Transumbilical single-port laparoscopic cholecystectomy for chronic cholecystitis with cholecystolithi-asis / 中华肝胆外科杂志

Objective To study the feasibility, safety and aesthetics of laparoscopic cholecystectomy using a single-port through the umbilicus in patients with chronic cholecystitis with cholecystolithiasis. Methods From Jan 2007 to Jun 2017, the clinical data of 4790 patients who underwent single-port, 4426 patients conventional three-ports, and 3304 patients two-ports laparoscopic cholecystectomy were retrospec-tively studied. Results There were no death in all the three groups. There were no significant differences in the incidences of postoperative bleeding, bile leakage, biliary tract injury and other significant short-term complications (all P>0. 05). The operation time of transumbilical single-port laparoscopic cholecystectomy was significantly longer than that of two-ports and three-ports laparoscopic cholecystectomy [(35. 3 ± 9. 0) min vs. (28. 4 ± 7. 2)min vs. (23. 3 ± 6. 4)min, P<0. 05]. Looking only in a single year, there was no significant difference in the operation time of the three groups in the year 2017 (P>0. 05). There were no significant differences among the three groups in intraoperative blood loss, first postoperative passing of flatus, postoperative pain, and length of hospital stay (all P>0. 05). The satisfaction score of surgical scar in the single-port group was higher than that in the two-ports and three-ports groups [ ( 9. 6 ± 1. 6 ) vs. (7. 6 ± 1. 9) vs. (6. 7 ± 2. 0), P < 0. 05]. Conclusions Transumbilical single-port laparoscopic cholecystectomy was safe and feasible, with good aesthetics and other advantages. It was more difficult than the traditional laparoscopic technique. After the learning curve, the operation time could be comparable to the three-ports technique.

The experience of transumbilical endoscopic appendectomies

Minimally invasive surgery is being widely accepted in various fields of surgery. Although several appendectomy techniques have been reported but, there is no standardization. We report here the experiences of transumbilical endoscopic appendectomy in humans. Between July 2008 and September 2010, ten patients with appendicitis successfully underwent transumbilical endoscopic appendectomies. There were 7 cases of suppurative, 2 cases of gangrenous and 1 case of perforated in operative findings. The ages of the patients were 13-56 years (mean age, 32.7 +/- 15.4 years). Under general anesthesia, a 15-mm port was inserted through the umbilicus and then a two-channel endoscope was inserted in the peritoneal cavity. After appendix identification, counter-traction of the appendix with a direct abdominal wall puncture using a straight round needle prolene was performed to achieve good visualization of the operative field. Tissue dissection was performed using an endoscopic needle knife. Tissue grasping and resected appendix retrieval were done with endoscopic forceps. The average operation time was 79.5 +/- 23.6 minutes (range, 45 to 110 minutes). No procedures were converted to laparoscopic or open appendectomy. Hospital stay was 4-6 days. All patients completely recovered without complications. As it is highly maneuverable, we believe transumbilical endoscopic appendectomy can be a feasible method. And, as surgeons want to proceed from laparoscopic surgery to natural orifice transluminal endoscopic surgery, this procedure could be a triable method.

Comparison of laparoscopic transumbilical single-port appendectomy with conventional instrumentation versus three-port appendectomy / 中华全科医师杂志

Between May 2009 and February 2012,60 patients scheduled for laparoscopic appendectomy were randomly assigned to receive either transumbilical single-port laparoscopic appendectomy (TUSPLA) or three-port laparoscopic appendectomy (TPLA).The operative duration was significantly longer in TUSPLA than TPLA cases.No statistically significant differences existed in hospital stay,visual analog scale (VAS) score,analgesia requirement or complication rate.The abdominal scar was inconspicuous for TUSPLA.It suggested that TUSPLA with conventional instrumentation is technically feasible and safe with scarless healing.

Comparison of embryonic nature orifice transumbilical endoscopic surgery with conventional laparoscopic surgery treatmenting Hirschsprung disease / 中华实用儿科临床杂志

Objective To compare the therapeutic effects of embryonic nature orifice transumbilical endoscopic surgery(ENOTES) with conventional laparoscopic(CL) surgery in Hirschsprung disease(HD).Methods A total of 111 children from Sep.2009 to Dec.2010 were included in the retrospective study.The patients were divided into 2groups:ENOTES group (66 cases) and CL group (45 cases).The general conditions of children were reviewed operative situation,postoperative complications and defecation 1 year after operation.Results In the left colectomy,there was no difference between 2 groups in age,weight,operative blood loss and postoperative stay (all P ＞ 0.05),but ENOTES took up less time than CL(P ＜ 0.05) ;in the subtotal colectomy,no significant difference existed in all series.All children underwent primary radical surgery,neither transfer to open surgery nor dead case.In ENOTES group,there were 9 cases suffering from enterocolitis postoperatively (13.6％),while 7 cases (15.6％) in CL group.Twenty-eight patients in ENOTES group and 12 in CL group were followed up for 1 year.Less abdominal distension postoperatively was noted in ENTOES group than CL group(P ＜ 0.05),but no other difference in other available data.In addition,no obvious operative scar was noted on the abdomen in ENOTES group,what meant better cosmetic benefit than CL.Conclusion HD treated with ENOTES can gain the same outcomes with CL with better cosmetic effect.

Gastrectomía en manga transumbilical con técnica simplificada: técnica y resultados quirúrgicos en 100 pacientes / Simplifi ed transumbilical sleeve gastrectomy: technique and surgical results in 100 patients

Background: The use of transumbilical approach for sleeve gastrectomy has been recently reported, using different technique variations. Aim: To report the technique and surgical results of a transumbilical approach simplified sleeve gastrectomy, using rigid instruments. Material and Methods: Ninety four women and six men, selected by a multidisciplinary team, underwent transumbilical sleeve gastrectomy. The operative technique involved a transumbilical incision, introduction of a SILS® or GelPoint® multiport, and a 5mm metallic accessory trocar laterally in the left flank. Rigid instruments were used in all patients. The greater curvature was dissected from 4-5 cm above the pylorus to the angle of His. Gastric transection was completed with a stapler, and calibrated with a 36 French tube advanced through the pylorus. Hemostasis of the staple line was carried out with metallic clips. A barium swallow was performed in ten randomly chosen patients, confirming the correct tubular shape of the stomach. Results: Body mass index of operated patients ranged from 30 to 43 kg/m². Mean operative time was 56.4 +/- 16.7 minutes. During the early postoperative period, two patients had a hemoperitoneum, one had an antral leak and one had an intestinal perforation. No conversion to conventional laparoscopy or open technique was required. No patient died. The mean length of hospital stay was 2.3 +/- 0.5 days. The cosmetic result was satisfactory for all patients. Conclusions: Transumbilical sleeve gastrectomy is a safe and feasible procedure with the reported technique. The insertion of an accessory 5mm trocar in the left flank simplifies the procedure, allowing the use of rigid instruments.
