Short- and long-term outcomes in ypT2 rectal cancer patients after neoadjuvant therapy and local excision: a multicentre observational study.

BACKGROUND: Although local excision (LE) after neoadjuvant treatment (NT) has achieved encouraging oncological outcomes in selected patients, radical surgery still remains the rule when unfavorable pathology occurs. However, there is a risk of undertreating patients not eligible for radical surgery. The aim of this study was to evaluate the outcomes of patients with pathological incomplete response (ypT2) in a multicentre cohort of patients undergoing LE after NT and to compare them with ypT0-is-1 rectal cancers. METHODS: From 2010 to 2019, all patients who underwent LE after NT for rectal cancer were identified from five institutional retrospective databases. After excluding 12 patients with ypT3 tumors, patients with ypT2 tumors were compared to patients with ypT0-is-1 tumors). The endpoints of the study were early postoperative and long-term oncological outcomes. RESULTS: A total of 177 patients (132 males, 45 females, median age 70 [IQR 16] years) underwent LE following NT. There were 46 ypT2 patients (39 males, 7 females, median age 72 [IQR 18.25] years) and 119 ypT0-is-1 patients (83 males, 36 females, median age 69 [IQR 15] years). Patients with pathological incomplete response (ypT2) were frailer than the ypT0-is-1 patients (mean Charlson Comorbidity Index 6.15 ± 2.43 vs. 5.29 ± 1.99; p = 0.02) and there was a significant difference in the type of NT used for the two groups (long- course radiotherapy: 100 (84%) vs. 23 (63%), p = 0.006; short-course radiotherapy: 19 (16%) vs. 17 (37%), p = 0.006). The postoperative rectal bleeding rate (13% vs. 1.7%; p = 0.008), readmission rate (10.9% vs. 0.8%; p = 0.008) and R1 resection rate (8.7% vs. 0; p = 0.008) was significantly higher in the ypT2 group. Recurrence rates were comparable between groups (5% vs. 13%; p = 0.15). Five-year overall survival was 91.3% and 94.9% in the ypT2 and ypT0-is-1 groups, respectively (p = 0.39), while 5-year cancer specific survival was 93.4% in the ypT2 group and 94.9% in the ypT0-is-1 group (p = 0.70). No difference was found in terms of 5-year local recurrence free-survival (p = 0.18) and 5-year distant recurrence free-survival (p = 0.37). CONCLUSIONS: Patients with ypT2 tumors after NT and LE have a higher risk of late-onset rectal bleeding and positive resection margins than patients with complete or near complete response. However, long-term recurrence rates and survival seem comparable.

Treatment of haemorrhoids in pregnancy: A retrospective review.

AIM: Haemorrhoids are varicose veins of the rectum covered by mucosa at or near the anal canal. They are normally asymptomatic, can occur at any age and affect both males and females. Haemorrhoids are common in young women and commoner during pregnancy and the puerperium. In this review, we address the issue of the approach of the obstetrician and surgeons to haemorrhoids and their management. This is significant because there are currently no recommendations for pregnant patients with hemorrhoids. METHODS: The literature search comprised all the inherent published original papers; also abstract were included. No language selection was done. Search terms used were: "hemorrhoid", "hemorrhoid therapy", "hemorrhoid in pregnancy", "hemorrhoid complication". Data research was conducted using MEDLINE, EMBASE, Web of Sciences, Scopus, Clinical Trial. gov, OVID and Cochrane Library querying for all articles related to treatment of hemorrhoidis in pregnancy. RESULTS: Fiber supplement, stool softener and mild laxatives are generally safe for pregnant women. Topical medication or oral phlebotonics may be used with special caution because the strong evidence of their safety and efficacy in pregnancy is lacking. In case of massive bleeding, anal packing could be a simple and useful maneuver. Hemorrhoidectomy is reserved in strangulated or extensively thrombosed hemorrhoids, and hemorrhoids with intractable bleeding. KEY WORDS: Hemorrhoid, Hemorrhoid Therapy, Hemorrhoid in Pregnancy, Hemorrhoid Complication.

Robot-assisted laparoscopic subtotal gastrectomy for early-stage gastric cancer: Case series of initial experience.

BACKGROUND: In the last decade's robotic gastrectomy (RG) has increasingly widespread as a valid minimally invasive option for treatment of gastric cancer. In literature, evidence of its routine use is not yet well established. The aims of this study are to report our initial experience and to present possible advantages of our hybrid operative technique for subtotal gastrectomy. MATERIALS AND METHODS: Retrospectively, we analyzed data from 41 patients (22 male and 19 female) who underwent robot-assisted laparoscopic subtotal gastrectomy (RALG) with D2 lymphadenectomy using the da Vinci XI robotic system. Inclusion criteria were gastric cancer in the middle or lower portion of the stomach amenable of radical subtotal gastrectomy without preoperative suspicion of positive lymph-nodes or other organs involving and distant metastasis. All the procedures were performed by attending surgeons. RESULTS: The mean operative time was 270 min with one case of conversion to open surgery. The mean age was 71.4 (IQR 68.2-76.8) with 43.9% of patients classified as ASA (American Society of Anesthesiologists) score ≥3. The median of lymph-nodes retrieved was 25 (IQR 19-35). No intra-operative complications occurred. Time to resume a soft diet was 5 days. Patients were hospitalized a median of 7 days. According to pathological AJCC-TNM, 21 patients were classified as advanced gastric cancer. Post-operative morbidity was recorded in 9 patients (21.9%) with major complications requiring surgical operation in 4 patients (9.8%). Elevated ASA score, fewer lymph-nodes retrieved and ICU recovery requirements were significant increased in patients with major complications. CONCLUSION: The preliminary results demonstrated that robot-assisted laparoscopic subtotal gastrectomy is safe and feasible. In particular, we found that the da Vinci platform improves surgeon abilities to perform an adequate lymphadenectomy and digestive reconstruction. Further studies are necessary to better clarify the role of this high-cost technology in minimally invasive treatment of gastric cancer.
