Primary axillary hydatid cyst: A case report

BACKGROUND

Hydatid disease, also known as echinococcosis, is an endemic parasitic infection, most commonly caused by Echinococcus granulosus. It may affect any organ resulting in the formation of hydatid cysts, but most frequently involves liver and lungs. Hydatid cyst arising primarily from axilla is an extremely rare manifestation of this condition, with only a few cases reported in medical literature.

CASE PRESENTATION

Here we present the case of a 32-year-old Indian male farmer, who presented with a painless, slow-growing mass in the left axillary region of 8 months duration. Preoperative imaging led us to the diagnosis of primary axillary hydatid cyst, with no other associated cysts or masses anywhere else in the body. Following antihelmintic therapy, the cyst was surgically excised without rupture. The diagnosis was further confirmed by macroscopic and histopathological examination.

CONCLUSION

This case report highlights the importance of considering hydatid cyst in the differential diagnosis of palpable masses in the axillary region, especially in regions where the disease is endemic. Early recognition and accurate diagnosis are crucial for appropriate management and optimal patient outcomes.

Is there a link between Spigelian and inguinal hernias? A case series

INTRODUCTION

Spigelian hernias are among the rare primary ventral hernias. Diagnosis is often difficult, as many cases are asymptomatic. Spigelian and inguinal hernias are usually considered separately in current scientific literature. With this case series, we want to illustrate a possible relationship between the neighboring hernia types.

METHODS

In this article, we report on a case series of Spigelian hernias that were operated on in five hernia centers in the period from January 1st, 2021 to October 31st, 2023. We have summarized all patient characteristics with previous operations and the result of the secondary operation.

RESULTS

We report a case series with 24 Spigelian hernias, 15 of which have a connection to previous inguinal hernias. In these cases, however, it is not certain whether these are primarily overlooked or occult hernias or whether these Spigelian hernias have arisen secondarily, as a result of previous hernia surgery. With this case series, we would like to point out a possible connection between Spigelian hernia and inguinal hernia. Further studies are needed to shed more light on this entity and explain its genesis.

Abdominal hernias secondary to non-penetrating trauma. A systematic review

Traumatic abdominal wall hernia (TAWH) is a protrusion of contents through a defect in the abdominal wall as a consequence of a blunt injury. The objective of this review was to describe demographic and clinical aspects of this rare pathology, identifying the optimal moment for surgical intervention, evaluating the need to use mesh, and analyzing the effectiveness of surgical treatment. Thus, a systematic review using PubMed, Embase, and Scopus databases was carried out between January 2004 and March 2024. Computed tomography is the gold-standard imaging test for diagnosis. Open surgery is generally the preferred approach, particularly in emergencies. Acute TAWH can be treated by primary suture or mesh repair, depending on local conditions, while late cases usually require mesh.

New classification of Amyand's hernia, our experience: a retrospective observational study with a literature review

Purpose

Amyand's hernia (AH) is the name given to the type of hernia in which the appendix is found in a hernial sac. We aimed to share our clinical experience with a literature review for AH.

Methods

A total of 1,774 inguinal hernias and 13 AH cases were repaired in our clinic between 2009 and 2020. In addition, detailed clinical features about AH were extracted by including unpublished data of 165 cases, which were gathered from the extensive literature on childhood AHs using PubMed, Web of Science, and Cochrane databases.

Results

The rate of AH was 0.73% in all inguinal hernias; this rate was 8.6% for incarcerated hernias. The average age was 5.74 ± 7.27 months for AH. Our AH cases were seen in males and on the right side. AH is seen in 97.3% of males according to a review of 69 articles. The average age was 16.78 ± 30.46 months. One hundred sixty-five of the AH cases were on the right (88.7%). The main symptoms were swelling or redness in the inguinal region, pain, fever, and vomiting, along with patients presenting septic or with stercoral fistula.

Conclusion

If the appendix is normal and easily reduced, high ligation is sufficient. In cases where reduction is difficult and/or the appendix is inflamed, appendectomy and hospitalization should be performed.

Spontaneous Acquired Diaphragmatic Hernia: Case Series and Review of Literature

Congenital diaphragmatic hernia (CDH) and acquired diaphragmatic hernia (ADH) are secondary to a weakness or opening in the diaphragm. Both are types of internal hernia. The abnormality can range from a minor defect in the posterior edge of the diaphragm to the entire loss of it. CDH usually leads to lung hypoplasia associated with pulmonary hypertension and immaturity, as well as cardiac dysfunction. In ADH, pathophysiology is secondary to herniation and its pressure effects. We report a series of two cases of spontaneous ADH (SADH). Spontaneous acquired rupture of the diaphragm can occur after exercise, coughing, labor (delivery), or even without any significant preceding event. It is uncertain if SADH is caused by a preexisting weak region in the diaphragm, a loss of muscle coordination during vigorous exertion, or both. It is a potentially fatal surgical emergency requiring a high index of clinical judgment in the appropriate clinical setting. SADH acts mechanically by compressing the lung. It is an infrequent entity. This case series and review concisely illustrate the genesis, diagnosis, and treatment of spontaneous diaphragmatic hernia.

Mechanical Analysis of a Novel Sternal Closure System in Static Tensile Loading

The most common means of sternal closure after sternotomy is stainless steel wire cerclage. These wires, while inexpensive and simple in design, are known to be associated with low strength and sternal dehiscence. In this biomechanical analysis, we compare single sternal wires, double sternal wires, and a novel sternal closure device we have designed to mitigate sternal dehiscence. The device uses polymer grommets at the sternal interfaces to distribute load over a large surface area of bone. Samples of each closure device were installed in a bone model and distracted at a rate of 10 mm/min while tensile forces were continuously measured and compared. Single wires generated the lowest stiffness and strength values, followed by the double wires. The novel device demonstrated significantly higher stiffness and strength at all displacements compared with the single and double wires. Clinical use of this device may result in meaningful reduction in complications associated with the use of standard sternal wires such as sternal separation and fracture.

Amyand's Hernia: A Snap From the Learned Mind

Amyand's hernia is a rare clinical condition containing appendix as the content of hernia. The incidence of this type of hernia is rare; the appendix may become incarcerated within the sac and can lead to strangulation or perforation. This case report highlights the clinical presentation, diagnosis, and management of an Amyand's hernia in a strangulated masquerade in a 75-year-old male. It signifies the importance of early recognition and prompt surgical intervention to counteract potential complications associated with this condition.

Kidney re-transplantation in the ipsilateral iliac fossa: a surgeon's perspective on perioperative outcome

Background

Compared with primary transplantation, ipsilateral renal re-transplantation is associated with an increased risk of surgical complications and inferior graft outcomes. This study investigates whether an ipsilateral re-transplantation approach per se is an independent risk factor for surgical complications and early graft loss.

Methods

In this retrospective, single-centre analysis, surgical complications and early graft outcomes of ipsilateral kidney re-transplantations from January 2007 to December 2017 were compared with primary transplantations and contralateral re-transplantations. Univariate and multivariate binary logistic regression analyses were performed to identify risk factors for surgical complications requiring surgical revision and graft loss within the first year after transplantation.

Results

Of the 1489 kidney transplantations, 51 were ipsilateral, 159 were contralateral re-transplantations and 1279 were primary transplantations. Baseline characteristics did not differ between the ipsilateral and contralateral re-transplant recipients except for current and highest panel reactive antibody levels. Major complications requiring surgical revision were significantly more frequent in ipsilateral re-transplantations (P = .010) than in primary transplantations but did not differ between ipsilateral and contralateral re-transplantations (P = .217). Graft loss within the first year after transplant was 15.7% in the ipsilateral versus 8.8% in the contralateral re-transplant group (P = .163) versus 6.4% in the primary transplantation group (P = .009). In a multivariate regression model, ipsilateral re-transplantation was not identified as an independent risk factor for complications requiring surgical revision or first-year graft loss.

Conclusions

Ipsilateral renal re-transplantation is not a risk factor for inferior outcomes. Graft implantation into a pre-transplanted iliac fossa is a feasible and valid therapeutic option.

Biomechanical comparison of bone staple fixation methods with suture material for median sternotomy closure using 3D-printed bone models

AIM

To compare the biomechanical properties of three different sternal closure techniques in a 3D-printed bone model of a sternum from a 30-kg dog.

METHODS

Median sternotomy was performed on a total of 90 three-dimensional (3D) copies of a polycarbonate (PC) model of a sternum, generated from the CT images of the sternum of a 30-kg German Shepherd dog. Three different methods were used to repair the sternotomies: polydioxanone suture (group PDS, n = 30), stainless steel bone staples (group SS, n = 30), and nitinol bone staples (group NS, n = 30). Each repair method was tested by applying tensile force in one of three ways (longitudinally, laterally, or torsionally) resulting in a sample size of n = 10 for each repair method-loading combination. In all experiments, the loads at 1-mm and 2-mm gap formation, failure, and the displacement at the failure point were measured.

RESULTS

In lateral distraction and longitudinal shear tests, NS and SS staple repairs required application of significantly greater force than PDS across all displacement criteria (1 and 2 mm). NS exhibited significantly greater failure load than PDS. In torsion tests, NS required significantly greater application of force compared to SS or PDS at all displacement criteria (1 and 2 mm) and exhibited a greater failure load than PDS. In terms of displacement at failure point, PDS suture showed more displacement than SS or NS across all experiments (laterally, longitudinally, torsionally).

CONCLUSIONS

In this study, bone staples were mechanically superior to PDS suture in median sternotomy closure using 3D-printed bone model in terms of 1-mm, 2-mm displacement loads, and displacement at failure. NS had a higher failure load than PDS under lateral, longitudinal, and torsional distraction.

CLINICAL RELEVANCE

These study results imply that bone staples can be considered as an alternative surgical method for median sternotomy closure in dogs.

A Case of Amyand's Hernia With Abscess Managed by Two-Stage Surgery: Elective Hernia Mesh Repair Following Emergency Laparoscopic Appendectomy

An 82-year-old man presented to our emergency department with a bulge in the right groin and worsening pain that had been present for one week. An abdominal computed tomography scan revealed fluid collection within a right inguinal hernia and a thickened appendix within the hernia sac. The patient underwent an emergency laparoscopic appendectomy under a diagnosis of Amyand's hernia with peri-appendicular abscess. During surgery, the incarcerated appendix was pulled back into the abdominal cavity from the hernia sac, and the perforated appendix was resected. For drainage of the abscess, a drain tube was laparoscopically placed into the hernia sac through the internal inguinal ring. Considering the risk of mesh infection and wound infection, the patient underwent appendectomy alone but not hernia repair at this time. Two months later, Lichtenstein repair using mesh was performed as a second-stage procedure. For Amyand's hernia with abscess, this type of two-stage strategy may avoid the surgical site infection, and the use of mesh in a second procedure would minimize the possibility of hernia recurrence, unlike previously reported cases treated by concomitant appendectomy and hernia repair.

A Case Report of Inguinal Hernia Containing the Appendix: Amyand's Hernia

Numerous types of hernias have been reported in the literature. A unique and uncommon type of hernia known as an Amyand's hernia occurs when the inguinal sac contains the vermiform appendix. Due to its rarity, it is usually difficult to diagnose and often goes unreported. However, when it goes unnoticed and untreated, it can lead to complications such as strangulation and perforation. This is where medical imaging plays a pivotal role. This case study aims to provide an overview of Amyand's hernia while highlighting the vital role that imaging plays in diagnosing the condition, identifying any associated problems, characterizing the pathology, and classifying the hernia. This supports grading the severity and determining the appropriate course of management.

Primary Liver Transplant in Biliary Atresia: The Case for and Against

The role of liver transplantation as a primary procedure in biliary atresia has been argued over for at least 40 years, indeed since the coming of age of safe liver transplantation during the 1980s. Yet, it is not a common option in most series (usually ≤5%) and typically reserved for those with late presentations (arguably >100 days) with established cirrhosis. This review presents the pros and cons of primary liver transplant. The pros are based upon the observation that at best a Kasai portoenterostomy (KPE) is simply palliative in most, and at worse has no effect whatsoever on restoration of bile flow and is therefore pointless. Set against this are the cons: there is a dearth of prognostic tests (clinical, biochemical, or histological) at the time of presentation which may predict inevitable failure; the possibility of long-term native liver survival to adulthood in a proportion (albeit a minority); and the implied increased need for donor organs suitable for infants - a stressor for an already overstressed system. Improving results from KPE in terms of increasing the proportions clearing their jaundice and minimizing the effects of chronic liver fibrosis and cirrhosis would surely limit the siren calls for primary transplants but the key must be better discrimination at presentation with the use of biomarkers (circulatory or histological, individually or together) to enable better decision making.

Amyand's Hernia diagnosed preoperatively via a CT scan: A case report

Amyand's hernia is a rare type of inguinal hernia characterized by the presence of the vermiform appendix within the hernia sac. It was named after Claudius Amyand who performed the world's first successful appendectomy on an 11-year-old boy with a right inguinal hernia in 1735 and discovered a herniated appendix during surgery. This condition warrants urgent surgical treatment, with the type of surgical intervention depending on the appendix's condition. However, the nonspecific clinical presentation often complicates the preoperative diagnosis, emphasizing the critical role of imaging in surgical planning. Herein, we present the case of a 74-year-old male who presented with fever, inguinal swelling, and discomfort. Clinical suspicion of inguinal and scrotal inflammation prompted us to perform a prompt CT scan. This radiological evaluation led to a preoperative diagnosis of a Type 3 Amyand's hernia. This case highlights the significance of CT scans in the accurate and timely diagnosis of Amyand's hernia. Distinguishing between various types of Amyand's hernia is pivotal as it profoundly influences surgical decision-making and postoperative outcomes. By sharing this case, we contribute to current knowledge about Amyand's hernia, increase clinical awareness of the condition, and emphasize the crucial role of imaging in its management.

Recipient-associated risk factors for post-liver transplantation biliary complications: A cohort study

INTRODUCTION

Biliary complications (BCs) are a well-documented post-liver transplantation concern with potential implications for patient survival. This study aims at identifying risk factors associated with the development of BCs in recipients after liver transplantation (LT) and exploring strategies for their management.

METHODS

We conducted a retrospective analysis of 1595 adult patients (age > 18 years) who underwent LT surgery between 2019 and 2021. The study assessed the incidence of BCs in this cohort.

RESULTS

Of 1595 patients, 178 (11.1%) experienced BCs, while 1417 (88.8%) did not exhibit any signs of such complications. Patients who developed BCs were found to have a significantly lower average age (p < 0.001) and longer cold ischemic times (p < 0.001) compared to those without BCs. Variables such as sex, body mass index (BMI), model for end-stage liver disease (MELD) score, primary diagnosis, type of anastomosis, hepatectomy technique, type of transplanted liver and mortality did not demonstrate statistically significant differences between the two groups (p > 0.05). Univariate logistic regression analysis revealed that a cold ischemic time exceeding 12 hours and duct-to-duct anastomosis were positive predictors for BC development (odds ratios of 6.23 [CI 4.29-9.02] and 1.47 [CI 0.94-2.30], respectively). Conversely, increasing age was associated with a protective effect against BC development, with an odds ratio of 0.64 (CI 0.46-0.89).

CONCLUSION

Our multi-variate analysis identified cold ischemia time (CIT) as the sole significant predictor of post-liver transplantation biliary complications. Additionally, this study observed that advancing patient age had a protective influence in this context. Notably, no significant disparities were detected between hepatectomy techniques and the etiology of liver disease types in the two study groups.

Controlled release of vancomycin from PEGylated fibrinogen polyethylene glycol diacrylate hydrogel

Surgical site infection (SSI) is a common issue post-surgery which often prolongs hospitalization and can lead to serious complications such as sternal wound infection following cardiac surgery via median sternotomy. Controlled release of suitable antibiotics could allow maximizing drug efficacy and safety, and therefore achieving a desired therapeutic response. In this study, we have developed a vancomycin laden PEGylated fibrinogen-polyethylene glycol diacrylate (PF-PEGDA) hydrogel system that can release vancomycin at a controlled and predictable rate to be applied in SSI prevention. Two configurations were developed to study effect of the hydrogel on drug release, namely, vancomycin laden hydrogel and vancomycin solution on top of blank hydrogel. The relationship between the rigidity of the hydrogel and drug diffusion was found to comply with a universal power law, i.e., softer hydrogels result in a greater diffusion coefficient hence faster release rate. Besides, vancomycin laden hydrogels exhibited burst release, whereas the vancomycin solution on top of blank hydrogels exhibited lag release. A mathematical model was developed to simulate vancomycin permeation through the hydrogels. The permeation of vancomycin can be predicted accurately by using the mathematical model, which provided a useful tool to customize drug loading, hydrogel thickness and stiffness for personalized medication to manage SSI. To evaluate the potential of hydrogels for bone healing applications in cardiovascular medicine, we performed a proof-of-concept median sternotomy in rabbits and applied the hydrogels. The hydrogel formulations accelerated the onset of osteo-genetic processes in rabbits, demonstrating its potential to be used in human.

Left-Sided Intra-thoracic Ectopic Kidney With Symptomatic Bochdalek Hernia: A Case Report

A congenital defect in the diaphragm, known as a Bochdalek hernia (BH), is a condition that allows herniation of the abdominal viscera into the thorax. BH is the most common type of congenital diaphragmatic hernia (CDH) and is typically detected on the left side. An ectopic kidney is a rare condition. An intra-thoracic ectopic kidney is an extremely uncommon condition. In adult patients, the presence of BH with an intra-thoracic kidney is extremely uncommon and is often a finding discovered unintentionally. A 51-year-old male patient presented to the outpatient unit of the pulmonology department. He stated that he had been suffering symptoms such as coughing, wheezing, and breathing difficulties for one year. A chest X-ray showed a well-defined radio-opaque lesion in the lower left zone. A computed tomography (CT) scan of the chest demonstrated a defect in the posterolateral region of the left hemidiaphragm, as well as herniation of the left kidney and retroperitoneal fat in the left hemithorax. The intra-thoracic ectopic kidney was found to be normal in size and showed normal attenuation and enhancement, with the contrast being promptly excreted into the pelvicalyceal system during CT urography. Due to the hernia's small size and lack of abnormalities on CT urography, the patient was recommended a conservative treatment. A follow-up examination was performed on the patient annually. Throughout the follow-up period, there was not a single episode of kidney-related issues. To avoid unwanted image-guided biopsies and surgical procedures, it is imperative to look for intra-thoracic kidneys in patients presenting with a thoracic mass or an elevated hemi-diaphragm.

Primary Hydatid Cysts in the Extremities: A Systematic Review of the Literature

Primary hydatid cysts (PHCs) in the extremities are uncommon, presenting in the majority of cases with atypical clinical features. Radical surgical excision remains the mainstay of treatment. The aim of our study was to accumulate the already published data on PHCs in the extremities in terms of demographic, diagnostic, and therapeutic aspects. Three electronic databases were meticulously searched for articles published until 2024. A total of 85 studies comprising 118 patients were finally included in our review. Sixteen patients (13.5%) were diagnosed with a hydatid cyst in their upper extremity, 94 (79.7%) with a PHC in the lower extremity, and eight (6.8%) with an echinococcal cyst in the axilla. Pain and swelling were the most frequent symptoms, whereas only two patients were completely asymptomatic. The mean lesion size was 11.6 ± 7.1 cm. Preoperative serology investigation was reported in 82 out of 118 (69.5%) patients; among them, 33 (44.6%) cases had a positive preoperative serology test. The vast majority of patients (96.6%) were treated with an interventional procedure either surgical or radiological, and only seven experienced postoperative complications. No anaphylactic reaction was described perioperatively. Although preoperative diagnosis of PHCs is challenging, they should be considered in the differential diagnosis of soft tissue lesions. Treatment strategies should be individualized on a patient basis, while radical surgical excision remains the gold standard treatment.

Amyand's hernia: a case of right inguinoscrotal hernia with appendiceal content

Introduction

Amyand's hernia, a rare condition where the appendix becomes lodged in the inguinal canal, poses diagnostic challenges due to its varied clinical presentations and lack of distinctive radiological features. This case underscores the importance of early detection and comprehensive diagnostic evaluation.

Case Presentation

A 30-year-old male presented with a 2-year history of right inguinoscrotal swelling, culminating in agonizing symptoms and irreducible masses over the inguinoscrotal area. Despite the absence of significant medical history, diagnostic imaging confirmed a complete right inguinoscrotal hernia and bilateral hydrocele with internal echoes.

Clinical Discussion

The case illustrates the difficulties in preoperative diagnosis of Amyand's hernia, emphasizing the reliance on imaging modalities and clinical assessment. Successful surgical intervention involving appendectomy and hernioplasty highlights the necessity for prompt diagnosis and management.

Conclusion

This case exemplifies the challenges and complexities associated with Amyand's hernia, emphasizing the importance of early recognition and comprehensive surgical planning. Moving forward, increased clinical vigilance and awareness are essential to ensure optimal patient outcomes in cases of inguinoscrotal pathology.

Accidental Toothbrush Ingestion

The accidental ingestion of a toothbrush is an extremely rare occurrence, typically involving young women with psychiatric disorders such as schizophrenia, bulimia, or anorexia nervosa. There are no known cases of a swallowed toothbrush being expelled naturally through the rectum. Therefore, prompt extraction of an ingested toothbrush from the gastrointestinal tract using a surgical or endoscopic method is a necessity. Here, we report a case of a psychologically healthy woman ingesting a toothbrush accidentally while cleaning her tongue with the back of the toothbrush. In our report, we document the successful extraction of a toothbrush from the esophagus endoscopically without any complications.

Cystic Lymphangioma of the Mesentery in an Adult: A Case Report and Literature Review

Lymphangiomas are rare benign cystic tumors. Surgical excision is the primary treatment, aiming for complete removal. Diagnosis relies on imaging and histological confirmation. Malignant transformation is exceptionally rare. We report a 25-year-old man admitted for peri-umbilical abdominal pain and an abdominal mass. Imaging revealed multilocular peritoneal cystic formations with infiltration of adjacent mesenteric fat. Laboratory findings were unremarkable, and exploratory laparotomy was performed. A voluminous cystic mass originating from the mesentery was discovered, requiring intestinal sacrifice for complete resection. Immediate postoperative recovery was smooth. Pathological analysis confirmed the diagnosis of mesenteric cystic lymphangioma. The patient had a favorable outcome with no tumor recurrence at a three-year follow-up. We emphasize the significance of complete surgical removal to prevent complications associated with cystic lymphangioma and reduce the risk of recurrence.

Approach to Acute Traumatic and Nontraumatic Diaphragmatic Abnormalities

Acute diaphragmatic abnormalities encompass a broad variety of relatively uncommon and underdiagnosed pathologic conditions, which can be subdivided into nontraumatic and traumatic entities. Nontraumatic abnormalities range from congenital hernia to spontaneous rupture, endometriosis-related disease, infection, paralysis, eventration, and thoracoabdominal fistula. Traumatic abnormalities comprise both blunt and penetrating injuries. Given the role of the diaphragm as the primary inspiratory muscle and the boundary dividing the thoracic and abdominal cavities, compromise to its integrity can yield devastating consequences. Yet, diagnosis can prove challenging, as symptoms may be vague and findings subtle. Imaging plays an essential role in investigation. Radiography is commonly used in emergency evaluation of a patient with a suspected thoracoabdominal process and may reveal evidence of diaphragmatic compromise, such as abdominal contents herniated into the thoracic cavity. CT is often superior, in particular when evaluating a trauma patient, as it allows rapid and more detailed evaluation and localization of pathologic conditions. Additional modalities including US, MRI, and scintigraphy may be required, depending on the clinical context. Developing a strong understanding of the acute pathologic conditions affecting the diaphragm and their characteristic imaging findings aids in efficient and accurate diagnosis. Additionally, understanding the appearance of diaphragmatic anatomy at imaging helps in differentiating acute pathologic conditions from normal variations. Ultimately, this knowledge guides management, which depends on the underlying cause, location, and severity of the abnormality, as well as patient factors. ©RSNA, 2024 Supplemental material is available for this article.

Post-liver transplant biliary complications

Biliary complications (BCs) are the most frequent complications following liver transplantation (LT). They are a major source of morbidity after LT. The incidence of BCs after LT is reported to range from 5% to 45%. The main post-LT biliary complications are strictures, biliary fistulas and bilomas, cholelithiasis, sphincter of Oddi dysfunction, hemobilia, and mucocele. Risk factors for biliary complications are diverse. In this article we seek to review the main types of biliary complications and modern approaches to their diagnosis and treatment.

Mesenteric and omental lymphatic malformations in children: seven-year surgical experience from two centers in China

PURPOSE

To compare the clinical characteristics, surgical management and prognosis of mesenteric lymphatic malformations (ML) and omental lymphatic malformations (OL) in children.

METHODS

This retrospective study included 148 ML patients and 53 OL patients who underwent surgical treatment at two centers between January 2016 and December 2022. Details about the patients' clinical characteristics, cyst characteristics, preoperative complications, surgical methods, and prognosis were retrieved and compared.

RESULTS

No significant differences in sex ratio, prenatal diagnosis, or age of diagnosis were noted between ML and OL patients. Vomiting was more common in ML patients than in OL patients (46.6% vs. 22.6%, P = 0.002), but OL patients were more likely to be misdiagnosed (35.8% vs. 18.9%, P = 0.012). The size of the cysts in OL patients was significantly larger than that in ML patients (14.0 [4.0-30.0] vs. 10.0 [2.0-50.0] cm, P<0.001), and cysts with turbid fluid were more common in OL patients (38.0% vs. 20.6%, P<0.001). More OL patients than ML patients had preoperative hemorrhage or infection of cysts (41.5% vs. 31.8%, P<0.016). Cyst excision was performed in 137 (92.6%) ML patients and 51 (96.2%) OL patients, and the incidence of postoperative complications was lower (12.6% vs. 4.2%, P = 0.165) among OL patients. The main postoperative complications included adhesive ileus and recurrence of cysts. Additionally, more OL patients than ML patients were treated with laparoscopic surgery (69.8% vs. 39.2%, P<0.001).

CONCLUSIONS

There were differences in clinical characteristics, cyst characteristics and preoperative complications between ML and OL patients. Cyst excision was the most common surgical method that was used to treat both ML and OL patients, and laparoscopic surgery could be a feasible surgical approach for treating OL patients with a good prognosis.

Combined laparoscopic and thoracoscopic repair of adult right-sided Bochdalek hernia with massive liver prolapse: A case report

BACKGROUND

A Bochdalek hernia (BH) is a congenital diaphragmatic hernia that often develops in the neonatal period. BH typically occurs on the left side of the diaphragm. A right-sided BH in an adult is rare.

CASE SUMMARY

A 45-year-old man was referred to our hospital because of an abnormal shadow seen on chest radiography during a medical check-up. A chest radiograph showed elevation of the right hemidiaphragm. Computed tomography showed prolapse of multiple intraabdominal organs into the right thoracic cavity, corresponding to a right-sided BH. The herniated contents included the stomach, transverse colon, and left lobe of the liver. The left lobe of the liver was enlarged, particularly the medial segment. Laparoscopic surgery was performed. However, the left lobe of the liver was completely trapped in the thoracic cavity. Therefore, thoracoscopic manipulation had to be performed to return the liver to the abdominal cavity. The hernia was repaired with interrupted nonabsorbable sutures and reinforced with mesh.

CONCLUSION

Combined laparoscopic and thoracoscopic surgery was successfully performed for right-sided BH with massive liver prolapse and abnormal liver morphology.

Congenital Hernias in Adults: Bochdalek Hernias

Bochdalek hernias are a rare occurrence in adults and usually asymptomatic, resulting in incidental discovery. However, surgical intervention is recommended for both symptomatic and asymptomatic Bochdalek hernias due to the risk of acute morbidity and mortality. There are various possible surgical approaches that may be appropriate depending on the circumstance, with robotic repair becoming increasingly popular. To date, the rarity of the condition has limited the available data on postoperative outcomes.

Recurrent skin opening induced by chronic sternal osteomyelitis caused by a bite wound in a cat: A case report

BACKGROUND

Chronic sternal osteomyelitis is a rare condition in felines, with limited reported cases to date.

OBJECTIVES

We report the case of a 2-year-old castrated male, domestic shorthair cat, weighing 4.68 kg, that presented with skin openings every 3-4 months, despite skin debridement and reconstruction.

METHODS

A subcutaneous dead space larger than the skin defect was detected. Haematological analysis revealed elevated levels of inflammatory markers. Thoracic radiography revealed sternal deformation and suspected osteomyelitis. Computed tomography revealed a fistula extending from the third to the fourth sternebrae.

RESULTS

Bone and soft tissue debridement and abscess flushing were performed along with long-term antibiotic therapy. The cat remained recurrence-free throughout an 18-month post-surgery follow-up period.

CONCLUSION

To the best of our knowledge, this is the first report of chronic osteomyelitis occurring in a cat's sternebrae and represents the first successful case of its treatment. This case showcases the potential for improved treatment outcomes in similar cases. Understanding and successful treatment of such cases can pave the way for better management of feline osteomyelitis.

Amyand's hernia with concurrent appendicitis: A case of interval laparoscopic herniorrhaphy and literature review

INTRODUCTION AND IMPORTANCE

Amyand's hernia with concurrent appendicitis is rare, with a reported incidence of 0.13 % of all inguinal hernias. This condition is challenging to diagnose and manage and no optimal treatment has been established.

CASE PRESENTATION

A 71-year-old man presented with an acutely painful, tender, and irreducible right inguinal hernia. He had a history of a right inguinal hernia for several months and had undergone open left inguinal hernia repair. The patient had no other medical comorbidities. Blood test results were nonspecific, with a C-reactive protein of 90 mg/L. Ultrasound scan suggested a strangulated right inguinal hernia. Laparoscopy revealed an Amyand's hernia with concurrent appendicitis and a pus-filled right inguinal hernia sac. The patient underwent laparoscopic appendicectomy, followed by staged laparoscopic transabdominal preperitoneal right inguinal hernia repair with mesh after eight weeks to reduce mesh infection. Histopathological examination confirmed acute uncomplicated appendicitis without perforation or malignancy. The patient had an unremarkable post-operative recovery.

DISCUSSION

This case highlights the diagnostic challenges associated with Amyand's hernia and concurrent appendicitis. Laparoscopy provides both diagnostic and therapeutic opportunities. In this case, laparoscopic mesh herniorrhaphy was delayed and staged until local hernia sac inflammation resolved following appendicectomy.

CONCLUSION

Surgeons should have an index of suspicion for Amyand's hernia given the heterogeneity of presentations. A case-by-case approach is required to prevent post-operative complications and determine the safe timing of definitive hernia repair when the inguinal hernial sac is inflamed. Further research is required to provide surgeons with evidence-based approaches for this unique condition.

Right-Sided Ectopic Intrathoracic Kidney Associated With Symptomatic Bochdalek Hernia in an Adult Indian Female: Case Report and Review of Literature

Bochdalek hernia is an inherited posterior lateral defect in the diaphragm that allows the abdominal organs to herniate into the thoracic cavity. In addition to being the most prevalent variety of congenital diaphragmatic hernia (CDH), it is also the type that is observed on the left hemithorax the majority of the time. Ectopic kidney is an uncommon condition, and the occurrence of ectopic intrathoracic kidney is even more uncommon, accounting for only a few of all the cases of renal ectopias. The occurrence of intrathoracic kidney associated with Bochdalek hernia is infrequent among adult individuals and is typically an incidental finding. A 52-year-old obese female patient presented to the pulmonology outpatient unit and reported experiencing the symptoms of coughing, wheezing, and difficulty in breathing since three years. A chest radiograph revealed an elevated dome of the diaphragm on the right side. A computed tomography (CT) of the chest revealed a defect in the posterior aspect of the right hemi-diaphragm with herniation of the right kidney and retroperitoneal fat into the right hemi-thorax. CT urography showed normal size and enhancement of the intrathoracic kidney with prompt excretion of contrast into the pelvicalyceal system. With regard to the small size of the hernia and considering the absence of complications on CT urography, a conservative treatment was proposed to the patient. The patient was followed up every year. There was no occurrence of renal complications during the follow-up period. When evaluating patients with 'elevated hemi-diaphragm' or thoracic 'mass', it is essential to check for the presence of intrathoracic kidney to avoid undesirable surgical procedures and image-guided biopsies.

Splenic hamartomas in children

Splenic hamartomas (SHs) are uncommon, benign vascular lesions of unclear etiology and are mostly found incidentally on abdominal images, at surgery, or at autopsy. Since the first case description, in 1861, less than 50 pediatric SH cases have been reported in the literature. In this article, we have performed an analysis of all SH cases in children published in the literature to date and presented our case of an 8-year-old male with SH. These lesions in children were shown to cause symptoms more often than in the adult population. The observed SH sizes in children ranged from a few millimeters to 18 cm, and the symptomatic lesions were mostly larger or multiple. The most common clinical finding was splenomegaly. Signs of hypersplenism were present in children with a single SH larger than 4.5 cm (diameter range: 4.5-18.0 cm) and in those with multiple hamartomas, ranging from a few millimeters to 5 cm. Eighty percent of patients with available laboratory findings had hematological abnormalities such as anemia, thrombocytopenia, or pancytopenia. Other symptoms and signs included abdominal pain, recurrent infections, fever, night sweats, lethargy, growth retardation, and weight loss. The use of multiple imaging modalities may suggest the preoperative diagnosis of a splenic mass in children and determine the therapeutic approach. However, the final diagnosis of SH relies on histopathological evaluation. Surgery, including total or partial splenectomy (PS), is the mainstay of SH management. Although total splenectomy carries a greater risk of overwhelming post-splenectomy infection than PS it has remained the most performed surgical procedure in children with SH. In the majority of pediatric patients with symptomatic SH, resolution of symptoms and resolution or improvement of cytopenias occurred after surgical treatment.

Endoscopic management of ingested toothpick resulting in duodeno-ureteric fistula

Toothpicks are commonly used but rarely ingested. Unlike most foreign bodies, if accidentally swallowed these rarely spontaneously pass. The duodenum has been reported as the most common site of toothpick foreign body lodgement in the upper gastrointestinal tract. We report the case of a 57-year-old presenting with recurrent urosepsis after non recognition of a toothpick impaction in the duodenum with fistulisation into the right renal pelvis. Endoscopic removal of the foreign body was successful in management of the urosepsis.

The Transaxillary Approach as a Direct Route in the Management of Upper Thoracic Spine Pathology: A Technical Note with Case Series

This retrospective case series of prospective data aims to describe the transaxillary approach for the treatment of upper thoracic spine pathology. Various surgical techniques and approaches have been reported across the literature to address upper thoracic spine pathology, including the cervicothoracic approach, anterior transsternal approach, posterolateral approach, supraclavicular approach, and lateral parascapular approaches. These techniques are invasive. A minimally invasive, less morbid, and direct access approach to the pathology of the upper thoracic spine has not been reported in the literature. Patients with pathology affecting the first thoracic vertebra up to the sixth thoracic vertebra were classified into the upper thoracic spine group. Patients with pathology below the sixth thoracic vertebra were excluded. Patients not having a minimum follow-up of 12 months were also excluded. The study analyzed 18 patients. The mean preoperative modified Japanese Orthopedic Association score was 7.2±1.44, which improved to 10.16±1.2 (p<0.05). The majority (14/18) of the patients had an excellent outcome. Three patients had good outcomes, and one patient had a fair outcome. Five cases of intraoperative dural leak were recorded, and one patient had postoperative neurological deficit. The transaxillary approach is a safe, viable, muscle-sparing, and minimally invasive approach for ventral pathologies of the upper thoracic spine.

Spigelian hernia: a multi-site review of operative outcomes of surgical repair in the adult population

PURPOSE

Spigelian hernias arise at the linear semilunaris and account for approximately 1-2% of abdominal hernias. The aetiology is due to a defect of the aponeurosis of the transverse abdominis and when discovered, management is surgical intervention. The aim of this study was to observe operative outcomes for open and minimally invasive repair.

METHODS

A retrospective chart review was conducted at two hospitals in Townsville, The Townsville University Hospital and The Mater Private Hospital over a 10-year period (2010 to 2020). A surgical database search (ORMIS & IEMR) was performed at both locations using key search terms, including "spigelian hernia", "laparoscopic", "open". Descriptive statistics were utilised to analyse patient factors and operative outcomes in the public and private setting.

RESULTS

43 cases of Spigelian hernias (25 female, 18 male) were reported over the study period. The average age was 66. There were 36 elective cases and 7 emergency cases. A laparoscopic approach was the preferred method of repair, occurring in 74% of cases. Of these cases, the predominant hernial content was fat only. 65% of cases had a history of prior abdominal surgery unrelated to the "Spigelian belt" location. Complications occurred in 19% of cases. Other variables, such as ethnicity, smoking status, defect size, predisposing factors and recurrence rate, were analysed and did not yield statistical significance.

CONCLUSION

Although a small sample size, the data suggest there is no statistically significant difference between operative outcomes, complication rate and predisposing factors between open and minimally invasive case groups.

Free Flap Reconstruction of Sternal Defects after Cardiac Surgery: An Algorithmic Approach for Dealing with Sparse Recipient Vessels

Background

Sparsity of recipient vessels poses a challenge for microsurgical free flap reconstruction of sternal defects following deep sternal wound infection after cardiac surgery.

Methods

From January 2013, a standardized algorithm for dealing with sparse recipient vessels was strictly followed. In this retrospective study including 75 patients, we compared operative details, surgical complications, and reconstructive outcomes of patients treated according to this algorithm (group A: January 2013-May 2021; n = 46) with a historical control group (group B: January 2000-December 2012, n = 29).

Results

The left internal mammary artery had been harvested for arterial bypass grafting in 40 of 46 cases (87%) in group A and in all cases in group B. The right internal mammary artery (RIMA) and right internal mammary vein (RIMV) were the first choice as recipient vessels. In case of unsuitability of the RIMV, a right cephalic vein (CV) turndown was used for venous outflow. If both RIMA and RIMV proved insufficient, a single-stage arterio-venous loop (AVL) between the CV and subclavian artery (CV-SA AVL), CV and thoracoacromial artery (CV-TA AVL), or subclavian artery and subclavian vein (SA-SV AVL) was established. The algorithmic approach significantly reduced partial flap necrosis [group A: n = 3 (7%) versus group b: n = 7 (24%); P = 0.04], and overall operation time [group A: 360 ± 88 min versus group B: 415 ± 80 min; P = 0.01].

Conclusions

Standardized approaches improve clinical outcomes in microsurgical free flap sternal reconstruction after cardiac surgery.

A Single-Center Retrospective Study of Re-Transplantation After Allograft Failure in Kidney Transplant Recipients

BACKGROUND

This study aimed to examine the outcomes of kidney retransplantation in patients with allograft failure at Kyushu University.

METHODS

We reviewed data from 1043 consecutive patients (including 1001 in a first kidney transplantation [KT] group and 42 in a second KT group) who had undergone KT alone at our institution between January 2008 and September 2022. We also studied immunologic risks and outcomes of patients who had undergone preoperative testing for KT at Kyushu University during the same period.

RESULTS

No patient received more than 2 transplants. Donor-specific anti-HLA antibody (DSA) had been detected in a greater percentage of patients in the second KT group than in the first (31% vs 11%, respectively; P < .001). There were no significant differences in 5-year death-censored/overall graft survival rates, rates of surgical complications, or incidence of delayed graft function between the groups. During the study period, significantly more candidates for second than first KT were rejected for this procedure because of their high immunologic risk (20% vs 2%, P < 001). Seven of the 42 patients in the second KT group required the removal of the primary graft during the second transplantation.

CONCLUSION

There is a higher percentage of patients whose DSA has been detected among patients undergoing retransplantation after allograft failure than among those receiving first KTs, which often leads to remaining on the waiting list in the former group. However, if the immunologic risk is within acceptable limits, the graft survival for retransplantation is not inferior to that of a first KT.

Rigid Plate Fixation for Closure of Emergent Sternotomies for Trauma

BACKGROUND

No studies to date have evaluated the use of rigid plate fixation for emergent sternotomy in trauma patients. We evaluated our use of rigid plate fixation vs wire cerclage in patients requiring emergent sternotomy. We hypothesized there would be no difference in complications related to sternal closure between the two groups.

METHODS

We performed a retrospective cohort study to include all patients who underwent emergent sternotomy from 1/1/2018 to 1/31/2021 and survived to have their sternum closed. Outcomes in patients closed with wire cerclage group (WC) were compared to patients who underwent rigid plate fixation (RPF).

RESULTS

Twenty-two patients underwent emergent sternotomy. There were 11 patients in each group. There was no significant difference in admission demographics, ISS, or admission characteristics between the two groups. Complication rates related to closure (wound infection and hardware removal) were not significantly different (WC 27% vs RPF 9%, P = .58). Neither hospital length of stay (WC: 29 days vs RPF: 13 days, P = .13), ICU length of stay (WC: 6 days vs RPF: 7 days, P = .62), nor the number of ventilator days (WC: 3 days vs RPF: 1 day, P .11) were statistically different. All patients survived to discharge.

DISCUSSION

This is the first study comparing RPF and WC for sternotomy closure in the setting of trauma. We found no difference in the rate of wound related complications. This study demonstrates the feasibility of rigid plate fixation for trauma sternotomy closure and lays the foundation for future prospective studies.

Idiopathic mesenteric phlebosclerosis occurring in a patient with liver cirrhosis: A case report

BACKGROUND

Idiopathic mesenteric phlebosclerosis (IMP) is a rare gastrointestinal disease with unclear etiology and pathogenesis. IMP occurring in a patient with liver cirrhosis is more scarcely reported than independent IMP. In this study, we reported a case of IMP occurring in a patient with liver cirrhosis, so as to provide a reference for understanding liver cirrhosis with IMP.

METHOD

A 63-year-old man with liver cirrhosis was admitted in the hospital's department of infectious disease because of fatigue and constipation for 1 month. The patient had an irregular medical history of antivirus drug and Chinese herbal medicine intake because of the hepatitis B virus infection. No other abnormalities were found in the functions of the liver, coagulation, renal, or complete blood count. Fecal occult blood tests were all positive in 5 detections. Contrast-enhanced computed tomography revealed liver cirrhosis and showed thickening of the wall of the right hemicolon and multiple calcifications of the mesenteric veins. Mesenteric vein computed tomography venography displayed diffuse colon mural thickening of the right colon and tortuous linear calcification line in the right colic veins. Colonoscopy revealed a purple-blue, swollen, rough, and vanished vascular texture mucosa. He was finically diagnosed as liver cirrhosis with IMP by a series of examinations during hospitalization.

RESULTS

His symptoms of fatigue and constipation subsided after conservative treatment and withdraw from Chinese herbal medicine. The patient experienced no obvious discomfort during the follow-up period.

CONCLUSION

A comprehensive medical diagnosis is necessary for the discovery of IMP, especially IMP with liver cirrhosis. Liver cirrhosis maybe play a key role in the development of IMP. The regulatory mechanism of liver cirrhosis contributing to IMP needs to be further studied based on more clinical cases.

Hangeshashinto-Associated Mesenteric Phlebosclerosis and Highly Atypical Adenoma Requiring Laparoscopic Right Hemicolectomy

Mesenteric phlebosclerosis is a rare ischemic colonic disorder caused by impaired venous drainage. Its prevalence is higher in East Asia, where herbal medicine is widely used. Treatment remains controversial. A 76-year-old woman who had taken Hangeshashinto, an herbal medicine, for 11 years was admitted for endoscopic treatment of high-grade dysplasia in the ascending colon. She had diarrhea and mesenteric phlebosclerosis diagnosed by abdominal computed tomography at age 71. At age 75, small polyps were detected in the ascending colon. A subsequent study revealed an increase in polyp size to 15 mm. Endoscopic mucosal resection failed to remove the lesion. A biopsy showed high-grade dysplasia with possible colon cancer risk. Conservative therapy did not improve mesenteric phlebosclerosis-related diarrhea; therefore, a laparoscopic right hemicolectomy was performed. Intraoperatively, the cecum was adherent to the abdominal wall and the right ovary. The specimen showed high-grade dysplasia in the mucosa and severe submucosal fibrosis. No metastasis was observed. This case shows the link between mesenteric phlebosclerosis and high-grade dysplasia in the ascending colon. Endoscopic mucosal resection was unsuccessful in removing the tumor. Endoscopic submucosal dissection was an alternative, but its safety in mesenteric phlebosclerosis-affected colonic segments remains uncertain. A laparoscopic right hemicolectomy was performed.

Long-term outcomes of liver transplantation for biliary atresia and results of policy changes: over 20 years of follow-up experience

Objective

Biliary atresia (BA) patients develop chronic liver disease after the Kasai operation and are eventually indicated for liver transplantation (LT). The purposes of this study were to analyze long-term outcomes after LT and risk factors that affect complications to reduce graft failure.

Study design

Overall, 145 pediatric patients who underwent LT between June 1996 and June 2020 after a diagnosis of BA were included. We performed a retrospective analysis of medical records and evaluated patient and graft survival, cumulative incidence of complications, risk factors, and the results of policy changes.

Results

Patient and graft survival rates in over 20 years were 95.8% and 91.0%, respectively. Post-transplantation lymphoproliferative disease was frequently observed in the early period of immunosuppression within the first 1-2 years after LT. The incidence of cholangitis and rejection steadily increased over time. Weight-to-portal vein size was evaluated as a risk factor for cholangitis and bile duct strictures (OR = 12.82, p = 0.006 and OR = 16.54, p = 0.015, respectively). When evaluated using 2013 as a reference point, the split graft indication was expanded and the group that received LT after 2013 had a significantly lower survival over time compared with that of the group that received LT before 2013 (p = 0.006).

Conclusion

This study revealed time differences in prevalence of complications. The evaluation of weight-to-duct or vessel size is a more important factor in considering complications than the graft-to-recipient weight ratio. Survival outcomes may have been altered by a policy change that affects the donor type ratio in transplantation.

Clinical significance of abdominal computed tomography and colonoscopy in the evaluation of phlebosclerotic colitis

Clinical manifestations of phlebosclerotic colitis (PC) exhibit significant variability, necessitating diverse treatment strategies depending on disease severity. However, there is limited research exploring the relationship between imaging findings and disease severity. Hence, this retrospective study aimed to analyze the correlation between computed tomography (CT) findings, colonoscopic features, and disease severity. This study compared the abdominal CT characteristics, colonoscopy findings, and treatment modalities of 45 PC patients. CT images were assessed for the severity of mesenteric venous calcification, maximum colonic wall thickness, number of involved colonic segments, and presence of pericolic inflammation. Colonoscopic images were assessed for dark purple discoloration mucosa, erosive and ulcerative lesions, mucosal edema, luminal narrowing, and the number of involved colonic segments. In addition, patients were categorized into three groups: the observation (n = 15), medical treatment (n = 19), and operation (n = 11) groups. In CT images, a significant difference in pericolic inflammation (p = 0.039) was observed among groups. Further, significant differences in dark purple discoloration mucosa (p = 0.033), erosive or ulcerative lesions (p < 0.001), mucosal edema (p < 0.001), luminal narrowing (p = 0.012), and the number of involved colonic segments (p = 0.001) were observed in colonoscopy. Moreover, we found positive correlations between CT and colonoscopy features. In conclusion, CT manifestations and colonoscopy findings exhibited correlation with disease severity in PC. When limited to one diagnostic tool, observations from that tool can infer potential manifestations of the alternative tool.

Amyand's Hernia: A Rare Case Study of Perforated Appendicitis in an Inguinal Hernia

Amyand's hernia is defined as the presence of an appendix contained within an inguinal hernia. An inguinal hernia is the protrusion of a small or large bowel through a peritoneal defect of the groin. In rare cases, the appendix can become incarcerated or strangulated within the hernia, cutting off the blood supply to the organ. If incarcerated, the appendix is at risk for strangulation, which can lead to rupture and cause worsening of symptoms and/or collapse. We report a case of a 76-year-old male with a history of inguinal hernia repair 30 years prior, who presented with 30 days of intermittent right lower quadrant pain and unintentional weight loss. He required emergent treatment and management. This case underscores the challenge of diagnosing concurrent inguinal hernia and appendicitis and places an emphasis on timely intervention. Treatment options vary based on the appendix's apparent condition within the hernia sac. Despite the complications, including additional drainage site and enterocutaneous fistula, the patient was discharged in stable condition. This case contributes insights into managing complex inguinal pathologies, particularly in the geriatric population.

Technical Variant Liver Transplant Utilization for Pediatric Recipients: Equal Graft Survival to Whole Liver Transplants and Promotion of Timely Transplantation Only When Performed at High-volume Centers

BACKGROUND

Technical variant liver transplantation (TVLT) is a strategy to mitigate persistent pediatric waitlist mortality in the United States, although its implementation remains stagnant. This study investigated the relationship between TVLT utilization, transplant center volume, and graft survival.

METHODS

Pediatric liver transplant recipients from 2010 to 2020 (n = 5208) were analyzed using the Scientific Registry of Transplant Recipients database. Transplant centers were categorized according to the average number of pediatric liver transplants performed per year (high-volume, ≥5; low-volume, <5). Graft survival rates were compared using Kaplan-Meier curves and log-rank tests. Cox proportional hazards models were used to identify predictors of graft failure.

RESULTS

High-volume centers demonstrated equivalent whole liver transplant and TVLT graft survival ( P = 0.057) and significantly improved TVLT graft survival compared with low-volume centers ( P < 0.001). Transplantation at a low-volume center was significantly associated with graft failure (adjusted hazard ratio, 1.6; 95% confidence interval, 1.14-2.24; P = 0.007 in patients <12 y old and 1.8; 95% confidence interval, 1.13-2.87; P = 0.013 in patients ≥12 y old). A subset of high-volume centers with a significantly higher rate of TVLT use demonstrated a 23% reduction in waitlist mortality.

CONCLUSIONS

Prompt transplantation with increased TVLT utilization at high-volume centers may reduce pediatric waitlist mortality without compromising graft survival.

Amyand's Hernia With Sliding Component: A Case Report

Amyand's hernia (AH) occurs when the appendix becomes part of an inguinal hernia. Amyand's hernias are typically discovered incidentally during surgery due to their variable clinical manifestations and features, such as caecum and appendix forming the sliding component in the present case. Claudius Amyand operated it for the first time in 1735. Due to the simple presentations that these patients typically exhibit, the diagnosis is extremely challenging. The choice between surgical modalities is influenced by the numerous, logically accepted advantages and disadvantages of management modalities, which are subject to debate. That being said, we believe that, in the absence of sepsis or inflammation, open repair using mesh - as long as a clean operating room and competent surgical skill are available - should be the gold standard approach.

Endoscopic Removal and Conservative Treatment of a Small Bowel Perforation Caused by a Toothpick: A Case Report

This case report describes a unique instance of small bowel perforation in a 49-year-old woman caused by an ingested toothpick. Initially suspected of colonic diverticulitis, a final diagnosis of small bowel perforation was made later, and the toothpick was successfully removed via endoscopy. This case emphasizes the need to consider foreign body ingestion in the differential diagnosis of abdominal pain and demonstrates the feasibility of conservative endoscopic approaches in similar cases.

Recurrent Ureterosciatic Herniation Causing Right Obstructive Uropathy

Sciatic hernias are unusual, challenging to diagnose, and can present some treatment dilemmas. Sciatic hernias containing the ureter are even less common. Symptoms are variable from renal fossa pain, mild or severe pelvic pain, neuropathic pain, or dysesthesias. Although stenting alone can be a treatment option for this condition, in cases where symptoms or ureteral obstruction relapse after initial treatment, sciatic hernioplasty must be considered as the definitive treatment. This article presents the case of a female patient who presented with a history of nonspecific abdominal pain and was diagnosed with a right-sided ureterosciatic hernia. This was managed with a ureteral stent for reduction of herniated ureteral content, but after recurrence, laparoscopic sciatic hernioplasty was performed. The patient was pain-free and without obstructive uropathy at the one-year follow-up.

Postoperative abdominal herpes zoster complicated by intestinal obstruction: A case report

BACKGROUND

Intestinal obstruction is a common occurrence in clinical practice. However, the occurrence of herpes zoster complicated by intestinal obstruction after abdominal surgery is exceedingly rare. In the diagnostic and treatment process, clinicians consider it crucial to identify the primary causes of its occurrence to ensure effective treatment and avoiding misdiagnosis.

CASE SUMMARY

Herein, we present the case of a 40-year-old female patient with intestinal obstruction who underwent laparoscopic appendectomy and developed herpes zoster after surgery. Combining the patient's clinical manifestations and relevant laboratory tests, it was suggested that the varicella zoster virus reactivated during the latent period after abdominal surgery, causing herpes zoster. Subsequently, the herpes virus invaded the visceral nerve fibers, causing gastrointestinal dysfunction and loss of intestinal peristalsis, which eventually led to intestinal obstruction. The patient was successfully treated through conservative treatment and antiviral therapy and subsequently discharged from the hospital.

CONCLUSION

Pseudo-intestinal obstruction secondary to herpes zoster infection is difficult to distinguish from mechanical intestinal obstruction owing to various causes. In cases of inexplicable intestinal obstructions, considering the possibility of a viral infection is essential to minimize misdiagnosis and missed diagnoses.

Adult Mesenteric Lymphangioma Resulting in Small Bowel Obstruction

A mesenteric cystic lymphangioma (MCL) is a rare condition that primarily manifests in children. This case report illustrates an unusual presentation of an MCL causing a small bowel obstruction with volvulus in an adult. We present a 31-year-old male who presented to our hospital with a small bowel obstruction. He underwent laparotomy, and a lymphatic mass acting as a lead point and causing small bowel volvulus was discovered intra-operatively. The patient underwent a small bowel with associated mass resection and primary anastomosis; he recovered well. The final pathology demonstrated an MCL. Despite the MCL being a rare entity in adults, it must be considered as the differential for various abdominal pathologies. Although the majority of these masses lack malignant potential, they should be resected, as they pose a risk of mechanical obstruction, torsion, and perforation. Prior descriptions include individual case reports of symptomatic lesions, proposed non-operative management, and follow-up imaging.

Robotic thoracoabdominal hernia repair: a novel approach

PURPOSE

Thoracoabdominal hernias remain a rare and poorly understood entity. Data remain sparse as terminology varies in the literature and case reports demonstrate wide variability in technique. We present a novel approach for repair of thoracoabdominal hernias using the robotic platform.

METHODS

Two patients underwent a robotic thoracoabdominal hernia repair in June 2022. They were followed for 1 year with CT scans every 6 months to exclude recurrence. Patient demographics and peri-operative details including defect size, closure technique, mesh size, length of stay, and complications were reported.

RESULTS

Both patients successfully underwent a robotic repair of a thoracoabdominal hernia, addressing the intercostal hernia, diaphragmatic disruption, and flank hernia discretely during the operation. One patient had an uneventful recovery and discharged on post-operative day 3; the other developed a small bowel obstruction due to an early port site hernia which required surgical intervention. He eventually discharged on post-operative day 9. At one year, there is no clinical or radiographic evidence of recurrence for either patient.

CONCLUSION

Robotic thoracoabdominal hernia repair is feasible and offers a minimally invasive repair option for these extremely complex hernias.

Amyand's Hernia: Incarcerated Appendicitis in a Recurrent Inguinal Hernia in an Adult

Inguinal hernias are among the most common cases presented to a surgeon. In spite of extensive research and clinical experience over centuries, inguinal hernias still pose anatomical challenges for operating surgeons, especially with a propensity for recurrence. One such complicated entity is the Amyand's hernia - defined as an inguinal hernia contained within the hernial sac - the vermiform appendix - as the herniated content. It is a rare clinical presentation and carries with it certain complexities with regard to operative decisions and clinical management. We present a case of a 71-year-old male presenting with a recurrent inguinal hernia, with an incarcerated, inflamed appendix as the content; managed surgically with appendicectomy and herniorraphy, without the use of a prosthetic mesh.
