Background/Objectives: The textbook outcome (TO) is a composite tool introduced to uniform surgical units and regulate surgical quality and outcomes. A patient is considered TO only if all predetermined items are met. In colorectal surgery, TO represents a new tool that can achieve important results given the prevalence of colorectal cancers. However, at present, there is a lack of uniformity in the TO’s definition. This study utilized the Delphi process to define an Italian version of the TO in colorectal cancer. Methods: The survey consisted of two rounds of online questionnaires submitted to an expert panel in colorectal oncological surgery, renowned academic surgeons, who had attended multiple scientific conferences and who were authors of papers on this specific topic. Five main topics with 26 questions were investigated through an online modified Delphi method. Items with almost 75% agreement achieved consensus. Results: Twenty-eight Italian experts were selected and participated in the two rounds. The Italian version of the textbook outcome in colorectal surgery was defined as the presence of 90-day postoperative survival, negative margins and at least 12 lymph nodes, a minimally invasive approach, ostomy fashioning if preoperatively planned, postoperative complication < Clavien–Dindo 3b, at least 10 ERAS items, no readmission, proper CHT and RT regimens, complete colonoscopy after or before surgery and Tumor Board Evaluation. Conclusions: The textbook outcome in colorectal cancer patients is a quality instrument providing a complete overview of the care of such patients, from diagnosis to treatment. We hereby propose an Italian version of the TO with outcomes chosen by an expert panel.

Background: Since most anastomoses after left-sided colorectal resections are performed with a circular stapler, any technological change in stapling devices may influence the incidence of anastomotic adverse events. The aim of the present study was to analyze the effect of a three-row circular stapler on anastomotic leakage and related morbidity after left-sided colorectal resections. Materials and methods: A circular stapled anastomosis was performed in 4255 (50.9%) out of 8359 patients enrolled in two prospective multicenter studies in Italy, and, after exclusion criteria to reduce heterogeneity, 2799 (65.8%) cases were retrospectively analyzed through a 1:1 propensity score-matching model including 20 covariates relative to patient characteristics, to surgery and to perioperative management. Two well-balanced groups of 425 patients each were obtained: group (A) – true population of interest, anastomosis performed with a three-row circular stapler; group (B) – control population, anastomosis performed with a two-row circular stapler. The target of inferences was the average treatment effect in the treated (ATT). The primary endpoints were overall and major anastomotic leakage and overall anastomotic bleeding; the secondary endpoints were overall and major morbidity and mortality rates. The results of multiple logistic regression analyses for the outcomes, including the 20 covariates selected for matching, were presented as odds ratios (OR) and 95% confidence intervals (95% CI). Results: Group A versus group B showed a significantly lower risk of overall anastomotic leakage (2.1 vs. 6.1%; OR 0.33; 95% CI 0.15–0.73; P=0.006), major anastomotic leakage (2.1 vs. 5.2%; OR 0.39; 95% CI 0.17–0.87; P=0.022), and major morbidity (3.5 vs. 6.6% events; OR 0.47; 95% CI 0.24–0.91; P=0.026). Conclusion: The use of three-row circular staplers independently reduced the risk of anastomotic leakage and related morbidity after left-sided colorectal resection. Twenty-five patients were required to avoid one leakage.

Primary colorectal lymphoma is a rare neoplasm. We report the case of a fistula between a diffuse large B-cell lymphoma of the sigmoid colon and an ovarian teratoma. An emergent laparotomy for an acute abdomen in a 90-year-old woman was performed. A pelvic mass of 12 × 9 cm fistulized in the left colon was found with the presence of gas and free liquid within the abdomen. This is an extremely rare condition, and as far as we know, no cases of a fistula between a large B-cell colonic lymphoma and an ovarian teratoma are present in the literature.

The surgical treatment for patients with generalized peritonitis complicating sigmoid diverticulitis is currently debated; particularly in case of diffuse purulent contamination (Hinchey 3). Laparoscopic lavage and drainage (LLD) has been proposed by some authors as a safe and effective alternative to single- or multi-stage resective surgery. However, among all the different studies on LLD, there is no uniformity in terms of surgical technique adopted and data show significant differences in postoperative outcomes. Aim of this review was to analyze the differences and similarities among the authors in terms of application, surgical technique and outcomes of LLD in Hinchey 3 patients. A bibliographical research was performed by referring to PubMed and Cochrane. “Purulent peritonitis”, “Hinchey 3 diverticulitis”, “acute diverticulitis”, “colonic perforation” and “complicated diverticulitis” were used as key words. Twenty-eight papers were selected, excluding meta-analysis, reviews and case reports with a very small number of patients. The aim of this review was to establish how LLD should be done, suggesting important technical tricks. We found agreement in terms of indications, preoperative management, ports’ positioning, antibiotics, enteral feeding and drain management. On the contrast, different statements regarding indications, adhesiolysis and management of colonic hole and failure of laparoscopic lavage are reported. A widespread diffusion of LLD and standardization of its technique are impossible because of data heterogeneity and selection bias in the limited RCTs. It is necessary to wait for long terms results from randomized clinical trials (RCTs) in progress to establish the efficacy and safety of this technique. More importantly, an increased number of highly skilled and dedicated colorectal laparoscopic surgeons are required to standardized the procedure.

Background: Laparoscopic lavage was proposed in the 1990s to treat purulent peritonitis in patients with perforated acute diverticulitis. Prospective randomized trials had mixed results. The aim of this study was to determine the success rate of laparoscopic lavage in sepsis control and to identify a group of patients that could potentially benefit from this treatment. Methods: This retrospective multicentre international study included consecutive patients from 24 centres who underwent laparoscopic lavage from 2005 to 2015. Results: A total of 404 patients were included, 231 of whom had Hinchey III acute diverticulitis. Sepsis control was achieved in 172 patients (74·5 per cent), and was associated with lower Mannheim Peritonitis Index score and ASA grade, no evidence of free perforation, absence of extensive adhesiolysis and previous episodes of diverticulitis. The operation was immediately converted to open surgery in 19 patients. Among 212 patients who underwent laparoscopic lavage, the morbidity rate was 33·0 per cent; the reoperation rate was 13·7 per cent and the 30-day mortality rate 1·9 per cent. Twenty-one patients required readmission for early complications, of whom 11 underwent further surgery and one died. Of the 172 patients discharged uneventfully after laparoscopic lavage, a recurrent episode of acute diverticulitis was registered in 46 (26·7 per cent), at a mean of 11 (range 2–108) months. Relapse was associated with younger age, female sex and previous episodes of acute diverticulitis. Conclusion: Laparoscopic lavage showed a high rate of successful sepsis control in selected patients with perforated Hinchey III acute diverticulitis affected by peritonitis, with low rates of operative mortality, reoperation and stoma formation.

Background. Hartmann’s procedure (HP) followed by reversal restoration is the first choice for treatment of diffuse diverticular peritonitis. There is no unanimous consensus regarding the use of laparoscopy to treat the same condition. Methods. Data from 60 patients with diverticular diffuse peritonitis who underwent urgent HP followed by laparoscopic reversal were retrospectively analyzed. Patients were divided into 2 groups according to the open or laparoscopic HP (OHP, 24 patients; LHP, 36 patients). Outcomes were measured in terms of functional recovery, morbidity, mortality, and length of hospital stay. Results. HPs showed no differences among the groups in terms of operative time, blood loss, and length of intensive care unit stay. Overall morbidity was significantly lower in LHP than in OHP, corresponding to 33.3% and 66.7% respectively (P = .018). The incidence of both surgical and medical complications was higher in OHP than in LHP (41.7% vs 22.2% [P = .044] and 45.8% vs 24.3% [P = .023], respectively). Mortality was 16.6% for each group. LHP showed a faster return to bowel movements and a shorter hospital stay than OHP. The secondary intestinal reversal was possible in 92% of cases, successfully completed laparoscopically in 91.3%. No patients of LHP group required a conversion to open intestinal reversal. Conclusion. LHP for treatment of diverticular diffuse peritonitis showed significantly lower morbidity, faster recovery, shorter hospital stay, and higher rates of successful laparoscopic reversal when compared with OHP.

Background: Anastomotic leakage is one of the most serious complications after rectal cancer surgery. Method: A prospective multicenter interventional study to assess a newly described technique of creating the colorectal and coloanal anastomosis. The primary outcome was to access the safety and efficacy of this technique in the reduction of anastomotic leak. Result: Fifty-three patients with rectal cancer who underwent low or ultra-low anterior resection were included in the study. There were 35 males and 18 females, with a median age of 68 years (range = 49-89 years). The median tumor distance from the anal verge was 8 cm (range = 4-12 cm), and the median body mass index was 24 kg/m² (range = 20-35 kg/m²). Thirty patients underwent open, 16 laparoscopic, and 7 robotic surgeries. Multiple firing (2-charges) was required in 30 patients to obtain a complete rectal division. Forty-five patients had colorectal anastomosis, and 8 patients had coloanal anastomosis. The protective ileostomy was created in 40 patients at the time of initial surgery. There was no mortality in the first 30 days postoperatively, and only 10 (19%) patients developed complications. There were 3 anastomotic leakages (6%); 2 of them were subclinical with ileostomy created at initial operation and both were treated conservatively with transanal drainage and intravenous antibiotics. One patient required reoperation and ileostomy. The median length of hospital stay was 10 days (range = 4-20 days). Conclusion: Our technique is a safe and efficient method of creation of colorectal anastomosis. It is also a universal method that can be used in open, laparoscopic, and robotic surgeries.
