Objective: To evaluate the wound complication rate in patients undergoing transumbilical single port laparoscopic cholecystectomy (SP-C).
Background: SP-C is said to be less invasive than conventional laparoscopic cholecystectomy. However, SP-C is performed less commonly compared to conventional laparoscopic cholecystectomy. One of the reasons for this is concern over wound complications including the umbilical hernia after SP-C. A higher wound complication rate related to transumbilical incision has been reported in some studies.
Methods: 463 consecutive SP-C were performed by a single surgeon between May, 2009 and February, 2017. Two cases of conversion from SP-C to open surgery were excluded. All procedures were followed postoperatively for a minimum of 6 months, and wound complications such as bleeding, fat lysis, infection, or hernia were recorded. Patients were classified as having a wound complication or not.
Results: Pure transumbilical SP-C was completed 94.6%, additional trocars were used in 5.0%, and the rate of conversion to open surgery was 0.4%. After a median follow-up of 32.1 (range, 6-50) months, 14 wound complications (3.0%) had occurred (bleeding 0%/ fat lysis 2.0%/ infection 0.7%/ hernia 0.4%, respectively). Factors associated with wound complications were higher body mass index and longer skin incisions. Furthermore, a learning curve effect was noted after 200 procedures.
Conclusions: The incidence of would complications is acceptably low with SP-C.
