Wound complications in 463 consecutive transumbilical single port laparoscopic cholecystectomy

Noriaki Kameyama, PhD, Ryo Nishiyama, PhD, Yuki Seo, PhD, Tomoko Takesue, PhD, Shodai Mizuno, MD, Yoshinobu Akiyama. KKR Tachikawa Hospital

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.
