Progress in Research on Endoscopic Ultrasonography-guided Gallbladder Drainage / 胃肠病学

Laparoscopic cholecystectomy is the gold standard for treatment of gallstones with clinical symptoms, however, various complications may occur. Endoscopic ultrasonography-guided gallbladder drainage (EUS-GBD) has the advantages of minimal invasion, keeping the gallbladder and safe in operation, which is suitable for the conservative treatment under endoscopy of patients who are intolerant to laparoscopic cholecystectomy and having strong will to keep gallbladder, and for advanced malignant tumor patients with distal bile duct obstruction. This article reviewed the progress in research on EUS-GBD.

The Benefits of Percutaneous Transhepatic Gallbladder Drainage prior to Laparoscopic Cholecystectomy for Acute Cholecystitis

PURPOSE: Several studies have reported that laparoscopic cholecystectomy with percutaneous transhepatic gallbladder drainage (PTGBD) is associated with a reduced duration of surgery and a lower rate of conversion to open laparotomy compared with laparoscopic cholecystectomy without PTGBD and delayed laparoscopic cholecystectomy after conservative therapy. However, these results are contradictory. This retrospective study investigated the safety and usefulness of laparoscopic cholecystectomy combined with pre-operative PTGBD in patients with acute cholecystitis. METHODS: The clinicopathologic data and surgical outcomes of 101 patients who underwent laparoscopic cholecystectomy between January 2010 and September 2015 were reviewed retrospectively. RESULTS: Patients in the PTGBD group vs. the non-PTGBD group were significantly older (mean age: 65.47±12.2 vs. 56.32±13.7; p=0.001). Underlying diseases were also significantly more common in the PTGBD group (75.4% vs. 45.5%; p=0.002). There were no significant differences between the two groups in terms of operative time, blood loss, rate of open conversion, postoperative oral intake, and postoperative hospital stay. Total hospital day was significantly longer in the PTGBD group (11.14±7.22 vs. 6.23±5.17; p=0.049). There was no significant difference in the postoperative complications between the two groups, and all patients in this study lived. CONCLUSION: This study suggested that satisfactory results can be achieved with selective preoperative PTGBD in older and sicker patients with acute cholecystitis.

Successful Bile Duct Cannulation Guided by Indigocarmine Injection via PTGBD / 대한소화기내시경학회지

Even though percutaneous transhepatic gallbladder drainage (PTGBD) is performed prior to ERCP or following ERCP because of the patients' medical condition or failed bile duct cannulation, there are no definite endoscopic landmarks that are useful for successful bile duct cannulation in some cases. We report here on 4 patients in whom selective bile duct cannulation, as guided by the endoscopic landmarks, was successful following indigocarmine injection via PTGBD.

Impact of PTGBD on Patients with Acute Complicated Cholecystitis: Consecutive 4,000 Cases of Laparoscopic Cholecystectomy / 대한내시경복강경외과학회지

PURPOSE: The aim of this study was to determine the advantage of adequate PTGBD in acute complicated cholecystitis patients. METHODS: We performed a retrospective review of a collected database from September 2001 to July 2008. Acute cholecystitis with gangrene or perforation was defined as acute complicated cholecystitis. A PTGBD was performed for these patients immediately after the diagnosis using US or CT and then a tubogram was performed after 5~7 days. After evaluating the gallbladder (GB) and common bile duct (CBD) with a tubogram, we removed the drainage tube and the patients underwent a LC after readmission. RESULTS: Three hundred seventy four of the 893 patients who were diagnosed with acute cholecystitis underwent PTGBD. While 19 (3.2%) of the total acute cholecystitis patients were converted to open cholecystectomy due to severe inflammation, 14 (3.7%) of the acute complicated patients were converted to open cholecystectomy. In 79 patients, the pre-operative tubogram showed the presence of CBD stone and so ERCP was performed. There were no post-operative deaths. CONCLUSION: PTBGD in acute complicated cholecystitis patients allows the early relief of acute cholecystitis symptoms. This allows sufficient evaluation and treatment for CBD during the PTGBD state. Furthermore, this decreases the mortality and morbidity in the high-risk patients due to sufficient evaluation and management of the underlying critical disease, which allows elective cholecystectomy when the patients is in better condition for surgery. Therefore, PTGBD can be useful for acute complicated cholecystitis.

Comparison of Early Versus Delayed Laparoscopic Cholecystectomy after Percutaneous Transhepatic Gallbladder Drainage (PTGBD) for Patient with Complicated Acute Cholecystitis

PURPOSE: This study was to evaluate the safety and conversion rate of laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGBD) in patients with a complicated acute cholecystitis (GB empyema, gangrenous cholecystitis and pericholecystic abscess) according to the timing of LC. METHODS: One hundred and four patients, who underwent a laparoscopic cholecystectomy after PTGBD between March 2004 and December 2006, were analyzed. Thirty-four patients underwent LC within 7 days after PTGBD (early group, n=34) and 38 patients underwent LC between 14 and 39 days after PTGBD (delayed group, n=38). Thirty-two patients were excluded because of gallbladder cancer (n=2), simple acute cholecystitis (n=12), a history of previous abdominal surgery (n=5), and LC between 8 and 13 days after PTGBD (n=13). RESULTS: There was no significant difference in age (early group, 58.4+/-11.2; delayed group, 61.0+/-12.1), diagnosis, duration of symptoms, WBC counts, interval of admission and PTGBD, improvement of symptoms after PTGBD, American Society of Anesthesiologists (ASA) score, prior medical history, post-PTGBD and postoperative complications, and operation time. The rate of conversion to an open laparotomy was 14.7% (5/34) in the early group and 2.6% (1/38) in the delayed group (statistically not significant). CONCLUSION: The timing of LC after PTGBD for a complicated acute cholecystitis does not influence the rate of conversion to an open laparotomy, surgery time and complication. However, a delayed LC after PTGBD tends to decrease the rate of conversion to an open laparotomy.

Usefulness of Preoperative Percutaneous Transhepatic GB Drainge on Laparoscopic Cholecystectomy in Patients with Acute Cholecystitis / 한국간담췌외과학회지

BACKGROUND/AIMS: A laparoscopic cholecystectomy (LC) has many clinical advantages and is now recognize as the choice of treatment for gallstones. However a laparoscopic cholecystectomy is often not feasible or is converted to the conventional open method in patients with acute cholecystitis because of inflammation around the gallbladder, adhesion, unclear anatomy, or intraoperative complications. Recent studies recommended that acute cholecystitis patients or gallbladder empyema patients undergo a percutaneous transhepatic GB drainage (PTGBD) first and a laparoscopic cholecystectomy later because PTGBD can be very helpful for improving the patient's state. METHODS: This study was carried out on 99 patients with acute cholecystitis or GB empyema who underwent a laparoscopic cholecystectomy after PTGBD at Eulji University School of Medicine from January 1996. These cases were compared with a control group of 41 patients who showed similar symptoms, ultrasonographic finding, operative finding, and pathologic results. RESULTS: There were no differences in the age and the sex distributions, the symptom duration, laboratory finding except alkaline phosphatase and leucocytosis. Among PTGBD group, a successful laparoscopic cholecystectomy was possible in 63 patients (63.6%), the other 36 patients were converted to open cholecystectomy. In control group, only 15 patients (36.6%) out of 41 underwent a successful laparoscopic cholecystectomy. This difference was statistically significant (P= 0.003). We analyze two groups about factors that can affect open conversion during laparoscopic cholecystectomy. In multivariate analysis, preoperative PTGBD and degree of wall thickening are the independent risk factors that can convert LC into open cholecystectomy. CONCLUSION: We think that a laparoscopic cholecystectomy performed some time after PTGBD to improve the patient's condition by eliminating acute inflammation or decompressing the gallbladder may be recommended for management of acute cholecystitis patients with severe clinical symptoms and ultrasonographic findings of marked gallbladder dilatation or pericholecystic fluid collection.

Two Cases of Emphysematous Cholecystitis / 대한내과학회지

Emphysematous cholecystitis is an uncommon form of acute cholecystitis characterized by the presence of gas within the wall, lumen of the gall bladder or biliary ducts. Clinically it is very similar to ordinary farm. But since the risk of perforation is five times that expected from ordinary cholecystitis, early diagnosis and appropriate surgical treatment are important. We could diagnose these cases by the simple abdomen, abdominal ultrasound and abdominal CT by the presence of air in the lumen and the wall of the gall bladder. Percutaneous trans hepatic gall bladder drainage (PTGBD) for decompression was used because poor general condition of patients and later, we could successfully perform the cholecystectomy without any complication. We presented two cases of emphysematous cholecystitis with review of the relevant literature on the subject.
