Factors affecting recurrence after incisional hernia repair.

Incisional hernias occur primarily as a result of high tension and inadequate healing of a previous incision, the latter of which is frequently related to infection at the surgical site. Despite recent advances in operative techniques, the recurrence rate remains unacceptably high. To evaluate the impact of different predisposing factors for the recurrence of incisional hernia, we reviewed retrospectively the medical records of 297 patients who had undergone incisional herniorrhaphy (188 tissue repairs, 109 mesh repairs) in our hospital. Demographic data (age and gender), type of repair, body mass index, hernia size, presence of chronic illnesses and wound complications were evaluated in a univariate and multivariate manner analysis. The overall recurrence rate was 30.3%, with the recurrence rate in patients who underwent tissue repair being 39.4% and that in patients following prosthetic repair 14.6%. The recurrence rate was significantly influenced by type of repair, obesity, hernia size, wound healing disorders and some chronic comorbidities. We conclude that it is necessary to become familiar with the risk factors for recurrence of incisional hernia in order to eliminate or decrease their effect on the positive outcome of incisional herniorrhaphy.

Early results of recently introduced laparoscopic adjustable gastric banding procedure for morbid obesity in Croatia.

INTRODUCTION: Morbid obesity is a growing medical problem that has become of epidemic proportions. Various dietary and pharmaceutical approaches do not obtain acceptable long-term results. Surgery, however, especially gastric restriction, represents a viable therapeutic solution. Individuals with a body mass index (BMI) >40 kg/m2 or >35 kg/m2 with at least one severe comorbidity are considered morbidly obese and generally qualify for weightloss surgery. Laparoscopic adjustable gastric banding (LAGB) is currently the most commonly performed procedure, because it is minimally invasive, does not cause metabolic complications, is completely reversible, and is adjustable. In Croatia, the first LAGB was performed in May 2004 at Clinical Hospital "Sestre Milosrdnice." The aim of this report is to illustrate a newly performed surgical treatment and its results for morbid obesity in Croatia. METHODS: Within a 12-month period, the adjustable gastric band was implanted in 15 morbidly obese patients (female, 8; male, 7; mean age, 46.67 years; range, 26-59 years). The so-called "pars flaccida" technique was used. RESULTS: One operation required conversion to laparotomy due to a gastric lesion, and 1 laparoscopy operation was terminated due to massive postoperative adhesions. The average duration of surgery was 90+/-30 minutes. Mean length of stay was 4.9 days (range, 3-9). An average BMI at the time of surgery was 52.21 kg/m2 (range, 45.29 to 61.59; mean body weight was 155.58 kg (range, 127 to 204). Throughout 1-, 3-, 6-, 9-, and 12-month follow-ups, an average of 18.71%, 25.06%, 34.37%, 41.23%, and 47.32% of excessive weight loss (EWL) was observed. Good tolerance and a low complication rate were noted. CONCLUSION: LAGB resulted in good early results and a low complication rate. LAGB appears to be a quality surgical procedure for the management of morbid obesity.
