Curative resection after percutaneous drainage followed by preoperative panitumumab monotherapy for locally advanced sigmoid colon cancer with intra-abdominal abscess: a case report

BACKGROUND

The gold standard treatment for locally advanced colon cancer is curative surgery followed by adjuvant chemotherapy, although this approach is associated with serious concerns, such as high recurrence rates and occasionally unnecessary oversurgery. Neoadjuvant chemotherapy may be a promising strategy for overcoming these issues. This study reports a case of a recurrence-free patient who underwent curative resection without significant organ dysfunction after preoperative chemotherapy for locally advanced sigmoid colon cancer. The tumor coexisted with a large intra-abdominal abscess, and the patient was quite frail at the first visit. We performed percutaneous drainage followed by preoperative panitumumab monotherapy, which yielded favorable outcomes.

CASE PRESENTATION

A 78-year-old frail woman was emergently transferred to our hospital with fever and abdominal pain. The diagnosis was locally advanced sigmoid colon cancer stage IIIC (T4bN2aM0) with a large intra-abdominal abscess. Immediate curative surgery was inappropriate, considering both tumor progression and the patient's frailty. We performed percutaneous drainage and colostomy construction, which was followed by seven cycles of preoperative panitumumab monotherapy without significant adverse events. After these treatments, inflammation was well controlled, and the tumor shrank remarkably. Furthermore, the patient recovered well from frailty; therefore, curative sigmoidectomy combined with resection of the left ovary and stoma closure was possible without any postoperative complications. The final pathological finding was T3N0M0, stage IIA disease. The patient was recurrence-free and had no significant organ dysfunction 21 months after the curative surgery.

CONCLUSIONS

The management of intra-abdominal abscesses and tailor-made preoperative chemotherapy based on the patient's frailty may have been the key factors responsible for the favorable course of this patient. Although further research is needed on the appropriateness of percutaneous drainage for malignancies related to intra-abdominal abscesses and preoperative panitumumab use for locally advanced colon cancer, the study findings can serve as reference for managing similar cases in an aging society.

Unusual phenomenon-“polyp” arising from a diverticulum: A case report

BACKGROUND

Sealed perforation of colonic diverticulum is a common clinical condition and may be differentiated from an underlying malignant perforation using interval endoscopy. We present an uncommon colonoscopy finding of a healed diverticular perforation, mimicking a polyp, 6 wk post-diverticulitis-something that has not been reported in literature. We aim to shed light on the likely process that resulted in the trompe l'œil after diverticulitis. This also introduces the possibility of more targeted colonic resection in the event of a similar recurrence.

CASE SUMMARY

A middle-aged Chinese female presented with a 3-d history of non-colicky left iliac fossa pain. It was associated with fever (T_max 37.6 ºC), non-bloody diarrhoea and non-bloody, non-bilious vomiting. She had a history of Type 2 diabetes mellitus, well controlled on metformin. Tenderness was noted on the left iliac fossa region with no guarding or mass. Total white cell count (11.45 × 10⁹/L) and C-reactive protein levels (213.9 mg/L) were elevated. Computed tomography imaging of the abdomen revealed pericolonic fat stranding and extraluminal air pockets fluid density with peritoneal thickening at the sigmoid colon, likely representing a sealed perforation. Six weeks after the episode, she underwent a follow-up colonoscopy. An exophytic polypoid lesion closely associated with a diverticulum was seen in the sigmoid colon. The lesion was easily “pinched” off without much effort using endoscopic forceps and sent for histology which revealed granulation tissue suggesting a healed diverticular perforation.

CONCLUSION

Granulation tissue associated with healed diverticular perforations resemble polyps. Tattooing around these sites may allow for future targeted colonic resections.

Factors Predicting the Reversal of Hartmann’s Procedure

Aim

This paper investigates the risk factors preventing the reversal and nonreversal of Hartmann's procedure, as a surgical technique that has been performed in our clinic for ten years.

Methods

The study involved a ten-year Hartmann's procedure followed up at our center. The patients were divided into Hartmann reversal and nonreversal groups. Groups were examined in terms of age, gender, diagnosis, stage of malignancy, ASA score, comorbidity, perioperative morbidity-mortality, and the length of the operation.

Results

Age (p < 0.001), ASA score (p < 0.001), stage in case of malignancy (p = 0.002), and comorbidities (p < 0.001) were significant risk factors. The ratio of patients without any comorbidities to those with one or more comorbidities was 2.63 (95% CI 1.12–6.20). Among the malignant patients, the ratio of early-stage patients to advanced-stage patients in the group with reversal of Hartmann's colostomy was 2.82 (95% CI 1.30–6.10). In addition, the ratio of older patients to younger patients in group 2 was 0.95 (95% CI 0.92–0.98). A univariate analysis revealed that younger patients, those with lower ASA scores, those without comorbidities, and those with early-stage malignancy had a greater chance of closure of the stoma.

Conclusion

Although Hartmann's procedure is performed in emergency surgery, the nonreversal of the colostomy is a problem in itself. It should be kept in mind that patients who have high risks are likely to have a permanent stoma.

[Results of reconstructive surgery with formation of low colorectal anastomoses after previous Hartmann's procedure]

OBJECTIVE

To evaluate the efficacy and safety of original access to short rectal stump compared to traditional direct one.

MATERIAL AND METHODS

A retrospective-prospective cohort comparative study was conducted between 2012 and 2018. Inclusion criterion was previous Hartmann's procedure with formation of a short rectal stump. Short stump was determined by its length from anal-skin line to the cupola <7 cm. There were 93 patients who were divided into 2 groups: the main group - new approach (n=38), the control group - traditional direct approach (n=55). We analyzed surgery time, blood loss, intraoperative, early and late postoperative morbidity.

RESULTS

Surgery time and blood loss were similar in both groups (299.9 vs. 288.3 min, p=0.82; 204.5 vs. 112.4 ml, p=0.94, respectively). Intraoperative complications occurred in 7 patients of the control group (0 vs. 12.7% (7/55), p=0.02). Incidence of early postoperative complications was similar (28.9% (11/38) vs. 25.5% (14/55), p=0.71). Adverse events Clavien-Dindo grade I and IIIa were more common in the main group, grade IIIb and IVa - in the control group. Incidence of delayed postoperative complications were similar (10.5% (4/38) vs. 7.3% (4/55), p=0.58). Colorectal anastomosis stricture prevailed in the control group, ureteral stricture - in the main group. Neurophysiological and complex urodynamic examinations revealed no between-group differences.

CONCLUSION

The new method ensures access to the rectal stump and formation of colorectal anastomosis under direct visual control. Postoperative outcomes demonstrated safety and effectiveness of this technique.
