Perforated Colon Cancer Associated With Post-operative Recurrent Bowel Perforations

Colon perforation is a major life-threatening condition associated with high morbidity and mortality, which often develops secondary to complicated diverticulitis and, less commonly, colon cancer. We describe the case of a 51-year-old female who had perforated colon cancer with concurrent diverticulosis. Based on history, physical exam, laboratory, and computed tomography (CT) findings on initial presentation, the patient was diagnosed with acute complicated diverticulitis. Despite medical treatment, the patient’s condition worsened, warranting exploratory laparotomy and a left hemicolectomy with transverse end colostomy creation. Surgical pathology revealed stage IIIC colon cancer without evidence of diverticulitis. The patient underwent eight cycles of adjuvant chemotherapy with FOLFOX (folinic acid, fluorouracil, and oxaliplatin). Over the next year, the patient experienced recurrent bowel perforations requiring repeated surgeries. Perforations were identified in both the small and large bowel on different occasions. Even though neither presented with a clear etiology, possible ischemic, infectious, erosive, and iatrogenic etiologies were on the differential. Our case exemplifies the mounting complications we should be wary of when performing repeated invasive abdominal operations.

Rare but relevant: a systematic review of stercoral perforation

BACKGROUND/AIMS

Knowledge of the aetiologies of large bowel perforation are fundamental to its management. Stercoral perforation is a rare cause associated with high mortality. Owing to the paucity of coverage of this condition in the literature, this review raises awareness of stercoral perforation among clinicians.

METHOD

A literature search of PubMed, Embase, MEDLINE, CINAHL, Ovid and Cochrane was performed. Key search terms included 'stercoral, perforation', 'perforated', 'perforat*' and 'stercoral perforation'. Only literature published between December 2011 and July 2020 was included to avoid duplication.

RESULTS

Twenty-nine papers were obtained giving an overall cohort of 58 patients. The median age was 58 years (range 2-83 years) and 72.4% (n=42) were female. Constipation was reported in 69% (n=40) and 20.7% (n=12) reported chronic opioid use. A computed tomography scan was performed in 94.8% (n=55) of cases and typically a Hartmann's procedure (n=40, 72.2%) was performed. The mortality rate was 17.2% (n=10).

CONCLUSIONS

The median age of patients with stercoral perforation has decreased from that found in previous studies and the mortality rate has improved. Chronic opioid users have also emerged as an important cohort. Early recognition, diligent decision making and focused perioperative care form the backbone of the definitive management of stercoral perforation.

Safety and feasibility of laparoscopic surgery for elderly rectal cancer patients in Japan: a nationwide study

Background

This study aimed to analyse the perioperative results from a national dataset of rectal cancer resections in elderly patients.

Methods

The clinical records of patients undergoing rectal cancer surgery between 2012 and 2014 were retrieved from the Japanese National Clinical Database and analysed retrospectively. Patients were categorized according to age and those 80 years or older were defined as elderly. Subgroups were also defined according to the surgical approach (laparoscopy versus open surgery). The short-term outcomes, including mortality, anastomotic leak, surgical site infections and medical complications were compared between subgroups.

Results

Of 56 175 patients undergoing rectal cancer surgery, some 6717 patients were elderly and laparoscopy was performed in 46.8 per cent of the sample. When comparing laparoscopy and open surgery in elderly patients, the operative mortality rate (1.5 versus 2.8 per cent; P < 0.001), the incidence of anastomotic leakage (5.2 versus 6.5 per cent; P = 0.026), surgical site infections (6.0 versus 8.0 per cent; P = 0.001), pneumonia (1.4 versus 2.5 per cent; P = 0.001), renal failure (0.7 versus 1.3 per cent; P = 0.016) and cardiac events (0.3 versus 0.8 per cent; P = 0.008) were lower for laparoscopy than for open surgery. The overall complication rate in elderly patients (19.5 per cent) was comparable to that in the younger group (P = 0.07). However, incidence of systemic complications was significantly higher in elderly than in younger patients (all P < 0.001).

Conclusion

Laparoscopy was safe and feasible in elderly patients compared with open surgery. However, the rates of systemic complications were significantly higher than in younger patients.
