It occurs in 1.5 to 2% of ectopic pregnancies. It can be asymptomatic for several years. However, various complications can occur that lead to diagnosis. The authors report a case of lithopedion complicated by acute intestinal obstruction in a 24-year-old woman in her first pregnancy. This complication occurred after 12 months of amenorrhoea. A mass containing a calcified foetus was removed by laparotomy.展开更多

文摘OBJECTIVE:To reach consensus on the diagnostic criteria of syndrome of dampness obstruction in idiopathic membranous nephropathy(IMN)patients by literature research and expert investigation(interviews and a Delphi method).METHODS:Our study was consistent with T/CACM 1336-2020.We searched the monographs and references published in the past 40 years(1983-2022),and established the diagnostic criteria pool of waterdampness syndrome and dampness-turbidity syndrome in Traditional Chinese Medicine(TCM)based on literature by using frequency statistics and correlation analysis.Expert investigation(interview method and two rounds of Delphi method)was used to form the diagnostic criteria of water-dampness syndrome and dampnessturbidity syndrome of idiopathic membranous nephropathy.Clinical diagnostic test research was carried out,and compared with“Diagnostic Criteria for dampness syndrome”(T/CACM 1454-2023)to evaluate the authenticity,reliability and clinical application value of the standard.RESULTS:A total of 122 relevant guides,standards,monographs and documents were included through searching books and Chinese databases.Four experts were interviewed and two rounds of delphi method(75 experts nationwide)were carried out.The experts'opinions are relatively concentrated and the differences are small.Based on the weight of each index,the diagnostic criteria indexes of water-dampness syndrome and dampness-turbidity syndrome were selected.After discussion by the core group members,the diagnostic model of"necessary symptoms and optional symptoms"was established,and the final diagnostic criteria of waterdampness syndrome and dampness-turbidity syndrome were established.One hundred and ninety-one inpatients and outpatients of Guangdong Provincial Hospital of Chinese Medicine from January 2021 to February 2023 were included in Diagnostic test study.There was no statistical difference in gender,age and course of disease(P>0.05).The sensitivity and specificity of the trial standard were 90.34%and 73.33%respectively,while the sensitivity and specificity of T/CACM 1454-2023 were 99.43%and 6.67%,respectively.CONCLUSIONS:The consensus-based diagnostic criteria for IMN can be widely incorporated in TCM.A further clinical study will be conducted to analyze the diagnosis value and cut-off score of our IMN criteria.
文摘·AIM:To identify various risk factors that may play a significant role in the development of congenital nasolacrimal duct obstruction(CNLDO).·METHODS:This observational case-control study included a case group of 122 children less than two years of age with CNLDO who underwent probing and irrigation treatment at the ophthalmology department of Imam Khomeini Hospital in Ahvaz,Iran,from June 2022 to June2024.A control group of 122 age-matched children without CNLDO was also included for comparison.Data was collected from the children's medical records.·RESULTS:The study found a significant correlation between the occurrence of CNLDO and several maternal factors,such as preeclampsia,the use of levothyroxine,hypothyroidism,having more than three pregnancies(gravidity>3),natural pregnancy,and gestational diabetes mellitus.Additionally,in children,factors,such as oxygen therapy,anemia,reflux,jaundice,and a family history of CNLDO in first-degree relatives were associated with CNLDO,and maternal preeclampsia and hypothyroidism were found to significantly increase the risk of developing CNLDO in children.·CONCLUSION:Given that CNLDO affects both premature and full-term children,the present findings may potentially facilitate the early identification of children and infants at risk of nasolacrimal duct obstruction,thereby preventing the onset of chronic dacryocystitis.
文摘Endoscopic ultrasound-guided gastroenterostomy(EUS-GE)is emerging as a preferred approach for managing malignant gastric outlet obstruction.This technique offers a balance between the durability of surgical gastrojejunostomy(SGJ)and the minimally invasive nature of endoscopic methods.Compared to enteral stenting,EUS-GE shows superior outcomes,including higher long-term patency,lower symptom recurrence,and fewer reinterventions.It also demonstrates comparable or better efficacy than SGJ,with faster oral intake,shorter hospital stays,and reduced complications.However,EUS-GE requires specialized expertise,and long-term outcome data remain limited,so further research is needed to refine protocols and optimize patient selection.
文摘BACKGROUND Ileum adenocarcinoma(IA),a type of small bowel adenocarcinoma,is a rather uncommon factor associated with obstruction in small bowel.Owing to its location and indefinite clinical symptoms,the diagnosis of IA is difficult,and survival is usually poor.With respect to the rarity of this disease,very few studies have reported such cases to provide a reference for treatment.CASE SUMMARY In this manuscript,a case of a 48-year-old man presented with chronic right lower abdominal pain and distention,queasiness and emesis.A computed tomography scan revealed intestinal wall thickening and an intestinal obstruction in the terminal ileum.He was diagnosed with inflammatory bowel disease.However,his symptoms were not relieved after conservative treatment.The patient sub-sequently underwent exploratory laparotomy,and a tumour in the ileum measuring approximately 2.0 cm×2.0 cm that was located 20 cm from the ileocolic valve was discovered incidentally and was operatively resected along with the enlarged lymph nodes.Pathological examination revealed a stage IIA(T3N0M0)ulcerative IA.Along with imaging examinations,a diagnosis of primary IA with no lymph or distant metastases was considered.The patient was discharged and recovered well as of the writing of this manuscript.CONCLUSION IA should be considered as a differential diagnosis in cases of intestinal obstruction,and the recommended method for local disease treatment is surgery.
文摘BACKGROUND Recently,intestinal stenting combined with laparoscopic surgery has received increasing attention as a treatment option for acute intestinal obstruction.However,its safety and efficacy have not yet been established.AIM To assess the efficacy and safety of combining intestinal stenting with laparoscopic surgery for the management of acute intestinal obstruction.METHODS Clinical data from 74 patients with colorectal cancer and acute intestinal obstruction,who were admitted to the emergency department of the authors’hospital between October 2023 and November 2024,were collected and analyzed.Patients were divided into two groups based on the surgical intervention:A control group(emergency open surgery,n=37)and a study group(intestinal stent implantation combined with laparoscopic surgery,n=37).Observation indicators included stent placement rate,obstruction relief rate,and stent-related complications.RESULTS Intestinal stent placement was 100%successful in the study group,all of whom experienced relief from obstruction while exhibiting a significantly lower rate of ostomy creation and a higher rate of primary anastomosis than in the control group,as well as less intraoperative blood loss,shorter time to flatus,and shorter hospital stay.The complication rate was 5.41%(2/37;bleeding and re-obstruction),with no statistically significant difference between the two groups in terms of operative duration or perioperative mortality.The overall complication rates were 5.41%(2/37)and 21.62%(8/37)in the intervention and control groups,respectively.Tumor recurrence and overall survival rates were 2.70%and 97.30%in the study group and 13.51%and 91.89%in the control group,respectively.CONCLUSION Intestinal stenting relieved acute obstructions,reduced the number of emergency surgeries,and supported laparoscopic procedures while improving primary anastomosis rates,minimizing ostomy occurrence,surgical trauma,and complications,and accelerating recovery.
文摘The scope of management of malignant gastric outlet obstruction is ever-expanding.The therapeutic use of endoscopy is gaining popularity not just owing to its technical advancement and satisfactory patient outcomes.With technical success rates close to 96%,stent placement for palliating gastric obstruction has ensured a median survival of about 2 months post-deployment of gastro-duodenal stents.Understanding the correct concept of palliation is the need of the hour in management.Identifying the right patient for palliation,selecting the appropriate intervention and auditing the outcome are vital in delivering optimal care.Also,newer procedures such as endoscopic gastro-enterostomy offer promising outcomes in palliative care.

文摘Internal herniation(IH)refers to the movement of intra-abdominal organs or tissues out of their original position through normal or abnormal orifices and fissures in the peritoneum or mesentery and into an anatomic space within the abdominal cavity.Although the incidence of small bowel obstruction(SBO)caused by IH is very low(approximately 0.2%to 0.9%),its incidence may be increased in certain specific populations or in postoperative patients.Recently Kaw et al shared their 13-year experience of managing IHs in a tertiary care hospital in India.This retrospective study analyzed and determined the clinico-demographic profiles,radiological and operative findings and postoperative course of patients with IH and the association with SBO.The results provide valuable insights into early diagnosis and establishment of a timely treatment regimen for this condition and emphasize the importance of combining rapid imaging evaluation with the traditional therapeutic approach of laparoscopic surgery,thus providing a novel perspective on the diagnosis and treatment of SBO caused by IH.
文摘BACKGROUND Intestinal obstruction(IO)in pregnancy,though rare(1:1500-1:66000),carries high maternal(6%-10%)and fetal mortality(26%).Adhesions from prior surgery are the leading cause.Diagnosis is often delayed due to symptom overlap with nor-mal pregnancy,increasing risks of perforation and sepsis.CASE SUMMARY A 25-year-old gravida 2 para 1 woman at 28 weeks of gestation presented with 1-week constipation,feculent vomiting,and abdominal distension.She had a history of exploratory laparotomy in 2015 for blunt abdominal trauma.The diagnosis of IO in pregnancy was confirmed via abdominopelvic ultrasound and clinical findings.Interventions included conservative measures(nasogastric tube decompression,enemas)followed by emergency laparotomy with bowel resec-tion/anastomosis.Despite surgical management,the patient succumbed to septic shock.CONCLUSION High clinical suspicion,expedited cross-sectional imaging(computed tomogra-phy/Magnetic resonance imaging),and emergent surgery are critical to reduce mortality.
文摘BACKGROUND Groove pancreatitis(GP)is a rare focal chronic pancreatitis of the pancreaticoduodenal groove that is usually diagnosed in chronic alcoholics.However,it is often difficult to differentiate from pancreatic or periampullary cancers.In this study,we report a case of GP with the rare symptom of severe gastric outlet obstruction.CASE SUMMARY A 68-year-old man presented to our institution with severe gastric outlet obstruction accompanied by vomiting persisted for 3 days,severe electrolyte imbalance,and altered mental status with cardiac arrest.Differential diagnosis of cancers of the ampulla of Vater or duodenum was difficult due to discordant findings from preoperative imaging and an endoscopic biopsy of the lesion.In addition,the gastric outlet obstruction did not improve with conservative treatment;therefore,pancreatoduodenectomy was performed.Postoperatively,the histological findings revealed multiple cystic lesions in the duodenal wall that were collectively diagnosed as GP.The patient underwent a follow-up 3 years postoperatively and was found to have no postoperative sequelae.CONCLUSION In this case of GP,pancreatoduodenectomy safely treated severe gastric outlet obstruction when a cancer diagnosis could not be excluded.
文摘Duodenal stenting is a widely used palliative treatment for gastric outlet obstru-ction(GOO)caused by unresectable malignancies.Compared to surgical gastroje-junostomy,duodenal stenting allows for earlier oral intake,shorter hospita-lization,and earlier chemotherapy initiation.However,its long-term efficacy is limited by stent occlusion,which typically occurs 2-4 months post-procedure,due to tumor ingrowth,overgrowth,or food impaction.Covered stents can reduce tumor ingrowth but increase the migration risk,particularly in patients receiving chemotherapy.This review provides a comprehensive comparison of duodenal stenting,surgical gastrojejunostomy,and endoscopic ultrasound-guided gastroen-terostomy,by discussing their clinical outcomes,advantages,and limitations.We further explore stent selection based on stricture characteristics,optimal placement techniques,post-procedural management,and for handling complic-ations including occlusion,migration,bleeding,and perforation.Additionally,we address technical challenges and troubleshooting strategies,including mana-gement of guidewire-induced perforation,incomplete stent expansion,and bile duct obstruction for overlapping biliary and duodenal stricture cases.Despite its widespread clinical use,no prior review has comprehensively covered both the technical and clinical aspects of duodenal stenting so extensively.By providing a clinically oriented,practical guide,this review serves as a valuable resource for endoscopists and gastroenterologists,facilitating optimized decision-making and improved outcomes for patients with GOO in real-world practice.

文摘BACKGROUND Among all forms of heterotopic ossification,heterotopic mesenteric ossification(HMO)is rare,with fewer than 100 reported cases to date.Postoperative early small bowel obstruction caused by HMO is even rarer,presenting extremely high surgical risks,the potential for multiple surgeries,and a poor prognosis.There have been no reported cases of conservative treatment for resolving such early postoperative obstruction.CASE SUMMARY A 57-year-old male presented with severe postoperative small bowel obstruction shortly after undergoing open radical resection for transverse colon cancer.Laparotomy revealed extensive adhesions in the proximal jejunum and mesen-tery,making it too difficult to relieve without injuring the small bowel.Addi-tionally,multiple fixed nodules were found in the mesentery during the opera-tion.Pathology confirmed the presence of heterotopic ossification.The patient was treated with methylprednisolone on postoperative day 1,which gradually relieved his symptoms.CONCLUSION Hormone therapy may have a potential role in treating small bowel obstruction caused by early HMO after operative intervention.
文摘Lithopedion is a rare clinical situation characterised by the calcification of a foetus that has died during an ectopic pregnancy, usually in the abdominal cavity. It occurs in 1.5 to 2% of ectopic pregnancies. It can be asymptomatic for several years. However, various complications can occur that lead to diagnosis. The authors report a case of lithopedion complicated by acute intestinal obstruction in a 24-year-old woman in her first pregnancy. This complication occurred after 12 months of amenorrhoea. A mass containing a calcified foetus was removed by laparotomy.

文摘BACKGROUND Cancer-induced incomplete bowel obstruction presents numerous clinical cha-llenges,notably pain management and inflammation control.Conventional thera-pies provide limited relief,prompting investigation into complementary approa-ches.This study compares the efficacy of bottle gourd moxibustion combined with umbilical therapy(BGM-UT)plus standard palliative care vs standard Wes-tern palliative care alone in symptom alleviation and inflammation reduction.AIM To compare the efficacy of BGM-UT plus standard palliative care vs standard pa-lliative care alone in reducing inflammatory cytokine levels,alleviating symp-toms,and improving gastrointestinal recovery in cancer-induced incomplete bowel obstruction.METHODS A retrospective analysis was conducted on 109 patients aged 18-75 years with cancer-induced incomplete bowel obstruction treated at the Foshan Hospital of Traditional Chinese Medicine between October 2023 and September 2024.The participants were categorized into two groups:(1)Regular group receiving stan-dard palliative care;and(2)BGM-UT group receiving additional moxibustion therapy.The inclusion criteria included ongoing opioid use and a Karnofsky per-formance status score below 60.The treatments were evaluated for 3 weeks in terms of opioid consumption,gastrointestinal function recovery,brief pain inven-tory scores,traditional Chinese medicine symptom scores,and inflammatory cytokine levels.RESULTS Initially,the groups were demographically and clinically comparable.Post-treatment,the BGM-UT group showed significant reductions in opioid intake(P=0.027),improved gastrointestinal recovery times,and enhanced pain management as reflected by their lower brief pain inventory scores(P<0.05).Similarly,the improvement in traditional Chinese medicine scores was greater in the BGM-UT group than in the regular group(P<0.05).Inflam-matory markers including interleukin-6,tumor necrosis factor-α,and C-reactive protein decreased significantly in the BGM-UT group,indicating the superior anti-inflammatory effects of this treatment(P<0.05).CONCLUSION The addition of BGM-UT to standard palliative care enhances pain relief,accelerates gastrointestinal recovery,and effectively reduces inflammatory cytokine levels in patients with cancer-induced incomplete bowel obstruction.This combination therapy offers a promising complementary approach to managing this challenging condition.Further prospective studies are warranted to validate these findings and explore underlying mechanisms.
文摘AIM:To reveal the research hotspots,trends,and future prospects of lacrimal duct obstruction disease(LDOD)from 1900 to 2024 through the bibliometric and visualized analysis,providing a directional guidance for research in this field.METHODS:The Web of Science Core Collection database was used to retrieve relevant literature.Data analysis and visualization were conducted using VOSviewer 1.6.20 and CiteSpace 6.3.1,including annual publication volume,trends,research areas,country/region and institution distribution,journal and co-cited journal analysis,author and co-cited author analysis,keyword and burst keyword analysis,etc.RESULTS:The study included a total of 1481 articles,revealing an overall upward trend in research on LDOD,with ophthalmology being the predominant field.While the United States previously led research efforts,India and China have emerged as key contributors since 2015.Mohammad Javed Ali stands out as the most influential author in this research area.Ophthalmic Plastic and Reconstructive Surgery has published the highest number of related articles,whereas Ophthalmology has the highest co-citation.The current focal points of research include minimally invasive and precise modifications to dacryocystorhinostomy,along with intubation,new materials for stents,and disease pathogenesis.CONCLUSION:LDOD research has garnered widely attention and exhibits a steady upward trend.Since 1900,the United States,China,and India have been the leading contributors to this field.Ophthalmologists continue to be the primary driving force behind LDOD research.The findings of this study suggest that at the forefront of LDOD research,our focus has long been on refining and innovating surgical treatment.The minimally invasive and precise modification of lacrimal surgery,represented by dacryocystorhinostomy,is the ongoing developmental direction of this field.Rapid interdisciplinary integration and in-depth exploration of pathogenesis and allergic inflammation will lead to the emergence of new materials,innovative technologies,and safer clinical treatment protocols.
文摘BACKGROUND Hepatic venous outflow obstruction(HVOO)is a rare but serious complication of liver transplantation,particularly in piggyback liver transplantation techniques where the inferior vena cava(IVC)is preserved.CASE SUMMARY A transplanted liver patient underwent retransplantation due to hepatic artery thrombosis and subsequently developed HVOO caused by graft compression of the IVC.A novel approach using a retrohepatic tissue expander effectively relieved the IVC compression,restored venous outflow,and stabilized hemodynamics.We discuss this case in the context of current treatment options and advances in HVOO management,from endovascular interventions such as balloon dilation and stenting to innovative surgical solutions such as graft repositioning and retrohepatic implants.CONCLUSION This case shows how important personalized treatments are for managing HVOO and how tissue expanders can be an adjustable and less invasive option.
