Presacral venous bleeding during mobilization in rectal cancer.

Aim: To analyze the anatomy of sacral venous plexus flow, the causes of injuries and the methods for controlling presacral hemorrhage during surgery for rectal cancer.

Methods: A review of the databases MEDLINE and Embase™ was conducted, and relevant scientific articles published between January 1960 and June 2016 were examined. The anatomy of the sacrum and its venous plexus, as well as the factors that influence bleeding, the causes of this complication, and its surgical management were defined.

Results of colon cancer surgery in patients over 75 years old.

Background: Colon cancer is the second most frequent cause of death in both genders. Survival has increased since 1980, although this increase has been lower in patients ≥75 years old. We analyzed the results of surgical treatment for this pathology in this group of patients.

[Vacuum assisted closure in open abdomen and deferred closure: experience in 23 patients].

Introduction: We analyse our experience and the results obtained with the use of vacuum assisted closure (VAC(®), KCI Clinic Spain SL) in the management of open abdomen.

Material And Methods: We retrospectively reviewed the laparostomies performed between June 2006 and March 2011 using VAC(®) treatment in the Hospital Xeral-Cíes, Vigo.

Results: We included 23 consecutive patients (18 males and 5 females) on whom the VAC(®) was used in the open abdomen due to different indications (abdominal trauma, peritonitis, pancreatitis, ischaemic disease or abdominal compartmental syndrome).

[Abdominoperineal resection in anal cancer: Reconstruction of the perineum with a myocutaneous flap from the anterior rectus abdominis muscle].

Introduction: Abdominoperineal resection after radiotherapy has a high rate of perineal wound complications. The aim of this retrospective study was to evaluate the results of perineal reconstruction with a rectus abdominis muscle myocutaneous flap in patients with recurrent or persistent anal cancer.

Patients And Method: Between 2006 and 2010, six male HIV+ patients were treated after initial treatment failure with chemotherapy.

[Hyperparathyroidism, goiter and well-differentiated thyroid carcinoma. A common association with diagnostic implications].

Objective: To analyze thyroid gland disease incidentally found in patients undergoing surgery for hyperparathyroidism and to compare the frequency of nonmedullary thyroid carcinoma among different hyperparathyroidism varieties.

Patients And Method: We retrospectively reviewed 124 clinical records of patients who underwent surgery for hyperparathyroidism by a single surgeon from January 1998 to June 2006.

Results: There were 105 women (84.

[Intermediate-risk gastrointestinal stromal tumor: diagnosis through hydrogastric ultrasonography].

Evaluation of submucosal lesions of the digestive tract with conventional endoscopy is unsatisfactory since this technique does not allow direct observation or correct evaluation of the size and layer of origin of the tumor; therefore, in most patients an etiological diagnosis cannot be established with this procedure. However, in most patients, endoscopic ultrasonography can resolve these problems: to a fair degree of certainty, this technique can differentiate malignant from benign lesions, measure their size, and establish their layer of origin. Endoscopic ultrasonography is the technique of choice to establish the presence and characteristics of submucosal tumors and their suitability for treatment.

[Spontaneous pneumomediastinum mimicking Boerhaave's syndrome].

Spontaneous pneumomediastinum is an uncommon benign disorder that usually occurs in young men. Because of its clinical features and physiopathologic mechanism, other, more serious disorders that could require urgent treatment, such as Boerhaave's syndrome or spontaneous esophageal rupture, must be ruled out. We report the case of a 19-year-old man with no relevant history, who presented mediastinal emphysema after an episode of repeated vomiting in the context of alcohol abuse.

Peritoneal dialysis catheter obstruction caused by Fallopian tube wrapping.

Peritoneal catheter malfunction is commonly related to omental wrapping, although entrapment owing to other different intraperitoneal structures is possible but rare. The authors report a case of catheter obstruction owing to fallopian tube wrapping, diagnosed and resolved by laparoscopic surgery. A brief review of this rare problem is presented.
