Extensive subcutaneous emphysema and hypercapnia during laparoscopic cholecystectomy: two case reports.

We report two cases of marked hypercapnia of more than 60 mm Hg (PaCO2) and extensive subcutaneous emphysema noted during laparoscopic cholecystectomy. The first case, a 55-year-old man was diagnosed as having cholecystolithiasis and had hypercapnia up to 83.5 mm Hg (PaCO2) during laparoscopic cholecystectomy. The patient resumed spontaneous respiration under controlled ventilation accompanied by persistent bigeminal pulse. Soon after deflation, CO2 returned to normal range, and extensive subcutaneous emphysema was detected in the recovery room. The second patient, a 53-year-old woman, had cholecystolithiasis and also underwent laparoscopic cholecystectomy. Both hypercapnia rising to 61.1 mm Hg (PaCO2) and extensive subcutaneous emphysema appeared just before completion of resection of the gallbladder. Mild hypercapnia during pneumoperitoneum of about 50 mm Hg (PaCO2) has been reported previously. As compared with cases in the literature, the present cases suggest that hypercapnia is due to extensive subcutaneous emphysema. The large absorption surface area in the subcutaneous tissue and the large difference in the partial pressure cause the extensive gaseous interchange of CO2 between subcutaneous tissue and blood perfusing into it at the moment between peritoneal cavity and blood perfused the peritoneum.

Abdominal wall lifting with subcutaneous wiring: an experience of 50 cases of laparoscopic cholecystectomy without pneumoperitoneum.

Abdominal wall lifting is a method to produce operative space between the anterior abdominal wall and the intra-abdominal organs during laparoscopic surgery. We devised a hanger lifting procedure for the anterior abdominal wall to avoid complications as well as reduce the costs related to the pneumoperitoneum. In our series, we performed 50 cases of laparoscopic cholecystectomy with this abdominal wall-lifting procedure. Though at the beginning we performed laparoscopic cholecystectomy by the pneumoperitoneum, we discarded the insufflator for this operation since starting the new procedure. There was no incidence of conversion to pneumoperitoneum and a fairly good operative view was achieved enabling a smooth laparoscopic cholecystectomy.

Ojigi tying spatula: a newly developed movable spatula for laparoscopic ligation.

We developed a new type of movable tying spatula for ligation of the cystic duct and artery in laparoscopic cholecystectomy. This spatula can be used to ligate any vascular or ductal structure before laparoscopic resection. This instrument should give strong support to surgeons performing laparoscopic procedures and eventually will replace the expensive clips and Endoloops.

Stones in a long pancreaticobiliary common channel: a rare cause of obstructive jaundice and pancreatitis.

A case of obstructive jaundice associated with acute pancreatitis is reported. The underlying cause was a dilated long pancreaticobiliary common channel impacted with stones and bile debris. There was no stone in the rest of the biliary system except for one in the lowest part of the common bile duct and the overall appearance of the stones suggested that they originated within the common channel itself. A long common channel may be an underlying cause of various pathological conditions in the pancreaticobiliary system. Early operative intervention is recommended when such a diagnosis is made.

Laparoscopic cholecystectomy: an approach without pneumoperitoneum.

Diagnostic pneumoperitoneum, which has been considered the first step of any laparoscopic procedure, is no longer an absolute necessity. We devised an alternative to pneumoperitoneum or abdominal insufflation by upward and outward traction on the anterior abdominal wall with a "hanger lifting method" using subcutaneous wiring. Fairly good room was produced intraabdominally, which was enough in which to perform the cholecystectomy procedure. We have successfully performed 40 cases of laparoscopic cholecystectomy with this procedure. No complication was experienced with this method and, moreover, excess instrumentation and complications related to pneumoperitoneum were avoided.

Carotid artery pseudoaneurysm following internal jugular vein cannulation.

A case of right common carotid artery pseudoaneurysm following internal jugular vein cannulation is reported. The aneurysm appeared three days after removal of the catheter, which had been in the right internal jugular vein for three weeks. There was a pin-hole communication between the common carotid artery and the pseudoaneurysm, which was successfully obliterated by surgery. Carotid pseudoaneurysm formation is a rare complication of internal jugular vein cannulation, and there has been no report of its formation after apparently successful jugular vein cannulation. This complication is difficult to predict, and careful observation after removal of the catheter is mandatory.
