Is cell-mediated immunity affected by laparoscopic cholecystectomy?

It is well known that surgery significantly decreases cell-mediated immunity. Laparoscopic cholecystectomy is a so-called minimally invasive surgical procedure, and on the basis of this consideration we investigated whether and how the immune system is modified in patients after laparoscopic cholecystectomy compared to those undergoing open cholecystectomy. Immune activity (neutrophils, total lymphocyte count, lymphocyte subpopulations, multiple skin tests) was evaluated in 82 patients on postoperative day 1 and on postoperative days 1, 3 and 6. Forty-two patients underwent open cholecystectomy and 40 laparoscopic cholecystectomy. On postoperative day 1 patients treated by open cholecystectomy showed a significant increase (P < 0.05) in plasma neutrophils, whereas this parameter was unchanged in patients undergoing laparoscopic cholecystectomy. Skin tests revealed a hypo- or anergic response in the majority of patients (81.8%) undergoing open surgery compared to those treated laparoscopically (10.5%). Total lymphocyte count and lymphocyte subpopulations were normal in the two groups. Four cases of respiratory tract infection (4.8%) were detected after open cholecystectomy. Laparoscopic cholecystectomy substantially reduces postoperative pain and hospitalisation, promotes an earlier recovery and return to normal activity and is not associated with postoperative immunosuppression, with a more positive postoperative morbidity profile compared to open surgery.     

Gallbladder carcinoma during laparoscopic cholecystectomy: is it associated with bad prognosis?

Laparoscopic cholecystectomy is the treatment of choice for gallstone disease. The ultrasonogram has failed for the early detection of gallbladder cancer, especially if inflammation (chronic or acute) is present. Incidental gallbladder could be an important cancer finding during laparoscopic cholecystectomy, due to the potential cancer cell dissemination during the procedure. In our Department, 6500 laparoscopic cholecystectomies have been performed in the last 5 years and in 15 cases (0.23%) gallbladder cancer was found during surgery or after histological examination of the resected gallbladder. In none of these 15 patients was pre-operative diagnosis of gallbladder carcinoma postulated. When re-evaluation of the pre-operative ultrasonograms was done, it was possible to observe signs suggesting the presence of neoplastic infiltration in 4 of them (28.6%). During videoscopic exploration, also in 4 patients, the suspicion of gallbladder cancer was noted. Laparoscopic cholecystectomy was completed in 9 patients. In 2 of them, in situ or mucosal invasion was demonstrated with a long survival. One patient presented recurrence at the biliary hilum 2,5 years after surgery. Six patients were re-operated and in 4 of them peritoneal or port site metastasis was found; all died early (4.5 month median survival). The other 2 patients were submitted to liver bed resection and lymph node dissection. These patients are free of cancer recurrence after 15 months of follow-up. Six patients were converted to open surgery, performing palliative procedures and died before the 12 month follow-up. The suspicion of pre-operative gallbladder cancer is generally unlikely to be confirmed based on ultrasonographic signs; but, in some cases with high suspicion, further investigation (TAC, tumor markers, etc.) must be indicated in order to avoid poor results. Laparoscopic cholecystectomy could be associated with bad prognosis, and then, when gallbladder cancer is suspected during the laparoscopic procedure, conversion to open surgery could be the best choice.     

Early laparoscopic cholecystectomy for acute cholecystitis: A safe procedure

Acute cholecystitis is increasingly managed by laparoscopic cholecystectomy. Some reports have shown conversion and complication rates that are increased in comparison to elective laparoscopic cholecystectomy. This study reviews the combined experience of two hospitals where the intention was to perform early laparoscopic cholecystectomy for acute cholecystitis. A total of 152 cases of laparoscopic cholecystectomy for acute cholecystitis (evidence of acute inflammation clinically and pathologically) were identified. Conversion to open cholecystectomy was required in 14 cases (9%) in the total series. Laparoscopic cholecystectomy was performed within 2 days of admission in 76% (115 of 152) of patients. Conversion was significantly less likely in patients undergoing laparoscopic cholecystectomy within 2 days of admission (4 of 115) compared to those undergoing surgery beyond 2 days (10 of 37; P <0.0001). Eleven patients (7%) had postoperative complications; however, there were no cases of injury to the biliary system and no perioperative deaths. This series shows that laparoscopic cholecystectomy can be performed safely in patients with acute cholecystitis and suggests that early laparoscopic cholecystectomy is preferable to delaying surgery. Although the conversion rate to open surgery is higher than for elective cholecystectomy, the majority of patients (91 %) still derive the well-recognized benefits of laparoscopic cholecystectomy. Early laparoscopic cholecystectomy is an acceptable approach to acute cholecystitis for the experienced laparoscopic surgeon.     

Open versus laparoscopic cholecystectomy for gallbladder carcinoma

Laparoscopic surgery has replaced conventional open cholecystectomy for benign gallbladder disease. A major concern is how to handle gallbladder cancer in the laparoscopic era, since there are numerous case reports of port site metastases from gallbladder cancer after laparoscopic cholecystectomy. There are also many experimental studies favoring the opinion that the laparoscopic technique implies a higher risk of spreading malignant disease. This opinion has gained wide acceptance despite little previous clinical effort to determine the risk of tumor dissemination and the lack of comparisons between open and laparoscopic surgery. This report is a short summary of our own studies and present knowledge with special respect to the clinical aspects of the development and incidence of abdominal wall metastases. Among 270 patients with verified gallbladder carcinoma in whom 210 had open surgery and 60 a laparoscopic cholecystectomy, 12 patients (6.5%) in the open cholecystectomy group and 9 (15%) in the laparoscopic group developed incisional metastases. Although the sparse clinical documentation does not unavoidably mean that laparoscopic cholecystectomy has an increased risk of disseminating tumor cells, we recommend open surgery in cases of known or suspected gallbladder carcinoma.

Reasons and risk factors for intraoperative conversion from laparoscopic to open cholecystectomy

Purpose

The aim of this study was to analyze the reasons and risk factors for intraoperative conversion from laparoscopic cholecystectomy to open cholecystectomy.

Methods

The study involved 407 patients in whom laparoscopic cholecystectomy was planned between January 1998 and July 2006. The patients were divided into two groups (the LC completed group and the conversion group), and the two groups were compared.

Results

Laparoscopic surgery was intraoperatively converted to open surgery in 47 cases (11.6 %). The reasons for the conversion consisted of adhesions (15 cases), inflammation (8 cases), adhesion plus inflammation (9 cases), bleeding (8 cases), common bile duct injury (4 cases), suspected common bile duct injury (1 case), injury of the duodenal bulb (1 case) and respiratory disorder (1 case). The group of patients who required conversion to open surgery had a significantly higher percentage of males (P = 0.042) and prevalence of acute cholecystitis (P < 0.001) than the group of patients for whom laparoscopic surgery could be completed. A multivariate logistic regression analysis of these significant predictors showed that male sex [odds ratio (OR) 1.95] and acute cholecystitis (OR 8.45) were significant.

Conclusion

Particular attention is needed when laparoscopic surgery is considered for male patients with acute cholecystitis.

Laparoscopic vs open surgery

BACKGROUND: The purported advantages of laparoscopic surgery over conventional open techniques are less pain and faster return to normal functional status. Very few studies have included validated measures of quality of life as end points. This study prospectively assessed the health status outcomes of patients undergoing four types of laparoscopic and open operations. METHODS: Preoperatively, patients undergoing elective inguinal hernioplasty, esophageal surgery, cholecystectomy, and splenectomy completed the SF-36, a well-tested, validated health-status instrument. This instrument measures physical functioning (PF), role-physical (RP), role-emotional (RE), bodily pain (BP), vitality (VT), mental health (MH), social functioning (SF), and general health (GH) health status domains. Patients then underwent either laparoscopic or open surgery. Patients were reassessed with the instrument > or =6 weeks after surgery. A total of 100 patients underwent these procedures. RESULTS: Compared to preoperative values, median SF-36 scores for laparoscopic cholecystectomy patients were improved in the domains of PF (85 vs 95, p = 0.01), BP (42 vs 75, p = 0.002), and VT (47.5 vs 70, p = 0.04); open cholecystectomy patients did not show statistically significant improvements over preoperative values. In addition, laparoscopic cholecystectomy patients had a better score than open cholecystectomy patients in the BP domain (75 vs 41, p = 0.05). Laparoscopic esophageal surgery patients had better scores than open surgery patients in the domains of RP (100 vs 0, p = 0.02) and VT (65 vs 52.5, p = 0.05). Compared to preoperative values, laparoscopic splenectomy patients had an improved score in GH (52 vs 77, p = 0.02) and better scores than open splenectomy patients in PF (90 vs 45, p = 0.05) and BP (84 vs 55.5, p = 0.01). Compared to preoperative values, open mesh hernioplasty patients showed improved scores in PF (70 vs 92.5, p = 0.03) and MH (72 vs 84, p = 0.05). Laparoscopic hernioplasty did not produce improved scores compared to either preoperative values or open hernioplasty. CONCLUSIONS: Laparoscopic surgery has demonstrably better quality-of-life outcomes than open surgery for cholecystectomy, splenectomy, and esophageal surgery. However, open hernioplasty has at least as good, if not better, health status outcomes than laparoscopic repair.     

Laparoscopic surgery in children--current possibilities and perspectives

Experience in use of different laparoscopic methods in 6046 children who needed urgent and elective surgeries are analyzed. Urgent surgeries were performed in 3292 children for acute appendicitis and it complications, acute adhesive intestinal obstruction, invagination, trauma of abdominal organs, pathological changes of Meckel diverticulum, urgent inflammatory and non-inflammatory gynecological diseases. In this group endosurgery was successful in 3120 (94.8%) patients, conversion to open surgery was necessary in 5.2% cases (172 patients). Laparoscopic cholecystectomy, splenectomy, nephrectomy, surgeries for cysts of parenchymatous organs, benign cysts and tumors of abdominal cavity and retroperitoneal space, varicocele, syndrome of unpalpable testes and abdominal cryptorchism were performed as elective surgeries in 2754 patients. Endosurgical methods to minimized number of complications (1.1% or 29 patients in the whole group), conversion to open surgery was necessary in 10 (0.4%) cases. Laparoscopic methods in many cases are the "gold standard" in elective and urgent surgery in children.

The use of laparoscopic subtotal cholecystectomy for complicated cholelithiasis

BACKGROUND: The risk of damage to the bile duct and structures in the hilum of the liver is significant when Calot's triangle cannot be safely dissected during laparoscopic cholecystectomy, and conversion to an open procedure often is performed. This is more common during emergency surgery, but may not render the procedure any easier. Traditionally, open subtotal cholecystectomy was performed, but with the advent of laparoscopic surgery, this has fallen from favor. The authors report their experience using laparoscopic subtotal cholecystectomy to avoid bile duct injury and conversion in difficult cases. METHODS: Laparoscopic subtotal cholecystectomy, performed when the cystic duct cannot be identified safely, consists of resecting the anterior wall of the gallbladder, removing all stones, and placing a large drain into Hartmann's pouch. The notes for all patients who underwent a laparoscopic subtotal cholecystectomy between 1 September 2001 and 31 December 2004 were retrospectively analyzed. RESULTS: Subtotal cholecystectomy was performed in 26 cases including 13 emergency and 13 elective procedures. The median age of the patients (15 women and 11 men) was 68 years (range, 36-86 years). The indications were severe fibrosis in 16 cases, inflammatory mass or empyema in 8 cases, and gangrenous gallbladder or perforation in 2 cases. The median postoperative inpatient stay was 5 days (range, 2-26 days). Five patients underwent postoperative endoscopic retrograde cholangiopancreatography: four for persistent biliary leak and one for a retained common bile duct stone. One patient required laparotomy for subphrenic abscess, and one patient (American Society of Anesthesiology [ASA] grade 4, presenting with biliary peritonitis) died 2 days postoperatively. One patient required a subsequent completion laparoscopic cholecystectomy for a retained gallstone. One patient had a chest infection, and two patients experienced port-site hernias. CONCLUSIONS: Laparoscopic subtotal cholecystectomy is a viable procedure during cholecystectomy in which Calot's triangle cannot be dissected. It averts the need for a laparotomy.     

The influence of laparoscopic cholecystectomy vs laparotomy on the monocyte antigen expression (HLA-DR)

It is well known that surgery significantly decrenses immune responses. Laparoscopic cholecystectomy (LC) is a so called "mini invasive" surgical presidia, and on the basis of this consideration we have investigated if and how the immune response is modified in patients after laparoscopic cholecystectomy compare to patients undergone open cholecystectomy. Immune-activity (neutrophils, total lymfocytes count, lymphocytes subpopulations, HLA-DR) was evaluated in 53 patients one day before surgery and p.o. after 1. 3 and 6 days; 26 patients underwent "open" cholecystectomy and 27 LC. One day after surgery patients with open cholecystectomy showed significant increase (p < = 0.05) of plasma neutrophils, while these parameters were almost unchanged in patients with L.C. Finally monocyte antigen HLA-DR was also reduced in patients with "open" cholecystectomy: in this group we also recorded 2 cases (7.6%) of respiratory tract infection. In conclusion LC, strongly reduces p.o. pain, hospitalization, promotes earlier recovery and return to normal activity, avoiding p.o. immunosuppression, mostly due to conservation of HLA-DR activity, with better p.o. morbidity compare to open surgery.     

One hundred consecutive laparoscopic cholecystectomies performed in a rural hospital.

Laparoscopic cholecystectomy has quickly become the treatment of choice by most surgeons for the treatment of gallstone disease. The authors reviewed their first 100 consecutive patients undergoing laparoscopic cholecystectomy at a rural hospital. Twenty-three patients had previous abdominal procedures. The open insufflation technique was used on all patients with previous abdominal operations, with the exception of those who had an appendectomy only. Operative cholangiography was performed routinely and successfully on all patients, with the exception of the first seven because of nonavailability of a cholangiocath. In 54 percent of the first two-thirds of these patients, the operation was completed in less than 1.5 hours. In contrast, 88 percent of the last one-third of the patients were operated on within the same time period. All but 9 of the 100 patients were discharged within 24 hours of their surgery. Laparoscopic cholecystectomy can be performed safely and routinely in the rural hospital setting with results similar to those expected in larger metropolitan centers.     

Outcome study of cholecystectomy during pregnancy

BACKGROUND: Several anecdotal papers suggest that laparoscopic cholecystectomy can be done safely in pregnant patients, but few patients are reported and other patients such as those who underwent laparoscopic appendectomy are often included. A larger series would help clarify the situation. METHODS: The Connecticut Laparoscopic Cholecystectomy Registry and data from the Connecticut Hospital Association (CHA) were combined to search for all cholecystectomies performed in pregnant patients from 1992 through 1996. Information on outcomes for both mother and infant was obtained through the cooperation of most of the CHA hospitals. RESULTS: Complete data were available for 46 patients, 20 laparoscopic and 26 open cases. The groups were comparable in all demographic respects except for the timing of cholecystectomy, which was performed at a mean of 18.4 +/- 6.7 weeks (range 9 to 32) of gestation for the laparoscopic and 24.8 +/- 4.7 weeks (range 14 to 35) for the open patients (P = 0.01). A maternal-fetal mortality due to intra-abdominal hemorrhage occurred in the laparoscopic group 2 weeks postoperatively. In the open group, a fetal demise occurred at 21 weeks gestation, 5 weeks postcholecystectomy. The open patients experienced 8 episodes of premature contractions compared with one one such event in the laparoscopic group (P = 0.057). CONCLUSIONS: This represents the largest reported series of laparoscopic cholecystectomy in pregnant patients. Laparoscopic cholecystectomy does not lead to increased numbers of fetal complications. Premature uterine contractions tend to occur more frequently after open cholecystectomy and when the procedure is performed later in gestation.     

The effects of laparoscopic cholecystectomy,hysterectomy, and appendectomy on nosocomial infection risks

BACKGROUND: Recent reviews of the literature have concluded that additional, well-defined studies are required to clarify the superiority of laparoscopic or open surgery. This paper presents precise estimates of nosocomial infection risks associated with laparoscopic as compared to open surgery in three procedures: cholecystectomy, appendectomy, and hysterectomy. METHODS: A retrospective analysis was performed on 11,662 admissions from 22 hospitals that have a nosocomial infection monitoring system. The Nosocomial Infection Marker (NIMtrade mark, patent pending) was used to identify nosocomial infections during hospitalization and post discharge. The dataset was limited to admissions with laparoscopic or open cholecystectomy (32.7%), appendectomy (24.0%), or hysterectomy (43.3%) and was analyzed by source of infection: urinary tract, wounds, respiratory tract, bloodstream, and others. Single- and multivariable logistic regression analyses were performed to control for the following potentially confounding variables: gender, age, type of insurance, complexity of admission on presentation, admission through the emergency department, and hospital case mix index (CMI). RESULTS: Analyses were based on 399 NIMs in 337 patients. Laparoscopic cholecystectomy and hysterectomy each reduced the overall odds of acquiring nosocomial infections by more than 50% (p < 0.01) Laparoscopic cholecystectomy and hysterectomy also resulted in statistically significantly fewer readmissions with nosocomial infections (p < 0.01). Excluding appendectomy, the odds ratio for laparoscopic versus open NIM-associated readmission was 0.346 (p < 0.01). Laparoscopic appendectomy did not significantly change the odds of acquiring nosocomial infections. CONCLUSION: As compared to open surgery, laparoscopic cholecystectomy and hysterectomy are associated with statistically significantly lower risks for nosocomial infections. For appendectomy, when comparing open versus laparoscopic approaches, no differences in the rate of nosocomial infections were detected.

Laparoscopic cholecystostomy with delayed cholecystectomy as an alternative to conversion to open procedure

Background: Acute cholecystitis carries the highest incidence of conversion from planned laparoscopic cholecystectomy to open surgery due to unclear anatomy, excessive bleeding, complications, or other technical reasons. Methods: Laparoscopic tube cholecystostomy was performed instead of immediate conversion to laparotomy in 9 patients with acute cholecystitis after unsuccessful attempts at laparoscopic dissection. Elective laparoscopic cholecystectomy was done 3 months later. Results: Following this approach eight patients were treated successfully. After 3 months the acute process had subsided sufficiently to allow a safe laparoscopic cholecystectomy. One additional patient died of acute leukemia 6 weeks after cholecystostomy. Before adopting this technique we subjected 171 patients with acute calculous cholecystitis to laparoscopic cholecystectomy; there was an 11% (19 cases) rate of conversion. Since cholecystostomy has begun to be offered as an alternative to conversion, 121 patients with acute cholecystitis have had laparoscopic cholecystectomy and only 2 cases (1.5%) have been converted to immediate open cholecystectomy. Conclusions: We recommend the alternative of performing a cholecystostomy with delayed laparoscopic cholecystectomy instead of conversion to open procedure when facing a case of acute cholecystitis not amenable to laparoscopic cholecystectomy.

Conversion in laparoscopic cholecystectomy

Laparoscopic cholecystectomy (LC) has become the gold standard in the treatment of symptomatic cholelithiasis. Some patients require conversion to open surgery and several preoperative variables have been identified as risk factors that are helpful in predicting the probability of conversion. The aim of this study was to analyze the factors that make LC difficult and determine conversion to open approach: Our study includes: 6985 cases which underwent LC and 1430 cases with open cholecystectomy, between March 1993 and April 2005 in our clinic of general surgery. The overall conversion rate was 5.1% (deliberate conversion--299 cases, conversion of necessity--62 cases). The conversion rate has decreased from 17.5% in 1993 to 3.2% in recent years. The most conversion happen after a simple inspection or a minimal dissection caused by the existence of perforation (105 cases), the discovery of a difficult anatomic situation (63 cases) or of another pathology (14 cases); more rarely, the conversion was necessary in the principal time, doing to hemorrhage (26 cases), impossible dissection (41 cases), visceral injury (1 case) or even at the end of the operation, doing to hemorrhage, loss piece or stone (10 cases), and other situations (101 cases). Significant predictors of conversion were acute cholecystitis , choledocholithiasis, past history of acute cholecystitis, male gender, gall bladder wall thickness exceeding 6 mm. In conclusion, based on our experience, we suggest limiting OC to patients with proven contraindications to LC (i.e., Mirizzi syndrome or systemic illness incompatible with general anesthesia or pneumoperitoneum), attempting LC in all other cases. Decision to convert to open approach is a proven of surgical maturity. Conversion must be decided from the beginning, in the moment of the recognition of a difficult situation and not after the occurrence of a complication.

Tube Cholecystostomy Before Cholecystectomy for the Treatment of Acute Cholecystitis

Methods:This study was a retrospective chart review of patients who underwent tube cholecystostomy from July 1, 2005, to July 1, 2012.Results:During the study period, 82 patients underwent 125 cholecystostomy tube placements. Four patients (5%) died during the year after tube placement. The mean hospital length of stay for survivors was 8.8 days (range, 1–59 days). Twenty-eight patients (34%) required at least 1 additional percutaneous procedure (range, 1–6) for gallbladder drainage. Twenty-nine patients (34%) ultimately underwent cholecystectomy. Surgery was performed a mean of 7 weeks after cholecystostomy tube placement. Laparoscopic cholecystectomy was attempted in 25 operative patients but required conversion to an open approach in 8 cases (32%). In another 4 cases, planned open cholecystectomy was performed. Major postoperative complications were limited to 2 patients with postoperative common bile duct obstruction requiring endoscopic retrograde cholangiopancreatography, 1 patient requiring a return to the operating room for hemoperitoneum, and 2 patients with bile leak from the cystic duct stump.Conclusions:In high-risk patients receiving cholecystostomy tubes for acute cholecystitis, only about one third will undergo surgical cholecystectomy. Laparoscopic cholecystectomy performed in this circumstance has a higher rate of conversion to open surgery and higher hepatobiliary morbidity rate.
