After Elective Sigmoid Colectomy for Diverticulitis, Does Recurrence-Free Mean Symptom-Free?

After elective sigmoidectomy for diverticulitis, patients may experience persistent abdominal symptoms. This study aimed to determine the incidence and characteristics of persistent symptoms (PSs) and their risk factors in patients who had no reported recurrence after elective sigmoidectomy. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included. After retrospective review of medical records, patients were contacted with a questionnaire to inquire about recurrence of diverticulitis and persistent abdominal symptoms since resection. Outcomes examined were prevalence of and risk factors for PSs after elective sigmoidectomy. Of 662 included patients, 346 completed the questionnaire and had no recurrent diverticulitis. PSs were reported by 43.9 per cent of the patients. The mean follow-up was 87 months. Female gender and preoperative diagnosis of irritable bowel syndrome were independent risk factors for PSs (Relative Risk 1.65, P < 0.001 and Relative Risk 1.41, P = 0.014). Previous IV antibiotics treatment was associated with PSs (P = 0.034) but not with a significant risk factor. As the follow-up interval increased, prevalence of PSs decreased (P = 0.006). More than 40 per cent of patients experienced persistent abdominal symptoms after sigmoidectomy for diverticulitis. Female patients and those with irritable bowel syndrome were at significantly increased risk.

Reliability of AXIS Classification System for Prediction of Sigmoid Volvulus Severity

This study aimed at evaluating reliability of AXIS classification system in predicting severity of sigmoid volvulus. This retrospective study included 60 patients diagnosed as sigmoid volvulus in Minia University Hospital, Egypt, from January 2014 to January 2019. According to abdominal X-ray coffee-bean sign mesenteric axis, patients were classified into three groups: group 1, mesenteric axis of 0–90°; group 2, 90–135°; group 3, > 135° from horizontal. Treatment options included endoscopic detorsion followed by elective sigmoidectomy for patients without severe abdominal pain or intestinal necrosis; otherwise, open sigmoidectomy was performed. Analyzed patients’ data included: age, sex, body mass index (BMI), American Society of Anesthesiologists physical status (ASA) score, intestinal necrosis, need for surgery, 30 days mortality, and hospital stay. Sixty patients included 38 for group 1, 20 for group 2, and 2 patients for group 3. Mean age was 71.2 years. Forty-six patients were males, and 14 patients were females. ASA score was ≥ 2 in 56 patients (93.3%). Forty-eight patients (80%) underwent endoscopic detorsion only. Four patients (6.7%) underwent endoscopic detorsion followed by elective sigmoidectomy with primary anastomosis. Eight patients (13.3%) underwent sigmoidectomy and Hartmann’s procedure without endoscopic intervention. Two patients (3.3%) had complications. Intestinal necrosis and need for surgery were significantly associated with AXIS classification. AXIS classification can be used as predictive factor for severity of sigmoid vovulus in early stage of patient’s assessment. However, further prospective studies with large population number are needed to validate this system.

Bowel Function/QoL After Elective Sigmoidectomy vs. Conservative Management for Recurrent Uncomplicated Diverticulitis

Bowel Function/QoL After Elective Sigmoidectomy vs. Conservative Management for Recurrent Uncomplicated Diverticulitis

Safety and feasibility of laparoscopic sigmoid resection without diversion in perforated diverticulitis

Laparoscopic primary anastomosis (PA) without diversion for diverticulitis has historically been confined to the elective setting. Hartmann's procedure is associated with high morbidity rates that might be reduced with less invasive and one-step approaches. The aim of this study was to analyze the results of laparoscopic PA without diversion in Hinchey III perforated diverticulitis. We performed a retrospective analysis of a prospectively collected database of all patients who underwent laparoscopic sigmoidectomy for diverticular disease during the period 2000-2018. The sample was divided in two groups: elective laparoscopic sigmoid resection for recurrent diverticulitis (G1) and emergent laparoscopic sigmoidectomy for Hinchey III diverticulitis (G2). Demographics, operative variables, and postoperative outcomes were compared between groups. A total of 415 patients underwent laparoscopic sigmoid resection for diverticular disease. PA without diversion was performed in 351 patients; 278 (79.2%) belonged to G1 (recurrent diverticulitis) and 73 (20.8%) to G2 (perforated diverticulitis). Median age, gender, and BMI score were similar in both groups. Patients with ASA III score were more frequent in G2 (p: 0.02). Conversion rate (G1: 4% vs. G2: 18%, p < 0.001), operative time (G1: 157min vs. G2: 183min, p < 0.001), and median length of hospital stay (G1: 3days vs. G2: 5days, p < 0.001) were significantly higher in G2. Overall postoperative morbidity (G1: 22.3% vs. G2: 28.7%, p = 0.27) and anastomotic leak rate (G1: 5.7% vs. G2: 5.4%, p = 0.92) were similar between groups. There was no mortality in G1 and one patient (1.3%) died in G2 (p = 0.21). Laparoscopic sigmoid resection without diversion is feasible and safe in patients with perforated diverticulitis. In centers with vast experience in laparoscopic colorectal surgery, patients undergoing this procedure have similar morbidity and mortality to those undergoing elective sigmoidectomy.

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.

Incidence, associated risk factors, and impact of conversion to laparotomy in elective minimally invasive sigmoidectomy for diverticular disease.

Benefits of minimally invasive surgical approaches to diverticular disease are limited by conversion to open surgery. A comprehensive analysis that includes risk factors for conversion may improve patient outcomes. The US Premier Healthcare Database was used to identify patients undergoing primary elective sigmoidectomy for diverticular disease between 2013 and September 2015. Propensity-score matching was used to compare conversion rates for laparoscopic and robotic-assisted sigmoidectomy. Patient, clinical, hospital, and surgeon characteristics associated with conversion were analyzed using multivariable logistic regression, providing odds ratios for comparative risks. Clinical and economic impacts were assessed comparing surgical outcomes in minimally invasive converted, completed, and open cases. The study population included 13,240 sigmoidectomy patients (8076 laparoscopic, 1301 robotic-assisted, 3863 open). Analysis of propensity-score-matched patients showed higher conversion rates in laparoscopic (13.6%) versus robotic-assisted (8.3%) surgeries (p < 0.001). Greater risk of conversion was associated with patients who were Black compared with Caucasian, were Medicaid-insured versus Commercially insured, had a Charlson Comorbidity Index ≥ 2 versus 0, were obese, had concomitant colon resection, had peritoneal abscess or fistula, or had lysis of adhesions. Significantly lower risk of conversion was associated with robotic-assisted sigmoidectomy (versus laparoscopic, OR 0.58), hand-assisted surgery, higher surgeon volume, and surgeons who were colorectal specialties. Converted cases had longer operating room time, length of stay, and more postoperative complications compared with minimally invasive completed and open cases. Readmission and blood transfusion rates were higher in converted compared with minimally invasive completed cases, and similar to open surgeries. Differences in inflation-adjusted total ($4971), direct ($2760), and overhead ($2212) costs were significantly higher for converted compared with minimally invasive completed cases. Conversion from minimally invasive to open sigmoidectomy for diverticular disease results in additional morbidity and healthcare costs. Consideration of modifiable risk factors for conversion may attenuate adverse associated outcomes.

Effect of Elective Sigmoidectomy for Diverticulitis on Bowel Function Patient-Reported Outcomes

IntroductionDiverticular disease is common worldwide. A subset of these patients will choose to undergo elective surgical resection because of symptoms or complicated disease. The aim of this study was to evaluate changes in bowel function after elective sigmoid resection for diverticular disease. Materials and methodsWe retrospectively reviewed patients seen at our institution from May 2015 to July 2018 who underwent elective sigmoid resection for diverticular disease. We used the Colorectal Functional Outcome (COREFO) questionnaire, a validated questionnaire that assesses bowel function in five domains and a global function score (scores 0-100, with higher score indicating worse function). We obtained questionnaire data at baseline, as well as at postoperative follow-up, and a paired t-test was used to compare. ResultsForty-nine patients met criteria for inclusion in this study. The median time between questionnaire completion was 70 days (interquartile range: 56 to 85). The mean age was 60 ± 12 years, with 57% female patients. Thirty-six (73%) patients underwent sigmoidectomy alone and 13 (27%) underwent sigmoidectomy with fistula repair. Six patients (12%) had a diverting loop ileostomy in addition to sigmoidectomy and underwent a subsequent reversal. Overall, there were no differences in any of the five domains or the total Colorectal Functional Outcome score from baseline to postintervention. ConclusionsIn our cohort, bowel function did not significantly change in the early postoperative period after elective sigmoid resection for diverticular disease. Surgeons should counsel patients, especially symptomatic ones, that bowel function will likely be no different at time of postoperative follow-up.

Elective Laparoscopic Sigmoid Colectomy for Diverticulitis—an Updated Look at Recurrence After Surgery

BackgroundSurgical management of diverticulitis is evolving and the decision to offer elective sigmoidectomy for diverticulitis has become more individualized. However, preoperative variables that may predict recurrent diverticulitis after resection and guide surgical decision-making were not well studied. MethodsThis was a retrospective chart review with a prospective questionnaire follow-up of patients. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included and their medical records reviewed. They were then contacted with a questionnaire to inquire about recurrence of diverticulitis since resection. The primary outcome was rate of recurrent diverticulitis after elective sigmoidectomy. The secondary outcome was risk factors for recurrence after sigmoidectomy. ResultsOf 662 patients who underwent elective sigmoidectomy for diverticulitis, 361 had long-term follow-up data available. Mean follow-up was 86 months. Indication for surgery was uncomplicated recurrent diverticulitis in 50%. Recurrent diverticulitis developed in 15 (4.2%) patients. Mean time to recurrence was 55 (range, 6–109) months. All recurrences were confirmed by CT scan. Univariate analysis showed that preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was significantly more prevalent in patients who experienced recurrent diverticulitis after sigmoidectomy (p = 0.049 and p = 0.02); however, these variables did not predict recurrence after resection. ConclusionsOverall rate of recurrent diverticulitis after elective sigmoidectomy was 4.2%. Preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was associated with but not significant predictor of recurrence after elective resection.

Propensity-Matched Analysis of Sigmoidectomies for Diverticular Disease.

Background and Objectives:The role for the robotic-assisted approach as a minimally invasive alternative to open colorectal surgery is in the evaluation phase. While the benefits of minimally invasive colorectal surgery when compared to the open approach have been clearly demonstrated, the adoption of laparoscopy has been limited. The purpose of this study was to evaluate clinical outcomes, hospital and payer characteristics of patients undergoing robotic-assisted, laparoscopic, and open elective sigmoidectomy for diverticular disease in the United States.Methods:This is a retrospective propensity score–matched analysis. The Premier Healthcare Database was queried for patients with diverticular disease. Patients with diverticular disease who underwent robotic-assisted, laparoscopic, and open sigmoidectomy for diverticular disease from January 2013 through September 2015 were included. Propensity-score matching (1:1) facilitated comparison of robotic-assisted versus open approach and robotic-assisted versus laparoscopic approach. Peri-operative outcomes were assessed for both comparisons.Results:There were several outcomes advantages for the robotic-assisted approach when compared to laparoscopic and open sigmoidectomy for diverticular disease that included significantly fewer conversions to open (P = .0002), shorter hospital length of stay, fewer postoperative complications—ileus, wound complications, and acute renal failure—and more patients discharged directly to home.Conclusions:The robotic-assisted minimally invasive approach to elective sigmoidectomy for diverticular disease results in favorable intra-operative and postoperative outcomes when compared to laparoscopic and open approaches.

Outcomes of first-line endoscopic management for patients with sigmoid volvulus

BackgroundSigmoid volvulus is a common cause of colonic obstruction in old and frail patients. Its standard management includes the endoscopic detorsion of the colonic loop, followed by an elective sigmoidectomy to prevent recurrence. However, these patients are often poor candidates for surgery. AimThe aim of this study was to compare death rate between elective sigmoidectomy and conservative management following endoscopic detorsion for sigmoid volvulus. MethodsThe medical records of 83 patients undergoing endoscopic detorsion of a sigmoid volvulus from 2008 to 2014 were retrospectively reviewed. Patients were divided into two groups: ‘elective surgery’ and ‘no surgery’. ResultsPatients in the ‘no surgery’ group (n = 42) were older and had more loss of autonomy than in the ‘elective surgery’ group. Volvulus endoscopic detorsion was successful in 96% of patients with no complications. The median follow-up was 13 months (1 day-67 months). The death rate was 62% in the ‘no surgery’ group versus 32% in the ‘elective surgery’ group (p = 0.02). In the ‘no surgery’ group, 23/42 of patients had volvulus recurrence. No recurrence occurred after surgery. ConclusionElective surgery must be planned as soon as possible after the first episode of sigmoid volvulus. In frail patients, other options must be developed.

Colonoscopy-induced acute diverticulitis: myth or reality?

Colonoscopy in patients with diverticulosis can be technically challenging and limited data exist relating to the risk of post-colonoscopy diverticulitis. Our aim was to evaluate the incidence, management, and outcomes of acute diverticulitis following colonoscopy. Study design is retrospective cohort study. Data were gathered by conducting an automated search of the electronic patient database using current procedural terminology and ICD-9 codes. Patients who underwent a colonoscopy from 2003 to 2012 were reviewed to find patients who developed acute diverticulitis within 30 days after colonoscopy. Patient demographics and colonoscopy-related outcomes were documented, which include interval between colonoscopy and diverticulitis, colonoscopy indication, simultaneous colonoscopic interventions,and follow-up after colonoscopy. From 236,377 colonoscopies performed during the study period, 68 patients (mean age 56years) developed post-colonoscopy diverticulitis (0.029%; 2.9 per 10,000 colonoscopies). Incomplete colonoscopies were more frequent among patients with a history of previous diverticulitis [n = 10 (29%) vs. n = 3 (9%), p = 0.03]. Mean time to develop diverticulitis after colonoscopy was 12 ± 8 days, and 30 (44%) patients required hospitalization. 34 (50%) patients had a history of diverticulitis prior to colonoscopy. Among those patients, 14 underwent colonoscopy with an indication of surveillance for previous disease. When colonoscopy was performed within 6weeks of a diverticulitisattack, surgical intervention was required more often when compared with colonoscopies performed after 6weeks of an acute attack [n = 6 (100%) vs. n = 10 (36%), p = 0.006]. 6 (9%) out of 68 patients receivedemergency surgical treatment. 15 (24%) out of 62 patients who had non-surgical treatment initially underwent an elective sigmoidectomy at a later date. Recurrent diverticulitis developed in 16 (23%) patients after post-colonoscopy diverticulitis. Post-colonoscopy diverticulitis is a rare, but potentially serious complication. Although a rare entity, possibility of this complication should be kept in mind in patients presenting with symptoms after colonoscopy.

Long-term outcomes of sigmoid diverticulitis: a single-center experience

BackgroundDuring the last decade, guidelines for the treatment of sigmoid diverticulitis have dramatically changed. The aim of this study is to report the long-term outcomes of patients treated for diverticulitis at a nonspecialized single center. Materials and methodsAfter obtaining institutional review board approval, medical records of all patients admitted to our institution with the diagnosis of sigmoid diverticulitis between 1998 and 2008 were reviewed. A follow-up of at least 5 years was required. ResultsDuring the study period, 266 patients were admitted to our hospital due to sigmoid diverticulitis with a mean follow-up period of 120 ± 2 months. Of the entire cohort, 249 patients (93.5%) were treated conservatively and 17 (6.5%) patients required emergent surgery on initial presentation. Patients treated conservatively (n = 249) encountered a median of two recurrent episodes (range 0-4). During follow-up, none of these patients required emergent surgery, and 27 patients (11%) underwent elective surgery for recurrent episodes (n = 24), chronic smoldering disease (n = 2), and fistula (n = 1). Minor and major complication rates after elective surgery were 18.5% and 30%, respectively. Specifically, four patients (15%) suffered an anastomotic leak (AL). Late complications after elective surgery occurred in 33% of patients including incisional hernias (11%), bowel obstruction (3.7%), anastomotic stenosis (3.7%), and recurrent diverticulitis (15%). ConclusionsPatients treated conservatively during their index admission for sigmoid diverticulitis do not require emergent surgery during long-term follow-up and the majority of patients (89%) do not require elective surgery. Elective sigmoidectomy at nonspecialized centers may result in high rates of recurrent diverticulitis (15%) and anastomotic leak (15%).

Are there differences in outcome after elective sigmoidectomy for diverticular disease and for cancer? A national inpatient study.

The postoperative outcome after elective sigmoidectomy for diverticulitis has not been compared to that for cancer. The study aimed to evaluate the differences in the postoperative outcome after sigmoidectomy for diverticular disease and cancer. The National Inpatient Sample Database was used to identify patients who underwent elective sigmoid resection for diverticular disease or cancer between 2004 and 2011. After excluding patients with metastatic cancer and preoperative weight loss, sigmoid cancer and diverticulitis patients were matched using propensity score, controlling for age, gender, race, type of operation (open vs laparoscopic) and comorbidities. The end-points of interest were infective complications, reoperation, anastomotic leakage, rebleeding, length of hospital stay and in-hospital mortality. After propensity score matching (diverticulitis 11192 patients, sigmoid cancer 11192 patients), the mean age was 65±12.5years, 53.8% were male and 61.5% were Caucasian. Only 18.0% of the operations were done by laparoscopy. The overall complication rate was 17.7% and the in-hospital mortality rate was 0.9%. The diverticulitis group had a higher rate of surgical site infection (3.2% vs 2.6%, P=0.004), intra-abdominal abscess formation (1.2% vs 0.4%, P<0.0001) and reoperation (6.1% vs 4.1%, P<0.0001) compared with the cancer group. The cancer group had a higher incidence of pneumonia (1.9% vs 1.5%, P=0.01) and anastomotic leakage (9.2% vs 8.3%, P=0.001). There was no difference in sepsis, deep vein thrombosis, respiratory failure, renal failure, rebleeding, overall complication rate or length of hospital stay. Subgroup analysis showed a higher in-hospital mortality for cancer than for diverticulitis patients whether resected by open or by laparoscopic surgery. Although elective sigmoidectomy for diverticular disease has a higher risk of infective complications, elective sigmoidectomy for cancer has a higher risk of anastomotic leakage.

Surgery versus conservative management for recurrent and ongoing left-sided diverticulitis (DIRECT trial): an open-label, multicentre, randomised controlled trial

Patients with recurrent or persisting complaints after an episode of left-sided diverticulitis are managed with either conservative measures or elective sigmoidectomy. To date, there are no data from randomised trials. We aimed to establish which treatment leads to a better quality of life for patients with diverticulitis. We did an open-label, multicentre, randomised controlled trial (DIRECT trial) in 24 teaching and two academic hospitals in the Netherlands. Patients aged 18-75 years presenting with either recurrent (three or more presentations with clinical signs of acute diverticulitis within 2 years) or persistent abdominal complaints (ongoing lower left abdominal pain or persistent change in bowel habits for ≥3 months) after an episode of left-sided diverticulitis, confirmed by CT, ultrasound, or endoscopy, were included. Patients were excluded if they had previous elective or emergency surgery for acute sigmoid diverticulitis, an absolute operation indication, suspicion of a colorectal malignancy, with a preoperative or postoperative risk greater than III (on the American Society of Anesthesiologists classification), or were unable to complete questionnaire or follow-up. Patients were randomly assigned (3:3) to receive conservative management or elective (laparoscopic) sigmoidectomy using a digital randomisation system, stratified by type of disease and centre, with a block size of six. Patients, physicians, and researchers were not masked to treatment allocation. Our primary endpoint was health-related quality of life, measured by the Gastrointestinal Quality of Life Index (GIQLI) at 6 months after inclusion or surgery, depending on randomisation group. This trial is registered with trialregister.nl, number NTR1478, and is closed for inclusion. Between July 1, 2010, and April 1, 2014, we randomly assigned 109 patients to receive surgical treatment (resection; n=53) or conservative management (n=56), after which the Data Safety and Monitoring Board prematurely terminated the trial because of increasing difficulties in recruitment. 47 (89%) of 53 patients received surgical treatment and 43 (77%) of 56 patients received conservative management. The GIQLI score at 6 months' follow-up was significantly higher in patients randomly assigned to receive surgical treatment (mean 114·4 [SD 22·3]) than conservative management (100·4 [22·7]; mean difference 14·2, 95% CI 7·2-21·1, p<0·0001). 43 (38%) of 109 patients had a severe adverse event in the first 6 months after treatment (18 [34%] of 53 patients in the surgical treatment group vs 23 [40%] of 57 patients in the conservative treatment group). Seven (15%) patients who received surgical treatment developed anastomotic leakage. Of the 56 patients assigned to be treated conservatively, 13 (23%) ultimately underwent elective resection due to ongoing abdominal complaints, with no anastomotic leakage. We recorded no patient deaths. Elective sigmoidectomy, despite its inherent risk of complications, results in better quality of life than conservative management in patients with recurrent and persisting abdominal complaints after an episode of diverticulitis.

Diverticular Abscess Managed With Long-term Definitive Nonoperative Intent Is Safe.

Initial nonoperative management of diverticular abscess has become the standard of care; however, the need for elective resection after this index episode is unclear. The purpose of this study was to assess the long-term outcomes of expectant management after initial nonoperative treatment of diverticular abscess. This was a retrospective chart review with prospective telephone follow-up of patients. The study was conducted at a large tertiary academic colorectal surgery practice in Canada. Adult patients with CT-documented acute sigmoid diverticulitis complicated by abscess managed nonoperatively from 2000 to 2013 were included. Long-term definitive nonoperative management of diverticular abscess. The primary outcome was emergency sigmoidectomy or death from recurrent diverticulitis. Secondary outcomes were recurrent diverticulitis and elective sigmoidectomy for diverticulitis. Of 135 patients with acute diverticulitis complicated by abscess, a total of 73 patients were managed with nonoperative intent and long-term expectant management. The median follow-up was 62 (Q1 to Q3: 28-98) months. After resolution of the index episode, 22 patients [30.1% (95% CI, 19.6%-40.6%)] experienced a recurrent episode of diverticulitis at a median of 23 (range, 9-40) months. Two patients [2.7% (95% CI, -1.0% to 6.4%)] had a recurrent episode with peritonitis that required sigmoidectomy with stoma at 6 and 64 months. Both patients underwent reversal after 4 and 8 months. Seven [9.6% (95% CI, 2.8%-16.4%)] patients experienced a complicated recurrence and underwent an elective sigmoidectomy [median time to colectomy, 33 (range, 16-56) months]. Thirteen patients [17.8% (95% CI, 9.0%-26.6%)] experienced an uncomplicated recurrence, all of whom were managed with continued nonoperative intent [median follow-up, 81 (range, 34-115) months]. No mortality occurred. On multivariate logistic regression, female gender (p = 0.048) and a previous episode of uncomplicated diverticulitis before the index diverticular abscess (p = 0.020) were associated with a recurrent episode. This study was limited by its retrospective design and modest sample size. After initial successful nonoperative management of diverticulitis with abscess, expectant management with nonoperative intent is a safe long-term option with low rates of surgery, especially in the emergency setting.

Transrectal Rigid-Hybrid Natural Orifice Translumenal Endoscopic Sigmoidectomy for Diverticular Disease: A Prospective Cohort Study

Our goal was to evaluate the feasibility of transrectal rigid hybrid natural orifice translumenal endoscopic surgery (NOTES) sigmoidectomy (trNS) in a series of consecutive prospective patients with diverticular disease. The NOTES for left colectomy offers patients reduced pain and easier recovery. Limited data are available for trNS, which is considered safe for various indications. However, the technique is not standardized, and patients in the reported series are highly selected. Patients scheduled for trNS were entered into a prospective registry on an intention-to-treat basis. The primary endpoint was trNS feasibility, and secondary endpoints were morbidity, pain, length of stay, and inflammatory response. A medial-to-lateral dissection with full mobilization of the splenic flexure and total intracorporeal anastomosis was performed. The rectum was covered with a wound protector for transrectal extraction. Of 95 elective sigmoidectomies, 81% (n = 77) were enrolled for either transvaginal NOTES resection (n = 37) or trNS (n = 40). There was no difference in body mass index or indication between patients undergoing laparoscopic-assisted sigmoidectomy (LAS), transvaginal resection, or trNS, although trNS patients were younger. Mainly because of a mismatch of bulky specimen and narrow pelvis, 17.5% of trNS were converted to LAS. Major morbidity was 10%, including 2 septic complications. During the study, the anastomosis technique was changed from double stapled end-to-end to side-to-end anastomosis. Transrectal rigid hybrid natural orifice translumenal endoscopic sigmoidectomy is feasible and safe in a high proportion of unselected consecutive patients with diverticular disease undergoing elective treatment. Intracorporeal side-to-end anastomosis is the preferred technique, and trNS should be offered for elective sigmoidectomy presupposing advanced laparoscopic experience.

Sigmoid stricture associated with diverticular disease should be an indication for elective surgery with lymph node clearance

The literature concerning stricture secondary to diverticulitis is poor. Stricture in this setting should be an indication for surgery because (a) of the potential risk of cancer and (b) morbidity is not increased compared to other indications for colectomy. The goal of this report is to study the post-surgical morbidity and the quality of life in patients after sigmoidectomy for sigmoid stricture associated with diverticular disease. This is a monocenter retrospective observational study including patients with a preoperative diagnosis of sigmoid stricture associated with diverticular disease undergoing operation between Jan 1, 2007 and Dec 31, 2013. The GastroIntestinal Quality of Life Index was used to assess patient satisfaction. Sixteen patients were included of which nine were female. Median age was 69.5 (46-84) and the median body mass index was 23.55kg/m(2) (17.2-28.4). Elective sigmoidectomy was performed in all 16 patients. Overall, complications occurred in five patients (31.2%) (4 minor complications and 1 major complication according to the Dindo and Clavien Classification); none resulted in death. Pathology identified two adenocarcinomas (12.5%). The mean GastroIntestinal Quality of Life Index was 122 (67-144) and 10/11 patients were satisfied with their surgical intervention. Sigmoid stricture prevents endoscopic exploration of the entire colon and thus it may prove difficult to rule out a malignancy. Surgery does not impair the quality of life since morbidity is similar to other indications for sigmoidectomy. For these reasons, we recommend that stricture associated with diverticular disease should be an indication for sigmoidectomy including lymph node clearance.

Laparoscopic Lavage and Drainage in the Management of Complicated Diverticulitis: Review of the Literature

Introduction: Diverticular disease affects more than 60% of adults aged older than 70. The lifetime prevalence of diverticulitis is 4%-25%, 20% of which will experience severe complications, and 1% will require emergent surgery. We review the most relevant literature regarding the management of complicated acute diverticulitis with laparoscopic lavage and drainage (LLD). Discussion: Hartmann Procedure (HP) is considered the current gold standard for treating complicated diverticulitis; it is associated with a high mortality and morbidity. LLD is reported to improve outcomes. In addition, it may act either as a definitive procedure or as a bridge and allow for a latter elective sigmoidectomy. There is only one preliminary report of a prospective randomized trial regarding this matter (DILALA trial) which fails to demonstrate decreased morbidity and mortality between LLD vs. HP.

Endoscopic reduction of a volvulus of the sigmoid colon in pregnancy: case report and a comprehensive review of the literature.

Sigmoid volvulus is a rare, but serious, complication that can occur during pregnancy. We present a case of a 33-year-old pregnant female in the third trimester with a sigmoid volvulus. Detorsion of the volvulus was performed during colonoscopy. The patient underwent an elective sigmoidectomy at a later date. Prompt diagnosis of the volvulus sigmoid is critical to minimize fetal and maternal morbidity and mortality. Sigmoidoscopic detorsion or surgical resection are the treatment options, depending on bowel viability. A review of the literature was done.
