Establishing access across a post-liver transplant anastomotic obstruction is paramount to allow future management with serial dilatation and to avoid surgical interventions. Several techniques have been reported to facilitate crossing complete anastomotic obstructions. Here, we report a case of successful off-label use of a vascular re-entry device to cross a complete anastomotic obstruction in a child after failed antegrade and retrograde attempts.

Background: Curative resection with adequate margins is a treatment principle in gastroesophageal junction cancers. There is still no comprehensive agreement on the length of the negative proximal margin after total gastrectomy in Siewert II and III tumors. Extending the proximal negative margin in this anatomical region is very difficult in some cases and can cause more complications for the patients. This study aimed to investigate the influence of the negative proximal margin length on the local anastomotic recurrence in gastroesophageal junction (GEJ) adenocarcinoma in a referral cancer center in Iran.Methods: In a prospective cross-sectional study, 35 patients with GEJ Sievert II and III adenocarcinomas who underwent total radical gastrectomy from 2017 to 2020 were included. Proximal margin length was measured immediately after resection in the operation room. Then, patients were evaluated for local recurrence at the anastomosis site after two years by endoscopic examination. The relationship between negative proximal margin length, local recurrence rate, and overall survival was evaluated.Results: From 35 patients 29 (82.9%) cases had negative proximal margins, and 6 (17.1%) cases had positive proximal margins. The least negative proximal margin length was 0.1 cm, and the most were 5 cm. The mean margin was 2±1.6 cm. Based on the endoscopic and pathologic findings, the local recurrence at the anastomosis site was 20% in two years of follow-up. The incidence of local tumor recurrence was higher in patients with positive margins versus patients with negative ones (11.4% vs. 8.6%, P=0.007). There was no significant relationship between the negative proximal margin length and the incidence of local anastomotic recurrence.Conclusion: According to our findings, the length of the negative proximal margin has no effect on the rate of local recurrence at the anastomosis site, however it is suggested to reach the negative proximal margin in all tumor stages in total gastrectomy for Siewert II and III gastric cardia tumors.

Abstract Background The etiology of LARS has not been elaborated on clearly. Studies have reported neoadjuvant therapy, low-lying rectal cancers, adjuvant therapy and anastomotic leakage as risk factors for the development of LARS. Anastomotic level has also been proposed as a possible risk factor; However, there have been conflicting results. This study aims to evaluate the role of the level of anastomosis as a potential risk factor for the development of LARS. Method A systematic literature search was conducted on Pubmed, Scopus, Embase, and Web of Science databases using Mesh terms and non-Mesh terms from 2012 to 2023. Original English studies conducted on rectal cancer patients reporting of anastomotic level and LARS status were included in this study. Eligible studies were assessed regarding quality control with Joanna-Briggs Institute (JBI) questionnaires. Results A total of 396 articles were found using the research queries, and after applying selection criteria 4 articles were selected. A sample population of 808 patients were included in this study with a mean age of 61.51 years with male patients consisting 59.28% of the cases. The Mean assessment time was 15.6 months which revealed a mean prevalence of 48.89% for LAR syndrome. Regression analysis revealed significantly increased risk of LAR syndrome development due to low anastomosis level in all 4 studies with odds ratios of 5.336 (95% CI:3.197–8.907), 3.76 (95% CI: 1.34–10.61), 1.145 (95% CI: 1.141–2.149) and 2.11 (95% CI: 1.05–4.27) for low anastomoses and 4.34 (95% CI: 1.05–18.04) for ultralow anastomoses. Conclusions LARS is a long-term complication following surgery, leading to reduced quality of life. Low anastomosis level has been reported as a possible risk factor. All of the studies in this systematic review were associated with an increased risk of LARS development among patients with low anastomosis.

Background: The left coronary artery in the bovines is more developed than the right. Aim: The objective of the study is to describe the bovine coronary system from a morphological point of view, including the morphometry and its distribution. Methods: Arciform suture with 2.0 silk was applied around the sinus orifice and coronary ostium and a number 14 catheter was installed, to perfuse semi-synthetic polyester resin, consisting of a mixture of 85% GP40L palatal with 15% styrene with red color mineral. Results: The average weight of 28 bovine hearts used in our study was 1.534.1 kg. The right coronary artery had a proximal caliber of 5 +/- 0.9 mm. The left coronary artery caliber and length were 9.4 +/- 1.2 mm and 18.3 +/- 4.8 mm, respectively. This artery was divided into two branches in 85.7% of the cases and trifurcated in 14.3%. The paraconal interventricular branch ended more frequently in the apex (46.4%), and its proximal caliber was 6.4 +/- 1.4 mm. The left circumflex branch ended in 82.1% in the subsinusal interventricular sulcus, and its proximal caliber was 5.9 +/- 1.2 mm. The proximal calibers of the paraconal interventricular branch and the left circumflex branch did not present statistically significant differences (p=0.137). The sinoatrial branch presented a dual origin (right and left coronary arteries) in 46.4% of the cases and a single origin from the left coronary artery in 53.6% of the samples. In the evaluated hearts, left coronary dominance was observed in most cases (96.4%). There presence of anastomosis between the branches of the coronary arteries was observed in 57.1% of cases. Conclusion: The presence of a myocardial bridge was found in six hearts (21.4%). In bovines, a high percentage of anastomosis was found, a protective factor in obstruction of the coronary arterial branches. [Open Vet J 2023; 13(8.000): 955-964]

Abstract Background The choice of anastomosis technique after esophagectomy is closely associated with the postoperative complications. Whether circular stapled or linear stapled anastomosis is the optimal technique has not been established. Therefore, we conducted this meta-analysis to show the latest and most comprehensive published assessment of circular stapled anastomosis in comparison with linear stapled anastomosis in postoperative complications. Methods Databases (PubMed, Embase, Web of science, Cochrane Library) were searched for all randomized controlled trials and comparative studies comparing circular stapled anastomosis with linear stapled anastomosis after esophagectomy. The odd ratio and mean difference with 95% confidence interval were calculated. We used the Higgins I² statistics to assess the statistical heterogeneity between studies. Review manager (version 5.4) software was used in this analysis. Results Sixteen studies with 2322 patients were included in our study. The study demonstrated that the use of linear stapled technique after esophagectomy could reduce the risk of both anastomotic leakage (P = 0.0003) and stricture (P

Studies in monozygotic (MZ) twins may help researchers elucidate the complex relationships between genetic and environmental factors on weight loss. We present a world first of MZ twins who have undergone the single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) procedure who have identical weights 3 years post-operatively. Two MZ twin 49-year-old females were assessed preoperatively and were indicated for the SADI-S procedure. They underwent surgery in 2020 by the same surgical team. Three years later post-operatively they had identical weights of 62 kg (and a BMI of 23) and %EWL of 126 and 124% respectively. SADI-S is a novel bariatric procedure for morbid obesity. Studies have found concordant epigenetic patterns in patients who have undergone bariatric surgery as well as MZ twins who have hypocaloric diets. Genetics exert a strong influence in weight management. Surgical management as well as a collaborative multidisciplinary approach is beneficial in supporting long lasting weight loss in bariatric surgery. [ABSTRACT FROM AUTHOR]

Here is presented the first case of internal hernia developing from the space between ureter and muscle fascia after robot-assisted radical cystectomy with uretero-cutaneostomy diversion. An 82-year-old man underwent robot-assisted radical cystectomy with uretero-cutaneostomy diversion for high-grade urothelial carcinoma (pT2). On the Postoperative Day 7, the patient presented abdominal pain and nausea. Abdominal computed tomography showed that a part of the small intestine was protruding between the right ureter and the transverse fascia, and was strangulated, causing an obstruction of the intestine. Patient underwent an emergency laparotomy that revealed prolapse and strangulation of the small intestine through the space between the right ureter and the transversalis fascia. The ischemic intestinal tract and ureter were resected. A new right uretero-cutaneostomy diversion anastomosis with use of ureteral stent single J was created. The man was discharged 28 days after surgery, and his clinical course was uneventful through follow-up. [ABSTRACT FROM AUTHOR]

Ileosigmoidal knotting (ISK) is a rare, possibly fatal cause of intestinal obstruction. ISK is a compound volvulus that is more common in Africa and Asia. ISK is mostly seen in adults, pediatric cases reported in the literature are much rarer. In this report, we present the first reported case of ISK in a pediatric patient from Nepal. An 8-year-old male child presented with symptoms of abdominal pain, vomiting, and obstipation. The abdomen was distended with generalized tenderness. Erect abdominal X-ray showed multiple air-fluid levels. Intraoperatively, gangrenous ileum loops were entangled around the sigmoid, and resection of the gangrenous ileum and sigmoid was performed. An end-to-end colo-colic anastomosis from the descending colon to the remaining sigmoid with a double-loop ileostomy was performed. Pediatric ISK is a rare fatal form of intestinal obstruction that progresses quickly to gangrene. Clinical signs and symptoms are nonspecific, making preoperative diagnosis challenging.

Total enterectomy is an exceedingly rare procedure performed out of necessity due to massive intestinal infarction, trauma, or peritoneal malignancy. This case describes a 47-year-old patient who has successfully undergone the procedure to manage mesenteric ischaemia. Bowel continuity was achieved with a duodenocolonic anastomosis, and the patient has been transitioned to life-long total parental nutrition. This case highlights that carefully selected patients can achieve long-term survival with good quality of life rather than palliation. [ABSTRACT FROM AUTHOR]

Inflammatory fibroid polyps (IFP) are rare benign neoplasms most commonly occurring within the respiratory tract but are rarely also observed in the gastro-intestinal tract. Herein we present the case of a 73-year-old female presenting with ileo-ileal intussusception secondary to IFP. The patient was treated with emergency laparotomy with segmental bowel resection and primary anastomosis. Histopathological analysis of the excised bowel segment initially revealed a low-grade, mural based spindle cell neoplasm with surrounding benign, reactive lymphadenopathy. Immunohistochemical analysis demonstrated that the lesional cells stained positive for Vimentin, Smooth Muscle Actin (SMA), and CD34. On secondary analysis of the specimen, the morphology and immunohistochemical profile of the mass was in keeping with IFP. No invasive malignancy was identified. Such cases have been previously reported under the pseudonym 'the great mimicker' , due to their striking similarity to malignant processes. This case report aims to add to the small body of research reporting such atypical presentations. [ABSTRACT FROM AUTHOR]

Ye, Hongyu and Huang, Weizhao
- Abstract
The reinforcement of the suture lines in acute type A aortic dissection include the treatment of proximal and distal anastomoses. The intima of the proximal site is transected circumferentially, approximately 1.0 cm above the sinotubular junction. The adventitia is folded outwards along the cutting edge of the intima, and the eversion forms an overlap. An autologous pericardial strip is placed inside the aorta as a mattress and secured with 4-0 prolene running sutures to the adventitial eversion overlap to reinforce the proximal cuff without any glue.The distal aortic cuff is trimmed and retained at 1.5 cm longer than the stent graft.The autologous pericardial strip is placed between the aortic intima and the stent graft and secured with 4-0 prolene running sutures to the adventitial eversion overlap to reinforce the distal cuff and completely obliterate the distal false lumen. The modified sandwich technique using adventitial eversion combined with an autologous pericardial strip achieved complete hemostasis at the anastomosis site and effectively obliterated the false lumen of the proximal and distal aorta. The adventitial valgus technique combined with autologous pericardial strip reinforcement can be inexpensive and effective for the surgical treatment of acute type A aortic dissection, especially in patients with fragile aortic wall.

In pediatric colorectal surgery, achieving and visualizing adequate perfusion during complex reconstructive procedures are paramount to ensure postoperative success. However, intraoperative identification of proper perfusion remains a challeng. This review synthesizes findings from the literature spanning from January 2010 to March 2024, sourced from Medline/PubMed, EMBASE, and other databases, to evaluate the role of indocyanine green (ICG) fluorescence imaging in enhancing surgical outcomes. Specifically, it explores the use of ICG in surgeries related to Hirschsprung disease, anorectal malformations, cloacal reconstructions, vaginal agenesis, bladder augmentation, and the construction of antegrade continence channels. Preliminary evidence suggests that ICG fluorescence significantly aids in intraoperative decision-making by improving the visualization of vascular networks and assessing tissue perfusion. Despite the limited number of studies, initial findings indicate that ICG may offer advantages over traditional clinical assessments for intestinal perfusion. Its application has demonstrated a promising safety profile in pediatric patients, underscoring the need for larger, prospective studies to validate these observations, quantify benefits, and further assess its impact on clinical outcomes. The potential of ICG to enhance pediatric colorectal surgery by providing real-time, accurate perfusion data could significantly improve surgical precision and patient recovery.

Background: The intestinal wound healing process is a complex event of three overlapping phases: exudative, proliferative, and remodeling. Although some mechanisms have been extensively described, the intestinal healing process is still not fully understood. There are some similarities but also some differences compared to other tissues. The aim of this systematic review was to summarize all studies with knockout (KO) experimental models in bowel anastomoses, underline any recent knowledge, and clarify further the cellular and molecular mechanisms of the intestinal healing process. A systematic review protocol was performed. Materials and methods: Medline, EMBASE, and Scopus were comprehensively searched. Results: a total of eight studies were included. The silenced genes included interleukin-10, the four-and-one-half LIM domain-containing protein 2 (FHL2), cyclooxygenase-2 (COX-2), annexin A1 (ANXA-1), thrombin-activatable fibrinolysis inhibitor (TAFI), and heparin-binding epidermal growth factor (HB-EGF) gene. Surgically, an end-to-end bowel anastomosis was performed in the majority of the studies. Increased inflammatory cell infiltration in the anastomotic site was found in IL-10-, annexin-A1-, and TAFI-deficient mice compared to controls. COX-1 deficiency showed decreased angiogenesis at the anastomotic site. Administration of prostaglandin E2 in COX-2-deficient mice partially improved anastomotic leak rates, while treatment of ANXA1 KO mice with Ac2-26 nanoparticles reduced colitis activity and increased weight recovery following surgery. Conclusions: our findings provide new insights into improving intestinal wound healing by amplifying the aforementioned genes using appropriate gene therapies. Further research is required to clarify further the cellular and micromolecular mechanisms of intestinal healing.

(1) Background: we conducted this study to evaluate the effect of Kono-S anastomosis on postoperative morbidity after bowel resection for Crohn’s disease. (2) Methods: This study adhered to the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The primary endpoint was the overall complications rate. Secondary outcomes included specific complications analyses, disease recurrence and efficiency endpoints. A systematic literature screening was performed in major electronic scholar databases (Medline, Scopus, Web of Science), from inception to 17 January 2024. Both Random (RE) and Fixed Effects (FE) models were estimated; the reported analysis was based on the Cochran Q test results. (3) Results: Overall, eight studies and 913 patients were included in this meta-analysis. Pooled analyses confirmed that Kono-S was not superior in terms of overall morbidity (OR: 0.69 [0.42, 1.15], p = 0.16). Kono-S displayed a reduced risk for anastomotic leakage (OR: 0.34 [0.16, 0.71], p = 0.004) and reoperation (OR: 0.12 [0.05, 0.27], p < 0.001), and a shortened length of hospital stay (WMD: −0.54 [−0.73, −0.34], p < 0.001). On the contrary, Kono-S results in higher rates of postoperative SSIs (OR: 1.85 [1.02, 3.35], p = 0.04). (4) Conclusions: This study confirms a comparable morbidity, but a lower risk of anastomotic leak and reoperation of Kono-S over conventional anastomoses. Further high quality studies are required to validate these findings.

Ulcerative colitis (UC) is an autoimmune-mediated colitis which can present in varying degrees of severity and increases the individual's risk of developing colon cancer. While first-line treatment for UC is medical management, surgical treatment may be necessary in up to 25-30% of patients. With an increasing armamentarium of biologic therapies, patients are presenting for surgery much later in their course, and careful understanding of the complex interplay of the disease, its management, and the patient's overall health is necessary when considering he appropriate way in which to address their disease surgically. Surgery is generally a total proctocolectomy either with pelvic pouch reconstruction or permanent ileostomy; however, this may need to be spread across multiple procedures given the complexity of the surgery weighed against the overall state of the patient's health. Minimally invasive surgery, employing either laparoscopic, robotic, or transanal laparoscopic approaches, is currently the preferred approach in the elective setting. There is also some emerging evidence that appendectomy may delay the progression of UC in some individuals. Those who treat these patients surgically must also be familiar with the numerous potential pitfalls of surgical intervention and have plans in place for managing problems such as pouchitis, cuffitis, and anastomotic complications.

BackgroundIndocyanine green fluoroscopy has been shown to improve anastomotic leak rates in early phase trials.ObjectiveWe hypothesized that the use of fluoroscopy to ensure anastomotic perfusion may decrease anastomotic leak after low anterior resection.DesignWe performed a 1:1 randomized controlled parallel study. Recruitment of 450 to 1000 patients was planned over 2 years.SettingsThis was a multicenter trial.PatientsIncluded patients were those undergoing resection defined as anastomosis within 10 cm of the anal verge.InterventionPatients underwent standard evaluation of tissue perfusion versus standard in conjunction with perfusion evaluation using indocyanine green fluoroscopy.Main outcome measuresPrimary outcome was anastomotic leak, with secondary outcomes of perfusion assessment and the rate of postoperative abscess requiring intervention.ResultsThis study was concluded early because of decreasing accrual rates. A total of 25 centers recruited 347 patients, of whom 178 were randomly assigned to perfusion and 169 to standard. The groups had comparable tumor-specific and patient-specific demographics. Neoadjuvant chemoradiation was performed in 63.5% of perfusion and 65.7% of standard (p > 0.05). Mean level of anastomosis was 5.2 ± 3.1 cm in perfusion compared with 5.2 ± 3.3 cm in standard (p > 0.05). Sufficient visualization of perfusion was reported in 95.4% of patients in the perfusion group. Postoperative abscess requiring surgical management was reported in 5.7% of perfusion and 4.2% of standard (p = 0.75). Anastomotic leak was reported in 9.0% of perfusion compared with 9.6% of standard (p = 0.37). On multivariate regression analysis, there was no difference in anastomotic leak rates between perfusion and standard (OR = 0.845 (95% CI, 0.375-1.905); p = 0.34).LimitationsThe predetermined sample size to adequately reduce the risk of type II error was not achieved.ConclusionsSuccessful visualization of perfusion can be achieved with indocyanine green fluoroscopy. However, no difference in anastomotic leak rates was observed between patients who underwent perfusion assessment versus standard surgical technique. In experienced hands, the addition of routine indocyanine green fluoroscopy to standard practice adds no evident clinical benefit.

Se planificó el reclutamiento de 450-1000 pacientes durante 2 años.AMBITO:Multicéntrico.PACIENTES:Pacientes sometidos a resección definida como una anastomosis dentro de los 10cm del margen anal.INTERVENCIÓN:Pacientes que se sometieron a la evaluación estándar de la irrigación tisular contra la estándar en conjunto con la valoración de la irrigación mediante fluoroscopia con verde indocianina.PRINCIPALES VARIABLES EVALUADAS:El principal resultado fue la fuga anastomótica, y los resultados secundarios fueron la evaluación de la perfusión y la tasa de absceso posoperatorio que requirió intervención.RESULTADOS:Este estudio se cerró anticipadamente debido a la disminución de las tasas de acumulación. Un total de 25 centros reclutaron a 347 pacientes, de los cuales 178 fueron, de manera aleatoria, asignados a perfusión y 169 a estándar. Los grupos tenían datos demográficos específicos del tumor y del paciente similares. Recibieron quimio-radioterapia neoadyuvante el 63,5% de la perfusión y el 65,7% del estándar (p> 0,05). La anastomosis estuvo en un nivel promedio de 5,2 + 3,1 cm en perfusión en comparación con 5,2 + 3,3 cm en estándar (p> 0,05). Se reportó una visualización suficiente de la perfusión en el 95,4% de los pacientes del grupo de perfusión. El absceso posoperatorio que requirió tratamiento quirúrgico fue de 5,7% de los perfusion y en el 4,2% del estándar (p = 0,75). Se informó fuga anastomótica en el 9,0% de la perfusión en comparación con el 9,6% del estándar (p = 0,37). En el análisis de regresión multivariante, no hubo diferencias en las tasas de fuga anastomótica entre la perfusión y el estándar (OR 0,845; IC del 95% (0,375; 1,905); p = 0,34).LIMITACIONES:No se logró el tamaño de muestra predeterminado para reducir satisfactoriamente el riesgo de error tipo II.CONCLUSIÓN:Se puede obtener una visualización adecuada de la perfusión con ICG-F. Sin embargo, no se observaron diferencias en las tasas de fuga anastomótica entre los pacientes que se sometieron a evaluación de la perfusión versus la técnica quirúrgica estándar. En manos expertas, agregar ICG-F a la rutina de la práctica estándar no agrega ningún beneficio clínico evidente. Consulte Video Resumen en http://links.lww.com/DCR/B560.

ObjectiveTo determine whether ejaculatory dysfunction (EjD) and post-void dribbling (PVD) after urethroplasty are associated, providing evidence for a common etiology.MethodsWe reviewed a prospectively maintained database for first-time, anterior urethroplasties. One item from the Male Sexual Health Questionnaire (MSHQ) assessed EjD: "How would you rate the strength or force of your ejaculation". One item from the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM) assessed PVD: "How often have you had slight wetting of your pants after you had finished urinating?". The frequency of symptoms was compared after penile vs. bulbar repairs, and anastomotic versus augmentation bulbar repairs. Associations were assessed with chi-square.ResultsA total of 728 men were included. Overall, postoperative EjD and PVD were common; 67% and 66%, respectively.

Stem rot symptoms were observed in Gondre (Cirsium setidens) plants growing in a vinyl greenhouse in Taebaek, Korea during a disease survey in June 2022. The plants presented with dark brown to black rot on the stems at or above the soil line. Severely diseased plants displayed wilt and blight. Disease incidence among these plants ranged from 1 to 5%. Three isolates of Rhizoctonia sp. were obtained from the stem lesions of diseased plants. All isolates were identified as Rhizoctonia solani AG-2-2(IV) based on the morphological and cultural characteristics, results of the anastomosis test, and phylogenetic analysis. The pathogenicity of the isolates to Gondre plants was confirmed using an artificial inoculation test. The lesions induced by the inoculation test were similar to those observed in the investigated vinyl greenhouse. Here, we report a case of R. solani AG-2-2(IV) causing stem rot in Gondre.

Technological advancements in minimally invasive surgery have led to significant improvements in patient outcomes. One such technology is surgical stapling, which has evolved into a key component of many operating rooms by facilitating ease and efficacy in resection and repair of diseased or otherwise compromised tissue. Despite such advancements, adverse post-operative outcomes such as anastomotic leak remain a persistent problem in surgical stapling and its correlates (i.e., hand-sewing), most notably in low colorectal or coloanal procedures. Many factors may drive anastomotic leaks, including tissue perfusion, microbiome composition, and patient factors such as pre-existing disease. Surgical intervention induces complex acute and chronic changes to the mechanical environment of the tissue; however, roles of mechanical forces in post-operative healing remain poorly characterized. It is well known that cells sense and respond to their local mechanical environment and that dysfunction of this “mechanosensing” phenomenon contributes to a myriad of diseases. Mechanosensing has been investigated in wound healing contexts such as dermal incisional and excisional wounds and development of pressure ulcers; however, reports investigating roles of mechanical forces in adverse post-operative gastrointestinal wound healing are lacking. To understand this relationship well, it is critical to understand: 1) the intraoperative material responses of tissue to surgical intervention, and 2) the post-operative mechanobiological response of the tissue to surgically imposed forces. In this review, we summarize the state of the field in each of these contexts while highlighting areas of opportunity for discovery and innovation which can positively impact patient outcomes in minimally invasive surgery.

Purpose Regular practice, quality clinical exposure, and academic discussion are essential in any surgical specialty training. This study discusses and validates the option of using a fresh “chicken quarter” model with a measurable scoring system, as a standard training regimen in microvascular surgery. This can be a very effective, economical, and easily accessible model for residents. Materials and Methods This study was conducted in the Department of Plastic surgery, from October 2020 to May 2021. Twenty-four fresh “chicken quarter” specimens were dissected and the ischial arteries and femoral veins' external diameter (ED) were measured. The microsurgical skills of the trainee were assessed in 6 months intervals using the Objective Structured Assessment of Technical Skills Scale (OSATS) as well as the time taken for anastomosis. All the data were analyzed using SPSS (statistical package for social sciences) version 21. Results A task-specific score value of 50% on October 2020 improved to 85.7% by May 2021. This was found to be statistically significant (p = 0.043). The mean ED of the ischial artery and femoral vein was 2.07 and 2.26 mm, respectively. The mean width of the vein measured at the lower one-third of the tibia was 2.08 mm. A greater than 50% reduction in anastomosis time was observed after a period of 6 months. Conclusion In our minimal experience, the “chicken quarter model” with OSATS scoring system seems to be effective, economical, very affordable, and easily accessible microsurgery training model for the residents. Our study is done only as a pilot project due to limited resources and we have the plan to introduce it as a proper training method in the near future with more residents.

Background: Hand-sewn intestinal resection and anastomosis is commonly performed in veterinary medicine. The outcome of hand-sewn side-to-side anastomosis technique has never been described and compared to other techniques in dogs and cats. Aim: The aim of the study is to describe the side-to-side hand-sewn anastomosis technique in small animals and to compare it with the end-to-end technique. Methods: A retrospective evaluation of the clinical records of dogs and cats that underwent enterectomy between 2000 and 2020 and were treated with side-to-side or end-to-end anastomosis was performed. Results: Of the 52 dogs and 16 cats included in the study, 19 dogs and 6 cats received a side-to-side anastomosis, and the remaining received an end-to-end anastomosis. No intraoperative complication was reported. Short-term complication rates were comparable and mortality rates in end-to-end anastomosis group were higher, while stenosis was a frequent complication of side-to-side anastomosis and never reported following end-to-end anastomosis. Conclusion: End-to-end technique remains the gold standard for hand-sewn intestinal anastomosis in small animals, but side-to-side anastomosis can be considered for selected cases with acceptable morbidity and mortality rates.

Abstract Background The surgical procedure for laparoscopic right colectomy (LRC) is not standardized. Some published studies show the superiority of ileocolic anastomosis (IIA), but the evidence so far is insufficient. This study aimed to investigate the potential advantages in postoperative recovery and safety of IIA in LRC. Methods A total of 114 patients who underwent LRC with IIA (n = 58) or extracorporeal ileocolic anastomosis (EIA, n = 56) between January 2019 and September 2021 were enrolled. We collected certain factors as clinical features, intraoperative characteristics, oncological outcomes, postoperative recovery, and short-term outcomes. Our primary outcome was time to gastrointestinal (GI) function recovery. Secondary outcomes were postoperative complications within 30 days, postoperative pain, and length of hospital stay. Results Faster GI recovery and less postoperative pain were observed in patients with IIA compared to EIA [time to first flatus: (2.4 ± 0.7) vs (2.8 ± 1.0) days, p

Abstract Background Clinical instructional strategies and the climate in which teaching and learning take place have a significant impact on the quality of dental education. Therefore, this study aimed to evaluate the impact of early microsurgery training on the skills of dental intern students who are planning to join an oral and maxillofacial surgical field (DIS) as compared with junior residents within an oral and maxillofacial surgery department who had no microsurgery experience (JR). Methods A total of 100 trainees, 70 were DIS, while the other 30 were JR. The average age was 23.87 ± 2.05 years for DIS group and 31.05 ± 3.06 for JR group. All trainees attended a microsurgical course (theoretical and practical parts) for seven days within a Microvascular Laboratory for Research and Education of a university-affiliated tertiary hospital. Two blinded examiners had assessed the performance of trainees independently using a specific scoring system. The independent sample t-test was used to compare the effect of microsurgery training between DIS and JR groups. The significance level was set at 0.05.

Abstract Background Anastomotic leakage has been reported to occur when the load on the anastomotic site exceeds the resistance created by sutures, staples, and early scars. It may be possible to avoid anastomotic leakage by covering and reinforcing the anastomotic site with a biocompatible material. The aim of this study was to evaluate the safety and feasibility of a novel external reinforcement device for gastrointestinal anastomosis in an experimental model. Methods A single pig was used in this non-survival study, and end-to-end anastomoses were created in six small bowel loops by a single-stapling technique using a circular stapler. Three of the six anastomoses were covered with a novel external reinforcement device. Air was injected, a pressure test of each anastomosis was performed, and the bursting pressure was measured. Results Reinforcement of the anastomotic site with the device was successfully performed in all anastomoses. The bursting pressure was 76.1 ± 5.7 mmHg in the control group, and 126.8 ± 6.8 mmHg in the device group, respectively. The bursting pressure in the device group was significantly higher than that in the control group (p = 0.0006). Conclusions The novel external reinforcement device was safe and feasible for reinforcing the anastomoses in the experimental model.

Objectives: Preventing anastomotic complications during rectal cancer surgery is important. Compared with a manual circular stapler, a powered circular stapler is expected to reduce undesirable tension during anastomosis. However, whether a powered circular stapler can reduce anastomotic complications during robotic low anterior resection (Ro-LAR) remains unclear. We aimed to investigate whether the use of a powered circular stapler contributes to safe anastomosis in Ro-LAR. Methods: A total of 271 patients who underwent Ro-LAR for rectal cancer between April 2019 and April 2022 were included. Depending on the type of device employed, patients were divided into a powered circular stapler group (PCSG) and a manual circular stapler group (MCSG). Clinicopathological features and surgical outcomes were compared between the two groups. Results: There were no differences in clinicopathological characteristics and surgical outcomes, except for anastomotic outcomes, between the two groups. Patients with positive air leak tests were significantly more in the MCSG (p=0.026; PCSG, 1.5%; MCSG, 8.0%). Frequencies of anastomotic leakage (p=0.486; PCSG, 6.1%; MCSG, 8.9%) and anastomotic bleeding (p=1.000; PCSG, 0.7%; MCSG, 0.8%) were similar between the two groups. Multivariate analysis showed that the use of a powered circular stapler significantly increased the negative leak tests (p=0.020, odds ratio 6.74, 95% confidence interval 1.35-33.56). Conclusions: Use of a powered circular stapler in Ro-LAR for rectal cancer was significantly associated with a negative air leak test, suggesting that it contributes to stable and safe anastomosis.

Abstract Background Arteriovenous fistula (AVF) is the gold standard vascular access for effective hemodialysis. There is a growing interest in AVF creations performed by nephrologists to help reduce vascular surgeons’ workload and enhance the timely treatment of patients with end-stage renal disease (ESRD). However, little is known about the feasibility and effectiveness of this approach in the low-resource settings. We examined the AVF surgical success and failure rates and associated predictors as well as early complications of AVF creations by a trained nephrologist with supports from vascular surgeons in Vietnam. Methods A prospective cohort study was conducted on all adult ESRD patients at the Hemodialysis Department of Thong Nhat Hospital between April 2018 and October 2020. Information on demographic characteristics, comorbidities, and AVF creations was collected using a standardized questionnaire. All patients were followed up until 18 weeks post-surgery. Results Among 100 patients with a mean age of 61.22 ± 17.11 years old, male accounted for 54%. Common causes of ESRD included hypertension (57%) and diabetes (32%). Just more than half (52%) of them reported having an AVF creation prior to ESRD. The successful first-time AVF creation rate was 98% (13/99, 95%CI: 8.74–21.18%). The primary and secondary AVF failure rates were 13.13% (13/99, 95%CI: 8.74–21.18%) and 16.87% (14/83, 95%CI: 10.32–26.25%), respectively. Early complications included bleeding (1%) and early thrombosis of the anastomosis (2%). There was a statistically significant association between age and primary AVF failure (P = 0.005) and between operation time and secondary AVF failure (P = 0.038). Conclusions AVF creations performed by well-trained and skilled interventional nephrologists with supports from vascular surgeons can result in favorable short- and long-term outcomes. It is important to follow up older patients and those with a long operation time to detect AVF failures. A standardized AVF creation training program and practice for nephrologists is needed to increase successful rates.

Abstract For surgeries involving vessel anastomosis, it is critical to ensure fluent blood flow and to monitor the occurrence of vascular complications. However, the current clinical methods are ineffective in achieving direct, continuous, and accurate monitoring. At present, implantable sensors are widely used and explored in various biomedical applications, including cardiovascular disease, neurological disorders, cancer treatment, and health monitoring. They can be easily placed during surgical procedures and offer irreplaceable advantages including directness, continuity, and higher accuracy of monitoring. Based on this, the types of implantable sensors for vascular monitoring are reviewed, and some preclinical research advances which are expected to provide promising methods for post‐surgical vascular complications are discussed. In the end, the future perspectives of the research of implantable sensors for post‐surgical monitoring are put forward. It is believed that implantable sensors hold great promise in clinical translation, providing physicians with more accurate, continuous, and real‐time monitoring results, helping to improve surgical success and patient outcomes.

In specialized centers minimally invasive surgery has become established as the standard of care for esophageal and gastric surgery. Offering equal oncological outcome, patients benefit with respect to lower postoperative pain and complication rates. The creation of the anastomosis during minimally invasive surgery remains a critical step and the complications are decisive for the immediate postoperative course. So far no clear consensus exists in the literature regarding the recommended techniques for placement of an anastomosis after resections in the upper gastrointestinal tract. This article summarizes and compares the various established anastomotic techniques used in minimally invasive esophageal and gastric surgery. [ABSTRACT FROM AUTHOR]

This case report describes the surgical repair of a total traumatic rupture of the membranous urethra in a 5 years old, mixed-breed male canine patient who was hit three days earlier by a car. In this procedure, the technique described by Fossum (2019) was used with modifications made by the surgical experience of the authors, where a prostatic fixation point was used, allowing to reduce the tension forces exerted by the bladder and the size of the defect. In cases of abdominal trauma, comorbidities are associated with a worse prognosis, in this case, the uroabdomen was treated immediately. The patient remains in the postoperative period for 4 weeks and 14 months later presents a perfect function of the lower urinary tract with normal urine flow, considering that the technique was successful. Systemic antibiotics and anti-inflammatories were administered, and the wound was completely closed three weeks later. The objective of this work is to present a minimally invasive technique without intraoperative complications in which the conservative procedure is modified, generating a successful result without the need for a pubic osteotomy which, in addition to being highly invasive with the tissues, is quite painful for the patient.

- Abstract
There is ongoing debate whether the type of anastomosis following intestinal resection for Crohn's disease (CD) can impact on complications and postoperative recurrence. The aim of the present study is to describe the outcomes of side-to-side (S–S) vs end-to-end (E–E) anastomosis after ileocecal resection for CD. A retrospective comparative study was conducted in consecutive CD patients who underwent primary ileocecal resection between 2005 and 2013. All patients underwent colonoscopy 6 months postoperatively to assess endoscopic recurrence, defined as Rutgeerts' score (RS) ≥ i2. Surgical recurrence implied reoperation due to CD activity at the anastomotic site. Modified surgical recurrence was defined as the need for reoperation or balloon-dilation. Perioperative factors related to recurrence were evaluated. Of the 127 patients included, 51 (40.2%) received an E–E anastomosis. Median follow-up was longer in the E–E group (8.62 vs 13.68 years). Apart from the microscopic resection margins, patient, disease and surgical characteristics were similar between both groups. Anastomotic complications were comparable (S–S 5.3% vs E–E 5.8%, p = 1.00)0. Postoperatively, biologicals were used in 55.3% and 62.7% (p = 0.47) in S–S and E–E patients, respectively. Endoscopic recurrence did not differ between S–S and E–E patients (78.9 vs 72.9%, p = 0.37), with no significant difference in RS values between both groups (p = 0.87). Throughout follow-up, a higher surgical (p = 0.04) and modified surgical recurrence (p = 0.002) rate was observed in the E–E anastomosis group. Type of anastomosis was an independent risk factor for modified surgical recurrence. The type of anastomosis did not influence endoscopic recurrence and immediate postoperative disease complications. However, the wide diameter and the morphologic characteristic of the stapled S–S anastomosis resulted in a significant reduced risk for surgical and endoscopic reintervention on the long term.

Background: The etiology of LARS has not been elaborated on clearly. Studies have reported neoadjuvant therapy, low-lying rectal cancers, adjuvant therapy and anastomotic leakage as risk factors for the development of LARS. Anastomotic level has also been proposed as a possible risk factor; However, there have been conflicting results. This study aims to evaluate the role of the level of anastomosis as a potential risk factor for the development of LARS. Method: A systematic literature search was conducted on Pubmed, Scopus, Embase, and Web of Science databases using Mesh terms and non-Mesh terms from 2012 to 2023. Original English studies conducted on rectal cancer patients reporting of anastomotic level and LARS status were included in this study. Eligible studies were assessed regarding quality control with Joanna-Briggs Institute (JBI) questionnaires. Results: A total of 396 articles were found using the research queries, and after applying selection criteria 4 articles were selected. A sample population of 808 patients were included in this study with a mean age of 61.51 years with male patients consisting 59.28% of the cases. The Mean assessment time was 15.6 months which revealed a mean prevalence of 48.89% for LAR syndrome. Regression analysis revealed significantly increased risk of LAR syndrome development due to low anastomosis level in all 4 studies with odds ratios of 5.336 (95% CI:3.197–8.907), 3.76 (95% CI: 1.34–10.61), 1.145 (95% CI: 1.141–2.149) and 2.11 (95% CI: 1.05–4.27) for low anastomoses and 4.34 (95% CI: 1.05–18.04) for ultralow anastomoses. Conclusions: LARS is a long-term complication following surgery, leading to reduced quality of life. Low anastomosis level has been reported as a possible risk factor. All of the studies in this systematic review were associated with an increased risk of LARS development among patients with low anastomosis. [ABSTRACT FROM AUTHOR]

Background: Severe thoracic deformity caused by scoliosis often hampers lung transplantation (LTx) due to its underlying restrictive ventilatory dysfunction. Postoperative stenosis of the reconstructed bronchus due to spinal compression is also a complication after LTx in patients with scoliosis. Previous reports on LTx with scoliosis and its outcomes have not discussed the technical aspect of bronchial anastomosis. This report describes a case in which bronchial stenosis was avoided by modifying the angle of the right bronchial anastomosis. Case presentation: A 26-year-old woman with atrial septal defect (ASD), pulmonary hypertension, Eisenmenger's syndrome, and severe right scoliosis underwent bilateral living-related lobar LTx with her parents as donors followed by ASD closure. Left pneumonectomy and anastomosis preceded. On the right side, after pneumonectomy, the recipient's right main bronchus was trimmed to rotate the bronchial anastomosis clockwise by 45°. This resulted in clockwise rotation of the graft (the lower lobe of the mother's right lung), making axes of the graft and deformed vertebrae parallel. Postoperative bronchoscopy 2 months after surgery showed no evidence of compression or stenosis of the basal bronchial branch. Conclusion: By obliquely trimming the recipient's right main bronchus to make the angle of the pulmonary graft and deformed thorax parallel, postoperative bronchial stenosis owing to severe scoliosis was successfully avoided.

In microvascular head and neck reconstruction, various factors such as diabetes, alcohol consumption, and preoperative radiation hold a risk for flap loss. The primary objective of this study was to examine the vessel morphology of both recipient and donor vessels and to identify predictors for changes in the diameters of H.E.-stained specimens associated with flap loss in a prospective setting. Artery and vein samples (N = 191) were collected from patients (N = 100), with sampling from the recipient vessels in the neck area and the donor vessels prior to anastomosis. External vessel diameter transverse (ED), inner vessel diameter transverse (ID), thickness vessel intima (TI), thickness vessel media (TM), thickness vessel wall (TVW), and intima-media ratio (IMR) for the recipient (R) and transplant site (T) in arteries (A) and veins (V) were evaluated using H.E. staining. Flap loss (3%) was associated with increased ARED (p = 0.004) and ARID (p = 0.004). Preoperative radiotherapy led to a significant reduction in the outer diameter of the recipient vein in the neck (p = 0.018). Alcohol consumption (p = 0.05), previous thrombosis (p = 0.007), and diabetes (p = 0.002) were associated with an increase in the total thickness of venous recipient veins in the neck. Diabetes was also found to be associated with dilation of the venous media in the neck vessels (p = 0.007). The presence of cardiovascular disease (CVD) was associated with reduced intimal thickness (p = 0.016) and increased total venous vessel wall thickness (p = 0.017) at the transplant site. Revision surgeries were linked to increased internal and external diameters of the graft artery (p = 0.04 and p = 0.003, respectively), while patients with flap loss showed significantly increased artery diameters (p = 0.004). At the transplant site, alcohol influenced the enlargement of arm artery diameters (p = 0.03) and the intima–media ratio in the radial forearm flap (p = 0.013). In the anterolateral thigh, CVD significantly increased the intimal thickness and the intima–media ratio of the graft artery (p = 0.01 and p = 0.02, respectively). Patients with myocardial infarction displayed increased thickness in the A. thyroidea and artery media (p = 0.003). Facial arteries exhibited larger total vessel diameters in patients with CVD (p = 0.03), while facial arteries in patients with previous thrombosis had larger diameters and thicker media (p = 0.01). The presence of diabetes was associated with a reduced intima–media ratio (p < 0.001). Although the presence of diabetes, irradiation, and cardiovascular disease causes changes in vessel thickness in connecting vessels, these alterations did not adversely affect the overall success of the flap.

Background: The choice of anastomosis technique after esophagectomy is closely associated with the postoperative complications. Whether circular stapled or linear stapled anastomosis is the optimal technique has not been established. Therefore, we conducted this meta-analysis to show the latest and most comprehensive published assessment of circular stapled anastomosis in comparison with linear stapled anastomosis in postoperative complications. Methods: Databases (PubMed, Embase, Web of science, Cochrane Library) were searched for all randomized controlled trials and comparative studies comparing circular stapled anastomosis with linear stapled anastomosis after esophagectomy. The odd ratio and mean difference with 95% confidence interval were calculated. We used the Higgins I² statistics to assess the statistical heterogeneity between studies. Review manager (version 5.4) software was used in this analysis. Results: Sixteen studies with 2322 patients were included in our study. The study demonstrated that the use of linear stapled technique after esophagectomy could reduce the risk of both anastomotic leakage (P = 0.0003) and stricture (P < 0.00001) compared with circular stapled technique. Stratification by anastomotic site showed that no matter what kind of anastomotic site (cervical or thoracic anastomosis) was used, linear stapled anastomosis could effectively reduce the anastomotic stricture in comparison with circular stapled anastomosis. Moreover, linear stapled anastomosis could decrease the risk of thoracic anastomotic leakage. There were no significant differences between circle stapled anastomosis and linear stapled anastomosis in reflux esophagitis (P = 0.17), pneumonia (P = 0.91), operation time (P = 0.41) and hospital stay (P = 0.38). Conclusions: The study suggested that linear stapled anastomosis could be considered to be an optimal treatment associated with a reduced risk of anastomotic leakage and stricture in comparison with circular stapled anastomosis.

Background: We performed pull-through hand-sewn coloanal anastomosis immediately after sphincter-preserving ultralow anterior resection (ULAR) [pull-through ultra (PTU)] to avoid permanent stoma and reduce postoperative complications of lower rectal tumors. This study aimed to compare the clinical outcomes of PTU versus non-PTU (stapled or hand-sewn coloanal anastomosis with diverting stoma) after sphincter-preserving ULAR for lower rectal tumors. Methods: This retrospective cohort study analyzed prospectively maintained data from 100 consecutive patients who underwent PTU (n = 29) or non-PTU (n = 71) after sphincter-preserving ULAR for rectal tumors between January 2011 and March 2023. In PTU, hand-sewn coloanal anastomosis was immediately performed using 16 stitches of 4–0 monofilament suture during primary surgery. The clinical outcomes were assessed. The primary outcomes were rates of permanent stomas and overall postoperative complications. Results: The PTU group was significantly less likely to require a permanent stoma than the non-PTU group (P < 0.01). None of the patients in the PTU group required permanent stoma and the rate of overall complications was significantly lower in the PTU group (P = 0.01). The median operative time was comparable between the two groups (P = 0.33) but the median operative time during the second stage was significantly shorter in the PTU group (P < 0.01). The rates of anastomotic leakage and complications of Clavien–Dindo grade III were comparable between the two groups. Diverting ileostomy was performed in two patients with an anastomotic leak in the PTU group. The PTU group was significantly less likely to require a diverting ileostomy than those in the non-PTU group (P < 0.01). The composite length of hospital stay was significantly shorter in the PTU group (P < 0.01). Conclusions: PTU via immediate coloanal anastomosis for lower rectal tumors is a safe alternative to the current sphincter-preserving ULAR with diverting ileostomy for patients who wish to avoid a stoma.

Anastomotic stricture/stenosis is an alarming complication developing after colorectal surgery. The purpose of this study was to compare the severity of anastomotic stricture/stenosis developing after transanal total mesorectal excision to that developing after laparoscopic total mesorectal excision. This research included patients with confirmed rectal adenocarcinoma who underwent transanal total mesorectal excision or laparoscopic total mesorectal excision with stapled anastomosis at Shengjing Hospital of China Medical University from March 2018 to June 2021. For comparison of anastomotic stricture/stenosis at 1, 3, and 6 months after surgery, a special stricture/stenosis grading system was adopted. A total of 41 patients (21 who underwent transanal total mesorectal excision and 20 who underwent laparoscopic total mesorectal excision, all with defunctioning stoma) received neoadjuvant radiotherapy, and 172 patients (86 patients underwent transanal total mesorectal excision, and the remaining 86 underwent laparoscopic total mesorectal excision, with 55 of the former and 49 of the latter receiving defunctioning stoma) did not receive radiotherapy which were enrolled in the study. The severity of the stricture was graded at 1, 3, and 6 months after surgery. For patients who did not receive radiotherapy, anastomotic stricture/stenosis developing after transanal total mesorectal excision was more severe than that developing after laparoscopic total mesorectal excision during the follow-up period (all p < 0.05), and such differences were always significant in cases with a defunctioning stoma (all p < 0.05) but not obvious in cases without a defunctioning stoma at 1 and 3 months after surgery (all p > 0.05). In case of patients who received radiotherapy, no difference was noted between the transanal total mesorectal excision and laparoscopic total mesorectal excision groups in terms of the degrees of anastomotic stricture/stenosis (all p > 0.05), and compared with patients who did not receive radiotherapy, more severe degrees of anastomotic stricture/stenosis were observed (all p < 0.05). During the short-term follow-up, the severity of anastomotic stricture/stenosis was higher after transanal total mesorectal excision with stapled anastomosis than after laparoscopic total mesorectal excision and mainly occurred in patients with a defunctioning stoma and those who did not receive radiotherapy. There was no differences between the two groups of patients who received radiotherapy in terms of severity. [ABSTRACT FROM AUTHOR]
