A case of retroperitoneal teratoma, found in a ten month old female infant was reported. Twenty four hours after the direct retroperitoneal air insufflation, a retrograde pyelography was performed using B.B. 16F. cytoscope. These two studies were essential to make preoperative diagnosis. Review of retroperitoneal tumor was also added.

PURPOSE: This study was conducted to evaluate success and perforation rates of pneumatic reduction and to find the predictors of reduction failure. METHODS AND MATERIALS: We reviewed 224 cases of pediatric intussusception diagnosed by air-enema between July, 1989 and June, 1992. The mean age was 9.8 months(range, 1 month to 3 years). Logistic regression analysis was used to find predictors of reduction failure. RESULTS: Successful reduction was achieved in 197 cases(87.9% of success rate). Bowel perforation occurred in two cases(0.9% of perforation rate). There were two statistically significant predictors of failure;(1) ileoileocolic intussusception(p<.001), (2) long duration of symptom(p<.001). Surgery was performed in 26 cases (11.6%), of which seven required bowel resection. CONCLUSION: Pneumatic reduction is a useful means in the management of pediatric intussusception with a high success rate and no mortality.

Endoscopic thyroidectomy is frequently used for cosmetic reasons, such as reducing cervical scarring. Subcutaneous gas insufflation with CO2 is needed to maintain the surgical space, and optimal surgical techniques and careful attention are required when conducting this procedure due to the limited space available for the endoscopic instruments. We report here a case of a tracheal laceration with a tear in the cuff of a reinforced tube, which was detected by an abrupt increase in end-tidal CO2 to 90 mmHg. Reintubation was achieved using a tube exchanger and the patient was effectively ventilated without complications.

BACKGROUND: Transperitoneal laparoscopy for renal surgery is now a common procedure. Previous studies have suggested that retroperitoneal laparoscopy is associated with greater carbon dioxide absorption. We compared carbon dioxide absorption and hemodynamic variables in patients undergoing transperitoneal laparoscopy for renal or adrenal surgery with that of patients undergoing intraperitoneal laparoscopy for colon surgery. METHODS: Thirty two patients undergoing laparoscopic surgery were divided into laparoscopic renal surgery group (n = 16) and laparoscopic colon surgery group (n = 16). We measured hemodynamic changes and arterial blood gases before CO2 insufflation, 10 minutes, 70 minutes after insufflation and 30 minutes after exsufflation in each groups. RESULTS: There was no significant difference in carbon dioxide absorption in patients who underwent transperitoneal laparoscopy compared to intraperitoneal laparoscopy at any interval. CONCLUSIONS: In contrast to previous reports, our study suggests that transperitoneal laparoscopy is not associated with greater carbon dioxide absorption compared to intraperitoneal laparoscopy.

PURPOSE: Endoscopic thyroidectomy has recently been widely used in clinical practice. The operative method can be classified into CO2gas insufflation and the gasless technique. This study assessed the safety of low pressure CO2gas insufflation (up to 6 mmHg) by performing continuous measurement of the end-tidal CO2 (ETCO2) pressure. METHODS: From March 2003 to October 2006, 95 patients (90 hemithyroidectomies and 5 total thyroidectomies) underwent endoscopic thyroidectomy. The low pressure CO2gas insufflation technique was applied in all cases. The ETCO2 pressure of the patients was measured by capnometry at the time of a pre-gas insufflation status (0 minutes) and at the time of post-CO2gas insufflation (30 minutes) and then it was measured every 30 minutes with also performing capnograms. We analyzed the ETCO2 pressure at the time of the pre-CO2gas insufflation status (0 min) and we compared this with that of each status by using paired T-test. RESULTS: For all 95 cases, the mean patient age was 36.2+/-9.1 (range: 21~57 years), the mean tumor size was 1.7+/-1.1 (range: 0.1~4.5 cm) and the mean operative time was 135.0+/-46.1 (range: 50~340 min). The mean ETCO2 pressure (mmHg) was 33.0+/-3.9 at the time of pre-CO2gas insufflation status (0 min); the mean ETCO2 pressure was 31.1+/-3.7 at 30 min (n=95), 33.5+/-3.7 at 60 min (n=95), 35.2+/-3.6 at 90 min (n=95), 34.9+/-3.7 at 120 min (n=90), 34.6+/-3.8 at 150 min (n=70), 34.1+/-3.4 at 180 min (n=40), 34.3+/-5.2 at 210 min (n=15) and 34.0+/-4.2 at 240 min (n=9). There was a significant difference the early post-CO2gas insufflation status (P<0.05 at 30 min, 90 min, 120 min), but there was no significant difference in the late post-CO2gas insufflation status (P>0.05; at 60 min, 150 min, 180 min, 210 min, 240 min). At each time point, the ETCO2 pressures were all within the normal range. CONCLUSION: We successfully performed endoscopic thyroidectomy with using the low pressure CO2gas insufflation technique and there were no significant complications. We think that performing endoscopic thyroidectomy with using the low pressure CO2gas insufflation technique is a safe procedure.

BACKGROUND: The advantage of a laparoscopic cholecystectomy has led to a trend toward performing it in the elderly. It is well recognised that this can cause changes in respiratory mechanics. However, few studies have measured the effects of abdominal insufflation with CO2 in the elderly. This study was done to evaluate changes in respiratory compliance and peak airway pressure during a laparoscopic cholecystectomy. METHODS: Thirty patients undergoing a laparoscopic cholecystectomy were divided into two groups; aged 65 years or more (elderly group) and under 60 years (control group). A pneumoperitoneum up to an intraabdominal pressure of 12 mmHg was created with CO2 insufflation. Respiratory and peak airway pressure were measured with a continuous spirometry. Measurements were obtained pre-insufflation, just after CO2 insufflation, at 15, 30, 45 and 60 minutes and after abdominal deflation. RESULTS: In both groups, respiratory compliance decreased significantly (P < 0.05) and equally by about 40% after CO2 insufflation. The decrement continued during the pneumoperitoneum, the changes were not significant between the groups. Each group showed an equal improvement immediately after abdominal deflation. No differences between the peak airway pressure during a laparoscopic cholecystectomy was seen in either group. CONCLUSIONS: We have demonstrated that during a laparoscopic cholecystectomy in the elderly the respiratory compliance decreased and peak airway pressure significantly increased as in the control group.
