Multiparametric evaluation of risk factors associated to seroma formation in abdominal wall surgery

Do drain tubes help reduce risks of post-operative complications in complex incisional hernia repair (as defined by a recent court ruling)?

BACKGROUND

A recent legal case described in the ANZ Journal of Surgery has sparked significant topical interest in drain tube use in incisional hernia repairs in Australia. This study reviews a single centre experience of drain tube use in incisional hernia repair.

METHODS

Data from online clinical records was collected retrospectively from patients that underwent incisional hernia repair from 1 January 2013 to 31 December 2017. 'Complexity' factors of smoking, obesity and lower midline incision (as identified by the legal case) were also used to stratify groups.

RESULTS

A total of 410 incisional hernia repair cases were identified during the 5-year period. Median length of stay of the non-drain placement group was significantly shorter than that of the drain placement group (2 versus 6 days, P < 0.001). In total, 10.8% of patients with drain suffered from post-op wound infection compared to 3.6% in patients without a drain tube in-situ (P = 0.005). Seroma rates were no different with or without a drain (15.7% versus 16.9% P = 0.78). When stratified by 'complexity', there was a trend towards increased complications when drains were used.

CONCLUSION

Drain tubes were placed in only a small proportion of patients during incisional hernia repairs and were associated with a higher post-operative wound infection rate. When stratified by the 'complexity' factors outlined by the recent legal case, complications in more 'complex' patients may actually increase when a drain tube is used.

The abdominal wall incisional hernia repair in cirrhotic patients

BACKGROUND

The incidence of abdominal wall hernia in cirrhotic patients with ascites is between 20 and 40%. Controversies regarding the treatment modality and surgical timing of abdominal wall incisional hernia repair in cirrhotic patients remain. The study proposed wants to analyze the abdominal incisional hernia repair in cirrhotic patients with ascites performed in a single center to determine post-operative morbidity, mortality and complication rate.

PATIENTS AND METHODS

Cirrhotic patients with abdominal incisional hernia that underwent surgical operation for abdominal wall hernia repair at the "Policlinico Paolo Giaccone" at Palermo University Hospital between January 2015 and December 2016 were identified and the data collected were retrospectively reviewed; patients' medical and surgical records were collected from charts and the surgical and ICU registries. The degree of hepatic dysfunction was classified using Child-Pugh classification. Post-operative mortality was considered up to 30-days after surgery. A follow-up period of 6 months at least was performed to evaluate hernia recurrence and complications.

RESULTS

Mortality rate is of 18.5% (p 0.002). Recurrence rate (p 0.004) and seroma formation rate (p 0.001) are most frequent in urgency group. The elevated ASA score and the prediction of a complicated post-operative course is higher in urgency group (p 0.004) as higher is the in-hospital stay (p 0.001) and the ICU stay (p 0.001).

CONCLUSIONS

Elective surgery for abdominal wall hernia repair in cirrhotic patients seems to be successful and associated with lower mortality/morbidity rate and recurrence rate than urgency.
