Laparoscopic management of remnant gall bladder with stones: Lessons from a tertiary care centre's experience

Objective:Laparoscopic cholecystectomy is currently the gold standard for treating symptomatic gallstone disease.Despite its success,approximately 10%of patients may experience persistent biliary symptoms,leading to the post-cholecystectomy syndrome.A remnant gallbladder with cystic duct or bile duct stones is one of the causes of this syndrome.The objective of this study was to shed light on the clinical manifestations,evaluation,therapeutic strategies,and outcomes associated with laparoscopic management of symptomatic remnant gallbladders.Methods:This was a retrospective study,conducted over a five-year period(January 2017 to December 2022)at Apollo Hospitals in South India.All patients who underwent laparoscopic completion cholecystectomy for a remnant gall bladder were included.The following data were collected:patient demographics,symptoms,preoperative investigations,intraoperative details and post operative outcomes.Results:In total,36 patients were included and analysed.The majority of patients were male(25,69.4%),with a mean age of 50.7±12.1 years.The most common presentation was pain in the upper abdomen or right upper quadrant region(24,66.7%).The laparoscopic approach was attempted in all patients,with a success rate of 94.4%.Two patients required conversion to open surgery.Cholecystoenteric fistula to the colon was observed in one patient.Choledocholithiasis was observed in 7 patients(19.4%),and stone clearance was successfully achieved using endoscopic retrograde cholangiopancreatography in all patients preoperatively.Conclusion:Incomplete gall bladder removal either intentionally or unintentionally leaves a remnant gall bladder that is at risk for stone formation and infection.Patients who have this clinical entity with symptoms require a redo or complete cholecystectomy,a complex procedure associated with certain risks.This study highlights the feasibility and safety of laparoscopic completion cholecystectomy for the management of remnant gallbladder with cystic duct or bile duct stones.

Evolutionary timescale of chalcidoid wasps inferred from over one hundred mitochondrial genomes

Chalcidoidea is one of the most biologically diverse groups among Hymenoptera.Members are characterized by extraordinary parasitic lifestyles and extensive host ranges,among which several species attack plants or serve as pollinators.However,higher-level chalcidoid relationships remain controversial.Here,we performed mitochondrial phylogenomic analyses for major clades(18out of 25 families)of Chalcidoidea based on 139 mitochondrial genomes.The compositional heterogeneity and conflicting backbone relationships in Chalcidoidea were assessed using various datasets and tree inferences.Our phylogenetic results supported the monophyly of 16families and polyphyly of Aphelinidae and Pteromalidae.Our preferred topology recovered the relationship(Mymaridae+(Signiphoridae+Leucospidae)+(Chalcididae+((Perilampidae+Eucharitidae)+remaining Chalcidoidea))).The monophyly of Agaonidae and Sycophaginae was rejected,while the gall-associated((Megastigmidae+Ormyridae)+(Ormocerinae+Eurytomidae))relationship was supported in most results.A six-gene inversion may be a synapomorphy for most families,whereas other derived gene orders may introduce confusion in phylogenetic signals at deeper nodes.Dating estimates suggested that Chalcidoidea arose near the Jurassic/Cretaceous boundary and that two dynamic shifts in diversification occurred during the evolution of Chalcidoidea.We hypothesized that the potential codiversification between chalcidoids and their hosts may be crucial for accelerating the diversification of Chalcidoidea.Ancestral state reconstruction analyses supported the hypothesis that gallinducers were mainly derived from parasitoids of gallinducers,while other gall-inducers were derived from phytophagous groups.Taken together,these findings advance our understanding of mitochondrial genome evolution in the major interfamilial phylogeny of Chalcidoidea.

Identification of genes associated with gall bladder cell carcinogenesis:Implications in targeted therapy of gall bladder cancer

Gall bladder cancer(GBC)is becoming a very devastating form of hepatobiliary cancer in India.Every year new cases of GBC are quite high in India.Despite recent advanced multimodality treatment options,the survival of GBC patients is very low.If the disease is diagnosed at the advanced stage(with local nodal metastasis or distant metastasis)or surgical resection is inoperable,the prognosis of those patients is very poor.So,perspectives of targeted therapy are being taken.Targeted therapy includes hormone therapy,proteasome inhibitors,signal transduction and apoptosis inhibitors,angiogenesis inhibitors,and immunotherapeutic agents.One such signal transduction inhibitor is the specific short interfering RNA(siRNA)or short hairpin RNA(shRNA).For developing siRNAmediated therapy shRNA,although several preclinical studies to evaluate the efficacy of these key molecules have been performed using gall bladder cells,many more clinical trials are required.To date,many such genes have been identified.This review will discuss the recently identified genes associated with GBC and those that have implications in its treatment by siRNA or shRNA.

Isolated traumatic gallbladder injury: A case report

BACKGROUND Isolated gallbladder injury(GI)(IGI)directly induced by abdominal trauma is rare.Symptoms,indications,and imaging examinations of IGI are frequently non-specific,posing tremendous diagnostic challenges,which are simple to overlook and may have severe implications.Improving doctors'understanding of gallbladder injury(GI)facilitates early detection and decreases the likelihood of severe consequences,including death.CASE SUMMARY We report a case of IGI caused by blunt violence(after falling from three meters with the umbilicus as the stress point)and performed laparoscopic repair of the gallbladder rupture,which helps clinicians understand IGI and reduce the severe consequences of delayed diagnosis.Through extensive medical history and dynamic abdominal ultrasound evaluation,doctors can identify GI early and begin surgery,thereby decreasing the devastating repercussions of delayed diagnosis.CONCLUSION This article aims to improve clinicians'understanding of IGI and propose a method for the diagnosis and treatment of GI.

Isolation and Preliminary Identification of Antibacterial Active Substances of Antagonistic Actinomycetes against Peach Crown Gall(Agrobacterium tumefaciens)

[ Objective ] The paper was to isolate and preliminarily identify the antibacterial active substances of antagonistic actinomyeete strain G19 obtained from the soil highly affected by peach crown gall （Agrobacterium tumefaciens）. [ Method] The antibacterial substances of antagonistic actinomycete strain G19 were ex- tracted using protein precipitation method, then isolated and purified using high performance liquid chromatography and medium-pressure preparative chromatogra- phy. Its molecular weight was determined by MALDI-TOFMS method, and the related functional groups were verified through chemical color reaction. [ Result] Seven peptide portions were produced from the antibacterial substances of antagonistic actinomycete strain G19 with the molecular weights of 900 - 1 300 Da after isolation and purification. It could be also inferred that it contained Cys, and carried with H2O and Na＋. Color reaction of functional groups verified that the sub- stance was polypeptide containing glycosyl. [ Conclusion] The result provided basis for the final definition of the structure of antibacterial substances in antagonistic actinomycete strain G19.

One-step palliative treatment method for obstructive jaundice caused by unresectable malignancies by percutaneous transhepatic insertion of an expandable metallic stent

AIM： To describe a simple one-step method involving percutaneous transhepatic insertion of an expandable metal stent （EMS） used in the treatment of obstructive jaundice caused by unresectable malignancies. METHODS： Fourteen patients diagnosed with obstructive jaundice due to unresectable malignancies were included in the study. The malignancies in these patients were a result of very advanced carcinoma or old age. Percutaneous transhepatic cholangiography was performed under ultrasonographic guidance. After a catheter with an inner metallic guide was advanced into the duodenum, an EMS was placed in the common bile duct, between a point 1 cm beyond the papilla of Vater and the entrance to the hepatic hilum. In cases where it was difficult to span the distance using just a single EMS, an additional stent was positioned. A drainage catheter was left in place to act as a hemostat. The catheter was removed after resolution of cholestasis and stent patency was confirmed 2 or 3 d post-procedure. RESULTS： One-step insertion of the EMS was achieved in all patients with a procedure mean time of 24.4 min. Out of the patients who required 2 EMS, 4 needed a procedure time exceeding 30 min. The mean time for removal of the catheter post-procedure was 2.3 d. All patients died of malignancy with a mean follow-up time of 7.8 mo. No stent-related complication or stent obstruction was encountered. CONCLUSIONS： One-step percutaneous transhepaticinsertion of EMS is a simple procedure for resolving biliary obstruction and can effectively improve the patient＇s quality of life.

Surgical outcome of carcinosarcoma of the gall bladder:A review

Carcinosarcoma,which comprises less than one percent of all gall bladder neoplasms,is characterized by the presence of variable proportions of carcinomatous and sarcomatous elements.Recently,several reports have described patients suffering from carcinosarcoma of the gall bladder.However,there are no large studies regarding the clinicopathologic features,therapeutic management,and surgical outcome of this disease because the number of patients who undergo resection of gall bladder carcinosarcoma at a single institution is limited.A Medline search was performed using the keywords 'gall bladder' and 'carcinosarcoma'.Additional articles were obtained from references within the papers identified by the Medline search.Optimal adjuvant chemotherapy and/or radiotherapy protocols for carcinosarcoma of the gall bladder have not been established.Curative surgical resection offers the only chance for long-term survival from this disease.The outcome of 36 patients who underwent surgical resection for carcinosarcoma of the gall bladder was poor;the 3-year overall survival rate was only 31.0% and the median survival time was 7.0 mo.Since the postoperative prognosis of carcinosarcoma of the gall bladder is worse than that of adenocarcinoma,new adjuvant chemotherapies and/or radiation techniques are essential for improvement of surgical outcome.

Endoscopic management of acute cholangitis in elderly patients

AIM: To evaluate clinical presentation, etiology, compli-cations and response to treatment in elderly patients with acute cholangitis.METHODS: Demographics, etiology of biliary obstruc-tion, clinical features, complications and associated systemic diseases of 175 patients with acute cholangitis were recorded. Endoscopic biliary drainage was performed using nasobiliary drain or stent. The complications related to ERCP, success of biliary drainage, morbidity, mortality and length of hospital stay were evaluated. RESULTS: Of 175 patients, 52 aged ≥ 60 years (groupⅠ, age < 60 years; group Ⅱ, age ≥ 60 years) and 105 were men. Fever was present in 38 of 52 patients of group Ⅱ compared to 120 of 123 in groupⅠ. High fever (fever ≥ 38.0℃) was more common in groupⅠ(118/120 vs 18/38). Hypotension (5/123 vs 13/52), altered sensorium (3/123 vs 19/52), peritonism (22/123 vs 14/52), renal failure (5/123 vs 14/52) and associated comorbid diseases (4/123 vs 21/52) were more common in group Ⅱ. Biliopancreatic malignancy was a common cause of biliary obstruction in group Ⅱ (n = 34) and benign diseases in groupⅠ(n = 120). Indications for biliary drainage were any one of the following either singly or in combination: a fever of ≥ 38.0℃ (n = 136), hypotension (n = 18), peritonism (n = 36), altered sensorium (n = 22), and failure to improve within 72 h of conservative management (n = 22). High grade fever was more common indication of biliary drainage in groupⅠand hypotension, altered sensorium, peritonism and failure to improve within 72 h of conservative management were more common indications in group Ⅱ. Endoscopic biliary drainage was achieved in 172 patients (nasobiliary drain: 56 groupⅠ, 24 group Ⅱ, stent: 64 groupⅠ, 28 group Ⅱ) without any significant age related difference in the success rate. Abdominalpain, fever, jaundice, hypotension, altered sensorium, peritonism and renal failure improved after median time of 5 d in 120 patients in groupⅠ(2-15 d) compared to 10 d in 47 patients of group Ⅱ (3-20 d). Normalization of leucocyte count was seen after a median time of 7 d (3-20 d) in 120 patients in groupⅠcompared to 15 d (5-26 d) in 47 patients in group Ⅱ. There were no ERCP related complications in either group. Five patients (carcinoma gallbladder n = 3, CBD stones n = 2) died in group Ⅱ and they had undergone biliary drainage after failure of response to conservative management for 72 h. There was a higher mortality in patients in group Ⅱ despite successful biliary drainage (0/120 vs 5 /52). Length of hospital stay was longer in group Ⅱ patients (16.4 ± 5.6, 7-30 d) than in groupⅠpatients (8.2 ± 2.4, 7-20 d).CONCLUSION: Elderly patients with acute cholangitis have a high incidence of severe cholangitis, concomitant medical illnesses, hypotension, altered sensorium, peritonism, renal failure and higher mortality even after successful biliary drainage.

Outcome of gall bladder polypoidal lesions detected by transabdominal ultrasound scanning: A nine year experience

AIM: To determine the outcome of polypoidal lesions within the gall bladder (PLG) diagnosed by trans-abdominal scanning.METHODS: A nine-year (1993-2002) retrospective casenote review of all patients who underwent ultrasound scanning after referral to a single Upper GI Surgeon at a District General Hospital was conducted. Patients who were diagnosed with a PLG were included in our study. A database was constructed and patient details, investigations including ultrasound scan (USS) findings, treatment and histology and final diagnosis were recorded. RESULTS: Twenty-three (out of 651) patients were diagnosed pre-operatively by USS to have a polyp-likegall bladder lesion (PLG). Post cholecystectomy histological examination revealed 12 gallstones, 7 cholesterol polyps, 3 adenocarcinomas within polyps and 1 normal gall bladder. The specificity of USS in the diagnosis of PLG was 92.3%. All the true polyps were malignant. Overall USS had 66.66% sensitivity and 100% specificity in the pre-operative suspicion of malignancy. Using size greater than 10 mm as measured on USS as a cut-off, we find 100% sensitivity and 86.95% specificity with a positive predictive value of 50% in the diagnosis of malignancy in PLG.CONCLUSION: A large number of PLG are in fact calculi within diseased gall bladder. In cases of gall bladder polyps more then 10 mm in size on USS further imaging (crosssectional and/or EUS) is indicated prior to surgery. This will help in the optimal management of patients and avoid histological surprises.
