Short-term outcome of percutaneous posterior tibial nerve stimulation (PTNS) for the treatment of faecal incontinence.

BACKGROUND: The aim of the present study was to establish the efficacy of percutaneous posterior tibial nerve stimulation (PTNS) in treating flatal, urge and passive faecal incontinence (FI). METHODS: A prospective study with 55 patients with FI was carried out. Clinical anamnesis, physical examination, a reverse visual analogue scale (VAS) score, Wexner score and the American Society of Colon and Rectal Surgeons quality of life score were recorded at baseline and 6 months, along with an incontinence diary. Subjects underwent one weekly session for 12 consecutive weeks and then continued with six additional fortnightly sessions. An intention-to-treat analysis was performed. RESULTS: Fifty-five patients (44 females; mean age 58.62 ± 10.74 years) with FI were treated with PTNS. The origins of the incontinence were obstetric (52.7 %) and perineal surgery (34.5 %). Eight patients did not continue with the second stage of treatment. The median Wexner baseline value was 9.98. After 6 months, it had decreased to 4.55 (p < 0.001). The visual analogue scale (VAS) increased from 4.94 to 6.80 (p < 0.001). There was a significant improvement in lifestyle, coping/behaviour, depression/self-perception and embarrassment scores. With respect to different types of FI, there was an improvement in the Wexner score both in patients with true passive FI and in those with urge or mixed FI. CONCLUSIONS: PTNS is an effective treatment for FI. Patients with passive or urge FI can benefit from this therapy, with improvement of the Wexner score and quality of life variables.

[Omental torsion: imaging techniques can prevent unnecessary surgical interventions]. / Torsión de epiplón: las técnicas de imagen pueden evitar intervenciones innecesarias.

INTRODUCTION: Segmentary infarction of the greater omentum produces a clinical profile of acute abdomen. To date, the cause has been discovered during surgery. Greater use of ultrasonography and computed tomography (CT) in the emergency department could lead to preoperative diagnosis. The aim of this study was to describe the advisability of avoiding surgery in selected patients. PATIENTS AND METHOD: A series of nine adult patients (six men and three women), aged between 18 and 50 years, with a final diagnosis of primary omental torsion were reviewed. The first three patients underwent surgery: two underwent laparotomy for suspected acute appendicitis and the third underwent laparoscopy with a diagnosis of non-specific acute abdomen. The six remaining patients, who received a diagnosis of primary omental torsion or infarction based on ultrasonography and CT, underwent conservative treatment. The patients who did not undergo surgery were subsequently evaluated with imaging techniques to confirm resolution. RESULTS: In the first three patients, symptoms were resolved by resection of the affected omental section. In the six remaining patients, a 3-6 cm mass of soft tissue in the paraumbilical region, between the rectal sheath and the transverse colon, was found. The lesions were hyperechoic or of mixed attenuation. These findings, together with the absence of other radiological and clinical signs, led to the preoperative diagnosis. Treatment was conservative and a fast recovery, observed both clinically and radiologically, was made. CONCLUSIONS: Surgery should be avoided in selected cases of acute abdomen diagnosed as primary omental torsion.

[Mallory-Weiss syndrome as etiologic factor of upper gastrointestinal hemorrhage. A review of 142 cases]. / El síndrome de Mallory-Weiss como factor etiológico en la hemorragia digestiva alta. Revisión de 142 casos.

The diagnosis of Mallory-Weiss syndrome was made in 142 patients with upper gastrointestinal haemorrhage by early endoscopy. These patients represent 5.16% of all patients with haemorrhage treated in our unit over a period of ten years. Emergency surgery was needed in 13 due to persistent haemorrhage. In the remaining 129, conservative management sufficed to stop the bleeding. All patients receiving medical therapy survived while one of the surgically treated patients died of pulmonary thromboembolism in the early postoperative period.
