Abstract
Crohn's disease is a complex condition that confers a significant risk of requiring multiple surgeries. Questions that surgeons must frequently answer include: which patients benefit from diversion? Does monoclonal antibody therapy increase post-operative complications? And, are there surgical techniques that can prevent the recurrence of Crohn's disease? This review examines current data to answer these questions.

Abstract
BACKGROUND AND AIMS Postoperative recurrence is a major concern in Crohn's disease. The Kono-S anastomosis has been described to reduce the rate of recurrence. However, the level of evidence for its effectiveness remains low. The KoCoRICCO study aimed to compare outcomes between Kono-S anastomosis and conventional anastomosis in two nationwide, prospective cohorts. METHODS Adult patients with Crohn's disease, who underwent ileocolonic resection with Kono-S anastomosis, were prospectively included in seven referral centres between 2020 and 2022. Patients with conventional side-to-side anastomosis were enrolled from a previously published cohort. A propensity score analysis was performed to compare recurrence at first endoscopy in a matched 1:2 ratio population. RESULTS A total of 433 patients with ileocolonic anastomosis were enrolled, of whom 155 had a Kono-S anastomosis. Before matching, both groups were unbalanced for preoperative, intraoperative, and postoperative characteristics. After matching patients with available endoscopic follow-up, endoscopic recurrence ≥i2 was found in 47.5% of the Kono-S group and 44.3% of the conventional side-to-side group [p = 0.6745]. CONCLUSIONS The KoCoRICCO study suggests that Kono-S anastomosis does not reduce the risk of endoscopic recurrence in Crohn's disease compared with conventional side-to-side anastomosis. Further research with a longer follow-up is necessary to determine whether there is a potential benefit on surgical recurrence.

Abstract
BACKGROUND The mesentery has recently been implicated in the pathophysiology of Crohn's disease (CD), and several techniques have been developed to target the mesentery to reduce its influence on recurrence. We aimed to describe short-term safety and feasibility after these approaches. METHODS This is a comparative, retrospective, single-center cohort study of consecutive CD patients undergoing primary or redo ileocolic resection from 2015 to 2022 with Kono-S anastomosis (KSA), extended mesenteric excision (EME) only, or both: mesenteric excision and exclusion (MEE). RESULTS 186 patients underwent KSA (n = 74), EME (n = 66), or MEE (n = 46). The groups had comparable baseline characteristics. The MEE group operative time was longer (median: 187 vs. KSA 170, EME 152 min, p < 0.01). Postoperatively, the groups had similar lengths of stay (median 4 days), readmissions (9.1 %), major postoperative complications (6.5 %), and anastomotic leaks (1.1 %). CONCLUSION Targeting the mesentery with novel surgical approaches for ileocolic Crohn's disease was safe and feasible for short-term follow-up.

Abstract
Up to 50% of patients with Crohn's disease develop a stricture within 10 years of diagnosis. Crohn's strictures can compose of inflammation, fibrosis or smooth muscle expansion and usually a combination of these. There have been numerous new developments in imaging modalities in determining the composition of Crohn's strictures. Magnetic resonance imaging remains the best upfront imaging modality to characterize Crohn's strictures. Gastrointestinal ultrasound (GIUS) has an increasing role in clinical practice, particularly for monitoring stricture response as a treat-to-target tool. Novel imaging techniques to differentiate between fibrosis and inflammatory strictures have been developed including contrast-enhanced GIUS, strain or shear wave elastography with GIUS and multiple new magnetic resonance imaging (MRI) protocols, including diffusion weighted, delayed contrast enhancement and magnetization transfer MR protocols. However, these techniques require further validation and standardization. Regarding therapeutics, anti-tumor necrosis agents with a treat-to-target strategy have the highest quality evidence in treating strictures and can lead to stricture regression in some cases. Endoscopic balloon dilatation remains a mainstay in the treatment algorithm of treating predominantly fibrostenotic Crohn's strictures, particularly those which are symptomatic, < 5 cm in length and not causing prestenotic dilatation. Endoscopic balloon dilatation has greater effectiveness in anastomotic strictures. Surgery remains an important treatment option in Crohn's strictures, with segmental resection and stricturoplasty having their own advantages and disadvantages. Kono-S anastomosis may be superior to conventional anastomosis for endoscopic recurrence; however, further high-quality studies are required to confirm this. Using risk stratification models such as the BACARDI risk model is important to guide management decisions between a medical and surgical approach. Early post-operative medical prophylaxis with an advanced therapy is an important consideration to prevent disease recurrence. This review expands on the above topics, highlights research gaps and provides a suggested investigation and management pathway in stricturing Crohn's disease.

Abstract
OBJECTIVES About 24% of children with Crohn's Disease (CD) require surgery. In 2003, Kono et al. described a novel anastomosis reported to decrease the rate of anastomotic CD recurrence. Subsequent studies have reproduced these outcomes, but none has demonstrated its effect in pediatric patients. This study evaluates short-term outcomes of pediatric patients following ileocolic resection and Kono-S anastomosis. METHODS A retrospective review of patients < 18 years old who underwent ileocolic resection followed by Kono-S anastomosis compared with those who underwent a stapled anastomosis. RESULTS Nine Kono-S patients were matched with nine patients preceding them who received traditional side-to-side and end-to-side anastomoses. All patients underwent minimally invasive surgery. Demographics, pre-operative medication usage, and symptom profiles were not significantly different. Traditional anastomosis (TA) patients had longer lengths of stay (4.6 vs 2.9 days; p = 0.03) but had no statistically significant differences in blood loss, procedure length, and pathologic findings. One Kono-S patient had a superficial surgical site infection, and one TA patient had an anastomotic leak requiring reoperation within 30 days. More TA patients experienced post-operative symptoms at both 30-day and 6-month follow-up (66.7% vs 33.3%; p = 0.16 and 77.8% vs 25%; p = 0.03). CONCLUSION The Kono-S anastomosis appears to be safe in pediatric CD when compared to traditional stapled anastomoses.

Abstract
BACKGROUND Patients with Crohn's disease (CD) after ileocolic resection may develop an endoscopic postoperative recurrence (ePOR) that reaches 40% to 70% of incidence within 6 months. Recently, there has been growing interest in the potential effect of anastomotic configurations on ePOR. Kono-S anastomosis has been proposed for reducing the risk of clinical and ePOR. Most studies have assessed the association of ileocolonic anastomosis and ePOR individually, while there is currently limited data simultaneously comparing several types of anastomosis. Therefore, we performed a systematic review and meta-analysis to assess the impact of different ileocolonic anastomosis on ePOR in CD. METHODS We searched PubMed and Embase from inception to January 2023 for eligible studies reporting the types of anastomoses and, based on these, the rate of endoscopic recurrence at ≥6 months. Studies were grouped by conventional anastomosis, including side-to-side, end-to-end, and end-to-side vs Kono-S, and comparisons were made between these groups. Pooled incidence rates of ePOR were computed using random-effect modelling. RESULTS Seventeen studies, with 2087 patients who underwent ileocolic resection for CD were included. Among these patients, 369 (17,7%) Kono-S anastomoses were performed, while 1690 (81,0%) were conventional ileocolic anastomosis. Endoscopic postoperative recurrence at ≥6 months showed a pooled incidence of 37.2% (95% CI, 27.7-47.2) with significant heterogeneity among the studies (P < .0001). In detail, patients receiving a Kono-S anastomosis had a pooled incidence of ePOR of 24.7% (95% CI, 6.8%-49.4%), while patients receiving a conventional anastomosis had an ePOR of 42.6% (95% CI, 32.2%-53.4%). CONCLUSIONS Kono-S ileocolic anastomosis was more likely to decrease the risk of ePOR at ≥6 months compared with conventional anastomosis. Our findings highlight the need to implement the use of Kono-S anastomosis, particularly for difficult to treat patients. However, results from larger randomized controlled trials are needed to confirm these data.

Abstract
BACKGROUND Surgical resection rates remain high in Crohn's disease (CD). Reducing postoperative recurrence (POR) is challenging. Besides drug therapy, the surgical anastomosis technique may reduce POR. We aimed to compare the endoscopic POR rate after Kono-S vs standard ileocolic anastomosis. METHODS The study included all consecutive CD patients operated on for ileocolic resection with a Kono-S anastomosis between February 2020 and March 2022. These patients were prospectively followed, and colonoscopy was performed 6 to 12 months after surgery. Patients were compared with a historical cohort of patients operated on with a conventional anastomosis in the same center. The primary end point was endoscopic POR (Rutgeerts score ≥i2). Factors associated with POR were assessed by univariate and multivariable analyses. RESULTS A total of 85 patients were included, 30 in the Kono-S group and 55 in the control group. At baseline, there was no significant difference between the 2 groups regarding CD characteristics or known POR risk factors, including previous exposure to biologics. At 6 to 12 months, endoscopic POR rate did not differ significantly between groups (56.7% in the Kono-S group vs 49.1% in the control group; P = .50), nor did endoscopic POR according to the modified Rutgeerts score ≥i2b (46.7% in the Kono-S group vs 40% in the control group; P = .55). Severe endoscopic POR rates were 23.3% and 18.2% in each group, respectively. Clinical recurrence rate was similar in both groups, and no recurrent surgery occurred. By multivariable analysis, the type of anastomosis was not associated with endoscopic POR (OR, 1.229; 95% CI, 0.461-3.274, P = .68); however, postoperative treatment with anti-TNF was (OR, 0.337; 95% CI, 0.131-0.865 P = .02). CONCLUSIONS Kono-S anastomosis was not associated with a reduced rate of endoscopic POR. These results warrant confirmation in prospective, randomized, multicenter studies.

Abstract
BACKGROUND Postoperative recurrence is frequently encountered in the management of patients with Crohn's disease and is most often found at the anastomotic site. A novel technique, the Sasaki-W anastomosis, is an antimesenteric cutback end-to-end isoperistaltic anastomosis. We report a patient with Crohn's disease who underwent partial intestinal resection for postoperative anastomotic stenosis, reconstructed with the Sasaki-W anastomosis, after initial intestinal resection reconstructed with a Kono-S anastomosis. CASE PRESENTATION A 30-year-old male was diagnosed with Crohn's disease and treated with mesalamine and adalimumab, and he underwent ileocecal resection using the Kono-S anastomosis at the time of diagnosis. He was treated with infliximab without any symptoms or recurrence for 7 years. He was admitted presenting with upper abdominal pain. Physical examination showed mild tenderness and distension in the upper abdomen. Laboratory data showed no remarkable findings. Computed tomography scan showed wall thickening in the ileum with proximal dilation and fluid retention. Non-operative management with antibiotics and fasting did not improve the symptoms within 7 days. Ten days after admission, ileocecal resection reconstructed with the Sasaki-W anastomosis was performed. At operation, there was a 15-cm intestinal stenosis at the site of the previous Kono-S anastomosis. The transverse colon and ileum were reconstructed with the Sasaki-W anastomosis. The postoperative course was uneventful, and the patient was discharged 17 days postoperatively. The patient had no obstructive symptoms and no findings consistent with bowel obstruction were observed on computed tomography scan one year postoperatively. CONCLUSIONS The Sasaki-W anastomosis is a viable option for intestinal reconstruction in patients with postoperative recurrence after a Kono-S anastomosis.

Abstract
BACKGROUND Heineke-Mikulicz (HM) strictureplasty is commonly used to treat short stenoses in Crohn's disease. However, the degree to which intestinal motility is maintained remains unclear. We compared the peristalsis and transport capacity of the sutured intestines with HM configuration and transverse (TS) and longitudinal (LS) incisions. METHODS The intestinal diameter, intraluminal pressure, and bead transit time of each sutured group were compared with that of the non-treatment (NT) group in the isolated proximal colon of rats. Propulsive contractions were induced using hydroxy-?-sanshool (HAS), a constituent of Japanese pepper. RESULTS There was no change in the intestinal diameter between HM, TS, and NT groups ; however, it was significantly narrowed at the suture site and its distal side in the LS group. After HAS administration, the intestinal diameter at the suture site in the HM group was higher than that in the LS group. The intraluminal pressure was higher and the transit time was shorter in the HM group compared to those in the LS group. CONCLUSIONS The HM configuration, which widens the incision site and distal diameter and shortens the cut surface of the circular muscle in the longitudinal direction, may help maintain basal and HAS-induced intestinal peristalsis and motility.

Abstract
INTRODUCTION The rates of postoperative recurrence following ileocecal resection due to Crohn's disease remain highly relevant. Despite this fact, while the Kono-S anastomosis technique initially demonstrated promising results, robust evidence is still lacking. This study aimed to analyze the short- and long-term outcomes of the Kono-S versus side-to-side anastomosis. METHODS A retrospective single-center study was performed including all patients who received an ileocecal resection between 1 January 2019 and 31 December 2021 at the Department of Surgery at the University Hospital of Wuerzburg. Patients who underwent conventional a side-to-side anastomosis were compared to those who received a Kono-S anastomosis. The short- and long-term outcomes were analyzed for all patients. RESULTS Here, 29 patients who underwent a conventional side-to-side anastomosis and 22 patients who underwent a Kono-S anastomosis were included. No differences were observed regarding short-term postoperative outcomes. The disease recurrence rate postoperatively was numerically lower following the Kono-S anastomosis (median Rutgeert score of 1.7 versus 2.5), with a relevantly increased rate of patients in remission (17.2% versus 31.8%); however, neither of these results reached statistical significance. CONCLUSION The Kono-S anastomosis method is safe and feasible and potentially decreases the severity of postoperative disease remission.

Abstract
Postoperative recurrence (POR) rates after resection for Crohn's disease (CD) are high. Whether the type of anastomosis affects POR is still debated. Recently, an anti-mesenteric hand-sewn end-to-end anastomosis (Kono-S) has been proposed as an additional measure to reduce recurrence. A randomized controlled trial demonstrated a significant reduction of endoscopic and clinical POR when the Kono-S anastomosis was compared to stapled ileocolic side-to-side anastomosis. However the hand- sewn technique might potentially limit use of this new type of anastomosis. The aim of this paper was to illustrate the technique of a totally stapled Kono-S anastomosis, and to discuss its potential advantages in surgery for CD.

Abstract
BACKGROUND Since its first description, the role of surgery in Crohn's disease (CD) has always been controversial; in fact, it has been mainly considered as a gastroenterological disease for long time. Nevertheless, despite great advances in medical therapy, up to 70-80% of patients with CD will require surgery in their lifetime and up to 30% of them will undergo repeated surgeries due to recurrences. For these reasons, the idea of surgery as a tool in the therapeutic armamentarium to consider even in the early stage of the disease has progressively spread in the last decades, even corroborated by reports showing how primary surgery is able to definitively treat around half of the patients at long-term follow-up. More surgeons are nowadays more and more involved in developing techniques to reduce recurrences that have always been considered as part of the natural history of the disease so far. SUMMARY In this review, we will go through the role of surgery in the management of CD, showing the potential benefits of an early surgical approach as well as the impact of surgical research in the natural history of the disease. From this standpoint, we will show the role of different anastomotic configurations, emphasizing how more and more data are definitively establishing the impact of the novel Kono-S anastomosis in reducing endoscopic and surgical recurrence. Mesentery-based surgery is a novel and appealing surgical perspective, but more data are required. KEY MESSAGES Surgery has demonstrated to be a crucial tool in the therapeutic armamentarium for the management of CD. Early surgery and novel surgical techniques, such as the Kono-S anastomosis, may have an impact on the natural history of the disease, including the possibility to prevent recurrences.

Abstract
Patients with Crohn's disease (CD) often require surgical resection due to complications, such as strictures and abscesses, or disease refractory to medical therapy. To understand the evolving management of patients with CD after surgery, we outline the risk factors for postoperative recurrence, advances in postoperative endoscopic evaluation and characterization of recurrence, noninvasive methods of assessing postoperative recurrence, use of postoperative prophylactic medical therapy including newer biologics, and novel surgical methods to reduce postoperative recurrence. The Rutgeerts score (RS) was developed to predict progression of disease based on endoscopic appearance postoperatively and to guide medical therapy. However, this scoring system groups ileal and anastomotic lesions into the same category. A modified RS was developed to separate lesions isolated to the anastomosis and those in the neo-terminal ileum to further understand the role of anastomotic lesions in CD progression. Additional scoring systems have also been evaluated to better understand these differences. In addition, noninvasive diagnostic methods, such as small bowel ultrasound, have high sensitivity and specificity for the detection of postoperative recurrence and are being evaluated as independent methods of assessment. Studies have also shown a reduction in endoscopic recurrence with postoperative anti-TNFα therapy. However, preoperative exposure to anti-TNFα therapy may impact postoperative response to these medications, and therefore, determining optimal postoperative prophylaxis strategy for biologic-experienced patients requires further exploration. Lastly, new surgical modalities to reduce postoperative recurrence are currently being investigated with preliminary data suggesting that an antimesenteric functional end-to-end anastomosis (Kono-S) may decrease postoperative recurrence.

Abstract
The management of Crohn's disease has evolved significantly over the past 20 years. The arrival of biologic therapies has altered not only the management and outcomes but also rates for refractory disease requiring surgery. New surgical techniques have paralleled these medical advances, and this article will provide an overview of these new modalities as well as their outcomes. This is the first of a three-part series and will focus on terminal ileal and ileocolic disease.

Abstract
AIM Recurrence after surgery for Crohn's disease is common. Anastomotic configuration may influence recurrence and the mesentery may be key. Recently the Kono-S anastomosis and radical mesenteric excision have been proposed as methods of reducing recurrence. We analysed the literature pertaining to these novel techniques. METHOD We searched MEDLINE, Embase and the Cochrane Library for, and selected, studies evaluating Kono-S anastomosis and/or radical mesenteric excision in Crohn's disease. We assessed methodological quality and risk of bias using the Cochrane risk of bias tool for randomized controlled trials and the Joanna Briggs Institute tool for nonrandomized trials. A narrative synthesis was used to summarize the findings. RESULTS Nine studies (896 patients) were identified. Apart from one randomized controlled trial with a low risk of bias the overall level of evidence was poor (Grade IV). The Kono-S anastomosis was associated with a lower incidence of endoscopic and surgical recurrence (0%-3.4% vs 15%-24.4% respectively). Complications, particularly anastomotic leak rate, were also lower (1.8% vs 9.3% respectively). Evidence from a single poor quality study suggested that mesenteric excision may reduce surgical recurrence rates compared with mesentery preservation. CONCLUSION The existing literature suggests that the Kono-S anastomosis is safe and may reduce endoscopic and surgical recurrence, but level of evidence is mainly poor. One element of the Kono-S technique, preservation of the mesentery, may be detrimental to recurrence. Further, higher quality, studies are required to investigate these techniques. Such studies should consider the impact of the degree of mesenteric resection in addition to the anastomosis on disease recurrence.

Abstract
Purpose The most frequent long-term complication after ileocecal resection in Crohn’s disease is anastomotic recurrence and subsequent stenosis. Recurrence typically begins at the site of the anastomosis, raising the question of whether the surgical technique of the anastomosis could affect recurrence rates. Kono-S anastomosis is a hand-sewn antimesenteric functional end-to-end anastomosis that offers a wide lumen that is well accessible for endoscopic dilatation. The purpose of our study is to review the rate of postoperative complications almost 2 years after the introduction of this technique. Materials and methods This is a prospective single-center cohort study of all consecutive patients with Crohn’s disease undergoing ileocecal resection. Patients’ characteristics as well as specific data for the surgical procedure and short-term outcome were evaluated. Results Thirty patients were operated for Crohn’s disease of the terminal ileum (n = 24) or anastomotic recurrence (n = 6). Postoperative complications with a Clavien-Dindo Score ≥ IIIb were observed in three patients. One patient showed a hemorrhage and underwent surgical hemostasis. Two patients developed anastomotic leakage; in both cases, ileostomy was created after resection of the anastomosis. The median hospital stay was 9 days (IQR 7–12). A comparison with a historic group of conventionally operated patients of our hospital revealed no differences in short-term results except for the duration of surgery. Conclusion The Kono-S anastomosis is associated with acceptable short-term results, complications, and recurrence rates comparable with the established anastomotic techniques. Longer operation times are observed, but the few published studies concerning long-term recurrence are promising.

Abstract
BACKGROUND Anastomotic surgical recurrence after bowel resection in Crohn's disease patients is problematic. This study was performed to evaluate the increased risk of anastomotic surgical recurrence. METHODS From 2006 to 2016, we performed anastomoses in 215 consecutive Crohn's disease patients. The cohort was divided into two groups: Kono-S anastomosis (n = 117) and end-to-end anastomosis (n = 98). Multivariate analysis of predictors of anastomotic surgical recurrence and Kaplan-Meier analysis for the 5-year anastomotic surgical recurrence rate were evaluated. RESULTS The two groups showed no statistically significant differences in patient backgrounds. During a median follow-up of 54 months, 28 patients required anastomotic surgical recurrence [4 (3.4%) in the Kono-S group and 24 (24.4%) in the end-to-end group]. Six leaks (5.1%) were detected in the Kono-S group and 17 leaks (17.3%) in the end-to-end group; all were successfully treated conservatively. End-to-end anastomosis, leakage, age < 45 years, and body mass index of ≥ 18 kg/m2 at the first surgery had a higher risk of anastomotic surgical recurrence. Kono-S anastomosis significantly reduced the risk of anastomotic surgical recurrence after 1 year (odds ratio, 0.14). Anastomotic leakage influenced anastomotic surgical recurrence within 1 year (odds ratio, 4.84). The 5-year surgery-free survival rate at the anastomosis site with Kono-S anastomosis (95.0%) was significantly higher than that with end-to-end anastomosis (81.3%; P < 0.001). CONCLUSIONS Anastomotic leakage after bowel resection in Crohn's disease patients increased anastomotic surgical recurrence within 1 year, and Kono-S anastomosis is associated with a low risk of anastomotic surgical recurrence after > 1 year.

Abstract
INTRODUCTION The Kono-S (antimesenteric functional end-to-end handsewn) anastomosis has been used for Crohn's disease in Japan and the USA since 2003 and 2010, respectively. This technique was designed to reduce the risk of anastomotic surgical recurrence. This study reviews the outcomes a decade after the introduction of the Kono-S anastomosis to clinical practice. METHODS This study was conducted at five hospitals (four in Japan and one in the USA). A total of 187 patients in Japan (144 patients, group J) and the USA (43 patients, group US) who underwent Kono-S anastomosis for Crohn's disease between September 2003 and September 2011 were included. RESULTS With a median follow-up of 65 months, two surgical anastomotic recurrences have occurred in group J. Kaplan-Meier analysis showed that 5 and 10 years surgical recurrence-free survival rate was 98.6% in group J. No surgical anastomotic recurrences have been detected in group US with a median follow-up of 32 months. The Kono-S anastomosis was technically feasible and performed in all patients. CONCLUSION The Kono-S anastomosis appears to be safe and effective in reducing the risk of surgical recurrence in Crohn's disease.
