The clinical effect of a strategy called transcystic gallbladder-preserving cholecystolithotomy based on endoscopic retrograde cholangiopancreatography for cholecystolithiasis: A retrospective study from a single center.

Choledocholithiasis complicated with cholecystolithiasis is a common disease. This study explores a novel strategy, called ERCP-based transcystic gallbladder-preserving cholecystolithotomy, for the simultaneous removal of common bile duct stones and gallbladder stones. From December 2018 to June 2021, all patients with cholecystolithiasis and common bile duct stones who met the criteria for gallbladder preservation in our hospital were included in the study and prospectively followed up. We included 48 patients, including 20 patients with acute biliary pancreatitis. All patients successfully underwent ERCP to remove common bile duct stones. One patient had gallbladder perforation during gallbladder-preserving cholecystolithotomy. The guide wire successfully entered the gallbladder, and the transpapillary gallbladder metal-covered stent was successfully placed in 44 patients. The technical success rate was 91.67% (44/48). All stones were removed in 34 patients, for a clinical success rate of 77.27% (34/44). The total postoperative complication rate was 6.25% (3/48), with 2 cases of pancreatitis (4.17%) and 1 case of cholangitis (2.08%). Three patients were lost to follow-up. Among the 31 patients who were followed up for a mean of 27 months (6-40), 5 patients (16.13%) experienced gallstone recurrence. The recurrence rates at 12 months, 18 months, 24 months, 30 months and 36 months were 0%, 3.23%, 6.45%, 12.9%, and 16.13%, respectively. For patients with cholecystolithiasis and common bile duct stones, ERCP-based transcystic gallbladder-preserving cholecystolithotomy without gallbladder incision can preserve gallbladder structure, and this procedure is safe and feasible for the protection of gallbladder function.Clinical trial registration: The study was registered in the Chinese Clinical Trial Registry, and the registry number is ChiCTR1900028006.

The Application of Probe-Based Confocal Laser Endomicroscopy as a Diagnostic Tool in Choledochoscopic Gallbladder-Preserving Surgery

Background and Aims: Choledochoscopic gallbladder-preserving surgery (CGPS) has the advantage of treating benign gallbladder diseases on the premise of gallbladder preservation. However, it has no reliable preoperative diagnosis if the gallbladder is benign. Probe-based confocal laser endomicroscopy (pCLE) can obtain real-time and clear endoscopic images at the cell level in vivo. It is widely used in the diagnosis of digestive system diseases, but not in gallbladder diseases yet. We applied these two technologies in a complementary way into the diagnosis of gallbladder diseases and thereby lifted the reliability of CGPS. Methods: We retrospectively analyzed the total 28 patients with the indication of CGPS with intraoperative pCLE scan referred to the Second Affiliated Hospital of Baotou Medical College between October 2019 and July 2020. The intraoperative pCLE results were compared with the postoperative pathology in various gallbladder diseases. Results: We compared the intraoperative pCLE diagnosis with the postoperative pathological diagnosis and found a complete match without exception in both sensitivity and specificity. Conclusions: Based on our investigation, pCLE can provide the same accuracy as the traditional pathology in the diagnosis of gallbladder diseases with the additional advantages like noninvasive, real time, and instancy. This study serves to validate the correlation between CLE and histology. It holds a broad prospect in the application of pCLE as an intraoperative diagnosis in CGPS.

Feasibility of gallbladder preservation during robotic left hepatectomy: A retrospective comparative study

ObjectiveTraditionally, gallbladder is routinely removed during left hepatectomy even if there is no gallbladder pathology. However, adverse consequence after cholecystectomy, though rare, still occasionally occurs. This study aims to evaluate the feasibility of gallbladder preservation during robotic left hepatectomy. MethodsAll consecutive robotic left hepatectomy cases between December 2010 and January 2022 in Prince of Wales Hospital, the Chinese University of Hong Kong were retrieved from a prospectively collected database. The gallbladder was preserved by moving the liver transection line just away from the gallbladder fossa. Patients were divided into two groups: gallbladder preservation (GBP) and non-gallbladder preservation (NGBP). Operative results and long-term outcomes were compared between these two groups. ResultsThere were 11 cases in the GBP group and 25 cases in the NGBP group. The two groups were comparable in terms of the patient demographics and disease characteristics. There was no operative mortality. There was no difference between the two groups in operative time (GBP 270 min vs. NGBP 332 min, p = 0.132), blood loss (GBP 50 mL vs. NGBP 150 mL, p = 0.115) or complication rate (GBP 27.3% vs. NGBP 24.0%, p > 0.999). There was also no difference in 5-year overall survival. In the GBP group, no patient developed specific symptoms or complications related to the preserved gallbladder. Follow-up ultrasound or computed tomography revealed a normal appearance of the preserved gallbladders except in one patient who developed a 3-mm gallbladder polyp. On the other hand, one (4%) patient in the NGBP group developed troublesome diarrhoea after surgery. ConclusionGallbladder preservation is safe and feasible during robotic left hepatectomy. The preserved gallbladder does not lead to any symptoms, while postcholecystectomy diarrhoea can be avoided.

Laparoscopic Common Bile Duct Exploration with Gallbladder Preservation: An Innovative Technique for Primary Common Bile Duct Stones.

Background: Primary common bile duct (CBD) stones can be treated with laparoscopic CBD exploration (LCBDE), during which cholecystectomy is routinely performed. For patients without gallstones, we have developed a new procedure, LCBDE with gallbladder preservation. The purpose of this study was to evaluate the management of LCBDE with gallbladder preservation at our institution. Methods: Retrospective analysis the clinical data of 105 patients with primary CBD stones. Demographic data, clinical characteristics, preoperative risk factors, and postoperative complications were evaluated. Results: All patients were divided into two groups depending on the presence of gallstones: the primary CBD stone coexistence gallstones group (Group A, n = 15) and the primary CBD stones absence gallstones group (Group B, n = 90). Complete stones clearance was achieved in all patients. There were no significant differences in postoperative complications rates and mortality between the two groups. The mean postoperative hospital stay was 3.2 days for Group A and 4.1 days for Group B (P = .03). Conclusion: This study found that LCBDE with gallbladder preservation can effectively and safely treat primary CBD stones without gallbladder stones.

Prospective study on changes in the donor gallbladder contraction function after left lateral lobe hepatectomy.

This study aimed to evaluate the feasibility of donor gallbladder preservation in liver transplantation. Conventional removal of the donor gallbladder is applied in a majority of pediatric liver transplantation. A total of 42 donors who underwent gallbladder preservation in liver transplantation from October 2013 to December 2015 at the Beijing Friendship Hospital, China, were enrolled for the study. The changes in gallbladder volume and the gallbladder EF of donors before and after surgery were measured through ultrasound, and the changes in the donor gallbladder contraction function before and after surgery were evaluated to help verify the feasibility of gallbladder preservation in living donor left lateral lobe hepatectomy. The gallbladder emptying index dropped to 42.67% in 2weeks after surgery and gradually increased with the length of recovery time, which could reach 69.14% in 3months after surgery. At that time, 97.6% of the donors were considered to have recovered their gallbladder contraction function. The gallbladder contraction function at an early stage after gallbladder preservation in liver transplantation is not obviously improved, but it can recover to a normal level in 1month after surgery, indicating that the gallbladder preservation in hepatectomy of living donor can effectively guarantee the gallbladder contraction function.

Complication Follow-up With Ultrasonographic Analyses of 91 Cases With Donor Gallbladder Preservation in Living Donor Liver Transplantation of Left Lateral Sectionectomies

BackgroundPreserving the donor's gallbladder during living donor liver transplantation (LDLT) is a better method for liver transplantation surgery, but not enough is known about gallbladder complications after the operation. MethodsWe retrospectively investigated postsurgical donor gallbladder complications in clinical LDLT with gallbladder preservation. The feasibility of retaining the gallbladder during liver graft procurement is discussed. Ninety-one donors with retained gallbladder after LDLT with the hepatic left lateral sectionectomy (from June 2013 to October 2015) were retrospectively analyzed. Donors were followed for 12.6 to 40.7 months after surgery (median 26.1 months). Sonography was used to evaluate gallbladder characteristics before and after surgery. ResultsGallbladder function had recovered to almost normal 1 month after transplantation. Four donors (4.40%) experienced gallbladder enlargement that resolved after 3 days. Thickening of the gallbladder wall in 31 donors (34.07%) was restored within 2 to 75 days. Biliary sludge appeared in 9 donors (9.89%); 6 of them recovered within 3 to 34 days. Three (3.30%) and 1 donor (1.10%) suffered gallstone and gallbladder polyps, respectively, which persisted until the last follow-up. ConclusionThe rate of postoperative complications of the gallbladder in donors was relative low. Preserving the gallbladder in liver transplantation donors during liver graft procurement is feasible and safe.

Feasibility of liver graft procurement with donor gallbladder preservation in living donor liver transplantation.

Cholecystectomy is routinely performed at most transplant centers during living donor liver transplantation (LDLT). This study was performed to evaluate the feasibility of liver graft procurement with donor gallbladder preservation in LDLT. Eighty-nine LDLTs (from June 2006 to Dec 2012) were retrospectively analyzed at our hospital. The surgical approach for liver graft procurement with donor gallbladder preservation was assessed, and the anatomy of the cystic artery, the morphology and contractibility of the preserved gallbladder, postoperative symptoms, and vascular and biliary complications were compared among donors with or without gallbladder preservation. Twenty-eight donors (15 right and 13 left-liver grafts) successfully underwent liver graft procurement with gallbladder preservation. Among the 15 right lobectomy donors, for 12 cases (80.0 %) the cystic artery originated from right hepatic artery. From the left hepatic artery and proper hepatic artery accounted for 6.7 % (1/15), respectively. Postoperative symptoms among these 28 donors were slight, although donors with cholecystectomy often complained of fatty food aversion, dyspepsia, and diarrhea during an average follow-up of 58.6 (44-78) months. The morphology and contractibility of the preserved gallbladders were comparable with normal status; the rate of contraction was 53.8 and 76.7 %, respectively, 30 and 60 min after ingestion of a fatty meal. Biliary and vascular complications among donors and recipients, irrespective of gallbladder preservation, were not significantly different. These data suggest that for donors compliant with anatomical requirements, liver graft procurement with gallbladder preservation for the donor is feasible and safe. The preserved gallbladder was assessed as functioning well and postoperative symptoms as a result of cholecystectomy were significantly reduced during long-term follow-up.

Evaluating gallbladder preservation

A new minimally invasive gallbladder-preserving operation has emerged for the treatment of gallbladder stones,but fundamentally it is a replica of the previous gallbladder preservation method.The gallbladder aids in digestion but is not essential for life.Its function should not be exaggerated and should not instigate trivial reasons for its preservation.Most patients undergoing cholecystectomy maintain a good quality of life.The causes,mechanisms,and prevention of gallstone formation remains mysterious,so a high recurrence rate after gallbladder-preserving operation is difficult to avoid.A full cholecystectomy can avoid recurrence complications and the benefits outweigh the risks.A discussion of the benefits and complications must be initiated to evaluate both treatment modalities for gallstones.

A New Strategy of Minimally Invasive Surgery for Cholecystolithiasis: Calculi Removal and Gallbladder Preservation

Background: Cholecystolithiasis is a common disease. Cholecystectomy is the main treatment method but is associated with various complications in some patients. This study explores a novel, minimally invasive surgery for the removal of calculi and the preservation of the gallbladder using a laparoscope combined with the soft choledochoscope. Method: A retrospective analysis was conducted between January 2010 and December 2012 in 65 patients with cholecystolithiasis who underwent the minimally invasive surgery for calculi removal and gallbladder preservation. Results: In 61 cases of gallstone removal, the gallbladder was preserved perfectly with no complications. The other 4 cases were switched to laparoscopic cholecystectomy because of tiny stones blocking the cystic duct or submucosal stones. The success rate was 93.8%. Follow-up included both clinical assessment and ultrasound examination every 6 months after the operation. The patients with preoperative symptoms were symptom-free, and gallbladder function was well preserved. The overall stone recurrence rate was 4.92% at a mean follow-up of 26 months (range 6-40). Conclusions: Using the laparoscope combined with the soft choledochoscope for gallbladder-preserving cholecystolithotomy can remove stones, preserve gallbladder function, and effectively avoid the various complications of cholecystectomy. In our follow-up, gallbladder function was not affected and the stone recurrence rate was quite low.

Outcome of gallbladder preservation in surgical management of primary bile duct stones.

To evaluate the methods and outcome of gallbladder preservation in surgical treatment of primary bile duct stones. Thirty-five patients with primary bile duct stones and intact gallbladders received stone extraction by two operative approaches, 23 done through the intrahepatic duct stump (RBD-IDS, the RBD-IDS group) after partial hepatectomy and 12 through the hepatic parenchyma by retrograde puncture (RBD-RP, the RBD-RP group). The gallbladders were preserved and the common bile duct (CBD) incisions were primarily closed. The patients were examined postoperatively by direct cholangiography and followed up by ultrasonography once every six months. In the RBD-IDS group, residual bile duct stones were found in three patients, which were cleared by a combination of fibrocholedochoscopic extraction and lithotripsy through the drainage tracts. The tubes were removed on postoperative day 22 (range: 16-42 days). In the RBD-RP group, one patient developed hemobilia and was cured by conservative therapy. The tubes were removed on postoperative day 8 (range: 7-11 days). Postoperative cholangiography showed that all the gallbladders were well opacified, contractile and smooth. During 54 (range: 6-120 months) months of follow-up, six patients had mildly thickened cholecystic walls without related symptoms and further changes, two underwent laparotomies because of adhesive intestinal obstruction and gastric cancer respectively, three died of cardiopulmonary diseases. No stones were found in all the preserved gallbladders. The intact gallbladders preserved after surgical extraction of primary bile duct stones will not develop gallstones. Retrograde biliary drainage is an optimal approach for gallbladder preservation.

Cholecystectomy versus cholecystolithotomy for cholelithiasis in childhood: Long-term outcome

Background/Purpose: The presence of cholelithiasis is being reported with increased frequency in childhood. Little is known about the natural history of the disease, and only a few studies have been published regarding long-term results of treated patients. Controversy still exists regarding optimal treatment. Both cholecystectomy and cholecystolithotomy with gallbladder preservation have been recommended as the preferred operative intervention. The purpose of this study was to compare the long-term outcome of cholecystectomy versus cholecystolithotomy for symptomatic gallbladder disease in children. Methods: The charts of all patients with symptomatic cholelithiasis treated in the Dublin Paediatric Hospitals during a 25-year period from 1974 till 1999 were reviewed. Data obtained included age, sex, age at presentation of symptoms, methods of diagnosis, indications for operative treatment, time interval between presentation of symptoms and surgery, surgical technique, performance of a preoperative or intraoperative cholangiogram, stone biochemistry, gallbladder histology, radiologic follow-up, the presence of recurrent or residual stones and symptoms, and the need for reoperation. Patient data were grouped according to method of surgery. All parameters were compared and evaluated. Follow-up was by way of telephone contact with all patients and completion of a questionnaire. Results: There were 18 patients over a 25-year period. Eight patients underwent cholecystectomy, and 10 patients had a cholecystolithotomy. Median follow-up was 2 years in the cholecystectomy group and 5 years in the cholecystolithotomy group. All patients in the cholecystectomy group are asymptomatic and have no recurrent or residual stones on follow-up ultrasound scan. Thirty percent of the patients in the cholecystolithotomy group have recurrent right upper quadrant pain, and 30% show recurrent stones 9.5 months (range, 7 to 12 months) postoperatively. One patient underwent cholecystectomy 8.5 months postcholecystolithotomy. Conclusions: The symptomatic high stone recurrence rate postcholecystolithotomy seen in our series suggest that cholecystectomy is the preferred treatment in patients with symptomatic gallbladder disease.
