ABSTRACT
BACKGROUND: A mesh-related intestinal fistula is an uncommon and challenging complication of ventral hernia repair. Optimal management is unclear owing to lack of prospective or long-term data. METHODS: We reviewed our prospective data for mesh-related intestinal fistulas from 2004 to 2017and compared suture repair versus ventral hernia repair with mesh at the time of mesh-related intestinal fistula takedown. RESULTS: Eighty-two mesh-related intestinal fistulas were treated; none of the fistulas had closed spontaneously, and all fistula persisted at the time of our treatment. Mean age was 61 ± 12 years with 33-month follow-up. Comorbidities were similar between groups. Defects were 2.5-times larger in ventral hernia repair with mesh (324 ± 392 cm2 vs 1301 ± 133 cm2; P = .044). Components separation (64% vs 21%; P = .0003) and panniculectomy (35% vs 7%; P = .0074) were more common in ventral hernia repair with mesh. Mortality occurred in 4 patients. Complications were similar. In patients undergoing ventral hernia repair with non-bridged, acellular, porcine dermal matrix, hernia recurrence was less than in patients without mesh (26% vs 66%; P = .0030). Only partial excision of the mesh involved with the fistula resulted in a substantial increase in developing another fistula (29% vs 6%; P < .05). CONCLUSION: Patients undergoing preperitoneal ventral hernia repair with mesh for mesh-related intestinal fistula had a lesser rate of hernia recurrence and similar complications compared to suture repair despite larger hernias. Complete mesh excision decreases the risk of fistula recurrence. We maintain that ventral hernia repair with mesh during mesh-related intestinal fistula takedown represents the best opportunity for a durable herniorrhaphy.

The incidence and causes of failed paraesophageal hernia repairs (PEHR) remain poorly understood. Our study aimed to evaluate long-term clinical outcomes after reoperative fundoplication as compared with initial PEHR. A prospectively maintained institutional hernia-specific database was queried for PEHR between 2008 and 2017. Patients with prior history of PEHR were categorized as "redo" paraesophageal hernia (RPEH). Primary outcomes included postoperative morbidity, mortality, symptom resolution, and hernia recurrence. A total of 402 patients underwent minimally invasive PEHR (Initial PEH = 305, RPEH = 97). Redo PEHR had more prevalent preoperative nausea/vomiting (50.6% vs 34.1%, P < 0.007) and weight loss (24.1% vs 13.5%, P < 0.02). RPEH had had longer mean operative time (256.4 ± 91.2 vs 190.3 ± 59.9 minutes, P < 0.0001) and higher rate of conversion to open (10.3% vs 0.67%, P < 0.0001); however, no difference was noted in postoperative complications, hernia recurrence, or mortality between cohorts. Laparoscopic revision of prior PEHR in symptomatic patients can be safely performed with favorable outcomes compared with initial PEHR. Despite redo procedures seeming to be more technically demanding (as noted by longer operative time and higher conversion rates), outcomes are similar and overall resolution of symptoms is achieved in most patients.
