Omental wrapping

BACKGROUND: Fungal prosthetic graft infections are associated with high mortality, typically requiring aggressive surgical debridement. We present an alternative, minimally invasive approach to address these challenging clinical cases. CASE PRESENTATION: A 76-year-old Caucasian male with prior aortic root and arch replacement presented with localized chest wall tenderness after being hit by a car door. Computed tomography angiogram incidentally identified fluid in the anterior mediastinum, surrounding his ascending aortic graft...

BACKGROUND: Despite obvious advantages of peritoneal dialysis (PD), mechanical complications are responsible for the failure of PD at early stage. Suture fixation in laparoscopic PD catheter method could reduce mechanical complications. In our study, a simple method to fix PD catheter was developed. METHODS: Tenckhoff catheter placement was performed in 49 consecutive patients. In the technique, only two trocars were used. With the help of syringe needle and forceps, a loop of silk was prepared at the abdominal wall...

Objective: To evaluate the role of heart rate variability (HRV) in predicting pre-operative severity of appendicitis. Methods: In this cross-sectional study, 171 cases of acute appendicitis who underwent appendectomy were enrolled. Pre-anesthetic pulse rate of included patients were documented while the severity of appendicitis was determined by intra-operative evidences reported by two independent surgeons. Demographic characteristics, laboratory variables, and Alvarado criteria were recorded...

BACKGROUND: To explore the application value of free omental wrapping and modified pancreaticojejunostomy in pancreaticoduodenectomy (PD). METHODS: The clinical data of 175 patients who underwent pancreaticoduodenectomy from January 2015 to December 2020 were retrospectively analysed. In total, 86 cases were divided into Group A (omental wrapping and modified pancreaticojejunostomy) and 89 cases were divided into Group B (control group). The incidences of postoperative pancreatic fistula and other complications were compared between the two groups, and univariate and multivariate logistic regression analyses were used to determine the potential risk factors for postoperative pancreatic fistula...

BACKGROUND: Peritoneal dialysis (PD) is an excellent, but underutilized dialysis technique. Thus, its implementation may depend also on the chance to offer this modality of treatment to patients referred late to the nephologists. This approach has recently been named "urgent-start peritoneal dialysis" (UPD). The main barrier to this practice is represented by the fear of early mechanical complications. METHODS: All prevalent patients needing urgent-start PD at our institution between 1 January, 2009 and 31 December, 2019 were included in the study...

BACKGROUND: Robot-assisted autologous graft ureteroplasty provides another treatment option for complex ureteral strictures, circumventing ileal ureter or renal autotransplantation. OBJECTIVE: To report the medium-term outcome of robotic ureteroplasty with a lingual mucosal graft (RU-LMG) for managing complex ureteral strictures. DESIGN, SETTING, AND PARTICIPANTS: Between June 2019 and September 2020, 12 patients underwent RU-LMG. The perioperative variables were prospectively collected, and the outcomes were assessed...

OBJECTIVES: Peritoneal dialysis (PD) is an option for ultrafiltration for patients with end-stage renal disease. Once placed, PD catheters may malfunction often due to omental wrapping. Omental procedures such as omentectomy and omentopexy may reduce this risk. This investigation aims to perform a systematic review and meta-analysis of the literature on the role of omental procedures on PD catheter insertions. METHODS: Following protocol registration on PROSPERO (CRD42020218950), a systematic review was performed in accordance with the Cochrane Collaboration...

Background: Catheter malfunction is a common complication of peritoneal dialysis (PD). This study aimed to retrospectively analyze the risk factors and management of catheter malfunction in urgent-start PD. Methods: Patients who underwent urgent-start PD were divided into catheter-malfunction and control groups. Baseline demographic and laboratory data of the two groups were compared, and the risk factors for catheter malfunction were analyzed. Primary outcome measure was catheter survival, and the secondary outcomes were surgical complications and malfunction treatment...

Various types of thin flaps have been used for reconstruction in cases of complete circumferential degloving injuries of digits (Urbaniak classification class III). The omental flap has extensive, pliable, and well-vascularized tissue and helps prevent bone resorption of the distal phalange that can result from avascular necrosis. A 31-year-old right-handed man with class III left thumb injury and compartment syndrome of the left forearm was treated successfully with a free omental flap wrapped around the thumb and then covered with a tubular split-thickness skin graft...

BACKGROUND: Peritoneal dialysis (PD) catheters can be obstructed by omental wrapping or migration, leading to catheter malfunction. Multiple catheter placement techniques have been described. Advanced laparoscopy with fixation of the catheter and omentum has been reported to improve functional outcome compared to basic laparoscopy without fixation. This feasibility study describes surgical technique, complications, and comparison of the functional outcome of advanced versus basic laparoscopic catheter placement...

We describe a case of an elderly man with Citrobacter freundii -associated infectious rupture of a dissecting thoracoabdominal aortic aneurysm. We performed an emergency thoracoabdominal aortic replacement using a rifampicin-soaked prosthetic graft and omental flap wrapping. The patient was discharged on postoperative day 255, although he experienced pseudomembranous enteritis and paraplegia.

Background: To present our experience with the "omental wrapping" technique in laparoscopic and robotic ureteroplasty using onlay flaps or grafts for the management of long proximal or middle ureteral strictures. Methods: This is a retrospective review of 25 patients with long proximal or middle ureteral strictures who underwent laparoscopic and robotic onlay flaps or grafts ureteroplasty using an omental flap to reinforce an anastomosis site between August 2018 and November 2019...

Dialysis patients have an increased risk of coronavirus disease 2019 (COVID-19)-related mortality. Acute heart failure is a frequent, lethal complication of COVID-19, and it is a risk factor for mortality in hemodialysis patients. Therefore, it is crucial to rapidly distinguish heart failure from COVID-19 pneumonia. Here, we report a case of two episodes of acute dyspnea that were induced by COVID-19 in a peritoneal dialysis (PD) patient. The first episode of acute dyspnea was an exacerbation of heart failure caused by COVID-19 when the patient had a volume overload status due to a peritoneal dialysis catheter malfunction...

A ruptured infrarenal abdominal aortic aneurysm (rAAA) is associated with an in-hospital mortality rate of 40% and an overall mortality rate of 60-80%. Open surgical repair for rAAA remains the principal method of treatment when endovascular repair is not available. Graft infection occurs in 1-4% of patients at 5 years, with a high incidence following emergency treatment. Other graft-related complications include pseudoaneurysm, graft occlusion and aorto-enteric fistula. This case report describes a 66-year-old male patient that was admitted to hospital complaining of intense abdominal pain, low blood pressure and tachycardia...

Carinal reconstruction and omental flap harvesting are traditionally performed via open approaches. We reported a case in which carinal reconstruction with bronchial flap and omental flap reinforcement was performed using minimally invasive approaches. The omental flap was harvested laparoscopically, and wrapped around the anastomosis, which reduced the risk of airway anastomosis complications. Non-circumferential resection and reconstruction used bronchial flap, which made it easier to perform under video-assisted thoracoscopic surgery conditions...

Percutaneous peritoneal dialysis catheter (PDC) insertion for continuous ambulatory peritoneal dialysis (CAPD) entails a higher risk of complications such as bowel injury, vascular injury, and catheter migration compared to the surgical insertions. We conducted a comparative analysis of two techniques of peritoneal entry for PDC insertion by Seldinger technique. We performed a retrospective review of 426 percutaneously inserted PDCs in nonobese naïve abdomens for CAPD at two tertiary care teaching hospitals in India over 6 years...

Introduction: Alarming outcomes have been reported following infected endovascular aortic aneurysm repair (EVAR) device explantation. Infected fenestrated EVAR (FEVAR) exposes patients to even worse procedural risks. Report: A 67 year old man with a prior history of FEVAR presented with impaired general condition, abdominal and back pain, and increased C reactive protein. Computed tomography angiography revealed a collection around the aortic graft bifurcation and 18 F-fluorodeoxyglucose-positron emission tomography (FDG-PET) revealed increased FDG uptake at this level, confirmed by labelled white blood cells, all favouring graft infection...

BACKGROUND: Bronchial necrosis is a rare but fatal complication after radiation therapy. Because of the anatomical complexity and rarity of this condition, determining the most appropriate management for individual patients is extremely challenging. Lung autotransplantation is a surgical technique that has been applied to hilar neoplastic lesions to preserve pulmonary function and avoid pneumonectomy. We herein report a case of bronchial necrosis secondary to radiotherapy that was treated with lung autotransplantation...

We report a rare case of cystic lymphangioma of the greater omentum, which was treated by laparoscopic resection. A 61-year-old man was referred to our hospital for the treatment of a perigastric cystic lesion. Esophagogastroduodenoscopy revealed neither a mucosal lesion nor a submucosal tumor in the stomach. Abdominal contrast-enhanced computed tomography imaging showed a cystic lesion in the ventral side of the lower part of the stomach and no mass lesions in the liver. The patient underwent laparoscopic resection of the cystic lesion...

BACKGROUND: Wrapping pancreatojejunal anastomosis with omentum to prevent postoperative pancreatic fistula (POPF) has only been reported in non-randomized, controlled trials. Therefore, this study aimed to conduct a randomized, controlled trial to compare outcomes between omental roll-up and non-omental roll-up in pancreatojejunal anastomosis. METHODS: This single-center, randomized, two-arm trail (Clinical Trials Register: NCT03083938) was conducted between February 2017 and February 2019...
