postoperative ileus

BACKGROUND: Postoperative ileus, driven by the cholinergic anti-inflammatory pathway, is the most common complication in patients undergoing colorectal surgery. By inhibiting acetylcholinesterase, pyridostigmine can potentially modulate the cholinergic anti-inflammatory pathway and accelerate gastrointestinal recovery. This study aimed to assess the efficacy of pyridostigmine in improving gastrointestinal recovery after colorectal surgery. METHODS: This double-blinded RCT enrolled adult patients undergoing elective colorectal surgery at two hospitals in South Australia...

AIM: To assess whether adults with diabetes on oral hypoglycaemic agents undergoing general endotracheal anaesthesia during nine common surgical procedures who are glucagon-like peptide-1 receptor agonist (GLP1-RA) users, compared with non-users, are at increased risk of six peri- and post-procedure complications. MATERIALS AND METHODS: A retrospective observational cohort analysis of over 130 million deidentified US adults with diabetes (defined as being on oral hypoglycaemic agents) from a nationally representative electronic health dataset between 1 January 2015 and 1 April 2023 was analysed...

BACKGROUND: Felcisetrag (5-hydroxytryptamine-4 receptor [5-HT4 ] agonist) is under investigation as prophylaxis or active treatment for accelerating resolution of gastrointestinal function post-surgery. METHODS: Phase 2, randomized, placebo-controlled, parallel five-arm, double-blind, multicenter study (NCT03827655) in 209 adults undergoing open or laparoscopic-assisted bowel surgery. Patients received intravenous placebo, felcisetrag 0.1 mg/100 ​mL or 0...

BACKGROUNDS: Strong evidence is lacking as no confirmatory randomized controlled trials (RCTs) have compared the efficacy of totally laparoscopic distal gastrectomy (TLDG) with laparoscopy-assisted distal gastrectomy (LADG). We performed an RCT to confirm if TLDG is different from LADG. METHODS: The XXXXX trial is a multicentre, open-label, parallel-group, phase III, RCT of 442 patients with clinical stage I gastric cancer. Patients were enrolled from 21 cancer care centers in South Korea between January 2018 and September 2020 and randomized to undergo TLDG or LADG using blocked randomization with a 1:1 allocation ratio, stratified by the participating investigators...

BACKGROUND: Postoperative ileus (POI) after colorectal surgery leads to increased morbidity, costs, and hospital stays. Identifying POI risk for early intervention is important for improving surgical outcomes especially given the increasing trend towards early discharge after surgery. While existing studies have assessed POI risk with regression models, the role of deep learning's remains unexplored. METHODS: We assessed the performance and transferability (brutal force/instance/parameter transfer) of Gated Recurrent Unit with Decay (GRU-D), a longitudinal deep learning architecture, for real-time risk assessment of POI among 7,349 colorectal surgeries performed across three hospital sites operated by Mayo Clinic with two electronic health records (EHR) systems...

Colorectal cancer (CRCa) is the most frequent gastrointestinal (GI) malignancy, while the liver is the most common site of distant metastases from CRCa, arising from hematogenous spread mainly via the portal venous system. The multiform nature of tumor presentation necessitates a comprehensive approach to diagnosis, perioperative care, and oncological treatment strategy. Herein, we present a case of a 76-year-old male patient diagnosed with obstructive bowel ileus due to a sigmoid tumor with synchronous, suspicious for metastasis, liver lesion who underwent Hartmann's sigmoidectomy in conjunction with left lateral hepatic resection at the same time...

BACKGROUND: The evolution of enhanced recovery pathways (ERPs) in colon and rectal surgery has led to the development of same-day discharge (SDD) procedures for selected patients. Early discharge after diverting loop ileostomy (DLI) closure was first described in 2003. However, its widespread adoption remains limited, with SDD accounting for only 3.2% of all DLI closures in 2005-2006, according to the American College of Surgeons National Surgical Quality Improvement Program database, and rising to just 4...

BACKGROUND: Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is associated with significant morbidity and mortality. We present an alternative technique that preserves the complete mesenteric vascularization during the isolation of the intestinal segment used in ICUD, including distal vessels. This approach aims to minimize the risk of ischemia in both the ileal anastomosis and the isolated loop at the diversion site. METHODS: This cohort study included 31 patients, both male and female, who underwent RARC with ICUD from February 2018 to November 2023, performed by a single surgeon...

Postoperative ileus (POI) after colorectal surgery is a major problem that affects both patient recovery and hospital costs highlighting the importance of preventive strategies. Therefore, we aimed to perform a systematic analysis of the effects of postoperative caffeine consumption on bowel recovery and surgical morbidity after colorectal surgery. A comprehensive literature search was conducted through September 2023 for randomized and non-randomized trials comparing the effect of caffeinated versus non-caffeinated drinks on POI by evaluating bowel movement resumption, time to first flatus and solid food intake, and length of hospital stay (LOS)...

AIM: Prolonged postoperative ileus (PPOI) is common and is associated with a significant healthcare burden. Previous studies have attempted to predict PPOI clinically using risk prediction algorithms. The aim of this work was to systematically review and compare risk prediction algorithms for PPOI following colorectal surgery. METHOD: A systematic literature search was conducted using MEDLINE, Embase, Web of Science and CINAHL Plus. Studies that developed and/or validated a risk prediction algorithm for PPOI in adults following colorectal surgery were included...

BACKGROUND: Postoperative ileus (POI) continues to be a major cause of morbidity following colorectal surgery. Despite best efforts, the incidence of POI in colorectal surgery remains high (~30%). This study aimed to investigate machine learning techniques to identify risk factors for POI in colorectal surgery patients, to help guide further preventative strategies. METHODS: A TRIPOD-guideline-compliant retrospective study was conducted for major colorectal surgery patients at a single tertial care centre (2018-2022)...

BACKGROUND: Colorectal cancer is among the most common cancers in the world, and splenic flexure colon cancer accounts for about 2-5% of them. There is still no consensus on the surgical treatment of splenic flexure colon cancer (SFCC), and the extent of surgical resection and lymph node dissection for SFCC is still controversial. AIM: To compare the postoperative and long-term oncologic outcomes of extended right colectomy (ERC), segmental colectomy (SC) and left colectomy (LC) for SFCC...

INTRODUCTION: Cutaneous ureterostomy is beneficial for older patients in a hypoalimentation state, providing less invasive options than intestinal tract reconstruction techniques. However, complications such as ileus and stoma site hernia still pose risks owing to the anatomical location of the ureter. We introduce a novel method, complete retroperitoneal cutaneous ureterostomy, performed simultaneously with robot-assisted radical cystectomy. CASE PRESENTATION: Our technique involves extending the retroperitoneal space to minimize complications and achieve stent-free outcomes...

BACKGROUND AND OBJECTIVE: Hypogonadism and frailty may impact postoperative outcomes for men undergoing radical nephrectomy (RN). We aimed to determine the prevalence of hypogonadism in men undergoing RN and whether hypogonadism and frailty are associated with adverse postoperative outcomes. METHODS: We identified men undergoing RN between 2012 and 2021 using the IBM Marketscan database. Frailty was determined using the Hospital Frailty Risk Score (HFRS). Patients were considered to have hypogonadism if diagnosed <5 years before RN...

Subcutaneous emphysema, the presence of air in the subcutaneous layer of the skin, is a possible result of surgical, infectious, or spontaneous etiologies. Although usually self-limiting, the development of subcutaneous emphysema in the perioperative period has been associated with delayed extubation and the development of complications such as pneumomediastinum, pneumoperitoneum, and pneumothorax and can worsen clinical outcomes in these patients. Here, we report the case of a 57-year-old male patient who presented to the operating room (OR) for a robotic total colectomy due to Lynch syndrome...

BACKGROUND: There is still a controversy about the superiority of liposomal bupivacaine (LB) over traditional local anesthetics in postoperative analgesia after thoracic surgery. This study aims to determine the effect of LB versus bupivacaine hydrochloride (HCl) for preoperative ultrasound-guided erector spinae plane block (ESPB) on postoperative acute and chronic pain in patients undergoing video-assisted thoracoscopic lung surgery. METHODS: This multicenter, randomized, double-blind, controlled trial will include 272 adult patients scheduled for elective video-assisted thoracoscopic lung surgery...

PURPOSE: No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. MATERIALS AND METHODS: 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1 year for survivors...
