Outcomes of surgically managed recurrent parastomal hernia: the Sisyphean challenge of the hernia world

PURPOSE

The management of a recurrent (symptomatic) parastomal hernia (PSH) presents a dilemma. The aim of this study was to review the outcome of patients who underwent a recurrent PSH repair.

METHODS

Retrospective review of consecutive patients undergoing recurrent PSH repairs at a single institution between 2010 and 2019. Primary outcome recorded was recurrence. Secondary outcomes recorded were 30-day post-operative complications, surgical site occurrence (SSO) incidence and to assess if EHS classification altered with each recurrence.

RESULTS

Thirty-eight patients underwent 59 recurrent PSH repairs during the study period. Median number of PSH repairs per patient from ostomy formation was 2 (2-8). Post-operative complications occurred following 52.5% of repairs. Recurrence rate for all recurrent PSH hernia repairs was 45.7%, with a median follow-up of 58 months (0-115). A trend was seen towards a shorter PSH recurrence-free survival in those who had at least two previous PSH repairs at the start of the study period when compared to those who had less. Recurrence was not associated with operative urgency, type of repair, mesh type or SSO occurrence. A significant decrease in recurrence was seen with retro-rectus mesh placement when compared to onlay (p = 0.003). EHS classification did not change between each recurrence in 70.8% of patients.

CONCLUSION

Recurrence rates after recurrent PSH repair are high. The recurrence-free survival was worse after the second or more attempt at repair for recurrence. Further studies are warranted to explore prophylaxis, optimal repair method, and where re-recurrence occurs, the benefit of repeated surgical intervention.

Comments on Saint’s triad

Yamanaka et al. described two case studies involving coexistent cholelithiasis, hiatal hernia, and umbilical hernias, and discussed clinical similarities with the classical features of the Saint’s triad. Cholelithiasis, hiatal hernia, and colonic diverticulosis characterize the classical triad, but some authors have included any type of hernia due to herniosis—a developmental disorder of the extracellular matrix. The main features of this triad, which seem to be underdiagnosed and/or underreported, are discussed. Therefore, the commented manuscript contributed to better understanding the scarcely reported condition.

A rare case of interparietal incisional hernia from 8 mm trocar site after robot-assisted laparoscopic prostatectomy

Trocar site hernia arising from 8 mm robotic port is very rare despite the increasing prevalence of robot-assisted surgeries. To date, there had been only a single case reported in the literature. We report a case of small bowel obstruction secondary to an interparietal trocar site incisional hernia after robot-assisted laparoscopic prostatectomy. Meticulous closure of 8 mm robotic trocar sites associated with large peritoneal defect at the end of surgery should be performed.

The role of biologic meshes in abdominal wall reconstruction

There are unacceptably high rates of recurrence following surgery for incision hernia repair using suture repair techniques in isolation. As the reconstruction of abdominal walls has expanded with complex surgery, the materials used as adjuncts to support the repair have changed. In the article we review the current use of biologic meshes in abdominal wall reconstruction and the techniques used.
