Lymphedema Rates Following Axillary Lymph Node Dissection With and Without Immediate Lymphatic Reconstruction: A Prospective Trial.

BACKGROUND: Immediate lymphatic reconstruction (ILR) has been proposed to decrease lymphedema rates. The primary aim of our study was to determine whether ILR decreased the incidence of lymphedema in patients undergoing axillary lymph node dissection (ALND). METHODS: We conducted a two-site pragmatic study of ALND with or without ILR, employing surgeon-level cohort assignment, based on breast surgeons' preferred standard practice. Lymphedema was assessed by limb volume measurements, patient self-reporting, provider documentation, and International Classification of Diseases, Tenth Revision (ICD-10) codes. RESULTS: Overall, 230 patients with breast cancer were enrolled; on an intention-to-treat basis, 99 underwent ALND and 131 underwent ALND with ILR. Of the 131 patients preoperatively planned for ILR, 115 (87.8%) underwent ILR; 72 (62.6%) were performed by one breast surgical oncologist and 43 (37.4%) by fellowship-trained microvascular plastic surgeons. ILR was associated with an increased risk of lymphedema when defined as ≥10% limb volume change on univariable analysis, but not on multivariable analysis, after propensity score adjustment. We did not find a statistically significant difference in limb volume measurements between the two cohorts when including subclinical lymphedema (≥5% inter-limb volume change), nor did we see a difference in grade between the two cohorts on an intent-to-treat or treatment received basis. For all patients, considering ascertainment strategies of patient self-reporting, provider documentation, and ICD-10 codes, as a single binary outcome measure, there was no significant difference in lymphedema rates between those undergoing ILR or not. CONCLUSION: We found no significant difference in lymphedema rates between patients undergoing ALND with or without ILR.

Life-threatening Carotid Complications Caused by Extraluminal Migration of Ingested Foreign Bodies; a Case Report and Narrative Review of Literature.

Carotid complications resulting from extra-luminal migration of ingested foreign bodies (FB) are rare but potentially life-threatening. Previous data on the topic predominantly comprises isolated case reports, leaving a gap in comprehensive evidence necessary to guide clinical decision-making. In this article, we offer a narrative review alongside a novel case report, aimed at providing a broad, evidence-based perspective on the topic to guide clinical practice. The search strategy employed keywords related to carotid artery complications from ingested FB across the following electronic databases: PubMed, Scopus, Google Scholar, and Cochrane Central. Screening involved standardized data extraction by two independent reviewers, with a focus on abstracts meeting inclusion criteria and excluding non-English literature and non-relevant studies from further analysis. Moreover, we present a novel case report on the topic that was successfully managed using a unique surgical approach. Overall, a total of sixteen case reports were finally included, data on clinical presentations, diagnostic strategies and findings, surgical management and outcome were extracted, tabulated, and discussed. In carotid complications from extra-luminal migration of ingested FB, high clinical suspicion is crucial due to potentially mild symptoms and negative first-level examinations. Computed tomography (CT) scan plays a pivotal role for accurate diagnosis and surgical planning, along with neck ultrasound to detect complications. Tailored surgical strategies based on the severity of carotid involvement, including venous patch grafts in severe vessels involvement, are crucial for optimal patient outcomes. As a novelty, in our case report, carotid shunt was successfully employed instead of prolonged carotid clamping to reduce the risk of associated neurological sequelae. It could be concluded that, diagnosis and managing carotid complications from extra-luminal migration of ingested FB remains challenging and a multidisciplinary approach is warranted.

Uterine Anastomosis with Low Anterior Resection.

In this surgical teaching video, we demonstrate the technique of robot-assisted uterine anastomosis combined with low anterior resection in a 27-year-old patient with T2 node-positive rectal cancer. The patient had undergone uterine transposition for fertility preservation prior to upfront chemotherapy and radiation therapy for rectal cancer. In this video, we review the key steps of both surgical procedures. We emphasize robot trocar placement and docking, demonstrate optimal organ manipulation and tissue handling, and include key operative modifications and pearls for successful perioperative management.

Ideal suturing technique for robot-assisted microsurgical anastomoses.

The development of novel robotic devices specifically designed for open microsurgery leads to increasing applications in reconstructive procedures. While initial studies revealed improved precision and surgical ergonomics upon robotic assistance, surgical time was consistently observed to be increased. This study compares two robotic suturing techniques using the Symani Surgical System and RoboticScope in a preclinical setting, to further leverage the benefits of novel robotic devices in microsurgery. Six experienced microsurgeons performed three microvascular anastomoses with a "steady-thread" suturing technique and a "switch-thread" technique on 1.0-mm-diameter artificial silicone vessels. Time for anastomosis and participant's satisfaction with the techniques and robotic setup were recorded. Anastomosis quality and microsurgical skills were assessed using the Anastomosis Lapse Index and Structured Assessment of Microsurgery Skills. Lastly, technical error messages and thread ruptures were quantified. Knot tying was significantly faster and evaluated significantly better by participants using the steady-thread technique (4.11 ± 0.85 vs. 6.40 ± 1.83 min per anastomosis). Moreover, microsurgical skills were rated significantly better using this technique, while both techniques consistently led to high levels of anastomosis quality (2.61 ± 1.21 vs. 3.0 ± 1.29 errors per anastomosis). In contrast, the switch-thread technique was associated with more technical error messages in total (14 vs. 12) and twice as many unintended thread ruptures per anastomosis (1.0 ± 0.88 vs. 0.5 ± 0.69). This study provides evidence for the enhanced performance of a steady-thread suturing technique, which is suggested to be applied upon robot-assisted microsurgical procedures for optimized efficiency.

Incidence of anastomotic leakage using powered circular staplers versus manual circular staplers for left colorectal anastomosis: a cost-effectiveness analysis.

BACKGROUND: Colorectal anastomotic leakage causes severe consequences for patients and healthcare system as it will lead to increased consumption of hospital resources and costs. Technological improvements in anastomotic devices could reduce the incidence of leakage and its economic impact. The aim of the present study was to assess if the use of a new powered circular stapler is cost-effective. METHOD: This observational study included patients undergoing left-sided circular stapled colorectal anastomosis between January 2018 and December 2021. Propensity score matching was carried out to create two comparable groups depending on whether the anastomosis was performed using a manual or powered circular device. The rate of anastomotic leakage, its severity, the consumption of hospital resources, and its cost were the main outcome measures. A cost-effectiveness analysis comparing the powered circular stapler versus manual circular staplers was performed. RESULTS: A total of 330 patients were included in the study, 165 in each group. Anastomotic leakage rates were significantly different (p = 0.012): 22 patients (13.3%) in the manual group versus 8 patients (4.8%) in the powered group. The effectiveness of the powered stapler and manual stapler was 98.27% and 93.69%, respectively. The average cost per patient in the powered group was €6238.38, compared with €9700.12 in the manual group. The incremental cost-effectiveness ratio was - €74,915.28 per patient without anastomotic complications. CONCLUSION: The incremental cost of powered circular stapler compared with manual devices was offset by the savings from lowered incidence and cost of management of anastomotic leaks.

A minor tweak in transplant surgery protocols alters the cellular landscape of the arterial wall during transplant vasculopathy.

Introduction: Transplant vasculopathy (TV) is a major complication after solid organ transplantation, distinguished by an arterial intimal thickening that obstructs the vascular lumen and leads to organ rejection. To date, TV remains largely untreatable, mainly because the processes involved in its development remain unclear. Aortic transplantation in mice, used to mimic TV, relies on highly variable experimental protocols, particularly regarding the type of anastomosis used to connect the donor aorta to the recipient. While the amount of trauma undergone by a vessel can dramatically affect the resulting pathology, the impact of the type of anastomosis on TV in mice has not been investigated in detail. Methods: In this study, we compare the cellular composition of aortic grafts from BALB/C donor mice transplanted into C57BL/6J recipient mice using two different anastomosis strategies: sleeve and cuff. Results: While both models recapitulated some aspects of human TV, there were striking differences in the cellular composition of the grafts. Indeed, aortic grafts from the cuff group displayed a larger coverage of the neointimal area by vascular smooth muscle cells compared to the sleeve group. Aortic grafts from the sleeve group contained higher amounts of T cells, while the cuff group displayed larger B-cell infiltrates. Discussion: Together, these data indicate that a seemingly minor technical difference in transplant surgery protocols can largely impact the cellular composition of the graft, and thus the mechanisms underlying TV after aortic transplantation in mice.

Evaluating bacterial contamination and surgical site infection risks in intracorporeal anastomosis: Role of bowel preparation.

We recently read the study by Kayano et al on intracorporeal anastomosis (IA) for colon cancer, which assessed bacterial contamination and medium-term oncological outcomes and affirmed that IA is analogous to extracorporeal anastomosis in reducing intraperitoneal bacterial risk and achieving similar oncological results. Our commentary addresses gaps, particularly concerning bowel preparation and surgical site infections (SSIs), and highlights the need for comprehensive details on the bowel preparation methods that are currently employed, including mechanical bowel preparation, oral antibiotics (OA), their combination, and specific OA types. We emphasize the necessity for further analyses that investigate these methods and their correlation with SSI rates, to enhance clinical protocol guidance and optimize surgical outcomes. Such meticulous analyses are essential for refining strategies to effectively mitigate SSI risk in colorectal surgeries.

Magnetic compression anastomosis to restore biliary tract continuity after obstruction following major abdominal trauma: A case report.

BACKGROUND: The combination of magnetic compression anastomosis (MCA) and endoscopy has been used to treat biliary stricture after liver transplantation. However, its use for the treatment of complex biliary obstruction after major abdominal trauma has not been reported. This case report describes the successful use of MCA for the treatment of biliary obstruction resulting from major abdominal trauma. CASE SUMMARY: A 23-year-old man underwent major abdominal surgery (repair of liver rupture, right half colon resection, and ileostomy) following a car accident one year ago. The abdominal drainage tube, positioned at the Winslow foramen, was draining approximately 600-800 mL of bile per day. During the two endoscopic retrograde cholangiopancreatography procedures, the guide wire was unable to enter the common bile duct, which prevented placement of a biliary stent. MCA combined with endoscopy was used to successfully achieve magnetic anastomosis of the peritoneal sinus tract and duodenum, and then a choledochoduodenal stent was placed. Finally, the external biliary drainage tube was removed. The patient achieved internal biliary drainage leading to the removal of the external biliary drainage tube, which improved the quality of life. CONCLUSION: Magnetic compression technique can be used for the treatment of complex biliary obstruction with minimal operative trauma.

Fully ambulatory robotic single anastomosis duodeno-ileal bypass (SADI): 40 consecutive patients in a single tertiary bariatric center.

BACKGROUND: Single Anastomosis Duodeno-Ileal bypass (SADI) is becoming a key option as a revision procedure after laparoscopic sleeve gastrectomy (LSG). However, its safety as an ambulatory procedure (length of stay < 12 h) has not been widely described. METHODS: A prospective bariatric study of 40 patients undergoing SADI robotic surgery after LSG with same day discharge (SDD), was undertaken in April 2021. Strict inclusion and exclusion criteria were applied and the enhanced recovery after bariatric surgery protocol was followed. Anesthesia and robotic procedures were standardized. Early follow-up (30 days) analyzed postoperative (PO) outcomes. RESULTS: Forty patients (37 F/3 M, mean age: 40.3yo), with a mean pre-operative BMI = 40.5 kg/m2 were operated. Median time after LSG was 54 months (21-146). Preoperative comorbidities included: hypertension (n = 3), obstructive sleep apnea (n = 2) and type 2 diabetes (n = 1). Mean total operative time was 128 min (100-180) (mean robotic time: 66 min (42-85)), including patient setup. All patients were discharged home at least 6 h after surgery. There were four minor complications (10%) and two major complications (5%) in the first 30 days postoperative (one intrabdominal abscess PO day-20 (radiological drainage and antibiotic therapy) and one peritonitis due to duodenal leak PO day-1 (treated surgically)). There were six emergency department visits (15%), readmission rate was 5% (n = 2) and reintervention rate was 2.5% (n = 1) There was no mortality and no unplanned overnight hospitalization. CONCLUSIONS: Robotic SADI can be safe for SDD, with appropriate patient selection, in a high-volume center.

Surgical management of lymphedema: prophylactic and therapeutic operations.

Purpose of Review: Lymphedema is chronic limb swelling from lymphatic dysfunction and is currently incurable. Breast-cancer related lymphedema (BCRL) affects up to 5 million Americans and occurs in one-third of breast cancer survivors following axillary lymph node dissection. Compression remains the mainstay of therapy. Surgical management of BCRL includes excisional procedures to remove excess tissue and physiologic procedures to attempt improve fluid retention in the limb. The purpose of this review is to highlight surgical management strategies for preventing and treating breast cancer-related lymphedema. Recent findings: Immediate lymphatic reconstruction (ILR) is a microsurgical technique that anastomoses disrupted axillary lymphatic vessels to nearby veins at the time of axillary lymph node dissection (ALND) and has been reported to reduce lymphedema rates from 30% to 4-12%. Summary: Postsurgical lymphedema remains incurable. Surgical management of lymphedema includes excisional procedures and physiologic procedures using microsurgical technique. Immediate lymphatic reconstruction has emerged as a prophylactic strategy to prevent lymphedema in breast cancer patients.

Gastrointestinal functions after laparoscopic right colectomy with intracorporeal anastomosis: a pilot randomized clinical trial on effects of abdominal drain, prolonged antibiotic prophylaxis, and D3 lymphadenectomy with complete mesocolic excision.

PURPOSE: Routine use of abdominal drain or prolonged antibiotic prophylaxis is no longer part of current clinical practice in colorectal surgery. Nevertheless, in patients undergoing laparoscopic right hemicolectomy with intracorporeal anastomosis (ICA), it may reduce perioperative abdominal contamination. Furthermore, in cancer patients, prolonged surgery with extensive dissection such as central vascular ligation and complete mesocolon excision with D3 lymphadenectomy (altogether radical right colectomy RRC) is called responsible for affecting postoperative ileus. The aim was to evaluate postoperative resumption of gastrointestinal functions in patients undergoing right hemicolectomy for cancer with ICA and standard D2 dissection or RRC, with or without abdominal drain and prolonged antibiotic prophylaxis. METHODS: Monocentric factorial parallel arm randomized pilot trial including all consecutive patients undergoing laparoscopic right hemicolectomy and ICA for cancer, in 20 months. Patients were randomized on a 1:1:1 ratio to receive abdominal drain, prolonged antibiotic prophylaxis or neither (I level), and 1:1 to receive RRC or D2 colectomy (II level). Patients were not blinded. The primary aim was the resumption of gastrointestinal functions (time to first gas and stool, time to tolerated fluids and food). Secondary aims were length of stay and complications' rate. CLINICALTRIALS: gov no. NCT04977882. RESULTS: Fifty-seven patients were screened; according to sample size, 36 were randomized, 12 for each arm for postoperative management, and 18 for each arm according to surgical techniques. A difference in time to solid diet favored the group without drain or antibiotic independently from standard or RRC. Furthermore, when patients were divided with respect to surgical technique and into matched cohorts, no differences were seen for primary and secondary outcomes. CONCLUSION: Abdominal drainage and prolonged antibiotic prophylaxis in patients undergoing right hemicolectomy for cancer with ICA seem to negatively affect the resumption of a solid diet after laparoscopic right hemicolectomy with ICA for cancer. RRC does not seem to influence gastrointestinal function recovery.

First case report of intestinal lymphangiectasia with refractory bleeding from the duodenum, successfully treated by intra-abdominal lymphaticovenous anastomosis with venous ligation.

Intestinal lymphangiectasia (IL) is a protein-losing enteropathy (PLE) that occasionally leads to gastrointestinal bleeding (GIB). We encountered a 41-year-old female with a 9-year history of duodenal IL with PLE and GIB that progressively worsened. Despite a diet, supplemented with medium-chain triglycerides, antiplasmin therapy, oral corticosteroids, octreotides, sirolimus, and repeated endoscopic hemostasis, her symptoms remained uncontrolled, leading to blood transfusion dependence. Lymphangiography revealed significant leakage from abnormal abdominal lymph vessels into the duodenal lumen. The patient subsequently underwent an abdominal-level lymphaticovenous anastomosis combined with local venous ligation. This approach resulted in a dramatic improvement and sustained resolution of both the PLE and GIB. More than 6 months after surgery, the patient remained free of symptoms and blood transfusion dependence.

Minimally invasive left colectomy with total intracorporeal anastomosis versus extracorporeal anastomosis. A single center cohort study. Stage 2b IDEAL framework for evaluating surgical innovation.

PURPOSE: Performing intracorporeal anastomoses in minimally invasive colon surgery appears to provide better short-term outcomes for patients with colon cancer. The aim of the study is to compare surgical aspects and short-term outcomes between intracorporeal and extracorporeal techniques in left colectomies with both laparoscopic and robotic approaches and evaluate advantages and disadvantages of intracorporeal anastomosis according to IDEAL framework (Exploration, stage 2b). METHODS: This is a single center, ambispective cohort study comparing total intracorporeal anastomosis (TIA) and standard surgery with extracorporeal anastomosis (EA). Patients with colon cancer treated by left colectomy, sigmoidectomy and high anterior resection by total intracorporeal anastomosis between May 2020 and January 2023 without exclusion criteria were prospectively included in a standardized database. Short-term outcomes in the group undergoing TIA were compared with a historical EA cohort. The main assessment outcomes were intraoperative complications, postoperative morbidity according to the Clavien-Dindo scale and the comparison of pathological. We conducted a preliminary comparative study within the TIA group between approaches, a primary analysis between the two anastomotic techniques, and a propensity score matched analysis including only the laparoscopic approach, between both anastomotic techniques. RESULTS: Two hundred and forty-six patients were included: 103 who underwent TIA, 35 of them with laparoscopic approach and 68 with robotic approach, and a comparison group comprising another 103 eligible consecutive patients who underwent laparoscopic EA. There were no statistically significant differences between the two groups in terms of demographic variables. No statistically significant differences were observed in anastomotic dehiscence. Intraoperative complications are fewer in the TIA group, with a higher C-Reactive Protein levels. Relevant anastomotic bleeding and the number of retrieved lymph nodes were higher in EA group. Nevertheless, no differences were observed in terms of overall morbidity. CONCLUSION: Minimally invasive left colectomy with intracorporeal resection and anastomosis is technically feasible and safe suing either a laparoscopic or a robotic approach. Clinical data from this cohort demonstrate outcomes comparable to those achieved through the conventional EA procedure in relation to postoperative morbidity and oncological efficacy, with indications suggesting that the utilization of robotic-assisted techniques may play a contributing role in enhancing overall treatment outcomes.

Efficiency and safety of single anastomosis sleeve ileal (SASI) bypass in the treatment of obesity and associated comorbidities: a systematic review and meta-analysis.

INTRODUCTION: The Single Anastomosis Sleeve Ileal (SASI) bypass is a new bariatric surgery corresponding to an adaptation of the Santoro approach, consisting of a sleeve gastrectomy (SG) followed by loop gastroileostomy. Therefore, we aimed to systematically assess all the current literature on SASI bypass in terms of safety, weight loss, improvement in associated comorbidities, and complications. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) recommendations, we conducted a systematic review and meta-analysis by searching three databases (PubMed, Scopus, and Web of Science). We performed a meta-analysis of risk ratios and mean differences to compare surgical approaches for excessive weight loss, improvement/remission in type 2 diabetes mellitus (T2DM), hypertension (HT), dyslipidemia (DL), obstructive sleep apnea (OSA), and complications. Heterogeneity was assessed using the I2 statistic. RESULTS: Eighteen studies were included in the qualitative analysis and four in the quantitative analysis, comparing SASI bypass with SG and One-Anastomosis Gastric Bypass (OAGB). A comparison between Roux-en-Y Gastric Bypass (RYGB) and SASI bypass could not be performed. Compared to SG, the SASI bypass was associated with improved weight loss (MD = 11.32; 95% confidence interval (95%CI) [7.89;14.76]; p < 0.0001), and improvement or remission in T2DM (RR = 1.35; 95%CI [1.07;1.69]; p = 0.011), DL (RR = 1.41; 95%CI [1.00;1.99]; p = 0.048) and OSA (RR = 1.50; 95%CI [1.01;2.22]; p = 0.042). No statistically significant differences in any of the assessed outcomes were observed when compared with OAGB. When compared to both SG and OAGB, the complication rate of SASI was similar. CONCLUSION: Although studies with longer follow-up periods are needed, this systematic review and meta-analysis showed that SASI bypass has a significant effect on weight loss and metabolic variables. Variations in outcomes between studies reinforce the need for standardization.

Percutaneous Endovascular Creation of a Neo-arteriovenous Fistula in Dysfunctional Hemodialysis Fistulas.

PURPOSE: Arteriovenous fistulas (AVF) is the preferred type of hemodialysis access, but when an arteriovenous anastomosis (AVA) calcifies, surgical revision of the AVF may be required. We report a technique to create percutaneous artery-to-vein intervascular neo-fistulas for re-anastomosis of AVA and evaluate its safety and efficacy. MATERIALS AND METHODS: 9 patients who failed either guidewire navigation or conventional balloon dilation for calcified AVA stenosis/occlusion underwent a salvage procedure of their dialysis shunt by the percutaneous creation of a new arteriovenous fistula. Needle puncture of the adjacent supplying artery and outflow vein under ultrasonographic and/or fluoroscopic guidance was performed and followed by balloon dilation, with or without stent graft placement. The detailed techniques, technical success, primary neo-fistula patency, primary and secondary access patency rates were reported herein. RESULTS: Technical success was achieved in 100% of the 9 patients treated (7 neo-fistulas with stents and 2 neo-fistulas without stent placement). The median primary neo-fistula and access patencies were 15 and 5 months, respectively. The primary neo-fistula patency rates at 6, 12, and 18 months were 72.9%, 54.7% and 27.9%, respectively, with secondary neo-fistula and access patency rates of 72.9%, 72.9% and 72.9%, respectively. One delayed complication of pseudoaneurysm formation occurred, which was managed by the successful endovascular deployment of a stent graft on an out-patient basis. CONCLUSION: Percutaneous artery-to-vein intervascular neo-fistula creation is feasible for re-anastomosing calcified AVA, with low adverse effects and acceptable primary neo-fistula and secondary access patency.

Endoscopic Balloon Dilatation of Ileal Pouch-Anal Anastomosis Strictures in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.

BACKGROUND: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the treatment of choice for medically refractory inflammatory bowel disease (IBD). In this systematic review and meta-analysis, we assess outcomes and safety of endoscopic balloon dilatation (EBD) for IPAA strictures. METHODS: A systematic search of numerous databases was performed through June 2023 to identify studies reporting on the outcomes of EBD in pouch-related strictures. Outcomes included technical success, clinical success at index dilation and in pouch retention, recurrence of symptoms post-EBD, and adverse events of EBD. Meta-analysis was performed using a random-effects model, and results were expressed in terms of pooled rates along with relevant 95% confidence intervals (CIs). Heterogeneity was assessed using Cochran Q statistical test with I2 statistics. RESULTS: Seven studies with 504 patients were included. The pooled rate of technical success and clinical success of index dilatation was 98.9% (95% CI, 94.8-99.8%; I20%) and 30.2% (95% CI, 7.1-71%; I20%), respectively. The pooled rate of clinical success in pouch retention without the need for additional surgery was 81.4% (95% CI, 69.6-89.3%; I272%). The pooled failure rate of EBD was 18.6% (95% CI, 10.7-30.4%, I272%). The pooled rate of recurrence of symptoms after index dilatation was 58.9% (95% CI, 33.3-80.5%; I213%). The pooled rate of serious adverse events was 1.8% (95% CI, 1-3.5%, I20%). No deaths related to EBD were reported. CONCLUSIONS: Endoscopic balloon dilatation is safe and highly effective for management of IPAA strictures. Additional studies are needed to compare its efficacy with surgical interventions.

In this meta-analysis of 7 studies consisting of 504 inflammatory bowel disease patients with ileal pouch-anal anastomosis strictures, endoscopic balloon dilation was highly safe and effective with excellent clinical and technical success rates.

Implantation cyst appearing more than 30 years after gastrectomy.

Implantation cyst is often reported to be a delayed complication after colorectal surgery. This report presents a 70-year-old man undergoing gastrectomy 33 years earlier for an acute gastric ulcer. His endoscopic finding showed a submucosal tumor about 20 mm in diameter at the gastro-jejunal anastomosis. Endoscopic ultrasonography showed that the tumor was a cystic mass that was continuous from the third layer, but there were no existences of internal substantial nodules, indicating that the tumor was diagnosed as implantation cyst. This is the first report showing that implantation cyst can occur at gastro-jejunal anastomosis. We should take into account the occurrence of implantation cyst, when we encounter a submucosal tumor at gastro-jejunal anastomosis after surgery even if a long period has passed.

Epiploic steal: is this concept the key to reducing colorectal anastomotic leak rates?

PURPOSE: Ensuring optimal colonic perfusion is a critical step in every colorectal anastomosis. The aim of this study is to describe the concept of epiploic steal. METHODS: A literature review was performed to identify studies evaluating anastomotic blood supply. The fundamental principle of epiploic steal is outlined. RESULTS: Epiploic steal has not been previously evaluated in the literature, and likely has a negative effect on colonic blood supply. Resection of colonic epiploicae may improve perfusion at the distal most lengths of a mobilised colonic conduit where the anastomosis requires it. CONCLUSION: This novel concept has the potential to change practice and reduce colorectal anastomotic leak rates. Further clinical studies are required.
