Abstract
BACKGROUND: Single-incision laparoscopic surgery (SILS), which has been demonstrated to be safely applied on kinds of surgeries, may represent an improvement over conventional multi-port laparoscopic surgery. However, there are still few clinical experiences of SILS in pancreatic surgery until now. In this study, we will summarize our experience of transumbilical single-incision laparoscopic distal pancreatectomy (TUSI-LDP), and compare its related parameters with conventional multi-port laparoscopic distal pancreatectomy (C-LDP). METHODS: A retrospective analysis was conducted for the patients who underwent C-LDP or TUSI-LDP in our department. The demographic data, operative parameters, and postoperative complications in the two groups were summarized and compared. RESULTS: Laparoscopic distal pancreatectomy was performed in a total of 21 cases, among which TUSI-LDP was performed in 14 cases. As far as the demographical results concerned, there were no significant differences between the two groups. The conversion to open surgery was conducted in one case in the TUSI-LDP group because of severe adhesion between pancreatic cyst and surrounding tissues, while in the C-LDP group the only one conversion was for the difficult detection of small lesion. The mean operating time and intraoperative blood loss in TUSI-LDP group was a little shorter (166.4 ± 57.4 versus 202.1 ± 122.5 minutes, p > 0.05, and 157.1 ± 162.4 versus 168.6 ± 157.4 ml, p > 0.05). The postoperative pain and post-operation lengths of hospital stay in the TUSI-LDP group were also less, though there was no significant statistical difference between the two groups. For the post-operation complications, in TUSI-LDP group the pancreatic leakage occurred in only one case, and ceased spontaneously with only a drain for 61 days. There were no other complications including postoperative hemorrhage, venous thrombosis, infections and so on in both groups. CONCLUSION: For the experienced laparoscopic surgeons, in selected patients, TUSI-LDP is a feasible technique, with excellent cosmetic effect, less postoperative pain and post-operation lengths of hospital stay. With the experience accumulated, the operating time and intraoperative blood loss of TUSI-LDP could also gradually reduce.
