Moynihan's hump of the right hepatic artery in Calot's triangle: a systematic review and meta-analysis of its incidence and surgical importance. Surg Radiol Anat 2023; 45:643-651. [PMID: 36932210 DOI: 10.1007/s00276-023-03125-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 03/05/2023] [Indexed: 03/19/2023]
Abstract
INTRODUCTION A rare variation known as "Moynihan's or caterpillar hump" of the right hepatic artery raises the danger of vascular and biliary injuries during hepatobiliary surgery. This research intends to carefully record every case (i.e., patients undergoing laparoscopic cholecystectomy or cadaver dissections) where the right hepatic artery received a caterpillar hump. METHODS The literature search was conducted with the medical subject headings (MeSH) and EMTREE (subject headings unique to Embase) keywords. The keywords with Boolean operators (OR, AND, and NOT) were used to create search strings in all possible combinations to retrieve bibliographic data. Two authors independently performed a risk of bias assessment and data extraction. The random effects model was used to conduct a meta-analysis. RESULTS Thirty studies with a total of 8418 subjects reported that Moynihan's hump was present in 3.81% of them, with a predictive interval of 0.88-16.45%. The incidence of the hump was 3.1% in surgical studies (7496 subjects) and 7.22% (95% CI 4.7-10.93%) in cadaveric data (625 cadavers). Only ten studies addressed the relationship between the caterpillar hump and the common bile duct. CONCLUSION A patient with an unusually "small cystic artery" or "large right hepatic artery" is likely to have a "caterpillar hump". The caterpillar's hump of the right hepatic artery is subject to rare anatomical variations in its course that increase the risk of incorrect vessel ligation or injury during laparoscopic cholecystectomy.

Abstract
In laparoscopic cholecystectomy (LC), the treatment of iatrogenic biliary tract injury has been given much attention. However, most accidental right hepatic artery (RHA) injuries are treated with simple clipping. The reason is that the RHA has difficulty in revascularization, and it is generally considered that RHA injury does not cause serious consequences. However, some studies suggest that some cases of RHA ligation can cause a series of pathological changes correlated to arterial ischemia, such as liver abscess, bile tumor, liver atrophy and anastomotic stenosis. Theoretically, RHA blood flow should be restored when possible, in order to avoid the complications of right hepatic ischemia. The present study involved two patients, including one male and one female patient. Both patients were admitted to the hospital with the diagnosis of chronic cholecystitis and gallbladder stone, and developed ischemia of the right half hepatic after accidental transection of the RHA. Both patients underwent continuous end-end anastomosis of the RHA with 6-0 Prolene suture. After the blood vessel anastomosis, the right half liver quickly recovered to its original bright red. No adverse complications were observed in follow-ups at three and six months after the operation. Laparoscopic repair of the RHA is technically feasible. Reconstruction of the RHA can prevent complications associated with right hepatic ischemia.

Abstract
As ovarian cancer commonly involves the visceral organs without boundary, more aggressive procedures are adopted during cytoreductive surgery. One of the most difficult aspect of the operation involves the procedure for the gall bladder, porta hepatis, and omental bursa. As the upper abdominal surgical field is not familiar to the gynecologic surgeon, and the vital organs or vessels are densely positioned, these procedures can be challenging for achieving the optimal cytoreductive surgery. The surgical approaches for advanced ovarian cancer that are required in the upper abdomen have evolved with the progress in surgical techniques. This article will discuss the surgical approach by focusing on cholecystectomy, porta hepatis debulking, and omental bursectomy, as well as the regional anatomy in patients with advanced ovarian cancer.

Abstract
Objective: Incidence of Bile Duct Injuries (BDI) during Laparoscopic Cholecystectomy (LC) is reported to be higher as compared to Open Cholecystectomy. Studies have shown varying degree of success in reducing BDI by using Critical View of Safety (CVS) technique before clipping and cutting any structure. In this study, we will see whether CVS technique is faster and safer compared to conventional infundibular technique. Methods: This comparative study was conducted on patients who presented to Surgical Out-Patient-Department (OPD) of Khyber Teaching Hospital from July 2015 to June 2016. Total of 438 patients were divided into two groups. Group-A in which LC was done using infundibular while in Group-B, CVS technique was utilized. Two groups were compared for operating time and BDI. Results: The operative time was significantly reduced for LC using CVS technique (50 mins vs. 73 mins). Minor leaks were comparable (0.5% vs. 0.9%) but there was a significant difference in major LEAKS between the two techniques (0.5% vs. 1.4%). Conclusion: Although the “critical view of safety” requires more dissection as compared to infundibular technique, but once learnt and mastered, it is faster and safer identification technique during laparoscopic cholecystectomy.

Abstract
An expert recommendation conference was conducted to identify factors associated with adverse events during laparoscopic cholecystectomy (LC) with the goal of deriving expert recommendations for the reduction of biliary and vascular injury. Nineteen hepato-pancreato-biliary (HPB) surgeons from high-volume surgery centers in six countries comprised the Research Institute Against Cancer of the Digestive System (IRCAD) Recommendations Group. Systematic search of PubMed, Cochrane, and Embase was conducted. Using nominal group technique, structured group meetings were held to identify key items for safer LC. Consensus was achieved when 80% of respondents ranked an item as 1 or 2 (Likert scale 1-4). Seventy-one IRCAD HPB course participants assessed the expert recommendations which were compared to responses of 37 general surgery course participants. The IRCAD recommendations were structured in seven statements. The key topics included exposure of the operative field, appropriate use of energy device and establishment of the critical view of safety (CVS), systematic preoperative imaging, cholangiogram and alternative techniques, role of partial and dome-down (fundus-first) cholecystectomy. Highest consensus was achieved on the importance of the CVS as well as dome-down technique and partial cholecystectomy as alternative techniques. The put forward IRCAD recommendations may help to promote safe surgical practice of LC and initiate specific training to avoid adverse events.

Abstract
PURPOSE To compare the difference of primary suture following 3-port laparoscopic common bile duct exploration (LCBDE) between modified transcystic and transcholedochal approach in the treatment of choledocholithiasis. MATERIALS AND METHODS Patients who underwent 3-port LCBDE by modified transcystic approach (n = 80) and those who underwent 3-port LCBDE by transcholedochal approach (n = 209) were included in this study. The operative time, duration of hospital stay, diameter of the cystic duct, diameter of the common bile duct (CBD), complications, and demographics were retrospectively analyzed in all patients. RESULTS All operations were successfully performed. No patient was converted to laparotomy. No mortality was associated with the 2 groups. There was no significant difference between the 2 groups for the operative time (91.94 ± 34.21 min vs. 96.13 ± 32.15 min), duration of hospital stay (9.82 ± 3.48 d vs. 10.74 ± 5.34 d), diameter of cystic duct (0.47 ± 0.09 cm vs. 0.47 ± 0.08 cm), and complications (2.5% vs. 2.87%) (all P > 0.05). A significant difference was observed in terms of the diameter of CBD (1.18 ± 0.29 cm vs. 1.04 ± 0.24 cm P < 0.05). CONCLUSIONS The modified transcystic LCBDE was safe and feasible for treating choledocholithiasis but it might be more suitable for the CBD with a smaller diameter.

Abstract
INTRODUCTION Although laparoscopy has now become the procedure of choice for removal of gallbladder, complications especially injury to cystic artery and ducts are thought to be higher. We describe a technique that avoids handling and injury of cystic artery and resultant duct injuries. The video length is 2 minutes 13 seconds. MATERIALS AND METHODS From October 7, 2005, to December 31, 2010, 17 patients were successfully operated by the cystic artery sparing technique. In this technique, dissection begins distal to cystic lymph node on the gallbladder wall using hook cautery, thereby clears the Calot's triangle without even touching the cystic artery. This maneuver eliminates the risk of injuring thus causing bleeding and any subsequent complications. Age, sex, and operative outcomes including follow-ups were evaluated. RESULTS Age of the patients ranged from 3.4 years to 16 years with an average of 10.12 years. Males were predominant (10:7). Average operative time was 40 minutes. There were no intraoperative or immediate postoperative complications. Patients were allowed feeding 4-6 hours after operation and discharged the following morning. Patients were asked to come for follow-up at 1 week, 1 month, 3 months, 6 months, and 1 year and thereafter yearly. Follow-up period ranged from 6 months to 5 years. There were no operation-related complications other than minor abdominal pain in 3 patients and port-site pain in 2 patients which resolved on conservative treatments. CONCLUSION During laparoscopic cholecystectomy, if handling of the main cystic artery is avoided then complications of hemorrhage and bile duct injuries can be minimized.

Abstract
BACKGROUND AND OBJECTIVES Laparoscopic cholecystectomy has a 0.3% to 0.5% morbidity rate due to major biliary injuries. The majority of surgeons have routinely performed the so-called "infundibular" technique for gallbladder hilar dissection since the introduction of laparoscopy in the early nineties. The "critical view of safety" approach has only been recently discussed in controlled studies. It is characterized by a blunt dissection of the upper part of Calot's space, which does not usually contain arterial or biliary anomalies and is therefore ideal for a safe dissection, even in less experienced hands. MATERIALS AND METHODS We applied and compared the critical view of safety triangle approach with the infundibular approach in a retrospective cohort study. We divided 174 patients into 2 groups, with a similar case-mix (cholelithiasis, chronic cholecystitis, and acute cholecystitis). Results of operations performed by a young surgeon using critical view of safety dissection were compared to results of the infundibular approach performed by an experienced surgeon. Outcome values and operative times were examined with univariate analysis (Student t test). RESULTS No difference occurred in terms of morbidity (even though comparison for biliary injuries is inconclusive because of insufficient power) and outcome; significant differences were found in operative time, favoring the critical view of safety approach in every stage of gallbladder disease, with minor significance for acute cases. CONCLUSION We suggest this technique as the gold standard for resident teaching, because it has a similar rate of biliary and hemorrhagic complications but has a shorter operative time, builds self-confidence, and is a simple standardized method both for complicated and uncomplicated gallbladder lithiasis.
