For benign gynecological diseases, laparoscopic surgery has become a standard method. Its advantages include fast recovery, shorter hospital stay, decreased analgesic requirements, and lower perioperative complications. In recent years, laparoendoscopic single-site (LESS) surgery has become a new branch of surgery that increases cosmetic benefits over traditional endoscopic surgery . Recent reports suggest that LESS surgery has an advantage over conventional laparoscopic surgery in the aspect of postoperative pain and the use of analgesia [2–6].
Here, we present the first case of ovarian tumor treated by LESS surgery, which has been successfully applied in a patient complicated with paraumbilical hernia, using its hernia ring as a placement site for the single port.
Minimally invasive surgery has become a standard of care for the treatment of many benign gynecological diseases. From the fact that each working port carries with it an inherent risk of bleeding, infection, concordant organ damage, and hernia formation and that it decreases cosmetics, the natural goal in minimally invasive surgery is to reduce the number of ports to perform the procedure . LESS surgery is an advancing technique, which involves performing laparoscopic surgery through a single, small-skin incision concealed within the umbilicus. Reports of LESS surgery from general surgery and urology have indicated that LESS surgery not only improved cosmetics, but also, in many cases, it resulted in a shorter hospitalized period and decreased postoperative analgesia requirements when compared with conventional laparoscopic approaches. Recently published data suggest feasibility, safety, and reproducibility for LESS surgery in gynecology . There are reports suggesting that patients who undergo LESS surgery have less postoperative pain compared with those who received conventional laparoscopic surgery. An RCT trial was reported that LESS surgery provides an advantage over conventional laparoscopic approaches in terms of postoperative pain and need for rescue analgesia for benign adnexal diseases [2, 3].
We present the first case of the accomplishment of LESS surgery being applied to an obese patient with an ovarian tumor and paraumbilical hernia using the ring of the hernia as a placement site for the single port. To our knowledge, there is only one case report that underwent single-port cholecystectomy through the lateral ring of the left inguinal hernia . There have been no reports using the current procedure for the treatment of ovarian tumor. By inserting the single port into the hernia ring, extra incision of the abdominal wall can be avoided, making the operation less invasive. Abdominal wall hernias are quite common. There are reports that the incidence of abdominal hernia is 1.5 to 2.0 % . Therefore, we would like to emphasize that LESS surgery is feasible, using the abdominal wall defect as a place to insert the single port.
In our case report, the patient’s BMI was 31.6 kg/m2. A BMI under 25 kg/m2 is normal, a BMI between 25 and 29.9 kg/m2 is considered overweight, and a BMI of 30 kg/m2 or more is defined as obesity . Obesity results in a greater postoperative risk of atelectasis, pneumonia, deep venous thrombosis, pulmonary embolus, ileus, and wound infection . There are reports that obese patients are associated with prolonged first flatus, later commencement of soft diet, increased administration of analgesics, and prolonged hospital stay . Obesity was initially considered as a relative contraindication to operative laparoscopy. However, a growing body of evidence advocates the feasibility and safety of laparoscopic techniques rather than open surgery in obese individuals. Laparoscopy is currently considered to be a suitable technique for obese patients because it is minimally invasive, results in less postoperative pain, limits the risk of surgical site infection, leads to fewer postoperative ileus, and leads to rapid recovery and shorter period of hospitalization than open procedures . Minimally invasive LESS surgery may be the best indication for obese patients if technically possible because it can further reduce the risk of postoperative wound infection by eliminating the number of trocar sites. Also, less postoperative pain may enable obese patients to resume normal activities more quickly and limit the risk of thromboembolic events and faster return of bowel functions . From this point of view, we consider that LESS surgery may be a better minimally invasive approach especially to obese patients. We hope that more research data will be accumulated on this field of laparoscopy and obesity.
In conclusion, we demonstrate the first case of an obese patient with a paraumbilical hernia being treated to cure an ovarian tumor by laparoendoscopic single-site surgery using the ring of the hernia to place the single port. In this case report, we wish to highlight that when laparoscopic operation is considered in patients complicated with abdominal wall defect, LESS surgery using the hernia ring to place the single port can be considered a feasible and safe surgical approach.
