BACKGROUND

Enteric duplication cyst is a rare congenital anomaly of the digestive tract, affecting 0.2% of children and 5- 6% of adults, occurring in 1 in 4,500 births. Intussusception is uncommon in adults, accounting for less than 5% of cases, and is found in 1% of bowel obstruction patients. Clinical symptoms in adults can differ from the typical pediatric presentation.

CASE

A 40-year-old female was hospitalized with epigastric pain and vomiting, which began 12 hours prior to admission. She experienced crampy pain, escalating to severe pain radiating to the right upper quadrant, along with 12 episodes of non-bilious vomiting. She had a previous history of acute cholecystitis and no known comorbidities. Upon admission, her blood pressure was elevated, and she had icteric sclerae and a tender right upper quadrant with a mass in the epigastrium. Laboratory findings showed leukocytosis, hypokalemia, hypoalbuminemia, and hyperbilirubinemia. A computed tomography of the whole abdomen with contrast revealed duodenojejunal intussusception with biliary obstruction, along with a duodenal duplication cyst measuring 4.2 x 5.8 cm, acting as the lead point, with invagination of part of the pancreatic head into the intussusception. She was managed with decompression, medications, and intravenous antibiotics. After three days, she underwent exploratory laparotomy, pancreatoduodenectomy, segmental resection of the jejunum, and anastomosis procedures. Histopathology confirmed the duodenal duplication cyst, showing intestinal-type mucosa lining exhibiting ischemic necrosis with no atypia or malignant tumor cells. The patient tolerated the procedure well, and her symptoms resolved. She was discharged on the 14th hospital day in stable condition.

CONCLUSION

Adult duodenojejunal intussusception is a rare disease that is difficult to diagnose due to its nonspecific symptoms and is possible in cases of duplication cysts which can act as a lead point, such as in our patient. Therefore, a high index of suspicion and imaging plays an important role in the diagnosis of a duplication cyst with intussusception in adults especially those presenting with abdominal pain, vomiting, and jaundice. A correct and timely diagnosis is needed to prevent various complications including bowel infarction and sepsis.

OBJECTIVES: This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment. METHODS: Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed. Then, the data were imported into MIMICS software to observe 3D changes in the position and structure of the mandibular nerve canal, followed by a comparative analysis. RESULTS: The total displacement of the mandibular canal was (1.89±0.21) mm on the decompression side and (0.80±0.19) mm on the curettage side. Vertically, the displacement range of the mandibular canal on the decompression side (M=1.03, SD=0.17) was larger than on the curettage side (M=0.52, SD=0.010) within nine months post-operation. In the buccal-lingual direction, the ratio of the thickness of the buccal plate to the lingual plate gradually increased with time. The amount of bone reconstruction at the part of the mandibular nerve canal closest to the cyst was (1.75±0.15) mm on the decompression side and (1.45±0.09) mm on the curettage side after nine months. CONCLUSIONS The mandibular nerve canal showed varying degrees of recovery and "relocation" after two surgical procedures. Osteogenesis around the mandibular nerve canal was more remarkable after decompression than after curettage. Therefore, for large odontogenic keratocyst, decompression is recommended as the initial treatment, followed by secondary curettage nine months later.

Pathological fractures after jaw cyst surgery are rare clinically but are a serious complication. Once a pathological fracture occurs, treatment time and economic costs increase, and doctors face difficulty in handling it. This article reports a case of a patient with mandibular pathological fractures after multiple odontogenic keratocyst surgery of the jaw. Mandibular lesions were located in the bilateral mandibular angles and had macrocystic changes. We adopted a conservative treatment plan, and the treatment effect was good. We also discussed and analyzed relevant literature to provide a reference for clinicians.

Basal Cell Nevus Syndrome (BCNS) is a rare autosomal dominant disorder characterized by a range of abnormalities, most notably multiple basal cell carcinomas (BCCs), odontogenic keratocysts, and palmar and/or plantar pits. BCC is the most common form of skin cancer globally. It is typically locally invasive and very rarely metastasizes, with distal metastases occurring in only 0.00028% to 0.55% of cases.

We present a case of a 68-year-old Filipino woman who was diagnosed with BCNS. She presented with multiple black nodules and plaques on her face and neck, histopathologically confirmed as BCCs. In addition, the presence of palmoplantar pits and calcification of the falx cerebri met three of the six major criteria for BCNS. Computed tomography (CT) and bone scans, revealed multiple bone metastases in the cranium, spine, sternum, and ribs. No previous cases of metastasis in a BCNS patient have been reported in the Philippines, making this the first documented case.

BACKGROUND AND OBJECTIVE

Choledochal cysts (CC) are rare congenital, cystic dilations of the biliary tree occurring predominantly in Asian populations and in females. Patients are usually children presenting with any of the following: abdominal pain, palpable abdominal mass, and jaundice. Its congenital nature hints at a potential genetic cause. A possible causal gene is TP53, a tumor suppressor with a germline variant called rs201753350 (c.91G>A) that changed from a G allele to an A allele, decreasing the cell proliferation suppressing activity of its functional protein. Currently, there is no information on the TP53 rs201753350 germline variant available for the Filipino population. This study determined the prevalence of rs201753350 and the association between the functional G allele, the rs201753350 germline variant A allele, and the occurrence of CCs in Filipino pediatric patients in a tertiary government hospital.

METHODS

Genomic DNA was extracted from blood samples of pediatric patients clinically diagnosed with CC. Controls were DNA samples collected from a previous study. The samples underwent PCR, electrophoresis, and sequencing.

RESULTS

A total of 109 participants (22 cases and 87 controls) were included in the study. The A allele (22.94%) occurs at a lower frequency than the G allele (77.06%) among both cases and controls. More individuals have a homozygous G/G genotype (54.13%) than a heterozygous A/G genotype (45.87%) while the homozygous A/A genotype was not observed. The estimated risk of choledochal cyst occurrence is significantly lower in individuals with the A allele (PR: 0.08, 95% CI: 0.01 – 0.55) and the A/G genotype (PR: 0.06, 95% CI: 0.01 – 0.40).

CONCLUSION

There is no significant evidence to suggest an association between the TP53 rs201753350 germline variant and the occurrence of choledochal cysts in Filipinos. It is recommended that other mutations within and beyond the TP53 gene be investigated for possible associations with choledochal cyst occurrence.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

OBJECTIVES: In recent years, the incidence and detection rate of pancreatic cystic lesions (PCLs) have increased significantly. Endoscopic ultrasound (EUS) plays an indispensable role in the diagnosis and differential diagnosis of PCLs. However, evidence comparing the diagnostic performance of EUS-guided fine-needle aspiration (EUS-FNA) and fine-needle biopsy (FNB) remains limited. This study aims to compare the diagnostic yield, adequacy of tissue acquisition, and safety between EUS-FNA and EUS-FNB in evaluating PCLs to inform clinical practice. METHODS: A retrospective review was conducted on patients with PCLs who underwent either EUS-FNA or EUS-FNB between January 2014 and August 2021. The diagnostic yield, tissue acquisition adequacy, and incidence of adverse events were compared between the 2 groups. RESULTS: A total of 90 patients with PCLs were included (52 in the FNA group and 38 in the FNB group). The diagnostic yield was similar between the FNA and FNB groups (94.2% vs 94.7%, P>0.05). The adequacy of tissue acquisition was 71.2% in the FNA group and 81.6% in the FNB group (P>0.05). No statistically significant difference was observed in the incidence of adverse events between the 2 groups (P>0.05). CONCLUSIONS Both EUS-FNA and EUS-FNB demonstrate equally high diagnostic yields and tissue adequacy in PCLs, with excellent safety profiles. Both methods are safe and effective diagnostic tools for evaluating PCLs.

Objective:To explore the therapeutic strategy for laryngeal cysts in infants. Methods:A retrospective analysis of the clinical data of 19 children with laryngeal cysts treated in Kunming Children's Hospital from January 2020 to January 2023. All patients were diagnosed through electronic laryngoscopy examination. Twelve neonates were admitted to the neonatal intensive care unit. Five of them received mechanical ventilation with tracheal intubation before surgery due to severe respiratory distress, and seven received oxygen therapy with a head mask. The remaining seven children were admitted to Department of Otolaryngology Head and Neck Surgery, of which three cases were treated with oxygen therapy through a mask during sleep due to frequent shortness of breath during sleep. All patients underwent low-temperature plasma radiofrequency ablation under general anesthesia to remove the cysts. Results:Three newborns were unable to have their tracheal tubes removed due to complications with pneumonia after surgery, while the rest of the children were able to have their tubes successfully removed after complete anesthesia, and no gastric tubes were placed. All postoperative respiratory difficulties in the children disappeared, and there were no complications such as bleeding, hoarseness, or laryngeal stenosis. Five pediatric patients had incomplete relief of laryngeal ringing symptoms one month after surgery, and electronic laryngoscopy diagnosed laryngeal softening. Regular follow-up is recommended. One child relapsed 4 months after surgery and underwent a follow-up surgery six months later without recurrence. Conclusion:Endoscopic low-temperature plasma radiofrequency ablation is an effective surgical method for treating laryngeal cysts, with a low postoperative recurrence rate. Laryngeal cysts may be accompanied by laryngeal softening, which may be a possible reason for the postoperative symptoms not improving.

Objective:To explore the clinical manifestations, recurrence factors, and outcomes of revision surgery for recurrent thyroglossal duct cysts and fistulas in children. Methods:A retrospective study was conducted on the clinical manifestations, the relationship between cysts/ fistulas and residual hyoid bone of 10 patients with recurrent thyroglossal cysts and fistulas admitted to our hospital from July 2015 to July 2023, as well as the methods and effects of revision surgery. Results:The recurrence time after the initial surgery was between 7 months and 6 years, with an average of 2 years and 1 month.Clinical manifestations: 50%（5 cases） of patients have recurrent cysts near the incision, 40%（4 cases） had recurrent infections at the incision and eventually form fistulas, and 10%（1 case） experienced sleep snoring and pharyngeal trouble, were diagnosed with lingual thyroglossal duct cyst through laryngoscopy. All cysts or fistulas are connected to residual hyoid bodies, and three cases have intact hyoid bodies.Revision surgery: Nine cases underwent modified Sistrunk surgery, removing cysts, fistulas, and residual hyoid bodies. Suspension laryngoscopy and coblation were employed to treat the lingual thyroglossal duct cyst. After the revision surgery, follow-up was conducted for 8 months to 3 years, and no recurrence was found. Conclusion:All recurrences of thyroglossal duct cysts in this study were associated with residual hyoid bodies. Therefore, for thyroglossal duct cysts or fistulas, whether it is the first surgery or a revision surgery, it is recommended to choose the optimized Sistrunk operation, with the key point being complete resection of the hyoid body. Cases with lingual thyroglossal duct cyst can be treated with suspension laryngoscopy by coblation. Whether to remove the residual hyoid body requires further observation.

Objective:To summarized the clinical characteristics and surgical management of anterior cervical enterogenic in pediatric patients. Methods:Clinical data were retrospectively analyzed for 9 children with pathologically confirmed anterior cervical enterogenic cysts（including bronchogenic and esophagogenic subtypes） treated at the Children's Hospital of Shandong University（Jinan Children's Hospital） between January 1, 2020, and November 30, 2023. Results:Nine patients（6 males and 3 females） were involved in this study, aged 14 days to 10 years old. There were 4 cases on the left side, 4 on the right side, and 1 in the middle of the neck. All patients presented with neck masses. The patients were followed up from 3 months to 35 months after surgery and recovered well, with no recurrence or complications observed. Conclusion:①Anterior intestinal cysts in children are rare and easy to be misdiagnosed. ②Concurrent branchial cleft fistulas or associated anomalies may coexist, necessitating comprehensive evaluation. ③Preoperative diagnosis is not easy and mainly depends on pathological diagnosis. ④The treatment of anterior cervical enterogenic cysts in children is surgical resection of the lesion.
