Laparoscopic Single-Port Versus Traditional Multi-Port Laparoscopic Cholecystectomy.

BACKGROUND AND OBJECTIVES: Safety, efficacy, and costs are still debated issues in single-port laparoscopy. The aim of the study was to compare clinical outcomes and hospital costs for conventional 4-port laparoscopic cholecystectomy (4PLC) and single-port laparoscopic cholecystectomy (SPLC) performed at a single institution. METHODS: A series of 40 SPLC patients operated on from October 2016 to May 2017 were compared to a hystorical series of 40 4PLC patients. Primary endpoints were the operative time, blood loss, postoperative pain, analgesia requirement, length of stay, and morbidity. Secondary endpoints were the operative costs and total hospital costs. RESULTS: No patient required surgical conversion in both groups. Duration of surgery was significantly longer in the SPLC group. Length of hospitalization was shorter for patients operated on by SPLC (1.9 ± 0.9 vs 2.3 ± 1.2 days; P = .104). According to visual analogue scale evaluation, the pain profile was similar. Minor postoperative complications were present in 12.5% of the SPLC group and 2.5% in 4PLC group (P = .200). The total hospitalization costs associated with SPLC procedure were lower compared to standard 4PLC procedure. As regards the disposable operating room equipment costs, a statistically significant difference in favor of SPLC technique was found. CONCLUSION: SPLC has shown relevant procedure and postoperative outcomes when compared to traditional 4PLC. The technique has proved to be promising even in cases of acute cholecystitis considered to date a relative contraindication. Further studies are needed to confirm its safety and feasibility in this setting. In contrast with the current evidence of increased costs for the single-port technique, a reduction of material and hospitalization costs was experienced in our study.

Elective surgery for ulcerative colitis, ileo-rectal anastomosis or restorative proctocolectomy An Update.

BACKGROUND: Despite advances in the medical management of Ulcerative Colitis (UC), surgery is required in about a third of patients. AIMS AND METHODS: A review of the literature of the last 20 years was conducted in order to analyze the results of Ileo-Rectal Anastomosis (IRA) and of Ileal Pouch-Anal Anastomosis (IPAA) in the treatment of mild-to-moderate UC. Postoperative complications, functional results and the risk of cancer were analyzed in each of the two groups of patients. RESULTS: In IRA group postoperative morbidity is low, varying from 8 to 28%. The risk of urinary and sexual dysfunction are rare and fertility rates are higher, compared to IPAA. The cumulative probability of success (working IRA) is 84% at 5 years and 51-69% at 10 years. The postoperative morbidity of IPAA is higher; dehiscence and pelvic sepsis were observed respectively in 9.5% and in 5.5%. A sexual dysfunction is present in 3.4%. In 18.8% occurs pouchitis. The risk of failure of the pouch is 6.8% and increased to 8.5% after 5 years. The risk of cancer is higher after IRA than after IPAA, with a cumulative risk at 20 years of 6-14% and 4.2% respectively. DISCUSSION: The choice between IPAA or IRA is based upon patient's preference and clinical criteria (malignancy or sphincter injury). IPAA, intervention of choice, is burdened by a higher rate of complications, such as anastomotic leak with pelvic sepsis and subsequent functional pouch failure, pouchitis, infertility in young women, lesions of the pelvic nerves and portal vein thrombosis. There have been reports of cancer not only in the anal transitional zone, but also in the same pouch, either after mucosectomy that after stapled anastomosis. IRA is less invasive than IPAA and postoperative complications are lower. Does not require dissection of the pelvic and presents no risk of injury of the nerves of the urogenital sphere. The long-term results of the IRA are generally satisfactory and most of the patients stated that after the intervention improve both the health status and quality of life. CONCLUSION: Today IPAA is the gold standard. The IRA is indicated in selected patients where they meet the following requirements: normal sphincter tone, absence of severe perineal disease, rectum does not actively involved by the disease, absence of dysplasia or cancer. It is also indicated in patients who refuse an ileostomy and it can be proposed as a possible interim procedure in young women, because it does not need a pelvic dissection and because the risk of infertility is minimal or absent when compared to IPAA. Because the risk of cancer is higher, patients undergoing IRA must be adequately informed about the risk, as well as recurrent proctitis, also of cancer, and must fully understand the need for surveillance and accept at least annual endoscopy with rectal biopsies; if these conditions are not met, patients should not be candidates for IRA.

Adenocarcinoma Arising from Perianal Fistulizing Crohn's Disease.

Perianal fistula is a very debilitating event and a cause of morbidity in patients with Crohn's disease (CD). Its malignant transformation is very rare with an incidence of around 0.004-0.7$. Presence of disease in the colon and rectum is the major risk factor for the development of a perianal fistula. In this report we show a case of adenocarcinoma arising from a perianal fistulizing CD. This type of tumor is highly aggressive, difficult to diagnose, and has a rather poor prognosis. The different neoplastic transformations and the different types of tumors that may appear in patients with CD, especially at the colorectal level or at the level of an eventual anastomosis, are to date well documented and described in the literature, while there is a lack of information and of treated cases concerning the occurrence of cancer at the level of a fistula. Due to the rarity of cases, we tried to identify the most frequent and important risk factors: sex, duration of disease, age at diagnosis, and the history of the fistula.

Laparoscopic "double-port" splenectomy. A new minimally-invasive option in a giant spleen.

INTRODUCTION: In case of massive splenomegaly, laparoscopic splenectomy (LS) becomes challenging, uncomfortable and risky both for the surgeon and for the patient. As a consequence of ongoing research to obtain efficient and cheaper "scarless surgery", single-port technique and hand-assisted devices were developed and improved in this field. PRESENTATION OF CASE: We present the clinical case of a patient affected by idiopathic myelofibrosis (MF) and splenomegaly who was admitted to our Department to perform a splenectomy for a suspected 5-cm splenic lesion. DISCUSSION: The splenic longitudinal diameter measured 26 cm. The patient underwent splenectomy by laparoscopy, combining a single-port access and a gel-port device. The operation was completed laparoscopically. The operating time was 220 min and the estimate blood loss was 100 ml. The patient was discharged at 11 post-operative day in overall good conditions. Upon pathological analysis the splenic lesion was a localization of diffuse large B-cell Lymphoma in the context of MF. CONCLUSION: this novel "hybrid technique" of splenectomy, combining the advantages of reduced number of abdominal incisions of the single-port technique to those of the hand assistance, is feasible in massive splenomegaly with good results. Furthermore, the use of the sovrapubic retrieval incision as the introduction site for the hand assisted device is convincing, since it's useful for both tasks. Further studies with large casuistries are necessary to confirm the effectiveness of the technique.
