BackgroundIntussusception is common in children but rare in adults. The goal of this study was to review retrospectively the symptoms, diagnosis, and treatment of intussusception in adults.MethodsFrom 1997 to 2013, we experienced 44 patients of intussusception in patients older than 18 years. The patients were divided into enteric, ileocolic, ileocecal, and colocolonic (rectal) types. The diagnosis and treatment of these patients were reviewed.ResultsOf the 44 patients of adult intussusception, 42 were diagnosed with abdominal ultrasonography and abdominal computed tomography. There were 12 patients of enteric intussusception, six patients of ileocolic intussusception, 16 patients of ileocecal type intussusception, and 10 patients of colonic (rectal) intussusception. Among them, 77.3 % were associated with a tumor. Among 12 patients of enteric intussusception, three were associated with a metastatic intestinal tumor, and one was associated with a benign tumor. Among six patients of ileocolic intussusception, two patients were associated with malignant disease. Also, 93.8 % of ileocecal intussusceptions were associated with tumors, 80.0 % of which were malignant. Similarly, 90.0 % of colonic intussusceptions were associated with malignant tumors. Intussusception was reduced before or during surgery in 28 patients. Surgery was performed in 41 patients, and laparoscopy-assisted surgery was performed for ab underlying disease in 12 patients.ConclusionsPreoperative diagnoses were possible in almost all patients. Reduction greatly benefited any surgery required and the extent of the resection regardless of the underlying disease and surgical site.
The initial management of patients with suspected acute biliary infection starts with the measurement of vital signs to assess whether or not the situation is urgent. If the case is judged to be urgent, initial medical treatment should be started immediately including respiratory/circulatory management if required, without waiting for a definitive diagnosis. The patient's medical history is then taken; an abdominal examination is performed; blood tests, urinalysis, and diagnostic imaging are carried out; and a diagnosis is made using the diagnostic criteria for cholangitis/ cholecystitis. Once the diagnosis has been confirmed, initial medical treatment should be started immediately, severity should be assessed according to the severity grading criteria for acute cholangitis/cholecystitis, and the patient's general status should be evaluated. For mild acute cholangitis, in most cases initial treatment including antibiotics is sufficient, and most patients do not require biliary drainage. However, biliary drainage should be considered if a patient does not respond to initial treatment. For moderate acute cholangitis, early endoscopic or percutaneous transhepatic biliary drainage is indicated. If the underlying etiology requires treatment, this should be provided after the patient's general condition has improved; endoscopic sphincterotomy and subsequent choledocholithotomy may be performed together with biliary drainage. For severe acute cholangitis, appropriate respiratory/ circulatory management is required. Biliary drainage should be performed as soon as possible after the patient's general condition has been improved by initial treatment and respiratory/circulatory management.

Bile duct injury (BDI) during laparoscopic cholecystectomy remains a serious iatrogenic surgical complication. BDI most often occurs as a result of misidentification of the anatomy; however, clinical evidence on its precise mechanism and surgeons' perceptions is scarce. Surgeons from Japan, Korea, Taiwan, and the USA, etc. (n = 614) participated in a questionnaire regarding their BDI experience and near-misses; and perceptions on landmarks, intraoperative findings, and surgical techniques. Respondents voted for a Delphi process and graded each item on a fivepoint scale. The consensus was built when ≥80% of overall responses were 4 or 5. Response rates for the first-and second-round Delphi were 60.6% and 74.9%, respectively. Misidentification of local anatomy accounted for 76.2% of BDI. Final consensus was reached on: (1) Effective retraction of the gallbladder, (2) Always obtaining critical view of safety, and (3) Avoiding excessive use of electrocautery/ clipping as vital procedures; and (4) Calot's triangle area and (5) Critical view of safety as important landmarks. For (6) Impacted gallstone and (7) Severe fibrosis/ scarring in Calot's triangle, bail-out procedures may be indicated. A consensus was reached among expert surgeons on relevant landmarks and intraoperative findings and appropriate surgical techniques to avoid BDI.
Background Serious complications continue to occur in laparoscopic cholecystectomy (LC). The commonly used indicators of surgical difficulty such as the duration of surgery are insufficient because they are surgeon and institution dependent. We aimed to identify appropriate indicators of surgical difficulty during LC. Methods A total of 26 Japanese expert LC surgeons discussed using the nominal group technique (NGT) to generate a list of intraoperative findings that contribute to surgical difficulty. Thereafter, a survey was circulated to 61 experts in Japan, Korea, and Taiwan. The questionnaire addressed LC experience, surgical strategy, and perceptions of 30 intraoperative findings listed by the NGT. Results The response rate of the survey was 100%. There was a statistically significant difference among nations regarding the duration of surgery and adoption rate of safety measures and recognition of landmarks. The criteria for conversion to an open or subtotal cholecystectomy were at the discretion of each surgeon. In contrast, perceptions of the impact of 30 intraoperative findings on surgical difficulty (categorized by factors related to inflammation and additional findings of the gallbladder and other intra-abdominal factors) were consistent among surgeons. Conclusions Intraoperative findings are objective and considered to be appropriate indicators of surgical difficulty during LC.
Background We previously identified 25 intraoperative findings during laparoscopic cholecystectomy (LC) as potential indicators of surgical difficulty per nominal group technique. This study aimed to build a consensus among expert LC surgeons on the impact of each item on surgical difficulty. Methods Surgeons from Japan, Korea, and Taiwan (n = 554) participated in a Delphi process and graded the 25 items on a seven-stage scale (range, 0-6). Consensus was defined as (1) the interquartile range (IQR) of overall responses ≤2 and (2) ≥66% of the responses concentrated within a median AE 1 after stratification by workplace and LC experience level. Results Response rates for the first and the second-round Delphi were 92.6% and 90.3%, respectively. Final consensus was reached for all the 25 items. 'Diffuse scarring in the Calot's triangle area' in the 'Factors related to inflammation of the gallbladder' category had the strongest impact on surgical difficulty (median, 5; IQR, 1). Surgeons agreed that the surgical difficulty increases as more fibrotic change and scarring develop. The median point for each item was set as the difficulty score. Conclusions A Delphi consensus was reached among expert LC surgeons on the impact of intraoperative findings on surgical difficulty.
Double gallbladder is a rare congenital anomaly and an encounter with it while performing cholecystectomy laparoscopically is a challenge to the laparoscopic surgeon. A 28-year-old man complaining of epigastric pain was evaluated at Teikyo University Hospital, Mizonokuchi, Japan. There were no abnormal laboratory findings. Ultrasonography revealed an acoustic shadow in each compartment without any inflammatory changes in the gallbladder. No lesions were endoscopically noted in the stomach. CT scan could not demonstrate the anomaly. ERCP revealed a duplication of the gallbladder shadow with a stone in each vesicle and also the confluence of two cystic ducts from both the gallbladders draining into the common bile duct (CBD). Laparoscopic cholecystectomy was performed successfully in this case. This paper presents this particular case because of double gallbladder's rarity in the literature and to emphasize the importance of preoperative cholangiographic evaluation for double gallbladder. The laparoscopic surgeon is given an idea of the meticulous dissection at the "hepatocystic triangle" due to the various other vascular and other congenital anomalies associated with it. An account of the classification of this congenital abnormality and its various types is also discussed here.
Bipolar diathermy hemorrhoidectomy is quick and bloodless and, although as painful as closed hemorrhoidectomy with the ultrasonic scalpel, is associated with a reduced analgesic requirement immediately after operation.
