Severe dysphagia after antireflux surgery: a rare case of esophageal hiatal stenosis.

Severe and persistent dysphagia (PD) due to a stenosis of the esophageal hiatus is a serious and rare complication after antireflux procedures. In the case report presented here, the treatment of dysphagia, which arose eight weeks after surgery and progressively worsened, required a new laparoscopic approach. The re-intervention undertaken allowed us to identify the cause of the dysphagia, a tight hiatal stenosis, and to treat it successfully.

Complete Fundus Mobilization Reduces Dysphagia After Nissen Procedure.

Background. Anti-reflux surgery is an effective treatment for gastroesophageal reflux disease (GERD). Nevertheless, surgery is still indicated with great caution in relation to the risk of complications, and in particular to postoperative dysphagia (PD). Objective. To compare the clinical outcomes, with particular focus on the incidence and severity of PD, of laparoscopic Nissen-Rossetti fundoplication (NRF) and floppy Nissen fundoplication (FNF) with complete fundus mobilization, in the surgical treatment of GERD. Methods. Ninety patients with GERD were enrolled. Forty-four patients (21[47.7%] men, 23[52.2%] women; mean age 42.4 ± 14.3 years) underwent NRF (Group A), and 46 patients (23[50%] men, 23[50%] women; mean age 43.3 ± 15.4 years) received laparoscopic FNF with complete fundus mobilization (Group B). Clinical assessment was performed using a structured questionnaire and SF-36 quality of life (QoL) score. PD was assessed using a validated classification, and an overall outcome was also determined by asking the patient to score it. Results. At 24-month follow-up, 38 (88.3%) patients in Group A vs 39 (86.6%) in Group B reported to be completely satisfied with reflux relief and free of protonic pump inhibitors (PPIs), while 3 (6.9%) in Group A vs 2(4.4%) in Group B reported occasional PPI intake and 2(4.6%) in Group A vs 4(8.8%) in Group B needed regular PPI use. Persistent PD was observed in 8(18.6%) patients in Group A and in 2(4.4%) in Group B (P = .03). No significant differences were found in the QoL score and in the overall outcome perceived by the patients. Conclusion. FNF, with complete fundus mobilization, appears to be associated with a lower rate of postoperative persistent dysphagia.

Role of colonoscopy in the diagnostic work-up of bowel endometriosis.

AIM: To evaluate the accuracy of colonoscopy for the prediction of intestinal involvement in deep pelvic endometriosis. METHODS: This prospective observational study was performed between September 2011 and July 2014. Only women with both a clinical and imaging diagnosis of deep pelvic endometriosis were included. The study was approved by the local ethics committee and written informed consent was obtained in all cases. Both colonoscopy and laparoscopy were performed by expert surgeons with a high level of expertise with these techniques. Laparoscopy was performed within 4 wk of colonoscopic examination. All hypothetical colonoscopy findings (eccentric wall thickening with or without surface nodularities and polypoid lesions with or without surface nodularities of endometriosis) were compared with laparoscopic and histological findings. We calculated the sensitivity, specificity, positive predictive value and negative predictive value for the presence of colonoscopic findings of intestinal endometriosis. RESULTS: A total of 174 consecutive women aged between 21-42 years with a diagnosis of deep pelvic endometriosis who underwent colonoscopy and surgical intervention were included in our analysis. In 76 of the women (43.6%), intestinal endometrial implants were found at surgery and histopathological examination. Specifically, 38 of the 76 lesions (50%) were characterized by the presence of serosal bowel nodules; 28 of the 76 lesions (36.8%) reached the muscularis layer; 8 of the 76 lesions (10.5%) reached the submucosa; and 2 of the 76 lesions (2.6%) reached the mucosa. Colonoscopic findings suggestive of intestinal endometriosis were detected in 7 of the 174 (4%) examinations. Colonoscopy failed to diagnose intestinal endometriosis in 70 of the 76 women (92.1%). A colonoscopic diagnosis of endometriosis was obtained in all cases of mucosal involvement, in 3 of 8 cases (37.5%) of submucosal involvement, in no cases of muscularis layer involvement and in 1 of 38 cases (2.6%) of serosa involvement. The sensitivity, specificity, positive predictive and negative predictive values of colonoscopy for the diagnosis of intestinal endometriosis were 7%, 98%, 85% and 58%, respectively. CONCLUSION: Being an invasive procedure, colonoscopy should not be routinely performed in the diagnostic work-up of bowel endometriosis.
