ObjectiveTo compare the advantages and disadvantages of transumbilical single port (TUSP) and conventional laparoscopic cholecystectomy (LC). MethodsThe clinical data of 45 patients underwent elective LC were analyzed, 20 patients with TUSP LC (TUSP-LC group), 25 patients with conventional LC (conventional LC group). The operation time, Child-Pugh score and painkiller application frequency within three days after operation, the first time of out of bed and hospital stay after operation, intraoperative blood loss, chronic pain within one month after surgery were compared between two groups. ResultsAll cases were operated successfully except one patient in the conventional LC group. The frequency of painkiller application within three days after operation and postoperative hospital stay in the TUSP-LC group were better than those in the conventional LC group (Plt;0.05). There were no significant differences on postoperative chronic pain of surgical area within 1 month and Child-Pugh score between two groups (Pgt;0.05). The operation time and intraoperative blood loss in the conventional LC group were less than those in the TUSP-LC group (Plt;0.05, Plt;0.01). ConclusionTUSP LC has the advantages of small wound, slight pain, and fast recovery.
Objective To investigate the method of single umbilical port laparoscopic cholecystectomy and its feasibility. Methods The clinical data of 46 patients receiving single port umbilical laparoscopic cholecystectomy in this hospital from December 2008 to February 2009 were analyzed retrospectively. Results Fourty-six cases were operated successfully with ordinary laparoscopic instruments by single umbilical port laparoscopic cholecystectomy, all without drainage placed. Operative time was from 40 to 130 min, average 52.3 min; bleeding was from 10 to 150 ml, average 40.6 ml. No complications, such as biliary leakage, hemorrhage, umbilical hernia and infection of incisional wound happened. Postoperative abdominal wall scar was not obvious, 1-4 d hospitalization, from 2 weeks to 3 months following-up without disconnecting of incision. Conclusions The single umbilical port laparoscopic cholecystectomy is safe and feasible, with little abdominal wall scar, but difficult to perform, so it can be applied in hospitals with related conditions as improvements of laparoscopic cholecystectomy.
ObjectiveTo investigate the feasibility and clinical effect of controlled hypotension in 3 cm single-port video-assisted thoracoscopic surgery (VATS) for the lymph node group 7 dissection in the left lung resection. MethodsWe retrospectively analyzed the clinical data of 37 patients with lung cancer who underwent 3 cm single-port VATS from May 2015 to August 2015 in Tongji Hospital, and systolic blood pressure of 12 patients (7 males, 5 females, average age of 58.3 years, range 42-69 years) was controlled between 80-90 mm Hg by nitroglycerin or sodium nitroprusside while the pressure of 25 patients (14 males, 11 females, average age of 57.7 years, range 43-68 years) was not controlled when receiving lymph node group 7 dissection. ResultsControlled hypotension in lymphadenectomy achieved satisfactory results. The lymphadenectomy time of 12 patients with controlled hypotension (18.5±4.3 min on average, range 15.6-25.3 min) was shorter than that of 25 patients without controlled hypotension (24.3±5.1 min on average, range 18.2-29.8 min); the difference was statistically significant (P<0.05). ConclusionControlled hypotension is a simple and feasible method that increases the operating space, and reduces the difficulty of cleaning lymph nodes and the risk of bleeding.
