LIFT procedure: postoperative outcomes, risk factors for fistula recurrence and continence impairment.

Ligation of the intersphincteric fistula tract has been recently employed as definitive treatment of anal fistulas. However, it carries a potential risk of continence impairment, fistula recurrence, and repeated operations. This study aimed to assess postoperative outcomes related to this procedure and evaluate the potential influence of preoperative and intraoperative features. Patients who underwent LIFT procedure between June 2012 and September 2021 were retrospectively analyzed. Patients were divided according to whether they developed fistula recurrence and on the history of a surgery prior to the LIFT. Preoperative features, postoperative outcomes, and risk factors adverse outcomes were analyzed. Forty-eight patients were included, of which 25 received primary LIFT, being the high transsphincteric fistula pattern the most frequent (62.5%). The median follow-up was 13.3 months, with a recurrence rate of 20.8%, of which the majority presented an intersphincteric fistula pattern (50%); and continence impairment rate of 16.7%. A higher prevalence of diabetes (p = 0.026) and a trend towards a higher prevalence of patients with a history of high transsphincteric fistula (0.052) were observed in the group with fistula recurrence. The history of diabetes and the operation time with a cut-off value ≥ 69 min showed a trend as a risk factors for developing fistula recurrence (0.06) and postoperative continence impairment (0.07), respectively. The LIFT procedure seems to be safe in terms of morbidity, with a reasonable incidence of recurrences, showing better results when it is primarily performed. Preoperative characteristics should be considered as they may impact outcomes.

Adult intussusception: still a challenging diagnosis for the surgeon.

INTRODUCTION AND AIM: Intussusception is rare in adults and can occur in the small bowel and colon. Its atypical presentation makes the diagnosis difficult. The aim of the present study was to evaluate the causes, clinical characteristics, and treatment outcomes of adult intussusception and to determine whether there was an association between etiology and clinical presentation. MATERIALS AND METHODS: A retrospective study was carried out on patients above 18 years of age that were treated for intussusception at a tertiary care hospital, between 2000 and 2020. The findings were summarized utilizing descriptive and inferential statistics. RESULTS: Twenty-eight cases were identified. Median patient age was 46 years (18-80) and median symptom duration was 18 days. Abdominal pain was the most frequent symptom (96.42%). The intussusceptions registered were enteroenteric (14), ileocecal (4), ileocolonic (4), colocolonic (5), and colorrectal (1). Intussusception etiology was benign in 15 cases, 9 were associated with malignancy, and 4 were idiopathic. Surgery was performed on 11 patients with enteroenteric intussusception and on all the cases of ileocecal, ileocolonic, colocolonic, and colorectal intussusception. There were 2 events of perioperative mortality (8%) and 8 of postoperative morbidity (32%). No significant differences were found regarding symptom duration or length of hospital stay, when the etiologic groups were compared. CONCLUSIONS: Intussusception is rare in adults. Diagnosis is a challenge because of the nonspecific signs and symptoms. Surgical resection should be considered in the definitive treatment and management should be individualized according to the patient's comorbidities, clinical presentation, and risk of malignancy.

Laparoscopic Roux-en-Y gastric bypass in the treatment of obesity: evidence based update through randomized clinical trials and meta-analyses.

Bariatric surgery was introduced in 1953, but during the last 20 years its popularity has increased after the development of significant Romaevidenced based breakthroughs in the field. Currently, approximately 150 long-term randomized clinical trials and 40 meta-analyses support and give credibility to the surgical approaches for the treatment of obesity and its related metabolic disturbances. Bariatric surgery has demonstrated improved outcomes compared to medical treatment, conduct therapy, and endoscopic procedures. Roux-en-Y gastrojejunostomy (RYGB) and Sleeve gastrectomy (SG) are the surgical procedures most frequently performed, due to their satisfactory results and security profile. There is sufficient evidence in medical literature to perform these procedures when indicated; however, there are still several controversies regarding technical aspects that need to be further explored.

Contrast-enhanced swallow study sensitivity for detecting esophagojejunostomy leakage. / Sensibilidad del trago de contraste hidrosoluble para la detección de fugas de anastomosis esofagoyeyunal.

INTRODUCTION AND AIM: Sixty percent of the patients with gastric carcinomas are candidates for surgical resection through total gastrectomy and esophagojejunostomy, the latter of which is associated with leaks in up to 12.3% of cases. There is no standardized procedure for diagnosing anastomotic leaks. The aim of the present study was to establish the diagnostic sensitivity of the contrast-enhanced swallow study for detecting esophagojejunostomy leakage after total gastrectomy. MATERIALS AND METHODS: A retrospective analysis was conducted on patients that underwent total gastrectomy due to gastric adenocarcinoma, within the time frame of 2002 and 2017. Demographic, clinical, and laboratory factors were identified, emphasizing the clinical and radiologic detection of anastomotic leaks. Descriptive statistics were carried out and the sensitivity of the contrast-enhanced swallow study for diagnosing leakage was calculated. RESULTS: Fifty-eight patients were included in the study. Their mean age was 61.5 years. A total of 55.2% of the patients were men and 44.8% were women. Gastric adenocarcinoma was the indication for gastrectomy in 100% of the cases. Anastomotic leak presented in 31.01% of the patients. Diagnostic sensitivity of the contrast-enhanced swallow study for detecting leaks was 66%. CONCLUSIONS: According to our analysis, the contrast-enhanced swallow study had limited diagnostic efficiency for detecting anastomotic leaks, with a sensitivity of 66%. We suggest maintaining high diagnostic suspicion in patients with studies that are initially negative and basing decisions on a more extensive approach.
