BACKGROUND: Our primary objective was to demonstrate the utility and feasibility of intraoperative assessment colon rectal perfusion using fluorescence angiography (FA) during left-sided colectomy anterior resection. Anastomotic leak (AL) after colorectal resection increases morbidity, mortality, and, in cancer cases, recurrence rates. Inadequate may contribute AL. The PINPOINT Endoscopic Fluorescence Imaging System allows for anastomotic perfusion. STUDY DESIGN: This is a prospective,...

The purpose of this study was to identify patient, clinical, and surgical factors that may predispose patients anastomotic leak (AL) after large bowel surgery.Anastomotic is still one the most devastating complications following colorectal surgery. Knowledge about predisposing AL vital its early detection, decision making for time, managing preoperative risk factors, postoperative complications.This a prospective observational, quality improvement in cohort 616 undergoing resection single...

This study was designed to compare short-term outcomes after hand-assisted laparoscopic vs. straight colorectal surgery.Eleven surgeons at five centers participated in a prospective, randomized trial of patients undergoing elective sigmoid/left colectomy and total colectomy. The powered detect 30-minute reduction operative time between groups.There were 47 (33 colectomy, 14 colectomy) 48 15 colectomy). There no differences the patient age, sex, body mass index, previous surgery, diagnosis,...

Patients with large benign colon polyps not amenable to endoscopic removal commonly undergo resections. Polyp using combined endolaparoscopic surgery may be an effective alternative bowel resection in select patients.The aim of this study was evaluate short-term and long-term outcomes patients who underwent endolaparoscopy at our institution.Medical records a prospectively maintained database were reviewed.This constituted retrospective review consecutive for from 2003 2012.Combined...

Laparoscopic surgical treatment of T4 cancers remains a concern that is mostly associated with technical feasibility, high conversion rate, inadequate oncologic clearance, and outcome.The purpose this work was to evaluate the short- long-term clinical outcomes after laparoscopic open surgeries for colon cancers.This retrospective study patients cancer without metastasis (M0) who had or surgery from 2003 2011.The conducted at single institution.A total 83 pT4 were included.R0 resection...

PURPOSE COVID-19 has infected more than 94 million people worldwide and caused 2 deaths. Patients with cancer are at significantly increased risk compared the general population. Telemedicine represents a common strategy to prevent viral spread. We sought evaluate patient physician perceptions of telemedicine during pandemic. METHODS A 16-question survey was e-mailed 1,843 active e-mails patients presenting one six clinics comprehensive care center from January 1, 2020, June 2020....

PURPOSE: The use of laparoscopy surgery in the management rectal cancer is controversial, especially mid and low rectum. aim this study was to determine oncologic long-term outcomes after laparoscopic hand-assisted for cancer. METHODS: Between January 1999 December 2006, 185 patients had cancer; 103 these source data inpatient/outpatient medical records. Telephone interviews were conducted all patients. Actuarial survival calculated with Kaplan-Meier method. RESULTS: Hand-assisted performed...

For complex right colon polyps, not removable using colonoscopy, resection is considered the optimal treatment. Combined endoscopic-laparoscopic surgery, both laparoscopy and CO2 has been introduced as a new approach for these polyps with intent to avoid bowel resection.This study aimed evaluate safety outcomes of combined surgery used treatment polyps.This retrospective patients undergoing benign from 2003 2008.This single-institution study.Twenty-three were included.The main outcome...

Although reflux esophagitis is believed to be common in the Western population, very few epidemiologic data on Koreans are available. The aims of this study were evaluate prevalence endoscopic patients who came for a physical check-up at Korea University Hospital, and relationship between various factors relevant disease.This was carried out prospectively 7,015 received an esophagogastroduodenoscopy from September 1996 December 1997. Most free symptoms had come their self-paid check-up.The...

PURPOSE: Mouse mammary carcinoma tumors are established more easily and grow larger after sham laparotomy open bowel resection than CO2 pneumoperitoneum laparoscopic-assisted resection. The purpose of this study was to determine whether similar differences in tumor growth would be found when were compared for the colon-26 mouse adenocarcinoma B-16 melanoma lines. METHODS: In all three studies, a high-dose injection cells used, which resulted almost control mice. Study 1, female BALB/C mice...

Most of the recent color recognition/indexing approaches concentrate on establishing invariance to illumination improve utility recognition. However, other effects caused by pose and specularity three-dimensional object surfaces have not received notable attention. We present a chromaticity recognition method that discounts pose, specularity. It utilizes space based log-ratio sensor responses for invariance. A model-based detection/rejection algorithm can be used estimation objects including...

The study investigated the impact of prior abdominal surgery on conversions and outcomes laparoscopic right colectomy.A consecutive series 414 patients with cancer or adenomas who underwent a colectomy from March 1996 to November 2006 were studied for surgical outcomes. Conversion was defined as an incision length > 7 cm.Patients (n = 191) compared no 223), showed significant differences in age, ASA classification, stay, operative time, blood loss, harvested nodes, tumor size, specimen...

This paper investigates the use of photometric features for pair-wise registration range images. Many artificial and natural objects exhibit abundant surface texture that may not be revealed in data, most structured light laser sensors are capable capturing either grayscale or color intensity addition to data. Nevertheless, has been widely investigated data registration, despite widespread research into local feature descriptors object recognition 2D addresses some problems arise using...

Our laboratory has previously shown that tumors are more easily established and grow larger after laparotomy vs. laparoscopy. The purpose of this study was to better characterize these differences in tumor growth by assessing cell proliferation via the proliferating nuclear antigen assay, which been be a reliable marker cellular proliferation.Female C3H/He mice (N = 40) were inoculated intradermally dorsal skin with 10(6) cultured mouse mammary carcinoma cells <1 hour before interventions....

The distribution of object colors can be effectively utilized for recognition and indexing. Difficulties arise in the color distributions when there are variations illumination changes pose with respect to direction, specular reflections. However, most recent approaches color-based focus mainly on invariance. authors propose an approach that identifies influenced by: (1) pose, (2) (3) specularity. They suggest use chromaticity achieve To characterize due a set histograms each is generated...

Benign colon polyps are commonly encountered but may not always be amenable to endoscopic excision because of their size, shape, location, or scarring from previous attempts. The addition laparoscopy allows a greater degree bowel manipulation, the current technique is still limited when encountering polyp with inadequate lifting attributed morphology scarring. We describe an extension existing combined laparoscopic surgery using full-thickness approach increase maneuverability and local...

A prospectively maintained database of 415 patients undergoing colectomy was evaluated. We performed a logistic regression analysis to identify factors associated with 1) length stay (LOS) 2 days or less and 2) LOS 10 more. Investigated variables included demographics, American Society Anesthesiology (ASA) score, diagnosis, operative procedure, approach time, transfusion requirements, occurrence any complications. Factors two ASA [odds ratio (OR): 0.34, 95% confidence interval (CI):...

Surgeons have experienced an increase in the number of patients referred for management endoscopically unresectable colon polyps as a result increased adoption colonoscopy-based cancer screening. The majority these historically received recommendation to undergo oncologic resection, exposing them significant operative and long-term morbidity. Combined endoscopic laparoscopic surgery (CELS) techniques since been developed leverage unique advantages two separate approaches allow colon-sparing...
