The spleen is a very hostile environment for tumor cells due to its anatomic location, blood supply, and rich immunological property – which makes it one of the most unique organ to be involved in metastatic diseases.15 Splenic metastases from non-hematologic malignancies are rare ranging from 0.6 to 7.1% base on autopsy reports of cancer patients, and 1.1 to 3.4% base on review of splenectomy cases.14 Moreover, isolated splenic metastases are more infrequent with only 31 cases reported from 1969 to October 2015.16 A splenic abscess is an unusual formation and is usually caused by hematogenous spread from an infection. Such expected frequency varies in different autopsy studies between 0.14% and 0.7%.1 Albeit rare, abscess can also result from migration of gut flora brought about by direct invasion of tumor cells from a neighboring neoplasm.17 This is a case of a 36-year-old female who came in with a history of abdominal pain, chills and fever for seven months. CT scan of the whole abdomen revealed splenic abscess with suspicion of a splenic rupture. The patient underwent exploratory laparotomy with abscess evacuation, splenectomy and double barrel colostomy and given with intravenous antibiotics. Histopathology results showed metastatic adenocarcinoma in the spleen. Thorough deliberation of her case was done and she was eventually managed as a case of Colon Cancer Stage IV and underwent chemotherapy. Splenic abscess developing from splenic metastasis from a colonic adenocarcinoma is rare and with concomitant high mortality rate. More often than not, splenic metastasis is discovered in advanced stage together with metastatic tumor in other organs while isolated splenic metastasis is even more uncommon. A splenic abscess as an initial demonstration of a colon cancer is not a common daily encounter of physicians hence a high index of suspicion coupled with sensitive and specific imaging is necessary in order to provide prompt medical and surgical intervention.

Omental torsion is a rare cause of acute surgical abdomen from omental twisting leading to distal vascular compromise. Preoperative diagnosis has been a dilemma as clinical features, laboratory and radiographic findings are nonspecific and variable, closely mimicking acute appendicitis. Surgical excision has been suggested to offer rapid symptom relief and postoperative recovery. Presented here is a case of a 59-year-old male with omental torsion who presented with generalized abdominal tenderness and was preoperatively diagnosed as ruptured appendicitis who underwent laparotomy with uneventful post-operative course.

Gliomatosis peritonei (GP) is a condition characterized by the dissemination of mature glial tissues throughout the peritoneal cavity. It is usually associated with immature ovarian teratoma but presents with mature cystic teratoma (MCT) in 1% of cases. GP, associated with MCT, is a benign disorder. The majority of cases remain asymptomatic and rarely recur. Here, we present a case of a 22-year-old woman with a history of abdominal enlargement and severe abdominal pain who underwent exploratory laparotomy, peritoneal fluid cytology, bilateral salpingo-oophorectomy, appendectomy, omental biopsy, and Jackson-Pratt drain insertion with histopathologic result of GP with MCT. A month later, the patient had a recurrence of abdominal enlargement, necessitating a second surgery. Immunohistochemistry for histopathologic evaluation and diagnostic imaging are crucial in confirming the diagnosis and guiding the treatment strategy. A multidisciplinary team approach in monitoring and comprehensive support is significant in optimizing outcomes for patients with aggressive GPs associated with MCT. Further research and clinical experience are essential to establish a standardized guideline to improve the management and clinical outcome of this condition.

This study aims to develop an abdominal acupoint localization system based on computer vision and convolutional neural networks (CNNs). To address the challenge of abdominal acupoint localization, a multi-task CNNs architecture was constructed and trained to locate the Shenque (CV8) and human body boundaries. Based on the identified Shenque (CV8), the system further deduces key characteristics of four acupoints: Shangwan (CV13), Qugu (CV2), and bilateral Daheng (SP15). An affine transformation matrix is applied to accurately map image coordinates to an acupoint template space, achieving precise localization of abdominal acupoints. Testing has verified that this system can accurately identify and locate abdominal acupoints in images. The development of this localization system provides technical support for TCM remote education, diagnostic assistance, and advanced TCM equipment, such as intelligent acupuncture robots, facilitating the standardization and intelligent advancement of acupuncture.

Wunderlich Syndrome is a rare potentially life-threatening phenomenon that involves spontaneous non-traumatic retroperitoneal hemorrhage. At present, identifying the course of conservative management in these patients, especially in pregnancy, has not been clinically established. Presented here is a known case of Tuberous Sclerosis Complex with a Bilateral, 10cm Angiomyolipoma in a 31-year-old female, initially managed with active surveillance. At 27 weeks of pregnancy, she presented with a sudden onset of left flank pain with a hematocrit of 22%. Anemia was corrected with blood transfusions. A contrast-enhanced MRI of the abdomen showed a large subcapsular perirenal hematoma of the left kidney. Renal angioembolization of the bleeding segmental renal artery was done. The patient was conservatized until 37 weeks of pregnancy and underwent cesarean section delivery.

Four months after angioembolization, she had a recurrence of the left flank pain associated with gross hematuria and hypovolemic shock. The patient underwent emergency renal exploration of the left kidney via a transabdominal approach. Three liters of hemoperitoneum and a large expanding left retroperitoneal hematoma were noted intraoperatively. Early vascular control before nephrectomy of the left kidney was done. The postoperative course was unremarkable and the patient was discharged with improved condition.

This case displays a unique course in the management of a bleeding angiomyolipoma especially during pregnancy. Renal angioembolization can aid in achieving the age of viability in pregnancy. However, close monitoring for rebleeding should be kept in mind. A lower threshold for conservative management should be utilized when patients have a previous history of bleeding.

Endometriosis is defined as the presence and growth of the glands and stroma of the lining of the uterus in an aberrant or heterotopic location. The cause of endometriosis is uncertain and involves many mechanisms including retrograde menstruation, vascular dissemination, metaplasia, immunologic, and hormonal influences to name a few. Primary umbilical endometriosis is a rare disorder defined as the presence of ectopic endometrial tissue within the umbilicus. It commonly presents with catamenial pain and bleeding from an umbilical nodule. It is a rare condition and treatment has not been standardized yet due to the limited number of cases. Surgical management is the treatment of choice to avoid local recurrence while hormone therapy may be used preoperatively for symptomatic relief. This paper reports a series of recently observed cases of primary umbilical endometriosis with main aim of discussing the different approaches in the management of this rare condition.

OBJECTIVE: To explore the effectiveness of free paraumbilical perforator flaps in repairing skin and soft tissue defects in children. METHODS: Between February 2018 and March 2024, 12 children with skin and soft tissue defects were treated with the free paraumbilical perforator flaps. There were 7 boys and 5 girls with an average age of 6.3 years (range, 2-12 years). The defects located on the upper limbs in 6 cases, lower limbs in 5 cases, and neck in 1 case. The causes of wounds included 7 cases of electrical burns, 1 case of thermal burn, 2 cases of scar release and excision due to scar contraction after burns, 1 case of scar ulcer at the amputation stump after severe burns, and 1 case of skin necrosis after a traffic accident injury. The size of defects after debridement ranged from 7.0 cm×4.0 cm to 18.0 cm×10.0 cm. According to the defect size, 11 cases were repaired with unilateral paraumbilical perforator flaps centered on the umbilicus, among which 3 cases with larger defects were designed as "L"-shaped flaps along the lateral and lower ends of the perforator; the donor sites were directly closed. One case with extensive defect after scar excision and release was repaired with bilateral expanded paraumbilical perforator flaps; the donor sites were repaired with autologous split-thickness skin grafts. The size of flaps ranged from 9.0 cm×4.0 cm to 20.0 cm×11.0 cm. Postoperatively, analgesia and sedation were provided, and the blood supply of the flaps was observed. RESULTS: All operations were successfully completed. The operation time was 4-7 hours, with an average of 5.0 hours. After postoperative analgesia and sedation, the visual analogue scale (VAS) score for pain in all children was less than or equal to 3, and there was no non-cooperation due to pain. All flaps and skin grafts survived completely, and the wounds healed by first intention. Ten children underwent 1-4 times of flap de-fatting, finger separation, and trimming. All children were followed up 6-48 months (mean, 26.6 months). No obvious swelling of the flaps occurred, and the texture was soft. At last follow-up, among the 6 children with upper limb defects, 2 had upper limb function grade Ⅳ and 4 had upper limb function grade Ⅴ according to the Carroll upper limb function assessment method. The 4 children with lower limb defects had no limitation of joint movement. The neck flexion and rotation in the 1 child with neck defect significantly improved when compared with that before operation. The 1 child with residual ulcer at the amputation stump could wear a prosthesis and move without limitation, and no new ulcer occurred. Linear scars were left at the donor sites, and no abdominal wall hernia was formed. CONCLUSION The free paraumbilical perforator flap has abundant blood supply and can be harvested in large size. It can be used to repair skin and soft tissue defects in children and has the advantages of short operation time, minimal injury, high safety, and minimal impact on the growth and development of children.

Eosinophilic gastroenteritis (EGE) is a gastrointestinal disorder of unclear etiology that is characterized by eosinophilic infiltration of the stomach and small intestine, and consists of mucosal, muscular, and serosal subtypes. Eosinophilic infiltration of the gastrointestinal tract is a fundamental histopathological characteristic of EGE and is driven by several T-helper type 2 (Th2)-dependent cytokines and induced by food allergy. Due to the lack of a diagnostic gold standard, EGE has a high rate of delayed diagnosis or misdiagnosis. However, several new diagnostic strategies have been developed, such as novel genetic biomarkers and imaging tests. Although dietary therapy and corticosteroids remain the common choices for EGE treatment, recent decades have seen the emergence of novel treatment alternatives, such as biologics that target particular molecules involved in the pathogenic process. Preliminary investigations and clinical trials have demonstrated the efficacy of biologics and provided additional insights for the era of refractory or corticosteroid-dependent EGE biologics.
