Laparoscopic total pelvic peritonectomy for colorectal cancer pelvic carcinomatosis: a retrospective case series and photographic/videographic step-by-step guide.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCytoreductive surgery (CRS) for colorectal cancer peritoneal carcinomatosis has been shown to prolong survival with acceptable morbidity rates. Total pelvic peritonectomy (TPP), or complete removal of all pelvic peritoneum, constitutes an important and technically challenging component of CRS. Here we report our experience and describe our technique of laparoscopic total pelvic peritonectomy (LTPP), using a photographic/videographic step-by-step guide.
methodsAll patients who underwent LTPP for pelvic carcinomatosis from a colorectal origin were included in the study. Only patients with peritoneal cancer index (PCI) score of ≤ 10 were selected for CRS with LTPP. Patients who had extra-abdominopelvic cavity metastases were excluded. The final decision to proceed with CRS was made following laparoscopic assessment.
resultsFrom January 2017 to December 2020, 15 consecutive patients underwent LTPP for colorectal cancer pelvic carcinomatosis. Median patient age and PCI score was 53 years (range 33-78) and 8 (range 3-10), respectively. Complete cytoreduction was achieved in all patients. Thirteen patients (87%) underwent concomitant hyperthermic intraperitoneal chemotherapy (HIPEC). The median operative duration was 748 min (interquartile range [IQR] 681-850). Median intra-operative blood loss and length of hospital stay was 100 ml (IQR 50-300) and 10 days (IQR 8-12), respectively. Five patients (33%) experienced 30-day post-operative morbidity, with one (6.7%) experiencing a higher grade (Clavien-Dindo IIIa) complication. Median follow-up duration was 13 months (IQR 3-19), during which four (27%) had systemic recurrence and one (6.7%) died after 15 months following peritoneal and systemic recurrences.
conclusionLTPP is a feasible option for low-volume pelvic carcinomatosis from colorectal cancer, offering the benefits of a minimally invasive approach. Strict patient selection is essential, and the procedure should be converted if the PCI score cannot be assessed or complete cytoreduction cannot be achieved. Proficiency at laparoscopic pelvic surgery is mandatory for performing LTPP.
