Endoscopic management of a rare granulation polyp in a colonic diverticulum

There are many case reports on colon diverticula that cause irritable bowel syndrome, constipation, bleeding, diverticulitis, stricture due to multiple recurrences of diverticulitis, and perforation. However, few articles have examined neoplasms that arise from a diverticulum, such as adenoma and adenocarcinoma, and there have been no reports of granulation polyps that arise from a colon diverticulum after recurrent diverticulitis. We observed a rare granulation polyp that arose from a diverticulum as a result of repeated episodes of local diverticulitis. Narrow band imaging magnified colonoscopy was very useful to diagnose the polyp as a granulation polyp because of the absence of a pit pattern on the surface of the polyp. We successfully resected the polyp using endoscopic mucosal resection. We inverted the diverticulum, and the resected stalk of the polyp was used to close the diverticulum with an over-the-scope clip. If a granulomatous polyp could arise from a diverticulum, differential diagnosis between a colon neoplasm and a granulomatous polyp would not only be difficult but also necessary for suitable endoscopic treatment.

[Results of surgical rehabilitation of patients in the presence of external colonic fistula in conditions of district hospital]

Results of treatment of 102 patients for a variety of injuries and surgical diseases of the colon, who performed the intervention, culminating in the formation of the external colonic fistula (ECF) were analyzed. After reconstructive and restorative surgery for ECF, all patients were alive. Postoperative complications occurred in 15 (20.8%) patients, including intraabdominale--in 2 (2.8%). The optimal timing of surgical rehabilitation and volume reduction or reconstructive surgery in patients over the ECF should be determined strictly individual basis, taking into account the severity and nature of the illness or injury, which required imposition of an stoma, the severity of postoperative scar and local inflammatory processes in the abdominal cavity, in laparotomic wound and fistula. Performing simultaneous operations in the surgical rehabilitation of patients with ECF practically does not increase the risk of postoperative complications.

[Manual-assisted laparoscopic interventions in coloproctologic diseases]

Feasibility of manual-assisted laparoscopic surgery in the treatment of coloproctologic diseases was designated. The investigation included 25 patients operated on for diseases of the colon. In 11 of them made manual-assisted laparoscopic surgery. Length of cut with manual-assisted laparoscopic interventions in 3.8 times less conventional laparotomy section, the total blood loss was 2.3 times less than in open surgery. Duration of patients rehabilitation after such surgery is 1.8 times less than after laparotomy. Laparoscopic surgery of the hand asystens in coloproctology mini-invasive is, however, retain the advantages of open surgery. At the present stage of coloproctology are, on the one hand, is the first step to classic laparoscopic surgery on the other--an alternative to conversion.

[Colovesical fistula as a complication of diverticular disease]

The results of research on the clinical picture, features of manifestation, diagnosis, and treatment of patients with diverticular disease complicated by sigmovesical fistula are presented. The study included 31 patients (19 [61.3%] men, 12 [38.7%] women), aged 32-83 (55.6 +/- 7.1) years. Diagnostic program included physical examination, laboratory blood and urine tests, endoscopic, radiological, ultrasound examinations. All patients underwent different interventions according to the severity and extent of the inflammatory process, the involvement of other organs of the abdominal cavity and the extent of diverticular lesions of the colon. Long-term results were assessed in all patients in a period of 5 months to 12 years, with a median follow-up 4.7 years. It is shown that the clinical manifestations of intestinovesical fistula did not match the severity of complications, and were subclinical. Timing for referral the patient to coloproctologist was 5 months after the occurrence of first clinical signs. In any case, conservative treatment has not led to spontaneous colovesical fistula closure. Average size of parafistulous infiltration on the wall of the bladder and perivesical tissue was 6.5 +/- 2.4 cm. All the patients underwent different types of colon resection. Postoperative complications did not requiring recurrent surgery were detected in 5 (16.1%) patients. None of these has experienced recurrence complications of diverticular disease. For the optimization the treatment strategy, physicians should follow multidisciplinary approach immediately after revealing the patient with persistent bacteriuria, pneumaturia and fecaluria. The surgery is the method of choice in the treatment of colovesical fistula as a complication of diverticular disease.

Stercoral colonic diverticulum perforation with jejunal diverticulitis mimicking upper gastrointestinal perforation

Stercoral perforation of the colon is an unusual pathological condition with fewer than 150 cases reported in the literature to date. We present a case of stercoral colonic perforation mimicking upper gastrointestinal perforation, which was diagnosed by computed tomography preoperatively. However, at laparotomy, stercoral colonic diverticulum perforation with jejunal diverticulitis became the most appropriate diagnosis.

Chest ultrasounds to guide manual reexpansion of a postoperative pulmonary atelectasis: a case report

Reexpansion of a pulmonary atelectasis is often difficult, even after removing possible causes of bronchial obstruction. Chest ultrasounds, inexpensive and readily available at the patient bedside, may offer valuable support to guide recruitment maneuvers. We report the case of a 57-year-old woman that developed a complete collapse of the left lung seven days after undergoing an intestinal resection for perforation. A mucous plug occluding the main bronchus was removed with bronchoscopy, but persistent hypoxemia required mechanical ventilation; 24 hours later, an attempt to wean the patient from the ventilator failed. Chest X-rays revealed the persistence of a partial collapse of the left inferior lobe associated with a pleural effusion. A chest ultrasound confirmed the presence of a lung consolidation and of a modest pleural effusion. Manual reexpansion was then attempted, and ventilatory pressures as well as the duration of forced inspirations were based on real-time ultrasound images. Complete reexpansion was achieved within a few minutes and confirmed by chest X-ray. The patient was weaned from mechanical ventilation on the same day and discharged from ICU three days later.

Giant cecal diverticulum in a child

A 12-year-old girl with abdominal pain and fever underwent urgent surgery. As was suspected on computed tomographic scan, a large diverticular mass adherent to the cecum was identified. A diverticulectomy was performed. We report this rare case of a giant cecal diverticulum and provide an overview of known literature.

Benefits of laparoscopy: does the disease condition that indicated colectomy matter?

The benefits of laparoscopic (LC) over open colectomy (OC) have been well characterized for a variety of conditions. Whether the relative benefits of LC differ for different conditions has not been previously investigated. The aim of this study was to identify whether there are differences in benefits of LC for colon cancer (CC), Crohn's disease (CD), and diverticular disease (DD). Data of patients with CC, CD, and DD undergoing elective colectomy from January 2000 to December 2007 were identified from departmental databases. Patients with CC, CD, and DD undergoing LC were matched 1:1 for diagnosis, gender, body mass index, surgical procedure, American Society of Anesthesiologists scale, and date of surgery to patients undergoing OC. TNM stage was also matched for patients with CC. Two hundred eighty-nine patients undergoing LC (CC, 93; CD, 140; DD, 56) were matched 1:1 to 289 patients undergoing OC. Median age was 49 years (range, 14 to 91 years) in LC and 52 years (range, 14 to 98 years) in OC (P = 0.35). All other matched criteria were also similar in both groups. The conversion rate to OC was 13 per cent (n = 36). Patients undergoing LC had significantly shorter lengths of stay (LOS) (3 days [range, 1 to 70 days] vs 6 days [range, 1 to 37 days], P < 0.001) and lower estimated blood loss (EBL) (100 mL [range, 10 to 1750 mL] vs 200 mL [range, 10 to 1700 mL], P < 0.001). Median operative time was similar in both groups (LC: 145 minutes [range, 35 to 431 minutes] vs OC: 135 minutes [range, 23 to 485 minutes], P = 0.54). The conversion rate was lower for DD (2%) when compared with CC (18.9%) and CD (13.4%). Improvement in EBL with LC was least pronounced in patients with CD and most pronounced in patients with DD (P interaction < 0.001). In the LC group, patients with DD presented less postoperative complications (P = 0.009). LC results in reduced LOS and EBL with similar complications rates when compared with OC. The benefits of LC are more pronounced in DD when compared with CD and CC.

[Dynamic computed tomography is useful for the diagnosis and colonoscopic treatment of colonic diverticular bleeding]

We investigated whether emergency dynamic computed tomography (CT) is helpful to identify bleeding colonic diverticulum treatable by colonoscopy. We enrolled 95 consecutive patients given diagnoses of colonic diverticular bleeding at Hiroshima City Hospital in the present study, of whom 60 underwent CT before colonoscopy (CT group), and 35 underwent colonoscopy alone (CS group). In the CT group, bleeding diverticula were identified and treated by colonoscopy in 31 of 32 (96.9%) patients in whom extravasation was detected by CT. The interval between bleeding being recognized and CT (median 1.0 hours) in patients in whom extravasation was detected by CT was shorter than that in whom extravasation was not detected (median 5.0 hours). To identify and treat bleeding diverticula by colonoscopy, the use of emergency dynamic CT prior to colonoscopy is recommended.

Elective laparoscopic sigmoid resection for diverticular disease has fewer complications than conventional surgery: a meta-analysis

BACKGROUND

We performed a meta-analysis of published literature comparing the complications after open and laparoscopic elective sigmoidectomy for diverticular disease.

METHODS

Electronic databases were searched from January 1991 to March 2009. A systematic review was performed to obtain a summative outcome.

RESULTS

Nineteen comparative studies involving 2,383 patients were analyzed. There were 1,014 patients in the laparoscopic group and 1,369 patients in the open group. There was no significant heterogeneity among any of the complications analyzed. Patients in the laparoscopic sigmoid resection group had fewer wound infections (fixed effects model: risk ratio [RR], .54; 95% confidence interval [CI], .36-.80; z, -3.05; P < .01; random effects model: RR, .59; 95% CI, .39-.89; z, -2.54; P < .05), blood transfusions (fixed effects model: RR, .25; 95% CI, .10-.60; z, -3.10; P < .01; random effects model: RR, .28; 95% CI, .11-.68; z, -2.81; P < .01), and ileus rates (fixed effects model: RR, .37; 95% CI, .20-.66; z, -3.34; P = .001; random effects model: RR, .37; 95% CI, .20-.68; z, -3.21; P = .001) compared with open sigmoid resections. No difference was seen for medical complications, need for rehospitalization, and reoperation.

CONCLUSIONS

Laparoscopic sigmoid resection is safe and has fewer postoperative surgical complications. This approach should be considered for elective cases, however, more randomized controlled trials are required to strengthen the evidence.
