Hospital admissions from alcohol-related acute pancreatitis during the COVID-19 pandemic: A single-centre study.

BACKGROUND: The United Kingdom government introduced lockdown restrictions for the first time on 23 March 2020 due to coronavirus disease 2019 (COVID-19) pandemic. These were partially lifted on 15 June and further eased on 4 July. Changes in social behaviour, including increased alcohol consumption were described at the time. However, there were no data available to consider the impact of these changes on the number of alcohol-related disease admissions, specifically alcohol-related acute pancreatitis (AP). This study evaluated the trend of alcohol-related AP admissions at a single centre during the initial COVID-19 lockdown. AIM: To evaluate the trend in alcohol-related AP admissions at a single centre during the initial COVID-19 lockdown in the United Kingdom. METHODS: All patients admitted with alcohol-related AP from March to September 2016 to 2020 were considered in this study. Patient demographics, their initial presentation with AP, any recurrent admissions, disease severity and length of stay, were evaluated using ANOVA and χ 2 and Kruskal-Wallis tests. RESULTS: One hundred and thirty-six patients were included in the study. The highest total number of AP admissions was seen in March-September 2019 and the highest single-month period was in March-May 2020. Admissions for first-time presentations of AP were highest in 2020 compared to other year groups and were significantly higher compared to previous years, for example, 2016 (P < 0.05). Furthermore, the rate of admissions decreased by 38.89% between March-May 2020 and June-September 2020 (P < 0.05), coinciding with the easing of lockdown restrictions. This significant decrease was not observed in the previous year groups during those same time periods. Admissions for recurrent AP were highest in 2019. The median length of hospital stay did not differ between patients from each of the year groups. CONCLUSION: An increased number of admissions for alcohol-related AP were observed during months when lockdown restrictions were enforced; a fall in figures was noted when restrictions were eased.

Elective splenectomy in patients with non-Hodgkin lymphoma: Does the size of the spleen affect surgical outcomes?

Backgrounds/Aims: Splenectomy in patients with non-Hodgkin lymphoma (NHL) is performed to relieve abdominal symptoms, treat hypersplenism or confirm diagnosis. Excision of a very large spleen is technically challenging and data on outcomes of surgery in patients with NHL are scanty. The aim of study was to evaluate the impact of spleen size on the surgical outcome of splenectomy in patients with NHL. Methods: Patients with NHL who underwent splenectomy, between 2006 and 2017, were included and divided into two groups: group 1, spleen ≤ 20 cm; group 2, spleen > 20 cm. Surgical approach, operative time, postoperative morbidity, mortality, hospital stay and re-admission rates were retrospectively compared between groups. Non-parametric data were evaluated with the Mann-Whitney U test. Differences in frequencies were analyzed with Fisher's exact test. Results: Sixteen patients were included (group 1, 6; group 2, 10). Laparoscopy was successful in three patients of group 1, none of group 2 (p = 0.035), the intraoperative time did not differ significantly between groups. One patient in each group developed postoperative complications. The patient in group 1 died of pneumonia. Median length of stay was 8 days (range, 3-16 days) for group 1, 5.5 days (range, 3-10 days) for group 2, showing no significant difference between the two groups. No patient was readmitted to hospital. Conclusions: Spleen size does not affect the outcome of splenectomy in patients with NHL. If a mini-invasive approach is to be chosen, laparoscopy may not be feasible when the spleen size is > 20 cm.

Can Preoperative Characteristics Predict the Outcomes of Laparoscopic Cholecystectomy?

Background: Intraoperative findings during laparoscopic cholecystectomy (LC) are highly unpredictable and operative difficulty varies from straightforward to very challenging procedures. Several studies described predictors of technical difficulty and graded intraoperative findings of LC; however, none specifically reported on the effect of such factors on clinical outcomes. This study aims to evaluate if preoperative characteristics of patients undergoing LC predict how likely they are to fail to be day case (DC). Methods: Data of patients who underwent LC from 2015 to 2017 were retrospectively analyzed. Subjects were divided into four groups, according to Nassar's classification of intraoperative difficulty. Differences in frequencies were evaluated with the the chi square and post hoc chi square tests or Fisher's exact test; logistic regression analysis was used to identify independent variables that were predictors of intraoperative complexity, postoperative morbidity, and length of stay. Results: A total of 1043 patient were included with male to female ratio of 1:2.5. Older age, male gender, and comorbidities were associated with higher Nassar score (P < .0001); Nassar 3 and 4 were predictors of postoperative morbidity (P < .05). The DC rate was 74.2% (Nassar 1), 75.8% (Nassar 2), 61.1% (Nassar 3), and 26.2% (Nassar 4), respectively. Age ≥60 years (P < .05), body mass index ≥35 (P < .05), and Nassar 3 and 4 (P < .05) were predictors of increased conversion from DC to inpatient (IP) stay. Conclusion: LC can be safely performed on a DC basis even when surgery is technically challenging. The need of IP stay can be predicted in comorbid old adult men with anticipated higher Nassar's score.

Oncological and functional outcomes of testis sparing surgery in small testicular mass: a systematic review.

INTRODUCTION: The prevalence of testicular tumor is constantly increasing, with an estimated incidence rate of about 3-10 new cases per 100,000 males/per year. Radical orchiectomy or testis sparing surgery (TSS) are recognized therapeutic approaches in these cases. However, the risk for hypogonadism and infertility is higher with the former compared with the latter. The aim of this systematic review is to evaluate the oncological outcome and testicular function (endocrine and reproductive aspects) in patients who had undergone TSS for small testicular lesions. EVIDENCE ACQUISITION: To accomplish this, 684 articles were retrieved and screened; 24 retrospective and two prospective studies were selected and finally included in this systematic review. EVIDENCE SYNTHESIS: Overall the TSS attempts were 1096 but TSS was definitively performed in 603 cases (55%). Frozen section examination was performed in 996 TSS attempts (22 out of the 26 studies selected) and showed a benign histology in 37-100% of cases, a malignant histology in 0-63%, and an inconclusive result in 0-16%, respectively. Five studies reported that a total of 22 patients were able to father after conservative surgery. None of these studies reported cases of hypotestosteronemia after surgery and a low prevalence (1.66%) of complications was associated with this type of surgery. CONCLUSIONS: In conclusion, TSS showed to be safe and practicable if used according to the specific guidelines. It can be safely performed to treat recurrence eventually associated to local adjuvant radiotherapy when an intra-tubular neoplasia is present. Urologists can therefore consider TSS as an important means against testicular tumor in selected and well-informed patients.

Laparoscopic partial splenectomy using the harmonic scalpel for parenchymal transection: two case reports and review of the literature.

Laparoscopic splenectomy is nowadays widely performed for the treatment of benign and malignant diseases of the spleen. However, removing the spleen increases the risk of postoperative infections, therefore patients need long-life antibiotics. Advancement in surgical technique and instrumentation have led to the development of partial splenectomy, which is mainly indicated to treat localized lesions of the spleen. The main advantage is the preservation of the immune function, so that long-life prescription of antibiotics is no longer needed. The introduction of the laparoscopic approach to laparoscopic splenectomy seems to add further benefits, namely a faster recovery. We report two cases of benign splenic cysts, which were treated by laparoscopic partial splenectomy. Technical aspects on the parenchymal transection and data from the most recent literature are discussed as well.

Does the Implementation of a Clinical Care Pathway Have an Impact on Early Intravenous Fluid Therapy of Acute Pancreatitis?: A Pilot Quality Improvement Study.

OBJECTIVES: Early intravenous fluid (IVF) resuscitation is crucial in the management of acute pancreatitis; variation in IVF prescription practice had been demonstrated. This pilot study aims to assess whether the implementation of an Acute Pancreatitis Care Pathway (APCP) produces a change toward a more adequate IVF regimen in the first 24 hours. METHODS: Patients with confirmed diagnosis of acute pancreatitis, from July 2015 to February 2016 (group 1) and from September 2017 to March 2018 (group 2), were considered. The APCP was developed between March 2016 and August 2017. Median IVF rate, volume, and type infused in the first 24 hours, were compared between groups. Nonparametric data were analyzed with the Mann-Whitney U test, differences in frequencies with the McNemar test; significance was set at P < 0.05. RESULTS: Seventy-two patients were included, 36 in each group. In the first 24 hours, the median IVF rate was 177 mL/h vs 225 mL/h (P = 0.004); Ringer lactate infusion was 30% vs 77.8% (P = 0.0003). The median total IVF volume did not differ between groups. CONCLUSIONS: The implementation of the APCP has the potential to lead to a successful change in early IVF resuscitation practice.

Routine examination of gallbladder specimens after cholecystectomy: a single-centre analysis of the incidence, clinical and histopathological aspects of incidental gallbladder carcinoma.

BACKGROUND: Gallbladder carcinoma is often found incidentally on histopathologic examination after cholecystectomy-this is referred as incidental gallbladder carcinoma (IGC). Routine vs selective histopathological assessment of gallbladders is under debate and this study evaluates the role of regular specimens' examination, based on a single-centre analysis of incidence, clinical and histopathological aspects of IGC. METHODS: Patients who underwent cholecystectomy, between July 2010 and January 2020, were considered. Exclusion criteria were age under 18 and preoperative diagnosis of GB carcinoma. Demographic, clinical and histopathological data were retrospectively collected, continuous variables with a normal distribution were evaluated with Student's t-test and ANOVA. RESULTS: Some 5779 patients were included. The female/male ratio was 2.5:1. Chronic cholecystitis (CC) was the most common finding on specimens (99.3%), IGC was found in six cases (0.1%). In the latter group, there were 5 women and patients were older than those with benign disease-73.7 [Formula: see text] 5.38 years vs 55.8 [Formula: see text] 0.79 years (p < 0.05). In all the cases, the GB was abnormal on intraoperative inspection and beside cancer, histopathology showed associated CC and/or dysplasia. Upon diagnosis, disease was at advanced stage-one stage II, one stage IIIA, one stage IIIB, three stage IVA. Two patients are alive, three died of disease progression-median survival was 7 months (range 2-14). CONCLUSIONS: In this series, ICG was rare, occurred most commonly in old adult women and was diagnosed at an advanced stage. In all the cases, the GB was abnormal intraoperatively, therefore macroscopic GB anomalies demand histopathological assessment of the specimen.

Complications of endourological procedures and their treatment.

Endourological treatment for urinary stones and other obstructive urinary tract diseases is minimally invasive but in some cases it involves serious complications. This collection of cases describes some complications of endourological procedures and how they were treated. Case 1: A case of right ultrasound-guided percutaneous nephrostomy found to be misplaced in the inferior vena cava. The case was safely managed, but it showed that ultrasound guidance alone may be insufficient so it is recommended that percutaneous nephrostomy should be always placed under fluoroscopic control, either alone or in combination with ultrasound guidance. Case 2: A case of renal subcapsular hematoma occurring on retrograde intrarenal surgery at high perfusion pressure. The hematoma was drained under combined ultrasonic and radiological guidance. Post treatment recovery was uneventful. Large stone size, severe ipsilateral hydronephrosis, long operation time, higher hydrostatic pressure of the irrigating solution and low ureteral wall compliance are supposed to be risks factors associated with renal subcapsular formation. Management strategy should be tailored to patient's clinical conditions. In hemodynamically stable patients, large hematoma drainage is recommended to prevent further complications and favours early recovery. Case 3: A case of double J stent fracture discovered one month after the insertion to relieve obstruction from a 1 cm stone in the right proximal ureter. The distal fragment of the stent was removed by cystoscopy while the proximal fragment was removed by semirigid ureteroscopy in two sessions due to fever and extensive calcification. Case 4: A mini-invasive technique for transurethral replacement of completely encrusted urinary stents in female patients. This technique allows the interventional radiologist to replace obstructed urinary stents by avoiding more invasive and traumatic urological procedures with sedation.

Outcome of acute pancreatitis in octogenarians: A retrospective study.

BACKGROUND AND AIM: Acute pancreatitis (AP) is a common disease, but data on outcomes in octogenarians are scarce in the literature. The aim of this study is to analyze results from patients aged 80 years old and over who were treated for AP at a single center. METHODS: Patients aged 80 years and older diagnosed with AP from April 2010 to October 2015 were considered. Demographics, American Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), serum biochemistry at 24 and 48 h after admission, and revised Atlanta severity score were analyzed and correlated with hospital mortality rate and length of stay using the multiple regression and Kaplan-Meier tests. RESULTS: A total of 100 consecutive patients were included in the study. There were 52 women, and the mean age was 87.5 years (range 80-95). Gallstones were the most common cause of AP (69.7%). The ASA score was ≥III in 51 patients. Eight patients had severe, disease and all of them died in hospital. A CCI > 4 was associated with higher disease severity and mortality (P < 0.00001). The median hospital stay was 9 days (range 1-59). Longer hospital stay was associated with serum C-reactive protein ≥242 mg/L (P = 0.01) and serum albumin ≤30 g/L (P = 0.01) at 48 h. Over a 5-year period, 22% of patients were readmitted to hospital with recurrent AP. Gallstones were the main cause of disease (63.6%). CONCLUSIONS: AP in octogenarians has low mortality. Higher death rate is associated with disease severity. In the presence of gallstone disease, cholecystectomy is recommended whenever possible as the risk of disease recurrence is significant.

Clinical and psychological outcomes of patients undergoing Retrograde Intrarenal Surgery and Miniaturised Percutaneous Nephrolithotomy for kidney stones. A preliminary study.

PURPOSE: To assess disease-specific and health-related QoL, anxiety and depression as well as satisfaction regarding retrograde intrarenal surgery (RIRS) and miniaturized percutaneous nephrolithotomy (mPCNL) intervention for kidney stones up to 2.5 cm. Secondarily, pain as well as perioperative and postoperative patient outcomes were evaluated. METHODS: 60 consecutive patients with kidney stones of dimensions not exceeding 2.5 cm were enrolled in the study of which 30 underwent RIRS and 30 mPCNL. Perioperative characteristics (age, gender, body mass index (BMI), stone side and size, previous interventions for kidney stones and duration of hospitalization) and surgical outcomes (hemoglobin drop, stone-free rate, visual analogue scale (VAS), stenting time, size of ureteral access sheath (UAS) deployment, and postoperative complications) of patients were collected. Quality of life and psychological outcomes were evaluated using validated questionnaires. RESULTS: No significant differences were found between the two groups in terms of age, gender, BMI, stone side and size (p > 0.05). Significant differences between the mPCNL and the RIRS groups were found regarding stenting time (p = 0.032) and duration of hospital stay (p < 0.001). The stone-free rates of mPCNL vs RIRS were not significantly different between the two groups (73.3% vs 66.7%, p > 0.05). Peri- and postoperative complications were not statistically different between the two groups (p > 0.05). RIRS group reported higher anxiety and depression scores compared with the mPCNL group (3 [range 0-15] vs 15 [range 6-24], p < 0.01). We found significant differences between the two groups in social (p < 0.05) and vitality (p < 0.01) scores. VAS pain score was significantly lower in the mPCNL group than in the RIRS one (p < 0.05). CONCLUSIONS: These results open new scenarios in the treatment of kidney stones up to 2.5 cm when RIRS and mPCNL have interchangeable indications. Since in our experience complications and success rate are similar, the surgical choice of switching from RIRS to mPCNL in real-time and viceversa may be proposed to the patient in the preoperative counseling.

Outcome of Laparoscopic Common Bile Duct Exploration After Failed Endoscopic Retrograde Cholangiopancreatography: A Comparative Study.

Background: Common bile duct stones (CBDS) are treated with endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC) or with the single-stage laparoscopic common bile duct exploration (LCBDE) and LC. Multiple ERCP attempts and failure increase the risk of postprocedural complications. In such circumstances surgery is advocated. The aim of the study is to compare the outcome of LCBDE and LC in patients who had never had an ERCP, to that of patients who underwent previously failed ERCP. Methods: A retrospective analysis of 54 patients undergoing LCBDE and LC between 2010 and 2017, was performed. Patients were divided in 2 groups: primary surgery (group 1), surgery after failed ERCP (group 2). Demographics and preoperative investigation results were collected. Comparative outcomes were common bile duct (CBD) clearance rate, operative time, conversion to open rate, postoperative morbidity, mortality, and hospital stay. Data were evaluated with the Student's t, Chi-square, or Fisher's tests. Results were considered as statistically significant when P < .05. Results: In both groups CBD clearance was above 90%. The mean operative time was longer in group 2 (130.3 minutes ± SD 83.72 vs. 178.73 ± 57.22; P < .05). There was no difference in the conversion to open and postoperative complication rates between groups. A bile leak occurred in 2 patients from group 1, 3, from group 2. No postoperative mortality occurred. The median hospital stay was longer in group 2 (2 days ± SD 2.54 vs. 5 ± 5.77; P < .05). Conclusions: LCBDE and LC is safe and effective in patients who had previous failed ERCP. If ERCP failure is anticipated and/or the risk of post-ERCP complications is high, surgery should be considered as the first-line treatment of CBDS. Longer intraoperative time and hospital stay are expected.

An Unusual Case of Primary Extranodal Lymphoma of the Gallbladder.

Primary gallbladder lymphoma is an extremely rare disease. We report a case of a 63 year-old woman who has been admitted with gradual onset abdominal pain in the upper right quadrant and in the suprapubic region, nausea and malaise. According to the computed tomography scan of the abdomen, which was suggestive of chronic cholecystitis, she was treated conservatively. A laparoscopic cholecystectomy was performed 5 months later and the histological examination of the gallbladder showed a low grade small lymphocytic lymphoma. The patient has been taken over by the hematology team who kept her under surveillance as no further treatment was deemed as necessary. The purpose of this paper is to report a rare case of primary gallbladder lymphoma and to demonstrate that a laparoscopic cholecystectomy may be a valid treatment for this disease.

Rendezvous technique for cholecystocholedochal lithiasis in octogenarians: is it as effective as in younger patients, or should endoscopic sphincterotomy followed by laparoscopic cholecystectomy be preferred?

BACKGROUND: The treatment of cholecystocholedochal lithiasis (CCL) requires cholecystectomy and common bile duct (CBD) clearance, which can be achieved surgically or with a combination of surgery and endoscopy. The latter includes a two-stage-approach-preoperative retrograde cholangiography (ERC) and sphincterotomy (ST) followed by delayed laparoscopic cholecystectomy (LC), or vice versa-or a one-stage-approach-the rendezvous technique (RVT), where ERC, ST, and LC are performed during the same procedure. No data on the use of RVT in octogenarians have been reported in the literature so far. The study aims to show whether the RVT is as effective in elderly as in younger patients. Moreover, results of RVT are compared with those of a two-stage sequential treatment (TSST) in octogenarians, to identify the best approach to such a population. SUBJECTS AND METHODS: Prospectively collected data of 131 consecutive patients undergoing RVT for biliary tract stone disease were retrospectively analyzed. Two analyses were performed: (1) results of RVT (operative time, conversion rate, CBD clearance, morbidity/mortality, hospital stay, costs, and need for further endoscopy) were compared between octogenarians and younger patients, and (2) results of RVT in the elderly were compared with those of 27 octogenarians undergoing TSST for CCL. RESULTS: Octogenarians undergoing RVT were in poorer general condition (P<.0001) and had a higher conversion rate (P<.0001) and a longer hospital stay (P<.007) than younger patients. No differences in the rates of CBD clearance, surgery-related morbidity, mortality, and costs were recorded. Although octogenarians undergoing RVT were in poorer general condition than those undergoing TSST, the results of the two approaches were similar. CONCLUSIONS: RVT in the elderly seems to be as cost-effective as in younger patients; nevertheless, it may lead to a higher conversion rate and longer hospital stay. In octogenarians, RVT is not inferior to TSST in the treatment of CCL even for patients in poor condition.

Multidetector computed tomography aspects of tracheal mucosal leishmaniasis localization.

Tracheal mucosal localization of Leishmania is considered a rare and dangerous event. A single case of leishmaniasis of the trachea has been described in literature. Our work describes multidetector computed tomography features of leishmaniasis localized in the tracheal mucosa that occurred in a 68-year-old patient who lived in an endemic zone. Our patient underwent biopsy that established the diagnosis of leishmaniasis.

Elective palliative resection of incurable stage IV colorectal cancer: who really benefits from it?

PURPOSE: Despite the encouraging results of chemotherapy in patients affected by incurable colorectal cancer (CRC), surgical resection of a primitive tumor is still a common approach worldwide. The identification of prognostic factors related to short survival (<6 months) may allow excluding from resective surgery those who may not benefit from it. METHODS: A retrospective analysis was performed of 15 variables in a population of 71 patients undergoing nonemergency palliative primary resections of incurable CRC, including patients' demographics and clinical/histopathological characteristics of the tumor. RESULTS: No variables were related to perioperative mortality (8.5% overall). A multivariate analysis revealed that older age (≥80 years) and metastasis to more than 25% of the lymph nodes were associated with survival (4 and 6 months, respectively). Mucoid adenocarcinoma therefore tends to be associated with the prognosis (P = 0.070). CONCLUSIONS: An elderly age tends to be a contraindication to an elective primary tumor resection in patients affected by incurable CRC. Massive lymph node involvement and mucoid adenocarcinoma should also be considered before planning major colonic surgery.

Impact of palliative chemotherapy and surgery on management of stage IV incurable colorectal cancer.

BACKGROUND: Recent trials proposed chemotherapy (CHT) as the treatment of choice for patients affected by incurable colorectal cancer (ICRC). Nevertheless, surgery is still commonly offered to these patients. On the other hand, CHT is offered to ICRC patients regardless of the pattern of spread of the disease, local or distant, despite some evidence suggesting that metastatic pattern may influence the response to treatment. METHODS: A retrospective analysis was performed of 133 patients undergoing palliative treatment for ICRC from 1994 through 2007. Palliation consisted of surgery alone until 2002 and surgery with CHT (FOLFOX-FOLFIRI) thereafter. The impact of CHT and surgery was evaluated in the whole series as well as with respect to metastatic pattern (locally aggressive primary tumor and distant metastasis only), tumor site, and grading. RESULTS: Chemotherapy prolonged survival by 9 months (p = 0.001). In patients undergoing CHT, resective surgery did not prolong survival (p = 0.931), whereas in patients not undergoing CHT, it improved prognosis by 5 months (p = 0.023). Considering patients with distant metastasis only, CHT significantly prolonged survival (p < 0.001), whereas it did not improve the prognosis of patients with a locally aggressive primary tumor (p = 0.943). No difference in CHT effectiveness with respect to tumor site and grading was recorded. CONCLUSIONS: CHT should be the preferred option in patients undergoing elective treatment for ICRC, whereas surgery should be considered whenever CHT is not administered. CHT significantly increases survival of patients with unresectable distant metastasis only, whereas it seems to be useless in patients with locally aggressive primary tumors.

An exceptional postoperative gastric tube bleeding after esophageal resection for cancer.

A case of gastric tube bleeding after an Ivor-Lewis esophagectomy with gastroesophageal anastomosis is reported. During the early postoperative course, the patient had a gastric tube stasis that improved progressively. The subsequent onset of a serious and intermittent hematemesis, which was endoscopically deemed to be the result of a hemorrhagic gastritis, required multiple blood transfusions. The evolution to a severe hemodynamic instability obliged us to reoperate on the patient. During surgery, a band-related obstruction of the first jejunal loop with local signs of vascular hypertension was noted. As soon as the obstruction was solved, the gastric bleeding stopped. The authors discuss the clinical aspects and physiopathology of the gastric tube bleeding and, in particular, they evaluate the influence of the intestinal obstruction with vascular involvement on the development of this exceptional and severe complication.

Subtotal colectomy with antiperistaltic cecorectal anastomosis in the treatment of slow-transit constipation: long-term impact on quality of life.

BACKGROUND: The aim of the study was to evaluate the effectiveness of subtotal colectomy with cecorectal anastomosis (SCCA) in the treatment of slow-transit constipation, not just in terms of symptom resolution but also the overall impact on patients' quality of life. METHODS: Between 1991 and 2005, 43 patients underwent SCCA at our institution, 22 for slow-transit constipation (STC) and 21 for other types of colic diffuse disease (non-slow-transit constipation: NSTC), the latter being considered controls. A total of 29 patients (17 affected by STC) were administered a 50-item telephonic questionnaire, including the Gastrointestinal Quality of Life Index (GIQLI), the Wexner constipation and incontinence scale (WC, WI), and individual willingness to repeat the procedure. Questionnaire data and other parameters such as age, sex, length of follow-up, complications, and length of hospital stay were analyzed and compared, in order to evaluate possible correlations between the parameters and their related impact on quality of life, procedural effectiveness in terms of symptomatic regression, qualitative differences related to pathology (constipation versus non-constipation), and surgical approach (laparotomy versus video-laparo-assisted procedure). RESULTS: There were no procedure-related deaths in this series (mortality: 0%); however, we found two complications in the STC group (9.1%), one requiring reoperation. The GIQLI mean score for the STC group was 115.5 +/- 20.5 (mean score for healthy people 125.8 +/- 13), and the WC mean score passed from a preoperative value of 20.3 to a postoperative value of 2.6. Regression analysis revealed a significant correlation between GIQLI and urgency and abdominal pain, and abdominal pain correlated significantly with pathology (STC). A high number of patients (88.2% in STC) expressed a willingness to repeat the procedure given the same preoperative conditions. CONCLUSIONS: Comparing our results to those of the most homogeneous literature data, SCCA does not appear to be inferior to subtotal colectomy with ileorectal anastomosis (IRA) in terms of therapeutic effectiveness, postoperative mortality and morbidity, or overall impact on quality of life.

Palliative resection of colorectal cancer: does it prolong survival?

BACKGROUND: It is still a matter of debate as to whether resective surgery of the primary tumor may prolong the survival of patients affected by incurable colorectal cancer (CRC). The main goal of this retrospective study, carried out on patients not undergoing any therapy other than surgery, was to quantify the benefit of primary tumor removal in patients with differently presenting incurable CRC. METHODS: One hundred and thirty consecutive patients were operated on for incurable CRC (83 undergoing resective and 47 non-resective procedures). With the purpose of comparing homogenous populations and of identifying patients who may benefit from primary tumor resection, the patients were classified according to classes of disease, based on the "metastatic pattern" and the "resectability of primary tumor." RESULTS: In patients with "resectable" primary tumors, resective procedures are associated with longer median survival than after non-resective ones (9 months vs 3). Only patients with distant spread without neoplastic ascites/carcinosis benefit from primary tumor removal (median survival: 9 months vs 3). Morbidity and mortality of resective procedures is not significantly different from that of non-resective surgery, either in the population studied or in any of the groups considered. CONCLUSIONS: Palliative resection of primary CRC should be pursued in patients with unresectable distant metastasis (without carcinomatosis), and, intraoperatively, whenever the primary tumor is technically resectable.

Distinct molecular patterns based on proximal and distal sporadic colorectal cancer: arguments for different mechanisms in the tumorigenesis.

BACKGROUND AND AIMS: Colorectal cancer (CRC) ranks as the fourth most frequently diagnosed cancer worldwide. CRCs that arise proximally or distally to the splenic flexure show differences in epidemiologic incidence, morphology, and molecular alterations, suggesting the existence of two categories of CRC based on the site of origin. The aim of the present work is to investigate the histological and molecular differences between CRCs located proximally and distally to the splenic flexure, and their potential involvement in tumor prognosis and therapeutic strategies. METHODS: We evaluated 120 patients affected by sporadic CRC for clinicopathologic features, microsatellite instability (MSI), loss of heterozygosity (LOH) of chromosomes 18q, 8p, and 4p; they were also investigated for hMlh1, hMsh2, Fhit, p27, and Cox-2 immunostaining. RESULTS: The mucinous histotype was more frequent in the proximal than in the distal CRCs (p<0.004). The frequency of MSI phenotype was higher in proximal than in distal tumors (p<0.001); moreover, reduced or absent hMlh1, Fhit, p27 immunohistochemical expressions were more frequent in proximal than in distal tumors (p<0.001 and 0.01 for p27). In contrast, the frequency of LOH in 18q was higher in distal than in proximal tumors (p=0.002). No significant differences were observed between proximal and distal tumors in the frequency of LOH in 8p and altered expression of hMsh2 and p53 protein. CONCLUSION: These different features may reflect different genetic pathways of carcinogenesis and support the hypothesis of a different mechanism of cancer development between the proximal and the distal colon, with potential implications in the therapeutic approach.
