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.

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.

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.

A barium enema is a diagnostic and therapeutic procedure commonly used for colon and rectum problems. Rectal perforation with extensive intra- and/or extraperitoneal spillage of barium is a devastating complication of a barium enema that leads to a significant increase in patient mortality. Due to the low number of reported cases in recent scientific literature and the lack of experience with the management of these cases, we would like to present our treatment approach to a rare case of retroperitoneal contamination with barium, followed by its intraperitoneal involvement during a diagnostic barium enema. Our experience with long-term management of the patient and the good outcome will be depicted in this paper.

BACKGROUND: Laparoscopic surgery is replacing conventional surgical techniques due to its many advantages. However the possibility of respiratory complications during CO2-induced pneumoperitoneum remain. Tracheal gas insufflation (TGI) has been shown to be a useful adjunct to mechanical ventilation in hypercapneic patients. This study investigated the effectiveness of TGI in reducing the PaCO2 level in hypercapneic patients during laparoscopic surgery without increasing the peak inspiratory pressure (PIP) and usefulness of a Univent tube(R) as a device for TGI. METHODS:Twenty-four patients who were scheduled to undergo gynecological laparoscopic surgery, were enrolled in this study. Anesthesia was induced and maintained with propofol, rocuronium and N2O-O2-sevoflurane. The suction port of the endobronchial blocker of the Univent tube(R) was used for the path of TGI. Data including the ABGA and respiratory parameters were measured three times, the pre-CO2 peritoneum (pre-CO2 pneumoperitoneum point, PCP), 15 min after CO2 peritoneum (after-CO2 pneumoperitoneum point, ACP) and after 15 min TGI (TGI point, TGIP). RESULTS: At ACP, the PaCO2 and PIP had increased more significantly than PCP. After TGI, the PaCO2 was decreased more significantly than ACP, but the PIP did not increased. CONCLUSIONS: TGI is a useful adjunct to mechanical ventilation in hypercapneic patients during laparoscopic surgery, and a univent tube(R) is an economic and convenient device for TGI.

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.
