Effect of nonbiliary problems on laparoscopic cholecystectomy

Association of severe obesity with risk of conversion to open in laparoscopic cholecystectomy for acute cholecystitis

Background

Obesity is a known risk factor for cholecystitis and is associated with technical complications during laparoscopic procedures. The present study seeks to assess the association between obesity class and conversion to open (CTO) during laparoscopic cholecystectomy (LC).

Methods

Adult acute cholecystitis patients with obesity undergoing non-elective LC were identified in the 2017-2020 Nationwide Readmissions Database. Patients were stratified by obesity class; class 1 (Body Mass Index [BMI] = 30.0-34.9), class 2 (BMI = 35.0-39.9), and class 3 (BMI ≥ 40.0). Multivariable regression models were developed to assess factors associated with CTO and its association with perioperative complications and resource utilization.

Results

Of 89,476 patients undergoing LC, 40.6 % had BMI ≥ 40.0. Before adjustment, class 3 obesity was associated with increased rates of CTO compared to class 1-2 (4.6 vs 3.8 %; p < 0.001). Following adjustment, class 3 remained associated with an increased likelihood of CTO (Adjusted Odds Ratio [AOR] 1.45, 95 % Confidence Interval [CI] 1.31-1.61; ref.: class 1-2). Patients undergoing CTO had increased risk of blood transfusion (AOR 3.27, 95 % CI 2.54-4.22) and respiratory complications (AOR 1.36, 95 % CI 1.01-1.85). Finally, CTO was associated with incremental increases in hospitalization costs (β + $719, 95 % CI 538-899) and length of stay (LOS; β +2.20 days, 95 % CI 2.05-2.34).

Conclusions

Class 3 obesity is a significant risk factor for CTO. Moreover, CTO is associated with increased hospitalization costs and LOS. As the prevalence of obesity grows, improved understanding of operative risk by approach is required to optimize clinical outcomes. Our findings are relevant to shared decision-making and informed consent.

Consecutive laparoscopic gallbladder and spleen resections in cirrhotic patients

AIM: To evaluate the feasibility, safety, and effectiveness of consecutive laparoscopic cholecystectomy (LC) plus splenectomy (LS) in liver cirrhosis patients.

METHODS: From 2003 to 2013, 17 (group 1) patients with liver cirrhosis complicated by hypersplenism and symptomatic gallstones were treated with combined LC and LS, while 58 (group 2) patients with liver cirrhosis and hypersplenism received LS alone. An additional 14 (group 3) patients who received traditional open procedures during the same period were included as controls. Data were retrospectively collected and reviewed in regard to demographic characteristics and preoperative, intraoperative and postoperative features. Differences between the three groups were assessed by statistical analysis.

RESULTS: The three groups showed no significant differences in the demographic characteristics or preoperative status. However, the patients treated with LC and LS required significantly longer operative time, shorter postoperative stay as well as shorter time of return to the first oral intake, and suffered less intraoperative blood loss as well as fewer postoperative surgical infections than the patients treated with traditional open procedures (group 1 vs group 3, P < 0.05 for all). The patients treated with LC and LS showed no significant differences in the intraoperative and postoperative variables from those treated with LS alone (group 1 vs group 2). All patients showed significant improvements in the haematological responses (preoperative period vs postoperative period, P < 0.05 for all). None of the patients treated with LC and LS presented with any gallstone-associated symptoms following discharge, while the patients treated with the traditional open procedures expressed complaints of discomfort related to their surgical incisions.

CONCLUSION: Consecutive LC and LS is an appropriate treatment option for liver cirrhosis patients with gallstones and hypersplenism, especially for those with Child-Pugh A and B.

A recommended laparoscopic procedure for implantation of microcapsules in the peritoneal cavity of non-human primates

BACKGROUND

The anatomical spatial distribution of microencapsulated islets transplanted into the peritoneal cavity of large animals remains a relatively unexplored area of study. In this study, we developed a new implantation approach using laparoscopy in order to avoid microcapsule amalgamation. This approach constitutes a clinically relevant method, which can be used to evaluate the distribution and in vivo biocompatibility of various types of transplanted microcapsules in the future.

MATERIALS AND METHODS

Two healthy baboons were implanted intraperitoneally with microencapsulated islets through mini-laparotomy and observed at 76 d after implantation. Nine baboons underwent laparoscopic implantation of approximately 80,000 empty microcapsules. Microcapsule distribution was observed by laparoscopic camera during and after implantation at 1, 2, and 4 wk. At each time point, microcapsules were retrieved and evaluated with brightfield microscopy and histologic analysis.

RESULTS

Mini-laparotomic implantation resulted in microcapusle aggregation in both baboons. In contrast, laparoscopic implantation resulted in even distribution of microcapsules throughout the peritoneum without sedimentation to the Douglas space in all animals. In eight out of nine animals, retrieved microcapsules were evenly distributed in the peritoneal cavity and presented with no pericapsular overgrowth and easily washed out during laparoscopic procedure. The one exception was attributed to microcapsule contamination with blood from the abdominal wall following trocar insertion.

CONCLUSIONS

Laparoscopic implantation of microcapsules in non-human primates can be successfully performed and prevents microcapsule aggregation. Given the current widespread clinical application of laparoscopy, we propose that this presented laparoscopy technique could be applied in future clinical trials of microencapsulated islet transplantation.

Laparoscopic cholecystectomy in cirrhotic patients

BACKGROUND AND OBJECTIVES

Gallstones are twice as common in cirrhotic patients as in the general population. Although laparoscopic cholecystectomy (LC) has become the gold standard for symptomatic gallstones, cirrhosis has been considered an absolute or relative contraindication. Many authors have reported on the safety of LC in cirrhotic patients. We reviewed our patients retrospectively and assessed the safety of LC in cirrhotic patients at a tertiary care hospital in Pakistan.

METHODS

From January 2003 to December 2005, a retrospective study was conducted at SU IV, Liaquat University of Medical & Health Sciences Jamshoro. All the cirrhotic patients with Child-Pugh class A and B cirrhosis undergoing LC were included in the study. Cirrhosis was diagnosed based on clinical, biochemical, ultrasonography, and intraoperative findings of the nodular liver and histopathological study.

RESULTS

Of 250 patients undergoing laparoscopic cholecystectomy, 20 (12.5%) were cirrhotic. Of these 20, 12 (60%) were Childs group A and 8 (40%) were group B. Thirty percent were hepatitis B positive, and 70% were hepatitis C positive. Preoperative diagnosis of cirrhosis was possible in 80% of cases, and 20% were diagnosed during surgery. Morbidity rate was 15% and mortality rate was 0%. Two patients developed postoperative ascites, and mean hospital stay was 2.8+/-0.1 days. Of the 20 cases, 2 (10%) were converted to open cholecystectomy. The mean operation time was 70.2+/-32.54 minutes.

CONCLUSION

Laparoscopic cholecystectomy is an effective and safe treatment for symptomatic gallstone disease in select patients with Child-Pugh A and B cirrhosis. The advantages over open cholecystectomy are the lower morbidity rate and reduced hospital stay.

Laparoscopic cholecystectomy in cirrhotic patients with symptomatic cholelithiasis: a case-control study

BACKGROUND

In this study we retrospectively evaluated a group of symptomatic cirrhotic (n=30) and non-cirrhotic (n=60) patients submitted to laparoscopic cholecystectomy (LC) in a public hospital in Brazil.

METHODS

The groups were compared for surgical time, duration of hospitalization after surgery, period of permanence in the intensive care unit (ICU), use of blood derivatives, mortality rates, and transoperative and post-surgery complications. Other parameters, such as hepatic reserve capacity and presence of ascites, were also analyzed.

RESULTS

Twenty-three (76.7%) of the patients of the cirrhosis group (CG) were classified as Child-Pugh A, and seven (23.3%) were Child-Pugh B. Six of them (20%) had ascites. Differences between the two groups included surgery time (p=0.008), duration of hospitalization (p=0.014), and post-surgery (p=0.000) or ambulatory (p=0.008) complications. The worst results were observed among Child B patients and in those with ascites. Blood derivatives were used in only 3.3% of the CG patients. No cases of conversion to laparotomy were observed among the two groups of patients included in this study, nor were there any deaths.

CONCLUSIONS

These results indicate that videolaparoscopic cholecystectomy may be safely performed in public hospitals in Brazil, with low levels of complications, no associated mortality, and no need for blood derivatives.

[Laparoscopic cholecystectomy in patients with liver cirrhosis]

BACKGROUND

Initially considered a contraindication to the surgical laparoscopy, cirrhosis have been an occasional discovery during this procedure. Until now many series reported in the literature suggest that the majority of the surgeons still consider cirrhosis as contraindication to the laparoscopic cholecystectomy.

AIM

To evaluate our experience in laparoscopic treatment of the cholelithiasis in cirrhotic patient.

PATIENTS AND METHODS

Six hundred and four patients with symptomatic cholelithiasis were operated on Clinical and Surgical Gastroenterology Unit, "Santa Casa de Misericórdia de Porto Alegre", Porto Alegre, RS, Brazil, during the period from May 1993 to May 2000. Of these, 10 (1,6%) presented hepatic cirrhosis. The patients' age was between 22 and 69 years (average of 50,4 +/- 18,1). Eight patients (80%) were female. The alcohol was the etiological factor in four, chronic hepatitis B and C, primary biliary cirrhosis and of alfa-1 antitripsin deficiency in one patient each. In two patient the causal agent was not identified.

RESULTS

Cholecystectomy was accomplished in all patients and in seven also diagnostic hepatic biopsy. In two (20%) the surgery was converted. The result of the intraoperative cholangiography was normal in all cases. In seven patients the postoperative was uneventfull. Clinically controlled ascite was observed in two (20%). Both were Child A at the moment of the surgery. The last patient, Child C, died. He presented irreversible hepatic failure.

CONCLUSIONS

Despite larger experience still should be acquired, it seems that laparoscopic is a safe approach in well compensated cirrhotic patients with symptomatic cholelithiasis. In Child C patients we believed that all of the efforts should be driven to the improvement of the hepatic function or a less invasive method such as cholecystostomy.

Retroperitoneal access for transperitoneal laparoscopy in patients at high risk for intra-abdominal scarring

BACKGROUND AND PURPOSE

Adhesions from prior extensive open abdominal surgery can make initial transperitoneal access for laparoscopy hazardous. An alternative to open port placement is a retroperitoneal approach to the peritoneal cavity. We describe our retroperitoneal access for transperitoneal laparoscopy and evaluate the success of the subsequent laparoscopic procedure.

PATIENTS AND METHODS

Eight patients with a history of abdominal surgery have undergone retroperitoneal access to the peritoneum prior to a laparoscopic urologic procedure. With the patient in a lateral decubitus position, the retroperitoneum is entered with a 10-mm Visiport device (US Surgical Corp., Norwalk, CT) along the posterior axillary line. A working space is bluntly created, the peritoneum identified anterior to the colon, and the endoscope passed through a peritoneotomy. The abdomen is then inspected, transperitoneal ports are strategically placed under direct vision, and the intended procedure is commenced.

RESULTS

In all cases, retroperitoneal access to the peritoneum and subsequent trocar placement was successful. In five cases, the intended procedure was completed laparoscopically. In a case of bilateral ureterolysis, one side was completed laparoscopically; however, the other required open conversion. In two nephrectomies for xanthogranulomatous pyelonephritis (XGP), open conversion was necessary because of fibrosis.

CONCLUSION

Retroperitoneal access to the peritoneal cavity permits safe and effective port placement when previous abdominal surgery makes initial transabdominal access difficult. However, despite successful access, in patients at risk for extensive perinephric fibrosis (e.g., XGP), a high incidence of open conversion may be expected.

Laparoscopic Procedures in Pregnancy

As the applications of laparoscopy for general surgical procedures expanded in the 1990s, pregnancy was initially considered a contraindication. Several case reports have suggested the safety of laparoscopy in pregnancy. Previous clinical studies indicate a higher fetal mortality may exist and advised caution. To evaluate the fetal outcome of laparoscopic procedures in pregnant patients at our institution, we retrospectively reviewed the medical records between 1991 and 1997 and identified 21 pregnant patients who underwent either a laparoscopic (n = 12) or open (n = 9) procedure. Appendectomies, cholecystectomies, and diagnostic laparoscopics were performed. Specific variables including age, length of procedure, hospital stay, duration of parenteral analgesic use, gestational age at the time of surgery and delivery, O2 saturation and EtCO2 during surgery, APGAR scores, and birth weights were compared between the two groups. Laparoscopic procedures during pregnancy resulted in shorter hospital stays (34 hours versus 91 hours; P = 0.01), less use of parenteral narcotic analgesics (5 hours versus 29 hours; P = 0.05), and no prolongation of operative times (51 minutes versus 63 minutes; P = 0.20). In addition, laparoscopy was performed at earlier gestational ages (12 weeks versus 29 weeks; P = 0.001). There was one miscarriage 7 days after a laparoscopic cholecystectomy early in the 1st trimester that was not statistically significant. Our experience did not show a higher incidence of fetal loss when comparing laparoscopic to open procedures in pregnant patients.

Laparoscopic cholecystectomy during pregnancy: a case series and review of the literature

This study was conducted to evaluate the role of antepartum laparoscopic cholecystectomy (LC). Patients who underwent LC were identified from a hospital database with the use of CPT/ICD codes. Of 2093 cases performed at a major center (October 1991 to November 1997), only six were performed during pregnancy. On reviewing the English literature, gestational age at surgery and delivery and outcome of delivery were provided in only 69 of 105 patients (33 papers with 1-10 cases) and we tabulated different variables from the cases in this review. In this series, two patients who had LC in the first trimester underwent elective termination of pregnancy. Of the seven published cases of first trimester LC followed to delivery, one had preterm delivery. First trimester open cholecystectomy (OC) has a 12 percent spontaneous abortion rate. The four patients who had second trimester LC had normal deliveries at term. Of the 43 published cases of second trimester LC followed to delivery, 39 ended in uncomplicated, full-term deliveries. Three of four second trimester cases at one institution had spontaneous abortions. None of our patients underwent LC in the third trimester. Of the 12 published cases of third trimester LC followed to delivery, one had preterm delivery. Third trimester OC is reported to have a 40 percent rate of preterm delivery. There were no intraoperative cholangiograms (IOC), prophylactic or postoperative use of tocolytics, or intraoperative fetal monitoring in our series. We added six cases of LC during pregnancy to the previously reported 105 cases. The successful outcome in all trimesters suggests that LC is a safe procedure throughout pregnancy; however, surgery in the second trimester is preferable. Compared with OC, there is a decreased risk of spontaneous abortion in the first trimester and preterm labor in the third trimester.

Colelitíase e cirrose hepática

Considerando que são duas doenças freqüentes na população, a associação entre cirrose hepática e colelitíase também é um achado comum. É importante o conhecimento desta situação porque a evolução clínica da cirrose pode ser complicada pela presença de colelitíase e, ao contrário, uma colelitíase sintomática pode ser de difícil tratamento nos pacientes cirróticos. Os autores fazem uma revisão da literatura enfocando os aspectos clínicos e terapêuticos desta associação.

Laparoscopic renal surgery in patients at high risk for intra-abdominal or retroperitoneal scarring

Prior open abdominal or renal surgery has been considered a relative contraindication to laparoscopic surgery because of the likelihood of adhesion formation and perinephric scarring, which results in difficulty obtaining access to the peritoneal cavity and during surgical dissection. The purpose of this study was to examine the feasibility and morbidity of laparoscopic renal surgery in patients at high risk for intra-abdominal or retroperitoneal scarring. Twenty-four patients who underwent laparoscopic renal surgery at our institution gave a history of significant open abdominal or renal surgery. Seven patients had undergone prior open extraperitoneal (N = 6) or percutaneous (N = 1) renal procedures, 10 patients had undergone prior open laparotomy for various reasons, and 7 patients had undergone open pelvic surgery. The mean interval from the prior operation to laparoscopic renal surgery was 16.5 years (range 0.3-44 years). Operative time, estimated blood loss, incidence of complications, perioperative parenteral narcotic use, length of hospitalization convalescence, and degree of intra-abdominal and retroperitoneal scarring were assessed. Patients who developed complications were compared with patients who did not. No difficulty was encountered while obtaining initial access to the peritoneal cavity or retroperitoneal space. No bowel or visceral injuries occurred during Veress needle or trocar placement. The laparoscopic procedure was completed successfully in all cases. The mean operative time was 4.3 (range 2.0-10.9) hours. The mean estimated blood loss was 266 mL (range 50-1200 mL). There were eight complications (overall complication 33%) including three major and five minor complications. Patients who developed complications had a higher total scarring score that those who did not (p = 0.01). For experienced laparoscopic surgeons, laparoscopic renal surgery in patients who have a history of open abdominal or renal surgery can be successful. Access via the transperitoneal or retroperitoneal route can be obtained safely, and the procedure usually can be performed in a timely fashion. However, a relatively high perioperative complication rate can be expected, particularly for those patients with significant intraperitoneal and retroperitoneal scarring.

Gastrointestinal surgery during pregnancy

Gastrointestinal surgical problems often mimic symptoms and signs of nonsurgical conditions that occur during pregnancy. This mimicry presents a particular challenge to diagnosis because avoiding a delay in treatment is critical to successful management. Some of these conditions, such as acute appendicitis and biliary colic, are common in younger women; however, the anatomic and physiologic changes of pregnancy can alter their usual manner of presentation. Many elective and urgent operations can be performed during pregnancy with minimal risk to the mother and fetus. The mother's condition should always take priority because her proper treatment usually benefits the fetus as well.

Postoperative complications of cholecystectomy in Victorian public hospitals

Cholecystectomies in Victorian public hospitals were evaluated by analysis of hospital morbidity data. The Victorian Inpatient Minimum Dataset (VIMD) contains data on postoperative complications from all cholecystectomies in Victorian public hospitals. Hospital separations associated with cholecystectomy were identified according to Australian national diagnosis-related groups and the procedures were grouped as open, laparoscopic or conversion from laparoscopic to open cholecystectomy (conversion). Postoperative complications were identified by ICD9-CM external-cause codes (E-codes) in the VIMD. The 35593 cholecystectomies performed between 1987-88 and 1993-94 were analysed. A further detailed analysis of all cholecystectomies performed in 1993 was based on logistic regression. This identified the adjusted odds (AOR) of occurrence of complications and included covariates of age, sex, admission type, diagnosis-related group and hospital identification code. The annual frequency of cholecystectomy increased after introduction of laparoscopic cholecystectomy in 1990, and was associated with an increase in rates of separations having adverse events, but laparoscopic cholecystectomy had the lowest rate (66.7 per 1000 separations). Adverse-event rates for open procedures increased to 157.5 per 1000 in 1993-94, and for conversions to 290.0 per 1000. Of 5627 cholecystectomies in 1993, 74.4 per cent were laparoscopic, 21.5 per cent open and 4.1 per cent conversions. Postoperative complications were more likely in males (AOR 1.67, 95 per cent confidence interval (CI) 1.38 to 2.04), in patients admitted as an emergency (1.27, CI 1.01 to 1.60), and in those having open cholecystectomies (2.25, 1.78 to 2.85) or conversions (4.29, 3.05 to 6.03). Analysis of the VIMD has provided information for the evaluation of cholecystectomy. The VIMD is a useful tool for monitoring postoperative complications and the quality of care in Victorian hospitals.

Laparoscopic surgery during pregnancy

BACKGROUND

Animal studies have demonstrated fetal acidosis during carbon dioxide pneumoperitoneum. This finding suggests a potential adverse effect of CO2 pneumoperitoneum on fetal outcome in humans.

PATIENTS AND METHODS

We reviewed our recent experience with laparoscopic surgery performed under general anesthesia and with the use of CO2 pneumoperitoneum, in pregnant women with appendicitis or cholecystitis. We compared these women's charts and pregnancy outcomes with those of pregnant women who underwent formal laparotomy during the same period of time.

RESULTS

Seven pregnant patients underwent laparoscopic surgery, and there were 4 fetal deaths among them (3 during the first postoperative week, and another 4 weeks postoperatively). Five pregnant patients underwent formal laparotomy, of whom 4 subsequently progressed to term and 1 was lost to follow-up.

CONCLUSIONS

Our recent experiences together with the available animal data suggest that caution should be used when considering nonobstetrical laparoscopic surgery in pregnant women. This experience suggests that additional clinical and laboratory investigations may be indicated to evaluate fetal risk associated with such surgery.

Complications of laparoscopic cholecystectomy

Video technology allows surgeons to offer patients operations through small incisions. While these minimally invasive techniques have been employed for a wide range of operations for many years, only recently has a laparoscopic cholecystectomy been possible. Compared to the same operation performed via laparotomy, it is deemed the "gold standard." Overall mortality after laparoscopic cholecystectomy ranges from 0-1%, and the rate of major complications is less than 5%. As a group, general surgeons are beyond their initial learning curve for laparoscopic cholecystectomy, but the majority of iatrogenic injuries can be successfully avoided by appreciating the limitations and pitfalls of laparoscopic surgery, and by carefully dissecting the hepatocystic triangle before dividing any structure. Early identification and management of complications will minimize potentially devastating complications of small, unrecognized injuries. Physicians need to accurately advise patients of the proposed advantages and potential problems of laparoscopic cholecystectomy before referring them to a surgeon.

Laparoscopic cholecystectomy during pregnancy

BACKGROUND

Cholecystectomy represents the second most common nonobstetric operation during pregnancy. Published guidelines for laparoscopic cholecystectomy (LC) have considered it to be contraindicated in the gravid patient. Several cases of successful LCs in the gravid patient have been reported recently. This study reviews LC during pregnancy in my series and compares this experience with the published literature.

METHODS

Five LCs were performed during pregnancy out of 380 cases between May 1990 and November 1994. Forty-one cases were retrieved via MEDLINE search.

RESULTS

Three patients were in their second trimester (14, 17, and 22 weeks), and two patients were in the third trimester (27.5 and 28 weeks) in my series. The open technique was used in one patient. Intraoperative cholangiography was not performed. No maternal or fetal morbidity occurred. Forty-one cases have been reported in the literature. Four patients were operated on during the first trimester, 35 during the second trimester, and two during the third trimester (range, 3 to 31 weeks) without fetal loss or maternal morbidity. Cholangiography was performed in 15 cases. Tocolytic agents were used in five of 46 patients.

CONCLUSIONS

Although additional clinical data are required, laparoscopic cholecystectomy is safe during pregnancy when undertaken by the skilled laparoscopic surgeon.

Acute cholecystitis with calculous biliary duct obstruction in the gravid patient. Management by ERCP, papillotomy, stone extraction, and laparoscopic cholecystectomy

The pregnant patient with cholelithiasis is subject to the manifold complications associated with this disease. The management of a gravid patient with acute cholecystitis complicated by biliary duct obstruction utilizing combined endoscopic therapy and laparoscopic cholecystectomy is reported. The benefits to the patient and fetus when successful are apparent, but it is important to anticipate potential problems associated with laparoscopy in pregnancy and to avoid them. Various safeguards such as fetal monitoring, careful trocar placement, and intra-abdominal pressure monitoring have been suggested and should be appropriately utilized to enable a satisfactory outcome. Case reports such as this may further clarify the interdependent role of laparoscopic cholecystectomy and ERCP and their application to the pregnant patient.

Laparoscopic surgery in pregnancy: report on two cases

Laparoscopic cholecystectomy (LC) and laparoscopic appendectomy (LA) are well-established surgical procedures. Although pregnancy initially was considered a contraindication to laparoscopic surgical procedures, successful reports of LC and LA during pregnancy have appeared in the surgical literature. Two cases are presented in this report, one LC and one LA, both in second-trimester pregnancies. Both pregnancies contained undisturbed and ended with spontaneous vaginal delivery of healthy infants. Laparoscopic surgery in pregnant patients is feasible and provides a reasonable alternative to the standard surgical approach.

The surgical management of intra-abdominal inflammatory conditions during pregnancy

The timely diagnosis and treatment of intra-abdominal conditions during pregnancy can challenge the surgical consultant. Familiarity with the anatomic and physiologic changes present in normal pregnancy is essential, as is the knowledge of relative risk by trimester. The general surgeon will be called upon to diagnose and treat appendicitis, biliary tract disease (including pancreatitis), and liver disease. Knowledge of how these conditions become manifest is essential. The surgical consultant should be aware that virtually all complications that occur in the management of these conditions are caused by delay in the detection of the disease process.

Laparoscopic cholecystectomy in pregnancy: two case reports

Laparoscopic cholecystectomy (LC) was previously avoided in pregnancy. Two cases of LC performed in gravid women with recurrent symptoms of biliary disease are reported.

Role of laparoscopic cholecystectomy in the management of acute gallstone pancreatitis

Laparoscopic cholecystectomy has rapidly become the prime modality for removal of the gallbladder. However, as laparoscopic techniques for treating choledocholithiasis are evolving, we reviewed our experience with acute gallstone pancreatitis since the inception of laparoscopic cholecystectomy. Between November 1989 and March 1993, we treated 57 patients with acute gallstone pancreatitis. Cholecystectomy was performed during the initial admission in 46 patients (81%, group I), while 11 (19%) underwent delayed cholecystectomy at a second admission 2 to 9 weeks later (group II). Within group I, eight patients (17%) were thought to have contraindications to laparoscopic cholecystectomy and underwent open cholecystectomy. In the remaining 38 patients of group I, laparoscopic cholecystectomy was completed successfully. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 23 of these patients (61%) and endoscopic sphincterotomy was performed in 6 patients (26%). In four other patients, the intraoperative cholangiogram revealed common bile duct stones that were removed using laparoscopic techniques. The 11 patients in group II were all treated by laparoscopic cholecystectomy; of these patients, 3 underwent preoperative endoscopic stone removal and 1 had choledocholithiasis managed laparoscopically. Postoperative hospitalization averaged 4 +/- 1 days (mean +/- SEM), and there was no major morbidity or 30-day mortality. This is the first large series of acute gallstone pancreatitis in the era of laparoscopic cholecystectomy. Our experience suggests that laparoscopic cholecystectomy with or without ERCP should be the primary approach for treating acute gallstone pancreatitis in the 1990s.
