Intraperitoneal onlay mesh repair (IPOM) plus technique using a hybrid procedure of open laparotomy and laparoscopic approach (hybrid IPOM plus) for incarceration of umbilical hernia in a severely obese patient: a case report

BACKGROUND: A standard procedure for the treatment of incarcerated umbilical hernia among severely obese patients has yet to be established. We used the hybrid intraperitoneal onlay mesh repair (IPOM) plus method, which combines open and laparoscopic surgery to treat incarcerated umbilical hernia in a severely obese patient. CASE PRESENTATION: A 46-year-old man presented in our department with a chief complaint of a painful mass in the umbilical region. Incarcerated umbilical hernia was diagnosed on the basis of abdominal computed tomography, and the decision was made to perform emergency surgery. The patient was severely obese (body mass index, 53.8 kg/m(2)), and the incarcerated portion of the hernia was therefore first addressed by open surgery. As bowel resection was unnecessary, the risk of infection was considered low, and after direct closure of the hernia orifice, IPOM was performed laparoscopically using the hybrid IPOM plus method. CONCLUSION: Among severely obese patients, first trocar insertion is difficult and the wound site tends to come under strain, meaning that simple closure of the hernia orifice results in a high recurrence rate. The hybrid IPOM plus method used in this case combines open surgery and laparoscopy and appears useful for treating uninfected incarcerated umbilical hernia in severely obese patients safely and with an anticipated low rate of postoperative recurrence.
