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.

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.

Intraoperative Pyloric Interventions during Oesophagectomy: a Multicentre Study.

BACKGROUND: Denervation of the pylorus after oesophagectomy is considered the principal factor responsible for delayed gastric emptying. Several studies have attempted to delineate whether surgical or chemical management of the pylorus during oesophagectomy is of benefit, but with conflicting results. The aim of this multicentre study was to assess whether there was any difference in outcomes between different approaches to management of the pylorus. METHODS: A prospectively maintained database was used to identify patients who underwent oesophagectomy for malignancy. They were divided into separate cohorts based on the specific pyloric intervention: intra-pyloric botulinum toxin injection, pyloroplasty and no pyloric treatment. Main outcome parameters were naso-gastric tube duration and re-siting, endoscopic pyloric intervention after surgery both as in- and outpatient, length of hospital stay, in-hospital mortality and delayed gastric emptying symptoms at first clinic appointment. RESULTS: Ninety patients were included in this study, 30 in each group. The duration of post-operative naso-gastric tube placement demonstrated significance between the groups (p = 0.001), being longer for patients receiving botulinum treatment. The requirement for endoscopic pyloric treatment after surgery was again poorer for those receiving botulinum (p = 0.032 and 0.003 for inpatient and outpatient endoscopy, respectively). CONCLUSION: We did not find evidence of superiority of surgical treatment or botulinum toxin of the pylorus, as prophylactic treatment for potential delayed gastric emptying after oesophagectomy, compared to no treatment at all. Based on our findings, no treatment of the pylorus yielded the most favourable outcomes.

Case Report: Spontaneous cholecystocutaneous fistula, a rare cholethiasis complication.

One of the most unusual complications in cholethiasis is spontaneous cholecystocutaneous fistula, which has only been reported a few times in the literature.  We report the case of a 76 year old man who presented with a right hypochondrium subcutaneous abscess, with pain evoked through palpation.  No comorbidity in the patient's medical history were noted.   Confirmation of cholecystocutaneous fistula was made using the proper diagnostic process, which is computed tomography with contrast media, followed by hepatobiliary MRI. This confirmed the presence of a fistulous pathway between the gallbladder and the skin.  The patient underwent cholecystectomy surgery and open laparotomy with en block aponeurotic muscle, skin and fistula orifice excision.

Laparoscopic Colorectal Surgery for Cancer: What Is the Role of Complete Mesocolic Excision and Splenic Flexure Mobilization?

Laparoscopic colorectal surgery for cancer is nowadays routinely performed worldwide. After the introduction by Heald of total mesorectal excision for rectal cancer, also a complete mesocolic excision has been advocated as an essential surgical step to improve oncologic results in patients with colon cancer. The complete removal of mesocolon with high ligation of the main mesenteric arteries and veins and the mobilization of splenic flexure are well-known but still debated in western surgical society. The authors reviewed the literature and outlined the rationale and the results of splenic flexure mobilization and complete mesocolic excision in laparoscopic surgery for colorectal cancer.

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%), ß-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.

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.

Totally laparoscopic repair of an ileal and uterine iatrogenic perforation secondary to endometrial curettage.

Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage. Abdominal X-ray shows signs of pneumoperitoneum. Emergency diagnostic laparoscopy was performed and a uterine-ileal perforation was identified. Repair was accomplished by a totally laparoscopic intracorporeally suturing of the 2 breaches. Postoperative course showed only a delayed ileus and the patient was discharged after 5 days with no complications. When acute abdomen arises following uterine biopsy, a potential iatrogenic intestinal laceration always has to be ruled out. Laparoscopic approach is a quick and safe technique in these cases. Totally laparoscopic primary closure of the iatrogenic ileal laceration may be accomplished with low morbidity.

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.

Solitary subcutaneous hydatid cyst: review of the literature and report of a new case in the deltoid region.

BACKGROUND: Solitary subcutaneous hydatid cyst is not frequent and the only symptom is generally a silent growing mass. Total excision remains the mainstay of treatment. Aim of the study was to present a case surgically treated and perform a statistical analysis reviewing previous published works in order to define a correct approach to diagnosis and treatment. METHODS: 264 documents from Medline database were considered for primary subcutaneous hydatid cyst cases. Data concerning geographic region, gender, age, job, location, evolving time, history and physical, mobility, diameter, laboratory, imaging, locularity (uni- or multilocular cyst), fine-needle aspiration, preoperative diagnosis, neoadjuvant chemotherapy, treatment, spillage, adjuvant therapy, follow-up and recurrences were ordered in a database and analysed performing t-test, Fisher's test and Pearson's test. RESULTS: 23 cases, included ours, resulted suitable for our study. Lower extremities were involved in most cases (60.9%) and the thigh represented the most common site (34.8%), whereas upper extremities were the rarest location (8.7%). Patients with head and neck located cysts were younger than those with upper extremities cysts (P=0.037). Patients who underwent multiple imaging approach received a significantly correct first diagnosis (P=0.001) and ultrasonography, unlike other techniques, appeared to be essential (P=0.013). CASE REPORT: A 68-year-old man who lived and worked in his farm in Sicily (Italy) presented with a 30-year-growing mass in the deltoid region measuring 10 cm. Ultrasonography and magnetic resonance imaging strongly suggested hydatid cyst. Therefore the cyst was excised and pathology confirmed the diagnosis. CONCLUSION: Solitary subcutaneous hydatid cyst must always be considered in the differential diagnosis of silent growing mass in soft tissues. History and physical associated with ultrasound and magnetic resonance imaging are sufficient to achieve a correct preoperative diagnosis.

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.

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.

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.
