BACKGROUND AND AIMS: The colonic self-expanding metal stent (SEMS) has been widely used for "bridge to surgery" and palliative therapy. However, if the spread of SEMS is insufficient, not only can a decompression effect not be obtained but also perforation and obstructive colitis can occur. The mechanism of occurrence of obstructive colitis and perforation was investigated by flow dynamics. METHODS: Bernoulli's principle was applied, assuming that the cause of inflammation and perforation represented the pressure difference in the proximal lumen and stent...

BACKGROUND Adenocarcinoma of the colon frequently invades adjacent organs, spreads intraperitoneal, and metastasizes to intestinal lymph nodes, lungs, and the liver. Metastasis solely to the extrahepatic bile duct is extremely rare and has only been previously reported on 15 occasions. The accurate determination that an extrahepatic common bile duct lesion is of colonic origin has critical therapeutic implications. CASE REPORT The patient was a 50-year-old male with a history of colon cancer S/P surgical resection in September 2014...

BACKGROUND: Ureteral injuries during colorectal surgery are a rare event, ranging in the literature from 0.28-7.6%. Debate surrounds the use of prophylactic lighted ureteral stents to help protect the ureter during laparoscopic surgery. It has been suggested that they help to identify injuries but do not prevent them. The authors look to challenge this. METHODS: Over 66 months, every laparoscopic or colectomy involving ureteral stents was recorded. Researchers documented any injury to the ureter intraoperatively...

REVIEW
Diane Mege, Yves Panis
BACKGROUND: In patients with ileo-colonic Crohn's disease (CD), the main consequence of the development of intestinal fibrosis is the occurrence of a localized symptomatic stenosis for which treatment is mandatory. Besides medical treatment, which is still considered to be ineffective against non-inflammatory fibrotic intestinal stenosis due to CD, there are 2 options for the treatment of such stenosis: endoscopic and surgical approaches. Key Messages: Endoscopic treatment includes balloon dilatation and stenting, and can be performed only on selected patients with very short stenosis...

A man in his 60s underwent gastrectomy to treat gastric carcinoma. Approximately 2.5 years after the surgery, he was admitted to the hospital because of abdominal pain. He was diagnosed with obstruction of the transverse colon due to a colon tumor. A stent was placed to treat the obstruction and avoid oncologic emergency. Biopsy results and imaging showed that the patient did not have colon cancer, but his previous gastric cancer had disseminated peritoneally. Chemotherapy was selected as treatment for recurrent gastric cancer...

There are several reasons for failure in the insertion of a self-expandable metallic stent(SEMS)into a malignant colonic obstruction(MCO)including difficulty in insertion of the catheter or guidewire through the stenotic lumen into the oral side or perforation relatedto the technique. Herein, we report a case of MCO bearing another synchronous obstructive lesion in the anal side of the colon that couldhave explainedthe difficulty in the insertion of the SEMS into the stenosis locatedin the oral side, which might have indicated the need for an emergency operation for relieving the obstruction...

We report a case of locally far-advanced colon cancer resected by laparoscopic surgery after colonic stent insertion and neoadjuvant chemotherapy. A 71-year-old man with obstructive symptoms was admitted to our hospital in July 2015. CT revealed a sigmoid colon tumor infiltrating the retroperitoneum and small intestine. Lower gastrointestinal endoscopy showed a sigmoid colon cancer. Self-expandable metallic stent insertion for obstructive colon cancer alleviated the patient's symptoms quickly. Four courses of neoadjuvant chemotherapy(XELOX)reduced the primary tumor in size, allowing for laparoscopic surgical resection...

A66 -year-old woman presented with abdominal pain and nausea. She was diagnosed with wall thickening of the gastric antrum and bowel obstruction caused by tumors of the splenic flexure on computed tomography. Aself -expandable metallic stent(SEMS)was placed in the splenic flexure of the colon 4 days after transanal ileus tube replacement. No complication was observed, and she could ingest a normal diet, permitting her discharge from the hospital 12 days after SEMS placement. She was diagnosed with gastric cancer(Type 4, cT4a[SE], N2, H0, P1, M1[LYM], cStage IV )on upper gastrointestinal endoscopy and computed tomography, and administration of S-1 plus oxaliplatin(SOX)was started...

A 65-year-old man had been receiving hemodialysis for chronic renal failure. We diagnosed colonic ileus with transverse colon cancer and synchronous multiple liver metastases(liver segments 4 and 6)based on symptoms of abdominal pain and distension. After stent placement in the region of the colonic stenosis, left hemicolectomy was performed for transverse colon cancer. After surgery, the patient received capecitabine plus oxaliplatin(CapeOX)therapy. The dose of capecitabine was 1,250mg/m2, and the dose of oxaliplatin was 70 mg/m2 until the second course, after which it was increased to 100 mg/m2 for the third course...

Herein, we report 3cases of unresectable, advanced, and recurrent colorectal cancer associated with gastrointestinal obstruction. The patients were treated with small intestine-transverse colon bypass surgery, which improved the quality of life (QOL)in all cases. Case 1 was an 80-year-old woman who presented with subileus due to ascending colon cancer. After surgery, her oral intake was reestablished, and she was discharged home. Case 2 was an 89-year-old woman whose ileus was caused by cecal cancer with multiple hepatic metastases...

We report 2 cases of obstructive colorectal cancer that were successfully treated with a self-expanding metallic stent (SEMS). They were both diagnosed with obstructive colorectal cancer. Colonoscopy was performed to make a definitive and qualitative diagnosis and to relieve the stenosis using a SEMS. The SEMSs were inserted without complications. A few days later, the patients underwent laparoscope-assisted sigmoidectomy with lymph node resection. Despite the colon obstruction, a primary anastomosis was performed...

From September 2013 to February 2015, 14 patients with ileus associated with colorectal cancer underwent surgeryafter applying a self-expandable metal stent in our department. Twelve were left-side colon ileus patients and 2 were right-side colon ileus patients. The technical success rate of the stent insertion was 100%. One patient experienced complications(stent occlusion). All patients were able to eat, and 9 of them were able to leave the hospital temporarilybefore the operation. All patients with left-side colon ileus had their oral-side intestine evaluated before the operation...

OBJECTIVES: Evaluation of complex, acquired, non-malignant tracheo/broncho-oesophageal fistulas (TEF) repaired by extrathoracic pedicled muscle flaps that were, in addition to their interposition between the airways and the gastro-intestinal tract, patched into gastro-intestinal or airway defects if primary closure seemed risky. METHODS: A single institution experience of patients treated between 2003 and 2015. Twenty-two patients required TEF repair following oesophageal surgery (18), Boerhaave syndrome (1), chemotherapy for mediastinal lymphoma (1), carinal resection and irradiation (1) and laryngectomy (1); 64% of them underwent prior radio- or chemotherapy and 50% prior airway or oesophageal stenting...

INTRODUCTION: Biliary stent migration (proximal or distal) occurs in 6% of all cases. The majority of these migrating stents are passing through the intestine, without causing any complications. Usually when a stent migration occurs, endoscopic retrieval is the proper treatment option, except in case of complications when surgical removal is the only treatment option. This report presents a case of a biliary stent which migrated and caused a sigmoid colon perforation. PRESENTATION OF CASE: A 75 years old female patient presented to the emergency department with diffuse abdominal pain, nausea and vomiting...

Self-expandable metallic stent (SEMS) placement has been practiced in several hospitals in Japan, including ours, since January 2012. Here, we report the case of an 82-year-old Japanese man who presented to the hospital with a 1-week history of right hypochondrial pain. Computed tomography (CT) findings indicated colorectal cancer. The laboratory findings on admission indicated severe anemia (red blood cell count, 426 × 104/μL; hemoglobin, 7.9 g/dL). We performed SEMS placement because the patient refused to undergo surgery...
