Match detection analysis on SentiMag® system and standard technique in SLNB of breast cancer.

Introduction: In breast cancer surgery, there are techniques for sentinel lymph node biopsy (SLNB) that do not require Nuclear Medicine, such SentiMag®, which uses ferromagnetic particles. The main purpose of this analysis is to study the degree of concordance in SLNB between SentiMag® and the standard method (Tc99 radiotracer). The secondary objective is to identify factors that impact in sentinel node detection rate and matching detection rate between both probes.

[Colorectal stents: efficacy and complications in our center].

Background: in emergency surgery, colorectal mortality is very high compared with elective surgery. An alternative is placement of endoscopic stents to correct the bowel obstruction and then allow elective surgery. Moreover, it is possible to use stents in the palliative treatment of patients at high surgical risk or with unresecable tumors.

Protective ileostomy: complications and mortality associated with its closure.

Introduction: diverting loop ileostomies are widely used in colorectal surgery to protect low rectal anastomoses. However, they may have various complications, among which are those associated with the subsequent stoma closure. The present study analyses our experience in a series of patients undergoing closure of loop ileostomies.

Gastrointestinal bleeding and bowel obstruction as a presentation of Bouveret syndrome.

Background: Bouveret syndrome is a rare entity consisting of duodenal obstruction due to a gallstone from the gallbladder.

Clinical Cases: We present two patients with very different ages and comorbidities whose conditions were resolved in two different ways: a 41-year-old female with right upper quadrant pain and vomiting who underwent surgical correction of obstruction and fistula, and an 81-year-old female with a high bowel obstruction, only treating the obstruction without intervention of the fistula.

Conclusions: It is important to include high gastrointestinal obstruction in the differential diagnosis.

Evaluation of a clinical pathway to improve colorectal cancer outcomes.

The aims of this preintervention and postintervention study were to monitor and evaluate the clinical pathway (CP) for colorectal cancer (CRC) over a 5-year period and to compare 2 groups of patients (before and after the intervention) with regard to different variables of effectiveness. Group I comprised 68 patients who underwent planned surgery between January 2002 and January 2003. Group II comprised a sample of 202 patients who underwent surgery between January 2004 and December 2008.

Unnoticed small bowel perforation as a complication of lumbar discectomy.

Background Context: Surgery for disc herniation is one of the most common traumas and neurosurgical procedures. Although discectomy has low morbidity, serious intra-abdominal complications can affect retroperitoneal structures, such as the large vessels, small intestine, and ureters.

Case Report: A 36-year-old woman in uncontrollable pain presented with left sciatic neuralgia in the L5 region.

Repair of complex incisional hernias using double prosthetic repair: single-surgeon experience with 50 cases.

Background: The treatment of complex incisional hernias is still difficult and controversial. With technologic developments we can modify and update the operative techniques described for treating complex abdominal wall hernias.

Methods: This is a prospective study of 50 patients with complex incisional hernias undergoing complex abdominal wall herniorrhaphy at a university hospital.

Treatment of incisional hernias adopting an intra-abdominal approach with a new low-density composite prosthetic material: proceed: our preliminary experience on 50 cases.

Introduction: The management of incisional hernias remains a challenge for the general surgeon. Repairing by using prosthetic materials has reduced the relapse rate, but intra-abdominal mesh placement continues to be a source of controversy.

Objective: An evaluation is made of the results of treating incisional hernias with a new intra-abdominal low-density composite mesh through both the open and the laparoscopic approach.
