Single incision laparoscopic surgery

As a complement to standard laparoscopic surgery and a safe alternative to natural orifice transluminal endoscopic surgery,single incision laparoscopic surgery is gaining popularity.There are expensive ports,disposable hand instruments and flexible endoscopes that have been suggested to do this surgery and would increase the cost of operation.For a simple surgery like laparoscopic cholecystectomy,these extras are not needed and the surgery can be performed using standard ports,instruments and telescopes.Triangular port insertion and use of instruments by the "chop stick method" are recommended to successfully do the procedure as we have done in our so far small series of 40 cases.

Single incision laparoscopic liver resection： a case report

Laparoscopic procedure as a minimally invasive surgery has been introduced into many abdominal surgeries. Smaller incisions of the abdominal wall reduce postoperative pain and the risk of wound complications, and provide an excellent cosmetic result compared with open surgery. Natural orifice transluminal endoscopic surgery （NOTES）, a no-scar surgery, is a hot spot of modern surgery. However,

Utility of single-incision totally extraperitoneal inguinal hernia repair with intraperitoneal inspection

AIM To study the utility of single-incision totally extraperitoneal inguinal hernia repair with intraperitoneal inspection.METHODS A 2 cm transverse skin incision was made in the umbilicus, extending to the intraperitoneal cavity. Carbon dioxide was insufflated followed by insertion of laparoscope to observe the intraperitoneal cavity. The type of hernia was diagnosed and whether there was the presence of intestinal incarceration was confirmed. When an intestinal incarceration in the hernia sac was found, the forceps were inserted through the incision site and the intestine was returned to the intraperitoneal cavity without increasing the number of trocars. Once the peritoneum was closed, totally extraperitoneal inguinal hernia repair was performed, and finally, intraperitoneal observation was performed to reconfirm the repair.RESULTS Of the 75 hernias treated, 58 were on one side, 17 were on both sides, and 10 were recurrences. The respective median operation times for these 3 groups of patients were 100 min(range, 66 to 168), 136 min(range, 114 to 165), and 125 min(range, 108 to 156), with median bleeding amounts of 5 g(range, 1 to 26), 3 g(range, 1 to 52), and 5 g(range, 1 to 26), respectively. Intraperitoneal observation showed hernia on the opposite side in 2 cases, intestinal incarceration in 3 cases, omental adhesion into the hernia sac in 2 cases, severe postoperative intraperitoneal adhesions in 2 cases, and bladder protrusion in 1 case. There was only 1 case of recurrence.CONCLUSION Single-incision totally extraperitoneal inguinal hernia repair with intraperitoneal inspection makes hernia repairs safer and reducing postoperative complications. The technique also has excellent cosmetic outcomes.

Single incision laparoscopic cholecystectomy using the one-incision three-trocar technique with all straight instruments:how I do it?

Single incision laparoscopic surgery(SILS)is a novel minimally invasive surgical technique that is gaining popularity around the world.One of the most commonly performed procedures is single incision laparoscopic cholecystectomy(SILC).Most reported techniques utilize special purpose-made access port and articulating instruments,rendering the procedure costly and difficult to learn.This article provides a stepwise description of SILC technique using all straight instruments without the need for a special port.It aims to shorten the learning curve for surgeons wishing to adopt a safe and cost-effective SILC technique to their practice.

Medium-term clinical efficacy and safety of single incision and modified trans-obturator mid-urethral slings for female stress urinary incontinence

Aims:To evaluate the medium term efficacy and safety of Altis and Solyx single incision slings(SIS)compared with tension-free vaginal tape(TVT)Abbrevo trans-obturator sling.We hypothesize that both SIS show little difference in efficacy and safety and perform similarly to TVT Abbrevo.Methods:We conducted an ambispective comparative cohort study of women with stress urinary incontinence who received a SIS in comparison to matched TVT Abbrevo subjects from a concurrent randomized controlled trial(RCT).Subjects were identified retrospectively,and prospectively invited for examination and questionnaires>12 months post-operatively.Exclusions included intrinsic sphincter deficiency,previous sling surgery,and others.Primary outcome was subjective cure[negative response to International Consultation Incontinence Questionnaire-Urinary Incontinence Short Form(ICIQ-UI SF)question 6,leakage during coughing/activity].Secondary outcomes include objective cure(negative cough stress test),functional outcomes,and adverse events.Results:Between 2012 and 2018,a total of 113 women received one of two SIS surgeries;Solyx(n=50)followed by the Altis(n=63);104 were available for final efficacy analysis.Mean follow-up was 21.7(Altis),46.0(Solyx),and 29.0(Abbrevo)months.Baseline characteristics were comparable between the groups.There was no significant differences in the subjective or objective cure rates between the groups,and no differences in functional outcomes such as patient global impression of improvement,and post-operative ICIQ-UI SF score.There was a low rate of mesh related complications and no differences seen between the groups.Conclusions:Despite being an underpowered study,Altis and Solyx SIS have favourable efficacy and safety profiles which are comparable to an established trans-obturator mid-urethral slings(MUS).

Single access laparoscopic total colectomy for severe refractory ulcerative colitis

BACKGROUND Single port laparoscopic surgery allows total colectomy and end ileostomy for medically uncontrolled ulcerative colitis solely via the stoma site incision.While intuitively appealing,there is sparse evidence for its use beyond feasibility.AIM To examine the usefulness of single access laparoscopy(SAL)in a general series experience of patients sick with ulcerative colitis.METHODS All patients presenting electively,urgently or emergently over a three-year period under a colorectal specialist team were studied.SAL was performed via the stoma site on a near-consecutive basis by one surgical team using a“surgical glove port”allowing group-comparative and case-control analysis with a contemporary cohort undergoing conventional multiport surgery.Standard,straight rigid laparoscopic instrumentation were used without additional resource.RESULTS Of 46 consecutive patients requiring surgery,39(85%)had their procedure begun laparoscopically.27(69%)of these were commenced by single port access with an 89%completion rate thereafter(three were concluded by multi-trocar laparoscopy).SAL proved effective in comparison to multiport access regardless of disease severity providing significantly reduced operative access costs(>100€case)and postoperative hospital stay(median 5 d vs 7.5 d,P=0.045)without increasing operative time.It proved especially efficient in those with preoperative albumin>30 g/dL(n=20).Its comparative advantages were further confirmed in ten pairs case-matched for gender,body mass index and preoperative albumin.SAL outcomes proved durable in the intermediate term(median follow-up=20 mo).CONCLUSION Single port total colectomy proved useful in planned and acute settings for patients with medically refractory colitis.Assumptions regarding duration and cost should not be barriers to its implementation.

Laparoscopic common bile duct exploration to treat choledocholithiasis in situs inversus patients:A technical review

Situs inversus(SI)is a rare congenital condition characterized by a mirror-image transposition of the major visceral organs.Since the 1990s,more than one hundred SI patients have been reported to have successfully undergone laparoscopic cholecystectomy.In these cases,the major problem is to overcome is the left-right condition for right-handed surgeons.Laparoscopic common bile duct exploration(LCBDE),an alternative to treat patients with bile duct stones,has shown equivalent efficacy and is less likely to cause pancreatitis than endoscopic retrograde cholangiopancreatography.Recent updated meta-analyses revealed that a shorter postoperative hospital stay,fewer procedural interventions,cost-effectiveness,a higher stone clearance rate,and fewer perioperative complications are additional advantages of LCBDE.However,the technique is technically demanding,even for skilled laparoscopic surgeons.Conducting LCBDE in patients with difficult situations,such as SI,is more complex than usual.We herein review published SI patients with choledocholithiasis treated by LCBDE,including our own experience,and this paper focuses on the technical aspects.
