title: Transumbilical single-incision laparoscopic cholecystectomy: long-term review from a single center.
abstract: Currently, researches about single-incision laparoscopic cholecystectomy (SILC) are various, but long-term reviews assessing relevant complications after SILC with considerable amount of case series are rare.
  
  
  
  We retrospectively reviewed a large series of 529 patients undergoing SILC to assess the long-term postoperative recovery, including postoperative complications, retained symptoms, and quality of life. Finally, we assessed its associated risk factors related to SILC patients' recovery in the long term.
  
  
  
  During a mean follow-up period of 36.8 ± 8.8 months after SILC, 402 (76.0 %) patients underwent complete resolution. Frequent diarrhea (12.1 %) and recurrent omphalitis (5.9 %) were most commonly seen among other complications and retained symptoms within overall the patients. We identified 1 (0.3 %) incision hernia and 1 (0.3 %) intra-abdominal abscess among overall the patients, while 3 (0.8 %) common bile duct stones and 1 (0.3 %) biliary pancreatitis among the patients with symptomatic cholelithiasis during long-term review period. No significant differences were identified between patients with symptomatic cholelithiasis and gallbladder polyps when considering other incidences (all p > 0.05). Patients undergoing SILC with older age (p = 0.023) or female gender (p = 0.020) contributed to complete resolution.
  
  
  
  SILC via traditional devices is feasible and safe with acceptable postoperative incidence rate in the long run. Patients with older age or female gender, who have no severe systemic diseases, tend to benefit more from the surgical intervention.
