Sir,

Retroperitoneal perforations of descending colon cancer (CCA) are exceedingly rare. Only one report of a flank abscess resulting from retroperitoneal perforation of descending CCA exists in the literature. [1] Ours appears to be the first United States' patient reported with this presentation. We describe our novel emergency management approach that ensured an excellent outcome for this patient.

A 44-year-old male patient presented with 3 weeks of left flank swelling, fevers and weight loss. He was tachycardic and hypotensive. Examination revealed rebound tenderness in the left lower quadrant and an erythematous fluctuant left flank mass. Laboratory investigation revealed leukocytosis to 39.4 × 10 3 /μL (normal <11 × 10 3 ) and hemoglobin 4.6 g/dL (normal >13.5). Computed tomography demonstrated a particulate 15.4 cm left retroperitoneal collection communicating with the descending colon through a focal perforation [Figure 1].{Figure 1}

After resuscitation and initiation of broad-spectrum antibiotics, an exploratory laparotomy was performed. A markedly inflamed segment in the mid-descending colon adherent to the retroperitoneum was mobilized, revealing a focal perforation. A left hemicolectomy was performed. The feculent retroperitoneum required wide debridement [Figure 2]a. We elected to leave the patient in colonic discontinuity and a temporary vacuum-assisted abdominal closure was performed. The patient was then turned to the right lateral decubitus position and external debridement of this collection was performed via an S-shaped counter-incision [Figure 2]b. The following day, an end transverse colostomy was performed, the left retroperitoneal defect sealed with a pedicled omental flap [Figure 2]c and the abdominal fascia closed. A vacuum-assisted closure device was employed to manage the left flank incision. Eventually, this incision was closed utilizing a myocutaneous advancement flap. Pathologic analysis revealed a margin-negative 2.8 cm adenocarcinoma with peritoneal invasion, but without nodal involvement (T4bN0M0). Having completed adjuvant chemotherapy with fluorouracil and oxaliplatin (FOLFOX), he remains disease-free 12 months after surgery.{Figure 2}

Despite well-established screening guidelines in the United States, up to 15-20% of CCA presents as obstruction and/or perforation. The incidence of perforated CCA is 2-9.6% in various series, and occurs either due to full-thickness necrosis at the tumor site or diastatic "blow-out" between an obstructing tumor and a competent ileocecal valve. [2] Perforated CCA is associated with higher perioperative mortality, local recurrence and peritoneal carcinomatosis although overall survival is similar to non-perforated cases after adjusting for perioperative mortality. [3] This suggests that the perioperative septic insult rather than tumor dissemination is more contributory to the worse prognosis with perforation. Although contained perforations have improved outcomes compared with free perforations, they present insidiously, pose diagnostic challenges and lead to interventional delays. Conceivably, inflammatory responses to bacterial contamination in extraperitoneal tissues are less exuberant than in the peritoneal cavity, causing non-specific symptoms that are not recognized immediately. [4]

For perforated descending colonic pathology, a Hartmann's procedure is recommended. If the diagnosis of CCA can be made pre-operatively, an oncologically appropriate operation should be attempted. Regardless of nodal status, adjuvant chemotherapy is recommended for locally advanced CCA. [5]

Although infectious causes are responsible for a majority of retroperitoneal abscesses in the developing world, bowel-related pathology - inflammatory bowel disease, diverticulitis, appendicitis, etc., - more commonly accounts for such abscesses in the italicize world. In the appropriate clinical setting, a flank abscess should also alert the astute clinician of retroperitoneal perforation from colonic malignancy.
