Laparoscopy management for spontaneous bladder rupture: a case report.

We present a case of a 79-year-old man with lower abdominal pain and negative Blumberg sign. An indwelling bladder catheter was inserted for urinary retention due to a tight phimosis 2 months earlier. A contrast-enhanced computed tomography scan revealed a huge gastrectasia and small bowel distention due to a suspected adherent bridle.

Suzuki-Miyaura Micellar One-Pot Synthesis of Symmetrical and Unsymmetrical 4,7-Diaryl-5,6-difluoro-2,1,3-benzothiadiazole Luminescent Derivatives in Water and under Air.

The Suzuki-Miyaura cross-coupling reaction of 4,7-dibromo-5,6-difluoro-2,1,3-benzothiadiazole with different arylboronic acids can be efficiently carried out in water and under air by means of micellar coupling. The careful tuning of reaction conditions enables preparation of symmetrically and unsymmetrically substituted derivatives. The moderate to good yields obtained, along with the wide variety of available substitution patterns, makes this sustainable methodology very useful for the preparation of building blocks for luminescent optoelectronic materials.

Cricopharyngeal myotomy with thulium laser through flexible endoscopy: proof-of-concept study.

Background And Study Aims: Endoscopic treatment of Zenker's diverticulum has proven feasible, but electrocautery and CO laser technology carry the risk of collateral thermal injury. Thulium laser septum incision may overcome this limitation. We describe for the first time the use of thulium laser through flexible endoscopy in a small cohort of patients with Zenker diverticulum.

Stent-in-stent, a safe and effective technique to remove fully embedded esophageal metal stents: case series and literature review.

Background: Endoscopic stenting is a widely used method for managing esophageal anastomotic leaks and perforations. Self-expanding metal stents (SEMSs) have proved effective in sealing these defects, with a lower rate of displacement than that of self-expanding plastic stents (SEPSs) as a result of tissue proliferation and granulation tissue ingrowth at the uncovered portion of the stent, which anchor the prosthesis to the esophageal wall. Removal of a fully embedded stent is challenging because of the risk of bleeding and tears.

Laparoscopic surgery in rectal cancer: a prospective analysis of patient survival and outcomes.

Purpose: The role of laparoscopic resection in the management of rectal cancer is still controversial. We prospectively evaluated patient survival and outcomes in patients undergoing laparoscopic rectal resection for rectal cancer at a single institution.

Methods: From November 1999 to November 2005, 107 patients with rectal cancer were treated by laparoscopy.

Laparoscopic lymphatic mapping and sentinel lymph node detection in colon cancer: technical aspects and preliminary results.

Background: The utility of lymph node mapping to improve staging in colon cancer is under evaluation. Laparoscopic colectomy for colon cancer has been validated in multicentric trials. This study assessed the feasibility of lymph node mapping in laparoscopic colectomy for colon cancer.

[Laparoscopic surgery of colon cancer. State of art and literature review].

Over the past decade advances in laparoscopic surgery have revolutionized the surgical approach to many diseases. Although the first case series on laparoscopic segmental colectomy in patient with sigmoid cancer was described in 1991, this technique has not been readily accepted. Despite reduced morbidity and improved convalescence after laparoscopic surgery for benign disorders, surgeons have been sceptical about similar advantages of laparoscopic colectomy for cancer.

A prospective comparison of endorectal ultrasound and pelvic magnetic resonance in the preoperative staging of rectal cancer.

Background: The development of new surgical modalities (local excision, coloanal-anastomosis) and the diffusion of preoperative neoadjuvant therapy, has increased the importance of an accurate preoperative staging in patients with rectal cancer. The aim of this study was to compare the accuracy of endoscopic ultrasound (EUS) and magnetic resonance imaging (MRI) in the local preoperative staging of rectal carcinoma; moreover the two methods were assessed with a concordance K test.

Methods: Twenty-nine patients with rectal carcinoma were staged with EUS and body coil MRI and then underwent radical surgery.

Endoscopic ultrasonography and magnetic resonance in preoperative staging of rectal cancer: comparison with histologic findings.

The development of new surgical techniques and use of neoadjuvant therapy have increased the need for accurate preoperative staging of rectal cancer. We compared the ability of endoscopic ultrasonography (EUS) and two magnetic resonance imaging (MRI) coils to locally stage rectal carcinoma before surgery. Forty-nine patients with histologically proven rectal carcinoma were T and N staged by EUS and either body coil MRI or phased-array coil MRI.
