Laparoscopic Cholecystectomy in High Risk Patients 33<br />

Leone et al [16] presented their cases between January 1994 and December 2000 where there<br />

were 1,100 laparoscopic cholecystectomies for symptomatic gallbladder diseases. They<br />

reported that there were 24 cirrhotic patients who had well-compensated cirrhosis (Child’s<br />

class A or B). The authors reported that there were no operative mortality and the<br />

postoperative complication rates were 20.8%. They estimated that the intraoperative blood<br />

loss was 37.08 ml in average. Their average hospital stay 3.61 days. The authors concluded<br />

that laparoscopic cholecystectomy in patients with compensated cirrhosis is safe and should<br />

be the treatment of choice for these patients. They further stated that laparotomy should be<br />

applied only if the surgeon considers the operation inadequate to be continued<br />

laparoscopically.<br />

7. Patients who are pregnant<br />

Diseases in the abdomen requiring surgical intervention during pregnancy present unique<br />

challenges to their diagnosis and management [17]. These are said to be due to the changes in<br />

physiology and abdominal anatomy characteristic of pregnancy. These changes make<br />

laparoscopic surgery technically more difficult, the obstetrician must determine the status of<br />

pregnancy such as gestational age, viability and inform the patient about the risks related to<br />

pregnancy and surgery itself [18].<br />

There are several mechanisms that have been proposed by specialists for increased fetal<br />

morbidity and mortality associated with laparoscopic surgery during pregnancy including<br />

direct uterine trauma, fetal trauma, intraamniotic CO2 insufflation, trauma to maternal<br />

abdominal organs and vessels, decreased uterine blood flow and oxygen delivery,<br />

teratogenic effects of anesthetic drugs, fetal acidosis due to CO2 pneumoperitoneum,<br />

adverse effects of anesthesia on maternal hemodynamic and acid-base balance, increased<br />

risk of thromboembolic disease, the effect of underlying abdominal pathology, manipulation<br />

during surgery and effects of postoperative medications [18,20] Therefore laparoscopic<br />

cholecystectomy has been used cautiously in pregnant women. This is due to the possible<br />

mechanical problems related to the pregnant uterus and the other is fear of fetal injury<br />

resulting from instrumentation or the pneumoperitoneum.<br />

7.1 Cases<br />

To assess the effects of laparoscopic cholecystectomy on both the mother and the unborn<br />

fetus, Abuabara et al [19] reviewed their surgical experience over a 5-year period where 22<br />

patients ranging from 17 to 31 years underwent laparoscopic cholecystectomy during<br />

pregnancy. They noted that the gestational ages ranged from 5 to 31 weeks where there are<br />

two patients who are in their first trimester, 16 in the second and four in the third. Their<br />

indications for surgery were persistent nausea, vomiting, pain, and inability to eat in 17<br />

patients, acute cholecystitis in three and choledocholithiasis in two. The surgeons<br />

established pneumoperitoneum in all patients and their results were all 22 patients survived<br />

the surgical procedure without complications and there were no fetal deaths or premature<br />

births related to the procedure. The authors concluded that laparoscopic cholecystectomy<br />

during pregnancy is safe for both the mother and the unborn fetus and if at all possible,<br />

when laparoscopic cholecystectomy is indicated, it should be performed either in the second<br />

trimester or early in the third.<br />

Wishner et al [21], members of the Norfolk Surgical Group, gathered their data for the<br />

laparoscopic cholecystectomy cases from May 1991 to June 1994 where they performed the
