The aim of this study was to assess the surgical and oncological outcome for the management of endometrial cancer (EC) by laparoendoscopic single-site surgery (LESS).

We performed a retrospective chart review of patients who underwent a LESS for EC. All the patients were treated by the same surgical team between July 2009 and June 2013 at the Gynaecologic Oncologic Unit, Regina Elena National Cancer Institute, Rome, Italy.

A total of 50 women were included, with a median age of 45 years (range, 39-84 years) and a median body mass index (BMI) of 21.8 kg/m² (range, 19-48 kg/m²). Median operative time was 100 min (range, 50-240 min), median blood loss was 90 mL (range, 10-300 mL) and median hospital stay was 3 days (range, 2-9 days). The median number of pelvic lymph nodes retrieved was 14 (range, 5-20). No intraoperative complications occurred, but there were 4 postoperative complications. Two patients required a laparoscopic conversion. The median follow-up was 36 months (range, 16-62 months) and no recurrence occurred.

Our report showed that the LESS approach in the treatment of early EC can be a safe and reliable technique in terms of surgical and oncological outcomes.

AIM: To assess the safety of single-incision laparoscopic cholecystectomy (SILC) for acute cholecystitis.

METHODS: All patients who underwent SILC at Sano Hospital (Kobe, Japan) between January 2010 and December 2014 were included in this retrospective study. Clinical data related to patient characteristics and surgical outcomes were collected from medical records. The parameters for assessing the safety of the procedure included operative time, volume of blood loss, achievement of the critical view of safety, use of additional trocars, conversion to laparotomy, intraoperative and postoperative complications, and duration of postoperative hospital stay. Patient backgrounds were statistically compared between those with and without conversion to laparotomy.

RESULTS: A total of 100 patients underwent SILC for acute cholecystitis during the period. Preoperative endoscopic treatment was performed for suspected choledocholithiasis in 41 patients (41%). The mean time from onset of acute cholecystitis was 7.7 d. According to the Updated Tokyo Guidelines (TG13) for the severity of cholecystitis, 86 and 14 patients had grade I and grade II acute cholecystitis, respectively. The mean operative time was 87.4 min. The mean estimated blood loss was 80.6 mL. The critical view of safety was obtained in 89 patients (89%). Conversion laparotomy was performed in 12 patients (12%). Postoperative complications of Clavien-Dindo grade III or greater were observed in 4 patients (4%). The mean duration of postoperative hospital stay was 5.7 d. Patients converted from SILC to laparotomy tended to have higher days after onset.

CONCLUSION: SILC is feasible for acute cholecystitis; in addition, early surgical intervention may reduce the risk of laparotomy conversion.

Single-incision laparoscopic cholecystectomy (SILC) is a newly developed method of performing cholecystectomy and has been increasingly used. The aim of this study is to see if SILC has any advantages over conventional (three-port) laparoscopic cholecystectomy (CLC).

In this cross-sectional study, 52 patients who underwent SILC (group A) during the period from May 2011 to March 2013 were compared with 62 patients who underwent CLC (group B) at two centers affiliated to Shiraz University of Medical Sciences in Shiraz, Iran. Data were gathered on operation time, pre- and postoperative complications, patients’ postoperative pain, pain reliever use, duration of hospital stay, and return to work, and these data were compared using SPSS software version 16.

The mean age of patients was 38.01 ± 13.24 in group A and 44.82 ± 15.11 in group B. Mean body mass index (BMI) was 23.97 ± 4.78 and 26.22 ± 4.67 in groups A and B, respectively. The mean operation time was 76.4 ± 29.0 min in group A and 72.9 ± 24.1 min in group B (P = 0.496). Preoperative complications were 3.8% in group A and 0 in group B (P = 0.206). Postoperative complications were 17.3% in group A and 11.3% in group B (P = 0.423). The mean for early postoperative pain revealed no significant difference (P = 0.814), but the mean pain on discharge was significantly higher in group A patients (P = 0.034). Regarding the mean admission time and return to normal activity, we found no significant differences.

SILC does not have any special advantages over CLC with regard to surgical outcomes, but it can be a safe alternative to CLC, especially in patients concerned about cosmoses.

Surgery without scars is the dream of many patients and surgeons as well. It includes many new laparoscopic techniques (LESS, SILS, hybrid NOTES), but data concerning common bile duct (CBD) lesions are unavailable.

To establish the new technique of minilaparoscopic cholecystectomy (MCh): non-visible scar intervention without increasing the risk of CBD lesions.

Forty consecutive patients with symptomatic gallbladder lithiasis were qualified for elective laparoscopic cholecystectomy (LCh) using one 10/11 mm umbilical port, one 5 mm right suprapubic port and two minilaparoscopic, disposable, no-port graspers. There were 26 women and 14 men, with the mean age 56 (17–72) years and with the average body mass index 28 (18–33) kg/m². CO₂ Veress 15 mm Hg pneumoperitoneum was performed after transumbilical incision, and the first 10/11 mm port was inserted at the beginning for the 5 mm laparoscope and finally for typical instruments. Next under camera control, a 5 mm trocar was inserted in the right ‘bikini line’. To this port the laparoscope was relocated from the umbilicus, and under its control two minilaparoscopic, disposable, non-port graspers were introduced after small, 2 mm skin incisions in the right anterior axillary line and in the right mesogastrium to catch the gallbladder. Next through the umbilical port, using typical instruments, the cystic duct and artery were dissected, clipped and cut. The gallbladder was removed through the umbilical port whole.

There was no conversion to open cholecystectomy. In 5 cases drainage of the gallbladder lodge was necessary through a 5 mm port in the right bikini line. The time of the intervention ranged from 90 min during the introduction of the new method to 50 min for the last procedures. No postoperative complications were observed, and all patients were discharged at the same time as after conventional LCh.

Two-port laparoscopic cholecystectomy performed with two minilaparoscopic no-port graspers does not increase the risk of CBD lesions. It provides an excellent cosmetic effect and is very convenient for the surgeon like typical LCh.

SILC in the third world.

Scarless/single-incision laparoscopic cholecystectomy (SILC) is a new procedure. It affords a superior cosmetic outcome when compared to conventional laparoscopic cholecystectomy. We examine the application of this technique using LigaSure via a clipless method. The present study looks at the experience of a single surgeon using this method with initial evaluation of the safety, feasibility, affordability, and benefits of this procedure.

Twenty-eight patients underwent transumbilical SILC at Doctors Hospital from January to December, 2014. The cohort included both emergency and elective patients. There was no difference in the preoperative work-up as indicated. To perform the operation, a 2–2.5-cm linear incision was made through the umbilicus and the single port platform utilized. A 10 mm 30-degree laparoscope, a 5 mm LigaSure and straight instruments were used to perform the laparoscopic cholecystectomy procedure.

All patients except two were operated on successfully. Conversion was considered the placement of an additional epigastric/Right upper quadrant (RUQ) port. The conversion rate to standard LC was 7%. No patient was converted to open cholecystectomy. In the 28 successfully completed patients, the median duration of the operation was 38.5 min and estimated operative blood loss was 24 ml. Patients were commenced on liquid diet immediately on being fully conscious and after return to the ward with an estimated time of 6 h. The mean postoperative hospital stay was 1.4 days. Follow-up visits were conducted for all patients at 2-weeks intervals and continued for 6 weeks after surgery where possible. Two patients developed wound infections. All patients were satisfied with the good cosmetic effect of the surgery. The total satisfaction rate was 100%.

SILC is a safe and feasible technique for operating with scarless outcomes and reducing perioperative discomfort at the same time. The GelPOINTTM is a safe and feasible platform to be used. The procedure can be accomplished using regular instruments and laparoscope. Curved instruments and a bariatric length laparoscope may make the procedure easier and result in greater time saving. The addition of LigaSure™ decreases the complexity of the operation, decreases operative time and blood loss. The technique is economical in a resource-limited environment.

Adverse events because of medical errors are a leading cause of death in the United States (US) exceeding the mortality rates of motor vehicle accidents, breast cancer, and AIDS. Improvements can and should be made to reduce the rates of preventable surgical errors because they account for nearly half of all adverse events within hospitals. Although minimally invasive surgery (MIS) has proven patient benefits such as reduced postoperative pain and hospital stay, its operative environment imposes substantial physical and cognitive strain on the surgeon increasing the risk of error. To mitigate errors and protect patients, a multidisciplinary approach is needed to improve MIS. Clinical human factors, and biomedical engineering principles and methodologies can be used to develop and assess laparoscopic surgery instrumentation, practices, and procedures. First, the foundational understanding and the imperative to transform health care into a high-quality and safe system is discussed. Next, a generalized perspective is presented on the impact of the design and redesign of surgical technologies and processes on human performance. Finally, the future of this field and the research needed to further improve the quality and safety of MIS is discussed.

AIM: To assesse the rate of bile duct injuries (BDI) and overall biliary complications during single-port laparoscopic cholecystectomy (SPLC) compared to conventional laparoscopic cholecystectomy (CLC).

METHODS: SPLC has recently been proposed as an innovative surgical approach for gallbladder surgery. So far, its safety with respect to bile duct injuries has not been specifically evaluated. A systematic review of the literature published between January 1990 and November 2012 was performed. Randomized controlled trials (RCT) comparing SPLC versus CLC reporting BDI rate and overall biliary complications were included. The quality of RCT was assessed using the Jadad score. Analysis was made by performing a meta-analysis, using Review Manager 5.2. This study was based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. A retrospective study including all retrospective reports on SPLC was also performed alongside.

RESULTS: From 496 publications, 11 RCT including 898 patients were selected for meta-analysis. No studies were rated as high quality (Jadad score ≥ 4). Operative indications included benign gallbladder disease operated in an elective setting in all studies, excluding all emergency cases and acute cholecystitis. The median follow-up was 1 mo (range 0.03-18 mo). The incidence of BDI was 0.4% for SPLC and 0% for CLC; the difference was not statistically different (P = 0.36). The incidence of overall biliary complication was 1.6% for SPLC and 0.5% for CLC, the difference did not reached statistically significance (P = 0.21, 95%CI: 0.66-15). Sixty non-randomized trials including 3599 patients were also analysed. The incidence of BDI reported then was 0.7%.

CONCLUSION: The safety of SPLC cannot be assumed, based on the current evidence. Hence, this new technology cannot be recommended as standard technique for laparoscopic cholecystectomy.

Objective. To report our experience treating adnexal masses using a combination of the SILS port and straight nonroticulating laparoscopic instruments. Study Design. This prospective feasibility study included 14 women with symptomatic and persistent adnexal masses. Removal of adnexal masses via single-incision laparoscopic surgery using a combination of the SILS port and straight nonroticulating laparoscopic instruments was performed. Results. All of the patients had symptomatic complex adnexal masses. Mean age of the patients was 38.4 years (range: 21–61 years) and mean duration of surgery was 71 min (range: 45–130 min). All surgeries were performed using nonroticulating straight laparoscopic instruments. Mean tumor diameter was 6 cm (range: 5–12 cm). All patient pathology reports were benign. None of the patients converted to laparotomy. All the patients were discharged on postoperative d1. Postoperatively, all the patients were satisfied with their incision and cosmetic results. Conclusion. All 14 patients were successfully treated using standard, straight nonroticulating laparoscopic instruments via the SILS port. This procedure can reduce the cost of treatment, which may eventually lead to more widespread use of the SILS port approach. Furthermore, concomitant surgical procedures are possible using this approach. However, properly designed comparative studies with single port and classic laparoscopic surgery are urgently needed.

The aim of this study was to establish the incidence of postoperative complications after single incision laparoscopic cholecystectomy.

A literature search was performed using the PubMed database. Search terms included single incision laparoscopic cholecystectomy, single port cholecystectomy, minimal invasive laparoscopic cholecystectomy, nearly scarless cholecystectomy and complications.

A total of 38 articles meeting the selection criteria were reviewed. A total of 1180 patients were selected to undergo single incision laparoscopic cholecystectomy. Introduction of extra ports was necessary in 4% of the patients. Conversion to open cholecystectomy was required in 0.4% of the patients. Laparoscopic cholangiography was attempted in 4% of the patients. The incidence of major complications requiring surgical intervention or ERCP with stenting was 1.7%. The mortality rate was zero.

Although the number of complications after single incision laparoscopic cholecystectomy seems favourable, it is too early to conclude that single incision laparoscopic cholecystectomy is a safe procedure. Large randomised controlled trials will be necessary to further establish its safety.

Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.
