5 mm versus 10 mm umbilical port during laparoscopic cholecystectomy: do outcomes justify broader use in obese patients? A randomized controlled trial.
Trial report in Surgical endoscopy, 2025. 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
backgroundMini-laparoscopic cholecystectomy (MLC) is proposed as a modification for standard laparoscopic cholecystectomy to improve patient experience and postoperative outcomes. The aim of this study is to assess the feasibility and outcomes of performing laparoscopic cholecystectomy using 5 mm umbilical port and telescope in obese patients who are at higher risk for developing port-site complications while factoring in surgeon's satisfaction.
methods240 obese patients with chronic calcular cholecystitis were randomly allocated to two groups, standard laparoscopic cholecystectomy (SLC) group using 10 mm umbilical port, and MLC group using 5 mm one. The groups were analyzed for umbilical port-site hernia (PSH), postoperative pain, total operative time, and patient and surgeon satisfaction.
resultsThere were no conversions from MLC to SLC. None of the patients in the MLC group experienced port-site hernia compared to 6 patients in the SLC group (P = 0.03). MLC group had shorter total operative time (46 vs 52 min, P = 0.005), less pain during the first 24 h postoperative (P < 0.001), and fewer in-hospital analgesic requirements (P < 0.001). Duration of postoperative analgesia at home was shorter in MLC group (P < 0.001) with earlier return of patients to normal daily activities compared to SLC group (P < 0.001). Patient satisfaction and cosmesis were significantly higher among the MLC group (P < 0.001), however, surgeon satisfaction was inferior with the use of 5 mm telescopes compared to 10 mm ones (P = 0.06).
conclusionMini-laparoscopic cholecystectomy using 5 mm umbilical port and 5 mm telescope is safe and feasible among obese patients with uncomplicated gallstone disease. It offers shorter operative time, less postoperative pain and analgesic requirement, earlier return to normal daily activities, lower incidence of port-site hernia, and higher degree of patient satisfaction.
