Invasive giant pancreatic desmoid-type fibromatosis with curative resection: A case report.

IntroductionDesmoid-type Fibromatoses (DTF) tumours are rare, benign fibrous tumours with aggressive invasive behaviour that account for approximately 0.03% of all neoplasms. We report the success in curing a rare, invasive, and huge pancreatic intraabdominal DTF.Presentation of caseA 42 years old male was medically free apart from recurrent left upper abdominal pain, anorexia, and nausea for more than ten years and no significant past surgeries, trauma, or family history of cancer. The patient has a non-tender large abdominal mass at the left hypochondria area extending down to the pelvis below the umbilicus with a rigid and smooth surface. The computed tomography scan showed a huge heterogeneous mass appears to be of pancreatic origin, measuring about 23 cm by 15 cm by 11 cm. The patient underwent radical antegrade modular pancreato-splenectomy, segmental transverse colectomy, adrenalectomy, and subsequent colo-colic anastomosis. The accurate gross size of the tumour specimen was 26 × 17 × 9 cm, and the weight was found to be 3.6 kg. Immunohistochemistry confirmed the diagnosis of pancreas DTF. The follow up to 5 years confirmed no recurrence reported clinically or by imaging.DiscussionThe Pancreas origin of DTF is a rarely reported subset with an incidence of around 5% of all DTF. Establishing the diagnosis is fundamentally based on the characteristic pathological and immunohistochemical studies, for the only available cure modality by complete radical resection to be promptly offered.ConclusionOur case is rare and uniquely the largest pancreatic DTF reported in the literature with curative resection despite being locally invasive.

Impact of primary tumor resection on the survival of patients with unresectable colon cancer liver metastasis at different colonic subsites: a propensity score matching analysis

Objective To investigate the effect of primary tumor resection (PTR) on the prognosis of patients with unresectable colon cancer liver metastasis (UCCLM) at seven colonic subsites using the Surveillance, Epidemiology, and End Results (SEER) database. Methods Propensity score matching (PSM) was performed to balance selection bias using all available variables that could be of potential relevance. After matching, the groups were redefined in a 1:1 ratio using the nearest method. Cancer-specific survival (CSS) was compared among the patients of PTR and non-PTR groups. Cox regression models were used to identify the prognostic factors for CSS. Results CSS was significantly different between all groups. Cox regression analysis showed that PTR was an independent prognostic factor for all groups. After PSM, PTR significantly prolonged CSS for all groups. Subgroup analysis showed that PTR did not improve the prognosis of N2 stage patients in the cecum, ascending colon, and descending colon groups; T1 + T2 stage patients in the hepatic flexure group; and patients with a tumor size ≤5 cm in the splenic flexure group. Segmental colectomy could prolong CSS of patients in the cecum, ascending colon, transverse colon, splenic flexure, and sigmoid colon groups, while extended colectomy could prolong CSS of patients in the hepatic flexure and descending colon groups. Conclusion At different colonic subsites, UCCLM patients had different CSS. PTR could improve their prognosis, however, N stage, T stage, and tumor size are important reference indicators. In addition to patients in the hepatic flexure and descending colon groups, we suggested that patients in other groups should choose segmental colectomy.

PARCELAR GASTRIC RESECTION IN ASSOCIATION WITH BOWEL RESECTIONS AS PART OF DEBULKING SURGERY FOR ADVANCED STAGE OVARIAN CANCER – A CASE REPORT

Ovarian cancer represents one of the most aggressive gynecological malignancies affecting women worldwide, associated with significant rates of cancer related death within the first years after the initial diagnostic. The poor survival rates are usually explained by the presence of disseminated lesions even from the beginning. In such situations, the digestive tube is one of the most commonly involved territory, therefore necessitating extended resections in order to achieve complete cytoreduction. The aim of this paper is to report the case of a 53 year old patient who was diagnosed with peritoneal carcinomatosis from ovarian cancer, presenting multiple levels of digestive tract involvement due to the presence of disseminated tumoral masses. Therefore the patients was submitted to multiple digestive resections represented by parcelar gastrectomy, segmental ileal resection and subtotal colectomy. In order to minimize the risks of developing severe postoperative complications – due to the relatively high number of anastomoses – the continuity of the digestive tract was established by a terminal ileostomy, considering that creation of a ileorectal anastomosis would be too dangerous in the context of multiple digestive resections. The postoperative evolution was simple, the patient being further submitted to adjuvant treatment.

Single-docking robotic-assisted artery-guided segmental splenic flexure colectomy for splenic flexure cancer—a propensity score-matching analysis

Splenic flexure cancer (SFC) is a rare condition in colorectal cancer (CRC). The appropriate surgical treatment for SFC remains controversial. In recent years, we have used artery-guided segmental splenic flexure colectomy (ASFC) to treat SFC in which robotic access is gradually applied. The study sought to assess the clinical and oncologic outcomes of robotic-assisted ASFC compared to laparoscopic-assisted ASFC for SFC by undertaking a propensity score-matching analysis. Seventy patients underwent a robotic-assisted ASFC (n=19) or laparoscopic-assisted ASFC (n=51) to treat SFC from Dec 2015 to Dec 2019. Their data were prospectively collected. The patients were matched at a ratio of 1:1 according to sex, age, body mass index (BMI), comorbidities, the American Society of Anesthesiologists (ASA) score (≤2 or >2), previous abdominal surgeries, and pathologic stage. No statistically significant differences were found between the robotic- and laparoscopic-assisted ASFC groups in relation to operation time, estimated blood loss, length of postoperative hospital stay, time to liquid diet, postoperative complications, tumor size, distal resection margins, histology, lymph node harvest, metastatic lymph nodes, and neuro-vascular invasion. Additionally, no case was converted to a laparotomy. There were no cases readmission or mortality within 30 days of surgery. The distal resection margins were longer in the robotic-assisted ASFC group than the laparoscopic-assisted ASFC group. The robotic-assisted ASFC group had significantly higher operation expenses than the laparoscopic-assisted ASFC group. However, there was no significant difference in the surgical material expenses between the two groups. There were 2 cases of complications in each group; both cases were classified as grade I or II under Dindo's classification of surgical complications. With the exception of operation expenses, robotic-assisted ASFC rivals laparoscopic-assisted ASFC in many respects. ASFC meets the recommended oncological criteria in terms of resection margins and lymph node harvest. We await the results for the long-term oncologic outcomes.

DOP30 Segmental vs extended colectomy for colorectal cancer in Crohn’s Disease: Results from a multi-centre retrospective comparative study

Abstract Background There is a recognized increased risk for colorectal cancer (CRC) in patients with Crohn’s disease (CD). CD patients with CRC might also show a higher prevalence of synchronous and metachronous cancers. On this basis, current guidelines recommend pan-proctocolectomy (PPC) as a treatment. Aim of this study was to evaluate oncologic outcomes and the actual risk of developing metachronous cancers in CD patients undergoing segmental colectomy (SC) for CRC. Methods All CRC CD patients undergoing surgery in select European and U.S. tertiary referral centres were enrolled. Short and long-term results of SC were compared with those of patients undergoing extended colectomies: total colectomy (TC) and panproctocolectomy (PPC). Primary outcomes were progression-free survival (PFS) and overall survival (OS). Secondary outcomes were postoperative complications, 30 days mortality, re-admission, length of stay, incidence of synchronous and metachronous lesions. Results 91 patients were included: 50 (54%) did not have Crohn’s colitis or had cancer developed in a non-involved segment; cancer developed in inflamed colic segment in 41 (46%). Patients without colitis were more often treated with SC (84%). 62 patients underwent segmental colectomies and 29 extended colectomies (EC): 19 PPC and 10 TC. Patients in the SC group were older (p 0.0429), harboured more metastases at diagnosis (p 0.0219) and were less likely to suffer from CD pancolitis (p 0.0022). Incidence of major complications was comparable in SC (8.6%) vs EC (3.45%) (p 0.06602). There was no perioperative mortality and no difference in specific complications, re-admission or length of stay. 28 patients (30%) suffered disease progression: 22 (35%) after SC and 6 (21%) after EC. Of the 19 cancer related deaths (20%), 16 (25%) were in SC and 3 (10%) in EC groups. There was no difference in unadjusted PFS between SC and EC (0.64 vs 0.79 respectively, Wilcoxon p 0.1029) nor in OS (0.74 vs 0.89, Wilcoxon p 0.1591), after a median follow up of 42 months (55.76 vs 31.13 months respectively). Multivariate analysis confirmed no difference in PFS (HR 1.582, p 0.4964) or OS (HR1 428, p 0.4758). 6 synchronous lesions were found in the 29 patients undergoing EC: 3 low grade dysplasia (10%), 1 high grade dysplasia (3.4%) and 2 preoperatively diagnosed cancers (6.8%). 1 patient (1,61%) developed a metachronous colon cancer of the 62 who had SC and none of the 10 TC. Conclusion CRC in CD is a complex situation and choice of procedure is multifaceted. Incidence of synchronous and metachronous cancers appears much lower than previously described. SC offers similar long-term outcomes to more extensive surgery. Current guidelines for the treatment of CRC in CD patients may need to be reconsidered.

A rare cause of lower gastrointestinal bleeding treated with robotic colorectal surgery

BackgroundMetastatic melanoma to the colon is rarely diagnosed with an incidence of only 0.3% and more than 95% of cases identified post-mortem. Survival for patients with metastatic melanoma to the colon is poor, with 5-year survival rates of 26.5%. Nonetheless, surgical resection of the colonic metastatic melanoma lesions is recommended as it is associated with improved survival. Additionally, surgical resection is also indicated for palliative reasons, as symptom resolution is achieved in 90% of such patients. Use of the surgical robot has increased dramatically in the past decades, especially in the field of colorectal surgery. Furthermore, recent studies have demonstrated comparable outcomes between patients undergoing either laparoscopic or robotic-assisted colorectal surgery for cancer. Here, we describe the first case, to the authors knowledge, of a robot-assisted sigmoid colectomy for metastatic melanoma.Case presentationA 72-year-old male with a history of metastatic melanoma diagnosed in 2015 with a favorable response to immunotherapy presented to the emergency department with symptomatic lower gastrointestinal bleeding (LGIB). Endoscopy demonstrated a friable melanotic lesion of the sigmoid colon with biopsy demonstrating histopathologic evidence of metastatic melanoma. After further evaluation, the patient consented for an elective robot-assisted segmental colectomy for palliative intent. Diagnostic laparoscopy identified no evidence of further intra-abdominal metastatic disease. After identifying the metastatic lesion in the sigmoid colon, the mesentery of involved segment of sigmoid colon adjacent to the lesion was divided using the bipolar electrosurgical vessel sealer device. The colon was divided both proximal and distal to the lesion using a robotic stapler and a tension-free colo-colonic anastomosis was created intracorporeally. Postoperatively, the patient had an unremarkable course and was discharged home on post-operative day 3. On follow-up, the patient was doing well with resolution of preoperative LGIB.Conclusion This case highlights a rare presentation of metastatic melanoma to the colon in a patient presenting with LGIB. Furthermore, this case demonstrates the feasibility of the minimally invasive robotic-assisted approach for an uncommon pathology.

Pancreatic malignancy in the backdrop of chronic pancreatitis: How much to push the boundaries to achieve R0 resection

Abstract Tumors of the body and tail of the pancreas are often more aggressive than tumors of the head and would have often undergone metastatic spread to other organs at the time of diagnosis. Most patients with carcinoma of the body and tail of the pancreas present at a late stage. Surgery is only indicated in those patients in whom there is no evidence of metastatic spread. Surgery is often not possible in cancers of the body and tail of the pancreas if the tumor invades celiac artery. Controversy exists regarding the margin status impact of microscopic resection margin involvement (R1) after pancreaticoduodenectomy (PD) for PDAC. There are reports indicating the rate of R1 resections increases significantly after PD if pathological examination is standardized. In this report, we present the case of a 56-year-old female who had undergone lateral pancreaticojejunostomy for chronic pancreatitis 8 years ago, but has now developed malignancy of the body and tail of the pancreas involving multiple organs. This patient underwent en bloc resection involving: 1. distal pancreatectomy with jejunal loop (lateral pancreaticojejunostomy) resection; 2. splenectomy; 3. left nephrectomy; 4. total gastrectomy; and 5. segmental colectomy with reconstruction by esophagojejunostomy, jejunojejunostomy, and colocolic anastomosis. The infrequent occurrence of tumor in the distal gland and advanced tumor stage at the time of diagnosis have both combined to produce therapeutic nihilism/dilemma in the minds of many surgeons. This report highlights the decision on how much to the push limits for multi-organ resection (en bloc resection with distal pancreatectomy, gastrectomy, splenectomy, colectomy, nephrectomy) with the intent of achieving R0 status in spite of the complexity of surgery in selected patients.

Emergency surgery for splenic flexure cancer: results of the SFC Study Group database

BackgroundThe effectiveness of surgical treatment for splenic flexure carcinomas (SFCs) in emergency settings remains unexplored. This study aims to compare the perioperative and long-term outcomes of different alternatives for emergency SFC resection.MethodThis multicenter retrospective study was based on the SFC Study Group database. For the present analysis, SFC patients were selected if they had received emergency surgical resection with curative intent between 2000 and 2018. Extended right colectomy (ERC), left colectomy (LC), and segmental left colectomy (SLC) were evaluated and compared.ResultsThe study sample was composed of 90 SFC patients who underwent emergency ERC (n = 55, 61.1%), LC (n = 18, 20%), or SLC (n = 17, 18.9%). Bowel obstruction was the most frequent indication for surgery (n = 75, 83.3%), and an open approach was chosen in 81.1% of the patients. A higher incidence of postoperative complications was observed in the ERC group (70.9%) than in the LC (44.4%) and SLC groups (47.1%), with a significant procedure-related difference for severe postoperative complications (Dindo-Clavien ≥ III; adjusted odds ratio for ERC vs. LC:7.23; 95% CI 1.51-34.66; p = 0.013). Anastomotic leakage occurred in 8 (11.2%) patients, with no differences between the groups (p = 0.902). R0 resection was achieved in 98.9% of the procedures, and ≥ 12 lymph nodes were retrieved in 92.2% of patients. Overall and disease-free survival rates at 5 years were similar between the groups and were significantly associated with stage pT4 and the presence of synchronous metastases.ConclusionIn the emergency setting, ERC and open surgery are the most frequently performed procedures. ERC is associated with increased odds of severe postoperative complications when compared to more conservative SFC resections. Nonetheless, all the alternatives seem to provide similar pathologic and long-term outcomes, supporting the oncological safety of more conservative resections for emergency SFCs.

"Unresectable" polyp management utilizing advanced endoscopic techniques results in high rate of colon preservation.

"Endoscopically unresectable" benign polyps identified during screening colonoscopy are often referred for segmental colectomy. Application of advanced endoscopic techniques can increase endoscopic polyp resection, sparing patients the morbidity of colectomy. This retrospective case-control study aimed to evaluate the success of colon preserving resection of "endoscopically unresectable" benign polyps using advanced endoscopic techniques including endoscopic mucosal resection, endoscopic submucosal dissection, endoluminal surgical intervention, full-thickness laparo-endoscopic excision, and combined endo-laparoscopic resection. A prospectively maintained institutional database identified 95 patients referred for "endoscopically unresectable" benign polyps from 2015 to 2018. Cases were compared to 190 propensity score matched controls from the same database undergoing elective laparoscopic colectomy for other reasons. Primary outcome was rate of complete endoscopic polyp removal. Secondary outcomes included length of stay, unplanned 30-day readmission and reoperation, 30-day mortality, and post-procedural complications. Advanced endoscopic techniques achieved complete polyp removal without colectomy in 66 patients (70%). Failure was most commonly associated with previously attempted endoscopic resection and occult malignancy. Compared with matched colectomy controls, endoscopic polyp resection resulted in significantly shorter hospital length of stay (1.13 ± 2.41 vs 3.89 ± 4.57days; p < 0.001), lower unplanned 30-day readmission (1.1% vs 7.7%; p < 0.05), and fewer postoperative complications (4.2% vs 33.9%; p < 0.001). Unplanned 30-day reoperation (2.1% vs 4.4%; p = 0.34) and 30-day mortality (0% vs 0.6%; p = 0.75) trended lower. Endoscopic resection of complex polyps can be highly successful, and it is associated with favorable outcomes and decreased morbidity when compared with segmental colon resection. Attempting colon preservation using these techniques is warranted.

Self-Expandable Metal Stents for Left Sided Colon Obstruction from Diverticulitis. A Single Center Retrospective Series.

Background and Objectives: The incidence of diverticulitis is increasing in western countries. Complicated diverticulitis is defined as diverticulitis associated with localized or generalized perforation, localized or distant abscess, fistula, stricture or obstruction. Colonic symptomatic strictures are often treated with segmental colectomy. The aim of our study is to report our experience with Self Expandable Metal Stents (SEMS) placement to relieve sigmoid obstruction secondary to diverticulitis, either as a permanent solution or as a bridge to elective colectomy. Material and Methods: From January 2016 to December 2018, 21 patients underwent SEMS placement for sigmoid obstruction secondary to diverticulitis at our institution. In four patients with poor general conditions, SEMS was considered the definitive form of treatment. In 17 patients, the stent was placed as bridge to elective colectomy. Data were prospectively collected and retrospectively analyzed. Primary outcomes were postoperative mortality and morbidity after SEMS and subsequent elective colectomy. Results: There was no mortality or major morbidity after SEMS placement or subsequent elective colectomy. No stoma was performed. Conclusions: Placement of Colorectal Self Expandable Stent represents a useful tool to relieve obstruction in patients with left-sided colonic diverticulitis. SEMS placement makes it possible to transform an emergency clinical condition into an elective condition, giving time to resolve the inflammation and the infection inevitably associated with complicated diverticulitis.

Role for colorectal teams to support non-colorectal teams to improve clinical outcomes and adherence to ERAS guidelines for segmental colectomy: a cohort study

BackgroundTo identify whether compliance with Enhanced Recovery After Surgery (ERAS) Society recommendations is associated with length of stay (LOS) in a New Zealand hospital for patients undergoing segmental colectomy in mixed acute and elective general surgery wards.MethodsConsecutive elective colorectal surgeries (n = 770) between October 2012 and February 2019 were audited. Patients with non-segmental colectomies, multi-organ surgeries, LOS > 14 days, and those who died were excluded. Logistic regression was used to determine the relationship between patient demographics, compliance with ERAS guidelines, and suboptimal LOS (> 4 days).ResultsAnalysis included 376 patients. Age, surgery prior to 2014, surgical approach, non-colorectal surgical team, operation type, and complications were significantly associated with suboptimal LOS. Non-compliance with ERAS recommendations for laparoscopy [OR 8.9, 95% CI (4.52, 19.67)], removal of indwelling catheters (IDC) [OR 3.14, 95% CI (1.85, 5.51)], use of abdominal drains [OR 4.27, 95% CI (0.99, 18.35)], and removal of PCA [OR 8.71, 95% CI (1.78, 157.27)], were associated with suboptimal LOS (univariable analysis). Multivariable analysis showed that age, surgical team, late removal of IDC, and open approach were independent predictors of suboptimal LOS.ConclusionsNon-compliance with ERAS guidelines for laparoscopic approach and early removal of IDC was higher among procedures performed by non-colorectal surgery teams, and was also associated with adverse postoperative events and suboptimal LOS. This study demonstrates the importance of the surgical team’s expertise in affecting surgical outcomes, and did not find significant independent associations between most individual ERAS guidelines and suboptimal LOS once adjusting for other factors.

Update on the management of sigmoid diverticulitis

Diverticular disease and diverticulitis are the most common non-cancerous pathology of the colon. It has traditionally been considered a disease of the elderly and associated with cultural and dietary habits. There has been a growing evolution in our understanding and the treatment guidelines for this disease. To provide an updated review of the epidemiology, pathogenesis, classification and highlight changes in the medical and surgical management of diverticulitis. Diverticulitis is increasingly being seen in young patients (< 50 years). Genetic contributions to diverticulitis may be larger than previously thought. Potential similarities and overlap with inflammatory bowel disease and irritable bowel syndrome exist. Computed tomography imaging represents the standard to classify the severity of diverticulitis. Modifications to the traditional Hinchey classification might serve to better delineate mild and intermediate forms as well as better classify chronic presentations of diverticulitis. Non-operative management is primarily based on antibiotics and supportive measures, but antibiotics may be omitted in mild cases. Interval colonoscopy remains advisable after an acute attack, particularly after a complicated form. Acute surgery is needed for the most severe as well as refractory cases, whereas elective resections are individualized and should be considered for chronic, smoldering, or recurrent forms and respective complications (stricture, fistula, etc.) and for patients with factors highly predictive of recurrent attacks. Diverticulitis is no longer a disease of the elderly. Our evolving understanding of diverticulitis as a clinical entity has led into a more nuanced approach in both the medical and surgical management of this common disease. Non-surgical management remains the appropriate treatment for greater than 70% of patients. In individuals with non-relenting, persistent, or recurrent symptoms and those with complicated disease and sequelae, a segmental colectomy remains the most effective surgical treatment in the acute, chronic, or elective-prophylactic setting.

CLINICAL AND PATHOLOGICAL FEATURES OF COLONIC ILEUS FROM OBSTRUCTIVE COLORECTAL CANCER. ACTUAL CHARACTERISTICS

Purpose: The purpose of this study is to analyze the possible change in the characteristics of patients with colonic ileus from obstructive colorectal cancer in UMHATEM "N. Pirogov ". Material and Methods: For two separate periods of 2 years in the Department of General, Visceral and Emergency Surgery in University Hospital "N. I. Pirogov" from ileus caused by colorectal carcinoma were operated respectively: Group A (1.1.2010-31.12.2011) - 187 patients (average 71.2 years, women were 88, men 99) Group B (1.1.2014-31.12.2015) - 141 patients (average 73.5 years, women were 69, men 72). Results: In group B there was an increase in the infected patients at an earlier stage. There was no significant difference in the localization of the tumor process in the two groups. In contrast to the increased number of patients hospitalized at an earlier ileus stage, there was no difference in the two groups according to the tumor stage. Conclusions: Emergency surgery is indicated for cases with full bowel obstruction and significant prediction of rupture. Surgery procedure like proximal colostomy is reccomended for elderly patients and complicated comorbidity. Primary procedure like segmental and subtotal colectomy is appropriate for patients in good condition. Segmental resection is favorable in elderly patients and those with shock who may not tolerate lengthy surgery.

Bowel function recovery after laparoscopic transverse colectomy within an ERAS program: a comparison to right and left colectomy

It is known that functional recovery of the bowel is slower after right colectomy (RC) compared to left colectomy (LC), but very little has been reported on transverse colectomy (TC). The aim of this study was to compare the clinical and early functional outcomes of TC, a more infrequent operation, to RC, and LC for colorectal cancer. Between December 2011 and December 2017, all patients undergoing elective colon resection in our institution were treated according to a standardized ERAS protocol and entered in a prospective database. We included in the study patients undergoing laparoscopic TC, RC, or LC for cancer with curative intent. The primary endpoint was prolonged postoperative ileus (PPOI), defined as need to insert a nasogastric tube, or refractory nausea VAS > 4 on or after the third postoperative day. Secondary endpoints were postoperative morbidity and length of hospital stay (LoS). Out of 286 patients, 126 met the inclusion criteria: 20 underwent TC, 65 RC, and 41 LC. Patients in LC group were younger than in TC and RC groups; other baseline demographics were similar. PPOI was observed in 5 (25%), 26 (40%), and 10 (24%) patients in TC, RC, and LC groups, respectively (p= 0.417). In single group comparisons, the incidence of PPOI in the TC group was significantly lower in comparison to the RC group (OR for RC: 4.255, 95% CI 1.092-16.667, p= 0.037) and similar to the LC group. No significant differences in terms of postoperative complications or LoS stay were observed. The incidence of PPOI after segmental laparoscopic colectomy for cancer within an ERAS program appears as infrequent in TC as in LC and lower than after RC. It may be reasonable to consider a slower oral intake after RC, as it represents an independent predictor of PPOI.

Combined endoscopic-laparoscopic surgery (CELS) can avoid segmental colectomy in endoscopically unremovable colonic polyps: a cohort study over 10 years.

Combined-Endoscopic-Laparoscopic-Surgery (CELS) was developed for benign colonic polyps, endoscopically unresectable, to avoid segmental colectomy. This observational study aims to compare surgical outcomes of endoscopically unresectable colonic polyps treated laparoscopically before and since the institutional introduction of CELS. Primary endpoint was postoperative morbidity and mortality; secondary endpoints were time of hospitalization and histopathological findings. Charts of all patients with preoperative diagnosis of benign colonic tumors, treated laparoscopically at our institution from 1/2010 to 2/2020 were reviewed. Patients with polyps (1) affecting ileocecal valve, (2) occupying > 50% of the circumference, (3) ≥ 3 endoscopically unresectable polyps, (4) inflammatory bowel disease, (5) polyps within diverticular area post diverticulitis, (6) rectal polyps (7) foreseen impossibility of laparoscopy (8) preoperatively biopsy proven invasive adenocarcinoma were excluded. Group I consists of all patients potentially treatable by CELS but operated by laparoscopic colonic resection as CELS was not yet institutionally established. Group II includes all patients treated with CELS (since 11/2017). One hundred-fifteen consecutive patients were reviewed. Applying exclusion criteria, twenty-three patients form group I and twenty-three group II (female 30.4%, median age 68 years). Groups distributed homogenously for age, BMI (body mass index) and polyps´ localization with most polyps (60.4%) localized in right colon; group II patients had significantly higher American Society of Anesthesiologists (ASA) score. Median operating time, hospital stay and morbidity were significantly less in group II. Postoperative morbidity occurred overall in 14 patients (30.4%), mostly Clavien-Dindo class I-II (26.1%) and significantly less in group II (p = 0.017), Clavien-Dindo III-IV distributed equally (one patient each group) without postoperative mortality. Definitive histopathology showed invasive adenocarcinoma in 8.3% without differences between groups. Two patients with invasive adenocarcinoma after CELS were advised for oncological resection. CELS is safe and efficient to treat complex, benign colonic polyps by a complete minimal invasive laparoscopic approach. CELS showed better surgical outcomes with less morbidity, no mortality and appropriate pathological results avoiding unnecessary laparoscopic surgery with intestinal anastomosis.

Long-Term Functional Results of a Modified Caudal-to-Cranial Approach in Laparoscopic Segmental Left Colectomy for Diverticular Disease.

A modified caudal-to-cranial approach to perform laparoscopic left colectomy for benign diseases has been recently designed to facilitate the low-tie mesenteric dissection. A chart review has been performed including all consecutive patients with uncomplicated diverticulitis who have been treated by segmental left colectomy with a caudal-to-cranial approach. A total of 34 patients were included in the study. 21 patients were male, mean age was 54.1 ± 11.3, and mean BMI was 26 ± 5.5. Patients with ASA Score I were 7, with ASA II were 9, and with ASA Score III were 5. Incontinence Score (IS) resulted in an average of 5 ± 2, 2 grade of incontinence and the CS score showed an average of 10 ± 3, 2 grade of constipation. Health status, evaluated by Short Form-36 questionnaire, was demonstrated in these patients' great physical function, role, general health, and social function. The anorectal manometry performed 6 months after surgery showed a normal value in terms of the anal resting pressure (47 ± 13 mmHg) and an increased volume to stimulate desire to defecate (197 ± 25 ml). The length of the anal sphincter was normal compared to the reference value (37 ± 5.4 mm). Although further studies are required to obtain definitive conclusions, our results are encouraging to propose low-tie segmental colectomy as the standard procedure for the treatment of uncomplicated diverticulitis, and our modified surgical approach could be considered useful to facilitate the surgical approach.

Short- and long-term outcomes of laparoscopic segmental left colectomy for splenic flexure colon cancer: comparison with propensity score matching.

PurposeSplenic flexure colon cancer (SFCC) is a rare disease that accounts for 2%–8% of colorectal cancers, and the extent of surgery and resection is still debatable. There have also been few studies on the safety and feasibility of laparoscopic surgery for SFCC. The purpose of this study is to evaluate outcomes and prognoses of surgery for SFCC.MethodsWe included patients with stage 1 to 3 who had undergone laparoscopic surgery for distal transverse-to-sigmoid colon cancer at 2 hospitals from March 2004 to December 2016 and collected data by retrospective design. We defined SFCC as being cancer between distal transverse and proximal descending colon. The short- and long-term outcomes of the anterior resection (AR) group (those patients who had undergone laparoscopic AR for mid and distal descending to sigmoid colon cancer) and the left colon resection (LR) group (those who had undergone laparoscopic segmental left colectomy for SFCC) were compared using propensity score matching.ResultsThe median follow-up period was 60 months. The numbers of subjects in the AR and the LR groups were 948 and 118. After 2:1 propensity score matching, 236 vs. 118 patients were selected. There was no significant difference in 5-year disease-free survival (80.7% vs. 78.6%, P = 0.607), and both the 5-year overall survival (89.2% vs. 88.2%, P = 0.563) as well as short-term outcomes showed no statistical difference in most of the variables.ConclusionLaparoscopic segmental left colectomy can be one option among the standard procedures for SFCC.

Robotic left colectomy with double indocyanine green guidance and intracorporeal anastomoses.

Radical surgery is the mainstay of treatment of colon cancer. Lymphatic drainage of splenic flexure colon cancer is variable, and the exact site of lymphatic dissection is uncertain. Hence, a true consensus of what kind of colectomy should be performed for tumours of the splenic flexure is lacking. Segmental left colectomy (splenic flexure colectomy) (extended), left colectomy as well as subtotal colectomy (extended right colectomy) all have their proponents. Robotic colectomy addresses the limitations of straight laparoscopic colon resections. We report our technique of single-docking totally robotic left hemicolectomy for splenic flexure adenocarcinoma using Da Vinci Xi® Surgical System (Intuitive Surgical, USA) with indocyanine green near-infrared fluorescence for the assessment of both the lymph nodes and intestinal blood flow in real time.

Surgical treatment of colonic Crohn\u2019s disease: a national snapshot study

AimThe different surgical options for patients with colonic Crohn’s disease (CD) include segmental colectomy, subtotal colectomy or proctocolectomy with end ileostomy. We present a national, multicentre study, promoted by the Italian Society of Colorectal Surgery with the aim to collect benchmark data and national variations on multidisciplinary management and postoperative outcomes of patients undergoing surgery for colonic CD.MethodsAll adult patients having elective surgery for colonic CD from June 2018 to May 2019 were eligible for participation in this retrospective study. The primary outcome measure was postoperative morbidity within 30 days of surgery.ResultsOne hundred twenty-two patients were included: 55 subtotal colectomy, 30 segmental colectomy, 25 proctectomy and 12 proctocolectomy. Eighty-six patients (70.4%) were discussed at the inflammatory bowel disease (IBD) multidisciplinary team meeting (MDT) prior to surgery. This ranged from 76.6% for segmental colectomy to 60% for subtotal colectomy, 66.6% for proctocolectomy and 48% for proctectomy. The proportion of patients counselled by a stoma nurse preoperatively was 50%. Laparoscopy was associated with reduced postoperative morbidity (p = 0.017) and shorter length of hospital stay (p < 0.001), whilst pre-operative anti-TNF was associated with Dindo-Clavien ≥ 3 complications (p = 0.023) and longer in-hospital stay (p = 0.007). The main procedure performed (segmental colectomy, subtotal colectomy, proctocolectomy or proctectomy) was not associated with postoperative morbidity (p = 0.626).ConclusionsSurgery for colonic CD has a high rate of postoperative complications. Almost a third of the patients were not preoperatively discussed at the IBD MDT, whilst the use of minimally invasive surgery for surgical treatment of colonic CD ranges from 40 to 66%.
