[Laparoscopic resection of a giant colon diverticulum : Case report and review of the literature]. / Laparoskopische Resektion eines Riesenkolondivertikels : Fallbericht und Literaturübersicht.

BACKGROUND: Giant diverticula are rare complications of diverticular disease. Current opinion regards operative therapy as the method of choice for the treatment of symptomatic giant diverticula; however, there is neither consensus about the technique nor about the necessary extent of resection. Based on a non-systematic review of the literature, an overview of giant diverticula in terms of epidemiology, pathology and classification is given. The current case is considered with respect to appropriate diagnostic procedures and possible therapeutic options. CASE PRESENTATION: An 80-year-old female patient presented to the emergency department with abdominal pain and dyspnea. A computed tomography scan showed a large gas-filled structure in the upper left abdomen adjacent to the left colon. A giant colonic diverticulum was suspected and laparoscopy was performed. Intraoperatively, the diagnosis of a giant colon diverticulum located at the splenic flexure was confirmed. An unremarkable diverticulosis only was found in the descending colon. The giant diverticulum was treated by an atypical colon wedge resection and the postoperative course was uneventful. DISCUSSION: This case report describes a laparoscopic atypical colon wedge resection as treatment of a giant colon diverticulum. Only four laparoscopic bowel resections in terms of sigmoid resections or hemicolectomy with primary anastomosis have been reported. Minimally invasive surgery can be a valuable alternative to open procedures. In the current case a laparoscopic atypical colon wedge resection was safely performed. This option might be considered as an alternative to extended resections of giant diverticula. Localization of the giant diverticulum and the simultaneous existence of diverticular disease are the main criteria for the decision between the different operative approaches.

Giant colonic diverticulum: clinical presentation, diagnosis and treatment: systematic review of 166 cases.

AIM: To investigate the clinical presentation, diagnosis, and treatment of giant colonic diverticulum (GCD, by means of a complete and updated literature review). GCD is a rare manifestation of diverticular disease of the colon. Less than 200 studies on GCD were published in the literature, predominantly case reports or small patient series. METHODS: A systematic review of the literature was performed using the Embase and PubMed databases to identify all the GCD studies. The following MESH search headings were used: "giant colonic diverticulum"; "giant sigmoid diverticulum". The "related articles" function was used to broaden the search, and all of the abstracts, studies, and citations were reviewed by two authors. The following outcomes were of interest: the disease and patient characteristics, study design, indications for surgery, type of operation, and post-operative outcomes. Additionally, a subgroup analysis of cases treated in the last 5 years was performed to show the current trends in the treatment of GCD. A GCD case in an elderly patient treated in our department by a sigmoidectomy with primary anastomosis and a diverting ileostomy is presented as a typical example of the disease. RESULTS: In total, 166 GCD cases in 138 studies were identified in the literature. The most common clinical presentation was abdominal pain, which occurred in 69% of the cases. Among the physical signs, an abdominal mass was detected in 48% of the cases, whereas 20% of the patients presented with fever and 14% with abdominal tenderness. Diagnosis is based predominantly on abdominal computed tomography. The most frequent treatment was colic resection with en-bloc resection of the diverticulum, performed in 57.2% of cases, whereas Hartmann's procedure was followed in 11.4% of the cases and a diverticulectomy in 10.2%. An analysis of sixteen cases reported in the last 5 years showed that the majority of patients were treated with sigmoidectomy and en-bloc resection of the diverticulum; the postoperative mortality was null, morbidity was very low (1 patient was hospitalized in the intensive care unit for postoperative hypotension), and the patients were discharged 4-14 d after surgery. CONCLUSION: Giant colonic diverticulum is a rare manifestation of diverticular diseases. Surgical treatment, consisting predominantly of colonic resection with en bloc resection of the diverticulum, is the preferred option for GCD and guarantees excellent results.

[The current view of surgical treatment of diverticular disease]. / Soucasný pohled na chirurgickou lécbu divertikulární choroby.

AIM: The aim of our prospective dynamic cohort trial is the evaluation of indication for surgery for diverticular disease and the evaluation of morbidity and mortality. MATERIAL AND METHOD: All patients operated for diverticular disease and its complications were involved in the study. The conservatively treated patients were not involved. 104 patients with diverticular disease and its complication were operated from August 2007 till July 2008.46 men and 58 women at average age of 63.9 (31-85) years were in this group. 78 patients were electively operated in noninflammatory stage of diverticular disease. 3 patients of them had colovesical or enterocolical fistulas. An elective laparoscopic colon sigmoid resection was performed by 74 patients and a laparoscopic left hemicolectomy was performed by 4 patients. An end-to-end stapled colorectal suture was performed by all patients. An excision of fistula from urinary bladder and a segment resection of small bowel were performed in the case of fistula presence. In connection with previously repeated diverticulitis attacks or after previous surgeries, adhesiolysis was performed by 23 patients. 26 patients were operated for acute complication of diverticular disease. 24 patients of this group were operated for acute diverticulitis and 2 patients for diverticular bleeding. 23 colon sigmoideum resections, 2 left hemicolectomies, and once ileocecal resection were performed. The primary bowel suture was performed by 20 patients and Hartmaruts operation was performed by 4 patients. RESULTS: The indication for surgery follows the classification according to Hansen and Stock. The abdominal postoperative complications (wound infection, anastomotic leak, prolongated bowel atonia, and others) occurred by elective operated group in 9% and by acute operated group in 26.9%. The overall abdominal postoperative complications occurred in all the involved patients in 13.4%. The extraabdominal postoperative complications (urinary infection or retention, cardiopulmonary complications, trombosis/embolia, postoperative qualitative conscious disorder, renal insufficiency, and others) occurred by elective group in 19.6% and by acute operated group in 50%. Overall extraabdominal postoperative complications occurred in all involved patients in 26.90%. The mortality was 0%. The conversion rate in elective group was 3.8% (3 pts.). An anastomosis leak occurred once (1%) by elective operated patient. An acute reoperation with resection according to Hartmann was performed. A small bowel loop perforation by coincidental adhesiolysis occurred once. A small bowel defect was identified and sutured by early laparoscopic reoperation. The conversion rate in acute group was 23.1% (6 pts.). The colonoscopy was necessary on 3rd day by 1 patient after left hemicolectomy for splenic flexure bleeding. This examination revealed bleeding from diverticulum in hepatic flexure. An endoscopic treatment was performed. An abscess in small pelvis occurred by this patient (12th postoperative day) and open drainage was performed. There was no anastomosis leak in group with acutely operated patients. CONCLUSION: The usage of standard classification is suitable for operation's indication for diverticular disease and its complications. It helps to determine the type and operation's strategy. The acute complicated diveticulitis has high morbidity and mortality. The early indication of selected patients with diverticular disease for elective colon sigmoideum resection protects against possible complication in the case of next attack of diverticulitis. It concerns the patients with recidivated uncomplicated and complicated forms of disease as well. The primary conservative treatment with percutaneous CT navigated drainage allows a postponed elective surgery. The primary resection with suture is better than the two stage surgery. The primary laparoscopic resection is safe procedure in almost all the cases. The primary suture can be safely performed in all elective cases for uncomplicated diverticulitis, chronic fistulas, obstruction, for primarily conservatively treated stages Hinchey I and II and possibly for all the selected patients with Hinchey III and IV stages with MPI lower as 21.

Comparison of POSSUM scoring systems and the surgical risk scale in patients undergoing surgery for complicated diverticular disease.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Obstructing giant colonic diverticulum.

We report the second case of an obstructing true colonic diverticulum. Of the 103 cases of giant sigmoid diverticulum found in the literature, 13% have been reported as true giant sigmoid diverticulum, ie, containing all layers of the colonic wall. Our 75-year-old patient had clinical symptoms for only 6 months, and endoscopy revealed an almost totally obstructing mass 20 cm from the anus. Surgical resection of the sigmoid colon with a primary anastomosis resolved all of the patient's obstructive symptoms. A flap-valve mechanism was the cause of this true giant colonic diverticulum. Microscopic examination of the diverticulum wall revealed all normal layers of colon wall.

Preservation and peeling of the inferior mesenteric artery in the anterior resection for complicated diverticular disease.

The authors, on the basis of 3 cases of complicated diverticular disease, discuss the indications to surgery, considering the advantages and disadvantages of the various surgical techniques and examining in particular the rules for a correct operation with resection and primary or secondary anastomosis. As they performed a rectosigmoidectomy with primary high colorectal anastomosis, they report the reasons why they adopted the preservation and peeling of the inferior mesenteric artery (IMA).

Experience with neuronal intestinal dysplasia (NID) in adults.

In paediatrics neuronal intestinal dysplasia (NID) has frequently been described, but in adults the clinical picture was not recognised. NID has been diagnosed in adults as well as children with impaired colonic motility since enzymehistochemical methods became available. Patients with primary chronic constipation (n = 41) and with diverticulosis of the sigmoid colon (n = 23) showed neuronal colonic dysplasia, whereas healthy controls (n = 15) had a normal innervation of the intestinal wall (p < 0.001). The results of this clinical study make a worthwile contribution to the understanding of the aetiology and pathogenesis of primary chronic constipation and diverticulosis of the colon in adults. Conservative treatment is usually unavailing and surgical intervention is needed. Hence, where strictly indicated, resection of the pathologically disturbed colon segment is often the only successful therapeutic procedure.

Irritable bowel syndrome and symptomatic diverticular disease--different diseases?

The influence of colonic diverticula on symptomatology and prognosis was investigated in 69 patients with irritable bowel syndrome. Roentgenograms at the time of diagnosis were blindly correlated to patient complaints and to result of follow-up 5 to 7 yr after the irritable bowel syndrome had been diagnosed. Patient complaints were not related to the presence or extent of diverticulosis. Half the patients had unchanged or aggravated symptoms at follow-up irrespective of diverticulosis. Accordingly, the presence of colonic diverticula did not change the natural history of the irritable bowel syndrome.

Right-sided diverticular disease of the colon: a morphological analysis of 16 cases.

Right-sided diverticular disease is uncommon and represents a heterogeneous group of cases with varying clinical presentation often confused with other disorders. Based on number, size, distribution and histological appearance of the diverticula, four distinct groups were identified, each with a distinct clinical presentation. Six patients had solitary false diverticula mimicking acute appendicitis and at operation were found to have inflamed caecal masses. Five patients had diverticula formed on the basis of defects in the muscularis propria. The mean age of these patients was 30 years older than the previous group and all of them presented with rectal haemorrhage, often confused with angiodysplasia clinically. At laparotomy the external appearance of the bowel was unremarkable. Three patients had diverticular disease similar to that seen in the left side of colon. Two patients had true congenital caecal diverticula confirming that the minority of caecal diverticula conforms to this group.

[Diverticulosis and diverticular disease (reference to a case of diverticular disease observed in 3 sisters)]. / Diverticolosi e malattia diverticolare (riferimento a un caso di malattia diverticolare osservato in 3 sorelle).

We started from this frequent and important intestinal pathology to emphasize the above mentioned observation of three cases where it was possible to apply three different medico-surgical techniques with excellent results.

Diverticular disease of the colon: surgical perspectives in the past decade.

Review of 475 cases of diverticular disease of the colon emphasized needs to stratify patients into clinical categories. Of 223 cases of diverticulosis coli, had significant colonic complaints which received no attention. Of 198 emergency admissions for acute diverticulitis, only 16 required emergency surgery. Resection in the face of serious peritonitis is not advisable. Twenty-seven elective resections gave excellent results. Three subtotal colectomies were successfully done for major bleeding. Final focus was on determination of therapy groups: medical, surgery advisable, and surgery inevitable.
