Laparoscopic repair of a Morgagni hernia: report of a case and review of the literature.

A case is reported of an 85-year-old woman with subacute intestinal obstruction due to a large Morgagni hernia containing the transverse colon. The repair was carried out laparoscopically without a mesh. The procedure lasted 45 min, and the patient was discharged after 4 days. According to the literature, mini-invasive repair of a Morgagni hernia can be performed easily and without complications. In only few cases was a mesh necessary. The Morgagni hernia must be considered a clear indication for laparoscopic surgery, which should be offered as the first approach to this disease.

Prospective clinical evaluation and follow-up of a cohort of consecutive VT/VF patients, using a staged-care protocol, including coronary arteriography, programmed electrical stimulation and cardiac surgery.

The prospective evaluation and follow-up of 39 consecutive subjects with VT/VF, 6 of whom, with cardiac arrest (CA), are reported. Patients were enrolled in a specific staged-care approach protocol, which included coronary arteriography (CAR) and ventriculography (VC), in order to exclude the need of cardiac surgery, including coronary artery bypass graft (CABG), with and without left ventricular aneurysmectomy (LVA). The protocol included inducibility of VT/VF, which was verified by programmed electrical stimulation (PES) in control conditions and after antiarrhythmic therapy (ADT), to assess persistent inducibility and mainly to verify the hemodynamic sequelae of VT. VT that showed poor hemodynamic tolerance was treated with ICD, while well-tolerated VT was treated by ADT or ablation when indicated. Furthermore, PES was obtained after surgical procedures. As a first step, the patients were assigned to receive amiodarone (AMIO) (200-400 mg/daily) in the presence of EF% < 30% or contraindication to sotalol, (Group A), or sotalol (SOT) (80-140 mg/daily) in the presence of EF > or = 31%. (Group C). Conversely, in case of recurrences, patients were assigned to receive AMIO (200-300 mg/daily) plus metoprolol (MET) (20-100 mg/daily), (Group B) or, in case of intolerance to beta-blockers, to AMIO plus mexiletine (MEX) (200 mg/daily) (Group D). The four groups were similar for the type of VA, with recurrent ventricular tachycardia (RVT) being the most frequent one. The most frequent underlying cardiac disease of VA in this study was post-AMI CAD, with a rate of over 60% in all four groups. Single- and two-vessel lesions were found at CAR in various patients in all four groups, in 5/13 (38%) in Group A, in 8/14 (57%) in Group B, in 5/7 (71%) in Group C, and in 3/5 (60%) in Group D. Cardiac surgery was performed in a similar and limited number of patients in all four groups, in 4/13 (30%) in Group A, in 4/14 (35%) in Group B, in 2/7 (28%) in Group C, and in 2/5 (40%) in Group D. In 8/39 (20.5%) of the patients who underwent CABG, there was no operative or late mortality; 4/39 (10.2%) received CABG and LVA, and two died. For the amiodarone plus metoprolol and sotalol patients only, PES showed a lower residual inducibility, in comparison to the amiodarone and amiodarone + mexiletine groups. In the entire group, 7 out of 26 (27%) were still inducibile at PES while in 19/26 (64%) of the patients, an apparently effective treatment could be found, documenting the relative usefulness of PES. Recurrence rate was the highest in the amiodarone + mexiletine group and in patients with previous CA. Our data show the potential utility and limitations of ADT, even using the most effective antiarrhythmic drugs and association of drugs, mainly because of the high recurrence rate of VT observed in the present study, even in non-inducible patients [14/39 (36%)]. In conclusion, in a prospective and staged-care approach protocol of management of VT/VF patients, only a few patients with VT/VF benefited from cardiac surgery. PES could still play a role in the evaluation of the most effective ADT. Amiodarone + metoprolol seems to be the most effective ADT in these patients. Nevertheless, a high recurrence rate was observed in this patient population, even with an aggressive protocol, in the short follow-up period of 12 +/- 8 months, confirming recent data on the superiority of ICD to ADT, in patients with frequent recurrences or hemodynamically poorly-tolerated VT. In these patients, ICD therapy should definitively be preferred to ADT.

In vitro evaluation of the cytotoxic, hemolytic and clastogenic activities of Rhizostoma pulmo toxin(s).

Cytotoxic, hemolytic and clastogenic activities of Rhizostoma pulmo toxin(s) contained in the jelly tissue free of nematocysts were investigated in mammalian cells with in vitro procedures. At the concentration of 37.6 microg/ml the tissue protein produced the death of 50% V79 cells; a similar potency was observed in terms of hemolytic activity. The toxin(s) was not clastogenic for human lymphocytes in culture at the concentration of 5 microg/ml.

Suspected appendicitis in situs inversus totalis: an indication for a laparoscopic approach.

We report a case of acute appendicitis in situs inversus treated by laparoscopy. In our opinion, diagnostic laparoscopy is indicated if acute appendicitis is suspected in a patient with situs inversus totalis, either because the pain can be referred to the right iliac fossa in about 50% of the patients, or because the incision in open surgery cannot be sufficient to allow complete exploration of the abdomen. The operation can then be carried out laparoscopically if possible; if not, an appropriate surgical incision can be made.

Reliability of ultrasounds in detecting common bile duct stones before biliary surgery. A retrospective analysis.

UNLABELLED: The aim of this study is to evaluate the diagnostic benefit of US in the preoperative screening for CBD stones in patients submitted to surgery for biliary lithiasis. MATERIALS AND METHODS: We analyzed the data of 135 patients admitted for biliary lithiasis, jaundice or biliary pancreatitis in the last three years. Mean age was 63 years (54.8% females), 48% of the cases had an urgent admission. US of the liver and biliary ducts was the first examination performed and the patients were divided in 2 groups on the bases of the results: those with the diameter of the CBD < 1 cm (101 pts-group A) and those with a diameter > 1 cm (34 pts-group B). RESULTS: In group A were subsequently performed: 35 IV cholangiographies (6 showed CBD stones, 1 was a false negative for CBD stones), 15 intraoperative (I.O.) cholangiographies (1 positive for CBD stones), 9 ERCP for jaundice or pancreatitis (2 positive for CBD stones). The incidence of CBD stones was 8.9% in this group. In group B were performed: 7 IV cholangiographies (2 showed CBD stones), 12 I.O. cholangiographies (6 showed CBD stones), 10 ERCP for jaundice or pancreatitis (7 showed CBD stones). The incidence of CBD stones was 44% in this group. CBD stones were detected by US in 2 cases (22%) in group A and in 6 cases (40%) in group B. CONCLUSIONS: In our patients there is a relatively high incidence of CBD stones (8.9%) in spite of a normal CBD at US. Considering that the minimally invasive approach for the gallbladder stones is becoming the "gold standard" and the laparoscopic treatment of the CBD stones is not widely diffused, it is important to know the presence of CBD stones before surgery. With this in mind US does not seem to be a reliable diagnostic tool and we suggest that before surgery an IV cholangiography (sensitivity > 95% in our experience) should be performed together with US and ERCP in selected cases. Moreover this could reduce the number of preoperative ERCP leaving the possibility to treat more selectively by endoscopic papillosphincterotomy the patients with CBD stones before laparoscopic cholecystectomy.

[Laparoscopic adrenalectomy. A critical review of the literature].

Open adrenalectomy needs surgical incisions often large and traumatic, with a not negligible morbidity. Laparoscopic adrenalectomy, according to the experiences reported in the literature, certainly initial, but nevertheless considerable, seems to offer a sound option and will probably become one of the strongest indications of the minimal-access surgery of the retroperitoneal space. Operative times are certainly longer initially than in open surgery but morbidity is very low and mortality almost nil. The authors make a review of the literature about laparoscopic adrenalectomy with about 400 operations collected, analyzing the results and the technical details. The collected data support the conclusion that the adrenal pathology, with the exception of the malignant tumors, will be treated in the future mainly laparoscopically. Even the size of the tumor, in case of a not malignant mass, can not be considered probably a true contraindication.

[Laparoscopic splenectomy: comments on the surgical technic].

The authors describe the technique applied in their first case of laparoscopic splenectomy, in a patient with idiopathic thrombocytopenic purpura. Different technical approaches adopted by other surgeons are referred and discussed. The laparoscopic approach to splenectomy seems safe and allows the patients to re return to normal activity sooner than the "open" technique. Laparoscopy should be considered in patients who require splenectomy for benign disease.

[Laparoscopic cholecystectomy: a need to drain?].

The authors summarize their experience about the use of a drain after laparoscopic cholecystectomy. After an initial period without drainage, the drain is now routinely used by the Authors and their clinical experience suggests that it is probably very useful during the initial training and probably prevented some reoperations when biliary leakage and/or small hemorrhage from the gallbladder bed were present. Therefore the opinion of the Authors is to always drain after laparoscopic cholecystectomy, specially during the initial experience or after a particularly difficult operation.

Vital staining of oesophagus in patients with head and neck cancer: still a worthwhile procedure.

One hundred three patients with upper aerodigestive cancer were consecutively submitted to upper GI endoscopy with vital staining (Toluidine Blue 1%) of the oesophagus. The aim of the study was not only to confirm the prevalence of synchronous or metachronous tumour but also to verify the usefulness of the vital stain compared to simple endoscopy. Staining was positive in 29 patients (28.1%) for oesophagitis, leukoplakia, Barrett's oesophagus and 3 oesophageal neoplasms (2.9%), two of them unsuspected at endoscopy. We did not observe false positives while 13 cases (13/29-44.8%) were considered normal at endoscopy. Five cases with some endoscopic abnormality of the mucosa did not stain and were considered false negatives. Specificity of the method was 100%, sensibility 85.2%. The recognition of dysplastic changes and neoplasms not suspected at endoscopy should recommend in our opinion the use of vital staining of oesophagus in high-risk groups.

[Laparoscopic cholecystectomy: analysis of the first 50 cases].

The initial experience of laparoscopic cholecystectomy (50 cases), has been analyzed: the incidence of laparotomy, the complication rate and the postoperative course are in agreement with the data reported in the literature: however in the second half of the cases there was a striking reduction of laparotomies and complications while the postoperative course remained unchanged. Laparoscopic cholecystectomy is a relatively easy technique which requires nevertheless a didactic training and a constant application. On these premises the results can be good and explain the progressive diffusion of the techniques together with the development of the mini-invasive surgery.

[Prevention of the 1st bleeding of esophageal varices: review of the literature and clinical experience].

The authors present a review of the literature on prophylactic sclerosis of esophageal varices in cirrhotics, taking as a starting point their personal experience. The natural history of varices and the criteria of their hemorrhagic risk are described; moreover are presented the results of the most important controlled studies of prophylactic surgery, sclerosis and beta-blocking drugs. In spite of the rather encouraging results after sclerosis at the long-term follow-up and the promising aspects of beta-blocking agents, it is not felt to recommend, according to the literature, a routine application of prophylactic sclerosis, a procedure which should be reserved to leading centers in controlled studies.

Perioperative management of diabetic subjects. Subcutaneous versus intravenous insulin administration during glucose-potassium infusion.

The purpose of this study was to validate methods for the perioperative management of diabetic patients that meet the prerequisites of simplicity, applicability in the absence of a diabetologist, and flexibility, to rapidly meet changing metabolic requirements. The patients were divided into two groups that were comparable for age, sex distribution, type of diabetes, and type of surgical procedures. The results show that intravenous insulin administration achieved better glycemic control during the intraoperative period, whereas it did not offer advantages over the subcutaneous route during the pre- and postoperative periods. The satisfactory degree of steady glycemic control achieved and the absence of hypoglycemic episodes indicate that the separate administration of insulin and glucose plus electrolytes is an effective and safe management modality for diabetic patients undergoing major surgery.

[Surgery of the saphenous-popliteal junction in the treatment of initial insufficiency of the small saphenous vein].

Insufficiency of the sapheno-popliteal junction may be the first sign of varicose disease, and represents one of several ways that lower limb-venous insufficiency uses to present itself. Doppler ultrasound is particularly helpful in diagnosing this often subclinical insufficiency. Based on satisfactory results in a series of 18 patients treated between 1985 and 1988 (mean follow-up 1.5 years), the authors suggest treating sapheno-popliteal junction insufficiency by means of crossectomy, under local anesthesia, and on an out-patient basis. When surgical treatment is performed during the first stages of the disease, the consequent irreversible damages to the lesser saphenous vein due to stasis are avoided, and thereby, a true varicose state is avoided.

Nasobiliary drainage following endoscopic sphincterotomy. A useful method of preventing and treating early complications.

The authors analyze a retrospective study of 850 patients who underwent endoscopic sphincterotomy (ES). One group of patients (705) routinely had nasobiliary drainage following ES as a prophylactic measure to prevent complications, while 145 patients were not drained. Complications, mortality and the need for emergency surgery were compared in both groups. In the drained group, the complication rate was 2% vs 10.3% in the nondrained group (P less than 0.001), and mortality was 0.4% vs 2.7% (P = 0.03). Emergency surgery was required in 0.1% in the drained patients versus 3.4% in the nondrained group (P = 0.01). Based on these data within the limits of a retrospective study, the authors strongly support the routine use of nasobiliary drainage to prevent complications, which usually occur within the first 24 h, and also to facilitate the immediate treatment of the complications. This procedure is also highly recommended when ES is performed by inexperienced endoscopists and with a technically demanding ES, which is frequently followed by complications.
