Diagnosis and management of type II endoscopic retrograde cholangiopancreatography-related perforations: a multicenter retrospective study

BackgroundThe management of type II endoscopic retrograde cholangiopancreatography (ERCP)-related perforation is still controversial. This study aimed to compare the effects of covered self-expandable metallic stent (SEMS), surgery, and conservative treatment for type II perforation.MethodsFrom January 2010 to December 2021, this study collected relevant data from five large hospitals in China. The data of ERCP difficulty grading and ERCP-related perforation in 26,673 cases that underwent ERCP during 11 years were retrospectively analyzed. Of 55 patients with type II perforation, 41 patients were implanted with a biliary covered SEMS (stent group), 10 underwent surgery (surgery group), and 4 received conservative treatment (conservative group).ResultsAmong the 55 patients with type II perforation, ERCP and computed tomography diagnostic rates of type II perforation were 10.91% (6/55) and 89.09% (49/55), respectively. The incidence of type II perforation in grade 5 ERCP (0.43%, 11/2,537) was significantly higher than that in grade 1–3 ERCP (0.16%, 32/19,471). (P = 0.004) and grade 1–4 ERCP (0.26%,12/4,665) (P = 0.008), respectively. Among the 10 patients in the surgical group, primary repair was performed in only 7 patients in whom location of the perforation could be identified. The incidence of retroperitoneal abscess was significantly lower in the stent group than in the surgery group (P = 0.018) and the conservative group (P = 0.001), respectively. The average hospital stay in the stent group was shorter than that in the surgery group (P = 0.000) and conservative group (P = 0.001), respectively.ConclusionsThe incidence of type II perforation was dependent on the degree of difficulty of ERCP. The treatment of type II perforation with a covered SEMS can significantly reduce the incidence of retroperitoneal abscess and shorten the hospital stay, with better results than surgical and conservative treatments.

Efficacy and Safety of Endoscopic Through-the-Scope Suture System for Gastrointestinal Defects: A Systematic Review and Meta-analysis.

Recently, a through-the-scope suturing (TTSS) system has received FDA approval and has been evaluated for closing mucosal defects postintervention. We hereby performed a systematic review and pooled meta-analysis of available studies to assess the safety and efficacy of this intervention. We queried the following databases through April 26, 2023: Embase, MEDLINE, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection. Endoscopists utilizing TTSS for the following reasons were included: endoscopic mucosal resection, endoscopic submucosal dissection, peroral endoscopic myotomy, perforation, fistula closure, and/or stent fixation. The outcomes assessed were technical success, primary clinical success (closure of defect without additional intervention), and overall clinical success (closure of defect with/without additional intervention). Random effects model with the DerSimonian Laird approach was used to report event rates expressed as proportions with a 95% CI. A total of 12 studies with 512 patients (mean age of 61.5 ± 18.4y, 54.6% females) were included. The technical success rate was 96.0% (CI: 94.3%-97.7%). The primary clinical success rate was 74.8% (CI: 65.5%-84.1%). The overall clinical success rate was 95.4% (CI: 92.6-98.2%). Only 1 mortality case unrelated to intervention was reported. The TTSS appears safe and effective for closing mucosal defects after therapeutic endoscopic interventions. Further cost-effective studies should be performed comparing with endoclips for use in clinical settings.

Efficacy, Feasibility, and Safety of the X-Tack Endoscopic HeliX Tacking System: A Multicenter Experience.

The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope suturing necessitates removal of the scope, placement of the device, and reinsertion. A single channel, single sequence, through-the-scope suturing device has been developed to improve this process. This study aims to describe the efficacy, feasibility, and safety of a through-the-scope suturing device for gastrointestinal defect closure. This was a retrospective multicenter study involving 9 centers of consecutive adult patients who underwent suturing using the X-Tack Endoscopic HeliX Tacking System (Apollo Endosurgery). The primary outcomes were technical success and long-term clinical success. Secondary outcomes included adverse events, recurrence, and reintervention rates. In all, 56 patients (mean age 53.8, 33 women) were included. Suturing indications included fistula repair (n=22), leak repair (n=7), polypectomy defect closure (n=12), peroral endoscopic myotomy (POEM) site closure (n=7), perforation repair (n=6), and ulcers (n=2). Patients were followed at a mean duration of 74 days. Overall technical and long-term clinical success rates were 92.9% and 75%, respectively. Both technical and clinical success rates were 100% for polypectomies, POEM-site closures, and ulcers. Success rates were lower for the repair of fistulas (95.5% technical, 54.5% clinical), leaks (57.1%, 28.6%), and perforations (100%, 66.7%). No immediate adverse events were noted. This novel, through-the-scope endoscopic suturing system, is a safe and feasible method to repair defects that are ≤3cm. The efficacy of this device may be better suited for superficial defects as opposed to full-thickness defects. Larger defects will need more sutures and probably a double closure technique to provide a reinforcement layer.

EGS P04 Recent ten year experience of Boerhaave’s Syndrome Management in a tertiary Oesophago-gastric Surgery Centre

Abstract Background Oesophageal Perforation (OP) is a low incidence, high complexity gastrointestinal surgical emergency with associated high mortality rates. A consequence of UK centralisation of oesophago-gastric (OG) cancer surgery is passive centralisation of OG surgical emergencies leading to reduced mortality for OP and lower threshold for surgical intervention by high volume OG cancer surgeons. Boerhaave's Syndrome characterised by Mackler’s Triad (vomiting, thoracic pain and subcutaneous emphysema) represents 30% of OP. UCLH has an OG surgery catchment population of 3 million. We present our experience of managing Boerhaave’s syndrome as an OG cancer centre with a dedicated OG Consultant on-call rota. Methods A retrospective review of electronic health records of all adult patients with a radiological diagnosis of OP over a 10 year period from 01/01/2013 to 31/12/2022) at our institution was performed. The inclusion criteria were adult patients with a clinical and radiological diagnosis of Boerhaave’s syndrome. Those with OP due to malignancy, endoscopic, or foreign body perforation were excluded from further analysis. The primary outcome measure was 90-day mortality and the secondary outcome measures were length of stay and reintervention rate. Results 41 patients with Boerhaave’s syndrome were identified (31 male, 10 female) with median age of 62 (46 - 71). 17 (41.5%) patients presented directly to our institution and 24 (58.5%) were transferred from other hospitals. Primary intervention was surgical in 31 (75.6%), endoscopic in 3 (7.3%) and conservative in 7 (17.1%) patients respectively. Overall 90-day mortality was 12.2% but 6.5% in the surgically managed group. Median length of stay was 58 days (22 - 70). 9 patients had reintervention – 7 (17.1%) had a thoracotomy/thoracoscopic surgery for intrathoracic collections and 2 patients (9.8%) had endoscopic intervention. Conclusions This is a report of the experience of managing Boerhaave’s syndrome in a high volume tertiary OG centre. A favourable 90-day mortality rate of 12.2% compares to 38.8% described in a previous UK cohort is likely a result of management in a tertiary centre with appropriate multidisciplinary infrastructure to manage complex patients and provide a consistently high level of perioperative care. The lower mortality rate (6.5%) in the operatively managed group is likely due to patient selection and surgical techniques honed from familiarity with complex cancer and benign oesophageal surgery and working as part of an effective multidisciplinary team.

Endoscopic retrograde cholangiopancreatography-related early perforations: A study of effects of procedure duration, complexity, and endoscopist experience

Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has been transformed from an innovative technique, into a viable alternative to enteral stenting and surgical gastrointestinal anastomosis for patients with gastric outlet obstruction. Even EUS-GE guided ERCP and EUS-guided gastrointestinal anastomosis for the treatment of afferent loop syndrome have been performed, giving patients more less invasive options. However, EUS-GE is still a technically challenging procedure. In order to improve EUS-GE, several techniques have been reported to improve the technical details. With EUS-GE widely performed, more data about EUS-GE’s clinical outcomes have been reported. The aim of the current review is to describe technical details updates, clinical outcomes, and adverse events of EUS-GE.

Endoscopic iatrogenic esophageal perforation and management: a retrospective outcome analysis in the modern era

IntroductionIatrogenic esophageal perforation (IEP) is a severe adverse event (AE) of upper endoscopy procedures (UEPs) associated with morbidity. Management has shifted from surgery to endotherapy with clip closure (CC), self-expanding metal stent (SEMS), and vacuum therapy (VT). Limited analyses measure outcomes during contemporary interventional endoscopy periods.MethodsIEPs associated with EGD, upper EUS, small bowel enteroscopy (SBE), and ERCP at a 3-hospital academic center from January 2011 to December 2023 were identified retrospectively from a centralized AE database. Additional information was obtained from medical records. Statistical analysis was performed using Microsoft Excel and STATA.ResultsThirty-two IEPs from 26 EGDs, 4 EUS, 1 SBE, and 1 ERCP were identified. IEPs occurred mostly after dilation (bougie N = 7; balloon, N = 5) or foreign body removal (N = 6). Most IEPs occurred in the lower esophagus (N = 10) or gastroesophageal junction (N = 8). Diagnosis was made at a median 2 h after the injury by endoscopy (N = 14), CT scan (N = 12), esophagram (N = 5), or x-ray (N = 1). Initial treatment included conservative therapy alone (N = 7), CC (N = 3), SEMS (N = 14), SEMS plus CC (N = 3), or surgery (N = 3). Eleven patients required additional treatment including repeat SEMS or adjustment (N = 4) or VT (N = 1). No surgical interventions were required after 2013. The median hospital stay was 3 days. Disposition included discharge to home (N = 25), long-term care facility (N = 2), 4 deaths (12.5% of IEPs), and 1 unknown.ConclusionsIEPs are rare and occur throughout the esophagus after any UEP. The majority are recognized immediately and managed with endotherapy, or rarely, surgery today. These characteristics likely explain the low mortality in this study.

Combined endoscopic sinus surgery and endonasal septal perforation repair: Symptom outcomes and perforation closure rates.

Combined endoscopic sinus surgery and nasal septal perforation repair is technically feasible. NOSE-Perf is a recently developed patient-reported outcome measure for nasal septal perforation. The decision to perform combined ESS and NSP repair should be made on a case-by-case basis.

Causes and Management of Endoscopic Retrograde Cholangiopancreatography-Related Perforation: A Retrospective Study.

Endoscopic retrograde cholangiopancreatography (ERCP) is essential for diagnosing and treating biliopancreatic disease. Because ERCP-related perforation can result in death, therapeutic decisions are important. The aim of this study was to determine the cause of ERCP-related perforation and suggest appropriate management. Between January 1999 and August 2022, 7,896 ERCPs were performed in our hospital. We experienced 15 cases (0.18%) of ERCP-related perforation and conducted a retrospective review. Of the 15 patients, 6 were female and 9 were male, and the mean age was 77.1 years. According to Stapfer's classification, the 15 cases of ERCP-related perforation comprised 3 type I (duodenum), 3 type II (periampullary), 9 type III (distal bile duct or pancreatic duct), and no type IV cases. Fourteen of 15 (92.6%) were diagnosed during ERCP. The main cause of perforation was scope-induced damage, endoscopic sphincterotomy, and instrumentation penetration in type I, II, and III cases, respectively. Four patients with severe abdominal pain and extraluminal fluid collection underwent emergency surgery for repair and drainage. One type III patient with distal bile duct cancer underwent pancreaticoduodenectomy on day 6. Three type III patients with only retroperitoneal gas on computed tomography (CT) performed immediately after ERCP had no symptoms and needed no additional treatment. Seven of the 15 patents were treated by endoscopic nasobiliary drainage (n=5) or CT-guided drainage (n=2). There were no deaths, and all patients were discharged after treatment. Early diagnosis and appropriate treatment are important in managing ERCP-related perforation.

Efficacy of the endoscopic clip method in patients treated with the endoscopic clip method forgastrointestinal bleeding, perforations and fistulas.

Introduction:Gastrointestinal bleeding, perforations and fistulas are common conditions and can betreated with endoscopic procedures that are considered as minimally invasive procedures. With theintroduction of ovarian thescope clips (OTSC), the success of the procedure is increasing and its use isrecommended as the first step in treatment modalities. This study aims to contribute to the literatüre and share our experiences.
 Methods:Between 2020 and 2023, 21 patients who underwent endoscopic clipapplication after gastrointestinal tract perforations, anastomotic leaks, fistulas, bleeding andendomucosal resection in our clinic were evaluated.
 Results:A total of 21 patients, 13 males (61.9%), were included in our study. There were 16 patientsin the bleeding group, one in the anatomical leak group, one in the fistula group and three in theendomucosal resection group. No failure was seen in any patient in the bleeding group.Antithrombotic drug use did not change the success. No surgical procedure was required. At 30-dayfollow-up, only one patient (6.25%) had rebleeding and required reoperation. No complications weredetected in the procedures of endomucosal resection, fistula and clips applied in anastomotic leakage.There was a positive correlation between erythrocyte suspension replacement and length ofhospitalization (p

Endoscopic retrograde cholangiopancreatography (ERCP)-related duodenal perforations are a worrisome and life-threatening complication.

Painless Endoscopic Repair of Duodenal Ulcer Perforation: A Case Report

This paper reports a case of duodenal ulcer (A1 stage) after general gastroscopy, when the patient left hospital without discomfort, but felt persistent aggravated abdominal pain in about 20 minutes, so admitted to the emergency department due to perforation of duodenal ulcer showed by CT, and aspirated by CO2 air pump under general anesthesia in the operating room four hours later, performed painless endoscopic perforation repair. Then, he released pneumatosis by puncture, and accepted ten days symptomatic treatment such as anti-infection following fasting water and gastric tube insertion, after that recovered and discharged from hospital, avoiding surgery, which supplements endoscopic minimally invasive treatment for perforation of duodenal ulcer in China.

The role of endoscopic perforation of the third ventricular floor in the treatment of pineal neoplasms. One solution for different approaches to the treatment of pineal tumors

Neoplasms of the pineal region include an extensive list of pathological formations, which represent one of the most difficult areas for surgical treatment. The resolution of hydrocephalus in pineal tumors is one of the most important tasks in the treatment of tumors of this localization. In the presented work, we report on an alternative surgical strategy for the management of certain patients with pineal neoplasms, which allows treating the symptomatic manifestation of hydrocephalus by endoscopic third ventriculostomy and further conducting specific therapy or observing pathological formation in the pineal region and the posterior parts of the third ventricle.

Endoscopic aqueductal membrane fenestration was effective for intractable hydrocephalus after removal of a nongerminomatous germ cell tumor exhibiting growing teratoma syndrome: a case report

BackgroundPrimary central nervous system (CNS) germ cell tumors (GCTs) are rare neoplasms predominantly observed in the pediatric and young adult populations. A mixed GCT including immature teratoma exhibiting growing teratoma syndrome is presented. The pathogenesis of growing teratoma syndrome remains unclear, and its treatment strategy has not been established. GCTs are often located within the ventricles, causing hydrocephalus, which sometimes improves after removal of the tumor due to restoration of cerebrospinal fluid (CSF) flow. On the other hand, even if the flow route of CSF from the third ventricle to arachnoid granulations on the brain surface quadrigeminal cistern is restored after removal of the tumor, hydrocephalus may not improve.Case presentationA case whose intractable hydrocephalus improved after penetrating the aqueductal membrane via endoscopy is described. An 11-year-old boy was treated for pineal intracranial growing teratoma syndrome (IGTS). The tumor grew rapidly in a short period, and hydrocephalus progressed despite endoscopic third ventriculostomy (ETV). Although the obstruction was removed by radiation, chemotherapy, and total tumor resection, the hydrocephalus did not improve. Endoscopic membrane perforation was performed because a membrane-like structure was seen at the entrance of the cerebral aqueduct on magnetic resonance imaging. The hydrocephalus improved immediately after the operation, and the patient’s consciousness disturbance also improved significantly.ConclusionThe purpose of this report is to update the current knowledge and standards of management for patients with growing teratoma syndrome, as well as to drive future translational and clinical studies by recognizing the unmet needs concerning hydrocephalus.

Quality improvement project on the development of a management algorithm for iatrogenic perforations and the long-term impact on physician knowledge.

Background and study aims Acute iatrogenic endoscopic perforations (AIEPs) can have high morbidity and mortality, especially colonic perforations. Knowledge of diagnosis and AIEP management can improve patient care. The aims of this study were to: develop an evidence-based AIEP management algorithm; study its short-term and long-term impact on physician knowledge; and evaluate physician knowledge using hypothetical clinical scenarios. Methods An institutional AIEP management algorithm was created using the most current recommendations from the American Society for Gastrointestinal Endoscopy and the European Society of Gastrointestinal Endoscopy. Input from advanced endoscopists, nurses, and anesthesiologists was also obtained. We assessed change in physician knowledge using a 10-item questionnaire before (pretest), a standardized one-page AIEP educational material and algorithm immediately after (post-test) to test short-term retention, and 6 months later (6-month reassessment) to test long-term retention. With the 6-month reassessment, two clinical scenarios based on real AIEP were presented to evaluate application of knowledge. Results Twenty-eight subjects (8 gastroenterology fellows and 20 practicing gastroenterologists) participated in the assessments. Pretest and immediate post-test accuracies were 75 % and 95 % ( P < 0.01), respectively. Six-month reassessment accuracies were 83.6 %, significantly worse compared to post-test accuracies ( P < 0.05), but significantly improved compared to pretest accuracies ( P < 0.05). Accuracies for clinical scenarios #1 and #2 were 67.5 % and 60.3 %, respectively. Fellows had similar accuracies when compared to practicing gastroenterologists. Conclusions Using standardized methodology and a multidisciplinary approach, an AIEP management algorithm was created to improve patient care and alleviate physician and staff stress. In addition, we showed that a one-page educational document on perforations can significantly improve short-term and long-term physician knowledge, although periodic reeducation is needed.

Fully covered self-expandable metal stent for intraprocedural or late-diagnosed Type-II endoscopic retrograde cholangiopancreatography-related perforations

BackgroundPerforations related to endoscopic retrograde cholangiopancreatography (ERCP) are rare but life-threatening complications. The treatment of Type-II-periampullary perforations that develop during endoscopic sphincterotomy remains a topic of discussion. This study aimed to evaluate the usefulness of fully covered self-expanding metal stenting (FCSEMS) for treating Type-II perforations.MethodsThe files of all patients who underwent the ERCP procedures between January 2015 and October 2021 were retrospectively reviewed; patients with Stapher Type-II perforation were included in the current study. Patients with FCSEMS were classified into two groups: those who underwent FCSEMS and those who were conventionally followed up. Moreover, patients with FCSEMS were classified into two subgroups: those who underwent simultaneous stenting and those who underwent late stenting. Mortality, surgical intervention, percutaneous drainage, length of hospital stay, and inflammatory markers were all compared between the groups.ResultsOf the 9253 patients undergoing ERCP during the study period, 28 patients (0.3%) were found to have Type-II perforation. The mean age of these patients was 67.7 ± 3.9 years, and 15 patients were female. FCSEMS was performed on 19 patients, whereas 9 patients were on conventional follow-up. None of the patients developed mortality. In the conventional follow-up group, one patient required percutaneous drainage and one required surgical intervention. In contrast, none of the patients in the FCSEMS group required additional intervention. At a statistically significant level, the length of hospital stay was found to be shorter in the FCSEMS group. There was no difference in inflammatory markers between the two groups. In nine patients, FCSEMS was performed simultaneously, whereas, in ten patients, FCSEMS was performed later because they required a second intervention. These two subgroups did not differ in terms of outcomes.ConclusionsFCSEMS is a safe and effective treatment modality for patients with Type-II perforation. Moreover, it can be safely used in patients whose perforations are diagnosed during the ERCP procedure and in patients whose diagnoses are made after the procedure.

TU1.12 Video Presentation: The OVESCO Clip for Endoscopic Treatment of Gastrocutanoeus Fistula

Abstract Background Percutaneous endoscopic gastrostomy (PEG) is an important route of nutrition in many patients. PEG removal usually leads to spontaneous closure in a few days. Gastrocutaneous fistula (GCF) after PEG removal is an uncommon complication occurring in 2% of patients. Despite its rarity, it is responsible for significant morbidity and reduced quality of life. Treatment is initially focused on medical management and endoscopic clipping, with advanced endoscopic techniques and surgery reserved for selected cases. Method We present a video presentation demonstrating successful endoscopic treatment of GCF using the OVESCO Over the Scope clip with resolution of symptoms and closure of the fistula tract. The device is a novel innovation designed to achieve tissue apposition and compression without ischaemia. It is licensed for Gastrointestinal iatrogenic defects, endoscopic perforation, bleeding and GCF. The 72 year old patient had debilitating symptoms of gastric leakage for over a year despite previous attempts at endoscopic clipping, fibrin glue and curettage of the fistula tract. Results As shown in the video, the clip achieved good opposition with no post procedural leak. The patient was reviewed at 3 and 12 months with no recurrence of their symptoms. The external cutaneous opening had closed at 3 months. The patient reported an increase in weight, improved mood and a greater quality of life following the intervention. Conclusion The OVESCO clip has been proven to facilitate successful endoscopic closure of GCF in selected patients in whom initial treatment measures have failed. This mitigates the need and risks of surgical closure.

Advanced endoscopic resection for colorectal dysplasia in inflammatory bowel disease: a meta-analysis.

Background and study aims Little is known about outcomes of advanced endoscopic resection (ER) for patients with inflammatory bowel disease (IBD) with dysplasia. The aim of our meta-analysis was to estimate the safety and efficacy of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for dysplastic lesions in patients with IBD. Methods We performed a systematic review through Jan 2021 to identify studies of IBD with dysplasia that was treated by EMR or ESD. We estimated the pooled rates of complete ER, adverse events, post-ER surgery, and recurrence. Proportions were pooled by random effect models. Results Eleven studies including 506 patients and 610 lesions were included. Mean lesion size was 23 mm. The pooled rate of complete ER was 97.9 % (95 % confidence interval [CI]: 95.3 % to 99.7 %). The pooled rate of endoscopic perforation was 0.8 % (95 % CI:0.1 % to 2.2 %) while bleeding occurred in 1.6 % of patients (95 %CI:0.4 % to 3.3 %). Overall, 6.6 % of patients (95 %CI:3.6 % to 10.2 %) underwent surgery after an ER. Among 471 patients who underwent surveillance, local recurrence occurred in 4.9 % patients (95 % CI:1.0 % to 10.7 %) and metachronous lesions occurred in 7.4 % patients (95 %CI:1.5 % to 16 %) over a median follow-up of 33 months. Metachronous colorectal cancer (CRC) was detected in 0.2 % of patients (95 %CI:0 % to 2.2 %) during the surveillance period. Conclusions Advanced ER is safe and effective in the management of large dysplastic lesions in IBD and warrants consideration as first-line therapy. Although the risk of developing CRC after ER is low, meticulous endoscopic surveillance is crucial to monitor for local or metachronous recurrence of dysplasia.

Peri and Postoperative Compli-cations of Endoscopic Posterior Limited Septoplasty Versus Con-ventional Method Septoplasty in Endoscopic Nasal Surgery

Background: A significant percentage of patients undergone endoscop-ic sinus surgery has septal deviation, that disturb adequate access to the osteomeatal complex or to the region of axilla of the middle turbinate. The good exposure is the most important key to a successful surgery. Straightening such a deflection improve the access to the work site on the lateral wall of the nasal cavity. Objective: To compare the peri and post operative complications be-tween conventional septoplasty (cottle's method) and the endoscopic posterior limited septoplasty in endoscopic sinus surgery. Patients and Methods: Forty patients (all of them had a limited posterior nasal septal deviation ,nasal and paranasal sinus pathology in addition to septal deformity),were selected and divided randomly into two equal groups, (by the type of surgery for septal correction. group A which underwent conventional (Cottle's septoplasty), while group B that had endoscopic type septoplasty). All patients were assessed in the otolaryn-gology department in AL- Immamain Al khadimain medical city, from October 2016 to November 2017.patients were evaluated pre and post operatively by clinical and endoscopical examination, and followed in a period of 1week, 1month and 3months post operatively. Results: Functional endoscopic sinus surgery was the most primary sur-gery done, followed by Dacrocystorhinostomy and Endoscopic spheno-palatine artery ligation .Most common intraoperative complication was mucosal flap tear which observed more in conventional group, .Regarding mean operative time for limited septoplasty it was shorter in endoscopic group .Synechia and delay wound healing as a post opera-tive complication was more in endoscopic group, while hematoma and perforation was more in conventional group. Conclusion: During endoscopic sinus surgery, limited posterior septal deviation can be corrected by endoscopic method which provides better direct visualization of the deviation, more conservative surgical manipu-lation, shorter in time and less intra and post-operative complications.
