Retroperitoneal paraduodenal unicentric Castleman disease: case report and review of the literature

Castleman disease is a rare and benign disorder, characterized by enlarged lymph nodes and angiofollicular lymphoid hyperplasia. We report a case of a 57-year-old male, who was admitted to our surgical department because of a retroperitoneal nodular mass measuring about 4 cm in maximum diameter, incidentally discovered on a radiologic exam performed for the onset of vague abdominal pain with posterior irradiation. The patient was subdue to laparoscopic removal of the mass and no intra- and post-operative complications were recorded. Histologic diagnosis of hyaline-vascular variant of the Castleman disease was confirmed. Only two cases have been found in the literature reporting the paraduodenal unicentric Castleman disease localization like our case. Although rare, the Castleman disease must be considered in the differential diagnosis among all the lymph nodes diseases, for avoiding improper therapies.

An unusual association between pancreatic cancer and Purtscher-like retinopathy: Presentation of a unique case

INTRODUCTION

Purtscher's retinopathy causes sudden loss of vision of varying severity, secondary to head injury or chest compression. Its pathophysiology is unclear. Purtscher's-like retinopathy has more attenuated clinical and objective features and can be associated with many non-neoplastic pathologies. Otherwise, an association of this kind of retinopathy with malignancies has been described once in the Literature. We present a case report on a unique association between pancreatic cancer and Purtscher-type retinopathy.

CASE PRESENTATION

A 79-year-old man with reduced central vision in both eyes required an ophthalmic evaluation. Visual acuity was 20/40 in the right eye and 20/50 in the left eye. Fundus examination showed yellow-white peripapillary spots and bilateral retinal hemorrhages in the superficial retina. The patient complained of abdominal pain and received a CT scan of the abdomen, which showed a pancreatic mass extending into the spleen. A percutaneous needle biopsy sample showed mucinous pancreatic adenocarcinoma.

CLINICAL DISCUSSION

This case report should warn of a possible association between pancreatic adenocarcinoma and Purtscher's-like retinopathy.

CONCLUSION

Patients with this kind of retinopathy should be evaluated to rule out not only benign associated disease, but also malignant tumors of the pancreas.

Ergonomics in laparoscopic surgery

BACKGROUND AND OBJECTIVES

Laparoscopic surgery is a widely used surgical technique, whose benefits either for patients or for surgeons are well-recognized. Despite the rise in the use of this technique, the ergonomics of the operating room is still very low. The consequence is that injuries and illness related to laparoscopic surgery are present. The aims of this study are to investigate how an increase in the surgeon' perception of the fatigue during the execution of the intervention influences the surgeon' health, and to evaluate if there is a correlation between the increase in fatigue and the operating field dimension.

MATERIALS AND METHODS

The observation was conducted on a single laparoscopist working at our Institution and the Borg CR 0-10 scale was used to perform this study. Two groups of 20 surgical procedures each were analysed. Group A included laparoscopic procedures whose operating field comprehended only one abdominal quadrant. Group B included laparoscopic procedures where at least two abdominal quadrants were involved in the operative field.

RESULTS

The results from both groups were statistically compared. There was a significant correlation between the increase in perception of the exertion and duration of the intervention in both groups and a significant difference in term of Borg scale value, which was higher in group B where the laparoscopic surgery was performed on more than one quadrant of the abdomen.

CONCLUSION

We suggest an important improvement in the ergonomic aspects, especially in more complex laparoscopic procedures that require longer operating time and include more than one abdominal quadrant.

Appendicular schwannoma Review of the literature on a rare benign tumor often mistaken for hyperplasia

INTRODUCTION

Appendicular schwannoma is a rare benign neoplastic proliferation of the appendicular Schwann cells. It is often asymptomatic until it occludes the appendicular lumen thus causing appendicitis-like symptoms.

EVIDENCE ACQUISITION

The neoplastic proliferation of the Schwann cells, although benign, may rarely degenerate into a malignant neoplasm, thus denoting the importance of diagnosis. Some Authors in the Literature used the term "neuroma" or "neurinoma" to indicate either a hyperplastic proliferation of the Schwann cells or its neoplastic but benign proliferation, thus raising the important question of a probable mistaking of these two different histologic entities. The hyperplastic proliferation is usually subsequent to a chronic appendicular inflammation, and it is a more common finding in specimen of appendectomy.

EVIDENCE SYNTHESIS

Aim of the study is to review the published scientific papers about the rare histologic entity of appendicular schwannoma and to define the not clear aspects of Schwann cell neoplasia versus hyperplasia. A review of the Literature from Medline/Pubmed has been accomplished. Forty-four studies from the Literature resulted suitable for our study.

CONCLUSION

Appendicular schwannoma has to be considered in patients with recurrent right lower quadrant pain, and may affect the patient's prognosis if it remains undiagnosed, since it may degenerate in malignancy. There is a lack of clarity in the Literature about the distinction between the hyperplastic and the neoplastic benign Schwann cells proliferation, which must be clarified. The meaning of the terms "neuroma" and "neurinoma" should be standardized, the first referring to the hyperplastic proliferation, and the second to the neoplastic but benign proliferation of the Schwann cells.

KEY WORDS

Appendiciis, Appendectomy, Appendicular neuroma, Appendicular neurinoma, Appendicular schwannoma.

Offending staple as an unusual but preventable cause of internal hernia with bowel obstruction Case report and review of the Literature

In the laparoscopic era, the use of the stapler is a common practice and it adds to the possible causes of post-operative bowel adhesions with obstruction. In this study, we reviewed the Literature in order to study the pathogenesis and the incidence of bowel obstruction after using the laparoscopic stapler. Furthermore, we report a case of a woman who went to our observation for incoming bowel obstruction after laparoscopic ileal resection. In the emergency setting, the laparoscopic exploration revealed that a staple created adherence between an intestinal loop and its mesentery with consequent internal hernia and volvulus. The patient was treated by laparoscopy with removal of the offending staple and resection of the intestinal necrotic segment. Tips and tricks of the surgical technique for avoiding such rare but threatful complication, are discussed. KEY WORDS: Internal hernia, Mechanical bowel obstruction, Laparoscopic stapler, Volvulus.

Management of a kidney stone in ectopic pelvic kidney with Extracorporeal Shockwave Litothripsy: Description of a case and revision of literature

Urolithiasis is one of the most frequent disease in the population and it represents one of the most frequent causes of access to emergency department. In addition. congenital anomalies occur more often in the kidney than in any other organ and the association of both renal abnormalities and stones is of clinical relevance. In this report, we discuss a case of a women with pelvic ectopic kidney affected by a large pyelic stone treated with ESWL (Extracorporeal Shockwave Lithotripsy).

Transmission ways of Echinococcus granulosus in rare muscular locations of hydatid disease

The most common modality of transmission of the Echinococcus granulosus is through the alimentary tract. Other ways of infestation are questionable. Airborne penetration of bronchial venules to reach the heart and the systemic circulation has been advocated, but never demonstrated. Direct subcutaneous contamination through an injured skin has also been considered. Moreover, the hypothesis that a contamination different from eggs ingestion is not possible, is justified by the reason that eggs transform into larvae in the gastro-intestinal environment. Therefore, it is accepted the possibility that parasites might reach organs and tissues other than liver and lungs through a lymphatic or venous shunt that skip the portal filter. In cases of myocardial muscle or skeletal muscle involvement, it could be speculated that eggs of Echinococcus granulosus might hatch not only in the gastrointestinal tract, but also in soft tissues due to the lactic acid produced by the muscle. These unconventional ways of transmission suggest that the lifecycle of the Echinococcus is not at all known and must be revised. Issues that can help in ideating new therapies may emerge.

Hemocoagulative post-operative changes after laparoscopic surgery compared to open surgery: the role of lupus anticoagulant

Although still debated, post-operative modification of hemostasis seems to be less pronounced after laparoscopy compared to open surgery. Antiphospholipid antibodies might play a role in the post-operative thromboembolic risk, although their evaluation in surgical patients has never been performed. Post-operative modification of antiphospholipid antibodies could be related to the surgical approach (laparoscopic or open). In this prospective study, the authors statistically compared the pre-operative values and post-operative modification of antiphospholipid antibodies in two homogeneous groups of patients operated on by laparoscopic and open surgery. No statistical differences within each group and between the two groups were shown comparing mean values of pre-operative and post-operative antiphospholipid antibodies. In the open group, there was a significant difference between pre-operative and post-operative LAC means (P < 0.01). In the laparoscopic group, on the contrary, no significant change in LAC values between pre- and post-operative tests (P = 0.55) was observed. Since LAC could be related to coagulation disorders, this study seems to support that laparoscopic surgery might induce a less risk of post-operative thromboembolic disease.

Idiopathic intramural hematoma of the right colon. A case report and review of the literature

•

A very rare case of spontaneous colon hematoma has been reported.

•

The rarity of our case of colon hematoma is due to the fact that it is idiopathic.

•

The topic is still under discussion in the Literature since the pathophysiology remains still unknown.

Introduction

Intestinal hematoma is usually observed after an abdominal trauma or in patients treated with anticoagulant therapy. Conversely, idiopathic bowel hematoma is very rare, being colon involvement sporadic with few reports in the Literature.

Presentation of case

The Authors report a case of idiopathic spontaneous large bowel hematoma. A 48-year-old man was admitted for a thoraco-abdominal pain and signs of acute abdomen and fever. After ruling out heart diseases, a CT scan revealed a marked thickening of the ascending colon wall, obstructing the bowel lumen. Leukocytosis was observed. In an emergency setting, an explorative laparotomy was performed. Hemoperitoneum and a large hematoma involving the caecum and the ascending colon were detected, together with intramesenteric and retroperitoneal blood effusion. A right hemicolectomy was accomplished. Histopathology confirmed the diagnosis of large bowel hematoma. Post-operative molecular diagnostic testing for coagulative disorders failed to demonstrate any genetic variation associate with hemorrhagic predisposition.

In the post-operative course, the patient experienced a left basal bronco-pneumonia with increased unilateral pleural effusion, successfully treated by a thoracic drain and antibiotic therapy.

Discussion

The reported case and Literature data show that diagnosis of idiopathic colon intramural hematoma is challenging, especially in the emergency setting. Although conservative therapy is the first line treatment, surgery still has an important role when the diagnosis is uncertain, medical treatment fails or a complication, such untreatable bleeding, perforation or occlusion occur.

Conclusion

The Authors report a very rare case of spontaneous intramural hematoma of the right colon. Surgery still has a role in selected cases.

Intragastric enucleation of stromal tumors through a combined laparoscopic and endoscopic approach

Dear Editor, We read with great interest the paper entitled "Laparoscopic organ-preserving gastric resection improves the quality of life in stromal tumor patients: an observational study with 23 patients" written by Ozcan et al. in Ann Ital Chir. 2018 Oct 23;7 1. We agree with the Authors that preserving the stomach after excision of stromal tumors is essential to improve the patients' quality of life. We would like, however, to discuss some issues that the paper published by Ozcan et al. might raise. When feasible, laparoscopic surgery is the best procedure for removal of gastric stromal tumors, since it is associated with all the advantages already recognized to the mini-invasive approach 2,3. Furthermore, it allows reducing the entity of the resected stomach wall and, therefore, it may help maintain the stomach functions and a post-operative excellent quality of life. Besides the standard laparoscopic procedure with wedge resection of the stomach, we would like to draw the attention that other mini-invasive procedures might be performed. The standard surgical treatment of gastric stromal tumors typically involves full-thickness resection of the tumor site stomach wall. Surgical treatment could be technically challenging for proximal gastric lesions located near the gastro-esophageal junction. In the article by Ozcan et al. it is not well defined how they approached iuxta-cardial stromal tumors. A combined endoscopic/laparoscopic intraluminal enucleation technique has been proposed by some Authors, including us, in these cases 4-6. Our technique consisted in inserting two 5-mm radially expandable trocars through the abdominal and gastric walls. Through the 5-millimeter trocar, a laparoscope was introduced into the gastric cavity and with an endoscopic polipectomy snare introduced per mouth, the gastric iuxta-cardial lesion was grasped and tractioned. Through the other 5-mm laparoscopic trocar, the iuxtacardial gastric lesion was then removed with a complete submucosal resection. The excellent exposure of the site of excision allowed by the endoscopic traction was essential in this step. The specimen was then pulled away from the mouth after its introduction into a small plastic bag and the gastric holes were closed with monofilament non-absorbable sutures. In selected cases of submucosal iuxta-cardial gastric stromal tumors, as well as in every small stromal gastric lesions, the laparoscopic-endoscopic technique should be preferred since it allows a complete safe and oncologic resection of submucosal lesions, reducing risk of complications (e.g., perforation) and lowering morbidity when compared to other open or laparoscopic approaches.

A rare case of epithelioid hemangiothelioma of the quadriceps

Hemangioendotelioma is a group of rare vascular tumors with border-line behavior. They may involve internal organs, limbs, bones and soft tissue. The histological variant epitheliod hemangiothelioma is locally aggressive and has metastatic potential. We present a case of a 41-years old woman affected by epitheliod hemangiothelioma of the right quadriceps. The patient complained of localized pain in the anterior region of the right thigh, which started about 3 months earlier during physical exercise. For the increasing size of the lesion, the patient was referred to our Department. On physical examination, the lesion appeared elastic, fixed to the surrounding tissues and painful under pressure. An ultrasound examination revealed a small avascular lesion and a MRI examination showed an oval formation measuring about 18 mm in diameter of nonspecific significance. A surgical removal of the lesion was performed and diagnosis of epithelioid hemangiothelioma was achieved. A complete removal of the quadriceps muscle was then accomplished. In this paper, clinical and oncologic aspects of this rare tumor are discussed KEY WORDS: Epithelioid hemangiothelioma, Lower limbs tumor, Rare tumors.

Surgical management of hereditary spherocytosis Current strategies

BACKGROUND

Hereditary spherocytosis is a benign hematologic disease, which needs surgical treatment when medical therapy fails. Currently, the surgical strategies consist mainly in total or partial splenectomy, which can be performed either in open or in laparoscopic fashion. In this study, we analyzed our series of splenectomies for hereditary spherocytosis and we discuss about the surgical management, reviewing the Literature.

MATERIAL AND METHODS

Twenty-seven patients (mean age 16.5 years, range 8 - 30 years) affected by hereditary spherocytosis were retrospectively evaluated. Indication to surgery was based on hemolysis severity. Thirteen patients were submitted to laparoscopic splenectomy and 14 to open splenectomy, after preventive specific vaccinations. Cholecystectomy for associated cholelithiasis was performed during the same operation in 4 laparoscopic patients and in 6 open patients.

RESULTS

Main reasons for performing splenectomy were anemia unresponsive to iron supplementation in 7 patients (42%), splenomegaly in 6 patients (37%), and jaundice in 4 cases (21%). All the patients had a severe disease with hemoglobin level below 80 g/L, median reticulocytes count 6,5%, median value of indirect bilirubin concentration 2,0 mg/dL. Indications to splenectomy were increased need for red cell transfusions in 11 patients (66%) and symptoms related to cholelithiasis in 6 patients (34%). A post-operative early complication was observed after open splenectomy, consisting in a pancreatic fistula, which was treated conservatively. No post-operative complications were observed after laparoscopic splenectomy. Neither intra-operative complications nor conversions to open surgery were recorded during the laparoscopic approach. In a long-term follow- up, no infective complications were recorded.

CONCLUSIONS

According to our results, total splenectomy is associated with good results and few complications. In our opinion, it remains the best therapeutic option in selected adult patients non-responder to the medical treatment.

Laparoscopic surgery with total mesocolic excision in colon cancer. A systematic review of the literature

PURPOSE

Nowadays, there is no standardization in surgical procedures for treatment of colon cancer. Since its introduction, laparoscopic surgery has gained increasing interest in colorectal surgery and it is now performed worldwide for treatment of colon cancer. Following the concept of total mesocolic excision introduced by Heald in 1988 in order to reduce local recurrence after surgical treatment of mid/low rectal tumors, the idea of complete removal of the mesocolon mesocolic envelope has been developed also for colon cancer, has evolved longtime and complete mesocolic excision has been recently adopted as the optimal approach for colon cancer. However, complete mesocolic excision, whose purpose is to remove all lymphatics and lymph nodes draining the tumor, is still discussed as far as oncologic results are concerned. Moreover, the role of laparoscopic approach for complete removal of mesocolon has to be defined.

METHODS

Selection of studies. A MEDLINE-PubMed database search of the current English Literature was performed using the terms: complete mesocolic excision; high vascular ligation; splenic flexure mobilization.

INCLUSION CRITERIA

The inclusion criteria were report on CME for colonic cancer with high vascular ligation; minimum number of patients included (20 patients). Two independent reviewers (CRS, IE) extracted the data.

RESULTS AND CONCLUSION

In this article, an update from the Literature on results of complete mesocolic excision was undertaken and data have been discussed. The role of laparoscopic complete mesocolic excision in colon cancer patients has been focused, and it seems to be safe and feasible, it should be standardized and hypothetical oncologic advantages should be expected.

Topical hemostasis in laparoscopic surgery

A major goal during any surgical intervention is minimization of blood loss, which reduces the need for blood transfusion. In open surgery, the possibility for the surgeon to use the hands directly in contact with the bleeding tissues for hemostasis, makes mechanical methods, such as compression, ligatures or sutures, important to achieve proper hemostasis. In laparoscopic surgery, where the intervention is performed by means of small incisions through which the surgeon's hand cannot directly achieve the tissues, the problem of hemostasis is critical and needs more attention. Either in open or in laparoscopic surgery, significant bleeding during surgery is controlled through vessel ligation, suturing, and electrocautery. Topical hemostatic agents are useful adjuncts to surgical hemostasis for controlling non-specific bleeding. The introduction of different devices and topical agents has made possible to perform more complex interventions also in laparoscopy. The Authors discuss about the type, the field of application, the side effects of the hemostatic devices and of the topical hemostatic agents.

Totally implantable catheter migration and its percutaneous retrieval: case report and review of the literature

Totally subcutaneous intravascular portals have been increasingly used to administer long-term chemotherapy and parental nutrition. The reported complications are rare. Accidental endovascular rupture of a fragment of catheter is one of the most formidable complications of the central vein catheterization. The Authors report a case of deployment of a Port-a-Cath catheter and its percutaneous retrieval. The catheter accidentally detached and migrated from the reservoir of the port-a-cath placed in the left subclavian vein to the right heart cavities through the blood stream. A review of the Literature is also given, focusing on the possible factors responsible for this unusual complication.

Colorectal cancer in aged patients. Toward the routine treatment through laparoscopic surgical approach

AIM

Colorectal cancer is one of the most common malignancies in general population. The incidence seems to be higher in older age. Surgery remains the treatment of choice and laparoscopic approach offers numerous benefits. We report our personal experience in elderly patients operated on for colorectal cancer with laparoscopic resection.

PATIENTS AND METHODS

From January 2003 to September 2013, out of 160 patients aged 65 years or older and operated with minimally invasive techniques, 30 cases affected by colorectal cancer and operated on with laparoscopic approach were analyzed in this study.

RESULTS

Male/female ratio was 1.35 and mean age 72 years. Constipation, weight loss, anemia and rectal bleeding were the most commonly reported symptoms. Lesions involved descending-sigmoid colon in 53% of cases, rectum in 37% and ascending colon in 10%. Among laparoscopic colo-rectal operations laparoscopic left colectomy was the most frequently performed, followed by right colectomy, abdominoperineal resection and Hartmann procedure. Operative times ranged from 3 to 5 hours depending on surgical procedure performed. Mean hospital stay was 6 days (range 4-9). Conversion to open approach occurred only in a case of laparoscopic right colectomy (3%) for uncontrolled bleeding. A single case of mortality was reported. In two cases (7%) anastomotic leakage was observed, conservatively treated in one patient and requiring reoperation in the other one.

CONCLUSIONS

Laparoscopic colorectal surgery is feasible and effective for malignancies in elderly population offering several advantages including immunologic and oncologic ones. However an experienced surgical team is essential in reducing risks and complications.

Late results after splenectomy in adult idiopathic thrombocytopenic purpura

Background:

We performed a retrospective study on patients with idiopathic thrombocytopenic purpura (ITP) to evaluate the response to splenectomy in relation to preoperative platelet count.

Materials and Methods:

Two groups of patients operated on with laparoscopic or open splenectomy for ITP, with a platelet count ≤30,000/μL (study group: 22 patients) and >30,000/μL (control group: 18 patients), respectively, were compared. The two groups were homogeneous in relation to age, sex, length of preoperative steroid therapy, and time interval between diagnosis and surgery (Student t test with P > .1). The results of surgery were evaluated at one year after splenectomy. Positive response to surgery, according to the American Society of Hematologic Guidelines, was considered in patients with a postoperative platelet count ≥100,000/μL or in patients with a postoperative platelet count ≥30,000/μL and a twofold increase in platelet count from baseline, in the absence of bleeding.

The postoperative platelet count increase rate was statistically related to preoperative platelet count in both the study and control groups. Statistical analysis was performed using the Student's t test for independent sample and the Pearson correlation in a 2-tailed test.

Results:

No relationship between preoperative platelet count and postoperative platelet percent increase was observed in the control group (r = –0.41; P = .089), whereas a significant negative correlation (r = –0.68; P = .0004) was found in the study group.

Conclusions:

A higher increase of postoperative percent platelet count may be predicted in patients with a low preoperative platelet count.

Laparoscopic splenectomy coupled with laparoscopic cholecystectomy

Background and Objectives:

The aim of this study was to evaluate the results of laparoscopic surgery performed for coexisting spleen and gallbladder surgical diseases.

Methods:

Between May 2004 and October 2012, 12 patients underwent concomitant laparoscopic splenectomy and cholecystectomy. Indications for surgery included idiopathic thrombocytopenic purpura in 5 patients, hereditary spherocytosis in 4 patients, and thalassemia intermedia in 3 patients.

Results:

The mean operative time was 100 minutes (range, 80–160 minutes), and the blood loss ranged from 0 to 150 mL (mean, 50 mL). The mean longitudinal diameter of the spleen was 14 cm. One patient required conversion to open procedure. An accessory spleen was detected and removed in one case. The mean length of hospital stay was 5 days. No deaths or other major intraoperative and/or postoperative complications occurred.

Conclusion:

Provided that the technique is performed by an experienced surgical team, concomitant laparoscopic splenectomy and cholecystectomy is a safe and feasible procedure and may be considered for coexisting spleen and gallbladder diseases.

Subcutaneous cervical emphysema and pneumomediastinum due to a diastatic rupture of the cecum

Pneumomediastinum usually occurs after esophageal or chest trauma. Subcutaneous cervical emphysema as a presentation of non-traumatic colonic perforation following colorectal cancer or diverticulitis, is very rare. We report a case of a patient with rectal cancer who developed a diastatic cecum retroperitoneal perforation with a secondary pneumomediastinum and cervical emphysema. The patient was in treatment with a neoadjuvant chemo-radiotherapy for a low rectal cancer. Treatment consisted in an emergency right hemi-colectomy with ileostomy and performance of distal colonic fistula. The Authors discuss the occurrence of pneumomediastinum and cervical emphysema complicating rectal cancer, pointing out ethiopathogenesis, clinical presentation, diagnosis and treatment. The importance of performing a diverting colostomy when neoadjuvant chemotherapy is scheduled in patients with stenotic rectal cancer, although not clinically occluded.

The use of surgical drains in laparoscopic splenectomies Consideration on a large series of 117 consecutive cases

BACKGROUND DATA

The use of surgical drains after traditional splenectomy has been largely debated and several Authors have been unfavorable to their use. With the advent of laparoscopic splenectomy, their role has been re-discussed. The increased risk of undetectable pancreatic, gastric or colon injury in challenging laparoscopic removal of the spleen have induced some surgeons to reconsider the advantages related to their use.

METHODS

One hundred seventeen consecutive cases of laparoscopic splenectomy with routine use of surgical drains have been reviewed. Indications for surgery, length of operations, post-operative day of drain removal, post-operative complications were retrospectively analyzed.

RESULTS

Laparoscopic splenectomy was performed for idiopathic thrombocytopenic purpura in 77 patients (65,8%), splenic lymphoma in 11 (9,4%), hereditary spherocytosis in 12 (10,2%), β-thalassemia in 6 (5.1%), other diseases in 11 (9,4%) cases. Conversion to open surgery was necessary in 11,1% of cases. Drains were removed 2-3 days after surgery in 95,8%, within 10 days in 3.4%, within 2 months in 0,8% of cases. In 2 cases a post-operative bleeding, detected through the drainage, required re-operation. One patient with myelofibrosis and massive splenomegaly developed a late post-operative subphrenic abscess, successfully treated by a percutaneous drainage.

CONCLUSIONS

In Authors' experience, the use of drains after laparoscopic splenectomy helped detect early post-operative bleeding. Surgical drains could reduce the incidence of fluid intra-abdominal collections and infections. Their use should be recommended in the laparoscopic approach, especially in technically demanding surgical procedures.

KEY WORDS

Laparoscopy, Surgical drainage, Splenectomy.

Feasibility and accuracy in performing complete mesocolic excision during laparoscopic left colectomy

Laparoscopic colorectal surgery for cancer is nowadays performed in several referral centers and has been gaining increasing interest for treatment of colo-rectal cancer. After the introduction of complete mesorectal excision for rectal cancer, complete mesocolic excision has been advocated as an essential surgical step to improve oncologic results for patients with colon cancer. Complete mesocolic excision is a crucial step of hemicolectomy, and consists in the total removal of the mesocolon and its lymph nodes with high ligation of main mesenteric arteries and veins. In laparoscopic surgery, magnification of the images and gas dissection might probably improve the precision and safety of this surgical step. In this paper, the Authors reviewed the Literature and discussed on the feasibility and accuracy of complete mesocolic excision performed during laparoscopic left colectomy for cancer in a preliminary series.

KEY WORDS

Colic lymph nodes, Laparoscopic left hemicolectomy, Mesocolon excision.

A rare case of myeloid sarcoma presenting as anal fissure

Myeloid sarcoma is a tumor composed of myeloblasts occurring at an extramedullary site. It may develop in patients with acute myeloid leukemia, myeloproliferative or myelodysplastic syndrome, sometimes preceding onset of the systemic disease. Frequent sites of myeloid sarcoma are bones or various soft tissues. Gastrointestinal involvement is very rare. We report a unique case of myeloid sarcoma presenting as a painful anal fissure, in a patient with a history of acute myeloid leukemia. The diagnosis was achieved by a surgical excisional biopsy and immunoistochemical staining.

Laparoscopic-endoscopic rendez-vous resection of iuxta-cardial gastric GIST

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and they often require a surgical removal. Gastrointestinal stromal tumors can originate from any part of the gastrointestinal tract but gastric location is the most common. In the past the risk of rupture of pseudocapsula and peritoneal dissemination have discouraged surgeons from making a minimally invasive surgical treatment. Recently laparoscopic wedge resection has been proposed. Performance of this mini-invasive technique is however difficult in some gastric location of gastrointestinal stromal tumors, such as iuxta-cardial region. The Authors report and discuss a new technique they used to remove a gastrointestinal stromal tumor located just below the cardia, using a rendez-vous endoscopic and laparoscopic technique.

Long-term results after splenectomy in adult idiopathic thrombocytopenic purpura: comparison between open and laparoscopic procedures

BACKGROUND

Only a few studies have addressed long-term results comparing laparoscopic and open splenectomy in idiopathic thrombocytopenic purpura (ITP). We analyzed the 1-year results comparing age, sex, length of preoperative steroid therapy, diagnosis-to-splenectomy interval, and preoperative platelet count in relation to postoperative response after open and laparoscopic splenectomy.

SUBJECTS AND METHODS

Data collected from two groups, treated by laparoscopic and open splenectomy, respectively, of 20 patients each were retrospectively reviewed. Positive response to splenectomies, evaluated according to the International Working Group guidelines reported by the American Society of Hematology, was statistically related through Student's t test and the Pearson correlation test to the above-mentioned factors.

RESULTS

Positive response to splenectomy was observed in 80% and 85% of patients, respectively, in the laparoscopic and open groups (P > .10). No statistical differences were observed comparing each of the studied factors between laparoscopic and open splenectomy responder patients (P > .10). When percentage increase of postoperative platelet count was related to diagnosis-to-splenectomy interval, a positive correlation was found in the laparoscopic group (r = 0.544, P < .05). In addition, a significant negative correlation in both groups was observed comparing preoperative platelet count and percentage postoperative platelet increase, with a greater increase of postoperative platelet count in patients with a lower preoperative platelet count (laparoscopic group, r = -0.663; open group, r = -0.656; P < .01).

CONCLUSIONS

In this series long-term results after laparoscopic splenectomy in ITP patients were as effective as after the open approach. Higher postoperative platelet percentage increase was achieved in both groups in patients with a lower preoperative platelet count. Finally, laparoscopic splenectomy in this study seems to be superior to the open approach in patients with a longer diagnosis-to-splenectomy interval.

Polyp of the cecum. Laparoscopic-assisted polypectomy

The Authors discuss on a laparoscopic-assisted approach for excision of a sessile villous adenomatous polyp of the cecum, unresectable by endoscopy. Because of the large implant of the polyp, endoscopic polypectomy was considered at high risk and a surgical laparoscopic procedure was scheduled for removal of the lesion. After right colon mobilization, an intraoperative endoscopy confirmed the location of th polyp in the posterior wall of the cecum, closed to the ileo-cecal valve. A small 10 cm laparotomy, through which the cecum was pulled out the abdominal cavity, was performed. Then, a minimal colotomy along the intestinal taenia was carried out to allow a safe and complete excision of the polyp. This laparoscopic approach differs from the other laparoscopic-assisted methods reported in the Literature since it provides at the same time the postoperative advantages associated with minimal access surgery and a safe oncological removal of the polyp with low risks of complications.

Laparoscopic treatment of mucinous adenocarcinoma of jejunum associated with celiac disease. Case report

Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

Splenic hilum management during laparoscopic splenectomy

BACKGROUND

The division of the splenic hilum is the most delicate step during laparoscopic splenectomy. An incorrect approach could lead to a series of related complications. Aim of the study was to report authors' personal experience in a series of 107 laparoscopic splenectomies where the splenic hilum was approached by means of stapling device. A possible relationship between instruments used to divide the splenic artery and vein and complications was analyzed.

METHODS

Laparoscopic splenectomy was performed in 107 cases at authors' institution between 1998 and January 2011. In all the patients, splenic hilum was approached by means of vascular stapler.

RESULTS

Indications for the spleen removal mainly were hematologic disorders. Associated surgical procedures were performed in 32 cases. Among the 13 patients who required a conversion to open splenectomy, only in 3 cases the reason was related to the hilum management. Postoperative complications included portal vein thrombosis in 3 cases, pancreatic fistula in 1 case, and bleeding, requiring reintervention, in 2 cases.

CONCLUSIONS

The use of the stapling device is a safe and effective method to approach the splenic hilum during laparoscopic splenectomy. In experienced hands it showed a low rate of related complications.

Laparoscopic splenectomy in patients under the age of eighteen. Experience in 18 cases

BACKGROUND

Pediatric surgery is now in the forefront of minimal access procedures. Although pediatric surgeons have been skeptic about laparoscopic splenectomy, recently minimally invasive approach for spleen removal has been revaluated also in young patients. Purpose of this study was to report Authors' personal experience in patients under eighteen who underwent laparoscopic splenectomy. Results of the procedure were evaluated.

PATIENTS AND METHODS

A retrospective review was undertaken in 18 splenectomised patients under the age of eighteen. Indications were hereditary spherocytosis in 10 patients, β-thalassemia in 4, idiopathic thrombocytopenic purpura in 3 and a splenic cyst in 1 child.

RESULTS

No intra-operative complications occurred. No conversion to open surgery was reported. During the follow-up one case of portal vein thrombosis, treated by medical therapy, was encountered and no other postoperative complications were observed.

CONCLUSIONS

Laparoscopic approach has to be preferable for all those children undergoing spleen surgery. In experienced hands, it is of beneficial effects with a very reasonable rate of complications.

Portal vein thrombosis after laparoscopic and open splenectomy

INTRODUCTION

Portal vein thrombosis (PVT) could be a life-threatening complication after splenectomy if not diagnosed promptly and treated properly. Risk factors of PVT are not completely clarified. Spleen size and underlying hematologic diseases are main potential risk factors for this complication. Laparoscopic surgery might increase the risk of developing PVT, as it reduces the blood flow in the portal system due to the pneumoperitoneum but, on the other hand, it seems to be associated with less postoperative modifications of coagulation parameters than open surgery, thus preventing PVT itself. The authors reviewed their series on open and laparoscopic splenectomies, pointing out their experience on PVT and discussing their surveillance and prophylaxis programs to prevent this complication.

MATERIALS AND METHODS

In this series, the authors report their experience on postsplenectomy PVT in 162 patients who have been splenectomised (102 operated on laparoscopically and 60 by open surgery).

RESULTS

PVT was clinically observed in 1 case out of 60 open splenectomies and in 3 cases out of 102 laparoscopic procedures. Patients were treated with conservative anticoagulation therapy. In one case, additional ileal resection was needed. Mortality was 0%.

CONCLUSION

Low-molecular-weight heparin should be administered to all patients who have been splenectomised, especially if they are at high risk of PVT. If symptoms appear, patients need to be treated with high-dose heparin followed, after at least 3 weeks, by oral anticoagulant therapy.

Laparoscopic surgery in the elderly: personal experience in 141 cases

INTRODUCTION

As life expectancy increases, the number of elderly patients presenting with surgically correctable diseases will rise as well. For advantages, which are well recognized in young patients, laparoscopic surgery has been proposed also for older patients. Because of underlying chronic diseases, however, elderly patients have been considered at high risk for the laparoscopic approach. Several studies have pointed out the risks related to cardiac, respiratory, or general comorbidities when elderly patients are proposed for laparoscopic treatment of their surgical disease.

PATIENTS AND METHODS

In this study, we reported our experience in 141 patients older than 65 years who were submitted to laparoscopic procedures for several indications. According to American Society of Anesthesiologists (ASA) score, patients were classified as ASA I in 70.9% of cases, ASA II in 27.6%, and ASA III in 1%.

RESULTS

No mortality has been reported. Conversion rate was 5.3% for bleeding in 4 cases or intraoperative hypotension in 2 cases. Mean hospital stay was 5 days. Postoperative complication was reported in 1 case and consisted of a hearth attack.

CONCLUSIONS

Laparoscopic surgery in the elderly is a safe procedure, if preoperative selection of the patients is accomplished. An experienced surgical team and multidisciplinary approach are mandatory.

Laparoscopic left colectomy: from the perfect knowledge of surgical anatomy to the proper surgical technique

Laparoscopic colo-rectal surgery has been increasingly accepted and performed in several surgical centres. However, there are still concerns about the intra-operative risks and therefore on the safety of the procedure especially during the learning curve. As a matter of fact, in approximately one third of laparoscopic colo-rectal procedures, an intra-operative complication, mainly bleeding or iatrogenic injuries, may occur. In this paper, according to our experience, we analyse step by step the surgical technique of the laparoscopic left colectomy and evaluate the technical difficulties and complications in order to avoid them.

How to prevent intraoperative risks and complications in laparoscopic splenectomy

Since its introduction in 1992 laparoscopic splenectomy (LS) has become the technique of choice for surgical removal of the spleen in several centres. The procedure, however, is associated with risks and complications, either during surgery or in the postoperative phase. Although the incidence of intraoperative complications is unknown, intraoperative risks in patients undergoing laparoscopic splenectomy are not uncommon. In this article, we reviewed the literature on risks and complications during LS, and we point out, based on our personal series and on the experiences reported by other Authors, how to prevent, whenever possible, these complications.
