Intermittent gastric outlet obstruction due to a gallstone migrated through a cholecysto-gastric fistula:A new variant of “Bouveret’s syndrome”

Bouveret's syndrome, defined as gastric outlet obstruction due to a large gallstone, is still one of the most dramatic biliary gallstone complications. Although new radiological and endoscopic techniques have made pre-surgical diagnosis possible in most cases and the death rate has dropped dramatically, "one-stage surgery" (biliary surgery carried out at the same time as the removal of the gut obstruction) should be still considered as the gold standard for the treatment of gallstone ileus.In this case, partial gastric outlet obstruction resulted in an atypical and insidious clinical presentation that allowed us to perform the conventional one-stage laparatomic procedure that completely solved the problem, thus avoiding any further complications.     

Resolution of Crohn’s disease and complex regional pain syndrome following treatment of paratuberculosis

A cohort of family members with various chronic diseases including Crohn’s disease, asthma, complex regional pain syndrome, hypothyroidism, type 1 diabetes mellitus, and lymphangiomatosis and/or evidence of infection by Mycobacterium avium subsp. paratuberculosis(MAP) are described in this series of case reports. MAP was cultured from the blood of three members affected by the first five diseases and there was accompanying elevated anti-MAP Ig G in two members. The patient affected by the sixth disease has a markedly elevated anti-MAP titer. The two patients affected by the first four diseases have been treated with a combination of anti-MAP antibiotics and ultraviolet blood irradiation therapy with resolution of the disease symptomatology and inability to culture MAP in post treatment blood samples. These case reports of patients with MAP infections provide supportive evidence of a pathogenic role of MAP in humans.     

Colonic perforation in Behet’s syndrome

A 17-year-old gentleman was admitted to our hospital for headache, the differential diagnosis of which included Behet’s syndrome (BS). He developed an acute abdomen and was found to have air under the diaphragm on erect chest X-ray. Subsequent laparotomy revealed multiple perforations throughout the colon. This report describes an unusual complication of Behcets syndrome occurring at the time of presentation and a review of the current literature of reported cases.     

Biodegradable stent for the treatment of a colonic stricture in Crohn’s disease

Biodegradable polydioxanone stents were developed for the treatment of refractory benign esophageal strictures but have been suggested as a new therapeutic option for intestinal strictures.The primary advantage of biodegradable stents over self-expandable metallic stents is that removal is not required.There are,however,few data available on their use in the small or large bowel.We herein describe the case of a 33-yearold patient with long-standing Crohn’s disease(CD) who developed a fibrotic stricture of the sigmoid too long to be amenable to balloon dilation.The use of a biodegradable polydioxanone stent was chosen to avoid surgery.Combined endoscopic and fluoroscopic placement of the stent was technically simple,safe and clinically successful,and no recurrence of obstructive symptoms occurred during a 16-mo follow-up.Further studies are needed to evaluate the long-term efficacy and safety of biodegradable stents in the treatment of intestinal strictures,particularly in the context of CD.     

Efficacy of endoscopic therapy for gastrointestinal bleeding from Dieulafoy’s lesion

AIM: To investigate the endoscopic hemostasis for gastrointestinal bleeding due to Dieulafoy’s lesion. METHODS: One hundred and seven patients with gastrointestinal bleeding due to Dieulafoy’s lesion were treated with three endoscopic hemostasis methods: aethoxysklerol injection (46 cases), endoscopic hemoclip hemostasis (31 cases), and a combination of hemoclip hemostasis with aethoxysklerol injection (30 cases). RESULTS: The rates of successful hemostasis using the three methods were 71.7% (33/46), 77.4% ...     

Lipoma within inverted Meckel’s diverticulum as a cause of recurrent partial intestinal obstruction and hemorrhage: A case report and review of literature

Lipoma within an inverted Meckel's diverticulum presen- ting with hemorrhage and partial intestinal obstruction is an exceptional clinical entity. We report a case of 47-year-old male with a history of recurrent episodes of partial intestinal obstruction and melena due to a subserosal lipoma located in the base of an inverted Meckel's diverticulum. According to our knowledge, this is the first case of a lipoma within a Meckel's diverticulum giving rise to this clinical scenario without the existence of heterotrophic gastric or pancreatic tissues.     

Treatment of peri-anal fistula in Crohn’s disease

Anal fistulas are a common manifestation of Crohn’s disease(CD). The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently em-ployed. However, at the moment, none of these tech-niques appear superior to the others in terms of healing rate. Surgery is always indicated to treat symptomatic, simple, low intersphincteric fistulas refractory to medi-cal therapy and those causing disabling symptoms. Ut-most attention should be paid to correcting the balance between eradication of the fistula and the preservationof fecal continence.

Inverted cystic tubulovillous adenoma involving Brunner’s glands of duodenum

Benign neoplasia of the duodenum are very rare. Moreover, duodenal tubulovillous adenomas are more uncommon lesions. The microscopic structure of tubulovillous adenoma has frond-like projection of mucosa with branching papillary structure and generally upward growth into the lumen. We describe a 72-year-old man who showed aduodenal tubulovillous adenoma with unusual inverted cystic growth pattern. Interestingly, this tubulovillous adenomatous lesion was interrupted by gastric metaplasia in the deep portion of the cyst and was closely surrounded by Brunner’s glands. Although histogenesis of gastric metaplasia of duodenum is not fully understood, Brunner’s glands has been suggested as a precursor for gastric metaplasia. Therefore, these findings argued that this adenoma arises from Brunner’s glands through gastric metaplasia. This is the first case of inverted cystic tubulovillous adenoma involving Brunner’s glands of duodenum with gastric metaplasia.     

Crohn’s disease complicated by multiple stenoses and internal fistulas clinically mimicking small bowel endometriosis

We report a 31-year-old woman with Crohn's disease complicated by multiple stenoses and internal fistulas clinically misdiagnosed as small bowell endometriosis, due to the patient's perimenstrual symptoms of mechanical subileus for 3 years; at first monthly, but later continuous, and gradually increasing in severity. We performed an exploratory laparotomy for small bowel obstruction, and found multiple ileal strictures and internal enteric fistulas. Because intraoperative findings were thought to indicate Crohn's disease, a right hemicolectomy and partial distal ileum resection were performed for obstructive Crohn's ileitis. Histopathology of the resected specimen revealed Crohn's disease without endometrial tissue. The patient made an uneventful recovery from this procedure and was discharged home 10 d post-operatively. The differential diagnosis of Crohn's diease with intestinal endometriosis may be difficult pre-operatively. The two entities share many overlapping clinical, radiological and pathological features. Nevertheless, when it is difficult to identify the cause of intestinal obstruction in a woman of child-bearing age with cyclical symptoms suggestive of small bowel endometriosis, Crohn's disease should be included in the differential diagnosis.

Laparoscopic gastrojejunostomy for gastric outlet obstruction in patients with unresectable hepatopancreatobiliary cancers: A personal series and systematic review of the literature

The major symptoms of advanced hepatopancreaticbiliary cancer are biliary obstruction, pain and gastric outlet obstruction(GOO). For obstructive jaundice, surgical treatment should de consider in recurrent stent complications. The role of surgery for pain relief is marginal nowadays. On the last, there is no consensus for treatment of malignant GOO. Endoscopic duodenal stents are associated with shorter length of stay and faster relief to oral intake with more recurrent symptoms. Surgical gastrojejunostomy shows better long-term results and lower re-intervention rates, but there are limited data about laparoscopic approach. We performed a systematic review of the literature, according PRISMA guidelines, to search for articles on laparoscopic gastrojejunostomy for malignant GOO treatment. We also report our personal series, from 2009 to 2017. A review of the literature suggests that there is no standardized surgical technique either standardized outcomes to report. Most of the studies are case series, so level of evidence is low. Decisionmaking must consider medical condition, nutritional status, quality of life and life expectancy. Evaluation ofthe patient and multidisciplinary expertise are required to select appropriate approach. Given the limited studies and the difficulty to perform prospective controlled trials, no study can answer all the complexities of malignant GOO and more outcome data is needed.

Post-cholecystectomy Mirizzi��s syndrome: Magnetic Resonance Cholangiopancreatography Demonstration

A long cystic duct remnant may be found after laparoscopic cholecystectomy. Stone may form in the remnant cystic duct and can cause postcholecystectomy syndrome. Remnant cystic duct calculus may rarely result in postcholecystectomy Mirizzi’s syndrome. Traditionally, Mirizzi’s syndrome has been diagnosed with endoscopic retrograde cholangiopancreatography (ERCP) and treated with open surgery. We report a case of postcholecystectomy Mirizzi’s syndrome that developed 3 years after laparoscopic cholecystectomy. A non-invasive diagnosis of Mirizzi’s syndrome was made comprehensively by magnetic resonance cholangiopancreatography. Endoscopic stone removal was achieved successfully with ERCP without any complication.     

Meckel＇s diverticulum manifested by a subcutaneous abscess

This case report describes an extremely rare complication of a Meckel's diverticulum: enterocutaneous fistula of the diverticulum. The presence of Meckel's diverticulum is a well known entity, but subcutaneous perforation of the diverticulum is very rare. Here we report the case of a patient with the complaint of a right lower quadrant abscess, preoperatively diagnosed as enterocutaneous fistula, which was determined intraoperatively to be a fistula resulting from Meckel's diverticulum.     

Laparoscopic transhiatal approach for resection of an adenocarcinoma in long-segment Barrett's esophagus

Barrett's esophagus(BE) is a precursor of esophageal adenocarcinoma and is associated with gastroesophageal reflux disease, which is often preceded by a hiatal hernia. We describe a case of esophageal adenocarcinoma arising in long-segment BE(LSBE) associated with a hiatal hernia that was successfully treated with a laparoscopic transhiatal approach(LTHA) without thoracotomy. The patient was a 42-year-old male who had previously undergone laryngectomy and tracheal separation to avoid repeated aspiration pneumonitis. An ulcerative lesion was found in a hiatal hernia by endoscopy and superficial esophageal cancer was also detected in the lower thoracic esophagus. The histopathological diagnosis of biopsy samples from both lesions was adenocarcinoma. There were difficulties with the thoracic approach because the patient had severe kyphosis and muscular contractures from cerebral palsy. Therefore, we performed subtotal esophagectomy by LTHA without thoracotomy. Using hand-assisted laparoscopic surgery, the esophageal hiatus was divided and carbon dioxide was introduced into the mediastinum. A hernial sac was identified on the cranial side of the right crus of the diaphragm and carefully separated from the surrounding tissues. Abruption of the thoracic esophagus was performed up to the level of thearch of the azygos vein via LTHA. A cervical incision was made in the left side of the permanent tracheal stoma, the cervical esophagus was divided, and gastric tube reconstruction was performed via a posterior mediastinal route. The operative time was 175 min, and there was 61 m L of intra-operative bleeding. A histopathological examination revealed superficial adenocarcinoma in LSBE. Our surgical procedure provided a good surgical view and can be safely applied to patients with a hiatal hernia and kyphosis.

PCI术后双联抗血小板治疗致上消化道出血的预防与治疗

经皮冠状动脉介入术（PCI）后,接受阿司匹林和波立维双联抗血小板治疗已经成为预防支架内血栓形成的标准化治疗。在置入药物涂层支架（DES）后由于支架内皮化进程缓慢,服用双联抗血小板药物甚至要长于24个月。据统计,我国2008年进行PCI术患者约为16万,2009年预计将超过20万。由于行PCI术患者数日庞大,术后服用双联抗血小板治疗带来的副作用,
