Clinical and Pathological Characterization of Lynch-Like Syndrome.

Background & Aims: Lynch syndrome is characterized by DNA mismatch repair (MMR) deficiency. Some patients with suspected Lynch syndrome have DNA MMR deficiencies but no detectable mutations in genes that encode MMR proteins-this is called Lynch-like syndrome (LLS). There is no consensus on management of patients with LLS.

Evaluation of the short- and long-term effectiveness and safety of fully covered self-expandable metal stents for drainage of pancreatic fluid collections: results of a Spanish nationwide registry.

Background And Aims: Initial reports suggest that fully covered self-expandable metal stents (FCSEMSs) may be better suited for drainage of dense pancreatic fluid collections (PFCs), such as walled-off pancreatic necrosis. The primary aim was to analyze the effectiveness and safety of FCSEMSs for drainage of different types of PFCs in a large cohort. The secondary aim was to investigate which type of FCSEMS is superior.

Flexible single-incision surgery: a fusion technique.

Introduction: The development of natural orifice transluminal endoscopic surgery has led to other techniques, such as single-incision surgery. The use of the flexible endoscope for single-incision surgery paves the way for further refinement of both surgical methods.

Objective: To describe a new, single-incision surgical technique, namely, flexible single-incision surgery.

Prospective randomized clinical trial comparing laparoscopic cholecystectomy and hybrid natural orifice transluminal endoscopic surgery (NOTES) (NCT00835250).

Background And Study Aims: Natural orifice transluminal endoscopic surgery (NOTES) is a technique still in experimental development whose safety and effectiveness call for assessment through clinical trials. In this paper we present a three-arm, noninferiority, prospective randomized clinical trial of 1 year duration comparing the vaginal and transumbilical approaches for transluminal endoscopic surgery with the conventional laparoscopic approach for elective cholecystectomy.

Patients And Methods: Sixty female patients between the ages of 18 and 65 years who were eligible for elective cholecystectomy were randomized in a ratio of 1:1:1 to receive hybrid transvaginal NOTES (TV group), hybrid transumbilical NOTES (TU group) or conventional laparoscopy (CL group).

Antral localization worsens the efficacy of enteral stents in malignant digestive tumors.

Background And Aims: Malignant gastric outlet obstruction can be treated by means of enteral stenting or surgical gastrojejunalanatomosis. We evaluated in a prospective and multicentre study the efficacy of the enteral stent on food intake, the quality of life impact, and the relationship between efficacy and determined clinical and technical parameters.

Patients And Methods: Seventy one patients affected by symptoms arising from gastroduodenal obstruction due to malignant tumors, with criteria of irresecability, metastatic disease or very high surgical risk, were treated by means of self expanding metal stents.

Emergency transvaginal hybrid natural orifice transluminal endoscopic surgery.

In a clinical series, 10 consecutive female patients with intra-abdominal infections were successfully treated with natural orifice transluminal endoscopic surgery (NOTES) performed transvaginally. The surgery, which consisted of a hybrid NOTES procedure using a transvaginal approach, was performed on an emergency basis by the surgical team on call. The indications for surgery were acute cholecystitis (n = 6), acute appendicitis (n = 2), and pelvic peritonitis (n = 2) with intra-abdominal infection.

Hybrid natural orifice transluminal endoscopic cholecystectomy: prospective human series.

Background: Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. Currently, it is not possible to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids fusing minilaparoscopy and transluminal endoscopic surgery. This report presents a prospective clinical series of 25 patients who underwent transvaginal hybrid cholecystectomy for cholelithiasis.

[Non-randomised, comparative, prospective study of transvaginal endoscopic cholecystectomy versus transparietal laparoscopic cholecystectomy].

Introduction: We present a non-randomised comparative study of two patients series followed up prospectively, in which convention laparoscopic cholecystectomy is compared with transvaginal cholecystectomy, a hybrid transluminal endoscopic procedure, with the objective of assessing the clinical safety of the procedures and its efficacy in the resolution of cholelithiasis.

Patients And Method: A non-randomised prospective clinical series of 40 female patients, operated on for cholelithiasis using endoscopic surgery, 20 with a conventional laparoscopic approach and 20 using a transvaginal endoscopic approach. Surgical wound infection, urinary infection, evisceration, eventration, mortality and other complications.

Primary monophasic synovial sarcoma of the duodenum confirmed by cytogenetic analysis with demonstration of t(X;18): a case report.

Synovial sarcoma (SS) is an uncommon malignant neoplasm of the soft tissues. It mainly affects the periarticular tissues of the extremities in young adults, but has been described at nearly all sites; nevertheless, the gastrointestinal tract is an exceptional location. We report a case of a primary synovial sarcoma of the duodenum in a 69-year-old woman.

Hybrid transvaginal cholecystectomy, NOTES, and minilaparoscopy: analysis of a prospective clinical series.

Introduction: Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. It is not yet possible to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids, a fusion of minilaparoscopy and transluminal endoscopic surgery. In this paper we present a prospective clinical series of 15 patients who underwent transvaginal hybrid cholecystectomy for cholelithiasis.

Transvaginal liver resection (NOTES) combined with minilaparoscopy.

Objective: to report on the first liver resection performed on a human being by a transvaginal NOTES approach combined with minilaparoscopy.

Patients And Methods: a sixty-one-year-old woman with a history of Wertheim s hysterectomy for endometrial carcinoma 10 years ago, and malignant melanoma correctly treated in 2006, had suspected segment-V liver metastasis near the gallbladder by CT-scan and MRI. The indication for a laparoscopic approach was made, and a combined transvaginal and minilaparoscopic resection was offered and accepted by the patient.

[Transvaginal cholecystectomy (NOTES) combined with minilaparoscopy].

Objective: To report on the first transvaginal cholecystectomy performed on a human being in Spain.

Patients And Methods: A 35-year-old female with a history of recurrent bouts of biliary pain resulting from gallstones. A surgical procedure was performed by a multidisciplinary team composed of surgeons, gastroenterologists, and gynecologists.

Drug-induced hepatitis superimposed on the presence of anti-SLA antibody: a case report.

Introduction: Autoimmune hepatitis is a necroinflammatory disorder of unknown etiology characterized by the presence of circulating antibodies, hypergammaglobulinemia, and response to immunosuppression. It has the histological features of chronic hepatitis. The onset is usually insidious, but in some patients the presentation may be acute and occasionally severe.

[Ulcerative colitis with segmental involvement].

Introduction: Ulcerative colitis is a chronic inflammatory disease affecting areas of the colon or the full length. From the endoscopic point of view, ulcerative colitis presents lesions that stretch continuously from the rectum to variable colon segments, a characteristic that is of great value when distinguishing it from Crohn's disease. Continuous involvement, without healthy patches, justifies ending endoscopic exploration once the distal end of the lesion has been reached.

The effect of repetitive magnetic stimulation on localized musculoskeletal pain.

Current magnetic coil stimulators can efficiently activate neural structures without deep electrode placement and the local discomfort associated with transcutaneous electrical stimulation used in pain control. We tested the possibility of reducing pain in patients with localized musculoskeletal processes by applying repetitive magnetic stimulation on the tender body region. Thirty patients were randomized to receive 40 min of real or sham magnetic stimulation.

[Energy expenditure of patients with Crohn's disease. Course study during hospitalization].

Weight loss and protein energy malnutrition are frequent in Crohn's disease. The increase of resting energy expenditure has been pointed out as the cause of these findings. In this study we report eleven patients with Crohn's disease, six women and five men hospitalized with active Crohn's disease.

[Energy consumption in patients with Crohn's disease. An evolutionary study during hospitalization].

In Crohn's disease, weight loss and malnutrition are very frequently occurring problems. One explanation of these findings could be an increased energy expenditure. Eleven patients were studied, of which six were women and five were men, during a hospital stay for an active episode of Crohn's disease.

[A prospective study of the functioning of 2 types of enteral nutrition catheters].

The problems of disintubation and obstruction of nutritional catheters are common during treatment with enteral nutrition. This prospective study has been designed to evaluate the differences in the frequency of obstruction between two different types of enteral nutrition catheter. Catheter A (Silk, Ibys) with one single lateral outlet, wide, long and with a curved edge, and Catheter B (Nutrisoft M, Kabi-Pfrimmer), with several smaller lateral holes, 46 nutritional periods were studied, divided into two groups: first group, n = 32 (catheter A) and second group n = 14 (catheter B, Nutrisoft M, Kabi-Pfrimmer).

Ascites increases the resting energy expenditure in liver cirrhosis.

The purpose of this study was to investigate the effect of ascites on the energy metabolism of patients with liver cirrhosis. The resting energy expenditure was determined in 10 patients with liver cirrhosis and ascites of moderate or large volume. The resting energy expenditure measurement was performed using indirect calorimetry and the resting energy expenditure predictive value was calculated with the Harris-Benedict equation, both before and after removal of ascitic fluid by paracentesis.
