Direct trocar insertion for laparoscopy.

BACKGROUND: The Veress needle (VN) technique for establishing pneumoperitoneum in laparoscopic surgery is widely used and yet is associated with slow insufflation rates and potentially life-threatening complications. Although these complications have been rarely reported, they represent a major source of morbidity and mortality from laparoscopic procedures and a major reason for conversion to open surgery. The open laparoscopy (OL) is an alternative to the VN technique, being relatively safer, even if considered cumbersome by many authors. Recently, the direct trocar insertion (DTI) technique of establishing pneumoperitoneum has been reported as an alternative to both techniques, but it is largely confined to gynecologic procedures. We report a case-series study where we evaluate the patients who underwent a DTI entry for laparoscopy during a recent 5-year period, focusing attention on feasibility, safety, and the benefits of DTI. METHODS: This is a case series of 2175 different laparoscopic procedures (1456 [66.9%] scheduled cases and 719 [33%] emergencies). In 2091 (96.1%) of them (1425 [68.1%] scheduled cases and 666 [31.8%] emergencies), pneumoperitoneum was established with DTI, either in the umbilicus or in Palmer's point. RESULTS: There were no injuries, either minor or major. Peritoneal access and the creation of a laparoscopic workplace were obtained quickly and efficiently by DTI. CONCLUSION: Our results suggest that DTI is a fast, safe, and reliable alternative to traditional techniques for pneumoperitoneum establishment and should be regarded as a part of the surgical armamentarium of a trained laparoscopic surgeon.

Incarcerated internal hernia of the small intestine through a re-approximated peritoneum after a trans-abdominal pre-peritoneal procedure--apropos of two cases: review of the literature.

A description of two cases of internal herniation caused by a defect in the closure of the peritoneal flap during a trans-abdominal pre-peritoneal procedure is presented here. They were both successfully treated laparoscopically. This rare condition should be considered when patients who have had recent trans-abdominal surgery for inguinal hernia repair present with colicky lower abdominal pain--its aetiology may well be due to technical error. It is already established that laparoscopy is useful as a diagnostic and therapeutic tool in emergency cases, but it is also true that it is useful in case of early post-operative period complications following any laparoscopic procedure, such as the laparoscopic inguinal hernia repair.

Inguinal-scrotal hernias in young patients: is laparoscopic repair a possible answer? Preliminary results of a single-institution experience with a transabdominal preperitoneal approach.

OBJECTIVES: The laparoscopic trans-abdominal preperitoneal (TAPP) approach to inguinal hernia repair is well documented as an excellent choice in numerous studies, especially when conducted by an experienced surgeon. Its full list of specific indications is still under debate. Generally, the repair of scrotal hernias demands a higher level of experience on the part of the surgeon, irrespective of the applied surgical technique. In this report, we evaluate our preliminary experience of TAPP laparoscopic repair for inguinoscrotal hernias in young patients in a Community Hospital setting, focusing on the feasibility of the technique and the incidence of complications. MATERIALS AND METHODS: Between January 2008 and January 2009 a total of ten consecutive young patients at the "Civil Hospital" in Vittorio Veneto (TV), underwent TAPP laparoscopic repair of bilateral inguinoscrotal hernias. RESULTS: The overall mean operative time was 65 (+/-15) min. All procedures were performed on a day surgery basis. There were no conversions to open repair, no mortality/morbidity or relapsing hernias. The mean follow-up was 14 (+/-2) months. No patients reported severe pain at 10 days, There were no reports of night pain at 30 days. All patients had a return to physical-work capacity within 14 days. All patients were completely satisfied at the 3-month follow up. CONCLUSIONS: Analysis of the short-term post-operative outcomes of our experience enabled us to conclude that, in the proper setting, TAPP can be performed for inguinoscrotal hernia repair with an efficiency comparable to that of normal inguinal hernia repair.

Transabdominal laparoscopic inguinal hernia repair: is there a place for biological mesh?

AIM: An ideal mesh should produce minimal foreign-body reaction and be compatible with human tissue. Studies focusing on these aspects indicate that a biological mesh acts as a scaffold for hernia repair. In this paper, we retrospectively evaluate a consecutive series of patients who underwent laparoscopic transabdominal pre-peritoneal (TAPP) hernioplasty using a biological mesh-Surgisis-fixed with fibrin glue, focusing on the feasibility of the technique and the incidence of complications, especially those related to the type of mesh implanted. METHODS: Between July and September 2006, 11 patients were operated on using TAPP hernioplasty (bilateral or unilateral) and applying a Surgisis mesh affixed by a fibrin sealant. RESULTS: The mean overall operative time was 75 (+/-15) min. All of the surgeries were performed as a day surgery procedure. Any major or minor complications (early or late), such as prosthesis rejection and/or infection, were recorded. There was only one case of recurrence, likely due to technical error. The mean follow-up was 14.5 (+/-1) months. CONCLUSION: On the basis of this initial experience, TAPP hernioplasty with a Surgisis mesh affixed with fibrin glue is feasible, easy to perform, and effective in experienced hands, with good results. The well known characteristics of a minimally invasive and gentle approach, together with the type of mesh implanted and fixation using glue, might explain the encouraging results of this experience. Therefore, this type of mesh might be tailored to not only the sportsman or the patient with a contaminated surgical field, but may also be used in young patients, where there is a fear of leaving behind a long-term foreign body.

The laparoscopic approach in abdominal emergencies: has the attitude changed? : A single-center review of a 15-year experience.

BACKGROUND: Laparoscopy has been practiced more and more in the management of abdominal emergencies. The aim of the present work was to illustrate retrospectively the results of a case-control 5-year experience of laparoscopic versus open surgery for abdominal emergencies carried out at our institution, especially with regard to whether our attitude toward use of this procedure has changed as compared with the beginning of our laparoscopic emergency experience (1991-2002). MATERIALS AND METHODS: From January 2002 to January 2007 a total of 670 patients underwent emergent and/or urgent laparoscopy (small bowel obstruction, 17; gastroduodenal ulcer disease, 16; biliary disease, 118; pelvic disease and non-specific abdominal pain (NSAP), 512; colonic perforations, 7) at the hands of a surgical team trained in laparoscopy RESULTS: The conversion rate was 0.15%. Major complications ranged as high as 1.9% with no postoperative mortality. A definitive diagnosis was accomplished in 98.3% of the cases, and all such patients were treated successfully by laparoscopy. CONCLUSIONS: We believe that laparoscopy is not an alternative to physical examination/good clinical judgment or to conventional noninvasive diagnostic methods in treating the patient with symptoms of an acute abdomen. However it must be considered an effective option in treating patients in whom these methods fail and as a challenging alternative to open surgery in the management algorithm for abdominal emergencies.

Minilaparoscopic colorectal resection: a preliminary experience and an outcomes comparison with classical laparoscopic colon procedures.

BACKGROUND: Laparoscopy has rapidly emerged as the preferred surgical approach for a number of different diseases because it allows for a correct diagnosis and proper treatment. However, it is not being applied in a widespread manner for the management of benign or malignant colorectal disease. Its natural evolution seems to be the development of mini-instruments and optics (diameter,

Incarcerated internal hernia of the small intestine through a breach of the broad ligament: two cases and a literature review.

Two cases of internal herniation through a defect in the broad ligament of the uterus are described. Both were successfully treated laparoscopically. This rare condition should be borne in mind when a middle-aged woman presents with colicky lower abdominal pain. The cause is unknown, but both congenital and acquired origins have been proposed. As far as emergency situations are concerned, laparoscopy has proven to be both a diagnostic and a therapeutic tool.

The misdiagnosis of ruptured abdominal aortic aneurysm: an ancient problem always present. Report of an atypical case.

The rupture of an abdominal aortic aneurysm is one of the most dramatic event in the daily clinical practice. It is often easily suspected when the classical signs of hemorrhagic shock are associated with an anterior (mesogastric) abdominal pain and an expanding mass, especially in the non-obese patients. Sometimes many of these signs can lack and, as a consequence, the diagnosis might be very difficult. This may cause a fatal delay for the patients. We describe a singular case in which the rupture of an abdominal aortic aneurysm was simulating an acute cholecystitis: the presented symptoms, together with a negative personal medical history, were so atypical that even four experienced practitioners misdiagnosed the vascular lesion and the diagnosis was possible only at autopsy.

Primary pulmonary nodular amyloidosis.

Primary nodular amyloidosis of the lung is an uncommon manifestation. The disease runs a benign course, but offers diagnostic problems due to non-specific radiological features entering the big field of the solitary nodule. We describe the case of a 60 year old man with multiple nodules on the left lung operated on diagnostic and therapeutic video-assisted thoracoscopy and discuss the possibilities, if any, of suspecting such a disease through radiologic characteristics along with findings from the patient's history, physical examination and laboratory tests.

Direct trocar insertion vs Veress needle in nonobese patients undergoing laparoscopic procedures: a randomized prospective single-center study.

BACKGROUND: Nonobese patients undergoing laparoscopic procedures present a dilemma as to the correct mode of entry into the abdominal cavity because the Veress needle (VN) technique seems to be associated with a high risk of vascular and visceral injuries. Direct trocar insertion (DTI) has been reported as an alternative to the VN for creation of the pneumoperitoneum. METHODS: An open comparative randomized prospective study was conducted on the feasibility and safety of DTI vs the VN technique in nonobese patients of any age category referred for urgent or scheduled laparoscopic procedures. Exclusion criteria were obesity (defined as a body mass index [BMI] > 27 kg/m(2)), major abdominal distension, and two or more previous abdominal operations. The study endpoints were the feasibility and safety of the DTI and VN techniques. Results were evaluated on an intention-to-treat basis. Statistical analysis was carried out with the t-test for independent samples, the chi-square tests, and the Fisher's exact tests, as appropriate. The level of significance was 0.01. RESULTS: Since January 2002, a total of 598 nonobese patients have been entered into the current trial; 46% (mean BMI 21.6 A+/- 4.4 kg/m(2)) were randomly allocated to DTI, whereas 54% (BMI 21.1 A+/- 5.3 kg/m(2)) were allocated to the VN techniques. Demographic features and type of procedures were similar for the two groups. DTI was feasible in 100% of patients vs 98.7% in the VN group (p = NS). Minor complications were nil in the DTI group and 5.9% in the VN group (p < 0.01). The latter group consisted of 11 cases (3.4%) of subcutaneous emphysema and eight cases (2.5%) of extraperitoneal insufflation. Major complications were nil in the DTI group and 1.3% among VN patients (p = NS). These latter cases consisted of two (0.3%) hepatic lesions managed laparoscopically; one (0.3%) misdiagnosed ileal perforation requiring reintervention, and one (0.3%) mesenteric laceration treated conservatively. CONCLUSION: In thin and very thin patients of any age category with no more than one previous abdominal operation, DTI is a safe alternative to the VN technique and is associated with fewer minor complications. In terms of major complications, there is no difference between the two techniques. Either technique of access is acceptable Thin and very thin patients undergoing laparoscopy, on condition that the basic principles of laparoscopic surgery are complied with.

Gallstone ileus as a complication of acute cholecystitis. Laparoscopic diagnosis and treatment.

Gallstone ileus accounts for 1-4% of all cases of intestinal obstruction, with its incidence rising with age of patients. There is often a long delay between onset of symptoms (usually abdominal pain, vomiting, and bowel distension) and proper treatment, with a simple enterolithotomy as the one of choice. We report a case of an atypical gallstone ileus presented as a complication of acute cholecystitis, treated with a laparoscopic guided enterolithotomy. A 67-year-old woman on the 5th p.o. day after a laparoscopic procedure for an empyematous cholecystitis (no sign of fistula or duodenal perforation and a "negative" intraoperative cholangiography) presented continuous vomiting as the only symptoms of a subileus (radiographic diagnostic images negative for intestinal obstruction or intraluminal gallstone or duodenal fistula). A laparoscopic diagnostic approach revealed a gallstone in the distal jejunum. Through a 5 cm midline incision the intestine, including the gallstone, was brought out extracorporally and the stone was removed by a simple enterolithotomy. The postoperative course was uneventful and the patient had no complaint at a 1-year follow-up. We consider the laparoscopic approach, in patients with "abdominal emergencies," feasible and safe in experienced hands. It provides diagnostic accuracy as well as therapeutic capabilities, as in the case of gallstone ileus we have reported.

[The rationale of laparoscopic treatment in acute appendiceal disease]. / Il razionale dell'approccio laparoscopico alla patologia appendicolare acuta.

Notwithstanding its widely perceived advantages, laparoscopic appendectomy has not yet met with universal acceptance. The aim of the present work was to illustrate retrospectively the results of a case-control study of laparoscopic vs open appendectomy carried out at our institution. From Jan. 1993 to Dec. 1999 a total of 457 patients (M:F = 210:247; mean age 25.2 +/- 15 years) underwent emergency and/or urgent appendectomy. Among them, 254 (55.5%) were operated on laparoscopically, while 203 (44.5%) were treated by conventional surgery The choice of technique depended upon the availability or otherwise of a team expert in minimally invasive surgery. The laparoscopic technique conversion rate was 3.9% and was mainly due to the presence of dense intraabdominal adhesions. The major intraoperative complication rates were 0.39% and 0% in the laparoscopic and laparotomy groups, respectively (P = ns). Major postoperative complications occurred in 2 and 1%, respectively (P = ns). The postoperative mortality rates were 0.4% and 0.5% in the laparoscopy and laparotomy groups, respectively (P = ns). The reoperation rate was 1.1% in the laparoscopic group as against 0% in the open surgery group (P = ns). Minor postoperative complications were observed in 0.8% and 7.5% of patients in the laparoscopy and open surgery groups, respectively (P = 0.001) and consisted mainly of wound infections. Resumption of bowel function was significantly more rapid and the hospital stay significantly shorter in the laparoscopically treated patients. The greater diagnostic accuracy of laparoscopy allowed concurrent diseases to be diagnosed in 9% of laparoscopically treated patients with histologically proven appendicitis as against 1.5% of those treated by conventional surgery (P = 0.001). Similarly, among those patients with no evidence of gross and/or microscopic appendicitis, concurrent diseases were detected in 58.4% of the laparoscopic cases as against only 6% of the laparotomy cases (P = 0.0001). Despite the limitations of a retrospective investigation, on the basis of our experience we believe that laparoscopic appendectomy is as safe and effective as conventional surgery, presents a higher degree of diagnostic accuracy and makes for less trauma and a more rapid postoperative recovery. Such features make its use mandatory in female patients of child-bearing age referred for urgent abdominal and/or pelvic surgery.

Emergency laparoscopy: a community hospital experience.

BACKGROUND: By now, laparoscopic surgery has achieved widespread acceptance among surgeons and, generally speaking, by the public. Therefore, we set out to evaluate whether this technique is a feasible method of treating patients with abdominal emergencies, traumatic or not. To assess the routine use of emergency laparoscopy in a community hospital setting, we undertook a retrospective analysis of an unrandomized experience (presence or absence of a surgeon with laparoscopic experience). METHODS: Between January 1993 and October 1998, 575 emergency abdominal surgical procedures were done in our department. In all, 365 (63.4%) were diagnostic and operative laparoscopy procedures (acute small bowel obstruction: 23 cases; hernia disease: one case; gastroduodenal ulcer disease: 15 cases; biliary system disease: 89 cases; pelvic disease: 237 cases). These cases represent almost 56% of all laparoscopic procedures done during the same period at our institution. Laparoscopy was not performed in patients with a history of a previous abdominal approach to malignant disease, a history of more than two major abdominal surgeries, or massive bowel distension; nor was it used in patients whose general conditions contraindicate this approach. RESULTS: The conversion rate was 6.8%. The morbidity and mortality rates were, respectively, 4.1% and 0.8%. A definitive diagnosis was provided in 95.3% of cases, with the possibility to treat 88.2% of them by laparoscopy. CONCLUSIONS: We consider the laparoscopic approach in patients with abdominal emergencies to be feasible and safe in experienced hands. It provides diagnostic accuracy as well as therapeutic capabilities. Sparing patients laparotomy reduces postoperative pain, improves recovery of GI function, reduces hospitalization, cuts health care costs, and improves cosmetic results. This approach promises to play a significant role in emergency abdominal situations and will certainly become increasingly important in today's health care environment.

Small bowel obstruction. Laparoscopic approach.

BACKGROUND: This is a retrospective review of our experience using a laparoscopic approach in the treatment of acute and chronic small bowel obstruction (SBO). MATERIALS AND METHODS: Of 136 patients hospitalized in our institutions for acute (94 cases: 69.1%) and chronic (42 cases: 30.8%) SBO, from January 1994 to March 1998, 63 (46.3%) were approached laparoscopically. The etiology was accurately diagnosed in 58 cases (92%), and it was possible to treat it laparoscopically in 82.5% (52 of 63 cases). In the remaining 11 cases (17.4%), a formal laparotomy was needed for bowel resection, due to an ischemic small bowel or for malignant disease. RESULTS: Overall, 82.5% of our cases were successfully treated laparoscopically. CONCLUSIONS: We conclude that, in experienced hands, laparoscopy is an excellent diagnostic and, in the majority of cases, a therapeutic surgical approach in selected patients with acute or chronic SBO.

Laparoscopic management of colonoscopic perforations.

Colonic perforation is a dangerous complication of colonoscopy, both diagnostic and therapeutic, and its management has become controversial. The question of conservative vs operative treatment is still under debate. Despite the recent expansion and wide acceptance of laparoscopy by surgeons, the feasibility of this technique as a means of treating abdominal emergencies has also been questioned. Of 575 patients admitted to our institution for abdominal emergencies between 1993 and 1998, 365 were treated via a laparoscopic approach. Two of these patients were treated for colonoscopic perforations, one after a diagnostic procedure and one after an operative procedure. Our technique employs an open umbilical approach with two other trocars introduced in the right iliac fossa and left flank. In the first case, a diverticular perforation of the subperitoneal rectum was suspected. The abdomen was copiously irrigated with saline solution and a drain was left in the pelvis. In the second patient, localized peritonitis was found in the left iliac fossa due to a microperforation of the sigmoid colon. It was repaired with a single absorbable suture. The postoperative course was unremarkable in both cases. In patients with an emergency abdomen due to a postcolonoscopy perforation, we consider the laparoscopic approach feasible and safe in experienced hands. It allowed us to avoid an unnecessary laparotomy and other time-consuming and expensive diagnostic investigations. This approach represents an excellent means of managing this type of emergency abdominal situation.

Gallbladder melanoma mimicking acute acalculous cholecystitis.

Gallbladder (GB) melanoma is a rare entity with a dismal prognosis. Its primary or secondary status is difficult to establish in the absence of an overt cutaneous localization. We report herein the case of a misdiagnosed GB melanoma mimicking acute acalculous cholecystitis that was treated by means of laparoscopic cholecystectomy (LC). A 54-year-old man was referred to our institution for acute cholecystitis. Apart from the ablation of some nevocytic nevi 7 years before admission, the patient's medical history was unremarkable. The ultrasound (US) examination showed a slightly enlarged acalculous gallbladder with thickened walls and a well-circumscribed polypoid mass in the fundus. The patient was treated medically and referred to LC. At surgery, some satellite nodules were visualized in the GB hepatic bed. The GB was removed, and two hepatic nodules were excised. Histology showed a pT3 melanoma. The patient underwent an open hepatic wedge resection 3 weeks after laparoscopy. No recurrence was observed at 6-month follow-up. To date, only one case of melanoma of the gallbladder treated with LC has been reported. GB melanoma is a diagnostic challenge when there is no evidence of a primary lesion. However, the occurrence of acalculous cholecystitis and a GB polyp in patients with a positive history of mole ablation should alert surgeons to the possibility of a melanoma.

[Laparoscopic approach to inguinal hernia pathology]. / Approccio laparoscopico alla patologia erniaria inguinale.

Laparoscopic hernia repair has already become as accepted a technique as the conventional ones and is routinely used in those centres where this kind of surgery is normally performed. The two most commonly used laparoscopic techniques (transabdominal and total extraperitoneal) have been shown to produce good results in terms of post-operative course and recurrence rates, but still present the disadvantages of high cost and the need for general anaesthesia. We report here a retrospective analysis of our early experience with laparoscopic treatment of inguino-crural hernias. The positive results achieved (no cases of conversion to an open technique; no recurrences to date; 4.7% major morbidity) allow us to consider this approach a valid alternative to the traditional ones in selected, well-informed patients.

[Emergency laparoscopic surgery: a hospital's experience]. / Chirurgia laparoscopica d'urgenza: un'esperienza ospedaliera.

BACKGROUND AND AIM: The wide diffusion and increasing use of laparoscopic surgery prompts the authors to broaden discussion to its validity and diagnostic-therapeutic use in emergency abdominal surgery. The aim was to evaluate the efficacy of laparoscopic surgery in the light of reports in the international literature and in relation to the situation in our hospital. METHODS: From April 1994 to May 1998, out of 1016 emergency abdominal operations performed at our hospital, 783 (77.5%) used a laparoscopic approach for diagnostic and therapeutic purposes: intestinal occlusion: 26 cases; gastrointestinal ulcer pathology: 15 cases; hepatobiliary pathology: 398 cases; "pelvic" pathology: 305 cases; colic pathology: 39 cases. These represent 24.4% of all laparoscopic procedures carried out during the same period. We preferred to use immediate laparotomic access in patients with the following characteristics: anamnesis of previous surgery for malignant pathologies; anamnesis of more than two major abdominal operations; massive intestinal distension; patients whose general conditions were a contraindication to a laparoscopic approach. RESULTS: The conversion rate was 6.2% (49 cases) with morbidity of 3.4% (25 cases) and a mortality rate of 0.2% (2 cases). A final diagnosis was made in 763 patients (97.4%) with the possibility of treating 719 of them (94.2%), again using a laparoscopic approach. CONCLUSIONS: It is right to regard the laparoscopic approach in emergency abdominal surgery as a feasible and safe model, offering a high potential for diagnosis and therapy if appropriately performed by an expert and well coordinated team. The increased experience of mini-invasive surgery and the improved range of instruments available make the laparoscopic approach a valid alternative to laparotomy, even in the event of emergency abdominal pathologies.
