Purpose: The purpose of this study is to investigate the incidence of acalculous cholecystitis after multiple trauma with fractures and to analyze the characteristics of cholecystitis. Methods: We performed a retrospective study of multiple trauma patients with fractures between April 2010 and April 2012. Sixty- nine patients were identified, and the average age was 46.8(range: 15-74) years. Data were collected regarding associated injury, injury severity score (ISS), the diagnosis time after trauma, diagnostic tool, and management Results: There were three cases(4.3%) of cholecystitis among the 69 cases, and cholecystitis was diagnosed an average of 20.7(range: 8-33) days after injury. Two patients complained of abdominal pain at diagnosis, but the other patient who had undergone surgery for small bowel perforation at the time of the injury had no abdominal pain. All three patients had abnormal liver function tests (LFTs) at diagnosis. The cholecystitis was confirmed with ultrasonography or computed tomography, and all cases were acalculous cholecystitis. At first, percutaneous transhepatic gallbladder drainage was performed; then, laparoscopic cholecystectomy (LC) was tried an average of 12(range: 11-13) days later. An laparoscopic cholecystectomy was successfully done in only one case, the other cases being converted to an open cholecystectomy due to severe inflammation. Conclusion: The incidence of acaculous cholecystitis was 4.3% after multiple trauma with fractures. We should consider cholecystitis in patients with abdominal pain, fever and elevated LFTs after multiple trauma.

Gallbladder (GB) polyp is a mucosal projection into the GB lumen. With increasing health awareness, GB polyps are frequently found using ultrasonography during health screening. The prevalence of GB polyps ranges between 1.3% and 9.5%. Most patients are asymptomatic and have benign characteristics. Of the nonneoplastic polyps, cholesterol polyps are most common, accounting for 60%-70% of lesions. However, a few polyps have malignant potential. Currently, the guidelines recommend laparoscopic cholecystectomy for polyps larger than 1 cm in diameter due to their malignant potential. The treatment algorithm can be influenced by the size, shape, and numbers of polyps, old age (>50 years), the presence of primary sclerosing cholangitis, and gallstones. This review summarizes the commonly recognized concepts on GB polyps from diagnosis to an algorithm of treatment.

Background: We have previously found that intra-peritoneal lidocaine instillation before pneumoperitoneum attenuates pneumoperitoneum-induced hypertension. Whether this procedure alters patient's hemodynamic status during operation should be determined for clinical application. This study elucidated the possible mechanism of the attenuation of the pneumoperitoneum-induced hypertension by intra-peritoneal lidocaine before pneumoperitoneum. Methods: Thirty-four patients underwent laparoscopic cholecystectomy (LC) were randomly allocated into two groups. After induction of general anesthesia, 200 mL of 0.2% lidocaine (lidocaine group, n=17), or normal saline (control group, n=17) were sub-diaphragmatically instilled 10 minutes before pneumoperitoneum. The changes in systolic blood pressure, heart rate, central venous pressure, stroke volume, cardiac output, and systemic vascular resistance were compared between the groups. The number of analgesics used during post-operative 24 h was compared. Results: Systolic blood pressure was elevated during pneumoperitoneum in both groups (p<0.01), but the degree of elevation was significantly reduced in the lidocaine group than in the control (p<0.01). However, stroke volume and cardiac output were decreased and systemic vascular resistance was increased after induction of pneumoperitoneum (p<0.05) without statistical difference between two groups. The number of analgesics used was significantly reduced in the lidocaine group (p<0.01). Conclusion: These data suggest that intra-peritoneal lidocaine before pneumoperitoneum does not alter patient's hemodynamics, and attenuation of pneumoperitoneum-induced hypertension may be the consequence of reduced intra-abdominal pain rather than the decrease of cardiac output during pneumoperitoneum. Therefore, intra-peritoneal lidocaine instillation before pneumoperitoneum is a useful method to manage an intraoperative pneumoperitoneum-induced hypertension and to control postoperative pain without severe detrimental hemodynamic effects.

복강경담낭절제술은 대부분의 담낭질환 환자의 치료에 널리 쓰이는 수술방법이다. 이 연구의 목적은 복강경담낭절제술의 적용여부를 결정하는 수술전 검사로 행해지고 있는 간담도신티그라피와 경구담낭조영술의 복강경담낭절제술의 난이도 예측에 대한 유용성을 알아보는 것이다. 176명의 환자에서 간담도신티그라피와 경구담낭조영술을 시행하고 한달 이내에 복강경담낭절제술을 시행하였다. 간담도신티그라피와 경구담낭조영술에서 담낭이 관찰되지 않은 소견을 심한 담낭질환을 나타내는 지표를 하여, 환자군을 간담도신티그라피와 경구담낭조영술에서 담낭이 보이는 소견에 따라 나누어서 복강경담낭절제술의 난이도를 나타내는 개복술로의 전환, 수술중 합병증 발생, 수술시간을 비교 분석하였다. 담낭이 보이는 소견에 있어 두 검사의 일치율은 89.2%로 높았다. 두 검사상 담낭이 보이지 않았던 군에서 개복술로의 전환율과 수술중 합병증 발생률이 유의하게 높았으며, 수술시간도 길었다. 결론적으로 간담도신티그라피와 경구담낭조영술 모두 복강경담낭절제술의 난이도를 예측하는데 유용하였으며, 두 검사 사이에 유의한 차이는 관찰되지 않았고 높은 일치율을 보였다. 이러한 결과는 이들 검사를 토대로 복강경담낭절제술의 난이도를 예측가능하게 함으로써 치료방법의 선택과 환자에 대한 상담에 도움을 줄 것으로 생각된다.

Purpose: To report the initial clinical experience with single-incision laparoscopic gastric wedge resection for submucosal tumors. Materials and Methods: The medical records of 10 patients who underwent single-incision laparoscopic gastric wedge resection between July 2009 and March 2011 were reviewed retrospectively. The demographic data, clinicopathologic and surgical outcomes were assessed. Results: The mean tumor size was 2.5 cm (range, 1.2~5.0 cm), and the tumors were mostly located on the anterior wall (4/10) or along the greater curvature (4/10), of the stomach. Nine of ten procedures were performed successfully, without the use of additional trocars, or conversion to laparotomy. One patient underwent conversion to multiport laparoscopic surgery, to get simultaneous cholecystectomy safely. The mean operating time was 66.5 minutes (range, 24~132 minutes), and the mean postoperative hospital stay was 5 days (range, 4~7 days). No serious perioperative complications were observed. Of the 10 submucosal tumors, the final pathologic report revealed 5 gastrointestinal stromal tumors, 4 schwannomas, and 1 heterotopic pancreas. Conclusions: Single-incision laparoscopic gastric wedge resection for gastric submucosal tumors is feasible and safe, when performed by experienced laparoscopic surgeons. This technique provides favorable cosmetic results, and also short hospital stay and low morbidity, in carefully selected candidates.

Background: Preoperative dexamethasone improves the surgical outcome after laparoscopic cholecystectomy(LC). The purpose of this study was to determine the effect of preoperative dexamethasone on the postoperativepain according to age and gender in patients who undergo LC.Methods: In this double blind prospective study, 400 patients, males or females :< 45 yr and males or femaless 65 yr (n = 50 in each of eight groups) who undergoing LC were randomized to receive dexamethasone 8mg (5 ml) or saline 5 ml intravenously 100 minutes before their operation, Postoperative pain was assessedon a visual analog scale (VAS) at 1, 6, 12, and 24 hour, and the time to administering the first postoperativeanalgesics was recorded.Results: Dexamethasone was administered without consideration for age and gender, and it reduced thepostoperative pain VAS score at 1, 6, and 12 hours, and the opioid analgesic requirement, but there was nosignificant difference between administering saline or dexamethasone in the same gender and age groups.Females U 45 yr who were administered saline had the most pain sensitivity and males S 65 yr who wereadministered dexamethasone had the least pain sensitivity.Conclusions: Preoperative dexamethasone reduces the pain intensity and opioid consumption, but does notreduce the pain intensity, according to age and gender in the patients undergoing LC. As a result, Preoperativedexamethasone should be considered for routine use for patients who are undergoing laparoscopic cho-lecystectomy. (Korean J Pain 2008; 21: 51 56)

Backgrounds/Aims: Postoperative delirium (POD) is a common complication that increases mortality and morbidity in older patients. This study aimed to evaluate the clinical significance of post-cholecystectomy delirium in older patients. Methods: This retrospective study included 201 patients aged > 75 years who underwent cholecystectomy for acute or chronic cholecystitis between January 2016 and December 2019. Patients were divided into the POD (n = 21) and non-POD (n = 180) groups, and their demographic features and clinical results were compared. Results: The mean patient age was 78.88 years; the female/male ratio was 44.8%/55.2%. Laparoscopic surgery was performed in 93.5% of patients. The univariate analysis showed that lower body mass index (BMI), immobilized admission status, neuropsychiatric disease history, preoperative intervention (percutaneous drainage), high C-reactive protein, hypoalbuminemia, neutrophilia, hypo-/hyperkalemia, and longer operative time were more frequently observed in the POD group. The multivariate analysis showed that lower BMI (odds ratio [OR], 2.796; p = 0.024), neuropsychiatric disease history (OR, 3.019; p = 0.049), hyperkalemia (OR, 5.972; p = 0.007), and longer operative time (OR, 1.011; p = 0.013) were significant risk factors for POD. Conclusions: POD was associated with inflammation degree, general condition, poor nutritional status, electrolyte imbalance, and stressful conditions. Recognizing risk factors requiring multidisciplinary team approaches is important to prevent and treat POD.
