A Pancreatic Tumour Presenting as a Ruptured Spleen

We report a case of spontaneous rupture of the spleen due to invasion from a pancreatic tumour. We are unaware of any similar case having been reported in the literature.     

A Ruptured Gastrointestinal Stromal Tumour of the Transverse Mesocolon: a Case Report

We discuss the long history of a patient still alive with a primary gastrointestinal stromal tumour (GIST) of the transverse mesocolon: initially it presented as an acute complication, namely a haemorrhagic shock caused by rupture of the tumour and it recurred twice locally in the years following primary resection. Each time, a macroscopical-ly complete resection could be achieved. Six years after the resection of the primary tumour, a liver metastasis was discovered, which was removed by radio frequency ablation (RFA). Eight months later, the patient developed a new liver metastasis and a retropancreatic mass deemed unresectable. He is treated with imatinib mesylate (Glyvec®, Novartis, Vilvoorde, Belgium) since and has had a stable disease for 6 months.

Gastrointestinal stromal tumours outside the gastrointestinal tract are rare. Until a few years ago the only possible therapy was surgical resection. Nowadays radio frequency ablation can be a solution for irresectable liver metastases, and imatinib mesylate can bring improvement for advanced and metastasized tumours. Whether this could also be useful as an adjuvant therapy has not yet been investigated, but it could be important knowing that 38% of the tumours recur locally and 15% metastasize.

The most important prognostic factors for gastrointestinal stromal tumours are grading and complete resection.     

胃肠道间质瘤

为分析胃肠道间质瘤（ＧＳＴ）的临床特点，对我院近８年来收治的３９例ＧＳＴ患者进行了回顾性分析。结果显示：本组病例平均发病年龄为４６岁，男２１例，女１８例。发生部位分布为：胃１５例（３８．５％），小肠１７例（４３．６％），十二指肠４例（１０．３％），结肠３例（７．７％）。３９例均经外科手术治疗，病理组织学显示良性３１例（７９．５％），不确定型５例（１２．８％），恶性３例（７．７％）。最常见的临床症状为胃肠出血，其中１０％的患者需紧急手术治疗。随访时间平均３年，随访期间６例患者死亡，３例死于与肿块无关的心脑疾患，７例复发，其中５例远处转移。７例局部复发或远处转移患者经再次或多次手术，配合化疗，４例存活或带瘤存活０．５～８年。结果表明：对此类肿瘤，手术宜扩大切除，术后密切随访。对复发或远处转移的病人，不要轻易放弃治疗，应持积极态度，经多次姑息切除，并辅以化疗，可望延长病人生存期。

Enteritis Cystica Profunda Presenting as Ileoileal Intussusception in a Child: Report of a Case

We report the case of a 3-month-old male infant with small bowel intussusception caused by enteritis cystica profunda (ECP). The baby was admitted because he was refusing to feed, and was passing redcurrant jelly -like stools. A palpable mass was identified, and abdominal ultrasonography showed a mass with a lumen and lumen appearance. We performed laparotomy and resected the segment of bowel containing the mass. The resected segment had enteritis cystica profunda, which was considered to have precipitated the intussusception. A review of the English medical literature revealed only three other cases of children with similar symptoms in the last 30 years.     

Laparoscopic Management of Gastrointestinal Stromal Tumours

Gastrointestinal stromal tumours (GISTs) represent the most common non-epithelial tumour of the digestive tract. Laparoscopic approach may be considered ideal for the resection of these tumours. Their particular biological behaviour allows for a curative resection even without large resection margins and extensive lymphadenectomies. Method: Over a period of five years, eight patients benefited from laparoscopic resections (six patients with primary gastric GIST and two patients with small bowel GIST). Pathological features were analyzed including tumour size, surgical margin status, immunohistochemical staining profile, and tumour mitotic index. All cases were confirmed GISTs by immunohistochemical staining.

Results: The mean age of the patients was 61.6 years (range 48–71years). Of these patients, five initially presented to hospital with acute gastrointestinal haemorrhage (four cases) or occult bleeding (one case). Gastric or small bowel tumours were identified during subsequent investigation. A presumptive diagnosis of gastric GIST was made in gastric lesions based on endoscopic, ultrasonic, and CT scan characteristics. Small bowel tumours were identified and presumed to be GIST based on information gathered from video capsule endoscopy, enteroscopy and CT scan. Complete resection was obtained with laparoscopic approach in six cases, while in two cases resection was laparoscopically assisted, with added oncology safety margins as preoperative definitive diagnosis was not available. Tumours varied in dimension from 2.5cm to 9 cm and their malignant risk score using Fletcher criteria was low in three cases, intermediate in three cases and high in two cases. Mean postoperative stay was 3.8 days and there were no complications, nor postoperative mortality. After a mean follow-up of 26 months (range 1 to 60 months) all patients are symptom free and free of recurrent disease.

Conclusions: A selective approach to laparoscopic resection of gastro-intestinal GISTs allows safe resection and very good results, on the condition that a clear diagnosis of GIST has been established on preoperative assessment. The laparoscopic feasible and safe considering the biological particularities of GIST, and it carries no additional risks.     

胃肠道间质瘤的临床分析

目的探讨胃肠道间质瘤的临床诊断与治疗。方法回顾性分析95例胃肠道恶性间质瘤病人的临床资料。结果发生于胃、小肠、结直肠、肠系膜、大网膜的病例分别为65、25、2、2、1例；肿瘤直径1～10cm；其中恶性者47例，良性者48例；行根治性切除62例，行切除术31例，2例广泛转移者行肝结节活检。17例术后发生伤口感染，免疫组化指标：CD117、CD34、CK、EMA、S-100及Desmin阳性率分别为89．5％、86．3％、5．3％、0、9．5％及8．4％。随访80例，2例胃间质瘤广泛转移者分别于术后4月、6月死亡，17例术后5～25月死于其他疾病，余者均无瘤生存，5年生存率43．7％。结论提高对胃肠道间质瘤的认识，强化术中病理学检查及免疫组化检查，确定良恶性及恶性程度，采取合理规范的手术方式，对预后及防止复发有一定意义。     

Appendiceal Intussusception Masquerading as an Ileocolic Intussusception

Introduction  

Appendiceal intussusception is rare occurring with an incidence of 0.1%. It is most commonly encountered in middle-aged females due to endometrial involvement of the appendix.     

Synchronous Jejunal Metastasis Presenting as Intussusception in a Case of Advanced RCC: a Rare Presentation

Renal cell carcinoma (RCC) may metastasize to almost any organ, but metastasis to the small bowel is very rare. Factors responsible for a resistant behavior of small bowel wall are still not clear. Small bowel metastasis from RCC may cause obstruction, bleeding, and perforation. RCC metastasis to the small bowel presenting as intussusception is extremely rare. Only 20 cases of small bowel intussusceptions caused by metastatic RCC have been reported worldwide. Here, we are reporting this rare case of RCC with simultaneous solitary metastasis in jejunum which presented as intussusceptions and which was treated with simultaneous radical nephrectomy, jejunal resection, and anastomosis.     

Surgical Therapy for Gastrointestinal Stromal Tumours of the Upper Gastrointestinal Tract

Aim  This study aimed to examine clinicopathological features and outcomes after primary resection of gastrointestinal stromal tumours (GIST) of the upper gastrointestinal tract Method  Fifty consecutive patients were identified as having a mesenchymal tumour of the upper gastrointestinal tract resected at our institution, of which 47 were GISTs. The influence of clinicopathological variables on disease-free survival was evaluated using Kaplan–Meier estimates and Cox hazard model. Results  The median age was 62.8 (21.3–94.7). The commonest presenting symptoms were anaemia (43%) and pain (34%). Tumours were located in the stomach (64%), small bowel (34%) and oesophagus (2%). Median follow-up was 20.4 (2–106) months. Fletcher low/intermediate-risk tumours had a significantly better (p = 0.0008) 2- and 5-year actuarial survival of 100% compared with 88% and 58% for high-risk group. Recurrence-free survival at 2 and 5 years was 100% for low/intermediate-risk group compared with 68% and 45% for the high-risk group (p = 0.0008). Univariate analysis of predictors of recurrence identified male sex, high mitotic rate and tumour size as significant. Multivariate analysis showed high mitotic rate as the only poor prognosticator (Hazard ratio = 16.7, p = 0.02). Conclusion  Surgical excision of low- and intermediate-grade GIST has an excellent prognosis. Surgery remains the mainstay of treatments, and high-grade tumours carry a significantly worse prognosis. High mitotic rates are an independent poor prognosticator.
