Malignant triton tumor in the abdominal wall:A case report

BACKGROUND Malignant triton tumors(MTTs)comprise a subgroup of malignant peripheral nerve sheath tumors(MPNSTs)that exhibits rhabdomyosarcomatous differen-tiation and follow an aggressive course.MTTs are primarily located along peripheral nerves.Cases of MTTs in the abdominal wall have not been reported.MTT has a poorer prognosis than classic MPNSTs,and accurate diagnosis necessitates a keen understanding of the clinical history and knowledge of its differential diagnosis intricacies.Treatment for MTTs mirrors that for MPNSTs and is predominantly surgical.CASE SUMMARY A 49-year-old woman presented with a subcutaneous mass in her lower abdo-minal wall and a pre-existing surgical scar that had grown slowly over 3-4 months before the consultation.She had previously undergone radical hysterectomy and concurrent chemo-radiotherapy for cervical cancer approximately 5 years prior to the consultation.Abdominal computed tomography(CT)showed a 1.3 cm midline mass in the lower abdomen with infiltration into the rectus abdominis muscle.There was no sign of metastasis(T1N0M0).An incisional biopsy identified sporadic MTT of the lower abdomen.A comprehensive surgical excision with a 3 cm margin inclusive of the peritoneum was executed.Subse-quently,the general surgeon utilized an approach akin to the open peritoneal onlay mesh technique.The patient underwent additional treatment with an excision shaped as a mini-abdominoplasty for the skin defect.No complications arose,and annual follow-up CTs did not show signs of recurrence or metastasis.CONCLUSION An abdominal MTT was efficaciously treated with extensive excision and abdominal wall reconstruction,eliminating the need for postoperative radiotherapy.

Perioperative management of postoperative sigmoid colon cancer complicated by a large abdominal wall defect:A case report

BACKGROUND Large abdominal wall defect(LAWD)measures>20 cm in width.LAWD can easily lead to intestinal necrosis,peritonitis,other complications,and even mul-tiple organ dysfunction syndrome.Multiple intestinal fistulas are high-flow fis-tulas that can cause severe water–electrolyte imbalance and malnutrition,as well as inflammation,high metabolic status,and chronic intestinal failure caused by intestinal fluid corrosion in tissues around the orifice fistulas.CASE SUMMARY This article summarizes the nursing experience of a patient with sigmoid carci-noma who has LAWD with multiple intestinal fistula due to repeated operations for postoperative complications.The key points of care:Scientific assessment of nutritional status,dynamic adjustment of nutritional support programmes,com-prehensive adoption of enteral nutrition,parenteral nutrition and combined nut-rition of enteral and parenteral;taking good care of abdominal wall defects and intestinal fistulas;continuous flushing of the abdominal drainage tube and low negative pressure drainage;prevention of venous thrombosis;strengthening of physical exercise;implementation of positive psychological interventions.CONCLUSION After more than 7 months of careful care,the patient's physical fitness has been well recovered,local inflammation is well controlled,which wins the opportunity for the operation,and the postoperative recovery is good.

Primary yolk sac tumor in the abdominal wall in a 20-year-old woman:A case report

BACKGROUND Extragonadal yolk sac tumors(YSTs)are rare,with only a low reported tumor occurrence outside the gonads locally and abroad.Extragonadal YSTs are usually a diagnostic challenge,because they are infrequent,but also because a thoughtful and detailed differential diagnostic process must be performed.CASE SUMMARY Here we present a case of an abdominal wall YST in a 20-year-old woman admitted with a tumor in the lower abdomen close to the umbilicus.The tumorectomy was performed.The histological examination revealed characteristic findings such as Schiller-Duval bodies,loose reticular structures,papillary structures,and eosinophilic globules.According to the immunohistochemical staining,the tumor tissue was positive for broad-spectrum cytokeratin,Spalt-like transcription factor 4,glypican-3,CD117,and epithelial membrane antigen.Based on the clinical information,histological features,and immunohistochemical staining profile,the tumor was diagnosed as a YST present in the abdominal wall.CONCLUSION Based on the clinical information,histological features,and immunohistochemical staining profile described above,the tumor was diagnosed as a primary YST in the abdominal wall.

Complications of high intensity focused ultrasound in patients with recurrent and metastatic abdominal tumors

AIM： To analyze the local and systemic complications of high intensity focused ultrasound （HIFU） for patients with recurrent and metastatic abdominal tumors. METHODS： From Aug 2001 to Aug 2004, 17 patients with recurrent and metastatic abdominal tumors were enrolled in this study. Real-time sonography was taken, and vital signs, liver and kidney function, skin burns, local reactions, and systemic effects were observed and recored before, during, and after HIFU. CT and MR/were also taken before and after HIFU. RESULTS： All 17 patients had skin burns and pain in the treatment region; the next common complication was neurapraxia of the stomach and intestines to variable degrees. The other local and systemic complications were relatively rare. Severe complications were present in two patients; one developed a superior mesenteric artery infarction resulting in necrosis of the entire small intestines, and the other one suffered from a perforation in terminal ileum due to HIFU treatment. CONCLUSION： Although HIFU is a one of noninvasive treatments for the recurrent and metastatic abdominal tumors, there are still some common and severe complications which need serious consideration.

Intra-abdominal inflammatory myofibroblastic tumor:Spontaneous regression

Inflammatory myofibroblastic tumors are usually treated by surgical resection. We herein report two cases of intra-abdominal inflammatory myofibroblastic tumors that were unresectable and underwent spontaneous regression without any treatment. Our case report and literature review show that regression is more common in the middle-aged and older male populations. Abdominal discomfort and fever were the most common symptoms, but the majority of patients had no obvious physical signs. There was no specific indicator for diagnosis. The majority of the lesions regressed within3 mo and nearly all of the masses completely resolved within 1 year. We conclude that the clinical characteristics of inflammatory myofibroblastic tumors are variable and, accordingly, the disease needs to be subdivided and treated on an individual basis. Surgery is always the first-line treatment; however, for those masses assessed as unresectable, conservative therapy with in-tense follow-up should be considered.

Primary Extra-Gastrointestinal Stromal Tumor (GIST) arising from mesentery of small bowel and presenting as abdominal mass: A rare entity

Introduction: Majority of mesenchymal tumors of gastrointestinal tract are Gastrointestinal Stromal Tumor (GIST). It is, however, a rare tumor, accounting for less than 1% of primary gastrointestinal (GI) neoplasms. Though, these tumors are refractory to conventional chemotherapy or radiotherapy but show a good response to targeted adjuvant chemotherapy with tyrosine kinase inhibitors following surgical resection. Case Report: we report here a case of primary Extra-GIST tumor arising from mesentry of small bowel near duodeno-jejunal junction in a 69 years old male patient. The patient presented with a palpable mass in upper abdomen for past 15 days. On examination, a non-tender mobile lump of size around 17 × 10 cm, with bosselated surface and firm in consistency was palpable involving epigastric, left hypochondrium and umbilical region. Contrast enhanced computed tomography of abdomen revealed a heterogenous mesentric mass. On surgical intervention a mass was found involving mesentery near dudenojejunal junction without involvement of gastrointestinal tract. Complete surgical resection of the tumor was done and adjuvant chemotherapy with Imatinib mesylate was started as HPE revealing GIST with mitotic index of >10/50 HPF and 17 × 10 cm size placed the patient in high risk category. Patient was discharged on 12th of post-operative day with advice of regular follow-up. Conclusion: GIST occurrence is not restricted to bowel but can involve unusual sites also. The mainstay of treatment remains surgical resection with adequate margin. In cases where tumour has malignant potential (high mitotic figures on histopathology) adjuvent treatment with tyrosine kinase may prevent or delay relapse.

Clinical Report on Pharmacological Prevention of Deep Vein Thrombosis after Radical Resection of Abdominal Tumors

Aim: The aim of this paper is to summarize the experience and results of deep vein thrombosis prevention after standardized abdominal tumor resection and lymph node dissection, and to investigate standardized treatment methods for postoperative thrombosis prevention. Methods: We performed a retrospective analysis of the clinical data for 548 patients who were given low molecular weight heparin, low molecular weight dextran, or IV salvia to prevent thrombosis development between January 2007 and April 2010 after standardized abdominal tumor resection and lymph node dissection. Patients were divided into the following three groups based on the treatment period and treatment schedule: group 1 included 163 patients who had been treated between January 2007 and March 2008 and received a 7-day course of daily low molecular weight dextran (500 mL) and salvia injection (0.2 g) postoperatively;group 2 included 149 patients who had been treated between April 2008 and March 2009 and received a 7-day course of daily low molecular weight dextran (500 mL), salvia injection (0.2 g), and low molecular weight heparin (40 mg) postoperatively;group 3 included 236 patients who had been treated between April 2009 and April 2010 and postoperatively received a 7-day course of daily low molecular weight dextran (500 mL) and salvia injection (0.2 g), and on postoperative day 3 were started on an additional 7-day course of daily low molecular weight heparin (40 mg). Then, we performed comparative analysis of the treatment efficacy and concomitant symptoms. Results: In group 1, 64 of the 163 cases (39.3%) were positive for D-dimer, and 15 (9.2%) cases were positive for DVT based on Doppler imaging of the lower extremities. In group 2, 38 cases (25.5%) were positive for D-dimer and 3 cases (2.0%) for DVT. In group 3, 62 cases (26.3%) were positive for D-dimer and 6 cases (2.5%) for DVT. In general, the administration of low molecular weight heparin for anticoagulation in groups 2 and 3 led to significant reduction of thromboses when compared to group 1. However, altering the initiation day of low molecular weight heparin administration between groups 2 and 3 did not result in significant differences in the rate of thrombosis formation. Through clinical observation, early administration of low molecular weight heparin may increase adverse effects. Conclusion: We have demonstrated the superior efficacy of postoperative administration of low molecular weight dextran and IV salvia with additional subcutaneous injection of low molecular weight heparin on postoperative day 3 to prevent DVT development after radical resection of abdominal tumors.

Extragastrointestinal stromal tumors with diffuse membranous distribution with bleeding:A case report

BACKGROUND Extragastrointestinal stromal tumors(EGIST)and gastrointestinal stromal tumors are of similar pathological type and form.Here we report a rare case of EGIST diffusely distributed in membranous tissue in abdominal cavity,the feature of which included diffuse tumors at membranous tissue in entire abdominal cavity and spontaneous bleeding of the tumors.CASE SUMMARY The patient was a 71-year man and hospitalized due to continuous pain at lower abdomen for more than 10 days.Upon physical examination,the patient had flat and tough abdomen with mild pressing pain at lower abdomen,no obvious abdominal mass was touchable,and shifting dullness was positive.Positron emission tomography-computed tomography(CT)showed that in his peritoneal cavity,there were multiple nodules of various sizes,seroperitoneum,multiple enlarged lymph nodes in abdominal/pelvic cavity and right external ilium as well as pulmonary nodules.Plain CT scanning at epigastrium/hypogastrium/pelvic cavity+enhanced three-dimensional reconstruction revealed multiple soft tissue nodules in abdominal/pelvic cavity,peritoneum and right groin.Tumor marker of carbohydrate antigen 125 was 808 U/mL,diffuse tuberous tumor was seen in abdominal/pelvic cavity during operation with hematocelia,and postoperative pathological examination confirmed EGIST.Imatinib was administered with better therapeutic effect.CONCLUSION Gene testing showed breast cancer susceptibility gene 1 interacting protein C-terminal helicase 1 and KIT genovariation,and the patient was treated with imatinib follow-up visit found that his clinical symptoms disappeared and the tumor load alleviated obviously via imageological examination.

Postoperative encapsulated hemoperitoneum in a patient with gastric stromal tumor treated by exposed endoscopic full-thickness resection: A case report

BACKGROUND Gastric stromal tumors,originating from mesenchymal tissues,are one of the most common tumors of the digestive tract.For stromal tumors originating from the muscularis propria,compared with conventional endoscopic submucosal dissection(ESD),endoscopic full-thickness resection(EFTR)can remove deep lesions and digestive tract wall tumors completely.However,this technique has major limitations such as perforation,postoperative bleeding,and post-polypectomy syndrome.Herein,we report a case of postoperative serous surface bleeding which formed an encapsulated hemoperitoneum in a patient with gastric stromal tumor that was treated with exposed EFTR.Feasible treatment options to address this complication are described.CASE SUMMARY A 47-year-old male patient had a hemispherical protrusion found during gastric endoscopic ultrasonography,located at the upper gastric curvature adjacent to the stomach fundus,with a smooth surface mucosa and poor mobility.The lesion was 19.3 mm×16.1 mm in size and originated from the fourth ultrasound layer.Computed tomography(CT)revealed no significant evidence of lymph node enlargement or distant metastasis.Using conventional ESD technology for mucosal pre-resection,exposed EFTR was performed to resect the intact tumor in order to achieve a definitive histopathological diagnosis.Based on its morphology and immunohistochemical expression of CD117 and DOG-1,the lesion was proven to be consistent with a gastric stromal tumor.Six days after exposed EFTR,CT showed a large amount of encapsulated fluid and gas accumulation around the stomach.In addition,gastroscopy suggested intracavitary bleeding and abdominal puncture drainage indicated serosal bleeding.Based on these findings,the patient was diagnosed with serosal bleeding resulting in encapsulated abdominal hemorrhage after exposed EFTR for a gastric stromal tumor.The patient received combined treatments,such as hemostasis under gastroscopy,gastrointestinal decompression,and abdominal drainage.All examinations were normal within six months of follow-up.CONCLUSION This patient developed serous surface bleeding in the gastric cavity following exposed EFTR.Serosal bleeding resulting in an encapsulated hemoperitoneum is rare in clinical practice.The combined treatment may replace certain surgical techniques.

Clinical analysis of abdominal aorta block in operation of gynecologic tumor

Objective:To evaluate the clinical effects of the abdominal aorta block in controlling haemorrhage during operations of the gynecologic tumor. Methods: From July 1965 to January 2005. we collected patients (n = 49) of gynecologic tumor complicated with haemorrhage during operations, who were divided into 3 groups: preventive blocking group (PG, n=12), treatment blocking group (TG, n = 20) used abdominal aorta block technique with sterilized cotton band and silica gel tube, and control group (CG, n = 17) which were used the regular haemostatic methods, such as ligature, suture and ribbon gauze packing. During operations, the vital signs including the amount of bleeding and transfusion were measured. Results: Compared with the CG, the amount of bleeding and transfusion in the PG and TG decreased significantly (P<0. 01). After using the technique, 32 cases of haemorrhage were controlled completely. All patients finished operation smoothly in the end and the vital signs were stable. The vision field of operation was clear and the operating time was shortened dramatically (3. 0 h vs 5. 7 h and 3. 8 h vs 5. 7 h, P< 0. 01). No complications caused by the block occurred in the post-operation. Conclusion: Lower abdominal aorta block is safe and effective in controlling haemorrhage during operations of the gynecologic tumor.

Ampullary Neuroendocrine Tumor: A Rare Cause of Recurrent Abdominal Pain

Ampullary Neuroendocrine tumor (ANET) is a rare GI malignancy, representing less than 1% of GI neuroendocrine tumors and less than 2% of ampullary tumors. Traditional treatment is often a pancreaticoduodenectomy;however, local and endoscopic resections have been successful. We report a rare case of ANET in a 21-year-old Burmese man who presented with a 6-year history of non-specific intermittent abdominal pain who was successfully managed through transduodenal ampullectomy. At 24 months postoperatively he remains disease and symptom free. ANET is a rare cause of recurrent abdominal pain, and local excision of small ANETs can be an alternative, less morbid treatment for young patients. We follow the case with a brief review of the literature.

Complete Remission by Primary Chemotherapy of Advanced Non-Seminomatous Germ Cell Tumor in an Intra-Abdominal Testis

Ectopic testis predisposes to a high risk of germ cell tumor development. Treatment of advanced testicular germ cell tumor developing in an uncorrected abdominal testis is based on primary chemotherapy followed by removal of the testis along with residual masses. However, persistence of viable tumor particularly in the testis is always noted since testis penetration of chemotherapeutic agents is reduced. We report a case of complete pathological remission of a patient with advanced non-seminomatous germ cell tumor in intra-abdominal testis by primary chemotherapy alone, with a review of the literature.

Treatment of large defect of abdominal wall after tumors resection by transposition of tissue flaps with pedicle

Objective To report evaluat of division region of abdominal wall large defect after tumors resection and repair methods by tissue flaps with pedicle. Methods Form October 1992 to September 2001, 8 cases large abdominal wall defect after malignant tumors resection(10 × 10 cm-32 cm×32 cm) were reviewed. The defectcontributed:Ⅰ region, 2 cases; twin-Ⅱ region, 2; Ⅲ region, 2; Ⅰ and Ⅱ region of one side, 1 and total abdominal wall,one case, The tissue flaps of transposition included: gracilis myocutaneous flaps, 4; retus abdominal myocutaneous flaps, 2; external abdominal obligue musculo-fascia flaps, 2; latissimus dorsi muscle, tensor fasciae latae muscle and retus femoris muscle flaps each, 1. One patient used MycroMesh also. Results In the course of peroperation, the incisions of 8 cases healed in first time; total tissue flaps survived and all pateints started exercise left the bed in 3 weeks. All 8 patients were followed up average of 2 years and 5 months: the success rate of reconstruction

22-gauge core vs 22-gauge aspiration needle for endoscopic ultrasound-guided sampling of abdominal masses

AIM To compare the aspiration needle(AN) and core biopsy needle(PC) in endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) of abdominal masses.METHODS Consecutive patients referred for EUS-FNA were included in this prospective single-center trial. Each patient underwent a puncture of the lesion with both standard 22-gauge(G) AN(Echo Tip Ultra; Cook Medical, Bloomington, Indiana, United States) and the novel 22 G PC(Echo Tip Pro Core; Cook Medical, Bloomington, Indiana, United States) in a randomized fashion; histology was attempted in the PC group only. The main study endpoint was the overall diagnostic accuracy, including the contribution of histology to the final diagnosis. Secondary outcome measures included material adequacy, number of needle passes, and complications.RESULTS Fifty six consecutive patients(29 men; mean age 68 years) with pancreatic lesions(n = 38), lymphadenopathy(n = 13), submucosal tumors(n = 4), or others lesions(n = 1) underwent EUS-FNA using both of the needles in a randomized order. AN and PC reached similar overall results for diagnostic accuracy(AN: 88.9 vs PC: 96.1, P = 0.25), specimen adequacy(AN: 96.4% vs PC: 91.1%, P = 0.38), mean number of passes(AN: 1.5 vs PC: 1.7, P = 0.14), mean cellularity score(AN: 1.7 vs PC: 1.1, P = 0.058), and complications(none). A diagnosis on the basis of histology was achieved in the PC group in 36(64.3%) patients, and in 2 of those as the sole modality. In patients with available histology the mean cellularity score was higher for AN(AN: 1.7 vs PC: 1.0, P = 0.034); no other differences were of statistical significance.CONCLUSION Both needles achieved high overall diagnostic yields and similar performance characteristics for cytological diagnosis; histological analysis was only possible in 2/3 of cases with the new needle.

Lung Stereotactic Body Radiotherapy Using an Abdominal Compression System, “Air-Bag System”

We investigated respiratory tumor motion in lung stereotactic body radiotherapy (SBRT) with use of the “Air-Bag System”. 114 patients underwent four-dimensional (4D) computed tomography (CT) from October 2010 to April 2012. Gross tumor volume (GTV) was 8.1 ± 11.0 cc (range 0.3 - 77.5 cc). The tumor site was the upper and middle lobes in 62 cases, and lower lobe in 52 cases. The Air-Bag SystemTM consists of an inelastic air bag connected to a second smaller elastic air bag. The inelastic air bag is placed between the patient’s body surface and a HipFix and is secured by pressure adjustment via the elastic air bag. To assess respiratory tumor motion, the centroid of the tumor position is measured in the left-right, anterior-posterior, and caudal-cranial directions using the iPlan RT DoseTM treatment planning system. Respiratory tumor motion vector for patients with upper/middle and lower lobe tumors was 3.0 ± 2.2 mm (range, 0.4 - 11.7 mm) and 6.5 ± 4.6 mm (range, 0.4 - 22.0 mm) respectively, with this difference being significant (p < 0.05). Mean respiratory tumor motion for all patients was 0.9 ± 0.6 mm (range, 0.1 - 3.6 mm) in the left-right direction, 1.5 ± 1.1 mm (range, 0.1 - 5.7 mm) in the anterior-posterior direction, 4.1 ± 4.0 mm (range, 0.1 - 21.4 mm) in the caudal-cranial direction, and 4.7 ± 4.0 mm (range, 0.4 - 22.0 mm) overall. The Air-Bag System is expected to be provided an effective reduction in the motion of lung tumors.

Refractory Ascites Revealing an Ovarian Yolk Sac Tumor with Intraperitoneal Rupture

Yolk sac tumors of the ovary are rare entities that account for 2% - 5% of all ovarian tumors. They represent the second most common histological variant of malignant germ cell tumors of the ovary after dysgerminomas. Yolk sac tumors are most commonly encountered in women in the second and third decades. Microscopically, they are highly polymorphic and can present in a pure form or associated with another contingent of germ cell tumor. We report the case of a 26-year-old woman, who underwent surgery for a large right ovarian tumor rupturing into the peritoneal cavity. The ovarian tumor was revealed by ascites of great abundance and abdomino-pelvic pain. On histological examination, the diagnosis of yolk sac tumor in its pure and polyvesicular vitelline pattern was made. Through this observation, we propose to discuss the anatomoclinical particularities of these tumors by emphasizing the importance of histology for the diagnosis as well as the need of an early and appropriate management.

原发性腹壁肿瘤的微创手术治疗

原发性腹壁肿瘤约占所有软组织肿瘤的10%,根据其生物学行为可分为良性、恶性、交界性三种。不同类型的腹壁肿瘤在临床表现、病理特征和预后上存在显著差异。术前多学科团队的综合评估,包括病理学和影像学检查,对于制定个体化治疗方案至关重要。近年来,腹腔镜手术在腹壁肿瘤的切除和重建方面展现出诸多优势,尤其适用于深在和内生性肿瘤。相比传统开放手术,腹腔镜手术有效减少组织损伤,提高肿瘤切除的精准性,降低并发症发生率,加速病人术后恢复,并改善术后美容效果。然而,腹腔镜手术在腹壁肿瘤治疗中的长期疗效和适用范围仍需进一步的临床研究证实。

不同评分系统对消化道和腹壁肿瘤患者ICU病死率评估的比较

目的评价序贯器官衰竭评分(SOFA)、简化急性生理评分Ⅱ(SAPS-Ⅱ)、牛津急性疾病严重程度评分(OASIS)、Logistic器官功能障碍评分(LODS)、急性生理学评分Ⅲ(APS-Ⅲ)和终末期肝病模型(MELD)评分对重症监护病房(ICU)消化道和腹壁肿瘤患者死亡风险的预测效能。方法比较符合入选标准的美国重症监护医学信息数据库Ⅲ(MIMIC-Ⅲ)数据库中消化道和腹壁肿瘤患者存活组和死亡组患者的特征,绘制受试者工作特征曲线(ROC曲线),并通过计算ROC曲线下面积(AUC)评估上述评分系统对消化道和腹壁肿瘤患者ICU病死率的预测效能。绘制Kaplan-Meier生存曲线分析SAPS-Ⅱ≤49分和SAPS-Ⅱ>49分患者,以及APS-Ⅲ≤68分和APS-Ⅲ>68分患者存活率的差异。结果共纳入1400例患者,其中ICU存活1233例,死亡167例。ROC曲线分析显示:SAPS-Ⅱ、APS-Ⅲ、OASIS、SOFA、LODS、MELD评分系统对消化道和腹壁肿瘤患者ICU预后均有预测价值,AUC分别为0.835、0.831、0.816、0.797、0.788、0.729,其中SAPS-Ⅱ评分的AUC最大。Kaplan-Meier生存曲线分析显示:SAPS-Ⅱ≤49分患者的ICU存活率明显高于SAPS-Ⅱ>49分者(Log-Rank检验:χ^(2)=122.87,P=0.001);APS-Ⅲ≤68分患者的ICU存活率明显高于APS-Ⅲ>68分者(Log-Rank检验:χ^(2)=146.37,P=0.001)。对于消化道和腹壁肿瘤合并脓毒症患者,SAPS-Ⅱ评分对患者ICU病死率的预测价值优于其他评分系统。结论SPAS-Ⅱ对消化道和腹壁肿瘤患者ICU病死率的预测效能较高。
