Internal Supravesical Hernia Revealed by Small Bowel Obstruction

Small bowel obstruction secondary to ingested fish bone is an exceedingly rare occurrence, particularly among the elderly, accounting for less than 1% of cases necessitating surgical intervention. This article reports a case of an 84-year-old male who presented with acute abdominal pain and bilious vomiting for seven days after accidentally swallowing a fish bone. Computed Tomography (CT) of the abdomen and pelvis indicated sub-acute bowel obstruction, revealing a linear foreign body in the jejunum with a focal collection. An emergency exploratory laparotomy uncovered a pocket of pus containing the fish bone in the mesentery of the jejunum, with evidence of perforation at approximately 150 cm distal to the duodenojejunal flexure.

EGS SO22 - When What Is Left Is Not Right

Abstract Background Aims We present a case of small bowel obstruction in a massive inguinoscrotal hernia, with loss of abdominal domain, treated successfully by emergency surgery. The chronicity of the condition resulted in a large pendulous pelvic stomach, with the Duodeno jejunal flexure within the hernia and constricted by the hernial ring. Method The first contact with surgical team was as emergency, since initial referral to surgical outpatients was deferred by the patient, due to his embarrassment. After initial attempts to decompress the stomach through nasogastric tube and with nutritional support with parenteral nutrition, the patient was counselled for surgery. Informed consent was taken for right orchidectomy, possibility of open abdomen with delayed reconstruction, stoma, respiratory compromise, multiorgan failure and death.Prior to intervention, Intensive Therapy unit was consulted for admission following surgery, with plans to use Botox in the abdominal wall, to improve compliance, in case of abdominal compartment syndrome or respiratory failure. Results Through an inguinoscrotal incision, the inguinal canal was opened and the cord structures were transfixed and divided. The internal ring was divided laterally to allow gradual compression and replacement of the hernia intraabdominally. Over 8 litres of fluid was removed from Nasogastric aspirate. Lymphoedema in the scrotum made the laterality of the testis seen in the operative field ambiguous. The hernia was repaired with Bassini repair of the muscles, followed by polypropelene mesh. Following surgery, patient was discharged home with no immediate complications. Histology of the sac and Tunica Vaginalis revealed an atrophic right testis. Conclusion Distorted anatomy from chronicity of common surgical pathology may present challenge to even experienced surgeons. Unusual presentation of common pathology requires thinking outside the box. Since the lymphoedema in the scrotal hernial sac made the laterality of the testis unclear, an informed decision was taken not to remove the single testis seen in the operative field. The histology confirmed that this was the right decision, since the atrophic right testis was included in the operative specimen. Post operative imaging confirmed what was left, was the left testis.

BN SO62 - Laparoscopic technique for right sided paraduodenal hernia repair: A clinical study and surgical insights

Abstract Background Paraduodenal hernias can present significant diagnostic and therapeutic challenges, with up to 50% potentially leading to bowel obstruction. A minimally invasive approach to repairing these defects offers reduced morbidity and quicker recovery. This report highlights the feasibility and safety of laparoscopic repair of a right-sided paraduodenal hernia. Method A 19-year-old female presented with persistent postprandial bilious vomiting and a long history of forceful regurgitation 10-30 minutes after eating. The preoperative evaluation, surgical technique and operative outcomes are detailed. Results Preoperative evaluation included magnetic resonance imaging, computed tomography and a barium swallow, revealing an incidental finding of the duodenojejunal flexure and most jejunal loops on the right side of the abdomen. A right paraduodenal hernia was diagnosed during laparoscopy. After delineating and reducing the hernia laparoscopically, the sac was obliterated by opening up the posterior aspect over the inferior vena cava. The repair was completed by suturing the hernia orifice and plicating the duodenum. The patient's symptoms resolved postoperatively, with no intraoperative or immediate postoperative adverse outcomes reported. Scheduled outpatient follow-up showed satisfactory resolution of symptoms. Conclusion The laparoscopic repair of the right paraduodenal hernia was successfully performed, leading to the resolution of the patient's symptoms. This case underscores the importance of considering laparoscopic approaches for managing complex and rare hernias, especially when cross-sectional imaging modalities do not clearly identify the cause of symptoms. The laparoscopic technique offers significant advantages, including reduced pain and faster recovery.

VS 01 - BN Chronic loop gastrojejunostomy volvulus masquerading as a Crohn’s stricture

Abstract Background A video presentation of a case of chronic loop gastrojejunostomy volvulus masquerading as a Crohn's stricture. Method 61 year old female with a previous loop gastrojejunostomy and subsequent ileocaecal resection for Crohn's related pyloric stenosis and terminal ileal stricture. Acute worsening of post-prandial pain and vomiting 5 years later, re-investigation revealed a stenosed gastrojejunostomy thought to be Crohn's related. Results Intraoperative volvulus of the gastrojejunostomy was demonstrated related to traction forces resulting in the migration of the duodeno-jejunal flexure to the right of midline. The gastrojejunostomy was revised to a Roux-en-Y configuration with relief of mechanical obstruction. Conclusion An ileocaecal resection may create unexpected traction forces

Intestinal malrotation in newborns and infants: comparative possibilities of ultrasound and radiologic methods of investigation

BACKGROUND: Intestinal malrotation is a congenital pathology that results from abnormal fixation and rotation of the midgut during fetal development. This pathological condition is most often diagnosed during the first month of life and is often manifested by the presence of regurgitation, restlessness, vomiting with an admixture of bile, low weight gain. The narrow root of the mesentery facilitates the formation of midgut ingestion, which can lead to ischemia and necrosis and requires urgent surgical intervention. Ultrasound and radiologic examination with contrast are currently used to diagnose malrotation. AIM: To improve the diagnosis of intestinal malrotation in newborns and infants by carrying out a comparative analysis of the capabilities of radiologic and ultrasound methods of investigation when they are used in combination. MATERIALS AND METHODS: Data from 112 patients aged from 1 day from birth to 3 months 26 days between 2016 and 2024 with ultrasound signs of malrotation detected by microconvex and linear transducers were analyzed. 50 children were further followed up with this provisional or final diagnosis. Contrast agent passages and irrigographs were performed on an AXIOM Luminos DRF (Siemens), with 1 to 15 radiographs and up to 8 X-ray examination series obtained. RESULTS: The most common ultrasound sign of malrotation was atypical location of mesenteric vessels, and the most common radiologic sign was left-sided location of the colon and high standing of the cecum. Assessment of the location of the duodenojejunal junction was complicated in most cases. Surgery was performed in 17 children, one of them for suspected intestinal obstruction, and a ring-shaped pancreas was found in 4 patients. The diagnosis of malrotation was made in 40 children out of 50, in 4 cases this was discordant with the radiologic findings. Concomitant abnormal location of internal organs was detected in 12 patients. CONCLUSION: Screening ultrasound examination of all newborns should be considered as the pathology may be asymptomatic. It is important to include suspicion of malrotation in the diagnosis because of the possible manifestation of the pathology at a later age. It is currently not possible to completely abandon radiologic examination with contrast in the diagnosis of malrotation.

Tackling catabolic state in high output stoma cases: our experience with enriched stoma content refeeding

Background: Patients who have a high output stoma are prone to fluid and electrolyte imbalance and the expensive parenteral nutrition (PN) is necessary for management. In these cases, re-feeding can be beneficial with enriched stoma effluent. Methods: In our study we included 25 cases which had high output stoma with maximum bowel length of 140 cm from duodeno-jejunal junction or output greater than 1.5l in 24 hours. Results: Among these 25 cases, 16 were males and 9 females. The most common indications for making stoma were intestinal perforation (11) and gangrene (6). These cases were discharged on enriched re-feeding. No major complications were associated with re-feeding. None of the patients required parenteral nutrition after discharge from hospital. After getting body mass index (BMI) and serum albumin under normal parameters, we were able to close the stomas in all the patients. Conclusions: Patients with high output stoma can be managed nutritionally with distal enriched re-feeding. It is a cost-effective and effective alternate for parenteral nutrition (PN), which is associated with complications.

A clinician's perspective on the new organ mesentery and non-vascular mesenteropathies.

Mesentery was discovered as a new organ in 2017. It is a continuous membranous tissue from the duodenojejunal flexure to the anorectal junction. It has distinct anatomy, physiology, and disease states. Primary mesenteropathies include vascular and non-vascular diseases. Some of them are common, and some of them are rarely seen in clinical practice. Secondary mesenteropathies occur when infection or malignancy in another organ spreads to the mesentery. Each entity has specific diagnostic and treatment protocols. Increased awareness of different mesenteropathies and an understanding of their various presentations at different stages of life can help in early diagnosis and improved clinical outcomes.

Mesenteric Base Width: Abdominal Wall Diameter Correlates With Intestinal Rotational Anomalies in Infants

IntroductionSymptomatic malrotation requires urgent Ladd procedure. Patients with incidental or indeterminate findings have historically been managed with observation or operatively. Fluoroscopic identification of the duodenojejunal junction (DJJ) and ileocecal junction (ICJ) can guide operative decision-making, but algorithms have not been validated. This study aimed to determine whether fluoroscopic mesenteric base width (MBW) standardized to abdominal wall diameter (AWD) correlates with intraoperative anatomy in infants. MethodsWe retrospectively reviewed patients between 2013 and 2023 who were <1 year with fluoroscopy identifying DJJ and ICJ. Infants with normal rotation evaluated for digestive concerns were included. Congenital conditions with intestinal nonrotation were excluded. Two radiologists independently measured MBW as a diagonal line from DJJ to ICJ and maximal transverse AWD from inferior ribs. A ratio was calculated and compared between groups. Wilcoxon rank-sum and Kruskal–Wallis tests with p < 0.05 were considered significant. Area under the receiver operating characteristic curve (AUROC) was used to identify optimal ratio cutoff. ResultsFifty-eight patients, 22 normally rotated and 36 with intestinal rotational abnormality (IRA), met inclusion criteria. Preoperative radiographic concern for malrotation differed between groups (p < 0.0001). Median MBW:AWD was significantly lower in IRA than normal rotation based on imaging (0.31 vs 0.65, p < 0.0001). Optimal MBW:AWD of 0.55 had an AUROC of 0.9578. ConclusionsRadiographic measurement of MBW:AWD accurately predicted IRA from normal rotation with an optimal ratio cutoff of 0.55. Further validation will determine whether this ratio should play a role in management of incidental IRA or indeterminate findings on UGI. Level of EvidenceIII.

Development and validation of a nomogram for predicting the placement of nasointestinal tubes in critically ill patients based on abdominal radiography: A single-center, retrospective study

BackgroundEnteral nutrition administered via the nasointestinal tube (NET) is a prevalent nutritional modality among critically ill patients, and abdominal radiographs hold significant value in accurately ascertaining the precise positioning of the NET subsequent to its placement. Therefore, we propose an innovative approach to construct a clinical prediction model based on NET's configuration within the gastrointestinal tract in abdominal radiography. This model aims to enhance the accuracy of determining the position of NETs after their placement. MethodsPatients admitted to the intensive care unit of Zhejiang Provincial People's Hospital between October 2017 and October 2021 were included to constitute the training cohort for retrospective analysis, and nomogram was constructed. Consecutively enrolled patients admitted to the same hospital from October 2021 to October 2023 were included as the validation cohort. The training cohort underwent a univariate analysis initially, followed by a multivariate logistic regression approach to analyze and identify the most appropriate model. Subsequently, nomogram was generated along with receiver operator characteristic curves, calibration curves, and decision curves for both the training and validation cohorts to evaluate the predictive performance of the model. ResultsThe training and validation cohorts comprised 574 and 249 patients, respectively, with successful tube placement observed in 60.1 % and 76.3 % of patients, correspondingly. The predictors incorporated in the prediction maps encompass the “C-shape,” the height of “inverse C-shape,” showing the duodenojejunal flexure, and the location of the head end of the NET. The model demonstrated excellent predictive efficacy, achieving an AUC of 0.883 (95 % CI 0.855–0.911) and good calibration. Furthermore, when applied to the validation cohort, the nomogram exhibited strong discrimination with an AUC of 0.815 (95 % CI 0.750–0.880) and good calibration. ConclusionThe combination of abdominal radiography and NET's configuration within the gastrointestinal tract enables accurate determination of NET placement in critically ill patients.

A Rare Case of Complex Left Paraduodenal Hernia with Cocoon Abdomen

Paraduodenal hernias are rare congenital hernias that account for approximately 0.2-0.9% of all internal hernias. Among them, left paraduodenal hernias are even rarer, with an incidence of about 0.8%. Cocoon abdomen, also known as sclerosing encapsulating peritonitis, is a rare condition characterized by the encapsulation of the small bowel by a thick fibrous membrane, leading to intestinal obstruction. We present a rare case of a 45-year-old female patient who presented with complaints of left upper abdominal pain, intermittent vomiting, and abdominal distension for two months. Imaging studies revealed a complex left paraduodenal hernia with cocoon abdomen, leading to subacute intestinal obstruction. The patient underwent exploratory laparotomy, reduction of small bowel contents from the hernial sac, excision of the hernial sac, extensive adhesiolysis, and closure of the hernial defect. Intraoperatively, the entire small bowel from the duodenojejunal flexure to the ileocecal junction was encased in a thick peritoneal sac, with dense interbowel adhesions and a thick hernial sac. The postoperative course was complicated by paralytic ileus, which was managed conservatively. The patient recovered well and was discharged on a low-residue diet and appropriate medications. This case highlights the rare coexistence of a left paraduodenal hernia and cocoon abdomen, emphasizing the importance of early diagnosis and timely surgical intervention to prevent potential life-threatening complications

Intrajejunal levodopa in Parkinson's disease: Optimization of PEG application

The various forms of Percutaneous Endoscopic Gastrostomy (PEG) are highly relevant in neurology, as pump-administered intrajejunal levodopa application is one of the indispensable forms of therapy in advanced Parkinson's disease. Optimal PEG placement and follow-up are therefore significant for the success of the therapy. However, the standard intrajejunal administration of levodopa gel via a JET-PEG, i. e. a PEG with an internal catheter inserted into the jejunum, is not without problems for various reasons. In particular, the considerable cumulative complication rates demand a reconsideration of the situation. The very limited absorption area of the drug in the region of the flexura duodenojejunalis must also be taken into account. Causes of complications are predominantly a non-optimal application technique of PEG and internal catheter as well as the frequent lack of an adequate follow-up. In this paper, the details of a modified and optimized application technique compared to the conventional techniques are presented. These new methods have proved their usefulness in clinical applications for years, and additionally a new application form, the Hybrid-PEG, is presented. However, many of the details derived from anatomical/physiological, surgical and endoscopic aspects must be strictly observed during the application in order to reduce or avoid minor and major complications. In particular, problems are caused by local infections in the area of the insertion point of the PEG including peritonitis, leaks and buried bumper syndrome (BBS). The relatively frequent dislocations of the internal catheter also prove to be particularly troublesome. These can ultimately be avoided by clip fixation of the catheter tip down in the jejunum. In particular, the use of the newly developed Hybrid-PEG, a combination of endoscopically controlled gastropexy with three sutures and subsequent central thread-pull-through of the PEG tube, can significantly reduce the complication rate and thus achieve a decisive improvement for patients. The aspects discussed here are highly relevant for all those involved in the therapy of advanced Parkinson's disease. Trustful interdisciplinary collaboration between neurology and endoscopy/surgery/gastroenterology is a prerequisite for good clinical outcomes.

A case of intermittent bilious emesis in a term neonate: a case report and brief review of literature

BackgroundNeonatal intestinal obstruction is a complex condition that poses challenge in management. Prompt recognition and appropriate management are crucial to prevent complications. We present a case of a term neonate with intermittent bilious vomiting.Case presentationThe baby underwent routinely performed investigations, including abdominal radiography and ultrasound, which provided inconclusive results. However, contrast-enhanced computed tomography revealed a web at duodenojejunal flexure. Exploratory laparotomy confirmed the diagnosis, and surgical intervention was performed. The baby’s postoperative course was prolonged with a gradual transition from parenteral nutrition to enteral feeds.ConclusionThis case highlights a rare cause of intestinal obstruction, the unusual location of duodenal web, the importance of maintaining a high index of suspicion for intestinal obstruction, even in the absence of classical signs, and the value of utilizing contrast-enhanced computed tomography when initial investigations are inconclusive.

NON-SURGICAL MANAGEMENT OF PERFORATED JEJUNAL DIVERTICULUM

Jejunal diverticulitis complicated by perforation is rare and shows an uncharacteristic presentation and thus poses a difficulty in the early diagnosis ofthe condition.However, diverticulitis and its complications should always be considered in geriatric men who present with an acute abdomen. We describe a 77-year-old man who originally presented with acute abdominal pain having free gas under right dome of diaphragm on X-ray abdomen, upon further evaluation with CT abdomen, a diagnosis of contained jejunal diverticular perforation was made.Onceoptimized he was then managed non-operatively with intravenous fluids, antibiotics, and total parenteral nutrition and supportive care. His overall recovery during hospitalization was uneventful. A follow-up CT abdomen showed no new pocket of fluid or free air. As jejunal perforation is a rare finding, early laparotomy done based upon free gas on X-ray alone may be correlated with an overall higher risk of mortality due to the diseases proximity to duodenojejunal flexure and thus conservative management in selected group of patients may prevent inadvertent celiotomy and morbidity and mortality arising out of it.

Foreign Body Ingestion in Children: An Experience of 99 Cases in a Tertiary Care Center in Delhi.

Accidental ingestion of foreign bodies in children is critical, as the inability to effectively communicate can potentially lead to devastating consequences. We aimed to determine the epidemiology of foreign body ingestion and variability according to age, gender, type, and location of foreign body, and describe its management. The aim was to study the various types of foreign body ingestions in children admitted to pediatric surgery and their management. A retrospective study was conducted from January 2020 to June 2022 on children under the age of 12 years with a confirmed diagnosis of foreign body ingestion. Patients were clinically and radiologically assessed, after which standard protocols were followed wherein patients were followed by either observation or emergent management. Emergent management included removal of the foreign body by either endoscopy or surgery. Comparisons among multiple age groups, gender, type of foreign body, location of foreign body, and their management were analyzed. Out of 99 subjects in our study, there were 76 boys and 23 girls. The median age of presentation was 5 years. Most children were asymptomatic at presentation. The most frequently ingested foreign body was a coin in all age groups. The majority of the foreign bodies were suspected to be in the small bowel. The foreign bodies that had crossed the duodenojejunal flexure (n = 74, 74.7%) were managed conservatively with the observation of a variable period of a minimum of 24 h and a maximum of 48 h. 21 cases were managed by endoscopic removal, while three cases required surgical intervention. Overall, the most common gastrointestinal foreign body was a coin in all age groups. Button battery is the most worrisome foreign body; however, depending on its position, it can be managed conservatively. Upper GI foreign bodies can be safely removed endoscopically. Parental counseling is very important for the prevention of ingestion of foreign bodies.

Acute superior mesenteric artery thrombosis in a 34-year-old male with thrombophilia: a case report

Introduction: Thrombophilic state, marked by extensive formation of blood clots within the vascular system poses a formidable peril, leading to loss of circulatory integrity and systemic well-being. Superior mesenteric artery (SMA) thrombosis is a serious medical disorder characterized by the obstruction of the arterial blood flow to the gastrointestinal tract, which is associated with significant morbidity and mortality. The condition has a plethora of etiological causes. Vague abdominal pain is a common clinical manifestation, and there is a very high mortality rate.Case Presentation: A 34-year-old Pakistani male presented with rapidly worsening acute abdominal pain over a 10-hour period. Clinical examination revealed elevated blood pressure, while other vital signs remained within normal limits. Abdominal examination findings were inconclusive compared to the patient's severe abdominal pain complaint. Contrast-enhanced CT scan indicated a large thrombus in the superior mesenteric artery with radiological features suggestive of intestinal ischemia, extending from the duodeno-jejunal flexure to the mid-transverse colon. Subsequently, the patient underwent exploratory laparotomy with extensive bowel resection and received anticoagulant therapy. He subsequently experienced compensated right lower limb ischemia, treated conservatively with high-dose anticoagulant therapy. Within days, bowel anastomotic leak developed, requiring multiple surgeries. Eventually, the patient progressed to septic shock, followed by multiorgan failure, culminating in a fatal cardiac arrest.Conclusion: Acute mesenteric ischemia, a rare abdominal emergency with an incidence of 6 per 100,000, is associated with a substantial mortality rate, ranging from 58% to 93% among diagnosed cases. The challenges posed by SMA thrombosis include diagnostic complexities, as it frequently manifests with symptoms disproportionate to clinical signs, and results in catastrophic complications, necessitating high suspicion index and prompt intervention.

A49 AN UNEXPECTED CASE OF SEVERE PROTEIN-LOSING ENTEROPATHY IN A TODDLER

Abstract Background Protein-losing enteropathies (PLE) are characterized by excess loss of serum proteins into the gastrointestinal tract, resulting in hypoproteinemia, peripheral edema, and related respiratory and cardiac sequelae. PLE should be suspected in patients with hypoproteinemia not explained by protein malnutrition, impaired hepatic protein synthesis, or renal losses, and can occur as a consequence of erosive or non-erosive gastrointestinal diseases, and conditions that alter lymphatic flow. Aims To present a case of intestinal malrotation with chronic volvulus presenting as PLE. Methods In this report, we describe a pediatric patient presenting with PLE ultimately found to have intestinal malrotation with chronic volvulus. Results A healthy 1-year-old male presented with acute non-bloody diarrhea and peripheral edema on a background of recurrent colicky abdominal pain and non-bilious emesis. He had significant electrolyte derangements at presentation including hypokalemia, hyponatremia, hypomagnesemia, and metabolic acidosis, with additional laboratory findings of hypoalbuminemia (11g/L), hypogammaglobulinemia (IgA 0.11g/L, IgG 0.77g/L, IgM 0.28g/L), lymphopenia (0.4x10E9/L), and fat-soluble vitamin deficiency (Vitamin A 0.5umol/L, 25-Hydroxyvitamin D 18.4nmol/L, Vitamin E 6umol/L, INR 1.7). In addition to abdominal imaging, he underwent endoscopic evaluation which did not identify an underlying etiology. As his presentation was consistent with PLE, a high-protein, low-fat diet was initiated. Despite dietary adherence for 16 weeks, the PLE features persisted with ongoing severe hypoalbuminemia (20g/L). Given a suspicion of intestinal lymphangiectasia, a capsule endoscopy was arranged. In the interim, the patient had recurrence of abdominal pain and emesis prompting a repeat abdominal ultrasound which demonstrated swirling of the mesenteric vessels in the midline. An upper gastrointestinal series identified a short mesenteric root with the duodenojejunal junction and cecum in proximity. Urgent laparotomy confirmed a 720-degree volvulus of the small bowel around the mesenteric root, with an abnormally positioned duodenojejunal flexure and cecum. This was presumed to be chronic given the absence of acute vascular compromise. The patient underwent a Ladd procedure. He had complete resolution of symptoms and PLE features on a liberalized diet. Conclusions This report identifies a case of intestinal malrotation with chronic volvulus presenting as PLE, highlighting an atypical presentation of intestinal malrotation outside the neonatal period. Awareness of these atypical presentations is important to facilitate prompt diagnosis and treatment, thereby reducing the rate of complications. Funding Agencies None

Clinical outcomes of different types of metallic stents in malignant distal duodenum stenosis: A retrospective study

Background/purposeEndoscopic stenting at malignant distal duodenum stenosis (MDDS) is challenging because of the duodenal C-loop configuration, the acute angle of the duodenojejunal junction, and the limited length of the endoscope. Few studies have investigated the clinical outcomes of stenting at the distal duodenum. Therefore, this study aimed to investigate the clinical outcomes of treating MDDS with different types of metallic stents. MethodsFrom January 2012 to December 2020, fifty-six patients with MDDS who underwent duodenal stenting were enrolled for analysis. Thirty-five patients received uncovered self-expandable metallic stents (UC-SEMS), and twenty-one patients received partially covered self-expandable metallic stents (PC-SEMS). All patients were followed up till death or for 18 months. The clinical success rate, stent dysfunction rate, and stent patency were compared between the groups. Multivariate analysis was conducted to identify factors related to stent dysfunction. ResultsThe clinical success rates were 85.7 % in both the UC-SEMS and PC-SEMS groups. Stent dysfunction rates (UC-SEMS: 34.3 %, PC-SEMS: 38.1 %, p = 0.773) and the average stent patency (UC-SEMS: 117.2 days, PC-SEMS: 100.0 days, p = 0.576) were not statistically different between the groups. Multivariate analysis disclosed the age ≥65 years was significantly related to stent dysfunction (odds ratio: 4.78, p = 0.031). ConclusionBoth UC-SEMS and PC-SEMS are safe and effective treatment options for MDDS. However, stent dysfunction remains a significant issue to overcome, particularly in the elderly. Further research is needed to explore novel strategies that can improve the effectiveness of stent placement and reduce the risk of stent dysfunction.

Small Bowel Perforation at the Duodeno-Jejunal Junction from a Migrated Biliary Stent: A Case Report

Background: The most common sites of reported bowel perforation secondary to migrated biliary stents were duodenal or colonic. However, small bowel perforations were reported in a few cases. Herein we present a case of small bowel perforation secondary to migrated biliary plastic stent at the duodeno-jejunal junction (DJ). We think this peculiar site is the first to be reported as a perforation site secondary to migrated biliary stent. Case Presentation: We present the case of female Egyptian patient with severe abdominal pain and air under diaphragm after Endoscopic Retrograde Cholangiopancreatography (ERCP) for Klatskin tumor. The patient underwent a midline laparotomy. A moderate collection of enteric fluid was encountered with migrated stent causing perforation of the small intestine at DJ. The stent was removed, and primary closure was done. The patient could not be extubated due to bad chest condition and admitted to ICU for 48 hours then extubated after improvement of the chest condition and ability of the patient to maintain good oxygen saturation in room air. Unfortunately, the patient developed massive pulmonary embolism on the fifth postoperative day and died. Conclusion: Suspicion of stent migration should be put in mind in any patient presented with abdominal pain with history of previous ERCP and biliary stenting. Endoscopic removal and mucosal repair are possible in select cases. This is still not available for DJ or small bowel. Further research and future innovations may overcome this challenge.

IBC-Oxford University2023_BJSOral_18The Use of Indocyanine Green (ICG) Fluorescence Angiography in Laparoscopic Roux-en-Y Gastric Bypass for Perfusion Assessment and Structure Visualisation

Abstract Introduction Indocyanine green (ICG) fluorescence angiography (FA) has been utilised in bariatric surgery for assessment of tissue perfusion and blood supply in laparoscopic sleeve gastrectomy (LSG). However, there is limited literature on its use in laparoscopic Roux-en-Y gastric bypass (LRYGB). The aim of this study was to evaluate the use of ICG-FA in LRYGB for qualitative assessment of tissue perfusion and structure identification. These are the first cases utilising ICG-FA in LRYGB to be performed in the United Kingdom. Methods Thirty-five patients (12 male, 34%, 23 females, 66%) with median (IQR) age of 45 (38 – 52) years and preoperative median (IQR) BMI 45 (37 – 49) kg/m2 underwent LRYGB with ICG-FA. ICG was administered intravenously according to an agreed protocol. Karl Storz® Image 1 Rubina system with overlay and monochromatic modes was utilised for perfusion assessment. ICGFA was utilised for qualitative assessment of gastric pouch perfusion before and after linear stapled gastro-jejunal anastomosis and visualisation of key anatomical landmarks. The perfusion pattern was assessed by the operating team based on a ICG scoring system (ICG-S), which ranged from 1 (no perfusion) to 4 (excellent perfusion) based on timing following ICG injection and intensity of fluorescence detected in the anatomical structures. Results From April 2021 to August 2022, 34 patients underwent primary LRYGB with use of ICG- FA. ICG was utilised in one revisional case. No adverse effects to ICG were observed. ICG-S was 4 in 33 patients. (94%). In two patients (6%), operative strategy was modified based on focal area of no perfusion (ICG score 1) in gastric pouch. ICG-FA helped improve operative safety during division of omentum and in recognition of duodeno-jejunal flexure with fluorescence detection in epiploic vessels and inferior mesenteric vein (IMV) respectively. There were no leaks at a median follow up of 9 months. Conclusion ICGFA imaging allows for qualitative assessment of perfusion and identification of critical anatomical landmarks during LRYGB. The technology is safe and its utilisation in LRYGB provides a “real-time image” of gastric pouch perfusion, helping to demonstrate ischaemic or poorly perfused areas with an opportunity to modify operative strategy.

Ultrasound as the first line investigation for midgut malrotation: a UK tertiary centre experience

To present the first 22-months experience of transitioning to an ultrasound-first pathway for suspected midgut malrotation. An "ultrasound-first" imaging pathway was initiated in October 2021. Twenty-two-months later, a search was undertaken of all <1-year-old patients with "bilious", "malrotation," or "volvulus" as the imaging indication. Reports and images from upper gastrointestinal fluoroscopy (UGI) and ultrasound were reviewed, and diagnoses and outcomes were documented. The search yielded 101 eligible cases between October 2021 and July 2023. Of the patients, 63/101 (62%) had both ultrasound and UGI: 47/63 (75%) ultrasound first, 16/63 (25%) UGI first. Thirty-one per cent (31/101) had ultrasound only and 7/70 (10%) UGI only. The pathway diagnosed 7/8 (88%) infants with midgut malrotation with or without volvulus and one infant who had an inconclusive ultrasound examination with a suspected an internal hernia and who was found to have malrotation volvulus at surgery. Twenty-one infants who had confidently normal ultrasound examinations and who also had UGI all had a normal duodenojejunal flexure position. Ultrasound detected alternative pathology in eight children. Duodenal visualisation improved with time: 6/15 (40%) in the first 6 months to 23/34 (68%) after the first year. The transition to ultrasound as the first diagnostic test for midgut malrotation can be done safely and effectively in a UK centre, which previously relied solely on UGI.
