Revisional ileoanal pouch surgery: a systematic literature review assessing outcomes over the last 40 years.

AIM: Failure of primary ileal pouch-anal anastomosis (IPAA) occurs in up to 15% of patients. Revision surgery may be offered to patients wishing to maintain gastrointestinal continuity. This paper explores the literature relating to IPAA revision surgery, focusing on pouch function after revision and factors associated with pouch failure. METHODS: Search of PubMed database was carried out for 'ileal pouch anal anastomoses', 'ileoanal pouch', 'restorative proctocolectomy', 'revision surgery', 'redo surgery', 'failure', 'refashion surgery', 'reconstruction surgery' and 'salvage surgery'. Papers were screened using the PRISMA literature review strategy. Studies of adults published after 1980 in English with an available abstract were included. Case reports and studies that were superseded using the same data were excluded. RESULTS: Nineteen papers (1424 patients) were identified. Bowel motion frequency doubled following revision surgery compared to primary IPAA although the increase was not always statistically significant. In patients failing primary IPAA, frequency of daytime bowel motions improved following revision in three studies but only reached significance in one (12.1 vs. 6.9, P = 0.021). Risk of pouch failure is increased in patients who develop pelvic sepsis after the primary procedure with the largest study demonstrating a four-fold increased risk (hazard ratio 3.691, P < 0.0001). A final diagnosis of Crohn's causes a four-fold increased risk of pouch failure (n = 81; OR 3.92, 95% CI 1.1-15.9, P = 0.04). CONCLUSIONS: In patients undergoing revisional surgery, improved outcomes are observed but are inferior compared to primary IPAA patients. Pelvic sepsis after primary IPAA and a final diagnosis of Crohn's are associated with increased risk of pouch failure.

Radiotherapy for the treatment of distant nodes metastases from oligometastatic urothelial cancer: A retrospective case series.

OBJECTIVES: To investigate the efficacy of stereotactic body radiotherapy in oligometastatic urothelial carcinoma with node-only involvement. METHODS: We retrospectively collected data on the outcomes of patients who underwent stereotactic body radiotherapy for metastatic node lesions from oligometastatic urothelial carcinoma at Radiotherapy Unit of University Hospital of Parma, Parma, Italy. The investigated outcomes were lesion size, standardized uptake value, overall response rate, lesion control rate, lesion progression-free interval, progression-free survival and overall survival. RESULTS: Among seven patients included in the study, a total of 14 node metastatic lesions were treated with stereotactic body radiotherapy. The mean total dose of stereotactic body radiotherapy was 32 Gy (range 25-40 Gy). At first imaging evaluation, a mean variation of -4% (P = 0.427) in major diameter, -16% (P = 0.048) in minor diameter and -76% in standardized uptake value (P < 0.001) were documented. The overall response rate and lesion control rate were 43% and 100%, respectively. Median lesion progression-free interval, progression-free survival and overall survival were 11.4 months (95% CI 3.4-19.4), 2.9 months (95% CI 2.6-3.1) and 14.9 months (95% CI 12.3-17.5), respectively. Stereotactic body radiotherapy was effective in delaying the beginning of a systemic chemotherapy in four patients. CONCLUSIONS: The present findings generate the hypothesis of a possible role for the use of stereotactic body radiotherapy in selected patients with distant node metastases from oligometastatic urothelial carcinoma.

Sarcopenia is independently associated with poor preoperative physical fitness in patients undergoing colorectal cancer surgery.

BACKGROUND: Accurate preoperative risk assessment for major colorectal cancer (CRC) surgery remains challenging. Body composition (BC) and cardiopulmonary exercise testing (CPET) can be used to evaluate risk. The relationship between BC and CPET in patients undergoing curative CRC surgery is unclear. METHODS: Consecutive patients undergoing CPET prior to CRC surgery between 2010 and 2020 were identified between two different UK hospitals. Body composition phenotypes such as sarcopenia, myosteatosis, and visceral obesity were defined using widely accepted thresholds using preoperative single axial slice CT image at L3 vertebrae. Relationships between clinicopathological, BC, and CPET variables were investigated using linear regression analysis. RESULTS: Two hundred eighteen patients with stage I-III CRC were included. The prevalence of sarcopenia, myosteatosis, and visceral obesity was 62%, 33%, and 64%, respectively. The median oxygen uptake at anaerobic threshold (VO2 at AT) was 12.2 mL/kg/min (IQR 10.6-14.2), and oxygen uptake at peak exercise (VO2 peak) was 18.8 mL/kg/min (IQR 15.4-23). On univariate linear regression analysis, male sex (P < 0.001) was positively associated with VO2 at AT. While ASA grade (P < 0.001) and BMI (P = 0.007) were negatively associated with VO2 at AT, on multivariate linear regression analysis, these variables remained significant (P < 0.05). On univariate linear regression analysis, male sex (P < 0.001) was positively associated with VO2 peak, whereas age (P < 0.001), ASA grade (P < 0.001), BMI (P = 0.003), sarcopenia (P = 0.015), and myosteatosis (P < 0.001) were negatively associated with VO2 peak. On multivariate linear regression analysis age (P < 0.001), ASA grade (P < 0.001), BMI (P < 0.001), and sarcopenia (P = 0.006) were independently and negatively associated with VO2 peak. CONCLUSIONS: The novel finding that sarcopenia is independently associated with reduced VO2 peak performance in CPET supports the supposition that reduced muscle mass relates to poor physical function in CRC patients. Further work should be undertaken to assess whether sarcopenia diagnosed on CT can act as suitable surrogate for CPET to further enhance personalized risk stratification.

Radiotherapy after testis-sparing surgery for seminoma in monorchid patients: safety and efficacy.

PURPOSE: To evaluate local control and longitudinal endocrine data in monorchid patients treated with testicular-sparing surgery and adjuvant radiotherapy (RT) for seminomatous germ-cell tumors. METHODS: We searched our database established in 2009 for patients with seminoma who received testis irradiation following partial orchiectomy up to 2018. Eleven patients were identified. All had associated germ cell neoplasia in situ (GCNIS) in surrounding parenchyma. Analysis focused on local control and testosterone levels preservation after RT. We considered age, baseline (pre-RT) testosterone and luteinizing hormone (LH) levels, residual testicular volume, tumor size, and testosterone and LH levels trend over time in order to identify any association with endocrine impairment leading to hormonal replacement need. RESULTS: After a median follow-up of 21 months, no local or distant relapses were observed and hormonal function was maintained in 54.5% of patients (6/11). No significant interactions were observed for the investigated covariates. Notably, we observed an association between higher baseline testosterone levels and a decreased risk of exogenous androgen replacement (hazard ratio [HR] 0.409, 95% confidence interval [CI] 0.161-1.039, p = 0.060), whereas tumor size was associated with an increased risk of exogenous androgen replacement (HR 1.847, 95% CI 0.940-3.627, p = 0.075). CONCLUSIONS: Radiotherapy after testicular sparing surgery is effective in preventing local disease relapse in presence of GCNIS in the medium term. This strategy allows a preservation of adequate endocrine function in about half of patients. More patients and longer follow-up are needed to confirm these findings.

Surgical Assessment Units: The Key to More Efficient Emergency Surgical Provision and Admissions?

BACKGROUND: Hospitals establish surgical assessment units to promote efficiency and improve patient experience. Surgical assessment units are believed to reduce unnecessary admissions. We evaluated a hospital's on-call surgery service without this facility to determine benefits of implementation. METHODS: All emergency surgery referrals made over a 3-month period were recorded, including whether the patient was immediately discharged directly from emergency surgery. Data collection was undertaken by each surgical firm on-call. Immediate discharges were classed as patients not admitted to the hospital overnight (regardless of whether the patient had outpatient follow-up planned). RESULTS: Nine hundred eighty-four referrals were identified. Seven hundred ninety-three referrals had complete data and therefore were included for analysis. Of these, 349 patients (44.0% of referrals) were immediately discharged from emergency surgery, thereby preventing unnecessary admissions (a high proportion of surgical referrals not requiring hospital admission). This improves hospital efficiency, cost savings, and patient experience. Immediate discharge was less frequent and more difficult to accomplish if patients were initially assessed on wards (instead of in the emergency department). This is likely due to patients' perceptions that admission was required when transferred from emergency department to a ward. CONCLUSIONS: Establishment of surgical assessment units has multiple potential benefits to patients, hospitals and clinicians. Appropriateness of surgical assessment unit implementation by every hospital ought to be evaluated.

Treatment Outcome of metastatic lesions from renal cell carcinoma underGoing Extra-cranial stereotactic body radioTHERapy: The together retrospective study.

OBJECTIVES: stereotactic body radiation therapy (SBRT) use has increased overtime for the management of metastatic renal cell carcinoma (mRCC) patients, with a likely good control of irradiated lesions. We planned a retrospective multicenter Italian study, with the aim of investigating the outcome of treatment with SBRT for non-brain secondary lesions in mRCC patients. METHODS: all consecutive metastatic non-brain lesions from mRCC that underwent SBRT at nine Italian institutions from January 2015 to June 2017 were considered. The primary endpoint of the study was the lesion-PFS, calculated from SBRT initiation to the local progression of the irradiated lesion. RESULTS: 57 extracranial metastatic lesions from 48 patients with primary mRCC were treated with SBRT. At the median follow-up of 26.4 months, the median lesion-PFS was not reached (43 censored); 72.4% of lesions were progression-free at 40 months, with significantly better lesion-PFS for small metastatic lesions (<14 mm). SBRT was safe and the 1-year local disease control was 87.7%. After SBRT, 18 patients (37.5%) permanently interrupted systemic therapy. CONCLUSIONS: consistently with the previous literature, our findings support the use of SBRT in selected mRCC patients.

Double gallstone ileus.

BACKGROUND: Gallstone ileus remains a rare but important cause of intestinal obstruction. METHOD: We present a unique case of two gallstones causing intestinal obstruction at the same time. RESULTS: A 90-year-old lady presented with signs and symptoms of small bowel obstruction. At operation, two gallstones stuck at different points within the bowel were causing the obstruction and were removed. CONCLUSION: When operating on patients with small bowel obstruction from gallstone ileus, examination of the entire small bowel should be considered mandatory.

Laparoscopic feeding jejunostomy technique as part of staging laparoscopy.

Placement of a feeding jejunostomy tube is indicated for patients who need enteral access but where a gastrostomy is not feasible. This paper presents the technique and results of laparoscopic placement of feeding jejunostomy tubes in patients presenting with esophagogastric cancer. From December 2002 to February 2004, patients diagnosed with esophagogastric cancer with a potentially resectable lesion underwent staging laparoscopy. Laparoscopic feeding jejunostomy was performed on patients who were potential candidates for chemotherapy with palliative intent or neoadjuvant treatment prior to resection surgery. Surgical technique, recovery of bowel function, commencement of feeding jejunostomy, total time tube was in situ, and perioperative complications were analyzed. Of the 22 patients who underwent staging laparoscopy, a feeding jejunostomy tube was placed in 18. The remaining 4 patients were deemed to have advanced disease precluding any therapeutic options and underwent placement of esophageal stents. Feeding tubes remained in situ for a median time period of 76 days. Fourteen patients required enteral support and tubes were used for a median of 30 days. Complications from tube placement included 2 cases of wound infections, 1 of minor leak and 1 tube dislodgment. Patients were followed up for a median time of 112 days. Findings from current series suggest that placement of a feeding jejunostomy tube at the time of staging laparoscopy is a safe and reliable means of providing and maintaining nutrition for patients presenting with esophagogastric cancers.

Surgically proven complete response of stage III non-small cell lung cancer after cisplatin-enhanced radiotherapy. Clinical implications and long-term results.

AIMS AND BACKGROUND: Pathologic complete response in locally advanced non-small cell lung cancer is the main end point of combined therapies (chemotherapy and/or radiotherapy). Surgery after an induction treatment can improve local control, allowing the histologic assessment of treatment activity by means of resection or extensive biopsies. METHODS: Thirty patients surgically assessed without viable tumor after concurrent radiotherapy and continuous infusion of low-dose cisplatin, owing to an initially unresectable stage III non-small-cell lung cancer, were the object of evaluation to assess clinical implications, short- and long-term surgical results. RESULTS: The specificity rate of the preoperative restaging was 36.6%. The surgical procedures consisted of 22 resections and of extensive biopsies in 8 cases. The operative mortality was 4% (1/25) for procedures other than right pneumonectomy (3/5). No patient received postoperative chemotherapy. Eleven distant progressions, 4 local recurrences, and 4 new primary tumors were assessed as initial failures. The 8-year overall survival was 36%. CONCLUSIONS: Pathologic complete response after cisplatin-enhanced radiotherapy cannot be satisfactorily assessed by clinical means. Surgery is required to obtain a reliable evaluation; however, right pneumonectomy should be contraindicated because of prohibitive risk. Although an effective local treatment can cure patients with advanced stage III disease, the addition of chemotherapy seems advisable to improve tumor relapse control.

Laparoscopic repair of spontaneous vaginal evisceration of small bowel: report of a case.

Spontaneous vaginal evisceration of the small bowel is a rare event. It is precipitated in the postmenopausal woman commonly by hysterectomy and in the premenopausal woman by vaginal trauma. We report a case of a 75-year-old woman presenting with a protruding mass in her vagina and associated abdominal pain. A combined laparoscopic and transvaginal method of repair is described and the advantage of using both techniques highlighted.

The emergency surgical team - the way forward in emergency care?

INTRODUCTION: With reduced working hours and shift patterns, surgical training and continuity of patient care is being put at risk. We have devised a system for managing the emergency surgical patients in an effort to counteract these perceived problems. This study describes the emergency surgical team and audits its activity. PATIENTS AND METHODS: The emergency surgery team concept is described in detail. Over a 2-week period, general surgical referral data, patient management and operative activity were audited. RESULTS: A total of 229 patients were referred to the emergency surgical team with 159 treated conservatively, 45 underwent operative intervention and 25 were discharged without admission. Of the emergency surgical team referrals, 58% had gallstone pathology, appendicitis or constipation/non-specific abdominal pain. Average daily number of patients under the care of the emergency surgical team was 26 (range, 10-40). CONCLUSIONS: The consultant-led emergency surgical team look after many of the acutely sick surgical patients. Our system not only provides good teaching opportunities but ensures optimal continuity of patient care in a busy district general hospital. Such an approach to emergency surgical care has been successfully developed to optimise training opportunities and improve patient care in a setting of reduced working hours and shift systems in our hospital.

Mechanical bowel preparation for colorectal surgery: a meta-analysis on abdominal and systemic complications on almost 5,000 patients.

BACKGROUND: Several studies concluded that mechanical bowel preparation (MBP) does not confer any advantage on reducing the anastomotic leak rate or wound infections. The aim of this meta-analysis was to review all prospective randomised controlled trials on the use of MBP before colorectal surgery in order to find differences in the rates of abdominal and systemic complications in view of recent published articles. METHODS: Review of all randomised prospective trials compare MBP vs. non-MBP. Primary outcome measures were anastomotic leakages, abdomino-pelvic abscesses and postoperative ileus. Secondary outcomes were wound infections, extra-abdominal complications (urinary infections, pulmonary infections, deep venous thrombosis or pulmonary embolism, cardiac events), sepsis and mortality. RESULTS: Twelve articles met the inclusion criteria with 4,919 patients. The non-MBP group showed no significant increase of the anastomotic leakages (3.4% vs. 4.1%; p = NS) and wound infections (8.7% vs. 9.6%; p = NS) but had a lower rate of postoperative cardiac events (2.5% vs. 4.0%; p = 0.04). CONCLUSION: The evidence from recent studies, combined with previous ones, further suggests that the dogma of the necessity of mechanical bowel preparation before elective colorectal surgery should be reconsidered.

Proposal of a novel system for the staging of thymic epithelial tumors.

BACKGROUND: We designed and assessed a new TNM staging system (herein called the INT [Istituto Nazionale Tumori] system) for thymic epithelial tumors in order to overcome the perceived drawbacks of Masaoka's system, which represents the current standard. METHODS: In all, 123 cases were evaluated. The histologic types according to the World Health Organization (WHO) classification were as follows: subtype A: 5 cases; AB: 40; B1: 16; B2: 29; B3: 16; and C: 17 cases. There were 45 Masaoka's stage I, 33 stage II, 26 stage III, and 19 stage IV cases. A total of 11 INT definitions were grouped into three stages: locally restricted disease (75 cases), which included Masaoka's stage I and selected stage II cases (no pleural invasion); locally advanced disease (37 cases), which included Masaoka's stage III cases plus those staged II owing to pleural invasion and those staged IV owing to intrathoracic nodal or limited pleuropericardial involvement; and systemic disease (11 cases), which included the remaining Masaoka's stage IV cases. RESULTS: Completeness of resection, WHO types, and both staging systems were significant prognostic factors (p < 0.0001) on univariate analysis. The 95-month progression-free survival rates according to Masaoka's system were stage I: 100%; II: 93.6%; III: 46.3%; and IV: 23.2%. The INT system corresponding figures were as follows: locally restricted disease: 98.6%; locally advanced disease: 46.9%; and systemic disease: 11.7%. The INT system was the prognostic factor with the greatest impact (p = 0.0218) on multivariate analysis (Masaoka's system: p = 0.2012; completeness of resection: p = 0.6855; histology: p = 0.9386). CONCLUSIONS: The INT system allows finer disease descriptions than Masaoka's system, resulting in a stage grouping with higher prognostic distinctiveness.
