CT signs of diverticulum destruction in inflammatory complications of diverticular disease

AIM: to evaluate diagnostic capabilities of computed tomography in identifying the destruction of the diverticulum wall in complicated diverticular disease. PATIENTS AND METHODS: the prospective cohort study included 70 patients (38 female and 32 male median age - 57 ± 13), which underwent elective surgery for complicated diverticular disease. The following assessment criteria for CT were used: signs of diverticulum destruction, thickness of the bowel wall, length of inflammatory changes of colonic wall, length of pericolonic inflammation. The data of preoperative CT were compared with the morphology of removed bowel specimen. RESULTS: the sensitivity and specificity of CT were 96.8% and 97.4% in the detection of abscesses, 95% and 100% of colonic fistulas, and 100% and 97% pericolonic inflammation, respectively. Based on results of morphological studies of resected colon segment, two groups of patients were identified: with macroperforation (abscesses and fistulas) and microperforation (pericolic inflammatory mass). According to the ROC-analysis, colon wall thickness ≥ 0.7 cm, length of inflammatory changes of colonic wall ≥ 9.2 cm and the length of pericolonic inflammation ≥ 3.1 cm highly likely show microperforation. CONCLUSION: CT parameters of thickening of colon wall, length of inflammatory changes of colonic wall and the length of pericolonic inflammation seem to be significant for the possibility of predicting the presence of microperforation. New studies with a larger number of clinical cases are required.

Robotic Surgery for Complicated Diverticular Disease.

Diverticular disease is common, and increasing in prevalence worldwide. The treatment for acute and chronic diverticular disease has a huge clinical and economic burden. Surgery is standard for complicated diverticulitis, and there are several benefits to using robotic surgery in these cases. Complicated diverticular disease can result in fistula, fibrosis, and deranged anatomy, which present technical challenges to the surgeon. Understanding and anticipating these anatomical challenges is key to successful surgery. While fears of conversion in complicated cases may stop surgeons from using traditional laparoscopic surgery, robotic surgery is especially promising for enhancing dexterity, visualization, and facilitating completely minimally invasive surgery in these complicated cases. In this chapter, we review end-to-end technical strategies of robotic colorectal surgery for complicated diverticular disease, including cases with colovesicular, colovaginal, and colocutaneous fistulae.

The role of emergency laparoscopic surgery for complicated diverticular disease: A systematic review and meta-analysis.

Background:Laparoscopic surgery develops rapidly in both elective and emergency settings. The study aimed to determine the role of different laparoscopic methods for the emergency treatment of complicated diverticulitis.Methods:MEDLINE, EMBASE, Science Citation Index Expanded, and the Cochrane database were searched up to November 2019 to identify all published articles related to the topic. Statistical analysis was performed using Stata 15.Results:Fourteen publications were included in the analysis. Laparoscopic surgery was applied in 425 patients, and 493 patients underwent open colon resection (OCR). Postoperative mortality, morbidity, severe complications, and reoperation rates were not significantly different between the laparoscopic and open surgery groups. Subgroup analysis was performed based on the different laparoscopic methods (laparoscopic colon resection [LCR] and laparoscopic lavage and drainage [LLD]). Subgroup analysis indicated that LCR was superior to OCR in terms of morbidity, while OCR was superior to LLD in terms of severe complications.Conclusions:The safety of laparoscopic surgery for the emergency treatment of complicated diverticulitis is related to different surgical methods. LCR is suggested to be a better choice according to the postoperative outcomes. More definite conclusions can be drawn in future randomized controlled trials.

Association between diverticular disease requiring surgical intervention and mortality in the postlung transplant population - a retrospective cohort study.

Lung Transplant recipients are at increased risk of complicated diverticular disease. We aim to assess the rate of diverticular surgery in a postlung transplantation population and identify risk factors for surgery. We performed a retrospective cohort study of lung transplant recipients from 2007 to 2011. Demographic variables were evaluated with the Mann-Whitney U and chi-squared tests. Cox regression was performed to evaluate 1- and 2-year landmark survival, assess predictor variables of diverticular surgery and evaluate impact of surgery on CLAD development. Of 17 of 158 patients (10.7%) underwent diverticular-related surgery. Surgical patients had significantly worse survival than nonsurgical patients at 1year [aHR 2.93 (1.05-8.21), P=0.041] and 2year [aHR 4.17 (1.26-13.84), P=0.020] landmark analyses. Transplant indication of alpha-1 antitrypsin disease and cystic fibrosis were significantly associated with the need for diverticular surgery. Emergent surgery was associated with poorer survival [aHR 5.12(1.00-26.27), P=0.050]. Lung transplant patients requiring surgery for complicated diverticular disease have significantly poorer survival than those who do not require surgery. Surgery was more common in patients transplanted for A1AT and CF. Optimal assessment and risk stratification of diverticular disease is necessary to prevent excessive morbidity and mortality following transplantation.

Laparoscopic Emergency Surgery for Diverticular Disease That Failed Medical Treatment

Laparoscopic surgery has become the standard of treatment for elective management of diverticular disease. However, its use in the acute setting remains controversial. The aim of this study is to compare the outcomes of laparoscopic surgery with open surgery in the acute management of complicated diverticular disease that failed initial medical treatment. This is a single-center comparative retrospective cohort study. Patients undergoing surgery for complicated diverticular disease after an attempt at medical treatment from 2000 to 2011 were selected. Laparoscopic versus open surgery was compared. The primary outcomes were overall 30-day morbidity and mortality. Secondary outcomes were length of stay, time to resume diet, and need for a permanent stoma. Forty-two patients were identified by using medical records: 24 laparoscopic surgery and 18 open surgery. Baseline demographics, ASA classification, Acute Physiology and Chronic Health Evaluation scores, Hinchey classification, and Charlson Comorbidity Index did not differ between groups. The mean operative time was 36 minutes longer (p = 0.05) and blood loss was 460 mL less (p < 0.001) for laparoscopic surgery. Two patients (8.3%) in the laparoscopic surgery group required conversion to open surgery. There was no mortality. Overall morbidity was lower favoring laparoscopic surgery (16.7% vs 55.6%; p = 0.01). Two patients in the laparoscopic surgery group experienced an anastomotic leak compared with none in the open surgery group. Mean time to resume diet (3 vs 6.5 days; p < 0.01) and length of stay (5 vs 8 days; p = 0.04) were shorter for the laparoscopic surgery group. Rate of permanent stoma at last follow-up (median, 332 days) did not differ significantly between groups. This study is limited by selection bias. Compared with open surgery, laparoscopic surgery for patients in whom medical treatment for complicated diverticular disease failed is associated with favorable outcomes, including a reduced rate of morbidity and a shorter length of stay. When applied to selected patients, this approach appears to be a safe procedure with a low rate of conversion.

Laparoscopic surgery for complicated diverticular disease: a single‐centre experience

The role of laparoscopic surgery in the management of patients with diverticular disease is still not universally accepted. The aim of our study was to evaluate the results of laparoscopic surgery for diverticular disease in a centre with a specialist interest in minimally invasive surgery. All diverticular resections carried out between 2006 and 2010 were reviewed. Data recorded included baseline demographics, indication for surgery, operative details, length of hospital stay and complications. Complicated diverticular disease was defined as diverticulitis with associated abscess, phlegmon, fistula, stricture, obstruction, bleeding or perforation. One hundred and two patients (58 men) who had surgery for diverticular disease were identified (median age 59 years, range 49-70 years). Sixty-four patients (64%) had surgery for complicated diverticular disease. The indications were recurrent acute diverticulitis (37%), colovesical fistula (21%), stricture formation (17%) and colonic perforation (16%). Sixty-nine cases (88%) were completed by elective laparoscopy. Postoperative mortality was 0%. For elective cases there was no difference in morbidity rates between patients with complicated and uncomplicated diverticular disease. The overall anastomotic leakage rate was 1% and the wound infection rate 7%. There was a nonsignificant trend to higher conversion to open surgery in the elective group in complicated (11.4%) compared with uncomplicated patients (5.2%) (P=0.67). Electively, the rate of stoma formation was higher in the complicated (31.6%) than the uncomplicated group (5.2%) (P<0.02). Laparoscopic surgery for both complicated and uncomplicated diverticular disease is associated with low rates of postoperative morbidity and relatively low conversion rates. Laparoscopic surgery is now the standard of care for complicated and uncomplicated diverticular disease in our institution.

Emergency laparoscopic surgery for complicated diverticular disease

The aim of this study was to analyse the outcome of emergency laparoscopic surgical management of complicated diverticular disease. A prospectively collected electronic database of all colorectal laparoscopic procedures between April 2001 and September 2007 has been used to identify outcomes in patients presenting with complicated diverticular disease. Sixty-six patients (28 men), median age 69 years (23-95), ASA grade II (12), III (38), IV (16) have undergone emergency surgery for complicated diverticulitis--Hinchey grades I (27), II (29), III (7) and diverticular bleeding (3) over a 6(1/2)-year period: 43 high anterior resections, 17 Hartmann's resections and seven low anterior resections. Diverticular fistulas were seen in 16 patients: colovaginal (7), colovesical (2), colo-fallopian (4), entero-colic (3). The median operation time was 110 min (45-195 min). There was one conversion to open surgery. Postoperative analgesia was provided by intravenous Paracetamol in 33 patients (50%), patient-controlled analgesia in 24 (36%), oral Paracetamol and Oramorph (12%) and epidural opioid infusion (1.5%). The median time to normal diet was 24 h (4 h-6 days) and median hospital stay 5 days (2-30). There were two deaths (3.3%); anastomotic leak, ventricular fibrillation (VF) cardiac arrest. Other complications included: wound infection eight (12%), anastomotic leak four (8%), port-site hernia one and one case of Clostridium difficile colitis requiring colectomy. There were five (7.5%) returns to theatre and two readmissions (3%). Laparoscopic resectional surgery in complicated diverticular disease is a feasible, safe and a largely predictable operation that allows for early hospital discharge and, in our opinion, improved patient care. We are encouraged to continue to offer our patients the option of an emergency laparoscopic resection.

Prospective multicentre evaluation of adverse outcomes following treatment for complicated diverticular disease

The choice of operation for complicated diverticular disease is contentious. The aim of this study was to investigate adverse events following restorative (primary resection and anastomosis, PRA) and non-restorative (Hartmann's procedure, HP) surgery for complicated diverticular disease. Five hundred and thirty-nine patients who presented with complicated diverticular disease in 42 centres over a 12-month period from January 2003 were considered for the study. Data were collected prospectively from 248 patients (46.0 per cent) who underwent PRA and 167 (31.0 per cent) who had HP. A propensity score was developed for case-mix adjustment. Multifactorial logistic regression was used to evaluate differences in operative outcomes. Mortality, surgical and medical complication rates were 4.0, 31.0 and 13.7 per cent respectively after PRA, and 23.4, 53.3 and 40.7 per cent for HP (all P < 0.001). After adjusting for the propensity score, the HP group had a 2.1- and 1.9-fold increase in medical and surgical complications respectively compared with those who had PRA, whereas the operative mortality rate was not significantly different. Non-colorectal surgeons performed a significantly higher proportion of HPs in the non-elective setting than colorectal surgeons (80.6 versus 60.4 per cent; chi(2) = 8.31, 1 d.f., P = 0.004). PRA with or without a proximal diversion is more often performed non-electively by specialist colorectal surgeons. It may be a safe procedure for complicated diverticular disease in selected patients as it may be associated with fewer postoperative adverse events.

Comparison of POSSUM Scoring Systems and the Surgical Risk Scale in Patients Undergoing Surgery for Complicated Diverticular Disease

This study was designed to evaluate the accuracy of the Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity, Portsmouth-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity, colorectal-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity, and the Surgical Risk Scale for the treatment of patients with complicated diverticular disease. Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity variables were prospectively recorded for 324 patients undergoing colorectal resections in 42 hospitals in the United Kingdom from January to December 2003. The accuracy of each model was evaluated by measures of discrimination, calibration, and subgroup analysis. The overall operative mortality was 10.8 percent (Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity-estimated mortality rate, 21.9 percent; Portsmouth-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity-estimated mortality rate, 10.5 percent; colorectal-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity-estimated mortality rate, 10 percent; Surgical Risk Scale-estimated mortality rate, 38.2 percent). Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity and the Surgical Risk Scale over-predicted mortality in young patients (P < 0.001) and Portsmouth-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity underpredicted mortality in elderly patients (P < 0.001). Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity and the Surgical Risk Scale overpredicted mortality in patients with generalized peritonitis (Hinchey III and IV). There was no significant difference between the observed and colorectal-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity predicted mortality across patient subgroups and when the overall sample was considered. The study suggested a lack of calibration of Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity, Portsmouth-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity, and the Surgical Risk Scale at the extreme of age and for patients with severe peritoneal contamination. Colorectal-Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity was found to accurately evaluate mortality arising from complicated diverticular disease.

Results of colectomy for diverticular disease of the colon.

A retrospective study of 71 patients who had a colonic resection for diverticular disease at one hospital during a 7-year period was undertaken. Patients were divided into those undergoing surgery for complications of diverticular disease (49) and those in whom abdominal pain and an altered bowel habit were attributed to the presence of diverticular disease in the absence of any detectable complication (22). In both groups major complications occurred after operation. The incidence of complications was greater when surgery was undertaken in stages to effect colonic resection and restoration of intestinal continuity. Symptoms were more often cured or relieved in those patients undergoing surgery for complicated diverticular disease than in those with 'uncomplicated' disease. These poor results may be due to incorrectly attributing symptoms to diverticula which happened to be present.

Is laparoscopic surgery applicable to complicated colonic diverticular disease?

Expanding upon our experience with laparoscopic surgery for colonic benign and malignant processes and for bowel obstruction, we have reviewed our experience with minimal access laparoscopic surgery for complicated diverticular disease. We propose an approach of surgical care incorporating diagnostic laparoscopy in those not responding to medical therapy alone. Our study includes data from two different surgical teams working in separate hospital-and-patient environments. Our theory that laparoscopy could be widely applicable to this complex disease process is borne out by experience in both locations. One hundred forty-eight patients were managed by laparoscopic or laparoscopically assisted methods with 18 patients requiring drainage only without resection. Our management of 148 of 164 patients (90%) by laparoscopic approach was successful, with a very acceptable morbidity of 5% in the elective cases and decreased ileus (20% of open vs 7% laparoscopic) in acute complicated cases. Elective resections required hospitalization of 4-5 days, demonstrating the benefits of incorporating laparoscopy in the care of these cases, particularly when compared to standard open procedures requiring 8 days' hospitalization. We believe complications of diverticular disease including abscess, perforation, fistula, and bleeding can potentially be managed in this way by minimal access procedures, decreasing postoperative wound problems, decreasing length of hospitalization and overall morbidity, and improving patient care.

Emergency surgery for complicated diverticular disease. A five-year experience.

Ninety-three patients who underwent surgery were studied retrospectively over a five-year period for complications of diverticular disease, including free perforation in 32 patients (with fecal peritonitis in 8), inflammation or peritonitis in 22 patients, an abscess in 11 patients, and intestinal obstruction in 14 patients. Sixty-eight patients (73 percent) had systemic symptoms and signs consistent with serious sepsis. There has been a growing popularity of the Hartmann procedure throughout the study period. The overall 30-day mortality rate was 10.8 percent. Because of a high proportion of poor-risk patients, the Hartmann group fared particularly badly compared with those who had other operations, with a 28 percent mortality rate, 69 percent incidence of major complications, and one third of the survivors having a permanent colostomy. Other operative procedures are discussed, but until prospective data become available, it is unlikely that the widespread popularity of the Hartmann procedure will decline. Therefore, the importance of meticulous attention to technical detail is stressed if results are to improve.

Distal colomyotomy: follow-up of 37 cases.

The 3-7-year follow-up results of 37 patients undergoing the operation of distal colomyotomy are reported. Twenty-five underwent surgery for uncomplicated diverticular disease; there was no mortality but 40 per cent of patients had recurrent symptoms. Twelve patients underwent surgery for complicated diverticular disease, with an operative mortality of 16-6 per cent and a recurrent symptom rate of 37-5 per cent.
