Ismaeil DA. Avoidance of bile duct injury in laparoscopic cholecystectomy with feasible intraoperative resources: A cohort study. Biomed Rep 2024; 21:110. [PMID: 38872852 PMCID: PMC11168025 DOI: 10.3892/br.2024.1798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 05/08/2024] [Indexed: 06/15/2024] Open
Abstract
Laparoscopic cholecystectomy (LC) is one of the most commonly performed surgeries and is considered the standard treatment for cholelithiasis. However, it is associated with a risk of bile duct or hepatic artery injuries. This study evaluated the safety of LCs and the conversion rate (CR) by achieving a critical view of safety (CVS) and identification of Rouviere's sulcus (RS). This was a single-group cohort study that included consecutive patients undergoing LC at Smart Health Tower (Sulaimani, Iraq) from January 2021 to January 2023. The data were prospectively collected from patients' profiles or surgical notes within the hospital's database. A total of 419 patients underwent LC, of which females were the predominant gender (78.5%). The mean and median ages of the cases were 46.3±15.8 and 45 years, with a range of 2-90 years, respectively. The most common indications for surgery were biliary colic (69.5%), followed by acute cholecystitis (23.9%). The duration of the operations was significantly shorter for cases in which the CVS (45.6±17.9 min) or identification of RS (45.6±18.6 min) was achieved compared to those where the CVS (63.7±27.7 min) or RS (50.7±21.7 min) was not observed. Surgeries for patients with both CVS achievement and RS identification were also significantly less time-consuming (44.3±17.6) than counterparts (53.3±22.6). Among the cases without CVS achievement or RS identification (n=97, 23%), eight (8.2%) had adhesions, 12 (12.4%) had a distended gallbladder (GB) and 10 (10.3%) had thick GB walls. In addition, four (4.1%) experienced GB perforation, two (2.1%) had bleeding and one (1%) had stone spillage. There was no conversion. The achievement of CVS and identification of RS are practical landmarks in performing safe LC and decreasing the CR.

Abstract
The incidence of common bile duct injuries following laparoscopic cholecystectomy (LC) remains three times higher than that following open surgery despite numerous attempts to decrease intraoperative incidents by employing better training, superior surgical instruments, imaging techniques, or strategic concepts. This paper is a narrative review which discusses from a contextual point of view the need to standardise the surgical approach in difficult laparoscopic cholecystectomies, the main strategic operative concepts and techniques, complementary visualisation aids for the delineation of anatomical landmarks, and the importance of cognitive maps and algorithms in performing safer LC. Extensive research was carried out in the PubMed, Web of Science, and Elsevier databases using the terms "difficult cholecystectomy", "bile duct injuries", "safe cholecystectomy", and "laparoscopy in acute cholecystitis". The key content and findings of this research suggest there is high intersocietal variation in approaching and performing LC, in the use of visualisation aids, and in the application of safety concepts. Limited papers offer guidelines based on robust data and a timid recognition of the human factors and ergonomic concepts in improving the outcomes associated with difficult cholecystectomies. This paper highlights the most relevant recommendations for dealing with difficult laparoscopic cholecystectomies.

Abstract
INTRODUCTION Laparoscopic cholecystectomy (LC) is the most frequent surgical operation in general surgery. The focus of recent research has been on improving the procedure's safety. Over 80% of healthy livers have Rouviere's sulcus (RVS), which is a natural notch in the right lobe that is present in proximity to the confluence of the bile duct. It is frequently considered an important component of safety during LC. RVS demarcates the area of the common bile duct (CBD) from the liver bed for the gall bladder. This research intends to evaluate the frequency, its relation to CBD, and the critical view of safety (CVS) during LC. MATERIALS AND METHODS An observational study was performed in a cohort of 50 patients listed for LC between September 2021 and September 2022. The presence of RVS was confirmed after liver retraction and dissection commenced. After the creation of CVS, its relationship with CBD was documented. Additionally, the position of the cystic lymph node was also documented during the dissection. RESULTS The findings of this study revealed that out of 50 patients, only 40 (80%) had RVS. However, cystic lymph nodes were present more frequently in 48 (96%) patients. CVS was achieved in all the patients, and it revealed the presence of RVS above the cystic duct-CBD junction in 37 (74%), at the level of the junction in 11 (22%), and in two (4%) where the junction could not be demarcated. CONCLUSION RVS is a reliable marker to dissect laterally to CBD while doing LC, which does not require any dissection and can be appreciated early during the procedure. However, its presence along with the cystic lymph node gives a better anatomical understanding of the area of CBD, thereby assisting in conducting the procedure safely.

Abstract
BACKGROUND Principles of safe cholecystectomy include dissection of the hepatocystic triangle and identification of the bilio-vascular structures to achieve critical view of safety. The aim of the present study was to document the variations in anatomical landmarks and bilio-vascular structures exposed during laparoscopic cholecystectomy. METHODS All consecutive patients who underwent laparoscopic cholecystectomy were included in the study. Recommended techniques of safe cholecystectomy were followed. Rouviere's sulcus was classified into four types. Cystic duct was assessed for its length and diameter. A new classification was suggested for cystic artery. RESULTS Five hundred patients were included in the study. Critical view of safety was achieved in 463 (92.6%) patients. Type1 Rouviere's sulcus was the most common variant found in 263 (52.6%). Normal cystic duct was present in 339 (67.8%). Wide cystic duct of normal length was the most common variant found in 71 (14.2%). Single cystic artery supero-medial to cystic duct (type1-s) was the most common variant found in 384 (76.8%). Inferior cystic artery i.e. artery infero-lateral to cystic duct (type-2) was the second most common variant, found in 40 (8%). Multiple cystic arteries in the hepatocystic triangle were due either to early division of single cystic artery (type-1m) or double cystic artery (type-3). Aberrant right hepatic artery giving off a small cystic artery (type-4) was seen in 12 (2.4%). CONCLUSION Wide variation in the anatomical structures is noted when principles of safe laparoscopic cholecystectomy is followed. Awareness is paramount to avoid bilio-vascular injury during surgery.

Abstract
BACKGROUND An understanding of the impact of operative difficulty on operative process in laparoscopic cholecystectomy is lacking. The aim of the present study was to prospectively analyse digitally recorded laparoscopic cholecystectomy to assess the impact of operative technical difficulty on operative process. METHODS Video of laparoscopic cholecystectomy procedures performed at Christchurch Hospital, NZ and North Shore Private Hospital, Sydney Australia were prospectively recorded. Using a framework derived from a previously published standard process video was annotated using a standardized template and stratified by operative grade to evaluate the impact of grade on operative process. RESULTS 317 patients had their laparoscopic cholecystectomy operations prospectively recorded. Seventy one percent of these videos (n = 225) were annotated. Single ICC of operative grade was 0.760 (0.663-0.842 p < 0.010). Median operative time, rate of operative errors significantly increased and rate of CVS decreased with increasing operative grade. Significant differences in operative anatomy, operative process and instrumentation were seen with increasing grade. CONCLUSION Operative technical difficulty is accurately predicted by operative grade and this impacts on operative process with significant implications for both surgeons and patients. Consequently operative grade should be documented routinely as part of a culture of safe laparoscopic cholecystectomy.

Abstract
PURPOSE Liver is divided into four anatomical lobes presenting minor fissures and invisible major fissures. The prevalence of Accessory Fissures in liver ranges widely from 6 to 94%. The morphometric analysis of individual lobes is also scarce in literature. There have been instances where the surgeon has experienced some of these variations as a surprise during surgery as the existing data on the surface variations of liver is still contradictory. A sound knowledge of these variations would aid the surgeons and radiologists to circumvent the misdiagnosis and complications during surgeries. METHODS The study was conducted in 93 cadaveric livers. Minor liver fissures, Accessory fissures and lobes were noted and measured. The livers were classified according to the Netter's classification. The morphology of caudate and quadrate lobes was studied. Any other variations in the appearance of groove for Inferior vena cava, gall bladder and its fossa were also studied. The results are tabulated. RESULTS The study revealed several variations in the morphological features of liver. Accessory fissures were noted in 51.61% of livers, distributed on various liver surfaces. Accessory lobes were noted in 27.9%. Pons hepatis was present in 22.5%. Gall bladder variations that were noted include the Hartmann's pouch (n = 14; 15.05%) and the Phrygian cap (n = 2; 2.15%). 65.6% livers (n = 61) had the sulcus of the caudate process or fissure of Gans or Rouviere sulcus which is a normal fissure present in majority of normal healthy livers. CONCLUSION The current study provides a complete understanding and a thorough knowledge of surface morphological variations in liver. We hope that this will be greatly helpful for surgeons and radiologists to avoid possible errors in interpretations, to plan appropriately and assist during liver surgeries and to do radiological interventions.

Abstract
The hallmark of evidence-based medicine is the meta-analysis (MA). For much of its rich history, the field of anatomy has been dominated by descriptive, cadaveric studies. In the last two decades, quantitative measurements and statistical analyses have frequently accompanied such studies. These studies have directly led to the publication of anatomical MAs, which have ushered in the exciting field of evidence-based anatomy. Although critical appraisal tools exist for clinical MAs, none of them are specifically tailored for anatomical MAs. Therefore, the purpose of this paper is to provide a framework by which clinical anatomists and others can critically appraise anatomical MAs using the Critical Appraisal Tool for Anatomical Meta-analysis (CATAM). Using a running example from a recently published MA, we show how to use the CATAM rubric in a step-by-step fashion. Each scored section of the CATAM rubric is summated into a total score (maximum 50 points). This score is then referenced to a conversion chart, which assigns a qualitative value to the MA in a range from "very good" to "poor." Future studies can investigate the interrater reliability of the instrument, and possibly subject the CATAM rubric to a Delphi panel. As anatomical MAs become more commonplace at surgical grand rounds and journal clubs in academic medical centers throughout the world, we hope that the CATAM rubric can help facilitate meaningful discussions about the quality and clinical relevance of anatomical MAs.

Abstract
Laparoscopic cholecystectomy has many advantages over open surgery. Nevertheless, incidence of intraoperative bile duct injury is consistently higher for laparoscopic technique. This review is devoted to modern principles of identifying the anatomical elements in hepatoduodenal ligament and rules for safe tissue dissection in this area. The last ones mainly consist in formation of «critical view of safety» before clipping and transection of tubular structures. The key for «critical view of safety» is mobilization of fatty and fibrous tissues of hepatocystic triangle starting from the lower third of the gallbladder.

Abstract
The purpose of this study was to determine the prevalence and to investigate the morphology of the sulcus of the caudate process in a Greek population, along with a systematic review and meta-analysis of the literature. Overall, 103 consecutive patients undergoing laparoscopic cholecystectomy were included in the analysis. The sulcus was present in 91% and three morphological variants were identified (groove 69%, slit 21% and scar 10%). The sulcus had a horizontal course in 90% of patients and a mean length of 25 ± 13 mm. The meta-analysis included 27 surgical and 11 cadaveric studies with 6661 cases in total. The pooled prevalence of the sulcus was 80% and did not differ significantly among various geographical regions. Concerning sulcus subtypes, the binary "open/fused" classification was used to unify the heterogeneous data. The "open" type was more frequent than the "fused" (64.5% vs 35.5%). A horizontal course was observed in 53.5% and an oblique in 45.7%. The sulcus contained the right portal pedicle in 38%, the right posterior portal pedicle in 37%, and the right posteroinferior pedicle in 23.5%. In conclusion, the sulcus of the caudate process is a very helpful anatomical landmark in hepatectomy and laparoscopic cholecystectomy and can be identified in the majority of patients. However, various classifications for the morphological variants and diverse terminology cause discrepancy in the literature and create the need for a single classification system. The proposed 3-tier classification (groove, slit, scar) is simple and easy to remember and avoids ambiguous nomenclature.

Abstract
Post-cholecystectomy bile duct injury is a serious complication. Usually, it results from structural misidentification and can be avoided by adopting the critical view of safety. The biliary, vascular, and other visceral injuries can also occur during the dissection to achieve the critical view of safety. To avoid such complication, identification of the safe area for dissection is important during laparoscopic cholecystectomy. It is imperative to start the dissection in a safe area and remain there during the procedure. Fixed anatomical landmarks can help in proper orientation to ascertain the surgical anatomy correctly during surgery. The Rouviere's sulcus is one of such anatomical landmarks. Utilizing this sulcus, we describe a technique of zonal demarcation based on the concept of one line (the R4U line), two planes (the R4U planes), and four zones to identify a "safe area" for dissection during laparoscopic cholecystectomy to perform the procedure safely.

Abstract
INTRODUCTION Even though the prevalence of bile duct injury (BDI) is nowadays lower than before and close to the era of open cholecystectomy, there is a strong need to make it even lower. B-SAFE is a group of five visual landmarks that may be used before dissection in the hepatocystic triangle for better orientation around the gallbladder. Another method is laparoscopic ultrasound (LUS), which enables confirmation of structures in the hepatoduodenal ligament and delineation of the safe plane of dissection. AIM To evaluate the use of B-SAFE and ultrasonographic landmarks during laparoscopic cholecystectomy in navigation around the gallbladder. MATERIAL AND METHODS The study group consisted of 158 patients with symptomatic cholecystolithiasis. The methods of intraoperative orientation around the gallbladder attempted in every patient during laparoscopic cholecystectomy included B-SAFE and ultrasonographic landmarks. RESULTS The identification rate of ultrasonographic landmarks - the upper border of "Mickey Mouse" sign (MMS) (the equivalent of the Rouviere's sulcus), the bile duct, and the hepatic artery - was significantly higher in patients with body mass index ≥ 30 kg/m2 and fibrosis and chronic inflammation in the gallbladder neck than B-SAFE. LUS was also significantly more successful in the identification of the bile duct in the whole study group than B-SAFE. There were no significant differences according to the identification of the duodenum. The conversion rate was 2.6%, and we did not observe any BDI. CONCLUSIONS Visual landmarks defined in B-SAFE are not as reliable as ultrasonographic landmarks; thus, LUS should be taken into consideration in the first place as a method of navigation around the gallbladder.
