Oral HPV infection clearance and acquisition after nonavalent vaccination in men who have sex with men and transgender women: a prospective analysis.

Oral HPV infection is the main risk factor for the development of oropharyngeal carcinoma. Men who have sex with men (MSM), especially if living with HIV (PLWH), are at increased risk of infection and consequently of cancer development. Aim of this study is to evaluate the impact of nonavalent vaccine on oral HPV infection in a cohort of MSM and transgender women (TGW). This prospective study included all MSM and TGW who started nonavalent HPV vaccination from May 2019 to September 2021. Oral rinse was collected before each vaccine administration and after six months of follow up. Descriptive statistics were used. Kaplan Meier probability curves and Cox regression models for HPV acquisition and clearance were calculated. The analysis included 211 individuals (202 MSM and 9 TGW). PLWH were 138 (65.4%). Baseline oral rinse was positive in 30 subjects (14.2%). Positivity rate did not change over time (p = 0.742), even when restricting the analysis only to high-risk genotypes (p = 0.575) and to genotypes covered by vaccine (p = 0.894). The risk to acquire HPV infection was 12.8% at one year and 33.4% at two years after vaccination. The probability to clear the infection was 67.6% at one year and 87.9% at two years. HIV infection had no impact on vaccine efficacy. Age above 45 years was the only factor associated to HPV acquisition (aHR 4.06, 95% CI 1.03-15.98, p = 0.045). Prevalence of oral HPV infection was higher in PLWH, but HIV had no impact on viral clearance or acquisition after vaccination.

Parastomal hernia: an overview.

Parastomal hernia (PH) is one of the most frequent ostomy complications, and the reported incidence in the literature is highly variable. As highlighted by the Association of Stoma Care Nurses UK, this complication develops mainly in children and older men over 70, but many predisposing factors are related to the individual patient and surgery. There is no standardised system for assessing PH. The main assessment techniques include objective examination, ultrasound scan and computed tomography. Prevention is based on various interventions by surgeons and stoma care nurses (SCNs). The SCN's primary interventions include accurate patient evaluation, pre-operative ostomy siting, education about body weight management and advice on appropriate exercises. The treatment of PH can be conservative or surgical, and the choice is based on the patient's clinical condition. Ostomy can significantly impact on a patient's quality of life (QoL), and the presence of PH can further aggravate the situation. This overview of PH considers the incidence, aetiology, prevention, treatment and impact on QoL.

Prevalence and Risk Factors of Anal HPV Infection in MSM Living With HIV: Identifying the Target Groups to Prioritize for Immunization.

BACKGROUND: Aims of this study are assessing prevalence of anal human papillomavirus (HPV) genotypes in male who have sex with men (MSM) living with HIV over a period of 5 years and determining risk factors for anal infection from high-risk (HR) HPV genotypes or included in vaccine Gardasil 9. SETTING: Time-trend, monocentric study on MSM living with HIV who underwent HPV test at anal site from 2015 to 2019. METHODS: Anal swabs were processed by multiplex real-time polymerase chain reaction to detect HPV genotypes. The Cochran-Armitage test was used to assess linear trend in HPV prevalence over time and logistic regression models to estimate risk factors. RESULTS: Of the 1352 MSM living with HIV, 168 (12%) were not infected by any HPV genotypes and only 6 were infected with a maximum of 6 genotypes; prevalence of HR-HPV genotypes or those included in the 9-valent vaccine remained stable over time. At multivariable analysis, the risk of carrying at least 1 genotype classified as HR or included in Gardasil 9 was associated with younger age [adjusted odds ratio (aOR) for younger than 30 years vs older than 45 years (95% confidence interval) 2.714 (1.484 to 4.961), P = 0.001, and 1.868 (1.141 to 3.060), P < 0.013, respectively] and a history of gonorrhea [aOR 2.118 (1.100 to 4.078), P = 0.025, and 1.785 (1.056 to 3.018), P = 0.031, respectively]. CONCLUSION: Our findings suggest that prevalence remained stable over time and that all MSM with HIV would benefit from Gardasil 9 immunization, particularly the youngest and those with a prior gonococcal infection.

Doppler-guided hemorrhoidal dearterialization with laser (HeLP): indications and clinical outcome in the long-term. Results of a multicenter trial.

BACKGROUND: Doppler-guided hemorrhoidal laser procedure consists of sutureless closure of terminal branches of the superior hemorrhoidal artery by laser energy. Clinical results of patients treated with this procedure were analyzed at the completion of 2-year follow-up. Primary endpoint was resolution of symptoms and secondary endpoints were recurrence rate, type of recurrences, re-operation rate, and potential predictive factors for failure. METHODS: Bleeding was assessed on a score from 0 to 4 (none = 0; < 1/month = 1; 1/week = 2; > 1/week = 3; 3-4/week = 4), frequency of hemorrhoid-related symptoms with a score of 0-3 (2/year = 1; 3-5/year = 2; < 5/year = 3). Constipation and fecal incontinence were assessed by means of validated scores. Quality of life and pain at defecation were assessed using a visual analog scale of 0-10 (0 = worst possible-10 = best possible quality of life and 0 = no pain-10 = worst pain imaginable, respectively). Recurrence rate and need for re-operation were reported. Potential predictive factors of failure were analyzed by means of univariate analysis. RESULTS: Two-hundred-eighty-four patients (183 males, 101 females; mean age: 47.5 years) were included in the trial; 8 patients were lost at follow-up. Analysis of 276 patients who completed the 2-year follow-up showed an overall resolution of symptoms in 89.9% (248/276) of patients. Statistically significant improvement of quality of life, pain reduction, bleeding and frequency of acute symptoms were reported. Of 28 patients with persistent or recurrent symptoms, 12 had pain (4.35%), 10 had bleeding (3.6%) and 6 had increasing prolapse at defecation (2.2%). Eleven out of twenty-eight patients required additional surgery. Constipation and III-IV grade hemorrhoids were associated with statistically significant higher failure rates (p = 0.046 and 0.012, respectively). Better results were reported in patients reporting preoperative high-grade pain at evacuation. CONCLUSIONS: The Doppler-guided hemorrhoidal laser procedure showed efficacy at long-term follow-up. It can be considered as 'first-line' treatment in patients with low-grade hemorrhoids suffering from bleeding, pain and recurrent acute symptoms in whom conservative treatment failed.

Hemorrhoid laser procedure (HeLP) for second- and third-degree hemorrhoids: results from a long-term follow-up analysis.

We aimed to analyze the results of 5-year consecutive use of the hemorrhoidal laser procedure (HeLP) in patients with second- to third-grade hemorrhoids with minimal or moderate mucosal prolapse. A total of 189 patients were treated between April 2012 and October 2017. We reported perioperative complications, postoperative pain, improvement of hemorrhoids grade, and relapse of hemorrhoidal disease (HD). Improvement of symptoms was assessed using the Patient Global Improvement (PGI) Scale. No severe intraoperative complications were observed. The median follow-up was 42 months (range 6-62 months). Pain after surgery was absent in 94% of patients. No cases of rectal tenesmus or alterations of defecation habits were reported. Symptoms and HD improvement reached a "plateau" at 3 to 6 months following surgery. We observed a significant decrease in HD degree, occurrence of bleeding, pain, itching, and acute HD. Complete resolution of HD was reported in > 60% of patients 1 year after surgery. The individual level of improvement in symptoms was consistent (very much and much improved, according to PGI-I score) for about 90% of patients during the follow-up. This study confirmed that the HeLP is a safe, painless, and effective procedure for the treatment of HD in selected cases.

HPV 16 and 18 contribute to development of anal dysplasia in HIV infection irrespective of gender and sexual orientation.

OBJECTIVES: The aim of the present study was too investigate prevalence and persistence of human papilloma virus (HPV) and cytological abnormalities (CAs) in the anal swabs of people living with HIV (PLWH): men who have sex with men (MSM), men who have sex with women (MSW) and women (W). METHODS: Between March 2010 and January 2019, an anal swab for cytological and HPV genotyping tests was offered to all PLWH attending our clinic. Logistic regression analysis was conducted to identify predictors of infection. RESULTS: In all, 354 PLWH were screened: 174 MSM, 90 MSW and 61 W. Prevalence of at least one high-risk (HR) HPV was higher in MSM (91%) and W (85%) than in MSW (77%) (P < 0.05). Cytological abnormalities were found in 21.1% of the entire population. At multivariable regression analysis a lower risk for HPV infection was found for W than for MSM [odds ratio = 0.24 (95% confidence interval: 0.115-0.513)] and for MSW than for MSM [0.37 (0.180-0.773)] and there was a significantly higher risk of CAs in PLWH with HPV 16 and 18 [3.3 (1.04-10.49)]. A total of 175 PLWH (103 MSM, 33 MSW and 26 W) had at least one follow-up visit (T1) after a median (interquartile range) follow-up of 3.6 (2.1-5.7) years. The acquisition rate of HR-HPV was high, with 66.7% of PLWH negative for HR-HPV at T0 who became positive at T1 (P < 0.001). The prevalence of CAs was stable (20.6%). A significant association between CAs at T1 and persistence of HPV-16 and/or 18 was found (P < 0.05). CONCLUSIONS: HPV 16 and 18 are associated with the presence and development of CAs irrespective of sexual orientation.

Risk factors and clinical characteristics of early-onset colorectal cancer vs. late-onset colorectal cancer: a case-case study.

BACKGROUND AND OBJECTIVES: Early-onset colorectal cancer (eoCRC), defined as colorectal cancer (CRC) before the age of 50 is increasing in incidence. We evaluated exogenous and endogenous risk factors, and clinical features of eoCRC, compared to late-onset CRC (loCRC). METHODS: In this retrospective case-case study, patients were prospectively enrolled from 2015 to 2018. We collected clinical features (age, sex, time from symptom onset to diagnosis, symptoms, family history, smoking and alcohol habits, diabetes, BMI, and genetic analysis) and tumor characteristics. Independent risk factors for eoCRC and odds ratios (ORs) were identified. RESULTS: Fifty-four eoCRCs and 494 loCRCs were enrolled. Patients with eoCRC experienced longer delay time from symptom onset to diagnosis: 40.7% were diagnosed within 6 months from symptoms onset, compared to 85.6% of patients with loCRC (P < 0.0001). They differed for sex, presence of symptoms, family history, smoking habit, alcohol intake, and BMI. Rectal localization was more closely associated with eoCRC (64.8%) than loCRC (34.5%, P < 0.0001). Family history of CRC was associated with eoCRC (OR = 8.8). When family history occurred with hereditary cancer syndromes, the OR for eoCRC increased to 21. CONCLUSION: In young adults with alarming symptoms, CRC must be suspected to avoid delay time from symptom onset to diagnosis and genetic risk assessment has to be evaluated. Smoking habits, alcohol intake, and BMI are not associated with eoCRC.

Impact of sentinel lymph-node biopsy and FDG-PET in staging and radiation treatment of anal cancer patients.

To assess the role of sentinel lymph-node biopsy (SLNB) and FDG-PET in staging and radiation treatment (RT) of anal cancer patients. This retrospective study was performed on 80 patients (male: 32, female: 48) with a median age of 60 years (39-89 years) with anal squamous cell carcinoma who were treated from March 2008 to March 2018 at the IRCCS San Raffaele Hospital. Patients without clinical evidence of inguinal LNs metastases and/or with discordance between clinical evidence and imaging features were considered for SLNB. FDG-PET was performed in 69/80 patients. Patients with negative imaging in inguinal region and negative SLNB could avoid RT on groin to spare inguinal toxicity. CTV included GTV (primary tumour and positive LNs) and pelvic ± inguinal LNs. PTV1 and PTV2 corresponded to GTV and CTV, respectively, adding 0.5 cm. RT dose was 50.4 Gy/28 fractions to PTV2 and 64.8 Gy/36 fractions to PTV1, delivered with 3DCRT (n = 24) or IMRT (n = 56), concomitant to Mitomycin-C and 5-FU chemotherapy. FDG-PET showed inguinal uptake in 21/69 patients (30%) and was negative in 48/69 patients (70%). Lymphoscintigraphy was performed in 11/21 positive patients (4 patients SLNB confirmed inguinal metastases, 6 patients false positive and 1 patient SLN not found), and in 29/48 negative patients (5/29 showed metastases, 23/29 true negative and 1 SLN not found). Sensitivity, specificity, positive and negative predictive value of FDG-PET were 62%, 79%, 40% and 82%, respectively. Median follow-up time from diagnosis was 40.3 months (range: 4.6-136.4 months): 69 patients (86%) showed a complete response, 10 patients (13%) a partial response, 1 patient (1%) a stable disease. Patients treated on groin (n = 54) versus not treated (n = 26) showed more inguinal dermatitis (G1-G2: 50% vs. 12%; G3-G4: 17% vs. 0%, p < 0.05). For patients treated on groin, G3-G4 inguinal dermatitis, stomatitis and neutropenia were significantly reduced with IMRT against 3DCRT techniques (13% vs. 36%, p = 0.10; 3% vs. 36%, p = 0.003; 8% vs. 29%, p = 0.02, respectively). SLNB improves the FDG-PET inguinal LNs staging in guiding the decision to treat inguinal nodes. IMRT technique significantly reduced G3-G4 toxicities when patients are treated on groin.

Presence of multiple genotypes in subjects with HPV-16 infection is highly associated with anal squamous intraepithelial lesions in HIV-1 infected males.

OBJECTIVES: The aim of the study was to determine the prevalence of abnormal cytological findings, high risk (HR)-HPV genotypes and to identify factors associated with an abnormal cytological findings in a cohort of HIV-infected males. PATIENTS AND METHODS: Retrospective observational study on HIV-infected male patients who performed screening in the absence of clinical symptoms. Cytological abnormalities were classified as atypical squamous cells of undetermined significance (ASC-US), low-grade(LSIL) or high high-grade squamous intraepithelial lesion (HSIL). Logistic regression models were used to identify predictors of having LSIL/HSIL. RESULTS: Among 875 pts, abnormal cytology findings were observed in 254 (29%, 95% CI: 26.1%-32.1%) subjects: 142 (16%) had LSIL and 49 (6%) HSIL. Overall, 581 (66%, 95%CI: 63.2%-69.5%) subjects had ≥1 HR-HPV type and 269 (31%) had ≥2 HR HPV types. Multivariate logistic regression showed that subjects with multiple HR-HPV genotypes (OR = 1.351, 95%CI: 1.005-2.111) and with HPV-16 type (OR = 2.032, 95%CI: 1.313-3.146) were more likely to have LSIL/HSIL in addition to a lower CD4+/CD8+ ratio, a previous diagnosis of syphilis and a positive viral load. In another multivariate model, the presence of multiple HPV types in subjects with HPV-16 type was associated with the highest adjusted OR of having a LSIL/HSIL (OR = 2.598, 95%CI: 1.460-4.624). CONCLUSIONS: In HIV-infected men, the prevalence of abnormal cytological findings was of 29% and of HR-HPV was 66%. The concomitant presence of HPV-16 and multiple HR genotypes was associated with an increased risk of abnormal cytological findings. These data highlight the importance of screening multiple HPV genotypes in HIV-infected patients.

Feasibility of an adaptive strategy in preoperative radiochemotherapy for rectal cancer with image-guided tomotherapy: boosting the dose to the shrinking tumor.

PURPOSE: To investigate the feasibility of preoperative adaptive radiochemotherapy by delivering a concomitant boost to the residual tumor during the last 6 fractions of treatment. METHODS AND MATERIALS: Twenty-five patients with T3/T4N0 or N+ rectal cancer were enrolled. Concomitant chemotherapy consisted of oxaliplatin 100 mg/m(2) on days -14, 0, and +14, and 5-fluorouracil 200 mg/m(2)/d from day -14 to the end of radiation therapy (day 0 is the start of radiation therapy). Radiation therapy consisted of 41.4 Gy in 18 fractions (2.3 Gy per fraction) with Tomotherapy to the tumor and regional lymph nodes (planning target volume, PTV) defined on simulation CT and MRI. After 9 fractions simulation CT and MRI were repeated for the planning of the adaptive phase: PTVadapt was generated by adding a 5-mm margin to the residual tumor. In the last 6 fractions a boost of 3.0 Gy per fraction (in total 45.6 Gy in 18 fractions) was delivered to PTVadapt while concomitantly delivering 2.3 Gy per fraction to PTV outside PTVadapt. RESULTS: Three patients experienced grade 3 gastrointestinal toxicity; 2 of 3 showed toxicity before the adaptive phase. Full dose of radiation therapy, oxaliplatin, and 5-fluorouracil was delivered in 96%, 96%, and 88% of patients, respectively. Two patients with clinical complete response (cCR) refused surgery and were still cCR at 17 and 29 months. For the remaining 23 resected patients, 15 of 23 (65%) showed tumor regression grade 3 response, and 7 of 23 (30%) had pathologic complete response; 8 (35%) and 12 (52%) tumor regression grade 3 patients had ≤5% and 10% residual viable cells, respectively. CONCLUSIONS: An adaptive boost strategy is feasible, with an acceptable grade 3 gastrointestinal toxicity rate and a very encouraging tumor response rate. The results suggest that there should still be room for further dose escalation of the residual tumor with the aim of increasing pathologic complete response and/or cCR rates.

Laparoscopy-assisted gastrectomy versus open gastrectomy for gastric cancer: a monoinstitutional Western center experience.

BACKGROUND: Laparoscopic gastrectomy (LAG) is safe for benign lesions; however, such surgery for cancer remains controversial. The aim of this study was to compare technical feasibility and oncologic efficacy of laparoscopic versus open gastrectomy for gastric carcinoma. METHODS: Between January 2002 and November 2008, 109 gastric cancer patients underwent LAG (92 distal gastrectomy and 17 total gastrectomy) at our hospital. These patients were compared with 269 gastric cancer patients who underwent conventional open gastrectomy (OG; 171 distal gastrectomy and 98 total gastrectomy) during the same period. RESULTS: Operation time was significantly longer in the LAG group than in the OG group. Estimated blood loss in the LAG group was significantly less than in the OG group. The morbidity rate was higher than in the OG group (p < 0.0001). The distance of the proximal resection margin was significantly lower in the OG group (2.8 ± 1.9 vs. 3.8 ± 2.5; p = 0.014). The mean number of nodes resected with LAG was 31 ± 14 and that with OG was 27 ± 13 (p = 0.002). The mean survival time was 53 months in both groups. There were no differences regarding overall patient survival at a mean time of follow-up of 33 months. CONCLUSIONS: LAG with extended lymphadenectomy for gastric cancer is a feasible and safe procedure and has several advantages despite a higher rate of morbidity. Moreover, this method can achieve a radical oncologic equivalent resection and it does not have a deleterious effect on cancer-related outcome.

Experience on surgical treatment of gastrointestinal stromal tumor of the stomach.

In spite of their rarity, gastrointestinal stromal tumors (GISTs) represent a complex clinical problem, mainly diagnostic and therapeutic, for their unpredictable biological course and their long-term prognosis, the most involved site being the stomach. Although a great number of tyrosine-kinase inhibitors has been developed for blocking their proliferative pathways (constitutive CD117 and PDGFRa activation), surgical treatment still remains the only curative one. Nevertheless, their particular non-lymphatic spread and their tendency to peritoneal seeding have emphasized technical issues that are still greatly debated. The definition of the best surgical procedure aiming at the complete R0 resection of the tumor has changed in the recent years and, with the improvement of laparoscopic techniques, the minimally invasive approach of gastric GIST has become feasible in most cases. In this paper we present our experience on surgical treatment of 43 gastric GISTs observed from 2001 to 2008 taken from our case study (75 patients from 1994). The risk class, treatment and long-term follow-up (mean 36 months) has been analyzed. All patients underwent a surgical procedure; 10 of them were also treated with molecular tyrosine-kinase inhibitors as adjuvant treatment. Overall survival at 60 months was 89.3%, with a disease-free survival of 87.68%.

Total mesorectal excision (TME) with laparoscopic approach: 226 consecutive cases.

BACKGROUND: Total mesorectal excision (TME) of the rectum has been advocated as the gold surgical treatment of the middle and low third rectal cancer. Laparoscopy has gained acceptance among surgeons in the treatment of colon malignancies, while scepticism exists about laparoscopic TME in term of safety, and its oncological adequacy. OBJECTIVE: To evaluate the impact of laparoscopic TME on surgical and oncological outcome in a group of consecutive unselected patients. METHODS: 226 unselected patients with rectal cancer underwent laparoscopic TME from January 1998 to August 2007. Patients staged cT3/4 cTxN+ were submitted to neoadjuvant treatment. Postoperative complications and oncological outcome were registered. RESULTS: Mean distance of the tumour from the anal verge was 6.2+/-2 cm. 48.6% of patients were enrolled in "long-course" neoadjuvant chemo-radiotherapy (partial and complete response rates 72.4% and 20.1%, respectively). Surgical procedures were 202 anterior and 24 abdominal-perineal resections. Mean operative time 245.3+/-58.4 min, mean blood loss 203+/-176 mL. Conversion rate 6.1%. Thirty-days morbidity rate 31.8% without mortality. Anastomotic leaks rate was 16.8%. Reoperation rate 6.6%. Gastrointestinal recovery rate was 3.1+/-1.4 days and hospital stay 10.4+/-4.6 days. Concerning adequacy of oncologic resection, mean distance between tumour and margin of resection was 2.7+/-2 cm with a nodal sampling of 14.4+/-4.6. Six patients (2.6%) had a R1 margin. With a mean follow-up of 39.8 months non port-site metastases occurred. Local recurrence rate was 6.1%. Five years cumulative overall survival was 81% and disease-free survival was 70% (Kaplan-Meier method). CONCLUSIONS: Laparoscopic approach for rectal tumour is a technically demanding procedure, but it is safe and it has the feature of an oncologic procedure.

Impact of age on postoperative outcomes in 1118 gastric cancer patients undergoing surgical treatment.

BACKGROUND: The purpose of the study was to evaluate the impact of age on outcomes in gastric cancer surgery. METHODS: Patients on the hospital database who underwent gastric resection for gastric cancer during the period 1990-2005 (n = 1118) were divided into two groups: group A, patients 75 years or older (n = 249), and group B, those younger than 75 years (n = 869). RESULTS: Overall preoperative complications were diagnosed in 92 (37%) patients of group A, compared with 147 (17%) in group B (P = 0.002). Fifty-five percent of patients underwent resection with D2 or more lymph node dissection (37% [n = 93] in group A, and 60% [n = 521] in group B; P = 0.003). Postoperative overall morbidity was higher in the elderly group (29% in group A versus 23% in group B), but the difference between the two groups was not significant (P = NS). Overall postoperative surgical complications were recorded in 201 (18%) patients; 49 (20%) in the elderly cohort, compared with 147 (17%) in the younger group (P = NS). The postoperative mortality rate was 3% (n = 7) in the elderly group, compared with 3% (n = 26) in the younger cohort (P = NS). Multivariate Cox analysis showed that age was not an independent risk factor for postoperative morbidity and mortality. Overall 5-year survival was 47% in group A and 54% in group B (P = NS). CONCLUSION: Due to improved perioperative management, resection of gastric carcinoma is the treatment of choice in elderly patients. Although comorbidities were more frequent among the elderly patients, postoperative morbidity and mortality, even after extensive resections, was low. Survival rates were comparable to those in the younger patients.

[The role of neoadjuvant radio-chemotherapy in the treatment of rectal cancer]. / Il ruolo della radiochemioterapia neoadiuvante nel trattamento del tumore del retto.

OBJECTIVE: To evaluate oncological and surgical outcome of patients submitted to neoadjuvant therapy for advanced rectal cancer. PATIENTS AND METHOD: One hundred thirty eight patients (86 male, 52 female, mean age 61.4 years), with tumour of lower (58; 42%), middle (66; 48%), upper rectum (14; 10%), showing a clinical stage II (23; 17%) or III (115; 83%) and with an average distance from anal verge of 6.5 cm, submitted to fractionated "long-course" RT with CT locally staged by US and MR before and after neoadjuvant therapy and operated on after 4-6 weeks by its end. RESULTS: Surgical procedures (71 of which laparoscopic) were: 114 AR (83.8%), 19 APR (14%) and 3 TEM (2.2%). Mean nodal-sampling was 14.9. A complete or partial response was observed in 48.5% of the patients (67/138). With a mean follow-up of 30 months, local recurrence rate was 5.7%. Five-years overall survival and disease-fee-survival were respectively 73% and 60%. DISCUSSION: We observed a significant clinical (p < 0.004) and pathological (p < 0.005) downstaging. Pre-treatment clinical stage was not significant. On the contrary, postoperative yTNM was significant for yT (p < 0.001) and yN (p < 0.0003). Non-responder patients had worse prognosis (5-years survival 30%). The variable with higher prognostic significance was yN (p < 0.0003), especially if we distinguish N1 by N2 (p < 0.0004). CONCLUSIONS: The response to neoadjuvant therapy represents a significant prognostic variable.

Laparoscopic vs. open colectomies in octogenarians: a case-matched control study.

PURPOSE: The aim of this study was to define any benefits in terms of early outcome for laparoscopic colectomy in patients over 80 years old compared with open colectomy. METHODS: Sixty-one patients undergoing laparoscopic colectomy for colorectal cancer were matched to 61 open colectomy patients for gender, age, year of surgery, site of cancer, and comorbidity on admission. Independence status on admission and at discharge from the hospital was also evaluated. RESULTS: Mean (standard deviation) age was 82.3 (3.5) years in the laparoscopy group and 83.1 (3.3) years in the open group. Conversion rate was 6.1 percent. Operative time was 49 minutes longer in the laparoscopy group (P = 0.001). The overall mortality rate was 2.4 percent. The morbidity rate was 21.5 percent in the laparoscopy group and 31.1 percent in the open group (P = 0.30). Patients in the laparoscopy group had a faster recovery of bowel function (P = 0.01) and a significant reduction of the mean length of hospital stay (9.8 vs. 12.9 days for the open group, P = 0.001). Laparoscopy allowed a better preservation of postoperative independence status compared with the that of the open group (P = 0.02). CONCLUSION: Laparoscopic colectomy for cancer in octogenarians is safe and beneficial including preservation of postoperative independence and a reduction of length of hospital stay.

[Laparoscopic pancreatic resection: preliminary experience]. / Chirurgia laparoscopica del pancreas: esperienza preliminare.

The aim of the study was to evaluate the results of laparoscopic pancreatectomy for pancreatic tumours. Four women and three men underwent laparoscopic pancreatectomy and were recruited into the study retrospectively over the period from June 2002 to February 2004. Pancreaticoduodenectomy (n = 4), intermediate pancreatectomy (n = 1) and distal pancreatic resection with splenectomy (n = 2) were successfully performed. Operative mortality was nil. The postoperative morbidity included two low-output pancreatic leaks. Mean operating time, blood loss and hospital stay were 342 minutes, 289 mL and 14 days, respectively. The pathological diagnosis was ductal adenocarcinoma in one, neuroendocrine tumour in five and metastatic melanoma in one. All patients are still well after a median follow-up of 7 months (range: 1-20 months). The patients appear to benefit from laparoscopic pancreatectomy for pancreatic tumours. The minimally invasive approach ensures adequate treatment but requires the expertise of highly skilled laparoscopic surgeons.
