ABSTRACT
BACKGROUND: Despite the recent advances in medical therapy, the majority of patients with Crohn's disease (CD) still require surgery during the course of their life. While a correlation between early primary surgery and lower recurrence rates has been shown, the impact of surgical timing on postoperative complications is unclear. The aim of this study is to assess the impact of surgical timing on 30-day postoperative morbidity. METHODS: This is a retrospective analysis of a prospectively collected database of 307 consecutive patients submitted to elective primary ileocolic resection for CD at our institution between July 1994 and July 2018. The following variables were considered: age, gender, year of treatment, smoking habits, preoperative steroid therapy, presence of fistula or abscess, type of anastomosis, and time interval between diagnosis of CD and surgery. Univariate and multivariate logistic regressions were performed to examine the association between risk factors and complications. RESULTS: Major complications occurred in 29 patients, while anastomotic leak was observed in 16 patients. Multivariate logistic regression analysis showed that surgical timing in years (OR 1.10 p = 0.002 for a unit change), along with preoperative use of steroids (OR 5.45 p < 0.001) were independent risk factors for major complications. Moreover, preoperative treatment with steroids (6.59 p = 0.003) and surgical timing (OR 1.10 p = 0.023 for a unit change) were independently associated with anastomotic leak, while handsewn anastomosis (OR 2.84 p = 0.100) showed a trend. CONCLUSIONS: Our results suggest that the longer is the time interval between diagnosis of CD and surgery, the greater is the risk of major surgical complications and of anastomotic leak.

INTRODUCTION: Transverse colon cancer (TCC) is poorly studied, and TCC cases are often excluded from large prospective randomized trials because of their complexity and their potentially high complication rate. The best surgical approach for TCC has yet to be established. The aim of this large retrospective multicenter Italian series is to investigate the advantages and disadvantages of both hemicolectomy and transverse colectomy in order to identify the best surgical approach. MATERIALS AND METHODS: This was a retrospective cohort study of patients with mid-transverse colon cancer treated with a segmental colon resection or an extended hemicolectomy (right or left) between 2006 and 2016 in 28 high-volume (more than 70 procedures/year) Italian referral centers for colorectal surgery. RESULTS: The study included 1529 patients, 388 of whom underwent a segmental resection while 1141 underwent an extended resection. A higher number of complications has been reported in the segmental group than in the extended group (30.1% versus 23.6%; p 0.010). In 42 cases the main complication was the anastomotic leak (4.4% versus 2.2%; p 0.020). Recovery outcomes also showed statistical differences: time to first flatus (p 0.014), time to first mobilization (p 0.040), and overall hospital stay (p < 0.001) were significantly shorter in the extended group. Even if overall survival were similar between the groups (95.1% versus 97%; p 0.384), 3-year disease-free survival worsened after segmental resection (78.1% versus 86.2%; p 0.001). CONCLUSIONS: According to our results, an extended right colon resection for TCC seems to be surgically safer and more oncologically valid.

BACKGROUND: Laparoscopic right hemicolectomy is a commonly performed procedure. Little is known on how to perform the enterotomy closure after stapled side-to-side intracorporeal anastomosis. METHOD: A multicentric case-controlled study has been designed to compare different ways to fashion enterotomy closure: double layer versus single layer, sewn versus stapled, and robotic versus laparoscopic approach. Furthermore, additional characteristics including sutures' materials, interrupted versus running suture and the presence of deep corner suture has been investigated. RESULTS: We collected data for 1092 patients who underwent right hemicolectomy at ten centers. We analyzed 176 robotic against 916 laparoscopic anastomosis: no significant differences were found in terms of bleedings (p = 0.455) and anastomotic leak (p = 0.405). We collected data from 126 laparoscopic sewn single-layer versus 641 laparoscopic sewn double-layer anastomosis: a significant reduction was recorded in terms of leaks in double-layer group (p = 0.02). About double-layer characteristics, we found a significant reduction of bleedings (p = 0.008) and leaks (p = 0.017) with a running suture; similarly, a reduction of bleedings (p = 0.001) and leaks (p = 0.005) was observed with the usage of deep corner closure. The presence of a barbed suture thread seemed to significantly reduce both bleedings (p = 0.001) and leaks (p = 0.001). We found no significant differences in terms of bleedings (p = 0.245) and anastomotic leak (p = 0.660) comparing sewn versus stapled anastomosis. CONCLUSIONS: Fashioning a stapled ileocolic intracorporeal anastomosis, we can recommend the adoption of a double-layer enterotomy closure using a running barbed suture in the first layer. Totally, stapled closure and robotic assistance have to be considered a non-inferior alternative.

AIM: Transanal endoscopic microsurgery (TEM) was originally invented by Buess et al. (Chirurg, 1984, 55, 677-80) for the treatment of infraperitoneal rectal adenomas. Its indications have progressively expanded to include larger and more advanced lesions. The aim of the study was to report the results of TEM used for the treatment of circumferential rectal lesions. METHOD: We retrospectively reviewed the medical records of 17 consecutive patients [median age 69 (32-89) years; nine men] who underwent TEM for a circumferential rectal lesion in our department between September 2010 and January 2015. RESULTS: The median distance from the anal verge was 4 (3-11) cm, the median longitudinal extent was 7 (3-10) cm and the median surface area was 75 (40-255) cm(2) . An end-to-end anastomosis without proximal bowel mobilization was completed endoscopically in all cases. The median operating time was 120 (40-240) min. Persistent, endoscopically uncontrollable endoluminal bleeding in one patient was successfully treated with a second TEM procedure. One patient underwent preoperative radiotherapy for adenocarcinoma detected at the preoperative assessment. Surgical histology showed a pT3 cancer in one patient who refused further surgery, a pT2 cancer in two who subsequently underwent abdominoperineal resection, a pT1 cancer in four and a ypT0 in one patient. All are at present free of disease. No patients developed faecal incontinence or urinary or sexual dysfunction. Four patients required endoscopic balloon dilatation for stenosis. CONCLUSION: Transanal endoscopic microsurgery is a feasible and safe technique for large circumferential lesions with a satisfactory outcome. Preoperative staging may be inaccurate.

The comparison between idiopathic achalasia (IA) and Chagas' disease esophagopathy (CDE) may evaluate if treatment options and their outcomes can be accepted universally. This study aims to compare IA and CDE at the light of high-resolution manometry. We studied 86 patients with achalasia: 45 patients with CDE (54% females, mean age 55 years) and 41 patients with IA (58% females, mean age 49 years). All patients underwent high-resolution manometry. Upper esophageal sphincter parameters were similar (basal pressure CDE = 72 ± 45 mmHg, IA = 82 ± 57 mmHg; residual pressure CDE = 9.9 ± 9.9 mmHg, IA = 9.8 ± 7.5 mmHg). In the body of the esophagus, the amplitude was higher in the IA group than the CDE group at 3 cm (CDE = 15 ± 14 mm Hg, IA = 42 ± 52 mmHg, P = 0.003) and 7 cm (CDE = 16 ± 15 mmHg, IA = 36 ± 57 mmHg, P = 0.04) above the lower esophageal sphincter (LES). The LES basal pressure (CDE = 17 ± 16 mmHg, IA = 40 ± 22 mmHg, P < 0.001) and residual pressure (CDE = 12 ± 11 mmHg, IA = 27 ± 13 mmHg, P < 0.001) were also higher in the IA group. Our results show that: (i) there is no difference in regards to the upper esophageal sphincter; (ii) higher pressures of the esophageal body are noticed in patients with IA; and (iii) basal and residual pressures of the LES are lower in patients with CDE. Our results did not show expressive manometric differences between IA and CDE. Some differences may be attributed to a more pronounced esophageal dilatation in patients with CDE.

Patients with suspected gastroesophageal reflux disease (GERD) should undergo a thorough preoperative workup. After establishing the diagnosis, the treatment should be individualized and a decision about an operation made jointly between surgeon and patient. The indications for surgery have changed in the last twenty years, as the minimally invasive approach to antireflux surgery has allowed good control of reflux with a short hospital stay, fast recovery and excellent long term results. This article reviews the current status on diagnosis and treatment of GERD in the United States.

The aim of oncologic surgery is radical cancer treatment with preservation of function and quality of life. Almost 30 years ago, transanal endoscopic microsurgery (TEM) revolutionised the technique and outcomes of transanal surgery, first becoming the standard of treatment for large rectal adenomas, then offering a possibly curative treatment for early rectal cancer, and finally generating discussion on its potential role in combination with neoadjuvant therapies for the treatment of more invasive cancer. TEM afforded the advantage of combining a less invasive transanal approach with low recurrence rates thanks to enhanced visualization of the surgical field, which allows more precise dissection. We describe the current indications, the preoperative work-up, the surgical technique (with the aid of a video), postoperative management and results obtained in an over 20-year-long experience. Designed as an accurate means to allow excision of benign rectal neoplasms with a very low morbidity rate, TEM today is indicated as a curative treatment of malignant neoplasms that are histologically confirmed as pT1 sm1 carcinomas. T1 sm2-3 and T2 lesions should at present be included in prospective trials. Accurate preoperative staging is essential for optimal selection of patients. Patients with clear indication for TEM should be referred to specialized medical centres experienced with the technique.

BACKGROUND: Of the few studies that have investigated quality-of-life (QoL) outcomes after transanal endoscopic microsurgery (TEM), the majority have reported only short-term follow-up data. This study assessed long-term clinical and instrumental outcomes (QoL, sexual, urinary and sphincter function) after TEM for extraperitoneal rectal cancer. METHODS: Preoperative and postoperative anorectal function was assessed in consecutive patients with benign rectal lesions or early rectal cancer, based on clinical scores and anorectal manometry. RESULTS: Between January 2000 and July 2005, 93 patients undergoing TEM completed the 60-month study protocol. The mean Wexner continence score increased from baseline at 3 months, began to decline within 12 months, and had returned to the preoperative value at 60 months. Urgency was reported by 65·0, 30·0 and 5 per cent of patients at 3, 12 and 60 months respectively (P < 0·050). A significant improvement was noted in various clinical and QoL scores at 12 and 60 months. Postoperative manometry values at 3 months were significantly lower than at baseline (P < 0·050), but had returned to preoperative values at 12 months. Tumour size of 4 cm or above was the only factor that significantly (P = 0·008) affected the rectal sensitivity threshold, the urge to defaecate threshold and the maximum tolerated volume at 3 months after TEM. CONCLUSION: TEM had no long-term effect on anorectal function or QoL. Lower anal resting pressure at early follow-up was not associated with defaecation problems in patients who were continent before surgery.

BACKGROUND/AIMS: Transanal endoscopic microsurgery is a minimally invasive technique that allows the excision of benign and selected malignant tumours. We present a study for evaluating surgical morbidity, mortality and local recurrence rate of patients with rectal adenomas treated with transanal endoscopic microsurgery in six different Italian centres following the same protocol. METHODS: A total of 882 patients with rectal lesions (adenomas and early stage of carcinomas) underwent transanal endoscopic microsurgery in six different Surgical Departments from January 1993 to October 2004. Five hundred and ninety patients had preoperative diagnosis of adenomas but 588 patients were regularly followed up to determine treatment efficacy in terms of local recurrence rate. RESULTS: The study involved 588 patients, with a median age of 66 years (25th percentile-75th percentile=58-71 years). No postoperative mortality was reported. Intraoperative complications were observed in three patients (0.5%). Minor complications occurred in 48 patients (8.2%) whereas major complications were found only in 7 patients (1.2%). Definitive histology confirmed adenomas in 530 cases (90.1%). Two patients (0.3%) were lost to follow-up so were not included in the paper. At median follow-up of 44 months (25th percentile-75th percentile=15-74 months), 23 (4.3%) adenomas recurred and were successfully retreated by transanal endoscopic microsurgery [20 cases (87%)] and by conventional surgery [3 patients (13%)]. No further recurrences were observed at subsequent follow-up. Thirty-one (5.3%) patients died during follow-up for old age, cardiac disease, etc. CONCLUSIONS: Transanal endoscopic microsurgery is, in our experience, an effective method for local resection of benign rectal tumours with morbidity of 11.4%, no postoperative mortality and with a percentage of local recurrence of 4.3%.

BACKGROUND: The role of laparoscopic resection (LR) in the management of extraperitoneal rectal cancer still is unclear. This study aimed to compare perioperative and long-term results of laparoscopic and open resection (OR) for low and midrectal cancer. METHODS: A prospective nonrandomized trial comparing patients submitted to OR or LR for low and midrectal cancer at a single institution was conducted. RESULTS: The study included 191 consecutive patients: 98 patients who underwent LR and 93 who underwent OR. The mean follow-up period was 46.3 months for LR and 49.7 months for OR. The conversion rate for LR was 18.4%. With the use of LR, the mean time for complete patient mobilization was shorter (1.7 vs 3.3 days; p < 0.001) and patients were earlier in passing flatus (2.6 vs 3.9 days; p < 0.001) and stools (3.8 vs 4.7 days; p < 0.01), and in resuming oral intake (3.4 vs 4.8 days; p < 0.001). The mean hospital stay was shorter for LR, but the difference did not reach significance (11.4 vs 13 days). Morbidity and mortality rates were similar: LR (24.4% and 1%) and OR (23.6% and 2.2%). Laparoscopic patients presented a higher rate of anastomotic fistulas (13.5% vs 5.1%) and reoperations (6.1% vs 3.2%) but the difference was statistically nonsignificant. Laparoscopic resection presented a significantly lower local recurrence rate (3.2% vs 12.6%; p < 0.05). The cumulative survival and disease-free rates at 5 years were, respectively, 80% and 65.4% after LR and 68.9% and 58.9% after OR (nonsignificant difference). Stage-by-stage comparison showed prolonged cumulative survival for stages III and IV cancer in LR (82.5% vs 40.5%; p = 0.006 and 15.8% vs 0%; p = 0.013, respectively) and a reduced rate of cancer-related death for stage III in LR (11.4% vs 51.9%; p = 0.001). CONCLUSIONS: As compared with conventional open surgery, LR for low and midrectal cancer is characterized by a faster recovery and similar overall morbidity (but a higher rate of anastomotic leakages), and does not present any adverse oncologic effect.
