Some of the so called “exit strategy in a difficult case”.<\/p>\n <\/p>\n a) Calot’s triangle – Calot first described the boundaries as the common hepatic duct, cystic duct and inferior surface of the liver. Current teaching in medical school is the common hepatic duct, cystic duct and cystic artery.\u00a0 During a difficult cholecystectomy the most challenging part is to dissect out Calot’s triangle.\u00a0 If we are able to do this part safely, the rest of the surgery becomes relatively easier.<\/p>\n Surgical training teaches us to dissect this area as far away from the common bile duct as possible. This is quite easily done especially in the non infected gallbladder.\u00a0 Dissecting away from the common bile duct will reduce the risk of bile duct injuries (a serious complication of gallbladder surgery).\u00a0 However, when dealing with a necrotic or gangrenous gallbladder, the tissue around this area is often very friable or with gross inflammation caused by the infection.\u00a0 Dissecting through infected and inflamed tissue often causes lots of bleeding and the view is obscured.<\/p>\n One method which I use to overcome this is to dissect slightly closer to the common bile duct.\u00a0 The theory behind this technique is that the inflammation is caused by the infected gallbladder.\u00a0 When we are closer to the common bile duct and further away from the gallbladder, the tissue should have slightly less inflammation.\u00a0 Sometimes, I would encounter a “friendly” oedematous tissue that allow me to display the anatomy nicely.<\/p>\n b) What to do when we cannot display Calot’s triangle<\/p>\n Fundus first cholecystectomy is a technique which can be attempted in such cases.\u00a0 Fundus first cholecystectomy is not a new technique at all.\u00a0 In the open era of cholecystectomy, I have seen surgeons apply this technique routinely for all their cases.\u00a0 Current surgical teaching is not to use this technique as the first line approach because it does increase the risk of common bile duct injury.<\/p>\n The difficulty with this technique is how to identify the transition from gallbladder to cystic duct (especially in a infected gallbladder).\u00a0 One observation which I think is helpful is looking at the gallbladder fossa.<\/p>\n When dissecting the gallbladder off the liver, the gallbladder fossa will narrow down. When this narrowing is seen, I will dissect very close to the gallbladder.\u00a0 This will be the start of the gallbladder cystic duct junction.<\/p>\n c) Dissecting the gallbladder off the liver<\/p>\n In the western world, the teaching is generally to remove the whole gallbladder off the liver.\u00a0 I was taught to perform a subtotal (leaving the back wall of the gallbladder behind) cholecystectomy only during difficult cases.\u00a0 So the question is, what is a difficult case?<\/p>\n I studied and train in Australia. During my training days, I rarely encounter cirrhotic livers. This is more common in Asia because of the higher incidence of hepatitis B.\u00a0 During gallbladder surgery especially the infected ones, bleeding can be a problem.\u00a0 This is especially true in patients with liver cirrhosis.\u00a0 When dissecting an infected gallbladder off the liver, occasionally we may dissect into the liver parenchyma. This may result in bleeding which may be difficult to control.\u00a0 During my time in Singapore and various parts of Asia, I noticed that surgeons have a lower threshold of leaving the back wall of the gallbladder behind.\u00a0 Leaving the back wall behind reduces the risk of bleeding from the liver especially in cirrhotic livers.<\/p>\n d) Managing the cystic duct.<\/p>\n An important part of a gallbladder operation is closing the cystic duct.\u00a0 If the cystic duct is not closed properly, then bile will leak from the cystic stump.\u00a0 This complication can be a major problem especially if it is not identified early and managed well.<\/p>\n In cases where the cystic duct is of normal size, I would use hemalok clips to secure it.\u00a0 In the event when the cystic duct is thick and swollen, I will consider using a tie or an endoloop to close the cystic duct.\u00a0 When I am not able to get around the cystic duct or Hartmann’s pouch in badly infected cases, I would close cystic duct by suturing.<\/p>\n Last but not least, the surgeon has to ensure that here is no residual stones left in the remaining cystic duct. There are various techniques to manage this which is beyond the scope of this blog.<\/p>\n <\/p>\n The techniques mentioned above are routinely used in my laparoscopic cholecystectomy cases.\u00a0 These techniques can easily be applied to the traditional open cholecystectomy as well.<\/p>\n \nShare this blog via:<\/p>","protected":false},"excerpt":{"rendered":" 28th October 2023 https:\/\/youtu.be\/wVLgoqqkNng?si=JiGev_8W_m01EjAN The terminology used in this segment will be medically focused (aka more surgical terms).\u00a0 This segment will share some of my personal experience and techniques which I have used in the past.
