Frequency Of Anastomotic Leakage Research Articles

Comparative analysis of safety and effectiveness between natural orifice specimen extraction and conventional transabdominal specimen extraction in robot-assisted colorectal cancer resection through systematic review and meta-analysis.

The goal of this systematic review and meta-analysis is to evaluate the perioperative and oncologic results of natural orifice specimen extraction (NOSE) compared to conventional transabdominal specimen extraction (TASE) in robotic-assisted surgery for colorectal cancer. A comprehensive electronic search will be performed on PubMed, Embase, and the Cochrane Library to find research articles published from the beginning of the databases to July 2024 that focus on patients who have undergone robotic-assisted surgery for colorectal cancer. Specifically, this review will compare NOSE with conventional TASE. Only studies published in English will be considered. Literature screening will adhere closely to predetermined criteria for inclusion and exclusion, specifically targeting randomized controlled trials and cohort studies. The evaluation of quality will involve the use of the Newcastle-Ottawa Scale (NOS). Meta-analysis of the included studies' data will be performed using Review Manager 5.4.1. In the final analysis, 9 retrospective cohort studies comprising 1571 patients were included. Out of these, 732 patients opted for NOSE, while 839 patients chose conventional TASE in robotic colorectal surgery. Patients who received TASE experienced enhancements in hospital stay duration, time until first gas passage, wound infection rates, and time until the first intake of a liquid diet. Nevertheless, there were no notable distinctions noted between the two methods regarding surgery duration, projected blood loss, intestinal blockage, or frequency of anastomotic leakage. In patients undergoing robotic-assisted colorectal surgery, the safety and feasibility of NOSE are demonstrated. Compared to traditional TASE, it provides clear benefits including shorter hospital stays, earlier first flatus, quicker initiation of a liquid diet, and lower risk of wound infection.

Implementation of perioperative FLOT compared to ECX/EOX chemotherapy regimens in resectable esophagogastric adenocarcinomas: an analysis of real-world data.

Perioperative 5-FU, leucovorin, oxaliplatin, and docetaxel (FLOT) is recommended in resectable esophagogastric adenocarcinoma based on randomised trials. However, the effectiveness of FLOT in routine clinical practice remains unknown as randomised trials are subject to selection bias limiting their generalisability. The aim of this study was to evaluate the implementation of FLOT in real-world patients. Retrospectively collected data were analysed in consecutive patients treated before or after the implementation of FLOT. The primary endpoint was complete pathological response (pCR) and secondary endpoints were margin-free resection (R0), overall survival (OS), relapse-free survival (RFS) tolerability of chemotherapy and surgical complications. Mean follow-up time for patients treated with FLOT (n = 205) was 37.7 versus 47.0 months for epirubicin, cis- or oxaliplatin, and capecitabine (ECX/EOX, n = 186). Surgical resection was performed in 88.0% versus 92.0%; pCR were observed in 3.8% versus 2.4%; and R0 resections were achieved in 78.0% versus 86.0% (p = 0.03) in the ECX/EOX and FLOT cohorts, respectively. Survival analysis indicated no significant difference in RFS (p = 0.17) or OS (p = 0.37) between the cohorts with a trend towards increased OS in performance status 0 (hazard ratio [HR] = 0.73, 95% confidence interval [CI]: 0.50-1.04). More patients treated with ECX/EOX completed chemotherapy (39% vs. 28%, p = 0.02). Febrile neutropenia was more common in the FLOT cohort (3.8% vs. 11%, p = 0.0086). 90-days mortality (1.2% vs. 0%) and frequency of anastomotic leakage (8% vs. 6%) were equal and low. Patients receiving FLOT did not demonstrate improved pCR, RFS or OS. However, R0 rate was improved and patients in good PS trended towards improved OS.

Modified Collard technique is more effective than circular stapled for cervical esophagogastric anastomosis in prevention of anastomotic stricture: a propensity score-matched study.

The anastomotic technique after esophagectomy is of great interest in the prevention of anastomotic complications that adversely affect postoperative recovery. This study aimed to compare the clinical outcomes of modified Collard (MC) and circular stapled (CS) anastomoses after esophagectomy. A total of 504 consecutive patients with thoracic esophageal cancer who underwent esophagectomy and cervical esophagogastric CS or MC anastomosis from January 2013 to December 2019 were enrolled. Out of 504 patients, 134 and 370 underwent CS and MC anastomoses. The frequency of anastomotic leakage and stricture was significantly lesser in the MC group than in the CS group (3.0 vs. 10.5%, P = 0.0014 and 11.1 vs. 34.3%, P < 0.001, respectively). CS anastomosis was an independent risk factor for anastomotic stricture (odds ratio, 4.89; P < 0.001). Oral intake was significantly higher in the group without anastomotic stricture than in the group with anastomotic stricture at 2, 3, and 6months postoperatively (P <0.001, P = 0.013, and P <0.001, respectively). The percentage body weight loss (%BWL) was -12.2% in the group with anastomotic stricture and -7.5% in the group without anastomotic stricture at 3months postoperatively (P = 0.0012). Anastomotic stricture was an independent factor associated with %BWL (odds ratio, 4.86; P = 0.010). Propensity score-matched analysis, which included 88 pairs of patients, confirmed a significantly lower anastomotic stricture rate in the MC group than in the CS group (10.2 vs. 35.2%, P < 0.001). MC anastomosis is better than CS anastomosis for reducing the frequency of anastomotic stricture, which may be useful for maintaining early postoperative nutritional status.

Complications of Colostomy Reversal in Patients with Imperforate ANUS

Background: Colostomy reversal after definitive procedure in patients of Imperforate Anus (for example; PSARP) can be difficult and challenging for surgeon due to proximal and distal gut lumen discrepancy, short length of distal loop, difficult mobilization of stoma. These factors affect the anastomosis and anastomosis is done under tension due to these factors. Colostomies which are reversed under tension mostly results in anastomosis leakage and increases the morbidity and mortality rate. The objective of this study to assess postoperative outcome in terms of complications following colostomy closure in patients with imperforate anus. Material and Methods: This is a prospective study done at the Department of Pediatric Surgery, National Institute of Child Health Karachi during the period of 6months from December 2016 to June 2017. A Self- structured performa was used to collect the data of total 84 Patients who Underwent Colostomy Reversal after definitive procedure for imperforate anus . Data analyzed through SPSS version 20. A descriptive statistical analysis of continous and categorical variables were performed. Continuous data (like age) expressed as mean SD. The categorical data like gender, wound infections , anastomosis leakage expressed in frequency and percentages. Results: Out of total 84 children, majority 51 (60.7%) children were presented with ≤4 years of age (Mean age 4.15±3.12 years). Majority 55 (65.5%) children were presented with &gt;8 kg of weight (Mean weight 13.31±6.00 kg). There were 41 (48.8%) males and 43 (51.2%) females. Intra-operative difficulty was found in 55 (65.5%) children. Postoperative complication showed that wound infections were observed in 10 (11.9%) children while frequency of anastomotic leakage was found in 12 (14.3%) children. Conclusion: Anastomotic leakage was found to be higher following colostomy closure in children with intra-operative difficulty due to proximal and distal gut lumen discrepancy, short length of distal loop and dense adhesions making difficult the mobilization of stoma.

Anastomosis oversewing technique to prevent leakage after oesophagectomy: a propensity score-matched analysis.

Oesophagogastric anastomosis is a core part of oesophagectomy, and anastomotic leakage is among its main concerns. We used the oversewing technique to reinforce the anastomosis created with a circular stapler. This study investigated the use of oversewing to reduce the incidence of anastomotic leakage without increasing morbidity. This study enrolled 1734 patients who underwent oesophagectomy for oesophageal cancer between April 2012 and December 2019. Using propensity score-matched analysis, the clinical results of postoperative complications were compared between anastomotic-oversewn and -unsewn oesophagectomies. Of the 1734 patients, 661 were included in the anastomotic-unsewn group and 661 in the anastomotic-oversewn group after propensity score matching. The clinical characteristics did not differ between the 2 groups, but the frequency of anastomotic leakage was significantly higher in the anastomotic-unsewn group than in the anastomotic-oversewn group (10.3% vs 4.7%, P < 0.001). Multivariable logistic analysis showed oversewn anastomosis and smoking history as the independent factors associated with anastomotic leakage (odds ratios, 0.399 and 2.383; P < 0.001 and P = 0.012, respectively). On the sub-group analysis, the relative risk for anastomotic leakage was significantly higher with unsewn than with oversewn anastomosis in patients <65 years old, those with American Association of Anesthesiologists score II, those who had middle segment oesophageal cancer and those who have undergone the McKeown approach and cervical anastomosis. Anastomosis oversewing technique may be a practical method to reduce anastomotic leakage, especially in younger patients and those who have undergone the McKeown approach and cervical anastomosis.

RA04.02: THE COMPLICATIONS AND LONG-TERM SURVIVAL IN TRANS-MEDIASTINAL RADICAL ESOPHAGECTOMY

Abstract Background (Bachground) The radical esophagectomy for esophageal cancer is an invasive therapy for a long one-lung ventilation. We have been stylized trans-mediastinal radical esophagectomy in order to relieve the pulmonary complications. Methods (Candidates) The radical esophagectomy (R0/1, gastric tube reconstruction) by thoracotomy/thoracoscopy (groupT) or mediastinoscopy (groupM) were performed for 120/58 or 131 esophageal cancer patients. The long-term therapeutic results of trans-mediastinal radical esophagectomy and complications (Clavien-Dindo classification≧ 2) are investigated. Results (Results) In clinicopathological features, neoadjuvant therapy, cStage III/IV advanced cases, or R1 resection was significant in groupT (P &lt; 0.01). The frequency of anastomotic leakage and recurrent nerve paralysis were not different in both group (P = 0.94, 0.69, respectively), whereas pulmonary complication was significantly decreased (25.2 vs 10.9%, P = 0.003). Any complications were slightly frequent in groupT than in group M (32.4 vs 29.5%, P = 0.59). The 5-years overall survival was slightly better in group M than in group T due to the effects of disease stage (53.5% vs 63.4%, P = 0.19). In the subgroup analysis, the overall survival rate was similar in each clinical stage. Conclusion (Discussion) The trans-mediastinal radical esophagectomy was effective for the relief of pulmonary complication, and was not inferior to the esophagectomy by thoracotomy or thoracoscopy in the prognosis.

Mid-term absorbable monofilament is safe and effective for gastrointestinal anastomosis - PROMEGAT - A single-arm prospective observational study.

IntroductionVarious suture materials and suture techniques are used to perform gastrointestinal anastomosis after tumour resection, but the best combination is still a matter of debate.MethodsThis multi-centre, international, single-arm, prospective observational study aimed at demonstrating the non-inferiority of a mid-term absorbable monofilament in comparison to braided sutures in gastrointestinal anastomosis. Monosyn suture was used to create the gastrointestinal anastomosis and the frequency of anastomotic leakage until day of discharge was chosen as the primary parameter. The outcome was compared to the results published for braided sutures in the literature. Secondary parameters were the time to perform the anastomosis, length of hospital stay, costs, and postoperative complications.ResultsThe anastomosis leakage rate was 2.91%, indicating that Monosyn suture was not inferior to braided sutures used in gastrointestinal anastomosis. Of the reported anastomotic suture techniques, the single layer continuous method was the fastest and most economical technique in the present observational study.ConclusionMonosyn suture is safe and effective in gastrointestinal anastomosis and represents a good alternative to other sutures used for gastrointestinal anastomosis. With regard to safety, time and cost-efficiency, the single-layer continuous technique should be considered a preferred method. The transfer of results from clinical studies into daily practice with regard to surgical techniques for gastrointestinal anastomosis should be further evaluated in larger studies or in nationwide registries.

Anastomotic Leakage Using Linear Stapling Device with Pre-attached Bioabsorbable Polyglycolic Acid Felt After Laparoscopic Anterior Resection.

Many studies have evaluated the risk factors for anastomotic leakage after laparoscopic anterior resection. In this study in order to increase the tightness of anastomoses and prevent bleeding from their staple lines, a linear stapler with pre-attached bioabsorbable polyglycolic acid (PGA) felt was used for rectal transection, and the short-term surgical outcomes were evaluated. A prospective registry of 62 patients with rectosigmoidal or rectal carcinoma who initially underwent laparoscopic anterior resection using PGA felt for rectal transection was reviewed. The overall frequency of anastomotic leakage was 1.6% (1/62), and none of the patients developed postoperative staple line bleeding or other adverse events related to the use of PGA felt. The frequency of anastomotic leakage was relatively low, and therefore the use of a linear stapler with pre-attached bioabsorbable PGA felt might reduce the risk of adverse events related to anastomosis, especially anastomotic leakage.

THE TRANSANAL REINFORCEMENT OF LOW COLORECTAL ANASTOMOSIS: FIRST EXPERIENCE AND PERSPECTIVES

AIM. It was to evaluation the effect of using of transanal reinforcement of low colorectal anastomosis to the frequency of anastomotic leakage. MATERIALS AND METHODS. The study included six patients who underwent a low anterior resection for rectal cancer and the transanal reinforcement anastomosis. Preventive stomas not formed. RESULTS. The study contains an analysis of the immediate results of patients treatment. The leakage of the anastomosis was developed in 3 of 6 patents. This required break down of the anastomosis in one and the formation of diverting stoma in two patients. CONCLUSION. The first experience of the transanal reinforcement for low colorectal anastomosis is unsuccessful because of leakage appeared in every second patient. More careful selection of patients for this method is required.

Anastomotic complications after robot-assisted laparoscopic and open radical prostatectomy

Objective Anastomotic complications are well known after radical prostatectomy (RP). The vesicourethral anastomotic technique is handled differently between open and robotic RP. The aim of the study was to investigate whether the frequency of anastomotic leakages and strictures differed between patients undergoing retropubic radical prostatectomy (RRP) and robot-assisted radical prostatectomy (RARP) and to identify risk factors associated with these complications. Materials and methods The study included 735 consecutive patients who underwent RRP (n = 499) or RARP (236) at the Department of Urology, Rigshospitalet, Denmark, in a complete 3 year period from 2010 to 2012. Univariate and multivariate logistic regression analysis was used to analyse associations between surgical procedure (RRP vs RARP) and anastomotic complications. Analyses included age, smoking status, diabetes, hypertension, surgeon, prostate volume and anastomotic leakage as variables. Owing to a low number of events, multivariable analyses only included smoking status, diabetes and prostate volume for anastomotic leakage, and age, smoking status, prostate volume and anastomotic leakage for anastomotic strictures. Results The frequency of anastomotic leakage was 2.9%. Anastomotic stricture was seen in 4.9% of patients during follow-up. No differences were found in the frequency of anastomotic leakage (p = 0.35) or strictures (p = 0.35) between RRP and RARP. Univariate analysis demonstrated an association between surgeon and the risk of anastomotic strictures in RRP patients (p = 0.02). No other independent risk factors were identified. Conclusion Overall, the anastomotic complication rate in this cohort is similar to other published reports. No obvious risk factors for anastomotic complications could be identified, which in part was due to the low number of events.

Intrathoracic anastomotic leakage after gastroesophageal cancer resection is associated with increased risk of recurrence

ObjectiveIntrathoracic anastomotic leakage after intended curative resection for cancer in the esophagus or gastroesophageal junction has a negative impact on long-term survival. The aim of this study was to investigate whether an anastomotic leakage was associated with an increased recurrence rate. MethodsThis nationwide study included consecutively collected data on patients undergoing curative surgical resection with intrathoracic anastomosis, alive 8 weeks postoperatively, between 2003 and 2011. Patients with incomplete resection, or metastatic disease intraoperatively, were excluded. Only biopsy-proven recurrences were accepted. ResultsIn total, 1085 patients were included. The frequency of anastomotic leakage was 8.6%. The median follow-up time was 29 months (interquartile range [IQR]: 13-58 months). Overall, 369 (34%) patients had disease recurrence, of which 346 patients died of recurrent gastroesophageal carcinoma. Twenty-three patients were alive with recurrence at the censoring date. In the study period, 333 patients died without signs of recurrent disease.The overall median time to recurrence was 66 weeks (IQR: 38-109 weeks). Distant metastases were found in 267 (25%), and local disease recurrence in 102 (9%) patients. Overall, 5-year disease-free survival in patients with leakage was 27%, versus 39% in those without leakage (P = .017). Anastomotic leakage was independently associated with higher risk of recurrence (hazard ratio [HR] = 1.63; 95% confidence interval [CI]: 1.17-2.29, P = .004) and all-cause mortality (HR = 1.57; 95% CI: 1.23-2.05, P < .0001). ConclusionsIntrathoracic anastomotic leakage increased the risk of recurrence in patients who underwent curative gastroesophageal cancer resection.

Does the Single-Stapling Technique for Circular-Stapled Esophagojejunostomy Reduce Anastomotic Complications After Laparoscopic Total Gastrectomy?

Laparoscopic total gastrectomy (LTG) is used for early gastric cancer (EGC) in the upper stomach. However, the incidences of postoperative anastomotic complications such as leakage and stricture remain high. This study investigated whether using a single-stapling technique (SST) instead of a hemi-double-stapling technique (HDST) for intracorporeal circular-stapled esophagojejunostomy could reduce anastomotic complications after LTG. This retrospective study included 136 patients with EGC treated by LTG with intracorporeal circular-stapled esophagojejunostomy. Originally, HDST was used for esophagojejunostomy in 71 patients (original group). Thereafter, the esophagojejunostomy procedure was modified, and SST was used in a further 65 patients (modified group). The impact of the anastomotic procedure (SST or HDST) on anastomotic complications after LTG was determined by uni- and multivariate analyses. The incidence of anastomotic complications was significantly lower in the modified group (7.7 %) than in the original group (22.5 %; P = 0.017). The frequency of anastomotic leakage was lower in the modified group (3.1 %) than in the original group (9.9 %), although the difference was not statistically significant. Meanwhile, the frequency of anastomotic stricture was significantly less common in the modified group (6.2 %) than in the original group (18.3 %; P = 0.032). Multivariate analysis showed that anastomotic procedure with SST was significantly associated with a lower rate of postoperative anastomotic complications (odds ratio [OR], 0.217; 95 % confidence interval [CI], 0.063-0.631; P = 0.004), as was the operation time (OR, 0.237; 95 % CI 0.082-0.667; P = 0.007). The use of SST for intracorporeal circular-stapled esophagojejunostomy could reduce anastomotic complications after LTG.

Current Outcome of Esophagectomy in the Very Elderly: Experience of a German High-volume Center

Operative management of esophageal carcinoma in the very elderly is still controversially discussed. It is not yet decided whether the risk warrants the procedure. The aim of this study is to analyze the outcome of esophagectomy for esophageal cancer in the very elderly. Factors influencing the clinical course and determining the outcome are identified. A retrospective study 292 consecutive cases of esophagectomy for nonmetastatic esophageal cancer at a German tertiary referral hospital between 2004 and 2011 were reviewed. Two age groups (75 years or older and younger than 75 years) were formed. The mean age was 63 years. Altogether 45 patients were 75 years or older. There were no significant differences in American Society of Anesthesiologists score, operative procedure, or in the frequency of anastomotic leakage between the age groups. However, very elderly patients with anastomotic leak had an eight times higher risk for fatal outcome than the very elderly without leak (odds ratio [OR], 8.54; 95% confidence interval [CI], 1.0 to 112.18; P = 0.025). Moreover, the odds for postoperative death were five times higher in very elderly patients with leak than in younger patients sustaining anastomotic leakage (OR, 5.67; 95% CI, 0.67 to 73.83; P = 0.046). In general, the very elderly had a three times higher risk for a fatal outcome (OR, 3.30; 95% CI, 1.37 to 7.86; P = 0.008). In-hospital mortality of the very elderly was 11 out of 45 compared with 8 per cent (20 of 247) in the younger group. Fatal outcome was more often caused by medical (seven) than by surgical complications (four cases). The remaining 34 patients recovered well. Very elderly patients undergoing esophagectomy have no elevated risk for occurrence of surgical complications, whereas the mortality of these complications is much higher. Improved outcome is achievable by timely management of postoperative surgical as well as medical complications. Notwithstanding the increased mortality, esophagectomy should be considered in thoroughly selected very elderly patients with curable esophageal carcinoma.

Efficacy of the Predicted Operation Time (POT) Strategy for Synchronous Colorectal Liver Metastasis (SCLM): Feasibility Study for Staged Resection in Patients with a Long POT

BackgroundThe optimal surgical strategy for resectable synchronous colorectal liver metastases (SCLM), whether simultaneous or staged resections, still remains obscure. The aim of this study was to assess the efficacy of the predicted operation time (POT) strategy, which recommends staged resections in case of POT ≥6 h, otherwise selecting simultaneous resection. MethodsThis was a prospective, nonrandomized, single-institution study. Fifty-nine patients with SCLM underwent tumor resection according to the POT strategy, with patients with a longer POT (≥6 h) undergoing staged resection. Morbidity, overall hospitalization, tumor resection rates, and survival were compared with that of 86 patients who underwent simultaneous resection for SCLM irrespective of POT from 1992 to 2004. ResultsThe former simultaneous and the latter POT strategy groups were similar in terms of patient and tumor demographics as well as surgical procedures. Of the 59 POT group patients, 26 patients (44 %) experienced 40 postoperative complications. Comparing the surgical results of simultaneous resection from 1992 to 2004 and those of resection according to the POT strategy, morbidity (64 vs. 44 %, p = 0.02), frequency of anastomotic leakage (21 vs. 5 %, p < 0.01), and length of hospital stay (27 vs. 18 days, p < 0.01) were significantly lower in the latter group, while tumor resection rates (85 vs. 87 %, p = 0.77) were not different. ConclusionsThe POT strategy is effective in reducing the morbidity in SCLM patients by selecting staged resections in the high-morbidity-risk group without adverse effects on oncologic outcome.

A prospective, randomised, controlled, double-blind phase I-II clinical trial on the safety of A-Part® Gel as adhesion prophylaxis after major abdominal surgery versus non-treated group

BackgroundPostoperative adhesions occur when fibrous strands of internal scar tissue bind anatomical structures to one another. The most common cause of intra-abdominal adhesions is previous intra-abdominal surgical intervention. Up to 74% of intestinal obstructions are caused by post surgical adhesions. Although a variety of methods and agents have been investigated to prevent post surgical adhesions, the problem of peritoneal adhesions remains largely unsolved. Materials serving as an adhesion barrier are much needed.Methods/DesignThis is a prospective, randomised, controlled, patient blinded and observer blinded, single centre phase I-II trial, which evaluates the safety of A-Part® Gel as an adhesion prophylaxis after major abdominal wall surgery, in comparison to an untreated control group. 60 patients undergoing an elective median laparotomy without prior abdominal surgery are randomly allocated into two groups of a 1:1- ratio. Safety parameter and primary endpoint of the study is the occurrence of wound healing impairment or peritonitis within 28 (+10) days after surgery. The frequency of anastomotic leakage within 28 days after operation, occurrence of adverse and serious adverse events during hospital stay up to 3 months and the rate of adhesions along the scar within 3 months are defined as secondary endpoints. After hospital discharge the investigator will examine the enrolled patients at 28 (+10) days and 3 months (±14 days) after surgery.DiscussionThis trial aims to assess, whether the intra-peritoneal application of A-Part® Gel is safe and efficacious in the prevention of post-surgical adhesions after median laparotomy, in comparison to untreated controls.Trial registrationNCT00646412

Esophageal replacement by interposition of pedicled ascending colon flap supplied by the inferior mesenteric artery

Colon interposition for esophageal replacement is indicated in patients with benign esophageal disease, in patients who require an esophago gastrectomy for a potential cure and in patients in whom the stomach is no longer available for replacement because of preceding surgery. In 30 patients we performed colon interposition grafts for esophageal replacement using a modified technique. This technique includes ligation of the middle and right colic artery, thereby creating an interposition graft of the whole ascending colon which receives blood exclusively from the left colic artery. The main advantage of this procedure is the length of the interposition graft. Preparation of the left colic flexure is no longer required. Nineteen patients had an esophagectomy, 11 patients an esophago-gastrectomy. Minor complications in this unselected patient group occurred six times (20%), and major complications were observed in seven patients (23.3%). Frequency of anastomotic leakage amounted to 13.3%, hospital mortality to 10%. Frequency of postoperative complications and hospital mortality of patients in whom a modified colon interposition was done is comparable with published data of unselected patient groups, which had either a standard colon interposition graft for esophageal replacement or a gastric pull-through procedure.
