Methods of cystic duct occlusion during laparoscopic cholecystectomy

High rate of stone-related complications after stapling the cystic duct during laparoscopic cholecystectomy-an underrecognized risk

BACKGROUND

Laparoscopic staplers (LS) have been suggested as a safe alternative to metal clips in laparoscopic cholecystectomy when the cystic duct is too inflamed or wide for complete clip occlusion. We aimed to evaluate the perioperative outcomes of patients whose cystic ducts were controlled by LS and evaluate the risk factors for complications.

METHODS

Patients who underwent laparoscopic cholecystectomy with LS used to control the cystic duct from 2005 to 2019 were retrospectively identified from an institutional database. Patients were excluded for open cholecystectomy, partial cholecystectomy, or cancer. Potential risk factors for complications were assessed using logistic regression analysis.

RESULTS

Among 262 patients, 191 (72.9%) were stapled for size and 71 (27.1%) for inflammation. In total, 33 (16.3%) patients had Clavien-Dindo grade ≥ 3 complications, with no significant difference when surgeons chose to staple for duct size versus inflammation (p = 0.416). Seven patients had bile duct injury. A large proportion had Clavien-Dindo grade ≥ 3 postoperative complications specifically related to bile duct stones [n = 29 (11.07%)]. Intraoperative cholangiogram was protective against postoperative complications [odds ratio (OR) = 0.18 (p = 0.022)].

CONCLUSION

Whether these high complication rates reflect a technical issue with stapling, more challenging anatomy, or worse disease, findings question whether the use of LS during laparoscopic cholecystectomy is truly a safe alternative to the already accepted methods of cystic duct ligation and transection. Based on these findings, an intraoperative cholangiogram should be performed when considering a linear stapler during laparoscopic cholecystectomy to: (1) ensure the biliary tree is free of stones; (2) prevent inadvertent transection of the infundibulum rather than the cystic duct; and, (3) allow opportunity for safe alternative strategies when an IOC is not able to confirm anatomy. Otherwise, surgeons employing LS devices should be aware that patients are at higher risk for complications.

[Evidence-based medicine of gallstone disease regarding development of national clinical guidelines]

OBJECTIVE

To study the Cochrane evidence base of systematic reviews and meta-analyses regarding development of national guidelines for surgical treatment of gallstone disease and its complications.

MATERIAL AND METHODS

We analyzed the original database involving 35 systematic reviews and meta-analyses of Cochrane Library devoted to gallstone disease and its complications. Methodology of electronic and manual searching of trials was used for identification and screening of information for the period until October 2021.

RESULTS

There were 430 randomized controlled trials from different countries estimated in 35 systematic reviews of Cochrane Library. At the same time, Russian-language researches are not included in the world's evidence database of biliary tract surgery. Expert groups couldn't perform meta-analysis and limited to systematic-review in 6 (17%) publications because of insufficient statistical power or primary researches. Need for further research of this issue was determined after assessment of 26 (74%) meta-analyses.

CONCLUSION

We have to convey foreign experience as subbase of national clinical guidelines taking into account deficiency of scientific trials with high level of evidence in our country. Need for further evidence trials, considering the peculiarities of surgical care in the Russian Federation, is determined by unsolved issues of treatment of gallstone disease and its complications.

Bile leakage after loop closure vs clip closure of the cystic duct during laparoscopic cholecystectomy: A retrospective analysis of a prospective cohort

BACKGROUND

Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical procedures. Cystic stump leakage is an underestimated, potentially life threatening complication that occurs in 1%-6% of the patients. With a secure cystic duct occlusion technique during LC, bile leakage becomes a preventable complication.

AIM

To investigate the effect of polydioxanone (PDS) loop closure of the cystic duct on bile leakage rate in LC patients.

METHODS

In this retrospective analysis of a prospective cohort, the effect of PDS loop closure of the cystic duct on bile leakage complication was compared to patients with conventional clip closure. Logistic regression analysis was used to develop a risk score to identify bile leakage risk. Leakage rate was assessed for categories of patients with increasing levels of bile leakage risk.

RESULTS

Of the 4359 patients who underwent LC, 136 (3%) underwent cystic duct closure by a PDS loop. Preoperatively, loop closure patients had significantly more complicated biliary disease compared to the clipped closure patients. In the loop closure cohort, zero (0%) bile leakage occurred compared to 59 of 4223 (1.4%) clip closure patients. For patients at increased bile leakage risk (risk score ≥ 1) rates were 1.6% and up to 13% (4/30) for clip closure patients with a risk score ≥ 4. This risk increase paralleled a stepwise increase of actual bile leakage complication for clip closure patients, which was not observed for loop closure patients.

CONCLUSION

Cystic duct closure with a PDS loop during LC may reduce bile leakage in patients at increased risk for bile leakage.

Optimising Surgical Technique in Laparoscopic Cholecystectomy: a Review of Intraoperative Interventions

BACKGROUND

Laparoscopic cholecystectomy (LC) is one of the most commonly performed procedures worldwide but there is considerable variance amongst surgeons regarding intraoperative technique. This review aims to provide a comprehensive summary, with evidence-based recommendations, of intraoperative interventions in LC.

METHODS

A literature search was performed using PubMed, EMBASE, Google Scholar and Cochrane Review databases. Articles were screened for eligibility with inclusion criteria based on study design, surgical approach, surgical timing, pathology and intervention type. The most contemporary, comprehensive or relevant articles were used as the primary evidence for the final analysis and discussion.

RESULTS

A total of 25 systematic reviews and/or meta-analyses and 19 individual trials were identified from the literature and grouped into ten clinical intervention topics. Three intraoperative interventions offer clinical benefit and are recommended: wound/intraperitoneal local anaesthetic, low-pressure pneumoperitoneum and manoeuvres to reduce residual pneumoperitoneum. No benefit was demonstrated for routine subhepatic drain placement and gallbladder aspiration. Techniques which appear to demonstrate improvements but do not translate into clinical efficacy are the use of warmed/humidified carbon dioxide, installation of intraperitoneal saline and the use of advanced imaging techniques. Techniques demonstrating equipoise, and for which no recommendations can be made, are type of energy source and cystic duct occlusion methods.

DISCUSSION

This review highlights and suggests specific intraoperative techniques during uncomplicated LC that should be employed, avoided or considered by the individual surgeon. Optimising surgical technique in this way can lead to improved patient outcomes.

Systematic review of cystic duct closure techniques in relation to prevention of bile duct leakage after laparoscopic cholecystectomy

AIM

To study the effect of different techniques of cystic duct closure on bile leakage after laparoscopic cholecystectomy (LC) for biliary disease.

METHODS

A systematic search of MEDLINE, Cochrane and EMBASE was performed. Rate of cystic duct leakage (CDL) was the primary outcome. Risk of bias was evaluated. Odds ratios were analyzed for comparison of techniques and pooled event rates for non-comparative analyses. Pooled event rates were compared for each of included techniques.

RESULTS

Out of 1491 articles, 38 studies were included. A total of 47491 patients were included, of which 38683 (81.5%) underwent cystic duct closure with non-locking (metal) clips. All studies were of low-moderate methodological quality. Only two studies reported separate data on uncomplicated and complicated gallbladder disease. For overall CDL, an odds ratio of 0.4 (95%CI: 0.06-2.48) was found for harmonic energy vs clip closure and an odds ratio of 0.17 (95%CI: 0.03-0.93) for locking vs non-locking clips. Pooled CDL rate was around 1% for harmonic energy and metal clips, and 0% for locking clips and ligatures.

CONCLUSION

Based on available evidence it is not possible to either recommend or discourage any of the techniques for cystic duct closure during LC with respects to CDL, although data point out a slight preference for locking clips and ligatures vs other techniques. No separate recommendation can be made for complicated gallbladder disease.

The Safety and Efficacy of Clipless versus Conventional Laparoscopic Cholecystectomy - our Experience in an Indian Rural Center

Background

Laparoscopic cholecystectomy is one of the most common surgeries performed nowadays. There are lot of advances in closure of cystic duct and artery (clip ligation, suture ligation), but it remains an enigma regarding efficacy, safety and postoperative complications for using non-absorbable suture material or Liga clip for the operating surgeon in laparoscopic cholecystectomy.

Objectives

Our study aimed to evaluate the efficacy, safety and complications of non-absorbable sutures ligation versus clips application in laparoscopic cholecystectomy, and to compare the operative time and cost effectiveness of the two surgical approaches in laparoscopic cholecystectomy.

Methods

This prospective study was performed between August 2014 and February 2015 in M. M. Institute of Medical Science and Research, in a rural center, Mullana, India. The study included 160 patients who were diagnosed with chronic cholecystitis in a single unit. Subjects were divided into two groups and all cases were operated by a single surgeon. The cystic pedicle was tied with non-absorbable material (silk 2-0) in group A and with Titanium clips using a clip applicator in group B.

Results

The application of silk and clips for cystic duct and artery ligation in laparoscopic cholecystectomy can be safely used. The mean time for ligation of cystic duct was 2.50 (SD ±0.25) in group A and 1.50 min (SD ±1.85) in group B, with P<0.001, which was significant. Similarly, the mean time for ligation of cystic artery was 1.50 min (SD±0.20) in group A and 1.36 min (SD ±0.11) in group B, with P>0.001. There were no postoperative complications, such as wound infection or bile leakage, in any of the two methods. The cost of material for silk suture (40-60 Rupees or 0.62-0.92 $) is definitely much lower than that for Liga clips (790-1000 Rupees or 12.28-15.55 $). For the use of clips, a clip applicator is required, but in case of silk ligation no special instrument is required and silk is also easily available.

Conclusion

In laparoscopic cholecystectomy, ligation of cystic duct and cystic artery with clips takes less time than by silk suture. We conclude that both ligation techniques can be safely and effectively used. Training for junior surgeons is necessary to avoid potential complications.

Laparoscopic cholecystectomy: consensus conference-based guidelines

INTRODUCTION

Laparoscopic cholecystectomy (LC) is the gold standard technique for gallbladder diseases in both acute and elective surgery. Nevertheless, reports from national surveys still seem to represent some doubts regarding its diffusion. There is neither a wide consensus on its indications nor on its possible related morbidity. On the other hand, more than 25 years have passed since the introduction of LC, and we have all witnessed the exponential growth of knowledge, skill and technology that has followed it. In 1995, the EAES published its consensus statement on laparoscopic cholecystectomy in which seven main questions were answered, according to the available evidence. During the following 20 years, there have been several additional guidelines on LC, mainly focused on some particular aspect, such as emergency or concomitant biliary tract surgery.

METHODS

In 2012, several Italian surgical societies decided to revisit the clinical recommendations for the role of laparoscopy in the treatment of gallbladder diseases in adults, to update and supplement the existing guidelines with recommendations that reflect what is known and what constitutes good practice concerning LC.

Prevention and treatment of bile duct injuries during laparoscopic cholecystectomy: the clinical practice guidelines of the European Association for Endoscopic Surgery (EAES)

BACKGROUND

Laparoscopic cholecystectomy is one of the most common surgical procedures in Europe (and the world) and has become the standard procedure for the management of symptomatic cholelithiasis or acute cholecystitis in patients without specific contraindications. Bile duct injuries (BDI) are rare but serious complications that can occur during a laparoscopic cholecystectomy. Prevention and management of BDI has given rise to a host of publications but very few recommendations, especially in Europe.

METHODS

A systematic research of the literature was performed. An international expert panel was invited to appraise the current literature and to develop evidence-based recommendations. Statements and recommendations were drafted after a consensus development conference in May 2011, followed by presentation and discussion at the annual congress of the EAES held in Torino in June 2011. Finally, full guidelines were consented and adopted by the expert panel via e-mail and web conference.

RESULTS

A total of 1,765 publications were identified through the systematic literature search and additional submission by panellists; 671 publications were selected as potentially relevant. Only 46 publications fulfilled minimal methodological criteria to support Clinical Practice Guidelines recommendations. Because the level of evidence was low for most of the studies, most statements or recommendations had to be based on consensus of opinion among the panel members. A total of 15 statements and recommendations were developed covering the following topics: classification of injuries, epidemiology, prevention, diagnosis, and management of BDI.

CONCLUSIONS

Because BDI is a rare event, it is difficult to generate evidence for prevention, diagnosis, or the management of BDI from clinical studies. Nevertheless, the panel has formulated recommendations. Due to the currently limited evidence, a European registry should be considered to collect and analyze more valid data on BDI upon which recommendations can be based.

Laparoscopic cholecystectomy under field conditions in Asiatic black bears (Ursus thibetanus) rescued from illegal bile farming in Vietnam

Nine adult Asiatic black bears (Ursus thibetanus) previously rescued from illegal bile farming in Vietnam were examined via abdominal ultrasound and exploratory laparoscopy for liver and gall bladder pathology. Three bears demonstrated notable gall bladder pathology, and minimally invasive cholecystectomies were performed using an open laparoscopic access approach, standard 10 to 12 mmHg carbon dioxide pneumoperitoneum and a four-port technique. A single bear required insertion of an additional 5 mm port and use of a flexible liver retractor due to the presence of extensive adhesions between the gall bladder and quadrate and left and right medial liver lobes. The cystic duct was dissected free and this and the cystic artery were ligated by means of extracorporeal tied Meltzer knot sutures. The gall bladder was dissected free of the liver by blunt and sharp dissection, aided by 3.8 MHz monopolar radiosurgery. Bears that have had open abdominal cholecystectomies are reported as taking four to six weeks before a return to normal activity postoperatively. In contrast, these bears demonstrated rapid unremarkable healing, and were allowed unrestricted access to outside enclosures to climb trees, swim and interact normally with other bears within seven days of surgery.
