Optimal Operative Strategy for Hinchey III Sigmoid Diverticulitis: A Decision Analysis

Functional outcome after Hartmann's reversal surgery using LARS, COREFO & QoL scores

BACKGROUND

Functional complaints after colorectal surgery have a profound effect on quality of life (QoL). Our goal was to investigate the prevalence of functional complaints and quality of life after Hartmann's reversal surgery.

METHOD

A cross-sectional study was performed where one hundred nineteen patients were included. All patients underwent Hartmann's reversal procedure between 2007 and 2019. All patients were asked to complete 3 validated questionnaires related to bowel function in benign and colorectal cancer surgery as well as general QoL.

RESULTS

The response rate was 67%. Among responders, 32.8% reported LARS-like symptoms whereas 25% had significant COREFO Scores (>15). Higher LARS and COREFO scores were significantly associated with worse global QoL and several QoL domain scores (p < 0.05).

CONCLUSION

This study highlights the prevalence of bowel dysfunction after Hartmann's reversal surgery. Patients undergoing this procedure show similar functional complaints compared to those in literature who had a resection without colostomy.

Impact of rurality and ethnicity on complexity of acute diverticulitis in Northland, New Zealand

BACKGROUND

Acute diverticulitis is a common general surgical condition associated with significant costs and healthcare burden. It is unknown if rurality represents a barrier to healthcare and whether ethnic disparities exist in Northland, New Zealand. This study, therefore, aims to assess the impact of rurality and ethnicity on complexity, management, and outcomes in patients with acute diverticulitis.

METHODS

A retrospective observational study of all adults aged >18 years admitted with acute diverticulitis to any Northland District Health Board hospital between 1 January 2015 and 31 December 2019 was performed. Diverticulitis complexity was assessed using the modified Hinchey classification. The primary outcome was the effect of rurality and ethnicity on complexity of diverticulitis. Multivariable logistic regression was performed.

RESULTS

A total of 397 patients (mean age 60.3 years (standard deviation (SD) 13.8); 48.7% female) were included. Overall, 134 patients had complicated diverticulitis. Rurality nor distance from the hospital were not associated with complexity of diverticulitis or clinical outcomes (p > 0.05). Maori patients presented younger than non-Maori (mean 51 vs. 63 years, p < 0.001) but there was no difference in complications, management, or clinical outcomes (p > 0.05). On multivariable analysis, rurality status and Maori ethnicity were not associated with more complicated diverticulitis.

CONCLUSION

This study found that rurality and ethnicity were not significant predictors of the complexity of diverticulitis.

Management of colonic diverticulitis

Left sided colonic diverticulitis is a common and costly gastrointestinal disease in Western countries, characterized by acute onset of often severe abdominal pain. Imaging is necessary to make an initial diagnosis and determine disease severity. Colonoscopy should be done six to eight weeks after diagnosis to rule out a missed colon malignancy. Antibiotic treatment is used selectively in immunocompetent patients with mild acute uncomplicated diverticulitis. The clinical course of diverticulitis commonly includes unpredictable recurrences and chronic gastrointestinal symptoms, which are a detriment to quality of life. A better understanding of prognosis has prompted a shift toward non-operative approaches. The decision to undergo prophylactic colon resection should be individualized to consider the severity of diverticulitis, the patient's health and immune status, and the patient's preferences and values, as well as benefits and risks. Because only a section of colon is removed, recurrent diverticulitis remains a risk. Acute diverticulitis with an abscess is treated with antibiotics that cover Gram negative and anaerobic bacteria, with or without percutaneous drainage. Acute diverticulitis with purulent or feculent contamination of the peritoneal cavity is managed with surgery; primary resection and anastomosis is the procedure of choice in stable patients.
