Emergency hernia repair in the elderly: multivariate analysis of morbidity and mortality from an Italian registry.

PURPOSE: The incidence of inguinal hernia is higher in elderly because of aging-related diseases like prostatism, bronchitis, collagen laxity. A conservative management is common in elderly to reduce surgery-related risks, however watchful waiting can expose to obstruction and strangulation. The aim of the present study was to assess the impact of emergency surgery in a large series of elderly with complicated groin hernia and to identify the independent risk factors for postoperative morbidity and mortality. The predictive performance of prognostic risk scores has been also assessed. METHODS: This is a prospective observational study carried out between January 2017 and June 2018 in elderly patients who underwent emergency surgery for complicated hernia in 38 Italian hospitals. Pre-operative, surgical and postoperative data were recorded for each patient. ASA score, Charlson's comorbidity index, P-POSSUM and CR-POSSUM were assessed. RESULTS: 259 patients were recruited, mean age was 80 years. A direct repair without mesh was performed in 62 (23.9%) patients. Explorative laparotomy was performed in 56 (21.6%) patients and bowel resection was necessary in 44 (17%). Mortality occurred in seven (2.8%) patients. Fifty-five (21.2%) patients developed complications, 12 of whom had a major one. At univariate and multivariate analyses, Charlson's comorbidity index ≥ 6, altered mental status, and need for laparotomy were associated with major complications and mortality CONCLUSION: Emergency surgery for complicated hernia is burdened by high morbidity and mortality in elderly patients. Preoperative comorbidity played a pivotal role in predicting complications and mortality and therefore Charlson's comorbidity index could be adopted to select patients for elective operation.

High-Performance Porous Ionic Liquids for Low-Pressure CO2 Capture*.

Porous ionic liquids are non-volatile, versatile materials that associate porosity and fluidity. New porous ionic liquids, based on the ZIF-8 metal-organic framework and on phosphonium acetate or levulinate salts, were prepared and show an increased capacity to absorb carbon dioxide at low pressures. Porous suspensions based on phosphonium levulinate ionic liquid absorb reversibly 103 % more carbon dioxide per mass than pure ZIF-8 at 1 bar and 303 K. We show how the rational combination of MOFs with ionic liquids can greatly enhance low pressure CO2 absorption, paving the way towards a new generation of high-performance, readily available liquid materials for effective low pressure carbon capture.

How Does the Addition of a Third Ion Affect the Molecular Interactions and the Thermodynamic Properties of Acetate-Based Ionic Liquids?

The effect of the addition of a third ion to the ionic liquid 1-butyl-3-methylimidazolium acetate [C4C1Im][OAc] was studied through the measurement of the enthalpy of mixing and of the excess molar volume of its mixtures with 1-butyl-3-methylimidazolium trifluoroacetate [C4C1Im][CF3CO2], 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [C4C1Im][NTf2], and tetrabutylphosphonium acetate [P4444][OAc]. Negative enthalpies of mixing (ΔmixH < 0) and positive excess molar volumes (VE > 0) were observed in all cases. The infrared and NMR studies of the pure ionic liquids and their mixtures show that the presence of a third ion with a weaker affinity with the common counterion contributes to prevailing the more favorable hydrogen-bond, herein always between the imidazolium cation and the acetate anion. Both radial and spatial distribution functions calculated by molecular simulation confirm this behavior. The remarkable enhancement of the viscosities of the [C4C1Im][OAc] + [P4444][OAc] mixtures could be discussed in light of the calculated friction coefficients.

Can the tricyanomethanide anion improve CO2 absorption by acetate-based ionic liquids?

Carbon dioxide absorption by mixtures of two ionic liquids with a common cation-1-butyl-3-methylimidazolium acetate, [C4C1Im][OAc], and 1-butyl-3-methylimidazolium tricyanomethanide, [C4C1Im][C(CN)3]-was determined experimentally at pressures below atmospheric pressure as a function of temperature between 303 K and 343 K, and at 303 K as a function of pressure up to 10 bar. It is observed that the absorption of carbon dioxide decreases with increasing tricyanomethanide anion concentration and with increasing temperature, showing a maximum of 0.4 mole fraction of carbon dioxide in pure [C4C1Im][OAc] at 303 K. At this temperature, the CO2 absorption in the mixtures [C4C1Im][OAc](1-x)[C(CN)3]x is approximately the mole-fraction average of that in the pure ionic liquids. By applying an appropriate thermodynamic treatment, after identification of the species in solution, it was possible to calculate both the equilibrium constant, Keq, and Henry's law constant, KH, in the different mixtures studied thus obtaining an insight into the relative contribution of chemical and physical absorption of the gas. It is shown that chemical sorption proceeds through a 1 : 2 stoichiometry between CO2 and acetate-based ionic liquid. The presence of the C(CN)3- anion does not significantly affect the chemical reaction of the gas with the solvent (Keq = 75 ± 2 at 303 K) but leads to lower Henry's law constants (from KH = 77.8 ± 0.6 bar to KH = 49.5 ± 0.5 bar at 303 K), thus pointing towards larger physical absorption of the gas. The tricyanomethanide anion considerably improves the mass transfer by increasing the fluidity of the absorbent as proven by the larger diffusivities of all the ions when the concentration of the C(CN)3- anion increases in the mixtures.

Tailoring the properties of acetate-based ionic liquids using the tricyanomethanide anion.

The equilibrium and transport properties of mixtures of two ionic liquids - [C4C1Im][OAc] and [C4C1Im][C(CN)3] - were determined and interpreted at the molecular level using vibration spectroscopy, NMR and molecular dynamics simulation. The non-ideality of the mixtures [C4C1Im][OAc](1-x)[C(CN)3]x was characterized by V(E) = +0.28 cm(3) mol(-1) (293 K, x = 0.65) and H(E) = -2.2 kJ mol(-1) for x = 0.5. These values could be explained by a rearrangement of the hydrogen-bond network of the mixture that favours the interaction of the acetate anion with the imidazolium cation at position C2. The dynamic properties of the mixture are also dramatically influenced by the composition with a decrease of the viscosity and an increase of self-diffusion coefficients of the ions when the amount of tricyanomethanide anion increases in the mixture.

[Pancreatic anastomotic fistula after pancreaticoduodenectomy: incidence, significance and treatment]. / La fistola anastomotica pancreatica dopo duodenocefalopancreasectomia: incidenza, significato e trattamento.

The Authors reviewed the complications, and outcomes in a consecutives series of 97 patients undergoing pancreaticoduodenectomy. The clinical leak rate in this series was 21.8%. There was a difference in the pancreatic leak rate in those patients who underwent pancreatic ductal closure or end to end pancreaticojejunal invagination compared with end to side pancreaticojejunal anastomosis. The postoperative complication rate was 41.8% and the most common complications were pancreatic fistula. 9 deaths occurred in hospital or within 30 days from operation. Univariate and multivariate analysis revealed that operative technique, the pathological status of the pancreatic remnant, and mayor complications were the significant risk factors for the development of pancreatic anastomotic leak. In the 2000s pancreatic leak remains a potentially lethal problem. After pancreaticoduodenectomy, pancreatic remnant management by end to side pancreaticojejunostomy appeared safe in low-risk patients. Morbidity was greatest after pancreatic duct closure without anastomosis.

[Carcinoma of the male breast. Prognostic factors and outcome of surgical treatment]. / Il carcinoma della mammella nell'uomo. Fattori prognostici e criteri di trattamento.

A retrospective study was made on 18 male patients with breast carcinoma treated at the Department of Surgery "Pietro Valdoni" of the University "La Sapienza" of Rome, Medical School. Demographics, pathology, stages, and treatment were determined from clinical reports. All patients but one underwent modified radical mastectomy. The length of follow up averaged 57.5 months. Five years actuarial survival rate was 62%. In the current study the Authors suggest that the clinical, prognostic and treatment features of breast carcinoma in men are similar to those reported in literature for post-menopausal women.

[Ambulatory closed surgery for the treatment of pilonidal sinus]. / Il trattamento chirurgico ambulatoriale del sinus pilonidalis con tecnica chiusa.

Pilonidal disease (PD) is a common chronic disorder of the sacrococcygeal region afflecting young people. Despite several methods for treating PD have been described, the management remains controversial. Recent reports have advocated different surgical approaches such as open or closed technique, but recurrence plagues all forms of therapy. We conducted this case review to evaluate the validity of an outpatient closed technique in the treatment of chronic pilonidal disease. Between January 1997 and July 1999, 65 consecutive patients with quiescent chronic PD were electively treated by surgical excision of the cyst and primary closure. There were 47 men (72%) and 18 women (28%) in this study. Patients ranged in age from 14 to 47 years, the average age being 21 years. The median healing time was 8 days and the median time to return to full work was 20 days (range 10-25). Infection and recurrence rates were 1.5% and 4.6% respectively. There was no correlation among recurrence rate, postoperative infection, or prior surgery. Cyst excision and primary closure is a safe, low cost operation with a very high long-term success rate and a negligible rate of complications. It can successfully be performed under local anaesthesia in an outpatient facility.

Late development of bile duct cancer in patients who had biliary-enteric drainage for benign disease: a follow-up study of more than 1,000 patients.

OBJECTIVE: To evaluate the correlation between biliary-enteric surgical drainage and the late development of cholangiocarcinoma of the biliary tract. SUMMARY BACKGROUND DATA: In patients with biliary-enteric drainage, reflux of intestinal contents into the bile duct may occur and cause cholangitis, which is regarded as the most serious complication of these procedures. Lithiasis of the biliary tract and a previous biliary-enteric anastomosis have both been suggested to favor the late onset of cholangiocarcinoma. METHODS: Consecutive patients (n = 1,003) undergoing three different procedures of biliary-enteric anastomosis (transduodenal sphincteroplasty, choledochoduodenostomy, and hepaticojejunostomy) between 1967 and 1997 were included in this study. The postoperative clinical course and long-term outcome were evaluated by a retrospective review of the hospital records and follow-up. Mean follow-up was 129.6 months. RESULTS: Fifty-five (5.5%) cases of primary bile duct cancer were found among the 1,003 patients at intervals of 132 to 218 months from biliary-enteric anastomosis. The incidence of cholangiocarcinoma in the three groups was 5.8% in transduodenal sphincteroplasty patients, 7.6% in choledochoduodenostomy patients, and 1.9% in hepaticojejunostomy patients. The incidence of malignancy related to the different underlying diagnosis was 5.9%, 7.2%, and 1.9% in patients with choledocholithiasis, sphincter of Oddi stenosis, and postoperative benign stricture, respectively. Although only one patient who developed cholangiocarcinoma had previous concurrent lithiasis of the biliary tract, 40 patients had experienced mostly severe, recurrent cholangitis. No case of malignancy occurred in patients scored as having no cholangitis in the early and long-term postoperative outcome. Univariate and multivariate analyses have shown the presence of cholangitis as the only factor affecting the incidence of cholangiocarcinoma. CONCLUSIONS: Chronic inflammatory changes consequent to biliary-enteric drainage should be closely monitored for the late development of biliary tract malignancies.

Clinical significance of normobasemia in early post-operative outcome of hepatic resections.

BACKGROUND: Major hepatic resections are usually followed by acid-base unbalance. Adjustment of the acid-base disorders is considered central when dealing with these critical patients and normobasemia is thought to be a favourable prognostic factor when occurring in the immediate postoperative outcome after major surgery. The present study was undertaken to investigate the influence of acid base balance on the early outcome after hepatic resection. METHODS: A series of fifty-seven cirrhotic patients was submitted to liver resection for hepatocellular carcinoma. Forty-eight patients experienced an uneventful early postoperative outcome (CTR group). Nine died in the postoperative course (HD group). In all patients pulmonary, renal and hepatic functions were monitored pre- and postoperatively. The pH values were detected daily preoperatively and in the course of the first three days after hepatic resection. In the same days acid base balance and arterial ketone body ratio were assessed on arterial blood samples. Data were collected in a data base and statistical analysis was performed. RESULTS: A significantly higher metabolic alkalosis was found to characterize the first and second postoperative days (POD1 and POD2) in the CTR group (pH 7.43+/-0.007 vs pH 7.33+/-0.001; pH 7.45+/-0.006 vs pH 7.35+/-0.009; p<0.05). Lower values of pH and an associated impaired energetic status of the liver were found to characterise the postoperative course of the poor prognosis patients. At POD1 AKBR decreased in both groups but while recovering at POD2 in patients of CTR group maintained significantly lower values in HD group (AKBR 1+/-0.3 vs 0.5+/-0.2; p<0.01). A lower energetic status of the liver is associated with an inadequate tricarboxylic acid cycle and is responsible for an impaired production of HCO3-. CONCLUSIONS: Apparent normobasemia is then expressive of liver failure leading to poor postoperative outcome.

The influence of somatostatin on bacterial translocation.

BACKGROUND: Bacterial translocation is defined as the passage of bacteria from the gastrointestinal tract to extraintestinal sites mostly as a consequence of the loss of the gut barrier function. Somatostatin and octreotide, exerting many inhibitory effects on the gastrointestinal tract, have been evidenced to promote bacterial translocation. DESIGN: experimental research. SETTING: University teaching Hospital. INTERVENTIONS: Sixteen pigs forming the study group received 25 mg/kg of octreotide twice a day for ten days. A control group (n=16) received an equal volume of saline solution for the same period. All animals were sacrificed and tissue cultures were obtained from mesenteric lymph nodes (MLN), liver and spleen. Portal venous and central venous blood samples were also withdrawn for culture. RESULTS: In the octreotide group, cultures were positive for bacteria in 43.7% (7/16) of animals. Viable bacteria were recovered from MLN, liver and spleen. Portal and systemic blood cultures showed no growth of bacteria. The mean value of bacterial detection in MLN, liver and spleen was 196+/-13 CFU/g, 190+/-26 CFU/g, and 173+/-0 CFU/g, respectively. P value was not statistically significant. Bacterial translocation did not occur in the animals of the control group. Fisher s exact test revealed a statistically significant difference (p<0.007) between the two groups regarding bacterial translocation to MLN. CONCLUSIONS: The administration of octreotide is followed by a conspicuous increase in bacterial translocation in pigs. Further clinical studies are needed to demonstrate similar effects on humans.

Total mesorectal excision and low rectal anastomosis for the treatment of rectal cancer and prevention of pelvic recurrences.

HYPOTHESIS: Total mesorectal excision lowers the rate of pelvic recurrence and positively affects the survival after surgical treatment of rectal cancer. DESIGN: Case series. SETTING: Tertiary care university hospital. PATIENTS: Fifty-three consecutive patients were admitted with curative intent to surgery at the First Department of Surgery of the University of Rome "La Sapienza," Rome, Italy, with diagnoses of rectal carcinoma. The mean follow-up was 68.9 months; follow-up was complete for all patients who entered the trial. INTERVENTIONS: Low anterior resection and total mesorectal excision were performed in all cases, regardless of the location of the rectal cancer. A straight mechanical colorectal anastomosis was performed on a rectal stump, never exceeding 5 cm. No kind of adjuvant therapy was given. Mesorectum and open rectum were studied by serial transverse section at 5-mm intervals. A search for depth of penetration and distal intramural extension of the tumor was made. Lymph nodes were detected by clearing method, and nodal metastases (NM) and nonnodal metastases (NNM) were recorded as situated proximally, distally, or at the level of the tumor. RESULTS: There was no postoperative mortality. Clinical and radiologic leaks occurred in 2 and 4 patients, respectively. Mean disease-free survival was 65.9 months. Pelvic recurrence occurred in 5 patients (9%). Overall 5-year survival rate was 75%. Involvement of mesorectum by NM and NNM was detected in 27 and 24 cases, respectively. Both NM and NNM were found to be distal in 33% and 40% of cases, respectively. CONCLUSIONS: Microscopic spread to the distal mesorectum may exceed the intramural spread of rectal cancer. Failure to perform total mesorectal excision leaves a potentially residual disease in the distal mesorectum, thus predisposing the patient to pelvic recurrence.

Prospective evaluation of omentoplasty in preventing leakage of colorectal anastomosis.

PURPOSE: The aim of this study was to investigate the role of omentoplasty, by means of intact omentum, in preventing anastomotic leakages after rectal resection. METHODS: Between 1992 and 1997 a total of 112 patients (64 males) with a mean age of 64.7 (range, 39-83) years were randomly assigned to undergo omentoplasty (Group A) or not (Group B) to reinforce the colorectal anastomosis after anterior resection for rectal cancer. The primary end point was anastomotic leakage; the secondary end point included morbidity and mortality related to omentoplasty. RESULTS: The two groups were comparable in terms of preoperative and intraoperative characteristics. Staple-ring disruption at plain abdominal radiographs was detected in seven instances in Group A and in ten in Group B patients (P = not significant). Two leakages were evident clinically in Group A and seven in Group B (P < 0.05). Three leaks were documented radiologically in Group A and eight in Group B (P = not significant). No complications related to omentoplasty were observed in Group A. There were two repeat operations for anastomotic leakage in Group B. At followup, one stricture developed in Group A and three in Group B (P = not significant) CONCLUSIONS: Despite a similar incidence of staple-ring defects, a strikingly lower rate of clinically and radiologically detected leaks developed in patients submitted to omentoplasty. Although not affecting the incidence of anastomotic disruption, omentoplasty seems to contain the severity of anastomotic leakage.

Management of benign biliary strictures: biliary enteric anastomosis vs endoscopic stenting.

HYPOTHESIS: Although advances in endoscopic procedures have provided alternative options for relieving biliary obstructions, the overall chance of cure for patients with benign biliary stricture is the same using surgical or endoscopic treatment. DESIGN: Case-control study. SETTING: Tertiary care university hospital. PATIENTS: Of 163 patients referred for treatment with diagnoses of benign strictures of the common bile duct between January 1, 1975, and July 1, 1998, we studied 42 patients with postcholecystectomy stricture and a follow-up longer than 60 months. Twenty of these patients were treated with endoscopic stenting and 22 with surgery (hepaticojejunostomy, choledochojejunostomy, or intrahepatic cholangiojejunostomy). MAIN OUTCOME MEASURES: Postoperative mortality and morbidity and long-term outcome. The rate of restenosis was also determined. RESULTS: Morbidity occurred more frequently in patients treated with endoscopic procedures than with surgical ones (9 vs 2; P = .34). Hospital mortality was 0%. Surgery achieved excellent or good long-term outcome in 17 of 22 patients. Endoscopic biliary stenting was successful in 16 of 20 patients. Overall, excellent or good outcomes were achieved in 34 patients (81%). CONCLUSION: The ability to achieve steady, long-term results confirms hepaticojejunostomy as the best procedure in the treatment of benign biliary strictures, even if endoscopic procedures are gaining a new role in the treatment of a greater number of patients.

The need for antibiotic prophylaxis in elective laparoscopic cholecystectomy: a prospective randomized study.

HYPOTHESIS: The need for antibiotic treatment when performing elective laparoscopic cholecystectomy may not be as important as it is thought. This study assesses the real efficacy of antibiotic prophylaxis in elective laparoscopic cholecystectomy with respect to the postoperative infection rate. DESIGN: A prospective randomized study on the routine use of antibiotic prophylaxis in laparoscopic cholecystectomy. SETTING: University teaching hospital, La Sapienza, Italy. PATIENTS: Eighty-four patients randomly placed into 2 groups (A [n = 44] and B [n = 40]) immediately before undergoing laparoscopic cholecystectomy. METHODS: Before anesthesia was administered, group A received intravenously 2 g of cefotaxime sodium diluted in 100 mL of isotonic sodium chloride solution; group B, 10 mL of isotonic sodium chloride solution in 100 mL of saline. A gallbladder bile sample for culture was withdrawn intraoperatively from all patients. In both groups, age, sex, weight, duration of surgery, presence of diabetes, American Society of Anesthesiologists patient classification score, preoperative autologous blood donation, antibiotic administration, intraoperative gallbladder rupture, findings from bile culture positive for bacteria, episodes of colic within 30 days before surgery, length of postoperative hospital stay, and number of septic complications were recorded. All data were correlated by univariate and multivariate analyses with the onset of septic phenomena. RESULTS: In group A, 3 cases of wound infection, 1 case of subhepatic abscess from bile leakage, and 1 case of urinary tract infection were observed; group B, 4 cases of wound infection, 1 case of bronchopneumonia, and 2 cases of urinary tract infection. Comparison of data showed no statistically significant difference between the groups. Findings from bile examination in patients with sepsis complications were positive in 5 patients in group A and in 6 in group B (P = .91). Multivariate analysis showed diabetes mellitus and colic episodes within 30 days before surgery as independent factors significantly associated to the onset of infectious complications. CONCLUSIONS: In elective laparoscopic cholecystectomy, antibiotic treatment did not seem to affect the incidence and severity of infections or the degree of bile contamination.

[Layered and mass sutures in the closure of median laparotomies]. / Sutura per strati e in piano unico nella chiusura di laparotomie mediane.

A retrospective comparison of 2830 patients with midline abdominal incision closures was made. Dehiscences, infections, hernias were compared examining continuous mass closures (group A) versus interrupted mass closures (group B) and interrupted layered sutures (group C). The three groups were well matched for known risk factors for each of the above complications. Mass closures produced a significant higher number of infections (p = 0.0006) and hernias (p = 0.0001). There was no significant difference in the rate of dehiscences in the three suture groups (p = 0.07). A significant correlation was found in all three groups between the incidence of infections and that of outcoming incisional hernias. In the current study layered closure of the of the midline abdominal wounds yielded better results when compared with both running mass and interrupted mass closures. The knowledge of these findings might help when choosing the procedure to close a midline abdominal incision.

[Anterior approach and simultaneous tension-free repair of bilateral inguinal hernia under local anesthesia]. / Riparazione simultanea delle ernie inguinali bilaterali con tecnica tension free per via anteriore in anestesia locale.

An analysis of prospectively collected data of 56 patients submitted to bilateral hernia repair is reported. Simultaneous repair was performed in 32 patients (Group S) while a sequential repair in 24 (Group D). Mean operating time was longer for the combination of two sequential repairs than for simultaneous repair (132 min +/- 8.9 vs 123 min +/- 11, p < 0.001). Mean hospital stay was similar in unilateral and bilateral repairs (18.0 hrs +/- 4 vs 21.2 hrs +/- 3.4, p = ns). Ther were no difference in complications between the two groups. Time taken to return to full activity was nearly double in the combination of two sequential repairs than in simultaneous repair (25 days, sd +/- 4 vs 16 days +/- 3, p < 0.001), while postoperative analgesia requirements were similar. The Authors conclude that bilateral simultaneous anterior tension free repair under local anesthesia is the treatment of choice in case of bilateral inguinal hernias.

Rectal cancer and inguinal metastases: prognostic role and therapeutic indications.

PURPOSE: The aim of this study was to analyze the outcome of patients with inguinal metastases from rectal cancer. METHODS: Clinical records and data concerning the follow-up of patients referred to our institution for rectal cancer were reviewed retrospectively. Patients were divided into four groups based on the time interval between first admission and appearance of inguinal metastases. All patients were followed up until death. Age, gender, tumor stage, and disease-free intervals were examined to assess their impact on prognosis. RESULTS: Patients with rectal adenocarcinoma (N = 863) were observed from 1965 to 1990. In 21 patients the biopsy-proven diagnosis was of adenocarcinoma metastasizing to the inguinal nodes. Of these 21 patients, 15 were males. The mean age was 69.3 (range, 52-84) years. Primary lesions were exclusively T3, and no patient was found to have negative mesorectal lymph nodes. Survival from the time of diagnosis of inguinal metastases ranged from 2 to 42 (mean, 14.8) months. Patients with a disease-free interval of 12 months or more had a statistically significant longer survival time. CONCLUSIONS: Inguinal lymph-node metastases from rectal carcinoma occur as a consequence of locally advanced primary tumors or recurrent pelvic malignancy. Because of the frequency of distant metastases and the consequent poor prognosis, only systemic chemotherapy and radiotherapy should be considered. In patients who seem to be free of local recurrence and distant metastases, groin dissection is suggested for debulking and control of disease.

[The so-called postcholecystectomy syndrome after laparoscopic intervention]. / La cosiddetta sindrome postcolecistectomia dopo interventi per via laparoscopica.

Preoperative symptoms have been found to persist in up to 30% of patients after open cholecystectomy. No data exists about the influence of laparoscopic cholecystectomy on symptoms. A group of 109 elective patients who had undergone at least 12 months previously laparoscopic cholecystectomy were retrospectively studied. Pre- and postoperative symptoms were compared and patients satisfaction graded from 1 (excellent) to 5 (worst). More than two symptoms were present preoperatively in all patients. Postoperatively 75 patients were absolutely symptomless. 9 patients complained of only one symptom, and 25 patients continued to have two or more symptoms. The mean time to return to full activity did not correlate with the number of postoperative symptoms. Most patients (75) considered the procedure completely successful while only 6 were no better off postoperatively. The incidence of symptoms after laparoscopic and laparotomic cholecystectomy is similar. The patients should be advised that the presence of preoperative symptoms are not necessarily caused by gallstones and that cholecystectomy might be followed by the persistence of symptoms.
