RESUMEN

BACKGROUND: One advantage of laparoscopic surgery over open surgery is the absence of laparotomic incisions. This advantage is reduced when an auxiliary incision is performed to remove surgical specimens larger than the trocar. METHODS: A special incision was performed at umbilical trocar level that enabled removal of a large surgical specimen as in right hemicolectomy (colic), gastric resection, and splenic surgery. RESULTS: The authors have used this method routinely for 10 years for all cases requiring removal of a surgical specimen too large for the normal incision of a 10-mm trocar. CONCLUSION: The authors maintain that this method avoids the use of auxiliary incisions, which undo the many benefits of laparoscopic surgery.

RESUMEN

BACKGROUND: Incisional hernia is a frequent complication of abdominal surgery (2-20% of all cases). Recurrence rate after simple repair without mesh is very high. The use of prosthetic materials has reduced the recurrences. Over the past decade, laparoscopic repair of incisional and umbilical hernias has become an interesting alternative to open procedure. PATIENTS AND METHODS: The aim of this retrospective study was to evaluate efficacy, safety and advantages of laparoscopic approach in the treatment of incisional and umbilical hernias. From February 2000 through June 2006, a total of 127 incisional hernias (primary and recurrent), 21 umbilical and 19 epigastric hernias, were treated by laparoscopic approach. The exclusions for laparoscopy were: defect size less than 2 cm or more 20 cm, anesthesiologic problems, hemocoagulative disorders. The females/males ratio was 0/7, with a mean age of 59 years (range 24-83). The abdominal associated disease treated were 26. Three cases were treated as urgencies (strangulated hernias). RESULTS: The conversion rate was 2 cases (1.2%). Mean operative time was 78 min (range 25-170). The mean postoperative hospital stay was 2.1 days (range: 1-5). The intra- and postoperative complication rate was 5% (above all seromas). The recurrence rate was 1.8% (3 cases). CONCLUSIONS: More studies with long-term follow-up are necessary to prove the advantages of laparoscopic technique, but this large experience of more than 5 years, demonstrates that in selected cases the laparoscopic approach may be an interesting and effective alternative to open technique.

RESUMEN

AIM: Morbid obesity has increased its frequency in the last 20 years in association with the increase of a country's richness. Bariatric surgery has developed a role which is becoming more and more important. The aim of this study, after 10 years of experience with the biliopancreatic diversion, is to compare the laparoscopic versus open technique METHODS: From March 1993 to December 2004, 150 patients were operated by biliopancreatic diversion. We divided our experience into 2 groups: laparotomic and laparoscopic techniques. We compared the following variables in the 2 groups: total operating time, intestinal functions, postoperative pain, patient's discharge and recovery time, major postoperative complications, postoperative mortality, late complications, incisional hernia incidence and anastomotic ulceration. RESULTS: We found a significant difference in both the reduction of the postoperative pain and the recanalization time in the laparoscopic group. Equally, we found a reduction in the incidence of abdominal wall complications, especially the reduction of incisional hernia and infections. The mean operative time was longer in the laparoscopic group, in particular due to the hard learning curve. CONCLUSIONS: The laparoscopic biliopancreatic diversion is a feasible and safe operation with good results: less postoperative discomfort, shorter recanalization and ospedalization time, less incidence of abdominal wall morbidity (incisional hernia). However, the procedure may prove difficult and it needs a highly experienced surgeon in laparoscopic technique.

RESUMEN

AIM: About 2/3 of the Western population over the age of 80 years are affected by colic diverticulosis; 25% will develop diverticular disease with or without complications: fistula, obstruction, pericolic abscess, free perforation or hemorrhage. Laparoscopic approach for benign diseases of the colon such as diverticulosis, Chrohn's disease, etc. is unanimously considered as a very effective procedure. We have performed a retrospective analysis of 9 years with laparoscopic approach of the diverticular disease. The purpose of this study was to determine the feasibility, safety and benefits of laparoscopic approach. METHODS: From May 1994 to November 2002, 69 patients affected by non-complicated diverticular disease, were treated laparoscopically, at the Mininvasive Surgery Department of Spoleto. In the same period other 213 patients suffering from cancer of the colon-rectum were operated through laparoscopic surgery. A colosigmoid resection with mesenteric inferior artery preservation was performed in 46 cases (67%). RESULTS: We have performed only a laparoscopic colectomy technique (no hand-assisted procedures); the convertion rate was of 7.2%, the mean operative time was 145 min, no intraoperative complications were observed and finally the mean hospital stay was of 7.4 days (6-9). The postoperative complications were 1 case of infection of the umbilical scar and 1 case of pleural effusion with bronchopneumonia. CONCLUSIONS: Elective laparoscopic colectomy for diverticular disease is feasible, safe and gives very good results: minimum postoperative discomfort, rapid recovery, low mobility and postoperative stay, rapid return to normal activities. However, in some cases, this procedure can be extremely difficult because of previous inflammatory complications (adhesions, fistulas or stenosis), therefore, high surgical skills in laparoscopic-colic surgery are required.

RESUMEN

BACKGROUND: Breast tumour takes first place for frequency in women in Western Countries and is in constant increase. The diagnosis of the so-called non palpable lesions is increased remarkably above all due to the diffusion of mammographic screening and to a greater awareness of the problem. Furthermore it is helped by an important development of mininvasive diagnostic methods: the traditonal cytology with fine needle is supported by various trans-skin bioptic procedures (micro-histological examination). This methods almost always replaces the surgical excisional biopsy and frozen intraoperative examination, still used but reserved for particular cases. PATIENTS AND METHODS: In our Department of General and Mininvasive Surgery, from December 1999 to September 2004, we carried out 214 biopsies, with the collaboration of the radiological Service, under echographic guidance using vacuum--assisted biopsy (Mammotome) with 11-Gauge needle. The results are examined and discussed here in this report with regard to diagnostic accuracy, quantity and quality of information, significant for subsequent surgical management. RESULTS: Of 214 biopsies carried out with Mammotome technique, 89.3% of the cases are clinically non palpable lesions, with a average diameter of 8 mm. The average age of patients was 57.6 years (range 31-88). There are 90 cases of positive malignant pathology (42%). In the atypical ductal iperplasia and radial scar cases (6%) surgical removal of lesion was carried out which confirmed the previous bioptic diagnosis in 100% of cases. The 19% of patients submitted to a Mammotome biopsy was subject previously to cytology with fine needle. Comparing the results of both methods the diagnostic reliability of Mammotome was significantly superior (p < 0.05) as also the amount of information obtained (histotype, invasivity, grading, estrogen receptor, etc.); discomfort linked to the procedure, valued as pain (VAS), resulted inferior to the discomfort of biopsy with fine needle. The only complication of Mammotome biopsy is represented by haematoma in the biopsy site (8% of cases). The number of false negatives was one case due to incorrect targeting. CONCLUSION: In the present situation, the choice of method is conditioned by the degree of radiological suspicion, taking into account the information obtained thereby, in order to ensure the appropriate surgise management. Mammotome biopsy of non palpable lesions of the breast, in our experience, is preferable if suspicion of malignancy is high. In this way a correct preoperative strategy can be prepared. Including the sentinel lymphnode method. Consequently a decision regarding the type of surgery can be taken (generally conservative), as well as making easier the intraoperative localisation of lesion by positioning the metallic clips during biopsy.

RESUMEN

AIM: The laparoscopic approach to malignant diseases runs up against both old and new problems: respect for the principles of radicality, operating times, the postoperative course and surgical complications, long-term oncological results in terms of survival and recurrence of the disease. One of the problems which has received most attention regards the onset of a metastasis on a trocar scar or a mini-laparotomy recurrence. Trocar site tumor recurrences have been described in the literature following laparoscopic surgery in almost all abdominal malignant pathologies (colorectal, gynaecological, pancreatic, etc.) and even after thoracoscopy. The real frequency is currently of the order of 1% (0-2%) in colic surgery and of 14% (10-17%) after cholecystectomy for occult gallbladder carcinoma. METHODS: A retrospective survey was carried out of our laparoscopic experience; between 1994 and 2002 213 colic resections were carried out for cancer; we also observed 18 occult carcinomas of the gallbladder in 2386 laparoscopic cholecystectomies for lithiasis. RESULTS: Respectively 2 cases (11%) of trocar site neoplastic recurrences in gallbladder carcinoma and 2 cases (0.9%) from colon carcinoma were observed. CONCLUSIONS: The real extent of the problem would appear to be on a much lesser scale at the moment than was initially thought, especially as regards colic surgery. The multifactorial aetiology of the problem explains the importance of their prevention, on the basis above all of rigorous respect for the rules and protocols of laparoscopic technique.

RESUMEN

BACKGROUND: Laparoscopic colo-rectal surgery has gained wide acceptance as a treatment in a variety of benign and malignant diseases. The reproducibility and safety of all the principal colo-rectal procedures has been demonstrated, but some indications are still controversial. A great part of surgeons perform right hemicolectomy by laparo-assisted technique and consider it more difficult than left hemicolectomy. METHODS: A retrospective analysis of a series of 180 laparoscopic colon resections performed between 1994 and 2001 is presented. Surgical indications were: 46 cases of benign disorders and 134 colonic malignancy. The right hemicolectomy were 27 (15%): 2 benign and 25 malignant diseases. The technical aspects of completely laparoscopic right hemicolectomy is described in details. A completely mechanical intra-corporeal anastomosis is always performed. To remove the bowel specimen from the abdominal cavity it is put it in a large bag and pull it out of a 3-4 cm enlargement of a trocar-site (in the umbilical scar). RESULTS: Data of the 27 laparoscopic right hemicolectomy were analysed: there was 1 conversion to open surgery; no intra-operative complications were observed; the postoperative period was complicated by 1 anastomotic fistula. The median operative time was of 150 minutes. No case of port-site recurrence was observed. CONCLUSIONS: The laparoscopic colo-rectal surgery can reproduce in selected patients, the techniques performed in open surgery with minimally invasive treatment. It is possible to perform a completely laparoscopic right hemicolectomy after an adequate training in advanced laparoscopy, anyway there are many advantages: less postoperative pain, short-term postoperative ileus, earlier return to daily activity.

RESUMEN

Acute appendicitis is one of the most common surgical disease but, in spite of the progression diagnostic imaging, a definite diagnosis is frequently difficult and often is based in essentially clinical grounds. The Authors retrospectively analyze the results of conventional laparotomic appendectomy (CLA) and videolaparascopic appendectomy (VLA) as performed by two teams of their Department of Surgery. Between January 2000 and November 2001, 156 patients, age ranging from 3 to 67 yrs, underwent surgery because suspected acute appendicitis; 96 patients underwent VLA and 60 patients underwent CLA; a diagnosis of acute appendicitis was confirmed in 142 cases (91%). The patients who had a confirmed diagnosis of acute appendicitis were grouped according to clinical-pathologic criteria into follicular, gangrenous and complicated appendicitisi; operating time, complications and length of hospital stay were compared among the three groups. VLA resulted superior to CLA in terms of diagnostic performance: among the patients with suspected acute appendicitis, VLA allowed to establish a different diagnosis in 41% as compared to 13% with CLA. In two cases (2.08%) VLA was turned into CLA. There were non differences between VLA and CLA in terms of surgical operating time and hospital stay. A significantly higher incidence of surgical complications, such as wound infections and pelvic abscesses, was observed in the CLA group as compared to VLA. The Authors conclude that VLA allows a complete exploration of the abdomen, a better localization of the appendix and an easier diagnosis of unexpected conditions or pathologic processes associated with the clinical appendicitis; further, VLA is gravated by fewer complications.

RESUMEN

It is now unquestionable that varicocele represents one of the main causes of male infertility, and thus requires appropriate surgical treatment. Inguinal and retroperitoneal methods have for some time been the most widely used. However, a significant postoperative morbidity and relatively long convalescence have prompted the search for alternative surgical techniques, such as percutaneous sclero-embolisation and microsurgery. Laparoscopic treatment of varicocele is a relatively recent surgical technique. The first studies by Sanchez de Badajoz date back to 1988 and to date a relatively small number of cases have been reported. The authors analyse the results in 54 patients treated over a period of two and a half years; 13 cases also presented inguinal hernia pathology which was treated during the same operation by applying a polypropylene graft again using a laparoscopic approach; the latter method has been routinely applied since 1992 in over 1000 cases with excellent results. The internal spermatic artery was always identified and preserved. No peri- or postoperative complications were observed. A follow-up was performed at 10 months after surgery and showed results which although referred to a relatively small series, were certainly better than those reported in the literature using traditional surgical techniques; in addition, this method also reveals interesting possibilities for the treatment of associated pathologies during the same operation, with obvious advantages in terms of costs and patient compliance.
