Major bile duct injury (BDI) rates remain in the range of 0.3 to 0.5 per cent for laparoscopic cholecystectomy (LC). The dominant surgical technique worldwide continues to be the “infundibular” technique of dissection that was popularized in the early 1990s. Proponents of the “critical view of safety” (CV) technique have suggested that most of these injuries are avoidable. The objective of our study was to determine whether routine use of the CV technique reduced the observed/expected single-institution rate of major BDI over a 5-year period in a teaching hospital. All patients (n = 3042) who underwent LC for any indication at one institution over a 60-month period were identified by database search. Major BDI was identified by Common Procedural Terminology codes indicating operative repair and confirmed by review of medical records. One patient sustained a transection–excision of the common duct requiring hepaticoduodenostomy. Based on published data, the observed BDI rate was one in nine to one in 15 of the expected rate. This represents an order-of-magnitude improvement in the safety of LC at a single institution where the majority of cases were performed by residents. We suggest that the “critical view” technique should be widely adopted.

Abstract Background Safe laparoscopic cholecystectomy(LC) depends on surgeon's experience, operative difficulty, utilisation of traditional safety markers, adapting the dissection technique and, where possible, displaying the critical view of safety (CVS) to confirm cystic pedicle structures prior to division. The Safe Cholecystectomy Multi-Society Practice Guidelines and State of the Art Consensus Conference on Prevention of Bile Duct Injury During Cholecystectomy identified no direct comparative evidence to support the CVS over other methods of anatomic identification. The aim of this study, therefore, was to examine the consistency of safety markers guiding the dissection and to determine the value of displaying the CVS. Methods A pilot study was conducted, reviewing video recordings of 241 LCs (144 retrospective and 97 prospective). The consistency of the Rouvier Sulcus (RS), the cystic lymph node (CLN), identification of the common bile duct (CBD) and duodenum and a new marker; the “cystic duct fold” (CDF), the peritoneal fold stretching between the retracted Hartman's Pouch and the CBD guiding the dissection at its distal end over the gallbladder neck, was documented. Data on the safety marker used to commence dissection, gallbladder condition, the LC difficulty grade, the selected technique and whether the CVS was achieved was recorded and analysed. Results Although the CBD and duodenum were visualised in 77%, the CDF was identifiable in 56% (CLN in 52.3%, RS in 50.2%) and the most consistently used to commence dissection in 51.4% (CLN 17.4%, CBD in 11.6% and RS in 6.6%). 12.8% required access to the infundibulum using sub-serosal or trans-vesical dissection (41% had acute cholecystitis, empyema or gangrenous gallbladders). Infundibular dissection was used in 88%. CVS was achievable in 56.8%. The CDF dropped form 87% in difficulty grades 1 and 2 to 16.5% in grades 4 and 5 with the CLN used in 21% of these difficult LCs. Conclusions A new safety marker, the CDF is proposed, being more reliable and safer on account of starting the dissection away from the CBD and potentially aberrant ducts, contrary to the line of RS. The CLN is more reliable in difficult LC, especially with acute inflammation. Infundibular dissection remains the default approach to “target identification” required to display the CVS. The true value of the CVS, as an end product of the process of dissection, lies in “target confirmation” before dividing any structures and in clearing the cystic plate to avoid injury to Couinaud Types C, F and hepato-cystic ducts.

Abstract Background The critical view of safety (CVS) method can be achieved by avoiding vasculo-biliary injury resulting from misidentification during laparoscopic cholecystectomy (LC). Although achieving the CVS has become popular worldwide, there is no established standardized technique to achieve the CVS in patients with an anomalous bile duct (ABD). We recently reported our original approach for securing the CVS using a new landmark, the diagonal line of the segment IV of the liver (D-line). The D-line is an imaginary line that lies on the right border of the hilar plate. The cystic structure can be securely isolated along the D-line without any misidentification, regardless of the existence of an ABD. We named this approach the segment IV approach in LC. Methods In this study, we adopted the segment IV approach in patients with an ABD. Results From October 2015 to June 2020, 209 patients underwent LC using the segment IV approach. Among them, three (1.4%) were preoperatively diagnosed with an ABD. The branching point of the cystic duct was the posterior sectional duct, anterior sectional duct, or left hepatic duct in each patient. The CVS was achieved in all cases without any complications. Conclusion It is a promising technique, especially even for patients with an ABD during LC.

INTRODUCTION There is debate on optimal techniques that reduce bile duct injury during laparoscopic cholecystectomy (LC). A national survey of Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland (AUGIS) members was carried out to determine current surgical practice for gallstones, including the use of intra-operative cholangiography (IOC) or critical view of safety to reduce the risk of bile duct injury. SUBJECTS AND METHODS An anonymous postal survey was sent to all 417 AUGIS members. Data on grade of surgeon, place of work (district general hospital, teaching), subspecialty, number LC per year, use of IOC, critical view of safety, and management of stones detected during surgery were collated. RESULTS There was a 36% (152/417) response – 134 (88%) from consultant surgeons (36, HPB; 106,OG; 64, DGH; 88, teaching hospital). Of these, 38% performed > 100 LC per year, 36% 50–100 LC per year, and 22% 25–50 LC per year. IOC was routine for 24%; and selective for 72%. Critical view of Calot's triangle was advocated by 82%. Overall, 55% first clip and divide the cystic artery, whereas 41% first clip and divide the cystic duct. Some 39% recommend IOC and 23% pre-oper-ative MRCP if dilated common bile duct (CBD) is noted on pre-operative ultrasound. When bile duct stones are identified on IOC, 61% perform laparoscopic CBD exploration (LCBDE), 25% advise postoperative ERCP, and 13% perform either LCBDE or ERCP. Overall, 88% (n = 134) recommend index cholecystectomy for acute pathology, and this is more likely in a teaching hospital setting (P= 0.003). Laparoscopic CBD exploration was more likely to be performed in university hospitals (P< 0.05). CONCLUSIONS A wide dissection of Calot's triangle to provide a critical view of safety is the technique most commonly recommended by AUGIS surgeons (83%) to minimise risk of bile duct injury, in contrast to 24% that recommend routine IOC. The majority (88%) of AUGIS surgeons advise index admission cholecystectomy for acute gallbladder disease.

Left-sided gallbladder (LSGB) is a rare bile duct abnormality, usually found during a cholecystectomy. Symptoms usually do not differ from those of a normally positioned gallbladder, making the preoperative diagnosis extremely uncommon. We report the case of an acute cholecystitis in a patient whit LSGB, safely managed with laparoscopic surgery. A 24-year-old male patient was admitted to our institution with clinical and radiological signs of acute cholecystitis. The intraoperative finding of an acute cholecystitis in a LSGB made us modify ports positioning and a cholangiograhy was done by direct puncture of the gallbladder before hilum dissection. After the cystic duct was identified, a transcystic cholangiography was performed which confirmed a complete and clear bile duct anatomy and laparoscopic cholecystectomy was safely completed. The intraoperative finding of a LSGB makes the surgeon change some aspects of the usual technique to perform a safe cholecystectomy as LSGB significantly increases the risk of common bile duct injuries. Meticulous dissection of the gallbladder hilum to achieve a critical view of safety and the systematic use of intraoperative cholangiography are extremely important to perform a safe laparoscopic cholecystectomy.
