Transumbilical single-incision laparoscopic cholecystectomy: long-term review from a single center

Evolution of minimally invasive cholecystectomy: a narrative review

BACKGROUND

Laparoscopic cholecystectomy, being a prevalent abdominal surgical procedure, has transitioned through various innovative stages aimed at reducing the procedure's invasiveness. These stages encompass Single-Incision Laparoscopic Cholecystectomy (SILC), Mini Laparoscopic Cholecystectomy (MLC), Natural Orifice Transluminal Endoscopic Surgery (NOTES), and Robotic-Assisted Laparoscopic Cholecystectomy (RALC). The purpose of this review is to trace the evolution of minimally invasive cholecystectomy techniques, assess their status, and identify emerging trends and challenges in the field.

METHOD

An extensive review was performed to explore the evolution and characteristics of SILC, MLC, NOTES, and RALC. The approach involved an in-depth examination of literature available on PubMed, coupled with a critical assessment of surgical outcomes, associated complications, and technical hurdles posed by these methods.

RESULTS

SILC, despite its potential for reduced scarring, exhibits an elevated risk of bile duct damage and incisional hernia occurrences. MLC, mirroring the standard technique closely, presents minor benefits without amplifying postoperative complications, hence, positing itself as a feasible choice for routine elective cholecystectomy. NOTES, although still facing technical challenges, the hybrid transvaginal procedure is gaining clinical interest. RALC, heralded for its augmented precision and dexterity, emerges as a potential future avenue, although necessitating further exploration to ascertain its efficacy and safety.

CONCLUSION

The progression of laparoscopic cholecystectomy methodologies embodies the surgical society's aspiration to minimize invasiveness whilst enhancing patient outcomes. This review endeavors to offer a structured discourse on SILC, MLC, NOTES, and RALC, aspiring to aid the ongoing deliberation on the judicious selection of surgical techniques in clinical practice.

Routine single-incision laparoscopic common bile duct exploration with concomitant cholecystectomy for elderly patients: a 6-year retrospective comparative study

BACKGROUND

While single-incision laparoscopic cholecystectomy (SILC) has gained more popularity in recent years, its application to elderly patients needs further evaluation. Few SILC studies regarded this rapidly growing vulnerable population, and single-incision laparoscopic common bile duct exploration (SILCBDE) was never mentioned. We conducted an observational study of 146 routine SILCBDE to address this issue.

METHODS

One hundred forty-six consecutive patients underwent SILCBDE with concomitant cholecystectomies during a period of 6 years (July 2012-June 2016 and July 2018-July 2020). Forty patients with an age of 65 years or older were the study target. Characteristics and operative outcomes were compared with the remaining 106 younger patients by retrospective chart review. The primary outcomes include complications and mortality, while the secondary outcomes contain intraoperative blood loss, operative time, procedural conversions, postoperative length of hospital stay, and bile duct stone recurrence.

RESULTS

There was no mortality. The bile duct stone clearance rate was 98.6%. The elderly group had higher American Society of Anesthesiologists (ASA) scores, higher comorbidity rate, higher acute cholangitis rate, lower completion intraoperative cholangiography (IOC) rate, longer operative time, more blood loss, longer postoperative hospital stay (p < .001), longer total hospital stay (p < .001), higher procedural conversion rate (p < .05), higher complication rate (p < .001), and the exclusive open conversion (2.5%). The difference in complications derived from Clavien-Dindo grade I.

CONCLUSION

Routine SILCBDE with concomitant cholecystectomy by experienced surgeons is safe and efficacious for elderly patients as for younger patients. Randomized controlled trials are anticipated.

Low long-term incidence of incisional hernia after cholecystectomy: A systematic review with meta-analysis

BACKGROUND

Various surgical approaches are available for cholecystectomy, but their long-term outcomes, such as incidence of incisional hernia, are largely unknown. Our aim was to investigate the long-term incidence of incisional hernia after cholecystectomy for different surgical approaches.

METHODS

This systematic review and meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42020178906). Three databases were searched for original studies on long-term complications of cholecystectomy with n > 40 and follow-up ≥6 months for incisional hernia. Risk of bias within the studies was assessed using the Newcastle-Ottawa Scale and the Cochrane "risk of bias" tool. Meta-analysis of the incidence of incisional hernia after 6 and 12 months was conducted when possible.

RESULTS

We included 89 studies. Of these, 77 reported on multiport or single-incision laparoscopic cholecystectomy. Twelve studies reported on open cholecystectomy and 4 studies on robotic cholecystectomy. Weighted mean incidence proportion of incisional hernia after multi-port laparoscopic cholecystectomy was 0.3% (95% confidence interval 0-0.6) after 6 months and 0.2% after 12 months (95% confidence interval 0.1-0.3). Weighted mean incidence of incisional hernia 12 months postoperatively was 1.5% (95% confidence interval 0.4-2.6) after open cholecystectomy and 4.5% (95% confidence interval 0.4-8.6) after single-incision laparoscopic cholecystectomy. No meta-analysis could be conducted for robotic cholecystectomy, but incidences ranged from 0% to 16.7%.

CONCLUSION

We found low 1-year incidences of incisional hernia after multiport laparoscopic and open cholecystectomy, whereas risks of incisional hernia were considerably higher after single-incision laparoscopic and robotic cholecystectomy.

Analysis of post-operative complication in single-port laparoscopic cholecystectomy: A retrospective analysis in 817 cases from a surgeon

BACKGROUND

Single-port laparoscopic cholecystectomy (SPLC) is a new advanced technique in laparoscopic surgery which has many benefits according to previous reports. The purpose of this study was to present personal experiences with SPLC in >800 cases performed by a surgeon to evaluate the safety and feasibility of this procedure.

MATERIALS AND METHODS

A retrospective review of 817 cases of SPLC was conducted. All patients had received elective SPLC by a surgeon in our centre during March 2009-August 2015. Our review suggests patients' character, peri-operative data and post-operative outcome.

RESULTS

Three hundred and ninety-eight men (48.7%) and 419 women (51.3%) with an average age of 48.3 years had received SPLC. Their mean body mass index (BMI) was 23.75 kg/m2. The mean operating time took 46.9 min (19-130). Seventy-nine cases (9.7%) needed additional port during operation. BMI, age and previous abdominal surgical history did not affect conversion to multiport surgery. Bile spillage during operation occurred in 73 cases (8.9%). There were 4 cases of open conversion because of bleeding (2 cases, 0.2%) and common bile duct (CBD) injury (2 cases, 0.2%). Mean duration of hospital stay was 2.36 days. We have experienced 38 cases (4.7%) of post-operative complication: 8 cases (1.0%) of major one and 30 cases (3.7%) of minor one. Major complication occurred in 3 cases (0.4%) of retained CBD stone, 3 cases (0.4%) of cystic duct leakage needed endoscopic retrograde cholangiopancreatography and 2 cases (0.2%) of CBD injury needed reoperation. Most minor complications were wound infections that have healed after conservative treatment. There were no post-operative mortalities.

CONCLUSION

SPLC is a safe and practicable technique. With surgical experience, criteria and area of SPLC can be broadened. SPLC is occupying a greater domain of a laparoscopic cholecystectomy.

Is Single-incision Laparoscopic Cholecystectomy Feasible for Acute Cholecystitis? A Consecutive Study of 60 Cases

The feasibility of single-incision laparoscopic cholecystectomy (SIL-C) for patients with acute cholecystitis were evaluated based on the timing of operation after onset of symptoms. Sixty patients with acute cholecystitis who underwent SIL-C were divided into 2 groups according to the timing of operation: group E included 23 patients who underwent SIL-C within 72 hours, and group O included 37 patients who underwent SIL-C later. There were no statistical differences between group E and group O in clinicopathologic characteristics. Group E demonstrated significantly shorter operating time and less blood loss than group O. Although the incidences of additional port(s) requirements were not significantly different, 8 patients in group O required open conversion, indicating significantly higher rate. As group E demonstrated favorable surgical outcomes compared with group O, SIL-C for acute cholecystitis seems to be a feasible therapeutic procedure when performed within 72 hours as updated Tokyo Guidelines recommended.
