Laparoscopic Hartmann's reversal has better clinical outcomes compared to open surgery: An international multicenter cohort study involving 502 patients.

Background: Hartmann's procedure (HP) is used in surgical emergencies such as colonic perforation and colonic obstruction. "Temporary" colostomy performed during HP is not always reversed in part due to potential morbidity and mortality associated with reversal. There are several contributing factors for patients requiring a permanent colostomy following HP. Therefore, there is still some discussion about which technique to use. The aim of this study was to evaluate perioperative variables of patients undergoing Hartmann's reversal using a laparoscopic and open approach. Methods: The multicenter retrospective cohort study was done between January 2009 and December 2019 at 14 institutions globally. Patients who underwent Hartmann's reversal laparoscopic (LS) and open (OS) approaches were evaluated and compared. Sociodemographic, preoperative, intraoperative variables, and surgical outcomes were analyzed. The main outcomes evaluated were 30-day mortality, length of stay, complications, and postoperative outcomes. Results: Five hundred and two patients (264 in the LS and 238 in the OS group) were included. The most prevalent sex was male in 53.7%, the most common indication was complicated diverticular disease in 69.9%, and 85% were American Society of Anesthesiologist (ASA) II-III. Intraoperative complications were noted in 5.3% and 3.4% in the LS and OS groups, respectively. Small bowel injuries were the most common intraoperative injury in 8.3%, with a higher incidence in the OS group compared with the LS group (12.2% vs. 4.9%, p < 0.5). Inadvertent injuries were more common in the small bowel (3%) in the LS group. A total of 17.2% in the OS versus 13.3% in the LS group required intensive care unit (ICU) admission (p = 0.2). The most frequent postoperative complication was ileus (12.6% in OS vs. 9.8% in LS group, p = 0.4)). Reintervention was required mainly in the OS group (15.5% vs. 5.3% in LS group, p < 0.5); mortality rate was 1%. Conclusions: Laparoscopic Hartmann's reversal is safe and feasible, associated with superior clinical outcomes compared with open surgery.

Quality of Life After Elective Laparoscopic Sigmoidectomy for Symptomatic Uncomplicated Diverticular Disease.

INTRODUCTION: Symptomatic uncomplicated diverticular disease (SUDD) is characterized by abdominal pain and altered bowel function and may affect quality of life. When symptoms are severe and conservative therapy is ineffective, surgical intervention becomes an option. OBJECTIVE: This study aims to investigate quality of life after elective sigmoidectomy for patients affected by SUDD. MATERIALS AND METHODS: Retrospective multicenter review of consecutive patients affected by SUDD that underwent elective laparoscopic sigmoidectomy from January 2015 to March 2018. SUDD was defined as the presence of diverticula with persistent localized pain and diarrhea or constipation without macroscopic inflammation. Quality of life was investigated using the Gastrointestinal Quality of Life Index questionnaire at baseline, and at 6 and 12 months after surgery. Readmissions, unplanned clinical examination, mesalazine resumption, and emergency department visit for abdominal symptoms were recorded. RESULTS: Fifty-two patients were included in the analysis. Gastrointestinal Quality of Life Index score at 6 months from surgery did not statistically differ from baseline (96±10.2 vs. 89±11.2; P>0.05), while patients reported a better quality of life at 12 months after surgery (109±8.6; P<0.05). Within the first year of follow-up, 3 patients (5.8%) were readmitted for acute enteritis, 8 patients (15.4%) had emergency room access for abdominal pain, and 8 patients had unplanned outpatients' medical examinations for referred lower abdominal pain and bowel changes. Mesalazine was resumed in 17.3% of patients. CONCLUSION: Elective laparoscopic sigmoidectomy for SUDD is safe and effective in improving quality of life, although in some cases symptoms may persist.

High Versus Low Ligation of the Inferior Mesenteric Artery During Rectal Resection for Cancer: Oncological Outcomes After Three Years of Follow-Up From the HIGHLOW Trial.

Objectives: To determine the disease-free survival (DFS), disease-specific survival (DSS), and recurrence in patients who underwent laparoscopic low anterior rectal resection with total mesorectal excision (TME) with either high or low ligation of the inferior mesenteric artery (IMA). Background: The level of IMA ligation during anterior rectal resection with TME is still a matter of debate, especially in terms of oncological adequacy. Methods: Between June 2014 and December 2016, patients scheduled to undergo elective laparoscopic low anterior resection (LAR) and TME in 6 Italian nonacademic hospitals were randomized into 2 groups in the HIGHLOW Trial (ClinicalTrials.gov Identifier: NCT02153801) according to the level of IMA ligation: high ligation (HL) versus low ligation (LL). DFS, DSS, and recurrence were inquired. Recurrence was determined at 3, 6, 9, and 12 months and every 6 months thereafter. Patients and tumor characteristics as well as surgical outcomes were analyzed to identify risk factors for recurrence. Results: One hundred ninety-six patients from the HIGHLOW trial were analyzed. Median follow-up for DFS was 40.6 (interquartile range [IQR], 6-64.7) and 40 (IQR, 7.6-67.8), while median follow-up for DSS was 41.2 (IQR, 10.7-64.7) and 42.7 (IQR, 6-67.6) in the HL and LL groups, respectively. The 3-year DFS rate of HL and LL patients was 82.2% and 82.1% (P = 0.874), respectively. The 3-year DSS for HL and LL patients was 92.1% and 93.4% (P = 0.897), respectively. There was no statistically significant difference in the local recurrence rate (2% HL vs 2.1% LL), in the regional recurrence rate (3% HL vs 2.1% LL), and in the distant recurrence rate (12.9% HL vs 13.7% LL). Multivariate analysis found conversion to open surgery (hazard ratio [HR], 3.68; P = 0.001) and higher stage of disease (HR, 7.73; P < 0.001) to be significant determinant for DFS. Conclusions: The level of inferior mesenteric artery ligation during LAR and TME for rectal cancer does not affect DFS, DSS, and recurrence.

Symptomatic Uncomplicated Diverticular Disease and Incidence of Unexpected Abscess during Sigmoidectomy: A Multicenter Prospective Observational Study.

BACKGROUND: Symptomatic uncomplicated diverticular disease can affect patients' everyday routine. Considerable efforts have been made to identify clinical features that correlate to the severity of the disease. Unexpected intraoperative abscesses are reported in large retrospective series, showing how uncomplicated symptoms and presentations can underlie a complicated disease. The aim of this study was to investigate the incidence of pericolic or intramural abscess in patients undergoing elective sigmoidectomy for symptomatic uncomplicated diverticular disease and see if chronic symptoms correlate to the presence of an abscess. METHODS: Between January 2016 and June 2018, we prospectively collected data of patients who were given indication to elective sigmoidectomy for symptomatic uncomplicated diverticular disease. Patients were divided into 3 groups: acute resolving, smoldering, and atypical according to a previously described classification of uncomplicated diverticular disease. RESULTS: One hundred fifty-eight consecutive patients were enrolled in the study. The median age was 63 years (22- 88), and the mean body mass index was 26 (±7) kg/m2. There were 114 patients in the acute resolving group, 36 in the smoldering group, and 8 in the atypical group. An unexpected abscess was reported in 75 patients (47.5%) during surgery or pathological examination. The incidence of -abscess was greater for patient in the smoldering group (p = 0.0243). CONCLUSION: Our series of patients affected by symptomatic uncomplicated diverticular disease showed an incidence of unexpected pericolic or intramural abscess of 47.5%. Patients affected by smoldering diverticular disease presented a greater abscess rate.

Low Ligation of Inferior Mesenteric Artery in Laparoscopic Anterior Resection for Rectal Cancer Reduces Genitourinary Dysfunction: Results From a Randomized Controlled Trial (HIGHLOW Trial).

OBJECTIVES: The aim of the present study was to compare the incidence of genitourinary (GU) dysfunction after elective laparoscopic low anterior rectal resection and total mesorectal excision (LAR + TME) with high or low ligation (LL) of the inferior mesenteric artery (IMA). Secondary aims included the incidence of anastomotic leakage and oncological outcomes. BACKGROUND: The criterion standard surgical approach for rectal cancer is LAR + TME. The level of artery ligation remains an issue related to functional outcome, anastomotic leak rate, and oncological adequacy. Retrospective studies failed to provide strong evidence in favor of one particular vascular approach and the specific impact on GU function is poorly understood. METHODS: Between June 2014 and December 2016, patients who underwent elective laparoscopic LAR + TME in 6 Italian nonacademic hospitals were randomized to high ligation (HL) or LL of IMA after meeting the inclusion criteria. GU function was evaluated using a standardized survey and uroflowmetric examination. The trial was registered under the ClinicalTrials.gov Identifier NCT02153801. RESULTS: A total of 214 patients were randomized to HL (n = 111) or LL (n = 103). GU function was impaired in both groups after surgery. LL group reported better continence and less obstructive urinary symptoms and improved quality of life at 9 months postoperative. Sexual function was better in the LL group compared to HL group at 9 months. Urinated volume, maximum urinary flow, and flow time were significantly (P < 0.05) in favor of the LL group at 1 and 9 months from surgery. The ultrasound measured post void residual volume and average urinary flow were significantly (P < 0.05) better in the LL group at 9 months postoperatively. Time of flow worsened in both groups at 9 months compared to baseline. There was no difference in anastomotic leak rate (8.1% HL vs 6.7% LL). There were no differences in terms of blood loss, surgical times, postoperative complications, and initial oncological outcomes between groups. CONCLUSIONS: LL of the IMA in LAR + TME results in better GU function preservation without affecting initial oncological outcomes. HL does not seem to increase the anastomotic leak rate.

Is laparoscopic surgery really effective for the treatment of colon and rectal cancer in very elderly over 80 years old? A prospective multicentric case-control assessment.

BACKGROUND: To evaluate the effectiveness of laparoscopic surgery (LCS) for colon and rectal cancer in the very elderly over 80 years old. METHODS: We performed a prospective multicentric analysis comparing patients over 80 years (Group A) and patients between 60 and 69 years (Group B) undergoing LCS for cancer from January 2008 to December 2013. Colon and rectal cancers were analyzed separately. Comorbidity and complications were classified using the Charlson comorbidity index (CCI) and the Clavien-Dindo system, respectively. Oncological parameters included tumor-free margins, number of lymph nodes harvested and circumferential resection margin. RESULTS: Group A included 96 and 33 patients, and Group B 220 and 82 for colon and rectal cancers, respectively. Groups were similar except for ASA score and CCI, as expected. There was no significant difference in operative time [colon; rectum] (180[IQR 150-200] vs 180[150-210] min; NS-180[160-210] vs 180[165-240] min; NS), estimated blood loss (50[25-75] vs 50[25-120] mL; NS-50[0-150] vs 50[25-108.7] mL; NS) and conversion rate (2.1 vs 2.7 %; NS-3.0 vs 2.4 %; NS). Timing of first stool (3[2-3.25] vs 3[2-5] dd; NS-3[2-4] vs 3[2-5] dd; NS), length of stay (7[6-8] vs 7[6-8] dd; NS-8[8-9] vs 8[7-9] dd; NS) and readmission rate (1.0 vs 0.45 %; NS-6.1 vs 1.2 %; NS) were similar. Tumor-free margins were appropriate, and positivity of CRM is poor (6.1 vs 4.9; NS). We did not record significant differences in complications rate (47.9 vs 43.6 %; NS-63.6 vs 52.4 %; NS). CONCLUSIONS: Laparoscopic surgery is effective for the treatment of colorectal cancer even in the very elderly. Age is not a risk factor or a limitation for LCS.

Effectiveness of elective laparoscopic treatment for colonic diverticulitis.

BACKGROUND AND OBJECTIVES: To analyze the short- and long-term outcomes of laparoscopic sigmoid colectomy for the elective treatment of diverticular disease. METHODS: A consecutive unselected series of 94 patients undergoing elective laparoscopic sigmoid colectomy for diverticular disease from 2008 to 2012 was analyzed. We collected patients-, surgery- and hospital stay-related data, as well as the short- and long-term outcomes. Operative steps, instrumentation, and postoperative cares were standardized. Comorbidity was assessed by Charlson comorbidity index. Complications were classified using the Clavien-Dindo classification system. The qualitative long-term assessment was carried out by subjecting patients to the validated gastrointestinal quality of life index questionnaire before and after surgery. RESULTS: The mean age of our cohort was 61.3 ± 11.0 years with a Charlson comorbidity index of 1.2 ± 1.5. Mean operative time was 213.5 ± 60.8 minutes and estimated blood loss was 67.2 ± 94.3 mL. We had 3 cases (3.2%) of conversion to open laparotomy. The rates of postoperative complications were 35.1%, 6.3%, 2.1%, and 1.06%, respectively, for grades 1, 2, 3b, and 5 according to the Clavien-Dindo system. Length of hospital stay was 8.1 ± 1.9 days, and we have not recorded readmissions in patients discharged within 60 days after surgery. Median follow-up was of 9.6 ± 2.7 months. We observed no recurrence of diverticular disease, but there was evidence of 3 cases of incisional hernia (3.19%). The difference between preoperative and late gastrointestinal quality of life index score was statistically significant (97.1 ± 5.8 vs 129.6 ± 8.0). CONCLUSIONS: Elective laparoscopic treatment of colonic diverticular disease represents an effective option that produces adequate postoperative results and ensures a satisfactory functional outcome.

"High or low Inferior Mesenteric Artery ligation in Laparoscopic low Anterior Resection: study protocol for a randomized controlled trial" (HIGHLOW trial).

BACKGROUND: The position of arterial ligation during laparoscopic anterior rectal resection with total mesorectal excision can affect genito-urinary function, bowel function, oncological outcomes, and the incidence of anastomotic leakage. Ligation to the inferior mesenteric artery at the origin or preservation of the left colic artery are both widely performed in rectal surgery. The aim of this study is to compare the incidence of genito-urinary dysfunction, anastomotic leak and oncological outcomes in laparoscopic anterior rectal resection with total mesorectal excision with high or low ligation of the inferior mesenteric artery in a controlled randomized trial. METHODS/DESIGN: The HIGHLOW study is a multicenter randomized controlled trial in which patients are randomly assigned to high or low inferior mesenteric artery ligation during laparoscopic anterior rectal resection with total mesorectal excision for rectal cancer. Inclusion criteria are middle or low rectal cancer (0 to 12 cm from the anal verge), an American Society of Anesthesiologists score of I, II, or III, and a body mass index lower than 30. The primary end-point measure is the incidence of post-operative genito-urinary dysfunction. The secondary end-point measure is the incidence of anastomotic leakage in the two groups. A total of 200 patients (100 per arm) will reliably have 84.45 power in estimating a 20% difference in the incidence of genito-urinary dysfunctions. With a group size of 100 patients per arm it is possible to find a significant difference (α = 0.05, ß = 0.1555). Allowing for an estimated dropout rate of 5%, the required sample size is 212 patients. DISCUSSION: The HIGHLOW trial is a randomized multicenter controlled trial that will provide evidence on the merits of the level of arterial ligation during laparoscopic anterior rectal resection with total mesorectal excision in terms of better preserved post-operative genito-urinary function. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02153801 Protocol Registration Receipt 29/5/2014.

Totally laparoscopic resection of the splenic flexure for tumor.

Colonic tumors located at the splenic flexure are rare and show a higher occlusive risk than other colorectal cancers. The totally laparoscopic segmental resection of splenic flexure represents a challenging procedure that requires adequate technical skills and for this reason it is still not widespread and validated. Between October 2010 and March 2012, a consecutive unselected series of eight (N = 8) patients underwent totally laparoscopic splenic flexure resection at our Institute. Data on patients' demographics, disease features, operative details and short-term follow-up were prospectively recorded in a specific database and retrospectively analyzed. All the operations were performed or supervised by the same surgeon (I.S.). We used a four-port medial-to-lateral standardized technique with intracorporeal anastomosis. A selective vascular ligation was performed in all cases and the specimens were extracted through a protected incision. Perioperative care plan and surgical instrumentations were standardized. Complications were classified using the Clavien-Dindo classification system. No conversion to open surgery was registered. All cases achieved an adequate number of lymph nodes harvested (22.9 ± 5.2) and an oncologically correct resection of the tumor (proximal margin 7.0 ± 2.4 cm, distal margin 7.1 ± 2.8 cm). The mean hospital stay was 6.1 ± 1.3 days. Postoperative complication rate according to the Clavien-Dindo system was 37.5 %, but all the complications reported were grade I. We did not observe any reoperation or readmission within 60 days after discharge. Totally laparoscopic splenic flexure resection is a feasible and reproducible technique. A correct surgical indication and a standardized technique allow to perform an oncologically safe and functionally effective treatment.

Totally laparoscopic versus laparoscopic assisted right colectomy for cancer.

INTRODUCTION: Colorectal cancer (CRC) is one of the leading causes of cancer death all over the world and right-sided colon cancer represents approximately 15% of all cases of CRC. Laparoscopic colectomies produce advantages in short-term outcome compared to open procedures and have recently benefited by a long term oncologic validation. This study was designed to compare the short- and medium-term surgical outcomes of totally laparoscopic (TLRC) and laparoscopic-assisted right colectomy (LARC) for neoplasia, hypothesizing they may be at least similar. METHODS: A consecutive unselected series of 72 patients undergone elective surgery for right-sided colon cancer from April 2006 to April 2011 was retrospectively evaluated. All patients were treated by laparoscopic medial-to-lateral right colectomy. In 42 patients a TLRC was performed, in 30 a LARC. Perioperative care plan, operative steps and surgical instrumentations were standardized. All the operations were performed or supervised by the same Surgeon (I.S.). Data on the patients' demographics, disease features, operative details and follow up were recorded and analyzed. Complications were classified using the Clavien-Dindo classification system. Continuous variables were expressed as mean ± standard deviation and analyzed with the Student t test. Categorical ones were expressed as percent value and analyzed with Fischer test or Chi-square test, where appropriate. P < 0.05 were considered statistically significant. RESULTS: There was no significant difference in term of age, sex, body mass index and American Society of Anesthesiology score between the two groups. Comorbidities, site of tumor and stage of disease were similar too. No conversion to laparotomy was registered. Median operative time (186.3 ± 40.1 min vs 176.5 ± 40.0 min; not significant (NS)) and estimated blood loss (43.3 ± 89.8 ml vs 31.2 ± 51.3 ml; NS) were statistically comparable in both groups. Timing of first defecation (3.4 ± 0.9 dd vs 2.9 ± 0.9; P = 0.023) and length of hospital stay (7.2 ± 1.3 dd vs 6.2 ± 1.1 dd; P < 0.001) were statistically lower in TLRC cohort. A significantly longer length of skin incision characterized LARC group compared with TLRC group (71.0 ± 13.5 mm vs 48.2 ± 10.2 mm; P < 0.001). Both groups achieved an adequate number of lymph nodes harvested (22.0 ± 8.2 vs 25.9 ± 9.0; P = 0.036) and oncological resection of the tumor (proximal margin 7.6 ± 7.7 vs 6.1 ± 3.8; NS - distal margin 13.3 ± 7.7 vs 13.6 ± 5.8; NS). Post-operative complications according to Clavien-Dindo classification were statistically comparable in both cohorts. No readmission within 60 days of discharge was observed. The mean follow-up recorded was 27.7 ± 16.6 months. Late complications consisted in 1 case of incisional hernia (3.8%) in LARC group. CONCLUSIONS: Although more appropriate indications must be set by future studies, we encourage the choice of a TLRC for the treatment of cancer of the right colon. TLRC is actually a feasible and safe technique, which has resulted in an encouraging short-term outcome, low incidence of major complications and preservation of oncologic principles, without affecting operative times.

Delayed presentation of splenic injury following diagnostic colonoscopy.

Splenic injury (SI) is a rare complication after colonoscopy, but should be considered in the differential diagnosis of acute abdominal pain following this procedure. We report a case of delayed rupture and review pertinent literature. A 70-year-old patient on oral warfarin intake underwent colonoscopy that diagnosed obstructive rectal cancer and elongated colon conditioning the endoscope's passage. After 48 h, patient experienced sharp abdominal pain with mild peritoneal signs. Contrast-enhanced CT scan evidenced large amount of abdominal-free blood collection from grade II SI. Hypovolemic shock occurred following brief clinical observation. Urgent laparotomic splenectomy and contextual Hartmann's procedure were then carried out. Postoperative course was uneventful and definitive histology confirmed splenic subcapsular haematoma and locally advanced adenocarcinoma. Perforation and bleeding more likely occurred after colonoscopy, while few cases of SI are reported in literature since 1974. Traction on the splenocolic ligament and direct trauma has been advocated as possible causes. Peritoneal adhesions and splenic diseases usually are predisposing factors although not confirmed in our patient. Anticoagulant therapy favoured delayed filling up of subcapsular haematoma while bowel obstruction added further surgical challenge. Rapid onset of hemorrhagic shock required urgent splenectomy that remains the procedure of choice among the literature reviewed.

Outcomes of laparoscopic surgery for colorectal cancer in elderly patients.

OBJECTIVE: To evaluate the short-term outcomes of laparoscopic colorectal surgery for cancer in the elderly compared with younger patients. METHODS: We retrospectively considered a consecutive unselected series of 159 patients who underwent elective laparoscopic procedures for colorectal cancer at our institution between January 2007 and December 2009. Of these patients, 101 (63.5%) were ≤ 70 years of age (Group A), and 58 (36.5%) were >70 (Group B). Operative steps and instrumentation were standardized. Demographics, disease-related, operative, and short-term data were analyzed for each group, and an appropriate statistical comparison was made. Comorbidity was quantified by using the Charlson Comorbidity Index. RESULTS: We reviewed right colectomies (29.5%), left colectomies (44.7%), rectal resections (19.5%), and other procedures (6.3%). There was no significant difference in sex ratio, body mass index, American Society of Anesthesiology score, type of surgical procedures, and tumor stage between Group A and Group B. A statistically higher comorbidity according to the Charlson index characterized Group B (2.2 vs 3.8; P=.034). Median operative time (228 ± 78.1min vs 224.3 ± 97.6min; NS), estimated blood loss (50.0 ± 94.8mL vs 31.2 ± 72.7mL; NS), conversion rate (2.0% vs 1.7%; NS), and timing to canalization (4.5 ± 1.7dd vs 4.4 ± 1.3dd; NS) were statistically comparable in both Groups. Group B was associated with a significantly longer length of hospital stay compared with Group A (8.1 ± 2.8dd vs 10.8 ± 6.6dd; P<.01) There was no statistically significant difference in major postoperative complications (3.8% vs 3.4%; NS), reoperations (0.9% vs 1.7%; NS), and 30-day mortality (0% vs 1.7%; NS). CONCLUSIONS: Laparoscopic colorectal surgery appears feasible and safe in elderly patients with increased comorbidity.

[Successful management of severe unremitting chylothorax after thoraci trauma]. / Trattamento efficace di chilotorace grave e persistente dopo trauma toracico.

Post-traumatic chylothorax needs surgical approach when conservative treatment is not successful to reduce chyle leakage. Thoracic duct ligation requires thoracoscopic or thoracotomic access. The authors report on a surgical thoracotomic approach to a severe and unremitting thoracic duct lesion after IX and X ribs and vertebral fractures.
