophagogastroduodenoscopy to have gastric tumour. Histology revealed adenocarcinoma. Staging investigation with abdominal computed tomography (CT) confirmed cancer the antrum lymph node enlargement at hepato-duodenal ligament.
