Prophylactic mesh does not prevent parastomal hernia in long-term: Meta-analysis and trial sequential analysis.

BACKGROUND: Previous randomized clinical trials, systematic reviews, and meta-analyses evaluating parastomal hernia prevention with mesh placement during end colostomy formation have reported contradictory results. This review aimed to assess the efficacy of this strategy in long-term follow-up according to the latest available data. METHODS: Medline, EMBASE, Cochrane Library, Web of Science, and Google Scholar were searched. Randomized clinical trials were included if they compared mesh with no mesh during initial end colostomy creation in adult patients to prevent parastomal hernia with a follow-up longer than 2 years. A meta-analysis was performed to evaluate parastomal hernia incidence (primary outcome), parastomal hernia repair rate, and mortality. Subgroup analysis included surgical approach and mesh position, and trial sequential analysis was performed. RESULTS: Eight randomized clinical trials involving 537 patients met the inclusion criteria. Based on long-term follow-up, the incidence of parastomal hernia was not reduced when a prophylactic mesh was placed (relative risk = 0.68 [95% confidence interval:0.46-1.02]; I2 = 81%, P =.06). The parastomal hernia repair rate was low; however, no difference was found between the groups (relative risk = 0.90 [95% confidence interval:0.51-1.56]; I2 = 0%; P = .70), and no difference was detected between the groups when mortality was assessed (relative risk = 1.03 [95% confidence interval: 0.77-1.39]; I2 = 21%; P = .83). Subgroup analyses did not show differences according to the surgical approach or mesh position used. Regarding trial sequential analysis, an optimal information size was not achieved. CONCLUSION: Prophylactic mesh placement during end colostomy formation does not prevent parastomal hernia in the long term. The parastomal hernia repair rate and mortality rate did not vary between the included groups. Heterogeneity among the included randomized clinical trials might restrict the reliability of the results.

Parestomal hernia repair. Prospective observational study based on the Spanish Registry of Incisional Hernia (EVEREG).

INTRODUCTION: The results of parastomal hernia (PH) repair based on data from registries are scarce. The objective of this work is to analyze the data collected on PH in the National Registry of Incisional Hernia (EVEREG) and thus evaluate current practices and results in PH repair. METHODS: Data from the PH cohort recorded in the period from July 2012 to June 2018 are analyzed. Complications, recurrences and associated factors of the entire PH cohort are analyzed, regardless of the type of stoma they are associated with. Subsequently, the same PH group analysis was performed in relation to a colostomy (larger group). RESULTS: 353 PH were studied. Of these, 259 (73%) were PH in the context of a terminal colostomy, 74 (21%) in the context of a terminal ileostomy, and 20 (6%) in the context of a ureteroileostomy (Bricker). The global mean age was 68.7 ± 11.1 years and 135 (38%) patients were female. The open approach and elective surgery were predominant (78% and 92% respectively); 99% were repaired with a non-absorbable synthetic mesh. Global postoperative complications were high (30.6%). As well as, the global recurrence (27.5%) after a mean follow-up of 9.4 months. CONCLUSIONS: PH repair is infrequent. PH surgery seems to be associated with a high percentage of postoperative complications and recurrence.

[Abdominal Wall Surgery After SARS-CoV-2: Time to Reestablish Postponed Non-essential Procedures?] / Cirugía de la pared abdominal después del SARS-CoV-2: ¿es hora de restablecer los procedimientos no esenciales pospuestos?

Pandemic by the COVID-19 has found us unprotected to provide an adequate and rapid sanitary response. The hospital network of our public health system has provided most of the resources for the treatment of patients affected by the infection. Non-essential (non-priority) surgeries have been postponed. The optimal and proportionate reestablishment of these non-priority surgeries can be a problem. This article offers a technical and non-technical view of reestablishment non-priority surgeries from the perspective of abdominal wall surgery.
