Management of endoscopic retrograde cholangiopancreatography-related perforations

Purpose The purpose of this study is to analyze the treatment strategies of patients with endoscopic retrograde cholangiopancreatography (ERCP)-related perforations. This is a retrospective study. Methods We experienced 13 perforations associated with ERCP. We reviewed the medical recordsand classified ERCP-related perforations according to mechanism of injury in terms of perforating device. Injury by endoscopic tip or insertion tube was classified as type I, injury by cannulation catheter or sphincterotomy knife as type II, and injury by guidewire as type III. Results Of four type I injuries, one case was managed by conservative management after primary closure with a hemoclip during ERCP. The other three patients underwent surgical treatments such as primary closure orpancreatico-duodenectomy. Of five type II injuries, two patients underwent conservative management and the other three cases were managed by surgical treatment such as duodenojejunostomy, duodenal diverticulization and pancreatico-duodenectomy. Of four type III injuries, three patients were managed conservatively and the remaining patient was managed by T-tube choledochostomy. Conclusion Type I injuries require immediate surgical management after EPCP or immediate endoscopic closure during ERCP whenever possible. Type II injuries require surgical or conservative treatment according to intra- and retro-peritoneal dirty fluid collection findings following radiologic evaluation. Type III injuries almost always improve after conservative treatment with endoscopic nasobilliary drainage.

Percutaneous Transhepatic Gallbladder Drainage Changes Emergency Laparoscopic Cholecystectomy to an Elective Operation in Patients with Acute Cholecystitis

Many surgeons have found it difficult to decide whether to apply percutaneous transhepatic gallbladder drainage (PTGBD) in patients with acute cholecystitis that is not responsive to initial medical management (IMMx), because the indications of PTGBD are ambiguous. The aim of this study was to evaluate the appropriate treatment for acute cholecystitis that is not responsive to IMMx. Specifically, we focused on differences in surgical outcomes between elective and emergency laparoscopic surgeries. Between March 2006 and February 2009, 738 patients with acute cholecystitis who had undergone laparoscopic cholecystectomy (LC) at our institution were retrospectively studied. We divided them into 3 groups. Group I included 494 patients who underwent elective LC without pre-operative PTGBD, group II included 97 patients who intended to undergo elective LC after preoperative PTGBD, and group III included 147 patients who underwent emergency LC without preoperative PTGBD. We compared age, sex, symptom duration, body temperature, leukocyte counts, and American Society of Anesthesiologists (ASA) class on admission as clinical characteristics. We compared the time interval from symptom development and admission to surgery, operative time, the conversion rate to open surgery, postoperative complications, the total length of stay, and the postoperative length of stay as perioperative surgical outcomes. For patients with ASA 2 and 3, the conversion rate to open surgery in group II was significantly less than that in group III (P<.05, P<.01, respectively). We recommend PTGBD as the first choice for acute cholecystitis in patients who show no improvement after IMMx, to allow the patient to undergo an elective LC rather than emergency surgery for patients with ASA 2 and 3.

Laparoscopic treatment for post-cholecystectomy Mirizzi syndrome.

The remnant cystic duct or gallbladder neck calculus may rarely result in post-cholecystectomy Mirizzi syndrome. Various managements have been proposed for the treatment of post-cholecystectomy Mirizzi syndrome. Some previous cases of post-cholecystectomy Mirizzi syndrome have been managed with open cholecystectomy and endoscopically. We report a case of a laparoscopic stone removal of post-cholecystectomy Mirizzi syndrome that developed 7 months after laparoscopic cholecystectomy. To our knowledge, this is the first case of laparoscopic management of post-cholecystectomy Mirizzi syndrome. The mechanism, diagnosis and treatment of post-cholecystectomy Mirizzi syndrome are discussed.

Variation or newly identified glissonian pedicles between the lateral and medial sections of the liver, using cadaver dissection

Purpose Studies of liver anatomy have developed alongside clinical achievements, as these types of research complement each other. The aim of this study is to determine whether or not the portal vein branches (P4d) in Naginos trisectionectomy exist, and to examine their characteristics using cadaver dissection. Methods From April 2012 to July 2012, 31 adult cadavers were delicately dissected. We defined a NewGP as an extra glissonian pedicle (GP) other than the traditional GPs that supply segments II, III, IVa, and IVb in the ordinary direction, and anatomically located superior to the umbilical fissure (UF). Results We identified NewGPs based on the UF and UF vein. The incidence of NewGPs was 30/31 (96.8%). The diameter of the NewGPs ranged from 3.5 to 5.6 mm, which was not significantly different from that of traditional GPs (II-, III-, or IV-GP), which have diameters ranging from 3.7 to 9.7 mm. Conclusion We think that the P4d in Naginos trisectionectomy correspond to the IVa NewGP and the additional pedicle. We believe the clinical significance of the NewGP is to complement the traditional II, III, IVa, and IVb pedicles in supplying the liver.

Totally Laparoscopic Left Hemihepatectomy Using Ventral Hilum Exposure (VHE) for Intrahepatic Bile Duct Stone

The unique technique of ventral hilum exposure (VHE) was reported that it had excellent surgical outcomes in patients with intrahepatic bile duct stone. The basis of this surgical technique is that all the openings of the 2nd-order bile duct branches are exposed fully. In this article, we describe laparoscopic hemihepatectomy from using the VHE method in a patient with intrahepatic bile duct stone. Our patient was a 70-year-old female who had been diagnosed with an intrahepatic duct stone 30 years prior. Multiple intrahepatic bile duct stones in the left lateral section of the liver were revealed by abdominal computed tomography and magnetic resonance cholangiopancreatography. The patient resumed her oral intake on postoperative day 6. The patient had hyperbilirubinemia (10.3 mg/100 mL) on postoperative day 10. However, her serum bilirubin level decreased to 2.7 mg/100 mL on postoperative day 28. She was discharged without any serious complications on postoperative day 31. Totally laparoscopic left hemihepatectomy, using the VHE method, can be one option of surgical procedure in the near future, although a larger series of cases should be necessary to prove the feasibility of laparoscopic VHE.
